(b) Any Eurodollar Loan may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Borrower giving irrevocable notice to the Administrative Agent, in accordance with the applicable provisions of the term “Interest Period” set forth in Section 1.1, of the length of the next Interest Period to be applicable to such Revolving Credit Loans, provided that no Eurodollar Loan may be continued as such (i) when any Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined in its or their sole discretion not to permit such continuations or (ii) after the date that is one month prior to the final scheduled termination or maturity date of the Revolving Credit Facility; and provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso such Revolving Credit Loans shall be automatically converted to Base Rate Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof.

2.9. Minimum Amounts and Maximum Number of Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions, continuations and optional prepayments of Eurodollar Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar Tranche shall be equal to $2,500,000 or a whole multiple of $500,000 in excess thereof and (b) no more than eight Eurodollar Tranches shall be outstanding at any one time.

2.10. Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin.

(b) Each Base Rate Loan shall bear interest at a rate per annum equal to the Base Rate plus the Applicable Margin.

(c) (i) If all or a portion of the principal amount of any Revolving Credit Loan or Reimbursement Obligation shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum that is equal to (x) in the case of the Revolving Credit Loans, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this Section plus 2% or (y) in the case of Reimbursement Obligations, the rate applicable to Base Rate Loans plus 2%, and (ii) if all or a portion of any interest payable on any Revolving Credit Loan or Reimbursement Obligation or any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum equal to the rate then applicable to Base Rate Loans plus 2%, in each case, with respect to clauses (i) and (ii) above, from the date of such non-payment until such amount is paid in full (after as well as before judgment).

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to paragraph (c) of this Section shall be payable from time to time on demand.

2.11. Computation of Interest and Fees. (a) Interest, fees and commissions payable pursuant hereto shall be calculated on the basis of a 360-day year for the actual days elapsed, except that, with respect to Base Rate Loans the rate of interest on which is calculated on the basis of the Prime Rate, the interest thereon shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Revolving Credit Loan resulting from a change in the Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.10(a).

2.12. Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Revolving Credit Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (y) any Revolving Credit Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans shall be converted, on the last day of the then current Interest Period with respect thereto, to Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Revolving Credit Loans to Eurodollar Loans.

2.13. Pro Rata Treatment and Payments. (a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any commitment fee and any reduction of the Revolving Credit Commitments of the Lenders shall be made pro rata according to the respective Revolving Credit Percentages of the Lenders. Each payment (other than prepayments) in respect of principal or interest in respect of the Revolving Credit Loans, each payment in respect of fees payable hereunder, and each payment in respect of Reimbursement Obligations, shall be applied to the amounts of such obligations owing to the Lenders pro rata according to the respective amounts then due and owing to the Lenders.

(b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Revolving Credit Loans shall be allocated among the Lenders pro rata based on the outstanding principal amounts of the Revolving Credit Loans then held by the Lenders.

(c) The application of any payment of Revolving Credit Loans (including mandatory prepayments but excluding optional prepayments) shall be made, first, to Base Rate Loans and, second, to Eurodollar Loans. The application of optional prepayments shall be as directed by the Borrower. Each payment of the Revolving Credit Loans (except in the case of Base Rate Loans) shall be accompanied by accrued interest to the date of such payment on the amount paid.

(d) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest, fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Payment Office, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two sentences, interest thereon shall be payable at the then applicable rate during such extension.

(e) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days of such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to Base Rate Loans, on demand, from the Borrower.

(f) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment being made hereunder that the Borrower will not make such payment to the Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days of such required date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the Administrative Agent or any Lender against the Borrower.

2.14. Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 2.15 and changes in the rate of tax on the overall net income of such Lender);

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate hereunder; or

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled provided that the Borrower shall not be required to compensate a Lender pursuant to this paragraph for any amounts incurred more than six months prior to the date on which such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; and provided further that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction; provided that the Borrower shall not be required to compensate a Lender pursuant to this paragraph for any amounts incurred more than six months prior to the date on which such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor; and provided further that, if the circumstances giving rise to such claim have a retroactive effect, then such six-month period shall be extended to include the period of such retroactive effect. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall promptly notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled.

(c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant to this Section shall survive the termination of this Agreement and the payment of the Revolving Credit Loans and all other amounts payable hereunder.

2.15. Taxes. (a) All payments made by the Borrower 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, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, 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 the Administrative Agent or any Lender as a result of a present or

former connection between the Administrative Agent or such Lender 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 the Administrative Agent’s or such Lender’s 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, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or Other Taxes are required to be withheld from any amounts payable to the Administrative Agent or any Lender hereunder, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such Lender’s failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender at the time the Lender becomes a party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this Section 2.15(a).

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for the account of the relevant Agent or Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower 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 a result of any such failure. The agreements in this Section 2.15 shall survive the termination of this Agreement and the payment of the Revolving Credit Loans and all other amounts payable hereunder.

(d) Each Lender (or Transferee) that is not a U.S. Person as defined in Section 7701(a)(30) of the Code (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8EC1, or, in the case of a Non-U.S. Lender claiming 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 statement substantially in the form of Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors thereto properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall

deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(e) A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

2.16. Indemnity. The Borrower agrees to indemnify each Lender and to hold each Lender harmless from any loss or expense that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment or conversion of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Revolving Credit Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. A certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Revolving Credit Loans and all other amounts payable hereunder.

2.17. Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be canceled and (b) such Lender’s Revolving Credit Loans then outstanding as Eurodollar Loans, if

any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Revolving Credit Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.16.

2.18. Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Section 2.14, 2.15(a) or 2.17 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for any Revolving Credit Loans affected by such event with the object of avoiding the consequences of such event; provided, that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of any Borrower or the rights of any Lender pursuant to Section 2.14, 2.15(a) or 2.17.

3.1. L/C Commitment. (a) Subject to the terms and conditions hereof, the Issuing Lender, in reliance on the agreements of the other Lenders set forth in Section 3.4(a), agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower on any Business Day during the Revolving Credit Commitment Period in such form as may be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall not issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the aggregate amount of the Available Revolving Credit Commitments would be less than zero. Each Letter of Credit shall (i) be denominated in Dollars, (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the date which is five Business Days prior to the Revolving Credit Termination Date and (iii) only be payable on a sight basis with conforming certificates, if applicable.

(b) The Issuing Lender shall not at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause the Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law.

3.2. Procedure for Issuance of Letter of Credit. The Borrower may from time to time request that the Issuing Lender issue a Letter of Credit by delivering to the Issuing Lender (with a copy to the Administrative Agent) at its address for notices specified herein an Application therefor, completed to the satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as the Issuing Lender may request. Upon receipt of any Application, the Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly (but in no event more than five Business Days following the receipt of such Application) issue the Letter of Credit requested thereby by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by the Issuing Lender and the Borrower (but in no event shall the Issuing Lender be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and

information relating thereto). Promptly after issuance by the Issuing Lender of a Letter of Credit, the Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower. The Issuing Lender shall, within three days of such issuance, give to the Administrative Agent notice of the issuance of each Letter of Credit (including the amount thereof). Upon the written request of any Lender, the Administrative Agent will, within three Business Days of such request, inform such Lender of the aggregate drawable amount of all Letters of Credit outstanding on the date of such request.

3.3. Fees and Other Charges. (a) The Borrower will pay to the Administrative Agent, for the account of the Lenders, a fee on the aggregate drawable amount of all outstanding Letters of Credit at a per annum rate equal to the Applicable Margin then in effect with respect to Eurodollar Loans, to be shared ratably among the Lenders in accordance with their respective Revolving Credit Percentages and payable quarterly in arrears on each L/C Fee Payment Date after the issuance date.

(b) In addition to the foregoing fees, the Borrower shall pay to the Issuing Lender for its own account a fronting fee for each outstanding Letter of Credit, equal to the greater of (x) ¹/4 of 1.00% per annum on the aggregate drawable amount of such Letter of Credit and (y) $500. Such fronting fees shall be payable quarterly in arrears on each L/C Fee Payment Date and shall be nonrefundable.

(c) In addition to the foregoing fees, the Borrower shall pay or reimburse the Issuing Lender for such normal and customary costs and expenses as are incurred or charged by the Issuing Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit.

3.4. L/C Participations. (a) The Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce the Issuing Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant’s own account and risk an undivided interest equal to such L/C Participant’s Revolving Credit Percentage in the Issuing Lender’s obligations and rights under each Letter of Credit issued hereunder and the amount of each drawing paid by the Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with the Issuing Lender that, if a drawing is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrower in accordance with the terms of this Agreement, such L/C Participant shall pay to the Issuing Lender upon demand at the Issuing Lender’s address for notices specified herein an amount equal to such L/C Participant’s Revolving Credit Percentage of the amount of such drawing, or any part thereof, that is not so reimbursed.

(b) If any amount required to be paid by any L/C Participant to the Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by the Issuing Lender under any Letter of Credit is paid to the Issuing Lender within three Business Days after the date such payment is due, such L/C Participant shall pay to the Issuing Lender on demand an amount equal to the product of (i) such amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such payment is required to the date on which such payment is immediately available to the Issuing Lender, times

(iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any such amount required to be paid by any L/C Participant pursuant to Section 3.4(a) is not made available to the Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, the Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to Base Rate Loans. A certificate of the Issuing Lender submitted to any L/C Participant with respect to any amounts owing under this Section shall be conclusive in the absence of manifest error.

(c) Whenever, at any time after the Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its pro rata share of such payment in accordance with Section 3.4(a), the Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of collateral applied thereto by the Issuing Lender), or any payment of interest on account thereof, the Issuing Lender will distribute to such L/C Participant its pro rata share thereof; provided, however, that in the event that any such payment received by the Issuing Lender shall be required to be returned by the Issuing Lender, such L/C Participant shall return to the Issuing Lender the portion thereof previously distributed by the Issuing Lender to it.

3.5. Reimbursement Obligation of the Borrower. The Borrower agrees to reimburse the Issuing Lender on the next Business Day after each date on which the Issuing Lender notifies the Borrower of the date and amount of a drawing presented under any Letter of Credit and paid by the Issuing Lender for the amount of (a) such drawing so paid and (b) any taxes, fees, charges or other costs or expenses incurred by the Issuing Lender in connection with such payment (the amounts described in the foregoing clauses (a) and (b) in respect of any drawing, collectively, the “Payment Amount”). Each such payment shall be made to the Issuing Lender at its address for notices specified herein in lawful money of the United States of America and in immediately available funds. Interest shall be payable on each Payment Amount from the date of the applicable drawing until payment in full at the rate set forth in (i) until the second Business Day following the date of the applicable drawing, Section 2.10(b) and (ii) thereafter, Section 2.10(c). Each drawing under any Letter of Credit shall (unless an event of the type described in clause (i) or (ii) of Section 8(f) shall have occurred and be continuing with respect to the Borrower, in which case the procedures specified in Section 3.4 for funding by L/C Participants shall apply) constitute a request by the Borrower to the Administrative Agent for a borrowing pursuant to Section 2.2 of Base Rate Loans in the amount of such drawing. The Borrowing Date with respect to such borrowing shall be the first date on which a borrowing of Revolving Credit Loans could be made pursuant to Section 2.2 if the Administrative Agent had received a notice of such borrowing at the time the Administrative Agent receives notice from the Issuing Lender of such drawing under such Letter of Credit.

3.6. Obligations Absolute. The Borrower’s obligations under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against the Issuing Lender, any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees with the Issuing Lender that the Issuing Lender shall not be responsible for, and the Borrower’s Reimbursement Obligations under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though

such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. The Issuing Lender shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Issuing Lender. The Borrower agrees that any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct and in accordance with the standards or care specified in the Uniform Commercial Code in effect in the State of New York or, if applicable to such Letter of Credit, the Uniform Customs and Practice for Documentary Credits or the International Standby Practices as published by the International Chamber of Commerce most recently at the time of issuance of any Letter of Credit, shall be binding on the Borrower and shall not result in any liability of the Issuing Lender to the Borrower.

3.7. Letter of Credit Payments. If any drawing shall be presented for payment under any Letter of Credit, the Issuing Lender shall promptly notify the Borrower of the date and amount thereof. The responsibility of the Issuing Lender to the Borrower in connection with any drawing presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each drawing) delivered under such Letter of Credit in connection with such presentment appear on their face to be in conformity with such Letter of Credit.

3.8. Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply.

(a) The Borrower agrees to reimburse GE Capital in immediately available funds in the amount of any payment made by GE Capital under a Swap Related L/C (such reimbursement obligation, whether contingent upon payment by GE Capital under the Swap Related L/C or otherwise, being herein called a “Swap Related Reimbursement Obligation”). No Swap Related Reimbursement Obligation for any Swap Related L/C may exceed the amount of the payment obligations owed by the Borrower under the interest rate protection or hedging agreement or transaction supported by the Swap Related L/C.

(b) A Swap Related Reimbursement Obligation shall be due and payable by the Borrower within one (1) Business Day after the date on which the related payment is made by GE Capital under the Swap Related L/C.

(c) Any Swap Related Reimbursement Obligation shall, during the period in which it is unpaid, bear interest at the rate per annum equal to the Eurodollar Base Rate plus one percent (1%), as if the unpaid amount of the Swap Related Reimbursement Obligation were a Eurodollar Loan, and not at any otherwise applicable rate. Such interest shall be payable upon

demand. The following additional provisions apply to the calculation and charging of interest by reference to the Eurodollar Base Rate:

(i) The Eurodollar Base Rate shall be determined for each successive one-month Interest Period during which the Swap Related Reimbursement Obligation is unpaid, notwithstanding the occurrence of any Event of Default and even if the Interest Period were to extend beyond the Revolving Credit Termination Date.

(ii) If a Swap Related Reimbursement Obligation is paid during a monthly period for which the Eurodollar Base Rate is determined, interest shall be prorated and charged for the portion of the monthly period during which the Swap Related Reimbursement Obligation was unpaid. Section 2.6 shall not apply to any payment of a Swap Related Reimbursement Obligation during the monthly period.

(d) Except as provided in the foregoing provisions of this Section 3A and in Section 10.5, the Borrower shall not be obligated to pay to GE Capital or any of its Affiliates any letter of credit fee (including, but not limited to the fee described in Section 3.3), or any other fees, charges or expenses, in respect of a Swap Related L/C or arranging for any interest rate protection or hedging agreement or transaction supported by the Swap Related L/C. GE Capital and its Affiliates shall look to the beneficiary of a Swap Related L/C for payment of any such letter of credit fees or other fees, charges or expenses and such beneficiary may factor such fees, charges, or expenses into the pricing of any interest rate protection or hedging arrangement or transaction supported by the Swap Related L/C.

(e) If any Swap Related L/C is revocable prior to its scheduled expiry date, GE Capital agrees not to revoke the Swap Related L/C unless the Revolving Credit Termination Date or an Event of Default has occurred.

(f) GE Capital or any of its Affiliates shall be permitted to (i) provide confidential or other information furnished to it by any of the Loan Parties (including, without limitation, copies of any documents and information in or referred to in the Loan Documents, financial statements and Compliance Certificates) to a beneficiary or potential beneficiary of a Swap Related L/C and (ii) receive confidential or other information from the beneficiary or potential beneficiary relating to any agreement or transaction supported or to be supported by the Swap Related L/C. However, no confidential information shall be provided to any Person under this paragraph unless the Person has agreed to comply with the covenant substantially as contained in Section 10.14.

To induce the Administrative Agent and the Lenders to enter into this Agreement and to make Revolving Credit Loans and issue or participate in the Letters of Credit, the Borrower hereby represents and warrants to the Administrative Agent and each Lender that:

4.1. Financial Condition. (a) The unaudited pro forma consolidated balance sheets of the Parent and the Borrower and their consolidated Subsidiaries as of September 30, 2005 (including the notes thereto) (the “Pro Forma Balance Sheets”), and the unaudited pro

forma consolidated statement of income of the Borrower and its consolidated Subsidiaries for the four fiscal quarter period ended on such date (including the pro forma notes thereto) (the “Pro Forma Income Statement”), copies of which have heretofore been furnished to each Lender, have been prepared giving effect to the transactions contemplated hereby. The Pro Forma Balance Sheets and the Pro Forma Income Statement have been prepared based on the best information available to the Parent and the Borrower, as the case may be, as of the date of delivery thereof, and present fairly in all material respects on a pro forma basis the estimated financial position and results of operations of the Parent and the Borrower and their consolidated Subsidiaries as of, and for the four fiscal quarter period ended on, September 30, 2005, assuming that the events specified in the preceding sentence had actually occurred at such date.

(b) The audited consolidated balance sheets of the Parent and its Subsidiaries as at December 31, 2004 and December 31, 2003 and the related statements of income and of cash flows for the fiscal years ended on such dates, reported on by and accompanied by an unqualified report from Ernst & Young LLP, present fairly in all material respects the consolidated financial condition of the Parent and its Subsidiaries as of such dates, and the consolidated results of its operations and its consolidated cash flows for the respective fiscal years then ended. The unaudited consolidated balance sheet of the Parent and its Subsidiaries as at September 30, 2005, and the related unaudited consolidated statements of income and cash flows for the nine-month period ended on such date present fairly in all material respects the consolidated financial condition of the Parent and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the nine-month period then ended (subject to normal year-end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). The Parent and its Subsidiaries do not have any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or unusual forward or long-term commitments, including, without limitation, any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the period from December 31, 2004 to and including the date hereof there has been no Disposition by the Parent of any material part of its business or Property other than pursuant to the New Securitization Arrangements.

4.2. No Change. Since December 31, 2004 there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect.

4.3. Corporate Existence; Compliance with Law. Each of the Borrower and its Subsidiaries (a) is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) has the corporate power and authority, and the legal right, to own and operate its Property, to lease the Property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign corporation and in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification except to the extent the failure to be so qualified could not, in the aggregate, reasonably be expected to have a Material Adverse Effect and (d) is in compliance with all Requirements of Law except to the extent that the failure

to comply therewith could not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

4.4. Corporate Power; Authorization; Enforceable Obligations. Each Loan Party has the corporate power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of the Borrower, to borrow hereunder. Each Loan Party has taken all necessary corporate action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of the Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or with the execution, delivery, performance, validity or enforceability of this Agreement or any of the Loan Documents, except the filings referred to in Section 4.19. Each Loan Document has been duly executed and delivered on behalf of each Loan Party party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid and binding obligation of each Loan Party party thereto, enforceable against each such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

4.5. No Legal Bar. The execution, delivery and performance of this Agreement and the other Loan Documents, the issuance of Letters of Credit, the borrowings hereunder and the use of the proceeds thereof (a) will not violate any Requirement of Law or any Contractual Obligation of the Borrower or any of its Subsidiaries except (x) as could not, in the aggregate, reasonably be expected to have a Material Adverse Effect and (y) for such Contractual Obligations pursuant to which the Administrative Agent is required to execute and deliver a non-disturbance agreement and (b) will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents). No Requirement of Law or Contractual Obligation applicable to the Borrower or any of its Subsidiaries could reasonably be expected to have a Material Adverse Effect.

4.6. No Material Litigation. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any of its Subsidiaries or against any of their respective properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) that could reasonably be expected to have a Material Adverse Effect.

4.7. No Default. Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any of its Contractual Obligations in any respect that could reasonably be expected to have a Material Adverse Effect. No Default or Event of Default has occurred and is continuing.

4.8. Ownership of Property; Liens. Each of the Borrower and its Subsidiaries has title in fee simple to, a valid leasehold interest in, or an easement, license or permit to occupy, all its real property, and good title to, a valid leasehold interest in, or an easement, license or permit to occupy, all its other Property, and none of such Property is subject to any Lien except as permitted by Section 7.3.

4.9. Intellectual Property. The Borrower and each of its Subsidiaries owns, or is licensed to use, all Intellectual Property necessary for the conduct of its business as currently conducted. No material claim has been asserted and is pending by any Person challenging or questioning the use of any Intellectual Property or the validity or effectiveness of any Intellectual Property, nor does the Borrower know of any valid basis for any such claim. The use of Intellectual Property by the Borrower and its Subsidiaries does not infringe on the rights of any Person in any material respect.

4.10. Taxes. Each of the Borrower and each of its Subsidiaries has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its Property and all other taxes, fees or other charges imposed on it or any of its Property by any Governmental Authority and due and payable (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or its Subsidiaries, as the case may be) except for state and local tax returns relating to taxes in an aggregate amount not exceeding $2,000,000 at any one time outstanding (after applying loss probability factors in accordance with GAAP) and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or its Subsidiaries, as the case may be; no tax Lien has been filed, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge.

4.11. Federal Regulations. No part of the proceeds of any Revolving Credit Loans will be used for “purchasing” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect or for any purpose that violates the provisions of the Regulations of the Board. If requested by any Lender or the Administrative Agent, the Borrower will furnish to the Administrative Agent and each Lender a statement to the foregoing effect in conformity with the requirements of FR Form G-3 or FR Form U-1 referred to in Regulation U.

4.12. Labor Matters. There are no strikes or other labor disputes against the Borrower or any of its Subsidiaries pending or, to the knowledge of the Borrower, threatened that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect. Hours worked by and payment made to employees of the Borrower and its Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable Requirement of Law dealing with such matters that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect. All payments due from the Borrower or any of its Subsidiaries on account of employee health and welfare insurance that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect if not paid have been paid or accrued as a liability on the books of the Borrower or the relevant Subsidiary.

4.13. ERISA. Neither a Reportable Event nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has occurred during the five-year period prior to the date on which this representation is made or deemed made with respect to any Plan, and each Plan has complied in all material respects with the applicable provisions of ERISA and the Code. No termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by a material amount. Neither the Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither the Borrower nor any Commonly Controlled Entity would become subject to any material liability under ERISA if the Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the date on which this representation is made or deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.

4.14. Investment Company Act; Other Regulations. No Loan Party is an “investment company,” or a company “controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended. No Loan Party is subject to regulation under any Requirement of Law (other than Regulation X of the Board) which limits its ability to incur Indebtedness.

4.15. Subsidiaries. (a) The Subsidiaries listed on Schedule 4.15 constitute all the Subsidiaries of the Borrower as of the Effective Date. Schedule 4.15 sets forth as of the Effective Date the name and jurisdiction of incorporation of each Subsidiary and, as to each such Subsidiary, the percentage of each class of Capital Stock owned by any Loan Party.

(b) There are no outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments (other than stock options granted to employees or directors and directors’ qualifying shares) of any nature relating to any Capital Stock of the Borrower or any Subsidiary.

4.16. Use of Proceeds. The proceeds of the Revolving Credit Loans made on or after the Effective Date shall be used to finance (i) the acquisition of Qualified Tower Portfolios and construction of Towers permitted by Section 7.7, (ii) to make Restricted Payments to Holdings permitted by Section 7.6 or (iii) other working capital needs and general corporate purposes of the Borrower and its Subsidiaries.

4.17. Environmental Matters. Other than exceptions to any of the following that could not, individually or in the aggregate, reasonably be expected to result in a Material Environmental Loss:

(a) the Borrower and its Subsidiaries: (i) are, and within the period of all applicable statutes of limitation have been, in compliance with all applicable Environmental Laws; (ii) hold all Environmental Permits (each of which is in full force and effect) required for

any of their current or intended operations or for any property owned, leased, or otherwise operated by any of them; (iii) are, and within the period of all applicable statutes of limitation have been, in compliance with all of their Environmental Permits; and (iv) reasonably believe that: each of their Environmental Permits will be timely renewed and complied with, without material expense; any additional Environmental Permits that may be required of any of them will be timely obtained and complied with, without material expense; and compliance with any Environmental Law that is or is expected to become applicable to any of them will be timely attained and maintained, without material expense.

(b) Materials of Environmental Concern are not present at, on, under, in, or about any real property now or formerly owned, leased or operated by the Borrower or any of its Subsidiaries, or at any other location (including, without limitation, any location to which Materials of Environmental Concern have been sent for re-use or recycling or for treatment, storage, or disposal) which could reasonably be expected to (i) give rise to liability of the Borrower or any of its Subsidiaries under any applicable Environmental Law or otherwise result in costs to the Borrower or any of its Subsidiaries, or (ii) interfere with the Borrower’s or any of its Subsidiaries’ continued operations, or (iii) impair the fair saleable value of any real property owned or leased by the Borrower or any of its Subsidiaries.

(c) There is no judicial, administrative, or arbitral proceeding (including any notice of violation or alleged violation) under or relating to any Environmental Law to which the Borrower or any of its Subsidiaries is, or to the knowledge of the Borrower or any of its Subsidiaries will be, named as a party that is pending or, to the knowledge of the Borrower or any of its Subsidiaries, threatened; and to the knowledge of the Borrower or any of its Subsidiaries, there are no judicial, administrative, or arbitral proceedings under or relating to any Environmental Law pending or threatened against any Person, other than the Borrower or any of its Subsidiaries, that could reasonably be expected to affect the Borrower or any of its Subsidiaries.

(d) Neither the Borrower nor any of its Subsidiaries has received any written request for information, or been notified that it is a potentially responsible party under or relating to the federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, or any similar Environmental Law, or with respect to any Materials of Environmental Concern.

(e) Neither the Borrower nor any of its Subsidiaries has entered into or agreed to any consent decree, order, or settlement or other agreement, or is subject to any judgment, decree, or order or other agreement, in any judicial, administrative, arbitral, or other forum for dispute resolution, relating to compliance with or liability under any Environmental Law.

(f) Neither the Borrower nor any of its Subsidiaries has assumed or retained, by contract or operation of law, any liabilities of any kind, fixed or contingent, known or unknown, under any Environmental Law or with respect to any Material of Environmental Concern.

4.18. Accuracy of Information, etc. No statement or information contained in this Agreement, any other Loan Document or any other written document, certificate or

statement furnished to the Administrative Agent or the Lenders or any of them, by or on behalf of any Loan Party for use in connection with the transactions contemplated by this Agreement or the other Loan Documents, contained as of the date such statement, information, document or certificate was so furnished, any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements contained herein or therein not misleading. The projections and pro forma financial information contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount. There is no fact actually known to any Loan Party that could reasonably be expected to have a Material Adverse Effect that has not been expressly disclosed herein, in the other Loan Documents or in any other documents, certificates and statements furnished to the Administrative Agent and the Lenders for use in connection with the transactions contemplated hereby and by the other Loan Documents.

4.19. Security Documents. The Guarantee and Collateral Agreement is effective to create in favor of the Administrative Agent, for the benefit of the Secured Parties, a legal, valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case of the Pledged Stock described in the Guarantee and Collateral Agreement, stock certificates representing such Pledged Stock having been delivered to the Administrative Agent, in the case of the Account Collateral, upon the execution of the Deposit Account Control Agreement by the parties thereto, and in the case of the other Collateral described in the Guarantee and Collateral Agreement, financing statements in appropriate form having been filed in the offices specified on Schedule 4.19 and such other filings as are specified on Schedule 3 to the Guarantee and Collateral Agreement having been duly completed, the Guarantee and Collateral Agreement constitutes a fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties in such Collateral and the proceeds thereof, as security for the Obligations (as defined in the Guarantee and Collateral Agreement), in each case prior and superior in right to any other Person (except, in the case of Collateral other than Pledged Stock or the Account Collateral, Liens permitted by Section 7.3 and except as provided in the Deposit Account Control Agreement). Notwithstanding the foregoing, it is understood that fixture filings are not being made in respect of Tower or office locations.

4.20. Solvency. Each Loan Party is, and after giving effect to the incurrence of all Indebtedness and obligations being incurred in connection herewith will be and will continue to be, Solvent.

4.21. Real Property Leases. The present and contemplated use of the real property owned or leased by the Borrower or any of its Subsidiaries for the operation of Towers is in compliance in all material respects with all applicable zoning ordinances and regulations and other laws and regulations where failure so to comply would result, or create reasonable risk of resulting, in a Material Adverse Effect. Each lease pursuant to which the Borrower or any of its Subsidiaries, as lessee, acquired rights in real property upon which any Tower is situated is in full force and effect, the Borrower or such Subsidiary has all rights of the lessee thereunder, there has been no default in the performance of any of its terms or conditions by the Borrower or any such Subsidiary nor (to the best of the Borrower’s knowledge) any other party thereto, and no

claims of default have been asserted with respect thereto where such default would result, or create a reasonable risk of resulting, in a Material Adverse Effect.

4.22. FCC and FAA Matters; State Regulatory Compliance. (a) The Borrower (i) has duly and timely filed all material reports, registrations and other material filings, if any, which are required to be filed by it or any of its Subsidiaries under the Communications Act or any other applicable law, rule or regulation of any Governmental Authority, including the FCC and the FAA, the non-filing of which would not result, or be reasonably likely to result, in a Material Adverse Effect and (ii) is in compliance with all such laws, rules, regulations and ordinances, including those promulgated by the FCC and the FAA, to the extent the non-compliance with which would result, or be reasonably likely to result, in a Material Adverse Effect. All information provided by or on behalf of the Borrower or any Affiliate in any material filing, if any, with the FCC and the FAA relating to the business of the Borrower and its Subsidiaries was, to the knowledge of such Person at the time of filing, complete and correct in all material respects when made, and the FCC and the FAA have been notified of any substantial or significant changes in such information as may be required in accordance with applicable Requirements of Law.

(b) The Borrower and its Subsidiaries have all permits, certificates, licenses, tariff approvals and other authorizations from all state and federal Governmental Authorities required to conduct their current business except for such permits, certificates, licenses, tariff approvals and other authorizations as could not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

Notwithstanding any provision to the contrary elsewhere in this Agreement, no Agent shall have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, 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 any Agent.

9.2. Delegation of Duties. Each Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be

entitled to advice of counsel concerning all matters pertaining to such duties. No Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

9.3. Exculpatory Provisions. Neither any Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party.

9.4. Reliance by Agents. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to any of the Loan Parties), independent accountants and other experts selected by such Agent. The Agents may deem and treat the payee of any Note as the owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 10.6 and all actions required by such Section in connection with such transfer shall have been taken. Each Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Revolving Credit Loans.

9.5. Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless such Agent shall have received notice from a Lender, Holdings or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Administrative Agent shall receive such a notice, the Administrative Agent shall give

notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement); provided that unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders.

9.6. Non-Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that neither any of the Agents nor any of their respective officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own decision to make its Revolving Credit Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan Party or any affiliate of a Loan Party that may come into the possession of such Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates.

9.7. Indemnification. The Lenders agree to indemnify each Agent in its capacity as such (to the extent not reimbursed by a Loan Party and without limiting the obligation of each Loan Party to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Revolving Credit Commitments shall have terminated and the Revolving Credit Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to such date), for, and to save each Agent harmless from and against, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including, without limitation, at any time following the payment of the Revolving Credit Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Revolving Credit Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender

shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from such Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Revolving Credit Loans and all other amounts payable hereunder.

9.8. Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Revolving Credit Loans made or renewed by it and with respect to any Letter of Credit issued or participated in by it, each Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent in its individual capacity.

9.9. Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon fifteen days’ notice to the Lenders and the Borrower. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent, and the term “Administrative Agent” shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Revolving Credit Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is fifteen days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent as provided for above. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents.

9.10. Authorization to Release Liens. The Administrative Agent is hereby irrevocably authorized by each of the Lenders to release any Lien covering any Property of the Borrower or any of its Subsidiaries that is the subject of a Disposition which is permitted by this Agreement or which has been consented to in accordance with Section 10.1 and to release any obligations under any Loan Document of any Person being Disposed of in such Disposition or which has been consented to in accordance with Section 10.1 or which is converted to a special purpose entity pursuant to the Second Securitization Arrangements so long as the requirements of Section 2.7(d) are complied with in connection therewith.

9.11. The Syndication Agent; Co-Documentation Agents. Neither the Syndication Agent nor the Co-Documentation Agents, in their respective capacities as such, shall

have any duties or responsibilities, or shall incur any liability, under this Agreement and the other Loan Documents.

10.1. Amendments and Waivers. Neither this Agreement or any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.1. The Required Lenders and each Loan Party party to the relevant Loan Document may, or (with the written consent of the Required Lenders) the Administrative Agent and each Loan Party party to the relevant Loan Document may, from time to time, (a) enter into written amendments, supplements or modifications hereto and to the other Loan Documents (including amendments and restatements hereof or thereof) for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Loan Parties hereunder or thereunder or (b) waive, on such terms and conditions as may be specified in the instrument of waiver, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall:

(vii) impose restrictions on assignments and participations that are more restrictive than, or additional to, those set forth in Section 10.6, without the consent of all Lenders.

Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Agents and all future holders of the Revolving Credit Loans. In the case of any waiver, the Loan Parties, the Lenders and the Agents shall be restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. Any such waiver, amendment, supplement or modification shall be effected by a written instrument signed by the parties required to sign pursuant to the foregoing provisions of this Section; provided, that delivery of an executed signature page of any such instrument by facsimile transmission shall be effective as delivery of a manually executed counterpart thereof.

10.2. Notices. All notices, requests and demands to or upon the respective parties hereto to be effective shall be in writing (including by telecopy), and, unless otherwise expressly provided herein, shall be deemed to have been duly given or made when delivered, or three Business Days after being deposited in the mail, postage prepaid, or, in the case of telecopy notice, when received, addressed (a) in the case of the Borrower and the Administrative Agent, as follows and (b) in the case of the Lenders, as set forth in an administrative questionnaire delivered to the Administrative Agent or on Schedule I to the Lender Addendum to which such Lender is a party or, in the case of a Lender which becomes a party to this Agreement pursuant to an Assignment and Acceptance, in such Assignment and Acceptance or (c) in the case of any party, to such other address as such party may hereafter notify to the other parties hereto:

provided that any notice, request or demand to or upon the Administrative Agent, any Issuing Lender or any Lender shall not be effective until received.

10.3. No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of any Agent or any Lender, any right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

10.4. Survival of Representations and Warranties. All representations and warranties made herein, in the other Loan Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Revolving Credit Loans and other extensions of credit hereunder.

10.5. Payment of Expenses. The Borrower agrees (a) to pay or reimburse the Agents for all their reasonable out-of-pocket costs and expenses incurred in connection with the syndication of the Revolving Credit Facility and the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, without limitation, the reasonable fees and disbursements and other charges of counsel to the Administrative Agent and the charges of Intralinks, (b) to pay or reimburse each Lender and the Agents for all their costs and expenses incurred in connection with the enforcement or preservation of any rights under this Agreement, the other Loan Documents and any other documents prepared in connection herewith or therewith, including, without limitation, the fees and disbursements of counsel (including the allocated fees and disbursements and other charges of in-house counsel) to each Lender and of counsel to the Agents, (c) to pay, indemnify, or reimburse each Lender and the Agents for, and hold each Lender and the Agents harmless from, any and all recording and filing fees and any and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify, or reimburse each Lender,

the Agents, their respective affiliates, and their respective officers, directors, trustees, employees, advisors, agents and controlling persons (each, an “Indemnitee”) for, and hold each Indemnitee harmless from and against any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other documents, including, without limitation, any of the foregoing relating to the use of proceeds of the Revolving Credit Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of Parent, any of its Subsidiaries or any property at any time owned, leased, or in any way used by Parent, any Subsidiary of Parent or any other entity for which Parent or any of its Subsidiaries is alleged to be responsible, and the fees and disbursements and other charges of legal counsel in connection with claims, actions or proceedings by any Indemnitee against any Loan Party hereunder (all the foregoing in this clause (d), collectively, the “Indemnified Liabilities”), provided, that the Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee. No Indemnitee shall be liable for any damages arising from the use by unauthorized persons of information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons or for any special, indirect, consequential or punitive damages in connection with the Facilities. Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries so to waive, all rights for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might have by statute or otherwise against any Indemnitee. All amounts due under this Section shall be payable not later than 30 days after written demand therefor. Statements payable by the Borrower pursuant to this Section shall be submitted to Pam Kline (Telephone No. (561) 226-9232) (Fax No. (561) 989–2940), at the address of the Borrower set forth in Section 10.2, or to such other Person or address as may be hereafter designated by the Borrower in a written notice to the Administrative Agent. The agreements in this Section shall survive repayment of the Revolving Credit Loans and all other amounts payable hereunder.

10.6. Successors and Assigns; Participations and Assignments. (a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Agents, all future holders of the Revolving Credit Loans and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Agents and each Lender.

(b) Any Lender may, without the consent of the Borrower, in accordance with applicable law, at any time sell to one or more banks, financial institutions or other entities (each, a “Participant”) participating interests in any Revolving Credit Loan owing to such Lender, any Revolving Credit Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely

responsible for the performance thereof, such Lender shall remain the holder of any such Revolving Credit Loan for all purposes under this Agreement and the other Loan Documents, and the Borrower and the Agents shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by any Loan Party therefrom, except to the extent that such amendment, waiver or consent would require the consent of all Lenders pursuant to Section 10.1. The Borrower agrees that if amounts outstanding under this Agreement and the Revolving Credit Loans are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as if such Participant were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.14, 2.15 and 2.16 with respect to its participation in the Revolving Credit Commitments and the Revolving Credit Loans outstanding from time to time as if such Participant were a Lender; provided that, in the case of Section 2.15, such Participant shall have complied with the requirements of said Section and provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred.

(c) Any Lender (an “Assignor”) may, in accordance with applicable law and upon written notice to the Administrative Agent, at any time and from time to time assign to any Lender or any affiliate, Related Fund or Control Investment Affiliate thereof or, with the consent of the Administrative Agent, the Issuing Lender and, other than upon the occurrence and during the continuance of a Default or Event of Default, the Borrower (which, in each case, shall not be unreasonably withheld or delayed), to an additional bank, financial institution or other entity (an “Assignee”) all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance, substantially in the form of Exhibit D, executed by such Assignee and such Assignor (and, where the consent of the Administrative Agent, the Issuing Lender or the Borrower is required pursuant to the foregoing provisions, by such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that no such assignment to an Assignee (other than any Lender, Related Fund or any affiliate of a Lender or Related Fund) shall be in an aggregate principal amount of less than $2,000,000 (other than in the case of an assignment of all of a Lender’s interests under this Agreement), unless otherwise agreed by the Borrower and the Administrative Agent; provided further that, after giving effect to such assignment, the aggregate principal amount of such Assignor’s Revolving Credit Commitment or Revolving Credit Loans shall be at least $2,000,000 (other than in the case of an assignment to a Related Fund or to an affiliate of such Assignor or of all of a Lender’s interests under this Agreement), unless otherwise agreed by the Borrower and the Administrative Agent. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights

and obligations of a Lender hereunder with Revolving Credit Commitments and/or Revolving Credit Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor’s rights and obligations under this Agreement, such Assignor shall cease to be a party hereto, except as to Section 2.14, 2.15 and 10.5). For purposes of the minimum assignment amounts set forth in this paragraph, multiple assignments by two or more Related Funds shall be aggregated. For the purposes of the minimum Revolving Credit Commitment and Revolving Credit Loans to be held by any Assignor after giving effect to any assignment, such amounts shall be aggregated in respect of each Lender and its affiliates or Related Fund, if any.

(d) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in Section 10.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Revolving Credit Commitment of, and principal amount of the Revolving Credit Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, each Agent and the Lenders shall treat each Person whose name is recorded in the Register as the owner of the Revolving Credit Loans and any Notes evidencing such Revolving Credit Loans recorded therein for all purposes of this Agreement. Any assignment of any Revolving Credit Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Revolving Credit Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer of the Note evidencing such Revolving Credit Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Notes shall be returned by the Administrative Agent to the Borrower marked “canceled.” The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(e) Upon its receipt of an Assignment and Acceptance executed by an Assignor and an Assignee (and, in any case where the consent of any other Person is required by Section 10.6(c), by each such other Person) together with payment to the Administrative Agent of a registration and processing fee of $3,500 (treating multiple, simultaneous assignments by or to two or more Related Funds as a single assignment) (except that no such registration and processing fee shall be payable (y) in connection with an assignment by or to any Agent or (z) in the case of an Assignee which is already a Lender or is an affiliate or Related Fund of a Lender or a Person under common management with a Lender), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Borrower. On or prior to such effective date, the Borrower, at its own expense, upon request, shall execute and deliver to the Administrative Agent (in exchange for the Note of the assigning Lender) a new Note to the order of such Assignee in an amount equal to the Revolving Credit Commitment assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Revolving Credit Commitment, upon request, a new Note to the order of the Assignor in an amount equal to the Revolving

Credit Commitment retained by it hereunder. Such new Note or Notes shall be dated the Effective Date and shall otherwise be in the form of the Note or Notes replaced thereby.

(f) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Revolving Credit Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests in Revolving Credit Loans and Notes, including, without limitation, any pledge or assignment by a Lender of any Revolving Credit Loan or Note to any Federal Reserve Bank in accordance with applicable law.

(g) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Revolving Credit Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Revolving Credit Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Revolving Credit Loan, the Granting Lender shall be obligated to make such Revolving Credit Loan pursuant to the terms hereof. The making of a Revolving Credit Loan by an SPC hereunder shall utilize the Revolving Credit Commitment of the Granting Lender to the same extent, and as if, such Revolving Credit Loan 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 indebtedness 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 proceedings under the laws of the United States or any state thereof. In addition, notwithstanding anything to the contrary in this Section 10.6(g), any SPC may (A) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Revolving Credit Loans to the Granting Lender, or with the prior written consent of the Borrower and the Administrative Agent (which consent shall not be unreasonably withheld) to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Revolving Credit Loans, and (B) disclose on a confidential basis any non-public information relating to its Revolving Credit Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC; provided that non-public information with respect to the Borrower may be disclosed only with the Borrower’s consent which will not be unreasonably withheld. This paragraph (g) may not be amended without the written consent of any SPC with Revolving Credit Loans outstanding at the time of such proposed amendment.

(h) Nothing contained in this Section 10.6 shall require the consent of any party for GE Capital to assign any of its rights in respect of any Swap Related Reimbursement Obligation.

10.7. Adjustments; Set-off. (a) Except to the extent that this Agreement provides for payments to be allocated to a particular Lender, if any Lender (a “Benefited Lender”) shall at any time receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Obligations, such Benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Obligations, or shall provide such other Lenders with the benefits of any such collateral, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and the Administrative Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application.

10.8. Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed signature page of this Agreement or of a Lender Addendum by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent.

10.9. Severability. 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, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

10.10. Integration. This Agreement and the other Loan Documents represent the entire agreement of the Borrower, the Agents and the Lenders with respect to the subject matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Agents or any Lender relative to subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents.

10.11. GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

10.12. Submission To Jurisdiction; Waivers. The Borrower hereby irrevocably and unconditionally:

(a) submits for itself and its Property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the courts of the State of New York, the courts of the United States of America for the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to the Borrower at its address set forth in Section 10.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, any right it may have to claim or recover in any legal action or proceeding referred to in this Section any special, exemplary, punitive or consequential damages.

(a) it has been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents;

(b) neither the Agents nor any Lender has any fiduciary relationship with or duty to the Borrower arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Agents and the Lenders, on one hand, and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Agents and the Lenders or among the Borrower and the Lenders.

10.14. Confidentiality; Public Disclosure. (a) Each of the Agents and the Lenders agrees to keep confidential all non-public information provided to it by any Loan Party

pursuant to this Agreement that is designated by such Loan Party as confidential; provided that nothing herein shall prevent any Agent or any Lender from disclosing any such information (i) to any Agent, any other Lender or any affiliate of any thereof, (ii) to any Participant or Assignee (each, a “Transferee”) or prospective Transferee that agrees to comply with the provisions of this Section or substantially equivalent provisions, (iii) any of its employees, directors, agents, attorneys, accountants and other professional advisors, (iv) any financial institution that is a direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section), (v) upon the request or demand of any Governmental Authority having jurisdiction over it, (vi) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Requirement of Law, (vii) in connection with any litigation or similar proceeding, (viii) that has been publicly disclosed other than in breach of this Section, (ix) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender or (x) in connection with the exercise of any remedy hereunder or under any other Loan Document.

(b) None of the Loan Parties shall issue any press release or other public disclosure (other than any filing required to be made with the SEC) using the name of any of the Lenders or any affiliate of a Lender in connection with this transaction without both (i) providing any such Lender with at least two (2) Business Days’ prior notice and (ii) obtaining the Lender’s or such Lender’s affiliate’s prior written consent. Nothing in the immediately preceding sentence shall prevent any disclosure of the name of any Lender or of any affiliate of such Lender to the extent (and only to the extent) required by any Requirement of Law, provided that, the person or entity making such disclosure shall nonetheless consult with the affected Lender or the relevant affiliate of such Lender prior to issuing such press release or other public disclosure.

(c) Notwithstanding the foregoing, the Lenders and their Affiliates shall have the right to (i) list and exhibit the Borrower’s name and logo, as provided by the Borrower from time to time, and describe the transaction that is the subject of this Agreement in their marketing materials and (ii) post such information, including, without limitation, a customary “tombstone,” on their web site.

10.15. Release of Collateral Security and Guarantee Obligations. (a) Notwithstanding anything to the contrary contained herein or in any other Loan Document, upon request of the Borrower in connection with any Disposition of Property permitted by the Loan Documents, the Administrative Agent shall (without notice to, or vote or consent of, any Lender, any affiliate of any Lender that is a party to any Specified Hedge Agreement or any issuer of a Swap Related L/C in its capacity as such) take such actions as shall be required to release its security interest in any Collateral being Disposed of in such Disposition and to release any guarantee obligations under any Loan Document of any Person being Disposed of in such Disposition or which is converted to a special purpose entity pursuant to the Second Securitization Arrangements so long as the requirements of Section 2.7(d) are complied with in connection therewith, to the extent necessary to permit consummation of such Disposition or substitutions in accordance with the Loan Documents.

(b) Notwithstanding anything to the contrary contained herein or any other Loan Document, when all Obligations (other than obligations in respect of any Specified Hedge Agreement and Swap Related Reimbursement Obligations) have been paid in full, all Revolving Credit Commitments have terminated or expired and no Letter of Credit shall be outstanding, upon request of the Borrower, the Administrative Agent shall (without notice to, or vote or consent of, any Lender, any affiliate of any Lender that is a party to any Specified Hedge Agreement or any issuer of a Swap Related L/C in its capacity as such) take such actions as shall be required to release its security interest in all Collateral, and to release all guarantee obligations under any Loan Document, whether or not on the date of such release there may be outstanding Obligations in respect of Specified Hedge Agreements or Swap Related Reimbursement Obligations. Any such release of guarantee obligations shall be deemed subject to the provision that such guarantee obligations shall be reinstated if after such release any portion of any payment in respect of the Obligations guaranteed thereby shall be rescinded or must otherwise be restored or returned upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or any Subsidiary Guarantor, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, the Borrower or any Subsidiary Guarantor or any substantial part of its property, or otherwise, all as though such payment had not been made.

10.16. Accounting Changes. In the event that any “Accounting Change” (as defined below) shall occur and such change results in a change in the method of calculation of financial covenants, standards or terms in this Agreement, then the Borrower and the Administrative Agent agree to enter into negotiations in order to amend such provisions of this Agreement so as to equitably reflect such Accounting Changes with the desired result that the criteria for evaluating the Borrower’s financial condition shall be the same after such Accounting Changes as if such Accounting Changes had not been made. Until such time as such an amendment shall have been executed and delivered by the Borrower, the Administrative Agent and the Required Lenders, all financial covenants, standards and terms in this Agreement shall continue to be calculated or construed as if such Accounting Changes had not occurred. “Accounting Changes” refers to changes in accounting principles required by the promulgation of any rule, regulation, pronouncement or opinion by the Financial Accounting Standards Board of the American Institute of Certified Public Accountants or, if applicable, the SEC.

10.17. Delivery of Lender Addenda. Each initial Lender shall become a party to this Agreement by delivering to the Administrative Agent a Lender Addendum duly executed by such Lender.

10.18. WAIVERS OF JURY TRIAL. THE BORROWER, THE AGENTS AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.
