American Tower

Overview

We are a leading wireless and broadcast communications infrastructure company with a portfolio of approximately 15,000 towers. Our primary business is leasing antenna space on multi-tenant communications towers to wireless service providers and radio and television broadcast companies. We operate the largest independent portfolio of wireless communications and broadcast towers in North America, based on number of towers and revenue.

Our tower portfolio provides us with a recurring base of leasing revenues from our existing customers and growth potential due to the capacity to add more tenants and equipment to these towers. Our broad network of towers enables us to address the needs of wireless service providers on a national basis. We also offer select tower related services, such as antennae and line installation and site acquisition and zoning services, which are strategic to our leasing business.

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

Our core leasing business, which we refer to as our rental and management segment, accounted for approximately 98.4% and 96.6% of our segment operating profit for the years ended December 31, 2003 and December 31, 2002, respectively. In 2004, we expect that our rental and management segment will contribute approximately 98% of our segment operating profit which, we define as segment revenue less direct segment expense (rental and management segment operating profit includes interest income, TV Azteca, net).

An element of our strategy is to continue to focus our operations on our rental and management segment by divesting non-core assets and businesses, using the proceeds to purchase high quality tower assets, and reducing outstanding indebtedness. Between January 1, 2003 and March 5, 2004, we completed approximately

$123.9 million of non-core asset sales and have or will use the net proceeds to acquire new tower assets and to repay outstanding indebtedness. We expect that we will generate approximately $10.0 million of additional net proceeds in 2004 from the sale of other non-core assets, and intend to reinvest these proceeds in tower assets.

The sales proceeds described above include proceeds from the disposition of our remaining non-core services businesses, including Flash Technologies, Galaxy Engineering and Kline Iron & Steel Co., Inc. (Kline). With the divestiture of Kline in March 2004, we have completed the transformation of our business to a focused tower leasing business with only limited services activities that directly support our core rental and management operations and the addition of new tenants on our towers.

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

•

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

•

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

•

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

•

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

Strategy

Our strategy is to capitalize on the continued increase in the use of wireless communication services and the infrastructure requirements necessary to deploy current and future generations of wireless communication technologies. Between December 2001 and June 2003, the number of wireless phone subscribers in the United States increased from 128.4 million to 148.1 million, representing an increase of approximately 15% and market penetration of approximately 51% at June 30, 2003. From December 2001 through June 2003, the number of cell sites (i.e., the number of antennae and related equipment in commercial operation, not the number of towers on which that equipment is located) also increased from 127,500 to 147,700. With respect to Mexico, the number of wireless phone subscribers increased from approximately 21.5 million at the end of 2001, to approximately 30.4 million at the end of 2003, representing an increase of approximately 41% and market penetration of approximately 30% at December 31, 2003. We expect that the continued growth of subscribers for wireless personal communications and phone services will require wireless carriers to add a significant number of additional cell sites to maintain the performance of their networks in the areas they currently cover and to extend service to areas where coverage does not yet exist. In addition, we believe that as data wireless services, such as email, internet access and video, are deployed on a widespread basis, the deployment of these technologies will require wireless carriers to further increase the cell density of their existing networks, may require an overlay of new technology equipment, and may increase the demand for geographic expansion of their network coverage. To meet this demand, we believe wireless carriers will continue to outsource their tower infrastructure needs as a means of improving existing service coverage, implementing new technology, accelerating access to their markets and preserving capital, rather than constructing and operating their own towers and maintaining their own tower service and development capabilities.

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

•

Maximize Use of Our Tower Capacity. We believe that our highest returns will be achieved by leasing additional space on our existing towers. Annual rental and management revenue and segment operating profit growth during 2003 was approximately 14% and 24%, respectively. We anticipate that our revenues and segment operating profit will continue to grow because many of our towers are attractively located for wireless service providers and have capacity available for additional antenna space rental that we can offer to customers at low incremental costs to us. Because the costs of operating a tower are largely fixed, increasing utilization significantly improves operating margins. We will continue to target our sales and marketing activities to increase utilization of, and investment return on, our existing towers.

•

Actively Manage Our Tower Portfolio. We are actively managing our portfolio of towers by selling non-core towers and reinvesting a portion of the proceeds in high quality tower assets. In 2003, we sold over 300 non-core towers and redeployed a portion of the proceeds from these sales to the acquisition of 525 towers from NII Holdings in Mexico and Brazil. We also plan to pursue exchanges and sales of towers or tower clusters with tower operators and other entities. Our goal is to enhance operating efficiencies either by acquiring towers in regions where we have insufficient coverage or by disposing or exchanging towers in areas where we do not have operating economies of scale. If we are successful in disposing of certain tower assets, we may reinvest a portion of the proceeds received in tower assets that are expected to provide a greater return.

•

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

•

Continue Our Focus on Customer Service and Processes. Because speed to market and reliable network performance are critical components to the success of wireless service providers, our ability to assist our customers in meeting their goals will ultimately define our success. To that end, we intend to continue to focus on customer service by, for example, reducing cycle time for key functions, such as lease processing and antennae and line installations. Accordingly, we have established a team dedicated to exploring and leveraging customer-driven process improvement capabilities. This establishes another connection point with our customers, sharing operational processes and outcomes, and provides us valuable input and relationship enhancing opportunities. We believe that this effort should enable us to improve revenue generation through improved speed, accuracy and quality.

•

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

•

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

The Exchange Offer

All capitalized terms used, but not defined in, this section shall have the respective meanings set forth under “Description of Notes” beginning on page 31 of this prospectus.

Summary of Terms of the Exchange Offer


Background	We sold the old notes on November 18, 2003 in an unregistered private placement to a group of investment banks as initial purchasers. In connection with that private placement, we entered into a registration rights agreement in which we agreed to deliver this prospectus to you and to make an exchange offer for the old notes.

The Exchange Offer	We are offering to exchange up to $400.0 million aggregate principal amount of our new notes, which have been registered under the Securities Act, for up to $400.0 million aggregate principal amount of our old notes. You may tender old notes only in integral multiples of $1,000 principal amount.

Resale of New Notes	Based on interpretive letters of the SEC staff to third parties, we believe that you may resell and transfer the new notes issued pursuant to the exchange offer in exchange for old notes without compliance with the registration and prospectus delivery requirements of the Securities Act, if:

	•	you are acquiring the new notes in the ordinary course of your business,

	•	you have no arrangement or understanding with any person to participate in the distribution of the new notes, and

	•	you are not our affiliate as defined under Rule 405 of the Securities Act.

	If you fail to satisfy any of these conditions, you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.

	Broker-dealers that acquired old notes directly from us, but not as a result of market-making activities or other trading activities, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes. See “Plan of Distribution” on page 86 of this prospectus.

	Each broker-dealer that receives new notes for its own account pursuant to the exchange offer in exchange for old notes that it acquired as a result of market-making or other trading activities must deliver a prospectus in connection with any resale of the new notes and provide us with a signed acknowledgement of this obligation.

Consequences If You Do Not Exchange Your Old Notes	Old notes that are not tendered in the exchange offer or are not accepted for exchange will continue to bear legends restricting their transfer. You will not be able to offer or sell the old notes unless:

	•	an exemption from the requirements of the Securities Act is available to you,


	•	we register the resale of old notes under the Securities Act, or

	•	the transaction requires neither an exemption from nor registration under the requirements of the Securities Act.

	After the completion of the exchange offer, we will no longer have an obligation to register the old notes, except in limited circumstances.

Expiration Date	5:00 p.m., New York City time, on May 17, 2004, unless we extend the exchange offer.

Conditions to the Exchange Offer	The exchange offer is subject to limited, customary conditions, which we may waive.

Procedures for Tendering Old Notes	If you wish to accept the exchange offer, you must deliver to the exchange agent:

	•	either a completed and signed letter of transmittal or, for old notes tendered electronically, an agent’s message from The Depository Trust Company, which we refer to as DTC, Euroclear or Clearstream stating that the tendering participant agrees to be bound by the letter of transmittal and the terms of the exchange offer,

	•	your old notes, either by tendering them in physical form or by timely confirmation of book-entry transfer through DTC, Euroclear or Clearstream, and

	•	all other documents required by the letter of transmittal.

	These actions must be completed before the expiration of the exchange offer.

	If you hold old notes through DTC, Euroclear or Clearstream, you must comply with their standard procedures for electronic tenders, by which you will agree to be bound by the letter of transmittal.

	By signing, or by agreeing to be bound by, the letter of transmittal, you will be representing to us that:

	•	you will be acquiring the new notes in the ordinary course of your business,

	•	you have no arrangement or understanding with any person to participate in the distribution of the new notes, and

	•	you are not our affiliate as defined under Rule 405 of the Securities Act.

	See “The Exchange Offer—Procedures for Tendering” on page 26 of this prospectus.

Guaranteed Delivery Procedures for Tendering Old Notes	If you cannot meet the expiration deadline or you cannot deliver your old notes, the letter of transmittal or any other documentation to comply with the applicable procedures under DTC, Euroclear or Clearstream standard operating procedures for electronic tenders in a timely fashion, you may tender your notes according to the guaranteed delivery procedures set forth under “The Exchange Offer—Guaranteed Delivery Procedures” on page 28 of this prospectus.


Special Procedures for Beneficial Holders		If you beneficially own old notes that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and you wish to tender in the exchange offer, you should contact that registered holder promptly and instruct that person to tender on your behalf. If you wish to tender in the exchange offer on your own behalf, you must, prior to completing and executing the letter of transmittal and delivering your old notes, either arrange to have the old notes registered in your name or obtain a properly completed bond power from the registered holder. The transfer of registered ownership may take considerable time.

Withdrawal Rights		You may withdraw your tender of old notes at any time before the exchange offer expires.

Tax Consequences		The exchange pursuant to the exchange offer generally will not be a taxable event for U.S. federal income tax purposes. See “Certain United States Federal Income Tax Consequences” on page 81 of this prospectus.

Use of Proceeds		We will not receive any proceeds from the exchange or the issuance of the new notes.

Exchange Agent		The Bank of New York is serving as exchange agent in connection with the exchange offer. The address and telephone number of the exchange agent are set forth under “Exchange Agent” on page 87 of this prospectus.

Summary Description of the New Notes

The form and terms of the new notes are the same as the form and terms of the old notes, except that:

•

the new notes will be registered under the Securities Act and therefore will not bear legends restricting their transfer, and

•

specified rights under the registration rights agreement, including the provisions providing for registration rights and the payment of additional interest in specified circumstances, will be limited or eliminated.

The new notes will evidence the same debt as the old notes and will rank equally with the old notes. The same indenture will govern both the old notes and the new notes. We refer to the old notes and the new notes together as the “notes.”


Issuer	American Towers, Inc., a Delaware corporation (“ATI”).

New Notes Offered	$400,000,000 principal amount of 7.25% Senior Subordinated Notes due 2011.

Maturity Date	December 1, 2011.

Interest Payments	7.25% per annum, payable on June 1 and December 1 of each year, beginning June 1, 2004.

Ranking	The notes are general, unsecured obligations of ATI and will rank junior in right of payment to all of its existing and future senior indebtedness and structurally senior in right of payment to all existing and future indebtedness of its parent.

	As of December 31, 2003, after giving effect to the “as adjusted” transactions described under “Capitalization” on page 22 of this prospectus, the notes would rank:

	•	structurally senior to approximately $1.7 billion of indebtedness of American Tower Corporation.



Guarantees		The notes are jointly and severally guaranteed on a senior subordinated basis by certain of ATI’s sister companies, which are wholly owned by ATI’s parent, and substantially all of ATI’s and the sister companies’ wholly owned domestic subsidiaries (together, the “Group Guarantors”) and by ATI’s parent corporation, American Tower Corporation.

		As of December 31, 2003, after giving effect to the “as adjusted” transactions described under “Capitalization” on page 22 of this prospectus, the guarantees of the Group Guarantors of the notes would rank: • pari passu with their guarantees of approximately $468.4 million of ATI’s outstanding 12.25% senior subordinated discount notes ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million); • subordinate to approximately $0.7 billion of indebtedness under the credit facilities and other senior indebtedness of ATI and certain non-guarantor subsidiaries; and • structurally senior to approximately $1.7 billion of indebtedness of American Tower Corporation. The guarantee of American Tower Corporation of the notes would rank: • pari passu to its guarantee of approximately $468.4 million of ATI’s outstanding 12.25% senior subordinated discount notes ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million); and • subordinate to approximately $1.7 billion of indebtedness of American Tower Corporation, its guarantee of approximately $0.7 billion under the credit facilities and other senior indebtedness of ATI and certain non-guarantor subsidiaries.

Optional Redemption		We may redeem any of the notes at any time on or after December 1, 2007, in whole or in part, in cash at the redemption prices described in this prospectus.

		We may also redeem up to 35% of the original principal amount of the Notes at any time prior to December 1, 2006 at a price equal to 107.25% of the principal amount of the notes plus accrued and unpaid interest thereon and additional interest, if any, with the net cash proceeds of certain public equity offerings within 60 days after the closing of any such offering.

		See “Description of Notes—Optional Redemption” on page 36 of this prospectus.

Change of Control Offer		If we undergo a change of control, we may be required to make an offer to purchase each holder’s notes at a price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest and additional interest, if any, up to but excluding the repurchase date.



Certain Covenants	The indenture governing the notes contains covenants that, among other things, limit the ability of ATI, ATI’s restricted subsidiaries, American Tower International, Inc. and American Tower LLC (which, together with American Tower International, Inc., we refer to as the “sister guarantors”) and their respective restricted subsidiaries to:

	•	incur or guarantee additional indebtedness;

	•	create liens;

	•	pay dividends or make other equity distributions;

	•	enter into agreements restricting the restricted subsidiaries’ ability to pay dividends;

	•	purchase or redeem capital stock;

	•	make investments;

	•	sell assets or consolidate or merge with or into other companies; and

	•	engage in transactions with affiliates.

	These limitations are subject to a number of important qualifications and exceptions. See “Description of Notes—Certain Covenants” on page 40 of this prospectus.

(1)

As of January 1, 2002, we adopted the provisions of SFAS No. 142 “Goodwill and Other Intangible Assets” (SFAS No. 142). Accordingly, we ceased amortizing goodwill on January 1, 2002. The statements of operations for all periods presented, except for the years ended December 31, 2002 and 2003, include goodwill amortization. The adoption of SFAS No. 142 reduced amortization expense in continuing operations by approximately $67.6 million for the years ended December 31, 2003 and 2002.

(2)

We computed basic and diluted loss per common share from continuing operations before cumulative effect of change in accounting principle using the weighted average number of shares outstanding during each period presented. We have excluded shares issuable upon exercise of options and other common stock equivalents from these computations, as their effect is anti-dilutive.

(3)

For purposes of calculating this ratio, “earnings” consists of loss from continuing operations before income taxes, fixed charges (excluding interest capitalized), minority interest in net earnings of subsidiaries, losses from equity investments and amortization of interest capitalized. “Fixed charges” consist of interest expensed and capitalized, amortization of debt discount and related issuance costs and the component of rental expense associated with operating leases believed by management to be representative of the interest factor thereon. We had a deficiency in earnings to fixed charges in each period as follows (in thousands): 1999—$55,299; 2000—$272,783; 2001—$497,488; 2002—$380,745 and 2003—$301,202.

(4)

Includes, at December 31, 2003, approximately $170.0 million of restricted funds to be held in escrow to pay, repurchase, redeem or retire certain of our outstanding debt. Any balance remaining on June 30, 2004 from the January 2003 12.25% senior subordinated discount notes offering must be used to prepay a portion of the term loans under our credit facilities. Includes, at December 31, 2001 and 2000, approximately $94.1 million and $46.0 million, respectively, of restricted funds required under our credit facilities to be held in escrow through August 2002 to fund scheduled interest payments on our outstanding senior and convertible notes.

(5)

Net debt represents long-term debt, including current portion, less cash and cash equivalents (including restricted cash and investments).

RISK FACTORS

You should consider the following risk factors, in addition to the other information presented in this prospectus and the documents incorporated by reference into this prospectus, in evaluating us, our business and your participation in the exchange offer. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. Any of these risks could seriously harm our business and financial results and cause the value of the notes to decline, which in turn could cause you to lose all or part of your investment.

Risks Related to the Exchange Offer

If you fail to exchange your old notes, they will continue to be restricted securities and may become less liquid.

Old notes that you do not tender or that we do not accept will, following the exchange offer, continue to be restricted securities. You may not offer or sell untendered old notes except pursuant to an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. ATI will issue new notes in exchange for the old notes pursuant to the exchange offer only following the satisfaction of procedures and conditions described elsewhere in this prospectus. These procedures and conditions include timely receipt by the exchange agent of the old notes and of a properly completed and duly executed letter of transmittal.

Because we anticipate that most holders of old notes will elect to exchange their old notes, we expect that the liquidity of the market for any old notes remaining after the completion of the exchange offer may be substantially limited. Any old note tendered and exchanged in the exchange offer will reduce the aggregate principal amount of the old notes outstanding. Following the exchange offer, if you did not tender your old notes you generally will not have any further registration rights and your old notes will continue to be subject to transfer restrictions. Accordingly, the liquidity of the market for any old notes could be adversely affected.

Risks Related to the Notes

Substantial leverage and debt service obligations may adversely affect us.

We have a substantial amount of indebtedness. As of December 31, 2003, we had approximately $3.4 billion of consolidated debt. Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay when due the principal of, interest on, or other amounts due with respect to our indebtedness. Approximately 21% of our outstanding indebtedness bears interest at floating rates. As a result, our interest payment obligations on such indebtedness will increase if interest rates increase.

Our substantial leverage could have significant negative consequences on our financial condition and results of operations, including:

•

impairing our ability 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.

Restrictive covenants in our credit facilities and indentures could adversely affect our business by limiting flexibility.

Our credit facilities and the indentures governing the terms of our other debt securities contain restrictive covenants and, in the case of the credit facilities, requirements that we comply with certain leverage and other financial tests. These limit our ability to take various actions, including incurring additional debt, guaranteeing indebtedness, issuing preferred stock, engaging in various types of transactions, including mergers and sales of assets, and paying dividends and making distributions or other restricted payments, including investments. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisition or other opportunities.

Your right to receive payments on the notes is junior to the existing and future senior indebtedness of ATI.

The notes are subordinated in right of payment to all of ATI’s existing and future senior indebtedness. As of December 31, 2003, after giving effect to the voluntary prepayment of $21.0 million of Term Loan A under the credit facilities, the notes would have been subordinated to approximately $0.7 billion of indebtedness of ATI and certain non-guarantor subsidiaries and pari passu with approximately $468.4 million of ATI’s outstanding 12.25% senior subordinated discount notes ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million). In addition, the guarantees of the notes are subordinated to all existing and future senior indebtedness of the guarantors. As a result, upon any distribution to ATI’s creditors or the creditors of the guarantors in a bankruptcy, liquidation or reorganization or similar proceeding relating to ATI or the guarantors of our or their property, the holders of ATI’s senior debt and the senior debt of the guarantors will be entitled to be paid in full before any payment may be made with respect to the notes or the guarantees.

In addition, all payments on the notes and the guarantees are blocked in the event of a payment default on senior debt and may be blocked for up to 179 of 360 consecutive days in the event of certain non-payment defaults on senior debt.

In the event of a bankruptcy, liquidation or reorganization or similar proceeding relating to ATI or the guarantors, holders of the notes will participate with trade creditors and all other holders of ATI’s and the guarantors’ subordinated indebtedness in the assets remaining after ATI and the subsidiary guarantors have paid all of ATI’s and their respective senior debt. However, because the indenture requires that amounts otherwise payable to holders of the notes in a bankruptcy or similar proceeding be paid to holders of senior debt instead, holders of the notes may receive less, ratably, than holders of trade payables in those proceedings. In any of these cases, ATI and the subsidiary guarantors may not have sufficient funds to pay all of ATI’s and their respective creditors and holders of notes may receive less, ratably, than the holders of senior debt.

Federal and state statutes allow courts, under specific circumstances, to void guarantees and require note holders to return payments received from guarantors.

The notes are guaranteed by ATI’s parent, the sister guarantors and substantially all of ATI’s and the sister guarantors’ wholly owned, domestic subsidiaries. Under federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee could be voided, or claims in respect of a guarantee could be subordinated to all other debts of that guarantor if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee:

•

received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee; and

•

was insolvent or rendered insolvent by reason of such incurrence; or

•

was engaged in a business or transaction for which the guarantor’s remaining assets constituted unreasonably small capital; or

•

intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

In addition, any payment by that guarantor pursuant to its guarantee could be voided and required to be returned to the guarantor, or to a fund for the benefit of the creditors of the guarantor.

The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, a guarantor would be considered insolvent if:

•

the sum of its debts, including contingent liabilities, was greater than the fair saleable value of all of its assets; or

•

the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or

•

it could not pay its debts as they become due.

On the basis of historical financial information, recent operating history and other factors, we believe that each guarantor, after giving effect to its guarantee of these notes, will not be insolvent, will not have unreasonably small capital for the business in which it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

There may be no public market for the new notes, which may significantly impair the liquidity of the new notes.

Prior to the exchange and issuance of the new notes, there has been no public market for the new notes and we cannot assure you as to:

•

the liquidity of any market that may develop;

•

your ability to sell your new notes; or

•

the price at which you would be able to sell your new notes.

If a market were to exist for the new notes, the new notes could trade at prices that may be lower than the principal amount or purchase price, depending on many factors, including prevailing interest rates, the market for similar notes and our financial performance. We do not presently intend to apply for listing of the new notes on any securities exchange.

The initial purchasers in the November 2003 private placement of the old notes in which ATI issued the old notes have advised us that they presently intend to make a market in the new notes. The initial purchasers are not obligated, however, to make a market in these securities, and they may discontinue any such market-making at any time at their sole discretion. In addition, any market-making activity will be subject to the limits imposed by the Securities Act and the Exchange Act. Accordingly, we cannot assure you as to the development or liquidity of any market for the new notes.

Restrictive covenants in our credit facilities and indentures could adversely affect our business by limiting flexibility.

Our credit facilities and the indentures for our 9³/8% senior notes, the 12.25% senior subordinated discount notes, 7.25% senior subordinated notes and 7.50% senior notes contain restrictive covenants and, in the case of the credit facilities, requirements that we comply with certain leverage and other financial tests. These limit our ability to take various actions, including incurring additional debt, guaranteeing indebtedness, issuing preferred stock, engaging in various types of transactions, including mergers and sales of assets, and paying dividends and making distributions or other restricted payments, including investments. These covenants could have an adverse effect on our business by limiting our ability to take advantage of financing, new tower development, merger and acquisition or other opportunities.

We may be unable to repay the notes when due or repurchase the notes when we are required to do so.

At final maturity of the notes or in the event of acceleration of the notes following an event of default, the entire outstanding principal amount of the notes will become due and payable. Upon the occurrence of a change in control (as described herein), we will be required to offer to repurchase all outstanding notes, as well as the 12.25% senior subordinated discount notes, at 101% of the principal amount (or accreted value) of the notes plus accrued and unpaid interest and additional interest, if any, to the date of repurchase. We have similar repurchase obligations under our other outstanding indebtedness. However, it is possible that we will not have sufficient funds at maturity, upon acceleration or at the time of the change in control to make the required repurchase of notes.

Moreover, the credit facilities prohibit us from redeeming or repurchasing any of the notes for cash. As a result, we would not be able to make any of the required payments on the notes described in the prior paragraph without obtaining the consent of the lenders under the credit facilities with respect to such payment. If we are unable to make the required payments or repurchases of the notes, it would constitute an event of default under the notes offered hereby and, as a result, under the credit facilities.

Risks Related to Our Business

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

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

•

consumer demand for wireless services;

•

the financial condition of wireless service providers;

•

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

•

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

•

governmental licensing of broadcast rights;

•

mergers or consolidations among wireless service providers;

•

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

•

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

•

zoning, environmental, health and other government regulations; and

•

technological changes.

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

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

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

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

Significant consolidation among our wireless service provider customers, such as the recently announced transaction between Cingular Wireless and AT&T Wireless, may result in reduced capital expenditures in the aggregate because the existing networks of many wireless carriers overlap, as do their expansion plans. Similar consequences might occur if wireless service providers engage in extensive sharing or roaming or resale arrangements as an alternative to leasing our antennae space. In January 2003, the Federal Communications Commission (FCC) eliminated its spectrum cap, which prohibited wireless carriers from owning more than 45 MHz of spectrum in any given geographical area. The FCC has also eliminated the cross-interest rule for metropolitan areas, which limited an entity’s ability to own interests in multiple cellular licenses in an overlapping geographical service area. Also, in May 2003, the FCC adopted new rules authorizing wireless radio services holding exclusive licenses to freely lease unused spectrum. Some wireless carriers may be encouraged to consolidate with each other as a result of these regulatory changes 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. Many wireless service providers operate with substantial leverage. 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. In addition, Iusacell Celular, which is our largest customer in Mexico and accounted for approximately 4.7% of our total revenues for the year ended December 31, 2003 and approximately 3.7% for the year ended December 31, 2002, is currently in default under its debt obligations. If one or more of our major customers experience financial difficulties or if Iusacell Celular files for bankruptcy, it could result in uncollectible accounts receivable and our loss of significant customers and anticipated lease revenues.

Our foreign operations are subject to expropriation risk, governmental regulation, funds inaccessibility and foreign exchange exposure.

Our expansion in Mexico and Brazil, and any other possible foreign operations in the future, could result in adverse financial consequences and operational problems not experienced in the United States. We have loaned $119.8 million (undiscounted) to a Mexican company, own or have the economic rights to over 1,800 towers in Mexico, including approximately 200 broadcast towers (after giving effect to pending transactions) and, subject to certain rejection rights, are contractually committed to construct up to approximately 400 additional towers in that country over the next three years. We also own or have acquired the rights to approximately 425 communications towers in Brazil and are, subject to certain rejection rights, contractually committed to construct up to 350 additional towers in that country over the next three years. The actual number of sites constructed will vary depending on the build out plans of the applicable carrier. We may, if economic and capital market conditions permit, also engage in comparable transactions in other countries in the future. Among the risks of foreign operations are governmental expropriation and regulation, the credit quality of our customers, 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.

A substantial portion of our revenues is derived from a small number of customers.

A substantial portion of our total operating revenues is derived from a small number of customers. Approximately 61.5% of our revenues for the year ended December 31, 2003 were derived from eight customers. Our largest domestic customer is Verizon Wireless, which represented approximately 12.3% of our total revenues for the year ended December 31, 2003. If the recently announced transaction between Cingular Wireless and AT&T Wireless had occurred as of January 1, 2003, however, the combined revenues would have represented approximately 15.0% of our total revenues for the year ended December 31, 2003. Our largest international customer is a group of companies affiliated with Azteca Holdings, S.A. de C.V., including TV Azteca, Unefon and (due to its acquisition in 2003 of Iusacell by Movil Access, an affiliate of Azteca Holdings) Iusacell Celular. Iusacell Celular, Unefon and their affiliates collectively represented approximately 7.5% of our total revenues for the year ended December 31, 2003. In addition, we received $14.2 million in interest income, net, for the year ended December 31, 2003 from TV Azteca. If any of these customers were unwilling or unable to perform their obligations under our agreements with them, our revenues, results of operations, and financial condition could be adversely affected.

In the ordinary course of our business, we also sometimes experience disputes with our customers, generally regarding the interpretation of terms in our agreements. Although historically we have resolved most of these disputes in a manner that did not have a material adverse effect on our company or our customer relationships, these disputes could lead to a termination of our agreements with customers or a material modification of the terms of those agreements, either of which could have a material adverse effect on our business, results of operations and financial condition. If we are forced to resolve any of these disputes through litigation, our relationship with the applicable customer could be terminated or damaged, which could lead to decreased revenues or increased costs, resulting in a corresponding adverse effect on our operating results.

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

The development and implementation of new technologies designed to enhance the efficiency of wireless networks could reduce the use and need for tower-based wireless services transmission and reception and have the effect of decreasing demand for antenna space. Examples of such technologies include technologies that enhance spectral capacity, such as lower-rate vocoders, which can increase the capacity at existing sites and 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 broadcast services transmission and reception. For example, the growth in delivery of video services by direct broadcast satellites could adversely affect demand for our antenna space. The development and implementation of any of these and similar technologies to any significant degree could have an adverse effect on our operations.

We could have liability under environmental laws.

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

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

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

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

Our industry is highly competitive, and our customers have numerous alternatives for leasing antenna space. Some of our competitors are larger and have greater financial resources than we do, while other competitors are in weak financial condition or may have lower return on investment criteria than we do. Competitive pricing pressures for tenants on towers from these competitors could adversely affect our lease rates and services income.

In addition, if we lose customers due to pricing, we may not be able to find new customers, leading to an accompanying adverse effect on our profitability. Increasing competition could also make the acquisition of high quality tower assets more costly.

Our competition includes:

•

national tower companies;

•

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

•

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

•

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

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

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

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

The bankruptcy proceeding of our Verestar subsidiary exposes us to risks and uncertainties.

Our wholly owned subsidiary, Verestar, Inc., filed for protection under Chapter 11 of the federal bankruptcy laws on December 22, 2003. Verestar was reported as a discontinued operation in December 2002 for financial statement purposes, and, as of the date of the bankruptcy filing, was deconsolidated for financial statement purposes.

If Verestar fails to honor certain of its contractual obligations because of its bankruptcy filing or otherwise, claims may be made against us for breaches by Verestar of those contracts as to which we are primarily or secondarily liable as a guarantor, which we do not expect will exceed $10.0 million. In addition, Verestar’s bankruptcy estate may bring certain claims against us or seek to hold us liable for certain transfers made by Verestar to us and/or for Verestar’s obligations to creditors under various equitable theories recognized under bankruptcy law. The outcome of complex litigation (including those claims which may be asserted against us by Verestar’s bankruptcy estate) cannot be predicted with certainty and is dependent upon many factors beyond our control. Finally, we will incur additional costs in connection with out involvement in the reorganization or liquidation of Verestar’s business.

USE OF PROCEEDS

In consideration for issuing the new notes, we will receive old notes from you in like principal amount. The old notes surrendered in exchange for the new notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the new notes will not result in any change in our indebtedness.

THE EXCHANGE OFFER

Purpose and Effect of Exchange Offer

We sold the old notes on November 18, 2003 in an unregistered private placement to a group of investment banks as the initial purchasers. As part of that offering, we entered into a registration rights agreement with the initial purchasers. Under the registration rights agreement, we agreed to file this registration statement to offer to exchange the old notes for new notes in an offering registered under the Securities Act. This exchange offering satisfies that obligation. We also agreed to perform other obligations under that registration rights agreement. See “Description of the Notes—Registration Rights; Additional Interest.”

By participating in the exchange offer, holders of the old notes will receive new notes that are freely tradable and not subject to restrictions on transfer, subject to the exceptions described under “Resale of New Notes” immediately below. In addition, holders of new notes generally will not be entitled to additional interest.

Resale of New Notes

We believe that the new notes issued in exchange for the old notes may be offered for resale, resold and otherwise transferred by any new note holder without compliance with the registration and prospectus delivery provisions of the Securities Act if the conditions set forth below are met. We base this belief solely on interpretations of the federal securities laws by the SEC set forth in several no-action letters issued to third parties unrelated to us. A no-action letter is a letter from the SEC responding to a request for its views as to whether a particular matter complies with the federal securities laws or whether the SEC would refer the matter to the SEC’s enforcement division for action. We have not obtained, and do not intend to obtain, our own no-action letter from the SEC regarding the resale of the new notes. Instead, holders will be relying on the no-action letters that the SEC has issued to third parties in circumstances that we believe are similar to ours. Based on these no-action letters, the following conditions must be met:

•

the holder must acquire the new notes in the ordinary course of its business,

•

the holder must have no arrangements or understanding with any person to participate in the distribution of the new notes within the meaning of the Securities Act, and

•

the holder must not be an “affiliate,” as defined in Rule 405 of the Securities Act, of ours.

Each holder of old notes that wishes to exchange old notes for new notes in the exchange offer must represent to us that it satisfies all of above listed conditions. Any holder who tenders in the exchange offer who does not satisfy all of the above listed conditions:

•

cannot rely on the position of the SEC set forth in the no-action letters referred to above, and

•

must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.

The SEC considers broker-dealers that acquired old notes directly from us, but not as a result of market-making activities or other trading activities, to be making a distribution of the new notes if they participate in the exchange offer. Consequently, these holders must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a resale of the new notes.

Each broker-dealer that receives new notes for its own account in exchange for old notes acquired by that broker-dealer as a result of market-making activities or other trading activities must deliver a prospectus in connection with a resale of the new notes and provide us with a signed acknowledgement of this obligation. A broker-dealer may use this prospectus, as amended or supplemented from time to time, in connection with resales of new notes received in exchange for old notes where the broker-dealer acquired the old notes as a result of market-making activities or other trading activities. The letter of transmittal states that by acknowledging and delivering a prospectus, a broker-dealer will not be considered to admit that it is an “underwriter” within the meaning of the

Securities Act. We have agreed that for a period of 180 days after the expiration date of the exchange offer, we will make this prospectus available to broker-dealers for use in connection with any resale of the new notes.

Except as described in the prior paragraph, holders may not use this prospectus for an offer to resell, a resale or other retransfer of new notes. We are not making this exchange offer to, nor will we accept tenders for exchange from, holders of old notes in any jurisdiction in which the exchange offer or the acceptance of it would not be in compliance with the securities or blue sky laws of that jurisdiction.

Terms of the Exchange

Upon the terms and subject to the conditions set forth in this prospectus and the accompanying letter of transmittal, which we refer to together in this prospectus as the “exchange offer,” we will accept any and all old notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the expiration date. The date of acceptance for exchange of the old notes, and completion of the exchange offer, is the exchange date, which will be the first business day following the expiration date, unless extended as described in this prospectus. We will issue, on or promptly after the exchange date, an aggregate principal amount of up to $400.0 million of new notes for a like principal amount of outstanding old notes tendered and accepted in connection with the exchange offer. The new notes issued in connection with the exchange offer will be delivered as soon as practicable following the exchange date. Holders may tender some or all of their old notes in connection with the exchange offer, but only in integral multiples of $1,000. The exchange offer is not conditioned upon any minimum amount of old notes being tendered for exchange.

The terms of the new notes are identical in all material respects to the terms of the old notes, except that:

•

we have registered the new notes under the Securities Act and therefore these notes will not bear legends restricting their transfer, and

•

specified rights under the registration rights agreement, including the provisions providing for payment of additional interest in specified circumstances relating to the exchange offer, will be limited or eliminated.

The new notes will evidence the same debt as the old notes. The new notes will be issued under the same indenture and entitled to the same benefits under that indenture as the old notes being exchanged. As of the date of this prospectus, $400.0 million in aggregate principal amount of the old notes were outstanding. Old notes accepted for exchange will be retired and cancelled and not reissued.

In connection with the issuance of the old notes, we arranged for the old notes originally purchased by qualified institutional buyers to be issued and transferable in book-entry form through the facilities of DTC, acting as depositary. Except as described under “Book-Entry Transfer,” we will issue the new notes in the form of a global note registered in the name of DTC or its nominee, and each beneficial owner’s interest in it will be transferable in book-entry form through DTC.

Holders of old notes do not have any appraisal or dissenters’ rights in connection with the exchange offer. We intend to conduct the exchange offer in accordance with the applicable requirements of the Exchange Act and the rules and regulations of the SEC.

We will be considered to have accepted validly tendered old notes if and when we have given oral or written notice to that effect to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the new notes from us.

If we do not accept any tendered old notes for exchange because of an invalid tender, the occurrence of the other events described in this prospectus or otherwise, we will return these old notes, without expense, to the tendering holder as quickly as possible after the expiration date of the exchange offer.

Holders who tender old notes will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes on exchange of old notes in connection with the exchange

offer. We will pay all charges and expenses, other than the applicable taxes described in the section “Fees and Expenses,” in connection with the exchange offer.

If we successfully complete the exchange offer, any old notes which holders do not tender or which we do not accept in the exchange offer will remain outstanding and continue to accrue interest. The holders of old notes after the exchange offer in general will not have further rights under the registration rights agreement, including registration rights and any rights to additional interest. Holders wishing to transfer the old notes would have to rely on exemptions from the registration requirements of the Securities Act.

Expiration Date; Extensions; Amendments

The expiration date for the exchange offer is 5:00 p.m., New York City time, on May 17, 2004. We may extend this expiration date in our sole discretion, but in no event to a date later than May 27, 2004, unless otherwise required by applicable law. If we so extend the expiration date, the term “expiration date” shall mean the latest date and time to which we extend the exchange offer.

We reserve the right, in our sole discretion:

•

to delay accepting any old notes,

•

to extend the exchange offer,

•

to terminate the exchange offer if, in our sole judgment, any of the conditions described below shall not have been satisfied, or

•

to amend the terms of the exchange offer in any manner.

We will give oral or written notice of any delay, extension or termination to the exchange agent. In addition, we will give, as promptly as practicable, oral or written notice regarding any delay in acceptance, extension or termination of the offer to the registered holders of old notes. If we amend the exchange offer in a manner that we determine to constitute a material change, or if we waive a material condition, we will promptly disclose the amendment or waiver in a manner reasonably calculated to inform the holders of old notes of the amendment, and extend the offer if required by law.

Without limiting the manner in which we may choose to make public announcements of any delay in acceptance, extension, termination, amendment or waiver regarding the exchange offer, we shall have no obligation to publish, advertise, or otherwise communicate any public announcement, other than by making a timely release to a financial news service.

Interest on the New Notes

Interest on the new notes will accrue at the rate of 7.25% per annum on the principal amount, payable semiannually on June 1 and December 1, beginning June 1, 2004. Interest on the new notes will accrue from the date of issuance of the old notes or the date of the last periodic payment of interest on such old notes, whichever is later.

Conditions to the Exchange Offer

Despite any other term of the exchange offer, we will not be required to accept for exchange, or exchange new notes for, any old notes and we may terminate the exchange offer as provided in this prospectus before the acceptance of the old notes, if:

•

the exchange offer, or the making of any exchange by a holder, violates, in our good faith determination, any applicable law, rule or regulation or any applicable interpretation of the staff of the SEC,

•

any action or proceeding shall have been instituted or threatened with respect to the exchange offer which, in our reasonable judgment, would impair our ability to proceed with the exchange offer, or

•

we have not obtained any governmental approval which we, in our sole discretion, exercised reasonably, consider necessary for the completion of the exchange offer as contemplated by this prospectus.

The conditions listed above are for our sole benefit and we may assert them regardless of the circumstances giving rise to any of these conditions. We may waive these conditions in our sole discretion in whole or in part at any time. A failure on our part to exercise any of the above rights shall not constitute a waiver of that right, and that right shall be considered an ongoing right which we may assert at any time and from time to time.

If we determine in our sole discretion, exercised reasonably, that any of the events listed above has occurred, we may, subject to applicable law:

•

refuse to accept any old notes and return all tendered old notes to the tendering holders,

•

extend the exchange offer and retain all old notes tendered before the expiration of the exchange offer, subject, however, to the rights of holders to withdraw these old notes, or

•

waive unsatisfied conditions relating to the exchange offer and accept all properly tendered old notes that have not been withdrawn.

Any determination by us concerning the above events will be final and binding.

In addition, we reserve the right in our sole discretion, exercised reasonably, to:

•

purchase or make offers for any old notes that remain outstanding subsequent to the expiration date, and

•

to the extent permitted by applicable law, purchase old notes in the open market, in privately negotiated transactions or otherwise.

The terms of any purchases or offers may differ from the terms of the exchange offer. Those purchases would require the consent of the lenders under our credit facilities.

Procedures for Tendering

Except in limited circumstances, only a Euroclear participant, Clearstream participant or DTC participant listed on a DTC securities position listing with respect to the old notes may tender old notes in the exchange offer. To tender old notes in the exchange offer:

•

holders of old notes that are DTC participants may follow the procedures for book-entry transfer as set forth under “Book-Entry Transfer” and in the letter of transmittal; or

•

Euroclear participants and Clearstream participants on behalf of the beneficial owners of old notes are required to use book-entry transfer pursuant to the standard operating procedures of Euroclear or Clearstream. These procedures include the transmission of a computer-generated message to Euroclear or Clearstream in lieu of a letter of transmittal. See the description of “agent’s message” under “Book-Entry Transfer.”

In addition, you must comply with one of the following:

•

the exchange agent must receive, before expiration of the exchange offer, a timely confirmation of book-entry transfer of old notes into the exchange agent’s account at DTC, Euroclear or Clearstream according to their respective standard operating procedures for electronic tenders and a properly transmitted agent’s message as described below, or

•

the exchange agent must receive any corresponding certificate or certificates representing old notes along with the letter of transmittal, or

•

the holder must comply with the guaranteed delivery procedures described below.

The tender by a holder of old notes will constitute an agreement between the holder and us in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. If less than all the old notes held by a holder are tendered, the tendering holder should fill in the amount of old notes being

tendered in the specified box on the letter of transmittal. The entire amount of old notes delivered or transferred to the exchange agent will be deemed to have been tendered unless otherwise indicated.

The method of delivery of old notes, the letter of transmittal and all other required documents or transmission of an agent’s message, as described under “Book-Entry Transfer,” to the exchange agent is at the election and risk of the holder. Instead of delivery by mail, we recommend that holders use an overnight or hand delivery service. In all cases, sufficient time should be allowed to assure timely delivery to the exchange agent prior to the expiration of the exchange offer. No letter of transmittal or old notes should be sent to us, DTC, Euroclear or Clearstream. Delivery of documents to DTC, Euroclear or Clearstream in accordance with their respective procedures will not constitute delivery to the exchange agent.

Any beneficial holder whose old notes are registered in the name of his or its broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact the registered holder promptly and instruct it to tender on the beneficial holder’s behalf. If any beneficial holder wishes to tender on its own behalf, it must, prior to completing and executing the letter of transmittal and delivering its old notes, either:

•

make appropriate arrangements to register ownership of the old notes in its name, or

•

obtain a properly completed bond power from the registered holder.

The transfer of record ownership may take considerable time and may not be completed prior to the expiration date.

Signatures on a letter of transmittal or a notice of withdrawal, as described in “Withdrawal of Tenders,” must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or an “eligible guarantor institution”, within the meaning of Rule 17Ad-15 under the Exchange Act, which we refer to in this prospectus as an “eligible institution”, unless the old notes are tendered:

•

by a registered holder who has not completed the box entitled “Special Issuance Instructions” or “Special Delivery Instructions” on the letter of transmittal; or

•

for the account of an eligible institution.

If the letter of transmittal is signed by a person other than the registered holder of any old notes listed therein, the old notes must be endorsed or accompanied by appropriate bond powers which authorize the person to tender the old notes on behalf of the registered holder, in either case signed as the name of the registered holder or holders appears on the old notes. If the letter of transmittal or any old notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, those persons should so indicate when signing and, unless waived by us, evidence satisfactory to us of their authority to so act must be submitted with the letter of transmittal.

We will determine in our sole discretion, exercised reasonably, all questions as to the validity, form, eligibility, including time of receipt, and acceptance and withdrawal of tendered old notes. We reserve the absolute right to reasonably reject any and all old notes not properly tendered or any old notes whose acceptance by us would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defects, irregularities or conditions of tender as to any particular old notes either before or after the expiration date. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, holders must cure any defects or irregularities in connection with tenders of old notes within a period we will determine. Although we intend to request the exchange agent to notify holders of defects or irregularities relating to tenders of old notes, neither we, the exchange agent nor any other person will have any duty or incur any liability for failure to give this notification. We will not consider tenders of old notes to have been made until these defects or irregularities have been cured or waived. The exchange agent will return any old notes that are not properly tendered and as to which the

defects or irregularities have not been cured or waived to the tendering holders, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration date.

In addition, we reserve the right, as set forth under the caption “Conditions to the Exchange Offer,” to terminate the exchange offer.

By tendering, each holder represents to us, among other things, that:

•

the holder acquired new notes pursuant to the exchange offer in the ordinary course of its business,

•

the holder has no arrangement or understanding with any person to participate in the distribution of the new notes within the meaning of the Securities Act, and

•

the holder is not our “affiliate,” as defined in Rule 405 under the Securities Act.

If the holder is a broker-dealer that will receive new notes for its own account in exchange for old notes acquired by the broker-dealer as a result of market-making activities or other trading activities, the holder must acknowledge that it will deliver a prospectus in connection with any resale of the new notes.

Book-Entry Transfer

We understand that the exchange agent will make a request promptly after the date of this prospectus to establish accounts with respect to the old notes at DTC, Euroclear and Clearstream for the purpose of facilitating the exchange offer. Any financial institution that is a participant in DTC’s system may make book-entry delivery of old notes by causing DTC to transfer the old notes into the exchange agent’s DTC account in accordance with DTC’s Automated Tender Offer Program procedures for the transfer. Any participant in Euroclear or Clearstream may make book-entry delivery of old notes by causing Euroclear or Clearstream to transfer the old notes into the exchange agent’s account in accordance with established Euroclear or Clearstream procedures for transfer. The exchange of new notes for tendered old notes will only be made after a timely confirmation of a book-entry transfer of the old notes into the exchange agent’s account and timely receipt by the exchange agent of an agent’s message.

The term “agent’s message” means a message, transmitted by DTC, Euroclear or Clearstream, and received by the exchange agent and forming part of the confirmation of a book-entry transfer, which states that DTC, Euroclear or Clearstream has received an express acknowledgment from a participant tendering old notes that the participant has received an appropriate letter of transmittal and agrees to be bound by the terms of the letter of transmittal, and that we may enforce the agreement against the participant. Delivery of an agent’s message will also constitute an acknowledgment from the tendering DTC, Euroclear or Clearstream participant that the representations contained in the letter of transmittal and described under “Resale of New Notes” are true and correct.

Guaranteed Delivery Procedures

The following guaranteed delivery procedures are intended for holders who wish to tender their old notes but:

•

their old notes are not immediately available,

•

the holders cannot deliver their old notes, the letter of transmittal, or any other required documents to the exchange agent prior to the expiration date, or

•

the holders cannot complete the procedure under the respective DTC, Euroclear or Clearstream standard operating procedures for electronic tenders before expiration of the exchange offer.

The conditions that must be met to tender old notes through the guaranteed delivery procedures are as follows:

•

the tender must be made through an eligible institution,

•

before expiration of the exchange offer, the exchange agent must receive from the eligible institution either a properly completed and duly executed notice of guaranteed delivery in the form accompanying this prospectus, by facsimile transmission, mail or hand delivery, or a properly transmitted agent’s message in lieu of notice of guaranteed delivery:

•

setting forth the name and address of the holder, the certificate number or numbers of the old notes tendered and the principal amount of old notes tendered;

•

stating that the tender offer is being made by guaranteed delivery; and

•

guaranteeing that, within three New York Stock Exchange trading days after expiration of the exchange offer, the letter of transmittal, or facsimile of the letter of transmittal, together with the old notes tendered or a book-entry confirmation, and any other documents required by the letter of transmittal will be deposited by the eligible institution with the exchange agent; and

•

the exchange agent must receive the properly completed and executed letter of transmittal, or facsimile of the letter of transmittal, as well as all tendered old notes in proper form for transfer or a book-entry confirmation, and any other documents required by the letter of transmittal, within three New York Stock Exchange trading days after expiration of the exchange offer.

Upon request to the exchange agent, a notice of guaranteed delivery will be sent to holders who wish to tender their old notes according to the guaranteed delivery procedures set forth above.

Withdrawal of Tenders

Your tender of old notes pursuant to the exchange offer is irrevocable except as otherwise provided in this section. You may withdraw tenders of old notes at any time prior to 5:00 p.m., New York City time, on the expiration date.

For a withdrawal to be effective:

•

the exchange agent must receive a written notice, which may be by facsimile transmission or letter, of withdrawal at the address set forth below under “Exchange Agent,” or

•

for DTC, Euroclear or Clearstream participants, holders must comply with their respective standard operating procedures for electronic tenders and the exchange agent must receive an electronic notice of withdrawal from DTC, Euroclear or Clearstream.

Any notice of withdrawal must:

•

specify the name of the person who tendered the old notes to be withdrawn,

•

identify the old notes to be withdrawn, including the certificate number or numbers and principal amount of the old notes to be withdrawn,

•

be signed by the person who tendered the old notes in the same manner as the original signature on the letter of transmittal, including any required signature guarantees, and

•

specify the name in which the old notes are to be re-registered, if different from that of the withdrawing holder.

If old notes have been tendered pursuant to the procedure for book-entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC, Euroclear or Clearstream to be credited with the withdrawn old notes and otherwise comply with the procedures of the applicable facility. We will determine in our sole discretion, exercised reasonably, all questions as to the validity, form and eligibility, including time of receipt, for the withdrawal notices, and our determination will be final and binding on all parties. Any old notes so withdrawn will be deemed not to have been validly tendered for purposes of the exchange offer and no new notes will be issued with respect to them unless the old notes so withdrawn are validly retendered. Any old notes

which have been tendered but which are not accepted for exchange will be returned to the holder without cost to the holder as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. Properly withdrawn old notes may be re-tendered by following the procedures described under “Procedures for Tendering” at any time prior to the expiration date.

Fees and Expenses

We will not make any payments to brokers, dealers or other persons soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and its related reasonable out-of-pocket expenses, including accounting and legal fees. We may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this prospectus, letters of transmittal and related documents to the beneficial owners of the old notes and in handling or forwarding tenders for exchange.

Holders who tender their old notes for exchange will not be obligated to pay any transfer taxes. If, however:

•

new notes are to be delivered to, or issued in the name of, any person other than the registered holder of the old notes tendered, or

•

tendered old notes are registered in the name of any person other than the person signing the letter of transmittal, or

•

a transfer tax is imposed for any reason other than the exchange of old notes in connection with the exchange offer,

then the tendering holder must pay the amount of any transfer taxes due, whether imposed on the registered holder or any other persons. If the tendering holder does not submit satisfactory evidence of payment of these taxes or exemption from them with the letter of transmittal, the amount of these transfer taxes will be billed directly to the tendering holder.

Consequences of Failures to Properly Tender Old Notes in the Exchange

We will issue the new notes in exchange for old notes under the exchange offer only after timely receipt by the exchange agent of the old notes, a properly completed and duly executed letter of transmittal and all other required documents. Therefore, holders of the old notes desiring to tender old notes in exchange for new notes should allow sufficient time to ensure timely delivery. We are under no duty to give notification of defects or irregularities of tenders of old notes for exchange. Old notes that are not tendered or that are tendered but not accepted by us will, following completion of the exchange offer, continue to be subject to the existing restrictions upon transfer under the Securities Act. Upon completion of the exchange offer, specified rights under the registration rights agreement, including registration rights and any right to additional interest, will be either limited or eliminated.

Participation in the exchange offer is voluntary. In the event the exchange offer is completed, we will not be required to register the remaining old notes. Remaining old notes will continue to be subject to the following restrictions on transfer:

•

holders may resell old notes only if we register the old notes under the Securities Act, if an exemption from registration is available, or if the transaction requires neither registration under nor an exemption from the requirements of the Securities Act, and

•

the remaining old notes will bear a legend restricting transfer in the absence of registration or an exemption.

We do not currently anticipate that we will register the remaining old notes under the Securities Act. To the extent that old notes are tendered and accepted in connection with the exchange offer, any trading market for remaining old notes could be adversely affected.

DESCRIPTION OF NOTES

You can find the definitions of certain terms used in this description under the subheading “Certain Definitions” on page 58 of this prospectus. In this description, the references to “Issuer,” “we,” “us,” or “our” refer only to American Towers, Inc. and not to any of its Affiliates. References to “Parent” refer to American Tower Corporation and not to any of its Affiliates.

We issued the old notes, and will issue the new notes, under an indenture among us, the Guarantors and The Bank of New York, as trustee, in a transaction that is not subject to the registration requirements of the Securities Act. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended. The new notes and the old notes will be identical in all material respects, except that the new notes will be registered under the Securities Act and be free of any obligation regarding registration and will not be entitled to any additional interest. Accordingly, unless specifically stated to the contrary, the following description applies equally to the old notes and the new notes.

The following description is a summary of the material provisions of the indenture and the registration rights agreement relating to the notes. It does not restate those agreements in their entirety. We urge you to read the indenture and the registration rights agreement relating to the notes because they, and not this description, define your rights as Holders of the notes. Copies of the indenture and the registration rights agreement are available as set forth under “Where You Can Find More Information.” We use certain defined terms in this description that are not defined below under “—Certain Definitions” or elsewhere in this description; these terms have the meanings assigned to them in the indenture. The Parent is a guarantor of the notes, but the Parent and certain of its subsidiaries are generally not subject to the covenants in the indenture for the notes.

General

The notes:

•

are our general unsecured obligations;

•

are subordinated in right of payment to all our existing and future Senior Debt;

•

are pari passu in right of payment with all of our existing and future senior subordinated Indebtedness including our outstanding 12.25% Senior Subordinated Discount Notes; and

•

are unconditionally guaranteed by the Guarantors on a senior subordinated basis.

The notes are guaranteed by:

•

all of our Wholly Owned Domestic Restricted Subsidiaries;

•

American Tower International, Inc. and American Tower LLC (the “Sister Guarantors”);

•

all of the Wholly Owned Domestic Restricted Subsidiaries of the Sister Guarantors; and

•

the Parent.

Each guarantee of the notes:

•

is a general unsecured obligation of the Guarantor;

•

is subordinated in right of payment to all existing and future Senior Debt of that Guarantor; and

•

is pari passu in right of payment with all existing and future senior subordinated Indebtedness of that Guarantor, including its guarantee of our 12.25% Senior Subordinated Discount Notes.

Payments on the notes will be subordinated to the payment of Senior Debt of the Issuer and payments on the guarantees will be subordinated to the payment of Senior Debt of the relevant Guarantor. See “—Subordination” below. The indenture will permit the Issuer and the Guarantors to incur additional Senior Debt subject to the limitations described herein.

As of December 31, 2003, after giving effect to the “as adjusted” transactions described under “Capitalization,” the notes would rank:

•

pari passu with approximately $468.4 million of the Issuer’s outstanding 12.25% Senior Subordinated Discount Notes ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million);

•

subordinate to approximately $0.7 billion of indebtedness under the credit facilities and other senior indebtedness of the Issuer and certain non-guarantor subsidiaries; and

•

structurally senior to approximately $1.7 billion of indebtedness of the Parent.

As of December 31, 2003, after giving effect to the “as adjusted” transactions described under “Capitalization,” the guarantees of the Group Guarantors of the notes would rank:

•

pari passu with their guarantees of approximately $468.4 million of the Issuer’s outstanding 12.25% Senior Subordinated Discount Notes ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million);

•

subordinate to approximately $0.7 billion of indebtedness under the credit facilities and other senior indebtedness of the Issuer and certain non-guarantor subsidiaries; and

•

structurally senior to approximately $1.7 billion of indebtedness of the Parent.

The guarantee of the Parent of the notes would rank:

•

pari passu to its guarantee of approximately $468.4 million of the Issuer’s outstanding 12.25% senior subordinated discount notes ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million); and

•

subordinate to approximately $1.7 billion of indebtedness of the Parent, its guarantee of approximately $0.7 billion under the credit facilities and other senior indebtedness of the Issuer and certain non-guarantor subsidiaries.

All of the Subsidiaries of the Issuer other than ATS-Needham LLC, Haysville Towers, LLC, ATC Realty Holding, Inc., ATC Connecticut, Inc., ATC Westwood, Inc., ATC Presidential Way, Inc., 10 Presidential Way Associates, LLC, Unisite/OmniPoint FL Tower Venture, LLC, Unisite/OmniPoint NE Tower Venture, LLC and Unisite/OmniPoint PA Tower Venture, LLC will be “Restricted Subsidiaries” and all of the Subsidiaries of the Sister Guarantors are “Restricted Subsidiaries” notwithstanding the fact that such Subsidiaries are not Subsidiaries of the Issuer. However, under the circumstances described below under the subheading “—Certain Covenants—Designation of Restricted and Unrestricted Subsidiaries,” each of the Issuer and the Sister Guarantors will be permitted to designate certain of its Subsidiaries as “Unrestricted Subsidiaries” in addition to the Unrestricted Subsidiaries of the Issuer listed above. The Unrestricted Subsidiaries will not be subject to many of the restrictive covenants in the indenture and will not guarantee the notes.

Certain of the operations of the Issuer and the Sister Guarantors are conducted through their Subsidiaries and, therefore, each of the Issuer and the Sister Guarantors relies on the cash flow of its Subsidiaries to meet its obligations, including its obligations under the notes or the guarantees, as the case may be. Any right of the Issuer and the Sister Guarantors to receive assets of any of their Subsidiaries upon the liquidation or reorganization of the Subsidiaries, and the consequent right of the Holders of the notes to participate in those assets, will be effectively subordinated to the claims of that Subsidiary’s creditors, except to the extent that the

Issuer or the Sister Guarantor, as the case may be, is itself recognized as a creditor of such Subsidiary. If the Issuer or the Sister Guarantor, as the case may be, is recognized as a creditor of such Subsidiary, the claims of the Issuer or the Sister Guarantor, as the case may be, would still be subordinate in right of payment to any security interest in the assets of that Subsidiary and any indebtedness of that Subsidiary senior to that held by the Issuer or the Sister Guarantor, as the case may be. The Issuer and the Sister Guarantors have pledged to the lenders under the Credit Agreement the shares of their Subsidiaries and any indebtedness of those Subsidiaries owed to the Issuer or the Sister Guarantor, as the case may be.

Subject to the limitations set forth under “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock,” the Issuer may, without the consent of the holders of the notes, issue up to $100 million aggregate principal amount of additional notes having the same ranking and guarantees and the same interest rate, maturity and other terms as the notes. Any of these additional notes, along with the notes offered hereby and any notes issued in exchange for such notes, will constitute a single series of notes under the indenture. No additional notes may be issued if an Event of Default has occurred with respect to the notes.

Principal, Maturity and Interest

The Issuer issued the old notes with an aggregate principal amount of $400.0 million on November 18, 2003 in denominations of $1,000 and integral multiples of $1,000. The old notes and the new notes will mature on December 1, 2011.

The notes will accrue interest at a rate of 7.25% per annum from the date of issuance of the notes, or from the most recent interest payment date to which interest has been paid or duly provided for, and accrued and unpaid interest will be payable semi-annually in arrears on June 1 and December 1 of each year, which we refer to as interest payment dates, beginning June 1, 2004. Interest will be paid to the person in whose name a note is registered at the close of business on the May 15 or November 15, which we refer to as the record dates, immediately preceding the relevant interest payment date. Each payment of interest on the notes will include interest accrued through the day before the applicable interest payment date. Any payment required to be made on any day that is not a business day will be made on the next succeeding business day as if made on the date that the payment was due and no interest will accrue on that payment for the period from the original payment date to the date of that payment on the next succeeding business day. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

The trustee will initially act as paying agent and registrar. The Issuer may change the paying agent or registrar without prior notice to the Holders of the notes, and the Issuer or any of its Subsidiaries may act as paying agent or registrar. You may present the notes for conversion, registration of transfer and exchange, without service charge, at the office of our paying agent and registrar, in New York, and at the corporate trust office of the trustee in New York.

Transfer and Exchange

A Holder may transfer or exchange notes in accordance with the indenture. The registrar and the trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. Holders will be required to pay all taxes due on transfer. The Issuer is not required to transfer or exchange any note selected for redemption or any note tendered for repurchase. Also, the Issuer is not required to transfer or exchange any note for a period of 15 days before a selection of notes to be redeemed or for a period of 15 days before a record date for the payment of interest.

Note Guarantees

The notes are guaranteed by the Parent, all of the Wholly Owned Domestic Restricted Subsidiaries of the Issuer, the Sister Guarantors and all of the Wholly Owned Domestic Restricted Subsidiaries of the Sister Guarantors. The guarantees are joint and several obligations of the Guarantors. Each guarantee is subordinated to the prior payment in full of all Senior Debt of that Guarantor. The obligations of each Guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance under applicable law. See “Risk Factors—Federal and State statutes allow courts, under specific circumstances, to void guarantees and require note holders to return payments received from guarantors.”

A Group Guarantor may not sell or otherwise dispose of all or substantially all of its assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuer or another Group Guarantor, unless:

(1)

immediately after giving effect to that transaction, no Default or Event of Default exists; and

(2)

either:

(a)

the Person acquiring the property in any such sale or disposition or the Person formed by or surviving any such consolidation or merger assumes all the obligations of that Group Guarantor under the indenture, its guarantee and the registration rights agreement pursuant to a supplemental indenture satisfactory to the trustee; or

(b)

the Net Proceeds of such sale or other disposition are applied in accordance with the applicable provisions of the indenture.

The guarantee of a Group Guarantor will be released:

(1)

in connection with any sale or other disposition of all or substantially all of the assets of that Group Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Issuer, a Sister Guarantor or a Restricted Subsidiary, if the sale or other disposition complies with the “Asset Sale” provisions of the indenture;

(2)

in connection with any sale of Capital Stock of a Group Guarantor (as a result of which such Guarantor is no longer a Subsidiary of the Issuer or a Subsidiary of a Sister Guarantor or, in the case of the Sister Guarantors, a Subsidiary of the Parent and the Parent owns, directly or indirectly, no more than 25% of the outstanding Voting Stock of such Sister Guarantor) to a Person that is not (either before or after giving effect to such transaction) a Subsidiary of the Issuer or a Subsidiary of a Sister Guarantor or, in the case of the Sister Guarantors, a Subsidiary of the Parent, if the sale complies with the “Asset Sale” provisions of the indenture and, if not a sale of all such Capital Stock, the remaining Investment of the Issuer, the Sister Guarantors and the Restricted Subsidiaries in such Group Guarantor complies with the “Restricted Payments” provisions of the indenture;

(3)

if the Issuer or a Sister Guarantor designates such Group Guarantor as an Unrestricted Subsidiary in accordance with the applicable provisions of the indenture; or

(4)

if such Group Guarantor (other than a Sister Guarantor) is released from its guarantee under the Credit Agreement and any other Indebtedness incurred under clause (1) of the second paragraph of the covenant listed under “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock” and is released from its obligations, if any, as a co-borrower under the Credit Agreement and any other Indebtedness incurred under clause (1) of the second paragraph of the covenant listed under “—Certain Covenants— Incurrence of Indebtedness and Issuance of Preferred Stock.”

See “—Repurchase at the Option of Holders—Asset Sales” and “—Certain Covenants—Restricted Payments.”

The guarantee of the Parent will be released if the Parent is released from its guarantee under the Credit Agreement and any other Indebtedness incurred under clause (1) of the second paragraph of the covenant listed under “—Certain Covenants—Incurrence of Indebtedness and Issuance of Preferred Stock.”

If a Sister Guarantor is released from its guarantee, it will also be released from all of its obligations under the indenture. If any Group Guarantor is released from its guarantee, its Restricted Subsidiaries will also be released from their guarantees if they remain Subsidiaries of such Group Guarantor at such time.

Subordination

The payment of principal amount of, premium, if any, interest and Additional Interest, if any, on the notes will be subordinated to the prior payment in full of all Senior Debt of the Issuer, including Senior Debt incurred after the date of the indenture.

The holders of Senior Debt will be entitled to receive payment in full of all Obligations due in respect of Senior Debt (including interest after the commencement of any bankruptcy proceeding at the rate specified in the applicable Senior Debt) before the Holders of notes will be entitled to receive any payment with respect to the notes (except that Holders of notes may receive and retain Permitted Junior Securities and payments made from the trust described under “—Legal Defeasance and Covenant Defeasance”), in the event of any distribution to creditors of the Issuer:

(1)

in a liquidation or dissolution of the Issuer;

(2)

in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Issuer or its property;

(3)

in an assignment for the benefit of the Issuer’s creditors; or

(4)

in any marshaling of the Issuer’s assets and liabilities.

The Issuer also may not make any payment in respect of the notes (except in Permitted Junior Securities or from the trust described under “—Legal Defeasance and Covenant Defeasance”) if:

(1)

a payment default on Designated Senior Debt occurs and is continuing beyond any applicable grace period; or

(2)

any other default occurs and is continuing on any series of Designated Senior Debt that permits holders of that series of Designated Senior Debt to accelerate its maturity and the trustee receives a notice of such default (a “Payment Blockage Notice”) from the Issuer or the holders of any Designated Senior Debt.

Payments on the notes may and will be resumed:

(1)

in the case of a payment default, upon the date on which such default is cured or waived; and

(2)

in the case of a nonpayment default, upon the earlier of the date on which such nonpayment default is cured or waived or 179 days after the date on which the applicable Payment Blockage Notice is received, unless the maturity of any Designated Senior Debt has been accelerated.

No new Payment Blockage Notice may be delivered unless and until:

(1)

360 days have elapsed since the delivery of the immediately prior Payment Blockage Notice; and

(2)

all scheduled payments on the notes that have come due have been paid in full in cash.

No nonpayment default that existed or was continuing on the date of delivery of any Payment Blockage Notice to the trustee will be, or be made, the basis for a subsequent Payment Blockage Notice unless such default has been cured or waived for a period of not less than 180 days.

If the trustee or any Holder of the notes receives a payment in respect of the notes (except in Permitted Junior Securities or from the trust described under “—Legal Defeasance and Covenant Defeasance”) when:

(1)

the payment is prohibited by these subordination provisions; and

(2)

the trustee or the Holder has actual knowledge that the payment is prohibited;

the trustee or the Holder, as the case may be, will hold the payment in trust for the benefit of the holders of Senior Debt. Upon the proper written request of the holders of Senior Debt, the trustee or the Holder, as the case may be, will deliver the amounts in trust to the holders of Senior Debt or their proper representative.

The Issuer must promptly notify holders of Senior Debt if payment of the notes is accelerated because of an Event of Default.

The obligations of each Guarantor under its guarantee shall be subordinated to the Senior Debt of such Guarantor on the same basis as the notes are subordinated to Senior Debt of the Issuer.

As a result of the subordination provisions described above, in the event of a bankruptcy, liquidation or reorganization of the Issuer or any Guarantor, Holders of notes may recover less ratably than creditors of the Issuer or any Guarantor, as applicable, who are holders of Senior Debt. See “Risk Factors—Your right to receive payments on the notes is junior to our existing and future senior indebtedness.”

Optional Redemption

On or after December 1, 2007, the Issuer may redeem all or a part of the notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices, expressed as a percentage of the principal amount, set forth below plus accrued and unpaid interest and Additional Interest, if any, on the notes redeemed, to but excluding the applicable redemption date, if redeemed during the twelve-month period beginning on December 1 of the years indicated below:


Year	Percentage
2007	103.625	%
2008	101.813	%
2009 and thereafter	100.000	%

Prior to December 1, 2006, the Issuer may use the net cash proceeds of one or more Public Equity Offerings to redeem in the aggregate up to 35% of the aggregate principal amount of the notes originally issued at a redemption price equal to 107.25% of the principal amount thereof, plus accrued and unpaid interest and Additional Interest, if any, on the notes redeemed, to but excluding the applicable redemption date; provided that:

(1)

after giving effect to any such redemption at least 65% of the aggregate principal amount of the notes originally issued remains outstanding; and

(2)

the Issuer makes such redemption not more than 60 days after the consummation of a Public Equity Offering.

Selection and Notice

If less than all of the notes are to be redeemed at any time, the trustee will select notes for redemption as follows:

(1)

if the notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the notes are listed; or

(2)

if the notes are not listed on any national securities exchange, on a pro rata basis, by lot or by such method as the trustee deems fair and appropriate.

No notes of $1,000 principal amount or less can be redeemed in part. Notices of redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of notes to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the notes or a satisfaction and discharge of the indenture. Notices of redemption may not be conditional.

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the Holder of notes upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest and Additional Interest, if any, will cease to accrue on the notes or portion thereof called for redemption as long as the Issuer has deposited with the paying agent funds in satisfaction of the applicable redemption price pursuant to the indenture.

Repurchase at the Option of Holders

Change of Control

If a Change of Control occurs, each Holder of notes will have the right to require the Issuer to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000) of that Holder’s notes pursuant to the offer described below (a “Change of Control Offer”) on the terms set forth in the indenture. In the Change of Control Offer, the Issuer will offer a payment in cash equal to 101% of the principal amount of the notes plus accrued and unpaid interest and Additional Interest, if any, up to but not including the repurchase date, on the notes purchased (a “Change of Control Payment”). Within fifteen days following any Change of Control, the Issuer will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offering to repurchase notes on the date specified in the notice (the “Change of Control Payment Date”), which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed, pursuant to the procedures required by the indenture and described in such notice. The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the indenture by virtue of such conflict.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(1)

accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer;

(2)

deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered; and

(3)

deliver or cause to be delivered to the trustee the notes properly accepted together with an officer’s certificate stating the aggregate principal amount of notes or portions of notes being purchased by the Issuer.

The paying agent will promptly mail to each Holder of notes properly tendered the Change of Control Payment for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each new note will be in a principal amount of $1,000 or an integral multiple of $1,000.

A Change of Control is a default under the Credit Agreement, and other Indebtedness of the Parent, the Issuer and the Group Guarantors contain similar default provisions or a requirement that the obligor repurchase such Indebtedness. Prior to complying with any of the provisions of this “Change of Control” covenant, but in

any event within 90 days following a Change of Control, the Issuer will either repay all its outstanding Senior Debt or obtain the requisite consents, if any, under all agreements governing its outstanding Senior Debt to permit the repurchase of notes required by this covenant. However, no assurance can be given that the Issuer will be able to do so, or that it can obtain sufficient funds to repurchase notes tendered pursuant to a Change of Control Offer. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The provisions described above that require the Issuer to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of the indenture are applicable. Except as described above with respect to a Change of Control, the indenture does not contain provisions that permit the Holders of the notes to require that the Issuer repurchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

The Issuer will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in the indenture applicable to a Change of Control Offer made by the Issuer and purchases all notes properly tendered and not withdrawn under the Change of Control Offer.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of the properties or assets of the Issuer and its Restricted Subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a Holder of notes to require the Issuer to repurchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of the assets of the Issuer and its Restricted Subsidiaries taken as a whole to another Person or group may be uncertain.

Asset Sales

The Issuer and each Sister Guarantor will not, and will not permit any of its respective Restricted Subsidiaries to, consummate an Asset Sale, and the Parent will not, and will not permit any of its Subsidiaries to, consummate an Asset Sale in respect of Equity Interests of any Sister Guarantor, unless:

(1)

the Issuer, Sister Guarantor, Restricted Subsidiary, Parent or Subsidiary of the Parent, as the case may be, receives consideration at the time of the Asset Sale at least equal to the fair market value of the assets or Equity Interests issued or sold or otherwise disposed of;

(2)

the fair market value is determined by the Issuer’s or the Parent’s Board of Directors; and

(3)

except in the case of a Tower Asset Exchange or an Excluded International Sale, at least 75% of the consideration received in such Asset Sale by the Issuer, the Sister Guarantor or the Restricted Subsidiary, or, in the case of an Asset Sale in respect of Equity Interests of any Sister Guarantor, the Parent or Subsidiary of the Parent, is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash:

(a)

any liabilities of the Issuer, the Sister Guarantor or the Restricted Subsidiary, as the case may be, as shown on its most recent balance sheet (other than contingent liabilities and liabilities that are by their terms subordinated to the notes or any guarantee of the notes) that are assumed by the transferee of any assets pursuant to a customary novation agreement that releases the Issuer, the Sister Guarantor or the Restricted Subsidiary from further liability; and

(b)

any securities, notes or other obligations received by the Issuer, the Sister Guarantor, the Restricted Subsidiary, the Parent or any Subsidiary of the Parent, as the case may be, from the transferee that are converted by the receiving party into cash within 60 days of the applicable Asset Sale, to the extent of the cash received in that conversion.

Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Issuer, the Sister Guarantor, the Restricted Subsidiary, the Parent or the Subsidiary of the Parent, as the case may be, may apply those Net Proceeds at its option:

(1)

to repay or repurchase Senior Debt of the Issuer or a Group Guarantor and, if the Senior Debt repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto;

(2)

to repay or repurchase other Indebtedness of any Restricted Subsidiary of the Issuer or the Sister Guarantors that is not a Group Guarantor;

(3)

to acquire all or substantially all of the assets of, or a majority of the Voting Stock or other Equity Interests of, another Permitted Business to the extent such assets, Voting Stock or other Equity Interests are owned by the Issuer or a Group Guarantor;

(4)

to make a capital expenditure in the business of the Issuer and the Group Guarantors; or

(5)

to acquire other assets that are used or useful in a Permitted Business of the Issuer and the Group Guarantors.

Pending the final application of any Net Proceeds, they can be used to temporarily reduce revolving credit borrowings of the Issuer or any Group Guarantor or otherwise be invested in any manner that is not prohibited by the indenture. Notwithstanding the foregoing, if the Issuer, a Sister Guarantor or one of its Restricted Subsidiaries enters into a legally binding obligation to invest any Net Proceeds and such obligation is terminated prior to 365 days after the relevant Asset Sale, such Net Proceeds shall be applied as provided in clauses (1) through (5) above on or prior to the later of such 365th day and 60 days after such termination. This covenant will be deemed to be satisfied if the Parent or a Subsidiary of the Parent contributes the Net Proceeds from an Asset Sale in respect of Equity Interests of a Sister Guarantor to the common equity capital of the Issuer or another Sister Guarantor and the Issuer or such other Sister Guarantor applies such Net Proceeds in accordance with this covenant.

Any Net Proceeds from Asset Sales that are not applied or invested as provided in the preceding paragraph will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $15.0 million, the Issuer (together with the Parent or the relevant Subsidiary of the Parent if such Excess Proceeds include Net Proceeds in respect of an Asset Sale of Equity Interests of any Sister Guarantor which are not contributed to the common equity capital of the Issuer or a Sister Guarantor in accordance with the last sentence of the preceding paragraph) will make an Asset Sale Offer to all Holders of notes and all holders of other Indebtedness that is pari passu with the notes and/or the guarantees of the Group Guarantors containing provisions similar to those set forth in the indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer for notes will be equal to 100% of the principal amount plus premium, if any, accrued and unpaid interest and Additional Interest, if any, thereon up to but excluding the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, those Excess Proceeds may be used for any purpose not otherwise prohibited by the indenture. If the principal amount plus premium, if any, accrued and unpaid interest and Additional Interest, if any, on the notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the trustee will select the notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

The Issuer (and the Parent or Subsidiary of the Parent, if applicable) will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the Asset Sale provisions of the indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Asset Sale provisions of the indenture by virtue of such conflict.

The agreements governing the Issuer’s outstanding Senior Debt currently prohibit the Issuer from purchasing any notes, and also provide that certain change of control or asset sale events with respect to the Issuer and the Sister Guarantors would constitute a default under these agreements. Any future credit agreements or other agreements relating to Senior Debt to which the Issuer or the Sister Guarantors become a party may contain similar or more stringent restrictions and provisions. In the event a Change of Control or Asset Sale occurs at a time when the Issuer is prohibited from purchasing notes, the Issuer could seek the consent of its senior lenders to the purchase of notes or could attempt to refinance the borrowings that contain such prohibition. If the Issuer does not obtain such a consent or repay such borrowings, the Issuer will remain prohibited from purchasing notes. In such case, the Issuer’s failure to purchase tendered notes would constitute an Event of Default under the indenture that would, in turn, constitute a default under such Senior Debt. In such circumstances, the subordination provisions in the indenture would likely restrict payments to the Holders of notes.

Certain Covenants

Changes in Covenants when Notes Rated Investment Grade

If on any date following the date of the indenture:

(1)

the notes are rated Baa3 or better by Moody’s and BBB- or better by S&P (or, if either such entity ceases to rate the notes for reasons outside of the control of the Issuer, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Issuer as a replacement agency, if any such agency exists at such time); and

(2)

no Default or Event of Default shall have occurred and be continuing,

then, beginning on that day and subject to the provisions of the following paragraph, the covenants specifically listed under the following captions in this prospectus will be suspended:

(1)

“—Repurchase at the Option of Holders—Asset Sales;”

(2)

“—Restricted Payments;”

(3)

“—Incurrence of Indebtedness and Issuance of Preferred Stock;”

(4)

“—Limitation on Incurrence of Senior Subordinated Indebtedness;”

(5)

“—Dividend and Other Payment Restrictions Affecting Subsidiaries;”

(6)

“—Designation of Restricted and Unrestricted Subsidiaries;”

(7)

“—Transactions with Affiliates;”

(8)

clause (3)(x) of the covenant listed under “—Merger, Consolidation or Sale of Assets;”

(9)

clause 1(a) of the covenant listed under “—Sale and Leaseback Transactions;” and

(10)

the proviso to the last paragraph of the definition of “Unrestricted Subsidiary” under “—Certain Definitions.”

In the event the foregoing covenants are suspended pursuant to the preceding paragraph and the rating assigned by both such rating agencies should subsequently decline to below Baa3 or BBB-, respectively, the foregoing covenants shall be reinstituted as of and from the date of such rating decline. Compliance with the “Restricted Payments” covenant will be calculated as if it had been in effect since the date of the indenture except that no default will be deemed to have occurred solely by reason of a Restricted Payment made while that covenant was suspended, and no other Default will be deemed to have occurred with respect to the suspended covenants during the time they were suspended (or after that time based solely on events that occurred during that time). There can be no assurance that the notes will ever achieve an investment grade rating or that, if achieved, it will be maintained.

Restricted Payments

The Issuer and each Sister Guarantor will not, and each of them will not permit any of their respective Restricted Subsidiaries to, directly or indirectly:

(1)

declare or pay any dividend or make any other payment or distribution on account of the Issuer’s, any Sister Guarantor’s or any of the Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries) or to the direct or indirect holders of the Issuer’s, any Sister Guarantor’s or any of the Restricted Subsidiaries’ Equity Interests in their capacity as such (other than dividends or distributions payable in Equity Interests (other than Disqualified Stock) of the Issuer or a Sister Guarantor or to the Issuer or a Sister Guarantor or a Restricted Subsidiary);

(2)

purchase, redeem or otherwise acquire or retire for value (including, without limitation, in connection with any merger or consolidation involving the Issuer or a Sister Guarantor, as the case may be) any Equity Interests of the Issuer or a Sister Guarantor or of any Person of which the Issuer or a Sister Guarantor is a Subsidiary (other than any such Equity Interests owned by the Issuer, a Sister Guarantor or any of the Restricted Subsidiaries);

(3)

make any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the notes or the guarantees, except a payment of interest or principal at the Stated Maturity thereof (other than payments to the Issuer or a Sister Guarantor or payments by a Restricted Subsidiary to the Issuer or a Sister Guarantor or to another Restricted Subsidiary); or

(4)

make any Restricted Investment

(all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment:

(1)

no Default or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment; and

(2)

the Parent, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, would have had a Debt to Adjusted Consolidated Cash Flow Ratio no greater than 7.5 to 1.0; provided that this clause (2) shall not apply in connection with any Restricted Investment; and

(3)

such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Issuer, the Sister Guarantors and the Restricted Subsidiaries after the date of the indenture (excluding Restricted Payments permitted by clauses (2), (3), (4), (6), (7), (8) and (9) of the next succeeding paragraph), is less than the sum, without duplication, of:

(a)

100% of the Consolidated Cash Flow of the Parent for the period (taken as one accounting period) from the beginning of the first fiscal quarter of 2003 to the end of the Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if the Consolidated Cash Flow for such period is a deficit, less 100% of the deficit), less 1.4 times the Consolidated Interest Expense of the Parent since the beginning of the first fiscal quarter of 2003 to the end of the Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment, plus

(b)

(i) 100% of the aggregate net cash proceeds plus (ii) 70% of the aggregate value, as reflected on the balance sheets of the Issuer and the Sister Guarantors in accordance with GAAP using purchase accounting, of any Qualified Proceeds valued as of the date the Issuer’s or a Sister Guarantor’s Equity Interests were issued, sold or exchanged therefor, in each case, received by the Issuer or any Sister Guarantor since January 29, 2003 as a contribution to its common equity capital or from the issue, sale or exchange of Equity Interests of the Issuer and the Sister

Guarantor (other than Disqualified Stock) or from the issue or sale (whether before or after the date of the indenture) of Disqualified Stock or debt securities of the Issuer or any Sister Guarantor that have been converted after January 29, 2003 into Equity Interests (other than Equity Interests (or Disqualified Stock or convertible debt securities) sold to or held by a Subsidiary of the Issuer or of any Sister Guarantor and other than Disqualified Stock or convertible debt securities that have been converted into Disqualified Stock); provided that proceeds from an Asset Sale in respect of Equity Interests of a Sister Guarantor contributed to the common equity capital of the Issuer or a Sister Guarantor in accordance with the last sentence of the third paragraph of “—Repurchase at the Option of Holders—Asset Sales” will be excluded from this clause (3)(b); plus

(c)

to the extent that any Restricted Investment that was made after January 29, 2003 is sold for cash or otherwise liquidated or repaid for cash, the lesser of (i) the cash return of capital with respect to such Restricted Investment (less the cost of disposition, if any) and (ii) the initial amount of such Restricted Investment, plus

(d)

to the extent that any Unrestricted Subsidiary of the Issuer or any Sister Guarantor and all of its Subsidiaries are designated as or become Restricted Subsidiaries after the date of the indenture, the lesser of:

(i)

the fair market value of the Investments by the Issuer or the Sister Guarantors in such Subsidiaries as of the date they are designated or become Restricted Subsidiaries, or

(ii)

the sum of: (x) the fair market value of the Investments by the Issuer and the Sister Guarantors in such Subsidiaries as of the date on which such Subsidiaries were most recently designated as Unrestricted Subsidiaries, and (y) the amount of any Investments made in such Subsidiaries subsequent to such designation as Unrestricted Subsidiaries (and treated as Restricted Payments or excluded from clause (3)(b) pursuant to the proviso of clause (2) of the next paragraph) by the Issuer, a Sister Guarantor or any Restricted Subsidiary; plus

(e)

100% of any dividends or other distributions received by the Issuer, a Sister Guarantor or a Restricted Subsidiary after January 29, 2003 from an Unrestricted Subsidiary, to the extent that such dividends were not otherwise included in Consolidated Net Income of the Issuer and the Sister Guarantors (on a combined basis) for such period.

The preceding provisions will not prohibit:

(1)

the payment of any dividend or the making of any distribution within 60 days after the date of declaration of the dividend or distribution, if at the date of declaration the dividend payment or distribution would have complied with the provisions of the indenture;

(2)

(a) the making of any Investment or (b) the redemption, repurchase, retirement, defeasance or other acquisition of any subordinated Indebtedness or Equity Interests of the Issuer or a Sister Guarantor, in the case of (a) or (b), in exchange for, or out of the net cash proceeds from the substantially concurrent sale after the date of the indenture (other than to a Subsidiary of the Issuer or a Sister Guarantor) of Equity Interests of the Issuer or of a Sister Guarantor (other than any Disqualified Stock); provided that, in each case, the amount of any net cash proceeds (or other assets, as applicable) that are so utilized will be excluded from clause (3)(b) of the preceding paragraph;

(3)

the defeasance, redemption, repurchase or other acquisition of subordinated Indebtedness of the Issuer or any Group Guarantor with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness;

(4)

the payment of any dividend by a Restricted Subsidiary to the holders of its Equity Interests on a pro rata basis;

(5)

the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Parent, the Issuer, any Sister Guarantor or any Restricted Subsidiary held by any member of the Parent’s, the Issuer’s or any Sister Guarantor’s (or any of the Restricted Subsidiaries’) employees, management or directors pursuant to any management equity subscription agreement, stockholders agreement, stock option agreement or restricted stock agreement in effect as of the date of the indenture, or upon the death, disability or termination of employment or directorship of such persons; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $2.0 million in any twelve-month period;

(6)

any dividend, payment, advance or distribution made to the Parent, (a) which is applied by Parent to pay scheduled interest, dividends or principal or premium or liquidation preference at the Stated Maturity thereof or pursuant to a mandatory redemption or repurchase obligation on the Existing Parent Indebtedness or Additional Parent Indebtedness, (b) in an amount up to $66,687,876.58 (from restricted cash) which is to be used by the Parent to pay, repurchase, redeem or otherwise retire all or any portion of the Existing Parent Indebtedness, as provided in sub-clause (ii) of clause (6) of the second paragraph of Section 4.07 of the indenture relating to the 12.25% Senior Subordinated Discount Notes or (c) in accordance with clause (6) of the provisions of the indenture described below under the caption “—Transactions with Affiliates”;

(7)

the repurchase of Equity Interests (other than Disqualified Stock) of the Parent, the Issuer, any Sister Guarantor or any Restricted Subsidiary deemed to occur upon (a) exercise of stock options to the extent that such Equity Interests represent a portion of the exercise price of such options and (b) the withholding of a portion of such Equity Interests granted or awarded to an employee to pay taxes associated therewith;

(8)

the purchase of fractional shares of Equity Interests of the Parent, the Issuer, any Sister Guarantor or any Restricted Subsidiary arising out of stock dividends, splits or combinations or business combinations;

(9)

the repurchase of Disqualified Stock of the Parent, the Issuer, any Sister Guarantor or any Restricted Subsidiary in exchange for, or out of the proceeds of, other Disqualified Stock of such Person so long as the new Disqualified Stock is not manditorily redeemable, pursuant to a sinking fund obligation or otherwise, or redeemable at the option of the holder of such Disqualified Stock, in whole or in part, prior to the dates included in any similar provision contained in the Disqualified Stock being exchanged for or under circumstances not provided for; and

(10)

payments or distributions to stockholders of the Issuer or any Sister Guarantor pursuant to appraisal rights required under applicable law in connection with any consolidation, merger or transfer of assets that complies with the covenant described under “—Merger, Consolidation or Sale of Assets.”

The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred or issued by the Issuer, such Sister Guarantor or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.

The fair market value of any assets or securities that are required to be valued by this covenant will be determined by the Board of Directors whose resolution with respect thereto will be delivered to the trustee. Not later than the date of making any Restricted Payment, the Issuer will deliver to the trustee an officers’ certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by this “Restricted Payments” covenant were computed, together with a copy of any fairness opinion or appraisal required by the indenture.

Incurrence of Indebtedness and Issuance of Preferred Stock

The Issuer and each Sister Guarantor will not, and will not permit any of their respective Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or

indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Issuer and each Sister Guarantor will not issue any Disqualified Stock and will not permit any of their respective Restricted Subsidiaries to issue any shares of preferred stock.

The first paragraph of this covenant will not prohibit the incurrence of any of the following items of Indebtedness or the issuance of any of the following items of Disqualified Stock or preferred stock (collectively, “Permitted Debt”):

(1)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of Indebtedness under Credit Facilities in an aggregate principal amount (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Issuer, the Sister Guarantors and the Restricted Subsidiaries thereunder) incurred under this clause (1) at any one time outstanding not to exceed $1.6 billion less any amount applied to reduce Indebtedness incurred under this clause (1) as a result of the operation of clause (1) of the second paragraph of the covenant described above under “Repurchase at the Option of Holders—Asset Sales;”

(2)

the incurrence by the Issuer, the Sister Guarantors and the Restricted Subsidiaries of the Existing Indebtedness;

(3)

the incurrence by the Issuer and the Group Guarantors of Indebtedness represented by the notes and the related guarantees to be issued on the date of the indenture and the exchange notes and the related guarantees to be issued pursuant to the registration rights agreement;

(4)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of Indebtedness:

(a)

represented by Capital Lease Obligations incurred (i) in connection with the lease or other use of space or time on satellites or (ii) for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment, in each case used in the Teleports Business of the Issuer, such Sister Guarantor or such Restricted Subsidiary, or

(b)

represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Issuer, such Sister Guarantor or such Restricted Subsidiary, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (4), not to exceed $50.0 million at any time outstanding;

(5)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to extend, refinance, renew, replace, defease or refund Indebtedness (other than intercompany Indebtedness) or preferred stock or Disqualified Stock that was permitted by the indenture to be incurred under clauses (2), (3), (4), (5), or (11) of this paragraph;

(6)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of intercompany Indebtedness between or among the Issuer, any Sister Guarantor and any of the Restricted Subsidiaries and the issuance by any Restricted Subsidiary of shares of preferred stock to the Issuer, a Sister Guarantor or to another Restricted Subsidiary; provided, however, that:

(a)

if the Issuer or any Group Guarantor is the obligor on such Indebtedness, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations with respect to the notes, in the case of the Issuer, or the guarantee, in the case of a Group Guarantor; and

(b)

(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness or preferred stock being held by a Person other than the Issuer, a Sister Guarantor or a Restricted Subsidiary and (ii) any sale or other transfer of any such Indebtedness or preferred stock to a Person that is not either the Issuer, a Sister Guarantor or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Issuer, such Sister Guarantor

or such Restricted Subsidiary or issuance of the shares of preferred stock by such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of Interest and Currency Agreements not for speculative purposes;

(8)

the guarantee by the Issuer or any of the Group Guarantors of Indebtedness of the Issuer, a Sister Guarantor or a Restricted Subsidiary that was permitted to be incurred by another provision of this covenant;

(9)

the accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on preferred stock or Disqualified Stock in the form of additional shares of the same class of preferred stock or Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of this covenant; provided, in each such case, that the amount thereof is included in Consolidated Interest Expense of the Issuer and the Sister Guarantors as accrued;

(10)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of Acquired Debt in connection with a merger with or into a Restricted Subsidiary, or the acquisition of assets or a new Subsidiary; provided that, in the case of any such incurrence of Acquired Debt, such Acquired Debt was incurred by the prior owner of such assets or such Restricted Subsidiary prior to such acquisition by the Issuer, a Sister Guarantor or one of the Restricted Subsidiaries and was not incurred in connection with, or in contemplation of, the acquisition by the Issuer, a Sister Guarantor or one of the Restricted Subsidiaries; and provided further that, in the case of any incurrence pursuant to this clause (10), as a result of such acquisition by the Issuer, a Sister Guarantor or one of the Restricted Subsidiaries, the Debt to Adjusted Consolidated Cash Flow Ratio of the Parent at the time of incurrence of such Acquired Debt, after giving pro forma effect to such acquisition and incurrence as if the same had occurred at the beginning of the most recently ended four full fiscal quarter period of the Issuer for which internal financial statements are available, would have been the same or less than the Debt to Adjusted Consolidated Cash Flow Ratio of the Parent for the same period without giving pro forma effect to such incurrence;

(11)

the incurrence by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries of additional Indebtedness and/or the issuance of preferred stock or Disqualified Stock in an aggregate principal amount (or accreted value or liquidation preference, as applicable) at any time outstanding, including Indebtedness incurred to refund, refinance or replace any Indebtedness incurred pursuant to this clause (11), not to exceed $25.0 million;

(12)

Indebtedness of the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries represented by letters of credit, for the account of such Person, in order to provide security for workers’ compensation claims, payment obligations in connection with self-insurance or similar requirements in the ordinary course of business to the extent such letters of credit are not drawn upon or, if drawn upon, are reimbursed within five business days of the relevant draw; and

(13)

Indebtedness of the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, that such indebtedness is extinguished within three business days of incurrence.

For purposes of determining compliance with this “Incurrence of Indebtedness and Issuance of Preferred Stock” covenant, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (13) above, the Issuer and the Sister Guarantors will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this covenant. Indebtedness under the Credit Agreement outstanding on the date on which notes are first issued and authenticated under the indenture

will be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.

The indenture will also provide that the Issuer and each Sister Guarantor will not permit any of its respective Unrestricted Subsidiaries to incur any Indebtedness other than Non-Recourse Debt or Indebtedness owed to the Issuer, a Sister Guarantor or the Restricted Subsidiaries.

Limitation on Incurrence of Senior Subordinated Indebtedness

The Issuer will not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt of the Issuer and senior in any respect in right of payment to the notes. No Group Guarantor will incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to the Senior Debt of such Group Guarantor and senior in any respect in right of payment to such Group Guarantor’s guarantee.

Liens

The Issuer and each Sister Guarantor will not, and will not permit any of their respective Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind securing Indebtedness, Attributable Debt or trade payables (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all payments due under the indenture and the notes are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien.

Dividend and Other Payment Restrictions Affecting Subsidiaries

The Issuer and each Sister Guarantor will not, and will not permit any of their respective Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary to:

(1)

pay dividends or make any other distributions on its Capital Stock to the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits;

(2)

pay any Indebtedness owed to the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries;

(3)

make loans or advances to the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries; or

(4)

transfer any of its properties or assets to the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries.

However, the preceding restrictions will not apply to encumbrances or restrictions existing under or by reason of:

(1)

agreements governing Existing Indebtedness as in effect on the date of the indenture and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of thereof, provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to such dividend and other payment restrictions than those contained in those agreements on the date of the indenture unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Issuer’s Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding;

(2)

Indebtedness of the Issuer, any Sister Guarantor or any Restricted Subsidiary under any Credit Facility that is permitted to be incurred pursuant to the covenant under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock”; provided that such Credit Facility and Indebtedness

contain only such encumbrances and restrictions on such Restricted Subsidiary’s ability to engage in the activities set forth in clauses (1) through (4) of the preceding paragraph as are, at the time such Credit Facility is entered into or amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced, ordinary and customary for a Credit Facility of that type as determined in the good faith judgment of the Issuer’s Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding;

(3)

encumbrances and restrictions applicable to any Unrestricted Subsidiary, as the same are in effect as of the date on which the Subsidiary becomes a Restricted Subsidiary, and as the same may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced; provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacement or refinancings are no more restrictive, taken as a whole, with respect to the dividend and other payment restrictions than those contained in the applicable series of Indebtedness of such Subsidiary as in effect on the date on which such Subsidiary becomes a Restricted Subsidiary unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Issuer’s Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding;

(4)

any Indebtedness incurred in compliance with the covenant under the heading “—Incurrence of Indebtedness and Issuance of Preferred Stock” or any agreement pursuant to which such Indebtedness is issued if the encumbrance or restriction applies only in the event of a payment default or default with respect to a financial covenant contained in the Indebtedness or agreement and the encumbrance or restriction is not materially more disadvantageous to the Holders of the notes than is customary in comparable financings (as determined by the Issuer) and the Issuer determines that any such encumbrance or restriction will not materially affect the Issuer’s ability to pay the scheduled payments on the notes;

(5)

the indenture, the notes and the guarantees;

(6)

applicable law or any requirement of any regulatory body;

(7)

any instrument governing Indebtedness or Capital Stock of a Person acquired by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, and as such instrument may be amended, modified, restated, renewed, increased, supplemented, refunded, replaced or refinanced, provided that, in the case of Indebtedness, such Indebtedness was permitted by the terms of the indenture to be incurred and, provided further, that any such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing is no more restrictive, taken as a whole, with respect to the dividend and other payment restrictions than those contained in the instrument as in effect on the date on which the Person was acquired by the Issuer unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Issuer’s Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding;

(8)

customary non-assignment provisions in leases, licenses or other contracts entered into in the ordinary course of business;

(9)

purchase money obligations for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in clause (4) of the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock;”

(10)

any agreement for the sale or other disposition of a Restricted Subsidiary that restricts that Restricted Subsidiary pending its sale or other disposition;

(11)

Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are no more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced unless such restrictions are ordinary and customary for agreements of that type as determined in the good faith judgment of the Issuer’s Board of Directors (and evidenced in a board resolution), which determination shall be conclusively binding;

(12)

Liens permitted to be incurred under the provisions of the covenant described above under the caption “—Liens” that limit the right of the debtor to dispose of the assets subject to such Liens;

(13)

provisions with respect to the disposition or distribution of assets or property in joint venture agreements, shareholder agreements, partnership agreements and other similar agreements; and

restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

Merger, Consolidation or Sale of Assets

The Issuer may not, directly or indirectly: (1) consolidate or merge with or into another Person (whether or not the Issuer is the surviving corporation); or (2) sell, assign, transfer, convey or otherwise dispose of all or substantially all of the properties or assets of the Issuer and its Restricted Subsidiaries taken as a whole, in one or more related transactions, to another Person, unless:

(1)

either: (a) the Issuer is the surviving corporation; or (b) the Person formed by or surviving any such consolidation or merger (if other than the Issuer) or to which such sale, assignment, transfer, conveyance or other disposition has been made is a corporation organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

(2)

the Person formed by or surviving any such consolidation or merger (if other than the Issuer) or the Person to which such sale, assignment, transfer, conveyance or other disposition has been made assumes all the obligations of the Issuer under the notes, the indenture and the registration rights agreement pursuant to agreements reasonably satisfactory to the trustee; and

(3)

except in the case of (a) a merger of the Issuer with or into a Wholly Owned Restricted Subsidiary of the Issuer, a Sister Guarantor or a Wholly Owned Restricted Subsidiary of a Sister Guarantor, or (b) a merger entered into solely for the purpose of reincorporating the Issuer in another jurisdiction:

(x) (A)

in the case of a merger or consolidation in which the Issuer is the surviving corporation, the Parent, at the time of the transaction, after giving pro forma effect to the transaction as of such date for balance sheet purposes and as if the transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of the Parent for which internal financial statements are available for income statement purposes, (i) would have had a Debt to Adjusted Consolidated Cash Flow Ratio no greater than 7.5 to 1.0 or (ii) would have had a Debt to Adjusted Consolidated Cash Flow Ratio that was not greater than its Debt to Adjusted Consolidated Cash Flow Ratio for the same period without giving pro forma effect to such transaction, or

(B)

in the case of any other such transaction, the entity or Person formed by or surviving any such consolidation or merger (if other than the Issuer), or to which the sale, assignment, transfer, conveyance or other disposition shall have been made, at the time of the transaction, after giving pro forma effect to the transaction as of such date for balance sheet purposes and as if such transaction had occurred at the beginning of the most recently ended four full fiscal quarter period of such entity or Person for which internal financial statements are available for income statement purposes, (i) would have had a Debt to Adjusted Consolidated Cash Flow Ratio no greater than 7.5 to 1.0 or (ii) would have had a Debt to Adjusted Consolidated Cash Flow Ratio that was not greater than the Debt to Adjusted Consolidated Cash Flow Ratio of the Parent for the same period without giving pro forma effect to such transaction, and

(y)

immediately after such transaction, no Default or Event of Default exists.

In addition, the Issuer may not, directly or indirectly, lease all or substantially all of its properties or assets, in one or more related transactions, to any other Person. This “Merger, Consolidation or Sale of Assets” covenant will not apply to a sale, assignment, transfer, conveyance or other disposition of assets between or among the Issuer and any of the Guarantors.

Transactions with Affiliates

The Issuer and each Sister Guarantor will not, and will not permit any of their respective Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (each, an “Affiliate Transaction”), unless:

(1)

the Affiliate Transaction is on terms that, in the aggregate, are no less favorable to the Issuer, the relevant Sister Guarantor or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Issuer, such Sister Guarantor or such Restricted Subsidiary with an unrelated Person; and

(2)

the Issuer delivers to the trustee:

(a)

with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million, an officers’ certificate certifying that the Affiliate Transaction complies with clause (1) above;

(b)

with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, a resolution of the Issuer’s Board of Directors set forth in an officers’ certificate certifying that such Affiliate Transaction complies with clause (1) above and that such Affiliate Transaction has been approved by a majority of the members of the Board of Directors of the Issuer having no personal stake in such Affiliated Transaction (or, if there are no such members, by all of the directors and by the procedure described in clause (c) below); and

(c)

with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $25.0 million, an opinion as to the fairness to the Issuer of such Affiliate Transaction from a financial point of view issued by an accounting, appraisal or investment banking firm of national standing.

The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph:

(1)

any employment, compensation, benefit or indemnification agreement or arrangement (and any payments or other transactions pursuant thereto) entered into by the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries in the ordinary course of business with any officer, employee or director of the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries, including pursuant to stock option plans, stock ownership plans and employee benefit plans or arrangements;

(2)

transactions between or among the Issuer, the Sister Guarantors and/or the Restricted Subsidiaries;

(3)

transactions with a Person that is an Affiliate of the Issuer or a Sister Guarantor or a Restricted Subsidiary solely because the Issuer or a Sister Guarantor or a Restricted Subsidiary owns an Equity Interest in, or controls, such Person;

(4)

payment of reasonable director’s fees to Persons in an aggregate annual amount per Person that is substantially consistent with directors’ fees at comparable companies engaged in Permitted Businesses;

(5)

issuances or sales of Equity Interests (other than Disqualified Stock) of the Issuer;

(6)

payments to the Parent of customary tax sharing payments (including, without limitation, pursuant to the Tax Sharing Agreement) and of amounts necessary to pay Parent’s reasonable and customary administrative and overhead expenses and reasonable transaction costs related to financings;

(7)

any transaction undertaken pursuant to a contractual obligation as in effect on the date of the indenture; and

(8)

Restricted Payments that are permitted by the provisions of the indenture described above under the caption “—Restricted Payments” and Permitted Investments.

Additional Subsidiary Guarantees

If the Issuer or any Group Guarantor acquires or creates another Wholly Owned Domestic Restricted Subsidiary after the date of the indenture, then that newly acquired or created Wholly Owned Domestic Restricted Subsidiary will become a Guarantor and execute a supplemental indenture; provided that this covenant does not apply to all Subsidiaries that have properly been designated as Unrestricted Subsidiaries in accordance with the indenture for so long as they continue to constitute Unrestricted Subsidiaries.

Designation of Restricted and Unrestricted Subsidiaries

The Board of Directors of the Issuer may designate any Restricted Subsidiary of the Issuer or of a Sister Guarantor to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate fair market value of all outstanding Investments owned by the Issuer, the Sister Guarantors and the Restricted Subsidiaries in the Subsidiary properly designated will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under the first paragraph of the covenant described above under the caption “—Restricted Payments” or Permitted Investments, as determined by the Issuer. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of Directors of the Issuer may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if the redesignation would not cause a Default.

Sale and Leaseback Transactions

The Issuer and each Sister Guarantor will not, and will not permit any of their respective Restricted Subsidiaries to, enter into any sale and leaseback transaction; provided that the Issuer, any Sister Guarantor or any Restricted Subsidiary may enter into a sale and leaseback transaction if:

(1)

the Issuer, such Sister Guarantor or such Restricted Subsidiary, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the covenant described above under the caption “—Incurrence of Indebtedness and Issuance of Preferred Stock” and (b) incurred a Lien to secure such Indebtedness pursuant to the covenant described above under the caption “—Liens;”

(2)

the gross cash proceeds of that sale and leaseback transaction are at least equal to the fair market value, as determined in good faith by the Board of Directors of the Issuer and set forth in an officers’ certificate delivered to the trustee, of the property that is the subject of that sale and leaseback transaction; and

(3)

the transfer of assets in that sale and leaseback transaction is permitted by, and the Issuer applies the proceeds of such transaction in compliance with, the covenant described above under the caption “—Repurchase at the Option of Holders—Asset Sales.”

Reports

Whether or not required by the SEC, so long as any notes are outstanding, the Issuer will furnish to the Holders of notes, within the time periods specified in the SEC’s rules and regulations:

(1)

all quarterly and annual financial information of the Parent that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if the Parent were required to file such Forms, including Parent’s “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the Parent’s certified independent accountants;

(2)

the Tower Cash Flow for the most recently completed fiscal quarter and the Adjusted Consolidated Cash Flow and Non-Tower Cash Flow for the most recently completed four-quarter period, in each case of the Parent; and

(3)

all current reports that would be required to be filed with the SEC on Form 8-K if the Parent were required to file such reports.

Whether or not required by the SEC, all of the information and reports referred to in clauses (1) and (2) above shall be filed with the SEC for public availability within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing) and such information shall be made available to securities analysts and prospective investors upon request. In addition, the Issuer and the Guarantors have agreed that, for so long as any notes remain outstanding, they will furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

In the event that the Issuer is at any time required by the SEC to file reports under the Exchange Act, the Issuer shall, so long as any notes are outstanding furnish to the Holders of notes, within the time periods specified in the SEC’s rules and regulations, the foregoing required information.

Events of Default and Remedies

Each of the following is an Event of Default:

(1)

default for 30 days in the payment when due of interest on or Additional Interest with respect to the notes, whether or not prohibited by the subordination provisions of the indenture;

(2)

default in payment when due of the principal amount or accrued interest of, or premium, if any, on the notes, whether or not prohibited by the subordination provisions of the indenture;

(3)

failure by the Issuer to comply with the provisions described under the caption “—Certain Covenants—Merger, Consolidation or Sale of Assets” or failure by the Issuer to consummate a Change of Control Offer or Asset Sale Offer in accordance with the provisions of the indenture applicable to the offers;

(4)

failure by the Issuer or any of the Sister Guarantors for 30 days after notice by the trustee to comply with any of the other provisions described under the caption “— Certain Covenants” or “—Repurchase at the Option of Holders” or the failure by the Issuer or any of the Sister Guarantors for 60 days after notice to comply with any of the other agreements in the indenture or the notes;

(5)

default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Issuer or any of its Significant Subsidiaries (or the payment of which is guaranteed by the Issuer or any of its Significant Subsidiaries) whether such Indebtedness or guarantee now exists, or is created after the date of the indenture, if that default:

(a)

is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”); or

(b)

results in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $20.0 million or more;

(6)

failure by the Issuer or any of its Significant Subsidiaries to pay final judgments against any of them which are not covered by adequate insurance by a solvent insurer of national or international reputation which has acknowledged its obligations in writing, aggregating in excess of $20.0 million, which judgments are not paid, bonded, discharged or stayed for a period of 60 days; and

(7)

except as permitted by the indenture, any guarantee of the notes by any Significant Subsidiary of the Issuer shall be held in final and non-appealable judgment to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any such Guarantor that is a Significant Subsidiary of the Issuer, or any Person acting on behalf of any such Guarantor, shall in writing deny or disaffirm its obligations under its guarantee; and

(8)

certain events of bankruptcy or insolvency described in the indenture with respect to the Issuer, the Sister Guarantors or any of their Significant Subsidiaries.

In the case of an Event of Default arising under clause (8) above, the principal amount of, premium, if any, and any accrued and unpaid interest, including Additional Interest, if any, on all outstanding notes will become due and payable immediately, without further action or notice. If any other Event of Default occurs and is continuing, the trustee or the Holders of at least 25% in principal amount of the then outstanding notes may declare the principal amount of, premium, if any, and any accrued and unpaid interest, including Additional Interest, if any, on all outstanding notes to be due and payable immediately.

Holders of the notes may not enforce the indenture or the notes except as provided in the indenture. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding notes may direct the trustee in its exercise of any trust or power. The trustee may withhold from Holders of the notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment on the notes.

The Holders of a majority in aggregate principal amount of the notes then outstanding by notice to the trustee may on behalf of the Holders of all of the notes waive any existing Default or Event of Default and its consequences under the indenture except a continuing Default or Event of Default in the payment of the principal amount, premium, if any, and any accrued and unpaid interest, including Additional Interest, if any, on the notes.

The Issuer is required to deliver to the trustee annually a statement regarding compliance with the indenture. Upon becoming aware of any Default or Event of Default, the Issuer is required to deliver to the trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Stockholders

No director, officer, employee, incorporator or stockholder of the Issuer or any Guarantor, as such, will have any liability for any obligations of the Issuer or the Guarantors under the notes, the indenture, the guarantees, the registration rights agreement or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of notes by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the notes. The waiver may not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

The Issuer may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding notes and all obligations of the Guarantors discharged with respect to their guarantees (“Legal Defeasance”) except for:

(1)

the rights of Holders of outstanding notes to receive payments in respect of the principal amount, premium, interest and Additional Interest, if any, on such notes when such payments are due from the trust referred to below;

(2)

the Issuer’s obligations with respect to the notes concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(3)

the rights, powers, trusts, duties and immunities of the trustee, and the Issuer’s and the Guarantor’s obligations in connection therewith; and

(4)

the Legal Defeasance provisions of the indenture.

In addition, the Issuer may, at its option and at any time, elect to have the obligations of the Issuer and the Guarantors released with respect to certain covenants that are described in the indenture (“Covenant Defeasance”) and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the notes. In the event Covenant Defeasance occurs, certain events described under “—Events of Default and Remedies” but not including non-payment and bankruptcy, receivership, rehabilitation and insolvency events with respect to the Issuer will no longer constitute an Event of Default with respect to the notes.

In order to exercise either Legal Defeasance or Covenant Defeasance:

(1)

the Issuer must irrevocably deposit with the trustee, in trust, for the benefit of the Holders of the notes, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal amount and accrued interest, or premium and Additional Interest, if any, on the outstanding notes on the stated maturity or on the applicable redemption date, as the case may be, and the Issuer must specify whether the notes are being defeased to maturity or to a particular redemption date;

(2)

in the case of Legal Defeasance, the Issuer has delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that (a) the Issuer has received from, or there has been published by, the Internal Revenue Service a ruling or (b) since the date of the indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel will confirm that, the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3)

in the case of Covenant Defeasance, the Issuer has delivered to the trustee an opinion of counsel reasonably acceptable to the trustee confirming that the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4)

no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit);

(5)

such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the indenture) to which the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries is a party or by which the Issuer, any Sister Guarantor or any of the Restricted Subsidiaries is bound;

(6)

the Issuer must have delivered to the trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally;

(7)

the Issuer must deliver to the trustee an officers’ certificate stating that the deposit was not made by the Issuer with the intent of preferring the Holders of notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding creditors of the Issuer or others; and

(8)

the Issuer must deliver to the trustee an officers’ certificate and an opinion of counsel, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Amendment, Supplement and Waiver

Except as provided in the next three succeeding paragraphs, the indenture or the notes may be amended or supplemented with the consent of the Holders of at least a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes), and any existing default or compliance with any provision of the indenture or the notes may be waived with the consent of the Holders of a majority in principal amount of the then outstanding notes (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, notes).

Without the consent of each Holder affected, an amendment or waiver may not (with respect to any notes held by a non-consenting Holder):

(1)

reduce the principal amount of notes whose Holders must consent to an amendment, supplement or waiver;

(2)

reduce the principal amount of or change the fixed maturity of any note or alter the provisions with respect to the redemption of the notes (other than provisions relating to the covenants described above under the caption “—Repurchase at the Option of Holders”) or amend or modify the calculation, or time of payment, of interest, including defaulted interest, on the notes;

(3)

waive a Default or Event of Default in the payment on the notes (except a rescission of acceleration of the notes by the Holders of at least a majority in aggregate principal amount of the notes then outstanding and a waiver of the payment default that resulted from such acceleration);

(4)

make any note payable in money other than that stated in the notes;

(5)

make any change in the provisions of the indenture relating to waivers of past Defaults or the rights of Holders of notes to receive payments on the notes;

(6)

waive a redemption payment with respect to any note (other than a payment required by one of the covenants described above under the caption “—Repurchase at the Option of Holders”);

(7)

release any Guarantor from any of its obligations under its guarantee or the indenture, except in accordance with the terms of the indenture; or

(8)

make any change in the preceding amendment and waiver provisions.

In addition, any amendment to, or waiver of, the provisions of the indenture relating to subordination that adversely affects the rights of the Holders of the notes will require the consent of the Holders of at least 66 2/3% in aggregate principal amount of notes then outstanding.

Notwithstanding the preceding, without the consent of any Holder of notes, the Issuer, the Guarantors and the trustee may amend or supplement the indenture or the notes:

(1)

to cure any ambiguity, defect or inconsistency;

(2)

to provide for uncertificated notes in addition to or in place of certificated notes or to alter the provisions of Article 2 of the indenture (relating to the form of the notes, procedures for execution, authentication, delivery and transfer of the notes and similar matters (including the related definitions)) in a manner that does not materially adversely affect any Holder or any holder of a beneficial interest in the notes;

(3)

to provide for the assumption of the Issuer’s obligations to Holders of notes in the case of a merger or consolidation or sale of all or substantially all of the Issuer’s assets;

(4)

to make any change that would provide any additional rights or benefits to the Holders of notes or that does not adversely affect the legal rights under the indenture of any such Holder;

(5)

to comply with requirements of the SEC in order to effect or maintain the qualification of the indenture under the Trust Indenture Act;

(6)

to conform the text of the indenture, the guarantees or the notes to any provision of this Description of Notes to the extent that such provision in this “Description of Notes” was intended to be a verbatim recitation of a provision of the indenture, the guarantees or the notes;

(7)

to add additional guarantors and guarantees; or

(8)

to evidence and provide for the acceptance of the appointment under the Indenture of a successor trustee.

Satisfaction and Discharge

The indenture will be discharged and will cease to be of further effect as to all notes issued thereunder, when:

(1)

either:

(a)

all notes that have been authenticated, except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has been deposited in trust and thereafter repaid to the Issuer, have been delivered to the trustee for cancellation; or

(b)

all notes that have not been delivered to the trustee for cancellation have become due and payable by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Issuer or any Guarantor has irrevocably deposited or caused to be deposited with the trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the notes not delivered to the trustee for cancellation for the principal amount plus accrued interest, premium and Additional Interest, if any, on all notes;

(2)

no Default or Event of Default has occurred and is continuing on the date of the deposit or will occur as a result of the deposit and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuer or any Guarantor is a party or by which the Issuer or any Guarantor is bound;

(3)

the Issuer or any Guarantor has paid or caused to be paid all sums payable by it under the indenture; and

(4)

the Issuer has delivered irrevocable instructions to the trustee under the indenture to apply the deposited money toward the payment of the notes at maturity or the redemption date, as the case may be.

In addition, the Issuer must deliver an officers’ certificate to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

Concerning the Trustee

If the trustee becomes a creditor of the Issuer or any Guarantor, the indenture limits its right to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim as security or otherwise. The trustee will be permitted to engage in other transactions; however, if it acquires any conflicting interest it must eliminate such conflict within 90 days, apply to the SEC for permission to continue or resign.

The Holders of a majority in principal amount of the then outstanding notes will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee, subject to certain exceptions. The indenture provides that in case an Event of Default occurs and is continuing, the trustee will be required, in the exercise of its power, to use the degree of care of a prudent man in the conduct of his own affairs. Subject to such provisions, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any Holder of notes, unless such Holder has offered to the trustee security and indemnity satisfactory to it against any loss, liability or expense.

Registration Rights; Additional Interest

The following description is a summary of the material provisions of the registration rights agreement. It does not restate that agreement in its entirety. We urge you to read the registration rights agreement in its entirety because it, and not this description, defines your registration rights as Holders of these notes.

The Issuer, the Guarantors and the Initial Purchasers entered into a registration rights agreement on November 18, 2003. Pursuant to the registration rights agreement, the Issuer and the Guarantors agreed to file with the SEC the Exchange Offer Registration Statement, of which this prospectus forms a part, on the appropriate form under the Securities Act with respect to the Exchange Notes. Upon the effectiveness of the Exchange Offer Registration Statement, the Issuer and the Guarantors will offer to the Holders of Transfer Restricted Securities pursuant to the Exchange Offer who are able to make certain representations the opportunity to exchange their Transfer Restricted Securities for Exchange Notes.

If:

(1)

the Issuer and the Guarantors are not

(a)

required to file the Exchange Offer Registration Statement; or

(b)

permitted to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or SEC policy; or

(2)

any Holder of Transfer Restricted Securities notifies the Issuer prior to the 20th day following consummation of the Exchange Offer that:

(a)

it is prohibited by law or SEC policy from participating in the Exchange Offer; or

(b)

it may not resell the Exchange Notes acquired by it in the Exchange Offer to the public without delivering a prospectus and the prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales; or

(c)

it is a broker-dealer and owns notes acquired directly from the Issuer or an affiliate of the Issuer,

the Issuer and the Guarantors will file with the SEC a Shelf Registration Statement to cover resales of the notes by the Holders of the notes who satisfy certain conditions relating to the provision of information in connection with the Shelf Registration Statement.

The Issuer and the Guarantors will use their reasonable best efforts to cause the applicable registration statement to be declared effective as promptly as possible by the SEC.

For purposes of the preceding, “Transfer Restricted Securities” means each note until:

(1)

the date on which such note has been exchanged by a Person other than a broker-dealer for an Exchange Note in the Exchange Offer;

(2)

following the exchange by a broker-dealer in the Exchange Offer of a note for an Exchange Note, the date on which such Exchange Note is sold to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement;

(3)

the date on which such note has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement; or

(4)

the date on which such note is distributed to the public pursuant to Rule 144 under the Securities Act.

The registration rights agreement provides that:

(1)

the Issuer and the Guarantors will use their reasonable best efforts to file an Exchange Offer Registration Statement with the SEC on or prior to February 16, 2004;

(2)

the Issuer and the Guarantors will use their reasonable best efforts to have the Exchange Offer Registration Statement declared effective by the SEC on or prior to May 16, 2004;

(3)

unless the Exchange Offer would not be permitted by applicable law or SEC policy, the Issuer and the Guarantors will

(a)

commence the Exchange Offer; and

(b)

use their best efforts to issue on or prior to 30 business days, or longer, if required by the federal securities laws, after the date on which the Exchange Offer Registration Statement was declared effective by the SEC, Exchange Notes in exchange for all notes tendered prior thereto in the Exchange Offer; and

(4)

if obligated to file the Shelf Registration Statement, the Issuer and the Guarantors will use their reasonable best efforts to file the Shelf Registration Statement with the SEC on or prior to 30 days after such filing obligation arises and to cause the Shelf Registration to be declared effective by the SEC on or prior to 90 days after such obligation arises.

If:

(1)

the Issuer and the Guarantors fail to file any of the registration statements required by the registration rights agreement on or before the date specified for such filing; or

(2)

any of such registration statements is not declared effective by the SEC on or prior to the date specified for such effectiveness (the “Effectiveness Target Date”); or

(3)

the Issuer and the Guarantors fail to consummate the Exchange Offer within 30 business days of the Effectiveness Target Date with respect to the Exchange Offer Registration Statement; or

(4)

the Shelf Registration Statement or the Exchange Offer Registration Statement is declared effective but thereafter ceases to be effective or usable in connection with resales of Transfer Restricted Securities during the periods specified in the registration rights agreement (each such event referred to in clauses (1) through (4) above, a “Registration Default”),

then the Issuer and the Guarantors will pay additional interest (“Additional Interest”) to each Holder of notes, with respect to the first 90-day period immediately following the occurrence of the first Registration Default in an amount equal to $.05 per week per $1,000 principal amount of notes held by such Holder.

The amount of Additional Interest will increase by an additional $.05 per week per $1,000 principal amount of notes with respect to each subsequent 90-day period until all Registration Defaults have been cured, up to a

maximum amount of Additional Interest for all Registration Defaults of $.25 per week per $1,000 principal amount of notes. In no event shall Additional Interest be required for more than one of these Registration Defaults at any given time.

All accrued Additional Interest will be paid by the Issuer and the Guarantors on each Damages Payment Date to the Global Note Holder by wire transfer of immediately available funds or by federal funds check and to Holders of Certificated Notes by wire transfer to the accounts specified by them or by mailing checks to their registered addresses if no such accounts have been specified.

Following the cure of all Registration Defaults, the accrual of Additional Interest will cease.

Holders of notes will be required to make certain representations to the Issuer (as described in the registration rights agreement) in order to participate in the Exchange Offer.

Certain Definitions

Set forth below are certain defined terms used in the indenture. Reference is made to the indenture for a full disclosure of all such terms, as well as any other capitalized terms used herein for which no definition is provided.

Book-Entry System

General

The new notes will be issued in registered, global form in minimum denominations of $1,000 and integral multiples of $1,000 in excess thereof (the “Global Notes”). The Global Notes will be deposited upon issuance with the trustee as custodian for The Depository Trust Company (“DTC”), in New York, New York, and registered in the name of DTC or its nominee for credit to an account of a direct or indirect participant in DTC, including the Euroclear System (“Euroclear”) or Clearstream Banking, S.A. (“Clearstream”), as described below under “—Depositary Procedures.”

Except as set forth below, the Global Notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in certificated form except in the limited circumstances described below under “—Exchange of Book-Entry Notes for Certificated Notes.” Transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of Euroclear and Clearstream), which may change from time to time.

Depositary Procedures

The following description of the operations and procedures of DTC, Euroclear and Clearstream are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to changes by them. The Issuer takes no responsibility for these operations and procedures and urges investors to contact the systems or their participants directly to discuss these matters.

DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the “Participants”) and facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the initial purchasers), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the “Indirect Participants”). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through Participants or Indirect Participants. DTC has no knowledge of the identity of beneficial owners of securities held by or on behalf of DTC. DTC’s records reflect only the identity of Participants to whose accounts securities are credited. The ownership interests and transfer of ownership interests of each beneficial owner of each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

Pursuant to procedures established by DTC:

•

upon deposit of the Global Notes, DTC will credit the accounts of Participants with portions of the principal amount of the Global Notes; and

•

ownership of such interests in the Global Notes will be maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interests in the Global Notes).

Investors in the Global Notes may hold their interests therein directly through DTC, if they are Participants in such system, or indirectly through organizations (including Euroclear and Clearstream) that are Participants or Indirect Participants in such system. Euroclear and Clearstream will hold interests in the notes on behalf of their participants through customers’ securities accounts in their respective names on the books of their respective depositaries, which are Euroclear Bank, S.A./N.V., as operator of Euroclear, and Citibank, N.A., as operator of Clearstream. The depositaries, in turn, will hold interests in the notes in customers’ securities accounts in the depositaries’ names on the books of DTC.

All interests in a Global Note, including those held through Euroclear or Clearstream, will be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream will also be subject to the procedures and requirements of these systems. The laws of some states require that certain persons take physical delivery of certificates evidencing securities they own. Consequently, the ability to transfer beneficial interests in a Global Note to such persons will be limited to that extent. Because DTC can act only on behalf of Participants, which in turn act on behalf of Indirect Participants, the ability of beneficial owners of interests in a Global Note to pledge such interests to persons or entities that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests. For certain other restrictions on the transferability of the notes, see “—Exchange of Book-Entry Notes for Certificated Notes.”

Except as described below, owners of interests in the Global Notes will not have notes registered in their names, will not receive physical delivery of notes in certificated form and will not be considered the registered owners or holders thereof under the Indenture.

Payments in respect of the principal of and premium, if any, and interest on a Global Note registered in the name of DTC or its nominee will be payable by the trustee (or the paying agent if other than the trustee) to DTC

in its capacity as the registered holder under the Indenture. The Issuer and the trustee will treat the persons in whose names the notes, including the Global Notes, are registered as the owners thereof for the purpose of receiving such payments. Consequently, none of the Issuer, the trustee or any agent of the Issuer or the trustee has or will have any responsibility or liability for:

•

any aspect of DTC’s records or any Participant’s or Indirect Participant’s records relating to or payments made on account of beneficial ownership interests in the Global Notes, or for maintaining, supervising or reviewing any of DTC’s records or any Participant’s or Indirect Participant’s records relating to the beneficial ownership interests in the Global Notes; or

•

any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants.

DTC has advised us that its current practice, upon receipt of any payment in respect of securities such as the notes (including principal and interest), is to credit the accounts of the relevant Participants with the payment on the payment date in amounts proportionate to their respective holdings in the principal amount of the relevant security as shown on the records of DTC, unless DTC has reason to believe it will not receive payment on such payment date. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or the Issuer. Neither the Issuer nor the trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the notes, and the Issuer and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

Except for trades involving only Euroclear and Clearstream participants, interests in the Global Notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System and secondary market trading activity in such interests will therefore settle in immediately available funds, subject in all cases to the rules and procedures of DTC and its Participants.

Transfers between Participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

Cross-market transfers between Participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by their depositaries. Cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in that system in accordance with the rules and procedures and within the established deadlines (Brussels time) of that system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositaries to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear and Clearstream participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream.

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC will be credited and reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

DTC has advised us that it will take any action permitted to be taken by a holder of notes only at the direction of one or more Participants to whose account with DTC interests in the Global Notes are credited and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have given such direction.

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and the procedures may be discontinued at any time. Neither the Issuer nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

The information in this section concerning DTC, Euroclear and Clearstream and their book-entry systems has been obtained from sources that the Issuer believes to be reliable, but the Issuer takes no responsibility for the accuracy thereof.

Exchange of Book-Entry Notes for Certificated Notes

The Global Notes are exchangeable for certificated notes in definitive, fully registered form without interest coupons (“Certificated Notes”) only in the following limited circumstances:

•

DTC (1) notifies the Issuer that it is unwilling or unable to continue as depositary for the Global Note and we fail to appoint a successor depositary or (2) has ceased to be a clearing agency registered under the Exchange Act,

•

the Issuer, at its option, notifies the trustee in writing that it elects to cause the issuance of the notes in the form of Certificated Notes, or

•

if there shall have occurred and be continuing an Event of Default with respect to the notes.

In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of DTC (in accordance with its customary procedures).

DESCRIPTION OF OTHER INDEBTEDNESS

Below is a summary of our credit facilities, discount notes and warrants, senior notes and convertible notes. It is qualified in its entirety by the terms of the actual agreements that are summarized.

Credit Facilities. As of December 31, 2003, our credit facilities provide us with a borrowing capacity of up to $999.7 million and consist of:

•

a $343.2 million revolving credit facility, of which $48.2 million was drawn and against which $25.7 million of undrawn letters of credit were outstanding, maturing on June 30, 2007;

•

a $389.5 million multi-draw Term Loan A, which was fully drawn, maturing on June 30, 2007; and

•

a $267.0 million Term Loan B, which was fully drawn, maturing on December 31, 2007.

In January 2004, we amended our credit facilities primarily to facilitate American Tower Corporation’s offering of its 7.50% senior notes due 2012. The amendment required that the net proceeds be used to prepay obligations under its convertible notes and also removed the requirement that any remaining proceeds from our August 2003 equity offering held as restricted cash and investments on August 4, 2004 be contributed to the borrower subsidiaries. We also refinanced our $267.0 million Term Loan B under our credit facilities with a new Term Loan C due December 31, 2007. The new Term Loan C has substantially the same terms as Term Loan B, except that the interest rate spreads for the LIBOR and base rate loans were reduced from 3.5% to 2.25% above LIBOR and from 2.5% to 1.25% above the base rate. In February 2004, we voluntarily prepaid $21.0 million of Term Loan A.

Our principal operating subsidiaries (other than Verestar) are the borrowers under our credit facilities. Borrowings under the credit facilities are subject to compliance with certain financial ratios. We are required under our credit facilities to make scheduled amortization payments in increasing amounts designed to repay the loans at maturity. During 2004, we will be required to pay approximately $18.0 million of the term loans each quarter.

Our credit facilities contain certain financial ratios and operational covenants and other restrictions with which the borrowers 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. They also restrict American Tower Corporation’s ability, as the parent company of the borrowers and guarantors, 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 borrowers and the restricted subsidiaries, and substantially all outstanding capital stock and other debt and equity interests of all of our direct and indirect subsidiaries.

In connection with the offering of the old notes, we entered into an amendment to our credit facilities to permit that offering and to extend the effective date of the requirement to repay indebtedness using excess cash flow from April 2004 to April 2005.

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

The discount notes rank junior in right of payment to all existing and future senior indebtedness of ATI, the sister guarantors and their domestic subsidiaries and structurally senior in right of payment to all of American Tower Corporation’s existing and future indebtedness. The discount notes are jointly and severally guaranteed on a senior subordinated basis by American Tower Corporation and all of its wholly owned domestic subsidiaries, including the sister guarantors. The discount notes will rank equally with the notes offered hereby and any other future senior subordinated obligations of ATI.

As part of the discount notes offering, we issued warrants to purchase an aggregate of 11.4 million shares of our Class A common stock at a price of $0.01 per share. The warrants and the discount notes were originally

issued together as 808,000 units, each unit consisting of (1) one discount note having a principal value of $1,000 at maturity, and (2) one warrant to purchase 14.0953 shares of our Class A common stock at $0.01 per share. The warrants are exercisable at any time on or after January 29, 2006 and will expire on August 1, 2008. The shares underlying the warrants represented approximately 5.2% of our outstanding common stock as of December 31, 2003 (assuming exercise of all warrants).

As of December 31, 2003, amounts outstanding under the discount notes approximated $468.4 million ($424.2 million in accreted value, net of the allocated fair value of warrants of $44.2 million).

9³/8% Senior Notes. As of December 31, 2003, American Tower Corporation had outstanding an aggregate principal amount of $1.0 billion of 9³/8% 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 American Tower Corporation’s ability to incur additional debt, guarantee debt, pay dividends, make certain investments and, as in the credit facilities, use the proceeds from asset sales.

2.25% and 6.25% Convertible Notes. In October 1999, American Tower Corporation issued 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, and 6.25% convertible notes due 2009 in an aggregate principal amount of $300.0 million. On October 22, 2003, American Tower Corporation completed a cash tender offer for its 2.25% convertible notes due 2009. Convertible notes in an aggregate face amount of $104.9 million were tendered in exchange for approximately $84.2 million in cash. As of December 31, 2003, the total amounts outstanding under the 2.25% convertible notes and 6.25% convertible notes were $0.1 million and $212.7 million, respectively. In February 2004, American Tower Corporation redeemed all of its outstanding $212.7 million principal amount of 6.25% convertible notes. The 6.25% convertible notes were redeemed pursuant to the terms of the indenture at 102.083% of the principal amount plus unpaid and accrued interest. The total aggregate redemption price was $221.9 million, including $4.8 million of accrued interest.

5.0% Convertible Notes. In February 2000, American Tower Corporation 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 American Tower Corporation’s Class A common stock at a conversion price of $51.50 per share. The indenture governing the 5.0% convertible notes does not contain any restrictions on the payment of dividends, the incurrence of debt or the repurchase of American Tower Corporation’s equity securities or any financial covenants.

Holders may require us to repurchase all or any of the 5.0% convertible notes on or after February 20, 2007 at their principal amount, together with accrued and unpaid interest. We may, subject to certain conditions in the indenture governing the 5.0% convertible notes, 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 from the proceeds of borrowings under the credit facilities or from funds from any of its borrowers.

As of December 31, 2003, after giving effect to the repurchase of $51.2 million of our 5.0% convertible notes occurring in the first quarter of 2004, the total principal amount outstanding under the 5.0% convertible notes was approximately $298.2 million.

3.25% Convertible Notes. In August 2003, American Tower Corporation issued 3.25% convertible notes due 2010 in an aggregate principal amount of $210.0 million. The 3.25% convertible notes are convertible into shares of American Tower Corporation’s Class A common stock at a conversion price of $12.22 per share. The indenture under which the 3.25% convertible notes were issued does not contain any sinking fund or mandatory redemption requirement for the 3.25% convertible notes prior to maturity nor do holders have the right to require us to repurchase all or any of the 3.25% convertible notes prior to maturity. The indenture under which the 3.25% convertible notes were issued does not contain any restrictions on the payment of dividends, the increase of debt or liens or the repurchase of American Tower Corporation’s equity securities or any financial covenants. As of August 6, 2008, American Tower Corporation may redeem the 3.25% convertible notes, at its option, in whole or

in part at a redemption price initially of 100.929% of the principal amount. The redemption price declines ratably immediately after August 1 of each following year to 100% of the principal amount in 2010. We are also required to pay accrued and unpaid interest as part of all note redemptions.

As of December 31, 2003, the total amount outstanding under the 3.25% convertible notes was $210.0 million.

7.50% Senior Notes. In February 2004, American Tower Corporation issued 7.50% senior notes due 2012 in an aggregate principal amount of $225.0 million. The 7.50% senior notes mature on May 1, 2012 and interest is payable semi-annually in arrears on May 1 and November 1 each year beginning May 1, 2004. American Tower Corporation may redeem the 7.50% senior notes after May 1, 2008. The initial redemption price on the 7.50% senior notes is 103.750% of the principal amount, subject to a ratable decline after May 1 of the following year to 100% of the principal amount in 2010 and thereafter. American Tower Corporation may also redeem up to 35% of the 7.50% senior notes any time prior to February 1, 2007 (at a price equal to 107.50% of the principal amount of the notes plus accrued and unpaid interest, if any), with the net cash proceeds of certain public equity offerings within sixty days after the closing of any such offering. The 7.50% senior notes rank equally with the 5.0% convertible notes and the 9³/8% senior notes and are structurally and effectively junior to indebtedness outstanding under the credit facilities, the ATI 12.25% senior subordinated discount notes and the ATI 7.25% senior subordinated notes. The indenture for the 7.50% senior notes contains certain covenants that restrict American Tower Corporation’s ability to incur more debt; guarantee indebtedness; issue preferred stock; pay dividends; make certain investments; merge, consolidate or sell assets; enter into transactions with affiliates; and enter into sale leaseback transactions.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of the material United States federal income tax consequences of the exchange of old notes for new notes and of the ownership and disposition of the new notes. This summary is based on the Internal Revenue Code of 1986, as amended, which we refer to as the “Code”, administrative pronouncements, judicial decisions and final, temporary and proposed regulations, all of which are subject to change. Any change could be applied retroactively in a way that could cause the tax consequences to differ from the consequences described below, possibly with adverse effect.

This summary applies only to persons who hold the old notes and the new notes as capital assets within the meaning of Section 1221 of the Code, that is, for investment purposes. This summary does not discuss all aspects of United States federal income taxation that may be relevant to holders in light of their special circumstances or that may be relevant to holders subject to special tax rules. Special rules apply, for example, to banks, thrifts, and other financial institutions, insurance companies, tax-exempt organizations, regulated investment companies, real estate investment trusts or real estate mortgage investment conduits, financial asset securitization investment trusts, dealers in securities or currencies, persons who hold the notes through a partnership or other pass-through entity, persons subject to alternative minimum tax, persons holding the notes as a part of a hedge, straddle, conversion, constructive sale or other integrated transaction, persons whose functional currency is not the U.S. dollar, or persons who have ceased to be U.S. citizens or to be taxed as resident aliens. This summary also does not discuss any tax consequences arising under the United States federal estate and gift tax laws or the laws of any state, local, foreign or other taxing jurisdiction.

You should consult your own tax advisor concerning the United States federal income tax consequences to you, in light of your particular situation, of the exchange of the old notes for the new notes and the ownership and disposition of the new notes, as well as any consequences arising under United States federal estate and gift tax laws and the laws of any state, local, foreign or other taxing jurisdiction.

As used this summary, the term “U.S. holder” means a beneficial owner of a note that is for United States federal income tax purposes:

•

a citizen or resident of the United States;

•

a corporation (including an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or of any political subdivision thereof;

•

an estate, the income of which is subject to United States federal income tax regardless of its source; or

•

a trust, if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or if a valid election is in place to treat the trust as a United States person.

As used in this summary, the term “non-U.S. holder” means a beneficial owner of a note that is not a U.S. holder.

Tax Consequences to U.S. Holders

Exchange Offer

The exchange of the old notes for the new notes in connection with the exchange offer will not be a taxable sale or exchange. Accordingly:

•

holders will not recognize taxable gain or loss as a result of the exchange;

•

the adjusted tax basis of a new note immediately after the exchange will be the same as the adjusted tax basis of the old note exchanged therefor immediately before the exchange;

•

the holding period of the new note will include the holding period of the old note;

•

the issue price of the new note will equal the issue price of the old note; and

•

any market discount or bond premium applicable to the old notes will carry over to the new notes.

Payments of Interest

Stated interest on a note will be included in a U.S. holder’s gross income as ordinary interest income at the time it is received or accrued, depending on the holder’s method of accounting for United States federal income tax purposes.

Market Discount

If a holder acquires a new note, or purchased an old note which the holder exchanges for a new note, for an amount that is less than its stated redemption price at maturity, the difference will be treated as “market discount,” unless the difference is less than a statutorily defined de minimis amount, and the new note will be subject to the market discount rules. The holder of a new note that is subject to the market discount rules will be required to treat any full or partial principal payment or any gain recognized on the maturity, sale or other disposition of the note as ordinary income, to the extent that the gain does not exceed the accrued market discount on the note. The amount of market discount treated as having accrued will be determined either:

•

on a straight-line basis by multiplying the market discount times a fraction, the numerator of which is the number of days the note was held by the holder and the denominator of which is the total number of days after the date the holder acquired the note up to, and including, the note’s maturity date, or

•

if the holder so elects, on the basis of a constant rate of compound interest.

The holder of a new note subject to the market discount rules may elect to include market discount in income currently, through the use of either the straight-line inclusion method or the elective constant interest rate method, in lieu of recharacterizing gain upon disposition as ordinary income to the extent of accrued market discount at the time of disposition. Once made, this election will apply to all debt instruments with market discount acquired by the electing holder on or after the first day of the first taxable year to which the election applies and may not be revoked without the consent of the IRS. If an election is made to include market discount on a debt instrument in income currently, the basis of the debt instrument in the hands of the holder will be increased by the market discount thereon as it is included in income.

A holder that does not elect to include the market discount on a new note in income currently may be required to defer interest expense deductions for a portion of the interest paid on indebtedness incurred or continued to purchase or carry the note, until the maturity of the note, its earlier disposition in a taxable transaction or, if the holder so elects, a subsequent taxable year in which sufficient income exists with respect to the new note.

Amortizable Bond Premium

If a holder purchases a note for an amount in excess of all amounts payable on the note after the purchase date, other than payments of stated interest, the excess will constitute bond premium. In general, a holder may elect to amortize bond premium by offsetting stated interest allocable to an accrual period with the premium allocable to that period at the time that the holder takes the interest into account under the holder’s regular method of accounting for U.S. federal income tax purposes. Bond premium is allocable to an accrual period on a constant yield basis. Because the notes are redeemable at our option on or after December 1, 2007 and we have the option to redeem a portion of the notes prior to December 1, 2006 from the proceeds of an equity offering (see “Description of Notes—Optional Redemption”), special rules will apply which require a holder to determine the yield and maturity of a note for purposes of calculating and amortizing bond premium by assuming that we will exercise our option to redeem the holder’s note in a manner that maximizes the holder’s yield. If we do not

exercise our option to redeem the note in the manner assumed, then solely for purposes of calculating and amortizing any remaining bond premium, the holder must treat the note as retired and reissued on the deemed redemption date for its adjusted acquisition price as of that date. The adjusted acquisition price of the note is the holder’s initial investment in the note, decreased by the amount of any payments, other than qualified stated interest payments, received with respect to such note and any bond premium previously amortized by the holder.

Once made, the election to amortize bond premium on a constant yield method applies to all debt instruments (other than debt instruments the interest on which is excludable from gross income) held or subsequently acquired by the holder on or after the first day of the first taxable year to which the election applies and may not be revoked without the consent of the IRS.

Sale, Exchange, Retirement or Other Taxable Disposition of the New Notes

A holder of a new note will recognize gain or loss upon the sale, redemption, retirement or other taxable disposition of the note equal to the difference between (a) the amount of cash and the fair market value of any property received (other than amounts representing accrued and unpaid interest) and (b) the holder’s adjusted tax basis in the note. A holder’s adjusted tax basis in a new note generally will equal the cost of the new note or the old note exchanged therefor, increased by any accrued market discount previously included in income and decreased by the amount of any principal payments received with respect to that note and any amortized bond premium.

Subject to the market discount rules discussed above, any gain or loss recognized by a holder on the disposition of a new note generally will be capital gain or loss and will be long-term capital gain or loss if the holder’s holding period is more than one year. For taxable years beginning on or before December 31, 2008, holders who are individuals generally are taxed on long-term capital gains at a maximum marginal rate of 15%, increasing to 20% thereafter. Corporate holders are taxed on long-term capital gains at a maximum marginal rate of 35%. The deductibility of capital losses is subject to limitations.

If a holder sells a note between interest payment dates, a portion of the amount received for the note will reflect accrued interest. The amount is treated as ordinary interest income and not as sale proceeds.

United States Federal Income Tax Consequences to Non-U.S. Holders

The following discussion applies only to non-U.S. holders. This discussion does not address all aspects of United States federal income taxation that may be relevant to non-U.S. holders in light of their special circumstances. For example, special rules may apply to a non-U.S. holder that is a “controlled foreign corporation,” “passive foreign investment company” or “foreign personal holding company,” and those holders should consult their own tax advisors to determine the United States federal, state, local and other tax consequences that may be relevant to them.

Exchange Offer

The exchange of the old notes for the new notes in the exchange offer will not be a taxable sale or exchange for U.S. federal income tax purposes.

Payments of Interest

Subject to the discussion below concerning effectively connected income and backup withholding, payments of interest on the new notes will not be subject to the 30% United States federal withholding tax provided that:

•

the holder does not own actually or constructively 10% or more of the total combined voting power of all classes of our stock entitled to vote;

•

the holder is not a controlled foreign corporation related to us through actual or constructive stock ownership;

•

the holder is not a bank whose receipt of interest on the new notes is described in Section 881(c)(3)(A) of the Code; and

•

either (i) the holder provides the holder’s name and address to us or our paying agent on an IRS Form W-8BEN (or other applicable form) and certifies under penalty of perjury that the holder is not a United States person, or (ii) a financial institution holding the notes on the holder’s behalf certifies to us or our paying agent under penalty of perjury that it has received an IRS Form W-8BEN (or other applicable form) from the beneficial owner and provides a copy or, in the case of certain foreign intermediaries, satisfies other certification requirements under the applicable U.S. Treasury regulations.

Special certification requirements apply to certain non-U.S. holders that are entities rather than individuals.

If a holder cannot satisfy the requirements described above, interest payments made to the holder will be subject to the 30% United States federal withholding tax, unless the holder qualifies for a reduced rate of withholding under a tax treaty or the payments are exempt from withholding because they are effectively connected with the holder’s conduct of a trade or business in the United States (and, where a tax treaty applies, are attributable to a United States permanent establishment maintained by the holder) and the holder satisfies the applicable certification and disclosure requirements. In order to claim a reduction in or exemption from the 30% withholding tax under an applicable tax treaty, a holder must provide a properly executed IRS Form W-8BEN (or a suitable substitute form). In order to claim that interest payments are exempt from the withholding tax because they are effectively connected with the holder’s conduct of a trade or business in the United States, the holder must provide an IRS Form W-8ECI (or a suitable substitute form).

Non-U.S. holders are urged to consult their tax advisors regarding the availability of the above exemptions and the procedure for obtaining such exemptions, if available. A claim for exemption will not be valid if the person receiving the applicable form has actual knowledge or reason to know that the statements on the form are false.

A non-U.S. holder eligible for a reduced rate of United States withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Sale, Exchange, Retirement or Other Taxable Disposition of the New Notes

Subject to the discussion immediately below concerning effectively connected income and backup withholding, a holder generally will not be subject to U.S. federal income tax on any gain, including gain attributable to market discount, realized on the sale, exchange, retirement or other taxable disposition of a new note unless the holder is an individual who is present in the United States for at least 183 days during the year of disposition of the new note and other conditions are satisfied.

Effectively Connected Income

If a holder is engaged in a trade or business in the United States and the holder’s investment in a new note is effectively connected with that trade or business, the holder will be exempt from the 30% withholding tax on interest payments if a certification requirement, generally on IRS Form W-8ECI, is met. In those cases, a holder will instead generally be subject to regular United States federal income tax on a net income basis on any interest payments and gain with respect to the new notes in the same manner as if the holder were a U.S. holder. In addition, if the holder is a foreign corporation, the holder may be subject to a branch profits tax of 30%, or the lower rate provided by an applicable income tax treaty, on the holder’s earnings and profits for the taxable year that are effectively connected with the holder’s conduct of a trade or business in the United States. If a holder is eligible for the benefits of a tax treaty, any effectively connected income or gain will generally be subject to U.S. federal income tax only if it is also attributable to a permanent establishment maintained by the holder in the United States.

Information Reporting and Backup Withholding

Interest payments, payments in respect to principal on, and proceeds received from the sale of, a new note generally will be reported to U.S. holders and to the IRS, and a backup withholding tax may apply to the payments or proceeds if the U.S. holder fails to furnish the payor with a correct taxpayer identification number or other required certification or the holder has been notified by the IRS that the holder is subject to backup withholding for failing to report interest or dividends required to be shown on the holder’s federal income tax returns. Certain U.S. holders, including generally corporations and tax-exempt entities, are exempt from information reporting and backup withholding.

In general, a non-U.S. holder will not be subject to backup withholding with respect to interest or principal payments on the new notes if such holder has provided the statement described above under “—United States Federal Income Tax Consequences to Non-U.S. Holders – Payments of Interest” and the payor does not have actual knowledge or reason to know that such holder is a United States person. Information reporting on IRS Form 1042-S may still apply to interest payments, however. In addition, a non-U.S. holder generally will not be subject to backup withholding or information reporting with respect to the proceeds of the sale of a new note made within the United States or conducted through certain United States financial intermediaries if the payor receives the statement described above and does not have actual knowledge or reason to know that the holder is a United States person or the holder otherwise establishes an exemption. Non-U.S. holders should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of exemptions and the procedure for obtaining those exemptions, if available.

Backup withholding is not an additional tax, and amounts withheld as backup withholding will be allowed as a refund or credit against a holder’s federal income tax liability, as long as the required information is furnished to the IRS.

PLAN OF DISTRIBUTION

Each broker-dealer that receives new notes for its own account in connection with the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of those new notes. A broker-dealer may use this prospectus, as amended or supplemented from time to time, in connection with resales of new notes received in exchange for old notes where the broker-dealer acquired old notes as a result of market-making activities or other trading activities. We have agreed that for a period of 180 days after the expiration date of the exchange offer, we will make available a prospectus, as amended or supplemented, meeting the requirements of the Securities Act to any broker-dealer for use in connection with those resales.

We will not receive any proceeds from any sale of new notes by broker-dealers. Broker-dealers may sell new notes received by them for their own account pursuant to the exchange offer from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the new notes or a combination of those methods of resale, at market prices prevailing at the time of resale, at prices related to prevailing market prices or negotiated prices. Any resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any broker-dealer or the purchasers of any new notes.

Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of those new notes may be deemed to be an “underwriter” within the meaning of the Securities Act. A profit on any resale of those new notes and any commissions or concessions received by any those persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.

For a period of 180 days after the expiration date of the exchange offer, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests these documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer, including the expenses of one counsel for the holders of the old notes, other than commissions or concessions of any brokers or dealers and will indemnify the holders of the old notes, including any broker-dealers, against specified liabilities, including liabilities under the Securities Act.

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

Section 102 of the Delaware General Corporation Law allows a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. The Registrant has included such a provision in Article Sixth of its amended restated certificate of incorporation.

Section 145 of the Delaware General Corporation Law provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances.

Article XII of the Registrant’s By-Laws provides that the Registrant shall indemnify each person who is or was an officer or director of the Registrant to the fullest extent permitted by Section 145 of the Delaware General Corporation Law.

The Registrant has purchased directors’ and officers’ liability insurance which would indemnify its directors and officers against damages arising out of certain kinds of claims which might be made against them based on their negligent acts or omissions while acting in their capacity as such.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

(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.

The Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in this 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.

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 foregoing provisions, 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.

The undersigned registrant hereby undertakes that:

(1) 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 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 declared effective.

(2) 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 the initial bona fide offering thereof.

The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the Prospectus pursuant to Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This undertaking also includes documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
