AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--Unaudited 1. Basis of Presentation and Accounting Policies The accompanying condensed consolidated financial statements have been prepared by American Tower Corporation (the Company) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). The financial information included herein is unaudited; however, the Company believes such information and the disclosures are adequate to make the information presented not misleading and reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair presentation of financial position and results of operations for such periods. Results of interim periods may not be indicative of results for the full year. These condensed consolidated financial statements and related notes should be read in conjunction with the Company's 2001 Annual Report on Form 10-K. Use of Estimates--The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the accompanying condensed consolidated financial statements. Loss Per Common Share--Basic and diluted loss per common share has been computed by dividing the Company's net loss by the weighted average number of common shares outstanding during the period. For the three months ended March 31, 2002 and 2001, potential common shares, including options, warrants and shares issuable upon conversion of the Company's convertible notes have been excluded from the computation of diluted loss per common share, as the effect is anti-dilutive. Potential common shares excluded from the calculation of loss per share were approximately 46.7 million and 52.4 million for the three months ended March 31, 2002 and 2001, respectively. Recent Accounting Pronouncements--On January 1, 2002, the Company adopted the provisions of Statement of Financial Accounting Standard (SFAS) No. 142 "Goodwill and Other Intangible Assets.'' SFAS No. 142 supersedes APB Opinion No. 17, "Intangible Assets," and requires that goodwill and intangible assets with indefinite lives no longer be amortized, but reviewed for impairment at least annually. Intangible assets that are deemed to have a definite life will continue to be amortized over their useful lives. The adoption of this statement reduced the Company's amortization expense and net loss by approximately $24.0 million or $0.12 per share for the three months ended March 31, 2002 and is expected to reduce annual amortization expense by approximately $96.0 million. Prior to the adoption of SFAS No. 142, the Company had approximately $1.1 billion of net goodwill that was amortized on a straight-line basis over a fifteen-year period. Had the Company accounted for goodwill and acquired workforce intangibles in accordance with SFAS No. 142 in 2001, net loss and loss per share for the three months ended March 31, 2002 and 2001 would have been as follows (in thousands): 2002 2001 -------- -------- Reported net loss before extraordinary loss........................ $(70,706) $(71,507) Add back: Goodwill amortization and acquired workforce amortization 22,530 -------- -------- Adjusted net loss before extraordinary loss........................

AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--Unaudited--(Continued) The Company is in the process of assessing the transitional impairment test and the related valuation of goodwill under SFAS No. 142 for the Company as a whole. However, upon completion of the transitional impairment test, the Company believes it will record a non-cash impairment charge in its statement of operations related to goodwill within its satellite and fiber network access services (SFNA) segment and its Services segment. Although the amount of the charges has not been determined, net goodwill related to the SFNA segment and the Services segment as of March 31, 2002 was approximately $188.0 million and $400.3 million, respectively. These charges will be reflected as a cumulative effect of a change in accounting principle in the Company's 2002 statement of operations. The changes in the net carrying amounts of goodwill by segment for the three months ended March 31, 2002 are as follows (in thousands): RM Services SFNA Total -------- -------- -------- ---------- Balance as of January 1, 2002................................. $574,777 $394,264 $185,433 $1,154,474 Goodwill acquired............................................. 1,763 1,763 Reclassification of acquired workforce intangibles to goodwill 6,081 2,607 8,688 -------- -------- -------- ---------- Balance as of March 31, 2002.................................. $576,540 $400,345 $188,040 $1,164,925 ======== ======== ======== ========== Summarized information about the Company's acquired intangible assets subject to amortization is as follows (in thousands): As of March 31, 2002 As of December 31, 2001 -------------------- ----------------------- Amortized intangible assets: Acquired customer base and network location intangibles $1,434,659 $1,425,183 Deferred financing costs............................... 94,724 104,957 Acquired licenses and other intangibles................ 65,327 65,131 Acquired workforce..................................... 13,056 ---------- ---------- Less accumulated amortization.......................... (281,121) (254,890) ---------- ---------- Amortized intangible assets, net........................ $1,313,589 $1,353,437 ========== ========== The Company amortizes its intangible assets over periods ranging from two to fifteen years. Amortization of intangible assets for the three months ended March 31, 2002 was approximately $29.8 million. The Company expects to record estimated amortization expense of $112.2 million on its intangible assets for the twelve months ended December 31, 2002 and estimated amortization expense of $108.4 million, $102.3 million, $100.6 million, $99.4 million and $97.1 million for the years ended December 31, 2003, 2004, 2005, 2006 and 2007, respectively. In August 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This statement supercedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The statement retains the previously existing accounting requirements related to the recognition and measurement of the impairment of long-lived assets to be held and used, while expanding the measurement requirements of long-lived assets to be disposed of by sale to include discontinued operations. It also expands the previously existing reporting requirements for discontinued operations to include a component of an entity that either has been disposed of or is classified as held for sale. The Company implemented SFAS No. 144 on January 1, 2002. The adoption of this statement did not have a material impact on the Company's consolidated financial position or results of operations. In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." This statement establishes accounting standards for the recognition and measurement of liabilities associated with the retirement of tangible long-lived assets and the related asset retirement costs. The requirements of SFAS No. 143 are effective for the Company as of January 1, 2003. The Company is currently evaluating the impact, if any, that this statement may have on its consolidated financial position or results of operations. 5

AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--Unaudited--(Continued) Reclassifications--Certain reclassifications have been made to the 2001 condensed consolidated financial statements and related notes to conform to the 2002 presentation. 2. Income Taxes The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year. Cumulative adjustments to the Company's estimate are recorded in the interim period in which a change in the estimated annual effective rate is determined. 3. Gain on Sale of Assets The Company sold 265 towers in the three months ended March 31, 2002 for proceeds of approximately $17.6 million and recognized a net gain on the sale of these assets of approximately $3.7 million. 4. Inventories Inventories are stated at the lower of cost or market, with cost being determined on the first-in, first-out (FIFO) basis. The components of inventories are as follows (in thousands): March 31, December 31, 2002 2001 --------- ------------ Raw materials................ $32,437 $37,387 Finished goods............... 15,172 11,300 Work in process.............. 1,193 645 ------- ------- Total..................... $48,802 $49,332 ======= ======= 5. Derivative Financial Instruments On January 1, 2001, the Company adopted the provisions of SFAS No. 133 "Accounting for Derivative Instruments and Hedging Activities." This statement established accounting and reporting standards for derivative instruments. Specifically, it requires that an entity recognize all derivatives as either assets or liabilities on the balance sheet at fair value. The accounting for changes in the fair market value of a derivative (that is unrealized gains or losses) is recorded as a component of an entity's net income or other comprehensive income, depending upon designation (as defined in the statement). The cumulative effect of adopting this statement resulted in a charge to other comprehensive loss of $7.9 million, net of tax, for the quarter ended March 31, 2001. The Company is exposed to interest rate risk relating to variable interest rates on its credit facilities. As part of its overall strategy to manage the level of exposure to the risk of interest rate fluctuations, the Company uses interest rate swaps, caps and collars, which qualify and are designated as cash flow hedges. In 2001, the Company also used swaptions to manage interest rate risk, which were not designated as cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative instrument is initially reported as a component of other comprehensive loss and subsequently reclassified into the statement of operations when the hedged transaction affects operations. The ineffective portion of the gain or loss on the derivative instrument is immediately recognized in the statement of operations. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in the statement of operations in the period of change. During the three months ended March 31, 2002, the Company recorded an unrealized loss of approximately $1.4 million (net of a tax provision of approximately $0.7 million) in other comprehensive loss for the change in fair value of cash flow hedges and reclassified $5.5 million (net of a tax benefit of $2.9 million) into results of 6

AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--Unaudited--(Continued) operations. During the three months ended March 31, 2001, the Company recorded an unrealized loss in other comprehensive loss, excluding the charge for the cumulative effect of adopting this statement, of approximately $8.0 million (net of a tax benefit of $4.3 million) and reclassified $0.1 million into results of operations. Hedge ineffectiveness resulted in a gain of approximately $0.5 million for the three months ended March 31, 2002 and 2001 which is recorded in "loss on investments and other expense" in the accompanying statements of operations. The Company records the changes in fair value of its derivative instruments that are not accounted for as hedges in "loss on investments and other expense." At March 31, 2002 and December 31, 2001, the fair value of the Company's derivative instruments represented a liability of approximately $20.9 million and $35.2 million, respectively, and is included in "other long-term liabilities" in the accompanying consolidated balance sheets. The Company estimates that approximately $18.3 million of derivative losses (net of tax benefit) included in other comprehensive loss will be reclassified into the statement of operations within the next twelve months. 6. Acquisitions General--The acquisitions consummated during the three month period ended March 31, 2002 have been accounted for by the purchase method of accounting. The purchase prices have been allocated to the net assets acquired, principally intangible and tangible assets, and the liabilities assumed based on their estimated fair values at the date of acquisition. The excess of purchase price over the estimated fair value of the net assets acquired has been recorded as goodwill and other intangible assets. For certain acquisitions, the condensed consolidated financial statements reflect the preliminary allocation of purchase prices, as the appraisals of assets acquired have not been finalized. The Company does not expect any changes in depreciation and amortization as a result of such appraisals to be material to the Company's consolidated results of operations. During the three month period ended March 31, 2002, the Company acquired various communication sites for an aggregate preliminary purchase price of approximately $16.8 million. This includes amounts paid by the Company in connection with our agreement with ALLTEL. The following summarizes the ALLTEL transaction to date. ALLTEL transaction--In December 2000, the Company entered into an agreement to acquire the rights from ALLTEL to up to 2,193 communications towers through a fifteen-year sublease agreement. Under the agreement, the Company subleased these towers for cash consideration of up to $657.9 million. The Company also has the option to purchase the towers at the end of the fifteen-year term. The purchase price per tower will be $27,500 plus interest accrued at 3% per annum or 769 shares of the Company's Class A common stock, at ALLTEL's option. During the three months ended March 31, 2002, the Company subleased 28 towers and paid ALLTEL $8.4 million, bringing the total towers closed under the agreement to 1,773 and total cash paid to ALLTEL of $532.2 million. The Company will not close on the remaining 417 towers under the sublease agreement, as permitted by the agreement. The Company has accounted for the ALLTEL transaction as a capital lease. The unaudited pro forma results of operations for the three months ended March 31, 2002 and 2001 are not presented for comparative purposes due to the insignificant impact of the 2002 acquisitions (as described above) on the Company's consolidated results of operations. As of December 31, 2001, the Company had a liability of approximately $2.8 million related to contractual obligations assumed as a result of its acquisition of InterPacket Networks in 2000. During the three months ended March 31, 2002, the Company recorded charges against this liability of approximately $0.1 million. As of March 31, 2002, the Company has a remaining liability related to these assumed obligations of $2.7 million. The Company may, on a selective, limited basis, pursue the acquisition of other properties and businesses in new and existing locations, although we have not entered into any definitive material agreements with respect to such acquisitions. 7

AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--Unaudited--(Continued) 7. Business Segments The Company operates in three business segments: rental and management (RM), network development services (Services), and satellite and fiber network access services (SFNA). The RM segment provides for the leasing and subleasing of antennae sites on multi-tenant towers and other properties to a diverse range of customers primarily in the wireless communication and broadcast and other industries. The Services segment offers a broad range of services, including network design, radio frequency engineering, site acquisition, zoning, construction, component parts, antenna and line installation, maintenance, tower monitoring and steel fabrication. The SFNA segment offers satellite and fiber network services to telecommunications companies, internet service providers, governmental organizations, broadcasters and maritime customers. The accounting policies applied in compiling segment information below are similar to those described in the Company's 2001 Annual Report on Form 10-K. In evaluating financial performance, management focuses on Operating Profit (Loss), excluding depreciation and amortization, corporate general and administrative, restructuring, and development expenses and net gain on sale of assets. This measure of Operating Profit (Loss) is also before interest income, interest expense, loss on term loan cancellation, loss on investments and other expense, minority interest in net earnings of subsidiaries, income taxes and extraordinary loss. For reporting purposes, the RM segment includes interest income, TV Azteca, net. The Company's reportable segments are strategic business units that offer different services. They are managed separately because each segment requires different resources, skill sets and marketing strategies. Summarized financial information concerning the Company's reportable segments as of and for the three months ended March 31, 2002 and 2001 is shown in the following table. The "Other" column below represents amounts excluded from specific segments, such as depreciation and amortization, corporate general and administrative, restructuring and development expenses, net gain on sale of assets, interest income, interest expense, loss on term loan cancellation, loss on investments and other expense, minority interest in net earnings of subsidiaries, income taxes and extraordinary loss. In addition, the Other column also includes corporate assets such as cash and cash equivalents, certain tangible and intangible assets and income tax accounts that have not been allocated to specific segments. All amounts shown are in thousands.

As a result of this termination, in the first quarter of 2002, the Company recorded a non-cash charge of approximately $7.2 million related to the write-off of certain deferred financing fees associated with this facility. Such loss is included in "loss on term loan cancellation" in the accompanying 2002 consolidated statement of operations. In February 2002, the Company repaid the $95.0 million outstanding under its Mexican Credit Facility with borrowings under its credit facility. As a result of such repayment, the Company recognized an extraordinary loss on extinguishment of debt in the first quarter of 2002 of approximately $1.1 million (net of an income tax benefit of $0.6 million). 8

Commitments and Contingencies Litigation--The Company periodically becomes involved in various claims and lawsuits that are incidental to its business. In the opinion of management, after consultation with counsel, there are no matters currently pending which would, in the event of an adverse outcome, have a material impact on the Company's consolidated financial position, the results of its operations or liquidity. ATC Separation--The Company was a wholly-owned subsidiary of American Radio Systems Corporation (American Radio) until consummation of the spin-off of the Company from American Radio on June 4, 1998 (the ATC Separation). On June 4, 1998, the merger of American Radio and a subsidiary of CBS Corporation (CBS) was consummated. As a result of the merger, all of the outstanding shares of the Company's common stock owned by American Radio were distributed or reserved for distribution to American Radio stockholders, and the Company ceased to be a subsidiary of, or to be otherwise affiliated with, American Radio. Furthermore, from that day forward the Company began operating as an independent publicly traded company. As part of the ATC Separation, the Company was required to reimburse CBS for certain tax liabilities incurred by American Radio as a result of the transaction. Upon completion of the final American Radio tax filings, a calculation of the total tax payments due to CBS was performed and approved by both the Company and CBS. The Company continues to be obligated to indemnify CBS and American Radio for certain tax matters affecting American Radio prior to the ATC Separation. As of March 31, 2002, no material matters covered under this indemnification have been brought to the Company's attention. Tower Acquisitions--As of March 31, 2002, the Company is party to agreements relating to the acquisition of assets for a purchase price of approximately $13.8 million. 12. Restructuring In November 2001, the Company announced a restructuring of its organization to include a reduction in the scope of its tower development and acquisition activities and the centralization of certain operating and administrative functions. As of December 31, 2001, the Company had a remaining liability of $3.6 million related to these restructuring initiatives announced and implemented in the fourth quarter of 2001. During the 10

AMERICAN TOWER CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--Unaudited--(Continued) first quarter of 2002, the Company committed to and implemented additional restructuring initiatives related to the consolidation of operations. As a result, the Company incurred employee separation costs associated with the termination of approximately 185 employees (primarily development and adminstration) and facility closing costs associated with the shut-down of five office locations. As a result of these initiatives, the Company recorded approximately $3.8 million of cash restructuring charges during the three months ended March 31, 2002. The following table displays activity related to the accrued restructuring liability. Such liability is reflected in accounts payable and accrued expenses in the accompanying consolidated balance sheet as of March 31, 2002 (in thousands): Liability as of Liability as of Restructuring Cash March 31, January 1, 2002 Expense Payments 2002 --------------- ------------- -------- --------- Restructuring costs Employee separations..................................... $ 923 $2,049 $(1,697) $1,275 Office closings (primarily real estate lease obligations) 2,704 1,716 (2,047) 2,373 ------ ------ ------- ------ Total.................................................. $3,627 $3,765 $(3,744) $3,648 ====== ====== ======= ====== There were no material changes in estimates related to the accrued restructuring liability during the quarter ended March 31, 2002. 13. Subsequent Events Restructuring--In the second quarter of 2002, the Company announced and began implementing additional cost reduction initiatives aimed at reducing infrastructure costs, consolidating transponder space and renegotiating certain transponder agreements. These initiatives are expected to continue throughout the second and third quarters of 2002. As a result, the Company expects to incur additional restructuring charges of approximately $12.0 million to $15.0 million over this period. 11

The increase resulted primarily from two factors: the leasing activity on towers acquired and constructed subsequent to January 1, 2001 and increased same tower revenue on towers that existed as of January 1, 2001. Our acquisition, construction and leasing activity since January 1, 2001 has significantly increased revenue and the scope, depth and strength of our national and international tower portfolio, providing us with a much larger base of tower revenue in the first quarter 2002 as compared to the first quarter 2001. Specifically, from the period January 1, 2001 to March 31, 2002, we acquired approximately 2,400 towers and constructed more than 1,400 towers. Additionally, during that same period, we added approximately 4,500 broadband equivalent tenants to both newly acquired/constructed and existing towers. This leasing activity resulted in a 20% increase in same tower revenue for towers that existed as of January 1, 2001 and contributed to revenue growth on our newly acquired/constructed towers. We continue to believe that our leasing revenues, which comprise our core business, are likely to grow at a more rapid rate than revenues from other segments of our business because of increasing utilization of existing tower capacity, recent acquisitions and build-to-suit and other construction activities. In addition, we also believe that the majority of our leasing activity will continue to come from broadband-type customers. 13

Network Development Services Revenue Network development services revenue for the three months ended March 31, 2002 was $82.1 million, a decrease of $24.4 million from the three months ended March 31, 2001. The decrease in revenues during the three months ended March 31, 2002 resulted primarily from decreases in revenue related to construction management, installation, tower maintenance services and RF engineering services as a result of the downturn in the telecommunications industry. Satellite and Fiber Network Access Services Revenue Satellite and fiber network access services revenue for the three months ended March 31, 2002 was $57.9 million, a decrease of $6.9 million from the three months ended March 31, 2001. The decrease in revenue was primarily due to the loss of many second and third tier telecom customers, partially offset by incremental revenues from government, broadcast and other first tier customers. We expect some continued churn of certain second and third tier telecom customers throughout 2002 as we shift our revenue base to higher quality customers. Rental and Management Expense Rental and management expense for the three months ended March 31, 2002 was $58.7 million, an increase of $13.2 million from the three months ended March 31, 2001. The majority of the increase resulted from incremental operating expenses incurred in the three months ended March 31, 2002 for the more than 3,800 towers that were acquired or constructed from the period January 1, 2001 to March 31, 2002, as discussed above. The balance of the increase reflects higher operating expenses for the three months ended March 31, 2002 related to towers that existed as of March 31, 2001 (due to a full quarter of inclusion in our results of operations in 2002). Network Development Services Expense Network development services expense for the three months ended March 31, 2002 was $76.0 million, a decrease of $20.5 million from the three months ended March 31, 2001. The decrease is primarily due to overall decreases in the volume discussed above coupled with decreases in direct and indirect costs. Satellite and Fiber Network Access Services Expense Satellite and fiber network access services expense for the three months ended March 31, 2002 was $57.5 million, an increase of $1.2 million from the three months ended March 31, 2001. The primary reason for the increase relates to increased bad debt expense associated with the erosion of the first and second tier customer base as well as additional transponder capacity and other infrastructure related expenses. Depreciation and Amortization Depreciation and amortization for the three months ended March 31, 2002 was $93.1 million, a decrease of $1.9 million from the three months ended March 31, 2001. The net decrease reflects a reduction in amortization expense of approximately $24.0 million related to the Company's adoption of SFAS No. 142, partially offset by an increase in depreciation and amortization related to its acquisition/construction of approximately $1.3 billion of property and equipment and intangible assets from the period April 1, 2001 to March 31, 2002. The adoption of SFAS No. 142 is expected to reduce the Company's annual amortization expense by approximately $96.0 million. Corporate General and Administrative Expense Corporate general and administrative expense for the three months ended March 31, 2002 was $6.8 million, an increase of $1.7 million from the three months ended March 31, 2001. The majority of the increase reflects increased information technology and personnel costs related to supporting the Company's corporate structure. 14

Restructuring expense In November 2001, the Company announced a restructuring of its organization to include a reduction in the scope of its tower development and acquisition activities and the centralization of certain operating and administrative functions. During the first quarter of 2002, the Company committed to and implemented additional restructuring initiatives related to the consolidation of operations. As a result, the Company incurred employee separation costs associated with the termination of approximately 185 employees (primarily development and administration) and facility closing costs associated with the shut-down of five office locations. As a result of these initiatives, the Company recorded approximately $3.8 million of cash restructuring charges during the three months ended March 31, 2002. No similar charges were incurred for the same period in 2001. In the second quarter of 2002, the Company announced and began implementing cost reduction initiatives aimed at reducing infrastructure costs, consolidating transponder space and renegotiating certain transponder agreements. These initiatives are expected to continue throughout the second and third quarters of 2002. As a result, the Company expects to incur additional restructuring charges of approximately $12.0 million to $15.0 million over this period. Development Expense Development expense for the three months ended March 31, 2002 was $2.4 million, a decrease of $0.3 million from the three months ended March 31, 2001. The majority of the decrease results from reduced expenses related to tower site inspections, data gathering and acquisition integration in the three months ended March 31, 2002, offset by costs associated with acquisitions that were abandoned during the three months ended March 31, 2002. Net gain on sale of assets The Company sold 265 towers during the three months ended March 31, 2002 and recognized a net gain on sale of assets of approximately $3.7 million. No similar transactions were consummated in the same period in 2001. Interest Income Interest income for the three months ended March 31, 2002 was $1.1 million, a decrease of $11.6 million from the three months ended March 31, 2001. The decrease relates primarily to a decrease in cash on-hand and interest earned on invested cash on-hand. Interest Expense Interest expense for the three months ended March 31, 2002 was $67.6 million, an increase of $0.9 million from the three months ended March 31, 2001. The increase resulted primarily from increased borrowings outstanding related to our credit facilities and senior notes, partially offset by a decrease in interest rates on our credit facilities and decreased deferred financing amortization. Loss on Term Loan Cancellation In January 2002, the Company terminated the $250.0 million multi-draw term loan C component of its credit facility and recorded a non-cash charge of approximately $7.2 million related to the write-off of certain deferred financing fees associated with the facility. No similar charge was incurred for the three months ended March 31, 2001. 15

Loss on Investments and Other Expense Loss on investments and other expense for the three months ended March 31, 2002 was $5.9 million, an increase of $1.7 million from the three months ended March 31, 2001. The increase resulted primarily from investment impairment losses of approximately $4.0 million offset by a decrease in losses on equity investments and other expenses. Income Tax Benefit The income tax benefit for the three months ended March 31, 2002 was $30.0 million, an increase of $7.9 million from the three months ended March 31, 2001. The primary reason for the increase is a result of the increase in our pre-tax loss of approximately $30.0 million before consideration of goodwill amortization. The effective tax rate differs in both periods from the statutory rate primarily due to the valuation allowance related to our state net operating loss carryforwards and the effect of certain non-deductible items. In 2001, the statutory rate was also impacted by non-deductible goodwill being expensed for book purposes. The increase in the effective tax rate of 29.8% for the three months ended March 31, 2002 as compared to 23.6% for the three months ended March 31, 2001 is the result of ceasing amortization of goodwill (the majority of which was non-deductible for tax purposes) in 2002. SFAS No. 109, "Accounting for Income Taxes," requires that we record a valuation allowance when it is "more likely than not that some portion or all of the deferred tax assets will not be realized." At March 31, 2002, the Company has provided a valuation allowance primarily related to state net operating loss carryforwards. The Company has not provided a valuation allowance for the remaining deferred tax assets, primarily federal net operating loss carryforwards, as management believes that the Company will have sufficient time to realize these assets during the carryforward period. Extraordinary Loss on Extinguishment of Debt, Net In February 2002, the Company repaid the $95.0 million outstanding under its Mexican Credit Facility with borrowings under its credit facilities. As a result of such repayment, the Company recognized an extraordinary loss on extinguishment of debt of approximately $1.1 million, net of an income tax benefit of $0.6 million. No similar loss was incurred in the three months ended March 31, 2001. Liquidity and Capital Resources Overview We plan to fund our current business plan with cash generated from our operations and by borrowing under our credit facilities. Historically, we have met our operational liquidity needs and interest expense related to our debt obligations primarily with internally generated funds. We have financed our tower acquisitions and construction activities with a combination of capital funds from sales of our equity and debt securities and bank borrowings. We expect that during 2003 we will become free cash flow positive, meaning that our operating cash flows will be sufficient to meet our operational needs, interest expense and capital expenditures. We believe we will have more than sufficient liquidity and capital resources from our operating cash flows and available borrowings under our credit facilities to support our business plan until that occurs. Uses of Liquidity Our uses of liquidity include: operational needs; capital expenditures for tower construction and acquisitions; and debt service. 16

Tower Construction and Acquisition Needs. We have significantly reduced our planned level of tower construction and acquisitions for 2002. As a result, we anticipate that our liquidity needs for new tower development and acquisitions in 2002 will be significantly less than in previous years. . Tower Construction. Our 2002 capital plan provides for total capital expenditures of approximately $200.0 million to $225.0 million, which includes towers to be built under existing build-to-suit agreements. In 2002, we plan to build between 400 and 500 towers, including nine broadcast towers. During the three months ended March 31, 2002, we built 104 towers, including two broadcast towers. Capital expenditures incurred in the three months ended March 31, 2002 were approximately $58.0 million. . Tower Acquisitions. As of March 31, 2002, we were committed to make capital expenditures of approximately $13.8 million for pending acquisitions. Debt Service. We use a significant portion of our liquidity to service our outstanding indebtedness. As of March 31, 2002, we had outstanding total long-term debt of about $3.6 billion, consisting primarily of the following: . credit facilities-$1.5 billion; . senior notes-$1.0 billion; and . convertible notes, net of discount-$868.5 million. Our credit facilities, senior notes and convertible notes require us to make significant principal payments at their respective maturity dates. In addition, in the case of our credit facilities, we must make scheduled amortization payments of principal prior to maturity. Beginning March 31, 2003, our credit facilities require amortization of the term loans in increasing annual amounts designed to repay the loans by maturity. Interest on our senior notes is payable semiannually on February 1 and August 1. Under our credit facilities, we are required to maintain an interest reserve for our senior notes through the August 2002 interest payment. These funds can only be used to make scheduled interest payments on those notes. As of March 31, 2002, we had approximately $47.5 million of restricted cash related to this interest reserve. Interest on our convertible notes is payable semi-annually. Prior to maturity, there are no mandatory redemption provisions for cash in the senior notes or the convertible notes. The holders of the convertible notes, however, have the right to require us to repurchase their notes on specified dates prior to maturity, but we may at our election pay the repurchase price in cash or by issuing shares of our Class A common stock. Our credit facilities restrict our ability to repurchase the convertible notes for cash. Sources of Liquidity Our primary sources of liquidity historically have been internally generated funds from operations, borrowings under our credit facilities, proceeds from equity and debt offerings and cash on hand. Internally Generated Funds. Our operating revenues, divisional cash flows/*/ and EBITDA/**/ for the three months ended March 31, 2002 were $270.3 million, $81.6 million and $74.8 million, respectively. Our tower leasing activities generate the highest profit margins. We believe those activities are likely to grow more rapidly than our other segments because of increased utilization of our existing towers. EBITDA and divisional cash flow are not measures of performance or profitability under generally accepted accounting principles (GAAP) in the United States. However, they are commonly used in the communications site industry as a measure of a company's operating performance. More specifically, we believe they can assist in comparing company performances on a consistent basis without regard to depreciation and amortization. Our concern is that - -------- * Divisional cash flows means operating loss before depreciation and amortization, corporate general and administrative expense, restructuring expense, development expense and net gain on sale of assets, plus interest income, TVAzteca, net. ** EBITDA means operating loss before depreciation and amortization, restructuring and development expenses and net gain on sale of assets, plus interest income, TVAzteca, net. 17

depreciation and amortization can vary significantly among companies depending on accounting methods, particularly where acquisitions or non-operating factors including historical cost bases are involved. Our results under GAAP are set forth in the condensed consolidated financial statements herein. Credit Facilities. As of March 31, 2002, we had drawn $145.0 million on the $650.0 million revolving line of credit under our credit facilities. As of March 31, 2002, based on financial covenants, we had the ability to draw $455.0 million on this revolving line of credit. Because of existing cash on hand, our anticipated borrowing needs and the unused capacity in our credit facilities, in January 2002, we chose to cancel our incremental $250.0 million term C Loan. As a result, our maximum borrowing capacity under the credit facilities was reduced from $2.25 billion to $2.0 billion. Cash On Hand. As of March 31, 2002, we had approximately $77.1 million in cash and cash equivalents and restricted cash. Approximately $47.5 million is restricted under our credit facilities and can only be used to make scheduled interest payments on the senior notes. As of March 31, 2002, we had approximately $130.6 million of working capital. Plans to Fund Our Liquidity Needs We plan to fund our operational liquidity needs through internally generated funds from operations. We plan to fund our capital expenditures for new tower construction and acquisitions and our interest expense through a combination of internally generated funds and borrowings under our credit facilities. We anticipate aggregate incremental borrowing needs for the remainder of 2002 and 2003 of under $150.0 million. During 2003, we expect that our operating cash flows will become sufficient to fund both our capital expenditures for new tower construction and acquisitions and the interest expense on our outstanding debt. Nonetheless, we may, in the future, need to raise cash from external sources to meet our debt service obligations and to pay the principal amounts of our indebtedness when due. Certain Contractual Commitments Below is a summary of our credit facilities, senior notes, convertible notes and certain other contractual obligations. It is qualified in its entirety by the terms of the actual agreements which are summarized. For more information about our obligations, commitments and contingencies, see our condensed consolidated financial statements herein and the accompanying notes thereto, as well as our Form 10-K for the year ended December 31, 2001 and Item 3 "Quantitative and Qualitative Disclosures About Market Risk" for principal payments and contractual maturity dates as of March 31, 2002. Credit Facilities. Our credit facilities provide us with a borrowing capacity of up to $2.0 billion, with the option, subject to lender approval, to increase the capacity up to an additional $500.0 million. Our principal operating subsidiaries are the borrowers under our credit facilities. Borrowings under the credit facilities are subject to compliance with certain financial ratios as described below. Our credit facilities currently include: . a $650.0 million revolving credit facility of which $145.0 million was drawn on March 31, 2002, maturing on June 30, 2007; . an $850.0 million multi-draw Term Loan A, which was fully drawn on March 31, 2002, maturing on June 30, 2007; and . a $500.0 million Term Loan B, which was fully drawn on March 31, 2002, maturing on December 31, 2007. 18

The credit facilities are scheduled to amortize quarterly commencing in March 2003. In January 2002, we terminated the $250.0 million multi-draw term loan C component of our credit facility, none of which had been drawn. As a result of this termination, in the first quarter of 2002, we recorded a non-cash charge of approximately $7.2 million related to the write-off of certain deferred financing fees. Such loss is included in "loss on term loan cancellation" in the accompanying consolidated statement of operations. As of March 31, 2002, we believe the $455.0 million available of the $505.0 million remaining under the $650.0 million revolving credit facility will be sufficient to finance our business plan. Our credit facilities contain certain financial ratios and operational covenants and other restrictions with which the borrower subsidiaries and the restricted subsidiaries must comply. Any failure to comply with these covenants would not only prevent us from being able to borrow more funds, but would also constitute a default. For more information about these covenants, see "Factors Affecting Sources of Liquidity--Credit Facilities". They also restrict our ability, as the parent company of the borrower subsidiaries, to incur any debt other than that presently outstanding and refinancings of that debt. We and our 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 substantially all outstanding capital stock and other debt and equity interests of all of our direct and indirect subsidiaries. Under our credit facilities, we are also required to maintain an interest reserve for our senior notes through the August 2002 interest payment. These funds can only be used to make scheduled interest payments on those notes. As of March 31, 2002 we had approximately $47.5 million of restricted cash related to that interest reserve. In February 2001, our Mexican subsidiary and two of its subsidiaries consummated a loan agreement with a group of banks providing a credit facility of an initial aggregate amount of $95.0 million. As of December 31, 2001, an aggregate of $95.0 million was outstanding under this loan agreement. In February 2002, we repaid all of the loans with borrowings under our credit facilities, and our Mexican subsidiaries became restricted subsidiaries under our credit facilities. As a result of such repayment, we recognized an extraordinary loss on extinguishment of debt in the first quarter of 2002 of approximately $1.1 million (net of an income tax benefit of $0.6 million). 9 3/8% Senior Notes. As of March 31, 2002, we had outstanding an aggregate principal amount of $1.0 billion of 9 3/8 % senior notes. The senior notes mature on February 1, 2009. Interest on the senior notes is payable semiannually on February 1 and August 1. The indenture governing the senior notes contains certain restrictive covenants, including restrictions on our ability to incur more debt, guarantee debt, pay dividends and make certain investments. October 1999 Convertible Notes. In October 1999, we issued 6.25% convertible notes due 2009 in an aggregate principal amount of $300.0 million and 2.25% convertible notes due 2009 at an issue price of $300.1 million, representing 70.52% of their principal amount at maturity of $425.5 million. The difference between the issue price and the principal amount at maturity of the 2.25% convertible notes will be accreted each year as interest expense in our consolidated financial statements. The 6.25% convertible notes are convertible into shares of Class A common stock at a conversion price of $24.40 per share. The 2.25% convertible notes are convertible into shares of Class A common stock at a conversion price of $24.00 per share. The indentures under which the convertible notes 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. We may not redeem the 6.25% convertible notes prior to October 22, 2002. Thereafter, we can redeem the 6.25% convertible 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% convertible notes prior to October 22, 19

2003. Thereafter, we can redeem the 2.25% convertible notes, at our option, in whole or in part at increasing redemption prices designed to reflect the original issue discount. We are also required to pay accrued and unpaid interest in all redemptions of notes. Holders may require us to repurchase all or any of their 6.25% convertible notes on October 22, 2006 at their principal amount, together with accrued and unpaid interest. Holders may require us to repurchase all or any of their 2.25% convertible notes on October 22, 2003 at $802.93, which is its issue price plus accreted original issue discount, together with accrued and unpaid interest. We may, at our option, elect to pay the repurchase price of each series in cash or shares of Class A common stock, or any combination thereof. Our credit facilities restrict our ability to repurchase the convertible notes for cash. During 2001, we acquired portion of our outstanding convertible notes. As a result of these transactions, we recorded a non-cash charge of $26.3 million, which represents the fair market value of the inducement shares. We may negotiate similar exchanges for our outstanding convertible notes from time to time in the future, subject to market conditions. To the extent that we issue inducement shares as part of any future exchanges, we expect to record additional non-cash charges. As of March 31, 2002, the total amounts outstanding under the 2.25% and 6.25% convertible notes were $205.8 million and $212.7 million, respectively. February 2000 Convertible Notes. In February 2000, we issued 5.0% convertible notes due 2010 in an aggregate principal amount of $450.0 million. The 5.0% convertible notes are convertible into shares of our Class A common stock at a conversion price of $51.50 per share. The indenture under which the 5.0% convertible notes are outstanding does not contain any restrictions on the payment of dividends, the incurrence of debt or the repurchase of our equity securities or any financial covenants. We may not redeem the 5.0% convertible notes prior to February 20, 2003. Thereafter, we can redeem the 5.0% convertible 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 notes. Holders may require us to repurchase all or any of the 5.0% convertible notes on February 20, 2007 at their principal amount, together with accrued and unpaid interest. We may, at our option, elect to pay the repurchase price in cash or shares of Class A common stock or any combination thereof. Our credit facilities restrict our ability to repurchase the notes for cash. The total amount outstanding under the 5.0% convertible notes as of March 31, 2002 was $450.0 million. Other Long-Term Debt. As of March 31, 2002, we had approximately $246.2 million of other long-term debt, including $173.4 million of capital lease obligations and $72.8 million of mortgage indebtedness. Tower Construction and Acquisition. As of March 31, 2002, we were party to various arrangements relating to the construction of tower sites under existing build-to-suit agreements. In addition, as of March 31, 2002, we were committed to acquire various communication sites for aggregate purchase price of approximately $13.8 million. ATC Separation. We continue to be obligated under the ATC Separation agreement for certain tax liabilities to CBS corporation and American Radio Systems. As of March 31, 2002, no material matters covered under the indemnification have been brought to our attention. See note 11 to the condensed consolidated financial statements. 20

Liquidity Table For Contractual Obligations. See the Company's Form 10-K for the year ended December 31, 2001 for the table with respect to long term obligations as of December 31, 2001. Factors Affecting Sources of Liquidity Internally Generated Funds. The key factors affecting our internally generated funds are the demand for antennae space on wireless communication towers and for related services, our ability to maximize the utilization of our existing towers and our ability to minimize costs and fully realize our operating efficiencies. Credit Facilities. Our credit facilities contain borrowing ratio covenants that limit our ability to borrow funds. Our credit facilities contain four financial tests: . a leverage ratio (Total Debt to Annualized Operating Cash Flow). As of March 31, 2002, we were required to maintain a ratio of not greater than 7.50 to 1.00, decreasing to 7.00 to 1.00 on April 1, 2002, to 6.75 to 1.00 on July 1, 2002, to 6.50 to 1.00 at October 1, 2002, and with additional reductions every six months thereafter; . a pro forma debt service test (Annualized Operating Cash Flow to Pro Forma Debt Service) requires us to maintain a ratio of not greater than 1.10 to 1.00; . an interest coverage test (Annualized Operating Cash Flow to Interest Expense). As of March 31, 2002, we were required to maintain a ratio of not less than 1.50 to 1.00 through June 30, 2002, increasing by 0.25 on July 1, 2002 and October 1, 2002, and by 0.50 on January 1, 2003 and January 1, 2004; and . a fixed charge coverage test (Annualized Operating Cash Flow to Fixed Charges) which begins in 2003 and requires us to maintain a ratio of not less than 1.0 to 1.0. Since our credit facilities are with certain of our subsidiaries, our parent company debt (the senior notes and the convertible notes) is not included in the computations of any of the tests, except in the case of the pro forma debt service test in which case interest includes the amount of funds that we will require to be distributed by our subsidiaries to pay interest on our senior notes and our convertible notes. Annualized Operating Cash Flow is based, among other things, on four times the Operating Cash Flow for the most recent quarter of our tower rental and management business and trailing 12 months for our other businesses and corporate general and administrative expenses. In the case of the leverage ratio, we may include the Operating Cash Flow from Brazil and Mexico only to the extent of 10% of Annualized Operating Cash Flow and we receive credit for only 75% of Annualized Operating Cash Flow from our services and Verestar businesses. As of March 31, 2002, we were in compliance with these borrowing ratio covenants. Senior Notes. Our senior note indenture restricts us from incurring additional debt or issuing certain types of preferred stock unless our Consolidated Debt is not greater than 7.5 times our Adjusted Consolidated Cash Flow. However, we are permitted, even if we are not in compliance with the ratio, to incur debt under our credit facilities, or renewals, refundings, replacements or refinancings of them, up to the greater of $2.65 billion or a formula based on the number of towers we own and our Non-Tower Cash Flow. Even if not in compliance with the ratio, we are also permitted to, among other things, have certain types of capital leases and to refund our convertible notes. For these purposes, Consolidated Debt means all debt, including guarantees, of our parent company and all of our restricted subsidiaries, which presently include all of them, other than Verestar and its subsidiaries, and the aggregate liquidation value of Disqualified Stock. Disqualified Stock means capital stock maturing, mandatorily redeemable, or redeemable at the holder's option, prior to 91 days after the maturity of the senior notes. Adjusted Consolidated Cash Flow is substantially similar to the definition of Annualized Operating Cash Flow, as defined in the credit facilities, except it applies to our parent company and our restricted subsidiaries. 21

Capital Markets. Our ability to raise additional funds in the capital markets depends on, among other things, general economic conditions, the condition of the wireless industry, our financial performance and the state of the capital markets. Cash Flows Summary For the three months ended March 31, 2002, cash flows used for operating activities were $8.0 million, as compared to $24.2 million for the three months ended March 31, 2001. This change is primarily related to a decrease in our overall investment in working capital. For the three months ended March 31, 2002, cash flows used for investing activities were $90.8 million, as compared to $402.7 million for the three months ended March 31, 2001. The decrease is primarily due to a decrease in cash expended for mergers and acquisitions, construction activities and other long term assets. For the three months ended March 31, 2002, cash flows provided by financing activities were $92.5 million, as compared to $1.3 billion for the three months ended March 31, 2001. The decrease is primarily related to a reduction in the aggregate net cash inflows from bank borrowings and proceeds from the issuance of debt and equity securities. Critical Accounting Policies In the Company's Form 10-K for the year ended December 31, 2001, the Company's most critical accounting policies and estimates upon which our consolidated financial statements were prepared were identified as those relating to revenue recognition, income taxes, impairment of assets and investment impairment charges. We reviewed our policies and determined that they remain our most critical accounting policies for the quarter ended March 31, 2002. We did not make any changes to those policies during the quarter. Recent Accounting Pronouncements On January 1, 2002, the Company adopted the provisions of Statement of Financial Accounting Standard (SFAS) No. 142 "Goodwill and Other Intangible Assets.'' SFAS No. 142 supersedes APB Opinion No. 17, "Intangible Assets," and requires that goodwill and intangible assets with indefinite lives no longer be amortized, but reviewed for impairment at least annually. Intangible assets that are deemed to have a definite life will continue to be amortized over their useful lives. The adoption of this statement reduced the Company's amortization expense and net loss by approximately $24.0 million or $0.12 per share for the three months ended March 31, 2002. The adoption of SFAS No. 142 is expected to reduce the Company's annual amortization of expense by approximately $96.0 million. The Company is in the process of assessing the transitional impairment test and the related valuation of goodwill under SFAS No. 142 for the Company as a whole. However, upon completion of the transitional impairment test, the Company believes it will record a non-cash impairment charge in its statement of operations related to goodwill within its SFNA segment and its Services segment. Although the amount of the charges has not been determined, net goodwill related to the SFNA segment and the Services segment as of March 31, 2002 was approximately $188.0 million and $400.3 million, respectively. These charges will be reflected as a cumulative effect of a change in accounting principle in the Company's 2002 statement of operations. In August 2001, the Financial Accounting Standards Board ("FASB") issued SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." This statement supercedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of." The statement retains the previously existing accounting requirements related to the recognition and measurement of the impairment of long-lived assets to be held and used while expanding the measurement requirements of long-lived assets to be disposed 22

of by sale to include discontinued operations. It also expands the previously existing reporting requirements for discontinued operations to include a component of an entity that either has been disposed of or is classified as held for sale. The Company implemented SFAS No. 144 on January 1, 2002. The adoption of this statement did not have a material impact on the Company's consolidated financial position or results of operations. In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement Obligations." This statement establishes accounting standards for the recognition and measurement of liabilities associated with the retirement of tangible long-lived assets and the related asset retirement costs. The requirements of SFAS No. 143 are effective for the Company as of January 1, 2003. The Company is currently evaluating the impact, if any, that the statement may have on its consolidated financial position or results of operations. Factors That May Affect Future Results We operate in a rapidly changing environment that involves a number of risks, some of which are beyond our control. The following discussion highlights some of the risks that may affect future operating results. DECREASE IN DEMAND FOR TOWER SPACE WOULD MATERIALLY AND ADVERSELY AFFECT OUR OPERATING RESULTS AND WE CANNOT CONTROL THAT DEMAND. Many of the factors affecting the demand for tower space, and to a lesser extent our services business, materially affect our operating results. Those factors include: . consumer demand for wireless services; . the financial condition of wireless service providers and their preference for owning rather than leasing antenna sites; . the ability and willingness of wireless service providers to maintain or increase their capital expenditures; . the growth rate of wireless communications or of a particular wireless segment; . the number of wireless service providers in a particular segment, nationally or locally; . governmental licensing of broadcast rights; . mergers or consolidations among wireless service providers; . increased use of network sharing arrangements or roaming and resale arrangements by wireless service providers; . delays or changes in the deployment of 3G or other technologies; . zoning, environmental, health and other government regulations; and . technological changes. The demand for antenna space is dependent, to a significantly lesser extent, on the needs of television and radio broadcasters. Among other things, technological advances, including the development of satellite-delivered radio, may reduce the need for tower-based broadcast transmission. We could also be affected adversely should the development of digital television be delayed or impaired, or if demand for it were to be less than anticipated because of delays, disappointing technical performance or cost to the consumer. 23

Continuation of the current U.S. economic slowdown could materially and adversely affect our business. The existing slowdown in the economy has negatively affected the factors described under the prior heading, influencing demand for tower space and tower related services. For example, the slowdown, coupled with the deterioration of the capital markets, has caused certain wireless service providers to delay and, in certain cases, abandon expansion and upgrading of wireless networks, implementation of new systems, or introduction of new technologies. The economic slowdown has also harmed, and may continue to harm, the financial condition of some wireless service providers. Many wireless service providers operate with substantial leverage and some wireless service providers, including customers of ours, have filed for bankruptcy. OUR SUBSTANTIAL LEVERAGE AND DEBT SERVICE OBLIGATIONS MAY ADVERSELY AFFECT OUR CASH FLOW AND OUR ABILITY TO MAKE PAYMENTS ON OUR DEBT. We have a substantial amount of outstanding indebtedness. As of March 31, 2002, we had approximately $3.6 billion of consolidated debt. We will be required to borrow additional funds during 2002 to fund our construction program, even at the significantly reduced activity level that we anticipate, and other capital expenditures. We anticipate aggregate incremental borrowing needs for the remainder of 2002 and 2003 of under $150.0 million. Our substantial leverage could have significant negative consequences, including: . our being unable to meet one or more of the financial ratios contained in our debt agreements or to generate cash sufficient to pay interest or principal, including periodic principal amortization payments, which events could result in an acceleration of some or all of our outstanding debt as a result of cross-default provisions; . increasing our vulnerability to general adverse economic and industry conditions; . limiting our ability to obtain additional debt or equity financing; . requiring the dedication of a substantial portion of our cash flow from operations to service our debt, thereby reducing the amount of our cash flow available for other purposes, including capital expenditures; . requiring us to sell debt or equity securities or to sell some of our core assets, possibly on unfavorable terms, to meet payment obligations; . limiting our flexibility in planning for, or reacting to, changes in our business and the industries in which we compete; and . placing us at a possible competitive disadvantage with less leveraged competitors and competitors that may have better access to capital resources. A significant portion of our outstanding debt bears interest at floating rates. As a result, our interest payment obligations on that debt will increase if interest rates increase. RESTRICTIVE COVENANTS IN OUR CREDIT FACILITIES AND OUR SENIOR NOTES COULD ADVERSELY AFFECT OUR BUSINESS BY LIMITING FLEXIBILITY AND CAUSING US TO BREACH OUR TOWER DEVELOPMENT OBLIGATIONS. The indenture for our senior notes and our credit facilities contain restrictive covenants and, in the case of the credit facilities, requirements of complying with certain leverage and other financial tests. These limit our ability to take various actions, including the incurrence of additional debt, and engage in various types of transactions, including mergers and sales of assets. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisition or other opportunities. 24

We are a party to a number of build-to-suit agreements with wireless carriers that obligate us to develop new tower sites at the direction of the wireless carrier, subject to previously agreed upon approval criteria. We do not expect to have the ability to fund our planned level of capital expenditures with our operating cash flows until during 2003 and hence we will need to borrow under our credit facilities until then. To do so, we must comply with various financial tests. If we are not able to fund our capital expenditures through this borrowing under our credit facilities, we might have to attempt to raise money in the debt or equity capital markets. Alternatively, we would be required to dispose of assets on terms that might not be favorable to us or to curtail our construction activities. That curtailment could adversely affect us if it caused us to breach any of our build-to-suit agreements, because we could be subject to penalties, damage claims, and contract terminations. IF OUR WIRELESS SERVICE PROVIDER CUSTOMERS CONSOLIDATE OR MERGE WITH EACH OTHER TO A SIGNIFICANT DEGREE, OUR GROWTH, OUR REVENUE AND OUR ABILITY TO GENERATE POSITIVE CASH FLOWS COULD BE ADVERSELY AFFECTED. Significant consolidation among our wireless service providers customers may result in reduced capital expenditures in the aggregate because the existing networks of many wireless carriers overlap, as do their expansion plans. Similar consequences might occur if wireless service providers engage in extensive sharing or roaming or resale arrangements as an alternative to leasing our antennae space. In December 2001, the FCC announced that the spectrum cap, which previously prohibited wireless carriers from owning more than 45 MHz of spectrum in any given geographical area, would be removed in January 2003. Some wireless carriers may be encouraged to consolidate with each other as a result of this regulatory change and as a means to strengthen their financial condition. Consolidation among wireless carriers would also increase our risk that the loss of one or more of our major customers could materially decrease revenues and cash flows. DUE TO THE LONG-TERM EXPECTATIONS OF REVENUE FROM TENANT LEASES, THE TOWER INDUSTRY IS SENSITIVE TO THE CREDITWORTHINESS OF ITS TENANTS. Due to the long-term nature of our tenant leases, we, like others in the tower industry, are dependent on the continued financial strength of our tenants. During the past two years, several of our customers have filed for bankruptcy, although to date these bankruptcies have not had a material adverse effect on our business or revenues. Many wireless service providers operate with substantial leverage. If one or more of our major lease customers experienced financial difficulties, it could result in uncollectable accounts receivable and our loss of significant customers and anticipated lease revenues. INCREASING COMPETITION IN THE SATELLITE AND FIBER NETWORK ACCESS SERVICES MARKET MAY ADVERSELY AFFECT VERESTAR'S BUSINESS. Verestar competes with other satellite communications companies that provide similar services, as well as other communications service providers. Some of its existing and potential competitors are companies from whom Verestar currently leases satellite and fiber network access in order to provide services to its customers. Increased competition could force Verestar to reduce its fees and may limit its ability to obtain, on economical terms, services that are critical to its business. Verestar's competitors may develop or acquire services that provide functionality similar to that provided by Verestar's services and these competitive services may be offered at significantly lower prices or bundled with other services. Many existing and potential competitors have financial and other resources significantly greater than those available to Verestar. If Verestar cannot offset the loss of second and third tier carrier customers by adding new first tier global telecom providers and government and broadcast customers, its revenues and business prospects will be materially adversely affected. IF OUR CHIEF EXECUTIVE OFFICER LEFT, WE WOULD BE ADVERSELY AFFECTED BECAUSE WE RELY ON HIS REPUTATION AND EXPERTISE. The loss of our chief executive officer, Steven B. Dodge, has a greater likelihood of having a material adverse effect upon us than it would on most other companies of our size because of our reliance on Mr. Dodge's 25

expertise. Our growth strategy is highly dependent on the efforts of Mr. Dodge. Our ability, even when capital markets are more receptive than they presently are, to raise capital also depends significantly on the reputation of Mr. Dodge. You should be aware that we do not have an employment agreement with Mr. Dodge. OUR FOREIGN OPERATIONS COULD CREATE EXPROPRIATION, GOVERNMENTAL REGULATION, FUNDS INACCESSIBILITY, FOREIGN EXCHANGE EXPOSURE AND MANAGEMENT PROBLEMS. Our expansion into Mexico and Brazil, and any other possible foreign operations in the future, could result in adverse financial consequences and operational problems not experienced in the United States. We have made a substantial loan to a Mexican company, own towers in Mexico and are committed to construct a sizable number of towers in that country. We have also acquired the rights to 156 communications towers in Brazil and entered into a build-to-suit agreement to construct towers in that country. We may, should economic and capital market conditions improve, also engage in comparable transactions in other countries in the future. Among the risks of foreign operations are governmental expropriation and regulation, inability to repatriate earnings or other funds, currency fluctuations, difficulty in recruiting trained personnel, and language and cultural differences, all of which could adversely affect our operations. NEW TECHNOLOGIES COULD MAKE OUR TOWER ANTENNA LEASING SERVICES LESS DESIRABLE TO POTENTIAL TENANTS AND RESULT IN DECREASING REVENUES. The development and implementation of signal combining technologies, which permit one antenna to service two different transmission frequencies and, thereby, two customers, may reduce the need for tower-based broadcast transmission and hence demand for our antenna space. Technologies that enhance spectral capacity, such as beam forming or "smart antennas" can increase the capacity at existing sites and can reduce the number of additional sites a given carrier needs to serve any given subscriber base. In addition, the emergence of new technologies could reduce the need for tower-based transmission and reception and have an adverse effect on our operations. The growth in delivery of video services by direct broadcast satellites could also adversely affect demand for our antenna space. Indoor distribution systems relieve some capacity on existing networks and could have an adverse effect on our operations. Capacity enhancing technologies such as lower-rate vocoders and more spectrally efficient airlink standards potentially relieve network capacity problems without adding sites and could adversely effect our operations WE COULD HAVE LIABILITY UNDER ENVIRONMENTAL LAWS. Under various federal, state and local environmental laws, we, as an owner, lessee or operator of more than 14,500 real estate sites may be liable for the substantial costs of remediating soil and groundwater contaminated by hazardous wastes. OUR BUSINESS IS SUBJECT TO GOVERNMENT REGULATIONS AND CHANGES IN CURRENT OR FUTURE LAWS OR REGULATIONS COULD RESTRICT OUR ABILITY TO OPERATE OUR BUSINESS AS WE CURRENTLY DO. We are subject to federal, state and local and foreign regulation of our business. Both the FCC and the FAA regulate towers used for wireless communications and radio and television antennae and, the FCC separately regulates wireless communication devices operating on towers. Similar regulations exist in Mexico, Brazil and other foreign countries regarding wireless communications and the operation of communications towers. Local zoning authorities generally have been hostile to construction in their communities and these regulations can delay or prevent new tower construction, colocations or site upgrade projects, thereby limiting our ability to respond to customer demand. Existing regulatory policies may adversely affect the timing or cost of new tower construction and locations and additional regulations may be adopted which increase delays or result in additional costs to us. These factors could adversely affect our construction program and operations. 26

Our costs could increase and our revenues could decrease due to perceived health risks from radio emissions, especially if these perceived risks are substantiated. Public perception of possible health risks associated with cellular and other wireless communications media could slow the growth of wireless companies, which could in turn slow our growth. In particular, negative public perception of, and regulations regarding, these perceived health risks could slow the market acceptance of wireless communications services. If a connection between radio emissions and possible negative health effects, including cancer, were established, our operations, costs and revenues would be materially and adversely affected. We do not maintain any significant insurance with respect to these matters. Information Presented Pursuant to the Indenture for the Senior Notes The following table sets forth information that is presented solely to address certain reporting requirements contained in the indenture for our Senior Notes. This information presents certain financial data for us on a consolidated basis and on a restricted group basis, which means only for the Company and its subsidiaries that comprise the restricted group under the indenture. All of our subsidiaries are part of this restricted group, except Verestar and its subsidiaries, whose operations constitute all of our satellite and fiber network access services business segment. This restricted group data is not intended to represent an alternative measure of operating results, financial position or cash flow from operations, as determined in accordance with generally accepted accounting principles.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to market risk from changes in interest rates on our long-term debt obligations. We attempt to reduce these risks by utilizing derivative financial instruments, namely interest rate caps, swaps and collars pursuant to our policies. All derivative financial instruments are for purposes other than trading. For the three months ended March 31, 2002, we increased our borrowings under our credit facilities by approximately $50.0 million. In addition, in March 2002 we terminated two swaps with aggregate notional amounts totaling $150.0 million. Lastly, caps with total notional amounts of $365.0 million and swaps with total notional amounts of $30.0 million expired in February and March 2002, respectively. The following table provides information as of March 31, 2002 about our market risk exposure associated with changing interest rates. For long-term debt obligations, the table presents principal cash flows and related average interest rates by contractual maturity dates. For interest rate swaps and collars, the table presents notional principal amounts and weighted-average interest rates by contractual maturity dates.

Interest on the credit facilities is payable in accordance with the applicable London Interbank Offering Rate (LIBOR) agreement or quarterly and accrues at our option either at LIBOR plus margin (as defined) or the Base Rate plus margin (as defined). The average interest rate in effect at March 31, 2002 for the credit facilities was 4.35%. For the three months ended March 31, 2002, the weighted average interest rate under the credit facilities was 4.50%. The 2.25% and 6.25% convertible notes each bear interest (after giving effect to the accretion of the original discount on the 2.25% convertible notes) at 6.25%. Interest on the 2.25% and 6.25% notes is payable semiannually on April 15 and October 15 of each year. The 5.0% convertible notes bear interest at 5.0% which is payable semiannually on February 15 and August 15 of each year. The senior notes bear interest at 9 3/8% which is payable semiannually on February 1 and August 1 of each year. Other debt consists of notes payable, capital leases and other obligations bearing interest at rates ranging from 7.93% to 14.25%, payable monthly.

We maintain a portion of our cash and cash equivalents in financial instruments that are subject to interest rate risks. Due to the relatively short duration of such instruments, fluctuations in interest rates should not materially affect our financial condition or results of operations. Our foreign operations, which primarily include Mexico and Brazil, have not been significant to date. Accordingly, foreign currency risk has not been material for the three months ended March 31, 2002. 29
