PART I

 

ITEM 1.    BUSINESS

 

Overview  

 

We are a leading wireless and broadcast communications infrastructure company with a portfolio of approximately 15,000 towers, including pending transactions. Our primary business is leasing antenna space on multi-tenant communications towers to wireless service providers and radio and television broadcast companies. We operate the largest portfolio of wireless communications towers in North America and are the largest independent operator of broadcast towers in North America, based on number of towers. Our tower portfolio provides us with a recurring base of leasing revenues from our existing customers and growth potential due to the capacity to add more tenants and equipment to these towers. Our broad network of towers enables us to address the needs of wireless service providers on a national basis. We also offer select tower related services, such as antennae and line installation and site acquisition and zoning services, which are strategic to our core leasing business.

 

We intend to capitalize on the increasing use of wireless communication services by actively marketing space available for leasing on our existing towers and selectively developing or acquiring new towers that meet our return on investment criteria.

 

Our core leasing business, which we refer to as our rental and management segment, accounted for approximately 93.9% and 86.6% of our segment operating profit for the years ended December 31, 2002 and December 31, 2001, respectively. In 2003, we expect that our rental and management segment will contribute at least 95% of our segment operating profit, which we define as segment revenue less direct segment expense (rental and management segment operating profit includes interest income, TV Azteca, net – see notes 6 and 16 of the consolidated financial statements).

 

An element of our strategy is to continue to focus our operations on our rental and management segment by divesting non-core assets, using the proceeds to purchase high quality tower assets, and reducing outstanding indebtedness. Between January 1, 2002 and March 4, 2003, we completed approximately $203.5 million of non-core asset sales comprised of certain assets in our network development services and satellite and fiber network access services segments, more than 700 non-core towers, and two office buildings in our rental and management segment.

 

In December 2002, we committed to a plan to dispose of our wholly owned subsidiary, Verestar, which comprised our entire satellite and fiber network access services segment. Accordingly,Verestar is now accounted for as a discontinued operation. We plan to dispose of these assets within twelve months and have nominal, if any, commitment to invest additional funds in Verestar during the pendency of such divestiture, with the exception of financial guarantees of up to $12.0 million for certain contractual obligations. In addition, we are seeking to sell approximately $50.0 million of additional non-core assets during the remainder of 2003. We expect that a portion of the proceeds from our consummated and future non-core asset sales will be reinvested in higher quality tower assets.

 

We believe that this strategy of focusing our operations on our rental and management segment will make our consolidated operating cash flows more stable and provide us with continuing growth because of the following characteristics of our core leasing business:

 

    Long-term tenant leases with contractual escalators. In general, a lease with a wireless carrier has a duration of five to ten years and lease payments typically increase 3% to 5% per year.

Table of Contents

 

    Tower operating expenses are largely fixed. Incremental operating costs associated with adding wireless tenants to a tower are low.

 

    Low maintenance capital expenditures. On average, a wireless tower requires minimal annual capital investments to maintain.

 

    High lease renewal rates. Wireless carriers tend to renew leases because repositioning a site in a carrier’s network is expensive and often affects several other sites in the wireless network.

 

For more financial information about our business segments and geographic information about our operating revenues, segment operating profit and long-lived assets, see note 16 to our consolidated financial statements and “Management’s Discussion of Financial Condition and Results of Operations.”

 

Strategy

 

Our strategy is to capitalize on the increasing use of wireless communication services and the infrastructure requirements necessary to deploy current and future generations of wireless communication technologies. Between December 1995 and December 2002, the number of wireless phone subscribers in the United States increased from 33.8 million to 140.8 million. In addition, the minutes of use of wireless phone services among wireless carriers in the United States increased from 37.8 billion for the full year 1995 to nearly 619.0 billion for the full year 2002. From December 1995 through December 2002, the number of cell sites also increased from 22,700 to 139,300.* We expect that the continued growth of wireless subscribers and minutes of use of wireless personal communications and phone services will require wireless carriers to add a significant number of additional cell sites to maintain the performance of their networks in the areas they currently cover and to extend service to areas where coverage does not yet exist. In addition, we believe that as data wireless services, such as email and internet access, are deployed on a widespread basis, the deployment of these technologies will require wireless carriers to further increase the cell density of their existing networks, may require an overlay of new technology equipment, and may increase the demand for geographic expansion of their network coverage. To meet this demand, we believe wireless carriers will continue to outsource their tower infrastructure needs as a means of improving existing service coverage, implementing new technology, accelerating access to their markets and preserving capital, rather than constructing and operating their own towers and maintaining their own tower service and development capabilities.

 

We believe that our existing portfolio of towers, our tower related services and network development capabilities, and our management team, position us to benefit from these communication trends and to play an increasing role in addressing the needs of wireless service providers and broadcasters. The key elements of our strategy include:

 

   

Maximize Use of Our Tower Capacity. We believe that our highest returns will be achieved by leasing additional space on our existing towers. Annual rental and management revenue and segment operating profit growth during 2002 was 26% and 41%, respectively. We anticipate that our revenues and segment operating profit will continue to grow because many of our towers are attractively located for wireless service providers and have capacity available for additional antenna space rental that we can offer to customers at low incremental costs to us. Because the costs of operating a tower are largely fixed, increasing utilization significantly improves operating margins.

Table of Contents
 

We will continue to target our sales and marketing activities to increase utilization of, and investment return on, our existing towers.

 

    Actively Manage Our Tower Portfolio. We are actively managing our portfolio of towers by selling non-core towers and reinvesting a portion of the proceeds in high quality tower assets, such as the towers we are acquiring from NII Holdings. In 2002, we sold over 700 non-core towers. We also plan to pursue exchanges and sales of towers or tower clusters with tower operators and other entities. Our goal is to enhance operating efficiencies either by acquiring towers in regions where we have insufficient coverage or by disposing or exchanging towers in areas where we do not have operating economies of scale. If we are successful in disposing of certain tower assets, we may reinvest a portion of the proceeds received in more profitable tower assets.

 

    Employ Selective Criteria for New Tower Construction and Acquisitions. While our first priority is leasing capacity on our existing towers, we continue to construct and acquire new towers when our strict return on investment criteria can be met. These criteria include securing leases from the economic equivalent of two broadband customers in advance of construction, ensuring reasonable estimated construction costs and obtaining the land on which to build the tower, whether by purchase or ground lease, on reasonable terms.

 

    Continue Our Focus on Customer Service. Since speed to market and reliable network performance are critical components to the success of wireless service providers, our ability to assist our customers in meeting their goals will ultimately define our success. To that end, we intend to continue to focus on customer service by, for example, reducing cycle time for key functions, such as lease processing and antennae and line installations.

 

    Build On Our Strong Relationships with Major Wireless Carriers. Our understanding of the network needs of our wireless carrier customers and our ability to effectively convey how we can satisfy those needs are key to our efforts to add new antennae leases, cross-sell our services and identify desirable new tower development projects. We are building on our strong relationships with our customers to gain more familiarity with their evolving network plans so we can identify opportunities where our nationwide portfolio of towers, extensive service offerings and experienced construction personnel can be used to satisfy their needs. We believe that we are well positioned to be a preferred partner to major wireless carriers in leasing tower space and new tower development projects because of the location of our towers, our proven operating and construction experience and the national scope of our tower portfolio and services.

 

    Participation in Industry Consolidation. We believe there is compelling rationale for consolidation among tower companies. More extensive networks will be better positioned to provide more comprehensive service to customers and to support the infrastructure requirements of future generations of wireless communication technologies. Combining with one or more other tower companies also should result in improvements in cost structure efficiencies, with a corresponding positive impact on operating results. These benefits should, in turn, enhance access to capital and accelerate the de-levering process. Accordingly, we continue to be interested in participating in the consolidation of our industry on terms that are consistent with these perceived benefits and that create long-term value for our stockholders.

 

Operational Initiatives

 

In late 2001, we announced an initiative to accelerate the process of shifting our focus from acquisitions and development activities to operational execution.

 

Streamlined Administrative Functions.     During 2002, we simplified and streamlined our United States rental and management and services organizations, moving from five regions and twenty areas to three regions and ten areas by year end. We also centralized our lease processing and accounting operations into single locations, and integrated our construction unit and tower operations unit into a single unit. These initiatives yielded a significant increase in productivity per employee, improved margin performance, and resulted in faster and more consistent customer service.

Reduced Capital Spending.     We believe that our existing tower portfolio has the scope and available capacity to address a significant portion of our customers’ tower needs. We also believe that the highest investment returns can be achieved by adding tenants to our existing portfolio. As a result, we significantly reduced our capital expenditures on new tower development in 2002 and will continue to do so in 2003. We plan to build between 100 and 150 towers in 2003 in contrast to 311 towers (including ten broadcast towers) in 2002, and 1,319 towers (including five broadcast towers) in 2001. In addition, we expect our 2003 capital expenditures to continue to decrease to approximately $50.0 to $75.0 million, compared to total capital expenditures of approximately $180.5 million in 2002 and $568.2 million in 2001. We will continue to use more selective criteria for new tower development and will not undertake any development project unless it is likely to meet our heightened near-term return on investment criteria.

 

Products and Services

 

Our primary business is our leasing business, which we refer to as our rental and management segment. We also offer tower related services that are strategic to our rental and management segment through our network development services segment. In December 2002, we committed to a plan to dispose of our satellite and fiber network access services segment operations within the next twelve months and now account for the segment as a discontinued operation. See “Business—Satellite and Fiber Network Access Services (Discontinued Operations).”

 

Rental and Management

 

Leasing of Antennae Sites.    Our primary business is leasing antenna space on multi-tenant communications towers to wireless service providers and radio and television broadcast companies. Giving effect to pending transactions, we operate a tower network of approximately 15,000 multi-user sites in the United States, Mexico and Brazil, including more than 300 broadcast tower sites. Approximately 14,000 of these towers are owned or leased sites and approximately 1,000 are managed sites or lease/sublease sites under which we hold a position as lessee that terminates at the same time as a related sublease. Our networks in the United States and Mexico are national in scope. Our U.S. network spans 49 states and the District of Columbia. In addition, 84% of our U.S. network provides coverage in the top 100 markets or core areas such as high traffic interstate corridors. Giving effect to pending transactions, our Mexican network includes more than 1,600 sites in highly populated areas, including Mexico City, Monterrey, Guadalajara and Acapulco. Our Brazilian network consists of approximately 275 towers.

 

We lease antenna space on our towers to tenants in a diverse range of wireless communications and broadcast industries. Wireless industries we serve include: personal communications services, cellular, enhanced specialized mobile radio, specialized mobile radio, paging, fixed microwave and fixed wireless. Our major customers include ALLTEL, AT&T Wireless Services, Cingular Wireless, Nextel, Sprint PCS, T-Mobile (formerly called Voicestream) and Verizon and their respective affiliates.

 

The number of antennae that our towers can accommodate varies depending on the tower’s location, height, and the structural capacity at certain wind speeds. An antenna’s height on a tower and the tower’s location determine the line-of-sight of the antenna with the horizon and, consequently, the distance a signal can be transmitted. Some of our customers, such as personal communications services, enhanced specialized mobile radio providers and cellular companies in metropolitan areas, usually do not need to place their equipment at the highest tower point. Other customers, including paging companies and specialized mobile radio providers in rural areas, need higher elevations for broader coverage. We believe that many well-engineered and well-located towers built to serve the specifications of an initial anchor tenant in the wireless communications sector will accommodate three or more wireless tenants over time, thereby increasing revenue and enhancing margins.

 

Lease Terms.    Our leases, like most of those in the tower industry, generally vary depending upon the region and the industry user. Television and radio broadcasters prefer long term leases while wireless communications providers favor leases in the range of five to ten years in duration. In both cases, the leases often have multiple renewal terms at the option of the tenant. Both wireless carriers and broadcasters tend to renew

Table of Contents

their leases with us. Repositioning an antenna in a wireless carrier’s network is expensive and often requires reconfiguring several other antennae in the carrier’s network and may require the carrier to obtain other governmental permits.

 

Most of our leases have provisions that periodically increase the rent due under the lease. These automatic increases are typically annual and are based on a fixed percentage, inflation or a fixed percentage plus inflation.

 

Annual rental payments vary considerably depending upon:

 

    number and weight of the antennae on the tower and the size of the transmission line;

 

    ground space necessary to store equipment related to the antennae;

 

    existing capacity of the tower;

 

    the placement of the customer’s antenna on the tower;

 

    range or number of carrier’s frequency spectrum; and

 

    the location and height of the tower on which antenna space is rented.

 

Tower Development.    Historically, cellular and other wireless service providers had constructed and owned a majority of the towers for their own antennae needs, rather than leasing space on towers from a third party. Beginning in the late 1990s, wireless service providers expressed a growing interest in having independent companies own and operate the towers for their antennae, due to the relatively high capital costs and operating expenses for a single carrier’s use. This trend resulted in our entering into agreements with a number of wireless carriers to construct and subsequently lease space on towers in key areas identified as optimal for their network expansion requirements. In most cases, because we own the constructed towers, we are able to lease space on them to other tenants, as well as to the original tenant.

 

Network Development Services

 

We provide tower-related services that are strategic to our rental and management segment.

 

Antennae and Line Installation and Construction Services.    We are one of the leading builders of wireless communication and broadcast towers. As part of our network development services, we provide antennae and line installation and maintenance services for wireless communication towers and broadcast towers. These services use not only our construction-related skills, but also our technical expertise to ensure that new installations do not cause interference with other tenants. We believe that our antennae and line installation services and maintenance capabilities provide us with a significant opportunity to capture incremental revenue on existing and newly built sites.

 

In recent years, we have built a significant number of towers, predominantly for our own account. The cost of construction of a tower varies by site location and terrain, tower type and height, and any governmental and environmental requirements. Non-broadcast towers, whether on a rooftop or the ground, generally cost between $200,000 and $300,000 to construct. Broadcast towers are generally much taller, are built to bear a greater load, vary in height much more than non-broadcast towers, and cost significantly more than non-broadcast towers.

 

Site Acquisition and Zoning Services.    We engage in site acquisition services for our own account, in connection with tower development projects and other proprietary construction, as well as for third parties. With respect to new towers, the site selection and acquisition process begins with the network design. We identify highway corridors, population centers and topographical features within the carrier’s existing or proposed network and then select the most suitable sites, based on demographics, traffic patterns and the carrier’s frequency characteristics and technology. We also provide services related to zoning, structural engineering and construction.

Other Services and Infrastructure.    As part of our full service offering, we also provide radio frequency engineering, network design and tower-related consulting services through our Galaxy Engineering unit. In addition, we own and operate Kline Iron & Steel, an established steel fabricator that builds broadcast towers and provides steel for other construction projects.

 

Satellite and Fiber Network Access Services (Discontinued Operations)

 

Our Verestar subsidiary is a provider of integrated satellite and fiber network access services for telecommunications companies, internet service providers (ISPs), broadcasters, maritime customers, and governmental organizations, both domestic and international. We own and operate more than 175 satellite antennae at six satellite network access points in the United States and abroad. These operations enable us to access the majority of commercial satellites around the world.

 

In December 2002, we committed to a plan to sell Verestar, which comprised our satellite and fiber network access services segment, by December 31, 2003. Through the divestiture process, we will have nominal, if any, commitment to invest additional funds in Verestar, with the exception of approximately $12.0 million of Verestar’s contractual obligations that we have guaranteed. Depending on the terms of the final disposition, we may remain liable for these guarantees. We now account for Verestar as a discontinued operation and, accordingly, we no longer have a satellite and fiber network access services segment.

 

Recent Transactions

 

Acquisitions

 

NII Holdings, Inc.    In December 2002, we agreed to acquire approximately 540 communications sites, from NII Holdings, predominantly in Mexico, for an aggregate purchase price of $100.0 million in cash. As part of the transaction, we also agreed to provide up to 250 additional communication sites for NII Holdings’ incremental network build-out. We acquired 140 communication sites for approximately $26.2 million in December 2002, and an additional 147 communication sites for approximately $24.0 million as of March 4, 2003. The remaining communication sites are expected to close by the end of the third quarter of 2003. We continue to expect to fund the closings with proceeds from non-core asset sales.

 

Dispositions

 

From January 1, 2002 through March 4, 2003, we completed approximately $203.5 million of non-core asset sales. Significant dispositions included the following:

 

Non-Core Towers.    We disposed of over 700 non-core tower assets for approximately $25.0 million during 2002. These dispositions are part of our program to actively manage our portfolio of tower assets by selling non-core towers and reinvesting a portion of the total proceeds in high quality tower assets, such as the towers we are acquiring from NII Holdings.

 

MTS Components.    In July 2002, we sold MTS Components, part of our components business, for approximately $32.0 million, which consisted of approximately $20.0 million in cash paid at closing and  $12.0 million of notes receivable.

 

Office Buildings.     In December 2002, we sold the building where we maintain our corporate headquarters at 116 Huntington Avenue, Boston, Massachusetts. Proceeds from the sale were approximately $68.0 million, of which approximately $38.5 million was used to retire the existing mortgage indebtedness. In March 2003, we sold an additional office building for approximately $10.6 million. These buildings were primarily held as rental property in our rental and management segment.

 

Flash Technologies.    In January 2003, we sold Flash Technologies, our lighting systems business, for net cash proceeds of approximately $41.1 million, subject to a post-closing working capital adjustment.

Table of Contents

 

MTN.    In February 2003, we sold Maritime Telecommunications Network (MTN), a subsidiary of Verestar, for approximately $26.8 million in cash. The net proceeds from the sale were used to repay loans as required under our credit facilities.

 

Management Organization

 

Our corporate headquarters is in Boston, Massachusetts. In 2002, we streamlined our rental and management organization from five to three regions and from twenty to ten areas in the United States. Each region is headed by a vice president who reports to our Executive Vice President of Tower Operations who, in turn, reports to our President and Chief Operating Officer. Our current regional centers in the United States are based in Boston, Massachusetts, Chicago, Illinois and Phoenix, Arizona and are further subdivided into ten area operations centers that are staffed with skilled engineering, construction management and marketing personnel. Our centralized lease processing for the rental and management segment is based in Woburn, Massachusetts and our related accounting operations are based in Atlanta, Georgia. Our international regional centers are based in Mexico City, Mexico and Sao Paulo, Brazil. We believe our United States and international regional and area operations centers are capable of responding effectively to the opportunities and customer needs of their defined geographic areas.

 

Regulatory Matters

 

Towers and Licenses.    Both the Federal Communications Commission (“FCC”) and the Federal Aviation Administration (“FAA”) regulate towers used for wireless communications and radio and television broadcasting. These regulations govern the siting, lighting, marking and maintenance of towers. Depending on factors such as tower height and proximity to public airfields, the construction of new antenna structures or modifications to existing antenna structures must be reviewed by the FAA prior to initiation to ensure that the structure will not present a hazard to aircraft navigation. After the FAA issues a “No Hazard” determination, the tower owner must register the antenna structure with the FCC and paint and light the structure in accordance with the FAA determination. The FAA review and the FCC registration processes are prerequisites to FCC authorization of communications devices placed on the antenna structure. Tower owners bear the responsibility for notifying the FAA of any tower lighting failures and for the repair of those lighting failures. Tower owners also must notify the FCC when ownership of a tower changes. We generally indemnify our customers against any failure to comply with applicable standards. Failure to comply with applicable tower-related requirements may lead to monetary penalties.

 

The FCC separately regulates and licenses wireless communications devices and radio and television stations transmitting from the towers based upon the particular frequency used. We hold, through various subsidiaries, certain licenses for radio transmission facilities granted by the FCC, including satellite earth stations, private microwave and specialized mobile radio stations (which are subject to regulation by the FCC). We are required to obtain the FCC’s approval prior to assigning these licenses or transferring control of any entity of ours which holds FCC licenses.

 

The FCC considers the construction of a new tower or collocation of an antenna on an existing antenna structure (including building rooftops and watertanks) to be a federal undertaking subject to prior environmental review and approval under the National Environmental Policy Act of 1969 (“NEPA”), which obligates federal agencies to evaluate the environmental impacts of undertakings to determine whether they may significantly affect the environment. The FCC has issued regulations implementing NEPA as well as the National Historic Preservation Act, the Endangered Species Act and the American Indian Religious Freedom Act. These regulations place responsibility on each applicant or licensee to investigate potential environmental and other effects of operations and to disclose any significant impacts in an environmental assessment prior to constructing a tower or collocating an antenna. If a tower or collocation may have a significant impact on the environment, FCC approval of the tower or collocation could be significantly delayed. In January 2002, the FCC’s Wireless Bureau dismissed, for lack of standing, challenges to the registration of seven of our towers filed by certain environmental groups. The challenges alleged that we had failed to comply with NEPA and that the FCC’s rules

implementing NEPA are inadequate. The petitioners have appealed the Bureau’s decision to the FCC. If the Bureau’s decision is overturned, we could be subject to monetary penalties or increased compliance obligations. In August 2002, the same environmental groups asked the FCC to review the tower registrations of more than 5,000 towers in the gulf coast region to assess compliance with the Endangered Species Act and Migratory Bird Treaty Act and to require the filing of new or revised environmental assessments under NEPA for all towers in the region. We own a number of the towers identified in the pleading. However, because the pleading was not served on us, we have not been asked by the FCC to respond. PCIA, a trade association representing the tower industry, has asked the FCC to dismiss the pleading based on numerous grounds. The matter is pending. In February 2003, the same environmental groups filed suit against the FCC in a federal appeals court, asking the court to force the FCC to address the groups’ pending requests and appeals, and asked the court to force the FCC to adopt more stringent environmental rules. Depending on how the court rules, we could be subject to increased compliance obligations. In addition, a ruling in the federal appeals court could affect the groups’ pending cases with the FCC.

 

In January 2001, the FCC concluded investigations of several operators of communications towers, including us. The FCC sent us a Notice of Apparent Liability for Forfeiture (NAL) preliminarily determining that we had failed to file certain informational forms, had failed to properly post certain information at various tower sites, and on one occasion had failed to properly light a tower. The FCC also ordered an additional review of our overall procedures for and degree of compliance with the FCC’s regulations. We reached a settlement with the FCC regarding the compliance issues arising out of the NAL in the form of a Consent Decree. As part of the Consent Decree, the FCC has rescinded the NAL and terminated the further investigation ordered in the NAL. In September 2001 we made a voluntary contribution of $0.3 million to the U.S. Treasury and agreed to maintain an active compliance plan. Failure to comply with the Consent Decree may lead to additional monetary penalties and loss of the right to hold our various registrations and licenses.

 

The Telecommunications Act of 1996 amended the Communications Act of 1934 by limiting state and local zoning authorities’ jurisdiction over the construction, modification and placement of wireless communications towers. The law preserves local zoning authority but prohibits any action that would discriminate between different providers of wireless services or ban altogether the construction, modification or placement of communications towers. It also prohibits state or local restrictions based on the environmental effects of radio frequency emissions to the extent the facilities comply with FCC regulations. The Telecommunications Act of 1996 also requires the federal government to help licensees of wireless communications services gain access to preferred sites for their facilities. This may require that federal agencies and departments work directly with licensees to make federal property available for tower facilities.

 

We are also subject to local and county zoning restrictions and restrictive covenants imposed by local authorities or community developers. These regulations vary greatly, but typically require tower owners and/or licensees to obtain approval from local officials or community standards organizations prior to tower construction or collocations on existing towers. Local zoning authorities often are in opposition to construction in their communities and these regulations can delay or prevent new tower construction, collocations or site upgrade projects, thereby limiting our ability to respond to customer demand. In addition, those regulations increase costs associated with new tower construction and collocation. Existing regulatory policies may adversely affect the timing or cost of new tower construction and collocations, and additional regulations may be adopted which increase delays or result in additional costs to us. These factors could adversely affect our construction program and operations.

 

Our tower operations in Mexico and Brazil are also subject to regulation. If we pursue additional international opportunities, we will be subject to regulations in additional foreign jurisdictions. In addition, our customers, both domestic and foreign, also may be subject to new regulatory policies that may adversely affect the demand for communications sites.

Table of Contents

 

Satellite and Fiber Network Access (Discontinued Operations).    We are required to obtain licenses and other authorizations from the FCC for our use of radio frequencies to provide satellite and wireless services in the United States. We are also required to obtain authorizations from foreign regulatory agencies in connection with our provision of these services abroad. We hold a number of point-to-point microwave radio licenses that are used to provide telecommunications services. Additionally, we hold a number of satellite earth station licenses in connection with our operation of satellite-based networks. We are required to obtain consent from the FCC prior to assigning these licenses or transferring control of any of our companies holding an FCC license.

 

Environmental Matters.    Our operations, like those of other companies engaged in similar businesses, are subject to various federal, state and local and foreign environmental and occupational safety and health laws and regulations, including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials, and wastes, and the siting of our towers. As an owner, lessee and/or operator of real property and facilities, we may have liability under those laws for the costs of investigation, removal or remediation of soil and groundwater contaminated by hazardous substances or wastes. Certain of these laws impose cleanup responsibility and liability without regard to whether we, as the owner, lessee or operator, knew of or were responsible for the contamination, and whether or not we have discontinued operations or sold the property. We may also be subject to common law claims by third parties based on damages and costs resulting from off-site migration of contamination.

 

We, and our customers, also may be required to obtain permits, obey regulatory requirements, and make certain informational filings related to hazardous substances used at our sites by our customers. Violations of these types of regulations could subject us to fines and/or criminal sanctions. In October 2001, we paid $150,000 in civil penalties related to certain alleged environmental permitting and filing violations in the County of Santa Clara in California.

 

Health, Safety and Transportation.     As an FCC licensee, we are subject to regulations and guidelines imposing certain operational obligations relating to radio frequency emissions. As employers, we are subject to OSHA and similar guidelines regarding employee protection from radio frequency exposure. Our construction teams are subject to regulation by OSHA and equivalent state agencies concerning health and safety matters. Our heavy vehicles and their drivers are subject to regulation by the Department of Transportation.

 

Competition and New Technologies

 

Rental and Management Segment Competition.    We compete for antennae site customers with other national independent tower companies, wireless carriers that own and operate their own tower networks and lease tower space to other carriers, rooftop and other alternative site structures, site development companies that acquire space on existing towers for wireless service providers and manage new tower construction, and independent tower operators. We believe that tower location and capacity, price and quality of service historically have been and will continue to be the most significant competitive factors affecting owners, operators and managers of communications sites.

 

Network Development Services Segment Competition.    Our network development services compete with a variety of companies offering individual, or combinations of, competing services. The field of competitors includes site acquisition consultants, zoning consultants, real estate firms, right-of-way consulting firms, construction companies, tower owners/managers, radio frequency engineering consultants, telecommunications equipment vendors who can provide turnkey site development services through multiple subcontractors, and carriers’ internal staffs. We believe that carriers base their decisions on network development services on various criteria, including a company’s experience, track record, local reputation, price, and time for completion of a project. Kline Iron & Steel competes with numerous other steel fabricators, many of which have substantially greater resources.

 

We believe that we compete favorably as to the key competitive factors relating to our rental and management and network development services segments.

New Technologies.    The emergence or growth of new technologies could reduce the need for tower-based transmission and reception and may, therefore, have a negative impact on our operations. These technologies include: signal combining technologies, which permit one antenna to service two different frequencies of transmission and, thereby, two customers, may reduce the need for tower-based broadcast transmission and hence demand for tower space; technologies that enhance spectral capacity, such as beam forming or “smart antennas”, which can increase the capacity at existing sites and can reduce the number of additional sites a given carrier needs to serve any given subscriber base; delivery of wireless telephony services by direct broadcast satellites or cable providers, which could reduce the demand for tower space; indoor distribution systems, which relieve some capacity on existing networks and could have an adverse effect on our operations; and capacity enhancing technologies such as lower-rate vocoders and more spectrally efficient airlink standards, which potentially relieve network capacity problems without adding sites and could adversely affect our operations.

 

Any increase in the use of network sharing or roaming or resale arrangements by wireless service providers could adversely affect the demand for tower space. These arrangements, which are essentially extensions of traditional roaming agreements, enable a provider to serve customers outside its license area, to give licensed providers the right to enter into arrangements to serve overlapping license areas, and to permit non-licensed providers to enter the wireless marketplace. Wireless service providers might consider such sharing or resale arrangements superior to constructing their own facilities or leasing our antenna space. One possible benefit of such arrangements, however, is that network sharing arrangements could stimulate network development in areas where a single carrier network is economically unattractive.

 

Construction, Manufacturing and Raw Materials

 

We build, maintain and install land based wireless communications and broadcast transmitting and receiving facilities by obtaining sheet metal and other raw material parts and components from a variety of vendors. We also engage third party contract manufacturers to construct certain of these facilities. We have historically obtained the majority of our sheet metal and other raw materials parts and components from a limited number of suppliers. However, substantially all of these items are available from numerous other suppliers. We have not, to date, experienced any significant difficulties in obtaining the needed quantities of materials from suppliers in a timely manner.

 

Employees

 

As of December 31, 2002, we employed approximately 1,900 full time individuals and consider our employee relations to be satisfactory.

Factors That May Affect Future Results

 

Decrease in demand for tower space would materially and adversely affect our operating results and we cannot control that demand.

 

Many of the factors affecting the demand for wireless communications tower space, and to a lesser extent our services business, could materially affect our operating results. Those factors include:

 

    consumer demand for wireless services;

 

    the financial condition of wireless service providers;

 

    the ability and willingness of wireless service providers to maintain or increase their capital expenditures;

 

    the growth rate of wireless communications or of a particular wireless segment;

 

    the number of wireless service providers in a particular segment, nationally or locally;

 

    governmental licensing of broadcast rights;

 

    mergers or consolidations among wireless service providers;

 

    increased use of network sharing arrangements or roaming and resale arrangements by wireless service providers;

 

    delays or changes in the deployment of 3G or other technologies;

 

    zoning, environmental, health and other government regulations; and

 

    technological changes.

 

The demand for broadcast antenna space is dependent, to a significantly lesser extent, on the needs of television and radio broadcasters. Among other things, technological advances, including the development of satellite-delivered radio, may reduce the need for tower-based broadcast transmission. We could also be affected adversely should the development of digital television be delayed or impaired, or if demand for it were less than anticipated because of delays, disappointing technical performance or cost to the consumer.

 

Our substantial leverage and debt service obligations may adversely affect us.

 

We have a substantial amount of indebtedness. Our total indebtedness at year end, giving effect to our approximately $420.0 million offering of senior subordinated discount notes in January 2003 and the subsequent $200.0 million prepayment of term loans outstanding under our credit facilities, was approximately $3.6 billion, excluding any assumed repayment of other indebtedness out of the remaining proceeds from the discount notes offering.

 

Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay when due the principal of, interest on, or other amounts due in respect of our indebtedness. A significant portion of our outstanding indebtedness bears interest at floating rates. As a result, our interest payment obligations on such indebtedness will increase if interest rates increase. We may also obtain additional long term debt and working capital lines of credit to meet future financing needs. This would have the effect of increasing our total leverage. Our substantial leverage could have significant negative consequences, including:

 

    our inability to meet one or more of the financial ratios contained in our debt agreements or to generate cash sufficient to pay interest or principal, including periodic principal amortization payments, which events could result in an acceleration of some or all of our outstanding debt as a result of cross-default provisions;

 

12


Table of Contents

 

    increasing our vulnerability to general adverse economic and industry conditions;

 

    limiting our ability to obtain additional debt or equity financing;

 

    requiring the dedication of a substantial portion of our cash flow from operations to service our debt, thereby reducing the amount of our cash flow available for other purposes, including capital expenditures;

 

    requiring us to sell debt or equity securities or to sell some of our core assets, possibly on unfavorable terms, to meet payment obligations;

 

    limiting our flexibility in planning for, or reacting to, changes in our business and the industries in which we compete; and

 

    placing us at a possible competitive disadvantage with less leveraged competitors and competitors that may have better access to capital resources.

 

Our participation or inability to participate in tower industry consolidation could involve certain risks.

 

Any merger or acquisition transaction would involve several risks to our business, including demands on managerial personnel that could divert their attention from other aspects of our core leasing business, increased operating risks due to the integration of major national networks into our operational system, and potential antitrust constraints, either in local markets or on a regional basis, that could require selective divestitures at unfavorable prices. Any completed transaction may have an adverse effect on our operating results, particularly in the fiscal quarters immediately following its completion while we integrate the operations of the other business. In addition, once integrated, combined operations may not necessarily achieve the levels of revenues, profitability or productivity anticipated. There also may be limitations on our ability to consummate a merger or acquisition transaction. For example, any transaction would have to comply with the terms of our loan agreement and note indentures, and there are regulatory constraints on business combinations. Our inability to consummate a merger or acquisition for these or other reasons could result in our failure to participate in the expected benefits of industry consolidation and may have an adverse effect on our ability to compete effectively.

 

Continuation of the current U.S. economic slowdown could materially and adversely affect our business.

 

The existing slowdown in the U.S. economy has negatively affected the factors described under the prior heading, influencing demand for tower space and tower related services. For example, the slowdown, coupled with the deterioration of the capital markets, has caused certain wireless service providers to delay and, in certain cases, abandon expansion and upgrading of wireless networks, implementation of new systems, or introduction of new technologies. As a result, demand has also decreased for many of our network development services. The economic slowdown has also harmed, and may continue to harm, the financial condition of some wireless service providers. Many wireless service providers operate with substantial leverage and some wireless service providers, including customers of ours, have filed for bankruptcy.

 

If our wireless service provider customers consolidate or merge with each other to a significant degree, our growth, our revenue and our ability to generate positive cash flows could be adversely affected.

 

Significant consolidation among our wireless service provider customers may result in reduced capital expenditures in the aggregate because the existing networks of many wireless carriers overlap, as do their expansion plans. Similar consequences might occur if wireless service providers engage in extensive sharing or roaming or resale arrangements as an alternative to leasing our antennae space. In January 2003, the spectrum cap, which previously prohibited wireless carriers from owning more than 45 MHz of spectrum in any given geographical area, was allowed to expire. Some wireless carriers may be encouraged to consolidate with each other as a result of this regulatory change and as a means to strengthen their financial condition. Consolidation among wireless carriers would also increase our risk that the loss of one or more of our major customers could materially decrease revenues and cash flows.

Due to the long-term expectations of revenue from tenant leases, the tower industry is sensitive to the creditworthiness of its tenants.

 

Due to the long-term nature of our tenant leases, we, like others in the tower industry, are dependent on the continued financial strength of our tenants. During the past two years, several of our customers have filed for bankruptcy, although to date these bankruptcies have not had a material adverse effect on our business or revenues. Many wireless service providers operate with substantial leverage. If one or more of our major lease customers experienced financial difficulties, it could result in uncollectible accounts receivable and our loss of significant customers and anticipated lease revenues.

 

Restrictive covenants in our credit facilities, senior notes and senior subordinated discount notes could adversely affect our business by limiting flexibility.

 

The indentures for our senior notes, our senior subordinated discount notes issued in January 2003, and our credit facilities contain restrictive covenants and, in the case of the credit facilities, requirements of complying with certain leverage and other financial tests. These limit our ability to take various actions, including the incurrence of additional debt, guaranteeing indebtedness and issuing preferred stock, engaging in various types of transactions, including mergers and sales of assets, and paying dividends and making distributions or other restricted payments, including investments. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisition or other opportunities.

 

Our foreign operations could create expropriation, governmental regulation, funds inaccessibility, foreign exchange exposure and management problems.

 

Our expansion in Mexico and Brazil, and any other possible foreign operations in the future, could result in adverse financial consequences and operational problems not experienced in the United States. We have loaned $119.8 million to a Mexican company, own or have the economic rights to over 1,700 towers in Mexico, including approximately 200 broadcast towers (giving effect to pending transactions), and, subject to certain rejection rights, are contractually committed to construct up to approximately 650 additional towers in that country over the next three years. Giving effect to pending transactions, we also own or have acquired the rights to approximately 275 communications towers in Brazil and are, subject to certain rejection rights, contractually committed to construct up to 350 additional towers in that country over the next three years. The actual number of sites constructed will vary depending on the build out plans of the applicable carrier. In December 2002, we agreed to acquire approximately 540 communications sites from NII Holdings, predominantly in Mexico, for an aggregate purchase price of $100.0 million in cash. We may, should economic and capital market conditions improve, also engage in comparable transactions in other countries in the future. Among the risks of foreign operations are governmental expropriation and regulation, inability to repatriate earnings or other funds, currency fluctuations, difficulty in recruiting trained personnel, and language and cultural differences, all of which could adversely affect our operations.

 

New technologies could make our tower antenna leasing services less desirable to potential tenants and result in decreasing revenues.

 

The development and implementation of signal combining technologies, which permit one antenna to service two different transmission frequencies and, thereby, two customers, may reduce the need for tower-based broadcast transmission and hence demand for our antenna space. Technologies that enhance spectral capacity, such as beam forming or “smart antennas” can increase the capacity at existing sites and can reduce the number of additional sites a given carrier needs to serve any given subscriber base.

 

In addition, the emergence of new technologies could reduce the need for tower-based transmission and reception and have an adverse effect on our operations. The growth in delivery of video services by direct broadcast satellites could also adversely affect demand for our antenna space.

Table of Contents

 

Indoor distribution systems relieve some capacity on existing networks and could have an adverse effect on our operations. Capacity enhancing technologies such as lower-rate vocoders and more spectrally efficient airlink standards potentially relieve network capacity problems without adding sites and could adversely effect our operations.

 

We could have liability under environmental laws.

 

Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal, state and local and foreign environmental and occupational safety and health laws and regulations, including those relating to the management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances, materials, and wastes, and the siting of our towers. As owner, lessee or operator of approximately 15,000 real estate sites, we may be liable for substantial costs of remediating soil and groundwater contaminated by hazardous materials, without regard to whether we, as the owner, lessee or operator, knew of or were responsible for the contamination. In addition, we cannot assure you that we are at all times in complete compliance with all environmental requirements. We may be subject to potentially significant fines or penalties if we fail to comply with any of these requirements. The current cost of complying with those laws is not material to our financial condition or results of operations. However, the requirements of these laws and regulations are complex, change frequently, and could become more stringent in the future. It is possible that these requirements will change or that liabilities will arise in the future in a manner that could have a material adverse effect on our business, financial condition and results of operations.

 

Our business is subject to government regulations and changes in current or future laws or regulations could restrict our ability to operate our business as we currently do.

 

We are subject to federal, state, local and foreign regulation of our business, including regulation by the FAA, FCC, Environmental Protection Agency, Department of Transportation and OSHA. Both the FCC and the FAA regulate towers used for wireless communications and radio and television antennae and the FCC separately regulates transmitting devices operating on towers. Similar regulations exist in Mexico, Brazil and other foreign countries regarding wireless communications and the operation of communications towers. Local zoning authorities and community organizations are often opposed to construction in their communities and these regulations can delay, prevent or increase the cost of new tower construction, collocations or site upgrade projects, thereby limiting our ability to respond to customer demand. Existing regulatory policies may adversely affect the timing or cost of new tower construction and locations and additional regulations may be adopted which increase delays or result in additional costs to us or which prevent or restrict new tower construction in certain locations. These factors could adversely affect our operations.

 

Increasing competition in the tower industry may create pricing pressures that may adversely affect us.

 

Our industry is highly competitive, and our customers have numerous alternatives for leasing antenna space. Some of our competitors are larger and have greater financial resources than we do, while other competitors are in weak financial condition. Competitive pricing pressures for tenants on towers from these competitors could adversely affect our lease rates and service income. In addition, if we lose customers due to pricing, we may not be able to find new customers, leading to an accompanying adverse effect on our profitability. Increasing competition could also make the acquisition of high quality tower assets more costly.

 

Our competition includes:

 

    national independent tower companies;

 

    wireless carriers that own towers and lease antenna space to other carriers;

 

    site development companies that purchase antenna space on existing towers for wireless carriers and manage new tower construction; and

 

    alternative site structures (e.g., building rooftops, billboards and utility poles).

 

15


Table of Contents

 

We may not be able to maintain the leases for our tower sites.

 

Our property interests in our tower sites consist primarily of fee and leasehold interests, private easements and easements, licenses or rights-of-way granted by governmental entities. A loss of these interests, including losses arising from the bankruptcy of one or more of our lessors or from the default by one or more of our lessors under their mortgage financing, could interfere with our ability to conduct our business. We also may not be able to renew leases on favorable terms. In addition, we may not always have the ability to access, examine and verify all information regarding titles and other issues prior to completing a purchase or lease of tower sites.

 

Our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated.

 

Public perception of possible health risks associated with cellular and other wireless communications media could slow the growth of wireless companies, which could in turn slow our growth. In particular, negative public perception of, and regulations regarding, these perceived health risks could slow the market acceptance of wireless communications services and increase opposition to future siting efforts. The potential connection between radio frequency emissions and certain negative health effects has been the subject of substantial study by the scientific community in recent years. To date, the results of these studies have been inconclusive.

 

If a connection between radio frequency emissions and possible negative health effects, including cancer, were established, or if the public perception that such a connection exists were to increase, our operations, costs and revenues would be materially and adversely affected. We do not maintain any significant insurance with respect to these matters.

 

The market for our Class A common stock may be volatile.

 

The market price of our Class A common stock could be subject to wide fluctuations. These fluctuations could be caused by:

 

    quarterly variations in our results of operations;

 

    changes in earnings estimates by analysts;

 

    conditions in our markets; or

 

    general market or economic conditions.

 

In addition, in recent years the stock market has experienced extreme price and volume fluctuations. These fluctuations have had a substantial effect on the market prices of many companies, often unrelated to the operating performance of the specific companies. These market fluctuations could adversely affect the price of our Class A common stock.

 

If we issue a significant number of shares of Class A common stock to satisfy certain obligations under our convertible notes, the trading price for our Class A common stock could be adversely affected.

 

Holders of our three series of convertible notes, totaling $873.6 million outstanding at December 31, 2002, may require us to repurchase all or any of their convertible notes on dates and for the prices indicated in the discussion contained under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Certain Contractual Commitments.” Our credit facilities restrict our ability to repurchase convertible notes for cash, except that we now have the right to use up to $217.0 million to prepay or repurchase the 2.25% convertible notes and, to the extent we do not and are not required to do so, to prepay or repurchase prior to June 30, 2004, any of our other convertible notes or our senior notes. We may, subject to certain conditions in the applicable indentures (including the condition that our Class A common stock trade on a national securities exchange or Nasdaq), elect to pay the repurchase price in shares of Class A common stock. Exercising this election or seeking to reduce the amount of outstanding convertible notes

 

16


Table of Contents

prior to these dates may involve the issuance of a significant number of shares of our Class A common stock, or securities convertible into or exercisable for these shares, which could cause the trading price of our Class A common stock to decline.

 

There will be dilution of the value of our Class A common stock when outstanding warrants become exercisable.

 

In January 2003, we issued warrants to purchase approximately 11.4 million shares of our Class A common stock in connection with our 12.25% senior subordinated discount notes offering. The shares underlying the warrants represented approximately 5.5% of our outstanding common stock at issuance (assuming all the warrants are exercised). These warrants will become exercisable on or after January 29, 2006 at an exercise price of $0.01 per share (see note 19 to our consolidated financial statements). The issuance of these shares will have a dilutive effect on the value of our Class A common stock when these warrants are exercised.

 

If we are unable to sell our Verestar subsidiary, we may incur additional costs if we have to wind down and liquidate this business.

 

In December 2002, we committed to a plan to sell Verestar, which previously comprised our satellite and fiber network access services segment, within the next twelve months. With the exception of guarantees of approximately $12.0 million of Verestar’s contractual obligations, we will have nominal, if any, obligations to fund Verestar’s business through the divestiture process. If we are unable to sell Verestar prior to December 31, 2003, however, we may be forced to discontinue its operations and liquidate its assets. If this were to occur, we could incur additional costs in connection with the winding down and liquidation of Verestar’s businesses, and our management could be distracted from the operations of our core leasing business during this process.

 

ITEM 2.    PROPERTIES

 

We maintain our corporate headquarters at 116 Huntington Avenue, Boston, Massachusetts, where we lease approximately 30,000 square feet of office space. Prior to December 2002, we owned the building containing this office space. Our operating segments occupy headquarters or regional offices, warehouses and manufacturing space which we move into and out of from time to time as our business needs change. At present, the properties used in these business segments are as follows:

 

    Our rental and management segment is organized on a regional basis without maintaining a separate headquarters facility. Of these regional offices, we own (or we hold a majority interest in) an aggregate of approximately 34,800 square feet and lease an aggregate of approximately 39,100 square feet. Sales and tower operations for wireless carrier towers are located in three United States regional offices in Gilbert, Arizona, Schaumburg, Illinois and Boston, Massachusetts. Our international offices are located in Mexico City, Mexico and Sao Paulo, Brazil. The broadcast tower division’s office is located in Westwood, Massachusetts. Our lease processing center is located in Woburn, Massachusetts and our related accounting operations are located in Atlanta, Georgia.

 

    Our network development services segment does not maintain a headquarters but maintains key properties in: Columbia and West Columbia, South Carolina (where Kline Iron & Steel is located and maintains its steel manufacturing plant), and Alpharetta, Georgia where our engineering services business is located. We own an aggregate of approximately 639,000 square feet and lease an aggregate of approximately 330,000 square feet.

 

    Our former satellite and fiber network access services segment (discontinued operations) maintains its headquarters in Fairfax, Virginia in approximately 21,000 square feet of leased office space.

 

Our interests in individual communications sites are comprised of a variety of fee and leasehold interests. Of the approximately 15,000 towers comprising our portfolio, giving effect to pending transactions, approximately 19% are located on parcels of land that we own and approximately 81% are either located on parcels of land that

 

17


Table of Contents

we have leasehold interests created by long-term lease agreements, private easements and easements, licenses or rights-of-way granted by government entities, or are sites that we manage for third parties. In rural areas, a wireless communications site typically consists of 10,000 square feet tracts, which supports towers, equipment shelters and guy wires to stabilize the structure, whereas a broadcast tower site typically consists of a tract of land up to twenty-acres. Less than 2,500 square feet are required for a monopole or self-supporting tower structure of the kind typically used in metropolitan areas for wireless communication tower sites. Land leases generally have an initial term of five years with three or four additional automatic renewal periods of five years, for a total of twenty to twenty-five years.

 

Pursuant to our credit facilities, the lenders have liens on, among other things, all towers, leasehold interests, tenant leases, contracts relating to the management of towers for others, cash, accounts receivable, the stock and other equity interests of virtually all of our subsidiaries and all intercompany debt, fixtures, inventory and other personal property, including intellectual property, certain fee interests, and any proceeds of the foregoing.

 

We believe that our owned and leased facilities are suitable and adequate to meet our anticipated needs.

 

ITEM 3.    LEGAL PROCEEDINGS

 

We periodically become involved in various claims and lawsuits that are incidental to our business. We believe, after consultation with counsel, that no matters currently pending would, in the event of an adverse outcome, have a material impact on our consolidated financial position, results of operations or liquidity.

 

ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

 

No matters were submitted to a vote of our security holders in the fourth quarter of 2002.

Dividends

 

We have never paid a dividend on any class of common stock. We anticipate that we will retain future earnings, if any, to fund the development and growth of our business. We do not anticipate paying cash dividends on shares of common stock in the foreseeable future. Our borrower subsidiaries are prohibited under the terms of their credit facilities from paying cash dividends or making other distributions on, or making redemptions, purchases or other acquisitions of, their capital stock or other equity interests, including preferred stock, except that, beginning on April 15, 2004, if no default exists or would be created thereby under the credit facilities, our borrower subsidiaries may pay cash dividends or make other distributions to the extent that restricted payments, as defined in the credit facilities, do not exceed 50% of excess cash flow, as defined in the credit facilities, for the preceding calendar year. The 12.25% senior subordinated discount notes (issued in January 2003) of American Towers, Inc. (ATI), our principal operating subsidiary, impose similar limitations on the ability of ATI and certain of our subsidiaries that have guaranteed the discount notes (sister guarantors) to pay dividends and make other distributions. The indenture for our 9 3/8% senior notes due 2009 imposes significant limitations on the payment of dividends by us to our stockholders.

ITEM 6.     SELECTED FINANCIAL DATA

 

We have derived the following selected financial data from our audited consolidated financial statements, certain of which are included in this Annual Report on Form 10-K. You should read the selected financial data in conjunction with our “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and our audited consolidated financial statements and the related notes to those consolidated financial statements included in this Annual Report on Form 10-K. Prior to our separation from our former parent on June 4, 1998, we operated as a subsidiary of American Radio Systems Corporation (American Radio) and not as an independent company. Therefore, our results of operations and the financial condition information for that period may be different from what they would have been had we operated as a separate, independent company.

 

Our continuing operations are reported in two segments, rental and management and network development services. In December 2002, we committed to a plan to dispose of Verestar (previously comprising our entire satellite and fiber network access services segment) by sale within the next twelve months. In the fourth quarter of 2002, we also committed to a plan to sell Flash Technologies (previously included in the network development services segment) and two office buildings (previously included in our rental and management segment). In July 2002, we consummated the sale of MTS Components (previously included in our network development services segment). In accordance with generally accepted accounting principles, the consolidated statements of operations for all periods reported in this “Selected Financial Data” have been adjusted to reflect these businesses as discontinued operations.

 

Year-to-year comparisons are significantly affected by our acquisitions, dispositions and construction of towers. Our principal acquisitions and dispositions are described in “Business—Recent Transactions” and in the notes to our consolidated financial statements.

(1)   As of January 1, 2002, we adopted the provisions of SFAS No. 142, “Goodwill and Other Intangible Assets,” (SFAS No. 142). Accordingly, we ceased amortizing goodwill on January 1, 2002. The statements of operations for all periods presented except for the year ended December 31, 2002 include goodwill amortization. The adoption of SFAS No. 142 reduced amortization expense in continuing operations by approximately $70.0 million for the year ended December 31, 2002.
(2)   Tower separation expense refers to the one-time expense incurred as a result of our separation from American Radio.
(3)   Impairments and net loss on sale of long-lived assets for the year ended December 31, 2002 was $90.7 million and was comprised primarily of impairment charges and net loss on sale of certain non-core towers aggregating $46.8 million and an impairment charge of $40.2 million related to the write-off of construction-in-progress costs associated with approximately 800 sites that we no longer plan to build. Impairments and net loss on sales of long-lived assets for the year ended December 31, 2001 was $74.3 million and was primarily comprised of impairment charges on non-core towers of $11.7 million and an impairment charge of $62.6 million related to the write-off of construction in progress costs on sites that we no longer intended to build.
(4)   Represents the write-off of certain deferred financing costs associated with our term loan C credit facility which was terminated in 2002.
(5)   Note conversion expense represents the fair value of incremental stock issued to holders of our 2.25% and 6.25% convertible notes to induce them to convert their holdings prior to the first scheduled redemption date.
(6)   We computed basic and diluted loss per common share from continuing operations before extraordinary losses and cumulative effect of change in accounting principle using the weighted average number of shares outstanding during each period presented. Shares outstanding following the separation from our former parent American Radio are assumed to be outstanding for all periods presented prior to June 4, 1998. We have excluded shares issuable upon exercise of options and other common stock equivalents from the computations, as their effect is anti-dilutive.
(7)   Includes at December 31, 2001 and 2000 approximately $94.1 million and $46.0 million, respectively, of restricted funds required under our credit facilities to be held in escrow through August 2002 to fund scheduled interest payments on our outstanding senior and convertible notes.

ITEM  7.     MANAGEMENT’S   DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

 

The discussion and analysis of our financial condition and results of operations that follows are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses, and the related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ significantly from these estimates under different assumptions or conditions. This discussion should be read in conjunction with our consolidated financial statements and the accompanying notes thereto and the information set forth under the heading “Critical Accounting Policies” on page 40.

 

During the years ended December 31, 2002, 2001, and 2000, we acquired various communications sites, service businesses and satellite and fiber network access related businesses for aggregate purchase prices of approximately $55.7 million, $827.2 million, and $1.8 billion, respectively. Our results of operations only reflect the acquired towers and businesses in the periods following their respective dates of acquisition. As such, our results of operations for the year ended December 31, 2002 are not comparable to the year ended December 31, 2001, and the results for the year ended December 31, 2001 are not comparable to the year ended December 31, 2000.

 

Our continuing operations are reported in two segments, rental and management and network development services. Management focuses on segment profit (loss) as a means to measure operating performance in these business segments. We define segment operating profit (loss) as segment revenues less segment operating expenses excluding depreciation and amortization, corporate general and administrative expense, restructuring expense, development expense and impairments and net loss on sale of long-lived assets. Segment profit (loss) for the rental and management segment also includes interest income, TV Azteca, net (see note 16 to the consolidated financial statements).

 

In December 2002, we committed to a plan to dispose of Verestar (which previously comprised our entire satellite and fiber network access services segment) by sale within the next twelve months. In the fourth quarter of 2002, we also committed to a plan to sell Flash Technologies (previously included in our network development services segment) and two office buildings (previously included in our rental and management segment). In July 2002, we consummated the sale of MTS Components (previously included in our network development services segment). In accordance with generally accepted accounting principles, the consolidated statements of operations for periods reported in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” have been adjusted to reflect these businesses as discontinued operations.

Results of Operations

 

Years Ended December 31, 2002 and 2001

 

As of December 31, 2002, we owned or operated approximately 14,600 communications sites, as compared to approximately 14,500 communications sites as of December 31, 2001. The acquisitions and construction completed throughout 2001 and, to a lesser extent, 2002, have significantly affected operations for the year ended December 31, 2002, as compared to the year ended December 31, 2001.

Total Revenues

 

Total revenues for the year ended December 31, 2002 were $788.4 million, an increase of $3.3 million from the year ended December 31, 2001. The increase resulted from an increase in rental and management revenues of $113.6 million, offset by a decrease in network development services revenue of $110.3 million.

Table of Contents

 

Rental and Management Revenue

 

Rental and management revenue for the year ended December 31, 2002 was $548.9 million, an increase of $113.6 million from the year ended December 31, 2001. The increase resulted primarily from leasing activity on towers acquired and constructed subsequent to January 1, 2001 and, to a lesser extent, increased revenue on towers that existed as of January 1, 2001. The 4,270 towers that we have acquired and constructed since January 1, 2001 have significantly increased our revenues. The increased depth and strength of our national and international portfolio provided us with a much larger base of tower revenue for a full year in 2002 as compared to the year ended December 31, 2001. The remaining component of the increase is attributable to an increase in same tower revenue related to towers included in our portfolio as of January 1, 2001. This increase was driven by our ability to market and add additional tenants to those towers.

 

We continue to believe that our leasing revenue, which drives our core business, is likely to grow more rapidly than revenue from our network development services segment due to our expected increase in utilization of existing tower capacity. In addition, we believe that the majority of our leasing activity will continue to come from broadband type customers.

 

Network Development Services Revenue

 

Network development services revenue for the year ended December 31, 2002 was $239.5 million, a decrease of $110.3 million from the year ended December 31, 2001. The significant decline in revenues during 2002 resulted primarily from decreases in revenue related to construction management, installation, tower maintenance services and radio frequency engineering services, resulting from a corresponding decrease in the growth of the wireless telecommunications industry.

 

Total Operating Expenses

 

Total operating expenses for the year ended December 31, 2002 were $894.7 million, a decrease of $89.9 million from the year ended December 31, 2001. The principal component of the decrease was attributable to expense decreases in our network development services segment of $95.2 million. The remaining components of the decrease were attributable to decreases in depreciation and amortization of $29.1 million, as well as decreases in corporate general and administrative expense of $2.1 million and development expense of $2.0 million. These decreases were offset by increases in expenses within our rental and management segment of $16.7 million, coupled with increases in impairments and net loss on sale of long-lived assets of $16.5 million and restructuring expense of $5.4 million.

 

Rental and Management Expense/Segment Profit

 

Rental and management expense for the year ended December 31, 2002 was $228.5 million, an increase of $16.7 million from the year ended December 31, 2001. The majority of the increase resulted from incremental operating expenses incurred in 2002 for the more than 3,700 towers that were acquired or constructed during 2001 (due to a full year of inclusion in our results of operations in 2002). The balance of the increase reflects operating expenses incurred in 2002 for the more than 570 towers acquired/constructed in 2002. These increases were partially offset by cost reduction efforts in administrative and operational functions.

 

Rental and management segment profit for the year ended December 31, 2002 was $334.3 million, an increase of $96.5 million from the year ended December 31, 2001. The increase resulted primarily from incremental revenues and operating profit from both newly acquired and constructed towers and existing towers.

 

Network Development Services Expense/Segment Profit

 

Network development services expense for the year ended December 31, 2002 was $217.7 million, a decrease of $95.2 million from the year ended December 31, 2001. The majority of the decrease was due to an overall decline in demand for the services performed by this segment, as discussed above, coupled with decreases in overhead and related infrastructure costs.

Table of Contents

 

Network development services segment profit for the year ended December 31, 2002 was $21.8 million, a decrease of $15.1 million from the year ended December 31, 2001. The decrease resulted primarily from a decline in revenue, as discussed above, partially offset by a reduction in personnel, overhead and infrastructure costs as a result of restructuring initiatives that were implemented in 2002 and 2001.

 

Depreciation and Amortization

 

Depreciation and amortization for the year ended December 31, 2002 was $316.9 million, a decrease of $29.1 million from the year ended December 31, 2001. The decrease reflects the adoption of SFAS No. 142, which reduced amortization expense by approximately $70.0 million. This decrease was partially offset by an increase in depreciation expense related to the acquisition/construction of approximately $236.9 million of property and equipment in 2002 and a full year of depreciation on the $1.4 billion of property and equipment acquired in 2001.

 

Corporate General and Administrative Expense

 

Corporate general and administrative expense for the year ended December 31, 2002 was $24.3 million, a decrease of $2.1 million from the year ended December 31, 2001. The majority of the decrease is a result of cost reduction efforts in adminstrative and information technology functions related to our restructuring initiatives.

 

Restructuring Expense

 

In November 2001, we announced a restructuring of our organization to include a reduction in the scope of our tower development and acquisition activities and the centralization of certain operational and administrative functions. As a result of this continuing initiative, during the year ended December 31, 2002, we incurred employee separation costs associated with the termination of approximately 460 employees (primarily development and administrative), as well as costs associated with the termination of lease obligations and other incremental facility closing costs aggregating $10.6 million, an increase of $5.4 million from the year ended December 31, 2001.

 

As of December 31, 2002, we have completed our restructuring initiatives to consolidate operations and do not expect future charges associated with this restructuring.

 

Development Expense

 

Development expense for the year ended December 31, 2002 was $5.9 million, a decrease of $2.0 million from the year ended December 31, 2001. This decrease resulted primarily from reduced expenses related to tower site data gathering and acquisition costs as a result of our curtailed acquisition and development related activities.

 

Impairments and Net Loss on Sale of Long-Lived Assets

 

Impairments and net loss on sale of long-lived assets for the year ended December 31, 2002 was $90.7 million, an increase of $16.5 million from the year ended December 31, 2001. The increase was primarily attributable to an increase in impairment charges and net loss on sale of assets of approximately $35.1 million related to the write-down and sale of certain non-core towers, partially offset by a decrease in impairment charges of approximately $22.4 million related to the write-off of construction-in progress costs associated with sites that we no longer plan to build.

Interest Income

 

Interest income for the year ended December 31, 2002 was $3.5 million, a decrease of $25.1 million from the year ended December 31, 2001. The decrease resulted primarily from a decrease in interest earned on invested cash primarily attributable to a decrease in cash on hand during 2002, coupled with lower interest rates.

 

Interest Expense

 

Interest expense for the year ended December 31, 2002 was $255.6 million, a decrease of $12.2 million from the year ended December 31, 2001. The majority of the decrease, $26.6 million, resulted primarily from a reduction in the interest rates under our credit facilities. The decrease was partially offset by an increase of $7.6 million related to a full year of interest incurred on our senior notes (issued in January 2001) and a reduction in capitalized interest of $9.5 million as a result of our reduced capital expenditures in 2002.

 

Loss on Investments and Other Expense

 

Loss on investments and other expense for the year ended December 31, 2002 was $25.6 million, a decrease of $13.2 million from the year ended December 31, 2001. The decrease resulted primarily from decreased impairment and equity losses on our cost and equity investments offset by increased losses on foreign currency exchange related to our Mexican subsidiary.

 

Loss on Term Loan Cancellation

 

In January 2002, we terminated the $250.0 million multi-draw term loan C component of our credit facilities and recorded a non-cash charge of approximately $7.2 million related to the write-off of certain deferred financing fees associated with that component. No similar charge was incurred for the year ended December 31, 2001.

 

Note Conversion Expense

 

During the year ended December 31, 2001, we acquired a portion of our 2.25% convertible notes in exchange for shares of our Class A common stock. As a consequence of those negotiated exchanges with certain of our noteholders, we recorded a non-cash charge of $26.3 million. These charges represent the fair value of incremental stock issued to noteholders to induce them to convert their holdings prior to the first scheduled redemption date. No similar charge was incurred for the year ended December 31, 2002.

 

Income Tax Benefit

 

The income tax benefit for the year ended December 31, 2002 was $64.6 million, a decrease of $35.2 million from the year ended December 31, 2001. The effective tax rate was 17.0% for the year ended December 31, 2002, as compared to 20.4% for the year ended December 31, 2001. The decrease in the effective tax rate was primarily attributable to a valuation allowance of $27.5 million recorded in 2002 in connection with our plan to implement a tax planning strategy to accelerate the utilization of certain federal net operating losses (the valuation allowance represents the estimated lost tax benefit and costs associated with implementing this strategy). This decrease is offset by the impact of our ceasing to amortize goodwill (the majority of which is non-deductible for tax purposes) in 2002 in connection with the adoption of SFAS No. 142.

 

The effective tax rate on loss from continuing operations in 2002 differs from the statutory rate due primarily to valuation allowances related to our state net operating losses, capital losses, tax planning strategy and foreign items. The effective tax rate in 2001 differs from the statutory rate due to valuation allowances related to state net operating losses and capital losses and other non-deductible items consisting principally of goodwill amortization, and to a lesser extent, note conversion expense.

Table of Contents

 

SFAS No. 109, “Accounting for Income Taxes,” requires that we record a valuation allowance when it is “more likely than not that some portion or all of the deferred tax assets will not be realized.” At  December 31, 2002, we have provided a valuation allowance primarily related to state net operating loss carryforwards, capital loss carryforwards and the lost tax benefit and costs associated with implementing our tax planning strategy. We have not provided a valuation allowance for the remaining deferred tax assets, primarily federal net operating loss carryforwards, as management believes that we will have sufficient time to realize these assets during the carryforward period.

 

We intend to recover a portion of our deferred tax asset from our tax planning strategy to accelerate the utilization of certain federal net operating losses. The recoverability of our remaining net deferred tax asset has been assessed utilizing stable state (no growth) projections based on our current operations. The projections show a significant decrease in depreciation and interest expense in the later years of the carryforward period as a result of a significant portion of our assets being fully depreciated during the first fifteen years of the carryforward period and debt repayments reducing interest expense. Accordingly, the recoverability of our net deferred tax asset is not dependent on material improvements to operations, material asset sales or other non-routine transactions. Based on our current outlook of future taxable income during the carryforward period, management believes that our net deferred tax asset will be realized. The realization of our deferred tax assets as of December 31, 2002 will be dependent upon our ability to generate approximately $800.0 million in taxable income from January 1, 2003 to December 31, 2022. If we are unable to generate sufficient taxable income in the future, or accelerate the utilization of losses as contemplated in our tax planning strategy, we will be required to reduce our net deferred tax asset through a charge to income tax expense, which would result in a corresponding decrease in stockholders’ equity.

 

Loss from Discontinued Operations, Net

 

In December 2002, we committed to a plan to dispose of our wholly owned subsidiary Verestar by sale within the next twelve months. In the fourth quarter of 2002, we also committed to a plan to sell Flash Technologies and two office buildings held primarily as rental property. In July 2002, we consummated the sale of our MTS Components operations. Accordingly, we presented the results of these operations, $(249.9) million and $(60.2) million, net of tax, as loss from discontinued operations, net, in the accompanying statements of operations for the years ended December 31, 2002 and 2001, respectively. The net loss from discontinued operations for the year ended December 31, 2002 also includes a net loss on disposal from the sale of MTS Components and the two office buildings of approximately $13.5 million, net of a tax benefit.

 

All of these businesses held for sale as of December 31, 2002 and a subsidiary of Verestar were sold in the first quarter of 2003. We expect to sell the remaining portion of Verestar by December 31, 2003.

 

Extraordinary Loss on Extinguishment of Debt, Net

 

In February 2002, we repaid the $95.0 million outstanding under our Mexican Credit Facility with borrowings under our credit facilities. As a result of such repayment, we recognized an extraordinary loss on extinguishment of debt of approximately $1.1 million, net of an income tax benefit of $0.6 million for the year ended December 31, 2002. No similar losses were recorded in 2001.

 

Cumulative Effective of Change in Accounting Principle, Net

 

As of January 1, 2002, we adopted the provisions of SFAS No. 142 “Goodwill and Other Intangible Assets.” As a result, we recognized a $562.6 million non-cash charge (net of a tax benefit of $14.4 million) as the cumulative effect of change in accounting principle related to the write-down of goodwill to its fair value. The non-cash charge was comprised of goodwill within our satellite and fiber network access services segment ($189.3 million) and network development services segment ($387.8 million). In accordance with the provisions of SFAS No. 142, the charge is reflected as of January 1, 2002 and included in our results of operations for the year ended December 31, 2002.

Years Ended December 31, 2001 and 2000

 

As of December 31, 2001, we owned or operated approximately 14,500 communications sites, as compared to approximately 11,000 communications sites as of December 31, 2000. The acquisitions and construction completed in 2001 and 2000 have significantly affected operations for the year ended December 31, 2001, as compared to the year ended December 31, 2000.

Total Revenues

 

Total revenues for the year ended December 31, 2001 were $785.2 million, an increase of $275.2 million from the year ended December 31, 2000. The increase resulted from increases in rental and management revenues of $165.0 million and increases in network development services revenue of $110.2 million.

 

Rental and Management Revenue

 

Rental and management revenue for the year ended December 31, 2001 was $435.3 million, an increase of $165.0 million from the year ended December 31, 2000. The increase resulted primarily from leasing activity on towers acquired and constructed subsequent to January 1, 2000 and, to a lesser extent, increased revenue on towers that existed as of January 1, 2000. The 9,900 towers that we have acquired and constructed since January 1, 2000 have significantly increased our revenues. The increased depth and strength of our national and

 

29


Table of Contents

international portfolio provided us with a much larger base of tower revenue for a full year in 2001 as compared to the year ended December 31, 2000. The remaining component of the increase is attributable to an increase in same tower revenue related to towers included in our portfolio as of January 1, 2000. This increase was driven by our ability to market and add additional tenants to those towers.

 

Network Development Services Revenue

 

Network development services revenue for the year ended December 31, 2001 was $349.8 million, an increase of $110.2 million from the year ended December 31, 2000. The significant growth in revenues during 2001 resulted primarily from increased volume related to construction management, antennae and line installation and related collocation services, and tower site maintenance. The increase was also driven by a full year of revenue in 2001 related to acquisitions consummated in 2000, primarily a steel fabrication business. These increases were partially offset by decreases in revenue related to radio frequency engineering services.

 

Total Operating Expenses

 

Total operating expenses for the year ended December 31, 2001 were $984.6 million, an increase of $367.4 million from the year ended December 31, 2000. The increase was attributable to depreciation and amortization of $104.8 million, increases in expenses within rental and management of $75.5 million, network development services of $102.6 million, restructuring expense of $5.2 million, corporate general and administrative expense of $11.5 million and impairments and net loss on sale of long-lived assets of $74.3 million. These increases were offset by a decrease in development expense of $6.5 million.

 

Rental and Management Expense/Segment Profit

 

Rental and management expense for the year ended December 31, 2001 was $211.8 million, an increase of $75.5 million from the year ended December 31, 2000. The majority of the increase resulted from incremental operating expenses incurred in 2001 for the more than 6,200 towers that were acquired or constructed during 2000 (due to a full year of inclusion in our results of operations in 2001). The balance of the increase reflects operating expenses incurred in 2001 for the more than 3,700 towers acquired/constructed in 2001. These increases were partially offset by cost reduction efforts in administrative and operational functions.

 

Rental and management segment profit for the year ended December 31, 2001 was $237.9 million, an increase of $91.2 million from the year ended December 31, 2000. The increase resulted primarily from incremental revenues and operating profit from both newly acquired and constructed towers and existing towers.

 

Network Development Services Expense/Segment Profit

 

Network development services expense for the year ended December 31, 2001 was $312.9 million, an increase of $102.6 million from the year ended December 31, 2000. The majority of the increase resulted from overall increases in volume (as discussed above), incremental expenses related to the operations of acquisitions and increases in overhead costs necessary to support both internal construction and external sales.

 

Network development services segment profit for the year ended December 31, 2001 was $36.9 million, an increase of $7.6 million from the year ended December 31, 2000. The increase resulted primarily from an increase in the volume of services, as discussed above.

 

Depreciation and Amortization

 

Depreciation and amortization for the year ended December 31, 2001 was $346.0 million, an increase of $104.8 million from the year ended December 31, 2000. The principal component of the increase is an increase

 

30


Table of Contents

in depreciation expense of $86.7 million. This is primarily a result of our purchase, construction and acquisition of approximately $1.4 billion of property and equipment during 2001 and a full year of depreciation on acquisitions and additions made in 2000. The other component of the increase is increased amortization of $31.1 million, resulting from our recording and amortizing approximately $184.1 million of goodwill and other intangible assets related to acquisitions consummated during 2001, and a full year of amortization on goodwill and other intangible assets related to acquisitions made in 2000.

 

Corporate General and Administrative Expense

 

Corporate general and administrative expense for the year ended December 31, 2001 was $26.5 million, an increase of $11.5 million from the year ended December 31, 2000. The majority of the increase is a result of increased personnel and information technology costs to support our overall growth, coupled with expenses incurred to implement a new company-wide Enterprise Resource Planning (ERP) system.

 

Restructuring Expense

 

In November 2001, we announced a restructuring of our organization to include a reduction in the scope of our tower development and acquisition activities and the centralization of certain operating and administrative functions. As part of that initiative, we incurred employee separation costs relating to the termination of approximately 525 employees (primarily development and administrative), as well as costs associated with closing certain facilities, aggregating $5.2 million in the fourth quarter of 2001. No similar charges were incurred in 2000.

 

Development Expense

 

Development expense for the year ended December 31, 2001 was $7.9 million, a decrease of $6.5 million from the year ended December 31, 2000. This decrease resulted primarily from reduced expenses related to tower site, data gathering and acquisition integration in 2001.

 

Impairments and Net Loss on Sale of Long-Lived Assets

 

Impairments and net loss on sale of long-lived assets for the year ended December 31, 2001 was $74.3 million. The increase is attributed to non-cash impairment charges aggregating $11.7 million related to the write-down of certain non-core towers and a non-cash impairment charge of $62.6 related to the write-off of construction-in progress costs associated with sites that we no longer planned to build. No similar charges were incurred in 2000.

 

Interest Income, TV Azteca, Net

 

Interest income, TV Azteca, net for the year ended December 31, 2001 was $14.4 million, an increase of $1.7 million from the year ended December 31, 2000. The increase resulted from interest earned on the entire principal amount of the note, $119.8 million, during 2001 as compared to 2000 when less than the entire principal amount of the note was outstanding for the year.

 

Interest Income

 

Interest income for the year ended December 31, 2001 was $28.6 million, an increase of $12.7 million from the year ended December 31, 2000. The increase resulted primarily from an increase in interest earned on invested cash on hand, resulting principally from the sale of our senior notes in January 2001.

Table of Contents

 

Interest Expense

 

Interest expense for the year ended December 31, 2001 was $267.8 million, an increase of $116.1 million from the year ended December 31, 2000. The majority of the increase, $113.0 million, resulted primarily from increased borrowings outstanding under our credit facilities and the issue of $1.0 billion of senior notes in January 2001, offset by a decrease in interest rates under our credit facilities. The remaining component of the increase represented increases in interest on capital leases and other notes payable and incremental deferred financing amortization.

 

Loss on Investments and Other Expense

 

Loss on investments and other expense for the year ended December 31, 2001 was $38.8 million, an increase of $36.4 million from the year ended December 31, 2000. The increase resulted primarily from the write off of our investment in US Wireless of $23.4 million, coupled with additional investment impairment losses of $4.3 million and increases in losses on equity investments of $6.6 million.

 

Note Conversion Expense

 

During the year ended December 31, 2001, we acquired a portion of our 2.25% convertible notes in exchange for shares of our Class A common stock. As a consequence of those negotiated exchanges with certain of our noteholders, we recorded a non-cash charge of $26.3 million. In similar transactions during the year ended December 31, 2000, we acquired a portion of our 6.25% and 2.25% convertible notes in exchange for shares of our Class A common stock. As a result, we recorded a non-cash charge of $17.0 million during that year. These charges represent the fair value of incremental stock issued to noteholders to induce them to convert their holdings prior to the first scheduled redemption date.

 

Income Tax Benefit

 

The income tax benefit for the year ended December 31, 2001 was $99.9 million, an increase of $34.0 million from the year ended December 31, 2000. The primary reason for the increase is a result of the increase in our loss from continuing operations, partially offset by an increase in amortization of non-deductible intangible items. The effective tax rate on our loss from continuing operations was 20.4% for the year ended December 31, 2001, as compared to 26.4% for the year ended December 31, 2000.

 

The effective tax rate on loss from continuing operations in 2001 differs from the statutory rate due to certain non-deductible amounts for tax purposes such as the valuation allowances related to state net operating losses, capital losses and the effects of other non-deductible items such as goodwill amortization and note conversion expense. The effective tax rate in 2000 differs from the statutory rate due to the recording of valuation allowances related to state net operating losses and other non-deductible items consisting principally of goodwill amortization, and to a lesser extent, note conversion expense.

 

SFAS No. 109, “Accounting for Income Taxes,” requires that we record a valuation allowance when it is “more likely than not that some portion or all of the deferred tax assets will not be realized.” At December 31, 2001, we have provided a valuation allowance primarily related to state net operating loss carryforwards and capital losses. We have not provided a valuation allowance for the remaining deferred tax assets, primarily federal net operating loss carryforwards, as management believes that we will have sufficient time to realize these assets during the carryforward period.

 

As of December 31, 2001, the recoverability of our net deferred tax asset has been assessed utilizing stable state (no growth) projections based on our current operations. The projections show a significant decrease in depreciation and interest expense in the later years of the carryforward period as a result of a significant portion of our assets being fully depreciated during the first fifteen years of the carryforward period and debt repayments

reducing interest expense. Accordingly, the recoverability of our net deferred tax asset is not dependent on material improvements to operations, material asset sales or other non-routine transactions. Based on our current outlook of future taxable income during the carryforward period, management believes that its net deferred tax asset will be realized. The realization of our deferred tax assets as of December 31, 2001 will be dependent upon our ability to generate approximately $740.0 million in taxable income from January 1, 2002 to December 31, 2021. If we are unable to generate sufficient taxable income in the future we will be required to reduce our net deferred tax asset through a charge to income tax expense, which would result in a corresponding decrease in stockholders’ equity.

 

Loss from Discontinued Operations, Net

 

In December 2002, we committed to a plan to dispose of our wholly owned subsidiary Verestar by sale within the next twelve months. In the fourth quarter of 2002, we also committed to a plan to sell Flash Technologies and two office buildings held primarily as rental property. In July 2002, we consummated the sale of MTS Components. Accordingly, we presented the results of these operations, $(60.2) million and $(6.2) million, net of tax, as loss from discontinued operations, net, in the accompanying statements of operations for the years ended December 31, 2001 and 2000, respectively.

 

Extraordinary Losses on Extinguishment of Debt, Net

 

We incurred extraordinary losses on the extinguishment of debt, net in 2000 of $4.3 million. The losses were incurred as a result of an amendment and restatement of our primary credit facilities ($3.0 million, net of a tax benefit of $2.0 million) and our early retirement of debt ($1.3 million, net of a tax benefit of $0.9 million). No comparable losses were recorded in 2001.

 

Liquidity and Capital Resources

 

Liquidity Overview

 

Our primary sources of liquidity have been internally generated funds from operations, borrowings under our credit facilities, proceeds from equity and debt offerings, proceeds from the sale of non-core assets and cash on hand. We have used those funds to meet our capital requirements, which consist primarily of operational needs, debt service and capital expenditures for tower construction and acquisitions.

 

In the fourth quarter of 2002, we generated sufficient cash flow from operations to fund our capital expenditures and service our cash interest expense. We believe cash flow from operations in 2003 will be sufficient to fund our capital expenditures and cash interest payments for that year.

 

In January 2003, we completed an offering (discount note offering) of approximately $420.0 million, consisting of 12.25% senior subordinated discount notes due 2008 (discount notes) of ATI and warrants to purchase 11.4 million shares of our Class A common stock. In connection with the financing, we obtained an amendment of our credit facilities (credit agreement amendment). Pursuant to the credit agreement amendment, we repaid $200.0 million of term loans outstanding under our credit facilities and reduced our revolving loan commitments by $225.0 million to $425.0 million. That amendment also gives us the right to use $217.0 million, which we have placed in escrow for that purpose, to purchase our 2.25% convertible notes on or prior to October 22, 2003, at which time the holders have the right to put those notes to us. We may elect to satisfy all or a portion of our obligations with respect to the 2.25% convertible notes through the issuance of shares of our Class A common stock (subject to certain restrictions) on October 22, 2003 pursuant to the put right or, prior to that time, pursuant to a limited number of privately negotiated transactions. We also may use any escrowed funds not used to purchase 2.25% convertible notes to purchase, prior to June 30, 2004, our other convertible notes and our senior notes. We are required to use any funds remaining in escrow on June 30, 2004 to reduce our term loans under the credit facilities.

Table of Contents

 

We expect our 2003 capital needs to consist primarily of the following: debt service, including cash interest of approximately $215.0 million, repayment of approximately $54.4 million of term loans under our amended credit facilities and up to $217.0 million of 2.25% convertible notes (assuming all holders exercise their put rights); capital expenditures of between $50.0 and $75.0 million; and tower acquisitions of approximately $74.0 million. We expect to meet those needs through a combination of cash on hand of approximately $127.3 million at December 31, 2002, remaining net proceeds from the discount note offering of approximately $197.0 million (after the repayment of $200.0 million of term loans), cash generated by operations, proceeds from sales of non-core assets, and nominal, if any, borrowings under our credit facilities. Due to the risk factors outlined above, however, there can be no assurance that we will be able to meet our capital needs without additional borrowings under our credit facilities.

 

Uses of Liquidity

 

Our principal uses of liquidity, in addition to funding operations, are debt service and capital expenditures for tower construction and acquisitions.

 

Debt Service.    As of December 31, 2002, we had outstanding debt of approximately $3.5 billion, consisting of the following:

 

    credit facilities—$1.5 billion;

 

    senior notes—$1.0 billion;

 

    convertible notes, net of discount—$873.6 million; and

 

    other—$81.0 million (primarily capital leases and notes payable).

 

Our debt instruments require us to make current interest payments and significant principal payments at their respective maturities. In addition, in the case of our credit facilities, we must make scheduled amortization payments in increasing amounts designed to repay the loans at maturity. During 2003, we will be required to repay approximately $13.6 million of the amended term loans each quarter.

 

Prior to maturity, there are no mandatory redemption provisions for cash in the senior notes, the convertible notes or the discount notes. The holders of the convertible notes, however, have the right to require us to repurchase their notes on specified dates prior to maturity, but we may at our election pay the repurchase price in cash or by issuing shares of our Class A common stock, subject to certain conditions in the applicable indenture. Our credit facilities restrict our ability to repurchase convertible notes for cash, except that we now have the right to use up to $217.0 million to prepay or repurchase the 2.25% convertible notes and, to the extent we do not and are not otherwise required to do so, to prepay or repurchase prior to June 30, 2004, any of our other convertible notes or our senior notes.

 

Tower Construction and Acquisition Needs.    We have significantly reduced our planned level of tower construction and acquisitions for 2003 from prior years. As a result, we anticipate that our liquidity needs for new tower development and acquisitions during 2003 will be significantly less than in previous periods.

 

    Construction.  In 2003, we expect to build between 100 and 150 towers (including broadcast towers) and expect total capital expenditures to be between $50.0 million and $75.0 million.

 

    Acquisitions. As of December 31, 2002, we were committed to make expenditures of approximately $74.0 million for pending acquisitions, principally the NII Holdings transaction, of which approximately $24.0 million had been paid as of March 4, 2003.

 

Sources of Liquidity

 

We expect to meet our cash requirements for 2003 through a combination of cash on hand, net proceeds from the discount note offering, cash generated by operations, proceeds from sales of non-core assets, and nominal, if any, borrowings under our credit facilities.

Table of Contents

 

Cash on Hand.    As of December 31, 2002, we had approximately $127.3 million in cash on hand. As a result of the net proceeds from the discount note offering and the $200.0 million repayment of term loans under our credit facilities described above, we had approximately $324.3 million of cash on hand, including $217.0 million in escrow. As explained above, while we have the right to use up to $217.0 million of the escrowed funds to purchase the 2.25% convertible notes, we may elect to satisfy all or a portion of our obligations with respect to those notes through the issuance of shares of our Class A common stock.

 

Cash Generated by Operations.    We expect our cash flow needs by segment for 2003 to be as follows (excluding cash requirements to fund debt service, as interest expense is not allocated to our segments). Our rental and management and network development services segments are expected to generate cash flows from operations during 2003 in excess of their cash needs for operations and capital expenditures. We expect to use the excess cash generated from these segments principally to service our debt. Effective December 31, 2002, we committed to a plan to dispose of our satellite and fiber network access services segment. Accordingly, these operations are reflected as discontinued operations in our consolidated financial statements. The businesses in our former satellite and fiber network access services segment are expected to be near cash flow break-even from operations, but may require additional sources of liquidity to fund minimal capital expenditures until final disposition. In addition, we currently provide financial guarantees of up to $12.0 million for certain Verestar contractual obligations. Depending on the terms of any disposition, we may continue to be obligated with respect to those guarantees.

 

Divestiture Proceeds.    We are continuing to pursue strategic divestitures of non-core assets in an effort to enhance efficiency and increase our focus on our core tower operations. Through March 4, 2003, we completed approximately $203.5 million in non-core asset sales (including approximately $78.5 million subsequent to December 31, 2002) related to (a) our two components businesses, (b) a Verestar subsidiary, (c) our corporate office building and other real estate assets, and (d) non-core towers. Proceeds from those and any future transactions have and will be used, to the extent permitted under our credit facilities and mortgages, to fund capital expenditures for tower construction and acquisitions. We anticipate approximately $50.0 million of proceeds from additional sales of non-core assets during the remainder of 2003.

 

Credit Facilities.  As of December 31, 2002, we had drawn $160.0 million of the $650.0 million revolving line of credit under our credit facilities (the only component of our credit facilities which is not fully drawn). We also had outstanding letters of credit of $19.2 million as of December 31, 2002. Availability under our revolving line of credit as of December 31, 2002, was $470.8 million, net of $19.2 million of outstanding letters of credit. The credit agreement amendment decreased the revolving loan commitment to $425.0 million, thereby reducing availability to $245.8 million.

 

Cash Flows Summary

 

For the year ended December 31, 2002, cash flows provided by operating activities were $105.1 million, as compared to $26.1 million for the year ended December 31, 2001. The increase is primarily due to an increase in cash flow generated from our rental and management segment, coupled with a decrease in our overall investment in working capital.

 

For the year ended December 31, 2002, cash flows used for investing activities were $115.3 million, as compared to $1.4 billion for the year ended December 31, 2001. The decrease is primarily due to a decrease in cash expended for acquisitions, property and equipment and construction activities, coupled with an increase in proceeds received from the sale of non-core businesses and assets.

 

For the year ended December 31, 2002, cash flows provided by financing activities were $101.4 million, as compared to $1.4 billion for the year ended December 31, 2001. The decrease is primarily related to a reduction in proceeds from the issuance of debt and equity securities.

Certain Contractual Commitments

 

Below is a summary of certain provisions of our credit facilities, discount notes, senior notes, convertible notes and certain other contractual obligations. It is qualified in its entirety by the terms of the actual agreements which have been filed as exhibits to this Annual Report on Form 10-K. For information about the restrictive covenants in our debt instruments, see “Factors Affecting Sources of Liquidity.” For more information about our obligations, commitments and contingencies, see our consolidated financial statements herein and the accompanying notes thereto and “Quantitative and Qualitative Disclosures About Market Risk” for principal payments and contractual maturity dates as of December 31, 2002.

 

Credit Facilities.  Our credit facilities (prior to the February 2003 credit agreement amendment), provided us with a borrowing capacity of up to $2.0 billion (after giving effect to the amendment — $1.575 billion). Our principal operating subsidiaries (other than Verestar) are the borrowers under our credit facilities. Borrowings under the credit facilities are subject to compliance with certain financial ratios as described below. Our credit facilities currently include:

 

    a $650.0 million (as amended — $425.0 million) revolving credit facility, of which $160.0 million was drawn and against which $19.2 million of undrawn letters of credit were outstanding on December 31, 2002, maturing on June 30, 2007;

 

    an $850.0 million (as amended — $725.0 million) multi-draw term loan A, which was fully drawn on December 31, 2002, maturing on June 30, 2007; and

 

    a $500.0 million (as amended — $425.0 million) term loan B, which was fully drawn on December 31, 2002, maturing on December 31, 2007.

 

We are required under our credit facilities to make scheduled amortization payments in increasing amounts designed to repay the loans at maturity. During 2003, we will be required to repay approximately $13.6 million of the amended term loans each quarter.

 

We and our restricted subsidiaries, as well as Verestar and its subsidiaries, have guaranteed all of the loans under our credit facilities. We have secured the loans by liens on substantially all assets of the borrowers and the restricted subsidiaries, as well as Verestar and its subsidiaries, and substantially all outstanding capital stock and other debt and equity interests of all of our direct and indirect subsidiaries.

 

The amended credit facilities permit us to use up to $217.0 million to repurchase the 2.25% convertible notes. We may use any escrowed funds not used to purchase 2.25% convertible notes to purchase, prior to  June 30, 2004, our other convertible notes and our senior notes. We are required to use any escrowed funds remaining at June 30, 2004 to reduce our term loans under the credit facilities.

 

Discount Notes and Warrants.  In January 2003, American Towers, Inc. (ATI), our principal operating subsidiary, issued 12.25% senior subordinated discount notes due 2008 with a principal amount at maturity of $808.0 million. The discount notes will mature on August 1, 2008. No cash interest is payable on the discount notes. Instead, the accreted value of each discount note increases between the date of original issuance and the maturity date at a rate of 12.25% per annum.

 

The discount notes rank junior in right of payment to all existing and future senior indebtedness of ATI, the sister guarantors and their domestic subsidiaries and structurally senior in right of payment to all of our existing and future indebtedness. The discount notes are jointly and severally guaranteed on a senior subordinated basis by us and all of our wholly owned domestic subsidiaries, other than Verestar and its subsidiaries.

 

As part of the discount notes offering, we issued warrants to purchase an aggregate of 11.4 million shares of our Class A common stock at a price of $0.01 per share. The warrants and the discount notes were originally issued together as 808,000 units, each unit consisting of (1) one discount note having a principal value of $1,000

 

36


Table of Contents

at maturity, and (2) one warrant to purchase 14.0953 shares of our Class A common stock at $0.01 per share. The warrants are exercisable at any time on or after January 29, 2006 and will expire on August 1, 2008. At the time of issuance, the warrants represented approximately 5.5% of our outstanding common stock (assuming exercise of all warrants). The holders of the discount notes and the warrants have registration rights requiring us to file registration statements with respect to the discount notes and warrants and subjecting us to penalties if such registration statements are not timely filed and declared effective by the Securities and Exchange Commission.

 

9 3/8% Senior Notes.  As of December 31, 2002, we had outstanding an aggregate principal amount of  $1.0 billion of 9 3/8% senior notes. The senior notes mature on February 1, 2009. Interest on the senior notes is payable semiannually on February 1 and August 1. The senior note indenture does not contain any sinking fund or mandatory redemption requirement for the senior notes prior to maturity.

 

October 1999 Convertible Notes.  In October 1999, we issued 6.25% convertible notes due 2009 in an aggregate principal amount of $300.0 million and 2.25% convertible notes due 2009 at an issue price of $300.1 million, representing 70.52% of their principal amount at maturity of $425.5 million. The difference between the issue price and the principal amount at maturity of the 2.25% convertible notes will be accreted each year at the rate of 6.25% per annum as interest expense in our consolidated financial statements. The 6.25% convertible notes are convertible into shares of our Class A common stock at a conversion price of $24.40 per share. The 2.25% convertible notes are convertible into shares of Class A common stock at a conversion price of $24.00 per share.

 

The indentures under which the convertible notes were issued do not contain any sinking fund or mandatory redemption requirement for the convertible notes prior to maturity. However, holders may require us to repurchase all or any of their 6.25% convertible notes on October 22, 2006 at their principal amount, together with accrued and unpaid interest. Holders may require us to repurchase all or any of their 2.25% convertible notes on October 22, 2003 at $802.93, which is its issue price plus accreted original issue discount, together with accrued and unpaid interest. Based on the principal amount of the 2.25% notes outstanding as of December 31, 2002, we may be required to repurchase up to $216.7 million (accreted through October 22, 2003) principal amount of our 2.25% convertible notes on October 22, 2003, if all the holders exercise this put right.

 

We may, subject to certain conditions in the applicable indenture, elect to pay the repurchase price of each series of convertible notes in cash or shares of our Class A common stock, or any combination thereof.

 

The amended credit facilities permit us to use up to $217.0 million of escrowed cash to purchase the 2.25% convertible notes, whether pursuant to the holders’ put rights on October 22, 2003, in privately negotiated transactions, or otherwise. Notwithstanding this right, we will continue to evaluate financing opportunities with respect to our convertible notes generally and, in particular, with respect to the put right of the 2.25% convertible notes. Since we issued the convertible notes, we have successfully reduced the principal amount outstanding of these convertible notes by entering into, from time to time, a limited number of privately negotiated agreements with noteholders to induce them to convert their convertible notes into shares of our Class A common stock. As a result of such conversions, we acquired $155.6 million principal amount (face) of the 2.25% convertible notes and $87.3 million of the 6.25% convertible notes during 2000 and 2001. We may seek, from time to time, to reduce further our indebtedness through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. Such purchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. If the put option of the holders of the 2.25% convertible notes is satisfied by other means or if it is not exercised in full by the holders, we may use any remaining escrowed funds to pay, prior to June 30, 2004, any of our other convertible notes or our senior notes.

 

As of December 31, 2002, the total amounts outstanding under the 2.25% and 6.25% convertible notes were $210.9 million and $212.7 million, respectively.

February 2000 Convertible Notes.  In February 2000, we issued 5.0% convertible notes due 2010 in an aggregate principal amount of $450.0 million. The 5.0% convertible notes are convertible into shares of our Class A common stock at a conversion price of $51.50 per share. The indenture under which the 5.0% convertible notes are outstanding does not contain any sinking fund or mandatory redemption requirement for the convertible notes prior to maturity. However, holders may require us to repurchase all or any of the 5.0% convertible notes on February 20, 2007 at their principal amount, together with accrued and unpaid interest. We may, subject to certain conditions in the indenture, elect to pay the repurchase price in cash or shares of Class A common stock or any combination thereof.

 

The total amount outstanding under the 5.0% convertible notes as of December 31, 2002 was $450.0 million.

 

Other Long-Term Debt.  As of December 31, 2002, we had approximately $81.0 million of other long-term debt, including $47.2 million of capital lease obligations and $33.8 million of mortgage indebtedness and other notes payable.

 

Tower Construction and Acquisition.  As of December 31, 2002, we were party to various arrangements relating to the construction of tower sites under existing build-to-suit agreements. In addition, as of December 31, 2002, we were committed to acquire approximately 400 communication sites for an aggregate purchase price of approximately $74.0 million, of which $24.0 million had been funded as of March 4, 2003.

 

ATC Separation. In connection with the ATC Separation, we agreed to reimburse CBS for any tax liabilities incurred by American Radio as a result of the transaction. Upon completion of the final American Radio tax returns, the amount of these tax liabilities was determined and paid by us. We continue to be obligated under a tax indemnification agreement with CBS, however, until June 30, 2003, subject to the extension of federal and applicable state statutes of limitations.

 

We are currently aware that the Internal Revenue Service (IRS) is in the process of auditing certain tax returns filed by CBS and its predecessors, including those that relate to American Radio and the ATC Separation transaction. In the event that the IRS imposes additional tax liabilities on American Radio relating to the ATC Separation, we would be obligated to reimburse CBS for such liabilities. We cannot currently anticipate or estimate the potential additional tax liabilities, if any, that may be imposed by the IRS, however, such amounts could be material to our consolidated financial position and results of operations. We are not aware of any material obligations relating to this tax indemnity as of December 31, 2002. Accordingly, no amounts have been provided for in the consolidated financial statements relating to this indemnification.

*   The holders of our convertible notes have the right to require us to repurchase their notes on specified dates prior to their maturity dates in 2009 and 2010, but we may pay the purchase price by issuing shares of our Class A common stock, subject to certain conditions discussed elsewhere in this annual report. The obligation with respect to the right of the holders to put the 2.25% convertible notes on October 22, 2003 of approximately $210.9 million as of December 31, 2002 has been classified as an obligation due in “Less than 1 year”. The obligations with respect to the right of the holders to put the 6.25% convertible notes ($212.7 million) and 5% notes  ($450.0 million) on October 22, 2006 and February 20, 2007, respectively, have been classified as an obligation due in “3-5 years” as of December 31, 2002.

Table of Contents

 

The above table does not include approximately $116.9 million of aggregate principal payments for Verestar capital leases that are included in liabilities held for sale as of December 31, 2002 and financial guarantees of up to $12.0 million that we may be obligated to pay in connection with certain Verestar contractual obligations. Such amounts have been excluded from the table as we expect to sell the remaining portion of Verestar by December 31, 2003. The above table also excludes certain commitments relating to the construction of tower sites under existing build to suit agreements as of December 31, 2002, as we cannot currently estimate the timing and amounts of such payments.

 

Factors Affecting Sources of Liquidity

 

Internally Generated Funds.  The key factors affecting our internally generated funds are the demand for antennae space on wireless communications towers and for related services, our ability to maximize the utilization of our existing towers and our ability to minimize costs and fully achieve our operating efficiencies.

 

Credit Facilities.   Our credit facilities, as amended in February 2003, contain certain financial ratios and operational covenants and other restrictions (including limitations on additional debt, guarantees, dividends and other distributions, investments and liens) with which our borrower subsidiaries and restricted subsidiaries must comply. Any failure to comply with these covenants would not only prevent us from being able to borrow additional funds under our revolving line of credit, but would also constitute a default. These covenants also restrict our ability, as the parent, to incur any debt other than that presently outstanding and refinancings of that debt. Our credit facilities, as amended, contain five financial tests:

 

    a leverage ratio (Total Debt to Annualized Operating Cash Flow). As of December 31, 2002, we were required to maintain a ratio of not greater than 6.00 to 1.00, increasing to 6.25 to 1.00 at January 1, 2003, decreasing to 6.00 to 1.00 at July 1, 2003, to 5.75 to 1.00 at October 1, 2003, to 5.50 to 1.00 at January 1, 2004, to 5.25 to 1.00 at April 1, 2004, to 5.00 to 1.00 at July 1, 2004, to 4.75 to 1.00 at October 1, 2004, to 4.50 to 1.00 at January 1, 2005, to 4.25 to 1.00 at April 1, 2005 and to 4.00 to 1.00 at July 1, 2005 and thereafter;

 

    a senior leverage ratio (Senior Debt to Annualized Operating Cash Flow). As of January 1, 2003, we were required to maintain a ratio of not greater than 4.90 to 1.00, decreasing to 4.75 to 1.00 at April 1, 2003, to 4.50 to 1.00 at July 1, 2003, to 4.25 to 1.00 at October 1, 2003, to 4.00 to 1.00 at January 1, 2004, to 3.75 to 1.00 at April 1, 2004, to 3.50 to 1.00 at July 1, 2004, to 3.25 to 1.00 at October 1, 2004 and to 3.00 to 1.00 at January 1, 2005 and thereafter;

 

    a pro forma debt service test (Annualized Operating Cash Flow to Pro Forma Debt Service). As of December 31, 2002, we were required to maintain a ratio of not less than 1.00 to 1.00;

 

    an interest coverage test (Annualized Operating Cash Flow to Interest Expense). As of December 31, 2002, we were required to maintain a ratio of not less than 2.00 to 1.00, increasing by 0.50 on each of January 1, 2003 and January 1, 2004; and

 

    a fixed charge coverage test (Annualized Operating Cash Flow to Fixed Charges). As of December 31, 2003, we will be required to maintain a ratio of not less than 1.0 to 1.0.

 

The amended credit facilities also limit our revolving loan drawdowns based on our cash on hand.

 

Because the credit facilities are with certain of our subsidiaries, including ATI, our senior notes and convertible notes are not included in the computations of any of the tests, except in the case of the pro forma debt service and fixed charge coverage tests in which case interest includes the amount of funds that we need our subsidiaries to distribute to us so we can pay interest on our senior notes and our convertible notes. Annualized Operating Cash Flow is based, among other things, on four times the Operating Cash Flow for the most recent quarter of our tower rental and management business and trailing 12 months for our other businesses and for corporate general and administrative expenses. In the case of the leverage ratio, we may include the Operating Cash Flow from Brazil and Mexico only to the extent of 10% of Annualized Operating Cash Flow and we receive credit for only 75% of Annualized Operating Cash Flow from our services businesses.

Table of Contents

 

We were in compliance with the borrowing ratio covenants in effect as of December 31, 2002, and as amended by the February 2003 amendment.

 

9 3/8% Senior Note Indenture.   The senior note indenture contains certain restrictive covenants with which we and our restricted subsidiaries (which includes all of our subsidiaries other than Verestar and its subsidiaries) must comply. These include restrictions on our ability to incur additional debt, guarantee debt, pay dividends and make other distributions, make certain investments and, as in the credit facilities, use the proceeds from asset sales. Any failure to comply with these covenants would not only prevent us from being able to borrow additional funds, but would also constitute a default. Specifically, the senior note indenture restricts us from incurring additional debt or issuing certain types of preferred stock unless our consolidated debt (which excludes debt of Verestar and its subsidiaries but includes the liquidation value of certain preferred stock) is not greater than 7.5 times our Adjusted Consolidated Cash Flow. However, we are permitted, even if we are not in compliance with the ratio, to incur debt under our credit facilities, or renewals, refundings, replacements or refinancings of them, up to $2.65 billion. Even if not in compliance with the ratio, we are also permitted to, among other things, have certain types of capital leases and to refund or refinance our convertible notes, subject to certain requirements. Adjusted Consolidated Cash Flow is substantially similar to the definition of Annualized Operating Cash Flow, as defined in the credit facilities, except it applies to us and our subsidiaries (other than Verestar and its subsidiaries).

 

12.25% Discount Notes.   The discount note indenture contains certain restrictive covenants with which ATI, the sister guarantors and its and their subsidiaries must comply. These include restrictions on the ability to incur additional debt, guarantee debt, pay dividends and make other distributions, make certain investments and, as in the credit facilities, use the proceeds from asset sales. Any failure to comply with these covenants would not only prevent us from being able to borrow additional funds, but would also constitute a default. Specifically, the discount note indenture restricts ATI, each of the sister guarantors and its and their restricted subsidiaries from incurring additional debt or issuing certain types of preferred stock. However, ATI, the sister guarantors and its and their subsidiaries are permitted to incur debt under our credit facilities, or renewals, refundings, replacements or refinancings of them, up to $1.6 billion. They are also permitted, among other things, to have certain types of capital leases and to refund or refinance existing indebtedness, subject to certain requirements.

 

Convertible Notes.    The indentures under which our convertible notes are outstanding do not contain any restrictions on, among other things, the payment of dividends or the making of other distributions, the incurrence of debt, or liens or the repurchase of our equity securities, or any financial covenants.

 

Capital Markets.  Our ability to raise additional funds in the capital markets depends on, among other things, general economic conditions, the condition of the wireless industry, our financial performance and the state of the capital markets.

 

Critical Accounting Policies

 

In December 2001, the SEC requested that all registrants disclose their most “critical accounting policies” in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” The SEC indicated that a “critical accounting policy” is one which is both important to the portrayal of the company’s financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Further, “critical accounting policies” are those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions.

 

We believe that our accounting policies described below fit the definition of “critical accounting policies.” We reviewed our policies for the year ended December 31, 2002 and determined that they remain our most critical accounting policies. With the exception of the asset impairment charges and the adoption of SFAS No. 142, we did not make any changes to those policies during the year ended December 31, 2002.

    Income Taxes.   We record a valuation allowance to reduce our net deferred tax asset to the amount that management believes is more likely than not to be realized. At December 31, 2002, we provided a valuation allowance of approximately $118.6 million primarily related to our state operating loss carryforwards and capital loss carryforwards. In addition, we also recorded a valuation allowance in 2002 related to implementing a tax planning strategy to accelerate the utilization of certain federal net operating losses (the valuation allowance represents the estimated lost tax benefit and costs associated with implementing this strategy). We have not provided a valuation allowance for the remaining deferred tax assets, primarily our federal net operating loss carryforwards as management believes that we will have sufficient time to realize these assets during the carryforward period.

 

We intend to recover a portion of our net deferred tax asset from our tax planning strategy to accelerate the utilization of certain federal net operating losses. The recoverability of our remaining net deferred tax asset has been assessed utilizing stable state (no growth) projections based on our current operations. The projections show a significant decrease in depreciation and interest expense in the later years of the carryforward period as a result of a significant portion of our assets being fully depreciated during the first fifteen years of the carryforward period and debt repayments reducing interest expense. Accordingly, the recoverability of our net deferred tax asset is not dependent on material improvements to operations, material asset sales or other non-routine transactions. Based on our current outlook of future taxable income during the carryforward period, management believes that our net deferred tax asset will be realized. The realization of our deferred tax assets will be dependent upon our ability to generate approximately $800.0 million in taxable income from January 1, 2003 to December 31, 2022. If we are unable to generate sufficient taxable income in the future, or accelerate the utilization of our losses as contemplated in our tax planning strategy, we will be required to reduce our net deferred tax asset through a charge to income tax expense, which would result in a corresponding decrease in stockholders equity.

 

    Impairment of Assets.

 

Assets subject to amortization and non-core assets held for sale:    We review long-lived assets, including intangibles, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We assess recoverability by determining whether the net book value of the related assets will be recovered through projected undiscounted cash flows. If we determine that the carrying value of an asset may not be recoverable, we will measure any impairment based on the projected future discounted cash flows to be provided from the asset or available market information relative to the asset’s fair market value as compared to its carrying value. We record any related impairment losses in the period in which we identify such impairment. We also review the carrying value of assets held for sale for impairment based management’s best estimate of the anticipated net proceeds expected to be received upon final disposition. We record any impairment charges or estimated losses on disposal in the period in which we identify such impairment or loss.

 

Goodwill—Assets not subject to amortization:    As of January 1, 2002, we adopted the provisions of SFAS No. 142 “Goodwill and Other Intangible Assets,” which requires that goodwill and intangible assets with indefinite lives no longer be amortized, but reviewed for impairment at least annually. SFAS No. 142 also requires that we assess whether goodwill is impaired by performing a transitional impairment test. The impairment test is comprised of two steps. The initial step is designed to identify potential goodwill impairment by comparing an estimate of fair value of the applicable reporting unit to its carrying value, including goodwill. If the carrying value exceeds fair value, a second step is performed, which compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill to measure the amount of goodwill impairment, if any. Fair value estimates were determined based on independent third party appraisals for the rental and management segment and former SFNA segment and future discounted cash flows and market information in the services segment.

Table of Contents

 

We completed our transitional impairment testing in the second quarter of 2002 and concluded that all of the goodwill related to our former SFNA segment was impaired and that the majority of the goodwill in the services segment was impaired. As a result, we recognized a $562.6 million non-cash charge (net of a tax benefit of $14.4 million) related to the write-down of goodwill to its fair value. In accordance with the provisions of SFAS No. 142, the charge is reflected as of January 1, 2002 and included in the results of operations for the year ended December 31, 2002 as the cumulative effect of a change in accounting principle.

 

We also completed our annual impairment testing in December 2002 related to the goodwill of the tower rental and management reporting unit that contains goodwill and Kline (the only services business with remaining goodwill) and determined that goodwill was not impaired. We obtained an independent third party appraisal of the tower and rental management reporting unit that contains goodwill and utilized market information to value Kline.

 

We will perform our annual goodwill impairment test in December of each year and when events or circumstances indicate that the asset might be impaired.

 

    Investment Impairment Charges.  Investments in those entities where we own less than twenty percent of the voting stock of the individual entity and do not exercise significant influence over operating and financial policies of the entity are accounted for using the cost method. Investments in entities where we own less than twenty percent but have the ability to exercise significant influence over operating and financial policies of the entity or where we own more than twenty percent of the voting stock of the individual entity, but not in excess of fifty percent, are accounted for using the equity method. Our investments are in companies that are not publicly traded, and, therefore, no established market for these securities exists. We have a policy in place to review the fair value of our investments on a regular basis to evaluate the carrying value of the investments in these companies. If we believe that the carrying value of an investment is carried at an amount in excess of fair value, it is our policy to record an impairment charge to adjust the carrying value to the market value.

 

    Revenue Recognition.  A portion of our network development services revenue is derived under contracts or arrangements with customers that provide for billings on a fixed price basis. Revenues under these contracts are recognized using the percentage-of-completion methodology. Under the percentage-of-completion methodology, revenues are recognized in accordance with the percentage of contract costs incurred to date compared to the estimated total contract costs. Due to uncertainties and estimates inherent within percentage-of-completion accounting it is possible that estimates will be revised as project work progresses. Changes to total estimated contract costs or losses, if any, are recognized in the period in which they are determined.

 

The above listing is not intended to be a comprehensive list of all of our accounting policies. See our audited consolidated financial statements and notes thereto which begin on page F-1 of this annual report where our significant accounting policies are discussed.

 

Recent Accounting Pronouncements

 

In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” This statement establishes accounting standards for the recognition and measurement of liabilities associated with the retirement of tangible long-lived assets and the related asset retirement costs. The requirements of SFAS No. 143 are effective for us as of January 1, 2003. We will adopt this statement in the first quarter of 2003 and do not expect the impact of adopting this statement to have a material impact on our consolidated financial position or results of operations.

Table of Contents

 

In April 2002, the FASB issued SFAS No. 145 “Rescission of FASB Statement Nos. 4, 44, and 64, Amendment of FASB Statement No. 13 and Technical Corrections.” Upon the adoption of SFAS No. 145, gains and losses from extinguishment of debt will no longer be classified as an extraordinary item, but rather will generally be classified as part of other income (expense) on our consolidated statement of operations. Any such gains or losses classified as extraordinary items in prior periods will be reclassified in future financial statement presentations upon the adoption of SFAS No. 145. We will adopt the provisions of SFAS No. 145 for all reporting periods subsequent to January 1, 2003.

 

In July 2002, the FASB issued SFAS No. 146 “Accounting For Costs Associated with Exit or Disposal Activities.” The statement requires costs associated with exit or disposal activities to be recognized when they are incurred rather than at the date of the commitment to an exit or disposal plan. The requirements of SFAS No. 146 are effective for exit or disposal activities initiated after January 1, 2003. We will apply the provisions of this statement to all restructuring activity initiated after January 1, 2003.

 

In December 2002, the FASB issued SFAS No. 148, “Accounting for Stock-Based Compensation- Transition and Disclosure—an amendment of SFAS No. 123,” which provides optional transition guidance for those companies electing to voluntarily adopt the accounting provisions of SFAS No. 123. In addition, the statement mandates certain new disclosures that are incremental to those required by SFAS No. 123. We will continue to account for stock-based compensation in accordance with APB No. 25. As such, we do not expect this standard to have a material impact on our consolidated financial position or results of operations. We have adopted the disclosure-only provisions of SFAS No. 148 as of December 31, 2002. (See note 1 to our consolidated financial statements).

 

In January 2003, the FASB issued Interpretation No. 46, “Consolidation for Variable Interest Entities, an Interpretation of ARB No. 51” which requires all variable interest entities (VIEs) to be consolidated by the primary beneficiary. The primary beneficiary is the entity that holds the majority of the beneficial interest in the VIE. In addition, the interpretation expands the disclosure requirements for both variable interest entities that are consolidated as well as VIEs from which the entity is the holder of a significant amount of beneficial interests, but not the majority. FIN 46 is effective for all VIE’s created or acquired after January 31, 2003. For VIE’s created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003. The adoption of this interpretation is not expected to be material to our consolidated financial position or results of operations.

ITEM   7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

 

We are exposed to market risk from changes in interest rates on long-term debt obligations. We attempt to reduce these risks by utilizing derivative financial instruments, namely interest rate caps, swaps, and collars pursuant to our policies. All derivative financial instruments are for purposes other than trading. For the year ended December 31, 2002, we increased our borrowings under our credit facilities by $65.0 million. We also terminated two swaps with aggregate notional amounts totaling $150.0 million and caps with total notional amounts of $365.0 million expired. In addition, swaps with total notional amounts of $30.0 million and a collar with a total notional amount of $95.0 million expired. Lastly, we entered into four cap agreements with total notional amounts of $500.0 million.

 

The following tables provide information as of December 31, 2002 and 2001 about our market risk exposure associated with changing interest rates. For long-term debt obligations, the tables present principal cash flows by maturity date and average interest rates related to outstanding obligations. For interest rate caps, swaps and collars, the tables present notional principal amounts and weighted-average interest rates by contractual maturity dates.

The average interest rate in effect at December 31, 2001 for the credit facilities was 4.76%. For the year ended December 31, 2001, the weighted average interest rate under the credit facilities was 7.26%. The 2.25% and 6.25% convertible notes each bear interest (after giving effect to the accretion of the original discount on the 2.25% convertible notes) at 6.25% per annum, which is payable semiannually on April 15 and October 15 of each year. The 5.0% convertible notes bear interest at 5.0% per annum, which is payable semiannually on February 15 and August 15 of each year.

We maintain a portion of our cash and cash equivalents in short-term financial instruments that are subject to interest rate risks. Due to the relatively short duration of such instruments, we believe fluctuations in interest rates with respect to those investments will not materially affect our financial condition or results of operations.

 

Our foreign operations, which primarily include Mexico, have not been significant to date. The remeasurement loss (gain) for the years ended December 31, 2002, 2001 and 2000 approximated $3,713,000, $(207,000) and 11,000, respectively.

INDEPENDENT AUDITORS’ REPORT

 

To the Board of Directors of

American Tower Corporation:

 

We have audited the accompanying consolidated balance sheets of American Tower Corporation and subsidiaries (the “Company”) as of December 31, 2002 and 2001, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2002. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

 

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

 

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2002 and 2001, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2002 in conformity with accounting principles generally accepted in the United States of America.

 

As discussed in notes 1 and 8 to the consolidated financial statements, in 2001 the Company adopted the provisions of Statement of Financial Accounting Standard No. 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended. Also, as discussed in notes 1 and 5 to the consolidated financial statements, in 2002 the Company adopted Statement of Financial Accounting Standard No. 142, “Goodwill and Other Intangible Assets.”

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 

1.    BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 

Business—American Tower Corporation and subsidiaries (collectively, ATC or the Company), is an independent owner, operator and developer of wireless and broadcast communications sites in the United States, Mexico and Brazil. The Company’s primary business, as discussed in note 16, is the leasing of antenna space on multi-tenant communications towers to wireless service providers and radio and television broadcast companies. The Company also provides network development services to wireless service providers and broadcasters.

 

In December 2002, the Company committed to a plan to dispose of (by sale) its wholly owned subsidiary, Verestar, Inc., (Verestar) within the next twelve months. Verestar provides satellite and fiber network access services (SFNA) to telecommunications companies, internet service providers, governmental organizations, broadcasters and maritime customers worldwide. The operations of Verestar previously comprised the Company’s entire satellite and fiber network access services segment, which is no longer reported as a separate segment, as it is included in discontinued operations. During 2002, the Company also sold or committed to sell additional non-core businesses which are also reported as discontinued operations. (See note 2).

 

Principles of Consolidation and Basis of Presentation—The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated. The Company consolidates those entities in which it owns greater than fifty percent of the entity’s voting stock.

 

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying consolidated financial statements. The significant estimates in the accompanying consolidated financial statements include revenue recognition under the percentage of completion method, impairment of cost and equity investments, impairment of long-lived assets (including goodwill) and valuation allowances related to deferred tax assets.

 

Revenue Recognition—Rental and management revenues are recognized on a monthly basis under lease or management agreements when earned. Escalation clauses, excluding those tied to the Consumer Price Index (CPI), and other incentives present in lease agreements with the Company’s customers are recognized on a straight-line basis over the term of the lease. Amounts billed or received prior to being earned are deferred until such time as the earnings process is complete.

 

Network development service revenues are derived under contracts or arrangements with customers that provide for billings on a time and materials, cost plus profit or fixed price basis. Revenues are recognized as services are performed with respect to the time and materials and cost plus profit contracts. Revenues are recognized using the percentage-of-completion method for fixed price contracts. Under the percentage-of-completion methodology, revenues are recognized in accordance with the percentage of contract costs incurred to date compared to estimated total contract costs. Costs and earnings in excess of billings on uncompleted contracts represent revenues recognized in excess of amounts billed. Billings in excess of costs and earnings on uncompleted contracts represent billings in excess of revenues recognized. Changes to total estimated contract costs or losses, if any, are recognized in the period in which they are determined.

 

Development Expense—Development expense consists of uncapitalized acquisition costs, costs to integrate acquisitions, costs associated with new business initiatives, abandoned acquisition costs and costs associated with tower site inspections and related data gathering. Such costs are expensed as incurred.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

 

Corporate General and Administrative Expense—Corporate general and administrative expense consists of corporate overhead costs not specifically allocable to any of the Company’s individual business segments.

 

Note Conversion Expense—Note conversion expense represents the fair value of incremental stock issued to induce convertible noteholders to convert their holdings prior to the first scheduled redemption date. Such amounts were expensed as incurred in accordance with Statement of Financial Accounting Standard (SFAS) No. 84 “Induced Conversions of Convertible Debt.” (See note 7).

 

Concentrations of Credit Risk—Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents, notes receivable, trade receivables and derivative instruments. The Company mitigates its risk with respect to cash and cash equivalents and derivative instruments by maintaining its deposits and contracts at high quality financial institutions and monitoring the credit ratings of those institutions.

 

The Company mitigates its concentrations of credit risk with respect to notes and trade receivables by actively monitoring the credit worthiness of its borrowers and customers. Accounts receivable are reported net of allowances for doubtful accounts of $17,437,000, $23,804,000 and $19,809,000 as of December 31, 2002, 2001 and 2000, respectively. Net amounts charged against the allowance for doubtful accounts for the years ended December 31, 2002, 2001 and 2000 approximated $18,299,000, $7,137,000 and $1,697,000, respectively. Bad debt recoveries for the years ended December 31, 2002, 2001 and 2000 are $1,097,000, $978,000 and $1,238,000, respectively. The effect of discontinued operations on the allowance for doubtful accounts for the years ended December 31, 2002, 2001 and 2000 approximated $(4,840,000), $(4,903,000) and $9,234,000, respectively

 

Discount on Convertible Notes—The Company amortizes the discount on its convertible notes using the effective interest method over the term of the obligation. Such amortization is recorded as interest expense in the accompanying consolidated statements of operations.

 

Derivative Financial Instruments—On January 1, 2001, the Company adopted the provisions of SFAS No. 133 “Accounting for Derivative Instruments and Hedging Activities,” as amended. This statement establishes accounting and reporting standards for derivative instruments. Specifically, it requires that an entity recognize all derivatives as either assets or liabilities on the balance sheet at fair value. The accounting for changes in the fair market value of a derivative (that is unrealized gains or losses) is recorded as a component of an entity’s net income or other comprehensive income, depending upon designation and qualification as part of a hedging relationship. The cumulative effect of adopting this statement resulted in a charge to other comprehensive loss of $7.9 million (net of a tax benefit of $4.2 million) as of January 1, 2001. The 2002 and 2001 consolidated financial statements were prepared in accordance with the provisions of SFAS No. 133 and the 2000 consolidated financial statements were prepared in accordance with the applicable professional literature for derivatives and hedging instruments in effect at that time.

 

The Company is exposed to interest rate risk relating to variable interest rates on its credit facilities. As part of its overall strategy to manage the level of exposure to the risk of interest rate fluctuations under its variable rate credit facilities, the Company uses interest rate swaps, caps and collars, which qualify and are designated as cash flow hedges. In 2001, the Company also used swaptions to manage interest rate risk, which were not designated as cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative instrument is initially reported as a component of other comprehensive loss and subsequently reclassified into the statement of operations when the hedged transaction affects operations. The ineffective portion of the gain or loss on the derivative instrument is immediately recognized in the statement of operations. For derivative instruments not designated as hedging instruments, the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

gain or loss is recognized in the statement of operations in the period of change. The Company does not hold derivative financial instruments for trading purposes. (See note 8).

 

Foreign Currency Translation—The Company’s foreign subsidiaries in Mexico and Brazil have designated the U.S. dollar as their functional currency. Monetary assets and liabilities related to the Company’s Mexican and Brazilian operations are remeasured from the local currency into U.S. dollars at the rate of currency exchange at the end of the applicable fiscal period. Non-monetary assets and liabilities are remeasured at historical exchange rates. Revenues and expenses are remeasured at average monthly exchange rates. All remeasurement gains and losses are included in the Company’s consolidated statement of operations within the caption loss on investments and other expense. The remeasurement loss (gain) for the years ended December 31, 2002, 2001 and 2000 approximated $3,713,000, $(207,000) and $11,000, respectively.

 

The Company’s Verestar subsidiary, classified within discontinued operations, maintains a teleport business in Switzerland and has designated the Swiss franc as its functional currency. Accordingly, assets and liabilities are translated from the Swiss franc into U.S. dollars at the end of period exchange rate, and revenues and expenses are translated at average monthly exchange rates. Translation gains and losses are recorded in stockholders’ equity and reflected as a component of other comprehensive loss.

 

Cash and Cash Equivalents—Cash and cash equivalents include cash on hand, demand deposits and short-term investments with remaining maturities (when purchased) of three months or less.

 

Restricted Cash—As of December 31, 2001, restricted cash represented amounts required to be held in escrow under the Company’s credit facilities to pay interest on its convertible and senior note obligations. The restrictions related to these funds expired in August 2002.

 

Inventories—Inventories, which consist primarily of finished goods and raw material component parts, are stated at the lower of cost or market, with cost being determined on the first-in, first-out (FIFO) basis. The components of inventories as of December 31, 2002 and 2001 are as follows (in thousands):

Property and Equipment—Property and equipment are recorded at cost or at estimated fair value (in the case of acquired properties). Cost for self-constructed towers includes direct materials and labor, indirect costs associated with construction and capitalized interest. Approximately $5,835,000, $15,321,000 and $11,365,000 of interest was capitalized for the years ended December 31, 2002, 2001 and 2000, respectively.

 

Depreciation is provided using the straight-line method over the assets’ estimated useful lives. Property and equipment acquired through capitalized leases are amortized using the straight-line method over the shorter of the lease term or the estimated useful life of the asset. Asset useful lives are as follows:

 

Equipment

  

3-15 years

Towers

  

15 years

Buildings

  

32 years

Building and land improvements

  

15-32 years

 

Expenditures for repairs and maintenance are expensed as incurred. Betterments and improvements that extend an asset’s useful life or enhance capacity are capitalized.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

 

Goodwill and Other Intangible Assets—In June 2001, the Financial Accounting Standards Board (FASB) issued SFAS No. 141, “Business Combinations” and SFAS No. 142, “Goodwill and Other Intangible Assets.” SFAS No. 141 eliminates the pooling-of-interests method of accounting for business combinations. SFAS No. 141 also includes enhanced criteria for identifying intangible assets separately from goodwill. The requirements of SFAS No. 141 were effective for any business combination consummated by the Company subsequent to June 30, 2001. The Company did not consummate any transactions subsequent to June 30, 2001 that gave rise to goodwill. As of January 1, 2002, the Company adopted the provisions of SFAS No. 142 “Goodwill and Other Intangible Assets.” SFAS No. 142 requires that goodwill and intangible assets with indefinite lives no longer be amortized, but reviewed for impairment at least annually. Intangible assets that are deemed to have a definite life will continue to be amortized over their useful lives. The adoption of this statement reduced the Company’s amortization expense (including that related to discontinued operations) by approximately $96.0 million for the year ended December 31, 2002. (See note 5).

 

Income TaxesThe consolidated financial statements reflect provisions for federal, state, local and foreign income taxes. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as operating loss and tax credit carryforwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company provides valuation allowances if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. (See note 12).

 

Loss Per Common Share—Basic and diluted net loss per common share has been computed by dividing the Company’s net loss by the weighted average number of common shares outstanding during the period. For the years ended December 31, 2002, 2001 and 2000, potential common shares, including options, warrants and shares issuable upon conversion of the Company’s convertible notes, have been excluded from the computation of diluted loss per common share, as their effect is anti-dilutive. Potential common shares excluded from the calculation of net loss per share were approximately 50.6 million, 46.4 million and 52.4 million for the years ended December 31, 2002, 2001 and 2000, respectively.

 

Impairments and Net Loss on Sale of Long-Lived Assets—The Company reviews long-lived assets, including intangibles with definite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses recoverability by determining whether the net book value of the related assets will be recovered through projected undiscounted future cash flows. If the Company determines that the carrying value on an asset may not be recoverable, it measures any impairment based on the projected future discounted cash flows or estimated sale proceeds to be provided from the asset as compared to its carrying value. The Company records impairment losses in the period in which it identifies such impairment.

 

During the years ended December 31, 2002 and 2001, the Company recorded impairments and net loss on sale of long-lived assets within its rental and management segment of $90.7 million and $74.3 million, respectively. The significant components of these charges and net losses include the following:

 

Non-Core Tower Asset Impairment Charges—During the year ended December 31, 2002, the Company sold approximately 720 non-core towers and recorded impairment charges to write-down certain other non-core towers. As a result, the Company recorded impairment charges and net losses of approximately $46.8 million for the year ended December 31, 2002.

 

 

F-10


Table of Contents

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

During the year ended December 31, 2001, the Company recorded impairment charges of approximately $11.7 million to write-down certain non-core towers.

 

Construction-In-Progress Impairment Charges—In September 2002, the Company reduced the scope of its new tower construction and build plans for the remainder of 2002 and for 2003 by implementing more stringent construction criteria than was previously in place. As a result, the Company wrote off approximately $40.2 million of construction-in-progress costs associated with approximately 800 sites that it no longer plans to build.

 

In November 2001, the Company announced certain initiatives that included a reduction in the scope of its tower development activities. This resulted in a significant decrease in new tower construction and more stringent criteria for evaluating tower construction and acquisitions. As a result, in the fourth quarter of 2001, the Company wrote off approximately $62.6 million of construction-in-progress costs associated with sites that it no longer intended to build.

 

Investments—Investments in those entities where the Company owns less than twenty percent of the voting stock of the individual entity and does not exercise significant influence over operating and financial policies of the entity are accounted for using the cost method. Investments in entities where the Company owns less than twenty percent but has the ability to exercise significant influence over operating and financial policies of the entity or where the Company owns more than twenty percent of the voting stock of the individual entity, but not in excess of fifty percent, are accounted for using the equity method. As of December 31, 2002 and 2001, the Company’s investments were in companies that are not publicly traded, and, therefore, no established market for their securities exists. The Company has a policy in place to review the fair value of its investments on a regular basis to evaluate the carrying value of the investments in these companies. If the Company believes that the carrying value of an investment is in excess of fair market value, it is the Company’s policy to record an impairment charge to adjust the carrying value to fair market value.

 

During the years ended December 31, 2002 and 2001, the Company recorded impairment charges on its cost and equity investments of approximately $11.3 million and $27.7 million, respectively. In addition, during the years ended December 31, 2002, 2001 and 2000, the Company recorded losses on equity method investments of approximately $9.0 million, $9.1 million and $2.5 million, respectively. Losses on equity method investments are recorded in accordance with Emerging Issues Task Force No. 99-10 “Percentage Used to Determine the Amount of Equity Method Losses.”

 

As of December 31, 2002 and 2001, the Company had cost and equity investments included in deposits, investments and other long-term assets of $32.0 million and $41.8 million, respectively.

 

Stock-Based Compensation—Pursuant to SFAS No. 123, “Accounting for Stock-Based Compensation,” the Company applies the recognition and measurement principles of Accounting Principles Board (APB) No. 25, “Accounting for Stock Issued to Employees,” to its equity grants and awards to employees officers and directors. The Company’s stock option plans are more fully described in note 13.

 

In accordance with APB No. 25, compensation expense for stock options is recognized in income based on the excess, if any, of the quoted market price of the stock at the grant date of the award or other measurement date over the amount an employee must pay to acquire the stock. To date, the Company has not issued any stock options that would result in compensation expense under the provisions of APB No. 25. Accordingly, there is no recognition of compensation expense related to option grants reflected in the accompanying consolidated statements of operations.

Fair Value of Financial Instruments—As of December 31, 2002, the carrying amounts of the Company’s 5.0% convertible notes, the 2.25% convertible notes, the 6.25% convertible notes and the senior notes were approximately $450.0 million, $210.9 million, $212.7 million and $1.0 billion, respectively, and the fair values of such notes were $291.4 million, $187.2 million, $144.4 million and $780.0 million, respectively. As of December 31, 2001, the carrying amount of the Company’s 5.0% convertible notes, the 2.25% convertible notes, the 6.25% convertible notes and the senior notes were approximately $450.0 million, $204.1 million, $212.8 million and $1.0 billion, respectively, and the fair values of such notes were $268.3 million, $173.1 million, $158.2 million and $805.0 million, respectively. Fair values were determined based on quoted market prices. The carrying values of all other financial instruments reasonably approximate the related fair values as of December 31, 2002 and 2001.

 

Retirement Plan—The Company has a 401(k) plan covering substantially all employees who meet certain age and employment requirements. Under the plan, the Company matches 35% of participants’ contributions up to a maximum 5% of a participant’s compensation. The Company contributed approximately $979,000, $1,540,000 and $1,593,000 to the plan for the years ended December 31, 2002, 2001 and 2000, respectively.

 

Recent Accounting Pronouncements—In June 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations.” This statement establishes accounting standards for the recognition and measurement of liabilities associated with the retirement of tangible long-lived assets and the related asset retirement costs. The requirements of SFAS No. 143 are effective for the Company as of January 1, 2003. The Company will adopt this statement in the first quarter of 2003 and does not expect the impact of adopting this statement to have a material impact on its consolidated financial position or results of operations.

 

In August 2001, the FASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” SFAS No. 144 supersedes SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,” but retains many of its fundamental provisions. SFAS No. 144 also clarifies certain measurement and classification issues from SFAS No. 121. In addition, SFAS No. 144 supersedes the accounting and reporting provisions for the disposal of a business segment as found in APB  No. 30, “Reporting the Results of Operations—Reporting the Effects of Disposal of a Segment of a Business and Extraordinary, Unusual and Infrequently Occurring Events and Transactions”. However, SFAS No. 144 retains the requirement in APB No. 30 to separately report discontinued operations, and broadens the scope of such requirement to include more types of disposal transactions. The scope of SFAS No. 144 excludes goodwill and other intangible assets that are not to be amortized, as the accounting for such items is prescribed by SFAS No. 142. The Company implemented SFAS No. 144 on January 1, 2002. Accordingly, all relevant impairment assessments and decisions concerning discontinued operations have been made under this standard in 2002.

In April 2002, the FASB issued SFAS No. 145 “Rescission of FASB Statement Nos. 4, 44, and 64, Amendment of FASB Statement No. 13 and Technical Corrections.” Upon adoption of SFAS No. 145, gains and losses from extinguishment of debt will no longer be classified as extraordinary items, but rather will be classified as part of other income (expense) on the Company’s consolidated statement of operations. Any such gains or losses classified as extraordinary items in prior periods will be reclassified in future financial statement presentations upon the adoption of SFAS No. 145. The Company will adopt the provisions of SFAS No. 145 for all reporting periods subsequent to January 1, 2003.

 

In July 2002, the FASB issued SFAS No. 146 “Accounting For Costs Associated with Exit or Disposal Activities.” The statement requires costs associated with exit or disposal activities to be recognized when they are incurred rather than at the date of a commitment to an exit or disposal plan. The requirements of SFAS  No. 146 are effective for exit or disposal activities initiated after January 1, 2003. The Company will apply the provisions of this statement to all restructuring activity initiated after January 1, 2003.

 

In December 2002, the FASB issued SFAS No. 148, “Accounting for Stock-Based Compensation-Transition and Disclosure—an amendment of SFAS No. 123,” which provides optional transition guidance for those companies electing to voluntarily adopt the accounting provisions of SFAS No. 123. In addition, the statement mandates certain new disclosures that are incremental to those required by SFAS No. 123. The Company will continue to account for stock-based compensation in accordance with APB No. 25. As such, the Company does not expect this standard to have a material impact on its consolidated financial position or results of operations. The Company has adopted the disclosure-only provisions of SFAS No. 148 as of December 31, 2002.

 

In January 2003, the FASB issued Interpretation No. 46, “Consolidation for Variable Interest Entities, an Interpretation of ARB No. 51” which requires all variable interest entities (VIEs) to be consolidated by the primary beneficiary. The primary beneficiary is the entity that holds the majority of the beneficial interest in the VIE. In addition, the interpretation expands the disclosure requirements for both variable interest entities that are consolidated as well as VIEs from which the entity is the holder of a significant amount of beneficial interests, but not the majority. FIN 46 is effective for all new VIEs created or acquired after January 31, 2003. For VIEs created or acquired prior to February 1, 2003, the provisions of FIN 46 must be applied for the first interim or annual period beginning after June 15, 2003. The adoption of this interpretation is not expected to be material to the Company’s consolidated financial position or results of operations.

 

Reclassifications—Certain reclassifications have been made to the 2001 and 2000 financial statements to conform with the 2002 presentation.

 

2.    DISCONTINUED OPERATIONS

 

In 2002, in connection with the Company’s plan to focus on its core tower business, the Company sold or committed to sell several non-core businesses. In accordance with SFAS No. 144, the Company classified the operating results of these businesses as discontinued operations in the accompanying statements of operations. In addition, the assets and liabilities of the discontinued operations not disposed of as of December 31, 2002 have been reflected as assets held for sale and liabilities held for sale in the accompanying consolidated balance sheet as of December 31, 2002. The effect of suspending depreciation and amortization for the long-lived assets held for sale was not material for the year ended December 31, 2002.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

 

The following businesses have been reflected as discontinued operations in the accompanying statements of operations for all periods presented.

 

In July 2002, the Company consummated the sale of MTS Components (previously included in the network development services segment) and incurred a loss on disposal of approximately $16.0 million (net of an income tax benefit of $8.6 million). Proceeds from the sale were approximately $32.0 million and consisted of approximately $20.0 million in cash and $12.0 million of notes receivable. The notes are comprised of a $5.6 million, secured by the working capital of the sold operations payable through January 2003; and a $6.4 million unsecured note guaranteed by certain stockholders of the purchaser, which bears interest at a rate of 10% and is due in July 2003. As of December 31, 2002, approximately $0.5 million remains outstanding under the secured note and the entire amount remains outstanding under the unsecured note.

 

In December 2002, the Company consummated the sale of the building where it maintained its corporate headquarters for approximately $68.0 million and recognized a gain on disposal of approximately $5.7 million (net of an income tax provision of $2.9 million). Proceeds from the sale were approximately $68.0 million in cash. Approximately $38.5 million of these proceeds were used to retire the building’s existing mortgage. As the Company maintains its corporate offices within the building, it also entered into a lease agreement for approximately 11.5% of the building’s total office space. The lease has been classified as an operating lease and approximately $5.9 million of additional gain has been deferred in accordance with SFAS No. 13, “Accounting for Leases,” as amended.

 

In December 2002, the Company committed to a plan to sell an office building. In January 2003, the Company entered in to a purchase and sale agreement to sell the office building for approximately $10.6 million in cash. As of December 31, 2002, the Company recorded an estimated loss on disposal of $3.2 million (net of an income tax benefit of $1.8 million) based on the estimated net proceeds expected to be received upon disposition.

 

Both office buildings were held as rental property and previously reported in the rental and management segment.

 

In fourth quarter of 2002, the Company committed to sell Flash Technologies, Inc., its remaining components business (previously reported in the network development services segment). In January 2003, the Company consummated the sale for approximately $41.1 million in cash, subject to a post-closing working capital adjustment. The estimated sale proceeds approximated the carrying value of the business.

 

In December 2002, the Company committed to a plan to sell Verestar. In February 2003, the Company consummated the sale of Maritime Telecommunications Network (MTN), a subsidiary of Verestar, for approximately $26.8 million in cash, subject to a post-closing working capital adjustment. The estimated sale proceeds approximated the carrying value of the business. The Company expects to sell the remaining portion of Verestar by December 31, 2003.

As of December 31, 2002, the Company had assets held for sale of approximately $234.7 million and liabilities held for sale of approximately $165.0 million. These amounts are comprised of the assets and liabilities of Verestar, Flash Technologies and an office building. The assets held for sale primarily represent: accounts receivable, net of $21.8 million, inventory of $7.2 million, prepaid and other current assets of $6.3 million, property and equipment, net of $178.8 million and intangible assets and other long term assets of $20.6 million. The liabilities held for sale primarily represent: $116.9 million of capital lease obligations, $9.7 million of accounts payable, $26.7 million of accrued expenses, $3.5 million of unearned revenue and $8.2 million of other long-term liabilities.

 

3.    COSTS   AND EARNINGS IN EXCESS OF BILLINGS ON UNCOMPLETED CONTRACTS AND UNBILLED RECEIVABLES

 

The Company derives a portion of its network development services revenue from customer contracts that either provide for billing only after certain milestones within contracts have been achieved or provide for progress billings as the Company fulfills its obligations under the related contracts. As the Company recognizes revenue on these contracts using the percentage-of-completion, cost plus profit and time and materials methodologies, such contracts may give rise to revenue which has been earned, but, as of a certain point in time, remains unbilled. Such amounts (along with unbilled rental revenue) are included in costs and earnings in excess of billings on uncompleted contracts and unbilled receivables in the accompanying consolidated balance sheets. These contracts may also give rise to billings that are in excess of amounts actually earned as of a certain point in time. The excess of amounts billed over the amount earned on these contracts is reflected (along with customer rent received in advance) in billings in excess of costs and earnings on uncompleted contracts and unearned revenue in the accompanying consolidated balance sheets.

5.    GOODWILL AND OTHER INTANGIBLE ASSETS

 

As of January 1, 2002, the Company adopted the provisions of SFAS No. 142 “Goodwill and Other Intangible Assets.” SFAS No. 142 requires that goodwill and intangible assets with indefinite lives no longer be amortized, but reviewed for impairment at least annually. Intangible assets that are deemed to have a definite life will continue to be amortized over their useful lives. SFAS No. 142 also required that, as of January 1, 2002, the Company assess whether its goodwill was impaired by performing a transitional impairment test. This impairment test was comprised of two steps. The initial step (required to be completed within six months of adopting this standard) was designed to identify potential goodwill impairment by comparing an estimate of the fair value of the applicable reporting unit to its carrying value, including goodwill. If the carrying value exceeded fair value, a second step was performed, which compared the implied fair value of the applicable reporting unit’s goodwill with the carrying amount of that goodwill, to measure the amount of goodwill impairment, if any.

 

F-16


Table of Contents

AMERICAN TOWER CORPORATION AND SUBSIDIARIES

 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

 

The Company completed its transitional impairment testing in the second quarter of 2002 and concluded that all of the goodwill related to its satellite and fiber network access services (SFNA) segment and the majority of the goodwill in the network development services segment was impaired. As a result, the Company recognized a $562.6 million non-cash charge (net of a tax benefit of $14.4 million) related to the write-down of goodwill to its fair value. In accordance with the provisions of SFAS No. 142, the charge is included in the results of operations for the year ended December 31, 2002 as the cumulative effect of a change in accounting principle.

 

A description of the Company’s reporting units (by segment) and the results of the related transitional impairment testing are as follows:

 

SFNA—SFNA was a single segment and reporting unit until December 2002, when the Company committed to a plan to dispose of Verestar, which comprised the entire SFNA segment. The Company recorded an impairment charge of $189.3 million relating to the impairment of goodwill in this reporting unit. The fair value of this reporting unit was determined based on an independent third party appraisal.

 

Network Development Services (Services)—As of January 1, 2002, the reporting units in the Company’s network development services segment included Kline Iron & Steel (Kline), Specialty Constructors, Galaxy Engineering, MTS Components and Flash Technologies. The Company estimated the fair value of these reporting units utilizing future discounted cash flows and market information as to the value of each reporting unit on January 1, 2002. The Company recorded an impairment charge of $387.8 million related to the impairment of goodwill within these reporting units. Such charge included full impairment for all of the goodwill within the reporting units except Kline, for which only a partial impairment was recorded. As discussed in note 2, the assets of the MTS Components reporting unit were sold in July 2002 and the Flash Technologies reporting unit was reclassified to discontinued operations effective December 2002 and sold in January 2003.

 

Rental and Management (RM)—The Company obtained an independent third party appraisal of the rental and management reporting unit that contains goodwill and determined that goodwill was not impaired.

 

With the adoption of SFAS No. 142, the Company also reassessed the useful lives and residual values of all acquired intangible assets. Based on those assessments, no adjustments were made to the amortization periods or residual values of the Company’s remaining intangible assets.

 

The Company has selected December 1st as the date to perform its annual impairment test. In December 2002, the Company completed its annual impairment testing under the provisions of SFAS No. 142 with respect to its rental and management reporting unit that contains goodwill and its Kline reporting unit (the only services business with remaining goodwill). In performing its testing, the Company obtained an independent third party appraisal of its rental and management reporting unit that contains goodwill and concluded that an impairment of the goodwill related to that unit was not required. In addition, the Company utilized market information to value its Kline reporting unit and determined that the remaining goodwill related to Kline was not impaired.

The Company’s network location intangible represents the excess of purchase price over tangible and identifiable intangible assets related to asset acquisitions. The Company amortizes its intangible assets over periods ranging from three to fifteen years. Amortization of intangible assets for the years ended December 31, 2002 and 2001 aggregated approximately $88.1 million and $90.2 million, respectively. The Company expects to record amortization expense of approximately $90.3 million for the year ended December 31, 2003 and $89.7 million for the years ended December 31, 2004, 2005 and 2006, respectively, and $87.3 million for the year ended December 31, 2007.

 

6.    NOTES RECEIVABLE

 

In 2000, the Company loaned TV Azteca S.A. de C.V., the owner of a major national television network in Mexico, $119.8 million. The loan, which bears interest at 12.87%, payable quarterly, was discounted by the Company, as the fair value interest rate at the date of the loan was determined to be 14.25%. As of December 31, 2002, approximately $119.8 million undiscounted ($108.2 million discounted) under the loan was outstanding. The term of the loan is seventy years; however, the loan may be prepaid by TV Azteca without penalty during the last fifty years of the agreement. The discount on the loan is being amortized to interest income — TV Azteca, net using the effective interest method over the seventy-year term of the loan.

 

Simultaneous with the signing of the loan agreement, the Company also entered into a seventy year Economic Rights Agreement with TV Azteca regarding space not used by TV Azteca on approximately 190 of its broadcast towers. In exchange for the issuance of the below market interest rate loan discussed above and the annual payment of $1.5 million to TV Azteca (under the Economic Rights Agreement), the Company has the right to market and lease the unused tower space on the broadcast towers (the Economic Rights). TV Azteca retains title to these towers and is responsible for their operation and maintenance. The Company is entitled to 100% of the revenues generated from leases with tenants on the unused space and is responsible for any incremental operating expenses associated with those tenants.

 

The term of the Economic Rights Agreement is seventy years; however, TV Azteca has the right to purchase, at fair market value, the Economic Rights from the Company at any time during the last fifty years of the agreement. Should TV Azteca elect to purchase the Economic Rights (in whole or in part), it would also be obligated to repay a proportional amount of the loan discussed above at the time of such election. The Company’s obligation to pay TV Azteca $1.5 million annually would also be reduced proportionally.

 

The Company has accounted for the annual payment of $1.5 million as a capital lease (initially recording an asset and a corresponding liability of approximately $18.6 million). The capital lease asset and the discount on the note, which aggregate approximately $30.2 million, represent the cost to acquire the Economic Rights and are being amortized over the seventy-year life of the Economic Rights agreement.

 

On a quarterly basis, the Company assesses the recoverability of its note receivable from TV Azteca. As of December 31, 2002, the Company has assessed the recoverability of the note receivable from TV Azteca and concluded that no adjustment to its carrying value is required.

 

An executive officer and director of the Company became a director of TV Azteca in December 1999.

 

As of December 31, 2002 and 2001, the Company also had several other current and long-term notes receivable outstanding of approximately $9.3 million and $6.8 million, respectively. These notes bear interest at rates ranging from 9% to 11% and mature in periods through 2011.

The following is a description of the Company’s outstanding debt as of December 31, 2002:

 

Credit Facilities—The Company’s credit facilities (prior to the February 2003 amendment discussed in note 19) provided for a borrowing capacity of up to $2.0 billion (after giving effect to the amendment—$1.575 billion). The Company’s principal operating subsidiaries (other than Verestar) are the borrowers under the credit facilities. Borrowers under the credit facilities are subject to compliance with certain financial ratios.

 

    a $650.0 million (as amended—$425.0 million) revolving credit facility, of which $160.0 million was drawn on December 31, 2002, maturing on June 30, 2007;

 

    an $850.0 million (as amended—$725.0 million) multi-draw term loan A, which was fully drawn on December 31, 2002, maturing on June 30, 2007; and

 

    a $500.0 million (as amended—$425.0 million) term loan B, which was fully drawn on December 31, 2002, maturing on December 31, 2007.

 

The credit facilities are scheduled to amortize quarterly commencing on March 31, 2003 through their maturity dates based on defined percentages of outstanding commitment and principal balances. The Company may also be required to make additional principal payments should operating cash flows exceed certain amounts. Any amounts repaid under the term loan A and the term loan B will reduce future borrowing capacity under these facilities to the extent of the amount repaid.

 

In January 2002, the Company terminated a $250.0 million multi-draw term loan C facility, none of which facility had been drawn. As a result of this termination, the Company recorded a charge of $7.2 million to loss on term loan cancellation in the accompanying 2002 consolidated statement of operations related to the write-off of certain deferred financing fees associated with this facility.

 

In February 2001, the Company’s Mexican subsidiary, American Tower Corporation de Mexico, S. de R.L. de C.V. (ATC Mexico) and two of its subsidiaries consummated a loan agreement with a group of banks providing a credit facility of an initial aggregate amount of $95.0 million (the Mexican Credit Facility). As of December 31, 2001, an aggregate of $95.0 million was outstanding under this loan agreement. In February 2002, the Company repaid all loans outstanding under the Mexican Credit Facility with borrowings under the credit facilities and substantially all of the Mexican subsidiaries became restricted subsidiaries under the credit facilities. As a result of such repayment,

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

the Company recognized an extraordinary loss on extinguishment of debt of approximately $1.1 million (net of an income tax benefit of $0.6 million).

 

Interest rates for the revolving credit facility and the term loan A are determined at the option of the Company (at a margin based on leverage) at either 2.0% to 3.25% above the LIBOR Rate or 1.0% to 2.25% above the defined Base Rate. Notwithstanding the foregoing, the applicable margin with respect to the revolving credit facility and the term loan A from January 1, 2003 through September 30, 2003 shall not be less than 1.5% with respect to Base Rate advances and 2.5% with respect to LIBOR advances. Interest rates for the term loan B are determined (at a margin based on leverage) at 3.5% above LIBOR or 2.5% above the defined Base Rate. The Company is required to pay quarterly commitment fees on the undrawn portion of the facility, ranging from 0.5% to 1.0% per annum, depending on the level of facility usage. In addition, the credit facilities require compliance with financial coverage ratios that measure operating cash flow against total debt, operating cash flow against senior debt, interest coverage, pro forma debt service and fixed charges, as defined in the credit facilities. The credit facilities also contain financial and operational covenants and other restrictions which the Company, the borrowers and their restricted subsidiaries must comply with, whether or not there are borrowings outstanding. Such covenants and restrictions include restrictions on certain types of acquisitions, indebtedness, investments, liens, capital expenditures, and the ability of the borrowers to pay dividends and make other distributions. The borrowers under the credit facilities include the Company’s principal domestic operating subsidiaries (other than Verestar). The Company and the restricted subsidiaries (as defined in the credit facilities) and Verestar and its subsidiaries have guaranteed all of the loans under the credit facilities. These loans are secured by liens on substantially all assets of the Company, the borrowers, the restricted subsidiaries and Verestar and its subsidiaries. The credit facilities also restrict the borrowers’, the restricted subsidiaries’ and Verestar’s and its subsidiaries’ ability to transfer funds to the Company. As of December 31, 2002 substantially all assets of the Company are held by the borrowers and the restricted subsidiaries.

 

Availability at December 31, 2002 under the revolving credit facilities was $470.8 million, net of $19.2 million of outstanding letters of credit. The availability was reduced to $245.8 million, giving effect to the February 2003 amendment. (See note 19).

 

Prior to entering into of the credit facilities described above, the Company maintained credit facilities that provided for total capacity of $925.0 million. All amounts outstanding under the prior credit facilities were repaid in January 2000 with proceeds from the new credit facilities. In connection with the repayment of borrowings under the Company’s prior credit facilities, the Company recognized an extraordinary loss on extinguishment of debt of approximately $3.0 million (net of a tax benefit of $2.0 million), in January 2000.

 

Additionally, in February 2000, the Company repaid certain debt assumed in connection with an acquisition. Such debt repayment was at a premium of the outstanding principal balance. Accordingly, the Company recognized an extraordinary loss of $1.3 million (net of an income tax benefit of $0.9 million) from the extinguishment of this debt in 2000.

 

For the years ended December 31, 2002, 2001 and 2000, the combined weighted average interest rate related to the Company’s credit facilities was 4.41%, 7.26% and 9.56% respectively. Commitment fees incurred by the Company related to the credit facilities aggregated approximately $5,454,000, $7,478,000 and $9,777,000 for the years ended December 31, 2002, 2001 and 2000, respectively.

 

9 3/8% Senior Notes—In January 2001, the Company completed a private notes placement of $1.0 billion 9 3/8% senior notes (senior notes), issued at 100% of their face amount. The senior notes mature on February 1, 2009.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

 

Interest on the senior notes is payable semiannually on February 1 and August 1. The indenture governing the senior notes contains certain restrictive covenants including restrictions on the Company’s ability to incur more debt, guarantee debt, pay dividends and make certain investments. Proceeds from the senior notes placement were used to finance construction of towers, fund acquisitions and for general corporate purposes. The senior notes rank equally with the Company’s 5%, 6.25% and 2.25% convertible notes, described below, and are structurally and effectively junior to indebtedness outstanding under the Credit Facilities.

 

As of December 31, 2002 and 2001, the Company has $1.0 billion outstanding under the senior notes.

 

5% Convertible Notes—In February 2000, the Company completed a private placement of $450.0 million 5% Convertible Notes (5% Notes), issued at 100% of their face amount. The 5% Notes mature on February 15, 2010. Interest on the 5% Notes is payable semiannually on February 15 and August 15 of each year. The indenture governing the 5% Notes does not contain any restrictive covenants. The credit facilities restrict the Company’s ability to repurchase the convertible notes for cash from the proceeds of borrowings under the credit facilities or from internally generated funds from any of the Company’s restricted subsidiaries (under its credit facilities).

 

The 5% Notes are convertible at any time into shares of the Company’s Class A common stock at a conversion price of $51.50 per share, subject to adjustment in certain cases. The Company cannot redeem the 5% Notes prior to February 20, 2003. The initial redemption price on the 5% Notes is 102.5% of the principal amount, subject to ratable declines immediately after February 15 of the following year to 100% of the principal amount in 2006. The holders have the option of requiring the Company to repurchase all or any of the 5% Notes on February 20, 2007 at their principal amount, together with accrued and unpaid interest. The Company may, subject to certain conditions in the applicable indenture (including the condition that the Company’s Class A common stock trade on a national securities exchange or Nasdaq), elect to pay the repurchase price in cash or shares of Class A common stock, or any combination thereof. The 5% Notes rank equally with the 6.25% and 2.25% Notes described below and the senior notes and are structurally and effectively junior to indebtedness outstanding under the Credit Facilities and the 12.25% senior subordinated discount notes described in note 19.

 

As of December 31, 2002 and 2001, the Company had $450.0 million outstanding under the 5% Notes.

 

2.25% and 6.25% Convertible Notes—In October 1999, the Company completed a private placement of $300.0 million 6.25% Convertible Notes (6.25% Notes), issued at 100% of their face amount and $425.5 million 2.25% Convertible Notes (2.25% Notes), issued at 70.52% of their face amount (collectively, the “Notes”). The yield to maturity on the 2.25% Notes is 6.25%, giving effect to the original discount. The Notes mature on October 15, 2009. Interest on the Notes is payable semiannually on April 15 and October 15 of each year.

 

The 6.25% Notes and 2.25% Notes are convertible at any time, at the option of the holder, into the Company’s Class A common stock at a conversion price of $24.40 per share and $24.00 per share, respectively, subject to adjustment in certain events. The Company may redeem the Notes at any time on or after October 22, 2002. The initial redemption price on the 6.25% Notes is 103.125% of the principal amount, subject to ratable declines immediately after October 15 of each following year to 100% of the principal amount in 2005. The 2.25% Notes are redeemable incrementally at increasing prices designed to reflect the accrued original issue discount. The holders have the option of requiring the Company to repurchase all or a portion of the 6.25% Notes on October 22, 2006 at their principal amount, together with accrued and unpaid interest, and all or a portion of the 2.25% Notes on October 22, 2003 at $802.93 per note (accreted through October 22, 2003), plus accrued and unpaid interest. The Company may, subject to certain conditions in the applicable indenture (including the condition that the Company’s Class A common stock trade on a national securities exchange or Nasdaq), elect to pay the repurchase price on the Notes in cash or shares of Class A common stock or any combination thereof. The credit facilities restrict the Company’s ability to repurchase the convertible notes for cash from the proceeds of borrowings under the credit facilities or from internally generated funds from any of the Company’s restricted

subsidiaries (under its credit facilities). The 6.25% Notes and 2.25% Notes rank equally with one another, the 5% Notes and the senior notes and are structurally and effectively junior to indebtedness outstanding under the credit facilities and the 12.25% senior subordinated discount notes described in note 19.

 

Based on the principal amount of the 2.25% notes outstanding as of December 31, 2002, the Company may be required to repurchase up to $216.7 million (accreted through October 22, 2003) principal amount of its 2.25% convertible notes on October 22, 2003, if all of the holders exercise their put right. Based on the above, the $210.9 million outstanding on the 2.25% notes has been classified as a current liability in the accompanying 2002 consolidated balance sheet. (See note 19).

 

In August of 2001, the Company acquired an aggregate of $82.5 million face amount ($61.6 million carrying amount) of the 2.25% Notes for an aggregate of 2,424,123 shares of Class A common stock. As an inducement to the noteholders to convert all or a portion of their holdings, the Company issued an aggregate of 1,538,414 shares of Class A common stock to such holders in addition to the amounts issuable upon conversion of those notes as provided in the applicable indentures. The Company made these exchanges pursuant to negotiated transactions with a limited number of noteholders. As a consequence of those exchanges, the Company recorded note conversion expense of approximately $26.3 million in the third quarter of 2001 which represents the fair market value of the inducement shares.

 

In May 2000, the Company acquired an aggregate of $87.3 million of the 6.25% Notes and $73.1 million face amount of the 2.25% Notes for an aggregate of 5,724,180 shares of Class A common stock. As an inducement to the noteholders to convert all or a portion of their holdings, the Company issued an aggregate of 402,414 shares of Class A common stock to such holders in addition to the amounts issuable upon conversion of those notes as provided in the applicable indentures. The Company made these exchanges pursuant to negotiated transactions with a limited number of noteholders. As a consequence of those exchanges, the Company recorded note conversion expense of approximately $17.0 million during the second quarter of 2000 which represents the fair market value of the inducement shares.

 

As of December 31, 2002 and 2001, the Company had $210.9 million and $204.2 million outstanding, respectively, under the 2.25% Notes. Further, as of December 31, 2002 and 2001, the Company had $212.7 million outstanding under the 6.25% Notes.

 

Notes Payable—Notes payable approximated $33.8 million and $73.1 million as of December 31, 2002 and 2001, respectively. These obligations bear interest at rates ranging from 7.0% to 12.0% and mature in periods ranging from less than one year to approximately five years.

 

Capital Lease Obligations—The Company’s capital lease obligations, which approximate $47.2 million and $177.0 million as of December 31, 2002 and 2001, respectively, expire in periods ranging from less than one year to approximately seventy years. As of December 31, 2002, approximately $116.9 million of aggregate principal payments for Verestar capital leases are included in liabilities held for sale in the accompanying consolidated balance sheet.

The holders of the Company’s convertible notes have the right to require the Company to repurchase their notes on specified dates prior to their maturity dates in 2009 and 2010, but we may pay the purchase price by issuing shares of Class A common stock, subject to certain conditions. Obligations with respect to the right of the holders to put the 2.25% notes, 6.25% notes and 5% notes have been included in the table above as if such notes mature at the date of their put rights in 2003, 2006 and 2007, respectively.

 

8.    DERIVATIVE FINANCIAL INSTRUMENTS

 

Under the terms of the Company’s Credit Facilities, the Company is required to enter into interest rate protection agreements on at least 50% of its variable rate debt. Under these agreements, the Company is exposed to credit risk to the extent that a counterparty fails to meet the terms of a contract. Such exposure is limited to the current value of the contract at the time the counterparty fails to perform. The Company believes its contracts as of December 31, 2002 are with credit worthy institutions. As of December 31, 2002, the Company had interest rate protection agreements outstanding as follows (in thousands):

Acquisition Commitments—As of December 31, 2002, the Company was party to an agreement relating to the acquisition of tower assets from a third party for an estimated aggregate purchase price of approximately $74.0 million. The Company may pursue the acquisitions of other properties and businesses in new and existing locations, although there are no definitive material agreements with respect thereto.

 

Build-to-Suit Agreements—As of December 31, 2002, the Company was party to various arrangements relating to the construction of tower sites under existing build-to-suit agreements. Under the terms of the agreements, the Company is obligated to construct up to 1,000 towers over a five year period which includes 650 towers in Mexico and 350 towers in Brazil over the next three years. The Company is in the process of renegotiating several of these agreements to reduce its overall commitment; however, there can be no assurance that it will be successful in doing so.

 

ATC Separation—The Company was a wholly owned subsidiary of American Radio Systems Corporation (American Radio) until consummation of the spin-off of the Company from American Radio on June 4, 1998 (the ATC Separation). On June 4, 1998, the merger of American Radio and a subsidiary of CBS Corporation (CBS) was consummated. As a result of the merger, all of the outstanding shares of the Company’s common stock owned by American Radio were distributed or reserved for distribution to American Radio stockholders, and the Company ceased to be a subsidiary of, or to be otherwise affiliated with, American Radio. Furthermore, from that day forward the Company began operating as an independent publicly traded company.

 

In connection with the ATC Separation, the Company agreed to reimburse CBS for any tax liabilities incurred by American Radio as a result of the transaction. Upon completion of the final American Radio tax returns, the amount of these tax liabilities was determined and paid by the Company. The Company continues to be obligated under a tax indemnification agreement with CBS, however, until June 30, 2003, subject to the extension of federal and applicable state statutes of limitations.

 

The Company is currently aware that the Internal Revenue Service (IRS) is in the process of auditing certain tax returns filed by CBS and its predecessors, including those that relate to American Radio and the ATC Separation transaction. In the event that the IRS imposes additional tax liabilities on American Radio relating to the ATC Separation, the Company would be obligated to reimburse CBS for such liabilities. The Company cannot currently anticipate or estimate the potential additional tax liabilities, if any, that may be imposed by the IRS, however, such amounts could be material to the Company’s consolidated financial position and results of operations. The Company is not aware of any material obligations relating to this tax indemnity as of December 31, 2002. Accordingly, no amounts have been provided for in the consolidated financial statements relating to this indemnification.

Litigation—The Company periodically becomes involved in various claims and lawsuits that are incidental to its business. In the opinion of management, after consultation with counsel, there are no matters currently pending which would, in the event of adverse outcome, have a material impact on the Company’s consolidated financial position, the results of its operations or liquidity.

 

10.    RELATED PARTY TRANSACTIONS

 

JP Morgan Chase Bank (Chase) is a lender under the Company’s credit facilities and had participation percentages ranging from 1.68% to 6.67% during 2002, 2001 and 2000. Chase is an affiliate of J.P. Morgan Partners, LLC (JPMP), which indirectly controls J.P. Morgan Partners (BHCA), L.P. (JPLP) and J.P. Morgan Partners (23ASBIC), LLC (JPSBIC), stockholders of the Company. A director of the Company is an Executive Partner of JPMP. At December 31, 2002, 2001 and 2000, the aggregate principal amount outstanding under the credit facilities was approximately $1.5 billion, $1.4 billion and $1.4 billion, respectively. Chase’s participation in the credit facilities at December 31, 2002 was 2.22%. Chase’s approximate share of interest and fees paid by the Company pursuant to its various credit arrangements was approximately $0.9 million, $1.5 million and  $3.2 million in 2002, 2001 and 2000, respectively.

 

In March 2001, the Company purchased 78,432 shares of Class B Common Stock, par value $0.01 per share, of America Connect, Inc., a Delaware corporation, from JPSBIC for 100,000 shares of the Company’s Class A common stock.

 

During 2002, 2001 and 2000, the Company made demand loans to five executive officers. As of December 31, 2002, all amounts have been repaid with the exception of $0.2 million outstanding from two executive officers and a $0.7 million note outstanding from a former employee and executive officer (which has repayment terms under the former executive’s severance agreement). As of December 31, 2001 and 2000, amounts outstanding under the loans approximated $1.0 million.

 

In October 2001, the Company consummated the sale of 8.7% of its Mexican subsidiary, ATC Mexico Holding Corp. (ATC Mexico Holding), to J. Michael Gearon, Jr., an executive officer and director, for $8.4 million.  Mr. Gearon paid $1.7 million in cash and delivered a 7% secured note due 2010 in the principal amount of  $6.7 million. The note, which accrues interest and is payable quarterly, is secured by certain shares of the Company’s Class A common stock owned by Mr. Gearon and his interest in ATC Mexico Holding. The purchase price represented the fair market value of an 8.7% interest in ATC Mexico Holding on the date of the sale as determined with the assistance of an independent appraiser. Mr. Gearon may require the Company to purchase his interest in ATC Mexico Holding, for its then fair market value, any time after the soonest to occur of July 1, 2004, a change in control (as defined in the stockholder agreement relating to Mr. Gearon’s investment) of the Company or ATC Mexico Holding, or Mr. Gearon’s death or disability. The Company has the right to purchase Mr. Gearon’s interest in ATC Mexico Holding for its then fair market value after the soonest to occur of July 1, 2005, Mr. Gearon’s death or disability or on either a Gearon Termination Event or a Forfeiture Event (each as defined in a stockholder agreement). Interest income (paid quarterly) on the 7% secured note approximated $470,000 and $104,000 for the years ended December 31, 2002 and 2001, respectively.

 

In January 2003, as a result of the occurrence of a change in control (as defined in the stockholder agreement), Mr. Gearon’s right to require the Company to purchase his interest in ATC Mexico Holding for its fair market value was accelerated and is currently exercisable.

 

During the years ended December 31, 2002, 2001 and 2000, the Company retained several wholly-owned subsidiaries of Nordblom Co. Inc. to provide various real estate services in connection with its acquisition, financing, ownership and leasing of several properties. Services rendered by those companies included advice in connection with the acquisition and arranging mortgage financing of the Company’s corporate headquarters building in Boston (which was sold in December 2002) and two other office buildings in which it has regional

offices; the management of those buildings; and the leasing of certain of them. The Company paid the Nordblom companies, including Nordic Properties, an affiliate of Nordblom, an aggregate of $574,000, $772,000 and $474,000 in 2002, 2001 and 2000, respectively. Two brothers and the father of the Company’s Chairman and Chief Executive Officer’s (Mr. Dodge) wife own the controlling interest of Nordblom Co. Inc. and Nordic Properties. Mr. Dodge’s wife has no interest in Nordblom Co. Inc. or Nordic Properties and Mr. Dodge was not involved in the negotiation of any of the arrangements. The Company believes that all of the arrangements with the Nordblom companies are on terms and conditions that are customary in the industry and at least as favorable to it as could be obtained from an unrelated real estate management company.

 

In December 2002, in connection with a potential financing transaction between the Company and SPO Partners II, LP (SPO), the Company entered into a letter agreement with SPO, which at the time was a holder of more than 5% of its Class A common stock. The agreement provided for a $2.0 million break-up fee (plus expenses) payable to SPO in the event that the Company consummated an alternative financing transaction. As a result of the discount notes offering described in note 19, the Company expects to pay this $2.0 million break-up fee and reimburse certain expenses to SPO in the first quarter of 2003.

 

11.    RESTRUCTURING

 

In November 2001, the Company announced a restructuring of the organization and implemented an initiative to consolidate operations in each of its business segments. During the year ended December 31, 2001, the Company incurred employee separation costs associated with the termination of approximately 525 employees (primarily tower development and administrative employees) and facility closing costs associated with the shut-down of approximately 20 field office locations aggregating $5.2 million. As a result of these continuing initiatives, in 2002, the Company incurred employee separation costs associated with the termination of approximately 460 employees (primarily development and administration) as well as costs associated with the termination of lease obligations and other incremental facility closing costs aggregating $10.6 million. These costs are reflected as restructuring expense in the accompanying 2002 and 2001 consolidated statements of operations.

 

The following table displays activity with respect to the accrued restructuring liability related to continuing operations for the years ended December 31, 2001 and 2002 (in thousands). The accrued restructuring liability related to continuing operations is reflected in accounts payable and accrued expenses in the accompanying consolidated balance sheets as of December 31, 2001 and 2002.

$1.4 million of employee separation costs and facility closing costs related to businesses reported as discontinued operations. These costs are included within loss from discontinued operations, net in the accompanying consolidated statement of operations for the years ended December 31, 2002 and 2001, respectively. The accrued restructuring liability of $6.7 million related to discontinued operations is reflected in liabilities held for sale in the accompanying December 31, 2002 consolidated balance sheet.

 

There were no material changes in estimates related to the accrued restructuring liabilities during the years ended December 31, 2001 or 2002. The Company expects to pay the balance of the employee separation liabilities related to continuing operations in the first quarter of 2003. Additionally, the Company is in the process of negotiating certain lease terminations associated with both continuing and discontinued operations. As of December 31, 2002, the Company has completed its restructuring initiatives to consolidate operations and does not anticipate future charges associated with this restructuring.

SFAS No. 109, “Accounting for Income Taxes,” requires that companies record a valuation allowance when it is “more likely than not that some portion or all of the deferred tax assets will not be realized.” During the year ended December 31, 2002, the Company recorded a valuation allowance of $27.5 million in connection with a plan to implement a tax planning strategy to accelerate the utilization of certain federal net operating losses. The valuation allowance represents the estimate net tax benefit and costs in connection with implementing this strategy. At December 31, 2002, the Company has provided a valuation allowance of approximately $118.6 million, primarily related to state net operating loss carryforwards, capital loss carryforwards and the lost tax benefit and costs associated with implementing our tax planning strategy. The Company has not provided a valuation allowance for the remaining net deferred tax assets, primarily its federal net operating loss carryforwards, as management believes the Company will have sufficient time to realize these assets during the twenty-year carryforward period.

 

The Company intends to recover a portion of its deferred tax asset from its tax planning strategy to accelerate the utilization of certain federal net operating losses. The recoverability of its remaining net deferred tax asset has been assessed utilizing stable state (no growth) projections based on its current operations. The projections show a significant decrease in depreciation and interest expense in the later years of the carryforward period as a result of a significant portion of its assets being fully depreciated during the first fifteen years of the carryforward

period and debt repayments reducing interest expense. Accordingly, the recoverability of the net deferred tax asset is not dependent on material improvements to operations, material asset sales or other non-routine transactions. Based on its current outlook of future taxable income during the carryforward period, management believes that the net deferred tax asset will be realized. The realization of the Company’s deferred tax assets will be dependent upon its ability to generate approximately $800.0 million in taxable income from January 1, 2003 to December 31, 2022. If the Company is unable to generate sufficient taxable income in the future, or implement its tax planning strategy, it will be required to reduce its net deferred tax asset through a charge to income tax expense, which would result in a corresponding decrease in stockholders’ equity.

 

13.    STOCKHOLDERS’ EQUITY

 

Preferred Stock

 

As of December 31, 2002 the Company was authorized to issue up to 20.0 million shares of $.01 par value preferred stock. As of December 31, 2002 and 2001 there were no preferred shares issued or outstanding.

The Class A and B common stockholders are entitled to one and ten votes per share, respectively. The Class C common stock is non-voting. In addition, holders of Class B and C common stock may exchange their shares on a one-to-one basis for shares of Class A common stock. During the years ended December 31, 2002, 2001 and 2000, holders of Class B and Class C common stock exchanged 84,699, 93,236 and 613,286 of their shares, respectively, for shares of Class A common stock.

 

Warrants

 

As of December 31, 2002, the Company had warrants outstanding to purchase approximately 2.7 million shares of its Class A common stock at an exercise price of $22.00 per share. These vested warrants expire through 2005. (See note 14).

 

Principal Equity Transactions

 

The following is a summary of the Company’s principal equity transactions during the years ended  December 31, 2001 and 2000. There were no principal equity transactions during the year ended December 31, 2002.

 

2001

2000

 

In June 2000, the Company completed a public offering of 12,500,000 shares of its Class A common stock at $41.125 per share. The Company’s net proceeds of the offering (after deduction of the offering expenses) were approximately $513.9 million. The Company used the proceeds to reduce borrowings under the Credit Facilities and to finance acquisitions and the construction of towers, as well as for general working capital purposes.

 

Stock Issued for Acquisitions—See note 14 of the consolidated financial statements for issuances of warrants, options and common stock in connection with the Company’s acquisitions.

 

Stock Option Plans—The Company maintains a stock option plan for directors, officers and employees (the Plan), which provides for non qualified and incentive stock options. Exercise prices in the case of incentive stock options are not less than the fair market value of the underlying common stock on the date of grant. Exercise prices in the case of non-qualified stock options are set at the discretion of the Company’s Board of Directors (which to date has not been less than the fair market value on the date of grant).

 

The option pool under the Plan consists of an aggregate of 27,000,000 shares of common stock. In addition to the shares authorized under the Plan, options to purchase approximately 2,042,000 shares of common stock were outstanding as of December 31, 2002 outside of the Plan. Options outside the Plan are the result of the exchange of certain American Radio options that occurred pursuant to the ATC Separation and the assumption of certain options that occurred pursuant to certain mergers.

 

Option grants generally vest ratably over various periods, generally three to five years, commencing one year from the date of grant. Option grants generally expire ten years from the date of grant.

Pro Forma Disclosure—As described in note 1, the Company uses APB No. 25 to account for equity grants and awards to employees. Accordingly, there is no compensation expense related to option grants reflected in the accompanying consolidated financial statements. The Company has adopted the disclosure-only provisions of SFAS No. 123, as amended by SFAS No. 148, and has presented such disclosure in note 1. The “fair value” of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The weighted average fair values of the Company’s options granted during 2002, 2001 and 2000 were $2.23, $9.04 and $18.19 per share, respectively. Key assumptions used to apply this pricing model are as follows:

Voluntary Option Exchange—As a result of a voluntary option exchange program, the Company accepted for surrender and cancelled options to purchase 3,471,211 shares of its Class A common stock on October 26, 2001 and issued 2,027,612 options in May 2002 to eligible employees with an exercise price equal to the fair market value of the Class A common stock on the date of grant of $3.84 per share. The program, which was offered to both full and part-time employees, excluding most of the Company’s executive officers, called for the grant (at least six months and one day from the surrender date to employees still employed on that date) of new options exercisable for two shares of Class A common stock for every three shares of Class A common stock issuable upon exercise of a surrendered option. No options were granted to any employees who participated in the exchange offer between the cancellation date and the new grant date.

ATC Teleports Stock Option Plan—During 1999, Verestar’s Board of Directors approved the formation of the ATC Teleports Stock Option Plan (ATC Teleports Plan) that provided for the issuance of options to officers, employees, directors and consultants of Verestar. As approved in 1999, the ATC Teleports Plan limited the number of shares of common stock which could be granted to an aggregate of 1,000,000 shares. Provisions of the original ATC Teleports Plan specified that options granted would vest at the discretion of Verestar’s Board of Directors and expire ten years from the date of grant.

 

During 2000, Verestar granted 809,400 options to purchase shares of Verestar common stock to officers, directors and employees under the ATC Teleports Plan. Such options were issued at one time with an exercise price of $7.75 per share. The exercise price per share was at fair market value based on an independent appraisal performed at the Company’s request. The fair value of ATC Teleports Plan options granted during 2000 were $1.97 per share as determined by using the Black-Scholes option pricing model. During 2002 and 2001, no options were granted and 142,000 and 340,800 options were terminated under the ATC Teleports Plan. In addition, no options under the ATC Teleports Plan were exercised during 2002, 2001 or 2000, and 150,520 of the 486,600 options outstanding as of December 31, 2001 were exercisable. No options were exercisable as of December 31, 2000.

 

On November 1, 2002, Verestar’s Board of Directors approved a resolution that called for a reverse split of all Verestar’s issued and outstanding common stock at the rate of 5,000 to one. This resolution further stated that all options issued by Verestar that were outstanding as of November 1, 2002 should be accordingly reduced and that the exercise price per share should be increased to give effect to the reverse split. As a result, the new exercise price per share for the outstanding options under the ATC Teleports Plan became $38,750. As of December 31, 2002, 65 options were outstanding under the ATC Teleports Plan, of which 13 were exercisable.

 

ATC Mexico Stock Option Plan—During 2001, ATC Mexico Holding’s Board of Directors approved the formation of the ATC Mexico Stock Option Plan (ATC Mexico Plan) that provides for the issuance of options to officers, employees, directors and consultants of ATC Mexico. The ATC Mexico Plan limits the number of shares of common stock which may be granted to an aggregate of 360 shares, subject to adjustment based on changes in ATC Mexico’s capital structure. During 2002, ATC Mexico granted 330 options to purchase shares of ATC Mexico common stock to officers and employees. Such options were issued at one time with an exercise price of $10,000 per share. The exercise price per share was at fair market value based on an independent appraisal performed at the Company’s request. The fair value of ATC Mexico Plan options granted during 2002 were $3,611 per share as determined by using the Black-Scholes option pricing model. Options granted vest upon the earlier to occur of (a) the exercise by or on behalf of J. Michael Gearon, Jr. of his right to sell his interest in ATC Mexico Holding to the Company, (b) the exercise by the Company of its right to acquire Mr. Gearon’s interest in ATC Mexico Holding, or (c) a change of control of the Company (as defined in the ATC Mexico Plan), and expire ten years from the date of grant. (See note 10). No options under the ATC Mexico Plan were exercised or cancelled in 2002 and no options were exercisable as of December 31, 2002.

 

Employee Stock Purchase Plan—During 2000, the Company established an employee stock purchase plan for all eligible employees. Under the plan, shares of the Company’s common stock may be purchased at six-month intervals at 85% of the lower of the fair market value on the first or the last day of each offering period. Employees may purchase shares having a value not exceeding 15% of their gross compensation during an offering period and may not purchase more than $25,000 worth of stock in a calendar year (based on market values at the beginning of each offering period). During 2002, 2001 and 2000, employees purchased 396,295, 231,257 and 33,794 shares, respectively, at weighted average prices per share of $3.24, $11.90 and $25.61, respectively. At December 31, 2002, 4,338,654 shares remain reserved for future issuance under the plan.

14.    ACQUISITIONS

 

General—The acquisitions consummated during 2002, 2001 and 2000 have been accounted for under the purchase method of accounting. The purchase prices have been allocated to the net assets acquired (principally tangible and intangible assets) and the liabilities assumed based on their estimated fair values at the date of acquisition. The Company has recorded the excess of purchase price over the estimated fair value of the net assets acquired as goodwill and other intangible assets. For certain acquisitions, the consolidated financial statements reflect preliminary allocations of purchase price, as appraisals of the net assets acquired have not been finalized. The Company does not expect any changes in depreciation and amortization from the finalization of these appraisals to be material to its consolidated results of operations.

 

During the years ended December 31, 2002, 2001 and 2000, the Company primarily acquired its tower assets from third parties in one of three ways:

 

  the purchase of assets,

 

  the purchase of a business; or

 

  a capital lease.

 

The structure of the transaction affects the way the Company allocates purchase price within the consolidated financial statements. Specifically, in the case of an asset purchase, the Company allocates a portion of the purchase price to property and equipment for the appraised value of the tower (replacement cost), intangible assets for existing customer base and any other identifiable intangibles (if applicable). Any remaining purchase price is then recorded within intangible assets as a “network/location intangible.”

 

In the case of tower assets acquired through the purchase of a business, the allocation is similar to the above except that the remaining purchase price after valuing all assets (including towers and identifiable intangibles) and liabilities is recorded in accordance with SFAS No. 141, “Business Combinations,” as goodwill. For tower assets acquired through capital lease, which as of December 31, 2002, represented only the ALLTEL transaction (as discussed below), the entire asset value is recorded as a capital lease and is reflected in property and equipment in the accompanying consolidated financial statements.

 

Property and equipment, network/location intangibles and assets held under capital lease related to tower acquisitions are all amortized over a fifteen-year period.

 

2002 Acquisitions—During the year ended December 31, 2002, the Company’s acquisitions were limited to transactions involving the acquisition of various communications sites for an aggregate purchase price of approximately $55.7 million in cash. The principal transaction was as follows:

 

NII transaction—In December 2002, the Company entered into an agreement to acquire up to 540 communications sites from NII Holdings, Inc. (NII), predominantly in Mexico. The NII transaction is expected to occur through several closings for a total purchase price of $100.0 million in cash. In December 2002, the first of these closings occurred, through which the Company acquired 140 towers for approximately $26.2 million in cash.

 

2001 Acquisitions—During the year ended December 31, 2001, the Company consummated more than 30 transactions involving the acquisition of various communications sites and related businesses and satellite and fiber network access services assets for a purchase price of approximately of $ 827.2 million.

common stock valued at approximately $8.5 million and the assumption of certain liabilities. Total purchase price allocated to goodwill was approximately $30.7 million. The principal transaction was as follows:

 

ALLTEL transaction—In December 2000, the Company entered into an agreement to acquire the rights from ALLTEL to up to 2,193 communications towers through a fifteen-year sublease agreement. Under the agreement, the Company subleased these towers for cash consideration of up to $657.9 million. The Company has the option under the agreement to purchase the towers at the end of the fifteen-year term. The purchase price per tower will be $27,500 plus interest accrued at 3% per annum or 769 shares of the Company’s Class A common stock at ALLTEL’s option.

 

As of December 31, 2001, the Company subleased 1,748 towers and paid ALLTEL approximately $524.4 million in cash. In the first quarter of 2002, the Company closed on an additional 28 towers and paid ALLTEL approximately $8.4 million in cash. The Company will not close on the remaining 417 towers under the sublease agreement, as permitted by the agreement. The Company has accounted for the ALLTEL transaction as a capital lease.

 

2000 Acquisitions—During the year ended December 31, 2000, the Company consummated more than 60 transactions involving the acquisition of various communications sites and related businesses and several satellite and fiber network access services businesses for a purchase price of approximately of $1.8 billion. This purchase price includes approximately $1.4 billion in cash, the issuance of approximately 4.5 million shares of Class A common stock and options valued at approximately $164.0 million, warrants to purchase approximately  2.7 million shares of Class A common stock valued at $64.7 million and the assumption of $59.2 million of debt. Total purchase price allocated to goodwill was approximately $426.8 million. The principal transactions were as follows:

 

AirTouch transaction—In August 1999, the Company agreed to lease on a long-term basis (99 years) up to 2,100 towers located throughout the United States from AirTouch Communications, Inc. (now part of Verizon Wireless Inc.) (AirTouch). The Company’s cumulative lease payments, based on 2,100 towers, aggregate $800.0 million in cash payable in part upon each closing and the issuance of five-year warrants to purchase up to 3.0 million shares of Class A common stock at $22.00 per share. At various closings in 2000, the Company leased 1,801 towers, paid AirTouch approximately $686.1 million in cash and issued warrants to purchase approximately 2.7 million shares of its Class A common stock. In 2001, the Company leased 61 towers and paid AirTouch approximately $23.3 million in cash. The Company did not close on the balance of the towers included in the initial agreement. The Company has accounted for the AirTouch transaction as a purchase of assets.

 

AT&T transaction—In September 1999, the Company agreed to purchase up to 1,942 towers from AT&T. These towers are located throughout the United States and were constructed by AT&T for its microwave operations. The purchase price was $260.0 million in cash, subject to adjustment if all towers were not purchased. At various closings in 2000, the Company acquired 1,929 towers and paid AT&T $258.1 million. In 2001, the Company acquired two towers and paid AT&T approximately $0.1 million. The Company did not close on the balance of the towers included in the agreement.

 

During 2000, the Company had recorded a liability of approximately $2.0 million related primarily to contractual obligations assumed in its acquisition of towers from AT&T. During the years ended December 31, 2001 and 2000, the Company recorded charges of approximately $0.6 million and $0.8 million, respectively, against this liability. The Company reversed the remaining $0.6 million against other intangible assets as of December 31, 2001.

UNISite merger—In January 2000, the Company consummated its merger with UNISite, Inc. (UNISite). The purchase price was approximately $196.4 million, which included payment of $147.7 million in cash and the assumption of $48.7 million of debt. In February 2000, the Company repaid the debt assumed in connection with the UNISite transaction. (See note 7).

 

Discontinued Operations—During the year ended December 31, 2000, the Company consummated four transactions involving the acquisition of satellite and fiber network access services businesses for a purchase price of approximately $196.9 million. This purchase price includes approximately $97.9 million in cash and the issuance of approximately 2.6 million shares of Class A common stock and vested options to purchase 0.4 million shares of Class A common stock valued in aggregate at approximately $99.0 million.

 

In connection with one of these acquisitions, the Company recorded a liability of approximately $7.4 million related to contractual obligations assumed. During the years ended December 31, 2002 and 2001, the Company recorded charges against this liability of approximately $0.9 million and $0.8 million, respectively. In 2001, as a result of finalizing its purchase price allocation, the Company reversed approximately $3.8 million related to this liability against goodwill. In 2002, the Company reversed approximately $1.6 million related to this liability to loss from discontinued operations, net, in the accompanying consolidated statement of operations.The remaining balance related to this liability of $0.3 million as of December 31, 2002 is included in liabilities held for sale in the accompanying consolidated balance sheet.

 

Unaudited Pro Forma Operating Results—The unaudited pro forma results of operations for the years ended December 31, 2002 and 2001 are not presented due to the insignificant impact of the 2002 acquisitions (described above) on the Company’s consolidated results of operations.

16.    BUSINESS SEGMENTS

 

As of December 31, 2002, the Company operates in two business segments: rental and management (RM) and network development services (Services). The RM segment provides for the leasing and subleasing of antennae sites on multi-tenant towers and other properties for a diverse range of customers primarily in the wireless communication and broadcast industries. The Services segment offers a broad range of services, including antenna and line installation, maintenance, construction, site acquisition, zoning, radio frequency engineering, network design, tower monitoring and steel fabrication.

 

The accounting policies applied in compiling segment information below are similar to those described in note 1. In evaluating financial performance, management focuses on operating profit (loss), excluding depreciation and amortization, corporate general and administrative expense, restructuring expense, development expense and impairments and net loss on sale of long-lived assets. This measure of operating profit (loss) is also before interest income, interest expense, loss on investments and other expense, loss on term loan cancellation, note conversion expense, minority interest in net earnings of subsidiaries, income taxes, discontinued operations, extraordinary losses and cumulative effect of change in accounting principle. For reporting purposes the RM segment includes interest income, TV Azteca, net.

 

The Company’s reportable segments are strategic business units that offer different services. They are managed separately because each segment requires different resources, skill sets and marketing strategies. Summarized financial information concerning the Company’s reportable segments as of and for the years ended December 31, 2002, 2001 and 2000 is shown in the following tables. The “Other expenses” disclosure below represents amounts excluded from specific segments, such as depreciation and amortization, corporate and general administrative expense, restructuring expense, development expense, impairments and net loss on sale of long-lived assets, interest income, interest expense, loss on investments and other expense, loss on term loan cancellation, note conversion expense and minority interest in net earnings of subsidiaries. The total operating profit (loss) represents the Company’s loss from continuing operations before income taxes.

(1)   Effective January 1, 2002, the Company recognized a $562.6 million non-cash charge (net of a tax benefit of $14.4 million) as the cumulative effect of change in accounting principle related to the write-down of goodwill to its fair value. In accordance with SFAS No. 142, this charge is reflected in the quarter ended March 31, 2002.
(2)   During the third quarter 2002, the Company recognized a $84.6 million non-cash charge related to the write-down and sale of certain non-core towers and the write-off of construction-in-progress costs associated with approximately 800 towers that it no longer plans to build. The Company also recognized a $187.8 million non-cash charge related to the write-down of certain long-lived assets of Verestar, which is included in loss from discontinued operations, net.
(3)   During the fourth quarter 2001, the Company recognized a $62.6 million non-cash charge to write-off certain construction-in-progress costs associated with the abandonment of tower sites that the Company no longer intended to build.

19.    SUBSEQUENT EVENTS

 

12.25% Senior Subordinated Discount Notes and Warrants Offering—In January 2003, the Company issued 808,000 units, each consisting of (1) $1,000 principal amount at maturity of the 12.25% senior subordinated discount notes due 2008 of a wholly owned subsidiary of the Company (ATI Notes) and (2) a warrant to purchase 14.0953 shares of Class A common stock of the Company, for gross proceeds of $420.0 million. The gross offering proceeds were allocated between the ATI Notes ($367.4 million) and the fair value of the warrants ($52.6 million). Net proceeds from the offering aggregated approximately $397.0 million and were or will be used for the purposes described below under Amended and Restated Loan Agreement.

 

The ATI Notes accrue no cash interest. Instead, the accreted value of each ATI Note will increase between the date of original issuance and maturity (August 1, 2008) at a rate of 12.25% per annum. The 808,000 warrants that were issued together with the ATI Notes each represent the right to purchase 14.0953 shares of Class A common stock at $0.01 per share. The warrants are exercisable at any time on or after January 29, 2006 and will expire on August 1, 2008. As of the issuance date, the warrants represented approximately 5.5% of the Company’s outstanding common stock (assuming exercise of all warrants).

 

The indenture governing the ATI Notes contains covenants that, among other things, limit the ability of the issuer subsidiary and its guarantors to incur or guarantee additional indebtedness, create liens, pay dividends or make other equity distributions, enter into agreements restricting the restricted subsidiaries’ ability to pay dividends, purchase or redeem capital stock, make investments and sell assets or consolidate or merge with or into other companies. The ATI Notes rank junior in right of payment to all existing and future senior indebtedness, including all indebtedness outstanding under the credit facilities, and are structurally senior in right of payment to all existing and future indebtedness of the Company.

 

Amended and Restated Loan Agreement—On February 21, 2003, the Company completed an amendment to its credit facilities. The amendment provides for the following:

 

    Prepayment of a Portion of Outstanding Term Loans.    The Company agreed to prepay an aggregate of $200.0 million of the term loans outstanding under the credit facilities from a portion of the net proceeds of the ATI Notes offering completed in January 2003. This prepayment consisted of a $125.0 million prepayment of the term loan A and a $75.0 million prepayment of the term loan B, each to be applied to reduce future scheduled principal payments.

 

Giving effect to the prepayment of $200.0 million of term loans under the credit facility and the issuance of the ATI Notes as discussed above as well as the paydown of debt from net proceeds of the sale of MTN ($24.5 million in February 2003), the Company’s aggregate principal payments of long-term debt, including capital leases, for the next five years and thereafter are as follows (in thousands):

    Reduction to Revolving Loan Commitments.    The Company reduced its revolving credit facility by $225.0 million for a total commitment of $425.0 million.

 

    Consent for Restricted Payments to Prepay or Repurchase the 2.25% Notes.    The lenders under the credit facilities have agreed to permit the Company to make payments of up to $217.0 million, consisting of the balance of the net proceeds of the ATI Notes offering after prepayments of the term loans and cash on hand, to prepay or repurchase its 2.25% Notes. To the extent that the $217.0 million is not used or required to prepay or repurchase any of the 2.25% Notes, the Company may use any remaining proceeds through June 30, 2004 to prepay or repurchase any indebtedness of the Company. Pending these payments, the $217.0 million will be held in a restricted account that is pledged to the lenders and, to the extent the Company does not use the funds in the account for such payments by June 30, 2004, the Company must use the remaining funds to prepay a portion of the term loans outstanding under the credit facilities.

 

    Leverage Ratio.    The leverage ratio was amended to take into account the issuance of the ATI Notes and a new senior leverage ratio has been added.

 

    Revolving Credit Facility Drawdowns.    A provision has been added limiting future revolving credit facility drawdowns based on the Company’s cash on hand.

 

The primary condition for the release of the net proceeds of the ATI Notes, which have been maintained in an escrow account since the closing on the ATI Notes, has now been satisfied as a result of entering into the amendment described above. Such release will occur in the first quarter of 2003.

 

20.    SUBSIDIARY GUARANTEES

 

The Company’s payment obligations under the ATI Notes are fully and unconditionally guaranteed on joint and several bases by the Company’s parent and substantially all of the parent’s and ATI’s wholly owned domestic subsidiaries (collectively Restricted Guarantors). The ATI Notes and the subsidiary guarantees under the notes are subordinated to all indebtedness under the Company’s credit facilities.

 

The following condensed consolidating financial data illustrates the composition of the Company’s parent, the issuer of the ATI Notes (ATI), the combined guarantor subsidiaries under the ATI Notes and non-guarantor subsidiaries. These statements have been prepared in accordance with the rules and requirements of the Securities and Exchange Commission and the requirements contained in the ATI Notes indenture. The Company believes that separate complete financial statements of the respective guarantors would not provide additional material information which would be useful in assessing the financial composition of the guarantors. No single guarantor has any significant legal restrictions on the ability of investors or creditors to obtain access to its assets in event of default on the subsidiary guarantee other than its subordination to the Company’s credit facilities described above.

 

Investments in subsidiaries are accounted for by the parent under the equity method for purposes of the supplemental consolidating presentation. In addition, ATI and the guarantor subsidiaries account for their subsidiaries that are not guarantors under the equity method. (Earnings) losses of subsidiaries accounted for under the equity method are therefore reflected in their parents’ investment accounts. The principal elimination entries eliminate investments in subsidiaries and intercompany balances and transactions.

AMERICAN TOWER CORPORATION (a Delaware Corporation) BY-LAWS ARTICLE I OFFICES SECTION 1. Registered Office. The registered office of the Corporation shall be located in Wilmington, County of New Castle, State of Delaware, and the name of the resident agent in charge thereof shall be Corporation Service Company. SECTION 2. Other Offices. The Corporation may also have offices at such other places, within or without the State of Delaware, as the Board of Directors may from time to time appoint or the business of the Corporation may require. ARTICLE II SEAL The seal of the Corporation shall, subject to alteration by the Board of Directors, consist of a flat-faced circular die with the word "Delaware", together with the name of the Corporation and the year of incorporation, cut or engraved thereon. ARTICLE III MEETINGS OF STOCKHOLDERS SECTION 1. Place of Meeting. Meetings of the stockholders shall be held either within or without the State of Delaware at such place as the Board of Directors may fix from time to time. SECTION 2. Annual Meetings. The annual meeting of stockholders shall be held for the election of directors on such date and at such time as the Board of Directors may fix from time to time. Any other proper business may be transacted at the annual meeting. SECTION 3. Special Meetings. Special meetings of the stockholders for any purpose or purposes may be called by the Chairman of the Board of Directors, if there be one, the President or by the directors (either by written instrument signed by a majority or by resolution adopted by a vote of the majority), and special meetings shall be called by the President or the Secretary * As Amended Through February 26, 2003 -1-

whenever stockholders owning a majority of the capital stock issued, outstanding and entitled to vote so request in writing. Such request of stockholders shall state the purpose or purposes of the proposed meeting. SECTION 4. Notice. Written or printed notice of every meeting of stockholders, annual or special, stating the hour, date and place thereof, and the purpose or purposes in general terms for which the meeting is called shall, not less than ten (10) days, or such longer period as shall be provided by law, the Certificate of Incorporation, these By-Laws, or otherwise, and not more than sixty (60) days before such meeting, be served upon or mailed to each stockholder entitled to vote thereat, at the address of such stockholder as it appears upon the stock records of the Corporation or, if such stockholder shall have filed with the Secretary of the Corporation a written request that notices be mailed to some other address, then to the address designated in such request. Notice of the hour, date, place and purpose of any meeting of stockholders may be dispensed with if every stockholder entitled to vote thereat shall attend either in person or by proxy and shall not, at the beginning of the meeting, object to the holding of such meeting because the meeting has not been lawfully called or convened, or if every absent stockholder entitled to such notice shall in writing, filed with the records of the meeting, either before or after the holding thereof, waive such notice. SECTION 5. Quorum and Adjournments. Except as otherwise provided by law or by the Certificate of Incorporation, the presence in person or by proxy at any meeting of stockholders of the holders of a majority of the shares of the capital stock of the Corporation issued and outstanding and entitled to vote thereat, shall be requisite and shall constitute a quorum. So long as the Certificate of Incorporation provides for more or less than one vote for any share, or any matter, every reference in these By-Laws to a majority or other proportion of shares shall refer to such majority or other proportion of the votes of such shares. If two or more classes of stock are entitled to vote as separate classes upon any question, then, in the case of each such class, a quorum for the consideration of such question shall, except as otherwise provided by law or by the Certificate of Incorporation, consist of a majority in interest of all stock of that class issued, outstanding and entitled to vote. If a majority of the shares of capital stock of the Corporation issued and outstanding and entitled to vote thereat or, where a larger quorum is required, such quorum, shall not be represented at any meeting of the stockholders regularly called, the holders of a majority of the shares present or represented by proxy and entitled to vote thereat shall have power to adjourn the meeting to another time, or to another time and place, without notice other than announcement of adjournment at the meeting, and there may be successive adjournments for like cause and in like manner until the requisite amount of shares entitled to vote at such meeting shall be represented; provided, however, that if the adjournment is for more than thirty (30) days, notice of the hour, date and place of the adjourned meeting shall be given to each stockholder entitled to vote thereat. Subject to the requirements of law and the Certificate of Incorporation, on any issue on which two or more classes of stock are entitled to vote separately, no adjournment shall be taken with respect to any class for which a quorum is present unless the Chairman of the meeting otherwise directs. At any meeting held to consider matters which were subject to adjournment for want of a quorum at which the requisite amount of shares entitled to vote thereat shall be represented, any business may be transacted which might have been transacted at the meeting as originally noticed. * As Amended Through February 26, 2003 -2-

SECTION 6. Votes; Proxies. Except as otherwise provided in the Certificate of Incorporation, at each meeting of stockholders, every stockholder of record at the closing of the transfer books, if closed, or on the date set by the Board of Directors for the determination of stockholders entitled to vote at such meeting, shall have one vote for each share of stock entitled to vote which is registered in such stockholder's name on the books of the Corporation, and, in the election of directors, may vote cumulatively to the extent, if any, and in the manner authorized in the Certificate of Incorporation. Each stockholder of record entitled to vote at a meeting of stockholders may vote in person or may authorize another person or persons to vote for such stockholder by a proxy executed or transmitted in a manner permitted by the General Corporation Law of Delaware by the stockholder or such stockholder's authorized agent and delivered (including by electronic transmission) to the Secretary of the Corporation. No such proxy shall be voted upon after three years from the date of its execution, unless the proxy expressly provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or any interest in the Corporation generally. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing with the Secretary of the Corporation an instrument in writing or as otherwise permitted by law revoking the proxy or another duly executed proxy bearing a later date. Voting at meetings of stockholders need not be by written ballot and, except as otherwise provided by law, need not be conducted by an inspector of election unless so determined by the Chairman of the meeting or by the holders of shares of stock having a majority of the votes which could be cast by the holders of all outstanding shares of stock entitled to vote thereon which are present in person or represented by proxy at such meeting. If it is required or determined that an inspector of election be appointed, the Chairman shall appoint one inspector of election, who shall first take and subscribe an oath or affirmation faithfully to execute the duties of an inspector at such meeting with strict impartiality and according to the best of his ability. The inspectors so appointed shall take charge of the polls and, after the balloting, shall make a certificate of the result of the vote taken. No director or candidate for the office of director shall be appointed as such inspector. At any meeting at which a quorum is present, a plurality of the votes properly cast for election to fill any vacancy on the Board of Directors shall be sufficient to elect a candidate to fill such vacancy, and a majority of the votes properly cast upon any other question shall decide the question, except in any case where a larger vote is required by law, the Certificate of Incorporation, these By-Laws, or otherwise. SECTION 7. Organization. The Chairman of the Board, if there be one, or in his or her absence the Vice Chairman, or in the absence of a Vice Chairman, the President, or in the absence of the President, a Vice President, shall call meetings of the stockholders to order and shall act as chairman thereof. The Secretary of the Corporation, if present, shall act as secretary of all meetings of stockholders, and, in his or her absence, the presiding officer may appoint a secretary. * As Amended Through February 26, 2003 -3-

SECTION 8. Consent of Stockholders in Lieu of Meeting. Unless otherwise restricted by the Certificate of Incorporation, any action required or permitted by the Delaware General Corporation Law to be taken at any annual or special meeting of the stockholders of the Corporation, may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to its registered office in Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation's registered office shall be by hand or by certified or registered mail, return receipt requested. Every written consent shall bear the date of signature of each stockholder who signs the consent and no written consent shall be effective to take the corporate action referred to therein unless, within sixty (60) days of the earliest dated consent delivered in the manner required by this section to the Corporation, written consents signed by a sufficient number of stockholders to take action are delivered to the corporation by delivery to its registered office in Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation's registered office shall be by hand or by certified or registered mail, return receipt requested. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing. In the event that the action which is consented to is such as would have required the filing of a certificate under any section of the Delaware General Corporation Law other than Section 228 thereof, if such action had been voted on by stockholders at a meeting thereof, the certificate filed under such other section shall state, in lieu of any statement required by such section concerning any vote of stockholders, that written consent has been given in accordance with Section 228 of the Delaware General Corporation Law, and that written notice has been given as provided in such Section 228. ARTICLE IV DIRECTORS SECTION 1. Number. The business and affairs of the Corporation shall be conducted and managed by a Board of Directors consisting of not less than one director, none of whom needs to be a stockholder. The number of directors for each year shall be fixed at each annual meeting of stockholders, but if the number is not so fixed, the number shall remain as it stood immediately prior to such meeting. At each annual meeting of stockholders, the stockholders shall elect directors. Each director so elected shall hold office, subject to the provisions of law, the Certificate of Incorporation, these By-Laws, or otherwise, until the next annual meeting of stockholders or until his or her successor is elected and qualified. * As Amended Through February 26, 2003 -4-

At any time during any year, except as otherwise provided by law, the Certificate of Incorporation, these By-Laws, or otherwise, the number of directors may be increased or reduced, in each case by vote of a majority of the stock issued and outstanding and present in person or represented by proxy and entitled to vote for the election of directors or a majority of the directors in office at the time of such increase or decrease, regardless of whether such majority constitutes a quorum. SECTION 2. Term of Office. Each director shall hold office until the next annual meeting of stockholders and until his or her successor is duly elected and qualified or until his or her earlier death or resignation, subject to the right of the stockholders at any time to remove any director or directors as provided in Section 4 of this Article. SECTION 3. Vacancies. If any vacancy shall occur among the directors, or if the number of directors shall at any time be increased, the directors then in office, although less than a quorum, by a majority vote may fill the vacancies or newly- created directorships, or any such vacancies or newly-created directorships may be filled by the stockholders at any meeting. SECTION 4. Removal by Stockholders. Except as otherwise provided by law, the Certificate of Incorporation or otherwise, the holders of record of the capital stock of the Corporation entitled to vote for the election of directors may, by a majority vote, remove any director or directors, with or without cause, and, in their discretion, elect a new director or directors in place thereof. SECTION 5. Meetings. Meetings of the Board of Directors shall be held at such place, within or without the State of Delaware, as may from time to time be fixed by resolution of the Board of Directors or by the Chairman of the Board, if there be one, or by the President, and as may be specified in the notice or waiver of notice of any meeting. Meetings may be held at any time upon the call of the Chairman of the Board, if there be one, or the President or any two (2) of the directors in office by oral, telegraphic, telex, telecopy or other form of electronic transmission, or written notice, duly served or sent or mailed to each director not less than twenty-four (24) hours before such meeting, except that, if mailed, not less than seventy two (72) hours before such meeting. Meetings may be held at any time and place without notice if all the directors are present and do not object to the holding of such meeting for lack of proper notice or if those not present shall, in writing or by telegram, telex, telecopy or other form of electronic transmission, waive notice thereof. A regular meeting of the Board may be held without notice immediately following the annual meeting of stockholders at the place where such meeting is held. Regular meetings of the Board may also be held without notice at such time and place as shall from time to time be determined by resolution of the Board. Except as otherwise provided by law, the Certificate of Incorporation or otherwise, neither the business to be transacted at, nor the purpose of, any regular or special meeting of the Board of Directors or any committee thereof need be specified in any written waiver of notice. Members of the Board of Directors or any committee thereof may participate in a meeting of such Board or committee by means of conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear * As Amended Through February 26, 2003 -5-

each other and participation in a meeting pursuant to the foregoing provisions shall constitute presence in person at the meeting. SECTION 6. Votes. Except as otherwise provided by law, the Certificate of Incorporation or otherwise, the vote of the majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors.

Every certificate issued when the Corporation is authorized to issue more than one class or series of stock shall set forth on its face or back either the full text of the preferences, voting powers, qualifications, and special and relative rights of the shares of each class and series authorized to be issued, or a statement of the existence of such preferences, powers, qualifications and rights, and a statement that the Corporation will furnish a copy thereof to the holder of such certificate upon written request and without charge.

SECTION 4. Fixing Date for Determination of Stockholders of Record. In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or entitled to receive payment of any dividend or other distribution or * As Amended Through February 26, 2003 -12-

allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of directors and which record date: (a) in the case of determination of stockholders entitled to vote at any meeting of stockholders or adjournment thereof, shall, unless otherwise required by law, the Certificate of Incorporation or otherwise, not be more than sixty (60) nor less than ten (10) days before the date of such meeting; (b) in the case of determination of stockholders entitled to express consent to corporate action in writing without a meeting, shall, unless otherwise required by law, the Certificate of Incorporation or otherwise, not be more than ten (10) days from the date upon which the resolution fixing the record date is adopted by the Board of Directors; and (c) in the case of any other action, shall not be more than sixty (60) days prior to such other action. If no record date is fixed: (a) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; (b) the record date for determining stockholders entitled to express consent to corporate action in writing without a meeting when no prior action of the Board of Directors is required by law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation in accordance with applicable law, or, if prior action by the Board of Directors is required by law, shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action; and (c) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting. SECTION 5. Lost or Destroyed Certificates. In case of the loss or destruction of any certificate of stock, a new certificate may be issued under the following conditions: (a) The owner of said certificate shall file with the Secretary or any Assistant Secretary of the Corporation an affidavit giving the facts in relation to the ownership, and in relation to the loss or destruction of said certificate, stating its number and the number of shares represented thereby; such affidavit shall be in such form and contain such statements as shall satisfy the President, any Executive Vice President, Vice President, the Secretary, any Assistant Secretary, the Treasurer or any Assistant Treasurer, that said certificate has been accidentally destroyed or lost, and that a new certificate ought to be issued in lieu thereof. Upon being so satisfied, any such officer may require such owner to furnish the Corporation a bond in such penal sum and in such form as he or she may deem advisable, and with a surety or sureties approved by him or her, to indemnify and save harmless the Corporation from any claim, loss, damage or liability which may be occasioned by the issuance of a new certificate in lieu thereof. Upon such bond being so filed, if so required, a new certificate for the same number of shares shall be issued to the owner of the certificate so lost or destroyed; and the transfer agent and registrar, if any, of stock shall countersign and register such new certificate upon receipt of a written order signed by any such officer, and * As Amended Through February 26, 2003 -13-

thereupon the Corporation will save harmless said transfer agent and registrar in the premises. In case of the surrender of the original certificate, in lieu of which a new certificate has been issued, or the surrender of such new certificate, for cancellation, the bond of indemnity given as a condition of the issue of such new certificate may be surrendered; or (b) The Board of Directors of the Corporation may by resolution authorize and direct any transfer agent or registrar of stock of the Corporation to issue and register respectively from time to time without further action or approval by or on behalf of the Corporation new certificates of stock to replace certificates reported lost, stolen or destroyed upon receipt of an affidavit of loss and bond of indemnity in form and amount and with surety satisfactory to such transfer agent or registrar in each instance or upon such terms and conditions as the Board of Directors may determine.

ARTICLE XII INDEMNIFICATION SECTION 1. Indemnification. (a) The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any person who was or is a party or is threatened to be made a party or is otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Corporation) by reason of the fact that he, or a person for whom he is the legal representative, is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the Corporation as a director, officer, partner, member, trustee, employee or agent of another corporation, partnership, joint venture, limited liability company, trust or other enterprise or non-profit entity against all liability, losses, expenses (including attorneys' fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interest of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. (b) The Corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the Corporation, or is or was serving at the request of the * As Amended Through February 26, 2003 -16-

Corporation as a director, officer, partner, member, trustee, employee or agent of another corporation, partnership, joint venture, limited liability company, trust or other enterprise or non-profit entity against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the Corporation unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery of the State of Delaware or such other court shall deem proper. (c) To the extent that any person referred to in paragraphs (a) or (b) has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to therein, or in defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith. SECTION 2. Authorization. Any indemnification under Section 1 of this Article (unless ordered by a court) shall be made by the Corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, partner, member, trustee, employee or agent is proper in the circumstances because such person has met the applicable standard of conduct set forth in Section 1 of this Article. Such determination shall be made: (a) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (b) if such a quorum is not obtainable, or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in written opinion, or (c) by the stockholders.

The Corporation's obligation, if any, to indemnify any person who was or is serving at its request as a director, trustee, partner, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise or non-profit entity shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership, joint venture, trust or other enterprise or non-profit entity or from insurance.

The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. Section 4.06. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, 51

any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted. Section 4.07. Restricted Payments. The Company and each Sister Guarantor shall not, and each of them shall not permit any of their respective Restricted Subsidiaries to, directly or indirectly: (1) declare or pay any dividend or make any other payment or distribution on account of the Company's, any Sister Guarantor's or any of the Restricted Subsidiaries' Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company, any Sister Guarantor or any of the Restricted Subsidiaries) or to the direct or indirect holders of the Company's, any Sister Guarantor's or any of the Restricted Subsidiaries' Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Company or a Sister Guarantor or to the Company or a Sister Guarantor or a Restricted Subsidiary); (2) purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Company or a Sister Guarantor, as the case may be) any Equity Interests of the Company or a Sister Guarantor or of any Person of which the Company or a Sister Guarantor is a Subsidiary (other than any such Equity Interests owned by the Company, a Sister Guarantor or any of the Restricted Subsidiaries); (3) make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the Notes or the Note Guarantees, except a payment of interest or principal at the Stated Maturity thereof (other than payments to the Company or a Sister Guarantor or payments by a Restricted Subsidiary to the Company or a Sister Guarantor or to another Restricted Subsidiary); or (4) make any Restricted Investment, (all such payments and other actions set forth in these clauses (1) through (4) above, being collectively referred to as "Restricted Payments"), unless, at the time of and after giving effect to such Restricted Payment: 52

(1) no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; and (2) the Parent, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, would have had a Debt to Adjusted Consolidated Cash Flow Ratio no greater than 7.5 to 1.0; provided that this clause (2) shall not apply in connection with any Restricted Investment; and (3) such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company, the Sister Guarantors and the Restricted Subsidiaries after the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4) and (6)) of the next succeeding paragraph), is less than the sum, without duplication, of: (a) 100% of the Consolidated Cash Flow of the Parent for the period (taken as one accounting period) from the beginning of the fiscal quarter during which the Issue Date falls to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if the Consolidated Cash Flow for such period is a deficit, less 100% of the deficit), less 1.4 times the Consolidated Interest Expense of the Parent since the beginning of the fiscal quarter during which the Issue Date falls to the end of the Company's most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment, plus (b) (i) 100% of the aggregate net cash proceeds plus (ii) 70% of the aggregate value, as reflected on the balance sheets of the Company and the Sister Guarantors in accordance with GAAP using purchase accounting, of any Qualified Proceeds valued as of the date the Company's or a Sister Guarantor's Equity Interests were issued, sold or exchanged therefor, in each case, received by the Company or any Sister Guarantor since the Issue Date as a contribution to its common equity capital or from the issue, sale or exchange of Equity Interests of the Company and the Sister Guarantor (other than Disqualified Stock) or from the issue or sale (whether before or after the Issue Date) of Disqualified Stock or debt securities of the Company or any Sister Guarantor that have been converted after the Issue Date into Equity Interests (other than Equity Interests (or Disqualified Stock or 53

The preceding provisions shall not prohibit: (1) the payment of any dividend or the making of any distribution within 60 days after the date of declaration of the dividend or distribution, if at the date of declaration the dividend payment or distribution would have complied with the provisions of this Indenture; (2) (a) the making of any Investment or (b) the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness or Equity Interests of the Company or a Sister Guarantor, in the case of (a) or (b), in exchange for, or out of the net cash proceeds from 54

the substantially concurrent sale after the Issue Date (other than to a Subsidiary of the Company or a Sister Guarantor) of Equity Interests of the Company or of a Sister Guarantor (other than any Disqualified Stock); provided that, in each case, the amount of any net cash proceeds (or other assets, as applicable) that are so utilized shall be excluded from clause (3)(b) of the preceding paragraph; (3) the defeasance, redemption, repurchase or other acquisition of subordinated Indebtedness of the Company or any Group Guarantor with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; (4) the payment of any dividend by a Restricted Subsidiary to the holders of its Equity Interests on a pro rata basis; (5) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Parent, the Company, any Sister Guarantor or any Restricted Subsidiary held by any member of the Parent's, the Company's or any Sister Guarantor's (or any of the Restricted Subsidiaries') management pursuant to any management equity subscription agreement, stockholders agreement, stock option agreement or restricted stock agreement in effect as of the Issue Date; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $500,000 in any twelve-month period and $5.0 million in the aggregate since the Issue Date; and (6) any dividend, payment, advance or distribution made to the Parent, (i) which is applied by Parent to pay scheduled interest, dividends or principal or premium or liquidation preference at the Stated Maturity thereof or pursuant to a mandatory redemption or repurchase obligation on the Existing Parent Indebtedness or Additional Parent Indebtedness, (ii) in an amount equal to up to $217 million to be used for purposes described under the caption "Use of Proceeds" in the Offering Circular, or (iii) in accordance with clause (7) of the second paragraph of Section 4.11 hereof.

Not later than the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers' Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this 55

Section 4.07 were computed, together with a copy of any fairness opinion or appraisal required by this Indenture. Section 4.08. Dividend and Other Payment Restrictions Affecting Subsidiaries. The Company and each Sister Guarantor shall not, and shall not permit any of their respective Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to: (1) pay dividends or make any other distributions on its Capital Stock to the Company, any Sister Guarantor or any of the Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits; (2) pay any Indebtedness owed to the Company, any Sister Guarantor or any of the Restricted Subsidiaries; (3) make loans or advances to the Company, any Sister Guarantor or any of the Restricted Subsidiaries; or (4) transfer any of its properties or assets to the Company, any Sister Guarantor or any of the Restricted Subsidiaries. However, the preceding restrictions shall not apply to encumbrances or restrictions existing under or by reason of: (1) agreements governing Existing Indebtedness as in effect on the Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof, provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the Issue Date unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Company's Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding; (2) Indebtedness of the Company, any Sister Guarantor or any Restricted Subsidiary under any Credit Facility that is permitted to be incurred pursuant to Section 4.09 hereof; provided that such Credit Facility and Indebtedness contain only such encumbrances and restrictions on such Restricted Subsidiary's ability to engage in the activities set forth in clauses (1) through (4) of the preceding paragraph as are, at the time such Credit Facility is entered into or amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced, ordinary and 56

customary for a Credit Facility of that type as determined in the good faith judgment of the Company's Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding; (3) encumbrances and restrictions applicable to any Unrestricted Subsidiary, as the same are in effect as of the date on which the Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to the dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Company's Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding; (4) any Indebtedness incurred in compliance with Section 4.09 hereof or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in the Indebtedness or agreement and the encumbrance or restriction is not materially more disadvantageous to the Holders of the Notes than is customary in comparable financings (as determined by the Company) and the Company determines that any such encumbrance or restriction will not materially affect the Company's ability to pay the Accreted Value of the Notes; (5) this Indenture, the Notes and the Note Guarantees; (6) applicable law; (7) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company, any Sister Guarantor or any of the Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, and as such instrument may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Indenture to be incurred and, provided further, that any such amendment, modification, restatement, renewal, increase, supplement, 57

refunding, replacement or refinancing is no more restrictive, taken as a whole, with respect to the dividend and other payment restrictions than those contained in the instrument as in effect on the date on which the Person was acquired by the Company unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Company's Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding; (8) customary non-assignment provisions in leases or licenses entered into in the ordinary course of business; (9) purchase money obligations for property acquired in the ordinary course of business that impose restrictions of the nature described in clause (4) in the second paragraph of Section 4.09 hereof on the property so acquired; (10) any agreement for the sale or other disposition of a Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale or other disposition; (11) Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Company's Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding; (12) Liens permitted to be incurred pursuant to the provisions of Section 4.12 hereof that limit the right of the debtor to transfer the assets subject to such Liens; (13) provisions with respect to the disposition or distribution of assets or property in joint venture agreements and other similar agreements; and (14) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business. Section 4.09. Incurrence of Indebtedness and Issuance of Preferred Stock. The Company and each Sister Guarantor shall not, and shall not permit any of their respective Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, "incur") any Indebtedness (including Acquired Debt), and the Company and each Sister Guarantor shall not issue any Disqualified Stock and shall not permit any of their respective Restricted Subsidiaries to issue any shares of preferred stock. 58

The provisions of the first paragraph of this Section 4.09 shall not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, "Permitted Debt"): (1) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of Indebtedness under Credit Facilities in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company, the Sister Guarantors and the Restricted Subsidiaries thereunder) incurred under this clause (1) at any one time outstanding not to exceed $1.6 billion less any amount applied to reduce Indebtedness incurred under this clause (1) as a result of the operation of clause (1) of the second paragraph of Section 4.10 hereof; (2) the incurrence by the Company, the Sister Guarantors and the Restricted Subsidiaries of the Existing Indebtedness; (3) the incurrence by the Company and the Group Guarantors of Indebtedness represented by the Notes and the related Note Guarantees and the Exchange Notes and the related Note Guarantees to be issued pursuant to the Registration Rights Agreement; (4) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of Indebtedness: (a) represented by Capital Lease Obligations incurred (i) in connection with the lease or other use of space or time on satellites or (ii) for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment, in each case used in the Teleports Business of the Company, such Sister Guarantor or such Restricted Subsidiary or (b) represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company, such Sister Guarantor or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (4), not to exceed $50.0 million at any time outstanding; (5) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness (other than intercompany 59

Indebtedness) or preferred stock or Disqualified Stock that was permitted by this Indenture to be incurred under clauses (2), (3), (4), (5) or (11) of this paragraph; (6) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of intercompany Indebtedness between or among the Company, any Sister Guarantor and any of the Restricted Subsidiaries and the issuance by any Restricted Subsidiary of shares of preferred stock to the Company, a Sister Guarantor or to another Restricted Subsidiary; provided, however, that: (a) if the Company or any Group Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations with respect to the Notes, in the case of the Company, or the Note Guarantee, in the case of a Group Guarantor; and (b) (i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness or preferred stock being held by a Person other than the Company, a Sister Guarantor or a Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness or preferred stock to a Person that is not either the Company, a Sister Guarantor or a Restricted Subsidiary shall be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company, such Sister Guarantor or such Restricted Subsidiary or issuance of the shares of preferred stock by such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); (7) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of Hedging Obligations that are incurred for the purpose of fixing or hedging interest rate risk with respect to any floating rate Indebtedness that is permitted by the terms of this Indenture to be outstanding or currency exchange risk; (8) the Guarantee by the Company or any of the Group Guarantors of Indebtedness of the Company, a Sister Guarantor or a Restricted Subsidiary that was permitted to be incurred by another provision of this Indenture; (9) the accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock shall not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this Section 4.09; 60

provided, in each such case, that the amount thereof is included in Consolidated Interest Expense of the Company and the Sister Guarantors as accrued; (10) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of Acquired Debt in connection with a merger with or into a Restricted Subsidiary, or the acquisition of assets or a new Subsidiary; provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Company, a Sister Guarantor or one of the Restricted Subsidiaries and was not incurred in connection with, or in contemplation of, the acquisition by the Company, a Sister Guarantor or one of the Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this clause (10), as a result of such acquisition by the Company, a Sister Guarantor or one of the Restricted Subsidiaries, the Debt to Adjusted Consolidated Cash Flow Ratio of the Parent at the time of incurrence of such Acquired Debt, after giving pro forma effect to such acquisition and incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available, would have been the same or less than the Debt to Adjusted Consolidated Cash Flow Ratio of the Parent for the same period without giving pro forma effect to such incurrence; and (11) the incurrence by the Company, any Sister Guarantor or any of the Restricted Subsidiaries of additional Indebtedness and/or the issuance of preferred stock or Disqualified Stock in an aggregate principal amount (or accreted value or liquidation preference, as applicable) at any time outstanding, including Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (11), not to exceed $25.0 million. For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (11) above, the Company and the Sister Guarantors shall be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under the Credit Agreement outstanding on the date on which Notes are first issued and authenticated under this Indenture shall be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. Section 4.10. Asset Sales. The Company and each Sister Guarantor shall not, and shall not permit any of its respective Restricted Subsidiaries to, consummate an Asset Sale unless: 61

(1) the Company, Sister Guarantor or Restricted Subsidiary, as the case may be, receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of; (2) the fair market value is determined by the Company's Board of Directors and evidenced by a resolution of the Company's Board of Directors set forth in an Officers' Certificate delivered to the Trustee; and (3) except in the case of a Tower Asset Exchange, a Surplus Asset Sale or an Excluded International Sale, at least 75% of the consideration received in such Asset Sale by the Company, the Sister Guarantor or Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: (a) any liabilities of the Company, the Sister Guarantor or Restricted Subsidiary, as the case may be, as shown on its most recent balance sheet (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the transferee of any assets pursuant to a customary novation agreement that releases the Company, the Sister Guarantor or the Restricted Subsidiary from further liability; and (b) any securities, notes or other obligations received by the Company, the Sister Guarantor or the Restricted Subsidiary, as the case may be, from the transferee that are converted by the Company, the Sister Guarantor or the Restricted Subsidiary into cash within 20 days of the applicable Asset Sale, to the extent of the cash received in that conversion. Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company, the Sister Guarantor or the Restricted Subsidiary, as the case may be, may apply those Net Proceeds at its option: (1) to repay Senior Debt and, if the Senior Debt repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto; (2) to repay other Indebtedness of any of the Sister Guarantors or Restricted Subsidiaries; (3) to acquire all or substantially all of the assets of, or a majority of the Voting Stock or other Equity Interests of, another Permitted Business; (4) to make a capital expenditure; or (5) to acquire other assets that are used or useful in a Permitted Business. 62

Pending the final application of any Net Proceeds, they can be used to temporarily reduce revolving credit borrowings or otherwise be invested in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph shall constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall make an Asset Sale Offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount at maturity of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer for Notes shall be equal to 100% of the Accreted Value thereof and Liquidated Damages, if any, to the date of purchase, and shall be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, those Excess Proceeds may be used for any purpose not otherwise prohibited by this Indenture. If the aggregate Accreted Value of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds shall be reset to zero. Section 4.11. Transactions with Affiliates. The Company and each Sister Guarantor shall not, and shall not permit any of their respective Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate (each, an "Affiliate Transaction"), unless: (1) the Affiliate Transaction is on terms that, in the aggregate, are no less favorable to the Company, the relevant Sister Guarantor or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company, such Sister Guarantor or such Restricted Subsidiary with an unrelated Person; and (2) the Company delivers to the Trustee: (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million, an Officers' Certificate certifying that the Affiliate Transaction complies with clause (1) above; (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Company's Board of Directors set forth in an Officers' Certificate certifying that such Affiliate Transaction complies with clause (1) above and that such Affiliate 63

Transaction has been approved by a majority of the members of the Board of Directors of the Company having no personal stake in such Affiliate Transaction (or, if there are no such members, by all of the directors and by the procedure described in clause (c) below); and (c) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, other than a Permitted Investment, an opinion as to the fairness to the Company of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing. Notwithstanding the foregoing, the following items shall not be deemed to be Affiliate Transactions and, therefore, shall not be subject to the provisions of the prior paragraph: (1) any employment agreement entered into with any executive officer of the Company, any Sister Guarantor or any of the Restricted Subsidiaries that is entered into by the Company, any Sister Guarantor or any of the Restricted Subsidiaries in the ordinary course of business and substantially consistent with the compensation arrangements of similarly situated executive officers at comparable companies engaged in Permitted Businesses; (2) transactions between or among the Company, the Sister Guarantors and/or the Restricted Subsidiaries; (3) transactions with a Person that is an Affiliate of the Company or a Sister Guarantor or a Restricted Subsidiary solely because the Company or a Sister Guarantor or a Restricted Subsidiary owns an Equity Interest in, or controls, such Person; (4) payment of reasonable directors' fees to Persons in an aggregate annual amount per Person that is substantially consistent with directors' fees at comparable companies engaged in Permitted Businesses; (5) issuances or sales of Equity Interests (other than Disqualified Stock) of the Company; (6) transactions entered into in connection with the Escrow Corp. Merger; (7) payments to the Parent of customary tax sharing payments (including, without limitation, pursuant to the Tax Sharing Agreement) and of amounts necessary to pay Parent's reasonable and customary administrative and overhead expenses and reasonable transaction costs related to financings; 64

(8) arrangements between some or all of the Company, the Guarantors and the Restricted Subsidiaries, on the one hand, and Verestar or its Subsidiaries, on the other hand, in the ordinary course of business and in existence on the Issue Date; and (9) Restricted Payments that are permitted by Section 4.07 hereof and Permitted Investments. Section 4.12. Liens. The Company and each Sister Guarantor shall not, and shall not permit any of their respective Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing Indebtedness, Attributable Debt or trade payables (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured on an equal and ratable basis with the Obligations so secured until such time as such Obligations are no longer secured by a Lien. Section 4.13. Corporate Existence. Subject to Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect: (1) its corporate existence, and the corporate, partnership or other existence of each of its Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Subsidiary and (2) the rights (charter and statutory), licenses and franchises of the Company and its Subsidiaries; provided, however, that the Company shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if its Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes. Section 4.14. Offer to Repurchase Upon Change of Control. If a Change of Control occurs, the Company shall make an offer (a "Change of Control Offer") to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at a purchase price, in cash, equal to 101% of the Accreted Value of the Notes on the date of purchase plus Liquidated Damages, if any, on the Notes purchased, to the date of purchase (a "Change of Control Payment"). Within 15 days following any Change of Control, the Company shall mail a notice to each Holder describing the transaction or transactions that constitute a Change of Control and stating: 65

(1) that the Change of Control Offer is being made pursuant to this Section 4.14 and that all Notes tendered will be accepted for payment; (2) the purchase price and the purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the "Change of Control Payment Date"); (3) that any Note not tendered will continue to accrete interest; (4) that the Accreted Value of all Notes accepted for payment pursuant to the Change of Control Offer shall cease to increase after the Change of Control Payment Date; (5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount at maturity of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount at maturity to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $1,000 in principal amount at maturity or an integral multiple thereof; and (8) that Holders electing to have a Note purchased pursuant to a Change of Control Offer may elect to have Notes purchased in integral multiples of $1,000 only. On the Change of Control Payment Date, the Company shall, to the extent lawful, (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 66

(3) deliver or cause to be delivered to the Trustee the Notes so accepted together with an Officers' Certificate stating the aggregate principal amount at maturity of Notes or portions thereof being purchased by the Company. The Paying Agent shall promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in principal amount at maturity to any unpurchased portion of the Notes surrendered, if any; provided that each new Note shall be in a principal amount at maturity of $1,000 or an integral multiple of $1,000. The Change of Control provisions described above shall be applicable whether or not any other provisions of this Indenture are applicable. The Company shall comply with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations to the extent those laws and regulations are applicable to any Change of Control Offer. If the provisions of any of the applicable securities laws or securities regulations conflict with the provisions of this Section 4.14, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.14 by virtue of the compliance. The Company shall not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.14 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer. Section 4.15. Anti-Layering. The Company shall not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of the Company and senior in any respect in right of payment to the Notes. No Group Guarantor shall incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to the Senior Debt of such Group Guarantor and senior in any respect in right of payment to such Group Guarantor's Note Guarantee. Section 4.16. Sale and Leaseback Transactions. The Company and each Sister Guarantor shall not, and shall not permit any of their respective Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Company, any Sister Guarantor or any Restricted Subsidiary may enter into a sale and leaseback transaction if: (1) the Company, such Sister Guarantor or such Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction pursuant to the provisions of Section 4.09 hereof and (b) incurred a Lien to secure such Indebtedness pursuant to the provisions of Section 4.12 hereof; 67

(2) the gross cash proceeds of that sale and leaseback transaction are at least equal to the fair market value, as determined in good faith by the Board of Directors of the Company and set forth in an Officers' Certificate delivered to the Trustee, of the property that is the subject of that sale and leaseback transaction; and (3) the transfer of assets in that sale and leaseback transaction is permitted by, and the Company applies the proceeds of such transaction in compliance with, Section 4.10 hereof. Section 4.17. Covenant Suspension. If on any date following the Issue Date: (a) the Notes have an Investment Grade Rating and (b) no Default or Event of Default has occurred and is continuing under the Indenture, then, beginning on that day the Company, the Sister Guarantors and the Restricted Subsidiaries shall not be subject to the following Sections of this Indenture: Section 3.09, Section 4.07, Section 4.08, Section 4.09, Section 4.10, Section 4.11, Section 4.15, Section 4.19, clause (1)(a) of Section 4.16, the proviso to the last paragraph of the definition of "Unrestricted Subsidiary" in Section 1.01, and clause (4) of Section 5.01 (collectively, the "Suspended Covenants"). In the event the foregoing Sections are suspended pursuant to this Section 4.17 and the rating assigned by both Rating Agencies should subsequently decline to below an Investment Grade Rating, the foregoing Sections shall be reinstituted as of and from the date of such rating decline. Compliance with Section 4.07 hereof shall be calculated as if it had been in effect since the Issue Date except that no Default shall be deemed to have occurred solely by reason of a Restricted Payment made while that Section was suspended, and no other Default shall be deemed to have occurred with respect to the suspended Sections during the time they were suspended (or after that time based solely on events that occurred during that time). Section 4.18. Additional Subsidiary Note Guarantees. The Company and each Sister Guarantor shall cause any Person that shall become a Wholly Owned Domestic Restricted Subsidiary of the Company or the Sister Guarantor, as the case may be, after the consummation of the Escrow Corp. Merger to become a Guarantor and evidence its Note Guarantee by executing a supplemental indenture in the form of supplemental indenture attached as Exhibit B and deliver an Opinion of Counsel to the Trustee within ten Business Days of the date on which it was acquired and created to the effect that such supplemental indenture has been duly authorized, executed and delivered by that Wholly Owned Domestic Restricted Subsidiary, and is enforceable in accordance with its terms (subject to customary exceptions); provided that this Section 4.18 does not apply to any Subsidiaries of the Company or any Group Guarantor that have properly been designated as Unrestricted 68

Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Section 4.19. Designation of Restricted and Unrestricted Subsidiaries. The Board of Directors of the Company may designate any Restricted Subsidiary of the Company or of a Sister Guarantor to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Company, the Sister Guarantors and the Restricted Subsidiaries in the Subsidiary properly designated shall be deemed to be an Investment made as of the time of the designation and shall reduce the amount available for Restricted Payments under Section 4.07 hereof or Permitted Investments, as determined by the Company. That designation shall only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Company or a Sister Guarantor may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary as provided in the last paragraph of the definition thereof. ARTICLE 5 SUCCESSORS Section 5.01. Merger, Consolidation, or Sale of Assets. The Company shall not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not the Company is the surviving corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of the Company and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless: (1) either: (a) the Company is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Company) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation organized or existing under the laws of the United States, any state of the United States or the District of Columbia; (2) the Person formed by or surviving any such consolidation or merger (if other than the Company) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the Obligations of the Company under the Notes, this Indenture and the Registration Rights Agreement pursuant to agreements reasonably satisfactory to the Trustee; (3) immediately after such transaction, no Default or Event of Default exists; and 69

(4) except in the case of (A) a merger of the Company with or into a Wholly Owned Restricted Subsidiary of the Company, a Sister Guarantor or a Wholly Owned Restricted Subsidiary of a Sister Guarantor, (B) a merger entered into solely for the purpose of reincorporating the Company in another jurisdiction and (C) the Escrow Corp. Merger: (x) in the case of a merger or consolidation in which the Company is the surviving corporation, the Parent, at the time of the transaction, after giving pro forma effect to the transaction as of such date for balance sheet purposes and as if the transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of the Company for which internal financial statements are available for income statement purposes, (i) would have had a Debt to Adjusted Consolidated Cash Flow Ratio no greater than 7.5 to 1.0 or (ii) would have had a Debt to Adjusted Consolidated Cash Flow Ratio that was not greater than its Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction, or (y) in the case of any other such transaction, the entity or Person formed by or surviving any such consolidation or merger (if other than the Company), or to which the sale, assignment, transfer, conveyance or other disposition shall have been made, at the time of the transaction, after giving pro forma effect to the transaction as of such date for balance sheet purposes and as if such transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of such entity or Person for which internal financial statements are available for income statement purposes, (i) would have had a Debt to Adjusted Consolidated Cash Flow Ratio no greater than 7.5 to 1.0 or (ii) would have had a Debt to Adjusted Consolidated Cash Flow Ratio that was not greater than the Debt to Adjusted Consolidated Cash Flow Ratio of the Parent for the same period without giving pro forma effect to such transaction. In addition, the Company shall not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person. This Section 5.01 not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among the Company and any of the Guarantors. Section 5.02. Successor Corporation Substituted. Upon any consolidation or merger, or any sale, assignment, transfer, conveyance or other disposition of all or substantially all of the assets of the Company in accordance with Section 5.01 hereof, the successor corporation formed by such consolidation or into or with which the Company is merged or to which such sale, assignment, transfer, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, conveyance or other disposition, the provisions of this Indenture 70

referring to the "Company" shall refer instead to the successor corporation and not to the Company), and may exercise every right and power of the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein; provided, however, that the predecessor Company shall not be relieved from the obligation to pay the Accreted Value of the Notes except in the case of a sale of all of the Company's assets that meets the requirements of Section 5.01 hereof. ARTICLE 6 DEFAULTS AND REMEDIES Section 6.01. Events of Default.

and, in each case referred to in clauses (a) and (b) above, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more; (6) failure by the Company or any of its Significant Subsidiaries to pay final judgments aggregating in excess of $20.0 million, which judgments are not paid, discharged or stayed for a period of 60 days; (7) except as permitted by this Indenture, any Note Guarantee by any Significant Subsidiary of the Company shall be held in final and non-appealable judgment to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any such Guarantor that is a Significant Subsidiary of the Company, or any Person acting on behalf of any such Guarantor, shall in writing deny or disaffirm its obligations under its Note Guarantee; (8) failure by the Company to effect the mandatory redemption of the Notes as provided for in Section 3.08 hereof, and (9) the Company or any of its Significant Subsidiaries pursuant to or within the meaning of Bankruptcy Law: (a) commences a voluntary case, (b) consents to the entry of an order for relief against it in an involuntary case, (c) consents to the appointment of a custodian of it or for all or substantially all of its property, (d) makes a general assignment for the benefit of its creditors, or (e) generally is not paying its debts as they become due; or (10) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (a) is for relief against the Company or any of its Significant Subsidiaries in an involuntary case; (b) appoints a custodian of the Company or any of its Significant Subsidiaries or for all or substantially all of the property of the Company or any of its Significant Subsidiaries; or 72

(c) orders the liquidation of the Company or any of its Significant Subsidiaries; and the order or decree remains unstayed and in effect for 60 consecutive days. Section 6.02. Acceleration. In the case of an Event of Default specified in clause (9) or (10) of Section 6.01 hereof, with respect to the Company or any Restricted Subsidiary that is a Significant Subsidiary, all outstanding Notes shall become due and payable immediately in an amount equal to the Accreted Value of the Notes outstanding on the date of acceleration, without further action or notice. If any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal at maturity of the then outstanding Notes may declare all the Notes to be due and payable immediately in an amount equal to the Accreted Value of the Notes outstanding on the date of acceleration. Upon any such declaration, the Accreted Value of the Notes outstanding on the date of acceleration shall become immediately due and payable. Section 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of Accreted Value of, Liquidated Damages and premium, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law. Section 6.04. Waiver of Past Defaults. Holders of not less than a majority in aggregate principal amount at maturity of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the Accreted Value of, and Liquidated Damages and premium, if any, on the Notes (including in connection with an offer to purchase) (provided, however, that the Holders of a majority in aggregate principal amount at maturity of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration). Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon. 73

Section 6.05. Control by Majority. Holders of a majority in principal amount at maturity of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. Section 6.06. Limitation on Suits. A Holder of a Note may pursue a remedy with respect to this Indenture or the Notes only if: (1) the Holder of a Note gives to the Trustee written notice of a continuing Event of Default; (2) the Holders of at least 25% in principal amount at maturity of the then outstanding Notes make a written request to the Trustee to pursue the remedy; (3) such Holder of a Note or Holders of Notes offer and, if requested, provide to the Trustee indemnity satisfactory to the Trustee against any loss, liability or expense; (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer and, if requested, the provision of indemnity; and (5) during such 60-day period the Holders of a majority in principal amount at maturity of the then outstanding Notes do not give the Trustee a direction inconsistent with the request. A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. Section 6.07. Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of Accreted Value, Liquidated Damages and premium, if any, on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 74

Section 6.08. Collection Suit by Trustee. If an Event of Default specified in clauses (1) or (2) of Section 6.01 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company for the whole amount of Accreted Value, Liquidated Damages and premium, if any, remaining unpaid on the Notes and interest on overdue Accreted Value, to the extent lawful, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. Section 6.09. Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. Section 6.10. Priorities. If the Trustee collects any money pursuant to this Article, it shall pay out the money in the following order: First: to the Trustee, its agents and attorneys for amounts due under Section 7.07 hereof, including payment of all compensation, expense and liabilities incurred, and all advances made, by the Trustee and the costs and expenses of collection; Second: to Holders of Notes for amounts due and unpaid on the Notes for Accreted Value, Liquidated Damages and premium, if any, ratably, without preference or priority 75

of any kind, according to the amounts due and payable on the Notes for Accreted Value, Liquidated Damages and premium, if any, respectively; and Third: to the Company or to such party as a court of competent jurisdiction shall direct. The Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10. Section 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in principal amount at maturity of the then outstanding Notes. ARTICLE 7 TRUSTEE Section 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person's own affairs. (b) Except during the continuance of an Event of Default: (i) the duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the certificates and opinions required to be furnished to the Trustee hereunder to determine whether or not they conform to the requirements of this Indenture. 76

(c) The Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (i) this paragraph does not limit the effect of paragraph (b) of this Section 7.01; (ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and (iii) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05 hereof. (d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b), and (c) of this Section 7.01. (e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder shall have offered to the Trustee security and indemnity satisfactory to it against any loss, liability or expense. (f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. Section 7.02. Rights of Trustee. (a) The Trustee may conclusively rely upon any document (whether in its original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document. (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officers' Certificate or Opinion of Counsel.

(c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. 77

(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient if signed by an Officer of the Company. (f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction. Section 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee or resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. Section 7.04. Trustee's Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture or the Notes, it shall not be accountable for the Company's use of the proceeds from the Notes or any money paid to the Company or upon the Company's direction under any provision of this Indenture, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it shall not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its certificate of authentication. Section 7.05. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if it is actually known to a Responsible Officer of the Trustee, the Trustee shall mail to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except a Default or Event of Default relating to the payment of Accreted Value of, or Liquidated Damages on, the Notes, the Trustee may withhold the notice if and so long as a committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. Section 7.06. Reports by Trustee to Holders of the Notes. Within 60 days after each May 15 beginning with the May 15 following the Issue Date, and for so long as Notes remain outstanding, the Trustee shall mail to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, 78

no report need be transmitted). The Trustee also shall comply with TIA Section 313(b). The Trustee shall also transmit by mail all reports as required by TIA Section 313(c). A copy of each report at the time of its mailing to the Holders of Notes shall be mailed to the Company and filed with the SEC and each stock exchange on which the Notes are listed in accordance with TIA Section 313(d). The Company shall promptly notify the Trustee when the Notes are listed on any stock exchange or delisted therefrom. Section 7.07. Compensation and Indemnity. The Company shall pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and services hereunder. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel. The Company shall fully indemnify the Trustee against any and all losses, liabilities, claims, damages or expenses (including legal fees and expenses) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense is caused by its own negligence or willful misconduct. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The obligations of the Company under this Section 7.07 shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee. To secure the Company's payment obligations in this Section 7.07, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay Accreted Value on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture. When the Trustee incurs expenses or renders services after an Event of Default specified in clauses (9) or (10) of Section 6.01 hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law. The Trustee shall comply with the provisions of TIA Section 313(b)(2) to the extent applicable. 79

Section 7.08. Replacement of Trustee. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section. The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Company. The Holders of a majority in principal amount at maturity of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Company in writing. The Company may remove the Trustee if: (a) the Trustee fails to comply with Section 7.10 hereof; (b) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law; (c) a custodian or public officer takes charge of the Trustee or its property; or (d) the Trustee becomes incapable of acting. If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount at maturity of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee appointed by the Company. If a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company, or the Holders of at least 10% in principal amount at maturity of the then outstanding Notes may petition at the expense of the Company any court of competent jurisdiction for the appointment of a successor Trustee. If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.10, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in Section 7.07 hereof. 80

Section 7.09. Successor Trustee by Merger, etc. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the successor corporation without any further act shall be the successor Trustee. Section 7.10. Eligibility; Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $75.0 million as set forth in its most recent published annual report of condition. This Indenture shall always have a Trustee who satisfies the requirements of TIA Section 310(a)(1), (2) and (5). The Trustee is subject to TIA Section 310(b). Section 7.11. Preferential Collection of Claims Against Company. The Trustee is subject to TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. Section 7.12. Trustee's Application for Instructions from the Company. Any application by the Trustee for written instructions from the Company may, at the option of the Trustee, set forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and the date on and/or after which such action shall be taken or such omission shall be effective. The Trustee shall not be liable for any action taken by, or omission of, the Trustee in accordance with a proposal included in such application on or after the date specified in such application (which date shall not be less than three Business Days after the date any officer of the Company actually receives such application, unless any such officer shall have consented in writing to any earlier date) unless prior to taking any such action (or the effective date in the case of an omission), the Trustee shall have received written instructions in response to such application specifying the action to be taken or omitted. ARTICLE 8 LEGAL DEFEASANCE AND COVENANT DEFEASANCE Section 8.01. Option to Effect Legal Defeasance or Covenant Defeasance. The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers' Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8. 81

Section 8.02. Legal Defeasance and Discharge. Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, "Legal Defeasance"). For this purpose, Legal Defeasance means that the Company and the Guarantors shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which shall thereafter be deemed to be "outstanding" only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments provided to it acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (1) the rights of Holders of outstanding Notes to receive payments in respect of the Accreted Value of, or premium and Liquidated Damages, if any, on such Notes when such payments are due from the trust referred to in Section 8.04 hereof; (2) the Company's obligations with respect to such Notes under Article 2 and Section 4.02 hereof; (3) the rights, powers, trusts, duties and immunities of the Trustee, and the Company's and the Guarantor's obligations in connection therewith; and (4) this Article 8. Subject to compliance with this Article 8, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 hereof. Section 8.03. Covenant Defeasance. Upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Company and the Group Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under the covenants contained in Sections 3.09, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.14, 4.15, 4.16, 4.17, 4.18 and 4.19 hereof and clause 4 of Section 5.01 hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, "Covenant Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Company and the Guarantors may omit to comply 82

with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees shall be unaffected thereby. In addition, upon the Company's exercise under Section 8.01 hereof of the option applicable to this Section 8.03 hereof, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, clauses (3) through (8) of Sections 6.01 hereof shall not constitute Events of Default. Section 8.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to the application of either Section 8.02 or 8.03 hereof to the outstanding Notes: In order to exercise either Legal Defeasance or Covenant Defeasance: (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in United States dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the Accreted Value of, Liquidated Damages or premium, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company shall specify whether the Notes are being defeased to maturity or to a particular redemption date; (2) in the case of an election under Section 8.02 hereof, the Company has delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that (a) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the Issue Date, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (3) in the case of an election under Section 8.03 hereof, the Company shall have delivered to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 83

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) (5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than this Indenture) to which the Company, any Sister Guarantor or any of the Restricted Subsidiaries is a party or by which the Company, any Sister Guarantor or any of the Restricted Subsidiaries is bound; (6) the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that on the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally; (7) the Company shall have delivered to the Trustee an Officers' Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any other creditors of the Company or others; and (8) the Company shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance have been complied with. Section 8.05. Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the "Trustee") pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of Accreted Value, Liquidated Damages and premium, if any, but such money need not be segregated from other funds except to the extent required by law. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 8.04 hereof or the Accreted Value, Liquidated Damages and premium, if any, received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 84

Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under clause (1) of Section 8.04 hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. Section 8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the Accreted Value, Liquidated Interest or premium, if any, on any Note and remaining unclaimed for two years after such Accreted Value, Liquidated Damages and premium, if any, has become due and payable shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Company. Section 8.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company's and each Guarantor's obligations under this Indenture and the Notes and the Note Guarantees shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Company makes any payment of Accreted Value of, Liquidated Damages or premium, if any, on any Note following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent. 85

ARTICLE 9 AMENDMENT, SUPPLEMENT AND WAIVER Section 9.01. Without Consent of Holders of Notes. Notwithstanding Section 9.02 of this Indenture, the Company, the Guarantors and the Trustee may amend or supplement this Indenture, the Note Guarantees or the Notes without the consent of any Holder of Notes: (1) to cure any ambiguity, defect or inconsistency; (2) to provide for uncertificated Notes in addition to or in place of certificated Notes or to alter the provisions of Article 2 hereof (including the related definitions) in a manner that does not materially adversely affect any Holder; (3) to provide for the assumption of the Company's obligations to the Holders of the Notes by a successor to the Company pursuant to Article 5 hereof; (4) to make any change that would provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under this Indenture of any such Holder; (5) to comply with requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; or (6) to conform the text of this Indenture, the Note Guarantees or the Notes to any provision of the Description of Notes in the Offering Circular to the extent that such provision in such Description of Notes was intended to be a verbatim recitation of a provision of this Indenture, the Note Guarantees or the Notes. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental indenture, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of any amended or supplemental indenture authorized or permitted by the terms of this Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee shall not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this Indenture or otherwise. Section 9.02. With Consent of Holders of Notes. Except as provided below in this Section 9.02, the Company and the Trustee may amend or supplement this Indenture (including Section 3.09, 4.10 and 4.14 hereof), the Note Guarantees 86

and the Notes with the consent of the Holders of at least a majority in aggregate principal amount at maturity of the Notes then outstanding, voting as a single class, (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than an uncured Default or Event of Default in the payment of the Accreted Value of, premium or Liquidated Damages, if any, on the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture, the Note Guarantees or the Notes may be waived with the consent of the Holders of a majority in aggregate principal amount at maturity of the then outstanding Notes, voting as a single class, (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes). Without the consent of at least 66?% in aggregate principal amount at maturity of the Notes then outstanding (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes), no waiver or amendment to this Indenture may make any change in the provisions of Article 11 hereof that adversely affects the rights of any Holder of the Notes. Section 2.08 hereof shall determine which Notes are considered to be "outstanding" for purposes of this Section 9.02. Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in Section 7.02 hereof, the Trustee shall join with the Company in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. It shall not be necessary for the consent of the Holders of Notes under this Section 9.02 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such amended or supplemental Indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount at maturity of the Notes then outstanding, voting as a single class, may waive compliance in a particular instance by the Company and the Group Guarantors with any provision of this Indenture, the Note Guarantees or the Notes. However, without the consent of each Holder affected, an amendment or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder): (1) reduce the principal amount at maturity of Notes whose Holders must consent to an amendment, supplement or waiver; 87

(2) reduce the principal amount at maturity of or change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes, except as provided above with respect to Sections 3.09, 4.10 and 4.14 hereof, or amend or modify the calculation of Accreted Value so as to reduce the amount of the Accreted Value of the Notes; (3) waive a Default or Event of Default in the payment of the Accreted Value of, or premium, or Liquidated Damages, if any, on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount at maturity of the Notes then outstanding and a waiver of the payment default that resulted from such acceleration); (4) make any Note payable in money other than that stated in the Notes; (5) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of the Accreted Value of, or premium or Liquidated Damages, if any, on the Notes; (6) waive a redemption payment except as provided above with respect to Sections 3.09, 4.10 or 4.14 hereof; (7) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or (8) make any change in Section 6.04 or 6.07 hereof or in the foregoing amendment and waiver provisions. Section 9.03. Compliance with Trust Indenture Act. Every amendment or supplement to this Indenture or the Notes shall be set forth in a amended or supplemental indenture that complies with the TIA as then in effect. Section 9.04. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 88

Section 9.05. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver. Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver. Section 9.06. Trustee to Sign Amendments, etc. The Trustee shall sign any amended or supplemental Indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amendment or supplemental indenture until the Board of Directors approves it. In executing any amended or supplemental indenture, the Trustee shall be entitled to receive and (subject to Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 13.04 hereof, an Officer's Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. ARTICLE 10 NOTE GUARANTEES Section 10.01. Guarantee. The provisions of this Article 10 shall apply only to (i) the Guarantors listed on the signature pages hereto upon the consummation of the Escrow Corp. Merger and (ii) with respect to any future Wholly Owned Domestic Restricted Subsidiaries of the Company or of any of the Sister Guarantors, if any, upon the execution of one or more supplemental indentures to this Indenture in the form of Exhibit C to this Indenture in compliance with the requirements of Section 4.18 of this Indenture. Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the Obligations of the Company hereunder or thereunder, that: (a) the Accreted Value of, and Liquidated Damages, if any, on, the Notes shall be promptly paid in full when due, whether at maturity, by acceleration, redemption or otherwise, and all other Obligations of the Company to the Holders or the Trustee hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (b) in case of any extension of time of payment or renewal of any Notes or any of such other Obligations, that same shall be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for 89

whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. The Guarantors hereby agree that their obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Note Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture. If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. Section 10.02. Subordination of Note Guarantee The Obligations of each Guarantor under its Note Guarantee pursuant to this Article 10 shall be subordinated to the Senior Debt of such Guarantor on the same basis as the Notes are subordinated to Senior Debt of the Company. Section 10.03. Limitation on Guarantor Liability. Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the 90

extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor shall not exceed an amount that, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, would result in the obligations of such Guarantor under its Note Guarantee constituting a fraudulent transfer or conveyance. Section 10.04. Evidence of Note Guarantee. To evidence its Note Guarantee set forth in Section 10.01, each Guarantor hereby agrees to execute this Indenture with effect as of the consummation of the Escrow Corp. Merger or, in the case of a Person becoming a Guarantor pursuant to Section 4.18 hereof, to execute a supplemental indenture in the form attached as Exhibit B. Section 10.05. Guarantors May Consolidate, etc., on Certain Terms. Except as otherwise provided in Section 10.06, no Group Guarantor may sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person other than the Company or another Group Guarantor, unless: (1) subject to Section 10.06 hereof, either (i) the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger unconditionally assumes all the Obligations of that Group Guarantor, pursuant to a supplemental indenture in the form attached as Exhibit B, under the Notes, the Indenture, the Note Guarantee and the Registration Rights Agreement on the terms set forth herein or therein or (ii) the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of this Indenture; and (2) immediately after giving effect to such transaction, no Default or Event of Default exists. In case of any such consolidation or merger and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee in the form attached as Exhibit B and the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person shall succeed to and be substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. All the Note Guarantees so issued shall in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as though all of such Note Guarantees had been issued at the date of the execution hereof. 91

Except as set forth in Articles 4 and 5 hereof, and notwithstanding clauses (1) and (2) above, nothing contained in this Indenture or in any of the Notes shall prevent any consolidation or merger of a Guarantor with or into the Company or another Guarantor, or shall prevent any sale or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Company or another Guarantor. Section 10.06. Releases. The Note Guarantee of a Group Guarantor shall be released: (1) in connection with any sale or other disposition of all or substantially all of the assets of that Group Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company, a Sister Guarantor or a Restricted Subsidiary, if the sale or other disposition complies with Section 4.10 hereof; (2) in connection with any sale of Capital Stock of a Group Guarantor (as a result of which such Guarantor is no longer a Subsidiary of the Company or a Subsidiary of a Sister Guarantor or, in the case of the Sister Guarantors, a Subsidiary of the Parent) to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Company or a Subsidiary of a Sister Guarantor or, in the case of the Sister Guarantors, a Subsidiary of the Parent, if the sale complies with Section 4.10 hereof and, if not a sale of all such Capital Stock, the remaining Investment of the Company, the Sister Guarantors and the Restricted Subsidiaries in such Group Guarantor complies with Section 4.07 hereof; (3) if the Company or a Sister Guarantor designates such Group Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of this Indenture; or (4) if such Group Guarantor is released from its Guarantee under the Credit Agreement or is released from its obligations as a co-borrower under the Credit Agreement. Any Guarantor not released from its obligations under its Note Guarantee shall remain liable for the Accreted Value of the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10. The Note Guarantee of the Parent shall be released if the Parent is released from its Guarantee under the Credit Agreement. If a Sister Guarantor is released from its Note Guarantee, it shall also be released from all of its Obligations under this Indenture. If any Group Guarantor is released from its Note Guarantee, its Restricted Subsidiaries shall also be released from their Note Guarantees. 92

ARTICLE 11 SUBORDINATION Section 11.01. Agreement to Subordinate. The Company agrees, and each Holder by accepting a Note agrees, that the Indebtedness evidenced by the Notes is subordinated in right of payment, to the extent and in the manner provided in this Article 11, to the prior payment in full of all Senior Debt (whether outstanding on the date hereof or hereafter created, incurred, assumed or guaranteed), and that the subordination is for the benefit of the holders of Senior Debt. Section 11.02. Liquidation; Dissolution; Bankruptcy. Upon any distribution to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, in an assignment for the benefit of the Company's creditors or any marshaling of the Company's assets and liabilities: (1) holders of Senior Debt shall be entitled to receive payment in full of all Obligations due in respect of such Senior Debt (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt) before the Holders of Notes shall be entitled to receive any payment with respect to the Notes (except that Holders of Notes may receive and retain Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof); and (2) until all Obligations with respect to Senior Debt (as provided in clause (1) above) are paid in full, any distribution to which Holders would be entitled but for this Article 11 shall be made to holders of Senior Debt (except that Holders of Notes may receive and retain Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof), as their interests may appear. Section 11.03. Default on Designated Senior Debt. (a) The Company may not make any payment or distribution to the Trustee or any Holder in respect of Obligations with respect to the Notes and may not acquire from the Trustee or any Holder any Notes for cash or property (other than Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof) until all principal and other Obligations with respect to the Senior Debt have been paid in full if: (1) a payment default on Designated Senior Debt occurs and is continuing beyond any applicable grace period in the agreement, 93

indenture or other document governing such Designated Senior Debt; or (2) any other default occurs and is continuing on any series of Designated Senior Debt that permits holders of that series of Designated Senior Debt to accelerate its maturity and the Trustee receives a notice of such default (a "Payment Blockage Notice") from the Company or the holders of any Designated Senior Debt or their Representative. If the Trustee receives any such Payment Blockage Notice, no subsequent Payment Blockage Notice shall be effective for purposes of this Section unless and until (A) at least 360 days have elapsed since the effectiveness of the immediately prior Payment Blockage Notice and (B) all scheduled payments of Accreted Value, Liquidated Damages and premium, if any, on the Notes that have come due have been paid in full in cash. No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the Trustee may be, or may be made, the basis for a subsequent Payment Blockage Notice unless such default has been cured or waived for a period of not less than 180 days. (b) The Company may and shall resume payments on and distributions in respect of the Notes and may acquire them upon the earlier of: (1) in the case of a payment default, upon the date upon which such default is cured or waived, or (2) in the case of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived or 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated, if this Article 11 otherwise permits the payment, distribution or acquisition at the time of such payment or acquisition. Section 11.04. Acceleration of Notes. If payment of the Notes is accelerated because of an Event of Default, the Company shall promptly notify holders of Senior Debt of the acceleration. Section 11.05. When Distribution Must Be Paid Over. In the event that the Trustee or any Holder receives any payment of any Obligations with respect to the Notes (other than Permitted Junior Securities and payments made from any defeasance trust created pursuant to Section 8.01 hereof) at a time when the Trustee or such 94

Holder, as applicable, has actual knowledge that such payment is prohibited by Section 11.03 hereof, such payment shall be held by the Trustee or such Holder, in trust for the benefit of, and shall be paid forthwith over and delivered, upon written request, to, the holders of Senior Debt as their interests may appear or their Representative under the agreement, indenture or other document (if any) pursuant to which Senior Debt may have been issued, as their respective interests may appear, for application to the payment of all Obligations with respect to Senior Debt remaining unpaid to the extent necessary to pay such Obligations in full in accordance with their terms, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt. With respect to the holders of Senior Debt, the Trustee undertakes to perform only those obligations on the part of the Trustee as are specifically set forth in this Article 11, and no implied covenants or obligations with respect to the holders of Senior Debt shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt, and shall not be liable to any such holders if the Trustee pays over or distributes to or on behalf of Holders or the Company or any other Person money or assets to which any holders of Senior Debt are then entitled by virtue of this Article 11, except if such payment is made as a result of the willful misconduct or gross negligence of the Trustee. Section 11.06. Notice by Company The Company shall promptly notify the Trustee and the Paying Agent of any facts known to the Company that would cause a payment of any Obligations with respect to the Notes to violate this Article 11, but failure to give such notice shall not affect the subordination of the Notes to the Senior Debt as provided in this Article 11. Section 11.07. Subrogation. After all Senior Debt is paid in full and until the Notes are paid in full, Holders of Notes shall be subrogated (equally and ratably with all other Indebtedness pari passu with the Notes) to the rights of holders of Senior Debt to receive distributions applicable to Senior Debt to the extent that distributions otherwise payable to the Holders of Notes have been applied to the payment of Senior Debt. A distribution made under this Article 11 to holders of Senior Debt that otherwise would have been made to Holders of Notes is not, as between the Company and Holders, a payment by the Company on the Notes. Section 11.08. Relative Rights. This Article 11 defines the relative rights of Holders of Notes and holders of Senior Debt. Nothing in this Indenture shall: (1) impair, as between the Company and Holders of Notes, the obligation of the Company, which is absolute and unconditional, to pay Accreted Value of, Liquidated Damages and premium, if any, on the Notes in accordance with their terms; 95

(2) affect the relative rights of Holders of Notes and creditors of the Company other than their rights in relation to holders of Senior Debt; or (3) prevent the Trustee or any Holder of Notes from exercising its available remedies upon a Default or Event of Default, subject to the rights of holders and owners of Senior Debt to receive distributions and payments otherwise payable to Holders of Notes. If the Company fails because of this Article 11 to pay Accreted Value of, Liquidated Damages or premium, if any, on a Note on the due date, the failure is still a Default or Event of Default. Section 11.09. Subordination May Not Be Impaired by Company No right of any holder of Senior Debt to enforce the subordination of the Indebtedness evidenced by the Notes may be impaired by any act or failure to act by the Company or any Holder or by the failure of the Company or any Holder to comply with this Indenture. Section 11.10. Distribution or Notice to Representative Whenever a distribution is to be made or a notice given to holders of Senior Debt, the distribution may be made and the notice given to their Representative. Upon any payment or distribution of assets of the Company referred to in this Article 11, the Trustee and the Holders of Notes shall be entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of such Representative or of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders of Notes for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior Debt and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 11. Section 11.11. Rights of Trustee and Paying Agent Notwithstanding the provisions of this Article 11 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment or distribution by the Trustee, and the Trustee and the Paying Agent may continue to make payments on the Notes, unless the Trustee has received at its Corporate Trust Office at least five Business Days prior to the date of such payment written notice of facts that would cause the payment of any Obligations with respect to the Notes to violate this Article 11. Only the Company or a Representative may give the notice. Nothing in this Article 11 shall impair the claims of, or payments to, the Trustee under or pursuant to Section 7.07 hereof. The Trustee in its individual or any other capacity may hold Senior Debt with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. 96

Section 11.12. Authorization to Effect Subordination. Each Holder of Notes, by the Holder's acceptance thereof, authorizes and directs the Trustee on such Holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination as provided in this Article 11, and appoints the Trustee to act as such Holder's attorney-in-fact for any and all such purposes. If the Trustee does not file a proper proof of claim or proof of debt in the form required in any proceeding referred to in Section 6.09 hereof at least 30 days before the expiration of the time to file such claim, the Representatives are hereby authorized to file an appropriate claim for and on behalf of the Holders of the Notes. Section 11.13. Amendments. The provisions of this Article 11 may not be amended or modified without the written consent of the holders of all Senior Debt. In addition, any amendment to, or waiver of, the provisions of this Article 11 that adversely affects the rights of the Holders of the Notes shall require the consent of the Holders of at least 66?% in aggregate principal amount at maturity of Notes then outstanding. ARTICLE 12 SATISFACTION AND DISCHARGE Section 12.01. Satisfaction and Discharge This Indenture shall be discharged and shall cease to be of further effect as to all Notes issued hereunder, when: (1) either (a) all Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or shall become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as shall be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire 97

indebtedness on the Notes not delivered to the Trustee for cancellation for Accreted Value, premium and Liquidated Damages, if any; (2) no Default or Event of Default has occurred and is continuing on the date of the deposit or shall occur as a result of the deposit and the deposit shall not result in a breach or violation of, or constitute a default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this Indenture; and (4) the Company has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be. In addition, the Company must deliver an Officers' Certificate to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. Notwithstanding the satisfaction and discharge of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the provisions of Section 12.02 and Section 8.06 shall survive. In addition, nothing in this Section 12.01 shall be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. Section 12.02. Notices Subject to the provisions of Section 8.06, all money deposited with the Trustee pursuant to Section 12.01 shall be held in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the Accreted Value, Liquidated Damages and premium, if any, for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the extent required by law. If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with Section 12.01 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company's and any Guarantor's obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 12.01; provided that if the Company has made any payment of Accreted Value, Liquidated Damages or premium, if any, on any Notes because of the reinstatement of its obligations, the 98

Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. ARTICLE 13 MISCELLANEOUS Section 13.01. Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with the duties imposed by TIA Section 318(c), the imposed duties shall control. Section 13.02. Notices.

THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE AND THE NOTES WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

Dated: ____________________ AMERICAN TOWER ESCROW CORPORATION By: ---------------------------- Name: Title: By: ---------------------------- Name: Title: This is one of the Notes referred to in the within-mentioned Indenture: THE BANK OF NEW YORK, as Trustee By: ---------------------------- Authorized Signatory A-3

[BACK OF NOTE] 12.25% Senior Subordinated Discount Notes Due 2008 Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 1. Interest. American Tower Escrow Corporation (together with its successors, the "Company"), shall pay no interest on the principal amount of this Note. The Accreted Value of this Note will increase between the Issue Date and maturity at a rate of 12.25% per annum calculated on a semi-annual bond equivalent basis using a 360-day year comprised of twelve 30-day months, such that the Accreted Value at maturity of this Note will equal the full principal amount at maturity of this Note. [If Original Notes then insert: If (i) on or prior to the 90th day following the Issue Date (or such longer period as required by applicable law), neither a registration statement (the "Exchange Registration Statement") under the Securities Act, registering a note substantially identical to this Note (except that such Note will not contain terms with respect to the Additional Interest payments described below or transfer restrictions) pursuant to an exchange offer (the "Exchange Offer") nor a registration statement registering this Note for resale (a "Shelf Registration Statement") has been filed with the Securities and Exchange Commission, (ii) on or prior to the 180th day following the Issue Date, neither the Exchange Registration Statement nor the Shelf Registration Statement has become or been declared effective, (iii) on or prior to 30 business days following the Effectiveness Target Date, the Exchange Offer has not been consummated, or (iv) either the Exchange Registration Statement or, if applicable, the Shelf Registration Statement is declared effective but (A) thereafter ceases to be effective or (B) ceases to be usable in connection with certain resales, in each case (i) through (iv) upon the terms and conditions set forth in the Registration Rights Agreement (each such event referred to in clauses (i) through (iv), a "Registration Default"), then liquidated damages will be assessed with respect to this Note at an amount of $0.05 per week per $1,000 of Accreted Value of this Note (the "Liquidated Damages") for the 90-day period immediately following the occurrence of the Registration Default, which amount shall be increased by $0.05 per week per $1,000 of Accreted Value of this Note at the beginning of each subsequent 90-day period (provided that such amount shall not exceed $0.50 per week per $1,000 of Accreted Value of this Note in the aggregate) and such amount shall be payable until such time (the "Step-Down Date") as no Registration Default is in effect (after which such amount will be restored to its initial amount). In no event shall the Company be required to pay Liquidated Damages for more than one Registration Default at any given time. Liquidated Damages shall be paid semi-annually on February 1 and August 1 in each year; and the amount of Liquidated Damages shall be determined on the basis of the number of days actually elapsed. Any unpaid Liquidated Damages on this Note upon the issuance of an Exchange Note (as defined in the Indenture) in exchange for this Note shall cease to be payable to the Holder hereof but such Liquidated Damages shall be payable on the next February 1 or August 1 to the Holder thereof.] The Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue Accreted Value and premium [If Original Notes then insert: or Liquidated Damages], if any, at a rate that is 1% per annum in excess of the then applicable rate of accretion of the Notes, to the extent lawful. A-4

2. Method of Payment. The Notes shall be payable as to Accreted Value, premium or Liquidated Damages, if any, at the office or agency of the Paying Agent and Registrar maintained for such purpose within the City and State of New York, or, at the option of the Company, payment may be made by check mailed to the Holders at their addresses set forth in the register of Holders, provided that payment by wire transfer of immediately available funds will be required with respect to Accreted Value of and premium, if any, on, all Global Notes and all other Notes the Holders of which have provided wire transfer instructions to the Company or the Paying Agent. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 3. Paying Agent and Registrar. Initially, The Bank of New York, the Trustee under the Indenture, shall act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 4. Indenture. The Company issued the Notes under an Indenture dated as of January 29, 2003 (the "Indenture") among the Company, the Guarantors (from and after the consummation of the Escrow Corp. Merger) and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code Sections 77aaa-77bbbb) (the "Trust Indenture Act"). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are obligations of the Company. The Original Notes are limited to $808 million in aggregate principal at maturity amount.

Merger has not occurred on or before the 60th day after the Issue Date or, at the request of the Company prior to such date if the Company in good faith reasonably determines that the conditions to the Escrow Corp.

(a) If a Change of Control occurs, the Company shall make an offer (a "Change of Control Offer") to each Holder to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at a purchase price, in cash, equal to 101% of the Accreted Value of the Notes on the date of purchase plus Liquidated Damages, if any, on the Notes purchased, to the date of purchase (a "Change of Control Payment"). Within 15 days following any Change of Control, the Company shall mail a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. (b) When the aggregate amount of Excess Proceeds exceeds $10.0 million, the Company shall commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an "Asset Sale Offer") pursuant to Section 3.09 of the Indenture to purchase the maximum principal amount at maturity of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the Accreted Value thereof, plus Liquidated Damages, if any, to the date of purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the remaining Excess Proceeds may be used for any purpose not otherwise prohibited by the Indenture. If the aggregate Accreted Value of Notes surrendered by Holders thereof, and the amounts due to any holders of any other debt of the Company entitled to receive a comparable asset sales offer, exceeds the amount of Excess Proceeds, the Trustee shall select the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase shall receive an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled "Option of Holder to Elect Purchase" on the reverse of the Notes.

Upon receipt of a request for such an exchange or transfer, the Warrant Agent shall cancel the applicable Unrestricted Definitive Warrant and increase or cause to be increased the amount of one of the Unrestricted Global Warrants. 13

If any such exchange or transfer from a Definitive Warrant to a beneficial interest is effected pursuant to subparagraphs (ii)(B) or (iii) above at a time when an Unrestricted Global Warrant has not yet been issued, the Company shall issue and, upon receipt of an Warrant Countersignature Order in accordance with Section 3.2 hereof, the Warrant Agent shall countersign one or more Unrestricted Global Warrants in the number equal to the number of beneficial interests of Definitive Warrants so transferred. (e) Transfer and Exchange of Definitive Warrants for Definitive Warrants. Upon request by a Holder of Definitive Warrants and such Holder's compliance with the provisions of this Section 3.5(e), the Warrant Registrar shall register the transfer or exchange of Definitive Warrants. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Warrant Registrar the Definitive Warrants duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Warrant Registrar duly executed by such Holder or by its attorney, duly authorized in writing. In addition, the requesting Holder shall provide any additional certifications, documents and information, as applicable, required pursuant to the following provisions of this Section 3.5(e). (i) Restricted Definitive Warrants to Restricted Definitive Warrants. Any Restricted Definitive Warrant may be transferred to and registered in the name of Persons who take delivery thereof in the form of a Restricted Definitive Warrant if the Warrant Registrar receives the following: (A) if the transfer will be made pursuant to Rule 144A under the Securities Act, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; (B) if the transfer will be made pursuant to Rule 903 or Rule 904, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof; or (C) if the transfer will be made pursuant to any other exemption from the registration requirements of the Securities Act, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications, certificates and Opinion of Counsel required by item (3) thereof, if applicable. (ii) Restricted Definitive Warrants to Unrestricted Definitive Warrants. Any Restricted Definitive Warrant may be exchanged by the Holder thereof for an Unrestricted Definitive Warrant or transferred to a Person or Persons who take delivery thereof in the form of an Unrestricted Definitive Warrant if: (A) any such transfer is effected pursuant to the Registration Statement in accordance with the Warrant Registration Rights Agreement; or (B) the Warrant Registrar receives the following: (1) if the Holder of such Restricted Definitive Warrants proposes to exchange such Warrants for an Unrestricted Definitive Warrant, a certificate from such Holder in the form of Exhibit C hereto, including the certifications in item (1)(d) thereof; or 14

(iii) Unrestricted Definitive Warrants to Unrestricted Definitive Warrants. A Holder of Unrestricted Definitive Warrants may transfer such Warrants to a Person who takes delivery thereof in the form of an Unrestricted Definitive Warrant. Upon receipt of a request to register such a transfer, the Warrant Registrar shall register the Unrestricted Definitive Warrants pursuant to the instructions from the Holder thereof. (f) Registration Statement. Upon the effectiveness of the Registration Statement and sales of Warrants in connection therewith in accordance with the Warrant Registration Rights Agreement, the Company shall issue and, upon receipt of a Warrant Countersignature Order in accordance with Section 3.2, the Warrant Agent shall countersign (i) one or more Unrestricted Global Warrants in an amount equal to the amount of the beneficial interests in the Restricted Global Warrants sold under such Registration Statement and (ii) Unrestricted Definitive Warrants in an amount equal to the amount of the beneficial interests of the Restricted Definitive Warrants sold under such Registration Statement. Concurrently with the issuance of such Warrants, the Warrant Agent shall cause the amount of the applicable Restricted Global Warrants to be reduced accordingly, and the Company shall execute and the Warrant Agent shall countersign and deliver to the Persons designated by the Holders of Definitive Warrants so accepted Unrestricted Definitive Warrants in the appropriate amount. (g) Legends. The following legends shall appear on the face of all Global Warrants and Definitive Warrants issued under this Warrant Agreement unless specifically stated otherwise in the applicable provisions of this Warrant Agreement.

THE WARRANT AGREEMENT CONTAINS A PROVISION REQUIRING THE WARRANT AGENT TO REFUSE TO REGISTER ANY TRANSFER OF THIS SECURITY IN VIOLATION OF THE FOREGOING." (B) Notwithstanding the foregoing, any Global Warrant or Definitive Warrant issued pursuant to subparagraphs (b)(iv), (c)(ii), (c)(iii), (d)(ii), (d)(iii), (e)(ii), (e)(iii) or (f) to this Section 3.5 (and all Warrants issued in exchange therefor or substitution thereof) shall not bear the Private Placement Legend.

(iv) Regulation S Legend. Each Warrant that is a Registrable Security and issued pursuant to Regulation S shall bear the following legend in substantially the following form unless otherwise agreed by the Company and the holder thereof: "THIS WARRANT AND THE SECURITIES TO BE ISSUED UPON ITS EXERCISE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT AND THE WARRANT MAY NOT BE EXERCISED BY OR ON BEHALF OF ANY U.S. PERSON UNLESS REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE. IN ORDER TO EXERCISE THIS WARRANT, THE HOLDER MUST FURNISH TO THE COMPANY AND THE WARRANT AGENT EITHER (A) A WRITTEN CERTIFICATION THAT IT IS NOT A U.S. PERSON AND THE WARRANT IS NOT BEING EXERCISED ON BEHALF OF A U.S. PERSON OR (B) A WRITTEN OPINION OF COUNSEL TO THE EFFECT THAT THE SECURITIES DELIVERED UPON EXERCISE OF THE WARRANT HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OR THAT THE DELIVERY OF SUCH SECURITIES IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. TERMS IN THIS LEGEND HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT." (h) Cancellation and/or Adjustment of Global Warrants. 17

At such time as all beneficial interests in a particular Global Warrant have been exercised or exchanged for Definitive Warrants or a particular Global Warrant has been exercised, redeemed, repurchased or canceled in whole and not in part, each such Global Warrant shall be returned to or retained and canceled by the Warrant Agent in accordance with Section 3.8 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Warrant is exercised or exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Warrant or for Definitive Warrants, the amount of Warrants represented by such Global Warrant shall be reduced accordingly and an endorsement shall be made on such Global Warrant by the Warrant Agent or by the Depositary at the direction of the Warrant Agent to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Warrant, such other Global Warrant shall be increased accordingly and an endorsement shall be made on such Global Warrant by the Warrant Agent or by the Depositary at the direction of the Warrant Agent to reflect such increase. (i) General Provisions Relating to Transfers and Exchanges. (i) To permit registrations of transfers and exchanges, the Company shall execute and the Warrant Agent shall countersign Global Warrants and Definitive Warrants upon the Company's order or at the Warrant Registrar's request. (ii) No service charge shall be made to a holder of a beneficial interest in a Global Warrant or to a holder of a Definitive Warrant for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith. (iii) All Global Warrants and Definitive Warrants issued upon any registration of transfer or exchange of Global Warrants or Definitive Warrants shall be the duly authorized, executed and issued warrants for Common Stock of the Company, not subject to any preemptive rights, and entitled to the same benefits under this Warrant Agreement, as the Global Warrants or Definitive Warrants surrendered upon such registration of transfer or exchange. (iv) Prior to due presentment for the registration of a transfer of any Warrant, the Warrant Agent, and the Company may deem and treat the Person in whose name any Warrant is registered as the absolute owner of such Warrant for all purposes and none of the Warrant Agent, or the Company shall be affected by notice to the contrary. (v) The Warrant Agent shall countersign Global Warrants and Definitive Warrants in accordance with the provisions of Section 3.2 hereof. (j) Facsimile Submissions to Warrant Agent. All certifications, certificates and Opinions of Counsel required to be submitted to the Warrant Registrar pursuant to this Section 3.5 to effect a registration of transfer or exchange may be submitted by facsimile. Notwithstanding anything herein to the contrary, as to any certificates and/or certifications delivered to the Warrant Registrar pursuant to this Section 3.5, the Warrant Registrar's duties shall be limited to confirming that any such certifications and certificates delivered to it are in the form of Exhibits B and C attached hereto. The Warrant Registrar shall not be responsible for confirming the truth or accuracy of representations made in any such certifications or certificates. As to any Opinions 18

of Counsel delivered pursuant to this Section 3.5, the Warrant Registrar may rely upon, and be fully protected in relying upon, such opinions. 3.6. REPLACEMENT WARRANTS. If any mutilated Warrant is surrendered to the Warrant Agent or the Company and the Warrant Agent receives evidence to its satisfaction of the destruction, loss or theft of any Warrant, the Company shall issue and the Warrant Agent, upon receipt of a Warrant Countersignature Order, shall countersign a replacement Warrant if the Warrant Agent's requirements are met. If required by the Warrant Agent or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Warrant Agent and the Company to protect the Company, the Warrant Agent, any Agent and any agent for purposes of the countersignature from any loss that any of them may suffer if a Warrant is replaced. The Company may charge for its expenses in replacing a Warrant. Every replacement Warrant is an additional warrant of the Company and shall be entitled to all of the benefits of this Warrant Agreement equally and proportionately with all other Warrants duly issued hereunder. 3.7. TEMPORARY WARRANTS. Until certificates representing Warrants are ready for delivery, the Company may prepare and the Warrant Agent, upon receipt of a Warrant Countersignature Order, shall issue temporary Warrants. Temporary Warrants shall be substantially in the form of certificated Warrants but may have variations that the Company considers appropriate for temporary Warrants and as shall be reasonably acceptable to the Warrant Agent. Without unreasonable delay, the Company shall prepare and the Warrant Agent, as soon as practicable upon receipt of the written order of the Company signed by an officer of the Company, shall countersign definitive Warrants in exchange for temporary Warrants. Holders of temporary Warrants shall be entitled to all of the benefits of this Warrant Agreement. 3.8. CANCELLATION. Subject to Section 3.5(h) hereof, the Company at any time may deliver Warrants to the Warrant Agent for cancellation. The Warrant Registrar and Warrant Paying Agent shall forward to the Warrant Agent any Warrants surrendered to them for registration of transfer, exchange or exercise. The Warrant Agent and no one else shall cancel all Warrants surrendered for registration of transfer, exchange, exercise, replacement or cancellation and shall dispose of such canceled Warrants in its customary manner. The Company may not issue new Warrants to replace Warrants that have been exercised or that have been delivered to the Warrant Agent for cancellation. SECTION 4. SEPARATION OF WARRANTS; TERMS OF WARRANTS; EXERCISE OF WARRANTS (a) The Notes and Warrants will not be separately transferable until the Separation Date. Subject to the terms of this Agreement, each Warrant holder shall have the right, which may be exercised during the period commencing at the opening of business on January 29, 2006 until August 1, 2008 (the "Exercise Period"), to receive from the Company the number of fully paid and nonassessable Warrant Shares which the holder may at the time be entitled to receive on exercise of such Warrants and payment of the Exercise Price (i) by tendering Notes having an Accreted Value to the date of exercise 19

equal to the Exercise Price (ii) by tendering Warrants as set forth below, (iii) by tendering any combination of Notes and Warrants or (iv) in cash in United States dollars by wire transfer or by certified or official bank check payable to the order of the Company the Exercise Price then in effect for such Warrant Shares; provided that holders shall be able to exercise their Warrants only if a registration statement relating to the Warrant Shares is then in effect, or the exercise of such Warrants is exempt from the registration requirements of the Securities Act, and such securities are qualified for sale or exempt from qualification under the applicable securities laws of the states in which the various holders of the Warrants or other persons to whom it is proposed that the Warrant Shares be issued on exercise of the Warrants reside. Each holder may exercise its right during the Exercise Period, to receive Warrant Shares on a net basis, such that, without the exchange of any funds, the holder will receive such number of Warrant Shares equal to the product of (A) the number of Warrant Shares for which such Warrant is exercisable as of the date of exercise (if the Exercise Price were being paid in cash) and (B) the Cashless Exercise Ratio. The Cashless Exercise Ratio shall equal a fraction the numerator of which is the Market Value per share of Common Stock minus the Exercise Price per share as of the date of exercise and the denominator of which is the Market Value per share on the date of exercise. Each Warrant not exercised on or prior to August 1, 2008 (the "Expiration Date") shall become void and all rights thereunder and all rights in respect thereof under this agreement shall cease as of such time. No adjustments as to dividends will be made upon exercise of the Warrants. Notwithstanding the foregoing, if the Escrow Corp. Merger has not been consummated and the Notes have been mandatorily redeemed pursuant to Section 3.08 of the Indenture (the "Redemption Date"), each Warrant shall become void and all rights thereunder and all rights in respect thereof under this Agreement shall cease as of the Redemption Date. (b) In order to exercise all or any of the Warrants represented by a Warrant Certificate, the holder thereof must deliver to the Warrant Agent at its corporate trust office set forth in Section 15 hereof the Warrant Certificate and the form of election to purchase on the reverse thereof duly filled in and signed, which signature shall be medallion guaranteed by an institution which is a member of a Securities Transfer Association recognized signature guarantee program, and upon payment to the Warrant Agent for the account of the Company of the Exercise Price, which is set forth in the form of Warrant Certificate attached hereto as Exhibit A, as adjusted as herein provided, for the number of Warrant Shares in respect of which such Warrants are then exercised. Payment of the aggregate Exercise Price shall be made in the manner provided in Section 4(a) hereof. (c) Subject to the provisions of Section 5 hereof, upon compliance with clause (b) above, the Warrant Agent shall deliver or cause to be delivered with all reasonable dispatch, to or upon the written order of the holder and in such name or names as the Warrant holder may designate, a certificate or certificates for the number of whole Warrant Shares issuable upon the exercise of such Warrants or other securities or property to which such holder is entitled hereunder, together with cash as provided in Section 9 hereof; provided that if any consolidation, merger or lease or sale of assets is proposed to be effected by the Company as described in Section 8(k) hereof, or a tender offer or an exchange offer for shares of Common Stock shall be made, upon such surrender of Warrants and payment of the Exercise Price as aforesaid, the Warrant Agent shall, as soon as reasonably possible, deliver or cause to be delivered the full number of Warrant Shares issuable upon the exercise of such Warrants in the manner described in this sentence or other securities or property to which such holder is entitled hereunder, together with cash as provided in Section 9 hereof. Such certificate or certificates shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares as of the date of the surrender of such Warrants and payment of the Exercise Price. (d) The Warrants shall be exercisable, at the election of the holders thereof, either in full or from time to time in part pursuant to the terms of this Section 4. If less than all the Warrants 20

represented by a Warrant Certificate are exercised, such Warrant Certificate shall be surrendered and a new Warrant Certificate of the same tenor and for the number of Warrants which were not exercised shall be executed by the Company and delivered to the Warrant Agent and the Warrant Agent shall countersign the new Warrant Certificate, registered in such name or names as may be directed in writing by the holder, and shall deliver the new Warrant Certificate to the Person or Persons entitled to receive the same. (e) All Warrant Certificates surrendered upon exercise of Warrants shall be cancelled by the Warrant Agent. Such cancelled Warrant Certificates shall then be disposed of by the Warrant Agent in its customary manner. The Warrant Agent shall account promptly to the Company with respect to Warrants exercised and concurrently pay to the Company all monies received by the Warrant Agent for the purchase of the Warrant Shares through the exercise of such Warrants. (f) The Warrant Agent shall keep copies of this Agreement and any notices given or received hereunder available for inspection by the holders upon reasonable prior written notice during normal business hours at its office. The Company shall supply the Warrant Agent from time to time with such numbers of copies of this Agreement as the Warrant Agent may request. (g) The Company has agreed pursuant to the Warrant Registration Rights Agreement to file within 90 days after the issuance of the Warrants and use its reasonable best efforts to make effective, subject to certain exceptions detailed in the Warrant Registration Rights Agreement, on or before 180 days after such date a shelf registration statement covering the resale of the Warrants, the issuance by the Company's common stock upon the exercise of the warrants resold pursuant to such registration statement and the resale of the Warrant Shares by the holder thereof on the appropriate form under the Securities Act, and to use its reasonable best efforts (subject to certain "black-out" periods not to exceed 60 days in any calendar year subject to extension for 30 days in certain circumstances) to keep such registration statement continuously effective under the Securities Act, subject to certain exceptions, until two years following the Closing Date. (h) The holders of the warrants will have no right to vote on matters submitted to the stockholders of the Company and will have no right to receive dividends. The holders of the warrants will not be entitled to share in the assets of the Company in the event of liquidation, dissolution or the winding up of the Company. In the event a bankruptcy or reorganization is commenced by or against the Company, a bankruptcy court may hold that unexercised warrants are executory contracts which may be subject to rejection by the Company with approval of the bankruptcy court, and the holders of the warrants may, even if sufficient funds are available, receive nothing or a lesser amount as a result of any such bankruptcy case than they would be entitled to if they had exercised their warrants prior to the commencement of any such case. SECTION 5. PAYMENT OF TAXES. The Company will pay all documentary stamp taxes attributable to the initial issuance of Warrant Shares upon the exercise of Warrants; provided that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issue of any Warrant Certificates or any certificates for Warrant Shares in a name other than that of the registered holder of a Warrant Certificate surrendered upon the exercise of a Warrant, and the Company shall not be required to issue or deliver such Warrant Certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Company the amount of such tax or shall have established to the satisfaction of the Company that such tax has been paid; provided further that the Company shall not be required to pay any tax or taxes which may be payable in the event of a taxable distribution to holders of the Company's common stock that results in an adjustment to the number of Warrant Shares or other 21

consideration for which a Warrant may be exercised, and results in the holders of the Warrants to be deemed to have received a distribution subject to United States federal income tax as a dividend. SECTION 6. RESERVATION OF WARRANT SHARES. (a) The Company will at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued Common Stock or its authorized and issued Common Stock held in its treasury, for the purpose of enabling it to satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the maximum number of shares of Common Stock which may then be deliverable upon the exercise of all outstanding Warrants. (b) The Company or, if appointed, the transfer agent for the Common Stock (the "Transfer Agent") and every subsequent transfer agent for any shares of the Company's capital stock issuable upon the exercise of any of the rights of purchase aforesaid will be irrevocably authorized and directed at all times to reserve such number of authorized shares as shall be required for such purpose. The Company will keep a copy of this Agreement on file with the Transfer Agent and with every subsequent transfer agent for any shares of the Company's capital stock issuable upon the exercise of the rights of purchase represented by the Warrants. The Warrant Agent is hereby irrevocably authorized to requisition from time to time from such Transfer Agent the stock certificates required to honor outstanding Warrants upon exercise thereof in accordance with the terms of this Agreement. The Company will supply such Transfer Agent with duly executed certificates for such purposes and will provide or otherwise make available any cash which may be payable as provided in Section 9 hereof. The Company will furnish such Transfer Agent a copy of all notices of adjustments, and certificates related thereto, transmitted to each holder pursuant to Section 11 hereof. (c) The Company covenants that all Warrant Shares which may be issued upon exercise of Warrants will, upon issue, be fully paid, nonassessable, free of preemptive rights and free from all taxes, liens, charges and security interests with respect to the issuance thereof. SECTION 7. OBTAINING STOCK EXCHANGE LISTINGS. The Company will from time to time take all action which may be necessary so that the Warrant Shares, immediately upon their issuance upon the exercise of Warrants, will be listed on the principal securities exchanges, automated quotation systems or other markets within the United States of America, if any, on which other shares of Common Stock are then listed, if any. SECTION 8. ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF WARRANT SHARES ISSUABLE. The Exercise Price and the number of Warrant Shares issuable upon the exercise of each Warrant are subject to adjustment from time to time upon the occurrence of the events enumerated in this Section 8. For purposes of this Section 8, "Common Stock" means shares now or hereafter authorized of any class of common stock of the Company and any other stock of the Company, however designated, that has the right (subject to any prior rights of any class or series of preferred stock) to participate in any distribution of the assets or earnings of the Company without limit as to per share amount. (a) Adjustment for Change in Capital Stock. 22

If the Company (i) pays a dividend or makes a distribution on its Common Stock in shares of its Common Stock, (ii) subdivides its outstanding shares of Common Stock into a greater number of shares, (iii) combines its outstanding shares of Common Stock into a smaller number of shares, (iv) makes a distribution on its Common Stock in shares of its capital stock other than Common Stock or (v) issues by reclassification of its Common Stock any shares of its capital stock, then the Exercise Price in effect immediately prior to such action shall be proportionately adjusted so that the holder of any Warrant thereafter exercised may receive the aggregate number and kind of shares of capital stock of the Company which he would have owned immediately following such action if such Warrant had been exercised immediately prior to such action. The adjustment shall become effective immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification. If, after an adjustment, a holder of a Warrant upon exercise of it may receive shares of two or more classes of capital stock of the Company, the Company shall determine, in good faith, the allocation of the adjusted Exercise Price between the classes of capital stock. After such allocation, the exercise privilege and the Exercise Price of each class of capital stock shall thereafter be subject to adjustment on terms comparable to those applicable to Common Stock in this Section 8. Such adjustment shall be made successively whenever any event listed above shall occur. (b) Adjustment for Rights Issue. If the Company distributes any rights, options or warrants to all holders of its Common Stock entitling them for a period expiring within 45 days after the record date mentioned below to purchase shares of Common Stock at a price per share less than the Fair Value per share on that record date, the Exercise Price shall be adjusted in accordance with the formula: O + N X P ----- E' = E X M --------------- O + N where: E' = the adjusted Exercise Price. E = the current Exercise Price. O = the number of shares of Common Stock outstanding on the record date. N = the number of additional shares of Common Stock issued pursuant to such rights, options or warrants. P = the aggregate price per share of the additional shares. M = the Fair Value per share of Common Stock on the record date. The adjustment shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the record date for the determination of stockholders entitled to receive the rights, options or warrants. If at the end of the period during which such rights, options or warrants are exercisable, not all rights, options or warrants shall have been 23

exercised, the Exercise Price shall be immediately readjusted to what it would have been if "N" in the above formula had been the number of shares actually issued. (c) Adjustment for Other Distributions. If the Company distributes to all holders of its Common Stock any of its assets or debt securities or any rights or warrants to purchase debt securities of the Company, the Exercise Price shall be adjusted in accordance with the formula: M - F E' = E X --------- M where: E' = the adjusted Exercise Price. E = the current Exercise Price. M = the Fair Value per share of Common Stock on the record date mentioned below. F = the fair market value on the record date of the assets, securities, rights or warrants to be distributed in respect of one share of Common Stock as determined in good faith by the Board of Directors of the Company (the "Board of Directors"). The adjustment shall be made successively whenever any such distribution is made and shall become effective immediately after the record date for the determination of stockholders entitled to receive the distribution. This Section 8(c) does not apply to cash dividends or cash distributions paid out of consolidated current or retained earnings as shown on the books of the Company prepared in accordance with generally accepted accounting principles. Also, this Section 8(c) does not apply to rights, options or warrants referred to in Section 8(b) hereof. (d) Adjustment for Common Stock Issue. If the Company issues shares of Common Stock for a consideration per share less than the Fair Value per share on the date the Company fixes the offering price of such additional shares, the Exercise Price shall be adjusted in accordance with the formula: P --- E' = E X O + M ----------- A where: E' = the adjusted Exercise Price. 24

E = the then current Exercise Price. O = the number of shares outstanding immediately prior to the issuance of such additional shares. P = the aggregate consideration received for the issuance of such additional shares. M = the Fair Value per share on the date of issuance of such additional shares. A = the number of shares outstanding immediately after the issuance of such additional shares. The adjustment shall be made successively whenever any such issuance is made, and shall become effective immediately after such issuance. This subsection (d) does not apply to: (1) any of the transactions described in subsections (a), (b), (c) and (e) of this Section 8, (2) the exercise of Warrants, or the conversion or exchange of other securities convertible or exchangeable for Common Stock the issuance of which caused an adjustment to be made under Section 8(e), (3) Common Stock issued to the Company's employees (or employees of its subsidiaries) under bona fide employee benefit plans adopted by the Board of Directors and approved by the holders of Common Stock when required by law, if such Common Stock would otherwise be covered by this subsection (d) (but only to the extent that the aggregate number of shares excluded hereby and issued after the date of this Warrant Agreement shall not exceed 10% of the Common Stock outstanding at the time of the adoption of each such plan, exclusive of anti-dilution adjustments thereunder), (4) Common Stock issued to shareholders of any person which merges into the Company, or with a subsidiary of the Company, in proportion to their stock holdings of such person immediately prior to such merger, upon such merger, provided that if such person is an Affiliate of the Company, the Board of Directors shall have obtained a fairness opinion from a nationally recognized investment banking, appraisal or valuation firm, which is not an Affiliate of the Company, stating that the consideration received in such merger is fair to the Company from a financial point of view, or (5) the issuance of shares of Common Stock pursuant to rights, options, warrants or convertible securities which were originally issued in a Non-Affiliate Sale (as defined below) together with one or more other securities as part of a unit at a price per unit. (e) Adjustment for Convertible Securities Issue. If the Company issues any securities convertible into or exchangeable for Common Stock (other than securities issued in transactions described in subsections (b) and (c) of this Section 8) for a consideration per share of Common Stock initially deliverable upon conversion or exchange of such 25

securities less than the Fair Value per share on the date of issuance of such securities, the Exercise Price shall be adjusted in accordance with this formula: P --- O + M E' = E X ---------- O + D where: E' = the adjusted Exercise Price. E = the then current Exercise Price. O = the number of shares outstanding immediately prior to the issuance of such securities. P = the aggregate consideration received for the issuance of such securities. M = the Fair Value per share on the date of issuance of such securities. D = the maximum number of shares deliverable upon conversion or in exchange for such securities at the initial conversion or exchange rate. The adjustment shall be made successively whenever any such issuance is made, and shall become effective immediately after such issuance. If all of the Common Stock deliverable upon conversion or exchange of such securities have not been issued when such securities are no longer outstanding, then the Exercise Price shall promptly be readjusted to the Exercise Price which would then be in effect had the adjustment upon the issuance of such securities been made on the basis of the actual number of shares of Common Stock issued upon conversion or exchange of such securities. This subsection (e) does not apply to convertible securities issued to shareholders of any person which merges into the Company, or with a subsidiary of the Company, in proportion to their stock holdings of such person immediately prior to such merger, upon such merger, provided that if such person is an Affiliate of the Company, the Board of Directors shall have obtained a fairness opinion from a nationally recognized investment banking, appraisal or valuation firm, which is not an Affiliate of the Company, stating that the consideration received in such merger is fair to the Company from a financial point of view. (f) Consideration Received. For purposes of any computation respecting consideration received pursuant to subsections (d), and (e) of this Section 8, the following shall apply: (1) in the case of the issuance of shares of Common Stock for cash, the consideration shall be the amount of such cash, provided that in no case shall any deduction be made for any commissions, discounts or other expenses incurred by the Company for any underwriting of the issue or otherwise in connection therewith; 26

(2) in the case of the issuance of shares of Common Stock for a consideration in whole or in part other than cash, the consideration other than cash shall be deemed to be the fair market value thereof as determined in good faith by the Board of Directors (irrespective of the accounting treatment thereof), whose determination shall be conclusive, and described in a Board resolution which shall be filed with the Warrant Agent; (3) in the case of the issuance of securities convertible into or exchangeable for shares, the aggregate consideration received therefor shall be deemed to be the consideration received by the Company for the issuance of such securities plus the additional minimum consideration, if any, to be received by the Company upon the conversion or exchange thereof (the consideration in each case to be determined in the same manner as provided in clauses (1) and (2) of this subsection); and (4) in the case of the issuance of shares of Common Stock pursuant to rights, options or warrants which rights, options or warrants were originally issued together with one or more other securities as part of a unit at a price per unit, the consideration shall be deemed to be the fair value of such rights, options or warrants at the time of issuance thereof as determined in good faith by the Board of Directors whose determination shall be conclusive and described in a Board resolution which shall be filed with the Warrant Agent plus the additional minimum consideration, if any, to be received by the Company upon the exercise, conversion or exchange thereof (as determined in the same manner as provided in clauses (1) and (2) of this subsection). (g) When De Minimis Adjustment May Be Deferred. No adjustment in the Exercise Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Exercise Price; provided however, that any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 8 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be, it being understood that no such rounding shall be made under subsection (o). (h) When No Adjustment Required. No adjustment need be made for a transaction referred to Section 8(a), (b), (c), (d), (e) or (f) hereof, if Warrant holders are to participate (without being required to exercise their Warrants) in the transaction on a basis and with notice that the Board of Directors determines to be fair and appropriate in light of the basis and notice on which holders of Common Stock participate in the transaction. No adjustment need be made for (i) rights to purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest (ii) a change in the par value or no par value of the Common Stock or (iii) the issuance by the Company of warrants to the Initial Purchasers on or about January 29, 2003. To the extent the Warrants become convertible into cash, no adjustment need be made thereafter as to the cash. Interest will not accrue on the cash. No adjustment shall be made pursuant to this Section 8 if such adjustment causes the Exercise Price to fall below the par value per Warrant Share. (i) Notice of Adjustment. Whenever the Exercise Price is adjusted, the Company shall provide the notices required by Section 10 hereof. (j) Notice of Certain Transactions. 27

If (i) the Company takes any action that would require an adjustment in the Exercise Price pursuant to Section 8(a), (b), (c), (d), (e) or (f) hereof and if the Company does not arrange for Warrant holders to participate pursuant to Section 8(h) hereof, (ii) the Company takes any action that would require a supplemental Warrant Agreement pursuant to Section 8(j) hereof or (iii) there is a liquidation or dissolution of the Company, then the Company shall mail to Warrant holders a notice stating the proposed record date for a dividend or distribution or the proposed effective date of a subdivision, combination, reclassification, consolidation, merger, transfer, lease, liquidation or dissolution. The Company shall mail the notice at least 15 days before such date. Failure to mail the notice or any defect in it shall not affect the validity of the transaction. (k) Reorganization of Company. Immediately after the date hereof, if the Company consolidates or merges with or into, or transfers or leases all or substantially all its assets to, any person, upon consummation of such transaction the Warrants shall automatically become exercisable if such transaction occurs within the Exercise Period for the kind and amount of securities, cash or other assets which the holder of a Warrant would have owned immediately after the consolidation, merger, transfer or lease if the holder had exercised the Warrant immediately before the effective date of the transaction. Concurrently with the consummation of such transaction, the corporation formed by or surviving any such consolidation or merger if other than the Company, or the person to which such sale or conveyance shall have been made, shall enter into (i) a supplemental Warrant Agreement so providing and further providing for adjustments which shall be as nearly equivalent as may be practical to the adjustments provided for in this Section 8(k) and (ii) a supplement to the Warrant Registration Rights Agreement providing for the assumption of the Company's obligations thereunder. The successor Company shall mail to Warrant holders a notice describing the supplemental Warrant Agreement and Warrant Registration Rights Agreement. If the issuer of securities deliverable upon exercise of Warrants under the supplemental Warrant Agreement is an affiliate of the formed, surviving, transferee or lessee corporation, that issuer shall join in the supplemental Warrant Agreement and Warrant Registration Rights Agreement. If this Section 8(k) applies, Sections 8(a), (b), (c), (d), (e) and (f) hereof do not apply. (l) Company Determination Final. Any determination that the Company or the Board of Directors must make pursuant to Section 8(a), (c), (d), (e), (f), (g), (h) or (i) hereof is conclusive. (m) Warrant Agent's Disclaimer. The Warrant Agent has no duty to determine when an adjustment under this Section 8 should be made, how it should be made or what it should be. The Warrant Agent has no duty to determine whether any provisions of a supplemental Warrant Agreement under Section 8(k) hereof are correct. The Warrant Agent makes no representation as to the validity or value of any securities or assets issued upon exercise of Warrants. The Warrant Agent shall not be responsible for the Company's failure to comply with this Section 8. (n) When Issuance or Payment May Be Deferred. In any case in which this Section 8 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event (i) issuing to the holder of any Warrant exercised after such record date the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise over and 28

above the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise on the basis of the Exercise Price and (ii) paying to such holder any amount in cash in lieu of a fractional share pursuant to Section 10 hereof; provided that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional Warrant Shares, other capital stock and cash upon the occurrence of the event requiring such adjustment. (o) Adjustment in Number of Shares. Upon each adjustment of the Exercise Price pursuant to this Section 8, each Warrant outstanding prior to the making of the adjustment in the Exercise Price shall thereafter evidence the right to receive upon payment of the adjusted Exercise Price that number of shares of Common Stock (calculated to the nearest hundredth) obtained from the following formula: N' = N X E --- E' where: N' = the adjusted number of Warrant Shares issuable upon exercise of a Warrant by payment of the adjusted Exercise Price. N = the number or Warrant Shares previously issuable upon exercise of a Warrant by payment of the Exercise Price prior to adjustment. E' = the adjusted Exercise Price. E = the Exercise Price prior to adjustment. (p) Form of Warrants. Irrespective of any adjustments in the Exercise Price or the number or kind of shares purchasable upon the exercise of the Warrants, Warrants theretofore or thereafter issued may continue to express the same price and number and kind of shares as are stated in the Warrants initially issuable pursuant to this Agreement. SECTION 9. FRACTIONAL INTERESTS. The Company shall not be required to issue fractional Warrant Shares on the exercise of Warrants. If more than one Warrant shall be presented for exercise in full at the same time by the same holder, the number of full Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares purchasable on exercise of the Warrants so presented. If any fraction of a Warrant Share would, except for the provisions of this Section 9, be issuable on the exercise of any Warrants (or specified portion thereof), the Company shall pay an amount in cash equal to the Fair Value per Warrant Share, as determined on the day immediately preceding the date the Warrant is presented for exercise, multiplied by such fraction, computed to the nearest whole U.S. cent. 29

SECTION 10. NOTICES TO WARRANT HOLDERS. (a) Upon any adjustment of the Exercise Price pursuant to Section 8 hereof, the Company shall promptly thereafter (i) cause to be filed with the Warrant Agent a certificate of a firm of independent public accountants of recognized standing selected by the Board of Directors of the Company (who may be the regular auditors of the Company) setting forth the Exercise Price after such adjustment and setting forth in reasonable detail the method of calculation and the facts upon which such calculations are based and setting forth the number of Warrant Shares (or portion thereof) issuable after such adjustment in the Exercise Price, upon exercise of a Warrant and payment of the adjusted Exercise Price, which certificate shall be conclusive evidence of the correctness of the matters set forth therein, and (ii) cause to be given to each of the registered holders of Warrants at the address appearing on the Warrant register for each such registered holder written notice of such adjustments by first-class mail, postage prepaid. Where appropriate, such notice may be given in advance and included as a part of the notice required to be mailed under the other provisions of this Section 10. (b) In case: (i) the Company shall authorize the issuance to all holders of shares of Common Stock of rights, options or warrants to subscribe for or purchase shares of Common Stock or of any other subscription rights or warrants; (ii) the Company shall authorize the distribution to all holders of shares of Common Stock of evidences of its indebtedness or assets (other than dividends or cash distributions paid out of consolidated current or retained earnings as shown on the books of the Company prepared in accordance with generally accepted accounting principles or dividends payable in shares of Common Stock or distributions referred to in Section 10(a) hereof); (iii) of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the conveyance or transfer of the properties and assets of the Company substantially as an entirety, or of any reclassification or change of Common Stock issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or a tender offer or exchange offer for shares of Common Stock; (iv) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; or (v) the Company proposes to take any action (other than actions of the character described in Section 8(a) hereof) which would require an adjustment of the Exercise Price pursuant to Section 8 hereof; then the Company shall cause to be filed with the Warrant Agent and shall cause to be given to each of the registered holders of Warrants at his address appearing on the Warrant register, at least 20 days (or 10 days in any case specified in clauses (i) or (ii) above) prior to the applicable record date hereinafter specified, or promptly in the case of events for which there is no record date, by first-class mail, postage prepaid, a written notice stating (x) the date as of which the holders of record of shares of Common Stock to be entitled to receive any such rights, options, warrants or distribution are to be determined, (y) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock, or (z) the date on which any such consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock shall be entitled to exchange such shares for securities or other property, if any, deliverable upon such reclassification, consolidation, merger, conveyance, transfer, 30

dissolution, liquidation or winding up. The failure to give the notice required by this Section 11 or any defect therein shall not affect the legality or validity of any distribution, right, option, warrant, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding up, or the vote upon any action. (c) Nothing contained in this Agreement or in any of the Warrant Certificates shall be construed as conferring upon the holders of Warrants the right to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter, or any rights whatsoever as stockholders of the Company. SECTION 11. MERGER, CONSOLIDATION OR CHANGE OF NAME OF WARRANT AGENT. (g) Any corporation into which the Warrant Agent may be merged or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party, or any corporation succeeding to all or substantially all of the business of the Warrant Agent, shall be the successor to the Warrant Agent hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor warrant agent under the provisions of Section 13 hereof. In case at the time such successor to the Warrant Agent shall succeed to the agency created by this Agreement, and in case at that time any of the Warrant Certificates shall have been countersigned but not delivered, any such successor to the Warrant Agent may adopt the countersignature of the original Warrant Agent; and in case at that time any of the Warrant Certificates shall not have been countersigned, any successor to the Warrant Agent may countersign such Warrant Certificates either in the name of the predecessor Warrant Agent or in the name of the successor to the Warrant Agent; and in all such cases such Warrant Certificates shall have the full force and effect provided in the Warrant Certificates and in this Agreement. (h) In case at any time the name of the Warrant Agent shall be changed and at such time any of the Warrant Certificates shall have been countersigned but not delivered, the Warrant Agent whose name has been changed may adopt the countersignature under its prior name, and in case at that time any of the Warrant Certificates shall not have been countersigned, the Warrant Agent may countersign such Warrant Certificates either in its prior name or in its changed name, and in all such cases such Warrant Certificates shall have the full force and effect provided in the Warrant Certificates and in this Agreement. SECTION 12. WARRANT AGENT. The Warrant Agent undertakes only those duties and obligations specifically imposed on it by this Agreement upon the following terms and conditions, by all of which the Company and the holders of Warrants, by their acceptance thereof, shall be bound: (a) The statements contained herein and in the Warrant Certificates shall be taken as statements of the Company and the Warrant Agent assumes no responsibility for the correctness of any of the same except such as describe the Warrant Agent or action taken or to be taken by it. The Warrant Agent assumes no responsibility with respect to the distribution of the Warrant Certificates except as herein otherwise provided. 31

(b) The Warrant Agent shall not be responsible for any failure of the Company to comply with any of the covenants contained in this Agreement or in the Warrant Certificates to be complied with by the Company. (c) The Warrant Agent may consult at any time with counsel satisfactory to it (who may be counsel for the Company) and the Warrant Agent shall incur no liability or responsibility to the Company or to any holder of any Warrant Certificate in respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with the opinion or the advice of such counsel. (d) The Warrant Agent shall incur no liability or responsibility to the Company or to any holder of any Warrant Certificate for any action taken in reliance on any Warrant Certificate, certificate of shares, notice, resolution, waiver, consent, order, certificate, or other paper, document or instrument (whether in original or facsimile form) believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. The Warrant Agent need not investigate any fact or matter stated in such document. (e) The Company agrees to pay to the Warrant Agent reasonable compensation for all services rendered by the Warrant Agent in the execution of this Agreement, to reimburse the Warrant Agent for all expenses, taxes and governmental charges and other charges of any kind and nature incurred by the Warrant Agent in the execution of this Agreement. The Company shall indemnify the Warrant Agent and its agents, employees, officers, directors and shareholders for, and hold same harmless against, any and all losses, liabilities, claims, damages or expenses (including without limitation reasonable attorney's fees and expenses) incurred by it arising out of or in connection with the acceptance or administration of its duties under this Warrant Agreement, including the costs and expenses of enforcing this Warrant Agreement against the Company and defending itself against any claim (whether asserted by the Company or any Holder or any other person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense is determined by a court of competent jurisdiction to have been cause by its gross negligence or willful misconduct. The Warrant Agent shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Warrant Agent to so notify the Company shall not relieve the Company of its obligations hereunder. At the Warrant Agent's sole discretion, the Company shall defend the claim and the Warrant Agent shall cooperate in the defense at the Company's expense. The Warrant Agent may have separate counsel and the Company shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The benefits of this Section shall survive termination of this Agreement or change of Warrant Agent. (f) The Warrant Agent shall be under no obligation to institute any action, suit or legal proceeding or to take any other action likely to involve expense unless the Company or one or more registered holders of Warrants shall furnish the Warrant Agent with reasonable security and indemnity satisfactory to it for any costs and expenses which may be incurred, but this provision shall not affect the power of the Warrant Agent to take such action as it may consider proper, whether with or without any such security or indemnity. All rights of action under this Agreement or under any of the Warrants may be enforced by the Warrant Agent without the possession of any of the Warrant Certificates or the production thereof at any trial or other proceeding relative thereto, and any such action, suit or proceeding instituted by the Warrant Agent shall be brought in its name as Warrant Agent and any recovery of judgment shall be for the ratable benefit of the registered holders of the Warrants, as their respective rights or interests may appear. 32

(g) The Warrant Agent, and any stockholder, director, officer or employee of it, may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Agreement. Nothing herein shall preclude the Warrant Agent from acting in any other capacity for the Company or for any other legal entity. (h) The Warrant Agent shall act hereunder solely as agent for the Company, and its duties shall be determined solely by the provisions hereof. The Warrant Agent shall not be liable for anything which it may do or refrain from doing in connection with this Agreement except for its own gross negligence or willful misconduct. (i) The Warrant Agent shall not at any time be under any duty or responsibility to any holder of any Warrant Certificate to make or cause to be made any adjustment of the Exercise Price or number of the Warrant Shares or other securities or property deliverable as provided in this Agreement, or to determine whether any facts exist which may require any of such adjustments, or with respect to the nature or extent of any such adjustments, when made, or with respect to the method employed in making the same. The Warrant Agent shall not be accountable with respect to the validity or value or the kind or amount of any Warrant Shares or of any securities or property which may at any time be issued or delivered upon the exercise of any Warrant or with respect to whether any such Warrant Shares or other securities will when issued be validly issued and fully paid and nonassessable, and makes no representation with respect thereto. (i) The Warrant Agent shall not be required to, and shall not, expend or risk any of its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder. (j) In no event shall the Warrant Agent be liable for any consequential, punitive or special damages, or for the acts or omissions of its nominees, correspondents, designees, subagents or subcustodians. (k) The Warrant Agent shall not incur any liability for not performing any act or fulfilling any duty, obligation or responsibility hereunder by reason of any occurrence beyond the control of the Warrant Agent (including but not limited to any act or provision of any present or future law or regulation or governmental authority, any act of God or war, or the unavailability of the Federal Reserve Bank wire or telex or other wire or communication facility). (l) In the event of any ambiguity or uncertainty hereunder or in any notice, instruction or other communication received by the Warrant Agent hereunder, the Warrant Agent may, in its sole discretion, refrain from taking any action other than retain possession of the Warrant Shares, unless the Warrant Agent receives written instructions, signed by the Company, which eliminates such ambiguity or uncertainty. SECTION 13. CHANGE OF WARRANT AGENT. If the Warrant Agent shall become incapable of acting as Warrant Agent, the Company shall appoint a successor to such Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such incapacity by the Warrant Agent or 33

by the registered holder of a Warrant Certificate, then the registered holder of any Warrant or the Warrant Agent may petition at the expense of the Company to any court of competent jurisdiction for the appointment of a successor to the Warrant Agent. Pending appointment of a successor to such Warrant Agent, either by the Company or by such a court, the duties of the Warrant Agent shall be carried out by the Company. The holders of a majority of the unexercised Warrants shall be entitled at any time to remove the Warrant Agent and appoint a successor to such Warrant Agent. Such successor to the Warrant Agent need not be approved by the Company or the former Warrant Agent. After appointment the successor to the Warrant Agent shall be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Warrant Agent without further act or deed; provided that the former Warrant Agent shall deliver and transfer to the successor to the Warrant Agent any property at the time held by it hereunder and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Failure to give any notice provided for in this Section 13, however, or any defect therein, shall not affect the legality or validity of the appointment of a successor to the Warrant Agent. SECTION 14. REPORTS. (a) Whether or not required by the rules and regulations of the Commission, so long as any Warrants or the Warrant Shares are outstanding, the Company shall make available to the Warrant Agent and the holders of Warrants or Warrant Shares (i) all quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and 10-K if the Company were required to file such Forms, including a "Management's Discussion and Analysis of Financial Condition and Results of Operations" and, with respect to the annual information only, a report thereon by the Company's certified independent accountants and (ii) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports. In addition, whether or not required by the rules and regulations of the Commission, the Company shall file a copy of all such information and reports with the Commission for public availability (unless the Commission shall not accept such a filing) and make such information available to securities analysts and prospective investors upon request. Delivery of such reports, information and documents to the Warrant Agent is for informational purposes only and the Warrant Agent's receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Company's compliance with any of its covenants hereunder (as to which the Warrant Agent is entitled to rely exclusively on Officers' Certificates). (b) The Company shall provide the Warrant Agent with a sufficient number of copies of all such reports that the Warrant Agent may be required to deliver to the holders of the Warrants and the Warrant Shares under this Section 14. SECTION 15. NOTICES TO COMPANY AND WARRANT AGENT.

Any amendment or supplement to this Agreement that has an adverse effect on the interests of the holders of Warrants shall require the written consent of the holders of a majority of the then outstanding Warrants (excluding Warrants held by the Company or any of its affiliates).

A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Warrants may be exercised at any time on or after the opening of business on January 29, 2006 and on or before 5:00 p.m. New York City time on August 1, 2008; provided that holders shall be able to exercise their Warrants only if a registration statement relating to the Warrants Shares is then in effect, or the exercise of such Warrants is exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"), and such securities are qualified for sale or exempt from qualification under the applicable securities laws of the states in which the various holders of the Warrants or other persons to whom it is proposed that the Warrant Shares be issued on exercise of the Warrants reside. In order to exercise all or any of the Warrants represented by this Warrant Certificate, the holder must deliver to the Warrant Agent at its New York corporate trust office set forth in Section 15 of the Warrant Agreement this Warrant Certificate and the form of election to purchase on the reverse hereof duly filled in and signed, which signature shall be medallion guaranteed by an institution which is a member of a Securities Transfer Association recognized signature guarantee program, and upon payment to the Warrant Agent for the account of the Company of the Exercise Price, as adjusted as provided in the Warrant Agreement, for the number of Warrant Shares in respect of which such Warrants are then exercised.

ATC MEXICO HOLDING CORP. 2001 STOCK OPTION PLAN 1. PURPOSE The purpose of this 2001 Stock Option Plan (the "Plan") is to encourage directors, officers and employees of and consultants and other persons providing services to ATC Mexico Holding Corp. (the "Company") and its Affiliates (as hereinafter defined) to continue their association with the Company and its Affiliates, by providing opportunities for such persons to participate in the ownership of the Company and in its future growth through the granting of stock options (the "Options") which may be options designed to qualify as incentive stock options (within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") (an "ISO"), or Options not intended to qualify for any special tax treatment under the Code (a "NQO"). The term "Affiliate" as used in the Plan means a corporation or other business organization which owns in the Company, or in which the Company or any such corporation or other business entity owns, directly or indirectly through an unbroken chain of ownership, fifty percent (50%) or more of the total combined voting power of all classes of stock. 2. ADMINISTRATION OF THE PLAN The Plan shall be administered by a committee (the "Committee") consisting of two or more members of the Company's Board of Directors (the "Board"). The Committee shall from time to time determine to whom options or other rights shall be granted under the Plan, whether options granted shall be ISOs or NQOs, the terms of the options or other rights, and the number of shares that may be granted under options. The Committee shall report to the Board the names of individuals to whom stock or options or other rights are to be granted, the number of shares covered, and the terms and conditions of each grant. The determinations described in this Section 2 may be made by the Committee or by the Board, as the Board shall direct in its sole and absolute discretion, and references in the Plan to the Committee shall be understood to refer to the Board in any such case. The Committee shall select one of its members as Chairman and shall hold meetings at such times and places as it may determine. A majority of the Committee shall constitute a quorum, and acts of the Committee at which a quorum is present, or acts reduced to or approved in writing by all the members of the Committee, shall be the valid acts of the Committee. The Committee shall have the authority to adopt, amend, and rescind such rules and regulations as, in its opinion, may be advisable in the administration of the Plan. All questions of interpretation and application of such rules and regulations, of the Plan and of Options, shall be subject to the determination of the Committee, which shall be final and binding. The Plan shall be administered in such a manner as to permit those Options granted hereunder and specially designated under Section 5 as ISOs to qualify as incentive stock options as described in Section 422 of the Code. For so long as Section 16 of the Securities Exchange Act of 1934, as amended from time to time (the "Exchange Act"), is applicable to the Company, each member of the Committee shall be a "non-employee director" or the equivalent within the meaning of Rule 16b-3 under the Exchange Act, and, for so long as Section 162(m) of the Code is applicable to the Company, an "outside director" within the meaning of Section 162 of the Code and the regulations thereunder. If, however, the Committee is not comprised of two or more "outside directors," then, although the Committee may still administer the Plan, the Compensation Committee of the Board of Directors of American Tower Corporation ("ATC"), so long as it is the parent of the Company, or such other committee that makes grants pursuant to the parent's stock option or similar plan, shall make grants of options or other rights under the Plan (if the - 1 -

Compensation Committee or such committee consists of two or more members who are "outside directors"). With respect to persons subject to Section 16 of the Exchange Act ("Insiders"), transactions under the Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successor under the Exchange Act. To the extent any provision of the Plan or action by the Committee fails to so comply, it shall be deemed to be modified so as to be in compliance with such Rule, or, if such modification is not possible, it shall be deemed to be null and void, to the extent permitted by law and deemed advisable by the Committee. 3. OPTION SHARES The stock subject to Options under the Plan shall be shares of Common Stock, par value $.01 per share (the "Stock"). The total amount of the Stock with respect to which Options may be granted (the "Option Pool"), shall not exceed in the aggregate 360 shares; provided, however, such aggregate number of shares shall be subject to adjustment in accordance with the provisions of Section 17. If an outstanding Option shall expire for any reason or shall terminate by reason of the death or severance of employment of the Optionee, the surrender of any such Option, or any other cause, the shares of Stock allocable to the unexercised portion of such Option may again be subject to an option under the Plan. The maximum number of shares of Stock subject to Options that may be granted to any Optionee in the aggregate in any calendar year shall not exceed 150 shares, subject to adjustment in accordance with the provisions of Section 17. 4. AUTHORITY TO GRANT OPTIONS The Committee may determine, from time to time, which employees of the Company or any Affiliate or other persons shall be granted Options under the Plan, the terms of the Options (including without limitation whether an Option shall be an ISO or a NQO), and the number of shares which may be purchased under the Option or Options. Without limiting the generality of the foregoing, the Committee may from time to time grant: (a) to such employees (other than employees of an Affiliate which is not a corporation) as it shall determine an Option or Options to buy a stated number of shares of Stock under the terms and conditions of the Plan which Option or Options will to the extent so designated at the time of grant constitute an ISO; and (b) to such eligible directors, employees or other persons as it shall determine an Option or Options to buy a stated number of shares of Stock under the terms and conditions of the Plan which Option or Options shall constitute a NQO. Subject only to any applicable limitations set forth elsewhere in the Plan, the number of shares of Stock to be covered by any Option shall be as determined by the Committee. 5. WRITTEN AGREEMENT Each Option granted hereunder shall be embodied in an option agreement (the "Option Agreement") substantially in the form of Exhibit 1, which shall be signed by the Optionee and by a duly authorized officer of the Company for and in the name and on behalf of the Company. An Option Agreement may contain such restrictions on exercisability and such other provisions not inconsistent with the Plan as the Committee in its sole and absolute discretion shall approve. 6. ELIGIBILITY The individuals who shall be eligible for grant of Options under the Plan shall be employees (including officers who may be members of the Board), directors who are not employees and other individuals, whether or not employees, who render services of special importance to the management, - 2 -

operation or development of the Company or an Affiliate, and who have contributed or may be expected to contribute to the success of the Company or an Affiliate. An employee, director or other person to whom an Option has been granted pursuant to an Option Agreement is hereinafter referred to as an "Optionee." 7. OPTION PRICE The price at which shares of Stock may be purchased pursuant to an Option shall be specified by the Committee at the time the Option is granted, but shall in no event be less than the par value of such shares and, in the case of an ISO, except as set forth in the following sentence, one hundred percent (100%) of the fair market value of the Stock on the date the ISO is granted. In the case of an employee who owns (or is considered under Section 424(d) of the Code as owning) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Affiliate, the price at which shares of Stock may be so purchased pursuant to an ISO shall be not less than one hundred and ten percent (110%) of the fair value of the Stock on the date the ISO is granted. For purposes of the Plan, the "fair market value" of a share of Stock on any date specified herein, shall mean (a) the last reported sales price, regular way, or, in the event that no sale takes place on such day, the average of the reported closing bid and asked prices, regular way, in either case (i) as reported on the New York Stock Exchange Composite Tape, or (ii) if the Stock is not listed or admitted to trading on the New York Stock Exchange, on the principal national securities exchange on which such security is listed or admitted to trading, or (iii) if not then listed or admitted to trading on any national securities exchange, on the NASDAQ National Market System; or (b) if the Stock is not quoted on such National Market System, (i) the average of the closing bid and asked prices on each such day in the over-the-counter market as reported by NASDAQ, or (ii) if bid and asked prices for such security on each such day shall not have been reported through NASDAQ, the average of the bid and asked prices for such day as furnished by any New York Stock Exchange member firm regularly making a market in such security selected for such purpose by the Committee; or (c) if the Stock is not then listed or admitted to trading on any national exchange or quoted in the over-the-counter market, the fair value thereof will be based on the Company Value; provided, however, that any method of determining fair market value employed by the Committee with respect to an ISO shall be consistent with any applicable laws or regulations pertaining to "incentive stock options". 8. DURATION OF OPTIONS The duration of any Option shall be specified by the Committee in the Option Agreement, but no Option shall be exercisable after the expiration of ten (10) years from the date such Option is granted. In the case of any employee who owns (or is considered under Section 424(d) of the Code as owning) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Affiliate, no ISO shall be exercisable after the expiration of five (5) years from the date such Option is granted. The Committee, in its sole and absolute discretion, may extend any Option theretofore granted. 9. VESTING PROVISIONS Each Option may be exercised so long as it is valid and outstanding from time to time, in part or as a whole, in such manner and subject to such conditions as the Committee, in its sole and absolute discretion, may provide in the Option Agreement. The Committee may, in its sole and absolute discretion, accelerate Options, in whole or in part, on such terms and conditions as the Committee may, in its sole and absolute discretion, determine. - 3 -

10. EXERCISE OF OPTIONS Options shall be exercised by the delivery of written notice to the Company setting forth the number of shares of Stock with respect to which the Option is to be exercised, accompanied by payment of the option price of such shares, which payment shall be made, subject to the alternative provisions of this Section, in cash or by such cash equivalents, payable to the order of the Company in an amount in United States dollars equal to the option price of such shares, as the Committee in its sole and absolute discretion shall consider acceptable. Such notice shall be delivered in person to the Secretary of the Company or shall be sent by registered mail, return receipt requested, to the Secretary of the Company, in which case delivery shall be deemed made on the date such notice is deposited in the mail. Alternatively, if the Option Agreement so specifies, and subject to such rules as may be established by the Committee, payment of the option price may be made through a so-called "cashless exercise" procedure, under which the Optionee shall deliver irrevocable instructions to a broker to sell shares of Stock acquired upon exercise of the Option and to remit promptly to the Company a sufficient portion of the sale proceeds to pay the option price and any tax withholding resulting from such exercise. Alternatively, payment of the option price may be made, in whole or in part, in shares of Stock owned by the Optionee; provided, however, that the Optionee may not make payment in shares of Stock that he acquired upon the earlier exercise of any ISO (or other "incentive stock option"), unless and until he has held the shares until at least two (2) years after the date the ISO (or such other incentive stock option) was granted and at least one (1) year after the date the ISO (or such other option) was exercised. If payment is made in whole or in part in shares of Stock, then the Optionee shall deliver to the Company in payment of the option price of the shares with respect of which such Option is exercised (a) certificates registered in the name of such Optionee representing a number of shares of Stock legally and beneficially owned by such Optionee, free of all liens, claims and encumbrances of every kind, and having a fair market value on the date of delivery of such notice equal to the option price of the shares of Stock with respect to which such Option is to be exercised, such certificates to be accompanied by stock powers duly endorsed in blank by the record holder of the shares of Stock represented by such certificates; and (b) if the option price of the shares with respect to which such Option is to be exercised exceeds such fair market value, cash or such cash equivalents payable to the order to the Company, in an amount in United States dollars equal to the amount of such excess, as the Committee in its sole and absolute discretion shall consider acceptable. Notwithstanding the foregoing provisions of this Section, the Committee, in its sole and absolute discretion, (i) may refuse to accept shares of Stock in payment of the option price of the shares of Stock with respect to which such Option is to be exercised and, in that event, any certificates representing shares of Stock which were delivered to the Company with such written notice shall be returned to such Optionee together with notice by the Company to such Optionee of the refusal of the Committee to accept such shares of Stock and (ii) may accept, in lieu of actual delivery of stock certificates, an attestation by the Optionee substantially in the form attached herewith as Exhibit C or such other form as may be deemed acceptable by the Committee that he or she owns of record the shares to be tendered free and clear of all liens, claims and encumbrances of every kind. Alternatively, payment of the option price may be made in whole or in part by a full recourse promissory note executed by the Optionee and containing the following terms and conditions (and such others as the Committee shall, in its sole and absolute discretion, determine from time to time): (a) it shall be collaterally secured, pursuant to a pledge agreement in form and scope satisfactory to the Committee, by the shares of Stock obtained upon exercise of the Option and other collateral satisfactory to the Committee which other collateral shall be in an amount equal to not less than 100% of the principal amount of the note; (b) repayment shall be made no later than three (3) years from the date of exercise; and (c) the note shall bear interest at a market rate as determined by the Committee, payable monthly out of a payroll deduction provision; provided, however, that notwithstanding the foregoing (i) an amount not - 4 -

less than the par value of the shares of Stock with respect to which the Option is being exercised must be paid in cash, cash equivalents, or shares of Stock in accordance with this Section, and (ii) the payment of such exercise price by promissory note does not violate any applicable laws or regulations, including, without limitation, Delaware corporate law or applicable margin lending rules or result in a compensation expense to the Company or any Affiliate of the Company for financial reporting purposes. As promptly as practicable after the receipt by the Company of (a) written notice from the Optionee setting forth the number of shares of Stock with respect to which such Option is to be exercised and (b) payment of the option price of such shares in the form required by the foregoing provisions of this Section, the Company shall cause to be delivered to such Optionee certificates representing the number of shares with respect to which such Option has been so exercised (less a number of shares equal to the number of shares as to which ownership was attested under the procedure described in clause (ii) of the next preceding paragraph). 11. TRANSFERABILITY OF OPTIONS Options shall not be transferable by the Optionee otherwise than by will or under the laws of descent and distribution, and shall be exercisable during his or her lifetime only by the Optionee, except that the Committee may, subject to such conditions as it shall, in its sole and absolute discretion, determine, specify in an Option Agreement that pertains to an NQO that the Optionee may transfer such NQO to a member of the Immediate Family of the Optionee, to a trust solely for the benefit of the Optionee and the Optionee's Immediate Family, or to a partnership or limited liability company whose only partners or members are the Optionee and members of the Optionee's Immediate Family. "Immediate Family" shall mean, with respect to any Optionee, such Optionee's child, stepchild, grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, and shall include adoptive relationships. 12. TERMINATION OF EMPLOYMENT OR INVOLVEMENT OF OPTIONEE WITH THE COMPANY For purposes of this Section, employment by or involvement with (in the case of an Optionee who is not an employee) an Affiliate shall be considered employment by or involvement with the Company. Except as otherwise set forth in the Option Agreement, after the Optionee's termination of employment with the Company other than by reason of death or disability, including his retirement in good standing from the employ of the Company for reasons of age under the then established rules of the Company, the Option shall terminate on the earlier of the date of its expiration or three (3) months after the date of such termination or retirement. After the death of the Optionee, his or her executors, administrators or any persons to whom his or her Option may be transferred by will or by the laws of descent and distribution shall have the right to exercise the Option to the extent to which the Optionee was entitled to exercise the Option. The Committee may, subject to such conditions as it shall, in its sole and absolute discretion, determine, specify in an Option Agreement that, in the event that such termination is a result of disability, the Optionee shall have the right to exercise the Option pursuant to its terms as if such Optionee continued as an employee. Authorized leave of absence or absence on military or government service shall not constitute severance of the employment relationship between the Company and the Optionee for purposes of the Plan, provided that either (a) such absence is for a period of no more than ninety (90) days or (b) the Employee's right to re-employment after such absence is guaranteed either by law or by contract. - 5 -

For Optionees who are not employees of the Company, options shall be exercisable for such periods following the termination of the Optionee's involvement with the Company as may be set forth in the Option Agreement. 13. REQUIREMENTS OF LAW The Company shall not be required to sell or issue any shares of Stock upon the exercise of any Option if the issuance of such shares shall constitute or result in a violation by the Optionee or the Company of any provisions of any law, statute or regulation of any governmental authority. Specifically, in connection with the Securities Act of 1933, as amended (the "Securities Act"), and any applicable state securities or "blue sky" law (a "Blue Sky Law"), upon exercise of any Option the Company shall not be required to issue such shares unless the Committee has received evidence satisfactory to it to the effect that the holder of such Option will not transfer such shares except pursuant to a registration statement in effect under the Securities Act and Blue Sky Laws or unless an opinion of counsel satisfactory to the Company has been received by the Company to the effect that such registration and compliance is not required. Any determination in this connection by the Committee shall be final, binding and conclusive. The Company shall not be obligated to take any action in order to cause the exercise of an Option or the issuance of shares of Stock pursuant thereto to comply with any law or regulations of any governmental authority, including, without limitation, the Securities Act or applicable Blue Sky Law. Notwithstanding any other provision of the Plan to the contrary, the Company may refuse to permit transfer of shares of Stock if in the opinion of its legal counsel such transfer would violate federal or state securities laws or subject the Company to liability thereunder. Any sale, assignment, transfer, pledge or other disposition of shares of Stock received upon exercise of any Option (or any other shares or securities derived therefrom) which is not in accordance with the provisions of this Section shall be void and of no effect and shall not be recognized by the Company. Legend on Certificates. The Committee may cause any certificate representing shares of Stock acquired upon exercise of an Option (and any other shares or securities derived therefrom) to bear a legend to the effect that the securities represented by such certificate have not been registered under the Securities Act of 1933, as amended, or any applicable state securities laws, and may not be sold, assigned, transferred, pledged or otherwise disposed of except in accordance with the Plan and applicable agreements binding the holder and the Company or any of its stockholders. 14. NO RIGHTS AS STOCKHOLDER No Optionee shall have any rights as a stockholder with respect to shares covered by his or her Option until the date of issuance of a stock certificate for such shares; except as otherwise provided in Section 17, no adjustment for dividends or otherwise shall be made if the record date therefor is prior to the date of issuance of such certificate. 15. EMPLOYMENT OBLIGATION The granting of any Option shall not impose upon the Company or any Affiliate any obligation to employ or continue to employ any Optionee, or to engage or retain the services of any person, and the right of the Company or any Affiliate to terminate the employment or services of any person shall not be diminished or affected by reason of the fact that an Option has been granted to him or her. The existence of any Option shall not be taken into account in determining any damages relating to termination of employment or services for any reason. - 6 -

16. CERTAIN RIGHTS OF THE COMPANY (a) Voluntary or Involuntary Transfers of Stock. The voluntary or involuntary transfer of shares of Stock acquired by an Optionee pursuant to the exercise of an Option or Options granted under the Plan is subject to the provisions of the Stockholder Agreement. (b) Termination of Employment or Involvement. If the Optionee's employment by or involvement with the Company (including, for this purpose, any Affiliate) shall terminate because of (x) the death or Disability of Optionee, (y) a Wrongful Termination, or (z) a Forfeiture Event, the Company shall have the assignable right to repurchase all but not less than all of the shares of Stock (or other shares or securities derived therefrom) acquired pursuant to the exercise of an Option at a price equal to the Put/Call Price at the time of such repurchase. In addition, if at the time of such termination an Optionee holds an Option granted under the Plan which is by its terms exercisable after such termination, the Company shall have the assignable right to repurchase all but not less than all of the shares of Stock acquired pursuant to the exercise of such Option, at the Put/Call Price at the time of such repurchase. If the option price for any repurchased shares has been paid by the Optionee's promissory note pursuant to Section 10, then the repurchase price for such shares of Stock shall be first applied to the repayment of the outstanding amount, if any, due under such note in respect of the repurchased shares, and any accrued but unpaid interest thereon. The Company's right to repurchase shares of Stock (or other shares or securities) may be exercised at any time not earlier than one hundred and eighty (180) days following the exercise of the Option with respect to the shares of Stock (or other shares or securities) to be repurchased, and not later than three hundred and sixty-five (365) days following the date of (i) the Optionee's termination of employment or involvement or (ii) in the case of a repurchase of shares of Stock (or other shares or securities) acquired pursuant to the exercise of an Option subsequent to such termination, such exercise. Any such shares of Stock (or other shares or securities) as to which the Company does not exercise its repurchase rights within such period shall thereafter be free of the foregoing restrictions, but subject, however, to the provisions of the Stockholder Agreement. 17. CHANGES IN THE COMPANY'S CAPITAL STRUCTURE The existence of outstanding Options shall not affect in any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations or other changes in the Company's capital structure or its business or any merger or consolidation of the Company or any issue of bonds, debentures, preferred or preference stock, whether or not convertible into the Stock or other securities, ranking prior to the Stock or affecting the rights thereof, or warrants, rights or options to acquire the same, or the dissolution or liquidation of the Company or any sale or transfer of all or any part of its assets or business or any other corporate act or proceeding, whether of a similar character or otherwise. The number of shares of Stock in the Option Pool (less the number of shares theretofore delivered upon exercise of Options) and the number of shares of Stock covered by any outstanding Option and the price per share payable upon exercise thereof (provided that in no event shall the option price be less than the par value of such shares) shall be proportionately adjusted for any increase or decrease in the number of issued and outstanding shares of Stock resulting from any subdivision, split, combination or consolidation of shares of Stock or the payment of a dividend on the Stock in shares of Stock or other securities of the Company. The decision of the Board as to the adjustment, if any, required by the provisions of this Section shall be final, binding and conclusive. If the Company merges or consolidates with a wholly-owned subsidiary for the purpose of reincorporating itself under the laws of another jurisdiction, the Optionees will be entitled to acquire shares of Stock of the reincorporated Company upon the same terms and conditions as were in effect immediately prior to such reincorporation (unless such reincorporation involves a change in the number of shares or the capitalization of the Company, in which case proportional adjustments shall be made as - 7 -

provided above) and the Plan, unless otherwise rescinded by the Board, will remain the Plan of the reincorporated Company. Except as otherwise provided in the preceding paragraph, if the Company is merged or consolidated with another corporation, whether or not the Company is the surviving entity, or if the Company is liquidated or sells or otherwise disposes of all or substantially all of its assets to another entity while unexercised Options remain outstanding under the Plan, or if other circumstances occur in which the Board in its sole and absolute discretion deems it appropriate for the provisions of this paragraph to apply (in each case, an "Applicable Event"), then (a) each holder of an outstanding Option shall be entitled, upon exercise of such Option, to receive in lieu of shares of Stock, such stock or other securities or property as he or she would have received had he exercised such option immediately prior to the Applicable Event; (b) the Board may, in its sole and absolute discretion, waive, generally or in one or more specific cases, any limitations imposed pursuant to Section 9 so that some or all Options from and after a date prior to the effective date of such Applicable Event, specified by the Board, in its sole and absolute discretion, shall be exercisable in full or in part; (c) the Board may, in its sole and absolute discretion, cancel all outstanding and unexercised Options as of the effective date of any such Applicable Event; (d) the Board may, in its sole discretion, convert some or all Options into options to purchase the stock or other securities of the surviving corporation pursuant to an Applicable Event; or (e) the Board may, in its sole and absolute discretion, assume the outstanding and unexercised options to purchase stock or other securities of any corporation and convert such options into Options to purchase Stock, whether pursuant to this Plan or not, pursuant to an Applicable Event; provided, however, in the case of any such cancellation pursuant to clause (c), (i) notice shall be given to each holder of an Option not less than thirty (30) days preceding the effective date of such Applicable Event, and (ii) all such outstanding and unexercised Options shall immediately vest, to the extent that were not so vested so that such Options shall be exercisable in full during such thirty (30) day period. Except as expressly provided herein, the issue by the Company of shares of Stock or other securities of any class or series or securities convertible into or exchangeable or exercisable for shares of Stock or other securities of any class or series for cash or property or for labor or services either upon direct sale or upon the exercise of rights or warrants to subscribe therefor, or upon conversion of shares or obligations of the Company convertible into such shares or other securities, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number, class or price of shares of Stock then subject to outstanding Options. 18. AMENDMENT OR TERMINATION OF PLAN The Board may, in its sole and absolute discretion, modify, revise or terminate the Plan at any time and from time to time; provided, however, that without the further approval of the holders of at least a majority of the outstanding shares of Stock, the Board may not change the aggregate number of shares of Stock which may be issued under Options pursuant to the provisions of the Plan either to any one person or in the aggregate; or change the class of persons eligible to receive ISOs. Notwithstanding the preceding sentence, the Board shall in all events have the power and authority to make such changes in the Plan and in the regulations and administrative provisions hereunder or in any outstanding Option as, in the opinion of counsel for the Company, may be necessary or appropriate from time to time to enable any Option granted pursuant to the Plan to qualify as an ISO or such other stock option as may be defined under the Code, as amended from time to time, so as to receive preferential federal income tax treatment. 19.

Accordingly, as a condition to its participation in the Registered Exchange offer, each Holder participating in the Registered Exchange Offer shall be required to represent to the Company in the Letter of Transmittal in the Registered Exchange Offer or by other means that, at the time of the consummation of the Registered Exchange Offer: (i) any New Securities received by such Holder will be acquired in the ordinary course of business; (ii) such Holder will have no arrangement or understanding with any Person to participate in the distribution of the Securities or the New Securities within the meaning of the Act; and (iii) such Holder is not an Affiliate of the Company or any of the Guarantors.

Shelf Registration. If (A): (i) due to any change in law or applicable interpretations thereof by the Commission's staff, the Company and the Guarantors determine upon advice of its outside counsel that it is not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof, or (ii) for any other reason the Registered Exchange Offer is not consummated within 30 business days (or such longer period as required by applicable law) of the Effectiveness Target Date (or, if such 30 business days is not a Business Day, the next succeeding Business Day) or the Exchange Offer Registration Statement is not declared effective within 180 days of the Issue Date (or if such 180/th/ day is not a Business Day, the next succeeding Business Day); or (B) any Holder of Transfer Restricted Securities notifies the Company prior to the 20/th/ day following the consummation of the Registered Exchange Offer that: (i) it is prohibited by law or policy of the Commission from participating in the Registered Exchange Offer; (ii) it may not resell the New Securities acquired by it in the Registered Exchange Offer to the public without delivering a prospectus and the prospectus contained in the Registered Exchange Offer is not appropriate or available for such resales or (iv) that it is a 7

Broker-Dealer and owns Securities acquired directly from the Company or an affiliate of the Company, the Company and the Guarantors shall effect a Shelf Registration Statement in accordance with subsection (b) below. (a) (i) The Company and the Guarantors shall as promptly as practicable (but in no event more than 30 business days after so required or requested pursuant to this Section 3 (or, if such 30/th/ day is not a Business Day, the next succeeding Business Day)), file with the Commission and thereafter (but in no event more than 180 days after the date the Company was required or requested to make such filing pursuant to this Section 3 (or, if such 180/th/ day is not a Business Day, the next succeeding Business Day)) use their reasonable best efforts to cause to be declared effective under the Act a Shelf Registration Statement relating to the offer and sale of the Securities or the New Securities, as applicable, by the Holders thereof from time to time in accordance with the methods of distribution elected by such Holders and set forth in such Shelf Registration Statement; provided, however, that no Holder (other than a Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder; and provided further, that with respect to New Securities received by a Purchaser in exchange for Securities constituting any portion of an unsold allotment, the Company and the Guarantors may, if permitted by current interpretations by the Commission's staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Item 507 or 508 of Regulation S-K, as applicable, in satisfaction of its obligations under this subsection with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement. Notwithstanding anything in this Section 3, Liquidated Damages shall accrue only in accordance with the provisions of Section 6 hereof. (ii) The Company and the Guarantors shall use their reasonable best efforts to keep the Shelf Registration Statement continuously effective, supplemented and amended as required by the Act, in order to permit the Prospectus forming part thereof to be usable by Holders from the date the Shelf Registration Statement is declared effective by the Commission until the earlier of: (i) such date as all the Securities covered by the Shelf Registration Statement have been sold, or (ii) the date on which all of the Securities held by persons that are not Affiliates of the Company or the Guarantors may be resold without registration pursuant to Rule 144(k) under the Act (such period being called the "Shelf Registration Period"). The Company and the Guarantors shall be deemed not to have used their reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless (A) such action is required by applicable law; or (B) such action is taken by the Company and the Guarantors in good faith and for valid business reasons (not including avoidance of the Company's and the Guarantors' obligations hereunder), including the acquisition or divestiture of assets, a merger or financing so long as the Company and the Guarantors promptly thereafter complies with the requirements of Section 4(k) hereof, if applicable. (b) Not less than 30 calendar days prior to the Effective Time of any Shelf Registration Statement required under this Agreement, the Company and the Guarantors shall mail the Notice and Questionnaire (the "Notice and Questionnaire") substantially in the form 8

attached as Annex E hereto to the Holders of Transfer Restricted Securities; no Holder shall be entitled to be named as a selling securityholder in the Shelf Registration Statement as of the Effective Time, and no Holder shall be entitled to use the prospectus forming a part thereof for resales of Securities at any time, unless such Holder has returned a completed and signed Notice and Questionnaire to the Company by the deadline for response set forth therein; provided, however, that holders of Transfer Restricted Securities shall have at least 28 calendar days from the date on which the Notice and Questionnaire is first mailed to such Holders to return a completed and signed Notice and Questionnaire to the Company. (c) After the Effective Time of any Shelf Registration Statement required to be filed under this Agreement, Holders of Transfer Restricted Securities who did not timely return a Notice and Questionnaire to the Company may return a Notice and Questionnaire at any time and may request to be included in such Shelf Registration Statement. If: (i) the Company and the Guarantors can include such Holder with respect to its Transfer Restricted Securities by means of a prospectus supplement filed pursuant to Rule 424(b) of the Act or by means of a registration statement filed pursuant to Rule 462(b) of the Act, then the Company and the Guarantors shall file such Rule 424(b) supplement or Rule 462(b) registration statement with the Commission within 10 Business Days of its receipt of the Notice and Questionnaire; (ii) the Company and the Guarantors, in the opinion of its counsel, cannot include such Holder with respect to its Transfer Restricted Securities by means of a prospectus supplement to the prospectus contained as part of such effective Shelf Registration Statement or by means of a related registration statement filed pursuant to Rule 462(b) of the Act, the Company and the Guarantors shall promptly take any action reasonably necessary to enable such a Holder to use a registration statement for resale of Transfer Restricted Securities, including, without limitation, any action necessary to identify such Holders or selling securityholder in a new Shelf Registration Statement which the Company and the Guarantors shall promptly file and cause to be declared effective to cover the resale of the Transfer Restricted Securities that are the subject of such request. (d) In the event of a Shelf Registration Statement, in addition to the information required to be provided in the Notice and Questionnaire, the Company may require Holders to furnish to the Company additional information regarding such Holder and such Holder's intended method of distribution of Securities as may be required in order to comply with the Securities Act. Each Holder agrees to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Holder to the Company or of the occurrence of any event in either case as a result of which any prospectus relating to the Shelf Registration Statement contains or would contain an untrue statement of a material fact regarding such Holder or such Holder's intended method of disposition of such Securities or omits to state any material fact regarding such Holder or such Holder's intended method of disposition of such Securities required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any such required additional information so that such prospectus shall not contain, with respect to such Holder or the disposition of such Securities, an untrue statement of a material fact or omit 9

to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. 4. Additional Registration Procedures.

(g) The Company and the Guarantors shall furnish to each Exchanging Dealer which so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including all material incorporated by reference therein, and, if the Exchanging Dealer so requests in writing, all exhibits thereto (including exhibits incorporated by reference therein). (h) The Company and the Guarantors shall promptly deliver to each Purchaser, each Exchanging Dealer and each other Person required to deliver a Prospectus during the Exchange Offer Registration Period, without charge, as many copies of the Prospectus included in such Exchange Offer Registration Statement and any amendment or supplement thereto as any such Person may reasonably request. The Company and the Guarantors consent to the use of the Prospectus or any amendment or supplement thereto by any Purchaser, any Exchanging Dealer and any such other Person that may be required to deliver a Prospectus following the Registered Exchange Offer in connection with the offering and sale of the New Securities covered by the Prospectus, or any amendment or supplement thereto, included in the Exchange Offer Registration Statement. (i) Prior to the Registered Exchange Offer or any other offering of Securities pursuant to any Registration Statement, the Company shall arrange, if necessary, for the qualification of the Securities or the New Securities for sale under the laws of such jurisdictions as any Holder shall reasonably request and will maintain such qualification in effect so long as required; provided that in no event shall the Company or any of the Guarantors be obligated to qualify to do business in any jurisdiction where it is not then so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the Initial Placement, the Registered Exchange Offer or any offering pursuant to a Shelf Registration Statement, in any such jurisdiction where it is not then so subject or otherwise subject itself to taxation in any such jurisdiction. (j) The Company and the Guarantors shall cooperate with the Holders of Securities to facilitate the timely preparation and delivery of certificates representing New Securities or Securities to be issued or sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such names as Holders may request. (k) Upon the occurrence of any event contemplated by subsections (c)(ii) through (v) above, the Company and the Guarantors shall promptly prepare a post-effective amendment to the applicable Registration Statement or an amendment or supplement to the related Prospectus or file any other required document so that, as thereafter delivered to 12

Purchasers of the securities included therein, the Prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company and the Guarantors may delay preparing, filing and distributing any such supplements or amendments (and continue the suspension of the use of the prospectus) if the Company and the Guarantors determine in good faith that such supplement or amendment would, in the reasonable judgment of the Company and the Guarantors, (i) interfere with or affect the negotiation or completion of a transaction that is being contemplated by the Company and the Guarantors (whether or not a final decision has been made to undertake such transaction) or (ii) involve initial or continuing disclosure obligations that are not in the best interests of the Company's or the Guarantors' shareholders at such time; provided, further, that neither such delay nor such suspension with respect to all matters in clause (i) or (ii) shall extend for a period of more than 30 days in any three-month period or more than 90 days for all such periods in any twelve-month period and shall not affect the Company's and the Guarantors' obligations to pay Liquidated Damages as contemplated by Section 6 hereof. (l) In such circumstances, the period of effectiveness of the Exchange Offer Registration Statement provided for in Section 2 and the Shelf Registration Statement provided for in Section 3(b) shall each be extended by the number of days from and including the date of the giving of a notice of suspension pursuant to Section 4(c) to and including the date when the Purchasers, the Holders of the Securities and any known Exchanging Dealer shall have received such amended or supplemented Prospectus pursuant to this Section. (m) Not later than the effective date of any Registration Statement, the Company and the Guarantors shall provide CUSIP numbers for the Securities or the New Securities, as the case may be, registered under such Registration Statement and provide the Trustee with printed certificates for such Securities or New Securities, in a form eligible for deposit with The Depository Trust Company. (n) The Company and the Guarantors shall comply with all applicable rules and regulations of the Commission and shall make generally available to its security holders no later than 45 days after the end of any 12-month period (or 90 days after the end of any 12-month period if such period is a fiscal year), an earnings statement satisfying the provisions of Section 11(a) of the Act and Rule 158 thereunder (or any similar rule under the Act) for a period of at least 12 months beginning on the first day of the first fiscal quarter after the effective date of the applicable Registration Statement. (o) The Company and the Guarantors shall cause the Indenture or the New Securities Indenture, as the case may be, to be qualified under the Trust Indenture Act in a timely manner. (p) The Company and the Guarantors may require each Holder of securities to be sold pursuant to any Shelf Registration Statement to furnish to the Company and the Guarantors such information regarding the Holder and the distribution of such securities as the Company and the Guarantors may from time to time reasonably require for inclusion in such Registration Statement. The Company and the Guarantors may exclude from such Shelf 13

Registration Statement the Securities of any Holder that fails to furnish such information within a reasonable time after receiving such request. (q) In the case of any Shelf Registration Statement, the Company and the Guarantors shall enter into such agreement and take all other appropriate actions (including if requested an underwriting agreement in customary form) in order to expedite or facilitate the registration or the disposition of the Securities, and in connection therewith, if an underwriting agreement is entered into, cause the same to contain indemnification provisions and procedures no less favorable than those set forth in Section 7 (or such other provisions and procedures acceptable to the Majority Holders and the Managing Underwriters, if any, with respect to all parties to be indemnified pursuant to Section 7). (r) In the case of any Shelf Registration Statement, the Company and the Guarantors shall: (i) make reasonably available for inspection by the Holders of Securities to be registered thereunder, any underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by the Holders or any such underwriter all relevant and reasonably requested financial and other records, pertinent corporate documents and properties of the Company and its subsidiaries; (ii) cause the Company's and the Guarantors' officers, directors and employees to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or agent in connection with any such Registration Statement as is customary for similar due diligence examinations; provided, however, that any information that is designated in writing by the Company or the Guarantors, in good faith, as confidential at the time of delivery of such information shall be kept confidential by the Holders or any such underwriter, attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality; (iii) make such representations and warranties to the Holders of Securities registered thereunder and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement; (iv) obtain opinions of counsel to the Company and the Guarantors and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to the Managing Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Holders and underwriters; 14

(v) obtain "cold comfort" letters and updates thereof from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed to each selling Holder of Securities registered thereunder and the underwriters, if any, who have provided such accountants with a representation letter if required to do so under Statement on Auditing Standards No. 72 in customary form and covering matters of the type customarily covered in "cold comfort" letters in connection with primary underwritten offerings; (vi) deliver such documents and certificates as may be reasonably requested by the Majority Holders and the Managing Underwriters, if any, including those to evidence compliance with Section 4(k) and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company and the Guarantors; and (vii) after the Effective Time of the Shelf Registration Statement, upon the request of any Holder, promptly send a Notice and Questionnaire to such Holder; provided neither that the Company nor the Guarantors shall be required to take any action to name such Holder as a selling securityholder in the Shelf Registration Statement or to enable such holder to use the prospectus forming a part thereof for resales of Securities except in accordance with Section 3(c) hereof. The actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall be performed at (A) the effectiveness of such Registration Statement and each post-effective amendment thereto; and (B) each closing under any underwriting or similar agreement as and to the extent required thereunder. (s) In the case of any Exchange Offer Registration Statement, the Company and the Guarantors shall: (i) make reasonably available for inspection by each Purchaser, and any attorney, accountant or other agent retained by such Purchaser, all relevant financial and other records, pertinent corporate documents and properties of the Company, the Guarantors and their respective subsidiaries; (ii) cause the Company's and the Guarantors' officers, directors and employees to supply all relevant information reasonably requested by such Purchaser or any such attorney, accountant or agent in connection with any such Registration Statement as is customary for similar due diligence examinations; provided, however, that any information that is designated in writing by the Company or the Guarantors, in good faith, as confidential at the time of delivery of such information shall be kept confidential by such Purchaser or any such attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality; 15

(iii) make such representations and warranties to such Purchaser, in form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement; (iv) obtain opinions of counsel to the Company and the Guarantors and updates thereof (which counsel and opinions (in form, scope and substance) shall be reasonably satisfactory to such Purchaser and its counsel, addressed to such Purchaser, covering such matters as are customarily covered in opinions requested in underwritten offerings and such other matters as may be reasonably requested by such Purchaser or its counsel; (v) obtain "cold comfort" letters and updates thereof from the independent certified public accountants of the Company and the Guarantors (and, if necessary, any other independent certified public accountants of any subsidiary of the Company or the Guarantors or of any business acquired by the Company for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed to such Purchaser, in customary form and covering matters of the type customarily covered in "cold comfort" letters in connection with primary underwritten offerings as permitted by Statement on Auditing Standards No. 72, or if requested by such Purchaser or its counsel in lieu of a "cold comfort" letter, an agreed-upon procedures letter under Statement on Auditing Standards No. 35, covering matters requested by such Purchaser or its counsel; and (vi) deliver such documents and certificates as may be reasonably requested by such Purchaser or its counsel, including those to evidence compliance with Section 4(k) and with conditions customarily contained in underwriting agreements. The foregoing actions set forth in clauses (iii), (iv), (v), and (vi) of this Section shall be performed at the close of the Registered Exchange Offer and the effective date of any post-effective amendment to the Exchange Offer Registration Statement. (t) If a Registered Exchange Offer is to be consummated, upon delivery of the Securities by Holders to the Company (or to such other Person as directed by the Company) in exchange for the New Securities, the Company shall mark, or caused to be marked, on the Securities so exchanged that such Securities are being canceled in exchange for the New Securities. In no event shall the Securities be marked as paid or otherwise satisfied. (u) The Company and the Guarantors will use their reasonable best efforts (i) if the Securities have been rated prior to the initial sale of such Securities, to confirm such ratings will apply to the Securities or the New Securities, as the case may be, covered by a Registration Statement; or (ii) if the Securities were not previously rated, to cause the Securities covered by a Registration Statement to be rated with at least one nationally recognized statistical rating agency, if so requested by Majority Holders with respect to the related Registration Statement or by any Managing Underwriters. 16

(v) In the event that any Broker-Dealer shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or "assist in the distribution" (within the meaning of the Rules of Fair Practice and the By-Laws of the National Association of Securities Dealers, Inc.) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, assist such Broker-Dealer in complying with the requirements of such Rules and By-Laws, including, without limitation, by: (i) if such Rules or By-Laws shall so require, engaging a "qualified independent underwriter" (as defined in such Rules) to participate in the preparation of the Registration Statement, to exercise usual standards of due diligence with respect thereto and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities; (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 7 hereof; and (iii) providing such information to such Broker-Dealer as may be required in order for such Broker-Dealer to comply with the requirements of such Rules. (w) The Company and the Guarantors shall use their reasonable best efforts to take all other steps necessary to effect the registration of the Securities or the New Securities, as the case may be, covered by a Registration Statement. 5. Registration Expenses. The Company and the Guarantors shall bear all expenses incurred in connection with the performance of its obligations under Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the reasonable fees and disbursements of one firm or counsel designated by the Majority Holders to act as counsel for the Holders in connection therewith, and, in the case of any Exchange Offer Registration Statement, will reimburse the Purchasers for the reasonable fees and disbursements of one firm or counsel acting in connection therewith. Notwithstanding the foregoing, the Holders shall pay all agency fees and commissions and underwriting discounts and commissions and the fees and disbursements of any counsel or other advisors or experts retained by such Holders (severally or jointly), other than the counsel specifically referred to above. 6. Liquidated Damages Under Certain Circumstances. The Company, the Guarantors, the Purchasers and each Holder of Transfer Restricted Securities agree by acquisition of such Securities that the Holders of Transfer Restricted Securities will suffer damages if a Registration Default (as defined below) occurs and that it would not be feasible to ascertain the extent of such damages with precision. Accordingly, the Company, the Guarantors, the Purchasers and each Holder of Transfer Restricted Securities agree that the following Liquidated Damages provisions shall constitute liquidated damages in the event of a "Registration Default" (as defined below) and shall constitute the sole remedy of the Purchasers and each Holder of Transfer Restricted Securities for any Registration Defaults. 17

(a) In accordance with the terms of the Securities, liquidated damages ("Liquidated Damages") with respect to the Securities and New Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a "Registration Default"): (i) on or prior to the 90/th/ day following the Issue Date (or such longer period as required by applicable law), neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been filed with the Commission; (ii) on or prior to the 180/th/ day following the Issue Date (or such longer period as required by applicable law) ( the "Effectiveness Target Date"), neither the Exchange Offer Registration Statement nor the Shelf Registration Statement has been declared effective; (iii) on or prior to 30 business days (or such longer period as required by applicable law) following the Effectiveness Target Date, the Registered Exchange Offer has not been consummated; or (iv) any Registration Statement required by this Agreement has been declared effective by the Commission but (A) such Registration Statement thereafter ceases to be effective or (B) such Registration Statement or the related prospectus ceases to be usable in connection with resales of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related prospectus forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, or (2) it shall be necessary to amend such Registration Statement or supplement the related prospectus, to comply with the Act or the Exchange Act or the respective rules thereunder; Each of the foregoing shall constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or the Guarantors or pursuant to operation of law or as a result of any action or inaction by the Commission; provided, however, that the Company and the Guarantors shall in no event be required to pay liquidated damages for more than one Registration Default at any given time. Liquidated Damages shall be assessed on the Securities or New Securities, from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults shall have been cured, at a rate of $.05 per week per $1,000 of Accreted Value of notes held (the "Liquidated Damages Amount") for the first 90-day period immediately following the occurrence of such Registration Default. The Liquidated Damages Amount will increase by an additional $.05 per week per $1,000 of Accreted Value of notes with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of Liquidated Damages for all Registration Defaults of $.50 per week per $1,000 of Accreted Value of notes. 18

(b) Any amounts of Liquidated Damages due pursuant to Section 6(a) shall be paid to the Holders entitled thereto on February 1 and August 1 of any given year as more fully set forth in the Indenture and the Notes. 7. Indemnification and Contribution. (a) The Company and the Guarantors, jointly and severally, agree to indemnify and hold harmless each Holder of Securities or New Securities, as the case may be, covered by any Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each such Holder and each Person who controls any such Holder within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any preliminary Prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that neither the Company nor the Guarantors will be liable in any case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company and the Guarantors may otherwise have. The Company also agrees to indemnify or contribute as provided in Section 7(d) to Losses of any underwriter of Securities or New Securities, as the case may be, registered under a Shelf Registration Statement, their directors, officers, employees or agents and each Person who controls such underwriter on substantially the same basis as that of the indemnification of the Purchasers and the selling Holders provided in this Section 7(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(p) hereof. (b) Each Holder of securities covered by a Registration Statement (including each Purchaser and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally, but not jointly, agrees to indemnify and hold harmless the Company and the Guarantors, each of their respective directors, each of their respective officers who signs such Registration Statement and each Person who controls the Company or the Guarantors within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company and the Guarantors to each such Holder, but only with reference to written information relating to such Holder furnished to the Company by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have. 19

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and is prejudiced thereby; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes (i) an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault or failure to act by or on behalf of any indemnified party. No indemnifying party shall be liable under subsections (a), (b) or (c) of this Section for any settlement of any claim or action effected without its consent, which consent will not be unreasonably withheld; provided, however, that such indemnifying party has notified in writing the indemnified party of its refusal to accept such settlement within 30 days of its receipt of a notice from the indemnified party outlining the terms of such settlement. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which such indemnified party may be subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on the other hand, from the Initial Placement and the Registration Statement which 20

resulted in such Losses; provided, however, that in no case shall any Purchaser of any Security or New Security be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to such Security, or in the case of a New Security, applicable to the Security that was exchangeable into such New Security, as set forth in the Final Memorandum, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such underwriter under the Registration Statement which resulted in such Losses, nor shall any subsequent Holder of any Security or New Security be responsible, in the aggregate, for any amount in excess of the net proceeds received by such Holder from the resale of such securities under the Registration Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company and the Guarantors shall be deemed to be equal to the sum of (x) the total net proceeds from the Initial Placement (before deducting expenses) as set forth in the Final Memorandum and (y) the total amount of additional interest which the Company and the Guarantors were not required to pay as a result of registering the securities covered by the Registration Statement which resulted in such Losses. Benefits received by the Purchasers shall be deemed to be equal to the total purchase discounts and commissions as set forth in the Final Memorandum, and benefits received by any other Holders shall be deemed to be equal to the value of receiving Securities or New Securities, as applicable, registered under the Act. Benefits received by any underwriter shall be deemed to be equal to the total underwriting discounts and commissions, as set forth on the cover page of the Prospectus forming a part of the Registration Statement which resulted in such Losses. Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission relates to information provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each Person who controls a Holder within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of such Holder shall have the same rights to contribution as such Holder, and each Person who controls the Company or the Guarantors within the meaning of either the Act or the Exchange Act, each officer of the Company and the Guarantors who shall have signed the Registration Statement and each director of the Company and the Guarantors shall have the same rights to contribution as the Company and the Guarantors, subject in each case to the applicable terms and conditions of this paragraph (d). (e) The provisions of this Section will remain in full force and effect, regardless of any investigation made by or on behalf of any Holder or the Company or the 21

Guarantors or any of the officers, directors or controlling Persons referred to in this Section hereof, and will survive the sale by a Holder of securities covered by a Registration Statement. 8. Underwritten Registrations. In connection with any Shelf Registration Statement required under this Agreement, the Company and the Guarantors may enter into one or more underwriting agreements, engagement letters, agency agreements, "best efforts" underwriting agreements or similar agreements, as appropriate, including customary provisions relating to indemnification and contribution, and take such other actions in connection therewith as the Majority Holders shall request in order to expedite or facilitate the disposition of such Securities. (a) If any of the Securities or New Securities, as the case may be, covered by any Shelf Registration Statement are to be sold in an underwritten offering, the Managing Underwriters shall be selected by the Majority Holders provided that such Managing Underwriters shall be reasonably satisfactory to the Company and the Guarantors. (b) No Person may participate in any underwritten offering pursuant to any Shelf Registration Statement, unless such Person (i) agrees to sell such Person's Securities or New Securities, as the case may be, on the basis reasonably provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements; and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 9. No Inconsistent Agreements. Neither the Company nor the Guarantors have, as of the date hereof, entered into, nor shall they, on or after the date hereof, enter into, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders herein or otherwise conflicts with the provisions hereof. 10. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the Company has obtained the written consent of the Majority Holders (or, after the consummation of any Registered Exchange Offer in accordance with Section 2 hereof, of New Securities); provided that, with respect to any matter that directly or indirectly affects the rights of any Purchaser hereunder, the Company shall obtain the written consent of each such Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to departure from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Securities or New Securities, as the case may be, are being sold pursuant to a Registration Statement and that does not directly or indirectly affect the rights of other Holders may be given by the Majority Holders, determined on the basis of Securities or New Securities, as the case may be, being sold rather than registered under such Registration Statement. 11. Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail, telex, telecopier or air courier guaranteeing overnight delivery: 22

(a) if to a Holder, at the most current address given by such holder to the Company in accordance with the provisions of this Section, which address initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture, with copies in like manner to Credit Suisse First Boston LLC. (b) if to you, initially at the respective addresses set forth in the Purchase Agreement; and (c) if to the Company or the Guarantors, initially at the address set forth in the Purchase Agreement with a copy to Company counsel at the following address: Palmer & Dodge LLP 11 Huntington Avenue Boston, MA 02199 Attn: Matthew J. Gardella Tel: (617) 239-0100 Facsimile: (617) 227-4420 All such notices and communications shall be deemed to have been duly given when received. The Purchasers, Company and the Guarantors by notice to the other parties may designate additional or different addresses for subsequent notices or communications. 12. Successors. This Agreement shall inure to the benefit of and be binding upon the successors and assigns of each of the parties, including, without the need for an express assignment or any consent by the Company or the Guarantors thereto, subsequent Holders of Securities and the New Securities. The Company and the Guarantors hereby agree to extend the benefits of this Agreement to any Holder of Securities and the New Securities, and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto. 13. Counterparts. This agreement may be in signed counterparts, each of which shall an original and all of which together shall constitute one and the same agreement. 14. Headings. The headings used herein are for convenience only and shall not affect the construction hereof. 15. Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed in the State of New York. 16. Severability. In the event that any one of more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or affected thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law. 23

17. Securities Held by the Company, Etc.

In such connection, the Company shall: (A) if requested by the Majority Holders, furnish (or, in the case of paragraphs (2) and (3), use its reasonable best efforts to cause to be furnished) to the Selling Holders, upon the effectiveness of the Registration Statement: (1) a certificate, dated such date, signed on behalf of the Company by (x) the President or any Vice President and (y) a principal financial or accounting officer of the Company, confirming, as of the date thereof, the matters set forth in Sections 6(b) and 6(e) of the Purchase Agreement and such other similar matters as such Person may reasonably request; (2) an opinion, dated the date of effectiveness of the Registration Statement, of counsel for the Company covering matters similar to those set forth in Schedules D and E of the Purchase Agreement and such other matters as the Selling Holders may reasonably request, and in any event including a statement to the effect that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants for the Company and have considered the matters required to be stated therein and the statements contained therein, although such counsel has not independently verified the accuracy, completeness or fairness of such statements; and that such counsel advises that, on the basis of the foregoing (relying as to materiality to the extent such counsel deems appropriate upon the statements of officers and other representatives of the Company) and without independent check or verification), no facts came to such counsel's attention that caused such counsel to believe that the applicable Registration Statement, at the time such Registration Statement or any post-effective amendment thereto became effective, contained an untrue statement of a material fact or omitted to state a 6

material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus contained in such Registration Statement as of its date contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Without limiting the foregoing, such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, notes and schedules and other financial data included in any Registration Statement contemplated by this Agreement or the related Prospectus; and (3) a customary comfort letter, dated the date of effectiveness of the Registration Statement, from the Company's independent accountants, in the customary form and covering matters of the type customarily covered in comfort letters to underwriters in connection with underwritten offerings, and affirming the matters set forth in the comfort letters delivered pursuant to Section 9(i) of the Purchase Agreement; provided the appropriate representation letters are provided to the accountants from the Holders under Statement on Auditing Standards No. 72.

(xii) prior to any public offering of Transfer Restricted Securities, cooperate with the Selling Holders, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the securities or Blue Sky laws of such jurisdictions as the Holders or underwriter(s), if any, may request and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the applicable Registration Statement; provided, however, that where Transfer Restricted Securities are offered other than through an underwritten offering, the Company agrees to cause its counsel to perform Blue Sky investigations and file registrations and qualifications required to be filed pursuant to this Section 5(a)(xiii), keep each such registration or qualification (or exemption therefrom) effective during the period that the applicable Registration Statement is required to remain effective under the terms of this Agreement and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the securities covered thereby; provided that the Company shall not be required to register or qualify as a foreign corporation where it is not now so qualified or to take any action that would subject it to the service of process in suits or to taxation, other 7

than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not now so subject; (xiii) in connection with any sale of Transfer Restricted Securities that will result in such securities no longer being Transfer Restricted Securities, cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and to register such Transfer Restricted Securities in such denominations and such names as the selling Holders may reasonably request at least two Business Days prior to such sale of Transfer Restricted Securities; (xiv) use its reasonable best efforts to cause the disposition of the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in clause (xii) above; (xv) provide a CUSIP number for all Transfer Restricted Securities not later than the effective date of a Registration Statement covering such Transfer Restricted Securities and provide the Warrant Agent with printed certificates for the Transfer Restricted Securities which are in a form eligible for deposit with The Depository Trust Company; (xvi) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders with regard to any applicable Registration Statement, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) covering a twelve-month period beginning after the effective date of the Registration Statement (as such term is defined in Rule 158(c) under the Act); and (xvii) provide promptly to the Holders, upon written request, each document filed with the Commission pursuant to the requirements of Section 13 or Section 15(d) of the Exchange Act. (b) Restrictions on Holders. Each Holder agrees by acquisition of a Transfer Restricted Security and the Initial Purchasers agrees that, upon receipt of the notice (without notice of the nature or details of the events) from the Company of the commencement of a Black Out Period (in each case, a "Black Out Notice"), such Person will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until such Person is advised in writing by the Company of the termination of the Black Out Period and such Holder receives copies of the supplemented or amended Prospectus contemplated by Section 5(a)(v) hereof, or until such Holder is advised in writing by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company each Person receiving a Black Out Notice hereby agrees that it will either (i) destroy any Prospectuses, other than permanent file copies, then in such Person's possession which have been replaced by the Company with more recently dated Prospectuses or (ii) deliver to the Company (at the Company's expense) all copies, other than permanent file copies, then in such Person's possession of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of the Black Out Notice. 6. LIQUIDATED DAMAGES 8

If the Registration Statement: (i) is not filed with the Commission on or prior to the date specified for such filing in Section 3(a) hereof; (ii) has not been declared effective by the Commission on or prior to the dated specified for such effectiveness in Section 3(a) hereof; or (iii) following the date such Registration Statement is declared effective by the Commission, shall cease to be effective without being restored to effectiveness by amendment or otherwise within 30 business days, other than as permitted by Section 3(c) hereof (each such event referred to in clauses (i) through (iii), a "Registration Default") to the extent permitted by applicable law, the Company shall pay as liquidated damages and not as a penalty to each Holder during the first 90-day period immediately following the occurrence, and during the continuance of such Registration Default, an amount equal to $0.01 per week per Warrant (or per such number of Warrant Shares then issuable upon exercise of or in respect of a Warrant) held by such Holder for each week or portion thereof that the Registration Default continues. To the extent permitted by applicable law, the amount of the liquidated damages will increase by an additional $0.01 per week per Warrant (or per such number of Warrant Shares then issuable upon exercise of or in respect of a Warrant) with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a maximum amount of liquidated damages of $0.05 per week per Warrant (or per such number of Warrant Shares then issuable upon exercise of or in respect of a Warrant). All accrued liquidated damages shall be paid to record Holders by the Company by wire transfer of immediately available funds, or by mailing a federal funds check, on February 1 and August 1 of any given year. All obligations of the Company set forth in the preceding paragraph that are outstanding with respect to any Transfer Restricted Security at the time such security has been effectively registered under the Act shall survive until such time as all such obligations with respect to such security have been satisfied in full. 7. REGISTRATION EXPENSES All expenses incident to the Company's performance of or compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses; (ii) all fees and expenses of compliance with federal securities and state Blue Sky or securities laws; (iii) all expenses of printing (including printing Prospectuses (whether for sales, market-making or otherwise), messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Company; (v) all application and filing fees in connection with listing the Warrant Shares on a national securities exchange or automated quotation system pursuant to the requirements hereof; and (vi) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit (which shall not be required except to the extent required by applicable law) and comfort letters required by or incident to such performance). The Company will, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company. 8. INDEMNIFICATION (a) The Company agrees to indemnify and hold harmless each Holder, its directors, officers and each Person, if any, who controls such Holder (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act), from and against any and all losses, claims, damages, liabilities, judgments, (including, without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action that could give rise to any such losses, claims, 9

damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement, preliminary prospectus or Prospectus (or any amendment or supplement thereto) provided by the Company to any Holder or any prospective purchaser of Transfer Restricted Securities, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by an untrue statement or omission or alleged untrue statement or omission that is based upon information relating to a Holder furnished in writing to the Company by such Holder. (b) Each Holder of Transfer Restricted Securities agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors and officers, and each person, if any, who controls (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) the Company, to the same extent as the foregoing indemnity from the Company set forth in Section 6(a) hereof, but only with reference to information relating to such Holder furnished in writing to the Company by such Holder expressly for use in any Registration Statement. In no event shall any Holder, its directors, officers or any Person who controls such Holder be liable or responsible for any amount in excess of the amount by which the total amount received by such Holder with respect to its sale of Transfer Restricted Securities pursuant to a Registration Statement exceeds (i) the amount paid by such Holder for such Transfer Restricted Securities and (ii) the amount of any damages that such Holder, its directors, officers or any Person who controls such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. This indemnity agreement shall be in addition to any liability which any such Holder may otherwise have. (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the "indemnified party"), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing, and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that, in the case of any action in respect of which indemnity may be sought pursuant to both Sections 8(a) and 8(b), a Holder shall not be required to assume the defense of such action pursuant to this Section 8(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Holder). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party, unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such reasonable fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by a majority of the Holders, in the case of the parties indemnified pursuant to Section 8(a), and by the Company, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action effected with its written consent. The Company shall not, without the prior written consent of the 10

indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the indemnified party. (d) To the extent that the indemnification provided for in this Section 8 is unavailable to an indemnified party in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Holders, on the other hand, from their sale of Transfer Restricted Securities or (ii) if the allocation provided by clause 8(d)(i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) hereof but also the relative fault of the Company, on the one hand, and of the Holder, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Company, on the one hand, and of the Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, on the one hand, or by the Holder, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a), any reasonable legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or defending any matter, including any action that could have given rise to such losses, claims, damages, liabilities or judgments. The Company and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 8, no Holder, its directors, its officers or any Person, if any, who controls such Holder shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total received by such Holder with respect to the sale of Transfer Restricted Securities pursuant to a Registration Statement exceeds (i) the amount paid by such Holder for such Transfer Restricted Securities and (ii) the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders' obligations to contribute pursuant to this Section 8(d) are several in proportion to the respective principal amount of Transfer Restricted Securities held by each Holder hereunder and not joint. 9. RULE 144 The Company agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding and during any period in which the Company is subject to Section 13 or 15(d) of the Exchange Act, to make all filings required thereby in a timely manner in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144. 11

10. MISCELLANEOUS (a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under this Agreement may result in material irreparable injury to the Initial Purchasers or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchasers or any Holder may obtain such relief as may be required to specifically enforce the Company's obligations under Section 3 hereof. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. (b) No Inconsistent Agreements. The Company will not, on or after the date of this Agreement, enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company's securities under any agreement in effect on the date hereof, except that the filing of the Registration Statement hereunder would require notice to be sent to holders under the Company's registration rights agreement dated February 25, 1999, as amended, and require the inclusion of such holders in a Registration Statement filed hereunder. (c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless (i) in the case of this Section 10(c)(i), the Company has obtained the written consent of Holders of all outstanding Transfer Restricted Securities, and (ii) in the case of all other provisions hereof, the Company has obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities (excluding Transfer Restricted Securities held by the Company or its Affiliates). (d) Third Party Beneficiary. The Holders shall be third party beneficiaries to the agreements granting rights to Holders made hereunder between the Company, on the one hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent they may deem such enforcement necessary or advisable to protect its rights or the rights of Holders hereunder.

All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier, or air courier guaranteeing overnight delivery: (i) if to a Holder, at the address set forth on the records of the Warrant Agent, with a copy to the Warrant Agent; and (ii) if to the Company: American Tower Corporation 116 Huntington Avenue, 11/th/ Floor Boston, MA 02116 Telecopier No.: (617) 375-7575 Attention: Chief Financial Officer and Treasurer Executive Vice President and General Counsel 12
