Other Events and Regulation FD Disclosure.

On May 25, 2004, American Tower Corporation (the “Company”) issued a press release announcing that its operating subsidiaries had successfully refinanced the Company’s previous credit facility with a new $1.1 billion senior secured credit facility, consisting of a $400 million revolving credit facility, a $300 million Term Loan A and a $400 million Term Loan B. The new credit facility is guaranteed by the Company and its subsidiaries and is secured by a pledge of substantially all of the Company’s assets.

At closing, the Company received approximately $685 million of net proceeds from borrowings under the new facility, after deducting related expenses and fees. Approximately $670 million of the net proceeds were used to repay principal and interest on the outstanding borrowings under the Company’s previous credit facility. The Company plans to use the remaining approximately $15 million of net proceeds for general corporate purposes, including refinancing other existing indebtedness. At closing, the Company had approximately $373 million of availability under the revolving loan facility, net of undrawn letters of credit of approximately $27 million.

Among other changes, the new facility extends the maturity dates from 2007 to 2011 for a majority of the borrowings outstanding under the new credit facility, subject to the conditions described below, and permits the Company to use borrowings under the new facility and internally generated funds to repurchase other indebtedness without seeking approval from the lenders under the new facility.

The table below shows the principal amortization schedule under the new credit facility for the outstanding Term Loan A and Term Loan B:


	Payments Due by December 31,
	2004		2005		2006		2007		2008		2009		2010		2011
	(in millions)
Term Loan A	$	0.0	$	0.0	$	22.5	$	52.5	$	60.0	$	60.0	$	82.5	$	22.5
Term Loan B		2.0		4.0		4.0		4.0		4.0		4.0		4.0		374.0

A final payment of all outstanding revolving loans is due in 2011.

Notwithstanding the foregoing, the Term Loan A and any outstanding revolving loans will mature on August 15, 2008 and the Term Loan B will mature on October 31, 2008 if (1) on or prior to August 1, 2008, the Company’s 9 3/8% Senior Notes have not been (a) refinanced with indebtedness of the Company having a maturity date of February 28, 2012 or later or with loans under the new credit facilities, or (b) repaid, prepaid, redeemed, repurchased or otherwise retired; and (2) the Company’s Consolidated Leverage Ratio (Total Parent Debt to Annualized Operating Cash Flow) at June 30, 2008 exceeds 4.50 to 1.00. If this were to occur, the payments due in 2008 for Term Loan A and Term Loan B would be $225.0 million and $386.0 million, respectively.

The new credit facilities contain certain financial ratios and operating covenants and other restrictions (including limitations on additional debt, guaranties, use of proceeds from asset sales, dividends and distributions, investments and liens) with which the Company’s borrower subsidiaries and restricted subsidiaries must comply. The new credit facilities contain four financial maintenance tests with which the Company must comply:

•

a leverage ratio (Total Debt to Annualized Operating Cash Flow) of not greater than 5.50 to 1.00 through June 30, 2005, decreasing to 5.25 to 1.00 at July 1, 2005, to 5.00 to 1.00 at January 1, 2006, to 4.75 to 1.00 at April 1, 2006, to 4.50 to 1.00 at July 1, 2006 and to 4.00 to 1.00 at January 1, 2007 and thereafter;

- 2 -

•

a senior leverage ratio (Senior Debt to Annualized Operating Cash Flow) of not greater than 4.00 to 1.00 through December 31, 2005, decreasing to 3.75 to 1.00 on January 1, 2006, to 3.50 to 1.00 on July 1, 2006 and to 3.00 to 1.00 on January 1, 2007 and thereafter;

•

an interest coverage ratio (Annualized Operating Cash Flow to Interest Expense) of not less than 2.50 to 1.00; and

•

a fixed charge coverage ratio (Annualized Operating Cash Flow to Fixed Charges) of not less than or equal to 1.00 to 1.00.

Any failure to comply with these covenants would not only prevent the Company from being able to borrow additional funds under its revolving line of credit, but would also constitute a default. These covenants also restrict the Company’s ability, as the parent company, to incur any debt other than that currently outstanding, certain refinancings of that debt and outstanding debt of our subsidiaries and certain other exceptions. The credit facilities also limit the Company’s revolving loan drawdowns based on its cash on hand.

As a result of the closing of the new credit facility, the Company may be required to write-off deferred financing fees of up to approximately $12 million associated with its previous credit facilities that have been refinanced.

The foregoing is only a summary of certain provisions of the new facility and is qualified in its entirety by the terms of the new credit facility. Copies of the press release and the new credit facility are filed herewith as Exhibits 99.1 and 99.2, respectively, and are incorporated by reference herein.

Once repaid, Advances under the Term Loan B Commitments may not be reborrowed.

(d) Letters of Credit.

Section 2.2 Manner of Borrowing and Disbursement.

(a) Choice of Interest Rate, Etc. Any Advance hereunder shall, at the option of the requesting Borrower, be made as a Base Rate Advance or a LIBOR Advance; provided, however, that at such time as there shall have occurred and be continuing a Default hereunder, none of the Borrowers shall have the right to receive or Continue a LIBOR Advance or to Convert a Base Rate Advance to a LIBOR Advance. Any notice given to the Administrative Agent in connection with a requested Advance hereunder shall be given to the Administrative Agent prior to 11:00 a.m. (New York, New York time) in order for such Business Day to count toward the minimum number of Business Days required.

(b) Base Rate Advances.

(i) Advances. A Borrower shall give the Administrative Agent in the case of Base Rate Advances at least one (1) Business Day’s irrevocable prior telephonic notice followed immediately by a Request for Advance; provided, however, that such Borrower’s failure to confirm any telephonic notice with a Request for Advance shall not invalidate any notice so given if acted upon by the Administrative Agent. Upon receipt of such notice from a Borrower, the Administrative Agent shall promptly notify each Lender by telephone or telecopy of the contents thereof.

-28-

(ii) Conversions. Any Borrower may, without regard to the applicable Payment Date and upon at least three (3) Business Days’ irrevocable prior telephonic notice followed by a Request for Advance, Convert all or a portion of the principal of a Base Rate Advance to a LIBOR Advance. On the date indicated by the applicable Borrower, such Base Rate Advance shall be so Converted. The failure to give timely notice hereunder with respect to the Payment Date of any Base Rate Advance shall be considered a request for a Base Rate Advance.

(c) LIBOR Advances. Upon request, the Administrative Agent, whose determination in absence of manifest error shall be conclusive, shall determine the available LIBOR Bases and shall notify the requesting Borrower of such LIBOR Bases to apply for the applicable LIBOR Advance.

(i) Advances. A Borrower shall give the Administrative Agent in the case of LIBOR Advances at least three (3) Business Days’ irrevocable prior telephonic notice followed immediately by a Request for Advance; provided, however, that such Borrower’s failure to confirm any telephonic notice with a Request for Advance shall not invalidate any notice so given if acted upon by the Administrative Agent. Upon receipt of such notice from a Borrower, the Administrative Agent shall promptly notify each Lender by telephone or telecopy of the contents thereof.

(ii) Conversions and Continuations. At least three (3) Business Days prior to the Payment Date for each LIBOR Advance, the applicable Borrower shall give the Administrative Agent telephonic notice followed by written notice specifying whether all or a portion of such LIBOR Advance (A) is to be Continued in whole or in part as one or more LIBOR Advances, (B) is to be Converted in whole or in part to a Base Rate Advance, or (C) is to be repaid. The failure to give such notice shall preclude the Borrowers from Continuing such Advance as a LIBOR Advance on its Payment Date and shall be considered a request to Convert such Advance to a Base Rate Advance. Upon such Payment Date such LIBOR Advance will, subject to the provisions hereof, be so Continued, Converted or repaid, as applicable.

(d) Notification of Lenders. Upon receipt of irrevocable prior telephonic notice in accordance with Section 2.2(b) or (c) hereof or a Request for Advance, or a notice of Conversion or Continuation from a Borrower with respect to any outstanding Advance prior to the Payment Date for such Advance, the Administrative Agent shall promptly but no later than the close of business on the day of such notice notify each Lender having the applicable Commitment by telephone, followed promptly by written notice or telecopy, of the contents thereof and the amount of such Lender’s portion of the Advance. Each Lender having the applicable Commitment shall, not later than 12:00 noon (New York, New York time) on the date of borrowing specified in such notice, make available to the Administrative Agent at the Administrative Agent’s Office, or at such account as the Administrative Agent shall designate, the amount of its portion of any Advance that represents an additional borrowing hereunder in immediately available funds.

-29-

(e) Disbursement.

(i) Prior to 2:00 p.m. (New York, New York time) on the date of an Advance hereunder, the Administrative Agent shall, subject to the satisfaction of the conditions set forth in Article 3 hereof, disburse the amounts made available to the Administrative Agent by the Lenders in like funds by (A) transferring the amounts so made available by wire transfer pursuant to the requesting Borrower’s instructions, or (B) in the absence of such instructions, crediting the amounts so made available to the account of the requesting Borrower maintained with the Administrative Agent.

(ii) Unless the Administrative Agent shall have received notice from a Lender having an applicable Commitment prior to 12:00 noon (New York, New York time) on the date of any Advance that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Advance, the Administrative Agent may assume that such Lender has made or will make such portion available to the Administrative Agent on the date of such Advance and the Administrative Agent may in its sole discretion and in reliance upon such assumption, make available to the requesting Borrower on such date a corresponding amount. If and to the extent an applicable Lender does not make such ratable portion available to the Administrative Agent, such Lender agrees to repay to the Administrative Agent on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the requesting Borrower until the date such amount is repaid to the Administrative Agent, at the Federal Funds Rate.

(iii) If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s portion of the applicable Advance for purposes of this Agreement. If such Lender does not repay such corresponding amount immediately upon the Administrative Agent’s demand therefor, the Administrative Agent shall notify the Borrowers, and the Borrowers shall immediately pay such corresponding amount to the Administrative Agent, with interest at the Federal Funds Rate. The failure of any Lender to fund its portion of any Advance shall not relieve any other Lender of its obligation, if any, hereunder to fund its respective portion of the Advance on the date of such borrowing, but no Lender shall be responsible for any such failure of any other Lender.

(iv) In the event that, at any time when there is no Default and each of the conditions in Section 3.2 hereof has been satisfied, a Lender having an applicable Commitment for any reason fails or refuses to fund its portion of an Advance and such failure shall continue for a period in excess of thirty (30) days, then, until such time as such Lender has funded its portion of such Advance (which late funding shall not absolve such Lender from any liability it may have to the Borrowers), or all other Lenders have received payment in full from the Borrowers (whether by repayment or prepayment) or otherwise of the principal and interest due in respect of such Advance, such non-funding

-30-

Lender shall not have the right (A) to vote regarding any issue on which voting is required or advisable under this Agreement or any other Loan Document, and such Lender’s portion of the applicable Loans shall not be counted as outstanding for purposes of determining “Majority Lenders” hereunder, and (B) to receive payments of principal, interest or fees from the Borrowers, the Administrative Agent or the other Lenders in respect of its portion of the applicable Loans until all applicable Loans of the other Lenders have been fully paid.

Section 2.3 Interest.

(a) On Base Rate Advances. Interest on each Base Rate Advance shall be computed on the basis of a year of 365/366 days for the actual number of days elapsed and shall be payable at the Base Rate Basis for such Advance, in arrears on the applicable Payment Date. Interest on Base Rate Advances then outstanding shall also be due and payable on the Maturity Date.

(b) On LIBOR Advances. Interest on each LIBOR Advance shall be computed on the basis of a 360-day year for the actual number of days elapsed and shall be payable at the LIBOR Basis for such Advance, in arrears on the applicable Payment Date, and, in addition, if the Interest Period for a LIBOR Advance exceeds three (3) months, interest on such LIBOR Advance shall also be due and payable in arrears on every three (3) month anniversary of the beginning of such Interest Period. Interest on LIBOR Advances then outstanding shall also be due and payable on the Maturity Date.

(c) Interest If No Notice of Selection of Interest Rate Basis. If a Borrower fails to give the Administrative Agent timely notice of its selection of a LIBOR Basis, or if for any reason a determination of a LIBOR Basis for any Advance is not timely concluded, the Base Rate Basis shall apply to such Advance.

(d) Interest Upon Event of Default. Immediately upon the occurrence of an Event of Default hereunder, the outstanding principal balance of the Loans shall bear interest at the Default Rate. Such interest shall be payable on demand by the Majority Lenders and shall accrue until the earlier of (i) waiver or cure of the applicable Event of Default, (ii) agreement by the Majority Lenders (or, if applicable to the underlying Event of Default, the Lenders) to rescind the charging of interest at the Default Rate or (iii) payment in full of the Obligations.

(e) LIBOR Contracts. At no time may the number of outstanding LIBOR Advances hereunder exceed twelve (12).

At any time after the aggregate Unreinvested Net Proceeds from all sales, transfers or other dispositions of assets of the Borrowers and their Restricted Subsidiaries, or from any insurance or condemnation proceeding in respect of such assets after the Agreement Date exceeds $10,000,000.00, the Revolving Loan Commitments shall be automatically and permanently reduced by an amount equal to the repayment of the Revolving Loans required under Section 2.7(b)(iv) hereof; provided, however, that if there are no Loans then outstanding, or if the Unreinvested Net Proceeds exceeds the Loans then outstanding, the Revolving Loan Commitments shall be reduced on a pro rata basis by an aggregate amount equal to such Unreinvested Net Proceeds, or the excess of such Unreinvested Net Proceeds over the Loans, as applicable, regardless of any repayment of the Revolving Loans.

Each Lender which opens such a loan account shall debit such loan account for the principal amount of its portion of each Advance made by it and accrued interest thereon, and shall credit such loan account for each payment on account of principal of or interest on its Loans. The records of a Lender with respect to the loan account maintained by it shall be prima facie evidence of its portion of the Loans and accrued interest thereon absent manifest error, but the failure of any Lender to make any such notations or any error or mistake in such notations shall not affect the Borrowers’ repayment obligations with respect to such Loans.

Section 2.9 Manner of Payment.

(a) Each payment (including, without limitation, any prepayment) by the Borrowers on account of the principal of or interest on the Loans, commitment fees and any other amount owed to the Lenders or the Administrative Agent or any of them under this Agreement or the Notes shall be made not later than 1:00 p.m. (New York, New York time) on the date specified for payment under this Agreement to the Administrative Agent at the Administrative Agent’s Office, for the account of the Lenders or the Administrative Agent, as the case may be, in lawful money of the United States of America in immediately available funds. Any payment received by the Administrative Agent after 1:00 p.m. (New York, New York time) shall be deemed received on the next Business Day. Receipt by the Administrative Agent of any payment intended for any Lender or Lenders hereunder prior to 1:00 p.m. (New York, New York time) on any Business Day shall be deemed to constitute receipt by such

-37-

Lender or Lenders on such Business Day. In the case of a payment for the account of a Lender, the Administrative Agent will promptly, but no later than the close of business on the date such payment is deemed received, thereafter distribute the amount so received in like funds to such Lender. If the Administrative Agent shall not have received any payment from the Borrowers as and when due, the Administrative Agent will promptly notify the applicable Lenders accordingly. In the event that the Administrative Agent shall fail to make distribution to any Lender as required under this Section 2.9, the Administrative Agent agrees to pay such Lender interest from the date such payment was due until paid at the Federal Funds Rate.

(b) The Borrowers agree to pay, on a joint and several basis (subject to the provisions of Section 11.20 hereof), principal, interest, fees and all other amounts due hereunder or under the Notes without set-off or counterclaim or any deduction whatsoever.

(c) Prior to the acceleration of the Loans under Section 8.2 hereof, if some but less than all amounts due from the Borrowers are received by the Administrative Agent with respect to the Obligations, the Administrative Agent shall distribute such amounts in the following order of priority, all on a pro rata basis to the Lenders: (i) to the payment on a pro rata basis of any fees or expenses then due and payable to the Administrative Agent and the Issuing Bank, or any of them or expenses then due and payable to the Lenders; (ii) to the payment of interest then due and payable on the Loans on a pro rata basis and of fees then due and payable to the Lenders on a pro rata basis; (iii) to the payment of all other amounts not otherwise referred to in this Section 2.9(c) then due and payable to the Administrative Agent, the Issuing Bank and the Lenders, or any of them, hereunder or under the Notes or any other Loan Document; and (iv) to the payment of principal then due and payable on the Loans on a pro rata basis.

(d) Subject to any contrary provisions in the definition of Interest Period, if any payment under this Agreement or any of the other Loan Documents is specified to be made on a day which is not a Business Day, it shall be made on the next Business Day, and such extension of time shall in such case be included in computing interest and fees, if any, in connection with such payment.

(e) Each Registered Noteholder (or, if such Registered Noteholder is not the beneficial owner thereof, such beneficial owner) shall deliver to the Borrowers (with a copy to the Administrative Agent) prior to or at the time it becomes a Registered Noteholder, an Internal Revenue Service Form W-8BEN or W-8ECI (or such successor and related forms as may from time to time be adopted by the relevant taxing authorities of the United States of America), together with an annual certificate stating that such Registered Noteholder or beneficial owner, as the case may be, is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and is not otherwise described in Section 881(c)(3) of the Code. Each Registered Noteholder or beneficial owner, as the case may be, shall promptly notify the Borrowers (with a copy to the Administrative Agent) if at any time, such Registered Noteholder or beneficial owner, as the case may be, determines that it is no longer in a position to make the certification made in such certificate to the Borrowers (or any other form of certification adopted by the relevant taxing authorities of the United States of America for such purposes).

Section 2.10 Reimbursement.

(a) Whenever any Lender shall sustain or incur any losses or reasonable out-of-pocket expenses in connection with (i) the failure by a Borrower to borrow, Continue or Convert any LIBOR Advance after having given notice of its intention to borrow, Continue or Convert such Advance in accordance with Section 2.2 hereof (whether by reason of such Borrower’s election not to proceed or the non-fulfillment of any of the conditions set forth in Article 3 hereof), or (ii) the prepayment other than on the applicable Payment Date (or failure to prepay after giving notice thereof) of any LIBOR Advance in whole or in part for any reason, the Borrowers agree to pay, on a joint and several basis, to such Lender, upon such Lender’s demand, an amount sufficient to compensate such Lender for all such losses and out-of-pocket expenses. Such Lender’s good faith determination of the amount of such losses or out-of-pocket expenses, as set forth in writing and accompanied by calculations in reasonable detail demonstrating the basis for its demand, shall be presumptively correct absent manifest error.

(b) Losses subject to reimbursement hereunder shall include, without limiting the generality of the foregoing, lost margins, expenses incurred by any Lender or any participant of such Lender permitted hereunder in connection with the re-employment of funds prepaid, paid, repaid, not borrowed, or not paid, as the case may be, and will be payable whether the applicable Maturity Date is changed by virtue of an amendment hereto (unless such amendment expressly waives such payment) or as a result of acceleration of the Loans.

Section 2.11 Pro Rata Treatment.

(a) Advances. Each Advance under the Revolving Loan Commitments from the Lenders hereunder shall be made pro rata on the basis of the applicable Commitment Ratios of the Lenders having a Revolving Loan Commitment.

(b) Payments. Each payment and, except as provided in Section 2.7(a), prepayment of principal of the Loans, and, except as provided in Section 2.2(e) hereof and Article 10 hereof, each payment of interest on the Loans, shall be made to the Lenders pro rata on the basis of their respective unpaid principal amounts outstanding under the applicable Loans immediately prior to such payment or prepayment. If any Lender shall obtain any payment (whether involuntary, through the exercise of any right of set-off, or otherwise) on account of the Loans in excess of its ratable share of the Loans under its applicable Commitment Ratio, such Lender shall forthwith purchase from the other Lenders such participations in the portion of the applicable Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and each such other Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery. The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.11(b) may, to the fullest extent permitted by law, exercise all its rights of payment (including, without limitation, the right of set-off) with respect to such participation as fully as if such purchasing Lender were the direct creditor of the Borrowers in the amount of such participation.

-39-

(c) Commitment Reductions. Any reduction of the Revolving Loan Commitments required or permitted hereunder shall reduce the Revolving Loan Commitment of each Lender having a Revolving Loan Commitment on a pro rata basis based on the Commitment Ratio of such Lender for such Revolving Loan Commitment.

Section 2.12 Capital Adequacy. If after the date hereof, the adoption of any Applicable Law regarding the capital adequacy of banks or bank holding companies, or any change in Applicable Law (whether adopted before or after the Agreement Date) or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Lender (or the bank holding company of such Lender) with any directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on any Lender’s capital as a consequence of its obligations hereunder with respect to the Loans and the Commitments to a level below that which it could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s policies with respect to capital adequacy immediately before such adoption, change or compliance and assuming that such Lender’s (or the bank holding company of such Lender) capital was fully utilized prior to such adoption, change or compliance) by an amount reasonably deemed by such Lender to be material, then, upon demand by such Lender, the Borrowers shall promptly pay, on a joint and several basis, to such Lender such additional amounts as shall be sufficient to compensate such Lender (on an after-tax basis) for such reduced return, together with interest on such amount from the fourth (4th) Business Day after the date of demand or the applicable Maturity Date, as applicable, until payment in full thereof at the Default Rate. A certificate of such Lender setting forth the amount to be paid to such Lender by the Borrowers as a result of any event referred to in this paragraph and supporting calculations in reasonable detail shall be presumptively correct absent manifest error.

Section 2.13 Lender Tax Forms. On or prior to the Agreement Date and, to the extent permitted by applicable U.S. Federal law, on or prior to the first Business Day of each calendar year thereafter, each Lender which is organized in a jurisdiction other than the United States shall provide each of the Administrative Agent and the Borrowers (a) if such Lender is a “bank” under Section 881(c)(3)(A) of the Code, with a properly executed original of Internal Revenue Service Form W-8BEN or W-8ECI (or any successor form) prescribed by the Internal Revenue Service or other documents satisfactory to the Borrowers and the Administrative Agent, or with a properly executed Internal Revenue Service Form W-9, as the case may be, certifying (i) as to such Lender’s status as exempt from United States withholding taxes with respect to all payments to be made to such Lender hereunder and under the Notes or (ii) that all payments to be made to such Lender hereunder and under the Notes are subject to such taxes at a rate reduced to zero by an applicable tax treaty, or (b) if such Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and intends to claim exemption from U.S. Federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest”, a Form W-8BEN, or any subsequent versions thereof or successors thereto (and, if such Lender delivers a Form W-8BEN, a certificate representing that such Lender is not a bank for purposes of Section 881(c) of the Code, is not a ten-percent (10%) shareholder (within the meaning of Section 871(h)(3)(B) of the Code and is not a controlled foreign corporation related to the Borrowers (within the meaning of Section 864(d)(4) of the Code)), properly completed and duly

-40-

executed by such Lender, indicating that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes as permitted by the Code. To the extent permitted by applicable U.S. Federal law, each such Lender agrees to provide the Administrative Agent and the Borrowers with new forms prescribed by the Internal Revenue Service upon the expiration or obsolescence of any previously delivered form, or after the occurrence of any event requiring a change in the most recent forms delivered by it to the Administrative Agent and the Borrowers.

Section 2.14 Letters of Credit.

(a) Subject to the terms and conditions hereof, the Issuing Bank, on behalf of the Lenders having a Revolving Loan Commitment, and in reliance on the agreements of such Lenders set forth in Section 2.14(d) hereof, hereby agrees to issue one or more Letters of Credit up to an aggregate face amount equal to the Available Letter of Credit Commitment determined immediately prior to giving effect to the issuance thereof; provided, however, that the Issuing Bank shall not issue any Letter of Credit (i) unless the conditions precedent to the issuance thereof set forth in Section 3.3 hereof have been satisfied, (ii) if any Default then exists or would be caused thereby, (iii) if, after giving effect to such issuance, the Available Revolving Loan Commitment would be less than zero or (iv) within thirty (30) days preceding the Revolving Loan Maturity Date; and provided further, however, that at no time shall the aggregate amount of the Letter of Credit Obligations outstanding hereunder exceed $50,000,000.00. Each Letter of Credit shall (A) be payable at sight, (B) be denominated in United States dollars, (C) expire, (i) with respect to Standby Letters of Credit, no later than the earlier to occur of (x) the fifth Business Day preceding the Revolving Loan Maturity Date and (y) 360 days after its date of issuance (but may contain provisions for automatic renewal provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal), and (ii) with respect to Commercial Letters of Credit, no later than the earlier to occur of (x) the thirtieth day preceding the Revolving Loan Maturity Date and (y) 180 days after its date of Issuance (but may contain provisions for automatic renewal provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal). Each Letter of Credit shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 and, to the extent not inconsistent therewith, the laws of the State of New York. The Issuing Bank shall not at any time be obligated to issue, or cause to be issued, any Letter of Credit if such issuance would conflict with, or cause the Issuing Bank to exceed any limits imposed by, any Applicable Law. If a Letter of Credit provides that it is automatically renewable unless notice is given by the Issuing Bank that it will not be renewed, the Issuing Bank shall not be bound to give a notice of non-renewal unless directed to do so by Lenders having in the aggregate at least fifty-one percent (51%) of the Revolving Loan Commitment at least sixty-five (65) days prior to the then scheduled expiration date of such Letter of Credit. It is hereby agreed that the Letters of Credit set forth on Schedule 2 attached hereto are Letters of Credit issued hereunder for all purposes hereunder notwithstanding anything herein that may be construed to the contrary.

(b) Any Borrower may from time to time request the Issuing Bank to issue Letters of Credit. The Borrower shall execute and deliver to the Administrative Agent and the Issuing Bank a Request for Issuance of Letter of Credit for each Letter of Credit to be issued by the Issuing Bank not later than 12:00 noon (New York, New York time) on the fifth (5th)

-41-

Business Day preceding the date on which the requested Letter of Credit requested is to be issued, or such shorter notice as may be acceptable to the Issuing Bank and the Administrative Agent. Upon receipt of any such Request for Issuance of Letter of Credit, subject to satisfaction of all conditions precedent thereto as set forth in Section 3.3 hereof, the Issuing Bank shall process such Request for Issuance of Letter of Credit and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby. The Issuing Bank shall furnish a copy of such Letter of Credit (or any amendment thereto or renewal or extension thereof) to the Borrowers, the Administrative Agent and each of the Lenders following the issuance thereof. The Borrower shall pay or reimburse the Issuing Bank for normal and customary costs and expenses incurred by the Issuing Bank in issuing, effecting payment under, amending or otherwise administering the Letters of Credit.

(c) At such time as the Administrative Agent shall be notified by the Issuing Bank that the beneficiary under any Letter of Credit has drawn on the same, the Administrative Agent shall promptly notify the Borrowers and each Lender having a Revolving Loan Commitment, by telephonic notice, followed promptly by written notice, of the amount of the draw and, in the case of each such Lender, such Lender’s portion of such draw amount as calculated in accordance with its respective Commitment Ratio under the Revolving Loan Commitment.

(d) The Borrowers hereby agree to immediately reimburse the Issuing Bank for amounts paid by the Issuing Bank in respect of draws under a Letter of Credit issued at a Borrower’s request. In order to facilitate such repayment, the Borrowers hereby irrevocably request the Lenders having a Revolving Loan Commitment, and such Lenders hereby severally agree, on the terms and conditions of this Agreement (other than as provided in Article 2 hereof with respect to the amounts of, the timing of requests for, and the repayment of Advances hereunder and in Article 3 hereof with respect to conditions precedent to Advances hereunder), with respect to any honoring of any draw under a Letter of Credit prior to the occurrence of an Event of Default under Section 8.1(f) or (g) hereof, to make an Advance (which Advance may be a LIBOR Advance if the Borrowers so request in a timely manner or may be Converted to a LIBOR Advance as provided in the Loan Agreement) to the Borrowers on each day on which the Issuing Bank honors a draw is made under any Letter of Credit and in the amount of such draw, and to pay the proceeds of such Advance directly to the Issuing Bank to reimburse the Issuing Bank for the amount paid by it upon such draw. Each Lender having a Revolving Loan Commitment shall pay its share of such Advance by paying its portion of such Advance to the Administrative Agent in accordance with Section 2.2(e) hereof and its respective Commitment Ratio under the Revolving Loan Commitments, without reduction for any set-off or counterclaim of any nature whatsoever and regardless of whether any Default or Event of Default (other than with respect to an Event of Default under Section 8.1(f) or (g) hereof) then exists or would be caused thereby. If at any time that any Letters of Credit are outstanding, any of the events described in clauses of Section 8.1(f) or (g) hereof shall have occurred and be continuing, then each Lender having

-42-

a Revolving Loan Commitment shall, automatically upon the occurrence of any such event and without any action on the part of the Issuing Bank, the Borrowers, the Administrative Agent or such Lenders, be deemed to have purchased an undivided participation in the face amount of all Letters of Credit then outstanding in an amount equal to such Lender’s respective Commitment Ratio under the Revolving Loan Commitments, and each Lender having a Revolving Loan Commitment shall, notwithstanding such Event of Default, upon a drawing being honored under any Letter of Credit, immediately pay to the Administrative Agent for the account of the Issuing Bank, in immediately available funds, the amount of such Lender’s participation (and the Issuing Bank shall deliver to such Lender a loan participation certificate dated the date of the occurrence of such event and in the amount of such Lender’s respective Commitment Ratio under the Revolving Loan Commitments). The disbursement of funds in connection with a draw under a Letter of Credit pursuant to this Section 2.14(d) shall be subject to the terms and conditions of Section 2.2(e) hereof. The obligation of each Lender having a Revolving Loan Commitment to make payments to the Administrative Agent, for the account of the Issuing Bank, in accordance with this Section 2.14 shall be absolute and unconditional and no such Lender shall be relieved of its obligations to make such payments by reason of noncompliance by any other Person with the terms of the Letter of Credit or for any other reason. The Administrative Agent shall promptly remit to the Issuing Bank the amounts so received from the other Lenders. Any overdue amounts payable by the Lenders having a Revolving Loan Commitment to the Issuing Bank in respect of a draw under any Letter of Credit shall bear interest, payable on demand, at the rate on overnight federal funds transactions with members of the Federal Reserve System arranged by federal funds brokers, as published for such day by the Federal Reserve Bank of New York.

(e) The Borrowers agree that any action taken or omitted to be taken by the Issuing Bank in connection with any Letter of Credit, except for such actions or omissions as shall constitute gross negligence or willful misconduct on the part of the Issuing Bank, shall be binding on the Borrowers as between the Borrowers and the Issuing Bank, and shall not result in any liability of the Issuing Bank to the Borrowers. The obligation of the Borrowers to reimburse the Lenders for Advances made to reimburse the Issuing Bank for draws under the Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Loan Document;

(ii) any amendment or waiver of or consent to any departure from any or all of the Loan Documents;

(iii) any improper use which may be made of any Letter of Credit or any improper acts or omissions of any beneficiary or transferee of any Letter of Credit in connection therewith;

(iv) the existence of any claim, set-off, defense or any right which the Borrowers may have at any time against any beneficiary or any transferee of any Letter of Credit (or Persons for whom any such beneficiary or any such transferee may be acting) or any Lender (other than the defense of payment to such Lender in accordance with the terms of this Agreement) or any other Person, whether in connection with any Letter of Credit, any transaction contemplated by any Letter of Credit, this Agreement, any other Loan Document, or any unrelated transaction;

-43-

(v) any statement or any other documents presented under any Letter of Credit proving to be insufficient, forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever, provided that the same shall not have resulted from gross negligence or willful misconduct of the Issuing Bank;

(vi) the insolvency of any Person issuing any documents in connection with any Letter of Credit;

(vii) any breach of any agreement between the Borrowers and any beneficiary or transferee of any Letter of Credit, provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(viii) any irregularity in the transaction with respect to which any Letter of Credit is issued, including any fraud by the beneficiary or any transferee of such Letter of Credit, provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(ix) any errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, wireless or otherwise, whether or not they are in code, provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(x) any act, error, neglect or default, omission, insolvency or failure of business of any of the correspondents of the Issuing Bank, provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(xi) any other circumstances arising from causes beyond the control of the Issuing Bank;

(xii) payment by the Issuing Bank under any Letter of Credit against presentation of a sight draft or a certificate which does not comply with the terms of such Letter of Credit, provided that the same shall not have resulted from gross negligence or willful misconduct of the Issuing Bank; and

(xiii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, provided that the same shall not have resulted from the result of gross negligence or willful misconduct of the Issuing Bank or any other Lender.

(f) If any change in Applicable Law, any change in the interpretation or administration thereof, or any change in compliance with Applicable Law by the Issuing Bank or any Lender having a Revolving Loan Commitment as a result of any official request or directive of any governmental authority, central bank or comparable agency (whether or not having the force of law) shall (i) impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System),

-44-

special deposit, capital adequacy, assessment or other requirements or conditions against Letters of Credit issued by the Issuing Bank or against participations by any other Lender in the Letters of Credit or (ii) impose on the Issuing Bank or any other Lender any other condition regarding any Letter of Credit or any participation therein, and the result of any of the foregoing in the reasonable determination of the Issuing Bank or such Lender, as the case may be, is to increase the cost to the Issuing Bank or such Lender of issuing or maintaining any Letter of Credit or purchasing or maintaining any participation therein, as the case may be, by an amount (which amount shall be reasonably determined) deemed by the Issuing Bank or such Lender to be material, and the designation of a different lending office will not avoid the need for additional compensation (without creating other unreimbursed costs or disadvantage to such Lender), then, on request by the Issuing Bank or such Lender, the Borrower shall pay, within ten (10) days after demand, the Issuing Bank or such Lender, as the case may be, such additional amount or amounts as the Issuing Bank or such Lender, as the case may be, so determines will compensate it on an after-tax basis for such increased costs. A certificate of the Issuing Bank or such Lender setting forth the amount, and in reasonable detail the basis for the Issuing Bank or such Lender’s determination of such amount, to be paid to the Issuing Bank or such Lender by the Borrower as a result of any event referred to in this paragraph shall, absent manifest error, be conclusive.

(g) Each Lender having a Revolving Loan Commitment shall be responsible for its pro rata share (based on such Lender’s respective Commitment Ratio under the Revolving Loan Commitments) of any and all reasonable out-of-pocket costs, expenses (including reasonable legal fees) and disbursements which may be incurred or made by the Issuing Bank in connection with the collection of any amounts due under, the administration of, or the presentation or enforcement of any rights conferred by any Letter of Credit, the Borrowers’ or any guarantor’s obligations to reimburse or otherwise. In the event the Borrowers shall fail to pay such expenses of the Issuing Bank within ten (10) days after demand for payment by the Issuing Bank, each Lender having a Revolving Loan Commitment shall thereupon pay to the Issuing Bank its pro rata share (based on such Lender’s respective Commitment Ratio under the Revolving Loan Commitments) of such expenses within five (5) days from the date of the Issuing Bank’s notice to the Lenders having a Revolving Loan Commitment of the Borrowers’ failure to pay; provided, however, that if the Borrowers or any guarantor shall thereafter pay such expense, the Issuing Bank will repay to each Lender having a Revolving Loan Commitment the amounts received from such Lender hereunder.

(h) The Borrowers agree that each Advance by the Lenders having Revolving Loan Commitments to reimburse the Issuing Bank for draws under any Letter of Credit, shall, for all purposes hereunder, be deemed to be an Advance under the Revolving Loan Commitment to the Borrowers and shall be payable and bear interest in accordance with all other Revolving Loans to the Borrowers.

(i) The Borrowers will indemnify and hold harmless the Administrative Agent, the Issuing Bank and each Lender and each of the foregoing Person’s respective employees, representatives, officers and directors from and against any and all claims, liabilities, obligations, losses (other than loss of profits), damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys’ fees, but excluding taxes) which may be imposed on, incurred by or asserted against the Administrative Agent, the Issuing Bank or any such other Lender in any way relating to or

-45-

arising out of the issuance of a Letter of Credit, except that the Borrowers shall not be liable to the Administrative Agent, the Issuing Bank or any such Lender for any portion of such claims, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, or disbursements resulting from the gross negligence or willful misconduct of the Person seeking indemnification as determined by a non-appealable judicial order. This Section 2.14(i) shall survive termination of this Agreement.

Section 2.15 Incremental Facility Advances.

(a) Subject to the terms and conditions of this Agreement, the Borrowers may request an Incremental Facility Commitment (which may be in the form of a revolver (to the extent such Incremental Facility Commitment is a Refinancing Incremental Facility (as defined below) of the Revolving Loan Commitment) or a term loan) on any Business Day; provided, however, that (i) the Borrowers may not request any Incremental Facility Commitment or an Incremental Facility Advance after the occurrence and during the continuance of a Default or an Event of Default, including, without limitation, any Event of Default that would result after giving effect to any Incremental Facility Advance, (ii) the aggregate amount of any Incremental Facilities, the proceeds of which do not refinance the Loans (a “Non-Refinancing Incremental Facility”), shall not exceed $500,000,000.00 and (iii) the aggregate amount of Incremental Facilities the entire net proceeds of which are used to refinance all or any portion of the Loans or the Revolving Loan Commitment shall be unlimited (a “Refinancing Incremental Facility”), provided that the amount of any Refinancing Incremental Facility shall be limited to the principal amount, accrued interest, fees and premiums payable with respect to the Loans or Revolving Loan Commitment being refinanced, the amount of the Revolving Loan Commitment being refinanced, and any costs and expenses incurred to effect any such refinancing. Any repayment of the Term Loan A Loans or Term Loan B Loans, as applicable, from the proceeds of an Incremental Facility shall be applied pro rata across the remaining scheduled repayments set forth in Sections 2.7(b)(i) and 2.7(b)(ii) hereof, and any repayment of the Revolving Loans, if applicable, shall reduce the Revolving Loan Commitments in an amount equal to such repayment. No Incremental Facility Maturity Date for a Non-Refinancing Incremental Facility shall be earlier than six (6) months after the Term Loan B Maturity Date and no Incremental Facility Maturity Date for a Refinancing Incremental Facility shall be earlier than the Maturity Date for the Loans being refinanced with the proceeds of such Refinancing Incremental Facility. The decision of any Lender to provide an Incremental Facility Commitment to the Borrowers shall be at such Lender’s sole discretion and shall be made in writing. The Incremental Facility Commitment of a Lender providing an Incremental Facility Commitment shall be evidenced by an Incremental Facility Note. Persons not then Lenders may be included as Lenders holding a portion of such Incremental Facility Commitment with the written approval of the Borrowers and the Administrative Agent (such approval not to be unreasonably withheld, delayed, or conditioned). The Incremental Facility Commitments shall be governed by this Agreement and the other Loan Documents and be on terms and conditions no more restrictive than those set forth herein and therein. The terms and conditions in this Section 2.15 may be amended with the consent of the Majority Lenders and the Borrowers, except to the extent that a specific Lender’s consent is otherwise required with respect to an issuance by such Lender of any Incremental Facility Commitment.

-46-

(b) Prior to the effectiveness of any Incremental Facility Commitment, the Borrowers shall (i) deliver to the Administrative Agent and the Lenders a Notice of Incremental Facility Commitment; and (ii) provide revised projections to the Administrative Agent and the Lenders, which shall be in form and substance reasonably satisfactory to the Administrative Agent and which shall demonstrate the Borrowers’ ability to timely repay such Incremental Facility Commitment and any Incremental Facility Advances thereunder and to comply with the covenants contained in Sections 7.8, 7.9, 7.10 and 7.11 hereof.

(c) Incremental Facility Advances (i) shall bear interest at the Base Rate Basis or the LIBOR Basis; provided, however that the Applicable Margin with respect thereto shall be as agreed to by the Borrowers and the Lenders making such Incremental Facility Advances; (ii) subject to Section 2.15(a) hereof, shall be repaid as agreed to by the Borrowers and the Lenders making such Incremental Facility Advances but in no event shall the quarterly percentage repayment of the Incremental Facility Loans outstanding (in the case of term loans) exceed the quarterly percentage repayment of the Term Loan B Loans outstanding set forth in Section 2.7(b)(ii) hereof; and (iii) which are made under a Refinancing Incremental Facility shall have an interest rate no greater than the Interest Rate Bases for Term Loan B Loans. To the extent that the interest rate applicable to a Non-Refinancing Incremental Facility is greater than the Interest Rate Bases then applicable to the Term Loan B Loans by 0.25% or more, the Interest Rate Bases for the Term Loan B Loans shall be automatically increased to an amount which is 0.25% less than the interest rate for such Non-Refinancing Incremental Facility.

(d) Incremental Facility Advances (and Continuations and Conversions thereof) shall be requested by the Borrowers pursuant to a request (which shall be in substantially the form of a Request for Advance) delivered in the same manner as a Request for Advance, but (in the case of Incremental Facility Advances) shall be funded pro rata only by those Lenders holding an Incremental Facility Commitment.

No action, suit, proceeding or investigation is pending or, to the knowledge of the Borrowers, threatened (i) that calls into question the validity of this Agreement or any other Loan Document, or (ii) as to which there is a reasonable possibility of an adverse determination not fully covered by insurance which, if so determined adversely to any Borrower or any Restricted Subsidiary, would reasonably be expected to have a Materially Adverse Effect.

(j) Taxes. All federal and material state and other tax returns of the Borrowers and each Restricted Subsidiary required by law to be filed have been duly filed and all federal and material state and other taxes, including, without limitation, withholding taxes, assessments and other governmental charges or levies required to be paid by any Borrower or any Restricted Subsidiary or imposed upon any Borrower or any Restricted Subsidiary or any of their respective properties, income, profits or assets, which are due and payable, have been paid, except any such taxes (i) (x) the payment of which any Borrower or any Restricted Subsidiary is diligently contesting in good faith by appropriate proceedings, (y) for which adequate reserves in accordance with GAAP have been provided on the books of such Person, and (z) as to which no Lien other than a Permitted Lien has attached, or (ii) which may result from audits not yet conducted.

(k) Financial Statements. The Borrowers have furnished or caused to be furnished to the Administrative Agent and the Lenders as of the Agreement Date, the audited

-52-

financial statements for the Parent and its Subsidiaries on a consolidated basis for the fiscal year ended December 31, 2003, and unaudited financial statements for the Parent and its Subsidiaries for the fiscal quarter ended March 31, 2004, all of which have been prepared in accordance with GAAP and present fairly in all material respects the financial position of the Parent and its Subsidiaries on a consolidated basis, on and as at such dates and the results of operations for the periods then ended (subject, in the case of unaudited financial statements, to normal year-end and audit adjustments). None of the Borrowers nor any of the Restricted Subsidiaries has any material liabilities, contingent or otherwise, on the Agreement Date, other than as disclosed in the financial statements referred to in the preceding sentence, in the reports filed by the Parent with the Securities and Exchange Commission prior to the Agreement Date or as set forth or referred to in this Agreement or on Schedule 8 attached hereto.

(l) No Material Adverse Change. There has occurred no event since December 31, 2003 which has or which could reasonably be expected to have a Materially Adverse Effect.

(m) ERISA. Each Borrower and each Restricted Subsidiary and each of their respective Plans are in compliance with ERISA and the Code, except to the extent that the failure to so comply would not reasonably be expected to have a Materially Adverse Effect, and none of the Borrowers nor any of their ERISA Affiliates, including their Restricted Subsidiaries, has incurred any accumulated funding deficiency with respect to any such Plan within the meaning of ERISA or the Code. The Borrowers, each of their Restricted Subsidiaries, and each other ERISA Affiliate have complied in all material respects with all requirements of ERISA. No Borrower nor any of its Restricted Subsidiaries has made any promises of retirement or other benefits to employees (except as set forth in the Plans, in written agreements with such employees, or in such Person’s employee handbook and memoranda to employees) that would reasonably be expected to have a Materially Adverse Effect. No Borrower nor any of its ERISA Affiliates, including their Restricted Subsidiaries, has incurred any material liability to PBGC in connection with any such Plan. The assets of each such Plan which is subject to Title IV of ERISA are sufficient to provide the benefits under such Plan, the payment of which PBGC would guarantee if such Plan were terminated, and such assets are also sufficient to provide all other “benefit liabilities” (within the meaning of Section 4001 of ERISA) due under the Plan upon termination, except to the extent that any insufficiency of assets would not reasonably be expected to have a Materially Adverse Effect. No Reportable Event has occurred and is continuing with respect to any such Plan that would reasonably be expected to have a Materially Adverse Effect. No Plan or trust created thereunder, or party in interest (as defined in Section 3(14) of ERISA), or any fiduciary (as defined in Section 3(21) of ERISA), has engaged in a “prohibited transaction” (as such term is defined in Section 406 of ERISA or Section 4975 of the Code) which would subject such Plan or any other Plan of any Borrower or any Restricted Subsidiary, any trust created thereunder, or any such party in interest or fiduciary, or any party dealing with any such Plan or any such trust, to any tax or penalty on “prohibited transactions” imposed by Section 502 of ERISA or Section 4975 of the Code which would reasonably expected to have a Materially Adverse Effect. No Borrower nor any of its ERISA Affiliates, including their Restricted Subsidiaries, is or has been obligated to make any material payment to a Multiemployer Plan.

-53-

(n) Compliance with Regulations U and X. No Borrower nor any Restricted Subsidiary owns or presently intends to own any “margin stock” as defined in Regulations U and X (12 C.F.R. Parts 221 and 224) (the “Regulations”) of the Board of Governors of the Federal Reserve System (“margin stock”). Parent does not own or presently intend to own an amount of margin stock representing twenty-five percent (25%) or more of the total assets of Parent, as measured on both a consolidated and unconsolidated basis. If so requested by the Administrative Agent, the Borrowers will furnish the Administrative Agent with (i) a statement or statements in conformity with the requirements of Federal Reserve Form U-1 referred to in Regulation U of the Board of Governors of the Federal Reserve System and (ii) other documents evidencing its compliance with the margin regulations, as reasonably requested by the Administrative Agent. Neither the making of the Loans nor the use of proceeds thereof will violate, or be inconsistent with, the provisions of any of the Regulations.

(o) Investment Company Act. No Borrower nor any of the Restricted Subsidiaries is required to register under the provisions of the Investment Company Act of 1940, as amended.

(p) Governmental Regulation. No Borrower nor any Restricted Subsidiary is required to obtain any consent, approval, authorization, permit or license which has not already been obtained from, or effect any filing or registration which has not already been effected with, any federal, state or local regulatory authority in connection with the execution, delivery and performance, in accordance with their respective terms, of this Agreement or any other Loan Document, other than filing of appropriate Uniform Commercial Code financing statements.

(q) Absence of Default, Etc. The Borrowers and the Restricted Subsidiaries are in compliance in all material respects with all of the provisions of their respective partnership agreements, limited liability company agreements, Certificates or Articles of Incorporation and By-Laws, as the case may be, and no event has occurred or failed to occur which has not been remedied or waived, the occurrence or non-occurrence of which constitutes, (i) a Default or (ii) a material default by any Borrower or any Restricted Subsidiary under any indenture, agreement or other instrument relating to Indebtedness for Money Borrowed of such Person in the amount of $10,000,000.00 or more in the aggregate, any material License, or any judgment, decree or order to which any Borrower or any Restricted Subsidiary is a party or by which any Borrower or any Restricted Subsidiary or any of its respective properties may be bound or affected.

(r) Accuracy of Information. All information relating to the Borrowers or any Subsidiary of any Borrower and furnished in writing by or on behalf of the Borrowers or any Subsidiary of any Borrower to the Administrative Agent or the Lenders in connection with this Agreement and the transactions contemplated hereby, together with the filings of the Parent pursuant to the Exchange Act, taken as a whole, were, at the time furnished, correct, true and accurate in all material respects to the extent necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and all projections that were provided prior to the Agreement Date in connection with this Agreement to the Administrative Agent or the Lenders were prepared in good faith on the basis of assumptions

-54-

believed to be reasonable at the time, it being understood that actual results may differ from projections.

(s) Agreements with Affiliates. Except for the Tax Sharing Agreement and agreements or arrangements with Affiliates wherein the Borrowers or one or more of the Restricted Subsidiaries provides services to or receives services from such Affiliates for fair consideration or which are set forth on Schedule 7 attached hereto, no Borrower nor any Restricted Subsidiary has (i) any written agreements or binding arrangements of any kind with any Affiliate or (ii) any management or consulting agreements of any kind with any Affiliate, other than (x) those among the Borrowers, the Restricted Subsidiaries and/or the Parent, (y) employment arrangements with executive officers, including, without limitation, stock option grants of the Parent, and (z) Investments permitted by Section 7.6 hereof.

(t) Priority. The Security Interest is a valid and, upon filing of appropriate Uniform Commercial Code financing statements and/or mortgages, will, except for any Permitted Liens, be a perfected first priority security interest in the Collateral in favor of the Administrative Agent, for the benefit of itself, the Lenders and the Issuing Bank, securing, in accordance with the terms of the Security Documents, the Obligations, and the Collateral is subject to no Liens other than Permitted Liens. The Liens created by the Security Documents are enforceable as security for the Obligations in accordance with their terms with respect to the Collateral subject, as to enforcement of remedies, to the following qualifications: (i) an order of specific performance and an injunction are discretionary remedies and, in particular, may not be available where damages are considered an adequate remedy at law, and (ii) enforcement may be limited by bankruptcy, insolvency, liquidation, reorganization, reconstruction and other similar laws affecting enforcement of creditors’ rights generally (insofar as any such law relates to the bankruptcy, insolvency or similar event of any Borrower or any of the Restricted Subsidiaries, as the case may be).

(u) Indebtedness. Except as shown on the financial statements of the Parent described in Section 4.1(k) above, as permitted by Section 7.1(e) or as described on Schedule 8 attached hereto, none of the Parent, any Borrower, or any of the Restricted Subsidiaries has outstanding, as of the Agreement Date, any Indebtedness for Money Borrowed.

(v) Solvency. As of the Agreement Date and after giving effect to the transactions contemplated by the Loan Documents (i) the property of the Borrowers, at a fair valuation, will exceed the total amount of liabilities, including contingent liabilities of the Borrowers; (ii) the capital of the Borrowers will not be unreasonably small to conduct their business as such business is now conducted and expected to be conducted following the Agreement Date; (iii) the Borrowers will not have incurred debts, or have intended to incur debts, beyond their ability to pay such debts as they mature; and (iv) the present fair salable value of the assets of the Borrowers will be greater than the amount that will be required to pay their probable liabilities (including debts) as they become absolute and matured. For purposes of this Section, the amount of contingent liabilities at any time will be computed as the amount that, in light of all the facts and circumstances existing as such time, can reasonably be expected to become an actual or matured liability.

Section 9.3 Consultation with Counsel.

Section 9.5 Administrative Agent and Affiliates. With respect to the Revolving Loan Commitment and the Loans, the Administrative Agent shall have the same rights and powers hereunder as any other Lender, and the Administrative Agent and Affiliates of the Administrative Agent may accept deposits from, lend money to and generally engage in any kind of business with any Borrower, any of its Subsidiaries or other Affiliates of, or Persons doing business with, any Borrower, any of its Subsidiaries or other Affiliates, as if they were not affiliated with the Administrative Agent and without any obligation to account therefor.

Section 9.6 Responsibility of the Administrative Agent and Issuing Bank. The duties and obligations of the Administrative Agent and the Issuing Bank under this Agreement are only those expressly set forth in this Agreement. The Administrative Agent shall be entitled to assume that no Default or Event of Default has occurred and is continuing unless it has actual knowledge, or has been notified in writing by any Borrower, of such fact, or has been notified by a Lender in writing that such Lender considers that a Default or an Event of Default has occurred and is continuing, and such Lender shall specify in detail the nature thereof in writing. The Administrative Agent and the Issuing Bank shall not be liable hereunder for any action taken or omitted to be taken except for its own respective gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court of competent jurisdiction.

Section 9.7 Action by the Administrative Agent and Issuing Bank.

(a) The Administrative Agent and the Issuing Bank shall be entitled to use its discretion with respect to exercising or refraining from exercising any rights which may be vested in it by, and with respect to taking or refraining from taking any action or actions which it may be able to take under or in respect of, this Agreement, unless the Administrative Agent and the Issuing Bank or the Issuing Bank, as applicable, shall have been instructed by the Majority Lenders (or, where expressly required, all Lenders) to exercise or refrain from exercising such rights or to take or refrain from taking such action; provided, however, that the Administrative Agent shall not exercise any rights under Section 8.2(a) hereof without the request of the Majority Lenders (or, where expressly required, all the Lenders), unless time is of the essence, in which case, such action can be taken at the discretion of the Administrative Agent. The Administrative Agent shall incur no liability under or in respect of this Agreement with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment or which may seem to it to be necessary or desirable in the circumstances, except for its gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court having jurisdiction over the subject matter.

In the event that the Administrative Agent, any Lender or the Issuing Bank shall acquire actual knowledge, or shall have been notified, of any Default or Event of Default, the Administrative Agent, such Lender or the Issuing Bank shall promptly notify the Lenders (provided, however, that the failure to give such notice shall not result in any liability on the part of such Lender, the Issuing Bank or the Administrative Agent), and the Administrative Agent shall take such action and assert such rights under this Agreement and the other Loan Documents as the Majority Lenders shall request in writing, and the Administrative Agent shall not be subject to any liability by reason of its acting pursuant to any such request. If the Majority Lenders shall fail to request the Administrative Agent to take action or to assert rights under this Agreement or any other Loan Documents in respect of any Default or Event of Default within ten (10) days after their receipt of the notice of any Default or Event of Default from the Administrative Agent, any Lender or the Issuing Bank, or shall request inconsistent action with respect to such Default or Event of Default, the Administrative Agent may, but shall not be required to, take such action and assert such rights (other than rights under Article 8 hereof) as it deems in its discretion to be advisable for the protection of the Lenders, except that, if the Majority Lenders have instructed the Administrative Agent not to take such action or assert such right, in no event shall the Administrative Agent act contrary to such instructions, unless time is of the essence, in which case, the Administrative Agent may act in accordance with its reasonable discretion.

Section 9.9 Responsibility Disclaimed. The Administrative Agent shall not be under any liability or responsibility whatsoever as Administrative Agent:

Section 9.11 Credit Decision. Each Lender confirms that:

(a) in making its decision to enter into this Agreement and to make its portion of the Loans it has independently taken whatever steps it considers necessary to evaluate the financial condition and affairs of the Borrowers and that it has made an independent credit judgment, and that it has not relied upon the Administrative Agent or information provided by the Administrative Agent (other than information provided to the Administrative Agent by the Borrowers and forwarded by the Administrative Agent to the Lenders); and

(b) so long as any portion of the Loans remains outstanding or such Lender has an obligation to make its portion of Advances hereunder, it will continue to make its own independent evaluation of the financial condition and affairs of the Borrowers.

Section 9.12 Successor Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by giving written notice thereof to the Lenders, the Issuing Bank and the Borrowers and may be removed at any time for cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent which appointment shall, prior to a Default, be subject to the consent of the Borrowers, acting reasonably. If (a) no successor Administrative Agent shall have been so appointed by the Majority Lenders or (b) if appointed, no successor Administrative Agent shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gave notice of resignation or the Majority Lenders removed the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be any Lender or a commercial bank organized under the laws of the United States of America or any political subdivision thereof

-81-

which has combined capital and reserves in excess of $250,000,000.00 and which shall be reasonably acceptable to the Borrowers. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges, duties and obligations of the retiring Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent the provisions of this Article shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent. In the event that the Administrative Agent or any of its respective Affiliates ceases to be a Lender hereunder, such Person shall resign its agency hereunder.

Section 9.13 Delegation of Duties. The Administrative Agent may execute any of its duties under the Loan Documents by or through agents or attorneys selected by it using reasonable care, and shall be entitled to advice of counsel concerning all matters pertaining to such duties.

Section 9.14 No Responsibilities of the Agents. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Syndication Agent and the Co-Documentation Agents shall not have any duties or responsibilities, nor shall the Syndication Agent or the Co-Documentation Agents have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Syndication Agent and the Co-Documentation Agents.

ARTICLE 10 - CHANGES IN CIRCUMSTANCES

AFFECTING LIBOR ADVANCES AND INCREASED COSTS

Section 10.1 LIBOR Basis Determination Inadequate or Unfair. If with respect to any proposed LIBOR Advance for any Interest Period, the Administrative Agent determines after consultation with the Lenders that adequate and fair means do not exist for determining the LIBOR Basis, the Administrative Agent shall forthwith give notice thereof to the Borrowers and the Lenders, whereupon until the Administrative Agent notifies the Borrowers that the circumstances giving rise to such situation no longer exist, the obligations of any affected Lender to make its portion of such LIBOR Advances shall be suspended and each affected Lender shall make its portion of such LIBOR Advance as a Base Rate Advance.

Section 10.2 Illegality. If after the date hereof, the adoption of any Applicable Law, or any change in any Applicable Law (whether adopted before or after the Agreement Date), or any change in interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender with any directive (whether or not having the force of law) of any such authority, central bank or comparable agency, shall make it unlawful or impossible for any Lender to make, maintain or fund its portion of LIBOR Advances, such Lender shall so notify the Administrative Agent, and the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrowers. Before giving any notice to the Administrative Agent pursuant to this Section 10.2, such Lender shall designate a different lending office if such designation will avoid the

-82-

need for giving such notice and will not, in the sole reasonable judgment of such Lender, be otherwise materially disadvantageous to such Lender. Upon receipt of such notice, notwithstanding anything contained in Article 2 hereof, the Borrowers shall repay in full the then outstanding principal amount of such Lender’s portion of each affected LIBOR Advance, together with accrued interest thereon, on either (a) the last day of the then current Interest Period applicable to such affected LIBOR Advances if such Lender may lawfully continue to maintain and fund its portion of such LIBOR Advance to such day or (b) immediately if such Lender may not lawfully continue to fund and maintain its portion of such affected LIBOR Advances to such day. Concurrently with repaying such portion of each affected LIBOR Advance, the Borrowers may borrow a Base Rate Advance from such Lender, whether or not it would have been entitled to effect such borrowing, and such Lender shall make such Advance, if so requested, in an amount such that the outstanding principal amount of the affected Note held by such Lender shall equal the outstanding principal amount of such Note immediately prior to such repayment.

Section 10.3 Increased Costs and Additional Amounts.

(a) If after the date hereof, the adoption of any Applicable Law, or any change in any Applicable Law (whether adopted before or after the Agreement Date), or any interpretation or change in interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof or compliance by any Lender with any directive issued after the Agreement Date (whether or not having the force of law) of any such authority, central bank or comparable agency:

(i) shall subject any Lender to any tax, duty or other charge with respect to its obligation to make its portion of LIBOR Advances, or its portion of other Advances, or shall change the basis of taxation of payments to any Lender of the principal of or interest on its portion of LIBOR Advances or in respect of any other amounts due under this Agreement, or its obligation to make its portion of Advances (except for changes in the rate or method of calculation of tax on the revenues or net income of such Lender, and except for any Taxes referred to in Section 10.3(b) hereof); or

(ii) shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System, but excluding any included in an applicable Eurodollar Reserve Percentage), special deposit, capital adequacy, assessment or other requirement or condition against assets of, deposits with or for the account of, or commitments or credit extended by, any Lender or shall impose on any Lender or the London interbank borrowing market any other condition affecting its obligation to make its portion of such LIBOR Advances or its portion of existing Advances;

and the result of any of the foregoing is to increase the cost to such Lender of making or maintaining any of its portion of LIBOR Advances, or to reduce the amount of any sum received or receivable by such Lender under this Agreement or under its Note with respect thereto, then,

-83-

within ten (10) days after demand by such Lender, the Borrowers agree to pay to such Lender such additional amount or amounts as will compensate such Lender on an after-tax basis for such increased costs.

(b) All payments made by the Borrowers under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income or other similar taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”), now or hereafter imposed, levied, collected, withheld or assessed by any governmental authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed on any Lender as a result of present or former connection between such Person and the jurisdiction of the governmental authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from such Person having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded Taxes (collectively, the “Non-Excluded Taxes”) are required to be withheld from any amounts payable to any Lender hereunder, the amounts so payable to such Person shall be increased to the extent necessary to yield to such Person (after payment of all Non-Excluded Taxes) interest on any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement; provided, however, that the Borrowers shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Person fails to comply with the requirements of Section 2.13 hereof. Whenever any Non-Excluded Taxes are payable by the Borrowers, as promptly as possible thereafter the Borrowers shall send to the Administrative Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrowers showing payment thereof. If the Borrowers fail to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other documentary evidence, the Borrowers shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as result of any such failure. The Borrowers shall make any payments required pursuant to the immediately preceding sentence within thirty (30) days after receipt of written demand therefor from the Administrative Agent or any Lender, as the case may be. The agreements set forth in this Section 10.3 shall survive the termination of this Agreement and the payment of the Obligations. Each Lender will promptly notify the Borrowers and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 10.3 and will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole reasonable judgment of such Lender made in good faith, be otherwise disadvantageous to such Lender. Notwithstanding any provision herein to the contrary, the Borrowers shall have no obligation to pay to any Lender any amount which the Borrowers are liable to withhold due to the failure of such Lender to file any statement of exemption required under the Code in order to permit the Borrowers to make payments to such Lender without such withholding.

(c) Any Lender claiming compensation under this Section 10.3 shall provide the Borrowers with a written certificate setting forth the additional amount or amounts to be paid to it hereunder and calculations therefor in reasonable detail. Such certificate shall be presumptively correct absent manifest error. In determining such amount, such Lender may use

-84-

any reasonable averaging and attribution methods. If any Lender demands compensation under this Section 10.3, the Borrowers may at any time, upon at least five (5) Business Days’ prior notice to such Lender, prepay in full such Lender’s portion of the then outstanding LIBOR Advances, together with accrued interest and fees thereon to the date of prepayment, along with any reimbursement required under Section 2.10 hereof and this Section 10.3. Concurrently with prepaying such portion of LIBOR Advances the Borrowers may, whether or not then entitled to make such borrowing, borrow a Base Rate Advance, or a LIBOR Advance not so affected, from such Lender, and such Lender shall, if so requested, make such Advance in an amount such that the outstanding principal amount of the affected Note or Notes held by such Lender shall equal the outstanding principal amount of such Note or Notes immediately prior to such prepayment.

Section 10.4 Effect On Other Advances. If notice has been given pursuant to Section 10.1, 10.2 or 10.3 hereof suspending the obligation of any Lender to make its portion of any type of LIBOR Advance, or requiring such Lender’s portion of LIBOR Advances to be repaid or prepaid, then, unless and until such Lender notifies the Borrowers that the circumstances giving rise to such repayment no longer apply, all amounts which would otherwise be made by such Lender as its portion of LIBOR Advances shall be instead as Base Rate Advances, unless otherwise notified by any of the Borrowers.

Section 11.2 Expenses. The Borrowers will promptly pay, or reimburse, in each case jointly and severally:

(a) all reasonable out-of-pocket expenses of the Administrative Agent in connection with the preparation, negotiation, execution and delivery of this Agreement and the other Loan Documents, and the transactions contemplated hereunder and thereunder any amendments, waivers and consents associated therewith, including, without limitation, the reasonable fees and disbursements of Kilpatrick Stockton LLP, Atlanta, Georgia, special counsel for the Administrative Agent; and

(b) all reasonable out-of-pocket costs and expenses of the Administrative Agent, the Lenders and the Issuing Bank of enforcement under this Agreement or the other Loan Documents and all reasonable out-of-pocket costs and expenses of collection if an Event of Default occurs in the payment of the Notes, which in each case shall include, without limitation, reasonable fees and out-of-pocket expenses of counsel for the Administrative Agent, each of the Lenders and the Issuing Bank.

Section 11.3 Waivers. The rights and remedies of the Administrative Agent, the Lenders and the Issuing Bank under this Agreement and the other Loan Documents shall be cumulative and not exclusive of any rights or remedies which they would otherwise have. No failure or delay by the Administrative Agent, the Majority Lenders, the Super Majority Lenders, the Lenders and the Issuing Bank, or any of them, in exercising any right, shall operate as a waiver of such right. No waiver of any provision of this Agreement or consent to any departure by any Borrower or Restricted Subsidiary therefrom shall in any event be effective unless the same shall be permitted by Section 11.12, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time.

Section 11.4 Set-Off. In addition to any rights now or hereafter granted under Applicable Law and not by way of limitation of any such rights, upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent, each of the Lenders, Affiliates of any Lender and the Issuing Bank are hereby authorized by the Borrowers to the extent permitted by Applicable Law, at any time or from time to time, without notice to the Borrowers or to any other Person, any such notice being, to the extent permitted by Applicable Law, hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, time or demand, including, without limitation, Indebtedness evidenced by certificates of deposit, in each case whether matured or unmatured) and any other Indebtedness at any time owing by any such Lender, Affiliate of any Lender, the Administrative Agent or the Issuing Bank, to or for the credit or the account of the Borrowers, against and on account of the obligations and liabilities of the Borrowers to the Lenders, the Administrative Agent and the Issuing Bank now or hereafter existing under this Agreement, including, without limitation, all Obligations, the Notes or any other Loan Document, irrespective of whether (a) any Lender, the

-87-

Administrative Agent or the Issuing Bank, as applicable shall have made any demand hereunder or (b) any Lender, Administrative Agent or the Issuing Bank shall have declared the principal of and interest on the Loans and other amounts due hereunder to be due and payable as permitted by Section 8.2 hereof and although such obligations and liabilities or any of them shall be contingent or unmatured. Upon direction by the Administrative Agent, with the consent of all of the Lenders, each Lender or the Issuing Bank holding deposits of any Borrower or any Restricted Subsidiary shall, to the extent not prohibited by Applicable Law, exercise its set-off rights as so directed; and, within one (1) Business Day following any such set-off, the Administrative Agent shall give notice thereof to the Borrowers. Notwithstanding anything to the contrary contained in this Section 11.4, no Lender nor the Issuing Bank shall exercise any right of set-off without the prior consent of the Majority Lenders so long as the Obligations shall be secured by any real property or real property interest, it being understood and agreed that the provisions of this sentence are for the exclusive benefit of the Lenders and the Issuing Bank, may be amended, modified or waived by the Majority Lenders without notice to or consent of the Borrowers or any Subsidiary and shall not constitute a waiver of any rights against the Borrowers or any Subsidiary or against any Collateral.

Section 11.5 Assignment and Participation.

(a) No Borrower may assign or transfer any of its rights or obligations hereunder, under the Notes or under any other Loan Document without the prior written consent of each Lender and the Issuing Bank.

(b) Each Lender may at any time sell assignments or participations of up to one hundred percent (100%) of its interest hereunder to (A) one (1) or more wholly-owned Affiliates of such Lender or Approved Funds (provided, however, that if such Affiliate is not a financial institution, such Lender shall be obligated to repurchase such assignment if such Affiliate is unable to honor its obligations hereunder), (B) any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank (provided, however, that no such assignment shall relieve such Lender from its obligations hereunder) or (C) any Lender.

(c) Each Lender may at any time sell assignments or participations to one or more Persons pursuant to which each Lender may assign or participate its interest under this Agreement and the other Loan Documents, including its interest in any particular Advance or portion thereof; provided, however, that (1) all assignments (other than assignments described in Section 11.5(b) hereof) shall be in minimum principal amounts of the lesser of (X) $1,000,000.00 or (Y) the amount of such Lender’s Revolving Loan Commitment, Term Loan A Loans, Term Loan B Loans or Incremental Facility Commitment (in a single assignment only), and (2) all assignments and participations (other than assignments and participations described in Section 11.5(b) hereof) hereunder shall be subject to the following additional terms and conditions:

(i) no assignment shall be sold without the prior consent of the Administrative Agent and, prior to the occurrence and continuation of a Default or Event of Default, the consent of the Borrowers, in each case, which consent shall not be unreasonably withheld, delayed or conditioned;

-88-

(ii) any Person purchasing a participation or an assignment of any portion of the Loans from any Lender shall be required to represent and warrant that its purchase shall not constitute a “prohibited transaction” (as defined in Section 4.1(m) hereof);

(iii) the Borrowers, the Lenders, and the Administrative Agent agree that assignments permitted hereunder (including the assignment of any Advance or portion thereof) may be made with all voting rights, and shall be made pursuant to an Assignment and Assumption Agreement substantially in the form of Exhibit S attached hereto, and an administrative fee of $3,500.00 shall be payable to the Administrative Agent either by the assigning Lender or the assignee thereof at the time of any assignment under this Section 11.5(c);

(iv) no participation agreement shall confer any rights under this Agreement or any other Loan Document to any purchaser thereof, or relieve any issuing Lender from any of its obligations under this Agreement, and all actions hereunder shall be conducted as if no such participation had been granted; provided, however, that any participation agreement may confer on the participant the right to approve or disapprove items requiring unanimous Lender consent pursuant to Section 11.12 hereof;

(v) each Lender agrees to provide the Administrative Agent and the Borrowers with prompt written notice of any issuance of assignments of its interests hereunder;

(vi) no assignment, participation or other transfer of any rights hereunder or under the Notes shall be effected that would result in any interest requiring registration under the Securities Act of 1933, as amended, or qualification under any state securities law;

(vii) no such assignment may be made to any bank or other financial institution (x) with respect to which a receiver or conservator (including, without limitation, the Federal Deposit Insurance Corporation, the Resolution Trust Company or the Office of Thrift Supervision) has been appointed or (y) that is not “adequately capitalized” (as such term is defined in Section 131(b)(1)(B) of the Federal Deposit Insurance Corporation Improvement Act as in effect on the Agreement Date); and

(viii) if applicable, each Lender shall, and shall cause each of its assignees to, provide to the Administrative Agent on or prior to the effective date of any assignment an appropriate Internal Revenue Service form as required by Applicable Law supporting such Lender’s or assignee’s position that no withholding by any Borrower or the Administrative Agent for United States income tax payable by such Lender or assignee in respect of amounts received by it hereunder is required. For purposes of this Agreement, an appropriate Internal Revenue Service form shall mean Internal Revenue Service Form W-8BEN or W-8ECI,

-89-

or any successor or related forms adopted by the relevant United States taxing authorities.

(d) Except as specifically set forth in Section 11.5(b) or (c) hereof, nothing in this Agreement or the Notes, expressed or implied, is intended to or shall confer on any Person other than the respective parties hereto and thereto and their successors and assignees permitted hereunder and thereunder any benefit or any legal or equitable right, remedy or other claim under this Agreement or the Notes.

(e) In the case of any participation, all amounts payable by the Borrowers under the Loan Documents shall be calculated and made in the manner and to the parties hereto as if no such participation had been sold.

(f) The provisions of this Section 11.5 shall not apply to any purchase of participations among the Lenders pursuant to Section 2.11 hereof.

(g) The Administrative Agent, acting, for this purpose only, as agent of the Borrowers shall maintain, at no extra charge to the Borrowers, a register (the “Register”) at the address to which notices to the Administrative Agent are to be sent under Section 11.1 hereof on which Register the Administrative Agent shall enter the name, address and taxpayer identification number (if provided) of the registered owner of the Loans evidenced by a Registered Note or, upon the request of the registered owner, for which a Registered Note has been requested. A Registered Note and the Loans evidenced thereby may be assigned or otherwise transferred in whole or in part only by registration of such assignment or transfer of such Registered Note and the Loans evidenced thereby on the Register. Any assignment or transfer of all or part of such Loans and the Registered Note evidencing the same shall be registered on the Register only upon compliance with the other provisions of this Section 11.5 and surrender for registration of assignment or transfer of the Registered Note evidencing such Loans, duly endorsed by (or accompanied by a written instrument of assignment or transfer duly executed by) the Registered Noteholder thereof, and thereupon one or more new Registered Notes in the same aggregate principal amount shall be issued to the designated assignee(s) or transferee(s) and, if less than the aggregate principal amount of such Registered Notes is thereby transferred, the assignor or transferor. Prior to the due presentment for registration of transfer of any Registered Note, the Borrowers and the Administrative Agent shall treat the Person in whose name such Loans and the Registered Note evidencing the same is registered as the owner thereof for the purpose of receiving all payments thereon and for all other purposes, notwithstanding any notice to the contrary.

(h) The Register shall be available for inspection by the Borrowers and any Lender at any reasonable time during the Administrative Agent’s regular business hours upon reasonable prior notice.

(i) Notwithstanding any other provision in this Agreement, any Lender that is a fund that invests in bank loans may, without the consent of the Administrative Agent or the Borrowers, pledge all or any portion of its rights under, and interest in, this Agreement and the Notes to any trustee or to any other representative of holders of obligations owed or securities issued, by such fund as security for such obligations or securities; provided,

-90-

however, that any transfer to any Person upon the enforcement of such pledge or security interest may only be made subject to the assignment provisions of this Section 11.5.

(j) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) sponsored by such Granting Lender, identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrowers, the option to provide to the Borrowers all or any part of any Advance that such Granting Lender would otherwise be obligated to make to the Borrowers pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The Loans by an SPC hereunder shall be Revolving Loans, Term Loan A Loans, Term Loan B Loans and/or, if applicable, Incremental Facility Loans of the Granting Lender to the same extent, and as if, such Loans were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it, solely in its capacity as a party hereto and to any other Loan Document, will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 11.5, any SPC may (i) with notice to, but without the prior written consent of, the Borrowers and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Advances to the Granting Lender or to any financial institutions (consented to by the Borrowers and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Advances and (ii) disclose on a confidential basis any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 11.5(j) may not be amended without the written consent of any SPC which has been designated in writing as provided in the first sentence hereof and holds any outstanding Loans. The designation by a Granting Lender of an SPC to fund Advances (i) shall be deemed to be a representation, warranty, covenant and agreement by such Granting Lender to the Borrowers and all other parties hereunder that (A) the funding and maintaining of such Advances by such SPC shall not constitute a “prohibited transaction” (as defined in Section 4.1(m) hereof), and (B) such designation, funding and maintenance would not result in any interest requiring registration under the Securities Act of 1933, as amended, or qualification under any state securities law, and shall from time to time provide to the Borrowers the tax and other forms required pursuant to Section 2.09(e) hereof with respect to such SPC as though such SPC were a Lender hereunder. In no event shall the Borrowers or any Lender other than the Granting Lender be obligated hereunder to pay any additional amounts under any provision of this Agreement (pursuant to Article 10 hereof or otherwise) by reason of a Granting Lender’s designation of an SPC or the funding or maintenance of Advances by such SPC, in excess of amounts which the Borrowers would have been obligated to pay if such Granting Lender had not made such designation and such Granting Lender were itself funding and maintaining such Advances. The Administrative

-91-

Agent shall register the interest of any SPC in an Advance from time to time on the Register maintained pursuant to Section 11.5(g) hereof.

Section 11.6 Accounting Principles. All references in this Agreement to GAAP shall be to such principles as in effect from time to time. All accounting terms used herein without definition shall be used as defined under GAAP. All references to the financial statements of the Borrowers and to their Annualized Operating Cash Flow, Senior Debt, Operating Cash Flow, Total Debt, Fixed Charges, Interest Expense, and other such terms shall be deemed to refer to such items of the Borrowers and the Restricted Subsidiaries, on a fully consolidated basis. The Borrowers shall deliver to the Lenders at the same time as the delivery of any quarterly or annual financial statements required pursuant to Section 6.1 or 6.2 hereof, as applicable, (a) a description in reasonable detail of any material variation between the application of GAAP employed in the preparation of such statements and the application of GAAP employed in the preparation of the next preceding quarterly or annual financial statements, as applicable, and (b) reasonable estimates of the differences between such statements arising as a consequence thereof. If, within thirty (30) days after the delivery of the quarterly or annual financial statements referred to in the immediately preceding sentence, the Majority Lenders shall object in writing to the Borrowers’ determining compliance hereunder on such basis, (1) calculations for the purposes of determining compliance hereunder shall be made on a basis consistent with those used in the preparation of the latest financial statements as to which such objection shall not have been made, or (2) if requested by the Borrowers, the Majority Lenders will negotiate in good faith to amend the covenants herein to give effect to the changes in GAAP in a manner consistent with this Agreement (and so long as the Borrowers comply in good faith with the provisions of this Section 11.6, no Default or Event of Default shall occur hereunder solely as a result of such changes in GAAP).

Section 11.7 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument.

Section 11.8 Governing Law. This Agreement and the Notes shall be construed in accordance with and governed by the internal laws of the State of New York applicable to agreements made and to be performed the State of New York. If any action or proceeding shall be brought by the Administrative Agent or any Lender hereunder or under any other Loan Document in order to enforce any right or remedy under this Agreement or under any Note or any other Loan Document, each of the Borrowers hereby consents and will, and each of the Borrowers will cause each Restricted Subsidiary to, submit to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement. Each of the Borrowers, for itself and on behalf of its Restricted Subsidiaries, hereby agrees that, to the extent permitted by Applicable Law, service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrowers at the address given in Section 11.1 hereof and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

-92-

Section 11.9 Severability. To the extent permitted by law, any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

Section 11.10 Interest.

(a) In no event shall the amount of interest due or payable hereunder or under the Notes exceed the maximum rate of interest allowed by Applicable Law, and in the event any such payment is inadvertently made by the Borrowers or inadvertently received by the Administrative Agent or any Lender, then such excess sum shall be credited as a payment of principal, unless, if no Event of Default shall have occurred and be continuing, the Borrowers shall notify the Administrative Agent or such Lender, in writing, that it elects to have such excess sum returned forthwith. It is the express intent hereof that the Borrowers not pay and the Administrative Agent and the Lenders not receive, directly or indirectly in any manner whatsoever, interest in excess of that which may legally be paid by the Borrowers under Applicable Law.

(b) Notwithstanding the use by the Lenders of the Base Rate and the LIBOR as reference rates for the determination of interest on the Loans, the Lenders shall be under no obligation to obtain funds from any particular source in order to charge interest to the Borrowers at interest rates related to such reference rates.

Section 11.11 Table of Contents and Headings. The Table of Contents and the headings of the various subdivisions used in this Agreement are for convenience only and shall not in any way modify or amend any of the terms or provisions hereof, nor be used in connection with the interpretation of any provision hereof.

Section 11.12 Amendment and Waiver. Neither this Agreement nor any Loan Document nor any term hereof or thereof may be amended orally, nor may any provision hereof or thereof be waived orally but only by an instrument in writing signed by or at the written direction of:

(a) except as set forth in (b), (c) and (d) below, the Majority Lenders and, in the case of any amendment, by the Borrowers;

Section 11.13 Entire Agreement. Except as otherwise expressly provided herein, this Agreement, the other Loan Documents and the other documents described or contemplated herein or therein will embody the entire agreement and understanding among the parties hereto and thereto and supersede all prior agreements and understandings relating to the subject matter hereof and thereof.

Section 11.14 Other Relationships. No relationship created hereunder or under any other Loan Document shall in any way affect the ability of the Administrative Agent, the Issuing Bank and each Lender to enter into or maintain business relationships with any Borrower or any Affiliate thereof beyond the relationships specifically contemplated by this Agreement and the other Loan Documents.

Section 11.15 Directly or Indirectly. If any provision in this Agreement refers to any action taken or to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person, whether or not expressly specified in such provision.

-94-

Agent, each of the Lenders and the Issuing Bank notwithstanding any investigation heretofore or hereafter made by them and (b) survive the execution and delivery of the Notes and shall continue in full force and effect so long as any Note is outstanding and unpaid.

The Obligations are secured by the Security Documents and are intended by the parties hereto to be in parity with the Interest Hedge Agreements that are Loan Documents and senior in right of payment to the 2003 Senior Subordinated Discount Notes, the November 2003 Senior Subordinated Notes and any other Indebtedness for Money Borrowed of the Borrowers issued after the Agreement Date which by its terms is subordinated to the Obligations.

Section 11.18 Obligations. The obligations of the Administrative Agent, each of the Lenders and the Issuing Bank hereunder are several, not joint.

The Administrative Agent, the Lenders and the Issuing Bank shall hold confidentially all non-public and proprietary information and all other information designated by the Borrowers as confidential, in each case, obtained from the Borrowers or their Affiliates pursuant to the requirements of this Agreement in accordance with their customary procedures for handling confidential information of this nature and in accordance with safe and sound lending practices; provided, however, that the Administrative Agent, the Lenders and the Issuing Bank may make disclosure of any such information (a) to their examiners, Affiliates, any Approved Fund, outside auditors, counsel, consultants, appraisers, other professional advisors and any direct or indirect contractual counterparty in swap agreements or such counterparty’s professional advisor in connection with this Agreement or as reasonably required by any proposed syndicate member or any proposed transferee or participant in connection with the contemplated transfer of any Note or participation therein (including, without limitation, any pledgee referred to in Section 11.5(i) hereof), in each case, so long as any such Person (other than any examiners) receiving such information is advised of the provisions of this Section 11.19 and agrees to be bound thereby, (b) as required or requested by any governmental authority or self-regulatory body or representative thereof or in connection with the enforcement hereof or of any Loan Document or related document or (c) pursuant to legal process or with respect to any litigation between or among any Borrower and any of the Administrative Agent, the Lenders or the Issuing Bank. In no event shall the Administrative Agent, any Lender or the Issuing Bank be obligated or required to return any materials furnished to it by the Borrowers.

-95-

Section 11.20 Guarantors. To the extent any Borrower has not directly received the proceeds of all Advances hereunder, such Borrower may be deemed to be a guarantor with respect to such Advances rather than a joint and several co-obligor and, accordingly, each party hereto agrees that the liability of such Borrower as a guarantor hereunder would be solely in accordance with, and subject to the limitations contained in, the Borrower Guaranty executed by such Borrower in favor of the Administrative Agent and the Lenders.

TO LOAN AGREEMENT

FORM OF BORROWER’S GUARANTY

([Borrower])

THIS GUARANTY (the “Guaranty”) is made as of the day of , 2004, by [Borrower], a Delaware [ ] (the “Guarantor”), in favor of the Guarantied Parties defined below. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned thereto in the Loan Agreement.

W I T N E S S E T H:

WHEREAS, the Guarantor, [American Tower, L.P., a Delaware limited partnership (“AT LP”)], [American Towers, Inc., a Delaware corporation (“AT Inc.”)], [American Tower International, Inc., a Delaware corporation (“AT International”)], [American Tower LLC, a Delaware limited liability company (“AT LLC”)] (collectively with [AT Inc.], [AT LP], [AT LLC] and [AT International], the “Borrowers”), the Lenders (as defined therein), the Issuing Bank (as defined therein) and Toronto Dominion (Texas), Inc., as administrative agent thereunder (the “Administrative Agent”, and together with the Lenders and the Issuing Bank, the “Guarantied Parties”) are all parties to that certain Loan Agreement dated as of May 24, 2004 (as amended, modified, restated or supplemented from time to time, and as in effect on the date hereof, the “Loan Agreement”); and

WHEREAS, pursuant to the terms of the Loan Agreement, the Guarantor is required to execute and deliver this Guaranty; and

WHEREAS, the Guarantor and the Borrowers are mutually dependent on each other in the conduct of their respective businesses as an integrated operation, and each of the Borrowers has as one of its corporate purposes the obtaining of financing needed from time to time by the Guarantor, with the ability of each of the Borrowers to obtain such financing being dependent, in part, on the successful operations of and the properties owned by the Guarantor; and

WHEREAS, the Guarantor has determined that its execution, delivery and performance of this Guaranty benefit, and are within the corporate purposes and in the best interests of, the Guarantor; and

WHEREAS, as a condition to the extension of the Loans by the Guarantied Parties and the issuance of Letters of Credit by the Issuing Bank, the Guarantor has agreed to execute this Guaranty, guaranteeing the payment by the Borrowers of the Obligations under the Loan Agreement, the Notes and the other Loan Documents, subject to Section 8 hereof (collectively, the “Guarantied Obligations”); and

NOW, THEREFORE, in consideration of the above premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, subject to the provisions of Section 8 hereof.

The Guarantor hereby agrees, for the benefit of the Guarantied Parties, as follows:

1. The Guarantor hereby unconditionally guarantees to the Guarantied Parties full and prompt payment when due whether at maturity, by acceleration or otherwise of all Guarantied Obligations.

2. Obligations Several. Regardless of whether any proposed guarantor or any other Person or Persons is, are or shall become in any other way responsible to the Guarantied Parties, or any of them, for or in respect of the Guarantied Obligations or any part thereof, and regardless of whether or not any Person or Persons now or hereafter responsible to the Guarantied Parties, or any of them, for the Guarantied Obligations or any part thereof, whether under this Guaranty or otherwise, shall cease to be so liable, the Guarantor hereby declares and agrees that this Guaranty is and shall continue to be a several obligation, shall be a continuing guaranty and shall be operative and binding.

3. Guaranty Final. Upon the execution and delivery of this Guaranty to the Administrative Agent, this Guaranty shall be deemed to be finally executed and delivered by the Guarantor and shall not be subject to or affected by any promise or condition affecting or limiting the Guarantor’s liability (other than as expressly set forth in Section 8 hereof), and no statement, representation, agreement or promise on the part of the Guarantied Parties, the Borrowers, or any of them, or any officer, employee or agent thereof, unless contained herein forms any part of this Guaranty or has induced the making hereof or shall be deemed in any way to affect the Guarantor’s liability hereunder.

4. Amendment and Waiver. No alteration or waiver of this Guaranty or of any of its terms, provisions or conditions shall be binding upon the Persons against whom enforcement is sought unless made in writing and signed by an authorized officer of such Person.

5. Dealings with Guarantor. The Guarantied Parties, or any of them, may, from time to time, without exonerating or releasing the Guarantor in any way under this Guaranty, (i) take such further or other security or securities for the Guarantied Obligations or any part thereof as the Guarantied Parties, or any of them, may deem proper, consistent with the Loan Agreement, or (ii) release, discharge, abandon or otherwise deal with or fail to deal with any guarantor or other obligor of the Guarantied Obligations or any security or securities therefor or any part thereof now or hereafter held by the Guarantied Parties, or any of them, or (iii) consistent with the Loan Agreement, amend, modify, extend, accelerate or waive in any manner any of the provisions, terms, or conditions of any of the Loan Documents, all as the Guarantied Parties, or any of them, may consider expedient or appropriate in their sole discretion. Without limiting the generality of the foregoing, or of Paragraph 6 hereof, it is understood that the Guarantied Parties, or any of them, may, without exonerating or releasing the

-2-

Guarantor, give up, or modify or abstain from perfecting or taking advantage of any security for the Guarantied Obligations and accept or make any compositions or arrangements, and realize upon any security for the Guarantied Obligations when, and in such manner, as the Guarantied Parties, or any of them, may deem expedient, consistent with the Loan Agreement, all without notice to the Guarantor, except as required by Applicable Law.

6. Guaranty Unconditional. The Guarantor acknowledges and agrees that no change in the nature or terms of the Guarantied Obligations or any of the Loan Documents, or other agreements, instruments or contracts evidencing, related to or attendant with the Guarantied Obligations (including any novation), nor any determination of lack of enforceability thereof, shall discharge all or any part of the liabilities and obligations of the Guarantor pursuant to this Guaranty; it being the purpose and intent of the Guarantor and the Guarantied Parties that the covenants, agreements and all liabilities and obligations of the Guarantor hereunder are absolute, unconditional and irrevocable under any and all circumstances. Without limiting the generality of the foregoing, the Guarantor agrees that until each and every one of the covenants and agreements of this Guaranty is fully performed, the Guarantor’s undertakings hereunder shall not be released, in whole or in part, by any action or thing which might, but for this paragraph of this Guaranty, be deemed a legal or equitable discharge of a surety or guarantor, or by reason of any waiver, omission of the Guarantied Parties, or any of them, or their failure to proceed promptly or otherwise, or by reason of any action taken or omitted by the Guarantied Parties, or any of them, whether or not such action or failure to act varies or increases the risk of, or affects the rights or remedies of, the Guarantor or by reason of any further dealings between any Borrower, the Guarantied Parties, or any of them, or any other guarantor or surety, and the Guarantor, to the extent permitted by Applicable Law, hereby expressly waives and surrenders any defense to its liability hereunder, or any right of counterclaim or offset of any nature or description which it may have or which may exist based upon, and shall be deemed to have consented to, any of the foregoing acts, omissions, things, agreements or waivers.

7. Set-off. The Guarantied Parties, or any of them, may, without demand or notice of any kind upon or to the Guarantor, at any time or from time to time when any amount shall be due and payable hereunder by the Guarantor, if any Borrower shall not have timely paid its Guarantied Obligations, set off and appropriate any property, balances, credit accounts or moneys of the Guarantor (other than those held in a trust) in the possession of the Guarantied Parties, or any of them, or under the control of any of them for any purpose, which property, balances, credit accounts or moneys shall thereupon be turned over and remitted to the Administrative Agent, to be held and applied to the Guarantied Obligations by the Administrative Agent in accordance with the Loan Agreement, and the Guarantor hereby grants to the Guarantied Parties a security interest in all such property. The Administrative Agent shall give written notice to each of the Borrowers of the exercise of any of the foregoing rights within one (1) Business Day following the exercise thereof.

-3-

way impair or affect this Guaranty or the rights of the Guarantied Parties, or any of them, herein. Anything in this Guaranty to be contrary notwithstanding, it is the intention of the Guarantor and the Guarantied Parties that the Guarantor’s obligations hereunder shall be, but not in excess of, the Maximum Guaranteed Amount. The “Maximum Guaranteed Amount” shall mean the greater of (a) the amount of economic benefit received (directly or indirectly) by the Guarantor pursuant to the Loan Agreement and the other Loan Documents, and (b) the maximum amount which could be paid out by the Guarantor without rendering this Guaranty void or voidable under Applicable Law including, without limitation, (i) Title 11 of the United States Code, as amended, and (ii) applicable state law regarding fraudulent conveyances.

9. Bankruptcy. Upon the bankruptcy or winding up or other distribution of assets of any Borrower or any Restricted Subsidiary of any Borrower or of any surety or guarantor for the Guarantied Obligations, the rights of the Guarantied Parties, or any of them, against the Guarantor shall not be affected or impaired by the omission of the Guarantied Parties, or any of them, to prove its or their claim, as appropriate, and the Guarantied Parties may prove such claims as they see fit and may refrain from proving any claim and in their respective discretion they may value as they see fit or refrain from valuing any security held by the Guarantied Parties, or any of them, without in any way releasing, reducing or otherwise affecting the liability to the Guarantied Parties of the Guarantor.

10. Application of Payments. Any amount received by the Guarantied Parties, or any of them, from whatsoever source and applied toward the payment of the Guarantied Obligations shall be applied in such order of application as is set forth in the Loan Agreement.

11. Waivers by Guarantor. The Guarantor hereby expressly waives, to the extent permitted by Applicable Law: (a) notice of acceptance of this Guaranty, (b) notice of the existence or creation of all or any of the Guarantied Obligations, (c) presentment, demand, notice of dishonor, protest, and all other notices whatsoever and (d) all diligence in collection or protection of or realization upon the Guarantied Obligations or any part thereof, any obligation hereunder, or any security for any of the foregoing. All rights of subrogation, indemnification, contribution and reimbursement against any Borrower, all rights to enforce any remedy the Guarantied Parties, or any of them, may have against any Borrower and any benefit of, or right to participate in, any collateral or security now or hereinafter held by the Guarantied Parties, or any of them, in respect of the Guarantied Obligations, in each case, that the Guarantor may have at any time, are expressly subordinated to the prior payment, observance and performance in full of the Guarantied Obligations and the Guarantor shall withhold exercise of any such right or benefit until the Guarantied Obligations shall have been paid in full and all commitments shall have been terminated. Any money received by the Guarantor in violation of the immediately preceding sentence shall be held in trust by the Guarantor for the benefit of the Guarantied Parties. If a claim is ever made upon the Guarantied Parties, or any of them, for the repayment or recovery of any amount or amounts received by any of them in payment of any of the Guarantied Obligations and such Person repays all or part of such amount by reason of (a) any judgment, decree, or order of any court or administrative body having jurisdiction over such Person or any of its property, or (b) any good faith settlement or compromise of any such claim

-4-

effected by such Person with any such claimant, including the Borrowers, then in such event the Guarantor agrees that any such judgment, decree, order, settlement, or compromise shall be binding upon the Guarantor, notwithstanding any revocation hereof or the cancellation of any promissory note or other instrument evidencing any of the Guarantied Obligations, and the Guarantor shall be and remain obligated to such Person hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by such Person.

12. Assignment by the Guarantied Parties and the Guarantor. To the extent permitted under the Loan Agreement, the Guarantied Parties may each, and without notice of any kind, except as otherwise required by the Loan Agreement, sell, assign or transfer all or any of the Guarantied Obligations. The Guarantor shall not assign its rights or obligations under this Guaranty without the consent of the Administrative Agent, nor shall the Guarantor amend this Guaranty, without the consent of the Majority Lenders. In the event of an assignment permitted hereunder, each and every immediate and successive permitted assignee, transferee, or holder of all or any of the Guarantied Obligations, shall have the right to enforce this Guaranty, by suit or otherwise, for the benefit of such assignee, transferee or holder as fully as if such assignee, transferee or holder were herein by name specifically given such rights, powers and benefits. This Guaranty shall be binding upon the Guarantor, its successors and permitted assigns and inure to the benefit of such successors and assigns.

13. Remedies Cumulative. No delay by the Guarantied Parties, or any of them, in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Guarantied Parties, or any of them, of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action by the Guarantied Parties, or any of them, permitted hereunder shall in any way impair or affect this Guaranty. For the purpose of this Guaranty, the Guarantied Obligations shall include, without limitation, all Guarantied Obligations of all of the Borrowers to the Guarantied Parties notwithstanding any right or power of any third party, individually or in the name of any Borrower or any other Person, to assert any claim or defense as to the invalidity or unenforceability of any such Guarantied Obligation, and no such claim or defense shall impair or affect the obligations of the Guarantor hereunder.

14. Miscellaneous. This is a Guaranty of payment and not of collection. In the event of a demand upon the Guarantor under this Guaranty, the Guarantor shall be held and bound to the Guarantied Parties directly as debtor in respect of the payment of the amounts hereby guaranteed. All reasonable costs and expenses, including, without limitation, attorneys’ fees and expenses, incurred by the Guarantied Parties, or any of them, in obtaining performance of or collecting payments due under this Guaranty shall be deemed part of the Guarantied Obligations guaranteed hereby. Any notice or demand which the Guarantied Parties, or any of them, may wish to give shall be served upon the Guarantor in the fashion prescribed for notices in Section 11.1 of the Loan Agreement in care of the Borrowers at the address for the Borrowers set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and the notice so sent shall be deemed to be served as set forth in Section 11.1 of the Loan Agreement.

-5-

15. GOVERNING LAW. THIS GUARANTY SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN THE STATE OF NEW YORK.

16. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Guaranty, the Guarantor hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Guaranty. The Guarantor hereby agrees, to the extent permitted by Applicable Law that service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrowers, as set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

17. WAIVER OF JURY TRIAL. THE GUARANTOR WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS GUARANTY.

18. Time of the Essence. Time is of the essence with regard to the Guarantor’s performance of its obligations hereunder.

19. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all the Guarantied Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all the Guarantied Parties.

20. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument.

The Borrower shall take or cause to be taken such acts and actions as shall be necessary or appropriate to assure that the Security Interest in the Collateral shall not become subordinate or junior to the security interests, liens or claims of any other Person, and that the Collateral shall not otherwise be or become subject to any Lien, except for Permitted Liens.

The Borrower covenants and agrees that it shall not keep any of such records at any other address, unless written notice thereof is given to the Administrative Agent at least thirty (30) days prior to the creation of any new address for the keeping of such records. The Borrower further agrees that it shall promptly advise the Administrative Agent, in writing making reference to this Section 4 of this Agreement, of the opening of any material new place of business, the closing of any existing material place of business, or any change in the location of the place where it keeps the Collateral or of its chief executive officer.

event be obligated to, upon prior written notice to the Borrower, insure any of the Collateral in such form and amount as the Administrative Agent may deem necessary or desirable if the Borrower fails to obtain insurance as required by the Loan Agreement, and that the Administrative Agent may pay or discharge any taxes if the Borrower fails to pay such taxes as required by the Loan Agreement or Liens (which are not Permitted Liens) on any of the Collateral, and the Borrower agrees to pay any such sum so expended by the Administrative Agent, with interest at the Default Rate, and such amounts shall be deemed to be a part of the Secured Obligations secured by the Collateral under the terms of this Agreement.

7. Covenants Regarding Contracts, Other Contracts and Leases. Except where the failure to do so would not reasonably be expected to cause a Materially Adverse Effect to the Borrowers and the Restricted Subsidiaries taken as a whole, the Borrower shall fulfill, perform and observe each and every material condition and covenant contained in any of the material Contracts, the Other Contracts or the Leases, other than those being contested in good faith or unless the other party thereto is in default. The rights and interests granted to the Administrative Agent hereunder include all of the Borrower’s rights and title (i) to modify the Contracts, the Other Contracts and the Leases, (ii) to terminate the Contracts, the Other Contracts and the Leases, and (iii) to waive or release the performance or observance of any obligation or condition of the Contracts, the Other Contracts and the Leases; provided, however, that the Borrower shall have the right to exercise these rights in a fashion consistent with this Agreement prior to any Event of Default and that these rights shall not be exercised by the Administrative Agent prior to the occurrence and during the continuance of an Event of Default.

8. Remedies.

The Borrower agrees, after the occurrence and during the continuation of an Event of Default, to take any actions that the Secured Parties may reasonably request in order to enable the Administrative Agent to obtain and enjoy the full rights and benefits granted to the Administrative Agent under this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, the Borrower shall, at the Borrower’s cost and expense, use its reasonable best efforts to assist in obtaining all approvals of the FCC which are then required by law for or in connection with any action or transaction contemplated by this Agreement or Article 9 of the UCC as in effect in any applicable jurisdiction, and, at the Administrative Agent’s request, prepare, sign and file with the

The Borrower hereby appoints the Administrative Agent its attorney-in-fact, with power of substitution, to take such action, execute such documents, and perform such work after the occurrence and during the continuation of an Event of Default as the Administrative Agent may deem appropriate in exercise of the rights and remedies granted the Secured Parties, or any of them, herein or in any other Loan Document. The power of attorney granted herein is coupled with an interest and shall be irrevocable.

11. Additional Remedies. Upon the occurrence and during the continuation of an Event of Default, should the Borrower fail to perform or observe any covenant or comply with any condition contained in any of the Contracts, the Other Contracts or the Leases, then the Administrative Agent may, but without obligation to do so and without releasing the Borrower from its obligation to do so, and after written notice to the Borrower, perform such covenant or condition and, to the extent that the Administrative Agent shall incur any reasonable costs or pay any expenses in connection therewith, including any reasonable costs or expenses of litigation associated therewith, such costs, expenses or payments shall be included in the Secured Obligations secured hereby and shall bear interest from the payment of such costs or expenses by the Administrative Agent at the Default Rate. None of the Secured Parties shall be obliged to perform or discharge any obligation of the Borrower under any of the Contracts, the Other Contracts or the Leases.

-7-

12. Administrative Agent May Collect Accounts. The Borrower hereby further appoints the Administrative Agent, effective upon the occurrence and during continuation of an Event of Default as its attorney-in-fact, with power of substitution, with authority to collect all Accounts, to endorse the name of the Borrower on any note, acceptance, check, draft, money order or other evidence of debt or of payment which constitutes a portion of the Collateral and which may come into the possession of the Secured Parties, or any of them, and generally to do such other things and acts in the name of the Borrower with respect to the Collateral as are necessary or appropriate to protect or enforce the rights hereunder of the Secured Parties. The Borrower further authorizes the Administrative Agent, effective upon the occurrence and during the continuation of an Event of Default, to compromise and settle or to sell, assign or transfer or to ask, collect, receive or issue any and all claims possessed by the Borrower which constitute a portion of the Collateral, all in the name of the Borrower. After deducting all reasonable expenses and charges (including the Administrative Agent’s attorneys’ fees) of retaking, keeping, storing and selling the Collateral, the Administrative Agent may apply the proceeds in payment of any of the Secured Obligations in the order of application set forth in the Loan Agreement. The power of attorney granted herein is coupled with an interest and shall be irrevocable. The Borrower agrees that if steps are taken by the Administrative Agent to enforce its rights hereunder, or to realize upon any of the Collateral, the Borrower shall pay to the Administrative Agent the amount of the Administrative Agent’s reasonable costs, including attorneys’ fees, and the Borrower’s obligation to pay such amounts shall be deemed to be a part of the Secured Obligations secured hereunder. Upon the occurrence and during the continuation of an Event of Default, the Borrower shall segregate all proceeds of any Collateral from other assets of the Borrower.

13. Indemnification.

The Borrower further expressly agrees that the Secured Parties shall in no event be under any obligation to resort to any Collateral secured hereby prior to exercising any other rights that the Secured Parties, or any of them, may have against the Borrower or any Subsidiary of the Borrower or any of their respective properties, nor shall the Secured Parties, or any of them, be

-8-

obliged to resort to any other collateral or security for the Secured Obligations, other than the Collateral, prior to any exercise of the Administrative Agent’s rights against the Borrower and its property hereunder.

15. Obligations Commercial in Nature. The Borrower hereby acknowledges that the Obligations arose out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing, the Administrative Agent shall, to the extent permitted by Applicable Law, have the right to immediate possession without notice or a hearing, and hereby knowingly and intelligently waives, to the extent permitted by Applicable Law, any and all rights it may have to any notice and posting of a bond by the Secured Parties, or any of them, prior to seizure by the Administrative Agent or any of its transferees, assigns or successors in interest, of the Collateral or any portion thereof.

None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent or one or more of the Secured Parties in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

In addition to its rights and privileges under this Agreement, the Administrative Agent, on behalf of the Secured Parties, shall have all the rights, powers and privileges of a secured party under the Uniform Commercial Code as in effect in any applicable jurisdiction and other Applicable Law.

6. Return of Ownership Interests to the Pledgor. Upon indefeasible payment in full of all principal and interest on the Notes, full performance by the Borrowers of all Obligations under the Loan Agreement, the Notes, and the other Loan Documents, and satisfaction in full of any other Secured Obligations, other than the Secured Obligations which survive the termination of the Loan Agreement as provided in Section 11.16 of the Loan Agreement, and after such time as the Lenders shall have no obligation to make any further Advances to the Borrowers, this Agreement shall terminate and the Administrative Agent shall return the remaining Ownership Interests and all rights received by the Administrative Agent as a result of its possessory interest in the Ownership Interests to the Pledgor.

7. Disposition of Ownership Interests by Administrative Agent. The Ownership Interests are not registered or qualified under the various federal or state securities laws of the United States and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration. The Pledgor understands that upon such disposition, the Administrative Agent may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Ownership Interests than if the Ownership Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. The Pledgor, therefore, agrees that:

-3-

(a) if the Administrative Agent shall, pursuant to the terms of this Agreement, sell or cause the Ownership Interests or any portion thereof to be sold at a private sale, the Administrative Agent shall have the right to rely upon the advice and opinion of any national brokerage or investment firm having recognized expertise and experience in connection with shares of communications tower companies (but shall not be obligated to seek such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to dispose of the Ownership Interests for sale and as to the best price reasonably obtainable at the private sale thereof; and

(b) that such reliance shall be conclusive evidence that the Administrative Agent has handled such disposition in a commercially reasonable manner absent manifest error.

8. Pledgor’s Obligations Absolute. The obligations of the Pledgor under this Agreement shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against the Pledgor or any other Person, nor against other security or liens available to any Secured Party. The Pledgor hereby waives any right to require that an action be brought against any other Person or to require that resort be had to any other security or to any balance of any deposit account or credit on the books of any of the Secured Parties in favor of any other Person prior to the exercise of remedies hereunder, or to require action hereunder prior to resort by the Administrative Agent to any other security or collateral for the Secured Obligations. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Pledgor or any other obligor with respect to the Secured Obligations to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Pledgor, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral or any other collateral or guaranty to the Pledgor by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof, nor any other act of the Secured Parties, or any of them, shall release the Pledgor from any Secured Obligation hereunder, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Secured Obligation or upon full payment and satisfaction of all Secured Obligations. None of the Secured Parties shall, by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

9. Voting Rights.

(a) For so long as any Secured Obligations remain unpaid, after and during the continuation of an Event of Default, but subject to the provisions of Section 15 hereof, (i) the Administrative Agent may, upon fifteen (15) days’ prior written notice to the Pledgor of its intention to do so, exercise all voting rights, and all other ownership or consensual rights of the Ownership Interests, but under no circumstances is the Administrative Agent obligated by the terms of this Agreement to exercise such rights, and (ii) the Pledgor hereby appoints the

-4-

Administrative Agent, which appointment shall be effective on the fifteenth (15th) day following the giving of notice by the Administrative Agent as provided in Section 9(a)(i) hereof, the Pledgor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote the Ownership Interests in any manner the Administrative Agent deems advisable for or against all matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be. The power-of-attorney granted hereby is coupled with an interest and shall be irrevocable.

(b) For so long as the Pledgor shall have the right to vote the Ownership Interests, the Pledgor covenants and agrees that it will not, without the prior written consent of the Administrative Agent, vote or take any consensual action with respect to the Ownership Interests which would constitute an Event of Default.

10. Amendments and Waivers. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Pledgor or any other obligor to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Pledgor, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Pledgor or any other collateral or guaranty by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof nor any other act of the Secured Parties, or any of them, shall release the Pledgor from any Secured Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Secured Obligation or upon full payment and satisfaction of all Secured Obligations and termination of the Commitments. None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent or one or more of the Secured Parties in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

11. Assignment. The Pledgor hereby agrees that this Agreement or the rights hereunder may, in the discretion of the Secured Parties, or any of them, as applicable, be assigned by the Secured Parties, or any of them, in whole or in part in connection with any assignment of the Loan Agreement or the Obligations arising thereunder, as permitted thereunder. In the event this Agreement or the rights hereunder are so assigned by any of the Secured Parties, the terms “Administrative Agent” or “Secured Parties,” wherever used herein, shall be deemed, as applicable, to refer to and include any such assignee. This Agreement may not be assigned by the Pledgor, but shall apply to and bind the respective successors and permitted assigns of the Pledgor and inure to the benefit of the successors and permitted assigns of the Pledgor.

-5-

13. Governing Law. The provisions of this Agreement shall be construed and interpreted, and all rights and obligations of the parties hereto determined, in accordance with the internal laws of the State of New York applicable to contracts made and to be performed in the State of New York. This Agreement, together with all documents referred to herein, constitutes the entire agreement between the parties with respect to the matters addressed herein and may not be modified except by a writing executed by the Administrative Agent and the Pledgor and delivered by the Administrative Agent to the Pledgor.

14. Severability. If any paragraph or part thereof shall for any reason be held or adjudged to be invalid, illegal or unenforceable by any court of competent jurisdiction, to the extent permitted by law, such paragraph or part thereof so adjudicated invalid, illegal or unenforceable shall be deemed separate, distinct and independent, and the remainder of this Agreement shall remain in full force and effect and shall not be affected by such holding or adjudication.

15. FCC Compliance. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Administrative Agent which may require the consent or approval of the FCC, and the proxy granted in Section 9(a) hereof shall not become effective, unless and until all requirements of the Communications Act requiring the consent to or approval of such action by the FCC have been satisfied. The Pledgor covenants that, following and during the continuance of an Event of Default, upon request of the Administrative Agent, it will cause to be filed such applications and take such other action as may be reasonably requested by the Administrative Agent to obtain consent or approval of the FCC to any action contemplated by this Agreement and to give effect to the security interest of the Administrative Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Communications Act.

16. Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument.

17. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all of the Secured Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all of the Secured Parties.

18. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Agreement, the Pledgor hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement. The Pledgor hereby agrees, to the extent permitted by Applicable Law that service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrowers, as set forth in or otherwise provided pursuant to Section 11.1 of the Loan

-6-

Agreement, and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

19. WAIVER OF JURY TRIAL. THE PLEDGOR WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS AGREEMENT.

Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned thereto in the Loan Agreement (as defined herein).

WITNESSETH:

WHEREAS, American Tower, L.P., a Delaware limited partnership (“AT LP”), American Towers, Inc., a Delaware corporation (“AT Inc.”), American Tower International, Inc., a Delaware corporation (“AT International”) and American Tower LLC, a Delaware limited liability company (collectively, with AT LP, AT Inc. and AT International, the “Borrowers”), the Lenders (as defined therein), the Issuing Bank (as defined therein) and Toronto Dominion (Texas), Inc., as administrative agent thereunder (the “Administrative Agent”, and collectively with the Lenders and the Issuing Bank, the “Guarantied Parties”) are all parties to that certain Loan Agreement dated as of May 24, 2004 (as amended, modified, restated or supplemented from time to time, the “Loan Agreement”); and

NOW, THEREFORE, in consideration of the above premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Guarantor hereby agrees, for the benefit of the Guarantied Parties, as follows:

1. Payment. The Guarantor hereby unconditionally guarantees to the Guarantied Parties full and prompt payment when due whether at maturity, by acceleration or otherwise of all Obligations under the Loan Agreement (collectively referred to herein as the “Guarantied Obligations”).

3. Guaranty Final. Upon the execution and delivery of this Guaranty to the Administrative Agent, this Guaranty shall be deemed to be finally executed and delivered by the Guarantor and shall not be subject to or affected by any promise or condition affecting or limiting the Guarantor’s liability and no statement, representation, agreement or promise on the part of the Guarantied Parties, the Borrowers, or any of them, or any officer, employee or agent thereof, unless contained herein forms any part of this Guaranty or has induced the making hereof or shall be deemed in any way to affect the Guarantor’s liability hereunder.

5. Dealings with Guarantor. The Guarantied Parties, or any of them, may, from time to time, without exonerating or releasing the Guarantor in any way under this Guaranty, (i) take such further or other security or securities for the Guarantied Obligations or any part thereof as the Guarantied Parties, or any of them, may deem proper, consistent with the Loan Agreement, or (ii) release, discharge, abandon or otherwise deal with or fail to deal with any guarantor of the Guarantied Obligations or any security or securities therefor or any part thereof now or hereafter held by the Guarantied Parties, or any of them, or (iii) consistent with the Loan Agreement, amend, modify, extend, accelerate or waive in any manner any of the provisions, terms, or conditions of any of the Loan Documents, all as the Guarantied Parties, or any of them, may consider expedient or appropriate in their sole discretion.

7. Set-off.

contribution and reimbursement against the Borrowers, all rights to enforce any remedy the Guarantied Parties, or any of them, may have against the Borrowers and any benefit of, or right to participate in, any collateral or security now or hereinafter held by the Guarantied Parties, or any of them, in respect of the Guarantied Obligations, in each case, that the Guarantor may have at any time, are expressly subordinated to the prior payment, observance and performance in full of the Guarantied Obligations and the Guarantor shall withhold exercise of any such right or benefit until the Guarantied Obligations shall have been paid in full and all Commitments shall have been terminated. Any money received by the Guarantor in violation of the immediately preceding sentence shall be held in trust by the Guarantor for the benefit of the Guarantied Parties. If a claim is ever made upon the Guarantied Parties, or any of them, for the repayment or recovery of any amount or amounts received by any of them in payment of any of the Guarantied Obligations and such Person repays all or part of such amount by reason of (a) any judgment, decree, or order of any court or administrative body having jurisdiction over such Person or any of its property, or (b) any good faith settlement or compromise of any such claim effected by such Person with any such claimant, including, without limitation, the Borrowers, then in such event the Guarantor agrees that any such judgment, decree, order, settlement, or compromise shall be binding upon the Guarantor, notwithstanding any revocation hereof or the cancellation of any promissory note or other instrument evidencing any of the Guarantied Obligations, and the Guarantor shall be and remain obligated to such Person hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by such Person.

In the event of an assignment permitted hereunder, each and every immediate and successive permitted assignee, transferee, or holder of all or any of the Guarantied Obligations, shall have the right to enforce this Guaranty, by suit or otherwise, for the benefit of such assignee, transferee or holder as fully as if such assignee, transferee or holder were herein by name specifically given such rights, powers and benefits. This Guaranty shall be binding upon the Guarantor, its successors and permitted assigns and inure to the benefit of such successors and assigns.

12. Remedies Cumulative. No delay by the Guarantied Parties, or any of them, in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Guarantied Parties, or any of them, of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action by the Guarantied Parties, or any of them, permitted hereunder shall in any way impair or affect this Guaranty. For the purpose of this Guaranty, the Guarantied Obligations shall include, without limitation, all Guarantied Obligations of the Borrowers to the Guarantied Parties notwithstanding any right or power of any third party, individually or in the name of any of the Borrowers or any other Person, to assert any claim or defense as to the invalidity or unenforceability of any such Guarantied Obligation, and no such claim or defense shall impair or affect the obligations of the Guarantor hereunder.

-4-

13. Miscellaneous. This is a Guaranty of payment and not of collection. In the event of a demand upon the Guarantor under this Guaranty, the Guarantor shall be held and bound to the Guarantied Parties directly as debtor in respect of the payment of the amounts hereby guaranteed. All reasonable costs and expenses, including, without limitation, attorneys’ fees and expenses, incurred by the Guarantied Parties, or any of them, in obtaining performance of or collecting payments due under this Guaranty shall be deemed part of the Guarantied Obligations guaranteed hereby. Any notice or demand which the Guarantied Parties, or any of them, may wish to give shall be served upon the Guarantor in the fashion prescribed for notices in Section 11.1 of the Loan Agreement in care of the Borrowers at the address for the Borrowers set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and the notice so sent shall be deemed to be served as set forth in Section 11.1 of the Loan Agreement.

14. Visits and Inspections. The Guarantor covenants and agrees that so long as any amount is owing on account of Guarantied Obligations or otherwise pursuant to this Guaranty, the Guarantor shall permit representatives of the Guarantied Parties, or any of them, to visit and inspect properties of the Guarantor during normal business hours after reasonable notice, inspect the Guarantor’s books and records and discuss with the principal officers of the Guarantor its businesses, assets, liabilities, financial positions, results of operations and business prospects.

15. Governing Law. This Guaranty shall be construed in accordance with and governed by the internal laws of the State of New York applicable to contracts made and to be performed in the State of New York.

17. WAIVER OF JURY TRIAL. THE GUARANTOR WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS GUARANTY.

18. Time of the Essence. Time is of the essence with regard to the Guarantor’s performance of its obligations hereunder.

19. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all the Guarantied Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of the Guarantied Parties.

WHEREAS, the Pledgor is the sole stockholder of AT Inc. and, as such, will derive substantial economic benefit from the making of the Loans (as defined in the Loan Agreement) to the Borrowers; and

WHEREAS, the Pledgor has executed that certain Parent Guaranty dated as of even date herewith pursuant to the Loan Agreement (the “Guaranty”), and as a condition precedent to the effectiveness of the Loan Agreement, the Pledgor is required to execute and deliver this Agreement; and

WHEREAS, to secure the payment by the Borrowers of their Obligations arising under the Loan Agreement, the Pledgor and the Administrative Agent (on behalf of the Secured Parties) have agreed that the shares of Capital Stock and other ownership interests, including, without limitation, any limited liability company and limited partnership interests (the “Ownership Interests”) owned by the Pledgor in each of the Subsidiaries of the Pledgor listed on Schedule 1 attached hereto (each a “Subsidiary” and collectively, the “Subsidiaries”) shall be pledged by the Pledgor to the Administrative Agent (on behalf of the Secured Parties) to secure the Guarantied Obligations (as defined in the Guaranty);

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Warranty. The Pledgor hereby represents and warrants to the Secured Parties that (a) except for the security interest created hereby, the Pledgor owns the Ownership Interests, which constitutes the percentage of the issued and outstanding ownership interests of the Subsidiaries as set forth on Schedule 1 attached hereto, free and clear of all Liens, (b) the shares of Capital Stock pledged hereunder are duly issued, fully paid and non-assessable, and (c) the Pledgor has the unencumbered right to pledge the Ownership Interests. In addition, Pledgor represents and covenants as follows: (1) upon possession and retention of the certificates evidencing Ownership Interests that are “securities” within the meaning of Article 8 of the Uniform Commercial Code (“UCC”) (such Ownership Interests hereinafter referred to as “Certificated Ownership Interests”) by the Administrative Agent, the Administrative Agent shall have a valid and perfected first priority security interest (other than Permitted Liens having priority) in such Ownership Interests and (2) upon the filing of all required UCC financing statements, the Administrative Agent shall have a first priority security interest (other than Permitted Liens having priority) in all the other Ownership Interests, in each case, securing the payment of the Guarantied Obligations.

2. Security Interest. The Pledgor hereby unconditionally grants and assigns to the Administrative Agent, on behalf of the Secured Parties, and their respective successors and assigns, a continuing security interest in and security title to the Ownership Interests of the Subsidiaries obtained by the Pledgor in the future, and in each case, all certificates representing such Ownership Interests, all rights, options, warrants, stock or other securities or other property which may hereafter be received, receivable or distributed in respect of the Ownership Interests, together with all proceeds of the foregoing, including, without limitation, all dividends, cash, notes, securities or other property from time to time acquired, receivable or otherwise distributed in respect of, or in exchange for, the foregoing, all of which shall constitute “Ownership Interests” hereunder. The Pledgor has delivered to the Administrative Agent herewith all of its right, title and interest in and to the Ownership Interests, together with certificates with respect to Certificated Ownership Interests, and undated stock powers endorsed in blank with respect to Certificated Ownership Interests, as security for the payment of all of the obligations of the Pledgor to the Secured Parties, or any of them, under this Agreement and the Guaranty and any extensions, renewals or amendments of any of the foregoing, however created, acquired, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, or due or to become due; it being the intention of the parties hereto that beneficial ownership of the Ownership Interests, including, without limitation, all voting, consensual and dividend rights, shall remain in the Pledgor until the occurrence and during the continuance of an Event of Default and until the Administrative Agent shall notify the Pledgor of the Administrative Agent’s exercise of voting and dividend rights to the Ownership Interests pursuant to Section 9 hereof.

3. Additional Ownership Interests. In the event that, during the term of this Agreement:

(a) any stock dividend, stock split, reclassification, readjustment, or other change is declared or made in the capital structure of any Subsidiary, or any new ownership interest are issued by such Subsidiary, or any new Subsidiary of the Pledgor which is a Borrower under the Loan Agreement is formed or acquired, all new, substituted, and additional ownership interests shall be issued to the Pledgor and, if a “certificated security” (as defined in Section 8-

-2-

102 of the UCC as in effect in the State of New York), shall be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank by the Pledgor with respect to any such Certificated Ownership Interests, and shall thereupon constitute Ownership Interests to be held by the Administrative Agent under the terms of this Agreement; and

(b) any subscriptions, warrants or any other rights or options shall be issued in connection with the Ownership Interests consisting of shares of Capital Stock, all new stock or other securities acquired through such subscriptions, warrants, rights or options by the Pledgor shall, if a “certificated security” (as defined in Section 8-102 of the UCC as in effect in the State of New York), be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank, and shall thereupon constitute Ownership Interests to be held by the Administrative Agent under the terms of this Agreement.

4. Default. In the event of the occurrence of an Event of Default and so long as any such Event of Default is continuing, the Administrative Agent may sell or otherwise dispose of the Ownership Interests at a public or private sale or make other commercially reasonable disposition of the Ownership Interests or any portion thereof after fifteen (15) days’ notice to the Pledgor and the Secured Parties, or any of them, may purchase the Ownership Interests or any portion thereof at any public sale. The proceeds of the public or private sale or other disposition shall be applied first to the costs of the Administrative Agent incurred in connection with the sale, expressly including, without limitation, any costs under Section 7 hereof, and then as provided in the Loan Agreement. In the event the proceeds of the sale or other disposition of the Ownership Interests are insufficient to satisfy the Guarantied Obligations, the Pledgor shall remain liable for any such deficiency to the extent provided in the Guaranty. The Pledgor waives, to the extent permitted by Applicable Law, the rights of equity of redemption, appraisal, notice of acceptance, presentment, demand and marshalling, to the extent applicable.

5. Additional Rights of Secured Party. In addition to its rights and privileges under this Agreement, the Administrative Agent, on behalf of the Secured Parties, shall have all the rights, powers and privileges of a secured party under the UCC as in effect in any applicable jurisdiction and other Applicable Law.

6. Return of Ownership Interests to the Pledgor. Upon indefeasible payment in full of all principal and interest on the Notes, full performance by the Borrowers of all Obligations under the Loan Agreement and the other Loan Documents, and satisfaction in full of any other Guarantied Obligations, other than the Guarantied Obligations which survive the termination of the Loan Agreement as provided in Section 11.16 of the Loan Agreement, and after such time as the Lenders shall have no obligation to make any further Advances to the Borrowers, this Agreement shall terminate and the Administrative Agent shall return the remaining Ownership Interests and all rights received by the Administrative Agent as a result of its possessory interest in the Ownership Interests to the Pledgor.

-3-

that upon such disposition, the Administrative Agent may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Ownership Interests than if the Ownership Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. The Pledgor, therefore, agrees that:

(b) that such reliance shall be conclusive evidence that the Administrative Agent has handled such disposition in a commercially reasonable manner absent manifest error.

8. Pledgor’s Obligations Absolute. The obligations of the Pledgor under this Agreement shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against the Borrowers or any other Person, nor against other security or liens available to any Secured Party. The Pledgor hereby waives any right to require that an action be brought against any other Person or to require that resort be had to any other security or to any balance of any deposit account or credit on the books of any of the Secured Parties in favor of any other Person prior to the exercise of remedies hereunder, or to require action hereunder prior to resort by the Administrative Agent to any other security or collateral for the Guarantied Obligations. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Pledgor or any other obligor with respect to the Guarantied Obligations to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Borrowers, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Borrowers or any other Person or any other collateral or guaranty to the Borrowers or any other Person by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof, nor any other act of the Secured Parties, or any of them, shall release the Pledgor from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations. None of the Secured Parties shall, by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

-4-

9. Voting Rights.

(a) For so long as any Guarantied Obligations remain unpaid, after and during the continuation of an Event of Default, (i) the Administrative Agent may, upon fifteen (15) days’ prior written notice to the Pledgor of its intention to do so, exercise all voting rights, and all other ownership or consensual rights of the Ownership Interests, but under no circumstances is the Administrative Agent obligated by the terms of this Agreement to exercise such rights, and (ii) the Pledgor hereby appoints the Administrative Agent, which appointment shall be effective on the fifteenth (15th) day following the giving of notice by the Administrative Agent as provided in Section 9(a)(i) hereof, the Pledgor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote the Ownership Interests in any manner the Administrative Agent deems advisable for or against all matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be. The power-of-attorney granted hereby is coupled with an interest and shall be irrevocable.

10. Amendments and Waivers. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Pledgor or any other obligor to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Pledgor, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Pledgor or any other collateral or guaranty by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof nor any other act of the Secured Parties, or any of them, shall release the Pledgor from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations and termination of the Commitments. None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent or one or more of the Secured Parties in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

-5-

shall be deemed, as applicable, to refer to and include any such assignee. This Agreement may not be assigned by the Pledgor, but shall apply to and bind the respective successors and permitted assigns of the Pledgor and inure to the benefit of the successors and permitted assigns of the Pledgor.

12. Notices. All notices and other communications required or permitted hereunder shall be in writing, and shall be given in the manner and at the addresses set forth in Section 11.1 of the Loan Agreement, and with respect to the Pledgor, at the address for the Borrowers set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement.

15. FCC Compliance. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Administrative Agent which may require the consent or approval of the FCC, and the proxy granted in Section 9(a) hereof shall not become effective, unless and until all requirements of the Communications Act, requiring the consent to or approval of such action by the FCC have been satisfied. The Pledgor covenants that, following and during the continuance of an Event of Default, upon request of the Administrative Agent, it will cause to be filed such applications and take such other action as may be reasonably requested by the Administrative Agent to obtain consent or approval of the FCC to any action contemplated by this Agreement and to give effect to the security interest of the Administrative Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Communications Act.

17. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Agreement, the Pledgor hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement.

-6-

The Pledgor hereby agrees, to the extent permitted by Applicable Law that service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrowers, as set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

18. WAIVER OF JURY TRIAL. THE PLEDGOR WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS AGREEMENT.

19. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all of the Secured Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all of the Secured Parties.

20. Further Assurances. The Pledgor hereby authorizes the Administrative Agent to file such financing statements and such other documents as the Administrative Agent may reasonably require to protect or perfect the interest of the Secured Parties in the Ownership Interests, and the Pledgor further irrevocably appoints the Administrative Agent as its attorney-in-fact, with a power of attorney to execute on behalf of the Pledgor such UCC financing statement forms as the Administrative Agent may from time to time reasonably deem necessary or desirable to protect or perfect such interest in the Ownership Interests. Such power of attorney is coupled with an interest and shall be irrevocable. In addition, the Pledgor agrees to do, execute and deliver or cause to be done, executed and delivered all such further acts, documents and things as the Administrative Agent may reasonably require for the purpose of perfecting or protecting the rights of the Secured Parties hereunder or otherwise giving effect to this Agreement, all promptly upon request therefor.

7. Set-off. The Guarantied Parties, or any of them, may, without demand or notice of any kind upon or to the Guarantor, at any time or from time to time when any amount shall be due and payable hereunder by the Guarantor, if the Borrowers shall not have timely paid their Guarantied Obligations, set off and appropriate any property, balances, credit accounts or moneys of the Guarantor (other than those held in a trust) in the possession of the Guarantied Parties, or any of them, or under the control of any of them for any purpose, which property, balances, credit accounts or moneys shall thereupon be turned over and remitted to the Administrative Agent, to be held and applied to the Guarantied Obligations by the Administrative Agent in accordance with the Loan Agreement, and the Guarantor hereby grants to the Guarantied Parties, a security interest in all such property.

This Guaranty shall be binding upon the Guarantor, its successors and permitted assigns and inure to the benefit of such successors and assigns.

13. Remedies Cumulative. No delay by the Guarantied Parties, or any of them, in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Guarantied Parties, or any of them, of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action by the Guarantied Parties, or any of them, permitted hereunder shall in any way impair or affect this Guaranty.

The Subsidiary further agrees that it shall promptly advise the Administrative Agent, in writing making reference to this Section 5 of this Agreement, of the opening of any material new place of business, the closing of

any existing material place of business, or any change in the location of the place where it keeps the Collateral or of its chief executive officer.

6. Collateral Not Fixtures. The parties intend that, to the extent permitted by Applicable Law, the Collateral, including, without limitation, all communications towers, shall remain personal property irrespective of the manner of its attachment or affixation to realty.

7. Covenants Regarding Collateral. Any and all injury to, or loss or destruction of, the Collateral shall be at the Subsidiary’s risk, and shall not release the Subsidiary from its obligations hereunder. The Subsidiary agrees not to sell, transfer, assign, dispose of, mortgage, grant a security interest in, or encumber any of the Collateral except as permitted under the Loan Agreement. The Subsidiary agrees to maintain in force such insurance with respect to the Collateral as is required under the Loan Agreement. The Subsidiary agrees to pay all required taxes, liens, and assessments upon the Collateral, its use or operation, as required under the Loan Agreement. The Subsidiary further agrees that the Administrative Agent may, but shall in no event be obligated to, following written notice to the Subsidiary, insure any of the Collateral in such form and amount as the Administrative Agent may deem necessary or desirable if the Subsidiary fails to obtain insurance as required by the Loan Agreement, and that the Administrative Agent may pay or discharge any taxes if the Subsidiary fails to pay such taxes as required by the Loan Agreement or Liens (which are not Permitted Liens) on any of the Collateral, and the Subsidiary agrees to pay any such sum so expended by the Administrative Agent, with interest at the Default Rate, and such amounts shall be deemed to be a part of the Guarantied Obligations secured by the Collateral under the terms of this Agreement.

8. Covenants Regarding Contracts, Other Contracts and Leases. Except where the failure to do so would not reasonably be expected to cause a Materially Adverse Effect to the Borrowers and the Restricted Subsidiaries taken as a whole, the Subsidiary shall fulfill, perform and observe each and every material condition and covenant contained in any of the material Contracts, the Other Contracts or the Leases, other than those being contested in good faith or unless the other party thereto is in default. The rights and interests granted to the Administrative Agent hereunder include all of the Subsidiary’s rights and title (i) to modify the Contracts, the Other Contracts and the Leases, (ii) to terminate the Contracts, the Other Contracts and the Leases, and (iii) to waive or release the performance or observance of any obligation or condition of the Contracts, the Other Contracts and the Leases; provided, however, that the Subsidiary shall have the right to exercise these rights in a fashion consistent with this Agreement prior to any Event of Default and at any time that an Event of Default is not continuing and that these rights shall not be exercised by the Administrative Agent prior to the occurrence and during the continuation of an Event of Default.

9. Remedies. Upon the occurrence and during the continuation of an Event of Default, the Secured Parties shall have such rights and remedies as are set forth in the Loan Agreement, the other Loan Documents and herein, all the rights, powers and privileges of a secured party under the Uniform Commercial Code of the State of New York and any other applicable jurisdiction, and all other rights and remedies available to the Secured Parties, or any of them, at law or in equity. The Subsidiary covenants and agrees that any notification of intended disposition of any Collateral, if such notice is required by law, shall be deemed reasonably and properly given if given in the manner provided for in Section 19 hereof at least

ten (10) days prior to such disposition. Under such circumstances, the Secured Parties shall have the right to request the appointment of a receiver for the properties and assets of the Subsidiary, and the Subsidiary hereby consents to such right and to such appointment and hereby waives any objection it may have thereto and hereby waives the right to have a bond or other security posted by the Administrative Agent or any other Person in connection therewith. The Subsidiary agrees, after the occurrence of an Event of Default and during the continuation of an Event of Default, to take any actions that the Secured Parties may reasonably request in order to enable the Administrative Agent to obtain and enjoy the full rights and benefits granted to the Administrative Agent under this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, the Subsidiary shall, at the Subsidiary’s cost and expense, use its reasonable best efforts to assist in obtaining all approvals of the FCC which are then required by law for or in connection with any action or transaction contemplated by this Agreement or Article 9 of the UCC as in effect in any applicable jurisdiction, and, at the Administrative Agent’s request, prepare, sign and file with the FCC the assignor’s or transferor’s portion of any application or applications for consent to the assignment of the Licenses or transfer of control thereof necessary or appropriate under the FCC’s rules for approval of any sale or transfer of the Administrative Agent’s remedies under this Agreement. The Administrative Agent shall have the right, in connection with the issuance of any order for relief in a bankruptcy proceeding, to petition the bankruptcy court for the transfer of control or assignment of the Collateral to a receiver, trustee, transferee, or similar official or to any purchaser of the Collateral pursuant to any public or private sale, foreclosure or other exercise of remedies available to the Administrative Agent, all as permitted by Applicable Law. All amounts realized or collected through the exercise of remedies hereunder shall be applied to the Guarantied Obligations as provided in the Loan Agreement.

10. Notification of Account Debtors. Upon the occurrence and during the continuation of an Event of Default, the Administrative Agent may notify the account debtors that all payments with respect to Accounts are to be paid directly to the Administrative Agent and any amount thereafter paid to the Subsidiary shall be received in trust by the Subsidiary for the benefit of the Administrative Agent and segregated from other funds of the Subsidiary and paid over to the Administrative Agent in the form received (together with any necessary endorsements).

11. Remedies of Administrative Agent. Upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent or its designee may proceed to perform any and all of the obligations of the Subsidiary contained in any of the Contracts, Other Contracts or Leases and exercise any and all rights of the Subsidiary therein contained as fully as the Subsidiary itself could. The Subsidiary hereby appoints the Administrative Agent its attorney-in-fact, with power of substitution, to take such action, execute such documents, and perform such work after the occurrence and during the continuation of an Event of Default, as the Administrative Agent may deem appropriate in exercise of the rights and remedies granted the Secured Parties, or any of them, herein or in any other Loan Document following written notice to the Subsidiary. The powers herein granted shall include, without limitation, powers to: (a) sue on the Contracts, the Other Contracts or the Leases; (b) seek all governmental approvals (other than FCC approvals) required for the operation of the business of the Subsidiary; (c) modify or terminate the Contracts, the Other Contracts and the Leases; and (d) waive or release the performance or observance of any obligation under any of the Contracts, Other

Contracts or Leases. The power of attorney granted herein is coupled with an interest and shall be irrevocable.

12. Additional Remedies. Upon the occurrence of an Event of Default and during the continuation thereof, should the Subsidiary fail to perform or observe any covenant or comply with any condition contained in any of the Contracts, the Other Contracts or the Leases, then following written notice to the Subsidiary, the Administrative Agent may, but without obligation to do so and without releasing the Subsidiary from its obligation to do so, perform such covenant or condition and, to the extent that the Administrative Agent shall incur any reasonable costs or pay any expenses in connection therewith, including, without limitation, any reasonable costs or expenses of litigation associated therewith, such costs, expenses or payments shall be included in the Guarantied Obligations secured hereby and shall bear interest from the payment of such costs or expenses by the Administrative Agent at the Default Rate. None of the Secured Parties shall be obliged to perform or discharge any obligation of the Subsidiary under any of the Contracts, the Other Contracts or the Leases, and, except as may result from the bad faith, gross negligence or willful misconduct of the Person seeking indemnification, the Subsidiary agrees to indemnify and hold each Secured Party harmless against any and all liability, loss or damage which any such Person may incur under any of the Contracts, the Other Contracts or the Leases or under or by reason of this Agreement, and any and all claims and demands whatsoever which may be asserted against the Subsidiary by reason of an act of any Secured Party under any of the terms of this Agreement or under the Contracts, the Other Contracts or the Leases.

13. Administrative Agent May Collect Accounts. The Subsidiary hereby further appoints the Administrative Agent as its attorney-in-fact, with power of substitution, with authority to collect all Accounts, to endorse the name of the Subsidiary on any note, acceptance, check, draft, money order or other evidence of debt or of payment which constitutes a portion of the Collateral and which may come into the possession of the Secured Parties, or any of them, and generally to do such other things and acts in the name of the Subsidiary with respect to the Collateral as are necessary or appropriate to protect or enforce the rights hereunder of the Secured Parties after the occurrence and during the continuation of an Event of Default. The Subsidiary further authorizes the Administrative Agent, effective upon the occurrence of an Event of Default and during the continuation thereof, to compromise and settle or to sell, assign or transfer or to ask, collect, receive or issue any and all claims possessed by the Subsidiary which constitute a portion of the Collateral, all in the name of the Subsidiary. After deducting all reasonable expenses and charges (including, without limitation, the Administrative Agent’s attorneys’ fees) of retaking, keeping, storing and selling the Collateral, the Administrative Agent may apply the proceeds in payment of any of the Guarantied Obligations in the order of application set forth in the Loan Agreement. The power of attorney granted herein is coupled with an interest and shall be irrevocable. The Subsidiary agrees that a failure to so notify the Administrative Agent shall be a waiver and bar to any subsequent claim for any such property. The Subsidiary agrees that if steps are taken by the Administrative Agent to enforce its rights hereunder, or to realize upon any of the Collateral, the Subsidiary shall pay to the Administrative Agent the amount of the Administrative Agent’s reasonable costs, including, without limitation, attorneys’ fees, and the Subsidiary’s obligation to pay such amounts shall be deemed to be a part of the Guarantied Obligations secured hereunder. Upon the occurrence and during the continuation of an Event of Default, the Subsidiary shall segregate all proceeds of any Collateral from other assets of the Subsidiary.

14. Indemnification. The Subsidiary shall indemnify and hold harmless each Secured Party and any other Person acting hereunder for all losses, costs, damages, fees and expenses whatsoever associated with the exercise of the powers of attorney granted herein and shall release each Secured Party and any other Person acting hereunder from all liability whatsoever for the exercise of the foregoing powers of attorney and all actions taken pursuant thereto, except, in either event, in the case of bad faith, gross negligence or willful misconduct by the Person seeking indemnification.

15. Remedies Cumulative. The Subsidiary agrees that the rights of the Secured Parties, or any of them, under this Agreement, the Loan Agreement, any other Loan Document, or any other contract or agreement now or hereafter in existence among the Secured Parties and the Subsidiary and the other obligors thereunder, or any of them, shall be cumulative, and that each Secured Party may from time to time exercise such rights and such remedies as such Person or Persons may have thereunder and under the laws of the United States or any state, as applicable, in the manner and at the time that such Person or Persons in its or their sole discretion desire, subject to the terms of such agreements. The Subsidiary further expressly agrees that the Secured Parties shall in no event be under any obligation to resort to any Collateral secured hereby prior to exercising any other rights that the Secured Parties, or any of them, may have against the Subsidiary or its property, nor shall the Secured Parties be obliged to resort to any other collateral or security for the Guarantied Obligations, other than the Collateral, prior to any exercise of the Administrative Agent’s rights against the Subsidiary and its property hereunder.

16. Obligations Commercial in Nature. The Subsidiary hereby acknowledges that the Guarantied Obligations arose out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing, the Administrative Agent shall, to the extent permitted by Applicable Law, have the right to immediate possession without notice or a hearing, and hereby knowingly and intelligently waives, to the extent permitted by Applicable Law, any and all rights it may have to any notice and posting of a bond by the Secured Parties, or any of them, prior to seizure by the Administrative Agent or any of its transferees, assigns or successors in interest of the Collateral or any portion thereof.

17. Amendments and Waivers. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreements or of any other Loan Document, or of any instrument or document executed and delivered by the Subsidiary or any other obligor to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Borrowers, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Subsidiary by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof, nor any other act of the Secured Parties, or any of them, shall release the Subsidiary from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations and termination of the Commitment. None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any

right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

18. Assignment. The Subsidiary agrees that this Agreement or the rights hereunder may, in the discretion of the Secured Parties, or any of them, as applicable, be assigned by the Secured Parties, or any of them, in whole or in part in connection with any assignment of the Loan Agreement or the Obligations arising thereunder, as permitted thereunder. In the event this Agreement or the rights hereunder are so assigned by any of the Secured Parties, the terms “Secured Parties” or “Administrative Agent” wherever used herein shall be deemed, as applicable, to refer to and include any such assignee. This Agreement may not be assigned by the Subsidiary without the consent of the Administrative Agent, but shall apply to and bind the respective successors and permitted assigns of the Subsidiary and inure to the benefit of the successors and permitted assigns of the Subsidiary.

19. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be given in a fashion prescribed in Section 11.1 of the Loan Agreement with respect to the Secured Parties, and in the fashion prescribed in Section 11.1 of the Loan Agreement with respect to the Subsidiary to the address of the Borrowers set forth in or otherwise provided pursuant to the Loan Agreement.

20. Governing Law. The provisions of this Agreement shall be construed and interpreted, and all rights and obligations of the parties hereto determined, in accordance with the internal laws of the State of New York applicable to contracts made and to be performed in the State of New York. This Agreement, together with all documents referred to herein, constitutes the entire agreement among the Subsidiary and the Secured Parties with respect to the matters addressed herein and may not be modified except by a writing executed by the Administrative Agent and delivered to the Subsidiary.

22. FCC Compliance. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Administrative Agent which may require the consent or approval of the FCC, unless and until all requirements of Applicable Law, including, without limitation any required approval under the Communications Act, requiring the consent to or approval of such action by the FCC or any governmental or other authority have been satisfied. The Subsidiary covenants that, following and during the continuation of an Event of Default, upon request of the Administrative Agent, it will cause to be filed such applications and take such other action as may be reasonably requested by the Administrative Agent to obtain consent or approval of the FCC to any action contemplated by this Agreement and to give effect to the security interest of the Administrative Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Communications Act.

24. Changes in Applicable Law. The parties acknowledge their intent that, upon the occurrence of an Event of Default and during the continuance thereof, the Administrative Agent shall receive, to the fullest extent permitted by Applicable Law and governmental policy (including, without limitation, the rules, regulations and policies of the FCC), all rights necessary or desirable to obtain, use or sell the Collateral and to exercise all remedies available to it under this Agreement, the UCC as in effect in any applicable jurisdiction, or other Applicable Law. The parties further acknowledge and agree that, in the event of changes in law or governmental policy occurring subsequent to the date hereof that affect in any manner the Administrative Agent’s rights of access to, or use or sale of, the Collateral, or the procedures necessary to enable the Administrative Agent to obtain such rights of access, use or sale, the Administrative Agent and the Subsidiary shall amend this Agreement in such manner as the Administrative Agent shall reasonably request in order to provide the Administrative Agent such rights to the greatest extent possible consistent with Applicable Law and governmental policy.

25. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all the Secured Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all the Secured Parties.

26. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Agreement, the Subsidiary hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement. The Subsidiary hereby agrees, to the extent permitted by Applicable Law that service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrowers, as set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

27. WAIVER OF JURY TRIAL. THE SUBSIDIARY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS AGREEMENT.

with the interests so assigned until (a) the Administrative Agent shall have received a copy of this Assignment and Assumption Agreement duly executed by the Assignor, the Assignee, and the Borrowers (to the extent required under the Loan Agreement), and shall have received the assignment fee described in Section 11.5(c)(iii) of the Loan Agreement, and (b) the Assignor shall have delivered to the Administrative Agent its promissory notes. From and after the date (the “Effective Date”) on which the Administrative Agent shall notify the Borrowers, the Assignee and the Assignor that (a) and (b) have occurred and all consents (if any) required have been given, the Assignee shall be deemed to be a party to the Loan Agreement and, to the extent that rights and obligations thereunder shall have been assigned to Assignee as provided herein, shall have the rights and obligations of a Lender under the Loan Agreement. After the Effective Date, and with respect to all such amounts accrued from the Assignment Date, (i) all interest, principal, fees, and other amounts that would otherwise be payable to the Assignor in respect of the Assigned Loans or the Assigned Commitments shall be paid to the Assignee, (ii) if the Assignor receives any payment on account of the Assigned Loans or the Assigned Commitments that is payable to the Assignee, the Assignor shall promptly deliver such payment to the Assignee, and (iii) if the Assignee receives any payment in respect of Obligations of the Borrowers accrued prior to the Effective Date, then the Assignee shall pay over the same to the Assignor. The Assignee agrees to deliver to the Borrowers and the Administrative Agent on or before the Effective Date such Internal Revenue Service forms as may be required to establish that the Assignee is entitled to receive payments under the Loan Agreement without deduction or withholding of tax.

6. Authorization; Independent Investigation. The Assignee acknowledges that it is purchasing the Assigned Loans and the Assigned Commitments from the Assignor without recourse and, except as provided in Section 3 hereof, without representation or warranty. The Assignee further acknowledges that it has made its own independent investigation and credit evaluation of the Borrowers in connection with its purchase of the Assigned Loans and the Assigned Commitments and has received copies of all Loan Documents that it has requested. Except for the representations or warranties set forth in Section 3 hereof, the Assignee acknowledges that it is not relying on any representation or warranty of the Assignor, expressed or implied, including without limitation, any representation or warranty relating to the legality, validity, genuineness, enforceability, collectibility, interest rate, repayment schedule, or accrual status of the Assigned Loans and the Assigned Commitments, the legality, validity, genuineness, or enforceability of the Loan Agreement, the Notes, or any other Loan Document referred to in, or delivered pursuant to, the Loan Agreement or the financial condition or creditworthiness of the Borrowers. The Assignor has not acted and will not be acting as either the representative, agent or trustee of the Assignee with respect to matters arising out of or relating to the Loan Agreement or this Agreement. From and after the Effective Date, the Assignor shall have no rights or obligations with respect to the Assigned Loans and the Assigned Commitments.

7. Method of Payment. All payments to be made by the Assignor or the Assignee party hereunder shall be in funds available at the place of payment on the same day and shall be made by wire transfer to the account designated by the party to receive payment.

8. Integration. This Agreement shall supersede any prior agreement or understanding between the parties (other than the Loan Agreement or other Loan Documents) as to the subject matter hereof.

9. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument, and shall be binding upon the parties, their successors and assigns.

10. Governing Law. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of New York applicable to contracts made and to be performed in New York.
