AMERICAN TOWER We are a wireless communications and broadcast infrastructure company operating in three business segments. o We operate a leading network of communications towers and are the largest independent operator of broadcast towers in North America. Giving effect as of May 26, 2000 to our pending transactions, we have approximately 10,400 multi-user sites in the United States, Mexico and Canada, including approximately 300 broadcast tower sites. o We provide comprehensive network development services for wireless service providers and broadcasters. We offer full turnkey network development solutions to our customers, consisting of radio frequency engineering, network design, site acquisition, zoning and other regulatory approvals, construction management, tower construction and antenna installation. o We operate a leading teleport business, which transmits Internet, voice, data and video communications worldwide. We have approximately 160 satellite antennas in various locations across the United States, with major facilities near New York, Washington, D.C., Dallas and San Francisco, as well as the Northeast, Southwest and Pacific Northwest, giving effect as of May 26, 2000 to our pending transactions. We estimate that our three business segments accounted for the following percentages of pro forma 1999 operating revenues: o Rental and management--53.0%, o Network development services--27.0%, and o Internet, voice, data and video transmission services--20.0%. RISK FACTORS You should consider carefully the following factors and other information in this prospectus before deciding to invest in our securities. If we cannot keep raising capital, our growth will be impeded. Without additional capital, we would need to curtail our acquisition and construction programs. We expect to use borrowed funds to satisfy most of our capital needs. However, we must continue to satisfy financial ratios and to comply with financial and other covenants in order to do so. If our revenues and cash flow do not meet expectations, we may lose our ability to borrow money. These same factors, as well as market conditions beyond our control, could make it difficult or impossible for us to sell securities as an alternative to borrowing. Meeting payments on our large debt could be a burden to us. Our high debt level makes us vulnerable to downturns in our operations. This high debt level requires us to use most of our cash flow to make interest and principal payments. If we do not generate sufficient cash flow through our operations to make interest and principal payments, we may be forced to sell debt or equity securities or sell some of our core assets. This could be harmful to our business and our securityholders. Market conditions or our own financial situation may require us to make these sales on unattractive terms. Demand for tower space may be beyond our control. Many of the factors affecting the demand for tower space, and therefore our cash flow, are beyond our control. Those factors include: o consumer demand for wireless services, o the financial condition of wireless service providers and their preference for owning or leasing antennae sites, o the growth rate of wireless communications or of a particular wireless segment, o the number of wireless service providers in a particular segment, nationally or locally, -1-

o governmental licensing of broadcast rights, o zoning, environmental and other government regulations, and o technological changes. Roaming and resale arrangements could also adversely affect demand. These arrangements enable a wireless service provider to serve customers outside its license area through agreements with other providers. Wireless providers might consider roaming and resale arrangements preferable to leasing antennae space. New tower construction, particularly build-to-suit projects, involves uncontrollable risks and increasing competition. Our increasing focus on major build-to-suit projects for wireless service providers entails several unique risks. First is our greater dependence on a limited number of customers. In addition, although we have the benefit of an anchor tenant in build-to-suit projects, we may not be able to find a sufficient number of additional tenants. In fact, one reason wireless service providers may prefer build-to-suit arrangements is to share or escape the costs of an undesirable site. A site may be undesirable because it has high construction costs or may be considered a poor location by other providers. Our expanded construction activities also involve other substantial risks. These risks include: o increasing our debt and the amount of payments on that debt, o uncontrollable risks that could delay or increase the cost of a project, o increasing competition for construction sites and experienced tower construction companies, resulting in significantly higher costs and failure to meet time schedules, o failure to meet time schedules that could result in our paying significant penalties to prospective tenants, particularly in build-to-suit situations, and o possible lack of sufficient experienced personnel to manage an expanded construction program. We cannot control the main factors that can prevent, delay or increase the cost of construction. These factors include: o zoning and local permitting requirements, o environmental group opposition, o availability of skilled construction personnel and construction equipment, o adverse weather conditions, and o federal regulations. Our acquisition strategy involves increasing acquisition costs, high debt levels and potential management and integration issues. Increased competition, which we believe will continue, has resulted in substantially higher acquisition costs, particularly for towers being sold by wireless service providers. These prices, in turn, result in high debt and debt service requirements. Equally important, the increased size of our acquisitions from wireless service providers could create problems we have not faced in the past. These include: o dependence on a limited number of customers, o lease and control provisions more favorable to the wireless service provider than those we give our tenants generally, o integration of major national networks into our operational systems, o demands on managerial personnel that could divert their attention from other aspects of our business, and o potential antitrust constraints, either in local markets or on a regional or national basis, that could impede future acquisitions or require selective divestitures at unfavorable prices. An additional risk is the acquisition of significant numbers of towers that may have limited marketing potential. For example, towers may not be marketable because of location. Covenants in our credit facilities could impede our growth strategy and restrict our ability to pay interest on or redeem our notes. Our growth strategy may be impaired by restrictive covenants in our credit facilities. The most significant of these covenants impose limits on our aggregate borrowings, including in the case of -2-

American Tower, the parent company, the type and amount of borrowings. We are also required to meet certain financial ratios and comply with all of the financial and other covenants in order to borrow funds. Certain types of acquisitions and investments in other companies are limited. Events beyond our control may affect our ability to meet these requirements. If these covenants restrict our ability to borrow funds, acquisitions and construction will be impeded. Our credit facilities also restrict the ability of our subsidiaries to pay dividends or make other distributions to us and prohibit those dividends and other distributions during periods of default. Since we are a holding company, with no independent operations, we are dependent on our subsidiaries for funds to pay interest and principal on our notes, including any debt securities we offer pursuant to this prospectus. In addition, our credit facilities require us to invest 100% of all debt and equity offerings, public or private, in our borrower subsidiaries. Our existing credit facilities prohibit us from redeeming or repurchasing any currently outstanding notes for cash. This will probably require us to elect to repurchase currently outstanding notes with Class A common stock on the repurchase dates and to obtain lender consent in order to repurchase currently outstanding notes upon any change in control. This same limitation could impact our ability to redeem or repurchase any securities we may offer pursuant to this prospectus. We are dependent on key personnel and would be hurt if they leave. The loss of our chief executive officer, Steven B. Dodge, and other executive officers has a greater likelihood of having a material adverse effect upon us than it would on most other companies of our size. Our growth strategy is highly dependent on the efforts of Mr. Dodge and our other executive officers. Our ability to raise capital is dependent in part on the reputation of Mr. Dodge. You should be aware that we have not entered into employment agreements with Mr. Dodge or most of our other executive officers. We may not be able to retain our executive officers, including those with employment agreements, or other key personnel or prevent them from competing with us if they did leave. Expanding operations into foreign countries could create certain operational and financial risks. Our recent expansion into Canada and Mexico, and other possible foreign operations in the future, could result in adverse financial consequences and operational problems not experienced in the United States. We have made a substantial loan to a Mexican company and are committed to construct a sizable number of towers in that country. We have also invested in a Canadian joint venture that intends to acquire and construct towers in that country. We may also, in the future, engage in comparable transactions in other countries. 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 that could impair management control and operations. New technologies could make our tower antenna leasing services less desirable to potential tenants. Mobile satellite systems and other new technologies could compete with land-based wireless communications systems, thereby reducing the demand for tower lease space and other services we provide. The Federal Communications Commission has granted license applications for several low-earth orbiting satellite systems that are intended to provide mobile voice or data services. In addition, the emergence of new technologies could reduce the need for tower-based transmission and reception and have an adverse affect on our operations. 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. The growth in delivery of video services by direct broadcast satellites could also adversely affect demand for our antenna space. Demand for teleport services is subject to technological, competitive and regulatory factors beyond our control. Demand for teleport services by its primary historical base of video customers has been diverted to fiber optic transmission services in some instances. Teleport transmission services for Internet-related entities, however, have increased. Revenues from these new technologies may not continue to grow and -3-

may decline if other forms of transmission, fiber optic or otherwise, are introduced. In addition, our teleport satellite operations are dependent upon maintaining valid FCC licensing. We could be harmed if perceived health risks from radio emissions are substantiated. If a connection between radio emissions and possible negative health effects, including cancer, were established, we would be materially and adversely affected. The results of several substantial studies by the scientific community in recent years have been inconclusive. We and the lessees of antennae sites on our towers are subject to government regulations relating to radio frequency emissions. We do not maintain any significant insurance with respect to these matters. Pro forma financial information is based on estimates and assumptions and may not be indicative of actual future results. Our actual future results could vary materially and adversely from those reflected in the pro forma financial information we have incorporated by reference in this prospectus. That information is based upon a number of assumptions we believe to be reasonable. However, our two most significant acquisitions to date, the AirTouch and AT&T transactions, do not involve the acquisition of businesses. The towers involved in those acquisitions were operated as part of the wireless service divisions of AirTouch and AT&T. Those companies did not maintain extensive separate financial records or prepare financial statements for the operation of those towers. We have, however, compiled certain revenue and expense data of those towers in the pro forma information. In the case of certain expenses, we have estimated amounts based on both the limited information by the carriers and our own experience with comparable towers. Neither our auditors, AirTouch's auditors nor AT&T's auditors have expressed any opinion or provided any form of assurance with respect to AirTouch's or AT&T's historical data presented in the unaudited pro forma financial information. We could have liability under environmental laws. Under various federal, state and local environmental laws, we, as an owner, lessee or operator of real estate, may be liable for the substantive costs of remediating soil and groundwater contaminated by hazardous wastes. Some of these laws impose responsibility and liability on us even if we did not cause the contamination or even know about it. Almost all of the towers we own and operate, other than roof top towers, are located on parcels of land, which could result in substantial environmental liability. Our liability often will continue even if we sell the property. The debt will effectively rank junior to secured debt under our credit facilities. Our payment of principal and interest on any debt we may issue will effectively rank junior to all existing and future debt under our credit facilities. This is so because the debt under our credit facilities is issued or guaranteed by our subsidiaries and secured by their assets. Any debt we issue will also effectively rank junior to all other existing and future debt of our subsidiaries. We have also guaranteed that debt and secured our guaranty with our assets, including the stock of our subsidiaries. As a result, in the event of our insolvency, liquidation or reorganization, or should any of that debt be accelerated because of a default, we must pay that debt in full before we can make any payment on any debt we may sell publicly. No trading market may exist for any offered securities other than Class A common stock. No trading market for any offered securities other than Class A common stock may exist and one may never develop. Accordingly, you may not be able to sell those securities or sell them at an acceptable price. If a market were to develop, those offered securities could trade at prices that may be higher or lower than your purchase price depending on many factors, including prevailing interest rates, our operating results, the market for similar securities, and, if those securities are convertible or exchangeable, the market price of the Class A common stock. We do not intend to list any offered securities other than Class A common stock on any securities exchange or to seek approval for quotation through any automated quotation system. One or more of the managing underwriters, if any, may decide to make a market in the those offered securities. They would not, however, be obligated to do so and may discontinue market making at any time. Therefore, any liquidity may disappear and those offered securities may not be readily marketable. -4-

Control by our principal stockholders could deter mergers where you could get more than current market price for your stock. Control by Mr. Dodge and others may have the effect of discouraging a merger or other takeover of our company in which holders of common stock may be paid a premium for their shares over then-current market prices. Mr. Dodge, together with a limited number of our directors, may be able to control or block the vote on mergers and other matters submitted to the common stockholders. Our common stock does not pay dividends. We have never paid a dividend on our common stock and do not expect to pay cash dividends in the foreseeable future. In addition, our credit facilities effectively restrict the payment of cash dividends or other distributions and the repurchase, redemption or other acquisition of equity securities. RATIO OF EARNINGS TO FIXED CHARGES For purposes of calculating this ratio, earnings consist of loss before income taxes and extraordinary losses and fixed charges. Fixed charges consist of capitalized interest, interest expense, amortization of debt discount and related issuance costs and the component of rental expense that management believes to be representative of the interest factor on that expense. For the year ended December 31, 1998, interest expense included redeemable preferred stock dividends of $3.1 million. For each of the periods listed below, our ratio of earnings to fixed charges was less than 1.0:1. We had a deficiency in earnings to fixed charges in each period as follows (amounts in thousands): Period Deficiency ------ ---------- Period from July 17, 1995 (incorp- oration) to December 31, 1995........ $ 184 Year ended December 31, 1996............ 434 Year ended December 31, 1997............ 2,507 Year ended December 31, 1998............ 43,844 Year ended December 31, 1999............ 52,520 Three months ended March 31, 2000....... 53,595 USE OF PROCEEDS We expect to use net proceeds from the sale of the offered securities primarily to finance construction and acquisitions. We also expect to use those proceeds to finance general working capital requirements, including repayment from time to time of borrowings under our credit facilities. Any borrowings so repaid may be available in the future to finance construction and acquisitions and other general corporate purposes. We intend to continue actively seeking construction and acquisition prospects, including acquisitions of companies outside of the United States engaged in businesses related to the tower communications business in which we are not presently engaged. DESCRIPTION OF CERTAIN INDEBTEDNESS Credit Facilities The description below summarizes the more important terms of our borrowing arrangements, as currently in effect, which we refer to as the credit facilities. We have previously filed copies of the loan agreement governing the credit facilities with the SEC. See "Where You Can Find More Information." You should refer to that agreement for the complete terms of the credit facilities. Capitalized words used in the description below have specialized meanings defined in that agreement. Several of our principal operating subsidiaries have borrowed and expect to continue to borrow under the credit facilities. We refer to those borrowers collectively as the borrower subsidiaries. The credit facilities provide for up to $2.0 billion of loans, the funding of which has been committed to by the lenders. The credit facilities also contemplate possible additional borrowings of up to $500.0 million, although the lenders are not committed to fund those borrowings. Borrowings under the credit facilities are limited by (a) the cash flow of the borrower subsidiaries and the Restricted Subsidiaries, (b) their construction costs of Developing Towers, and (c) the aggregate number of Developing Towers and AirTouch towers we acquire. The credit facility is made up of three separate types of loans: o a $650.0 million reducing revolving credit facility maturing on June 30, 2007, -5-

o an $850.0 million multiple-draw term loan maturing on June 30, 2007, and o a $500.0 million term loan maturing on December 31, 2007. We are required to reduce the revolving credit commitments and to amortize the term loans quarterly, commencing March 31, 2003, in increasing amounts designed to repay the loans by maturity. We are also required to repay the loans, and reduce the commitments, out of the proceeds of asset sales and sales of equity or debt securities, by us or our subsidiaries, and out of cash flow. We can repay the loans voluntarily at any time, without penalty. We may incur indebtedness under the credit facilities for acquisitions, construction and other capital expenditures, working capital and general corporate purposes. The credit facilities require compliance with financial coverage ratios that measure Annualized Operating Cash Flow against Total Debt, Interest Expense, Pro Forma Debt Service and Fixed Charges. The credit facilities contain other financial and operational covenants and other restrictions with which the borrower subsidiaries and the Restricted Subsidiaries must comply, whether or not there are any borrowings outstanding. These include restrictions on certain types of acquisitions, other than towers and communications sites, indebtedness, liens, capital expenditures, investments in Unrestricted Subsidiaries, and the ability of the borrower subsidiaries and the Restricted Subsidiaries to pay dividends or make other distributions. The credit facilities include two events of default that restrict American Tower, the parent company: o it cannot have any Indebtedness for Money Borrowed outstanding other than (a) the convertible notes issued in October 1999 and February 2000, and (b) other Indebtedness for Money Borrowed in an aggregate amount not to exceed $500.0 million and containing certain terms, and o it is required to invest the net cash proceeds of any issue of Capital Stock (other than pursuant to permitted acquisitions and up to $2.0 million under stock option plans) or Indebtedness as equity in the borrower subsidiaries. Our permitted Indebtedness for Money Borrowed must (a) be unsecured, (b) have no scheduled payments of principal prior to June 30, 2008, (c) have no required cash payments of interest and (d) have other terms and conditions reasonably satisfactory to the Majority Lenders. We and the Restricted Subsidiaries have guaranteed all of the loans. We have secured the loans by liens on substantially all assets of the borrower subsidiaries and the Restricted Subsidiaries and all outstanding capital stock and other debt and equity interests of our direct and indirect subsidiaries. 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. In February 2000, we issued 5.00% Convertible Notes due 2010 in an aggregate principal amount of $450.0 million. We will accrete each year as interest expense in our financial statements the difference between the issue price and the principal amount at maturity of the 2.25% notes. The 6.25% notes are convertible into shares of Class A common stock at a conversion price of $24.40 per share. The 2.25% notes are convertible into shares of Class A common stock at a conversion price of $24.00 per share. The 5.00% notes are convertible into shares of Class A common stock at a conversion price of $51.50 per share. The conversion prices are subject to adjustment in certain customary circumstances. We may not redeem the 6.25% notes prior to October 22, 2002. Thereafter, we may redeem those notes, at our option, in whole or in part at a redemption price initially of 103.125% of the principal amount. The redemption price declines ratably immediately after October 15 of each following year to 100% of the principal amount in 2005. We may not redeem the 2.25% notes prior to October 22, 2003. Thereafter, we may redeem those notes, at our option, in whole or in part at increasing redemption prices designed to reflect the accrued original issue discount. We may not redeem the 5.00% notes prior to February 20, 2003. Thereafter, we may redeem those notes, at our option, in whole or in part at a redemption price initially of 102.50% of the principal amount. The redemption price declines ratably immediately after February 15 of each following year to 100% of the principal amount in 2006. We are also required to pay accrued and unpaid interest in all redemptions of any series of notes. -6-

Holders may require us to repurchase all or any of their 6.25% 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% notes on October 22, 2003 at those notes' issue price plus accreted original issue discount, together with accrued and unpaid interest. Holders may require us to repurchase all or any of their 5.00% notes on February 20, 2007 at their principal amount, together with accrued and unpaid interest. We may, at our option, elect to pay the repurchase price of any series in cash or shares of Class A common stock, or any combination thereof. Our credit facilities restrict our ability to repurchase these notes for cash. The indentures under which these notes are outstanding do not contain any restrictions on the payment of dividends, the incurrence of debt or liens or the repurchase of our equity securities or any financial covenants. Neither series of notes is entitled to the benefit of any sinking fund. The 6.25% notes, the 2.25% notes and the 5.00% notes are junior to our credit facilities and rank equally with each other. DESCRIPTION OF DEBT SECURITIES The debt securities will be our unsecured direct obligations. They may be senior or subordinated indebtedness. The debt securities will be issued under one or more indentures between us and a trustee. Any indenture will be subject to, and governed by, the Trust Indenture Act of 1939, as amended. The statements made in this prospectus relating to any indenture and the debt securities to be issued under any indenture are summaries of certain anticipated provisions of the indentures, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all provisions of the indentures and the debt securities. General We have filed with the registration statement relating to the offered securities a form of indenture relating to our senior securities and a form of indenture relating to our senior subordinated securities and subordinated securities. Our senior debt securities will rank equally and ratably in right of payment with other indebtedness of ours that is not subordinated. If we issue subordinated debt securities, they will be subordinated in right of payment to the prior payment in full of senior indebtedness, as defined in the applicable prospectus supplement, and may rank equally and ratably with any other subordinated indebtedness. They may, however, also be subordinated in right of payment to senior subordinated securities. See "--Subordination." We may issue the debt securities without limit as to aggregate principal amount, in one or more series, in each case as established from time to time in or pursuant to authority granted by a resolution of our board of directors or as established in one or more supplemental indentures. We need not issue all debt securities of one series at the same time. Unless we otherwise provide, we may reopen a series, without the consent of the holders of such series, for issuances of additional securities of that series. We anticipate that any indenture will provide that we may, but need not, designate more than one trustee under an indenture, each with respect to one or more series of debt securities. Any trustee under any indenture may resign or be removed with respect to one or more series of debt securities, and a successor trustee may be appointed to act with respect to that series. The applicable prospectus supplement will describe the specific terms relating to the series of debt securities we will offer, including, where applicable, the following: o the title and series designation and whether they are senior securities, senior subordinated securities or subordinated securities, o the aggregate principal amount of the securities, o the percentage of the principal amount at which we will issue the debt securities and, if other than the principal amount of the debt securities, the portion of the principal amount of the debt securities payable upon declaration of acceleration of the maturity of the debt securities, o if convertible, the initial conversion price, the conversion period and any other terms governing such conversion, o the stated maturity date, o any fixed or variable interest rate or rates per annum, o the date from which interest may accrue and any interest payment dates, -7-

o any sinking fund requirements, o any provisions for redemption, including the redemption price and any remarketing arrangements, o whether the securities are denominated or payable in United States dollars or a foreign currency or units of two or more foreign currencies, o the events of default and covenants of such securities, to the extent different from or in addition to those described in this prospectus, o whether we will issue the debt securities in certificated and/or book-entry form, o whether the debt securities will be in registered or bearer form and, if in registered form, the denominations if other than in even multiples of $1,000 and, if in bearer form, the denominations and terms and conditions relating thereto, o whether we will issue any of the debt securities in permanent global form and, if so, the terms and conditions, if any, upon which interests in the global security may be exchanged, in whole or in part, for the individual debt securities represented by the global security, o the applicability, if any, of the defeasance and covenant defeasance provisions described in this prospectus or any prospectus supplement, o whether we will pay additional amounts on the securities in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities instead of making this payment, and o the subordination provisions, if any, relating to the debt securities. We may issue debt securities at less than the principal amount payable upon maturity (we refer to these securities as "original issue discount securities"). If material or applicable, we will describe in the applicable prospectus supplement special U.S. federal income tax, accounting and other considerations applicable to original issue discount securities. Except as described under "--Merger, Consolidation or Sale of Assets" or as may be set forth in any prospectus supplement, an indenture will not contain any other provisions that would limit our ability to incur indebtedness or that would afford holders of the debt securities protection in the event of a highly leveraged or similar transaction involving us or in the event of a change of control. You should review carefully the applicable prospectus supplement for information with respect to events of default and covenants applicable to the securities being offered. Denominations, Interest, Registration and Transfer Unless otherwise described in the applicable prospectus supplement, we will issue the debt securities of any series that are registered securities in denominations that are even multiples of $1,000, other than global securities, which may be of any denomination. Unless otherwise specified in the applicable prospectus supplement, we will pay the interest on and principal of and premium, if any, on any debt securities at the corporate trust office of the trustee. At our option, however, we may make payment of interest by check mailed to the address of the person entitled to the payment as it appears in the applicable register or by wire transfer of funds to that person at an account maintained within the United States. If we do not punctually pay or duly provide for interest on any interest payment date, the defaulted interest will be paid either: o to the person in whose name the debt security is registered at the close of business on a special record date to be fixed by the applicable trustee or o in any other lawful manner, all as more completely described in the applicable indenture. You may have your debt securities broken into more debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed. This is called an "exchange." You may exchange or transfer debt securities at the office of the trustee. The trustee acts as our agent for registering debt securities in the names of holders and transferring debt securities. We may change this appointment to another entity or perform it ourselves. The entity performing the role of maintaining the list of registered holders is called the "security registrar." It will also perform transfers. -8-

You will not be required to pay a service charge to transfer or exchange debt securities, but you may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The security registrar will make the transfer or exchange only if it is satisfied with your proof of ownership. Merger, Consolidation or Sale of Assets Under any indenture, we are generally permitted to consolidate or merge with another company. We are also permitted to sell substantially all of our assets to another company, or to buy substantially all of the assets of another company. However, we may not take any of these actions unless all the following conditions are met: o If we merge out of existence or sell our assets, the other company must be a corporation, partnership or other entity organized under the laws of a State or the District of Columbia or under federal law. The other company must agree to be legally responsible for the debt securities. o The merger, sale of assets or other transaction must not cause a default on the debt securities. In addition, we must not already be in default, unless the merger or other transaction would cure the default. A default for this purpose would include any event that would be an event of default if the requirements for giving us default notice or our default having to exist for a specific period of time were disregarded. Events of Default and Related Matters Events of Default. The term "event of default" means any of the following: o We do not pay the principal or any premium on a debt security on its due date. o We do not pay interest on a debt security within 30 days of its due date. o We do not deposit any sinking fund payment on its due date. o We remain in breach of any other term of the applicable indenture for 60 days after we receive a notice of default stating we are in breach. Either the trustee or holders of 25% of the principal amount of debt securities of the affected series may send the notice. o We file for bankruptcy or certain other events in bankruptcy, insolvency or reorganization occur. o Any other event of default described in the applicable prospectus supplement occurs. Remedies If an Event of Default Occurs. If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the debt securities of the affected series may declare the entire principal amount of all the debt securities of that series to be due and immediately payable. This is called a declaration of acceleration of maturity. If an event of default occurs because of certain events in bankruptcy, insolvency or reorganization, the principal amount of all the debt securities of that series will be automatically accelerated, without any action by the trustee or any holder. At any time after the trustee or the holders have accelerated any series of debt securities, but before a judgment or decree for payment of the money due has been obtained, the holders of at least a majority in principal amount of the debt securities of the affected series may, under certain circumstances, rescind and annul such acceleration. Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the applicable indenture at the request of any holders unless the holders offer the trustee reasonable protection from expenses and liability. This is known as an indemnity. If reasonable indemnity is provided, the holders of a majority in principal amount of the outstanding securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture, subject to certain limitations. Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the debt securities, the following must occur: o You must give the trustee written notice that an event of default has occurred and remains uncured. o The holders of at least 25% in principal amount of all outstanding securities of the relevant series must make a written request that the trustee take action because of the default, and must offer -9-

reasonable indemnity to the trustee against the cost and other liabilities of taking that action. o The trustee must have not taken action for 60 days after receipt of the above notice and offer of indemnity. However, you are entitled at any time to bring a lawsuit for the payment of money due on your security after its due date. We will furnish to the trustee every year a written statement of certain of our officers certifying that to their knowledge we are in compliance with the applicable indenture and the debt securities, or else specifying any default. Modification of an Indenture There are three types of changes we can make to the indentures and the debt securities: Changes Requiring Your Approval. First, there are changes we cannot make to your debt securities without your specific approval. Following is a list of those types of changes: o change the stated maturity of the principal or interest on a debt security, o reduce any amounts due on a debt security, o reduce the amount of principal payable upon acceleration of the maturity of a debt security following a default, o change the place or currency of payment on a debt security, o impair your right to sue for payment, o modify the subordination provisions, if any, in a manner that is adverse to you, o reduce the percentage of holders of debt securities whose consent is needed to modify or amend an indenture, o reduce the percentage of holders of debt securities whose consent is needed to waive compliance with certain provisions of an indenture or to waive certain defaults, and o modify any other aspect of the provisions dealing with modification and waiver of an indenture. Changes Requiring a Majority Vote. The second type of change to an indenture and the debt securities is the kind that requires a vote in favor by holders of debt securities owning a majority of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect holders of the debt securities. We require the same vote to obtain a waiver of a past default. However, we cannot obtain a waiver of a payment default or any other aspect of an indenture or the debt securities listed in the first category described under "--Changes Requiring Your Approval" unless we obtain your individual consent to the waiver. Changes Not Requiring Approval. The third type of change does not require any vote by holders of debt securities. This type is limited to clarifications and certain other changes that would not adversely affect holders of the debt securities. Further Details Concerning Voting. When taking a vote, we will use the following rules to decide how much principal amount to attribute to a debt security: o For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the debt securities were accelerated to that date because of a default. o For debt securities whose principal amount is not known, we will use a special rule for that security described in the applicable prospectus supplement. An example is if the principal amount is based on an index. o For debt securities denominated in one or more foreign currencies or currency units, we will use the U.S. dollar equivalent. Debt securities are not considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust for you money for their payment or redemption or if we or one of our affiliates own them. Debt securities are also not eligible to vote if they have been fully defeased as described immediately below under "--Discharge, Defeasance and Covenant Defeasance--Full Defeasance." We are generally entitled to set any day as a record date for the purpose of determining the holders of outstanding securities entitled to vote or -10-

take other action under an indenture. If we set a record date, only persons who are holders of outstanding securities of the applicable series on the record date may vote or take the action. Moreover, the applicable holders must vote or take the action within 180 days following the record date or another period that we may specify. We may shorten or lengthen this period from time to time. Discharge, Defeasance and Covenant Defeasance Discharge. We may discharge some obligations to holders of any series of debt securities that either have become due and payable or will become due and payable within one year, or scheduled for redemption within one year, by irrevocably depositing with the trustee, in trust, funds in the applicable currency in an amount sufficient to pay the debt securities, including any premium and interest. Full Defeasance. We can, under particular circumstances, effect a full defeasance of your series of debt securities. By this we mean we can legally release ourselves from any payment or other obligations on the debt securities if we put in place the following arrangements to repay you: o We must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. o The current federal tax law must be changed or an IRS ruling must be issued permitting the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves. Under current federal tax law, the deposit and our legal release from the debt securities would be treated as though we took back your debt securities and gave you your share of the cash and notes or bonds deposited in trust. In that event, you could recognize gain or loss on the debt securities you give back to us. o We must deliver to the trustee a legal opinion confirming the tax law change described above. If we did accomplish full defeasance, you would have to rely solely on the trust deposit for repayment on the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent. You would also be released from any subordination provisions. Covenant Defeasance. Under current federal tax law, we can make the same type of deposit described above and be released from some of the restrictive covenants in the debt securities. This is called "covenant defeasance." In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and securities set aside in trust to repay the securities and you would be released from any subordination provisions. In order to achieve covenant defeasance, we must do the following: o We must deposit in trust for your benefit and the benefit of all other direct holders of the debt securities a combination of money and U.S. government or U.S. government agency notes or bonds that will generate enough cash to make interest, principal and any other payments on the debt securities on their various due dates. o We must deliver to the trustee a legal opinion confirming that under current federal income tax law we may make the above deposit without causing you to be taxed on the debt securities any differently than if we did not make the deposit and just repaid the debt securities ourselves. If we accomplish covenant defeasance, the following provisions of an indenture and the debt securities would no longer apply: o Any covenants applicable to the series of debt securities and described in the applicable prospectus supplement. o Any subordination provisions. o Certain events of default relating to breach of covenants and acceleration of the maturity of other debt set forth in any prospectus supplement. If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit. If one of the remaining events of default occurs, for example, our bankruptcy, and the debt securities become immediately due and payable, there may be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall. -11-

Subordination We will set forth in the applicable prospectus supplement the terms and conditions, if any, upon which any series of senior subordinated securities or subordinated securities is subordinated to debt securities of another series or to other indebtedness of ours. The terms will include a description of: o the indebtedness ranking senior to the debt securities being offered, o the restrictions on payments to the holders of the debt securities being offered while a default with respect to the senior indebtedness is continuing, o the restrictions, if any, on payments to the holders of the debt securities being offered following an event of default, and o provisions requiring holders of the debt securities being offered to remit some payments to holders of senior indebtedness. Global Securities If so set forth in the applicable prospectus supplement, we may issue the debt securities of a series in whole or in part in the form of one or more global securities that will be deposited with a depositary identified in the prospectus supplement. We may issue global securities in either registered or bearer form and in either temporary or permanent form. The specific terms of the depositary arrangement with respect to any series of debt securities will be described in the prospectus supplement. DESCRIPTION OF CAPITAL STOCK The description below summarizes the more important terms of our capital stock. Because this section is a summary, it does not describe every aspect of the capital stock. This summary is subject to and qualified in its entirety by reference to the provisions of our Restated Certificate of Incorporation, as amended, including by any applicable Certificates of Designation. We refer to it as the restated certificate. We have incorporated by reference a copy of the restated certificate as an exhibit to the registration statement of which this prospectus is a part. This summary is subject to and qualified by reference to the description of the particular terms of your series of preferred stock described in the applicable prospectus supplement. General Our authorized capital stock consists of 20,000,000 shares of preferred stock, $.01 par value per share, 500,000,000 shares of Class A common stock, $.01 par value per share, 50,000,000 shares of Class B common stock, $.01 par value per share, and 10,000,000 shares of Class C common stock, $.01 par value per share. Preferred Stock General. Our board of directors will determine the designations, preferences, limitations and relative rights of the 20,000,000 authorized and unissued shares of preferred stock, including: o the distinctive designation of each series and the number of shares that will constitute the series, o the voting rights, if any, of shares of the series, o the dividend rate on the shares of the series, any restriction, limitation or condition upon the payment of the dividends, whether dividends will be cumulative, and the dates on which dividends are payable, o the prices at which, and the terms and conditions on which, the shares of the series may be redeemed, if the shares are redeemable, o the purchase or sinking fund provisions, if any, for the purchase or redemption of shares of the series, o any preferential amount payable upon shares of the series upon our liquidation or the distribution of our assets, o if the shares are convertible, the price or rates of conversion at which, and the terms and conditions on which, the shares of the series may be converted into other securities, and o whether the series can be exchanged, at our option, into debt securities, and the terms and conditions of any permitted exchange. The issuance of preferred stock, or the issuance of rights to purchase preferred stock, could discourage an unsolicited acquisition proposal. In addition, the rights of holders of common stock will be subject to, and may be adversely affected by, the rights of -12-

holders of any preferred stock that we may issue in the future. The following description of the preferred stock sets forth some general terms and provisions of the preferred stock to which a prospectus supplement may relate. The statements below describing the preferred stock are in all respects subject to and qualified in their entirety by reference to the applicable provisions of our restated certificate, including any applicable certificates of designation, and our by-laws. The prospectus supplement will describe the specific terms as to each issuance of preferred stock, including: o the number of shares of the preferred stock offered, o the offering price of the preferred stock, o the dividend rate, when dividends will be paid, or the method of determining the dividend rate if it is based on a formula or not otherwise fixed, o the date from which dividends on the preferred stock shall accumulate, o the provisions for any auctioning or remarketing, if any, of the preferred stock, o the provision, if any, for redemption or a sinking fund, o the liquidation preference per share, o any listing of the preferred stock on a securities exchange, o whether the preferred stock will be convertible and, if so, the security into which it is convertible and the terms and conditions of conversion, including the conversion price or the manner of determining it, o whether interests in the preferred stock will be represented by depositary shares as more fully described below under "Description of Depositary Shares," o a discussion of federal income tax considerations, o the relative ranking and preferences of the preferred stock as to dividend and liquidation rights, o any limitations on issuance of any preferred stock ranking senior to or on a parity with the series of preferred stock being offered as to dividend and liquidation rights, o any limitations on direct or beneficial ownership and restrictions on transfer, and o any other specific terms, preferences, rights, limitations or restrictions of the preferred stock. As described under "Description of Depositary Shares," we may, at our option, elect to offer depositary shares evidenced by depositary receipts. If we elect to do this, each depositary receipt will represent a fractional interest in a share of the particular series of the preferred stock issued and deposited with a depositary. The applicable prospectus supplement will specify that fractional interest. Rank. Unless our board of directors otherwise determines and we so specify in the applicable prospectus supplement, we expect that the preferred stock will, with respect to dividend rights and rights upon liquidation, rank senior to all common stock. Dividends. Holders of preferred stock of each series will be entitled to receive cash and/or stock dividends at the rates and on the dates shown in the applicable prospectus supplement. Even though the preferred stock may specify a fixed dividend, our board of directors must declare those dividends and they may be paid only out of assets of legally available for payment. Each dividend will be payable to holders of record as they appear on our stock transfer books on the record dates fixed by our board of directors. In the case of preferred stock represented by depositary receipts, the records of the depositary referred to under "Description of Depositary Shares" will determine the persons to whom dividends are payable. Dividends on any series of preferred stock (we refer to that series, for ease of reference, as the "Applicable Series") may be cumulative or noncumulative, as provided in the applicable prospectus supplement. Cumulative dividends will be cumulative from and after the date shown in the applicable prospectus supplement. If our board of directors fails to declare a dividend on any Applicable Series that is noncumulative, the holders -13-

will have no right to receive, and we will have no obligation to pay, a dividend in respect of the applicable dividend period, whether or not dividends on that series are declared payable in the future. If the Applicable Series is entitled to a cumulative dividend, we may not declare, or pay or set aside for payment, any full dividends on any other series of preferred stock ranking, as to dividends, on a parity with or junior to the Applicable Series, unless we declare, and either pay or set aside for payment, full cumulative dividends on the Applicable Series for all past dividend periods and the then current dividend period. If the Applicable Series does not have a cumulative dividend, we must declare, and pay or set aside for payment, full dividends for the then current dividend period only. When dividends are not paid, or set aside for payment, in full upon any Applicable Series and the shares of any other series ranking on a parity as to dividends with the Applicable Series, we must declare, and pay or set aside for payment, all dividends upon the Applicable Series and any other parity series proportionately, in accordance with accrued and unpaid dividends of the several series. For these purposes, accrued and unpaid dividends do not include unpaid dividend periods on noncumulative preferred stock. No interest will be payable in respect of any dividend payment that may be in arrears. Except as provided in the immediately preceding paragraph, unless we declare, and pay or set aside for payment, full cumulative dividends, including for the then current period, on any cumulative Applicable Series, we may not declare, or pay or set aside for payment, any dividends or other distributions upon common stock or any other capital stock ranking junior to or on a parity with the Applicable Series as to dividends or upon liquidation. The foregoing restriction does not apply to dividends or other distributions paid in common stock or other capital stock ranking junior to the Applicable Series as to dividends and upon liquidation. If the Applicable Series is noncumulative, we need only declare, and pay or set aside for payment, the dividend for the then current period, before declaring dividends or distributions on common stock or junior or parity securities. In addition, under the circumstances that we could not declare a dividend, we may not redeem, purchase or otherwise acquire for any consideration any common stock or other parity or junior capital stock, except upon conversion into or exchange for common stock or other junior capital stock. We may, however, make purchases and redemptions otherwise prohibited pursuant to certain redemptions or pro rata offers to purchase the outstanding shares of the Applicable Series and any other parity series of preferred stock. We will credit any dividend payment made on an Applicable Series first against the earliest accrued but unpaid dividend due with respect to the series. Redemption. We may have the right and/or may be required to redeem the preferred stock, as a whole or in part, in each case upon the terms, if any, and at the times and at the redemption prices shown in the applicable prospectus supplement. Liquidation Preference. The applicable prospectus supplement will show the liquidation preference of the Applicable Series. Upon any voluntary or involuntary liquidation, before any distribution may be made to the holders of common stock or any other capital stock ranking junior in the distribution of assets upon any liquidation to the Applicable Series, the holders of the Applicable Series will be entitled to receive, out of assets of ours legally available for distribution to stockholders, liquidating distributions in the amount of the liquidation preference, plus an amount equal to all dividends accrued and unpaid. In the case of a noncumulative Applicable Series, accrued and unpaid dividends include only the then current dividend period. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of preferred stock will have no right or claim to any of our remaining assets. If liquidating distributions shall have been made in full to all holders of preferred stock, our remaining assets will be distributed among the holders of any other capital stock ranking junior to the preferred stock upon liquidation, according to their rights and preferences and in each case according to their number of shares. If, upon any voluntary or involuntary liquidation, our available assets are insufficient to pay the amount of the liquidating distributions on all outstanding shares of an Applicable Series and the corresponding amounts payable on all shares of other capital stock ranking on a parity in the distribution of assets with the Applicable Series, then the holders of the Applicable Series and all other equally ranking capital stock shall share ratably in the distribution in proportion to the full liquidating distributions to which they would otherwise be entitled. For these purposes, our consolidation or merger with or into any other corporation or other entity, or the sale, lease or conveyance of all or substantially all of our property or business, will not be deemed to constitute our liquidation. -14-

Voting Rights. Holders of the preferred stock will not have any voting rights, except as shown below or as otherwise from time to time required by law or as indicated in the applicable prospectus supplement. Conversion Rights. We will show in the applicable prospectus supplement the terms and conditions, if any, upon which you may, or we may require you to, convert shares of any series of preferred stock into common stock or any other class or series of capital stock will be shown. The terms will include the number of shares of common stock or other securities into which the shares are convertible, the conversion price, or the manner of determining it, the conversion period, provisions as to whether conversion will be at the option of the holders of the series or at our option, the events requiring an adjustment of the conversion price, and provisions affecting conversion upon the redemption of shares of the series. Our Exchange Rights. We will show in the applicable prospectus supplement the terms and conditions, if any, upon which we can require you to exchange shares of any series of preferred stock for junior subordinated debt or other debt securities. If an exchange is required, you will receive junior subordinated debt or other debt securities with a principal amount equal to the liquidation preference of the applicable series of preferred stock. The other terms will include the terms and provisions of the junior subordinated debt or other debt securities which will not be materially less favorable to you than those of the series of preferred stock being exchanged. Common Stock Dividends. Holders of record of shares of common stock on the record date fixed by our board of directors are entitled to receive dividends as declared by our board of directors out of funds legally available for that purpose. No dividends may be declared or paid in cash or property on any share of any class of common stock, however, unless simultaneously the same dividend is declared or paid on each share of the other classes of common stock. Dividends in the form of shares of stock of any company, including our company or any of our subsidiaries, are excepted from that requirement. In that case, the shares may differ as to voting rights to the extent that voting rights now differ among the different classes of common stock. In the case of any dividend payable in shares of common stock, holders of each class of common stock are entitled to receive the same percentage dividend, payable in shares of that class, as the holders of each other class. Dividends and other distributions on common stock are also subject to the rights of holders of any series of preferred stock that may be outstanding from time to time and under our credit facilities. See "--Dividend Restrictions" below. Voting Rights. Except as otherwise required by law and in the election of directors, and subject to the rights of holders of any series of preferred stock that may be outstanding from time to time, holders of shares of Class A common stock and Class B common stock have the exclusive voting rights and will vote as a single class on all matters submitted to a vote of the stockholders. Each share of Class A common stock is entitled to one vote and each share of Class B common stock is entitled to ten votes. The holders of the Class A common stock, voting as a separate class, have the right to elect two independent directors. The Class C common stock is nonvoting, except as otherwise required by Delaware corporate law. Delaware corporate law requires the affirmative vote of the holders of a majority of the outstanding shares of any class or series of common stock to approve, among other things, a change in the designations, preferences and limitations of the shares of that class or series. The restated certificate, however, requires the affirmative vote of the holders of not less than 66 2/3% of the Class A common stock and Class B common stock, voting as a single class, to amend most of the provisions of the restated certificate, including those relating to the provisions of the various classes of common stock, indemnification of directors, exoneration of directors for certain acts and the super-majority provision. The restated certificate: o limits the aggregate voting power of Steven B. Dodge and his controlled entities to 49.99% of the aggregate voting power of all shares of capital stock entitled to vote generally for the election of directors, less the voting power represented by the shares of Class B common stock acquired by Thomas H. Stoner, a director, and purchasers affiliated with him in a January 1998 private offering and owned by them or certain affiliates, o prohibits future issuances of Class B common stock, except upon exercise of then outstanding options and pursuant to stock dividends or stock splits, -15-

o limits transfers of Class B common stock to permitted transferees, o provides for automatic conversion of the Class B common stock to Class A common stock if the aggregate voting power of Mr. Dodge, Mr. Stoner and their respective controlled entities falls below 21.3%, and o requires the holders of a majority of Class A common stock to approve amendments adversely affecting the Class A common stock. Conversion Provisions. Shares of Class B common stock and Class C common stock are convertible, at any time at the option of the holder, on a share for share basis into shares of Class A common stock. The present owner of Class C common stock can convert that stock only upon the occurrence of a conversion event or with the consent of our board of directors. Shares of Class B common stock automatically convert into shares of Class A common stock upon any sale, transfer, assignment or other disposition other than (a) to permitted transferees, or (b) pursuant to pledges but not to the pledgee upon foreclosure. Permitted transferees include certain family members and other holders of Class B common stock. Liquidation Rights. Upon our liquidation, dissolution or winding up, the holders of each class of common stock are entitled to share ratably in all assets available for distribution after payment in full of creditors and payment in full to any holders of the preferred stock then outstanding of any amount required to be paid to them. Other Provisions. The holders of common stock are not entitled to preemptive or subscription rights. The shares of common stock presently outstanding are validly issued, fully paid and nonassessable. In any merger, consolidation or business combination, the holders of each class of common stock must receive the identical consideration to that received by holders of each other class of common stock. However, if shares of capital stock or other securities of any other company are distributed, they may differ as to voting rights to the same extent that voting rights then differ among the different classes of our common stock. No class of common stock may be subdivided, consolidated, reclassified or otherwise changed unless, concurrently, the other classes of common stock are subdivided, consolidated, reclassified or otherwise changed in the same proportion and in the same manner. Dividend Restrictions. Our credit facilities prohibit our borrower subsidiaries from paying cash dividends or distributions, or from purchasing or otherwise acquiring their capital stock or other equity interests. However, beginning on April 15, 2004, if no default exists or would be created under the credit facilities, our borrower subsidiaries may pay cash dividends or make other distributions of up to 50% of excess cash flow, for the preceding calendar year. Delaware Business Combination Provisions. Under Delaware corporate law, certain business combinations, including the issuance of equity securities, between a Delaware corporation and any "interested stockholder" must be approved by the holders of at least 66 2/3% of the voting stock not owned by the interested stockholder if it occurs within three years of the date the person became an interested stockholders. The voting requirement does not apply, however, if, before the acquisition, the corporation's board of directors approved either the business combination or the transaction which resulted in the person becoming an interested stockholder. "Interested stockholder" means any person who owns, directly or indirectly, 15.0% or more of the voting power of the corporation's shares of capital stock. The provision does not apply to Mr. Dodge because our board of directors approved the transaction pursuant to which he became an interested stockholder. Listing of Class A Common Stock. Our Class A common stock is traded on the NYSE under the symbol "AMT." Transfer Agent and Registrar. The transfer agent and registrar for our common stock is Harris Trust and Savings Bank, 311 West Monroe Street, Chicago, Illinois 60606. Its telephone number is (312) 461-4600. DESCRIPTION OF DEPOSITARY SHARES General. The description shown below and in any applicable prospectus supplement of certain provisions of any deposit agreement and of the depositary shares and depositary receipts representing depositary shares does not purport to be complete and is subject to and qualified in its entirety by reference to the forms of deposit agreement and depositary receipts relating to each applicable series of preferred stock. The deposit agreement and the depositary receipts contain the full legal text of the matters -16-

described in this section. We will file a copy of those documents with the SEC at or before the time of the offering of the applicable series of preferred stock. This summary also is subject to and qualified by reference to the description of the particular terms of your series of depositary shares described in the applicable prospectus supplement. We may, at our option, elect to offer fractional interests in shares of preferred stock, rather than shares of preferred stock. If we exercise this option, we will appoint a depositary to issue depositary receipts representing those fractional interests. Preferred stock of each series represented by depositary shares will be deposited under a separate deposit agreement between us and the depositary. The prospectus supplement relating to a series of depositary shares will show the name and address of the depositary. Subject to the terms of the applicable deposit agreement, each owner of depositary shares will be entitled to all of the dividend, voting, conversion, redemption, liquidation and other rights and preferences of the preferred stock represented by those depositary shares. The depositary shares will be evidenced by depositary receipts issued pursuant to the applicable deposit agreement. Upon surrender of depositary receipts at the office of the depositary, and upon payment of the charges provided in and subject to the terms of the deposit agreement, a holder of depositary shares is entitled to receive the shares of preferred stock underlying the surrendered depositary receipts. Dividends and Other Distributions. A depositary will be required to distribute all cash dividends or other cash distributions received in respect of the applicable preferred stock to the record holders of depositary receipts evidencing the related depositary shares in proportion to the number of depositary receipts owned by the holders. Fractions will be rounded down to the nearest whole cent. If the distribution is other than in cash, a depositary will be required to distribute property received by it to the record holders of depositary receipts entitled thereto, unless the depositary determines that it is not feasible to make the distribution. In that case, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders. No distributions will be made on any depositary shares that represent preferred stock converted or exchanged. The deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights offered by us to holders of the preferred stock will be made available to holders of depositary shares. All distributions are subject to obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary. Withdrawal Of Preferred Stock. You may receive the number of whole shares of your series of preferred stock and any money or other property represented by those depositary receipts after surrendering the depositary receipts at the corporate trust office of the depositary. Partial shares of preferred stock will not be issued. If the depositary shares which you surrender exceed the number of depositary shares that represent the number of whole shares of preferred stock you wish to withdraw, then the depositary will deliver to you at the same time a new depositary receipt evidencing the excess number of depositary shares. Once you have withdrawn your preferred stock, you will not be entitled to re-deposit that preferred stock under the deposit agreement in order to receive depositary shares. We do not expect that there will be any public trading market for withdrawn shares of preferred stock. Redemption of Depositary Shares. If we redeem a series of the preferred stock underlying the depositary shares, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of the series held by the depositary. The depositary will mail notice of redemption not less than 30 and not more than 60 days before the date fixed for redemption to the record holders of the depositary receipts evidencing the depositary shares we are redeeming at their addresses appearing in the depositary's books. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to the series of the preferred stock. Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares relating to shares of preferred stock so redeemed. If we are redeeming less than all of the depositary shares, the depositary will select the depositary shares we are redeeming by lot or pro rata as the depositary may determine. After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed outstanding. All rights of the holders of the depositary shares and the related depositary receipts will cease at that time, except the right to receive the money or other property to which the holders of -17-

depositary shares were entitled upon redemption. Receipt of the money or other property is subject to surrender to the depositary of the depositary receipts evidencing the redeemed depositary shares. Voting of the Preferred Stock. Upon receipt of notice of any meeting at which the holders of the applicable preferred stock are entitled to vote, a depositary will be required to mail the information contained in the notice of meeting to the record holders of the applicable depositary receipts. Each record holder of depositary receipts on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock represented by the holder's depositary shares. The depositary will try, as practical, to vote the shares as you instruct. We will agree to take all reasonable action that the depositary deems necessary in order to enable it to do so. If you do not instruct the depositary how to vote your shares, the depositary will abstain from voting those shares. Liquidation Preference. Upon our liquidation, whether voluntary or involuntary, the holders of each depositary share will be entitled to the fraction of the liquidation preference accorded each share of preferred stock represented by the depositary share, as shown in the applicable prospectus supplement. Conversion or Exchange of Preferred Stock. The depositary shares will not themselves be convertible into or exchangeable for common stock, preferred stock or any of our other securities or property. Nevertheless, if so specified in the applicable prospectus supplement, the depositary receipts may be surrendered by holders to the applicable depositary with written instructions to it to instruct us to cause conversion of the preferred stock represented by the depositary shares. Similarly, if so specified in the applicable prospectus supplement, we may require you to surrender all of your depositary receipts to the applicable depositary upon our requiring the exchange of the preferred stock represented by the depositary shares into our debt securities. We will agree that, upon receipt of the instruction and any amounts payable in connection with the conversion or exchange, we will cause the conversion or exchange using the same procedures as those provided for delivery of preferred stock to effect the conversion or exchange. If you are converting only a part of the depositary shares, the depositary will issue you a new depositary receipt for any unconverted depositary shares. Taxation. As owner of depositary shares, you will be treated for U.S. federal income tax purposes as if you were an owner of the series of preferred stock represented by the depositary shares. Therefore, you will be required to take into account for U.S. federal income tax purposes income and deductions to which you would be entitled if you were a holder of the underlying series of preferred stock. In addition: o no gain or loss will be recognized for U.S. federal income tax purposes upon the withdrawal of preferred stock in exchange for depositary shares as provided in the deposit agreement, o the tax basis of each share of preferred stock to you as exchanging owner of depositary shares will, upon exchange, be the same as the aggregate tax basis of the depositary shares exchanged for the preferred stock, and o if you held the depositary shares as a capital asset at the time of the exchange for preferred stock, the holding period for shares of the preferred stock will include the period during which you owned the depositary shares. Amendment and Termination of a Deposit Agreement. We and the applicable depositary are permitted to amend the provisions of the depositary receipts and the deposit agreement. However, the holders of at least a majority of the applicable depositary shares then outstanding must approve any amendment that adds or increases fees or charges or prejudices an important right of holders. Every holder of an outstanding depositary receipt at the time any amendment becomes effective, by continuing to hold the receipt, will be bound by the applicable deposit agreement as amended. Any deposit agreement may be terminated by us upon not less than 30 days' prior written notice to the applicable depositary if a majority of each series of preferred stock affected by the termination consents to the termination. When that occurs, the depositary will be required to deliver or make available to each holder of depositary receipts, upon surrender of the depositary receipts held by the holder, the number of whole or fractional shares of preferred stock as are represented by the depositary shares evidenced by the depositary receipts, together with any other property held by the depositary with respect to the depositary receipts. In addition, a deposit agreement will automatically terminate if: -18-

o all depositary shares outstanding it shall have been redeemed, o there shall have been a final distribution in respect of the related preferred stock in connection with our liquidation and the distribution shall have been made to the holders of depositary receipts evidencing the depositary shares underlying the preferred stock, or o each of the shares of related preferred stock shall have been converted or exchanged into securities not represented by depositary shares. Charges of a Depositary. We will pay all transfer and other taxes and governmental charges arising solely from the existence of a deposit agreement. In addition, we will pay the fees and expenses of a depositary in connection with the initial deposit of the preferred stock and any redemption of preferred stock. However, holders of depositary receipts will pay any transfer or other governmental charges and the fees and expenses of a depositary for any duties the holders request to be performed that are outside of those expressly provided for in the applicable deposit agreement. Resignation and Removal of Depositary. A depositary may resign at any time by delivering to us notice of its election to do so. In addition, we may at any time remove a depositary. Any resignation or removal will take effect when we appoint a successor depositary and it accepts the appointment. We must appoint a successor depositary within 60 days after delivery of the notice of resignation or removal. A depositary must be a bank or trust company having its principal office in the United States that has a combined capital and surplus of at least $50 million. Miscellaneous. A depositary will be required to forward to holders of depositary receipts any reports and communications from us that are received by it with respect to the related preferred stock. Neither a depositary nor we will be liable if it is prevented from or delayed in performing its obligations under a deposit agreement by law or any circumstances beyond its control. Our obligations and those of the depositary under a deposit agreement will be limited to performing their duties in good faith and without gross negligence or willful misconduct. Neither we nor any depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or related preferred stock unless satisfactory indemnity is furnished. We and each depositary will be permitted to rely on written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, by holders of depositary receipts, or by other persons believed in good faith to be competent to give the information, and on documents believed in good faith to be genuine and signed by a proper party. If a depositary receives conflicting claims, requests or instructions from any holders of depositary receipts, on the one hand, and us, on the other hand, the depositary shall be entitled to act on the claims, requests or instructions received from us. DESCRIPTION OF WARRANTS We may issue, together with any other securities being offered or separately, warrants entitling the holder to purchase from or sell to us, or to receive from us the cash value of the right to purchase or sell, debt securities, preferred stock, depositary shares or common stock. We and a warrant agent will enter a warrant agreements pursuant to which the warrants will be issued. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. We will file a copy of the warrants and the warrant agreement with the SEC at or before the time of the offering of the applicable series of warrants. In the case of each series of warrants, the applicable prospectus supplement will describe the terms of the warrants being offered thereby, including the following, if applicable: o the offering price, o the number of warrants offered, o the securities underlying the warrants, o the exercise price, the procedures for exercise of the warrants and the circumstances, if any, that will deem the warrants to be automatically exercised, o the date on which the warrants will expire, o federal income tax consequences, o the rights, if any, we have to redeem the warrant, o the name of the warrant agent, and -19-

o the other terms of the warrants. Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in the applicable prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of the securities. The warrant agreements may be amended or supplemented without the consent of the holders of the warrants to which it applies to effect changes that are not inconsistent with the provisions of the warrants and that do not adversely affect the interests of the holders of the warrants. However, any amendment that materially and adversely alters the rights of the holders of warrants will not be effective unless the holders of at least a majority of the applicable warrants then outstanding approve the amendment. Every holder of an outstanding warrant at the time any amendment becomes effective, by continuing to hold the warrant, will be bound by the applicable warrant agreement as amended thereby. The prospectus supplement applicable to a particular series of warrants may provide that certain provisions of the warrants, including the securities for which they may be exercisable, the exercise price, and the expiration date may not be altered without the consent of the holder of each warrant.

PART II INFORMATION NOT REQUIRED IN THE PROSPECTUS Item 14. Other Expenses of Issuance and Distribution. Set forth below is an estimate (except in the case of the registration fee) of the amount of fees and expenses to be incurred in connection with the issuance and distribution of the Offered Securities registered hereby, other than underwriting discounts and commissions. Registration fee under Securities Act............... $ 264,000 Blue sky fees and expenses.......................... 10,000 Accounting fees and expenses........................ 400,000 Legal fees and expenses............................. 400,000 Printing and engraving.............................. 200,000 Rating agencies fees................................ 100,000 Miscellaneous fees and expenses..................... 150,000 ------------ Total: ......................................... $1,524,000 ============ Item 15. Indemnification of Directors and Officers. Section 145 of the Delaware General Corporation Laws ("DGCL") provides, in effect, that any person made a party to any action by reason of the fact that he is or was a director, officer, employee or agent of American Tower Corporation (the "Company") may and, in certain cases, must be indemnified by the Company against, in the case of a non-derivative action, judgments, fines, amounts paid in settlement and reasonable expenses (including attorney's fees), if in either type of action he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company and, in a non-derivative action, which involves a criminal proceeding, in which such person had no reasonable cause to believe his conduct was unlawful. This indemnification does not apply, in a derivative action, to matters as to which it is adjudged that the director, officer, employee or agent is liable to the Company, unless upon court order it is determined that, despite such adjudication of liability, but in view of all the circumstances of the case, he is fairly and reasonably entitled to indemnity for expenses. Article XII of the Company's By-Laws provides that the Company shall indemnify each person who is or was an officer or director of the Company to the fullest extent permitted by Section 145 of the DGCL. Article Sixth of the Company's restated certificate of incorporation states than no director of the Company shall be personally liable to the Company or its stockholders for monetary damages for breach of fiduciary duty as a director, except for (i) breach of the director's duty of loyalty to the Company or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law, (iii) liability under Section 174 of the DGCL relating to certain unlawful dividends and stock repurchases, or (iv) any transaction from which the director derived an improper personal benefit. Reference is made to the Underwriting Agreements (Exhibits 1.1 through 1.5 hereto) which may contain certain provisions for indemnification by the underwriters of the Company, directors, officers and controlling persons under certain circumstances.

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) under the Securities Act of 1933 if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in this registration statement; and (iii) To include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement; provided, however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions referred to in Item 15 of this registration statement, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. (d) The undersigned registrant hereby undertakes: (1) To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act. (2) That for purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of Prospectus filed as part of this Registration Statement in II-3

reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was effective. (3) That for the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be initial bona fide offering thereof.

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 whenever stockholders owning a majority of the capital stock issued, outstanding and entitled to -1-

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. -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. At each such meeting every stockholder entitled to vote shall be entitled to do so in person, or by proxy appointed by an instrument in writing or as otherwise permitted by law subscribed by such stockholder and bearing a date not more than three (3) years prior to the meeting in question, unless said instrument provides for a longer period during which it is to remain in force. 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. 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 -3-

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. 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 -4-

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 each other and participation in a meeting pursuant to the foregoing provisions shall constitute presence in person at the meeting. -5-

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. SECTION 7. Quorum and Adjournment. Except as otherwise provided by law, the Certificate of Incorporation or otherwise, a majority of the directors shall constitute a quorum for the transaction of business. If at any meeting of the Board there shall be less than a quorum present, a majority of those present may adjourn the meeting from time to time without notice other than announcement of the adjournment at the meeting, and at such adjourned meeting at which a quorum is present any business may be transacted which might have been transacted at the meeting as originally noticed. SECTION 8. Compensation. Directors shall receive compensation for their services, as such, and for service on any Committee of the Board of Directors, as fixed by resolution of the Board of Directors and for expenses of attendance at each regular or special meeting of the Board or any Committee thereof. Nothing in this Section shall be construed to preclude a director from serving the Corporation in any other capacity and receiving compensation therefor. SECTION 9. Action By Consent of Directors. Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting if all members of the Board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board or committee. Such consent shall be treated as a vote adopted at a meeting for all purposes. Such consents may be executed in one or more counterparts and not every Director or committee member need sign the same counterpart. ARTICLE V COMMITTEES OF DIRECTORS SECTION 1. Executive Committee. The Board of Directors may, by resolution passed by a majority of the whole Board, appoint an Executive Committee of one (1) or more members, to serve during the pleasure of the Board, to consist of such directors as the Board may from time to time designate. The Board of Directors shall designate the Chairman of the Executive Committee. (a) Procedure. The Executive Committee shall, by a vote of a majority of its members, fix its own times and places of meeting, determine the number of its members constituting a quorum for the transaction of business, and prescribe its own rules of procedure, no change in which shall be made save by a majority vote of its members. (b) Responsibilities. During the intervals between the meetings of the Board of Directors, except as otherwise provided by the Board of Directors in establishing such Committee or otherwise, the Executive Committee shall possess and may exercise all the powers of the Board in the management and direction of the business and affairs of the Corporation; provided, however, that the Executive Committee shall not, except to the extent the Certificate of Incorporation or the -6-

resolution providing for the issuance of shares of stock adopted by the Board of Directors as provided in Section 151(a) of the Delaware General Business Corporation Law, have the power: (i) to amend or authorize the amendment of the Certificate of Incorporation or these By-Laws; (ii) to authorize the issuance of stock in excess of one million (1,000,000) shares in any single transaction or group of related transactions; (iii) to authorize the payment of any dividend; (iv) to adopt an agreement of merger or consolidation pursuant to which the Corporation will merge or consolidate or to recommend to the stockholders the sale, lease or exchange of all or substantially all the property and business of the Corporation; (v) to recommend to the stockholders a dissolution, or a revocation of a dissolution, of the Corporation; or (vi) to adopt a certificate of ownership and merger pursuant to Section 253 of the Delaware Business Corporation Law; and further (c) Reports. The Executive Committee shall keep regular minutes of its proceedings, and all action by the Executive Committee shall be reported promptly to the Board of Directors. Such action shall be subject to review, amendment and repeal by the Board, provided that no rights of third parties shall be adversely affected by such review, amendment or repeal. (d) Appointment of Additional Members. In the absence or disqualification of any member of the Executive Committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not constituting a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member. SECTION 2. Audit Committee. The Board of Directors may, by resolution passed by a majority of the whole Board, appoint an Audit Committee of one (1) or more members who shall not be officers or employees of the Corporation to serve during the pleasure of the Board. The Board of Directors shall designate the Chairman of the Audit Committee. (a) Procedure. The Audit Committee, by a vote of a majority of its members, shall fix its own times and places of meeting, shall determine the number of its members constituting a quorum for the transaction of business, and shall prescribe its own rules of procedure, no change in which shall be made save by a majority vote of its members. -7-

(b) Responsibilities. The Audit Committee shall review the annual financial statements of the Corporation prior to their submission to the Board of Directors, shall consult with the Corporation's independent auditors, and may examine and consider such other matters in relation to the internal and external audit of the Corporation's accounts and in relation to the financial affairs of the Corporation and its accounts, including the selection and retention of independent auditors, as the Audit Committee may, in its discretion, determine to be desirable. (c) Reports. The Audit Committee shall keep regular minutes of its proceedings, and all action by the Audit Committee shall, from time to time, be reported to the Board of Directors as it shall direct.

Every certificate for shares of stock which are subject to any restriction on transfer pursuant to law, the Certificate of Incorporation, these By-Laws, or any agreement to which the Corporation is a party, shall have the restriction noted conspicuously on the certificate, and shall also set forth, on the face or back, either the full text of the restriction or a statement of the existence of such restriction and (except if such restriction is imposed by law) a statement that the Corporation will furnish a copy thereof to the holder of such certificate upon written request and without charge. 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 2. Transfer of Shares. The shares of the stock of the Corporation shall be transferred on the books of the Corporation by the holder thereof in person or by his or her attorney lawfully constituted, upon surrender for cancellation of certificates for the same number of shares, with an assignment and power of transfer endorsed thereon or attached thereto, duly executed, with such proof or guaranty of the authenticity of the signature as the Corporation or its agents may reasonably require. The Corporation shall be entitled to treat the holder of record of any share or shares of stock as the holder in fact thereof and accordingly shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person whether or not it shall have express or other notice thereof, save as expressly provided by law or by the Certificate of Incorporation. It shall be the duty of each stockholder to notify the Corporation of his or her post office address. SECTION 3. Closing of Transfer Books. The stock transfer books of the Corporation may, if deemed appropriate by the Board of Directors, be closed for such length of time not exceeding fifty (50) days as the Board may determine, preceding the date of any meeting of stockholders or the date for the payment of any dividend or the date for the allotment of rights or the date when any issuance, change, conversion or exchange of capital stock shall go into effect, during which time no transfer of stock on the books of the Corporation may be made. 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 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 -12-

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 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, -13-

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. SECTION 6. Uncertificated Shares. The Board of Directors of the Corporation may by resolution provide that one or more of any or all classes or series of the stock of the Corporation shall be uncertificated shares, subject to the provisions of Section 158 of the Delaware General Corporation Law.

The Board of Directors may, however, in its discretion, require any or all such instruments to be signed by any two or more of such officers, or may permit any or all of such instruments to be signed by such other officer or officers, agent or agents, as it shall be thereunto authorize from time to time.

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 -15-

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. SECTION 3. Expense Advance. Expenses (including attorneys' fees) incurred by an officer or director of the Corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the Corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the manner provided in Section 2 of this Article upon receipt of an undertaking by or on behalf of such officer or director to repay such amount, unless it shall ultimately be determined that such person is entitled to be indemnified by the Corporation as authorized in this Article. Such expenses (including attorneys' fees) incurred by other employees or agents of the Corporation may be so paid upon such terms and conditions, if any, as the Board of Directors deems appropriate. SECTION 4. Nonexclusivity. The indemnification and advancement of expenses provided by, or granted pursuant to, the other Sections of this Article shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in an official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a -16-

director, officer, partner, member, trustee, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. SECTION 5. Insurance. The Corporation shall have power to purchase and maintain insurance on behalf of any person who 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 any liability asserted against and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify such person against such liability under the provisions of this Article or Section 145 of the Delaware General Corporation Law. SECTION 6. "The Corporation". For the purposes of this Article, references to "the Corporation" shall include the resulting corporation and, to the extent that the Board of Directors of the resulting corporation so decides, all constituent corporations (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and employees or agents so that any person who is or was a director, officer, employee or agent of such a constituent corporation or is or was serving at the request of such constituent corporation as 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 shall stand in the same position under the provisions of this Article with respect to the resulting or surviving corporation if its separate existence had continued. SECTION 7. Other Indemnification. 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. SECTION 8. Other Definitions. For purposes of this Article, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the Corporation" shall include any service as a director, trustee, officer, employee or agent of the Corporation which imposes duties on, or involves services by, such director, trustee, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner he or she reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the Corporation" as referred to in this Article. SECTION 9. Continuation of Indemnification. The indemnification and advancement of expenses provided by, or granted pursuant to, this Article shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, trustee, partner, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. -17-

SECTION 10. Amendment or Repeal. Neither the amendment nor repeal of this Article nor the adoption of any provision of these By-Laws inconsistent with this Article shall reduce, eliminate or adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the effectiveness of such amendment, repeal or adoption. -18-

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. The ownership of Securities shall be proved by the Security Register. -13-

Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. With respect to any record date set pursuant to this Section, the Company may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Trustee in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the Company shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. -14-

Section 105 Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: ................., or (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company. Section 106 Notice to Holders; Waiver. Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. Section 107 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. -15-

Section 108 Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. Section 109 Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. Section 110 Separability Clause. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. Section 111 Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, the holders of Senior Debt and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. Section 112 Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York. Section 113 Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity. -16-

(h) the obligation, if any, of the Company to redeem or purchase any Securities of the series pursuant to any sinking fund or analogous provisions or at the option of the Holder thereof and the period or periods within which, the price or prices at which and the terms and conditions upon which any Securities of the series shall be redeemed or purchased, in whole or in part, pursuant to such obligation; (i) if other than denominations of $1,000 and any integral multiple thereof, the denominations in which any Securities of the series shall be issuable; (j) if the amount of principal of or any premium or interest on any Securities of the series may be determined with reference to an index or pursuant to a formula, the manner in which such amounts shall be determined; (k) if other than the currency of the United States of America, the currency, currencies or currency units in which the principal of or any premium or interest on any Securities of the series shall be payable and the manner of determining the equivalent thereof in the currency of the United States of America for any purpose, including for purposes of the definition of "Outstanding" in Section 101; (l) if the principal of or any premium or interest on any Securities of the series is to be payable, at the election of the Company or the Holder thereof, in one or more currencies or currency units other than that or those in which such Securities are stated to be payable, the currency, currencies or currency units in which the principal of or any premium or interest on such Securities as to which such election is made shall be payable, the periods within which and the terms and conditions upon which such election is to be made and the amount so payable (or the manner in which such amount shall be determined); (m) if other than the entire principal amount thereof, the portion of the principal amount of any Securities of the series which shall be payable upon declaration of acceleration of the Maturity thereof pursuant to Section 502; (n) if the principal amount payable at the Stated Maturity of any Securities of the series will not be determinable as of any one or more dates prior to the Stated Maturity, the amount which shall be deemed to be the principal amount of such Securities as of any such date for any purpose thereunder or hereunder, including the principal amount thereof which shall be due and payable upon any Maturity other than the Stated Maturity or which shall be deemed to be Outstanding as of any date prior to the Stated Maturity (or, in any such case, the manner in which such amount deemed to be the principal amount shall be determined); (o) if applicable, that the Securities of the series, in whole or any specified part, shall be defeasible pursuant to Section 1302 or Section 1303 or both such Sections and, if other than by a Board Resolution, the manner in which any election by the Company to defease such Securities shall be evidenced; -25-

(p) if applicable, that any Securities of the series shall be issuable in whole or in part in the form of one or more Global Securities and, in such case, the respective Depositaries for such Global Securities, the form of any legend or legends which shall be borne by any such Global Security in addition to or in lieu of that set forth in Section 204 and any circumstances in addition to or in lieu of those set forth in Clause (2) of the last paragraph of Section 305 in which any such Global Security may be exchanged in whole or in part for Securities registered, and any transfer of such Global Security in whole or in part may be registered, in the name or names of Persons other than the Depositary for such Global Security or a nominee thereof; (q) any addition to or change in the Events of Default which applies to any Securities of the series and any change in the right of the Trustee or the requisite Holders of such Securities to declare the principal amount thereof due and payable pursuant to Section 502; (r) any addition to or change in the covenants set forth in Article Ten which applies to Securities of the series; (s) if applicable, that the Securities of the series are convertible into or exchangeable for Common Stock or other securities of the Company, the period or periods within which, the price or prices at which and the terms and conditions upon which, and the limitations and restrictions, if any, upon which, any Securities of the series shall be convertible or exchangeable, in whole or in part, into Common Stock or other securities of the Company; and (t) any other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Section 901(5)). All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officers' Certificate referred to above or in any such indenture supplemental hereto. If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers' Certificate setting forth the terms of the series. The Securities shall be subordinated in right of payment to Senior Debt as provided in Article Fourteen. Section 302 Denominations. The Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the -26-

Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. Section 303 Execution, Authentication, Delivery and Dating. The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities. At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. If the form or terms of the Securities of the series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating, (a) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this Indenture; (b) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 301, that such terms have been established in conformity with the provisions of this Indenture; and (c) that such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles. If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. -27-

Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers' Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. Section 304 Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. -28-

Section 305 Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (a) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange any -29-

Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. The provisions of clauses (a), (b), (c) and (d) below shall apply only to Global Securities: (a) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. (b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (i) such Depositary (A) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (B) has ceased to be a clearing agency registered under the Exchange Act, (ii) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (iii) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301. (c) Subject to Clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct. (d) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. Section 306 Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (a) evidence to their satisfaction of the destruction, loss or theft of any Security and (b) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in -30-

lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. Section 307 Payment of Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below: (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the -31-

proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). (b) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. Section 308 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. Section 309 Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may -32-

deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. Section 310 Computation of Interest. Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. ARTICLE FOUR Satisfaction and Discharge Section 401 Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) either (i) all Securities theretofore authenticated and delivered (other than (A) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or (ii) all such Securities not theretofore delivered to the Trustee for cancellation (A) have become due and payable, or (B) will become due and payable at their Stated Maturity within one year, or (C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, -33-

and the Company, in the case of (A), (B) or (C) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose money in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive. Section 402 Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities 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 principal and any premium and interest for whose payment such money has been deposited with the Trustee. ARTICLE FIVE Remedies Section 501 Events of Default. "Event of Default", wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article Fourteen or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or -34-

(b) default in the payment of the principal of or any premium on any Security of that series at its Maturity; or (c) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series; or (d) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of series of Securities other than that series), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (e) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company or any Restricted Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company or any such Restricted Subsidiary a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any such Restricted Subsidiary under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any such Restricted Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or (f) the commencement by the Company or any Restricted Subsidiary of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any such Restricted Subsidiary to the entry of a decree or order for relief in respect of the Company or any such Restricted Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company or any such Restricted Subsidiary, or the filing by the Company or any such Restricted Subsidiary of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by the Company or any such Restricted Subsidiary to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any such Restricted Subsidiary or of any substantial part of the property of the Company or any such Restricted Subsidiary, or the making by the -35-

Company or any such Restricted Subsidiary of an assignment for the benefit of creditors, or the admission by the Company or any such Restricted Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any such Restricted Subsidiary in furtherance of any such action; or (g) any other Event of Default provided with respect to Securities of that series. Section 502 Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 501(6) or 501(7)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default specified in clause (e) or (f) of Section 501 with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (i) all overdue interest on all Securities of that series, (ii) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, (iii) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and -36-

(iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (b) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission shall affect any subsequent default or impair any right consequent thereon. The Trustee shall not be required to act upon an Event of Default unless it has actual knowledge of such Event of Default. Section 503 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if (a) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or (b) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, 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. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. Section 504 Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Section 511 Delay or Omission Not Waiver.

The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the Company. If at any time: (1) the Trustee shall fail to comply with Section 608 after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at least six months, or (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by the Company or by any such Holder, or (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.

In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (a) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (b) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (c) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. -46-

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. Section 612 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. Section 613 Preferential Collection of Claims Against Company. If and when the Trustee shall be or become a creditor of the Company (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Company (or any such other obligor).

The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, -47-

the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607.

Section 902 Supplemental Indentures With Consent of Holders. With the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of each series affected by such supplemental indenture, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security affected thereby, (a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security or any other Security which would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 502, or change any Place of Payment where, or the coin or currency in which, any Security or any premium or interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or modify the provisions of this Indenture with respect to the subordination of the Securities in a manner materially adverse to the Holders, or (b) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this Indenture, or (c) modify any of the provisions of this Section, Section 513 or Section 1009, except to increase any such percentage or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to "the Trustee" and concomitant changes in this Section and Section 1009, or the deletion of this proviso, in accordance with the requirements of Section 611 and clause (h) of Section 901. A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. -53-

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. Section 903 Execution of Supplemental Indentures. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. Section 904 Effect of Supplemental Indentures. Upon the execution of any supplemental indenture under this Article, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. Section 905 Conformity with Trust Indenture Act. Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act. Section 906 Reference in Securities to Supplemental Indentures. Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. ARTICLE TEN Covenants Section 1001 Payment of Principal, Premium and Interest.

Section 1002 Maintenance of Office or Agency. The Company will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. Section 1003 Money for Securities Payments to Be Held in Trust. If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. -55-

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, 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 a newspaper published in the English language, customarily published on each Business Day and of general circulation in ......................., 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 publication, any unclaimed balance of such money then remaining will be repaid to the Company. Section 1004 Statement by Officers as to Default. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers' Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. Section 1005 Existence. Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. -56-

Section 1006 Maintenance of Properties. The Company will cause all properties used or useful in the conduct of its business or the business of any Restricted Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company or any Restricted Subsidiary from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company or such Restricted Subsidiary, desirable in the conduct of its business or the business of any such Restricted Subsidiary and not disadvantageous in any material respect to the Holders. Section 1007 Payment of Taxes and Other Claims. The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any of its Restricted Subsidiaries, and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any of its Restricted Subsidiaries; provided, however, that the Company or such Restricted Subsidiary shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. Section 1008 Maintenance of Insurance. The Company shall, and shall cause its Restricted Subsidiaries to, keep at all times all of their properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties in accordance with good business practice. The Company shall, and shall cause its Restricted Subsidiaries to, use the proceeds from any such insurance policy to repair, replace or otherwise restore the property to which such proceeds relate. Section 1009 Waiver of Certain Covenants. Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to clause (r) of Section 301 or clause (b) or (g) of Section 901 for the benefit of the Holders of such series or in any of Sections 1005 to 1007, inclusive, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or -57-

generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. ARTICLE ELEVEN Redemption of Securities Section 1101 Applicability of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article. Section 1102 Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction. Section 1103 Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. -58-

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. Section 1104 Notice of Redemption. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. All notices of redemption shall state: (a) the Redemption Date, (b) the Redemption Price, (c) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, (d) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, (e) that on the Redemption Date, if such is the case, the right of the holders of each such Security to convert the Securities shall terminate; (f) the place or places where each such Security is to be surrendered for payment of the Redemption Price, and (g) that the redemption is for a sinking fund, if such is the case. -59-

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. Section 1105 Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. Section 1106 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. Section 1107 Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. -60-

ARTICLE TWELVE Sinking Funds Section 1201 Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as contemplated by Section 301 for such Securities. The minimum amount of any sinking fund payment provided for by the terms of any Securities is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an "optional sinking fund payment". If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities. Section 1202 Satisfaction of Sinking Fund Payments with Securities. The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. Section 1203 Redemption of Securities for Sinking Fund. Not less than 30 days prior to each sinking fund payment date for any Securities, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Not less than 15 days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. -61-

For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 1304 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, (b) the Company's obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (d) this Article.

(c) In the event of an election to have Section 1303 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur. (d) The Company shall have delivered to the Trustee an Officer's Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. (e) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in clause (e) or (f) of Section 501, at any time on or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day). (f) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). (g) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is bound. (h) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder. -64-

(i) At the time of such deposit, (i) no default in the payment of any principal of or premium or interest on any Senior Debt shall have occurred and be continuing, (ii) no event of default with respect to any Senior Debt shall have resulted in such Senior Debt becoming, and continuing to be, due and payable prior to the date on which it would otherwise have become due and payable (unless payment of such Senior Debt has been made or duly provided for), and (iii) no other event of default with respect to any Senior Debt shall have occurred and be continuing permitting (after notice or lapse of time or both) the holders of such Senior Debt (or a trustee on behalf of such holders) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable. (j) The Company shall have delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. Section 1305 Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are referred to collectively as the "Trustee") pursuant to Section 1304 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law. Money and U.S. Government Obligations so held in trust shall not be subject to the provisions of Article Fourteen. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities. Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. -65-

Section 1306 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 1302 or 1303 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1305 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. ARTICLE FOURTEEN Subordination of Securities Section 1401 Securities Subordinate to Senior Debt. The Company covenants and agrees, and each Holder of a Security, by his acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article (subject to the provisions of Article Four and Article Thirteen), the payment of the principal of (and premium, if any) and interest on each and all of the Securities are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Debt. Section 1402 Payment Over of Proceeds Upon Dissolution, Etc. In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company or to its creditors, as such, or to its assets, or (b) any liquidation, dissolution or other winding up of the Company, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets or liabilities of the Company, then and in any such event specified in (a), (b) or (c) above (each such event, if any, herein sometimes referred to as a "Proceeding") the holders of Senior Debt will be first entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Debt, or provision shall be made for such payment, in cash or Cash Equivalents or otherwise in a manner satisfactory to the holders of Senior Debt, before the Holders of the Securities are entitled to receive any payment or distribution of any kind or character, on account of principal of (or premium, if any) or interest on or other obligations in respect of the Securities or on account of any purchase or other acquisition of Securities by the Company or any Subsidiary of the Company (all such payments, distributions, purchases and acquisitions herein referred to, individually and collectively, as a "Securities -66-

Payment"), and to that end the holders of Senior Debt shall be entitled to receive, for application to the payment thereof, any Securities Payment which may be payable or deliverable in respect of the Securities in any such Proceeding. In the event that, notwithstanding the foregoing provisions of this Section, the Trustee receives payment or distribution of assets of the Company of any kind or character, before all the Senior Debt is paid in full in cash or Cash Equivalents, then and in such event such Securities Payment shall be paid over or delivered forthwith to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay the Senior Debt in full in cash or Cash Equivalents. For purposes of this Article only, the words "any payment or distribution of any kind or character, whether in cash, property or securities" shall not be deemed to include a payment or distribution of stock or securities of the Company provided for by a plan of reorganization or readjustment authorized by an order or decree of a court of competent jurisdiction in a reorganization proceeding under any applicable bankruptcy law or of any other corporation provided for by such plan of reorganization or readjustment which stock or securities are subordinated in right of payment to all then outstanding Senior Debt to at least the same extent as the Securities are so subordinated as provided in this Article; provided, however, that (a) if a new corporation results from such reorganization or readjustment, such corporation assumes any Senior Debt not paid in full in cash or Cash Equivalents in connection with such reorganization or readjustment and (b) the rights of the holders of such Senior Debt are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another Person or the liquidation or dissolution of the Company following the conveyance or transfer of all or substantially all of its properties and assets as an entirety to another Person upon the terms and conditions set forth in Article Eight shall not be deemed a Proceeding for the purposes of this Section if the Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer such properties and assets as an entirety, as the case may be, shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions set forth in Article Eight. Section 1403 No Payment When Senior Debt in Default. In the event that any Senior Payment Default (as defined below) shall have occurred and be continuing, then no Securities Payment shall be made unless and until such Senior Payment Default shall have been cured or waived or shall have ceased to exist or all amounts then due and payable in respect of Senior Debt shall have been paid in full, or provision shall have been made for such payment, in cash or Cash Equivalents or otherwise in a manner satisfactory to the holders of Senior Debt. "Senior Payment Default" means any default in the payment of principal of (or premium, if any) or interest on any Senior Debt when due, whether at the Maturity thereof or by declaration of acceleration, call for redemption or otherwise. -67-

In the event that any Senior Nonmonetary Default (as defined below) shall have occurred and be continuing, then, upon the receipt by the Company and the Trustee of written notice of such Senior Nonmonetary Default from the representatives of holders of the Designated Senior Debt to which such default relates, the Company may not make any payments (other than payments previously made pursuant to Article Fifteen) on account of the Securities or on account of the purchase or redemption or other acquisition of Securities for a period (the "blockage period") commencing on the date the Company and Trustee receive such written notice and ending on the earlier of (a) the 179th day after the date of such receipt of such written notice and (b) the date, if any, on which the Designated Senior Debt to which such default relates is discharged or such default is waived or otherwise cured. In any event, not more than one blockage period may be commenced during any period of 360 consecutive days and there shall be a period of at least 181 consecutive days in each period of 360 consecutive days when no blockage period is in effect. For all purposes of this paragraph, no Senior Nonmonetary Default that existed or was continuing on the date of commencement of any blockage period with respect to the Designated Senior Debt initiating such blockage period will be, or can be, made the basis for the commencement of a subsequent blockage period unless such default has been cured or waived for a period of not less than 180 consecutive days. "Senior Nonmonetary Default" means the occurrence or existence and continuance of any event of default, or of any event which, after notice or lapse of time (or both), would become an event of default, under the terms of any instrument pursuant to which any Designated Senior Debt is outstanding, permitting (after notice or lapse of time or both) one or more holders of such Senior Debt (or a trustee or agent on behalf of the holders thereof) to declare such Senior Debt due and payable prior to the date on which it would otherwise become due and payable, other than a Senior Payment Default. In the event and during the continuation of any default in the payment of principal of (or premium, if any) or interest on any Senior Debt beyond any applicable grace period with respect thereto, or in the event that any event of default with respect to any Senior Debt shall have occurred and be continuing permitting the holders of such Senior Debt (or a trustee on behalf of the holders thereof) to declare such Senior Debt, and shall have resulted in such Senior Debt becoming or being declared, due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been cured or waived or shall have ceased to exist, or in the event any judicial proceeding shall be pending with respect to any such default in payment or event of default, then no Securities Payment shall be made. In the event that, notwithstanding the foregoing, the Company shall make any Securities Payment to the Trustee or any Holder prohibited by the foregoing provisions of this Section, then and in such event, subject to Section 1404, such Securities Payment shall be paid over and delivered forthwith to the holders of the Senior Debt remaining unpaid, to the extent necessary to pay in full all the Senior Debt. The provisions of this Section shall not apply to any Securities Payment with respect to which Section 1402 would be applicable. -68-

Section 1404 Payment Permitted If No Default. Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the Company, at any time except during the pendency of any Proceeding referred to in Section 1402 or under the conditions described in Section 1403, from making Securities Payments, or (b) the application by the Trustee of any money deposited with it hereunder to Securities Payments or the retention of such Securities Payment by the Holders, if, at the time of such application by the Trustee, it did not have knowledge that such Securities Payment would have been prohibited by the provisions of this Article. Section 1405 Subrogation to Rights of Holders of Senior Debt. Subject to the payment in full of all amounts due or to become due on or in respect of Senior Debt, or the provision for such payment, in cash or Cash Equivalents or otherwise in a manner satisfactory to the holders of Senior Debt, the Holders of the Securities shall be subrogated (equally and ratably with the holders of all Indebtedness of the Company which by its express terms is subordinated to Indebtedness of the Company to substantially the same extent as the Securities are subordinated to the Senior Debt and is entitled to like rights of subrogation by reason of any payments or distributions made to holders of such Senior Debt) to the rights of the holders of such Senior Debt to receive payments and distributions of cash, property and securities applicable to the Senior Debt until the principal of (and premium, if any) and interest on the Securities shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of any cash, property or securities to which the Holders of the Securities or the Trustee would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Debt by Holders of the Securities or the Trustee, shall, as among the Company, its creditors other than holders of Senior Debt and the Holders of the Securities, be deemed to be a payment or distribution by the Company to or on account of the Senior Debt. Section 1406 Provisions Solely to Define Relative Rights. The provisions of this Article are and are intended solely for the purpose of defining the relative rights of the Holders on the one hand and the holders of Senior Debt on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Debt and the Holders of the Securities, the obligation of the Company, which is absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and interest on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the Holders of the Securities and creditors of the Company other than the holders of Senior Debt; or (c) prevent the Trustee or the Holder of any Security from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article of the holders of Senior Debt to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder. -69-

Section 1407 Trustee to Effectuate Subordination. Each Holder of a Security by his acceptance thereof authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article and appoints the Trustee his attorney-in-fact for any and all such purposes. Section 1408 No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Debt to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders of the Securities, without incurring responsibility to the Holders of the Securities and without impairing or releasing the subordination provided in this Article or the obligations hereunder of the Holders of the Securities to the holders of Senior Debt, do any one or more of the following: (a) change the manner, place or terms of payment or extend the time of payment of, or renew, increase or alter, Senior Debt, or otherwise amend or supplement in any manner Senior Debt or any instrument evidencing the same or any agreement under which Senior Debt is outstanding; (b) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing Senior Debt; (c) release any Person liable in any manner for the payment or collection of Senior Debt; and (d) exercise or refrain from exercising any rights against the Company and any other Person. Section 1409 Notice to Trustee. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Securities, unless and until the Trustee shall have received written notice thereof from the Company or a holder of Senior Debt or from any trustee therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 601, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice provided for in this Section at least three Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of (and premium, if any) or interest on any Security), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money was -70-

received and shall not be affected by any notice to the contrary which may be received by it within three Business Days prior to such date. Subject to the provisions of Section 601, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Debt (or a trustee therefor) to establish that such notice has been given by a holder of Senior Debt (or a trustee therefor). In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. Section 1410 Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company referred to in this Article, the Trustee, subject to the provisions of Section 601, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such Proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, for the purpose of ascertaining the Persons entitled to participate in such payment or 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. Section 1411 Trustee Not Fiduciary for Holders of Senior Debt. 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 it shall in good faith mistakenly pay over or distribute to Holders of Securities or to the Company or to any other Person cash, property or securities to which any holders of Senior Debt shall be entitled by virtue of this Article or otherwise. Section 1412 Rights of Trustee as Holder of Senior Debt; Preservation of Trustee's Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article with respect to any Senior Debt which may at any time be held by it, to the same extent as any other holder of Senior Debt, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. -71-

Nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 607. Section 1413 Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term "Trustee" as used in this Article shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article in addition to or in place of the Trustee; provided, however, that Section 1414 shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent. Section 1414 Defeasance of this Article Fourteen. The subordination of the Securities provided by this Article is expressly made subject to the provisions for defeasance or covenant defeasance in Article Thirteen hereof and, anything herein to the contrary notwithstanding, upon the effectiveness of any such defeasance or covenant defeasance, the Securities then outstanding shall thereupon cease to be subordinated pursuant to this Article Fourteen. ----------------------------- -72-

Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or -12-

affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. The ownership of Securities shall be proved by the Security Register. Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security. The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. With respect to any record date set pursuant to this Section, the Company may designate any day as the "Expiration Date" and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the Trustee in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section, the Company shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided in this paragraph. -13-

Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Section 105 Notices, Etc., to Trustee and Company. Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, (1) the Trustee by any Holder or by the Company shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, Attention: ................., or (2) the Company by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to it at the address of its principal office specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company. Section 106 Notice to Holders; Waiver. Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. Section 107 Conflict with Trust Indenture Act. If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any -14-

provision of the Trust Indenture Act which may be so modified or excluded, the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be. Section 108 Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. Section 109 Successors and Assigns. All covenants and agreements in this Indenture by the Company shall bind its successors and assigns, whether so expressed or not. Section 110 Separability Clause. In case any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. Section 111 Benefits of Indenture. Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder, the holders of Senior Debt and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture. Section 112 Governing Law. This Indenture and the Securities shall be governed by and construed in accordance with the law of the State of New York. Section 113 Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity. -15-

Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers' Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. Each Security shall be dated the date of its authentication. No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. Section 304 Temporary Securities. Pending the preparation of definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. If temporary Securities of any series are issued, the Company will cause definitive Securities of that series to be prepared without unreasonable delay. After the preparation of definitive Securities of such series, the temporary Securities of such series shall be exchangeable for definitive Securities of such series upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any series, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series and tenor. -27-

Section 305 Registration, Registration of Transfer and Exchange. The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed "Security Registrar" for the purpose of registering Securities and transfers of Securities as herein provided. Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of Payment for that series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange. Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing. No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 906 or 1107 not involving any transfer. If the Securities of any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (a) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 and ending at the close of business on the day of such mailing, or (b) to register the transfer of or exchange any -28-

Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. The provisions of clauses (a), (b), (c) and (d) below shall apply only to Global Securities: (a) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. (b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (i) such Depositary (A) has notified the Company that it is unwilling or unable to continue as Depositary for such Global Security or (B) has ceased to be a clearing agency registered under the Exchange Act, (ii) there shall have occurred and be continuing an Event of Default with respect to such Global Security or (iii) there shall exist such circumstances, if any, in addition to or in lieu of the foregoing as have been specified for this purpose as contemplated by Section 301. (c) Subject to Clause (2) above, any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security shall direct. (d) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof. Section 306 Mutilated, Destroyed, Lost and Stolen Securities. If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. If there shall be delivered to the Company and the Trustee (a) evidence to their satisfaction of the destruction, loss or theft of any Security and (b) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and the Trustee shall authenticate and deliver, in -29-

lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. Section 307 Payment of Interest; Interest Rights Preserved. Except as otherwise provided as contemplated by Section 301 with respect to any series of Securities, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest. Any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below: (a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the -30-

proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). (b) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. Section 308 Persons Deemed Owners. Prior to due presentment of a Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary. Section 309 Cancellation. All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever, and may -31-

deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of as directed by a Company Order. Section 310 Computation of Interest. Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months. ARTICLE FOUR Satisfaction and Discharge Section 401 Satisfaction and Discharge of Indenture. This Indenture shall upon Company Request cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of Securities herein expressly provided for), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when (a) either (i) all Securities theretofore authenticated and delivered (other than (A) Securities which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or (ii) all such Securities not theretofore delivered to the Trustee for cancellation (A) have become due and payable, or (B) will become due and payable at their Stated Maturity within one year, or (C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, -32-

and the Company, in the case of (A), (B) or (C) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose money in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Securities which have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and (c) the Company has delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 607, the obligations of the Trustee to any Authenticating Agent under Section 614 and, if money shall have been deposited with the Trustee pursuant to subclause (ii) of clause (a) of this Section, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive. Section 402 Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with the provisions of the Securities 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 principal and any premium and interest for whose payment such money has been deposited with the Trustee. ARTICLE FIVE Remedies Section 501 Events of Default. "Event of Default", wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be occasioned by the provisions of Article Fourteen or be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): (a) default in the payment of any interest upon any Security of that series when it becomes due and payable, and continuance of such default for a period of 30 days; or -33-

(b) default in the payment of the principal of or any premium on any Security of that series at its Maturity; or (c) default in the deposit of any sinking fund payment, when and as due by the terms of a Security of that series; or (d) default in the performance, or breach, of any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in whose performance or whose breach is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of series of Securities other than that series), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or (e) the entry by a court having jurisdiction in the premises of (i) a decree or order for relief in respect of the Company or any Restricted Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (ii) a decree or order adjudging the Company or any such Restricted Subsidiary a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or any such Restricted Subsidiary under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any such Restricted Subsidiary or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; or (f) the commencement by the Company or any Restricted Subsidiary of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by the Company or any such Restricted Subsidiary to the entry of a decree or order for relief in respect of the Company or any such Restricted Subsidiary in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against the Company or any such Restricted Subsidiary, or the filing by the Company or any such Restricted Subsidiary of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by the Company or any such Restricted Subsidiary to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of the Company or any such Restricted Subsidiary or of any substantial part of the property of the Company or any such Restricted Subsidiary, or the making by -34-

the Company or any such Restricted Subsidiary of an assignment for the benefit of creditors, or the admission by the Company or any such Restricted Subsidiary in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or any such Restricted Subsidiary in furtherance of any such action; or (g) any other Event of Default provided with respect to Securities of that series. Section 502 Acceleration of Maturity; Rescission and Annulment. If an Event of Default (other than an Event of Default specified in Section 501(6) or 501(7)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. If an Event of Default specified in clause (e) or (f) of Section 501 with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if (a) the Company has paid or deposited with the Trustee a sum sufficient to pay (i) all overdue interest on all Securities of that series, (ii) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, (iii) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and -35-

(iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and (b) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513. No such rescission shall affect any subsequent default or impair any right consequent thereon. The Trustee shall not be required to act upon an Event of Default unless it has actual knowledge of such Event of Default. Section 503 Collection of Indebtedness and Suits for Enforcement by Trustee. The Company covenants that if (a) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or (b) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof, the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, 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. If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. Section 504 Trustee May File Proofs of Claim. In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or -36-

other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official 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 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 607. No provision of this Indenture 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 Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors' or other similar committee. Section 505 Trustee May Enforce Claims Without Possession of Securities. All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. Section 506 Application of Money Collected. Any money collected by the Trustee pursuant to this Article shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: FIRST: To the payment of all amounts due the Trustee under Section 607; SECOND: To the extent provided in Article Fourteen, to the holders of Senior Debt of the Company in accordance with Article Fourteen; and THIRD: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively. -37-

Section 507 Limitation on Suits. No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; (b) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; (c) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; (d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and (e) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. Section 508 Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. Section 509 Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights -38-

and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. Section 510 Rights and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Section 511 Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. Section 512 Control by Holders. The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. Section 513 Waiver of Past Defaults. The Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except a default (a) in the payment of the principal of or any premium or interest on any Security of such series, or -39-

(b) in respect of a covenant or provision hereof which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 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. Section 514 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, suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. Section 515 Waiver of Usury, Stay or Extension Laws.

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 611. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 611, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company.

Section 611 Acceptance of Appointment by Successor. In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (a) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (b) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (c) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. -45-

Upon request of any such successor Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in the first or second preceding paragraph, as the case may be. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article. Section 612 Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. Section 613 Preferential Collection of Claims Against Company.

The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.

If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, -46-

the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company and shall give notice of such appointment in the manner provided in Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607.

Whenever the Company shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company (or any other obligor upon the Securities of that series) in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. -54-

The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, 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 a newspaper published in the English language, customarily published on each Business Day and of general circulation in ......................., 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 publication, any unclaimed balance of such money then remaining will be repaid to the Company. Section 1004 Statement by Officers as to Default. The Company will deliver to the Trustee, within 120 days after the end of each fiscal year of the Company ending after the date hereof, an Officers' Certificate, stating whether or not to the best knowledge of the signers thereof the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice provided hereunder) and, if the Company shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. Section 1005 Existence. Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company shall not be required to preserve any such right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. -55-

Section 1006 Maintenance of Properties. The Company will cause all properties used or useful in the conduct of its business or the business of any Restricted Subsidiary to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company or any Restricted Subsidiary from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company or such Restricted Subsidiary, desirable in the conduct of its business or the business of any such Restricted Subsidiary and not disadvantageous in any material respect to the Holders. Section 1007 Payment of Taxes and Other Claims. The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any of its Restricted Subsidiaries, and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any of its Restricted Subsidiaries; provided, however, that the Company or such Restricted Subsidiary shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings. Section 1008 Maintenance of Insurance. The Company shall, and shall cause its Restricted Subsidiaries to, keep at all times all of their properties which are of an insurable nature insured against loss or damage with insurers believed by the Company to be responsible to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties in accordance with good business practice. The Company shall, and shall cause its Restricted Subsidiaries to, use the proceeds from any such insurance policy to repair, replace or otherwise restore the property to which such proceeds relate. Section 1009 Waiver of Certain Covenants. Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any covenant provided pursuant to clause (r) of Section 301 or clause (b) or (g) of Section 901 for the benefit of the Holders of such series or in any of Sections 1005 to 1007, inclusive, if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or -56-

generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. ARTICLE ELEVEN Redemption of Securities Section 1101 Applicability of Article. Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for such Securities) in accordance with this Article. Section 1102 Election to Redeem; Notice to Trustee. The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with such restriction. Section 1103 Selection by Trustee of Securities to Be Redeemed. If less than all the Securities of any series are to be redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series and specified tenor not previously called for redemption in accordance with the preceding sentence. -57-

The Trustee shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed. Section 1104 Notice of Redemption. Notice of redemption shall be given by first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. All notices of redemption shall state: (a) the Redemption Date, (b) the Redemption Price, (c) if less than all the Outstanding Securities of any series consisting of more than a single Security are to be redeemed, the identification (and, in the case of partial redemption of any such Securities, the principal amounts) of the particular Securities to be redeemed and, if less than all the Outstanding Securities of any series consisting of a single Security are to be redeemed, the principal amount of the particular Security to be redeemed, (d) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date, (e) that on the Redemption Date, if such is the case, the right of the holders of each such Security to convert the Securities shall terminate; (f) the place or places where each such Security is to be surrendered for payment of the Redemption Price, and (g) that the redemption is for a sinking fund, if such is the case. -58-

Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, at the Company's request, by the Trustee in the name and at the expense of the Company and shall be irrevocable. Section 1105 Deposit of Redemption Price. Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities which are to be redeemed on that date. Section 1106 Securities Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 307. If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. Section 1107 Securities Redeemed in Part. Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. -59-

ARTICLE TWELVE Sinking Funds Section 1201 Applicability of Article. The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as contemplated by Section 301 for such Securities. The minimum amount of any sinking fund payment provided for by the terms of any Securities is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of such Securities is herein referred to as an "optional sinking fund payment". If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities as provided for by the terms of such Securities. Section 1202 Satisfaction of Sinking Fund Payments with Securities. The Company (1) may deliver Outstanding Securities of a series (other than any previously called for redemption) and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to any Securities of such series required to be made pursuant to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. Section 1203 Redemption of Securities for Sinking Fund. Not less than 30 days prior to each sinking fund payment date for any Securities, the Company will deliver to the Trustee an Officers' Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Securities pursuant to Section 1202 and will also deliver to the Trustee any Securities to be so delivered. Not less than 15 days prior to each such sinking fund payment date, the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. -60-

ARTICLE THIRTEEN Defeasance and Covenant Defeasance Section 1301 Company's Option to Effect Defeasance or Covenant Defeasance. The Company may elect, at its option at any time, to have Section 1302 or Section 1303 applied to any Securities or any series of Securities, as the case may be, designated pursuant to Section 301 as being defeasible pursuant to such Section 1302 or 1303, in accordance with any applicable requirements provided pursuant to Section 301 and upon compliance with the conditions set forth below in this Article. Any such election shall be evidenced by a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. Section 1302 Defeasance and Discharge. Upon the Company's exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations, and the provisions of Article Fourteen shall cease to be effective, with respect to such Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called "Defeasance"). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 1304 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such Securities when payments are due, (b) the Company's obligations with respect to such Securities under Sections 304, 305, 306, 1002 and 1003, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (d) this Article. Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any Securities notwithstanding the prior exercise of its option (if any) to have Section 1303 applied to such Securities. Section 1303 Covenant Defeasance. Upon the Company's exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, (a) the Company shall be released from its obligations under clause (c) of Section 801, Sections 1006 through 1008, inclusive, and any covenants provided pursuant to clause (r) of Section 301 or clause (b) or (g) of Section 901 for the benefit of the Holders of such Securities, and (b) the occurrence of any event specified in clause (d) of Section 501 (with respect to any of clause (c) of Section 801, Sections 1006 through 1008, inclusive, and any such covenants provided pursuant to clause (r) of Section 301 or clause (b) or (g) of Section 901 shall be deemed not to be or result in an Event of Default, and (c) the provisions of Article Fourteen shall cease to be effective, in each case with respect to such -61-

Securities as provided in this Section on and after the date the conditions set forth in Section 1304 are satisfied (hereinafter called "Covenant Defeasance"). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of clause (d) of Section 501) or Article Fourteen, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of this Indenture and such Securities shall be unaffected thereby. Section 1304 Conditions to Defeasance or Covenant Defeasance. The following shall be the conditions to the application of Section 1302 or Section 1303 to any Securities or any series of Securities, as the case may be: (a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 609 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (i) money in an amount, or (ii) U.S. Government Obligations which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination thereof, in each case sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee) to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, "U.S. Government Obligation" means (x) any security which is (i) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S. Government Obligation which is specified in Clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt. -62-

(b) In the event of an election to have Section 1302 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (i) or (ii) to the effect that, and based thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit, Defeasance and discharge were not to occur. (c) In the event of an election to have Section 1303 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were not to occur. (d) The Company shall have delivered to the Trustee an Officer's Certificate to the effect that neither such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. (e) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities or any other Securities shall have occurred and be continuing at the time of such deposit or, with regard to any such event specified in clause (e) or (f) of Section 501, at any time on or prior to the 90th day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 90th day). (f) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). (g) Such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company is a party or by which it is bound. (h) Such Defeasance or Covenant Defeasance shall not result in the trust arising from such deposit constituting an investment company within the meaning of the Investment Company Act unless such trust shall be registered under such Act or exempt from registration thereunder. -63-

(i) At the time of such deposit, (i) no default in the payment of any principal of or premium or interest on any Senior Debt shall have occurred and be continuing, (ii) no event of default with respect to any Senior Debt shall have resulted in such Senior Debt becoming, and continuing to be, due and payable prior to the date on which it would otherwise have become due and payable (unless payment of such Senior Debt has been made or duly provided for), and (iii) no other event of default with respect to any Senior Debt shall have occurred and be continuing permitting (after notice or lapse of time or both) the holders of such Senior Debt (or a trustee on behalf of such holders) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable. (j) The Company shall have delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. Section 1305 Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1306, the Trustee and any such other trustee are referred to collectively as the "Trustee") pursuant to Section 1304 in respect of any Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Securities, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in trust need not be segregated from other funds except to the extent required by law. Money and U.S. Government Obligations so held in trust shall not be subject to the provisions of Article Fourteen. The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1304 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of Outstanding Securities. Anything in this Article to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1304 with respect to any Securities which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Securities. -64-

Section 1306 Reinstatement. If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released pursuant to Section 1302 or 1303 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in trust pursuant to Section 1305 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. This instrument may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. In proving the existence of this Indenture it shall not be necessary to produce more than one copy.

common stock, $.01 par value per share, of the Company (the "Common Shares"), or
(v) warrants to purchase Debt Securities, Preferred Shares, Depositary Shares or
Common Shares (the "Warrants" and, together with the Debt Securities,  Preferred
Shares, Depositary Shares, and Common Shares, the "Registered Securities"),  for
offering by the Company from time to time, as set forth in the final  prospectus
that  forms  a  part  of the  Registration  Statement,  as  defined  below  (the
"Prospectus"),  and as to be set forth in one or more final  supplements  to the
Prospectus (each, a "Prospectus Supplement"), the following opinion is furnished
to the Company to be filed with the  Securities  and  Exchange  Commission  (the
"Commission") as Exhibit 5 to the Company's  Registration Statement on Form S-3,
under the Securities Act of 1933, as amended (the "Securities Act"), to be filed
on or about the date hereof.  As used in this  opinion,  the term  "Registration
Statement" means,  unless otherwise  stated,  such  Registration  Statement,  as
amended when  declared  effective by the  Commission  (including  any  necessary
post-effective amendments thereto); the term "Convertible Registered Securities"
means  Registered  Securities  which are convertible  into,  exchangeable for or
exercisable for other Registered Securities, and the term "Underlying Registered
Securities" means any Registered  Securities which are issuable upon conversion,
exchange or exercise of Convertible Registered Securities.

         In  connection  with this  opinion,  we have examined and relied upon a
copy of the  Registration  Statement to be filed with the Commission on or about
the date hereof.  We have also  examined and relied upon  originals or copies of
such records, agreements and instruments of the Company,  certificates of public
officials  and of officers of the Company and such other

American Tower Corporation May 26, 2000 Page 2 documents and records, and such matters of law, as we have deemed necessary as a basis for the opinions hereinafter expressed. In making such examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies, which facts we have not independently verified. We have necessarily assumed in connection with the opinions expressed below that the terms and conditions of the Registered Securities and any related indentures, agreements and instruments, except to the extent described in the Registration Statement and the form of preliminary prospectus contained therein, as originally filed, will be, and that any related proceedings of the Company conducted after the date hereof will be conducted, (i) in accordance with all applicable laws and the Company's Amended and Restated Certificate of Incorporation (the "Restated Certificate") and By-Laws, as amended, and (ii) not in conflict with any contractual or other restrictions which are binding on the Company, and that, without limiting the generality of the foregoing, any agreements or instruments that are hereafter required to be filed as an exhibit to the Registration Statement will be properly filed by an amendment thereto or by the filing of a Form 8-K by the Company under the Securities Exchange Act of 1934, as amended, and properly incorporated by reference in the Registration Statement, as permitted by the Securities Act and the rules and regulations of the Commission thereunder. We have also necessarily assumed in connection with such opinions with respect to any Common Shares or Preferred Shares or any Convertible Registered Securities as to which Common Shares or Preferred Shares are the related Underlying Registered Securities that, at the time of the issuance thereof, the Company will have a sufficient number of shares of authorized Common Shares or Preferred Shares, as the case may be, under the Restated Certificate that will be unissued and not otherwise reserved for issuance. To the extent that the obligations of the Company under each Indenture or any Warrant Agreement or Depositary Agreement (each as defined below) may be dependent upon such matters, we have assumed for purposes of this opinion that each Trustee, Warrant Agent and Depositary (each as defined below) are duly organized, validly existing and in good standing under the laws of their respective jurisdictions of organization, and are duly qualified to engage in the activities contemplated by, and have the requisite organizational and legal power and authority to perform their respective obligations under, each Indenture, Warrant Agreement and Depositary Agreement to which they are parties, that each Trustee, Warrant Agent and Depositary will be in compliance, generally with respect to acting as a trustee or agent under each applicable Indenture, Warrant Agreement and Depositary Agreement, with all applicable laws and regulations, and that each Indenture and any Warrant Agreement and Depositary Agreement will be the valid and binding agreements of each party thereto (other than, in the case of an indenture in the form filed as Exhibit 4.1 or 4.2 to the Registration Statement when appropriately completed, the Company), enforceable against such parties in accordance with their respective terms. We express no opinion herein as to the laws of any jurisdiction other than the laws of The Commonwealth of Massachusetts, the Delaware General Corporation Law and the federal laws

American Tower Corporation May 26, 2000 Page 3 of the United States of America, and we express no opinion as to state securities or blue sky laws. The opinions set forth below are also subject to the following additional qualifications: (a) The obligations, rights and remedies of parties may be limited by (i) bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws affecting the enforcement generally of the rights and remedies of creditors or the obligations of debtors, (ii) general principles of equity (regardless of whether considered in a proceeding at law or in equity), including, without limitation, the discretion of any court of competent jurisdiction in granting specific performance or injunctive or other equitable relief, and (iii) an implied duty on the part of the party seeking to enforce rights or remedies to take action and make determinations on a reasonable basis and in good faith to the extent required by applicable law. (b) We express no opinion as to the enforceability of prospective waivers of rights to notice or a hearing, or other rights granted by constitution or statute, powers of attorney, provisions purporting to relieve parties of the consequences of their own or their agent's negligence or misconduct, provisions granting indemnity or rights of contribution (which may be limited or prohibited by federal or state securities laws or public policy), or provisions purporting to establish evidentiary standards. (c) The enforceability of any security, obligation or agreement may be limited by general principles of contract law which include (i) the unenforceability of provisions to the effect that provisions therein may only be amended or waived in writing to the extent that an oral agreement modifying such provisions has been entered into or a course of conduct between the parties indicates otherwise, (ii) the general rule that, where less than all of an agreement is enforceable, the balance is enforceable only when the unenforceable portion is not an essential part of the agreed exchange, (iii) the exercise of judicial discretion regarding the determination of damages and entitlement to attorneys' fees and other costs, and (iv) the possible right of the a party which has materially failed to render or offer performance required by a contract to cure that failure, unless permitting a cure would unreasonably hinder the aggrieved party from making substitute arrangements for performance or it was important in the circumstance to the aggrieved party that performance occur by the date stated in such contract. (d) We express no opinion as to (i) whether a state or a federal court would give effect to the choice of law provided for in any security, obligation or agreement, (ii) the provisions of any agreement which purport to confer subject matter jurisdiction on any court, to consent to the jurisdiction of any court or to waive venue or inconvenient forum with respect to any court, (iii) any provisions of any security, obligation or agreement which purport to provide for a method of service of process which is inconsistent with applicable law or rules of the relevant court, (iv) any provision which purports to bind any party to agree to conclude an agreement at a future date, or (v) any provisions for the payment of any amount (other than stated interest rates or dividends) to the extent that a court may find that such payment constitutes a penalty. Based on and subject to the foregoing, we are of the opinion that, as of the date hereof:
