(b) The Borrowers may, upon at least three Business Days’ prior written notice (duly executed by a Responsible Officer of each Borrower) to the Administrative Agent (which shall promptly distribute copies thereof to the Lenders), terminate in whole or reduce ratably in part the unused portions of the Commitments; provided that any such partial reduction shall be in the aggregate amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof; and provided, further, that the Commitments shall in no event be reduced to an amount which is less than the aggregate LC Outstandings on the date of such reduction.

(c) In the event that, at any time, (i) all or a majority of the voting capital stock of any Borrower or Borrower Successor is sold, transferred or otherwise conveyed to any Person (other than a Wholly-Owned Subsidiary), (ii) all or substantially all of the assets of any Borrower or Borrower Successor are sold, transferred, leased or otherwise conveyed to any Person (other than a Wholly-Owned Subsidiary), or (iii) any Borrower or Borrower Successor no longer constitutes a Subsidiary, in each case as a result of or pursuant to a transaction (or series of transactions) permitted hereunder (including Section 8.02(b)) or otherwise, then (A) all Obligations of such Borrower or Borrower Successor (as the case may be) shall be immediately due and payable, (B) all outstanding Letters of Credit issued at the request and for the account of such Borrower or Borrower Successor (as the case may be) shall be cancelled, or such Borrower or Borrower Successor (as the case may be) shall pay immediately to the Administrative Agent an amount equal to the aggregate LC Outstandings of all such Letters of Credit, to be held by the Administrative Agent (for its benefit and the benefit of the Issuing Banks and the Lenders) as cash collateral securing such LC Outstandings and such Borrower’s or Borrower Successor’s (as the case may be) reimbursement obligations with respect thereto, (C) the Commitments shall be automatically and permanently reduced by an amount equal to the excess (if any) of (1) the aggregate amount of the Commitments at such time over (2) $45,000,000, (D) such Borrower or Borrower Successor (as the case may be) shall no longer be permitted to request or receive any Extension of Credit and (E) upon the payment in full of all outstanding Obligations of such Borrower or Borrower Successor (as the case may be) and the satisfaction of the requirements set forth in clause (B) above, such Borrower or Borrower Successor (as the case may be) shall automatically and immediately cease to be a party to this Agreement; provided, however, that this paragraph (c) shall not apply to any transaction described in clause (i), (ii) or (iii) above with respect to any Borrower if (x) the Commitments have previously been reduced pursuant to clause (C) above, (y) such Borrower is the only borrower under this Agreement and (z) in connection with such transaction, both a Guarantor Successor and a Borrower Successor have assumed all obligations of the Guarantor (if any) and such Borrower, respectively, under this Agreement and

the other Loan Documents in accordance with Section 8.02(b)(i)(D), and the other conditions set forth in Section 8.02(b)(i)(A) through (E) have been satisfied.

SECTION 2.04. Computations of Outstandings. Whenever reference is made in this Agreement to the principal amount outstanding on any date under this Agreement, such reference shall refer to the sum of (a) the aggregate principal amount of all Loans outstanding on such date plus (b) the aggregate LC Outstandings of all Letters of Credit outstanding on such date, in each case after giving effect to all Extensions of Credit to be made on such date and the application of the proceeds thereof. At no time shall the principal amount outstanding under this Agreement exceed (i) until the date on which the conditions set forth in Section 6.02(b) shall have been satisfied, $40,000,000 or (ii) the aggregate amount of the Commitments, and at no time shall the portion of the principal amount outstanding under this Agreement attributed to any Borrower exceed such Borrower’s Availability Sublimit. References to the unused portion of the Commitments shall refer to the excess, if any, of the Commitments over the principal amount outstanding hereunder; and references to the unused portion of any Lender’s Commitment shall refer to such Lender’s Percentage of the unused Commitments.

ARTICLE III

LOANS

SECTION 3.01. Loans. (a) Each Borrower may request a Borrowing (other than a Conversion) by delivering a notice (a “Notice of Borrowing”) to the Administrative Agent no later than 11:00 A.M. on the third Business Day or, in the case of ABR Loans, on the first Business Day, prior to the date of the proposed Borrowing. The Administrative Agent shall give each Lender prompt notice of each Notice of Borrowing. Each Notice of Borrowing shall be in substantially the form of Exhibit A and shall specify the requested (i) date of such Borrowing (which shall be a Business Day, but in no event later than the Business Day immediately preceding the Revolving Credit Termination Date), (ii) Type of Loans to be made in connection with such Borrowing, (iii) Interest Period, if any, for such Loans and (iv) amount of such Borrowing. Each proposed Borrowing shall conform to the requirements of Sections 3.03 and 3.04.

(b) Each Lender shall, before 10:00 A.M. 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 address referred to in Section 12.02, in same day funds, such Lender’s Percentage of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article VI, the Administrative Agent will make such funds available to the applicable Borrower at the Administrative Agent’s aforesaid address. Notwithstanding the foregoing, unless the Administrative Agent shall have received notice from a Lender prior to the date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Percentage of such Borrowing, the Administrative Agent may assume that such Lender has made such Percentage available to the Administrative Agent on the date of such Borrowing in accordance with the first sentence of this subsection (b), and the Administrative Agent may, in reliance upon such assumption, make available to the applicable Borrower on such date a corresponding amount.

(c) If and to the extent that any Lender (a “non-performing Lender”) shall not have made available to the Administrative Agent, in accordance with subsection (b) above, such Lender’s Percentage of any Borrowing, the non-performing Lender and the applicable Borrower severally agree to repay to the Administrative Agent forthwith on demand corresponding amounts (not to exceed the aggregate amount that such non-performing Lender failed to make available to the Administrative Agent), together with interest thereon for each day from the date such amount is made available to such Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of such Borrower, the interest rate applicable at the time to Loans made in connection with such Borrowing and (ii) in the case of such Lender, the Federal Funds Effective Rate. Within the limits of each Lender’s Available Commitment and subject to the other terms and conditions set forth in this Agreement for the making of Loans, each Borrower may request (and the Lenders shall honor) one or more additional Borrowings from the performing Lenders to fund such repayment to the Administrative Agent. If a non-performing Lender shall repay to the Administrative Agent such corresponding amount in full (with interest as above provided), (x) the Administrative Agent shall apply such corresponding amount and interest to the repayment to the Administrative Agent (or repayment of Loans made to fund such repayment to the Administrative Agent), and shall make any remainder available to the applicable Borrower and (y) such amount so repaid shall be deemed to constitute such Lender’s Loan, made as part of such Borrowing for purposes of this Agreement as if funded concurrently with the other Loans made as part of such Borrowing, and such Lender shall forthwith cease to be deemed a non-performing Lender; if and so long as such non-performing Lender shall not repay such amount, and unless and until an Eligible Assignee shall have assumed and performed the obligations of such non-performing Lender, all computations by the Administrative Agent of Percentages, Commitments and payments hereunder shall be made without regard to the Commitments, or outstanding Loans, of such non-performing Lender, and any amounts paid to the Administrative Agent for the account of such non-performing Lender shall be held by the Administrative Agent in trust for such non-performing Lender in a non-interest-bearing special purpose account. Nothing herein shall in any way limit, waive or otherwise reduce any claims that any party hereto may have against any non-performing Lender. The failure of any Lender to make the Loan 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 Loan on the date of such Borrowing, but no Lender shall be responsible for the failure of any other Lender to make the Loan to be made by such other Lender on the date of any Borrowing.

(d) Any Lender may request that Loans made by it hereunder be evidenced by a Promissory Note. In such event, the Borrowers shall prepare, execute and deliver to such Lender a Promissory Note payable to the order of such Lender (or, if requested by such Lender, to such Lender and its registered assigns) and in a form approved by the Administrative Agent. Thereafter, the Loans evidenced by such Promissory Note and interest thereon shall at all times (including after assignment pursuant to Section 12.07) be represented by one or more Promissory Notes in such form payable to the order of the payee named therein (or, if such Promissory Note is a registered note, to such payee and its registered assigns).

SECTION 3.02. Conversion of Loans. Each Borrower may from time to time Convert any Loan (or portion thereof) of any Type made to such Borrower to one or more Loans of the same or any other Type by delivering a notice of such Conversion (a “Notice of Conversion”) to the Administrative Agent no later than 11:00 A.M. on (x) the third Business Day prior to the date

of any proposed Conversion into a Eurodollar Rate Loan and (y) the first Business Day prior to the date of any proposed Conversion into an ABR Loan. The Administrative Agent shall give each Lender prompt notice of each Notice of Conversion. Each Notice of Conversion shall be in substantially the form of Exhibit B and shall specify (i) the requested date of such Conversion (which shall be a Business Day), (ii) the Type of, and Interest Period, if any, applicable to, the Loans (or portions thereof) proposed to be Converted, (iii) the requested Type of Loans to which such Loans (or portions thereof) are proposed to be Converted, (iv) the requested initial Interest Period, if any, to be applicable to the Loans resulting from such Conversion and (v) the aggregate amount of Loans (or portions thereof) proposed to be Converted. Each proposed Conversion shall be subject to the provisions of Sections 3.03 and 3.04.

SECTION 3.03. Interest Periods. The period between the date of each Eurodollar Rate Loan and the date of payment in full of such Loan shall be divided into successive periods (“Interest Periods”) for purposes of computing interest applicable thereto. The initial Interest Period for each such Loan shall begin on the day such Loan is made, and each subsequent Interest Period shall begin on the last day of the immediately preceding Interest Period for such Loan. The duration of each Interest Period shall be one, two, three or six months, as the applicable Borrower may, in accordance with Section 3.01 or 3.02, select; provided, however, that:

(i) a Borrower may not select any Interest Period that ends after the Revolving Credit Termination Date;

(ii) whenever the last day of any Interest Period would otherwise occur on a day other than a Business Day, the last day of such Interest Period shall occur on the next succeeding Business Day, provided that if such extension would cause the last day of such Interest Period to occur in the next following calendar month, the last day of such Interest Period shall occur on the next preceding Business Day; and

(iii) any Interest Period that commences on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the last calendar month of such Interest Period) shall end on the last Business Day of the last calendar month of such Interest Period.

SECTION 3.04. Other Terms Relating to the Making and Conversion of Loans. (a) Notwithstanding anything in Section 3.01 or 3.02 to the contrary:

(i) each Borrowing (other than a Borrowing deemed made under Section 4.04(c) or (d)) shall be in an aggregate amount not less than $1,000,000 or an integral multiple of $1,000,000 in excess thereof (or, in each case, such lesser amount as shall be equal to the total amount of the Available Commitments on such date, after giving effect to all other Extensions of Credit to be made on such date), and shall consist of Loans of the same Type, having the same Interest Period and made or Converted on the same day by the Lenders ratably according to their respective Percentages;

(ii) a Borrower may request that more than one Borrowing be made on the same day;

(iii) at no time shall more than eight (8) different Borrowings comprising Eurodollar Rate Loans be outstanding hereunder;

(iv) no Eurodollar Rate Loan may be Converted on a date other than the last day of the Interest Period applicable to such Loan unless the corresponding amounts, if any, payable to the Lenders pursuant to Section 5.04(b) are paid contemporaneously with such Conversion;

(v) if a Borrower shall either fail to give a timely Notice of Conversion pursuant to Section 3.02 in respect of any Loans made to such Borrower or fail, in any Notice of Conversion that has been timely given by such Borrower, to select the duration of any Interest Period for Loans to be Converted into Eurodollar Rate Loans in accordance with Section 3.03, such Loans shall, on the last day of the then existing Interest Period therefor, automatically Convert into, or remain as, as the case may be, ABR Loans; and

(vi) if an Event of Default has occurred and is continuing with respect to any Borrower or, prior to the occurrence of the Guaranty Termination Date with respect to such Borrower, the Guarantor, (A) no outstanding Loans made to such Borrower may be Converted to or continued as Eurodollar Rate Loans and (B) unless repaid, each Eurodollar Rate Loan made to such Borrower shall be Converted to an ABR Loan at the end of the Interest Period applicable thereto.

(b) If any Lender shall notify the Administrative Agent that the introduction of or any change in, or in the interpretation of, any law or regulation makes it unlawful, or that any central bank or other Governmental Authority asserts that it is unlawful, for such Lender or its Applicable Lending Office to perform its obligations hereunder to make, or to fund or maintain, Eurodollar Rate Loans hereunder, (i) the obligation of such Lender to make, or to Convert Loans into, Eurodollar Rate Loans for any Borrowing from such Lender shall be forthwith suspended until the earlier to occur of the date upon which (A) such Lender shall cease to be a party hereto and (B) it is no longer unlawful for such Lender to make, fund or maintain Eurodollar Rate Loans, and (ii) if the maintenance of Eurodollar Rate Loans then outstanding through the last day of the Interest Period therefor would cause such Lender to be in violation of such law, regulation or assertion, such Lender may require each Borrower to either prepay or Convert all Eurodollar Rate Loans made by such Lender to such Borrower within five days after such Borrower’s receipt of such notice, and if such Borrower shall not have so prepaid or Converted such Eurodollar Rate Loans by such fifth day, then such Eurodollar Rate Loans shall be deemed automatically Converted to ABR Loans on such fifth day. Promptly upon becoming aware that the circumstances that caused such Lender to deliver such notice no longer exist, such Lender shall deliver notice thereof to the Administrative Agent (but the failure to do so shall impose no liability upon such Lender). Promptly upon receipt of such notice from such Lender (or upon such Lender’s assigning all of its Commitments, Loans, participation and other rights and obligations hereunder to an Eligible Assignee), the Administrative Agent shall deliver notice thereof to the Borrowers and the Lenders and such suspension shall terminate.

(c) If the Required Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate for Eurodollar Rate Loans to be made in connection with such Borrowing will not adequately reflect the cost to such Required Lenders of making, funding or maintaining their respective Eurodollar Rate Loans for such Borrowing, the right of the Borrowers to select Eurodollar Rate Loans for such Borrowing and any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrowers and the Lenders that the circumstances causing such suspension no longer exist, and each Loan to be made or Converted in connection with such Borrowing shall be an ABR Loan.

(d) If any Lender shall have delivered a notice to any Borrower or the Administrative Agent described in Section 3.04(b) or Section 3.06, or shall become a non-performing Lender under Section 3.01(c) or Section 4.04(c), and if and so long as such Lender shall not have withdrawn such notice or corrected such non-performance in accordance with said Section 3.04(b), Section 3.06, Section 3.01(c) or Section 4.04(c), the Borrowers or the Administrative Agent may demand that such Lender assign in accordance with Section 12.07, to one or more Eligible Assignees designated by the Borrowers or the Administrative Agent, all (but not less than all) of such Lender’s Commitments, Loans, participation and other rights and obligations hereunder; provided that any such demand by the Borrowers during the continuance of a Default or an Event of Default shall be ineffective without the consent of the Required Lenders. If, within 30 days following any such demand by the Administrative Agent or the Borrowers, any such Eligible Assignee so designated shall fail to consummate such assignment on terms reasonably satisfactory to such Lender, or the Borrowers and the Administrative Agent shall have failed to designate any such Eligible Assignee, then such demand by the Borrowers or the Administrative Agent shall become ineffective, it being understood for purposes of this provision that such assignment shall be conclusively deemed to be on terms reasonably satisfactory to such Lender, and such Lender shall be compelled to consummate such assignment forthwith, if such Eligible Assignee (i) shall agree to such assignment in substantially the form of the Lender Assignment attached hereto as Exhibit E and (ii) shall tender payment to such Lender in an amount equal to the full outstanding Dollar amount accrued in favor of such Lender hereunder (as computed in accordance with the records of the Administrative Agent), including, without limitation, all accrued interest and fees and, to the extent not paid by the Borrowers, any payments required pursuant to Section 5.04(b).

(e) Each Notice of Borrowing and Notice of Conversion shall be irrevocable and binding on the applicable Borrower. In the case of any Borrowing which the related Notice of Borrowing or Notice of Conversion specifies is to be comprised of Eurodollar Rate Loans, the applicable Borrower shall severally indemnify each Lender against any loss, cost or expense incurred by such Lender as a result of any failure by such Borrower to fulfill, on or before the date specified in such Notice of Borrowing or Notice of Conversion for such Borrowing, the applicable conditions (if any) set forth in this Article III (other than failure pursuant to the provisions of Section 3.04(c) hereof) or in Article VI, including any such loss (including loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Loan to be made by such Lender when such Loan, as a result of such failure, is not made on such date.

SECTION 3.05. Repayment of Loans; Interest.

(a) Principal. Each Borrower shall repay in full, on the Revolving Credit Termination Date, the outstanding principal amount of the Loans made to such Borrower.

(b) Interest. Each Borrower shall pay interest on the unpaid principal amount of each Loan made to such Borrower from the date of such Loan until such principal amount shall be paid in full, at the Applicable Rate for such Loan, payable as follows:

(i) ABR Loans. If such Loan is an ABR Loan, interest thereon shall be payable quarterly in arrears on the last day of each March, June, September and December, on the date of any Conversion of such ABR Loan and on the date such ABR Loan shall become due and payable or shall otherwise be paid in full; provided, however, that interest accruing on the principal amount of any ABR Loan that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall be payable on demand.

(ii) Eurodollar Rate Loans. If such Loan is a Eurodollar Rate Loan, interest thereon shall be payable on the last day of each Interest Period for such Loan and, if the Interest Period for such Loan has a duration of more than three months, on that day of each third month during such Interest Period that corresponds to the first day of such Interest Period (or, if any such month does not have a corresponding day, then on the last day of such month); provided, however, that interest accruing on the principal amount of any Eurodollar Rate Loan that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall be payable on demand.

SECTION 3.06. Additional Interest on Eurodollar Rate Loans. Each Borrower shall pay to the Administrative Agent for the account of each Lender any costs actually incurred by such Lender with respect to Eurodollar Rate Loans made to such Borrower that are attributable to such Lender’s compliance with regulations of the Board requiring the maintenance of reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities. Such costs shall be paid to the Administrative Agent for the account of such Lender in the form of additional interest on the unpaid principal amount of each Eurodollar Rate Loan of such Lender made to such Borrower, from the date of such Eurodollar Rate Loan until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Eurodollar Rate Loan from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Eurodollar Rate Loan (but in no event earlier than five Business Days after the Borrower’s receipt of the certificate referred to in the last sentence of this Section 3.06). Such additional interest shall be determined by such Lender and notified to the applicable Borrower through the Administrative Agent. A certificate as to the amount of such additional interest and giving a reasonable explanation and calculation thereof shall be submitted to the applicable Borrower and the Administrative Agent by such Lender and shall be conclusive and binding for all purposes, absent manifest error.

SECTION 3.07. New Lenders. On the Closing Date, each New Lender and Increasing Lender (as hereinafter defined) shall purchase by assignment from the Existing

Lenders such portion of the Loans (if any) owing to them as shall be designated by the Administrative Agent such that, after giving effect to all such purchases and assignments, the outstanding Loans owing to each Lender shall equal such Lender’s Percentage of the aggregate amount of Loans owing to all Lenders. As used herein, the term “Increasing Lender” means each Existing Lender whose Commitment (as set forth on the signature pages hereof) exceeds its Commitment (as defined in the Existing Credit Agreement) under the Existing Credit Agreement.

ARTICLE IV

LETTERS OF CREDIT

SECTION 4.01. Issuing Banks. Subject to the terms and conditions hereof, each Borrower may from time to time identify and arrange for one or more Lenders to act as Issuing Banks hereunder. Notice of any such designation by a Borrower shall be given to the Administrative Agent at least four Business Days prior to the first date upon which such Borrower proposes that such Issuing Bank issue its first Letter of Credit, so as to provide adequate time for such proposed Issuing Bank to be approved by the Administrative Agent hereunder (such approval not to be unreasonably withheld). Within two Business Days following the receipt of any such designation of a proposed Issuing Bank, the Administrative Agent shall notify the applicable Borrower as to whether such designee is acceptable to the Administrative Agent. Nothing contained herein shall be deemed to require any Lender to agree to act as an Issuing Bank, if it does not so desire.

SECTION 4.02. Letters of Credit. (a) Each Letter of Credit shall be issued (or the stated maturity thereof extended or terms thereof modified or amended) on not less than three Business Days’ prior written notice thereof to the Administrative Agent (which shall promptly distribute copies thereof to the Lenders) and the relevant Issuing Bank. Each such notice (a “Request for Issuance”) shall specify (i) the date (which shall be a Business Day, but in no event later than the date that occurs ten (10) Business Days prior to the Revolving Credit Termination Date) of issuance of such Letter of Credit (or the date of effectiveness of such extension, modification or amendment) and the stated expiry date thereof (which shall be no later than the date that occurs one year from the date of issuance of such Letter of Credit (or, in the case of any extension of a Letter of Credit, one year from the date of effectiveness of such extension), and in any event no later than the Letter of Credit Expiration Date, (ii) the proposed stated amount of such Letter of Credit (which shall not be less than $250,000) and (iii) such other information as shall demonstrate compliance of such Letter of Credit with the requirements specified therefor in this Agreement and the relevant Issuing Bank Agreement. Each Request for Issuance shall be irrevocable unless modified or rescinded by the applicable Borrower not less than one Business Day prior to the proposed date of issuance (or effectiveness) specified therein. Not later than 10:00 A.M. on the proposed date of issuance (or effectiveness) specified in such Request for Issuance, and upon fulfillment of the applicable conditions precedent and the other requirements set forth herein and in the relevant Issuing Bank Agreement, such Issuing Bank shall issue (or extend, amend or modify) such Letter of Credit and provide notice and a copy thereof to the Administrative Agent, which shall promptly furnish copies thereof to the Lenders.

(b) Each Lender severally agrees with such Issuing Bank to participate in the Extension of Credit resulting from the issuance (or extension, modification or amendment) of such Letter of Credit, in the manner and the amount provided in Section 4.04(b), and the issuance of such Letter of Credit shall be deemed to be a confirmation by such Issuing Bank and each Lender of such participation in such amount.

(c) Notwithstanding anything herein to the contrary, the aggregate LC Outstandings of all Letters of Credit outstanding at any one time shall not exceed the Letter of Credit Sublimit.

SECTION 4.03. Issuing Bank Fees Each Borrower shall pay directly to each Issuing Bank such fees and expenses, if any, specified to be paid by it to such Issuing Bank pursuant to the Issuing Bank Agreement to which such Borrower and such Issuing Bank are parties, at the times, and in the manner, specified in such Issuing Bank Agreement.

SECTION 4.04. Reimbursement to Issuing Banks. (a) Each Borrower hereby agrees to pay to the Administrative Agent for the account of each Issuing Bank, on demand made by such Issuing Bank to such Borrower and the Administrative Agent, on and after each date on which such Issuing Bank shall pay any amount under any Letter of Credit issued by such Issuing Bank at the request of such Borrower, a sum equal to the amount so paid plus interest on such amount from the date so paid by such Issuing Bank until repayment to such Issuing Bank in full at a fluctuating interest rate per annum equal at all times to the Applicable Rate for ABR Loans.

(b) If any Issuing Bank shall not have been reimbursed in full for any payment made by such Issuing Bank under any Letter of Credit issued by such Issuing Bank on the date of such payment, such Issuing Bank shall give the Administrative Agent and each Lender prompt notice thereof (an “LC Payment Notice”) no later than 10:00 A.M. on the Business Day immediately succeeding the date of such payment by such Issuing Bank. Each Lender severally agrees to purchase a participation in the reimbursement obligation of the applicable Borrower to such Issuing Bank under subsection (a) above, by paying to the Administrative Agent for the account of such Issuing Bank an amount equal to such Lender’s Percentage of such unreimbursed amount paid by such Issuing Bank, plus interest on such amount at a rate per annum equal to the Federal Funds Effective Rate from the date of such payment by such Issuing Bank to the date of payment to such Issuing Bank by such Lender. Each such payment by a Lender shall be made not later than 1:00 P.M. on the later to occur of (i) the Business Day immediately following the date of such payment by such Issuing Bank and (ii) the Business Day on which such Lender shall have received an LC Payment Notice from such Issuing Bank. Each Lender’s obligation to make each such payment to the Administrative Agent for the account of such Issuing Bank shall be several and shall not be affected by (A) the occurrence or continuance of any Default or Event of Default, (B) the failure of any other Lender to make any payment under this Section 4.04, or (C) the date of the drawing under the applicable Letter of Credit issued by such Issuing Bank. Each Lender further agrees that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(c) The failure of any Lender to make any payment to the Administrative Agent for the account of an Issuing Bank in accordance with subsection (b) above shall not relieve any other Lender of its obligation to make payment, but no Lender shall be responsible for the failure of any other Lender. If any Lender (a “non-performing Lender”) shall fail to make any payment

to the Administrative Agent for the account of an Issuing Bank in accordance with subsection (b) above within five Business Days after such Lender’s receipt of the LC Payment Notice relating thereto, then, for so long as such failure shall continue, such Issuing Bank shall be deemed, for purposes of Section 5.05 and Article IX hereof, to be a Lender hereunder owed a Loan in an amount equal to the outstanding principal amount due and payable by such Lender to the Administrative Agent for the account of such Issuing Bank pursuant to subsection (b) above.

(d) Each participation purchased by a Lender under subsection (b) above shall constitute an ABR Loan deemed made by such Lender to the applicable Borrower on the date of such payment by the relevant Issuing Bank under the applicable Letter of Credit issued by such Issuing Bank at the request of such Borrower (irrespective of such Borrower’s noncompliance, if any, with the conditions precedent for Loans hereunder); and all such payments by the Lenders in respect of any one such payment by such Issuing Bank shall constitute a single Borrowing hereunder.

SECTION 4.05. Obligations Absolute. The payment obligations of each Lender under Section 4.04(b) and of each Borrower under this Agreement in respect of any payment under any Letter of Credit and any Loan deemed made under Section 4.04(c) or (d) shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, including the following circumstances:

(i) any lack of validity or enforceability of any Loan Document or any other agreement or instrument relating thereto or to such Letter of Credit;

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

(iii) the existence of any claim, set-off, defense or other right which any Borrower may have at any time against any beneficiary, or any transferee, of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), any Issuing Bank, or any other Person, whether in connection with this Agreement, the transactions contemplated herein or by such Letter of Credit, or any unrelated transaction;

(iv) any statement or any other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect;

(v) payment in good faith by any Issuing Bank under any Letter of Credit issued by such Issuing Bank against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

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

SECTION 4.06. Liability of Issuing Banks and the Lenders. Each Borrower assumes all risks of the acts and omissions of any beneficiary or transferee of any Letter of Credit issued at the request of such Borrower in connection with such Letter of Credit, and neither the Issuing

Bank that has issued such Letter of Credit, the Lenders nor any of their respective officers, directors, employees, agents or Affiliates shall be liable or responsible for (a) the use that may be made of such Letter of Credit or any acts or omissions of any beneficiary or transferee thereof in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by such Issuing Bank against presentation of documents that do not comply with the terms of such Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under such Letter of Credit, except that the applicable Borrower shall have the right to bring suit against such Issuing Bank, and such Issuing Bank shall be liable to such Borrower and any Lender, to the extent of any direct, as opposed to consequential, damages suffered by such Borrower or such Lender which such Borrower or such Lender proves were caused by such Issuing Bank’s willful misconduct or gross negligence, including such Issuing Bank’s willful failure to make timely payment under such Letter of Credit following the presentation to it by the beneficiary thereof of a draft and accompanying certificate(s) which strictly comply with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, any Issuing Bank may accept sight drafts and accompanying certificates presented under any Letter of Credit issued by such Issuing Bank that appear on their face to be in order, without responsibility for further investigation. Notwithstanding the foregoing, no Lender shall be obligated to indemnify any Borrower for damages caused by any Issuing Bank’s willful misconduct or gross negligence, and the obligation of each Borrower to reimburse the Lenders hereunder in accordance with the terms hereof shall be absolute and unconditional, notwithstanding the gross negligence or willful misconduct of any Issuing Bank.

ARTICLE V

PAYMENTS, COMPUTATIONS AND

YIELD PROTECTION

SECTION 5.01. Payments and Computations. (a) The Borrowers shall make each payment hereunder and under the other Loan Documents not later than 10:00 A.M. on the day when due in Dollars to the Administrative Agent at its address referred to in Section 12.02 in same day funds, except payments to be made directly to any Issuing Bank as expressly provided herein; any payment received after 10:00 A.M. shall be deemed to have been received at the start of business on the next succeeding Business Day. The Administrative Agent will promptly thereafter cause to be distributed like funds relating to the payment of principal, interest, fees or other amounts payable to the Lenders, to the respective Lenders to which the same are payable, for the account of their respective Applicable Lending Offices, in each case to be applied in accordance with the terms of this Agreement. If and to the extent that any distribution of any payment from a Borrower required to be made to any Lender pursuant to the preceding sentence shall not be made in full by the Administrative Agent on the date such payment was received by the Administrative Agent, the Administrative Agent shall pay to such Lender, upon demand, interest on the unpaid amount of such distribution, at a rate per annum equal to the Federal Funds Effective Rate, from the date of such payment by such Borrower to the Administrative Agent to the date of payment in full by the Administrative Agent to such Lender of such unpaid amount. Upon the Administrative Agent’s acceptance of a Lender Assignment and recording of the

information contained therein in the Register pursuant to Section 12.07, from and after the effective date specified in such Lender Assignment, the Administrative Agent shall make all payments hereunder and under any Promissory Notes in respect of the interest assigned thereby to the Lender assignee thereunder, and the parties to such Lender Assignment shall make all appropriate adjustments in such payments for periods prior to such effective date directly between themselves.

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

(c) All computations of interest based on the Alternate Base Rate (when the Alternate Base Rate is based on the Reference Rate) shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be. All other computations of interest and fees hereunder (including computations of interest based on the Eurodollar Rate and the Federal Funds Effective Rate) shall be made by the Administrative Agent on the basis of a year of 360 days. In each such case, such computation shall be made for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or fees are payable. Each such determination by the Administrative Agent or a Lender shall be conclusive and binding for all purposes, absent manifest error.

(d) Whenever any payment hereunder or under any other Loan Document 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 and fees hereunder; provided, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(e) Unless the Administrative Agent shall have received notice from a Borrower prior to the date on which any payment by such Borrower is due to the Lenders hereunder that such Borrower will not make such payment in full, the Administrative Agent may assume that such Borrower has made such payment in full to the Administrative Agent on such date, and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such due date an amount equal to the amount then due by such Borrower to such Lender. If and to the extent such Borrower shall not have so made such payment in full to the Administrative Agent, such Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest thereon, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Effective Rate.

(f) Any fees, interest, costs, expenses or other amount (other than the principal amount of any Loan, which shall accrue interest at the Applicable Rate for such Loan) payable by the Borrower hereunder or under any of the Promissory Notes that is not paid when due (whether at stated maturity, by acceleration or otherwise) shall (to the fullest extent permitted by

law) bear interest, from the date when due until paid in full, at a rate per annum equal at all times to the Default Rate, payable on demand.

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

SECTION 5.02. Interest Rate Determination. The Administrative Agent shall give prompt notice to the applicable Borrower and the Lenders of the interest rate determined by the Administrative Agent for purposes of Section 3.05(b)(i) or (ii) applicable to Loans made to such Borrower.

SECTION 5.03. Prepayments No Borrower shall have any right to prepay any principal amount of any Loans made to such Borrower other than as provided in subsections (a) and (b) below.

(a) Each Borrower may, upon at least three Business Days’ written notice, with respect to Eurodollar Rate Loans, and one Business Day’s written notice, with respect to ABR Loans, to the Administrative Agent stating the proposed date and the aggregate principal amount of the prepayment, and if such notice is given such Borrower shall, prepay the outstanding principal amounts of Loans made to such Borrower as part of the same Borrowing, in whole or ratably in part, together with (i) accrued interest to the date of such prepayment on the principal amount prepaid and (ii) in the case of Eurodollar Rate Loans, any amount payable to the Lenders pursuant to Section 5.04(b); provided, however, that each partial prepayment shall be in an aggregate principal amount of not less than $1,000,000 or an integral multiple of $1,000,000 in excess thereof.

(b) On the date of any termination or reduction of the Commitments pursuant to Section 2.03, the Borrowers shall pay or prepay so much of the principal amount outstanding hereunder as shall be necessary in order that the aggregate principal amount outstanding hereunder (after giving effect to all Extensions of Credit to be made on such date and the application of the proceeds thereof) will not exceed the Commitments (and, with respect to each Borrower, such Borrower’s Availability Sublimit) following such termination or reduction, together with (i) accrued interest to the date of such prepayment on the principal amount prepaid and (ii) in the case of prepayments of Eurodollar Rate Loans, any amount payable to the Lenders pursuant to Section 5.04(b). In connection with any partial reduction of the Commitments pursuant to Section 2.03(b), the Borrowers shall designate, in the written notice delivered to the Administrative Agent pursuant to Section 2.03(b), which outstanding Borrowings will be prepaid pursuant to this subsection (b) on the date of such reduction; provided, that if the Borrowers fail to provide such designation, the prepayments required by this subsection (b) shall be applied (A) on a pro rata basis to the outstanding Borrowings of each Borrower, and (B) to outstanding ABR Loans up to the full amount thereof before they are applied to outstanding Eurodollar Rate Loans

(in the order of the remaining duration of their respective Interest Periods (the Eurodollar Rate Loans with the shortest remaining Interest Period to be prepaid first)).

SECTION 5.04. Yield Protection.

(a) Increased Costs. If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation after the date hereof, or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law) issued or made after the date hereof, there shall be reasonably incurred any increase in (A) the cost to any Lender of agreeing to make or making, funding or maintaining Eurodollar Rate Loans, or of participating in the issuance, maintenance or funding of any Letter of Credit, or (B) the cost to any Issuing Bank of issuing or maintaining any Letter of Credit, then the Borrowers shall from time to time, promptly after receipt of written demand by such Lender or Issuing Bank, as the case may be (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender or Issuing Bank, as the case may be, additional amounts sufficient to compensate such Lender or Issuing Bank, as the case may be, for such increased cost. A certificate as to the amount of such increased cost and giving a reasonable explanation and calculation thereof shall be submitted to the Borrowers and the Administrative Agent by such Lender or such Issuing Bank, as the case may be, shall constitute such demand and shall be conclusive and binding for all purposes, absent manifest error.

(b) Breakage. If, due to any prepayment pursuant to Section 5.03, an acceleration of maturity of the Loans pursuant to Section 9.02, or any other reason, any Lender receives payments of principal of any Eurodollar Rate Loan made to any Borrower other than on the last day of the Interest Period relating to such Loan, or if any Borrower shall Convert any Eurodollar Rate Loans on any day other than the last day of the Interest Period therefor, such Borrower shall, promptly after demand by such Lender (with a copy of such demand to the Administrative Agent), pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for additional losses, costs, or expenses (including anticipated lost profits) that such Lender may reasonably incur as a result of such payment or Conversion, including any loss, cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain such Loan. For purposes of this subsection (b) and Section 3.04(e), a certificate setting forth the amount of such additional losses, costs, or expenses and giving a reasonable explanation and calculation thereof shall be submitted to the applicable Borrower and the Administrative Agent by such Lender, shall constitute such demand and shall be conclusive and binding for all purposes, absent manifest error.

(c) Capital. If any Lender or Issuing Bank determines that (i) the introduction of or any change in or in the interpretation of any law or regulation after the date hereof or (ii) compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) issued or made after the date hereof, affects or would affect the amount of capital required or expected to be maintained by such Lender or Issuing Bank, whether directly, or indirectly as a result of commitments of any corporation controlling such Lender or Issuing Bank (but without duplication), and the amount of such capital is increased by or based upon (A) the existence of such Lender’s or Issuing Bank’s

commitment to lend or issue or participate in any Letter of Credit hereunder, (B) the participation in or issuance or maintenance of any Letter of Credit or Loan or (C) other similar such commitments, then, promptly after demand by such Lender or Issuing Bank, the Borrowers shall pay to the Administrative Agent for the account of such Lender or Issuing Bank from time to time as specified by such Lender or Issuing Bank additional amounts sufficient to compensate such Lender or Issuing Bank in the light of such circumstances, to the extent that such Lender or Issuing Bank reasonably determines such increase in capital to be allocable to the transactions contemplated hereby. A certificate as to such amounts and giving a reasonable explanation and calculation thereof (to the extent permitted by law) shall be submitted to the Borrowers and the Administrative Agent by such Lender or Issuing Bank and shall be conclusive and binding for all purposes, absent manifest error.

(d) Notices, Etc. Each Lender hereby agrees to use its best efforts to notify the Borrowers of the occurrence of any event referred to in subsection (a), (b) or (c) of this Section 5.04 promptly after becoming aware of the occurrence thereof. Each Borrower shall pay the Administrative Agent, for the account of such Lender, the amount shown as due by such Borrower on any certificate delivered pursuant to this Section 5.04 within ten (10) Business Days after its receipt of the same. The failure of any Lender to provide such notice or to make demand for payment under said subsection shall not constitute a waiver of such Lender’s rights hereunder; provided that, notwithstanding any provision to the contrary contained in this Section 5.04, a Borrower shall not be required to reimburse any Lender for any amounts or costs incurred under subsection (a), (b) or (c) above, more than 270 days prior to the date that such Lender notifies such Borrower in writing thereof, in each case unless, and to the extent that, any such amounts or costs so incurred shall relate to the retroactive application of any event notified to such Borrower which entitles such Lender to such compensation. If any Lender shall subsequently determine that any amount demanded and collected under this Section 5.04 was done so in error, such Lender will promptly return such amount to the applicable Borrower.

(e) Survival of Obligations. Subject to subsection (d) above, the Borrowers’ obligations under this Section 5.04 shall survive the repayment of all other amounts owing to the Lenders, the Administrative Agent and the Issuing Banks under the Loan Documents and the termination of the Commitments.

SECTION 5.05. Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Loans owing to it (other than pursuant to Section 5.04 or 12.07) in excess of its ratable share of payments obtained by all the Lenders on account of the Loans of such Lenders, such Lender shall forthwith purchase from the other Lenders such participation in the Loans owing to them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to (ii) the total amount so recovered from the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. Each Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 5.05 may, to

the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of such Borrower in the amount of such participation. Notwithstanding the foregoing, if any Lender shall obtain any such excess payment involuntarily, such Lender may, in lieu of purchasing participations from the other Lenders in accordance with this Section 5.05, on the date of receipt of such excess payment, return such excess payment to the Administrative Agent for distribution in accordance with Section 5.01(a).

SECTION 5.06. Taxes. (a) All payments by a Borrower hereunder and under the other Loan Documents shall be made in accordance with Section 5.01, free and clear of and without deduction for all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, each Issuing Bank and the Administrative Agent, taxes imposed on its overall net or gross income, receipts, capital, net worth, privilege of transacting business or corporate franchise taxes imposed on it by the jurisdiction under the laws of which such Lender, such Issuing Bank or the Administrative Agent (as the case may be) is organized or any political subdivision thereof and, in the case of each Lender, taxes imposed on its overall net or gross income, receipts, capital, net worth, privilege of transacting business or corporate franchise taxes imposed on it by the jurisdiction of such Lender’s Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable by such Borrower hereunder or under any other Loan Document to any Lender, any Issuing Bank or the Administrative Agent, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.06) such Lender, such Issuing Bank or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Borrower shall make such deductions, and (iii) such Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law.

(b) In addition, each Borrower agrees to pay any present or future stamp or documentary taxes or any other similar taxes or charges that arise from any payment made by such Borrower hereunder or under any other Loan Document to which it is a party or from the execution, delivery or registration of, or otherwise with respect to, this Agreement or any other Loan Document (hereinafter referred to as “Other Taxes”).

(c) The Borrowers will indemnify each Lender, each Issuing Bank and the Administrative Agent for the full amount of Taxes and Other Taxes (including any Taxes and any Other Taxes imposed by any jurisdiction on amounts payable under this Section 5.06) paid by such Lender, such Issuing Bank or the Administrative Agent (as the case may be) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be made within 30 days from the date such Lender, such Issuing Bank or the Administrative Agent (as the case may be) makes written demand therefor. Nothing herein shall preclude the right of any Borrower to contest any such Taxes or Other Taxes so paid, and each Lender, each Issuing Bank and the Administrative Agent (as the case may be) will,

following notice from, and at the expense of, such Borrower, reasonably cooperate with such Borrower to preserve such Borrower’s rights to contest such Taxes or Other Taxes.

(d) Within 30 days after the date of any payment of Taxes, the applicable Borrower will furnish to the Administrative Agent, at its address referred to in Section 12.02, the original or a certified copy of a receipt evidencing payment thereof.

(e) Each Bank represents and warrants that either (i) it is organized under the laws of a jurisdiction within the United States or (ii) it has delivered to the Borrowers or the Administrative Agent duly completed copies of such form or forms prescribed by the United States Internal Revenue Service indicating that such Bank is entitled to receive payments without deduction or withholding of any United States federal income taxes, as permitted by the Code or any tax treaty to which the United States is a party. Each other Lender agrees that, on or prior to the date upon which it shall become a party hereto, and upon the reasonable request from time to time of the Borrowers or the Administrative Agent, such Lender will deliver to the Borrowers and the Administrative Agent (to the extent that it is not prohibited by law from doing so) either (A) a statement that it is organized under the laws of a jurisdiction within the United States or (B) duly completed copies of such form or forms as may from time to time be prescribed by the United States Internal Revenue Service, indicating that such Lender is entitled to receive payments without deduction or withholding of any United States federal income taxes, as permitted by the Internal Revenue Code. Each Bank that has delivered, and each other Lender that hereafter delivers, to the Borrowers and the Administrative Agent the form or forms referred to in the two preceding sentences further undertakes to deliver to the Borrowers and the Administrative Agent, to the extent that it is not prohibited by law from doing so, further copies of such form or forms, or successor applicable form or forms, as the case may be, as and when any previous form filed by it hereunder shall expire or shall become incomplete or inaccurate in any respect. Each Lender represents and warrants that each such form supplied by it to the Administrative Agent and the Borrowers pursuant to this subsection (e), and not superseded by another form supplied by it, is or will be, as the case may be, complete and accurate, and such Lender acknowledges and agrees that nothing contained herein shall in any way limit, waive, or otherwise reduce any claim that the Administrative Agent or the Borrowers may have against such Lender in the event that any such form shall not be complete and accurate.

(f) Any Lender claiming any additional amounts payable pursuant to this Section 5.06 shall use its best efforts (consistent with its internal policy and legal and regulatory restrictions) to change the jurisdiction of its 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, be otherwise disadvantageous to such Lender.

(g) Without prejudice to the survival of any other agreement of the Borrowers hereunder, the agreements and obligations of the Borrowers contained in this Section 5.06 shall survive the repayment of all other amounts owing to the Lenders, the Administrative Agent and the Issuing Banks under the Loan Documents and the termination of the Commitments. If and to the extent that the obligations of the Borrowers under this Section 5.06 are unenforceable for any reason, the Borrowers agree to make the maximum contribution to the payment and satisfaction thereof which is permissible under applicable law.

ARTICLE VII

REPRESENTATIONS AND WARRANTIES

SECTION 7.01. Representations and Warranties of the Obligors. To induce the Administrative Agent, the Issuing Banks and the Lenders to enter into this Agreement and to make Extensions of Credit, each Obligor hereby represents and warrants to the Administrative Agent, each Issuing Bank and each Lender that:

(a) Organization; Power and Authority. Such Obligor is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the

aggregate, reasonably be expected to have a Material Adverse Effect. Such Obligor has the corporate power and authority to own or hold under lease the Properties it purports to own or hold under lease, or proposes to own or hold under lease, to transact the business it transacts and proposes to transact, to execute and deliver the Loan Documents to which it is a party and to perform the provisions thereof.

(b) Authorization, Execution and Delivery. Each Loan Document to which such Obligor is a party has been duly authorized by all necessary corporate action on the part of such Obligor, and upon execution and delivery thereof each such Loan Document will constitute a legal, valid and binding obligation of such Obligor enforceable against such Obligor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). Each Loan Document to which such Obligor is a party has been duly executed and delivered by such Obligor.

(c) Disclosure; No Material Adverse Change; Etc. Such Obligor has disclosed to the Administrative Agent and the Lenders all agreements, instruments and corporate or other restrictions to which it or any of its Subsidiaries is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. Neither the Information Memorandum, the Disclosure Documents nor any of the other reports, financial statements, certificates or other information furnished by or on behalf of such Obligor to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or any other Loan Document or delivered hereunder (as modified or supplemented by, and taken together with, other information so furnished) contains any material misstatement of a fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to forward looking statements, such Obligor represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time and notes that there can be no assurance that such expectations, beliefs or projections will be achieved or accomplished and that such projections are subject to an increasing degree of uncertainty as they relate to later periods of time. Except as disclosed in the Information Memorandum, the Disclosure Documents or in one of the documents, certificates or other writings identified therein, since December 31, 2005, there has been no change in the financial condition, operations, business, Properties or prospects of any Obligor or any Subsidiary of any Obligor except changes that individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no fact known to such Obligor that could reasonably be expected to have a Material Adverse Effect that has not been set forth herein or in the Information Memorandum, the Disclosure Documents or the other documents, certificates and other writings delivered to the Administrative Agent and the Lenders prior to the Closing Date by or on behalf of the Obligors specifically for use in connection with the transactions contemplated hereby.

(d) Financial Condition. The most recent financial statements delivered by such Obligor pursuant to Section 8.01(a)(i) or (ii) (including, without limitations, the financial statements of the Obligors for the fiscal year ended December 31, 2005) present fairly, in all material respects, the financial position and results of operations and cash flows of such Obligor

and its Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absence of footnotes in the case of the statements delivered pursuant to Section 8.01(a)(i). Neither such Obligor nor any of its Subsidiaries had, at the date of the most recent balance sheet referred to above, any Guaranty Obligation, contingent liability or liability for taxes, or any long-term lease or unusual forward or long-term commitment, including any interest rate or foreign currency swap or exchange transaction, which, in any case, was material to such Obligor and its Subsidiaries, taken as a whole, and which was not reflected in the foregoing statements or in the notes thereto. During the period from December 31, 2005 to and including the date hereof there has been no Disposition by such Obligor or any of its Subsidiaries of any material part of its business or Property.

(e) Organization and Ownership of Shares of Subsidiaries.

(c) The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (i) the Administrative Agent (in such capacity) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default or an Event of Default has occurred and is continuing, (ii) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.01), and (iii) except as expressly set forth in the Loan Documents, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Obligors or any of their Subsidiaries or Affiliates that is communicated to or obtained by the Lender serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.01) or in the absence of its own gross negligence or willful misconduct. The

Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrowers, to appoint a successor. If no successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Banks, appoint a successor Administrative Agent which shall be a Lender or an Affiliate of a Lender.

After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 12.04 shall continue in effect for the benefit

of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 10.02. Indemnification. The Lenders agree to indemnify the Administrative Agent (to the extent not reimbursed by the Obligors), ratably according to the respective Percentages of the Lenders, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against the Administrative Agent in any way relating to or arising out of this Agreement or any other Loan Document (other than the Fee Letter) or any action taken or omitted by the Administrative Agent under this Agreement or any other Loan Document (other than the Fee Letter), provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the Administrative Agent’s gross negligence or willful misconduct, as determined by the final and nonappealable judgment of a court of competent jurisdiction. Without limitation of the foregoing, each Lender agrees to reimburse the Administrative Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, syndication, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement or any other Loan Document (other than the Fee Letter) to the extent that the Administrative Agent is entitled to reimbursement for such expenses pursuant to Section 12.04 but is not reimbursed for such expenses by the Obligors.

Document or any other document made, delivered or given in connection herewith or therewith, whether on account of principal, interest, fees, indemnities, costs, expenses (including, without limitation, all reasonable fees, charges and disbursements of counsel to the Administrative Agent, any Issuing Bank or any Lender that are required to be paid by the Borrowers pursuant hereto) or otherwise, in each case strictly in accordance with the express terms hereof (such obligations of each Borrower being herein collectively called, in respect of such Borrower, the “Guaranteed Obligations”), and agrees to pay any and all expenses (including, without limitation, reasonable fees and expenses of counsel) incurred by the Administrative Agent, the Issuing Banks or the Lenders in enforcing any rights under this Article XI. Without limiting the generality of the foregoing, the Guarantor’s liability shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by a Borrower to the Administrative Agent, the Issuing Banks or the Lenders under this Agreement and the other Loan Documents but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving any Borrower.

In addition, the Guarantor hereby further agrees, as an independent obligation, that, if a Borrower fails to pay in full when expressed to be due (whether at stated maturity, upon acceleration or optional prepayment or otherwise) any of the Guaranteed Obligations strictly in accordance with the express terms hereof, the Guarantor will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be paid in full when expressed to be due (whether at stated maturity, upon acceleration or optional prepayment or otherwise) in accordance with the terms of such extension or renewal.

SECTION 11.02. Obligations Unconditional. The obligations of the Guarantor under Section 11.01 are irrevocable, absolute and unconditional, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations of a Borrower hereunder or under any other agreement or instrument referred to herein and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 11.02 that the obligations of the Guarantor hereunder shall be irrevocable, absolute and unconditional under any and all circumstances. Without limiting the generality of the foregoing, the occurrence of one or more of the following shall not preclude the exercise by the Lenders, the Issuing Banks or the Administrative Agent of any right, remedy or power hereunder or alter or impair the liability of the Guarantor hereunder, which shall remain irrevocable, absolute and unconditional as described above:

(a) at any time or from time to time, without notice to the Guarantor, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, waived or renewed, or a Borrower shall be released from any of the Guaranteed Obligations, or any of the Guaranteed Obligations shall be subordinated in right of payment to any other liability of a Borrower;

(b) any of the acts mentioned herein or any agreement or instrument referred to herein or otherwise in connection with the Guaranteed Obligations shall be done or omitted;

(c) any of the Guaranteed Obligations shall be accelerated or otherwise become due prior to their stated maturity, or any of the Guaranteed Obligations shall be amended, supplemented, restated or otherwise modified in any respect, or any right hereunder or under any agreement or instrument referred to herein or otherwise in connection with the Guaranteed Obligations shall be waived, or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released, substituted or exchanged in whole or in part or otherwise dealt with;

(d) a Borrower or any other guarantor or obligor in respect of any of the Guaranteed Obligations (i) becomes insolvent or is unable to pay its debts or fails or admits in writing its inability generally to pay its debts as they become due, (ii) makes a general assignment, arrangement or composition with or for the benefit of its creditors, (iii) institutes or has instituted against it a proceeding seeking a judgment of insolvency or bankruptcy or any other relief under any bankruptcy or insolvency law or other similar law affecting creditors’ rights, or a petition is presented for its winding-up or liquidation, (iv) seeks or becomes subject to the appointment of an administrator, provisional liquidator, conservator, receiver, trustee, custodian or other similar official for it or for all or substantially all its assets, (v) has a secured party take possession of all or substantially all its assets or has a distress, execution, attachment, sequestration or other legal process levied, enforced or sued on or against all or substantially all its assets or (vi) causes or is subject to any event with respect to it which, under the applicable laws of any jurisdiction, has an analogous effect to any of the events specified in clauses (i), (ii), (iii), (iv) or (v) above (any proceeding referred to in this paragraph is herein referred to as an “Insolvency Proceeding”);

(e) this Agreement or any agreement or instrument referred to herein shall be rejected (including pursuant to ▇▇▇▇▇▇▇ ▇▇▇ ▇▇ ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇ Bankruptcy Code, as amended) by an administrator, provisional liquidator, conservator, receiver, trustee, custodian or other similar official for a Borrower or for all or substantially all of a Borrower’s assets in any Insolvency Proceeding;

(f) the occurrence of any Default or Event of Default hereunder or the occurrence of any similar event (howsoever described) under any agreement or instrument referred to herein;

(g) except as otherwise provided in Section 8.02(b)(ii), any consolidation or amalgamation of a Borrower with, any merger of a Borrower with or into, or any transfer by a Borrower of all or substantially all of such Borrower’s assets to, another Person, any change in the legal or beneficial ownership of ownership interests issued by a Borrower, or any other change whatsoever in the objects, capital structure, constitution or business of a Borrower;

(h) any delay, failure or inability of a Borrower or any other guarantor or obligor in respect of any of the Guaranteed Obligations to perform, willful or otherwise, any provision hereunder or any agreement or instrument referred to herein or otherwise in connection with the Guaranteed Obligations;

(i) the failure or breach of any representation or warranty (whether written or oral) made by a Borrower or any other Person herein or in any agreement or instrument referred to herein or otherwise in connection with the Guaranteed Obligations; or any event or circumstance constituting fraud in the inducement or any other similar event or circumstance;

(j) any action or failure to act by any Lender, any Issuing Bank or the Administrative Bank that adversely affects the Guarantor’s right of subrogation arising by reason of any performance by the Guarantor of its obligations under this Article XI;

(k) any suit or other action brought by, or any judgment in favor of, any beneficiaries or creditors of, a Borrower or any other Person for any reason whatsoever, including any suit or action in any way disaffirming, repudiating, rejecting or otherwise calling into question any issue, matter or thing in respect of this Agreement, the other Loan Documents or any agreement or instrument referred to herein or therein or otherwise in connection with the Guaranteed Obligations;

(l) the existence of any claim, set-off, defense or other right which the Guarantor may have at any time against the Administrative Agent, any Issuing Bank, any Lender or any other Person, whether in connection with this Guaranty, the Transactions or any unrelated transaction;

(m) any lack or limitation of status or of power, incapacity or disability of a Borrower or any other guarantor or obligor in respect of any of the Guaranteed Obligations; or

(n) any change in the laws, rules or regulations of any jurisdiction, or any present or future action or order of any Governmental Authority, amending, varying or otherwise affecting the validity or enforceability of any of the Guaranteed Obligations or the obligations of any other guarantor or obligor in respect of any of the Guaranteed Obligations.

The Guarantor hereby expressly waives diligence, presentment, demand of payment, protest and all notices whatsoever, and any requirement that the Lenders, the Issuing Banks or the Administrative Agent exhaust any right, power or remedy (including filing any proof of claim relating to the Guaranteed Obligations in any Insolvency Proceeding) or proceed against any Borrower under this Agreement, any other Loan Document or any agreement or instrument referred to herein or therein, or against any other Person under any other guarantee of, or security for, any of the Guaranteed Obligations, it being understood that this Article XI is a guarantee of payment and not just collection.

SECTION 11.03. Subrogation. The Guarantor hereby agrees that until the payment and satisfaction in full of all Guaranteed Obligations it shall not exercise any right or remedy (including the filing of any proof of claim in any Insolvency Proceeding) against a Borrower or any other guarantor or obligor in respect of any of the Guaranteed Obligations or any security therefor arising by reason of any performance by the Guarantor of its obligations under this Article XI, whether by subrogation or otherwise. In the event that, prior to the payment and satisfaction in full of all Guaranteed Obligations, any amount is received by the Guarantor from a Borrower in respect of the performance by the Guarantor of its obligations under this Article XI, whether by subrogation or otherwise, the Guarantor will promptly following receipt thereof pay such amount to the Administrative Agent for application to any Guaranteed Obligations then owing, whether matured or unmatured.

SECTION 11.04. Reinstatement. The obligations of the Guarantor under this Article XI shall be automatically reinstated if and to the fullest extent that for any reason any payment by or

on behalf of a Borrower in respect of the Guaranteed Obligations is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any Insolvency Proceeding or otherwise, all as though such payment had not been made, and the Guarantor agrees that it will indemnify each Lender, each Issuing Bank and the Administrative Agent on demand for all reasonable costs and expenses (including the reasonable fees and disbursements of counsel) incurred by such Lender, such Issuing Bank and the Administrative Agent in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law.

SECTION 11.05. Remedies Unaffected. The Guarantor agrees that, as between the Guarantor and the Lenders, the Issuing Banks and the Administrative Agent, the Guaranteed Obligations may be declared to be forthwith due and payable as provided herein (and shall be deemed to have become automatically due and payable in the circumstances provided in the proviso contained in Section 9.02) for purposes of Section 11.01, notwithstanding any stay (including under the United States Bankruptcy Code, as amended), injunction or other prohibition preventing the same as against a Borrower, and that, in such event, the Guaranteed Obligations (whether or not due and payable by the Borrowers) shall forthwith become due and payable by the Guarantor for purposes of Section 11.01.

SECTION 11.06. Continuing Guarantee; Liability in Respect of Successor.

(a) The guarantee in this Article XI is a continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising.

(b) In the event that a Borrower shall consolidate or amalgamate with, or merge with or into, or transfer all or substantially all its assets to, another Person, except as otherwise provided in Section 8.02(b)(ii), the Guarantor will continue to be obligated hereunder in respect of the Guaranteed Obligations, whether or not the Guaranteed Obligations are assumed by such Person, and each reference herein to such Borrower shall thereafter instead be a reference to such Person.

(c) Notwithstanding any other provision contained in this Article XI to the contrary, this Guaranty shall automatically terminate as to any Borrower upon the occurrence of the Guaranty Termination Date with respect to such Borrower.

SECTION 12.02. Notices, Etc. All notices and other communications provided for hereunder and under the other Loan Documents shall be in writing (including telegraphic, facsimile, telex or cable communication) and mailed, telegraphed, telecopied, telexed, cabled or delivered, (i) if to any Borrower, at its address at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: Chief Financial Officer (Telecopy No. (▇▇▇) ▇▇▇-▇▇▇▇); (ii) if to the Guarantor, at its address at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: Chief Financial Officer (Telecopy No. (▇▇▇) ▇▇▇-▇▇▇▇); (iii) if to any Bank, at its Domestic Lending Office specified opposite its name on Schedule 1.01; (iv) if to any Issuing Bank, at its address specified in the Issuing Bank Agreement to which it is a party; (v) if to any Lender other than a Bank, at its Domestic Lending Office specified in the Lender Assignment pursuant to which it became a Lender; and (vi) if to the Administrative Agent, at its address at ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇▇ ▇▇▇▇▇ (Telecopy No. (▇▇▇) ▇▇▇-▇▇▇▇); or, as to each party, at such other address as shall be designated by such party in a written notice to the other parties.

SECTION 12.03. No Waiver of Remedies. No failure on the part of any Lender, any Issuing Bank or the Administrative Agent to exercise, and no delay in exercising, any right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any such right preclude any other or further exercise thereof or the

exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.

SECTION 12.04. Costs, Expenses and Indemnification. (a) The Borrowers agree to pay, promptly after delivery to the Borrowers of a reasonably detailed statement therefor, all reasonable costs and expenses of the Administrative Agent in connection with the preparation, negotiation, syndication, execution and delivery of the Loan Documents and any proposed modification, amendment, waiver or consent relating to any Loan Document, including the reasonable fees and disbursements of counsel to the Administrative Agent with respect thereto and with respect to the administration of, and advising the Administrative Agent as to its rights and responsibilities under, this Agreement and the other Loan Documents. The Borrowers further agree to pay, promptly after delivery to the Borrowers of a reasonably detailed statement therefor, all costs and expenses of the Administrative Agent and each Lender (including the fees and disbursements of counsel to the Administrative Agent and counsel for each Lender) in connection with the enforcement (whether through negotiations, legal proceedings or otherwise) of this Agreement, the other Loan Documents and the other documents to be delivered hereunder.

(b) Each Borrower shall indemnify the Administrative Agent, each Issuing Bank, each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnified Person”) against, and hold each Indemnified Person harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnified Person (whether or not such Indemnified Person is named as a party to any proceeding or is otherwise subjected to judicial or legal process arising from any such proceeding), incurred by or asserted against any Indemnified Person arising out of, in connection with, or as a result of (i) the execution or delivery of any Loan Document or any other agreement or instrument contemplated hereby or thereby, the performance by the parties to the Loan Documents of their respective obligations thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any Loan, Letter of Credit or other Extension of Credit to such Borrower or the use or proposed use of the proceeds therefrom (including any refusal by any Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of any Hazardous Materials on or from any property owned or operated by such Borrower or any of its Affiliates, or any Environmental Liability related in any way to such Borrower or any of its Affiliates, or (iv) any actual or prospective claim, litigation, investigation or proceeding relating to any of the foregoing, whether based on contract, tort or any other theory; provided that such indemnity shall not, as to any Indemnified Person, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnified Person.

(c) Each Borrower’s obligations under this Section 12.04 shall survive the repayment of all amounts owing to the Lenders, the Issuing Banks and the Administrative Agent under the Loan Documents and the termination of the Commitments. If and to the extent that the obligations of a Borrower under this Section 12.04 are unenforceable for any reason, such Borrower agrees to make the maximum contribution to the payment and satisfaction thereof

which is permissible under applicable law, which contribution shall in any event not exceed the amount that such Borrower would otherwise have been obligated to pay under this Section 12.04.

SECTION 12.05. Right of Set-off. (a) Upon (i) the occurrence and during the continuance of any Event of Default with respect to a Borrower or the Guarantor and (ii) the making of the request or the granting of the consent specified by Section 9.02 to authorize the Administrative Agent to declare the principal amount outstanding hereunder as to a Borrower to be due and payable pursuant to the provisions of Section 9.02, each Lender and Issuing Bank is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by such Lender or Issuing Bank to or for the credit or the account of the applicable Borrower(s) or, prior to the occurrence of the Guaranty Termination Date with respect to such Borrower(s), the Guarantor, against any and all of the obligations of such Borrower(s) or the Guarantor, respectively, to such Lender or Issuing Bank (as the case may be) existing under any Loan Document and any Promissory Notes of such Borrower held by such Lender or the applicable Issuing Bank Agreement to which such Issuing Bank is a party, as the case may be, irrespective of whether or not such Lender or Issuing Bank shall have made any demand under such Loan Document, such Promissory Notes or such Issuing Bank Agreement, as the case may be, and although such obligations may be unmatured. Each Lender and Issuing Bank agrees to notify promptly the applicable Borrower(s) or the Guarantor (as applicable) after any such set-off and application made by such Lender or Issuing Bank, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of each Lender and Issuing Bank under this Section 12.05 are in addition to other rights and remedies (including other rights of set-off) which such Lender and Issuing Bank may have.

(b) Each Borrower agrees that it shall have no right of off-set, deduction or counterclaim in respect of its obligations hereunder, and that the obligations of the Lenders hereunder are several and not joint. Nothing contained herein shall constitute a relinquishment or waiver of such Borrower’s rights to any independent claim that such Borrower may have against the Administrative Agent or any Lender for the Administrative Agent’s or such Lender’s, as the case may be, gross negligence or willful misconduct, but no Lender shall be liable for any such conduct on the part of the Administrative Agent or any other Lender, and the Administrative Agent shall be liable for any such conduct on the part of any Lender.

SECTION 12.06. Binding Effect. This Agreement shall become effective when it shall have been executed by the Obligors and the Administrative Agent and when the Administrative Agent shall have been notified by each Bank that such Bank has executed it and thereafter shall be binding upon and inure to the benefit of the Obligors, the Administrative Agent and each Lender and their respective successors and assigns, except that no Obligor shall have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lenders.

SECTION 12.07. Assignments and Participation. (a) Each Lender may, with the consent of the Borrowers, the Administrative Agent and the Issuing Banks (such consent not to be unreasonably withheld or delayed and, in the case of the Borrowers, shall not be required if an Event of Default has occurred and is continuing), assign to one or more banks or other financial institutions all or a portion of its rights and obligations under this Agreement and the other Loan

Documents (including all or a portion of its Commitment, the Loans owing to it and any Promissory Notes held by it); provided, however, that (i) each such assignment shall be of a constant, and not a varying, percentage of all of the assigning Lender’s rights and obligations under this Agreement, (ii) the amount of the Commitment of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Lender Assignment with respect to such assignment) shall in no event be less than the lesser of the aggregate amount of such Lender’s Commitment and $5,000,000, (iii) each such assignment shall be to an Eligible Assignee, and (iv) the parties to each such assignment shall execute and deliver to the Administrative Agent, for its acceptance and recording in the Register, a Lender Assignment, together with any Promissory Notes subject to such assignment and a processing and recordation fee (payable by the assigning Lender or such assignee) of $3,500; and provided further, however, that the consent of the Borrowers and the Administrative Agent shall not be required for any assignments by a Lender to any of its Affiliates or to any other Lender or any of its Affiliates. Upon such execution, delivery, acceptance and recording, from and after the effective date specified in each Lender Assignment, which effective date shall be at least five Business Days after the execution thereof (or such earlier date acceptable to the Administrative Agent), (A) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Lender Assignment, have the rights and obligations of a Lender hereunder and (B) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it to an Eligible Assignee pursuant to such Lender Assignment, relinquish its rights and be released from its obligations under this Agreement (and, in the case of a Lender Assignment covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto); provided, however, that the limitation set forth in clause (iii) above shall not apply if an Event of Default shall have occurred and be continuing and the Administrative Agent shall have declared any Loans to be, or any Loans shall have automatically become, immediately due and payable hereunder. Notwithstanding anything to the contrary contained in this Agreement, any Lender may at any time assign all or any portion of the Loans owing to it to any Affiliate of such Lender. No such assignment, other than to an Eligible Assignee in accordance with this Section 12.07, shall release the assigning Lender from its obligations hereunder.

(b) By executing and delivering a Lender Assignment, the Lender assignor thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Lender Assignment, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with any Loan Document or the execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any other instrument or document furnished pursuant thereto; (ii) such assigning Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Obligor or the performance or observance by any Obligor of any of its obligations under any Loan Document or any other instrument or document furnished pursuant thereto; (iii) such assignee confirms that it has received a copy of each Loan Document, together with copies of the financial statements referred to in Section 7.01(d) of this Agreement and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Lender Assignment; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such assigning Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to

make its own credit decisions in taking or not taking action under the Loan Documents; (v) such assignee confirms that it is an Eligible Assignee (unless an Event of Default shall have occurred and be continuing and the Administrative Agent shall have declared any Loans to be immediately due and payable hereunder, in which case no such confirmation is necessary); (vi) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under the Loan Documents as are delegated to the Administrative Agent by the terms thereof, together with such powers as are reasonably incidental thereto; and (vii) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of the Loan Documents are required to be performed by it as a Lender.

(c) The Administrative Agent shall maintain at its address referred to in Section 12.02 a copy of each Lender Assignment delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Obligors, the Administrative Agent, the Issuing Banks and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrowers, any Issuing Bank or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(d) Upon its receipt of a Lender Assignment executed by an assigning Lender and an assignee representing that it is an Eligible Assignee (unless an Event of Default shall have occurred and be continuing and the Administrative Agent shall have declared any Loans to be immediately due and payable hereunder, in which case no such representation is necessary), together with any Promissory Notes subject to such assignment, the processing and recordation fee referred to in subsection (a) above and any written consent to such assignment required by subsection (a) above, the Administrative Agent shall, if such Lender Assignment has been completed and is in substantially the form of Exhibit E, (i) accept such Lender Assignment, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the Borrowers. New and/or replacement Promissory Notes payable to the assignee and the assigning Lender (if the assigning Lender assigned less than all of its rights and obligations hereunder) shall be issued upon request pursuant to Section 3.01(d), and shall be dated the effective date of such Lender Assignment.

(e) Each Lender may sell participations to one or more banks or other financial institutions (a “Participant”) in or to all or a portion of its rights and obligations under the Loan Documents (including all or a portion of its Commitment, the Loans owing to it and any Promissory Notes held by it); provided, however, that (i) such Lender’s obligations under this Agreement (including its Commitment to the Borrowers hereunder) shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) such Lender shall remain the holder of any such Promissory Notes for all purposes of this Agreement, and (iv) the Obligors, the Administrative Agent, the Issuing Banks and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and the other Loan Documents and to approve any

amendment, modification or waiver of any provision of this Agreement or any other Loan Document; provided, that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 12.01 that affects such Participant. Subject to subsection (f) below, the Obligors agree that each Participant shall be entitled to the benefits of Sections 5.04 and 5.06 (and subject to the related obligations under such Sections) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to subsection (a) above. To the extent permitted by law, each Participant shall also be entitled to the benefits of Section 12.05(a) as though it were a Lender, provided such Participant agrees to be subject to Section 5.05 as though it were a Lender.

(f) A Participant shall not be entitled to receive any greater payment under Section 5.04 or 5.06 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.06 unless the Borrowers are notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrowers, to comply with Section 5.06 as though it were a Lender.

(g) Any Lender may, in connection with any assignment or participation or proposed assignment or participation pursuant to this Section 12.07, disclose to the assignee or Participant or proposed assignee or Participant, any information relating to the Obligors furnished to such Lender by or on behalf of any Obligor; provided that prior to any such disclosure, the assignee or Participant or proposed assignee or Participant shall agree, in accordance with the terms of Section 12.08, to preserve the confidentiality of any Confidential Information received by it from such Lender.

(h) If any Lender (or any Participant to which such Lender has sold a participation) shall make any demand for payment under Section 5.04(a) or (c), then within 30 days after any such demand (if, but only if, such demanded payment has been made by the Borrowers), the Borrowers may, with the approval of the Administrative Agent (which approval shall not be unreasonably withheld) and provided that no Default or Event of Default shall then have occurred and be continuing, demand that such Lender assign, at the sole cost and expense of the Borrowers, in accordance with this Section 12.07 to one or more Eligible Assignees designated by the Borrowers, all (but not less than all) of such Lender’s Commitment and the Loans owing to it within the period ending on the later to occur of (x) the last day of the 30-day period described above and (y) the last day of the longest of the then current Interest Periods for such Loans. If any such Eligible Assignee designated by the Borrowers shall fail to consummate such assignment on terms acceptable to such Lender, or if the Borrowers shall fail to designate any such Eligible Assignees for all or part of such Lender’s Commitment or Loans, then such demand by the Borrowers shall become ineffective; it being understood for purposes of this subsection (h) that such assignment shall be conclusively deemed to be on terms acceptable to such Lender, and such Lender shall be compelled to consummate such assignment to an Eligible Assignee designated by the Borrowers, if such Eligible Assignee (1) shall agree to such assignment by entering into a Lender Assignment with such Lender and (2) shall offer compensation to such Lender in an amount equal to all amounts then owing by the Borrowers to such Lender hereunder and under any Promissory Notes made by the Borrowers to such Lender, whether for principal, interest, fees, costs or expenses (other than the demanded payment referred

to above, and payable by the Borrowers as a condition to the Borrowers’ right to demand such assignment) or otherwise (including, without limitation, to the extent not paid by the Borrowers, any payments required pursuant to Section 5.04(b)). Notwithstanding anything set forth above in this subsection (h) to the contrary, the Borrowers shall not be entitled to compel the assignment by any Lender demanding payment under Section 5.04(a) of its Commitment and Loans if, prior to or promptly following any such demand by the Borrowers, such Lender shall have changed or shall change, as the case may be, its Applicable Lending Office for its Eurodollar Rate Loans so as to eliminate the further incurrence of such increased cost. In furtherance of the foregoing, any such Lender demanding payment or giving notice as provided above agrees to use reasonable efforts to so change its Applicable Lending Office if, to do so, would not result in the incurrence by such Lender of additional costs or expenses which it deems material or, in the sole judgment of such Lender, be inadvisable for regulatory, competitive or internal management reasons.

(i) Anything in this Section 12.07 to the contrary notwithstanding, any Lender may assign and pledge all or any portion of its Commitment and the Loans owing to it to any Federal Reserve Bank (and its transferees) as collateral security pursuant to Regulation A of the Board and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.

(j) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrowers, the option to fund all or any part of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Loan, and (ii) nothing herein shall excuse any Granting Lender from its obligations hereunder. The funding of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each Lender hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this subsection (j), any SPC may, with prior notice to, but without the prior written consent of, the Borrowers and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by the Borrowers and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans. This subsection (j) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loans are being funded by an SPC at the time of such amendment. Notwithstanding the foregoing provisions of this subsection, (1) an SPC shall not be deemed to be a Lender or a Participant and shall have no rights under this Agreement except as provided in this subsection (j), and in particular, but not by way of limitation, shall have no rights to compensation for

increased costs pursuant to Article III or Section 5.04 or 5.06, (2) the Granting Lender’s obligations under this Agreement (including its Commitment to the Borrowers hereunder) shall remain unchanged, (3) the Granting Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (4) the Granting Lender shall remain the holder of any Promissory Notes for all purposes of this Agreement, (5) the Obligors, the Administrative Agent, the Issuing Banks and the other Lenders shall continue to deal solely and directly with the Granting Lender in connection with such Granting Lender’s rights and obligations under this Agreement, and (6) the Granting Lender shall indemnify and hold the Borrowers harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be incurred or shall arise as a result of any grant to an SPC contemplated hereunder.

SECTION 12.08. Confidentiality. In connection with the negotiation and administration of this Agreement and the other Loan Documents, each Obligor has furnished and will from time to time furnish to the Administrative Agent, the Issuing Banks and the Lenders (each, a “Recipient”) written information which is identified to the Recipient when delivered as confidential (such information, other than any such information which (a) was publicly available, or otherwise known to the Recipient, at the time of disclosure, (b) subsequently becomes publicly available other than through any act or omission by the Recipient or (c) otherwise subsequently becomes known to the Recipient other than through a Person whom the Recipient knows to be acting in violation of his or its obligations to any Obligor, being hereinafter referred to as “Confidential Information”). The Recipient will not knowingly disclose any such Confidential Information to any third party (other than to those persons who have a confidential relationship with the Recipient), and will take all reasonable steps to restrict access to such information in a manner designed to maintain the confidential nature of such information, in each case until such time as the same ceases to be Confidential Information or as any Obligor may otherwise instruct. It is understood, however, that the foregoing will not restrict the Recipient’s ability to freely exchange such Confidential Information with its Affiliates or with prospective participants in or assignees of the Recipient’s position herein, but the Recipient’s ability to so exchange Confidential Information shall be conditioned upon any such Affiliate’s or prospective participant’s or assignee’s (as the case may be) entering into an agreement as to confidentiality similar to this Section 12.08. It is further understood that the foregoing will not prohibit the disclosure of any or all Confidential Information if and to the extent that such disclosure may be required (i) by a regulatory agency or otherwise in connection with an examination of the Recipient’s records by appropriate authorities, (ii) pursuant to court order, subpoena or other legal process, (iii) otherwise as required by law, or (iv) in order to protect such Recipient’s interests or its rights or remedies hereunder or under the other Loan Documents; in the event of any required disclosure under clause (ii), (iii) or (iv), above, the Recipient agrees to use reasonable efforts to inform the Obligors as promptly as practicable to the extent not prohibited by law.

SECTION 12.09. WAIVER OF JURY TRIAL. THE BORROWERS, THE GUARANTOR, THE ADMINISTRATIVE AGENT, THE ISSUING BANKS AND THE LENDERS EACH HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY

OTHER LOAN DOCUMENT, OR ANY OTHER INSTRUMENT OR DOCUMENT DELIVERED HEREUNDER OR THEREUNDER.

SECTION 12.10. Governing Law; Submission to Jurisdiction. This Agreement and the Promissory Notes shall be governed by, and construed in accordance with, the laws of the State of New York. The Borrowers, the Guarantor, the Lenders, the Issuing Banks and the Administrative Agent each (i) irrevocably submits to the non-exclusive jurisdiction of any New York State court or Federal court sitting in New York City in any action arising out of any Loan Document, (ii) agrees that all claims in such action may be decided in such court, (iii) waives, to the fullest extent it may effectively do so, the defense of an inconvenient forum and (iv) consents to the service of process by mail. A final judgment in any such action shall be conclusive and may be enforced in other jurisdictions. Nothing herein shall affect the right of any party to serve legal process in any manner permitted by law or affect its right to bring any action in any other court.

SECTION 12.11. Relation of the Parties; No Beneficiary. No term, provision or requirement, whether express or implied, of any Loan Document, or actions taken or to be taken by any party thereunder, shall be construed to create a partnership, association, or joint venture between such parties or any of them. No term or provision of the Loan Documents shall be construed to confer a benefit upon, or grant a right or privilege to, any Person other than the parties hereto. The Obligors hereby acknowledge that none of the Administrative Agent, the Issuing Banks nor the Lenders has any fiduciary relationship with or fiduciary duty to any Obligor arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between the Administrative Agent, the Issuing Banks and the Lenders, on the one hand, and the Obligors, on the other hand, in connection herewith or therewith is solely, with respect to the Borrowers, that of creditor and debtor and, with respect to the Guarantor, that of beneficiary and guarantor.

SECTION 12.12. 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.

SECTION 12.13. Survival of Agreement. All covenants, agreements, representations and warranties made herein and in the certificates pursuant hereto shall be considered to have been relied upon by the Administrative Agent, the Issuing Banks and the Lenders and shall survive the making by the Lenders of the Extensions of Credit and the execution and delivery to the Lenders of any Promissory Notes evidencing the Extensions of Credit and shall continue in full force and effect so long as any Promissory Note or any amount due hereunder or under any other Loan Document is outstanding and unpaid, any Letter of Credit is outstanding, or any Commitment of any Lender has not been terminated.

SECTION 12.14. Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any other party) hereby notifies the Obligors that, pursuant to the requirements of the USA Patriot Act, Title III of Pub. L. 107-56, signed into law October 26, 2001 (the “Patriot Act”), it is required to obtain, verify and record information that identifies each Obligor, which information includes the name and address of each Obligor and other

information that will allow such Lender or the Administrative Agent, as applicable, to identify each Obligor in accordance with the Patriot Act.
