or the Maximum Borrowing Amount as of the date of such Loan; (x) the fact that no Default or Event of Default shall then exist or immediately after the Loan would exist; (y) the fact that all of the Loan Documents shall still be in full force and effect; and (z) the fact that the representations and warranties contained herein and in the Loan Documents shall be true and correct in all material respects as if made on and as of the date of such borrowing, except to the extent that any thereof expressly relate to an earlier date.

(ii) Subject to the satisfaction of the conditions set forth in Sections 2.2(a)(i) and 6, Loans shall be effected at the principal banking office of the Agent in Cleveland, Ohio, and shall be made at such times as the Borrower may request by notice to the Agent no later than 11:00 A.M. Cleveland, Ohio time (A) three Business Days prior to the date of a requested LIBOR Loan and (B) one Business Day prior to the date of a requested Base Rate Loan. Such notices shall be in writing, or by telephonic communication confirmed by telecopy or other facsimile transmission on the same day as the telephone request, and shall specify the proposed date and the amount of the requested Loan, whether it is to bear interest initially at an interest rate based on the Base Rate or the LIBOR Rate, and the Interest Period thereof, if applicable. The Agent shall be entitled to rely on any such telephonic communication regardless of whether it is subsequently confirmed in writing.

(iii) Upon receipt of each borrowing notice for a Loan, the Agent shall promptly notify each Lender of the type, Interest Period, if applicable, amount and date of the proposed borrowing or conversion. Not later than 11:00 A.M. Cleveland time, on the date of a proposed borrowing of a Loan, each Lender shall provide the Agent at its address specified in Section 13.4 hereof with immediately available funds covering such Lender’s Ratable Share of the borrowing, and the Agent shall pay over such immediately available funds to the Borrower.

(b) Conversion/Continuation of the Loans. At the Borrower’s election pursuant to notice given to the Agent not later than 11:00 A.M. Cleveland, Ohio time three Business Days prior to such conversion or continuation, any Base Rate Loan may be converted to, or any LIBOR Loan may be continued as, as the case may be, a LIBOR Loan as requested by the Borrower; provided, however, that each conversion and continuation shall be in an amount which is a minimum of $5,000,000, and integral multiples of $1,000,000 in excess thereof; and provided, further, that no Loan may be continued as or converted to a LIBOR Loan at any time that a Default or Event of Default exists. If the Borrower has not timely delivered to the Agent such notice with respect to any terminating Interest Period, the affected LIBOR Loan shall convert to a Base Rate Loan at the end of such Interest Period.

(c) Number of Interest Rate Options. In no event shall the Borrower have more than five LIBOR Loans outstanding at any time.

2.3 The Notes. All Loans shall be evidenced by separate promissory notes payable to the Lenders substantially in the form attached hereto as Exhibit A to be duly executed and delivered by the Borrower at or prior to the Closing Date in the aggregate principal amount of the Commitment (which notes may be referred to herein as the “Notes”). The Lenders may, and are hereby authorized by the Borrower to, set forth on the grids attached to the Notes, or in other comparable records maintained by them, the amount of each Loan, all payments and

- 21 -

prepayments of principal and interest received, the current outstanding principal balance, and other appropriate information. The aggregate unpaid amount of any Loan set forth in any records maintained by a Lender with respect to a Note shall be presumptive evidence of the principal amount owing and unpaid on such Note. Failure of a Lender to record the principal amount of any Loan on the grid(s) attached to a Note shall not limit or otherwise affect the obligation of the Borrower hereunder or under such Note to repay the principal amount of such Loan and all interest accruing thereon.

2.4 Fees.

(a) Commitment Fees. The Borrower shall pay to the Agent for the benefit of the Lenders a non-refundable commitment fee of 0.125% per annum (based on a year having 360 days and actual days elapsed) on the excess of the aggregate daily average amount of the Commitment for each month over the sum of the daily average amount of the Loans outstanding for such month. Such commitment fee shall (i) commence to accrue as of the date hereof and continue to and including the Termination Date, (ii) be in addition to any other fee required by the terms and conditions of this Agreement, (iii) be payable monthly in arrears on the last Business Day of each month and on the date the Commitment is terminated, and (iv) be shared by the Lenders in accordance with their Ratable Shares.

(b) Other Fees. The Borrower shall pay to the Agent such other fees as are set forth in the Fee Letter or in any separate agreements among the Borrower, the Agent and the Lenders.

2.5 Prepayment.

(a) Voluntary Prepayments. By notice to the Agent (which shall be in writing or by telephonic communication confirmed by telecopy or other facsimile transmission on the same day as such telephone notice) no later than 11:00 A.M. Cleveland, Ohio time on the Business Day prior to such prepayment (with respect to any Base Rate Loan) or on the third Business Day prior to such prepayment (with respect to any LIBOR Loan), the Borrower may, at its option, prepay the Loans in whole at any time or in part from time to time without penalty or premium (except as provided in Section 2.5(d)); provided, however, that each partial prepayment of the Loans shall be in the aggregate principal amount of not less than $1,000,000 or an integral multiple of $500,000 in excess thereof.

(b) Mandatory Prepayments.

(i) Loans in Excess of Commitment. If at any time the outstanding principal amount of the Loans exceeds the Commitment, the Borrower shall immediately prepay the Loans, without penalty or premium (except as provided in Section 2.5(d)), in an amount necessary to cause the outstanding principal amount of the Loans not to exceed the Commitment. All accrued interest on the amount prepaid shall be paid with the prepayment.

(ii) Issuance of Additional Tower Notes. If the Tower Notes Issuers, or any of them, issue any Additional Tower Notes (other than Additional Tower Notes issued in substitution or exchange for other outstanding Tower Notes), whether pursuant to

- 22 -

Section 2.12 of the Tower Notes Indenture or otherwise, the Borrower shall make a mandatory prepayment of the Loans, as soon as such proceeds become available to the Issuer Entity, but in any event no later than the next Payment Date (as that term is defined in the Tower Notes Indenture) in respect of the Collection Period (as that term is defined in the Tower Notes Indenture) in which such Additional Tower Notes are issued, in an amount equal to the least of (A) 100% of the aggregate face amount of such Additional Tower Notes, net of any expenses reasonably incurred by the Issuers in connection with such issuance, (B) if such proceeds are deposited into the Collection Account, the amount available to be distributed to or at the direction of the Issuer Entity pursuant to clause Twentieth of Section 5.01(a) of the Tower Notes Indenture on such next Payment Date, (C) the amount of all outstanding Obligations or (D) that amount that, when applied to reduce the outstanding principal amount of the Loans, after giving effect to such prepayment and the issuance of such Additional Tower Notes, would result in the outstanding principal amount of the Loans being equal to the Maximum Borrowing Amount as of the date of such prepayment.

(iii) Sale of Towers. If any Consolidated Party sells or otherwise disposes of any towers the cash flow of which has been included in any calculation of the Maximum Borrowing Amount, the Borrower shall immediately notify the Agent of such sale or disposition and deliver to the Agent a certificate in form and substance satisfactory to the Agent showing in reasonable detail the calculation of the Maximum Borrowing Amount after giving effect to such sale or other disposition and not including in such calculation any cash flow attributable to such towers. If the outstanding principal amount of the Loans exceeds the Maximum Borrowing Amount as so recalculated, the Borrower shall, within two Business Days of such sale or other disposition, make a mandatory prepayment of the Loans in an amount equal to that amount that, when applied to reduce the outstanding principal amount of the Loans, would result in the outstanding principal amount of the Loans being equal to the Maximum Borrowing Amount as of the date of such prepayment, or such higher amount as may be required pursuant to Section 8.1(c).

(iv) Sale of Crown Australia. If all or substantially all of the Equity Interests or assets of Crown Australia or any of the Subsidiaries of Crown Australia are sold, transferred or otherwise disposed of, then the Borrower shall make a mandatory prepayment of the Loans in an amount equal to the least of (A) $100,000,000, (B) the aggregate amount of Loan proceeds that have been used, or designated for use pursuant to any Borrowing Requests, to make Capital Distributions by Crown International during the period from the Closing Date to the date of such sale, transfer or other disposition and (C) the amount of all outstanding Obligations. Such mandatory prepayment shall be made within two Business Days of the consummation of such sale, transfer or other disposition.

(c) Application of Prepayments. All prepayments made pursuant to this Section 2.5 shall be applied as follows: first, to any LIBOR Prepayment Premium then due, then to accrued interest and then to the outstanding principal of the Loans. For purposes of the calculation of interest and the determination of whether any LIBOR Prepayment Premium is due in connection with any such prepayment of LIBOR Loans, such principal prepayments shall be applied first to the Base Rate Loans and then to the LIBOR Loans with the shortest remaining Interest Periods. No prepayment shall reduce the amount of the Commitment, provided that the Commitment shall be immediately and automatically reduced by the amount of any prepayment made, or required to be made, pursuant to Section 2.5(b)(iv).

- 23 -

(d) LIBOR Prepayment Premium. The Borrower shall pay to the Agent, for the benefit of the Lenders, the applicable LIBOR Prepayment Premium upon any prepayment or conversion (whether voluntary or involuntary) of any LIBOR Loan not made on the last day of the applicable Interest Period.

2.6 Reserves or Deposit Requirements, Etc. If at any time any Regulatory Change (including without limitation, any change in Regulation D of the Board of Governors of the Federal Reserve System) shall impose upon, modify, require, make or deem applicable to the Agent or any Lender (or its holding company) any reserve, special deposit requirement (other than reserves included in the LIBOR Reserve Percentage, the effect of which is reflected in the interest rate of any LIBOR Loan), insurance assessment or similar requirement against assets held by any Lender or deposits in any Lender or for the amount of any loans by any Lender, and the result of the foregoing is to increase the cost (whether by incurring a cost or adding to a cost) to such Lender of taking or maintaining hereunder any LIBOR Loan or to reduce the amount of principal, interest or fees received by such Lender with respect to any such Loan, then such Lender shall notify the Borrower and the Agent of such occurrence. Thereafter, within ten days after written demand by such Lender, the Borrower shall pay to such Lender additional amounts sufficient to compensate and indemnify such Lender for such increased cost or reduced amount. A statement as to the increased cost or reduced amount as a result of any event mentioned in this Section shall be submitted by such Lender to the Agent and to the Borrower and shall, in the absence of manifest error, be conclusive and binding as to the amount thereof. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

2.7 Tax Law, Increased Costs, Etc. In the event that any Lender shall, with respect to this Agreement or any transaction under this Agreement, be subjected to any tax, levy, impost, charge, fee, duty, deduction or withholding of any kind whatsoever, or any change in the basis of taxation of any amounts payable to such Lender under this Agreement or with respect to any transaction under this Agreement, and if any such measure or any other similar measure shall result in an increase in the costs to such Lender of making or maintaining any LIBOR Loan or in a reduction in the amount of principal, interest or other payments ultimately receivable by such Lender in respect of such Loan (other than, for purposes of this Section 2.7, any such increased costs resulting from (a) Indemnified Taxes or Other Taxes (as to which Section 2.13 shall govern), and (b) changes in the basis of taxation upon the net income of such Lender), then such Lender shall notify the Agent and the Borrower stating the reasons therefor. The Borrower shall thereafter pay to such Lender within ten days after written demand such additional amounts as will compensate such Lender for such increased cost or reduced amount. A statement as to any such increased cost or reduced amount shall be submitted by such Lender to the Agent and the Borrower which statement shall, in the absence of manifest error, be conclusive and binding as to the amount thereof. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

2.8 Eurodollar Deposits Unavailable or Interest Rate Unascertainable. If any Lender determines that dollar deposits of the relevant amount for the relevant Interest Period are not available to it in the applicable Eurodollar market or if the Agent determines that, by reason

- 24 -

of circumstances affecting such market, adequate and reasonable means do not exist for ascertaining the LIBOR Rate applicable to such Interest Period, or if any Lender determines that the LIBOR Rate does not adequately reflect the cost to such Lender of making such Loan, as the case may be, the Agent or such Lender shall promptly give notice of such determination to the Agent and to the Borrower, and any request for a new LIBOR Loan or notice of conversion of an existing Loan to a LIBOR Loan given thereafter or previously given by the Borrower and not yet made or converted shall be deemed a notice to make a Base Rate Loan.

2.9 Changes in Law Rendering LIBOR Loans Unlawful. If at any time any Regulatory Change shall make it unlawful for any Lender to fund any LIBOR Loan which it has committed to make hereunder with moneys obtained in the applicable Eurodollar market, such Lender shall notify the Agent and the Borrower, and the obligation of the Lenders to fund such Loan shall, upon the happening of such event, forthwith be suspended until the Agent shall notify the Borrower that such illegality has ceased. If any such change makes it unlawful for any Lender to continue in effect the funding in the applicable Eurodollar market of any LIBOR Loan previously made by it hereunder, such Lender shall, upon the happening of such event, notify the Agent and the Borrower thereof in writing stating the reasons therefor, and the Borrower shall, on the earlier of (a) the last day of the then current Interest Period or (b) if required by such Regulatory Change on such date as shall be specified in such notice, either convert all such Loans to Base Rate Loans or prepay all such Loans in full.

2.10 Funding. Any Lender may, but shall not be required to, make LIBOR Loans hereunder with funds obtained outside the United States.

2.11 Indemnity. Without prejudice to any other provisions of Sections 2.6 through 2.10 or to the obligation of the Borrower to pay the LIBOR Prepayment Premium pursuant to Section 2.5(d), the Borrower hereby agrees to indemnify the Agent and each Lender against any loss or expense which the Agent or any Lender may sustain or incur as a consequence of the Borrower’s failure to borrow any LIBOR Loan requested pursuant to this Agreement, or the Borrower’s failure to continue any LIBOR Loan or convert any Base Rate Loan to a LIBOR Loan, in either case after notice of such continuation or conversion shall have been given to the Agent pursuant to Section 2.2(b), or any default by the Borrower in payment when due of any amount due hereunder in respect of any LIBOR Loan or any prepayment or conversion by the Borrower of a LIBOR Loan prior to the end of its Interest Period, whether voluntarily or as required pursuant to the terms hereof, including, but not limited to, any premium or penalty incurred by such Lender in respect of funds borrowed by it for the purpose of making or maintaining such Loan, as determined by such Lender; provided, however, that such indemnification shall be net of any LIBOR Prepayment Premium received by such Lender in respect of any such action or inaction of the Borrower. A statement as to any such loss or expense shall be submitted by such Lender to the Agent and the Borrower for payment under the aforesaid indemnification, which statement shall, in the absence of manifest error, be conclusive and binding as to the amount thereof.

2.12 Capital Adequacy. If any Lender shall determine that any Regulatory Change regarding capital adequacy or compliance by such Lender (or its lending office) with any request or directive regarding capital adequacy (whether or not having the force of law) of any Governmental Authority, central bank or comparable agency has or would have the effect of

- 25 -

reducing the rate of return on such Lender’s capital (or on the capital of such Lender’s holding company) as a consequence of its obligations hereunder to a level below that which such Lender (or its holding company) could have achieved but for such Regulatory Change or compliance (taking into consideration such Lender’s policies or the policies of its holding company with respect to capital adequacy) by an amount which such Lender deems to be material, then from time to time, within ten days after demand by such Lender, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender (or its holding company) for such reduction. A certificate of such Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. Failure on the part of any Lender to demand compensation for any reduction in return on capital with respect to any period shall not constitute a waiver of such Lender’s rights to demand compensation for any reduction in return on capital in such period or in any other period. The protection of this Section shall be available to each Lender regardless of any possible contention of the invalidity or inapplicability of the law, regulation or other condition which shall have been imposed.

2.13 Taxes. Without duplication of any other Section of this Agreement, including, without limitation, Section 2.7:

(a) Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes, provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Agent or Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law, provided, that the Borrower hereby indemnifies the Agent and the Lenders and holds them harmless from and against any and all liabilities, fees or additional expenses with respect to or resulting from any delay in paying, or omission to pay, such amounts, and (iv) within thirty days after the payment by the Borrower of any such Indemnified Taxes or Other Taxes, the Borrower shall furnish the Agent with the original or a certified copy of the receipt, if any, evidencing payment thereof, or such other information as the Agent may reasonably require to establish to its satisfaction that full and timely payment of such Indemnified Taxes and Other Taxes has been made.

(b) The Borrower agrees to pay any Other Taxes to the relevant Governmental Authority in accordance with applicable Law.

(c) The Borrower agrees to indemnify each Lender and Agent for the full amount of Indemnified Taxes and Other Taxes (including, without limitation, the full amount of taxes of any kind imposed or asserted by any jurisdiction on amounts payable under this Section 2.13) imposed on or paid by such Lender or Agent, as the case may be, and any liability (including penalties, additions to tax, interest and expenses) arising therefrom and with respect thereto. Each Lender shall notify the Borrower and the Agent of any payment of

- 26 -

Indemnified Taxes or Other Taxes required or requested of it. Upon notice from such Lender that Indemnified Taxes or Other Taxes or any liability relating thereto (including penalties, additions to tax, and interest and expenses) have been paid, the Borrower shall pay or reimburse such Lender therefor within ten days of such notice. Such Lender shall include with any such notice a statement setting forth in reasonable detail the basis and calculation of any such payment or reimbursement to be made to it hereunder, which statement shall, in the absence of manifest error, be conclusive and binding as to the amount thereof.

(d) On or prior to the date of execution and delivery of this Agreement in the case of each Lender that is listed on the signature pages of this Agreement, and on or prior to the date of assignment in the case of each Lender that is an assignee pursuant to Section 13.7, and from time to time thereafter as reasonably requested in writing by the Borrower (but only so long thereafter as such Lender remains lawfully able to do so):

(i) Each Lender that is a “United States person” that is not a “domestic” corporation (as such term is defined in Section 7701(a)(30) of the Code) shall provide each of the Borrower and Agent with an original Internal Revenue Service Form W-9, or any successor or other form prescribed by the Internal Revenue Service, properly completed and duly executed; and

(ii) Each Lender that is not a “United States person” (as such term is defined in Section 7701(a)(30) of the Code) shall provide each of the Borrower and Agent with either:

(1) An original Internal Revenue Service Form W-8BEN, W-8IMY or W-8ECI, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, properly completed and duly executed, certifying that such Lender is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or under the Notes; or

(2) A certificate that it is not (I) a “bank” (as defined in Section 881(c)(3)(A) of the Code), (II) a ten-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrower, or (III) a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Code); and an original Internal Revenue Service Form W-8BEN or Form W-8IMY, as appropriate, or any successor or other form prescribed by the Internal Revenue Service, properly completed and duly executed, certifying that such Lender meets the requirements of Section 871(h)(2)(B)(ii) and Section 871(h)(5) of the Code and the regulations promulgated thereunder.

(e) For any period with respect to which a Lender has failed to provide the Borrower with the appropriate form, certificate or other document described in subsection (d) of this Section 2.13 (other than if such failure is due to a Regulatory Change occurring after the date on which a form, certificate or other document originally was required to be provided or if such form, certificate or other document otherwise is not required under subsection (d) of this Section 2.13), such Lender shall not be entitled to any increase in the amounts payable or any indemnification under subsection (a) or (c), respectively, of this Section 2.13 with respect to Indemnified Taxes imposed by the United States by reason of such failure; provided, however, that should a Lender become subject to Indemnified Taxes because of its failure to deliver a form, certificate or other document required hereunder, the Borrower shall take such steps as such Lender shall reasonably request to assist such Lender in recovering such Indemnified Taxes.

- 27 -

(f) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in Section 2.7 and this Section 2.13 shall survive the termination of this Agreement and the payment in full of principal, interest and all other amounts payable hereunder and under the Notes.

(g) Each Lender agrees that, in the event of a payment of an increased amount by the Borrower with respect to such Lender pursuant to subsection (a) or (b) of this Section 2.13 or a demand by such Lender for indemnification from the Borrower pursuant to subsection (c) of this Section 2.13, it will, if requested by the Borrower, use commercially reasonable efforts (consistent with overall policy considerations of such Lender and legal and regulatory restrictions) to designate a different applicable lending office if the making of such designation will avoid the need for, or reduce the amount of, such increased amount paid or such indemnification; provided, however, that the making of such designation will not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender, its Affiliates or Subsidiaries.

(h) Nothing contained in this Section 2.13 shall require any Lender or the Agent to make available any of its tax returns or any other information that it deems to be confidential or proprietary. Nothing herein contained shall interfere with the rights of each Lender to arrange its tax affairs in whatever manner it thinks fit; and, in particular, each Lender shall be under no obligation to claim credit, relief, remission or repayment from or against its profits or similar tax liability in respect of the amount of such deduction or withholding in priority to any other claims, reliefs, credits or deductions available to it or to disclose any information relating to its tax affairs.

SECTION 3. INTEREST; PAYMENTS.

3.1 Interest.

(a) Subject to Section 3.1(c), prior to maturity, LIBOR Loans shall bear interest at the LIBOR Rate plus the Applicable Margin and Base Rate Loans shall bear interest at the Base Rate.

(b) The Applicable Margin shall be determined by the Agent quarterly, based on the financial statements and the Compliance Certificate delivered to the Lenders pursuant to Sections 7.5(c) and (d). Any change in the interest rate on the Loans due to a change in the Applicable Margin shall be effective on the fifth Business Day after delivery of such financial statements and Compliance Certificate; provided, however, that if any such quarterly financial statements and Compliance Certificate indicate an increase in the Applicable Margin and such financial statements and certificate are not provided within the time period required in Section 7.5(c) and (d), the increase in the interest rate due to such increase in the Applicable Margin shall be effective retroactively as of the fifth Business Day after the date on which such financial statements and certificate were due. The Borrower shall deliver to the Lenders with each set of quarterly financial statements that indicate a change in the Applicable Margin a notice with respect to such change, which notice shall set forth the calculation of, and the supporting evidence for, such change.

- 28 -

(c) Upon the occurrence of any Event of Default, the entire outstanding principal amount of each Loan and (to the extent permitted by law) unpaid interest thereon and all other amounts due hereunder shall bear interest, from the date of occurrence of such Event of Default until the earlier of the date such Loan is paid in full and the date on which such Event of Default is cured or waived in writing, at the Default Interest Rate which shall be payable upon demand. Nothing in this Section 3.1(c) shall affect the rights of the Agent or the Lenders to exercise any rights or remedies hereunder or under the Loan Documents or applicable law arising upon the occurrence and continuance of an Event of Default.

(d) Interest shall be computed on a Three Hundred Sixty day year basis calculated for the actual number of days elapsed. Interest accrued on each Loan shall be paid monthly in arrears on the last Business Day of each month after the date hereof until such Loan is paid in full and on the date such Loan is paid in full, and, in addition, interest accrued on each LIBOR Loan shall be paid on the last day of the Interest Period thereof.

3.2 Manner of Payments.

(a) Prior to the last Business Day of each month and the end of each Interest Period, the Agent shall render a statement to the Borrower of all amounts due to the Agent and the Lenders for principal, interest and fees hereunder. All amounts listed on each such statement shall be due and payable on the last Business Day of such month or, as the case may be, the last day of such Interest Period, in respect of which such statement was sent. As to all other Obligations which become due and payable other than on a fixed date by their terms, the Agent shall advise the Borrower by a written statement that they are due and payable, and the Borrower shall pay the same within ten days of receipt of such statement. If any amounts are not paid by the Borrower when due and payable, such amounts shall bear interest at the Default Interest Rate, and the Lenders may then charge any account of the Borrower for such Obligation in the amount due to the Lenders. Any failure by the Agent to render any such statement or give any such advice shall in no way relieve the Borrower of any liability for or obligation to pay any amount due and payable hereunder.

(b) Whenever any payment to be made hereunder, including without limitation any payment to be made on a Note, shall be stated to be due on a day that is not a Business Day, such payment may be made on the next succeeding Business Day, and such extension of time shall in each case be included in the computation of the interest payable on such Note.

(c) Unless otherwise provided in this Agreement, all payments or prepayments made or due hereunder or under the Notes shall be made in immediately available funds by federal funds wire transfer, and without setoff, deduction or counterclaim, to the Agent prior to 11:00 A.M., Cleveland time, on the date when due, at its offices at 000 Xxxxxx Xxxxxx, Xxxxxxxxx, Xxxx 00000, or at such other place as may be designated by the Agent. Funds received after 11:00 A.M., Cleveland time, shall be deemed to have been received on the next Business Day. To the extent any such payment is made for the ratable benefit of the Lenders, the Agent shall promptly distribute such payment to the Lenders in accordance with their respective Ratable Shares.

- 29 -

SECTION 4. CLOSING.

The closing of the funding of the initial Loans hereunder shall take place at the offices of the Agent at 000 Xxxxxx Xxxxxx, Xxxxxxxxx, Xxxx 00000 on or about August 1, 2005, or such other date and place as to which the parties may agree (the “Closing” and the “Closing Date”). Subject to the terms and conditions hereof, upon the fulfillment or waiver in writing of all the conditions precedent set out in Section 6 below, and the delivery to the Agent of the Notes, the Lenders shall make such Loans as the Borrower may request.

SECTION 5. REPRESENTATIONS AND WARRANTIES OF THE BORROWER.

To induce the Lenders to enter into this Agreement and to make the Loans, the Borrower and the Guarantors, jointly and severally, represent and warrant as follows:

5.1 Organization and Powers. Each Consolidated Party is a corporation or limited liability company, duly organized, validly existing and in good standing under the laws of the state of its incorporation or formation. Each Consolidated Party is duly qualified or registered to conduct business and in good standing under the laws of each jurisdiction in which the character of its business or the ownership of its assets makes such qualification or registration necessary, except where failure to so qualify or register could not reasonably be expected to have a Material Adverse Effect. Each Consolidated Party has all requisite power and authority to own and operate its properties, to carry on its business as now conducted and proposed to be conducted and to enter into, and perform its obligations under, each of the following to which it is a party: this Agreement, the Loan Documents, the Acquisition Agreement and each other document in connection with the transactions contemplated thereby. The Borrower has all requisite power and authority to incur the indebtedness contemplated hereunder and evidenced by the Notes.

5.2 Authorization. All necessary actions on the part of the Loan Parties to authorize the execution and delivery of this Agreement, the Loan Documents and the Acquisition Agreement, and the performance of the obligations of the Loan Parties herein and therein, have been taken. This Agreement, each Loan Document and the Acquisition Agreement have been duly authorized and executed and are valid and legally binding upon each Loan Party to the extent it is a party thereto, and enforceable in accordance with their respective terms, except to the extent that the enforceability thereof may be limited by bankruptcy, insolvency or like laws affecting creditors rights generally and the availability of equitable remedies.

5.3 Financial Statements. The Borrower has provided to the Lenders complete and correct copies of (a) the audited consolidated financial statements for Crown International and its Subsidiaries for the fiscal years ended December 31, 2004, and December 31, 2003, (b) the unaudited pro forma condensed consolidated balance sheet of Crown Castle Towers LLC and the Asset Entities as of December 31, 2004, and the unaudited pro forma condensed consolidated statement of operations for each of the years in the two-year period ended December 31, 2004, and (c) the unaudited consolidating balance sheets and income

The Financial Statements disclose all material contingent liabilities and present fairly the financial condition of Crown International and its Subsidiaries, Crown Castle Towers LLC and the Asset Entities, and the Borrower and its Subsidiaries, as of the dates and for the periods indicated and have been prepared consistent with GAAP, subject in the case of statements for interim periods to the absence of footnotes and to normal year-end adjustments.

5.4 Projections. The Borrower has provided to the Lenders complete and correct copies of the Consolidated Parties’ projections for the calendar years 2005 and 2006. Such projections were prepared on an operating basis. Such projections represent the Loan Parties’ good faith estimate of projected future operations as of the date of this Agreement, have been prepared based on assumptions that the Loan Parties believe to be reasonable and assume the consummation of the transactions contemplated by the Acquisition Agreement. As of the date hereof, there are no facts which are known to any Loan Party which such Loan Party believes would cause a material adverse change in such projections.

5.5 Capitalization. Schedule 5.5 attached hereto sets forth, as of the date hereof each Subsidiary of Crown International. Except as set forth on Schedule 5.5, each Subsidiary of Crown International is wholly owned, directly or indirectly, by Crown International.

Without limiting the generality of the foregoing, each Guarantor’s liability shall extend to all amounts that constitute part of the Guarantied Obligations and would be owed by any other Loan Party to the Agent or any Lender under or in respect of this Agreement and the Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving such other Loan Party.

(e) any change, restructuring or termination of the corporate structure or existence of any Loan Party or any of its Subsidiaries or any insolvency, bankruptcy, reorganization or other similar proceeding affecting any Consolidated Party or its assets or any resulting release or discharge of any Guarantied Obligation;

(f) the existence of any claim, setoff or other right which any Guarantor may have at any time against any Loan Party, the Agent, any Lender or any other Person, whether in connection herewith or with any unrelated transaction;

- 60 -

(g) any provision of applicable Law purporting to prohibit the payment or performance by any Loan Party of the Guarantied Obligations;

(h) any failure of the Agent or any Lender to disclose to any Loan Party any information relating to the business, condition (financial or otherwise), operations, performance, properties or prospects of any other Loan Party now or hereafter known to the Agent or such Lender (each Guarantor waiving any duty on the part of the Agent and the Lenders to disclose such information);

(i) the failure of any other Person to execute or deliver this Agreement or any other guaranty or agreement or the release, subordination or reduction of liability of any Guarantor or other guarantor or surety with respect to the Guarantied Obligations; or

(j) any other circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by the Agent or any Lender that might otherwise constitute a defense available to, or a discharge of, any Loan Party or any other guarantor or surety.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guarantied Obligations is rescinded or must otherwise be returned by the Agent or any Lender or any other Person upon the insolvency, bankruptcy or reorganization of any Consolidated Party or otherwise, all as though such payment had not been made.

In determining compliance with any condition hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Agent may presume that such condition is satisfactory to such Lender unless the Agent shall have received notice to the contrary from such Lender prior to the making of such Loan. The Agent may consult with legal counsel (who may be counsel for the Loan Parties), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

12.7 Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent (which indemnification shall be shared by the Lenders ratably in proportion to their respective Ratable Shares) (a) for any amounts not reimbursed by the Loan Parties for which the Agent is entitled to reimbursement by the Loan Parties hereunder or under any Loan Document, (b) for any other expenses reasonably incurred by the Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration, amendment or enforcement hereof or of any of the Loan Documents and (c) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of this Agreement, any Loan Document or any other document related hereto or thereto or the transactions contemplated hereby or the enforcement of any of the terms hereof or thereof or of any such other documents, provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Agent.

12.8 Rights as a Lender. With respect to its Ratable Share of the Commitment, the Loans made by it and the Notes issued to it, the Agent shall have the same rights and powers hereunder as any Lender and may exercise the same as though it were not the Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent may accept deposits from, lend money to, and generally engage in any kind of banking or trust business with the Consolidated Parties as if it were not the Agent hereunder.

12.9 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any other Lender and based on the financial statements prepared by the Consolidated Parties and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such

- 65 -

documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the Loan Documents. The Agent shall not be required to keep the Lenders informed as to the performance or observance by the Loan Parties of this Agreement or any other document referred to or provided for herein or to inspect the properties or books of any Consolidated Party. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of any Consolidated Party that may come into its possession.

12.10 Successor Agent.

(a) The Agent may, without the consent of the Borrower or the other Lenders, assign its rights and obligations as Agent hereunder and under the Loan Documents to any of its wholly owned subsidiaries that has capital and retained earnings of at least $500,000,000, and upon such assignment, the former Agent shall be deemed to have retired, and such wholly owned subsidiary shall be deemed to be a successor Agent.

(b) The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders, with the consent of the Borrower, which shall not be unreasonably withheld, shall have the right to appoint a successor Agent; provided, however, that the consent of the Borrower shall not be required if at the time of such resignation an Event of Default exists. If no successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty days after the notice of resignation, then the retiring Agent may appoint a successor Agent. Such successor Agent shall be a financial institution having capital and retained earnings of at least $500,000,000.

(c) Upon the acceptance of any appointment as the Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the assigning or retiring Agent, and the assigning or retiring Agent shall be discharged from its duties and obligations hereunder. After any assigning or retiring Agent’s resignation hereunder as the Agent, the provisions of this Section 12 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 Agent hereunder.

12.11 Ratable Sharing. All principal and interest payments on Loans and commitment fees received by the Agent shall be remitted to the Lenders in accordance with their Ratable Shares. Any amounts received by the Agent or any other Lender upon the sale of any Collateral or upon the exercise of any remedies hereunder or under any of the Loan Documents or upon the exercise of any right of setoff shall be applied in accordance with Section 10.6. If any Lender shall obtain any payment hereunder (whether voluntary, involuntary, through exercise of any right of set-off or otherwise) in excess of its Ratable Share, then such Lender shall immediately remit such excess to the other Lenders pro rata.

12.12 Actions by the Agent and the Lenders. The Agent shall take formal action following the occurrence of a Default or an Event of Default only upon the agreement of the

- 66 -

Required Lenders; provided, however, that if the Agent gives notice to the Lenders of a Default or an Event of Default, and the Required Lenders cannot agree (which agreement shall not be unreasonably withheld) on a mutual course of action within ten days following such notice, the Agent may (but shall not be required to) pursue such legal rights and remedies against the Loan Parties as it deems necessary and appropriate to protect the Lenders and any Collateral under the circumstances.

12.13 Collateral Matters.

(a) The Agent is authorized by each Lender, without the necessity of any notice to or further consent from any Lender, and without the obligation to take any such action, to take any action with respect to any Collateral or any Loan Document that the Agent reasonably believes may from time to time be necessary to perfect and maintain perfected the Liens of the Loan Documents.

(b) The Lenders irrevocably authorize the Agent, at its option and in its discretion, to release any Lien granted to or held by the Agent upon any Collateral (i) upon termination of the Commitment and the payment in full of all Loans and all other Obligations payable under this Agreement and the Loan Documents (other than contingent Obligations that expressly survive the termination of this Agreement or the Loan Documents); (ii) constituting property of a Consolidated Party that is sold, transferred or otherwise disposed of in connection with any transaction not prohibited by this Agreement or the Loan Documents; or (iii) if approved or consented to by those of the Lenders required by Section 13.14. Upon request by the Agent, the Lenders will confirm in writing the Agent’s authority to release particular types or items of collateral pursuant to this Section.

SECTION 13. MISCELLANEOUS.

13.1 Construction. The provisions of this Agreement shall be in addition to those of the Loan Documents and to those of any other guaranty, security agreement, note or other evidence of the liability relating to the Loan Parties held by the Lenders, all of which shall be construed as complementary to each other. Nothing contained herein shall prevent the Agent or the Lenders from enforcing any or all of such instruments in accordance with their respective terms. Each right, power or privilege specified or referred to in this Agreement or in any Loan Document is in addition to any other rights, powers or privileges that the Agent or the Lenders may otherwise have or acquire by operation of law, by other contract or otherwise. No course of dealing in respect of, nor any omission or delay in the exercise of, any right, power or privilege by the Agent or the Lenders shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any further or other exercise thereof or of any other right, power or privilege, as each right, power or privilege may be exercised independently or concurrently with others and as often and in such order as the Agent or the Lenders may deem expedient. Notwithstanding any other provision of this Agreement, the Borrower shall not be required to pay any amount of interest pursuant hereto or pursuant to the Notes that is in excess of the maximum amount permitted by law.

13.2 Further Assurance. From time to time, the Borrower and each Guarantor shall, and shall cause their Subsidiaries to, execute and deliver to the Agent and the Lenders such

- 67 -

additional documents and take such additional actions as the Agent may reasonably require to carry out the purposes of this Agreement or any of the Loan Documents, or to preserve and protect the rights of the Agent and the Lenders hereunder or thereunder.

13.3 Expenses of the Agent and the Lenders; Indemnification.

(a) Whether or not the transactions contemplated by this Agreement are consummated, the Borrower and the Guarantors shall pay the costs and expenses, including the reasonable fees and disbursements of the Agent’s special counsel, incurred by the Agent and the Lenders in connection with (i) the negotiation, preparation, administration, amendment or enforcement of this Agreement and the Loan Documents and the closing of the transactions contemplated hereby and thereby; (ii) the perfection of the Liens granted pursuant hereto or pursuant to the Loan Documents; (iii) the making of the Loans hereunder; (iv) the negotiation, preparation or enforcement of any other document in connection with this Agreement, the Loan Documents or the Loans made hereunder; (v) any proceeding brought or formal action taken by the Agent or the Lenders to enforce any provision of this Agreement or any Loan Document, or to enforce or exercise or preserve any right, power or remedy hereunder or thereunder; or (vi) any action which may be taken or instituted by any Person against the Agent or any Lender as a result of any of the foregoing. The fees and expenses of the Agent’s special counsel through the Closing Date shall be paid on the Closing Date. If any taxes, charges or fees shall be payable, or ruled to be payable, to any state or federal authority in respect of the execution, delivery or performance of this Agreement, any Note or any other Loan Document by reason of any existing or hereinafter enacted Federal or state statute (other than any such taxes on the net income of the Lenders and any taxes, charges or fees that are included in the LIBOR Reserve Percentage), the Borrower will pay all such taxes, charges or fees, including interest and penalties thereon, if any, and will indemnify and hold harmless the Agent and the Lenders against any liability in connection therewith.

(b) The Borrower and the Guarantors hereby, jointly and severally, indemnify and hold harmless the Agent and each Lender and their respective directors, officers, employees, agents, counsel, subsidiaries and affiliates (the “Indemnified Persons”) from and against any and all claims, losses, liabilities, obligations, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys fees) that may be imposed on, incurred by, or asserted against any Indemnified Person in any way relating to or arising out of this Agreement, the Loan Documents, or the Loans made pursuant hereto, or the use of the proceeds thereof, or any of the transactions contemplated hereby or thereby or the business, assets or operations of any Consolidated Party or the ownership, maintenance, operation or management of the Tower Sites; provided, however, that the Borrower and the Guarantors shall not be liable to any Indemnified Person if there is a final non-appealable judicial determination that such claims, losses, liabilities, obligations, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulted solely from the gross negligence or willful misconduct of such Indemnified Person.

13.4 Notices. Except as otherwise expressly provided herein, all notices, demands and requests required or permitted to be given under the provisions of this Agreement shall be in writing and shall be deemed to have been duly delivered and received (a) on the date of personal delivery, (b) on the date of receipt (as shown on the return receipt) if mailed by

13.5 Waiver and Release by the Borrower. Neither the Agent, nor any Lender, nor any Affiliate, officer, director, employee, attorney or agent of the Agent or any Lender shall have any liability with respect to, and the Borrower and the Guarantors hereby waive, release

- 69 -

and agree not to xxx any of them upon, any claim for any special, indirect, incidental or consequential damages suffered or incurred by any Consolidated Party in connection with, arising out of, or in any way related to, this Agreement or any of the Loan Documents, or any of the transactions contemplated by this Agreement or any of the Loan Documents, and the Borrower and the Guarantors hereby release the Agent and each Lender from, and hereby waive, all claims for loss or damage caused by any act or omission on the part of the Agent or any Lender or their respective officers, attorneys, agents and employees, except any such claims determined pursuant a final non-appealable judicial determination to have resulted solely from the gross negligence or willful misconduct of the Agent or such Lender.

13.6 Right of Set Off. Upon the occurrence and during the continuance of any Event of Default, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or an Affiliate of such Lender to or for the credit or the account of the Borrower or any Guarantor against any and all of the obligations of the Borrower and the Guarantors now or hereafter existing hereunder or under any Loan Document, irrespective of whether or not such Lender or its Affiliate shall have made any demand hereunder or under any Loan Document and although such obligations may be unmatured. The rights of the Lenders under this Section are in addition to other rights and remedies (including without limitation, other rights of set-off) which the Lenders may have. The Borrower and the Guarantors agree, to the fullest extent they may effectively do so under applicable law, that any other holder of a participation in any Note may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower or any of the Guarantors in the amount of such participation.

13.7 Successors and Assigns; Participations.

(a) Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the successors and assigns of such party; provided, however, that neither the Borrower nor any of the Guarantors shall assign or transfer any of its rights or obligations hereunder or under any Note without the prior written consent of all of the Lenders and the Agent.

(b) Each Lender may assign all or any part of any of its Loans, its Notes, and its share of the Commitment with the consent of the Borrower and the Agent, which consent shall not be unreasonably withheld; provided that (i) no such consent by the Borrower shall be required (A) for any such assignment by any Lender to an Affiliate of such Lender or to another Lender or an Affiliate of another Lender, or (B) if, at the time of such assignment, an Event of Default has occurred and is continuing; (ii) any such partial assignment shall be in an amount at least equal to $5,000,000; and (iii) each such assignment shall be made by a Lender in such manner that the same portion of its Loans, its Notes and its share of the Commitment is assigned to the assignee. Upon execution and delivery by the assignor and the assignee to the Borrower and the Agent of an Assignment and Amendment Agreement, in the form attached hereto as Exhibit E, pursuant to which such assignee agrees to become a “Lender” hereunder (if not already a Lender) having the share of the Commitment and Loans specified in such instrument, and upon consent thereto by the Agent and the Borrower (to the extent required), the

- 70 -

assignee shall have, to the extent of such assignment (unless otherwise provided in such assignment with the consent of the Agent), the obligations, rights and benefits of a Lender hereunder holding the share of the Commitment and Loans (or portions thereof) assigned to it (in addition to the share of the Commitment and Loans, if any, theretofore held by such assignee) and the assigning Lender shall, to the extent of such assignment, be released from the share of the Commitment and the obligations hereunder so assigned.

(c) Upon its receipt of an Assignment and Amendment Agreement pursuant to Section 13.7(b) duly executed by an assigning Lender and the assignee, together with any Note subject to such assignment and a processing and recordation fee of $3,500, the Agent shall, if such assignment has been completed, accept such assignment. Within five business days after receipt of such notice, the Borrower, at the Borrower’s own expense, shall execute and deliver to the Agent in exchange for each surrendered Note a new Note to the order of the assignee in an amount equal to the share of the Commitment and of the Loans assumed by the assignee and, if the assigning Lender has retained a portion of the Commitment and the Loans hereunder, a new Note to the order of the assigning Lender in an amount equal to the share of the Commitment and the Loans retained by it hereunder. Such new Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Notes, shall be dated the effective date of such assignment and shall otherwise be in substantially the form of Exhibit A hereto. Cancelled Notes shall be returned to the Borrower. Schedule 1.1 shall be amended by each Assignment and Amendment Agreement to reflect the revised Ratable Shares of the Lenders.

(d) A Lender may sell or agree to sell to one or more other Persons (each, a “Participant”) a participation in all or any part of any Loans held by it, or in its share of the Commitment. Except as otherwise provided in the last sentence of this Section 13.7(d), no Participant shall have any rights or benefits under this Agreement or any Note or any other Loan Documents (the Participant’s rights against such Lender in respect of such participation to be those set forth in the agreements executed by such Lender in favor of the Participant). All amounts payable by the Borrower to any Lender under Section 2 hereof in respect of Loans held by it, and its share of the Commitment, shall be determined as if such Lender had not sold or agreed to sell any participations in such Loans and share of the Commitment, and as if such Lender were funding each of such Loans and its share of the Commitment in the same way that it is funding the portion of such Loans and its share of the Commitment in which no participations have been sold. In no event shall a Lender that sells a participation agree with the Participant to take or refrain from taking any action hereunder or under any Loan Document except that such Lender may agree with the Participant that it will not, without the consent of the Participant, agree to any modification, supplement or waiver hereof or of any of the Loan Documents to the extent that the same, under Section 13.14 hereof, requires the consent of each Lender. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.6 through 2.13 and Section 13.6 with respect to its participating interest.

(e) In addition to the assignments and participations permitted under the foregoing provisions of this Section 13.7, any Lender may assign and pledge all or any portion of its Loans and its Notes to any Federal Reserve Lender 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 Lender. No such assignment shall release the assigning Lender from its obligations hereunder.

- 71 -

(f) A Lender may, subject to Section 13.19, furnish any information concerning the Consolidated Parties in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants).

(g) Anything in this Section 13.7 to the contrary notwithstanding, no Lender may assign or participate any interest in any Loan held by it hereunder to the Borrower or any of its Affiliates without the prior written consent of each Lender.

(h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Agent and the Borrower (an “SPC”) the option to provide all or any part of any Loan that such Granting Lender would otherwise be obligated to make pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. Each party hereto hereby agrees that (i) neither the grant to any SPC nor the exercise by any SPC of such option shall increase the costs or expenses or otherwise increase or change the obligations of the Loan Parties under this Agreement, (ii) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would be liable, and (iii) the Granting Lender shall for all purposes, including the approval of any amendment, waiver or other modification of any provision of this Agreement or any Loan Document, remain the lender of record hereunder. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such 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 debt of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the Laws of the United States or any State thereof. Notwithstanding anything to the contrary contained herein, any SPC may (i) with notice to the Borrower and the Agent, but without prior consent of the Borrower or the Agent and without the payment of any processing and recordation fee, assign all or any portion of its right to receive payment with respect to any Loan to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee or credit or liquidity enhancement to such SPC.

13.8 Applicable Law. THIS AGREEMENT AND THE LOAN DOCUMENTS, AND THE DUTIES, RIGHTS, POWERS AND REMEDIES OF THE PARTIES HERETO AND THERETO, SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD TO THE CONFLICTS OF LAWS PROVISIONS THEREOF), EXCEPT TO THE EXTENT THAT ANY LOAN DOCUMENT PROVIDES THAT THE LOCAL LAW OF ANOTHER JURISDICTION GOVERNS THE GRANT,

- 72 -

PERFECTION OR ENFORCEMENT OF THE LIENS GRANTED PURSUANT TO SUCH LOAN DOCUMENT. THE PROVISIONS OF THIS SECTION HAVE BEEN FULLY DISCUSSED BY THE BORROWER, THE GUARANTORS AND THE AGENT ON BEHALF OF THE LENDERS AND SHALL BE SUBJECT TO NO EXCEPTIONS. THE BORROWER AND THE GUARANTORS HAVE MADE THIS CHOICE OF GOVERNING LAW KNOWINGLY AND WILLINGLY AND AFTER CONSULTING WITH THEIR COUNSEL. NONE OF THE AGENT, ANY LENDER, THE BORROWER NOR ANY GUARANTOR HAS AGREED WITH OR REPRESENTED TO ANY OTHER PARTY THAT THE PROVISIONS OF THIS SECTION WILL NOT BE FULLY ENFORCED IN ALL INSTANCES.

13.9 ENFORCEMENT. EACH OF THE BORROWER AND THE GUARANTORS (A) HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE STATE COURTS OF THE STATE OF NEW YORK AND TO THE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, FOR THE PURPOSE OF ANY SUIT, ACTION OR OTHER PROCEEDING ARISING OUT OF OR BASED UPON THIS AGREEMENT OR ANY LOAN DOCUMENT OR THE SUBJECT MATTER HEREOF OR THEREOF BROUGHT BY THE AGENT OR THE LENDERS OR THEIR SUCCESSORS OR ASSIGNS AND (B) HEREBY WAIVES, AND AGREES NOT TO ASSERT, BY WAY OF MOTION, AS A DEFENSE, OR OTHERWISE, IN ANY SUCH SUIT, ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT SUBJECT PERSONALLY TO THE JURISDICTION OF THE ABOVE-NAMED COURTS, THAT ITS PROPERTY IS EXEMPT OR IMMUNE FROM ATTACHMENT OR EXECUTION, THAT THE SUIT, ACTION OR PROCEEDING IS BROUGHT IN AN INCONVENIENT FORUM, THAT THE VENUE OF THE SUIT, ACTION OR PROCEEDING IS IMPROPER OR THAT THIS AGREEMENT OR ANY LOAN DOCUMENT OR THE SUBJECT MATTER HEREOF OR THEREOF MAY NOT BE ENFORCED IN OR BY SUCH COURT, AND (C) HEREBY WAIVES AND AGREES NOT TO SEEK ANY REVIEW BY ANY COURT OF ANY OTHER JURISDICTION THAT MAY BE CALLED UPON TO GRANT AN ENFORCEMENT OF THE JUDGMENT OF ANY SUCH NEW YORK STATE OR FEDERAL COURT. EACH OF THE BORROWER AND THE GUARANTORS HEREBY CONSENTS TO SERVICE OF PROCESS BY REGISTERED MAIL AT THE ADDRESS TO WHICH NOTICES ARE TO BE GIVEN. EACH OF THE BORROWER AND THE GUARANTORS AGREES THAT ITS SUBMISSION TO JURISDICTION AND ITS CONSENT TO SERVICE OF PROCESS BY MAIL IS MADE FOR THE EXPRESS BENEFIT OF THE AGENT AND THE LENDERS. FINAL JUDGMENT AGAINST THE BORROWER OR ANY GUARANTOR IN ANY SUCH ACTION, SUIT OR PROCEEDING MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT, ACTION OR PROCEEDING ON THE JUDGMENT, OR IN ANY OTHER MANNER PROVIDED BY OR PURSUANT TO THE LAWS OF SUCH OTHER JURISDICTION; PROVIDED, HOWEVER, THAT THE AGENT OR THE LENDERS MAY AT THEIR OPTION BRING SUIT, OR INSTITUTE OTHER JUDICIAL PROCEEDINGS, AGAINST THE BORROWER, ANY GUARANTOR OR ANY OF THEIR ASSETS IN ANY XXXXX XX XXXXXXX XXXXX XX XXX XXXXXX XXXXXX OR OF ANY COUNTRY OR PLACE WHERE THE BORROWER, SUCH GUARANTOR OR SUCH ASSETS, MAY BE FOUND.

13.10 JURY TRIAL WAIVER. THE BORROWER, THE GUARANTORS, THE AGENT AND THE LENDERS EACH WAIVE IRREVOCABLY, TO THE EXTENT

- 73 -

PERMITTED BY LAW, ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE, AMONG THE AGENT, THE LENDERS, THE BORROWER AND THE GUARANTORS ARISING OUT OF, IN CONNECTION WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT OR THE NOTES OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS RELATED HERETO AND THERETO.

This Agreement shall inure to the benefit of, and shall be binding upon, the respective successors and permitted assigns of the parties hereto. This Agreement, the Schedules and Exhibits hereto, which are hereby incorporated in this Agreement, and the Loan Documents constitute the entire agreement among the parties on the subject matter hereof. There are no unwritten or oral agreements among the Borrower, the Guarantors, the Agent and the Lenders, and this written Agreement, the Notes, the other Loan Documents, and the instruments and documents executed in connection herewith, represent the final agreement among the parties and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties.

13.14 Modification. Any term of this Agreement or of any Note may be amended and the observance of any term of this Agreement or of any Note may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Borrower, the Guarantors and the Required Lenders, and any amendment or waiver effected in accordance with this Section 13.14 shall be binding upon each holder of a Note at the time outstanding, each future holder of a Note, the Borrower and the Guarantors; provided, however, that no such amendment or waiver or other action shall, without the prior written consent of all of the Lenders or the holders of all of the Notes at the time outstanding, (a) extend the maturity or reduce the principal amount of, or reduce the rate or extend the time of payment of interest on, or reduce the amount or extend the time of payment of any principal installment of, any Note, (b) reduce the amount or extend the time of payment of the commitment fees, (c) change the Commitment or the Ratable Share of any Lender (other than any change in Commitment or Ratable Share resulting from the sale of a participation in or assignment of any Lender’s interest in the Commitment and Loans in accordance with Section 13.7), (d) change the percentage referred to in the definition of “Required Lenders” contained in Section 1.1, or reduce the number of Lenders required to approve any consent, waiver, amendment or modification, (e) amend this Section 13.14, (f) amend or waive compliance with Section 2.5(b), or (g) release any material portion of the Collateral or any Guarantee for the Loans, except in either case in connection with a transaction otherwise permitted pursuant to this Agreement; and provided, further, that notwithstanding the foregoing provisions of this Section 13.14, this Agreement (including Schedule 1.1) and the Notes may be amended or modified in the manner contemplated by Section 13.7 for the purpose of permitting any Lender to assign its interest, rights and obligations hereunder to another Person, if the appropriate Assignment and Amendment Agreement or counterparts thereof are executed by the Borrower (to the extent required), the Agent and the appropriate Lender assignor and assignee. In addition, no amendment, waiver or consent to the provisions of Section 12, or any other provision affecting the rights or duties of the Agent, shall be made without the written consent of the Agent.

If any one or more of the provisions contained in this Agreement or any Loan Document should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of all remaining provisions shall not in any way be affected or impaired. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction.

13.16 Section Headings. The section headings contained herein are for reference purposes only and shall not in any way affect the meaning or interpretation of this Agreement.

13.17 Termination.

(a) This Agreement shall terminate when all amounts due hereunder, under each Note and under each Loan Document shall have been indefeasibly paid in full in cash and all other Obligations hereunder or thereunder shall have been fully performed, so long as the

Lenders have no further obligation to advance sums hereunder. Notwithstanding the foregoing, this Agreement shall continue to be effective or be reinstated and relate back to such time as though this Agreement had always been in effect, as the case may be, if at any time any amount received by the Agent or any Lender in respect of the Obligations is rescinded or must otherwise be restored or returned by such Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of any Consolidated Party or any other Person or upon the appointment of any intervenor or conservator of, or trustee or similar official for, any Consolidated Party or any other Person or any substantial part of its properties, or otherwise, all as though such payments had not been made. Notwithstanding anything to the contrary contained herein or in any Loan Document, any indemnification or expense reimbursement provision contained herein or in any Loan Document shall remain in full force and effect notwithstanding the termination of this Agreement or such Loan Document.

(b) In connection with any termination of or release from the Borrower’s obligations under Section 7.12(a), the Agent shall execute and deliver to the Borrower, at the Borrower’s expense, all documents that the Borrower shall reasonably request to evidence such termination or release. Any execution and delivery of documents pursuant to this Section 13.17 shall be without recourse to or warranty by the Agent.

13.18 Interest Limitation. It is the intention of the Borrower and the Lenders to conform strictly to the respective usury laws applicable to the Lenders. Accordingly, if the transactions contemplated hereby would be usurious under applicable law as to any Lender, then, in that event, notwithstanding anything to the contrary in the Notes or this Agreement or in any other Loan Document, it is agreed as follows: (a) the aggregate of all consideration that constitutes interest under law applicable to such Lender that is contracted for, taken, reserved, charged or received under any Note payable to such Lender or this Agreement or under any other Loan Document or otherwise in connection with such Note shall under no circumstances exceed the maximum amount allowed by such law (or, if the principal amount of such Note shall have been or would thereby be paid in full, refunded to the Borrower); and (b) in the event that the maturity of any Note payable to a Lender is accelerated or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to such Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be cancelled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of such Note (or, if the principal amount of such Note shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All calculations made to compute the rate of interest that is contracted for, taken, reserved, charged or received under any Note payable to any Lender or under this Agreement or under any Loan Document or otherwise in connection with such Note for the purpose of determining whether such rate exceeds the maximum amount allowed by law applicable to such Lender shall be made, to the extent permitted by such applicable law, by amortizing, prorating, and spreading in equal parts during the period of the full stated term of the Loan or Loans evidenced by such Note all interest at any time contracted for, taken, reserved, charged or received by such Lender in connection therewith.

13.19 Confidentiality. Each of the Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed

- 76 -

(a) to its Affiliates and to its and its Affiliates’ partners, directors, officers, employees, advisors and representatives in connection with the administration of its rights and performance of its obligations hereunder (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority purporting to have authority over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable Law or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any Loan Document or any action or proceeding relating to this Agreement or any Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (ii) any pledgee referred to in Section 13.7(e) or (iii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Loan Parties and their obligations, (g) with the consent of the Borrower or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section or (y) becomes available to the Agent, any Lender or any of their respective Affiliates on a nonconfidential basis from a source other than any Consolidated Party or any of their Affiliates. For purposes of this Section, “Information” means all information received from any Consolidated Party relating to any Consolidated Party or any of their respective businesses that is clearly identified at the time of delivery as confidential, other than any such information that is available to the Agent or any Lender on a nonconfidential basis prior to disclosure by the Consolidated Parties. Any Person required to maintain the confidentiality of Information as provided in this Section 13.19 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

13.20 Marshaling. The Agent and the Lenders shall not be under any obligation to marshal any assets in favor of a Loan Party or any other Person or against or in payment of any or all of the Obligations.

13.21 USA Patriot Act Notice. Each of the Agent (for itself and not on behalf of any Lender) and each Lender hereby notifies the Loan Parties that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), it is or may be required to obtain, verify and record information that identifies the Loan Parties, which information includes the names and addresses of the Loan Parties and other information that will allow such Lender or the Agent, as applicable, to identify the Loan Parties in accordance with such Act.

13.22 Waivers. As additional consideration for the execution, delivery and performance of this Agreement by the parties hereto and the execution, delivery and performance of the Loan Documents by the parties thereto, the Borrower and the Guarantors warrant and represent that no facts, events, statuses or conditions exist or have existed which, either now or with the passage of time or giving of notice, or both, constitute or will constitute a basis for any claim or cause of action against the Agent or any Lender or any defense to (i) the payment of any indebtedness hereunder or under the Notes or the Loan Documents, or (ii) the performance of

- 77 -

any of its obligations with respect to this Agreement, the Notes or the Loan Documents, and in the event any such facts, events, statuses or conditions exist or have existed, the Borrower and the Guarantors unconditionally and irrevocably waive any and all claims and causes of action against the Agent and the Lenders and any defense to its payment and performance obligations in respect to this Agreement, the Notes and the Loan Documents.
