(f) Letters of Credit.

(i) The Borrower, the Existing Issuing Banks and each of the Revolving Credit Lenders hereby agree that each of the Existing Letters of Credit shall, on and after the Closing Date, be deemed for all purposes of this Agreement to be a Letter of Credit issued and outstanding under the terms of this Agreement. Each Issuing Bank agrees, on the terms and conditions hereinafter set forth, to issue letters of credit (the “Letters of Credit”) in U.S. dollars for the account of the Borrower from time to time on any Business Day during the period from the date hereof until five Business Days before the Termination Date (A) in an Available Amount for each such Letter of Credit not to exceed at any time the Unused Revolving Credit Commitment of such Issuing Bank at such time and (B) in an aggregate Available Amount for all Letters of Credit not to exceed the lesser of (1) the Letter of Credit Facility at such time and (2) the aggregate Unused Revolving Credit Commitments at such time. No Letter of Credit shall have an expiration date (including all rights of the Borrower or the beneficiary of such Letter of Credit to require renewal) later than the earlier of (x) five Business Days prior to the Termination Date and (y) one year after the date of issuance thereof, but any such Letter of Credit may by its terms be renewable annually on the terms set forth in clause (ii) of this Section 2.01(f). Within the limits of the Letter of Credit Facility, and subject to the limits referred to above, the Borrower may request the issuance of Letters of Credit under this Section 2.01(f)(i), repay any Letter of Credit Advances resulting from drawings thereunder pursuant to Section 2.03(b) and request the issuance of additional Letters of Credit under this Section 2.01(f)(i).

(ii) Each Letter of Credit may by its terms be renewable annually upon notice (a “Notice of Renewal”) given to the Issuing Bank and the Administrative Agent on or prior to any date for notice of renewal set forth in such Letter of Credit but in any event at least three Business Days prior to the date of the proposed renewal of such Letter

of Credit and upon fulfillment of the applicable conditions set forth in Article III unless such Issuing Bank has notified the Borrower (with a copy to the Administrative Agent) on or prior to the date for notice of termination set forth in such Letter of Credit but in any event at least 30 Business Days prior to the date of automatic renewal of its election not to renew such Letter of Credit (a “Notice of Termination”); provided that the terms of each Letter of Credit that is automatically renewable annually (A) shall require the Issuing Bank to give the beneficiary of such Letter of Credit notice of any Notice of Termination, (B) shall permit such beneficiary, upon receipt of such notice, to draw under such Letter of Credit prior to the date such Letter of Credit otherwise would have been automatically renewed and (C) shall not permit the expiration date (after giving effect to any renewal) of such Letter of Credit in any event to be extended to a date later than five Business Days prior to the Termination Date. If either a Notice of Renewal is not given by the Borrower or a Notice of Termination is given by the Issuing Bank pursuant to the immediately preceding sentence, such Letter of Credit shall expire on the date on which it otherwise would have been automatically renewed; provided, however, that in the absence of receipt of a Notice of Renewal the Issuing Bank may in its discretion, unless instructed to the contrary by the Administrative Agent or the Borrower deem that a Notice of Renewal had been timely delivered and, in such case, a Notice of Renewal shall be deemed to have been so delivered for all purposes under this Agreement.

SECTION 2.02. Making the Advances. (a) Except as otherwise provided in Section 2.02(b) or 2.03 and except that the Term C Borrowing shall be made on the Closing Date, each Borrowing (other than a Swing Line Borrowing) shall be made on notice, given not later than 2:00 P.M. (New York, New York time) on the third Business Day prior to the date of the proposed Borrowing in the case of a Borrowing comprised of Eurodollar Rate Advances, or on the first Business Day prior to the date of the proposed Borrowing in the case of a Borrowing comprised of Base Rate Advances, by the Borrower to the Administrative Agent, which shall give prompt notice thereof to each Appropriate Lender. Each notice of a Borrowing (a “Notice of Borrowing”) shall be by telephone, confirmed immediately in writing, or by telecopier, in substantially the form of Exhibit B-1 hereto, shall be duly executed by a Responsible Officer of the Borrower, and shall specify therein: (i) the requested date of such Borrowing (which shall be a Business Day); (ii) the Facility under which such Borrowing is requested to be made; (iii) the Type of Advances requested to comprise such Borrowing; (iv) the requested aggregate amount of such Borrowing; and (v) in the case of a Borrowing comprised of Eurodollar Rate Advances, the requested duration of the initial Interest Period for each such Advance. Each Appropriate Lender shall, before 2:00 P.M. (New York, New York time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account, in same day funds, such Lender’s Pro Rata Share of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Administrative Agent will make such funds available to the Borrower by crediting the Borrower’s Account; provided, however, that, in the case of any Revolving Credit Borrowing, the Administrative Agent shall first make a portion of such funds equal to the aggregate principal amount of any Swing Line Advances and Letter of Credit Advances made by the Swing Line Bank or the Issuing Bank, as the case may be, and by any Revolving Credit Lender and outstanding on the date of such Revolving Credit Borrowing, plus accrued and unpaid interest thereon to and as of such date, available to the Swing Line Bank or the Issuing Bank, as applicable, and such other Revolving Credit Lenders for repayment of such Swing Line Advances and Letter of Credit Advances.

(b) (i) Each Swing Line Borrowing shall be made on notice, given not later than 2:00 P.M. (New York, New York time) on the date of the proposed Swing Line Borrowing, by the Borrower to the Swing Line Bank and the Administrative Agent. Each notice of a Swing Line Borrowing (a “Notice of Swing Line Borrowing”) shall be by telephone, confirmed immediately

in writing, or telecopier, shall be in substantially the form of Exhibit B-2 hereto and duly executed by a Responsible Officer of the Borrower, and shall specify therein: (A) the requested date of such Borrowing (which shall be a Business Day); (B) the requested amount of such Borrowing; and (C) the requested maturity of such Borrowing (which maturity shall be no later than the seventh day after the requested date of such Borrowing). Upon fulfillment of the applicable conditions set forth in Article III, the Swing Line Bank will make the amount thereof available for the account of its Applicable Lending Office to the Borrower by crediting the Borrower’s Account.

(ii) Upon demand by the Swing Line Bank, with a copy of such demand to the Administrative Agent (which shall give prompt notice thereof to each Revolving Credit Lender), each Revolving Credit Lender shall purchase from the Swing Line Bank, and the Swing Line Bank shall sell and assign to each such Revolving Credit Lender, such Revolving Credit Lender’s Pro Rata Share of such outstanding Swing Line Borrowing as of the date of such demand, by making available for the account of its Applicable Lending Office to the Administrative Agent at the Administrative Agent’s Account for the account of the Swing Line Bank, in same day funds, an amount equal to such Pro Rata Share. Promptly after receipt of such funds, the Administrative Agent shall transfer such funds to the Swing Line Bank at its Applicable Lending Office. Each Revolving Credit Lender hereby agrees to purchase its Pro Rata Share of an outstanding Swing Line Borrowing on (A) the Business Day on which demand therefor is made by the Swing Line Bank so long as notice of such demand is given not later than 12:00 Noon (New York, New York time) on such Business Day or (B) the first Business Day next succeeding such demand if notice of such demand is given after such time. The Borrower hereby agrees to each such sale and assignment. Upon any such assignment by the Swing Line Bank to any Revolving Credit Lender of a portion of a Swing Line Borrowing, the Swing Line Bank represents and warrants to such Revolving Credit Lender that the Swing Line Bank is the legal and beneficial owner of such interest being assigned by it, but makes no other representation or warranty and assumes no responsibility with respect to such Swing Line Borrowing, the Loan Documents or any Loan Party. If and to the extent that any Revolving Credit Lender shall not have so made its Pro Rata Share of any applicable Swing Line Borrowing available to the Administrative Agent in accordance with the foregoing provisions of this Section 2.02(b)(ii), such Revolving Credit Lender hereby agrees to pay to the Administrative Agent forthwith on demand the amount of its Pro Rata Share, together with interest thereon, for each day from the date of demand by the Swing Line Bank therefor until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate. If such Lender shall pay to the Administrative Agent the amount of its Pro Rata Share for the account of the Swing Line Bank on any Business Day, such amount so paid in respect of principal shall constitute a Swing Line Advance made by such Lender on such Business Day for all purposes of this Agreement, and the outstanding principal amount of the Swing Line Advance made by the Swing Line Bank shall be reduced by such amount on such Business Day.

(iii) The obligation of each Revolving Credit Lender to purchase its Pro Rata Share of each outstanding Swing Line Borrowing upon demand by the Swing Line Bank therefor pursuant to clause (ii) of this Section 2.02(b) shall be absolute, unconditional and irrevocable, and shall be made strictly in accordance with the terms of clause (ii) of this Section 2.02(b) under all circumstances, including, without limitation, the following circumstances:

(A) any lack of validity or enforceability of any Loan Document or any other agreement or instrument relating thereto;

(B) the existence of any claim, set-off, defense or other right that such Revolving Credit Lender may have at any time against the Swing Line Bank, the Borrower or any other Person, whether in connection with the transactions contemplated by the Loan Documents or any unrelated transaction;

(D) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(c) Anything in subsection (a) of this Section 2.02 to the contrary notwithstanding, (i) the Borrower may not select Eurodollar Rate Advances if the obligation of the Appropriate Lenders to make Eurodollar Rate Advances shall then be suspended pursuant to Section 2.09 or 2.10. In addition, the Term Advances may not be outstanding as part of more than 10 separate Borrowings and the Revolving Credit Advances may not be outstanding as part of more than 10 separate Borrowings.

(d) Each Notice of Borrowing and Notice of Swing Line Borrowing shall be irrevocable and binding on the Borrower. In the case of any Borrowing that the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrower shall indemnify each Appropriate Lender against any loss, cost or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III, including, without limitation, any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Eurodollar Rate Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date. A certificate of the Lender requesting compensation pursuant to this subsection (d) submitted to the Borrower by such Lender and specifying therein the amount of such additional compensation (including the basis of calculation thereof) shall be conclusive and binding for all purposes, absent manifest error.

(e) Unless the Administrative Agent shall have received notice from an Appropriate Lender prior to the date of any Borrowing under a Facility under which such Lender has a Commitment that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of such Borrowing, the Administrative Agent may assume that such Lender has made the amount of such Pro Rata Share available to the Administrative Agent on the date of such Borrowing in accordance with subsection (a) or (b) of this Section 2.02, as applicable, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made the amount of such Pro Rata Share available to the Administrative Agent, such Lender and the Borrower severally agree to repay or to pay to the Administrative Agent forthwith on demand such corresponding amount, together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid or paid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable at such time under Section 2.07 to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate. If such Lender shall pay to the Administrative Agent such corresponding amount, such amount so paid shall constitute such Lender’s Advance as part of such Borrowing for all purposes under this Agreement.

(f) The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, hereunder to make its Advance on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

SECTION 2.03. Issuance of and Drawings and Reimbursement Under Letters of Credit.

(a) Request for Issuance. Each Letter of Credit shall be issued upon notice, given not later than 2:00 P.M. (New York, New York time) on the fifth Business Day prior to the date of the proposed issuance of such Letter of Credit (or such later day as the Issuing Bank in its sole discretion shall agree), by the Borrower to the Issuing Bank, which shall give to the Administrative Agent and each Revolving Credit Lender prompt notice thereof. Each notice of issuance of a Letter of Credit (a “Notice of Issuance”) shall be by telephone, confirmed immediately in writing, or by telecopier, shall be duly executed by a Responsible Officer of the Borrower, and shall specify therein: (i) the requested date of such issuance (which shall be a Business Day); (ii) the requested Available Amount of such Letter of Credit; (iii) the requested expiration date of such Letter of Credit (which shall comply with the requirements of Section 2.01(f)); (iv) the name and address of the proposed beneficiary of such Letter of Credit; and (v) the proposed form of such Letter of Credit, and shall be accompanied by such application and agreement for letters of credit as the Issuing Bank may specify to the Borrower for use in connection with such requested Letter of Credit (such applications and agreements, and all similar agreements entered into in connection with an Existing Letter of Credit, a “Letter of Credit Agreement”). If the requested form of such Letter of Credit is acceptable to the Issuing Bank in its sole discretion, the Issuing Bank will, upon fulfillment of the applicable conditions set forth in Article III, make such Letter of Credit available to the Borrower at its office referred to in Section 8.02 or as otherwise agreed with the Borrower in connection with the issuance of such Letter of Credit. If and to the extent that the provisions of any Letter of Credit Agreement shall conflict with this Agreement, the provisions of this Agreement shall govern.

(b) Drawing and Reimbursement.

(i) The obligation of the Borrower to reimburse the Issuing Bank for each payment made by the Issuing Bank under any Letter of Credit, and to pay interest thereon as provided herein, shall be absolute, unconditional and irrevocable, without regard to any circumstances, including, without limitation, those referred to in Section 2.04(d) below. The payment by the Issuing Bank of a draft drawn under any Letter of Credit shall constitute for all purposes of this Agreement the making by the Issuing Bank of a Letter of Credit Advance, which shall be a Base Rate Advance, in the amount of such draft; provided that such payment shall not be deemed a Base Rate Advance if the Borrower reimburses the Issuing Bank therefor prior to 2:00 P.M. (New York, New York time) on the date of such payment, or if such payment by the Issuing Bank is made on or after 2:00 P.M. (New York, New York time), then prior to 2:00 P.M. (New York, New York time), on the Business Day immediately succeeding the date of such payment, together with interest thereon from the date of such payment to the date of such reimbursement at a rate per annum equal to the sum of the Base Rate then in effect from time to time and the Applicable Margin for Base Rate Advances that are Revolving Credit Advances then in effect from time to time. Upon demand by the Issuing Bank,

with a copy of such demand to the Administrative Agent (which shall give prompt notice thereof to each Revolving Credit Lender), each Revolving Credit Lender shall purchase from the Issuing Bank, and the Issuing Bank shall sell and assign to each such Revolving Credit Lender, such Lender’s Pro Rata Share of such outstanding Letter of Credit Advance as of the date of such purchase, by making available for the account of its Applicable Lending Office to the Administrative Agent for the account of the Issuing Bank, at the Administrative Agent’s Account, in same day funds, an amount equal to the portion of the outstanding principal amount of such Letter of Credit Advance to be purchased by such Lender. Promptly after receipt thereof, the Administrative Agent shall transfer such funds to the Issuing Bank. The Borrower hereby agrees to each such sale and assignment. Each Revolving Credit Lender agrees to purchase its Pro Rata Share of an outstanding Letter of Credit Advance on (A) the Business Day on which demand therefor is made by the Issuing Bank so long as notice of such demand is given not later than 2:00 P.M. (New York, New York time) on such Business Day or (B) the first Business Day next succeeding such demand if notice of such demand is given after such time. Upon any such assignment by the Issuing Bank to any other Revolving Credit Lender of a portion of a Letter of Credit Advance, the Issuing Bank represents and warrants to such other Lender that the Issuing Bank is the legal and beneficial owner of such interest being assigned by it, free and clear of any liens, but makes no other representation or warranty and assumes no responsibility with respect to such Letter of Credit Advance, the Loan Documents or any Loan Party. If and to the extent that any Revolving Credit Lender shall not have so made the amount of such Letter of Credit Advance available to the Administrative Agent, such Revolving Credit Lender agrees to pay to the Administrative Agent forthwith on demand such amount, together with interest thereon, for each day from the date of demand by the Issuing Bank until the date such amount is paid to the Administrative Agent, at the Federal Funds Rate, for its account or the account of the Issuing Bank, as applicable. If such Revolving Credit Lender shall pay to the Administrative Agent such amount for the account of the Issuing Bank on any Business Day, such amount so paid in respect of principal shall constitute a Letter of Credit Advance made by such Revolving Credit Lender on such Business Day for all purposes of this Agreement, and the outstanding principal amount of the Letter of Credit Advance made by the Issuing Bank shall be reduced by such amount on such Business Day.

(ii) The Obligation of each Revolving Credit Lender to purchase its Pro Rata Share of each outstanding Letter of Credit Advance upon demand by the Issuing Bank therefor pursuant to clause (i) of this Section 2.03(b) shall be absolute, unconditional and irrevocable, and shall be made strictly in accordance with the terms of clause (i) of this Section 2.03(b) under all circumstances, including, without limitation, the following circumstances:

(A) any lack of validity or enforceability of any Loan Document, any Letter of Credit Agreement, any Letter of Credit or any other agreement or instrument relating thereto (collectively, the “L/C Related Documents”);

(B) the existence of any claim, set-off, defense or other right that such Revolving Credit Lender may have at any time against any beneficiary or any transferee of a Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the Issuing Bank, the Borrower or any other Person, whether in connection with the transactions contemplated by the L/C Related Documents or any unrelated transaction;

(D) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

(c) Failure to Make Letter of Credit Advances. The failure of any Revolving Credit Lender to make the Letter of Credit Advance to be made by it on the date specified in Section 2.03(b) shall not relieve any other Revolving Credit Lender of its obligation hereunder to make its Letter of Credit Advance on such date, but no Revolving Credit Lender shall be responsible for the failure of any other Revolving Credit Lender to make the Letter of Credit Advance to be made by such other Revolving Credit Lender on such date.

SECTION 2.04. Repayment of Advances.

(a) Term Advances. The Borrower shall repay to the Administrative Agent for the ratable account of the Appropriate Lenders the aggregate principal amount of all Term Advances outstanding on the following dates in the respective amounts set forth opposite such dates (which amounts shall be reduced as a result of the application of prepayments in accordance with the order of priority set forth in Section 2.06):

Any Term B Lender or Term C Lender may elect (upon such election, such Term B Lender or Term C Lender being a “Declining Lender”), by notice to the Administrative Agent in writing (or by telecopy or telephone promptly confirmed in writing) by 12:00 p.m., New York, New York time, at least two Business Days prior to any prepayment of Term B Advances or Term C Advances, as applicable, required to be made by the Borrower for the account of such Declining Lender pursuant to this Section 2.06(d), not to accept the portion of such prepayment to which such Declining Lender would be entitled and upon such election, such declined amount shall be applied instead to prepay a portion of the Term A Advances (to the extent Term A Advances remain outstanding after giving effect to such prepayment of the Term A Advances) in accordance with subsection 2.06(b)(i) above and this subsection 2.06(d). On the date of such prepayment (the “Prepayment Date”), (i) an amount equal to that portion of the prepayment required to be made to the Term B Lenders or the Term C Lenders, as the case may be, other than the Declining Lenders (such Term B Lenders or such Term C Lenders, as applicable, being the “Accepting Lenders”) shall be applied by the Administrative Agent on behalf of the Borrower to prepay Term B Advances or Term C

Advances, as the case may be, owing to such Accepting Lenders on a pro rata basis as provided above, (ii) fifty percent of any amounts that would otherwise have been applied to prepay Advances under the Term B Facility or the Term C Facility, as applicable, owing to Declining Lenders shall instead be applied ratably to prepay the remaining Term A Advances owing to Term A Lenders as provided above, and (iii) the remaining fifty percent of such amounts shall be credited to the Borrower’s Account; provided that on prepayment in full of all Term B Advances or Term C Advances, as the case may be, owing to Accepting Lenders and all Term A Advances owing to Term A Lenders, the remainder of such amounts under subsection (ii) shall be applied ratably to prepay Term B Advances or Term C Advances, as applicable, owing to Declining Lenders.

SECTION 2.07. Interest. (a) Scheduled Interest. The Borrower shall pay interest on the unpaid principal amount of each Advance owing to each Lender Party from the date of such Advance (which for purposes of each Term A Advance, Term B Advance and Revolving Credit Advance outstanding on the Closing Date shall be the date of each such Advance under the Existing Credit Agreement) until such principal amount shall be paid in full, at the following rates per annum:

(B) no Conversion of any Advances shall result in more separate Borrowings than permitted under Section 2.02(c); and

Each notice of a Conversion (a “Notice of Conversion”) shall be delivered by telephone, confirmed immediately in writing, or by telecopier, in substantially the form of Exhibit B-3 hereto, shall be duly executed by a Responsible Officer of the Borrower, and shall, within the restrictions set forth in the immediately preceding sentence, specify therein:

(b) Mandatory.

(i) On the last day of any Interest Period during which the aggregate unpaid principal amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced, by payment or prepayment or otherwise, to less than $5,000,000, such Advances shall automatically Convert into Base Rate Advances.

SECTION 2.10. Increased Costs, Etc. (a) If, after the date hereof, the adoption of any applicable Requirement of Law, or any change in any applicable Requirement of Law, or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency:

(i) shall subject such Lender (or its Applicable Lending Office) to any tax, duty, or other charge with respect to any Eurodollar Rate Advances, any of its Notes, or its obligation to make any Eurodollar Rate Advances, or change the basis of taxation of any amounts payable to such Lender (or its Applicable Lending Office) under this Agreement or its Note in respect of any Eurodollar Rate Advances (other than, for purposes of this Section 2.10, any such increased costs resulting from (A) Taxes or Other Taxes (as to which Section 2.13 shall govern), and (B) changes in the basis of taxation of overall net income or overall gross income by the United States of America or the jurisdiction under the laws of which such Lender Party has its principal office or such Applicable Lending Office);

(ii) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Lender (or its Applicable Lending Office), including the Commitments of such Lender hereunder; or

(iii) shall impose on such Lender (or its Applicable Lending Office) or on the United States market for certificates of deposit or the London interbank market any other condition affecting this Agreement or its Note or any of such extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender (or its Applicable Lending Office) of making, Converting into or maintaining any Eurodollar Rate Advances or to reduce any sum received or receivable by such Lender (or its Applicable Lending Office) under this Agreement or its Note with respect to any Eurodollar Rate Advances, then the Borrower shall pay to such Lender on demand such amount or amounts as will compensate such Lender for such increased cost or reduction. Each Lender shall promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 2.10(a) and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to it (other than by reason of administrative convenience or preference). Any Lender claiming compensation under this Section 2.10(a) shall furnish to the Borrower and the Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder (including the method of calculation), which shall be conclusive and binding, absent manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. If any Lender requests compensation by the Borrower under this Section 2.10(a), the Borrower may, by notice to such Lender (with a copy to the Administrative Agent), suspend the obligation of such Lender to make or Convert Eurodollar Rate Advances, or to Convert Base Rate Advances into Eurodollar Rate Advances, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 2.10(e) shall be applicable); provided that such suspension shall not affect the right of such Lender to receive the compensation so requested.

(b) If, after the date hereof, any Lender shall have determined that the adoption of any applicable Requirement of Law regarding capital adequacy or any change therein or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Lender or any corporation controlling such Lender as a consequence of such Lender’s obligations hereunder to a level below that which such Lender or such corporation could have achieved but for such adoption, change, request or directive (taking into consideration its policies with respect to capital adequacy), then from time to time upon demand the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each Lender shall promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 2.10(b) and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming compensation under this Section 2.10(b) shall furnish to the Borrower and the Administrative Agent a statement setting forth the additional amount or amounts to be paid to it hereunder (including the method of calculation), which shall be conclusive and binding, absent manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

(c) If, on or prior to the first day of any Interest Period for any Eurodollar Rate Advance, the Required Lenders at any time notify the Administrative Agent that the Eurodollar Rate for any Interest Period for such Advances will not adequately and fairly reflect the cost to the Appropriate Lenders of funding their Eurodollar Rate Advances for such Interest Period, the Administrative Agent shall promptly so notify the Borrower and the Appropriate Lenders, whereupon (i) each such Eurodollar Rate Advance will automatically, on the last day of the then

existing Interest Period therefor, Convert into a Base Rate Advance and (ii) the obligation of the Appropriate Lenders to make, or to Convert Advances into, Eurodollar Rate Advances shall be suspended until the Administrative Agent shall notify the Borrower (promptly following notice from the Appropriate Lenders) that such Lenders have determined that the circumstances causing such suspension no longer exist.

(d) Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to make, maintain, or fund Eurodollar Rate Advances hereunder, then such Lender shall promptly notify the Borrower thereof and such Lender’s obligation to make Eurodollar Rate Advances and to Convert Base Rate Advances into Eurodollar Rate Advances shall be suspended until such time as such Lender may again make, maintain and fund Eurodollar Rate Advances (in which case the provisions of Section 2.10(e) shall be applicable).

(e) If the obligation of any Lender to make a Eurodollar Rate Advance or to Convert Base Rate Advances into Eurodollar Rate Advances shall be suspended pursuant to any other provision of this Section 2.10, such Lender’s suspended Eurodollar Rate Advances shall be automatically Converted into Base Rate Advances on the last day(s) of the then current Interest Period(s) therefor (or, in the case of a Conversion required by Section 2.10(d), on such earlier date as such Lender may specify to the Borrower with a copy to the Administrative Agent) and, unless and until such Lender gives notice as provided below that the circumstances specified in such other provision of this Section 2.10 that gave rise to such Conversion no longer exist:

(i) to the extent that such Lender’s suspended Eurodollar Rate Advances have been so Converted, all payments and prepayments of principal that would otherwise be applied to such Lender’s suspended Eurodollar Rate Advances shall be applied instead to its Base Rate Advances; and

(ii) all Eurodollar Rate Advances that would otherwise be made or Converted by such Lender shall be made instead as (or shall remain as) Base Rate Advances.

If such Lender gives notice to the Borrower (with a copy to the Administrative Agent) that the circumstances otherwise specified in this Section 2.10 that gave rise to the suspension of the making of Eurodollar Rate Advances by such Lender no longer exist (which such Lender agrees to do promptly upon such circumstances ceasing to exist) at a time when Eurodollar Rate Advances by other Lenders with Commitments under the same Facility are outstanding, such Lender’s Base Rate Advances shall be automatically Converted, on the first day(s) of the next succeeding Interest Period(s) therefor, to the extent necessary into Eurodollar Rate Advances.

SECTION 2.11. Evidence of Debt. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the debt of the Borrower to such Lender resulting from each Advance owing to such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b) The Register maintained by the Administrative Agent pursuant to Section 8.07(c) shall include accounts for each Lender, in which accounts (taken together) shall be recorded (i) the date and amount of each Advance made hereunder, (ii) the terms of each Assignment and Assumption delivered to and accepted by it, (iii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iv) the amount of any sum received by the Administrative Agent from the Borrower hereunder and each Lender’s share thereof.

(c) The entries made as provided in this Section 2.11 shall be conclusive and binding for all purposes, absent manifest error.

SECTION 2.12. Payments and Computations. (a) The Borrower shall make each payment hereunder and under the Notes, irrespective of any right of counterclaim, deduction or set-off (except as otherwise provided in Section 2.16), not later than 2:00 P.M. (New York, New York time) on the day when due in U.S. dollars to the Administrative Agent at the Administrative Agent’s Account in same day funds, with payments received by the Administrative Agent after such time being deemed to have been received on the next succeeding Business Day. The Administrative Agent will promptly thereafter cause like funds to be distributed (i) if such payment by the Borrower is in respect of principal, interest, commitment fees or any other Obligation then due and payable hereunder and under the Notes to more than one Lender Party, to such Lender Parties for the accounts of their respective Applicable Lending Offices in accordance with their respective Pro Rata Shares of the amounts of such respective Obligations due and payable to such Lender Parties at such time and (ii) if such payment by the Borrower is in respect of any Obligation then due and payable hereunder solely to one Lender Party, to such Lender Party for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon its acceptance of an Assignment and Assumption and recording of the information contained therein in the Register pursuant to Section 8.07(c), from and after the effective date of such Assignment and Assumption, the Administrative Agent shall make all payments hereunder and under the Notes in respect of the interest assigned thereby to the Lender Party assignee thereunder, and the parties to such Assignment and Assumption shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

(b) The Borrower hereby authorizes each Lender Party, if and to the extent payment owed to such Lender Party is not made when due hereunder or, in the case of a Lender, under the Note held by such Lender, to charge from time to time against any or all of the Borrower’s accounts with such Lender Party any amount so due.

(c) All computations of interest based on the Base Rate shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate and of the letter of credit commissions and commitment or letter of credit fees payable hereunder shall be made by the Administrative Agent on the basis of a year of 360 days, in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest, fees or commissions are payable. Each determination by the Administrative Agent of an interest rate, fee or commission hereunder shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under the Notes shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest, letter of credit commissions or commitment or letter of credit fees, as the case may be; provided, however, that, if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next succeeding calendar month, such payment shall be made on the immediately preceding Business Day.

(e) Unless the Borrower or any Lender Party has notified the Administrative Agent prior to the date any payment is required to be made by it to the Administrative Agent hereunder,

that the Borrower or such Lender Party, as the case may be, will not make such payment, the Administrative Agent may assume that the Borrower or such Lender Party, as the case may be, has timely made such payment and may (but shall not be so required to), in reliance thereon, make available a corresponding amount to the Person entitled thereto. If and to the extent that such payment was not in fact made to the Administrative Agent in immediately available funds, then:

(i) if the Borrower failed to make such payment, each Lender Party shall forthwith on demand repay to the Administrative Agent the portion of such assumed payment that was made available to such Lender Party in immediately available funds, together with interest thereon in respect of each day from and including the date such amount was made available by the Administrative Agent to such Lender Party to the date such amount is repaid to the Administrative Agent in immediately available funds, at the Federal Funds Rate from time to time in effect; and

(ii) if any Lender Party failed to make such payment, such Lender Party shall forthwith on demand pay to the Administrative Agent the amount thereof in immediately available funds, together with interest thereon for the period from the date such amount was made available by the Administrative Agent to the Borrower to the date such amount is recovered by the Administrative Agent (the “Compensation Period”) at a rate per annum equal to the Federal Funds Rate from time to time in effect. If such Lender Party pays such amount to the Administrative Agent, then such amount shall constitute such Lender Party’s Advance included in the applicable Borrowing. If such Lender Party does not pay such amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent may make a demand therefor upon the Borrower, and the Borrower shall pay such amount to the Administrative Agent, together with interest thereon for the Compensation Period at a rate per annum equal to the rate of interest applicable to the applicable Borrowing. Nothing herein shall be deemed to relieve any Lender Party from its obligation to fulfill its applicable Commitment or to prejudice any rights which the Administrative Agent or the Borrower may have against any Lender Party as a result of any default by such Lender Party hereunder.

A notice from the Administrative Agent to any Lender Party with respect to any amount owing under this subsection (e) shall be conclusive, absent manifest error.

(f) Whenever any payment received by the Administrative Agent under this Agreement or any of the other Loan Documents is insufficient to pay in full all amounts due and payable to the Agents and the Lender Parties under or in respect of this Agreement and the other Loan Documents on any date, such payment shall be distributed by the Administrative Agent and applied by the Agents and the Lender Parties in the following order of priority:

(i) first, to the payment of all of the fees, indemnification payments, costs and expenses that are due and payable to the Agents (solely in their respective capacities as Agents) under or in respect of this Agreement and the other Loan Documents on such date, ratably based upon the respective aggregate amounts of all such fees, indemnification payments, costs and expenses owing to the Agents on such date;

(ii) second, to the payment of all of the fees, indemnification payments, costs and expenses that are due and payable to the Issuing Bank and the Swing Line Bank (solely in their respective capacities as such) under or in respect of this Agreement and the other Loan Documents on such date, ratably based upon the respective aggregate amounts of all such fees, indemnification payments, costs and expenses owing to the Issuing Bank and the Swing Line Bank on such date;

(iii) third, to the payment of all of the indemnification payments, costs and expenses that are due and payable to the Lenders under Section 8.04 hereof, Section 12 of the Subsidiary Guarantee, Section 21 of the Security Agreement and any similar section of any of the other Loan Documents on such date, ratably based upon the respective aggregate amounts of all such indemnification payments, costs and expenses owing to the Lenders on such date;

(iv) fourth, to the payment of all of the amounts that are due and payable to the Administrative Agent and the Lender Parties under Sections 2.10 and 2.13 hereof and Section 5 of the Subsidiary Guarantee on such date, ratably based upon the respective aggregate amounts thereof owing to the Administrative Agent and the Lender Parties on such date;

(v) fifth, to the payment of all of the accrued and unpaid interest on the Obligations of the Borrower under or in respect of the Loan Documents that is due and payable to the Administrative Agent and the Lender Parties under Section 2.07(a) on such date and all of the fees that are due and payable to the Lenders or the Issuing Bank under Section 2.08(a) or 2.08(b) on such date, ratably based upon the respective aggregate Commitments of the Lenders under the Facilities on such date;

(vi) sixth, to the payment of the principal amount of all of the outstanding Advances that is due and payable to the Administrative Agent and the Lender Parties on such date, ratably based upon the respective aggregate amounts of all such principal owing to the Administrative Agent and the Lender Parties on such date; and

(vii) seventh, to the payment of all other Obligations of the Loan Parties owing under or in respect of the Loan Documents that are due and payable to the Administrative Agent and the other Secured Parties on such date, ratably based upon the respective aggregate amounts of all such Obligations owing to the Administrative Agent and the other Secured Parties on such date.

If the Administrative Agent receives funds for application to the Obligations of the Loan Parties under or in respect of the Loan Documents under circumstances for which the Loan Documents do not specify the Advances or the Facility to which, or the manner in which, such funds are to be applied, the Administrative Agent may, but shall not be obligated to, elect to distribute such funds to each of the Lender Parties in accordance with such Lender Party’s Pro Rata Share of the sum of (A) the aggregate principal amount of all Advances outstanding at such time and (b) the aggregate Available Amount of all Letters of Credit outstanding at such time, in repayment or prepayment of such of the outstanding Advances or other Obligations then owing to such Lender Party, and, in the case of the Term Facility, for application to such principal repayment installments thereof, as the Administrative Agent shall direct.

SECTION 2.13. Taxes. (a) Any and all payments by the Borrower to or for the account of any Lender Party or any Agent hereunder or under any other Loan Document shall be made, in accordance with Section 2.12 or the applicable provisions of such other Loan Document, if any, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender Party and each Agent, taxes that are imposed on its overall net income by the United States and taxes that are imposed on

its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction under the laws of which such Lender Party or such Agent, as the case may be, is organized or is a resident, or has a fixed place of business or a permanent establishment, or any political subdivision of any of the foregoing, and, in the case of each Lender Party, taxes that are imposed on its overall net income (and franchise taxes imposed in lieu thereof) by the state or foreign jurisdiction of either of its Applicable Lending Offices or any political subdivision thereof (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and liabilities in respect of payments hereunder or under the Notes being, collectively, “Taxes”). If the Borrower shall be required under applicable Requirements of Law to deduct any Taxes from or in respect of any sum payable hereunder or under any other Loan Document to any Lender Party or any Agent, (i) the sum payable by the Borrower shall be increased as necessary so that after the Borrower and the Administrative Agent have been made all required deductions (including deductions applicable to additional sums payable under this Section 2.13) such Lender Party or such Agent, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other Governmental Authority in accordance with applicable Requirements of Law and (iv) within 30 days after the date of any payment of Taxes, the Borrower shall furnish to the Administrative Agent, at its address referred to in Section 8.02, the original or a certified copy of a receipt evidencing payment thereof, to the extent such a receipt is issued therefor, or other written proof of payment thereof that is reasonably satisfactory to the Administrative Agent.

(b) In addition, the Borrower agrees to pay any present or future stamp, recording or documentary, excise, property or similar taxes, charges or levies that arise from any payment made hereunder or under any other Loan Document or from the execution, delivery of, or registration of, any performance under, or otherwise with respect to, this Agreement or any other Loan Document (collectively, “Other Taxes”).

(c) The Borrower shall indemnify each of the Lender Parties and each of the Agents for, and hold each of them harmless against, the full amount of Taxes and Other Taxes, and the full amount of taxes of any kind imposed by any jurisdiction on amounts payable under this Section 2.13, imposed on or paid by such Lender Party or such Agent, as the case may be, and any liability (including penalties, additions to tax, interest and expenses) arising therefrom or with respect thereto. The indemnity by the Borrower provided for in this subsection (c) shall apply and be made whether or not the Taxes or Other Taxes for which indemnification hereunder is sought have been correctly or legally asserted; provided, however, that such Lender or such Agent seeking such indemnification shall take all reasonable actions (consistent with its internal policy and legal and regulatory restrictions) requested by the Borrower to assist the Borrower in recovering the amounts paid thereby pursuant to this subsection (c) from the relevant taxation authority or other Governmental Authority. Amounts payable by the Borrower under the indemnity set forth in this subsection (c) shall be paid within 30 days from the date on which the applicable Lender or Agent, as the case may be, makes written demand therefor (including the method of calculation).

(d) In the case of any payment hereunder or under any other Loan Document by or on behalf of the Borrower through an account or branch outside the United States, or on behalf of the Borrower by a payor that is not a United States person, if the Borrower determines that no Taxes are payable in respect thereof, the Borrower shall furnish, or shall cause such payor to furnish, to the Administrative Agent, at its address referred to in Section 8.02, an opinion of counsel reasonably acceptable to the Administrative Agent stating that such payment is exempt from Taxes. For purposes of this subsection (d) and subsection (e) of this Section 2.13, the terms “United States” and “United States person” shall have the meanings specified in Section 7701 of the Internal Revenue Code.

(e) Each Lender Party organized under the laws of a jurisdiction outside the United States shall, on or prior to the date of its execution and delivery of this Agreement in the case of each Initial Lender, the Swing Line Bank or the Initial Issuing Bank, as the case may be, and on or prior to the date of the Assignment and Assumption pursuant to which it becomes a Lender Party in the case of each other Lender Party, and from time to time thereafter as reasonably requested in writing by the Borrower (but only so long thereafter as such Lender Party remains lawfully able to do so), provide each of the Administrative Agent and the Borrower with two original Internal Revenue Service forms W-8BEN, W-8ECI or W-8IMY, or in the case of a Lender Party that has certified in writing to the Administrative Agent that it is claiming exemption from United States withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with respect to payments of “portfolio interest” from W-8BEN), (and, if such Lender Party delivers a form W-8BEN, a certificate representing that such Lender Party is not (i) a “bank” for purposes of Section 881(c) of the Internal Revenue Code, (ii) a ten-percent shareholder (within the meaning of Section 871(h)(3)(B) of the Internal Revenue Code) of the Borrower or (iii) a controlled foreign corporation related to the Borrower (within the meaning of Section 864(d)(4) of the Internal Revenue Code)), as appropriate, or any successor or other form prescribed by the Internal Revenue Service, certifying that such Lender Party is exempt from or entitled to a reduced rate of United States withholding tax on payments pursuant to this Agreement or any other Loan Document or, in the case of a Lender Party providing a form W-8BEN, certifying that such Lender Party is a foreign corporation, partnership, estate or trust. If any such forms provided by a Lender Party at the time such Lender Party first becomes a party to this Agreement indicate a United States interest withholding tax rate in excess of zero, withholding tax at such rate shall be considered excluded from Taxes unless and until such Lender Party provides the appropriate form certifying that a lesser rate applies, whereupon withholding tax at such lesser rate only shall be considered excluded from Taxes solely for the periods governed by such forms. However, if at the date of the Assignment and Assumption pursuant to which a Lender Party becomes a party to this Agreement, the Lender Party assignor was entitled to payments under subsection (a) of this Section 2.13 in respect of United States withholding tax with respect to interest paid at such date, then, to such extent, the term Taxes shall include (in addition to withholding taxes that may be imposed in the future or other amounts otherwise includable in Taxes) United States withholding tax, if any, applicable with respect to the Lender Party assignee on such date. None of the Lender Parties shall be entitled to payment pursuant to subsection (a) or (c) of this Section 2.13 with respect to any additional Taxes that result solely and directly from a change in either of the Applicable Lending Offices of such Lender Party (other than any such additional Taxes that are imposed as a result of a change in the applicable Requirements of Law, or in the interpretation of application thereof, occurring after the date of such change), unless such change is made pursuant to the terms of Section 2.10(e) or subsection (g) of this Section 2.13 or as a result of a request therefor by the Borrower.

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

(g) Each of the Lender Parties hereby agrees that, upon the occurrence of any circumstances entitling such Lender Party to additional amounts pursuant to this Section 2.13, such Lender Party shall use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such a change would avoid the need for, or reduce the amount of, any such additional amounts that may thereafter accrue and would not, in the reasonable judgment of such Lender Party, be otherwise disadvantageous to such Lender Party (other than by reason of administrative convenience or preference).

SECTION 2.14. Sharing of Payments, Etc. If any Lender Party shall obtain at any time any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) (a) on account of Obligations due and payable to such Lender Party under or in respect of this Agreement or any of the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations due and payable to such Lender Party at such time (other than pursuant to Section 2.10, 2.13, 8.04 or 8.07) to (ii) the aggregate amount of the Obligations due and payable to all Lender Parties at such time) of payments on account of the Obligations due and payable to all Lender Parties under or in respect of this Agreement and the other Loan Documents at such time obtained by all the Lender Parties at such time or (b) on account of Obligations owing (but not due and payable) to such Lender Party under or in respect of this Agreement or any of the other Loan Documents at such time in excess of its ratable share (according to the proportion of (i) the amount of such Obligations owing to such Lender Party at such time (other than pursuant to Section 2.10, 2.13, 8.04 or 8.07) to (ii) the aggregate amount of the Obligations owing (but not due and payable) to all Lender Parties under or in respect of this Agreement and the other Loan Documents at such time) of payments on account of the Obligations owing (but not due and payable) to all Lender Parties under or in respect of this Agreement and the other Loan Documents at such time obtained by all of the Lender Parties at such time, such Lender Party shall forthwith purchase from the other Lender Parties such interests or participating interests in the Obligations due and payable or owing to them, as the case may be, as shall be necessary to cause such purchasing Lender Party to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender Party, such purchase from each other Lender Party shall be rescinded and such other Lender Party shall repay to the purchasing Lender Party the purchase price to the extent of such Lender Party’s ratable share (according to the proportion of (A) the purchase price paid to such Lender Party to (B) the aggregate purchase price paid to all Lender Parties) of such recovery, together with an amount equal to such Lender Party’s ratable share (according to the proportion of (1) the amount of such other Lender Party’s required repayment to (2) the total amount so recovered from the purchasing Lender Party) of any interest or other amount paid or payable by the purchasing Lender Party in respect of the total amount so recovered; provided further that, so long as the Obligations under the Loan Documents shall not have been accelerated, any excess payment received by any Appropriate Lender shall be shared on a pro rata basis only with other Appropriate Lenders. The Borrower hereby agrees that any Lender Party so purchasing an interest or participating interest from another Lender Party pursuant to this Section 2.14 may, to the fullest extent permitted under applicable law, exercise all its rights of payment (including the right of setoff) with respect to such an interest or participating interest, as the case may be, as fully as if such Lender Party were the direct creditor of the Borrower in the amount of such an interest or participating interest.

SECTION 2.15. Use of Proceeds. The proceeds of the Term A Advances and the Term B Advances were used as provided in the Existing Credit Agreement. The proceeds of the Term C Advances and the Revolving Credit Advances shall be available (and the Borrower agrees that it shall use such proceeds) solely for acquisitions as permitted herein, for working capital and for general corporate purposes of the Borrower and its subsidiaries.

SECTION 2.16. Defaulting Lenders. (a) In the event that, at any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such Defaulting Lender shall owe a Defaulted Advance to the Borrower and (iii) the Borrower shall be required to make any payment hereunder or under any other Loan Document to or for the account of such Defaulting Lender, then the Borrower may, so long as no Default shall occur or be continuing at such time and to the fullest extent permitted by applicable law, set off and otherwise apply the Obligation of the Borrower to make such payment to or for the account of such Defaulting Lender against the obligation of such Defaulting Lender to make such Defaulted Advance. In the event that, on any date, the Borrower shall so set off and otherwise apply its obligation to make any such payment against the obligation of such Defaulting Lender to make any such Defaulted Advance on or prior to such date, the amount so set off and otherwise applied by the Borrower shall constitute for all purposes of this Agreement and the other Loan Documents an Advance by such Defaulting Lender made on the date of such setoff under the Facility pursuant to which such Defaulted Advance was originally required to have been made pursuant to Section 2.01. Such Advance shall be a Base Rate Advance and shall be considered, for all purposes of this Agreement, to comprise part of the Borrowing in connection with which such Defaulted Advance was originally required to have been made pursuant to Section 2.01, even if the other Advances comprising such Borrowing shall be Eurodollar Rate Advances on the date such Advance is deemed to be made pursuant to this subsection (a). The Borrower shall notify the Administrative Agent at any time the Borrower exercises its right of set-off pursuant to this subsection (a) and shall set forth in such notice (A) the name of the Defaulting Lender and the Defaulted Advance required to be made by such Defaulting Lender and (B) the amount set off and otherwise applied in respect of such Defaulted Advance pursuant to this subsection (a). Any portion of such payment otherwise required to be made by the Borrower to or for the account of such Defaulting Lender which is paid by the Borrower, after giving effect to the amount set off and otherwise applied by the Borrower pursuant to this subsection (a), shall be applied by the Administrative Agent as specified in subsection (b) or (c) of this Section 2.16.

(b) In the event that, at any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such Defaulting Lender shall owe a Defaulted Amount to the Administrative Agent or any of the other Lender Parties and (iii) the Borrower shall make any payment hereunder or under any other Loan Document to the Administrative Agent for the account of such Defaulting Lender, then the Administrative Agent may, on its behalf or on behalf of such other Lender Parties and to the fullest extent permitted by applicable law, apply at such time the amount so paid by the Borrower to or for the account of such Defaulting Lender to the payment of each such Defaulted Amount to the extent required to pay such Defaulted Amount. In the event that the Administrative Agent shall so apply any such amount to the payment of any such Defaulted Amount on any date, the amount so applied by the Administrative Agent shall constitute for all purposes of this Agreement and the other Loan Documents payment, to such extent, of such Defaulted Amount on such date. Any such amount so applied by the Administrative Agent shall be retained by the Administrative Agent or distributed by the Administrative Agent to such other Lender Parties, ratably in accordance with the respective portions of such Defaulted Amounts payable at such time to the Administrative Agent and such other Lender Parties and, if the amount of such payment made by the Borrower shall at such time be insufficient to pay all Defaulted Amounts owing at such time to the Administrative Agent and the other Lender Parties, in the following order of priority:

(A) first, to the Administrative Agent for any Defaulted Amount then owing to the Administrative Agent;

(B) second, to the Issuing Bank and the Swing Line Bank for any Defaulted Amount then owing to them, in their capacities as such, ratably in accordance with such respective Defaulted Amounts then owing to such Issuing Bank and such Swing Line Bank; and

(C) third, to any other Lender Parties for any Defaulted Amounts then owing to such other Lender Parties, ratably in accordance with such respective Defaulted Amounts then owing to such other Lender Parties.

Any portion of such amount paid by the Borrower for the account of such Defaulting Lender remaining, after giving effect to the amount applied by the Administrative Agent pursuant to this subsection (b), shall be applied by the Administrative Agent as specified in subsection (c) of this Section 2.16.

(c) In the event that, at any one time, (i) any Lender Party shall be a Defaulting Lender, (ii) such Defaulting Lender shall not owe a Defaulted Advance or a Defaulted Amount and (iii) the Borrower, the Administrative Agent or any other Lender Party shall be required to pay or distribute any amount hereunder or under any other Loan Document to or for the account of such Defaulting Lender, then the Borrower or such other Lender Party shall pay such amount to the Administrative Agent to be held by the Administrative Agent, to the fullest extent permitted by applicable law, in escrow or the Administrative Agent shall, to the fullest extent permitted by applicable law, hold in escrow such amount otherwise held by it. Any funds held by the Administrative Agent in escrow under this subsection (c) shall be deposited by the Administrative Agent in an account with CSFB, in the name and under the control of the Administrative Agent, but subject to the provisions of this subsection (c). The terms applicable to such account, including the rate of interest payable with respect to the credit balance of such account from time to time, shall be CSFB’s standard terms applicable to escrow accounts maintained with it. Any interest credited to such account from time to time shall be held by the Administrative Agent in escrow under, and applied by the Administrative Agent from time to time in accordance with the provisions of, this subsection (c). The Administrative Agent shall, to the fullest extent permitted by applicable law, apply all funds so held in escrow from time to time to the extent necessary to make any Advances required to be made by such Defaulting Lender and to pay any amount payable by such Defaulting Lender hereunder and under the other Loan Documents to the Administrative Agent or any other Lender Party, as and when such Advances or amounts are required to be made or paid and, if the amount so held in escrow shall at any time be insufficient to make and pay all such Advances and amounts required to be made or paid at such time, in the following order of priority:

(A) first, to the Administrative Agent for any amount then due and payable by such Defaulting Lender to the Administrative Agent hereunder;

(B) second, to the Issuing Bank and the Swing Line Bank for any amounts then due and payable to them hereunder, in their capacities as such, by such Defaulting Lender, ratably in accordance with such amounts then due and payable to such Issuing Bank and such Swing Line Bank;

(C) third, to any other Lender Parties for any amount then due and payable by such Defaulting Lender to such other Lender Parties hereunder, ratably in accordance with such respective amounts then due and payable to such other Lender Parties; and

(D) fourth, to the Borrower for any Advance then required to be made by such Defaulting Lender pursuant to a Commitment of such Defaulting Lender.

In the event that any Lender Party that is a Defaulting Lender shall, at any time, cease to be a Defaulting Lender, any funds held by the Administrative Agent in escrow at such time with respect to such Lender Party shall be distributed by the Administrative Agent to such Lender Party and applied by such Lender Party to the Obligations owing to such Lender Party at such time under this Agreement and the other Loan Documents ratably in accordance with the respective amounts of such Obligations outstanding at such time.

(d) The rights and remedies against a Defaulting Lender under this Section 2.16 are in addition to other rights and remedies that the Borrower may have against such Defaulting Lender with respect to any Defaulted Advance and that the Administrative Agent or any Lender Party may have against such Defaulting Lender with respect to any Defaulted Amount.

(d) No Governmental Authorization, and no other authorization or approval or other action by, and no notice to or filing with, any Governmental Authority or any other third party is required for (i) the due execution, delivery, recordation, filing or performance by any Loan Party of any Loan Document to which it is or is to be a party, or for the consummation of the Transaction, (ii) the grant by any Loan Party of the Liens granted by it pursuant to the Collateral Documents, (iii) the perfection or maintenance of the Liens created under the Collateral Documents on such of the Collateral located in the United States in which a Lien may be perfected by the filing of financing statements, the recordation of security agreements with the U.S. Patent and Trademark Office or the U.S. Copyright Office or the delivery of Collateral (including the first priority nature thereof) or (iv) the exercise by any Agent or any Lender Party of its rights under the Loan Documents or the remedies in respect of the Collateral pursuant to the Collateral Documents, except for (A) the authorizations, approvals, filings and actions on Schedule 4.01(d) hereto, all of which have been duly obtained and are in full force and effect or will be obtained and in full force and effect prior to the Closing Date, (B) filings, notices, recordings and other similar actions necessary for the creation or perfection of the Liens and security interests contemplated by the Loan Documents and (C) the actions required by laws generally with respect to the exercise by secured creditors of their rights and remedies.

(e) This Agreement has been, and each other Loan Document when delivered hereunder will have been, duly executed and delivered by each Loan Party thereto. This Agreement is, and each other Loan Document when delivered hereunder will be, the legal, valid and binding obligation of each Loan Party thereto, enforceable against such Loan Party in accordance with its terms.

(f) There is no action, suit, investigation, litigation or proceeding affecting any Loan Party or any of its Subsidiaries, including any Environmental Action, pending or, to the knowledge of the Borrower, threatened before any Governmental Authority or arbitrator that (i) could be reasonably likely to have a Material Adverse Effect or (ii) purports to affect the legality, validity or enforceability of any Loan Document or the consummation of the Transaction, except as described on Schedule 4.01(f) hereto or disclosed prior to the Closing Date in the Borrower’s filings made with the Securities and Exchange Commission.

(g) (i) The Consolidated balance sheet of the Borrower and its Subsidiaries as at December 31, 2003, and the related Consolidated statement of income and Consolidated statement of cash flows of the Borrower and its Subsidiaries for the fiscal year then ended, accompanied by an unqualified opinion of KPMG LLP, independent public accountants, copies of which have been furnished to each Lender Party, fairly present the Consolidated financial condition of the Borrower and its Subsidiaries as at such date and the Consolidated results of operations of the Borrower and its Subsidiaries for the period ended on such date, all in accordance with generally accepted accounting principles applied on a consistent basis, and (ii) since December 31, 2003, there has been no Material Adverse Change.

(h) The Consolidated forecasted balance sheet, statement of income and statement of cash flows of the Borrower and its Subsidiaries delivered to the Lender Parties pursuant to Section 3.01(a)(vi) or Section 5.03 were prepared in good faith on the basis of the assumptions stated therein, which assumptions were believed to be reasonable in light of the conditions existing at the time of delivery of such forecasts, and represented, at the time of delivery, the Borrower’s best estimate of its future financial performance.

(i) Neither the Information Memorandum nor any other information, exhibit or report furnished by any Loan Party to any Agent or any Lender Party in connection with the negotiation and syndication of the Loan Documents or pursuant to the terms of the Loan Documents contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements made therein not misleading.

(j) The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Advance or drawings under any Letter of Credit will be used to purchase or carry any Margin Stock or to extend credit to others for the purpose of purchasing or carrying any Margin Stock, except for the purchase by the Borrower of its common stock as contemplated in Sections 5.02(g)(iv) and (v).

Neither any Loan Party nor any of its Subsidiaries is a “holding company”, or a “subsidiary company” of a “holding company”, or an “affiliate” of a “holding company” or of a “subsidiary company” of a “holding company”, as such terms are defined in the Public Utility Holding Company Act of 1935, as amended. Neither the making of any Advances, nor the issuance of any Letters of Credit, nor the application of the proceeds or repayment thereof by the Borrower, nor the consummation of the other transactions contemplated by the Loan Documents and Related Documents, will violate any provision of any such Act or any rule, regulation or order of the Securities and Exchange Commission thereunder.

(l) Upon making of the filings and taking of the other actions necessary to create, perfect and protect the security interest in the Collateral created under the Collateral Documents, the Collateral Documents create in favor of the Administrative Agent for the benefit of the Secured Parties a valid and, together with such filings and other actions, perfected first priority security interest in the Collateral, securing the payment of the Secured Obligations, subject to Permitted Liens. The Loan Parties are the legal and beneficial owners of the Collateral free and clear of any Lien, except for the liens and security interests created or permitted under the Loan Documents.

The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless the Administrative Agent has received written notice from a Lender Party or the Borrower specifying such Default or Event of Default and stating that such notice is a “Notice of Default”. In the event that the Administrative Agent receives such a notice of the occurrence of a Default or Event of Default, the Administrative Agent shall give prompt notice thereof to the Lender Parties. The Administrative Agent shall (subject to Section 7.02) take such action with respect to such Default or Event of Default as shall reasonably be directed by the Required Lenders or, to the extent any action requires the consent of all Lenders as specifically provided in Section 8.01, then as directed by all Lenders; provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interest of the Lender Parties.

SECTION 7.04. CSFB and Affiliates. With respect to its Commitments, the Advances made by it and the Note or Notes issued to it, CSFB (and any successor acting as the Administrative Agent) in its capacity as a Lender Party hereunder shall have the same rights and powers under the Loan Documents as any other Lender Party and may exercise the same as though it were not acting as the Administrative Agent; and the term “Lender Party” or “Lender Parties” shall, unless otherwise expressly indicated, include CSFB in its individual capacity. CSFB (and any successor acting as the Administrative Agent), and its affiliates may (without having to account therefor to any Lender Party) accept deposits from, lend money to, make investments in, provide services to, and generally engage in any kind of lending, trust, or other business with any Loan Party or any of its Subsidiaries or Affiliates as if it were not acting as an Agent, and CSFB (and any successor acting as the Administrative Agent), and its affiliates may accept fees and other consideration from any Loan Party or any of its Subsidiaries or Affiliates, or any Person that may do business with or own securities of any Loan Party or any such Subsidiary or Affiliate, for services in connection with this Agreement or otherwise without having to account for the same to the Lender Parties.

SECTION 7.05. Indemnification.

(a) The Lenders severally agree to indemnify the Administrative Agent (to the extent not promptly reimbursed under Section 8.04, but without limiting the obligations of the Borrower under such Section) ratably in accordance with their respective Commitments, for any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses (including attorneys’ fees), or disbursements of any kind and nature whatsoever that may be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or

arising out of any Loan Document or the transactions contemplated thereby or any action taken or omitted by the Administrative Agent under any Loan Document (collectively, the “Indemnified Costs”); provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Person to be indemnified. In the case of any claim, investigation, litigation or proceeding for which indemnity under this Section 7.05(a) applies, such indemnity shall apply whether or not such claim, investigation, litigation or proceeding is brought by the Administrative Agent, any of the other Agents, any of the Lender Parties or a third party. Without limitation of the foregoing, each Lender severally agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any costs or expenses payable by the Borrower under Section 8.04, to the extent that the Administrative Agent is not promptly reimbursed for such costs and expenses (including, without limitation, fees and expenses of counsel) by the Borrower. In the case of any investigation, litigation or proceeding giving rise to any Indemnified Costs, this Section 7.05 applies whether any such investigation, litigation or proceeding is brought by any Lender Party or any other Person. The failure of any Lender Party to reimburse the Administrative Agent promptly upon demand for its ratable share of any amount required to be paid by the Lender Party to the Administrative Agent as provided herein shall not relieve any other Lender Party of its obligation hereunder to reimburse the Administrative Agent for its ratable share of such amount, but no Lender Party shall be responsible for the failure of any other Lender Party to reimburse the Administrative Agent for such other Lender Party’s ratable share of such amount. Without prejudice to the survival of any other agreement of any Lender Party hereunder, the agreement and obligations of each Lender contained in this Section 7.05(a) shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

(b) The Revolving Credit Lenders severally agree to indemnify the Issuing Bank (to the extent not promptly reimbursed under Section 8.04, but without limiting the obligations of the Borrower under such Section) for such Revolving Credit Lender’s Pro Rata Share of any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against the Issuing Bank in any way relating to or arising out of the Loan Documents or the transactions contemplated thereby or any action taken or omitted by the Issuing Bank under the Loan Documents; provided, however, that no Revolving Credit Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Issuing Bank’s gross negligence or willful misconduct. In the case of any claim, investigation, litigation or proceeding for which indemnity under this Section 7.05(b) applies, such indemnity shall apply whether or not such claim, investigation, litigation or proceeding is brought by the Issuing Bank, any of the other Lender Parties or a third party. Without limitation of the foregoing, each Revolving Credit Lender severally agrees to reimburse the Issuing Bank promptly upon demand for its Pro Rata Share of any costs and expenses (including, without limitation, fees and expenses of counsel) payable by the Borrower under Section 8.04, to the extent that the Issuing Bank is not promptly reimbursed for such costs and expenses by the Borrower. The failure of any Revolving Credit Lender to reimburse the Issuing Bank promptly upon demand for its Pro Rata Share of any amount required to be paid by the Revolving Credit Lenders to the Issuing Bank as provided herein shall not relieve any other Revolving Credit Lender of its obligation hereunder to reimburse the Issuing Bank for its Pro Rata Share of such amount, but no Revolving Credit Lender shall be responsible for the failure of any other Revolving Credit Lender to reimburse the Issuing Bank for such other Revolving Credit Lender’s Pro Rata Share of such amount. Without prejudice to the survival of any other agreement of any Revolving Credit Lender hereunder, the agreement and obligations of each Revolving Credit Lender contained in this Section 7.05(b) shall survive the payment in full of principal, interest and all other amounts payable hereunder and under the other Loan Documents.

SECTION 7.06. Non-Reliance on Agent and Other Lender Parties. Each Lender Party agrees that it has, independently and without reliance on any Agent or any other Lender Party, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Loan Parties and their Subsidiaries and decision to enter into this Agreement and that it will, independently and without reliance upon any Agent or any other Lender Party, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under the Loan Documents. Except for notices, reports, and other documents and information expressly required to be furnished to the Lender Parties by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender Party with any credit or other information concerning the affairs, financial condition, or business of any Loan Party or any of its Subsidiaries or Affiliates that may come into the possession of the Administrative Agent or any of its affiliates.

SECTION 7.07. Resignation of Administrative Agent. The Administrative Agent may resign at any time by giving notice thereof to the Lender Parties and the Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Administrative Agent. If no successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent’s giving of notice of resignation, then the retiring Administrative Agent may, on behalf of the Lender Parties, appoint a successor Administrative Agent which shall be a commercial bank organized under the laws of the United States of America or of any state thereof and having combined capital and surplus of at least $100,000,000. If within 30 days after written notice is given of the retiring Administrative Agent’s resignation under this Section 7.07 no successor Administrative Agent shall have been appointed and shall have accepted such appointment, then on such 30th day (a) the retiring Administrative Agent’s resignation shall become effective, (b) the retiring Administrative Agent shall thereupon be discharged from its duties and obligations under the Loan Documents and (c) the Required Lenders shall thereafter perform all duties and obligations of the retiring Administrative Agent under the Loan Documents until such time, if any, as the Required Lenders appoint a successor Administrative Agent as provided above in this Section 7.07. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor and upon the execution and filing or recording of such financing statements, or amendments thereto, and such other instruments or notices, as may be necessary or desirable, or as the Required Lenders may request, in order to continue the perfection of the Liens granted or purported to be granted by the Collateral Documents, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, discretion, privileges, and duties of the retiring Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations under the Loan Documents. After any retiring Agent’s resignation hereunder as Administrative Agent, the provisions of this Article VII shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Administrative Agent.

SECTION 7.08. Release of Collateral. Upon the payment of all Notes and all other amounts payable under the Loan Documents, the termination of all Letters of Credit and the termination of all commitments of the Lender Parties hereunder, the Lender Parties hereby agree that all Collateral is released from the security interest granted under the respective Collateral Documents, and upon (i) the sale, lease, transfer or other disposition of any item of Collateral of any Loan Party, (ii) the issuance or sale pursuant to Section 5.02(m)(iii) of any Equity Interests causing a Subsidiary of the Borrower to cease to be wholly-owned by the Borrower or any of its Subsidiaries, in each case in accordance with the terms of the Loan Documents, the Lender Parties hereby agree that such item of Collateral in the case of clause (i), or all Collateral owned by such Subsidiary in the case of clause (ii), shall be released from the security

interest granted under the respective Collateral Documents. In connection therewith, the Lender Parties hereby irrevocably authorize the Administrative Agent to release any such Collateral. The Administrative Agent will, at the Borrower’s expense, execute and deliver to the respective Loan Party such documents as such Loan Party may reasonably request to evidence the release of such item of Collateral from the security interest granted under the Collateral Documents.

SECTION 7.09. Release of Guarantor. Upon the sale of outstanding shares of capital stock and other equity, ownership and profit interests in any Guarantor in a transaction which is permitted under Section 5.02(e) and, if applicable, 5.02(m)(iii), then upon request by the Borrower, the Administrative Agent, on behalf of each Lender Party, shall confirm in writing that the liability of such Guarantor under the Subsidiary Guarantee is released and discharged effective when such transaction is consummated and all requirements hereunder in connection therewith are satisfied, including with respect to the application of the proceeds of such sale. Such confirmation from the Administrative Agent (a) shall establish conclusively that the liability of such Guarantor under the Subsidiary Guarantee is released and discharged and (b) may be relied on, without further inquiry, by the purchaser in such transaction and each of its transferees. Each Lender Party hereby irrevocably authorizes the Administrative Agent to release any Guarantor from time to time to the extent provided for herein and to execute any document reasonably required in connection therewith.

SECTION 7.10. Actions in Respect of Intercreditor Agreement. The Lenders and the Issuing Banks hereby authorize the Administrative Agent, in its capacity as Administrative Agent on behalf of the Lenders and the Issuing Banks, to enter into the Intercreditor Agreement and hereby consent to the Administrative Agent acting as Collateral Agent under the Intercreditor Agreement.

(b) The Borrower agrees to indemnify, defend and save and hold harmless each Agent, each Lender Party and each of their affiliates and their respective affiliates, officers, directors, trustees, employees, agents and advisors (each, an “Indemnified Party”) from and against, and shall pay on demand, any and all claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation or proceeding or preparation of a defense in connection therewith) (i) the Transaction (or any aspect thereof), Facilities, the actual or proposed use of the proceeds of the Advances or the Letters of Credit, the Loan Documents, or any of the transactions contemplated thereby; (ii) any acquisition or proposed acquisition by the Borrower or any of its Subsidiaries or Affiliates of all or any portion of the Equity Interests in or Debt securities or substantially all of the property and

In the case of an investigation, litigation or other proceeding to which the indemnity in this Section 8.04(b) applies, such indemnity shall be effective whether or not such investigation, litigation or proceeding is brought by any Loan Party, its directors, shareholders or creditors or an Indemnified Party or any other Person, whether or not any Indemnified Party is otherwise a party thereto and whether or not the Transaction or any of the other transactions contemplated hereby is consummated. If and to the extent that the indemnity in this subsection (b) is unenforceable for any reason other than by operation of the last clause of the first sentence of this subsection 8.04(b), the Borrower hereby agrees to make to each applicable Indemnified Party the maximum contribution to the payment of the claims, damages, losses, liabilities and expenses (including, without limitation, reasonable fees and expenses of counsel) for which the indemnity in this subsection (b) has been determined to be unenforceable that is permitted under applicable law. The Borrower also agrees not to assert any claim against any Agent, any Lender Party or any of their respective affiliates, officers, directors, trustees, employees, agents and advisors, on any theory of liability, for special, indirect, consequential or punitive damages arising out of or otherwise relating to the Transaction (or any aspect thereof) Facilities, the actual or proposed use of the proceeds of the Advances or the Letters of Credit, the Loan Documents, or any of the other transactions contemplated hereby.

(e) Without prejudice to the survival of any other agreement of any Loan Party hereunder or under any other Loan Document, the agreements and obligations of the Borrower contained in Sections 2.10 and 2.13 and this Section 8.04 shall survive the payment in full of principal, interest and all other amounts payable hereunder and under any of the other Loan Documents.

SECTION 8.05. Right of Set-off. Upon (a) the occurrence and during the continuance of any Event of Default and (b) the making of the request or the granting of the consent specified by Section 6.01 to authorize the Administrative Agent to declare the Notes due and payable pursuant to the provisions of Section 6.01, each Agent and each Lender Party and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and otherwise apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Agent, such Lender Party or such Affiliate to or for the credit or the account of the Borrower against any and all of the Obligations of the Borrower now or hereafter existing under the Loan Documents, irrespective of whether such Agent or such Lender Party shall have made any demand under this Agreement or such Note or Notes and although such Obligations may be unmatured. Each Agent and each Lender Party agrees promptly to notify the Borrower after any such set-off and application; provided, however, that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Agent and each Lender Party and their respective Affiliates under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) that such Agent, such Lender Party and their respective Affiliates may have.

SECTION 8.06. 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 each Lender Party and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with Section 8.07(a), (ii) by way of participation in accordance with Section 8.07(e), or (iii) by way of pledge or assignment of a security interest subject to the restrictions of Section 8.07(f) (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 Section 8.07(e) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lender Parties) any legal or equitable right, remedy or claim under or by reason of this Agreement.

SECTION 8.07. Assignments and Participations. (a) Any Lender may, and (b) so long as no Default under Section 6.01(a) or 6.01(f) or Event of Default has occurred and is continuing, if demanded by the Borrower (following (x) a demand by such Lender for the payment of additional compensation pursuant to Section 2.10(a), 2.10(b) or 2.13 or (y) an assertion by such Lender pursuant to Section 2.10(c) or 2.10(d) that it is impractical or unlawful for such Lender to make Eurodollar Rate Advances), upon at least five Business Days’ notice to such Lender and the Administrative Agent, each of the Lenders will, at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Commitment or Commitments, the Advances owing to it, the Note or Notes held by it and its participation in reimbursement obligations of the Borrower in respect of Letters of Credit); provided that:

(i) except in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment or Commitments, the Advances owing to it, the Note or Notes held by it, its participation in reimbursement obligations of the Borrower in respect of Letters of Credit or in the case of an assignment to a Lender or an Affiliate of a Lender or an Approved Fund with respect to a Lender, the aggregate amount of the Commitment (which for this purpose includes Advances outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Advance of the

assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $2,500,000, in the case of any assignment in respect of the Revolving Credit Facility, or $1,000,000, in the case of any assignment in respect of the Term Loan Facility;

(ii) each assignment shall require the consent of the Borrower (not to be unreasonably withheld or delayed), except for an assignment to a Lender, an Affiliate of a Lender or an Approved Fund or, if an Event of Default has occurred and is continuing, or if such assignment is made in connection with the syndication of the Revolving Credit Commitments or any Term Facility, any other assignee;

(iii) each assignment will require the consent of the Administrative Agent (not to be unreasonably withheld or delayed);

(iv) 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 Advance or the Commitment assigned, except that this clause (B) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Facilities on a non-pro rata basis;

(v) any assignment of a Revolving Credit Commitment must be approved by the Administrative Agent and the Issuing Bank unless the Person that is the proposed assignee is itself a Lender with a Revolving Credit Commitment (whether or not the proposed assignee would otherwise qualify as an Eligible Assignee);

(vi) the parties to each assignment shall (x) electronically execute and deliver to the Administrative Agent an Assignment and Assumption via an electronic settlement system acceptable to the Administrative Agent (which initially shall be Clearpar, LLC), together with any Note or Notes subject to such assignment, or (y) manually execute and deliver to the Administrative Agent an Assignment and Assumption, together with any Note or Notes subject to such assignment and, except in the case of an assignment by any of the Lenders to an Affiliate or an Approved Fund of such Lender, a processing and recordation fee of $3,500 (and in the case of simultaneous assignments on the same day by or to more than one fund managed or advised by the same investment advisor (which funds are not then Lenders hereunder), only a single $3,500 processing and recordation fee shall be payable for all such assignments), at the discretion of the Administrative Agent, and the Eligible Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire;

(vii) the Swing Line Bank may not assign or otherwise transfer to any other Person any of its rights or obligations under its Swing Line Commitment.

(viii) each such assignment made as a result of a demand by the Borrower pursuant to this Section 8.07(a)(ii) shall be arranged by the Borrower after consultation with the Administrative Agent and shall be either an assignment of all of the rights and obligations of the assigning Lender under this Agreement or an assignment of a portion of such rights and obligations made concurrently with another such assignment or other such assignments that together cover all of the rights and obligations of the assigning Lender under this Agreement.

(b) Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 8.07(c), from and after the effective date specified in each Assignment and Assumption, the Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender or the Issuing Bank under this Agreement, and the assigning Lender or Issuing Bank thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s or Issuing Bank’s rights and obligations under this Agreement, such Lender or Issuing Bank shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 2.10, 2.13 and 8.04 (and other similar provisions of the other Loan Documents to survive the payment in full of the Obligations of the Loan Parties under or in respect of the Loan Documents) 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 this Section 8.07(b).

(c) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at its office as set forth in Section 8.02, a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lender Parties, and the Commitments of, and principal amounts of the Advances 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 Lender Parties may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender Party hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Administrative Agent shall (i) upon the request by the Borrower or any Lender Party, provide a copy of the Register to the Borrower or such Lender Party, and (ii) upon its receipt of an Assignment and Assumption executed by an assigning Lender Party or Issuing Bank and an assignee, together with any Note or Notes subject to such assignment, if such Assignment and Assumption has been completed and is in substantially the form of Exhibit C hereto, (x) accept such Assignment and Assumption, and (y) record the information contained therein in the Register. In the case of any assignment by a Lender Party, the Borrower shall, at its own expense, and upon request by the Administrative Agent or any assignee, execute and deliver to the Administrative Agent in exchange for the surrendered Note or Notes a new Note or Notes from the Borrower payable to or to the order of such Eligible Assignee in an amount equal to the Commitment assumed by it under each Facility pursuant to such assignment and Assumption and, if the assigning Lender Party has retained a Commitment under such Facility, a new Note or Notes from the Borrower payable to or to the order of the assigning Lender Party in an amount equal to the Commitment retained by it under such Facility. Each of the new Note or Notes shall be in an aggregate principal amount equal to the aggregate principal amount of such surrendered Note or Notes, shall be dated the effective date of such Assignment and Assumption and shall otherwise be in substantially the form of Exhibit A-1, Exhibit A-2, Exhibit A-3 or Exhibit A-4 hereto, as appropriate.

(d) Any Lender Party 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 or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender Party’s rights and/or obligations under this Agreement (including all or a portion of its Commitment or Commitments, the Advances owing to it, the Note or Notes, if any, held by it and its participation, if any, in reimbursement obligations of the Borrower in respect of Letters of Credit); provided that:

(i) such Lender Party’s obligations under this Agreement shall remain unchanged,

(ii) such Lender Party shall remain solely responsible to the other parties hereto for the performance of such obligations and

(iii) the Borrower, the Administrative Agent and the other Lender Parties shall continue to deal solely and directly with such Lender Party in connection with such Lender Party’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender Party sells such a participation shall provide that such Lender Party 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 Party will not, without the consent of the Participant, agree to any amendment, modification or waiver described in Section 8.01(a) or (b) that affects such Participant. Subject to Section 8.07(e), the Borrower agrees that each Participant shall be entitled to the benefits of Sections 2.10, 2.13 and 8.04 to the same extent as if it were a Lender Party and had acquired its interest by assignment pursuant to Section 8.07(a). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 8.05 as though it were a Lender Party.

(e) A Participant shall not be entitled to receive any greater payment under Sections 2.10, 2.13 and 8.04 than the applicable Lender Party 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 party if it were a Lender Party shall not be entitled to the benefits of Section 2.13 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 2.13 as though it were a Lender Party.

(f) Any Lender Party 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 Party, 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 Party from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender Party as a party hereto. In the case of any Lender that is a fund that invests in bank loans, such Lender may, without the consent of the Borrower or Administrative Agent, assign or pledge all or any portion of its rights under this Agreement, including the Loans and Notes or any other instrument evidencing its rights as a Lender under this Agreement, to any holder of, trustee for, or any other representative of holders of, obligations owed or securities issued, by such fund, as security for such obligations or securities; provided that any foreclosure or similar action by such trustee or representative shall be subject to the provisions of this Section 8.07 concerning assignments.

(g) Notwithstanding anything to the contrary contained herein, any Lender Party (a “Granting Lender”) may grant to a special purpose funding vehicle identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower (an “SPC”) the option to provide all or any part of any Advance that such Granting Lender would otherwise be obligated to make pursuant to this Agreement, provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Advance, and (ii) if an SPC elects not to exercise such option or otherwise fails to make all or any part of such Advance, the Granting

Lender shall be obligated to make such Advance pursuant to the terms hereof. The making of an Advance by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Advance were made by such Granting Lender. Each party hereto hereby agrees that (i) no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender Party would be liable, (ii) no SPC shall be entitled to the benefits of Sections 2.10 and 2.13 (or any other increased costs protection provision) and (iii) the Granting Lender shall for all purposes, including, without limitation, the approval of any amendment or waiver of any provision of any Loan Document, remain the Lender Party of record hereunder. In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior Debt of any SPC, it will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency, or liquidation proceeding under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained in this Agreement, any SPC may (i) with notice to, but without prior consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or any portion of its interest in any Advance to the Granting Lender and (ii) disclose on a confidential basis any non-public information relating to its funding of Advances to any rating agency, commercial paper dealer or provider of any surety or guarantee or credit or liquidity enhancement to such SPC. This subsection (g) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Advances are being funded by the SPC at the time of such amendment.

(h) In the event that the Borrower shall request that the Lender Parties enter into any amendment, modification, consent or waiver with respect to this Agreement or any other Loan Document, and any Lender Party elects not to enter into such amendment, modification, consent or waiver (each such Lender Party being a “Dissenting Lender”), then the Borrower shall have the right upon 10 days’ written notice to the Administrative Agent and such Dissenting Lender, to require each such Dissenting Lender to assign 100% of the rights and obligations of the Dissenting Lender at par to any Lender or any other financial institution which satisfies the requirements of Section 8.07(a) and has been consented to by the Administrative Agent, the Swing Line Lender and in the case of any assignment of a Revolving Credit Commitment each Issuing Bank (which consents in the case of the Administrative Agent and the Swing Line Lender shall not be unreasonably withheld or delayed). Each such assignment shall be made pursuant to an Assignment and Assumption and shall comply with the other terms of this Section 8.07. The Borrower shall pay to such Dissenting Lender, concurrently with the effectiveness of such assignment, any amounts payable under this Agreement that would have been payable if the Borrower had voluntarily prepaid such Advances. The Dissenting Lender shall not be required to pay any fee relating to such assignment.

SECTION 8.08. Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery by telecopier of an executed counterpart of a signature page to this Agreement shall be effective as delivery of an original executed counterpart of this Agreement.

SECTION 8.09. No Liability of the Issuing Bank. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Bank nor any of its officers or directors shall be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement

100

thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by the Issuing Bank against presentation of documents that do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except that the Borrower shall have a claim against the Issuing Bank, and the Issuing Bank shall be liable to the Borrower, to the extent of any direct, but not consequential, damages suffered by the Borrower that the Borrower proves were caused by (i) the Issuing Bank’s willful misconduct or gross negligence, or failure to conform with the standards specified in Section 5-108 of the UCC, as determined in a final, non-appealable judgment by a court of competent jurisdiction in determining whether documents presented under any Letter of Credit comply with the terms of the Letter of Credit or (ii) the Issuing Bank’s willful failure to make lawful payment under a Letter of Credit after the presentation to it of a draft and certificates strictly complying with the terms and conditions of the Letter of Credit. In furtherance and not in limitation of the foregoing, but subject to Section 5-109(a) of the UCC, the Issuing Bank may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

SECTION 8.10. Confidentiality. Neither any Agent nor any Lender Party shall disclose any Confidential Information to any Person without the consent of the Borrower, other than (a) to such Agent’s or such Lender Party’s Affiliates and their officers, directors, employees, agents and advisors, to other Lender Parties and to actual or prospective Eligible Assignees and participants, and then only on a confidential basis, (b) as required by any law, rule or regulation or judicial process, (c) as requested or required by any state, Federal or foreign authority or examiner (including the National Association of Insurance Commissioners or any similar organization or quasi-regulatory authority) regulating such Lender Party, (d) to any rating agency when required by it, provided that, prior to any such disclosure, such rating agency shall undertake to preserve the confidentiality of any Confidential Information relating to the Loan Parties received by it from such Lender Party in accordance with such rating agency’s internal procedures generally applicable to information of the same type, (e) in connection with any litigation or proceeding to which such Agent or such Lender Party or any of its Affiliates may be a party, (f) in connection with the exercise of any remedy under this Agreement or any other Loan Document, or (g) to any direct or indirect contractual counterparty in swap agreements or such contractual counterparty’s professional advisor (so long as such contractual counterparty or professional advisor to such contractual counterparty agrees to be bound by the provisions of this Section 8.10). Notwithstanding anything herein to the contrary, each Loan Party, each Lender Party and the Administrative Agent and each of their respective officers, directors, employees, accountants, attorneys and other advisors, agents and representatives, may disclose to any and all persons, without limitation of any kind, any information with respect to the United States tax treatment and tax structure of the transactions contemplated by the Loan Documents and all materials of any kind (including opinions or other tax analyses) that are provided in respect to the respective Loan Party, Lender Party or the Administrative Agent, as the case may be, relating to such United States tax treatment and tax structure.

SECTION 8.11. Patriot Act Notice. Each of the Lender Parties hereby notifies each Loan Party that, pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies each Loan Party, which information includes names and addresses and other information that will allow it to identify each Loan Party in accordance with the Patriot Act.

Each of the parties hereto hereby 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 applicable law. Nothing in this Agreement shall affect any right that any of the parties hereto may otherwise have to bring any action or proceeding relating to this Agreement or any of the other Loan Documents in the courts of any jurisdiction.

(c) Each of the parties hereto irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection that it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents to which it is a party in any New York State or federal court. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.
