AMOUNT AND TERMS OF THE COMMITMENTS

Subject to and upon the terms and conditions herein set forth, the Lenders hereby establish in favor of the Borrower a revolving credit facility pursuant to which each Lender severally agrees (to the extent of such Lender’s Commitment) to make Loans to the Borrower in accordance with Section 2.2.

Section 2.2. Loans. Subject to the terms and conditions set forth herein, each Lender severally agrees to make Loans, ratably in proportion to its Pro Rata Share, to the Borrower, from time to time during the Availability Period, in an aggregate principal amount outstanding at any time that will not result in (a) such Lender’s Credit Exposure exceeding such Lender’s Commitment or (b) the sum of the aggregate Credit Exposures of all Lenders exceeding the Aggregate Commitment Amount. During the Availability Period, the Borrower shall be entitled to borrow, prepay and reborrow Loans in accordance with the terms and conditions of this Agreement; provided, that the Borrower may not borrow or reborrow should there exist a Default or Event of Default.

Section 2.3. Procedure for Borrowings. The Borrower shall give the Administrative Agent written notice (or telephonic notice promptly confirmed in writing) of each Borrowing substantially in the form of Exhibit 2.3 (a “Notice of Borrowing”) (x) prior to 11:00 a.m. (New York time) one (1) Business Day prior to the requested date of each Base Rate Borrowing and (y) prior to 11:00 a.m. (New York time) three (3) Business Days prior to the requested date of each Eurodollar Borrowing. Each Notice of Borrowing shall be irrevocable and shall specify: (i) the aggregate principal amount of such Borrowing, (ii) the date of such Borrowing (which shall be a Business Day), (iii) the Type of such Loan comprising such Borrowing and (iv) in the case of a Eurodollar Borrowing, the duration of the initial Interest Period applicable thereto (subject to the provisions of the definition of Interest Period). Each Borrowing shall consist entirely of Base Rate Loans or Eurodollar Loans, as the Borrower may request. The aggregate principal amount of each Eurodollar Borrowing shall be not less than $5,000,000 or a larger multiple of $1,000,000, and the aggregate principal amount of each Base Rate Borrowing shall not be less than $1,000,000 or a larger multiple of $100,000; provided, that Base Rate Loans made pursuant to Section 2.4 may be made in lesser amounts as provided therein. At no time shall the total number of Eurodollar Borrowings outstanding exceed six. Promptly following the receipt of a Notice of Borrowing in accordance herewith, the Administrative Agent shall advise each Lender of the details thereof and the amount of such Lender’s Loan to be made as part of the requested Borrowing.

Section 2.4. Funding of Borrowings.

(a) Each Lender will make available each Loan to be made by it hereunder on the proposed date thereof by wire transfer in immediately available funds by 11:00 a.m. (New York time) to the Administrative Agent at the Payment Office. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts that it receives, in like funds by the close of business on such proposed date, to an account maintained by the Borrower with the Administrative Agent or at the Borrower’s option, by effecting a wire transfer of such amounts to an account designated by the Borrower to the Administrative Agent.

(b) Unless the Administrative Agent shall have been notified by any Lender prior to 5:00 p.m. (New York time) one (1) Business Day prior to the date of a Borrowing in which such Lender is to participate that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date, and the Administrative Agent, in reliance on such assumption, may make available to the Borrower on such date a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender on the date of such Borrowing, the Administrative Agent shall be entitled to recover such corresponding amount on demand from such Lender together with interest at the Federal Funds Rate until the second Business Day after such demand and thereafter at the Base Rate. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent

shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative Agent together with interest at the rate specified for such Borrowing. Nothing in this subsection shall be deemed to relieve any Lender from its obligation to fund its Pro Rata Share of any Borrowing hereunder or to prejudice any rights which the Borrower may have against any Lender as a result of any default by such Lender hereunder.

(c) All Borrowings shall be made by the Lenders on the basis of their respective Pro Rata Shares. No Lender shall be responsible for any default by any other Lender in its obligations hereunder, and each Lender shall be obligated to make its Loans provided to be made by it hereunder, regardless of the failure of any other Lender to make its Loans hereunder.

Section 2.5. Interest Elections.

(a) Each Borrowing initially shall be of the Type specified in the applicable Notice of Borrowing, and in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Notice of Borrowing. Thereafter, the Borrower may elect to convert such Borrowing into a different Type or to continue such Borrowing, and in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section 2.5. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) To make an election pursuant to this Section 2.5, the Borrower shall give the Administrative Agent prior written notice (or telephonic notice promptly confirmed in writing) of each Borrowing substantially in the form of Exhibit 2.5 attached hereto (a “Notice of Conversion/Continuation”) that is to be converted or continued, as the case may be, (x) prior to 10:00 a.m. (New York time) one (1) Business Day prior to the requested date of a conversion into a Base Rate Borrowing and (y) prior to 11:00 a.m. (New York time) three (3) Business Days prior to a continuation of or conversion into a Eurodollar Borrowing. Each such Notice of Conversion/Continuation shall be irrevocable and shall specify (i) the Borrowing to which such Notice of Continuation/Conversion applies and if different options are being elected with respect to different portions thereof, the portions thereof that are to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) shall be specified for each resulting Borrowing); (ii) the effective date of the election made pursuant to such Notice of Continuation/Conversion, which shall be a Business Day, (iii) whether the resulting Borrowing is to be a Base Rate Borrowing or a Eurodollar Borrowing; and (iv) if the resulting Borrowing is to be a Eurodollar Borrowing, the Interest Period applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of “Interest Period”. If any such Notice of Continuation/Conversion requests a Eurodollar Borrowing but does not specify an Interest Period, the Borrower shall be deemed to have selected an Interest Period of one month. The principal amount of any resulting Borrowing shall satisfy the minimum borrowing amount for Eurodollar Borrowings and Base Rate Borrowings set forth in Section 2.3.

(c) If, on the expiration of any Interest Period in respect of any Eurodollar Borrowing, the Borrower shall have failed to deliver a Notice of Conversion/ Continuation, then, unless such Borrowing is repaid as provided herein, the Borrower shall be deemed to have elected to convert such Borrowing to a Base Rate Borrowing. No Borrowing may be converted into, or continued as, a Eurodollar Borrowing if a Default or an Event of Default exists, unless the Administrative Agent and each of the Lenders shall have otherwise consented in writing. No conversion of any Eurodollar Loans shall be permitted except on the last day of the Interest Period in respect thereof.

(d) Upon receipt of any Notice of Conversion/Continuation, the Administrative Agent shall promptly notify each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(a) Unless previously terminated, all Commitments shall terminate on the Commitment Termination Date.

(b) Upon at least three (3) Business Days’ prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent (which notice shall be irrevocable), the Borrower may reduce the Aggregate Commitments in part or terminate the Aggregate Commitments in whole; provided, that (i) any partial reduction shall apply to reduce proportionately and permanently the Commitment of each Lender, (ii) any partial reduction pursuant to this Section 2.6 shall be in an amount of at least $5,000,000 and any larger multiple of $1,000,000, and (iii) no such reduction shall be permitted which would reduce the Aggregate Commitment Amount to an amount less than the outstanding Credit Exposures of all Lenders.

Section 2.7. Repayment of Loans. The outstanding principal amount of all Loans shall be due and payable (together with accrued and unpaid interest thereon) on the Commitment Termination Date.

Section 2.8. Evidence of Indebtedness. Each Lender shall maintain in accordance with its usual practice appropriate records evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable thereon and paid to such Lender from time to time under this Agreement. The Administrative Agent shall maintain appropriate records in which shall be recorded (i) the Commitment of each Lender, (ii) the amount of each Loan made hereunder by each Lender, the Type thereof and the Interest Period applicable thereto, (iii) the date of each continuation thereof pursuant to Section 2.5, (iv) the date of each conversion of all or a portion thereof to another Type pursuant to Section 2.5, (v) the date and amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder in respect of such Loans and (vi) both the date and amount of any sum received by the Administrative Agent hereunder from the Borrower in respect of the Loans and each Lender’s Pro Rata Share thereof. The entries made in such records shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded;

provided, that the failure or delay of any Lender or the Administrative Agent in maintaining or making entries into any such record or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans (both principal and unpaid accrued interest) of such Lender in accordance with the terms of this Agreement.

(a) At the request of any Lender at any time, the Borrower agrees that it will execute and deliver to such Lender a Note payable to the order of such Lender.

Section 2.9. Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing, in whole or in part, without premium or penalty, by giving irrevocable written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent no later than (i) in the case of prepayment of any Eurodollar Borrowing, 11:00 a.m. (New York time) not less than three (3) Business Days prior to any such prepayment, and (ii) in the case of any prepayment of any Base Rate Borrowing, not less than one Business Day prior to the date of such prepayment. Each such notice shall be irrevocable and shall specify the proposed date of such prepayment and the principal amount of each Borrowing or portion thereof to be prepaid. Upon receipt of any such notice, the Administrative Agent shall promptly notify each affected Lender of the contents thereof and of such Lender’s Pro Rata Share of any such prepayment. If such notice is given, the aggregate amount specified in such notice shall be due and payable on the date designated in such notice, together with accrued interest to such date on the amount so prepaid in accordance with Section 2.10(c); provided, that if a Eurodollar Borrowing is prepaid on a date other than the last day of an Interest Period applicable thereto, the Borrower shall also pay all amounts required pursuant to Section 2.16. Each partial prepayment of any Loan shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type pursuant to Section 2.3. Each prepayment of a Borrowing shall be applied ratably to the Loans comprising such Borrowing.

Section 2.10. Interest on Loans.

(a) The Borrower shall pay interest on each Base Rate Loan at the Base Rate in effect from time to time and on each Eurodollar Loan at the Adjusted LIBO Rate for the applicable Interest Period in effect for such Loan, plus, in each case, the Applicable Margin in effect from time to time.

(b) Upon the occurrence, and during the continuation, of an Event of Default under Section 7.1(a) or, at the option of the Required Lenders, any other Event of Default, the Borrower shall pay interest (“Default Interest”) with respect to all Eurodollar Loans at the rate otherwise applicable for the then-current Interest Period plus an additional 2% per annum until the last day of such Interest Period, and thereafter, and with respect to all Base Rate Loans and all other Obligations hereunder (other than Loans), at an all-in rate in effect for Base Rate Loans, plus an additional 2% per annum.

(c) Interest on the principal amount of all Loans shall accrue from and including the date such Loans are made to but excluding the date of any repayment thereof. Interest on all outstanding Base Rate Loans shall be payable quarterly in arrears on the last day of each

March, June, September and December and on the Commitment Termination Date. Interest on all outstanding Eurodollar Loans shall be payable on the last day of each Interest Period applicable thereto, and, in the case of any Eurodollar Loans having an Interest Period in excess of three months, on each day which occurs every three months after the initial date of such Interest Period, and on the Commitment Termination Date. Interest on any Loan which is converted into a Loan of another Type or which is repaid or prepaid shall be payable on the date of such conversion or on the date of any such repayment or prepayment (on the amount repaid or prepaid) thereof. All Default Interest shall be payable on demand.

(d) The Administrative Agent shall determine each interest rate applicable to the Loans hereunder and shall promptly notify the Borrower and the Lenders of such rate in writing (or by telephone, promptly confirmed in writing). Any such determination shall be conclusive and binding for all purposes, absent manifest error.

Section 2.11. Fees.

(a) The Borrower shall pay to the Administrative Agent for its own account fees in the amounts and at the times previously agreed upon in writing by the Borrower and the Administrative Agent.

(b) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee (the “Commitment Fee”), which shall accrue at the Applicable Commitment Fee Percentage per annum (determined daily in accordance with Schedule I) on the daily amount of the unused Commitment of such Lender during the Availability Period.

(c) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a utilization fee (the “Utilization Fee”), which shall accrue at the Applicable Utilization Fee Percentage per annum (determined daily in accordance with Schedule I) on the daily amount of the Loans of such Lender during the Availability Period, but only to the extent on any day that the principal amount of the outstanding Loans is equal to or greater than fifty percent (50%) of the Aggregate Commitments; provided that if on the Commitment Termination Date the outstanding Loans are equal to or greater than fifty percent (50%) of the Aggregate Commitments, then such Utilization Fee shall continue to accrue on the daily amount of the outstanding Loans from and including the Commitment Termination Date to but excluding the date on which no Loans are outstanding.

(d) The Borrower shall pay to the Administrative Agent, for the ratable benefit of each Lender, the upfront fees previously agreed upon by the Borrower and the Administrative Agent, which shall be due and payable on the Closing Date.

(e) Accrued fees under paragraph (b) and (c) above shall be payable quarterly in arrears on the last day of each March, June, September and December, commencing on December 31, 2006 and on the Commitment Termination Date. Utilization Fees that accrue after the Commitment Termination Date shall be payable on demand.

Section 2.12. Computation of Interest and Fees. All computations of interest and fees hereunder shall be made on the basis of a year of 360 days for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable (to the extent computed on the basis of days elapsed). Each determination by the Administrative Agent of an interest amount or fee hereunder shall be made in good faith and, except for manifest error, shall be final, conclusive and binding for all purposes.

Section 2.13. Inability to Determine Interest Rates. If prior to the commencement of any Interest Period for any Eurodollar Borrowing,

(i) the Administrative Agent shall have determined in good faith (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant interbank market, adequate means do not exist for ascertaining LIBOR for such Interest Period, or

(ii) the Administrative Agent shall have received notice from the Required Lenders that the Adjusted LIBO Rate does not adequately and fairly reflect the cost to such Lenders of making, funding or maintaining their Eurodollar Loans for such Interest Period,

the Administrative Agent shall give written notice (or telephonic notice, promptly confirmed in writing) to the Borrower and to the Lenders as soon as practicable thereafter. Until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) the obligations of the Lenders to make Eurodollar Loans or to continue or convert outstanding Loans as or into Eurodollar Loans shall be suspended and (ii) all such affected Loans shall be converted into Base Rate Loans on the last day of the then current Interest Period applicable thereto unless the Borrower prepays such Loans in accordance with this Agreement. Unless the Borrower notifies the Administrative Agent at least one Business Day before the date of any Eurodollar Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, then such Borrowing shall be made as a Base Rate Borrowing.

Section 2.14. Illegality. If any Change in Law shall make it unlawful or impossible for any Lender to make, maintain or fund any Eurodollar Loan and such Lender shall so notify the Administrative Agent, the Administrative Agent shall promptly give notice thereof to the Borrower and the other Lenders, whereupon until such Lender notifies the Administrative Agent and the Borrower that the circumstances giving rise to such suspension no longer exist, the obligation of such Lender to make Eurodollar Loans, or to continue or convert outstanding Loans as or into Eurodollar Loans, shall be suspended. In the case of the making of a Eurodollar Borrowing, such Lender’s Loan shall be made as a Base Rate Loan as part of the same Borrowing for the same Interest Period and if the affected Eurodollar Loan is then outstanding, such Loan shall be converted to a Base Rate Loan either (i) on the last day of the then current Interest Period applicable to such Eurodollar Loan if such Lender may lawfully continue to maintain such Loan to such date or (ii) immediately if such Lender shall determine that it may not lawfully continue to maintain such Eurodollar Loan to such date. Notwithstanding the

foregoing, the affected Lender shall, prior to giving such notice to the Administrative Agent, designate a different Applicable Lending Office if such designation would avoid the need for giving such notice and if such designation would not otherwise be disadvantageous to such Lender in the good faith exercise of its discretion.

Section 2.15. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement that is not otherwise included in the determination of the Adjusted LIBO Rate hereunder against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or

(ii) impose on any Lender or the eurodollar interbank market any other condition affecting this Agreement or any Eurodollar Loans made by such Lender;

and the result of either of the foregoing is to increase the cost to such Lender of making, converting into, continuing or maintaining a Eurodollar Loan or to reduce the amount received or receivable by such Lender hereunder (whether of principal, interest or any other amount), then the Borrower shall promptly pay, upon written notice from and demand by such Lender on the Borrower (with a copy of such notice and demand to the Administrative Agent), to the Administrative Agent for the account of such Lender, within five Business Days after the date of such notice and demand, additional amount or amounts sufficient to compensate such Lender for such additional costs incurred or reduction suffered.

(b) If any Lender shall have determined that on or after the date of this Agreement any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s capital (or on the capital of such Lender’s parent corporation) as a consequence of its obligations hereunder to a level below that which such Lender or such Lender’s parent corporation could have achieved but for such Change in Law (taking into consideration such Lender’s policies or the policies of such Lender’s parent corporation with respect to capital adequacy) then, from time to time, within five (5) Business Days after receipt by the Borrower of written demand by such Lender (with a copy thereof to the Administrative Agent), the Borrower shall pay to such Lender such additional amounts as will compensate such Lender or such Lender’s parent corporation for any such reduction suffered.

(c) A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or such Lender’s parent corporation, as the case may be, specified in paragraph (a) or (b) of this Section 2.15 shall be delivered to the Borrower (with a copy to the Administrative Agent) and shall be conclusive, absent manifest error. The Borrower shall pay any such Lender such amount or amounts within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender to demand compensation pursuant to this Section 2.15 shall not constitute a waiver of such Lender’s right to demand such compensation.

Section 2.16. Funding Indemnity. In the event of (a) the payment of any principal of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion or continuation of a Eurodollar Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure by the Borrower to borrow, prepay, convert or continue any Eurodollar Loan on the date specified in any applicable notice (regardless of whether such notice is withdrawn or revoked), then, in any such event, the Borrower shall compensate each Lender, within five (5) Business Days after written demand from such Lender, for any loss, reasonable cost or expense directly attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense shall be deemed to include an amount determined by such Lender to be the excess, if any, of (A) the amount of interest that would have accrued on the principal amount of such Eurodollar Loan if such event had not occurred at the Adjusted LIBO Rate applicable to such Eurodollar Loan for the period from the date of such event to the last day of the then current Interest Period therefor (or in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Eurodollar Loan) over (B) the amount of interest that would accrue on the principal amount of such Eurodollar Loan for the same period if the Adjusted LIBO Rate were set on the date such Eurodollar Loan was prepaid or converted or the date on which the Borrower failed to borrow, convert or continue such Eurodollar Loan. A certificate as to any additional amount payable under this Section 2.16 submitted to the Borrower by any Lender (with a copy to the Administrative Agent) shall be conclusive, absent manifest error.

Section 2.17. Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided, that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.17) the Administrative Agent or any Lender (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) The Borrower shall indemnify the Administrative Agent and each Lender, within five (5) Business Days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to

amounts payable under this Section 2.17) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender, or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the Code or any treaty to which the United States 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, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. Without limiting the generality of the foregoing, each Foreign Lender agrees that it will deliver to the Administrative Agent and the Borrower (or in the case of a Participant, to the Lender from which the related participation shall have been purchased), as appropriate, two (2) duly completed copies of (i) Internal Revenue Service Form W-8 ECI, or any successor form thereto, certifying that the payments received from the Borrower hereunder are effectively connected with such Foreign Lender’s conduct of a trade or business in the United States; or (ii) Internal Revenue Service Form W-8 BEN, or any successor form thereto, certifying that such Foreign Lender is entitled to benefits under an income tax treaty to which the United States is a party which reduces the rate of withholding tax on payments of interest; or (iii) Internal Revenue Service Form W-8 BEN, or any successor form prescribed by the Internal Revenue Service, together with a certificate (A) establishing that the payment to the Foreign Lender qualifies as “portfolio interest” exempt from U.S. withholding tax under Code section 871(h) or 881(c), and (B) stating that (1) the Foreign Lender is not a bank for purposes of Code section 881(c)(3)(A), or the obligation of the Borrower hereunder is not, with respect to such Foreign Lender, a loan agreement entered into in the ordinary course of its trade or business, within the meaning of that section; (2) the Foreign Lender is not a 10% shareholder of the Borrower within the meaning of Code section 871(h)(3) or 881(c)(3)(B); and (3) the Foreign Lender is not a controlled foreign corporation that is related to the Borrower within the meaning of Code section 881(c)(3)(C); or (iv) such other Internal Revenue Service forms as may be applicable to the Foreign Lender, including Forms W-8 IMY or W-8 EXP. Each such Foreign Lender shall deliver to the Borrower and the Administrative Agent such forms on or before the date that it becomes a party to this Agreement (or in the case of a Participant, on or before the date such Participant purchases the related participation). In addition, each such Foreign Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Foreign Lender. Each such Foreign Lender shall promptly notify the Borrower and the Administrative Agent at any time that 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 Internal Revenue Service for such purpose).

Section 2.18. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees, or amounts payable under Sections 2.15, 2.16 or 2.17, or otherwise) prior to 12:00 noon (New York time) on the date when due, in immediately available funds, free and clear of any defenses, rights of set-off, counterclaim, or withholding or deduction of taxes. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at the Payment Office, except that payments pursuant to Sections 2.15, 2.16 and 2.17 and 9.3 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be made payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, interest and fees then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal then due to such parties.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans that would result in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans; provided, that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under

applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders the amount or amounts due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.4(b), 2.18(d), or 9.3(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid.

Section 2.19. Increase of Commitments; Additional Lenders.

(a) So long as no Event of Default has occurred and is continuing, from time to time after the Closing Date and provided that the Borrower shall have received all consents, approvals, authorizations, registrations and filings and orders required or advisable to be made or obtained under any Requirement of Law, or by any Contractual Obligation of Borrower, Borrower may, upon at least 30 days’ written notice to the Administrative Agent (who shall promptly provide a copy of such notice to each Lender), propose to increase the Aggregate Commitments by an aggregate amount not to exceed $300,000,000 (the amount of any such increase, the “Additional Commitment Amount”). Each Lender shall have the right, for a period of 20 days following receipt of such notice, to elect by written notice to the Borrower and the Administrative Agent to increase its Commitment by a principal amount equal to its Pro Rata Share of the Additional Commitment Amount. No Lender (or any successor thereto) shall have any obligation to increase its Commitment or its other obligations under this Agreement and the other Credit Documents, and any decision by a Lender to increase its Commitment shall be made in its sole discretion independently from any other Lender.

(b) If any Lender shall not elect to increase its Commitment pursuant to subsection (a) of this Section 2.19, the Borrower may designate another bank or other financial institution (which may be, but need not be, one or more of the existing Lenders) which at the time agrees to, in the case of any such Person that is an existing Lender, increase its

Commitment and in the case of any other such Person (an “Additional Lender”), become a party to this Agreement; provided, however, that any new bank or financial institution must be acceptable to the Administrative Agent, which acceptance will not be unreasonably withheld or delayed. The sum of the increases in the Commitments of the existing Lenders pursuant to this subsection (b) plus the Commitments of the Additional Lenders shall not in the aggregate exceed the Additional Commitment Amount.

(c) An increase in the Aggregate Commitment Amount pursuant to this Section 2.19 shall become effective upon the receipt by the Administrative Agent of a supplement or joinder in form and substance reasonably satisfactory to the Administrative Agent executed by the Borrower and by each Additional Lender and by each existing Lender whose Commitment is to be increased, setting forth the new Commitments of such Lenders and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof, together with Notes evidencing such increase in the Commitments, and such evidence of appropriate corporate authorization on the part of the Borrower with respect to the increase in the Commitments and such opinions of counsel for the Borrower with respect to the increase in the Commitments as the Administrative Agent may reasonably request.

(d) Upon the acceptance of any such agreement by the Administrative Agent, the Aggregate Commitment Amount shall automatically be increased by the amount of the Commitments added or increased through such agreement and Schedule II shall automatically be deemed amended to reflect the Commitments of all Lenders after giving effect to the addition and increase of such Commitments.

(e) Upon any increase in the Aggregate Commitment Amount pursuant to this Section 2.19 that is not pro rata among all Lenders, within five Business Days, in the case of any Base Rate Loans then outstanding, and at the end of the then current Interest Period with respect thereto, in the case of any Eurodollar Loans then outstanding, the Borrower shall prepay such Loans in their entirety and, to the extent the Borrower elects to do so and subject to the conditions specified in Article III, the Borrower shall reborrow Loans from the Lenders in proportion to their respective Commitments after giving effect to such increase, until such time as all outstanding Loans are held by the Lenders in proportion to their respective Commitments after giving effect to such increase.

Section 2.20. Mitigation of Obligations. If any Lender requests compensation under Section 2.15, Section 2.16, or Section 2.17, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.17, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the sole judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable under Section 2.15 or Section 2.17, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with such designation or assignment.

Section 2.21. Replacement of Lenders. If any Lender requests compensation under Section 2.15, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority of the account of any Lender pursuant to Section 2.17, or if any Lender defaults in its obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions set forth in Section 9.4(b) all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender); provided, that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal amount of all Loans owed to it, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (in the case of such outstanding principal and accrued interest) and from the Borrower (in the case of all other amounts) and (iii) in the case of a claim for compensation under Section 2.15 or payments required to be made pursuant to Section 2.17, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 2.22. Extension of Commitment Termination Date.

(a) No earlier than 60 days and at least 45 days prior to each of the first and second anniversary of the Closing Date, the Borrower may, by written notice to the Administrative Agent (who shall promptly notify each Lender thereof), request that the Commitment Termination Date then in effect be extended for a one-year period; provided that no extension may be requested unless the Borrower shall have received all consents, approvals, authorizations, registrations and filings and orders required or advisable to be made or obtained under any Requirement of Law, or by any Contractual Obligation of Borrower.

(b) If a Lender agrees, in its individual and sole discretion, to so extend its Commitment (an “Extending Lender”), it shall deliver to the Administrative Agent a written notice of its agreement to do so at least 30 days prior to such anniversary date and the Administrative Agent shall promptly thereafter notify the Borrower of such Extending Lender’s agreement to extend its Commitment (and such agreement shall be irrevocable until such anniversary date). The Commitment of any Lender that fails to accept or respond to the Borrower’s request for extension of the Commitment Termination Date (a “Declining Lender”) shall be terminated on the Commitment Termination Date then in effect for such Lender (without regard to any extension by other Lenders). The Administrative Agent shall promptly notify the Borrower and each Extending Lender of the aggregate Commitments of the Declining Lenders. Each Extending Lender may offer to increase its respective Commitment by an aggregate amount up to the aggregate amount of the Declining Lenders’ Commitments and such Extending Lender shall deliver to the Administrative Agent a notice of its offer to so increase its Commitment no later than 15 days prior to such anniversary date (and such offer shall be irrevocable until such anniversary date).

(c) The Borrower shall have the right to require any Declining Lender to (and any such Declining Lender shall) assign in full its rights and obligations under this Agreement to one or more banks or other financial institutions (which may be, but need not be, one or more of the existing Lenders) which at the time agree to, in the case of any such Person that is an existing Lender, increase and extend its Commitment, and in the case of any other such Person (a “Replacement Lender”), become a party to this Agreement, provided that (i) such assignment is otherwise in compliance with Section 9.4, (ii) such Declining Lender receives payment in full of the unpaid principal amount of all Loans owing to such Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts then due to such Declining Lender under this Agreement and (iii) any such assignment shall be effective on the date on or before such first or second anniversary date as may be specified by the Borrower and agreed to by the Replacement Lenders or the Extending Lenders, as the case may be, and the Administrative Agent.

(d) On the Commitment Termination Date applicable to each Declining Lender, the Borrower shall pay in full the unpaid principal amount of all Loans owing to such Declining Lender, together with all accrued and unpaid interest thereon and all fees accrued and unpaid under this Agreement to the date of such payment of principal and all other amounts then due to such Declining Lender under this Agreement.

(e) Notwithstanding the foregoing, if, but only if, Extending Lenders and Replacement Lenders have agreed to provide and extend Commitments in an aggregate amount greater than 50% of the aggregate amount of the Commitments outstanding immediately prior to such anniversary date, the Commitment Termination Date of such Extending Lenders and Replacement Lenders shall be extended by one year.

consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official of such Person or any substantial part of its property or make any general assignment for the benefit of creditors; or (iv) the Borrower or any of its Material Subsidiaries shall admit in writing its inability to pay its debts generally as they become due or any action shall be taken by such Person in furtherance of any of the aforesaid purposes.

(f) Defaults under Other Agreements. With respect to any indebtedness of the Borrower in excess of $100,000,000 (other than indebtedness outstanding under this Agreement or Non-Recourse Indebtedness) (A) the Borrower shall (1) default in any payment (beyond the applicable grace period with respect thereto, if any) with respect to any such indebtedness, or (2) default (after giving effect to any applicable grace period) in the observance or performance of any covenant or agreement relating to such indebtedness or contained in any instrument or agreement evidencing, securing or relating thereto, or any other event or condition shall occur or condition exist, the effect of which default or other event or condition is to cause, or permit, the holder of the holders of such indebtedness (or trustee or agent on behalf of such holders) to cause (determined without regard to whether any notice or lapse of time is required) any such indebtedness to become due prior to its stated maturity; or (B) any such indebtedness shall be declared due and payable, or required to be prepaid other than by a regularly scheduled required prepayment, or by a mandatory prepayment upon specified events or conditions, in each case, prior to the stated maturity thereof; or (C) any such indebtedness shall mature and remain unpaid.

(g) Judgments. One or more final judgments, orders, or decrees shall be entered against the Borrower involving a liability of $100,000,000 or more, in the aggregate (to the extent not paid or covered by insurance provided by a carrier who has acknowledged coverage) and such judgments, orders or decrees shall continue unsatisfied, undischarged and unstayed for a period of 90 days; provided that if such judgment, order or decree provides for periodic payments over time then the Borrower shall have a grace period of 30 days with respect to each such periodic payment.

(h) ERISA. The occurrence of any of the following events or conditions if any of the same would be reasonably expected to result in a liability of an amount greater than or equal to $20,000,000: (A) any “accumulated funding deficiency,” as such term is defined in Section 302 of ERISA and Section 412 of the Code, whether or not waived, shall exist with respect to any Plan, or any lien shall arise on the assets of the Borrower or any ERISA Affiliate in favor of the PBGC or a Plan; (B) a Termination Event shall occur with respect to a Single Employer Plan, which is, in the reasonable opinion of the Administrative Agent, likely to result in the termination of such Plan for purposes of Title IV of ERISA; (C) a Termination Event shall occur with respect to a Multiemployer Plan or Multiple Employer Plan, which is, in the reasonable opinion of the Administrative Agent, likely to result in (i) the termination of such Plan for purposes of Title IV of ERISA, or (ii) the Borrower or any ERISA Affiliate incurring any liability in connection with a withdrawal from, reorganization of (within the meaning of Section 4241 of ERISA), or insolvency (within the meaning of Section 4245 of ERISA) of such Plan; or (D) any prohibited transaction (within the meaning of Section 406 of ERISA or Section 4975 of the Code) or breach of fiduciary responsibility shall occur which would be reasonably

expected to subject the Borrower or any ERISA Affiliate to any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Code, or under any agreement or other instrument pursuant to which the Borrower or any ERISA Affiliate has agreed or is required to indemnify any person against any such liability.

(i) Change of Control. The occurrence of any Change of Control.

Section 7.2. Acceleration; Remedies. Upon the occurrence and during the continuation of an Event of Default, the Administrative Agent may, with the consent of the Required Lenders, and shall, upon the request and direction of the Required Lenders, by written notice to the Borrower take any of the following actions without prejudice to the rights of the Administrative Agent or any Lender to enforce its claims against the Borrower, except as otherwise specifically provided for herein:

(a) Termination of Commitments. Declare the Commitments terminated whereupon the Commitments shall be immediately terminated.

(b) Acceleration of Loans. Declare the unpaid amount of all Borrower Obligations to be due whereupon the same shall be immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower.

(c) Enforcement of Rights. Enforce any and all rights and interests created and existing under the Credit Documents or otherwise available at law or in equity, including, without limitation, all rights of set-off.

Notwithstanding the foregoing, if an Event of Default specified in Section 7.1(e) shall occur, then the Commitments shall automatically terminate and all Loans, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Lenders and the Administrative Agent hereunder shall immediately become due and payable without the giving of any notice or other action by the Administrative Agent or the Lenders.

Notwithstanding the fact that enforcement powers reside primarily with the Administrative Agent, each Lender has, to the extent permitted by law, a separate right of payment and shall be considered a separate “creditor” holding a separate “claim” within the meaning of Section 101(5) of the Bankruptcy Code or any other insolvency statute.

Section 7.3. Allocation of Payments After Event of Default.

Notwithstanding any other provisions of this Agreement, after the occurrence of an Event of Default, all amounts collected or received by the Administrative Agent or any Lender on account of amounts outstanding under any of the Credit Documents shall be paid over or delivered as follows:

FIRST, to the payment of all reasonable out-of-pocket costs and expenses (including without limitation reasonable attorneys’ fees) of the Administrative Agent or any of the Lenders in connection with enforcing the rights of the Lenders under the Credit Documents, pro rata as set forth below;

SECOND, to payment of any fees owed to the Administrative Agent or any Lender, pro rata as set forth below;

THIRD, to the payment of all accrued interest payable to the Lenders hereunder, pro rata as set forth below;

FOURTH, to the payment of the outstanding principal amount of the Loans, pro rata as set forth below;

FIFTH, to all other obligations which shall have become due and payable under the Credit Documents and not repaid pursuant to clauses “FIRST” through “FOURTH” above; and

SIXTH, to the payment of the surplus, if any, to whoever may be lawfully entitled to receive such surplus.

In carrying out the foregoing, (a) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category and (b) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the then outstanding Loans held by such Lender bears to the aggregate then outstanding Loans) of amounts available to be applied.

ARTICLE VIII

THE ADMINISTRATIVE AGENT

Section 8.1. Appointment of Administrative Agent. Each Lender irrevocably appoints SunTrust Bank as the Administrative Agent and authorizes it to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent under this Agreement and the other Credit Documents, together with all such actions and powers that are reasonably incidental thereto. The Administrative Agent may perform any of its duties hereunder or under the other Credit Documents by or through any one or more sub-agents or attorneys-in-fact appointed by the Administrative Agent. The Administrative Agent and any such sub-agent or attorney-in-fact may perform any and all of its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions set forth in this Article shall apply to any such sub-agent or attorney-in-fact and the Related Parties of the Administrative Agent, any such sub-agent and any such attorney-in-fact and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Section 8.2. Nature of Duties of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in this Agreement and the other Credit Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except those discretionary rights and powers expressly contemplated by the Credit Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.2), and (c) except as expressly set forth in the Credit Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Subsidiaries that is communicated to or obtained by the Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it, its sub-agents or attorneys-in-fact with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.2) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall not be responsible for the negligence or misconduct of any sub-agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall not be deemed to have knowledge of any Default or Event of Default unless and until written notice thereof (which notice shall include an express reference to such event being a “Default” or “Event of Default” hereunder) is given to the Administrative Agent by the Borrower or any Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Credit Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements, or other terms and conditions set forth in any Credit Document, (iv) the validity, enforceability, effectiveness or genuineness of any Credit Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article III or elsewhere in any Credit Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. The Administrative Agent may consult with legal counsel (including counsel for the Borrower) concerning all matters pertaining to such duties.

Section 8.3. Lack of Reliance on the Administrative Agent. Each of the Lenders acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each of the Lenders also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, continue to make its own decisions in taking or not taking of any action under or based on this Agreement, any related agreement or any document furnished hereunder or thereunder.

Section 8.4. Certain Rights of the Administrative Agent. If the Administrative Agent shall request instructions from the Required Lenders with respect to any

action or actions (including the failure to act) in connection with this Agreement, the Administrative Agent shall be entitled to refrain from such act or taking such act, unless and until it shall have received instructions from such Lenders; and the Administrative Agent shall not incur liability to any Person by reason of so refraining. Without limiting the foregoing, no Lender shall have any right of action whatsoever against the Administrative Agent as a result of the Administrative Agent acting or refraining from acting hereunder in accordance with the instructions of the Required Lenders where required by the terms of this Agreement.

Section 8.5. Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed, sent or made by the proper Person. The Administrative Agent may also rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or not taken by it in accordance with the advice of such counsel, accountants or experts.

Section 8.6. The Administrative Agent in its Individual Capacity. The bank serving as the Administrative Agent shall have the same rights and powers under this Agreement and any other Credit Document in its capacity as a Lender as any other Lender and may exercise or refrain from exercising the same as though it were not the Administrative Agent; and the terms “Lenders”, “Required Lenders”, “holders of Notes”, or any similar terms shall, unless the context clearly otherwise indicates, include the Administrative Agent in its individual capacity. The bank acting as the Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Borrower or any Subsidiary or Affiliate of the Borrower as if it were not the Administrative Agent hereunder.

Section 8.7. Successor Administrative Agent.

(a) The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent, subject to the approval by the Borrower provided that no Default or Event of Default shall exist at such time. If no successor Administrative Agent shall have been so appointed, and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of resignation, then the retiring Administrative Agent may, on behalf of the Lenders, appoint a successor Administrative Agent, which shall be a commercial bank organized under the laws of the United States of America or any state thereof or a bank which maintains an office in the United States, having a combined capital and surplus of at least $500,000,000.

(b) Upon the acceptance of its appointment as the Administrative Agent hereunder by a successor, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations

under this Agreement and the other Credit Documents. If within 45 days after written notice is given of the retiring Administrative Agent’s resignation under this Section 8.7 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 45^th day (i) the retiring Administrative Agent’s resignation shall become effective, (ii) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Credit Documents and (iii) the Required Lenders shall thereafter perform all duties of the retiring Administrative Agent under the Credit Documents until such time as the Required Lenders appoint a successor Administrative Agent as provided above. After any retiring Administrative Agent’s resignation hereunder, the provisions of this Article shall continue in effect for the benefit of such retiring Administrative Agent and its representatives and agents in respect of any actions taken or not taken by any of them while it was serving as the Administrative Agent.

Section 8.8. Authorization to Execute other Credit Documents. Each Lender hereby authorizes the Administrative Agent to execute on behalf of all Lenders all Credit Documents other than this Agreement.

Section 8.9. Co-Documentation Agents; Syndication Agent. Each of the Lenders and the Borrower hereby acknowledges and agrees that the Co-Documentation Agents and the Syndication Agent shall have no duties or obligations under any Credit Documents to any Lender or the Borrower.

To any other Lender:		the address set forth in the Administrative Questionnaire or the Assignment and Acceptance Agreement executed by such Lender

Notices and other communications hereunder may be delivered or furnished by electronic communication (including e-mail and Internet or intranet websites) pursuant to procedures approved by the Administrative Agent, provided that the foregoing shall not apply to notices to any Lender pursuant to Article II if such Lender has notified the Administrative Agent that it is incapable of receiving notices under such Article by electronic communication. The Administrative Agent or the Borrower may, in its discretion, agree to accept notices and other communications to it hereunder by electronic communications pursuant to procedures approved by it, provided that approval of such procedures may be limited to particular notices or communications. Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested”

function, as available, return e-mail or other written acknowledgement), provided that if such notice or other communication is not sent during the normal business hours of the recipient, such notice or communication shall be deemed to have been sent at the opening of business on the next business day for the recipient, and (ii) notices or communications posted to an Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available and identifying the website address therefor.

Any party hereto may change its address or telecopy number for notices and other communications hereunder by notice to the other parties hereto. All such notices and other communications shall, when transmitted by overnight delivery, or faxed, be effective when delivered for overnight (next-day) delivery, or transmitted in legible form by facsimile machine, respectively, or if mailed, upon the third Business Day after the date deposited into the mail or if delivered, upon delivery; provided, that notices delivered to the Administrative Agent shall not be effective until actually received by such Person at its address specified in this Section 9.1.

(b) Any agreement of the Administrative Agent and the Lenders herein to receive certain notices by telephone or facsimile is solely for the convenience and at the request of the Borrower. The Administrative Agent and the Lenders shall be entitled to rely on the authority of any Person purporting to be a Person authorized by the Borrower to give such notice and the Administrative Agent and Lenders shall not have any liability to the Borrower or other Person on account of any action taken or not taken by the Administrative Agent or the Lenders in reliance upon such telephonic or facsimile notice. The obligation of the Borrower to repay the Loans and all other Obligations hereunder shall not be affected in any way or to any extent by any failure of the Administrative Agent and the Lenders to receive written confirmation of any telephonic or facsimile notice or the receipt by the Administrative Agent and the Lenders of a confirmation which is at variance with the terms understood by the Administrative Agent and the Lenders to be contained in any such telephonic or facsimile notice.

Section 9.2. Waiver; Amendments.

(a) No failure or delay by the Administrative Agent or any Lender in exercising any right or power hereunder or any other Credit Document, and no course of dealing between the Borrower and the Administrative Agent or any Lender, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power or any abandonment or discontinuance of steps to enforce such right or power, preclude any other or further exercise thereof or the exercise of any other right or power hereunder or thereunder. The rights and remedies of the Administrative Agent and the Lenders hereunder and under the other Credit Documents are cumulative and are not exclusive of any rights or remedies provided by law. No waiver of any provision of this Agreement or any other Credit Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 9.2, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan shall not be construed as a waiver of any Default or Event of Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default or Event of Default at the time.

(b) No amendment or waiver of any provision of this Agreement or the other Credit Documents, nor consent to any departure by the Borrower therefrom, shall in any event be effective unless the same shall be in writing and signed by the Borrower and the Required Lenders or the Borrower and the Administrative Agent with the consent of the Required Lenders and then such waiver or consent shall be effective only in the specific instance and for the specific purpose for which given; provided, that no amendment or waiver shall: (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section 9.2 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; (vi) release any guarantor or limit the liability of any such guarantor under any guaranty agreement, without the written consent of each Lender; (vii) release all or substantially all collateral (if any) securing any of the Obligations, without the written consent of each Lender; provided further, that no such agreement shall amend, modify or otherwise affect the rights, duties or obligations of the Administrative Agent without the prior written consent of such Person. Notwithstanding anything contained herein to the contrary, this Agreement may be amended and restated without the consent of any Lender (but with the consent of the Borrower and the Administrative Agent) if, upon giving effect to such amendment and restatement, such Lender shall no longer be a party to this Agreement (as so amended and restated), the Commitments of such Lender shall have terminated (but such Lender shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.3), such Lender shall have no other commitment or other obligation hereunder and shall have been paid in full all principal, interest and other amounts owing to it or accrued for its account under this Agreement.

Section 9.3. Expenses; Indemnification.

(a) The Borrower shall pay (i) all reasonable, out-of-pocket costs and expenses of the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent and its Affiliates, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Credit Documents and any amendments, modifications or waivers thereof (whether or not the transactions contemplated in this Agreement or any other Credit Document shall be consummated), and (ii) all reasonable out-of-pocket costs and expenses (including, without limitation, the reasonable fees, charges and disbursements of outside counsel and the allocated cost of inside counsel) incurred by the Administrative Agent or any Lender in connection with the enforcement or protection of its rights in connection with this Agreement, including its rights under this Section 9.3, or in connection with the Loans made hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans.

(b) The Borrower shall indemnify the Administrative Agent (and any sub-agent thereof), each Lender and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses (including the reasonable fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless each Indemnitee from all fees and time charges and disbursements for attorneys who may be employees of any Indemnitee, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Credit Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan or the use or proposed use of the proceeds therefrom, (iii) any actual or alleged presence or Release of Hazardous Materials on or from any property owned or operated by the Borrower or any of its Subsidiaries, or any Environmental Liability related in any way to the Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory, whether brought by a third party or by the Borrower, and regardless of whether any Indemnitee is a party thereto, provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnitee or (y) result from a claim brought by the Borrower against an Indemnitee for breach in bad faith of such Indemnitee’s obligations hereunder or under any other Credit Document, if the Borrower has obtained a final and nonappealable judgment in its favor on such claim as determined by a court of competent jurisdiction.

(c) The Borrower shall pay, and hold the Administrative Agent and each of the Lenders harmless from and against, any and all present and future stamp, documentary, and other similar taxes with respect to this Agreement and any other Credit Documents, any collateral described therein, or any payments due thereunder, and save the Administrative Agent and each Lender harmless from and against any and all liabilities with respect to or resulting from any delay or omission to pay such taxes.

(d) To the extent that the Borrower fails to pay any amount required to be paid to the Administrative Agent under clauses (a), (b) or (c) hereof, each Lender severally agrees to pay to the Administrative Agent such Lender’s Pro Rata Share (determined as of the time that the unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided, that the unreimbursed expense or indemnified payment, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent in its capacity as such.

(e) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to actual or direct damages) arising out of, in connection with or as a result of, this Agreement or any agreement or instrument contemplated hereby, the transactions contemplated therein, any Loan or the use of proceeds thereof.

(f) All amounts due under this Section 9.3 shall be payable promptly after written demand therefor.

Section 9.4. Successors and Assigns.

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans and Credit Exposure outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans and Credit Exposure of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Acceptance, as of the Trade Date) shall not be less than $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loans, Credit Exposure or the Commitment assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments to a Person that is not a Lender with a Commitment.

(iv) Assignment and Acceptance. The parties to each assignment shall deliver to the Administrative Agent (A) a duly executed Assignment and Acceptance, (B) a processing and recordation fee of $3,500, (C) an Administrative Questionnaire unless the assignee is already a Lender and (D) the documents required under Section 2.17(e) if such assignee is a Foreign Lender.

(v) No Assignment to Borrower. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section 9.4, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.15, 2.16, 2.17 and 9.3 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section 9.4. If the consent of the Borrower to an assignment is required hereunder (including a

consent to an assignment which does not meet the minimum assignment thresholds specified above), the Borrower shall be deemed to have given its consent five Business Days after the date notice thereof has actually been delivered by the assigning Lender (through the Administrative Agent) to the Borrower, unless such consent is expressly refused by the Borrower prior to such fifth Business Day.

(c) The Administrative Agent shall maintain at one of its offices in Atlanta, Georgia a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amount of the Loans and Credit Exposure owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person, the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

(e) Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver with respect to the following to the extent affecting such Participant: (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the date fixed for any payment of any principal of, or interest on, any Loan or interest thereon or any fees hereunder or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date for the termination or reduction of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.18(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section 9.4 or the definition of “Required Lenders” or any other provision hereof specifying the number or percentage of Lenders which are required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the consent of each Lender; (vi) release any guarantor or limit the liability of

any such guarantor under any guaranty agreement without the written consent of each Lender except to the extent such release is expressly provided under the terms of this Agreement or such guaranty agreement; or (vii) release all or substantially all collateral (if any) securing any of the Obligations. Subject to paragraph (e) of this Section 9.4, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.15, 2.16, and 2.17 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 9.4. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.7 as though it were a Lender, provided such Participant agrees to be subject to Section 2.15 as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 2.15 and Section 2.17 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.17 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.17(e) as though it were a Lender.

(g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 9.5. Governing Law; Jurisdiction; Consent to Service of Process.

(a) This Agreement and the other Credit Documents shall be construed in accordance with and be governed by the law (without giving effect to the conflict of law principles thereof, except for Sections 5-1401 and 5-1402 of the New York General Obligations Law) of the State of New York.

(b) The Borrower hereby irrevocably and unconditionally submits, for itself and its property, to the exclusive jurisdiction of the United States District Court of the Southern District of New York, and of any state court of the State of New York sitting in New York county and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Credit Document or the transactions contemplated hereby or thereby, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York state court or, to the extent permitted by applicable law, such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Credit Document shall affect any right that the Administrative Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or any other Credit Document against the Borrower or its properties in the courts of any jurisdiction.

(c) The Borrower irrevocably and unconditionally waives any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding described in paragraph (b) of this Section 9.5 and brought in any court referred to in paragraph (b) of this Section 9.5. Each of the parties hereto irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Each party to this Agreement irrevocably consents to the service of process in the manner provided for notices in Section 9.1, provided that such service of process is delivered only by overnight courier, signature required. Nothing in this Agreement or in any other Credit Document will affect the right of any party hereto to serve process in any other manner permitted by law.

Section 9.6. WAIVER OF JURY TRIAL. EACH PARTY HERETO IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF THIS AGREEMENT OR ANY OTHER CREDIT DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

Section 9.7. Right of Setoff. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender shall have the right, at any time or from time to time upon the occurrence and during the continuance of an Event of Default, without prior notice to the Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, to set off and apply against all deposits (general or special, time or demand, provisional or final) of the Borrower at any time held or other obligations at any time owing by such Lender to or for the credit or the account of the Borrower against any and all Obligations held by such Lender irrespective of whether such Lender shall have made demand hereunder and although such Obligations may be unmatured. Each Lender agrees promptly to notify the Administrative Agent and the Borrower after any such set-off and any application made by such Lender; provided, that the failure to give such notice shall not affect the validity of such set-off and application. Each Lender agrees to apply all amounts collected from any such set-off to the Obligations before applying such amounts to any other Indebtedness or other obligations owed by the Borrower and any of its Subsidiaries to such Lender.

Section 9.8. Counterparts; Integration. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by telecopy), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. This Agreement, the Fee Letter, the other Credit Documents, and any separate letter agreement(s) relating to any fees payable to the Administrative Agent constitute the entire agreement among the parties hereto and thereto regarding the subject matters hereof and thereof and supersede all prior agreements and understandings, oral or written, regarding such subject matters.

Section 9.9. Survival. All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid and so long as the Commitments have not expired or terminated. The provisions of Sections 2.15, 2.16, 2.17, and 9.3 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Commitments or the termination of this Agreement or any provision hereof. All representations and warranties made herein, in the certificates, reports, notices, and other documents delivered pursuant to this Agreement shall survive the execution and delivery of this Agreement and the other Credit Documents, and the making of the Loans.

Section 9.10. Severability. Any provision of this Agreement or any other Credit Document held to be illegal, invalid or unenforceable in any jurisdiction, shall, as to such jurisdiction, be ineffective to the extent of such illegality, invalidity or unenforceability without affecting the legality, validity or enforceability of the remaining provisions hereof or thereof; and the illegality, invalidity or unenforceability of a particular provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

Section 9.11. Confidentiality. Each of the Administrative Agent and each Lender agrees to take normal and reasonable precautions to maintain the confidentiality of any Information, except that such Information may be disclosed (i) to any Related Party of the Administrative Agent or any such Lender, including without limitation accountants, legal counsel and other advisors, (ii) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (iii) to the extent requested by any regulatory agency or authority, (iv) to the extent that such information becomes publicly available other than as a result of a breach of this Section 9.11, or which becomes available to the Administrative Agent,

any Lender or any Related Party of any of the foregoing on a non-confidential basis from a source other than the Borrower, (v) in connection with the exercise of any remedy hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, and vi) subject to provisions substantially similar to this Section 9.11, to any actual or prospective assignee or Participant, or (vii) with the consent of the Borrower. Any Person required to maintain the confidentiality of any information as provided for in this Section 9.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such Person would accord its own confidential information. For the purposes of this Section, “Information” means all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent or any Lender on a nonconfidential basis prior to disclosure by the Borrower; provided that, in the case of information received from the Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential.

Section 9.12. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which may be treated as interest on such Loan under applicable law (collectively, the “Charges”), shall exceed the maximum lawful rate of interest (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by a Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section 9.12 shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment, shall have been received by such Lender.

Section 9.13. Waiver of Effect of Corporate Seal. The Borrower represents and warrants that it is not required to affix its corporate seal to this Agreement or any other Credit Document pursuant to any requirement of law or regulation, agrees that this Agreement is delivered by Borrower under seal and waives any shortening of the statute of limitations that may result from not affixing the corporate seal to this Agreement or such other Credit Documents.

Section 9.14. Patriot Act. The Administrative Agent and each Lender hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act. The Borrower shall, and shall cause each of its Subsidiaries to, provide to the extent commercially reasonable, such information and take such other actions as are reasonably requested by the Administrative Agent or any Lender in order to assist the Administrative Agent and the Lenders in maintaining compliance with the Patriot Act.
