By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Facility A Revolving Lenders, the Issuing Bank hereby grants to each Facility A Revolving Lender, and each Facility A Revolving Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Facility A Revolving Commitment Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Facility A Revolving Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Facility A Revolving Commitment Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Facility A Revolving Lender acknowledges

27

and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Revolving Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

     (e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., New York City time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, New York City time, on the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.06 or 2.07 that such payment be financed with an ABR Revolving Borrowing or Swingline Loan in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Revolving Borrowing or Swingline Loan. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Facility A Revolving Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Facility A Revolving Commitment Percentage thereof. Promptly following receipt of such notice, each Facility A Revolving Lender shall pay to the Administrative Agent its Facility A Revolving Commitment Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.09 with respect to Loans made by such Lender (and Section 2.09 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Revolving Loans or a Swingline Loan as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

     (f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising

28

     (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Facility A Revolving Lenders with respect to any such LC Disbursement.

     (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date repayment of such LC Disbursement is due in accordance with Section 2.08(e), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is due to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Revolving Loans. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Facility A Revolving Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.11(b).

     (j) Cash Collateralization. If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing

29

greater than 50% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Facility A Revolving Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clause (h) or (i) of Article VII. Such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the Obligations with respect to Letters of Credit under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 50% of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid), together with any interest amount thereon, shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

     (k) Transition of Existing Letters of Credit.

     (i) Upon the First Borrowing Date, all Existing Letters of Credit shall be deemed to have ceased to be outstanding under the Existing Credit Agreements and shall be deemed instead to have been issued under this Agreement on the First Borrowing Date and to be outstanding under this Agreement.

     (ii) The Borrower represents and warrants to the Administrative Agent, the Issuing Bank and the Lenders that Schedule 2.08 to this Agreement sets forth a true and complete listing of all Existing Letters of Credit.

     SECTION 2.09.  Funding of Borrowings. (a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon, New York City time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders; provided that Swingline Loans shall be made as provided in Section 2.07. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower maintained with the Administrative Agent in New York City and designated by the Borrower in the applicable Borrowing Request; provided that ABR Revolving Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank.

     (b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith

30

on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the lesser of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to the relevant Borrowing. If any such amount required to be paid by any Lender is not in fact made available to the Administrative Agent within three Business Days following the date upon which such Lender receives notice from the Administrative Agent, the Administrative Agent shall be entitled to recover from such Lender, on demand, such amount with interest thereon calculated from such due date at the rate set forth in the preceding sentence plus 3%. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

     SECTION 2.10.  Interest Elections. (a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurocurrency Borrowing, shall have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurocurrency Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. This Section shall not apply to Swingline Borrowings, which may not be converted or continued.

     (b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.02 or 2.06, as the case may be, if the Borrower were requesting a Revolving Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

     (c) Each telephonic and written Interest Election Request shall specify the following information (and in the case of Revolving Borrowings, in compliance with Section 2.05):

     (i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

     (ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

     (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurocurrency Borrowing; and

     (iv) if the resulting Borrowing is a Eurocurrency Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurocurrency Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

31

     (d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

     (e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurocurrency Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Required Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Revolving Borrowing may be converted to or continued as a Eurocurrency Borrowing and (ii) unless repaid, each Eurocurrency Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

     SECTION 2.11.  Termination and Reduction of Commitments. (a) Unless previously terminated, the Revolving Commitments shall terminate on the Revolving Commitment Maturity Date.

     (b) The Borrower may at any time terminate, or from time to time reduce, the Revolving Commitments; provided that (i) each reduction of the Revolving Commitments shall be in an amount that is an integral multiple of $100,000 and not less than $1,000,000 and (ii) the Borrower shall not terminate or reduce the Revolving Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.13, the Revolving Credit Exposures would exceed the total Revolving Commitments.

     (c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Revolving Commitments under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any written notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Revolving Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Revolving Commitments shall be permanent. Each reduction of the Revolving Commitments shall be made ratably among the Lenders in accordance with their respective Revolving Commitments.

     SECTION 2.12.  Repayment of Revolving Loans; Evidence of Debt. (a) The Borrower hereby unconditionally promises to pay on the Revolving Commitment Maturity Date to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan. The Borrower hereby unconditionally promises to pay to the Swingline Lender the then unpaid principal amount of each Swingline Loan on the Swingline Loan Maturity Date; provided that on each date that a Revolving Borrowing is made, the Borrower shall repay all Swingline Loans then outstanding.

     (b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

     (c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Class and Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from

32

the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

     (d) The entries made in the accounts maintained pursuant to paragraph (b) or (c) of this Section shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

     SECTION 2.13.  Optional Prepayments. (a) Subject to Section 2.19, the Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with paragraph (b) of this Section.

     (b) The Borrower shall notify the Administrative Agent (and, in the case of prepayment of a Swingline Loan, the Swingline Lender) by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurocurrency Borrowing, not later than 11:00 a.m., New York City time, three Business Days before the date of prepayment, (ii) in the case of prepayment of an ABR Revolving Borrowing, not later than 11:00 a.m., New York City time, one Business Day before the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 12:00 noon, New York City time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination of the Revolving Commitments as contemplated by Section 2.11, then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.11. Promptly following receipt of any such notice relating to a Revolving Borrowing, the Administrative Agent shall advise the Revolving Lenders of the contents thereof. Each partial prepayment of any Revolving Borrowing shall be in an amount that would be permitted in the case of an advance of a Revolving Borrowing of the same Type as provided in Section 2.05. Each prepayment of a Revolving Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.16.

     SECTION 2.14.  Mandatory Prepayments. (a) If any Capital Stock or Indebtedness shall be issued or incurred by any Consolidated Entity, an amount equal to 50% of the Net Cash Proceeds, in the case of an issuance of Capital Stock (other than (i) to another Consolidated Entity, (ii) as permitted under Section 6.03, (iii) pursuant to employee and director compensation plans or (iv) otherwise for Net Cash Proceeds in an aggregate amount up to $10,000,000), and 100% of the Net Cash Proceeds, in the case of an issuance or incurrence of Indebtedness (other than as permitted under Section 6.01), shall be applied on the date of such issuance or incurrence toward the prepayment of the Term Loans as set forth in Section 2.14(e); provided that no prepayment shall be required to be made pursuant to this subsection (a) if the Leverage Ratio on the last the day of the fiscal quarter most recently ended is 2.00 to 1.00 or less.

     (b) If on any date any Consolidated Entity shall receive Net Cash Proceeds from any Asset Sale or Recovery Event then, unless a Reinvestment Notice shall be delivered in respect thereof, such Net Cash Proceeds shall be applied on such date toward the prepayment of the Term Loans as set forth in Section 2.14(e); provided, that, notwithstanding the foregoing, on each Reinvestment Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with respect to the relevant Reinvestment Event shall be applied toward the prepayment of the Term Loans.

     (c) If, for any fiscal year of the Borrower and its Domestic Subsidiaries commencing with the fiscal year ending December 24, 2005 there shall be Excess Domestic Cash Flow, the Borrower shall, on the relevant Excess Domestic Cash Flow Application Date, apply the EDCF Percentage of such

33

Excess Domestic Cash Flow toward the prepayment of the Term Loans as set forth in Section 2.14(e). Each such prepayment shall be made on a date (an “Excess Domestic Cash Flow Application Date”) no later than five days after the earlier of (i) the date on which the financial statements of the Consolidated Entities referred to in Section 5.01(a) for the fiscal year with respect to which such prepayment is made, are required to be delivered to the Lenders and (ii) the date such financial statements are actually delivered.

     (d) If on any date any Consolidated Entity shall receive Net Cash Proceeds in connection with any Receivables Financing Program then such Net Cash Proceeds shall be applied on such date toward the prepayment of the Term Loans as set forth in Section 2.14(e).

     (e) Amounts to be applied in connection with prepayments made pursuant to this Section 2.14 shall be applied to the prepayment of the Term Loans in accordance with Section 2.21(b) and shall be made, first, to ABR Loans and, second, to Eurocurrency Loans, in each case together with accrued interest to the date of such prepayment on the amount prepaid and the principal amount of Term Loans and accrued interest thereon to be paid by the Borrower pursuant to any such prepayment shall not exceed in the aggregate the applicable portion of Net Cash Proceeds or Excess Domestic Cash Flow, as the case may be, with respect to such prepayment.

     SECTION 2.15.  Fees. (a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Rate on the average daily unused amount of the Revolving Commitment of such Lender during the period from and including the Effective Date to but excluding the date on which such Revolving Commitment terminates. Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the date on which the Revolving Commitments terminate, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of this Section 2.15(a), the unused amount of the Revolving Commitment of any Lender shall be deemed to be the excess of (i) the aggregate Revolving Commitment of such Lender over (ii) the aggregate Revolving Credit Exposure of such Lender (exclusive of Swingline Exposure).

     (b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Revolving Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate as interest on Eurocurrency Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Revolving Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate or rates per annum separately agreed upon between the Borrower and the Issuing Bank on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Revolving Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the issuance, administration, amendment, payment, negotiation, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Revolving Commitments terminate and any such fees accruing after the date on which the Revolving Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within 10 days after demand.

34

All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

     (c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

     (d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees, to the Lenders. Fees paid shall not be refundable under any circumstances.

     SECTION 2.16.  Interest. (a) The Loans comprising each ABR Borrowing (including each Swingline Loan) shall bear interest at the Alternate Base Rate.

     (b) The Loans comprising each Eurocurrency Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

     (c) Notwithstanding the foregoing, immediately upon the occurrence of an Event of Default under Article VII(a), (b), (h) or (i), and in all other cases at the option of the Required Lenders which may be exercised following the occurrence of any other Event of Default, the Loans (and, to the extent permitted by law, overdue interest, fees and other amounts) shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of principal of any Loan, 2% plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section and (ii) in the case of overdue interest, fees and other amounts, 2% plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

     (d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and, in the case of Revolving Loans, upon termination of the Commitments; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Revolving Loan prior to the end of the Revolving Commitment Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurocurrency Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

     (e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

     SECTION 2.17.  Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurocurrency Borrowing:

     (a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

35

     (b) the Administrative Agent is advised by the Majority Facility Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Revolving Borrowing to, or continuation of any Revolving Borrowing as, a Eurocurrency Borrowing shall be ineffective and (ii) if any Borrowing Request requests a Eurocurrency Borrowing, such Borrowing shall be made as an ABR Borrowing.

     SECTION 2.18.  Increased Costs. (a) If any Change in Law shall:

     (i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

     (ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Loan (or of maintaining its obligation to make any Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered. Nothing in this Section 2.18(a) shall override the provisions of Section 2.20.

     (b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

     (c) A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

36

     (d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than 270 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 270-day period referred to above shall be extended to include the period of retroactive effect thereof.

     SECTION 2.19.  Break Funding Payments. In the event of (a) the payment of any principal of any Eurocurrency Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurocurrency Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow any Eurocurrency Loan, continue as a Eurocurrency Loan or prepay any Eurocurrency Revolving Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.13(b) and is revoked in accordance therewith) or (d) the assignment of any Eurocurrency Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.22, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. Such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurocurrency market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

     SECTION 2.20.  Taxes. (a) Any and all payments by or on account of any Obligation shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if any Loan Party shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, a Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) such Loan Party shall make such deductions and (iii) such Loan Party shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

     (c) Each Loan Party shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 30 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any Obligation (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 2.20) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such

37

Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided, however, that such Loan Party shall not be obligated to make payment to the Administrative Agent, any Lender or the Issuing Bank pursuant to this Section 2.20 in respect of penalties, interest or other liabilities attributable to any Indemnified Taxes or Other Taxes, if (i) written demand for such payment has not been made by the Administrative Agent, Lender or Issuing Bank within 90 days from the date on which such party knew of the imposition of Indemnified Taxes or Other Taxes by the relevant Governmental Authority or (ii) such penalties, interest or other liabilities are attributable to the gross negligence or willful misconduct of the Administrative Agent, Lender or Issuing Bank, as the case may be. After the Administrative Agent, Lender or the Issuing Bank learns of the imposition of Indemnified Taxes or Other Taxes, such party will act in good faith to promptly notify the applicable Loan Party of its obligations hereunder. A certificate as to the amount of such payment or liability delivered to the applicable Loan Party by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

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

     (e) If the Administrative Agent, any Lender or the Issuing Bank shall become aware that it is entitled to receive a refund from a relevant Governmental Authority in respect of Indemnified Taxes or Other Taxes as to which it has been indemnified by a Loan Party pursuant to this Section 2.20, it shall promptly notify such Loan Party of the availability of such refund and shall, within 90 days after receipt of a request by such Loan Party (whether as a result of notification that it has made to such Loan Party or otherwise), make a claim to such Governmental Authority for such refund at such Loan Party’s expense. If the Administrative Agent, any Lender or the Issuing Bank receives a refund in respect of any Indemnified Taxes or Other Taxes as to which it has been indemnified by a Loan Party pursuant to this Section 2.20, or with respect to which a Loan Party has paid additional amounts pursuant to this Section 2.20, it shall promptly notify such Loan Party of such refund and shall within 90 days from the date of receipt of such refund pay over the amount of such refund (including any interest paid or credited by the relevant Governmental Authority with respect to such refund) to such Loan Party (but only to the extent of indemnity payments made, or additional amounts paid, by such Loan Party under this Section 2.20 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, Lender or the Issuing Bank; provided, however, that such Loan Party, upon the request of such party, agrees to repay the amount paid over to such Loan Party (plus penalties, interest or other charges due to the appropriate Governmental Authority in connection therewith) to such party in the event such party is required to repay such refund to such Governmental Authority. Nothing in this Section 2.20(e) shall require any Lender to make available its tax returns or any other information relating to its taxes that it deems to be confidential.

     (f) If any Loan Party determines in good faith that a reasonable basis exists for contesting the imposition of Taxes with respect to a Lender, the Administrative Agent or the Issuing Bank, the relevant Lender, the Administrative Agent or the Issuing Bank, as the case may be, shall cooperate with such Loan Party in challenging such Taxes at such Loan Party’s expense if requested by such Loan Party.

     (g) The Administrative Agent, any Lender and the Issuing Bank shall use reasonable efforts to comply timely with any certification, identification, information, documentation or other reporting requirements if such compliance is required by law, regulation, administrative practice or an

38

applicable treaty as a precondition to exemption from, or reduction in the rate of, deduction or withholding of any Indemnified Taxes or Other Taxes for which any Loan Party is required to pay any additional amounts payable to or for the account of the Administrative Agent, any Lender and the Issuing Bank pursuant to this Section 2.20; provided that complying with such requirements would not be materially more onerous (in form, in procedure or in the substance of information disclosed) to the Administrative Agent, any Lender and the Issuing Bank than complying with the comparable information or other reporting requirements imposed under U.S. tax law, regulations and administrative practice.

     (h) Each Foreign Lender, before it signs and delivers this Agreement (in the case of each Foreign Lender listed on the signature pages hereof) or becomes a Lender (in the case of each other Foreign Lender), and from time to time thereafter, before the date any such form expires or becomes obsolete or invalid, shall provide the Borrower and the Administrative Agent with Internal Revenue Service form W-8BEN or W-8ECI in duplicate, as appropriate, or any successor form prescribed by the Internal Revenue Service, certifying that such Lender is entitled to benefits under an income tax treaty to which the United States is a party that exempts the Lender from U.S. withholding tax or reduces the rate of withholding tax on payments of interest for the account of such Lender or certifying that the income receivable pursuant to this Agreement is effectively connected with the conduct of such Lender’s trade or business in the United States and exempt from U.S. withholding tax.

     (i) For any period with respect to which a Foreign Lender has failed to provide the Borrower or the Administrative Agent with the appropriate form as required by Section 2.20(g) or (h) (whether or not such Lender is lawfully able to do so, unless such failure is due to a change in treaty, law or regulation occurring subsequent to the date on which such form originally was required to be provided), such Lender shall not be entitled to indemnification under Section 2.20(a) or (b) with respect to Indemnified Taxes; provided that if a Foreign Lender, otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to U.S. withholding taxes because of its failure to deliver a form required hereunder, the applicable Loan Party shall take such steps as such Lender shall reasonably request to assist such Lender to recover such taxes at the Lender’s expense.

     SECTION 2.21.  Payments Generally; Pro Rata Treatment; Sharing of Set-offs. (a) Each Loan Party shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.18, 2.19 or 2.20, or otherwise) prior to 12:00 noon, New York City time, on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at 270 Park Avenue, New York, New York, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Sections 2.18, 2.19, 2.20 and 9.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

     (b) Each payment (including each prepayment) by the Borrower on account of principal of and interest on the Term Loans shall be made pro rata according to the respective outstanding principal amounts of the Term Loans then held by the Term Lenders. The amount of each principal prepayment of the Term Loans shall be applied to reduce the then remaining installments of the Term Loans, pro rata based upon the respective then remaining principal amounts thereof. Amounts prepaid on account of the Term Loans may not be reborrowed.

39

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

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

     (e) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the lesser of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. If any such amount required to be paid by any Lender or the Issuing Bank is not in fact made available to the Administrative Agent within three Business Days following the date upon which such Lender or Issuing Bank receives notice from the Administrative Agent, the Administrative Agent shall be entitled to recover from such Lender or Issuing Bank, on demand, such amount with interest thereon calculated from such due date at the rate set forth in the preceding sentence plus 3%.

     (f) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.03, 2.07(c), 2.08(d) or (e), 2.09(b) or 2.21(d), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such

40

Sections until all such unsatisfied obligations are fully paid. Any amounts so applied shall nevertheless discharge the obligations of the Borrower to such Lender to the extent of such application.

     SECTION 2.22.  Mitigation Obligations; Replacement of Lenders. (a) If any Lender requests compensation under Section 2.18, or if any Loan Party is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.20, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.18 or 2.20, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Each Loan Party hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment; the mere existence of such costs and expenses shall not be deemed to be disadvantageous to such Lender.

     (b) If any Lender requests compensation under Section 2.18, or if any Loan Party is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.20, or if any Lender defaults in its obligation to fund Loans hereunder, then the applicable Loan Party may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee shall be identified to such Lender by the applicable Loan Party and may be another Lender, if a Lender accepts such assignment); provided that (i) such Loan Party shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, the Issuing Bank and the Swingline Lender), (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements and Swingline Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or such Loan Party (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.18 or payments required to be made pursuant to Section 2.20, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling such Loan Party to require such assignment and delegation cease to apply.

     SECTION 2.23.  Additional Revolving Commitments. Subject to the consent of the Administrative Agent, the Issuing Bank and the Swingline Lender, the Borrower may request that the existing Facility A Revolving Lenders increase their respective Facility A Revolving Commitments and/or that additional Lenders be added to this Agreement until such time as the aggregate Facility A Revolving Commitments are equal to $200,000,000. Each existing Facility A Revolving Lender shall have the right (but not the obligation) to increase its Facility A Revolving Commitment based on its Facility A Revolving Commitment Percentage (with a pro rata right of overallotment extended to the existing Revolving Lenders) on the same terms and conditions being offered to any additional Facility A Revolving Lenders. Schedule 2.04 shall be automatically amended to reflect any existing Facility A Revolving Lender’s increased Facility A Revolving Commitment. By its signature of a counterpart hereof (and subsequent to its delivery of a completed Administrative Questionnaire to the Administrative Agent), each additional Facility A Revolving Lender shall be a “Facility A Revolving Lender” for all purposes hereunder and Schedule 2.04 shall be automatically amended to reflect such additional Facility A Revolving Lender’s Facility A Revolving Commitment. Upon increasing its Facility A Revolving Commitment or becoming a “Facility A Revolving Lender” hereunder, each Facility A Revolving Lender shall automatically be responsible for its Facility A Facility A Revolving Commitment Percentage of the

41

Revolving Credit Exposure and shall pay to the Administrative Agent its Facility A Facility A Revolving Commitment Percentage of the Facility A Revolving Loans which shall then be applied to prepay amounts outstanding to the other Facility A Revolving Lenders in accordance with Section 2.12 and subject to compensation of the Lenders pursuant to Section 2.18.

     SECTION 2.24.  Prepayments Required Due to Currency Fluctuation. (a) Not later than 1:00 p.m., New York City time, on the last Business Day of each fiscal quarter of the Consolidated Entities or at such other time as is reasonably determined by the Administrative Agent (the “Calculation Time”), the Administrative Agent shall determine the Dollar Equivalent of the total Revolving Credit Exposures outstanding as of such date.

     (b) If at the Calculation Time, the Dollar Equivalent of the total Revolving Credit Exposures exceeds the total Revolving Commitments then in effect by 5% or more, then within five Business Days of notice to the Borrower thereof, the Borrower shall prepay Swingline Loans or Revolving Loans or cash collateralize the outstanding Letters of Credit in an aggregate principal amount at least equal to such excess. Nothing set forth in this Section 2.24(b) shall be construed to require the Administrative Agent to calculate compliance under this Section 2.24(b) other than at the times set forth in Section 2.19(a).

     (c) If at the Calculation Time, the Dollar Equivalent of the total Facility B Revolving Loans outstanding exceeds the total Facility B Revolving Commitments then in effect by 5% or more, then within five Business Days of notice to the Borrowers thereof, the Borrower shall prepay Facility B Revolving Loans in an aggregate principal amount at least equal to such excess. Nothing set forth in this Section 2.24(c) shall be construed to require the Administrative Agent to calculate compliance under this Section 2.24(c) other than at the times set forth in Section 2.24(a).

ARTICLE III

Representations and Warranties

     The Borrower represents and warrants to the Lenders (as to itself and its subsidiaries, including, as of the First Borrowing Date, Inveresk and its subsidiaries) that:

     SECTION 3.01.  Organization; Powers. Each of the Consolidated Entities is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to own or lease its property and to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required. Schedule 3.01 sets forth the correct and complete list of each Subsidiary, as of the First Borrowing Date, indicating (a) its jurisdiction of organization, (b) its ownership (by holder and percentage interest), (c) its business and primary geographic scope of operation and (d) whether such Subsidiary is a Material Subsidiary.

     SECTION 3.02.  Authorization; Enforceability. The Transactions to be entered into by each Loan Party are within such Loan Party’s corporate partnership, limited liability company or trust powers and have been duly authorized by all necessary corporate and, if required, stockholder, partner, member or beneficiary action. Each Loan Document to which any Loan Party is a party has been duly executed and delivered by such Loan Party and constitutes a legal, valid and binding obligation of such Loan Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws relating to or affecting creditors’ rights generally, general principles of equity,

42

regardless of whether considered in a proceeding in equity or at law and an implied covenant of good faith and fair dealing.

     SECTION 3.03.  Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect or those which the failure to obtain or make could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, (b) will not violate any applicable law or regulation or the charter, by-laws or other organizational documents of any Consolidated Entity or any order or decree of any Governmental Authority binding on or affecting any Consolidated Entity where such violation of such order or decree, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect, (c) will not violate or result in a default under any indenture, agreement or other instrument binding upon any Consolidated Entity or any of its assets, or give rise to a right thereunder to require any payment to be made by any Consolidated Entity, where such violation or result, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect, and (d) will not result in the creation or imposition of any Lien on any asset of any Consolidated Entity, except pursuant to the terms of any Loan Document.

     SECTION 3.04.  Financial Condition; No Material Adverse Change. (a) The Borrower has heretofore furnished to the Lenders the unaudited pro forma consolidated balance sheets of the Consolidated Entities and the related statements of income, stockholders equity and cash flows as of June 30, 2004. Such financial statements present fairly, in all material respects, on a pro forma basis the estimated financial condition of the Consolidated Entities as of such date after giving effect to (i) the consummation of the Acquisition, (ii) the Loans to be made on the First Borrowing Date and (iii) the payment of fees and expenses in connection with the foregoing.

     (b) The Borrower has heretofore furnished to the Lenders (i) the audited consolidated balance sheets of (A) the Consolidated Entities and the related statements of income, stockholders equity and cash flows as of and for the fiscal years ended December 29, 2001 and December 28, 2002 and December 27, 2003 reported on by PriceWaterhouseCoopers LLP, independent public accountants, and (B) Inveresk and its consolidated subsidiaries and the related statements of income, stockholders equity and cash flows as of and for the fiscal years ended December 31, 2001, December 31, 2002 and December 31, 2003 reported on by Deloitte & Touche LLP, independent public accountants and (ii) the unaudited consolidated and consolidating balance sheets of (A) the Consolidated Entities and the related statements of income, stockholders equity and cash flows as of and for each fiscal quarter since December 27, 2003 as to which such financial statements are available and (B) Inveresk and its consolidated subsidiaries and the related statements of income, stockholders equity and cash flows as of and for each fiscal quarter since December 31, 2003 as to which such financial statements are available. Such financial statements in clauses (i)(A) and (ii)(A) above present fairly, in all material respects, the financial condition and results of operations and cash flows of the Consolidated Entities as of such dates and for such periods in accordance with GAAP.

     (c) Since December 27, 2003, there has been no change that could reasonably be expected to have a Material Adverse Effect.

     SECTION 3.05.  Properties. (a) Each of the Consolidated Entities has good title to, or valid leasehold interests in, all its real and personal property material to its business reflected in the financial statements described in Section 3.04, except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes or to the extent that the failure to do so, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

43

     (b) Each of the Consolidated Entities owns, or is licensed to use, all trademarks, tradenames, service marks, service names, copyrights, patents, domain names and other intellectual property material to its business to the extent that the failure to do so, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect, and, to the knowledge of the Consolidated Entities, the use thereof by the Consolidated Entities does not infringe upon the rights of any other Person, and, to the knowledge of Consolidated Entities, no Person has infringed upon the rights of the Consolidated Entities thereto where such infringement, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

     SECTION 3.06.  Litigation and Environmental Matters. (a) There are no actions, suits or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of any Consolidated Entities, threatened against or affecting any Consolidated Entities (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve this Agreement, any other Loan Document or the Transactions.

     (b) Except for the Disclosed Matters and except with respect to any other matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, no Consolidated Entity (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability.

     (c) Since the date of this Agreement, there has been no change in the status of the Disclosed Matters that, individually or in the aggregate, has resulted in, or materially increased the likelihood of, a Material Adverse Effect.

     SECTION 3.07.  Compliance with Laws and Agreements. Each of the Consolidated Entities is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. No Default has occurred and is continuing.

     SECTION 3.08.  Investment and Holding Company Status. No Consolidated Entity is (a) required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended, or (b) a “holding company” as defined in, or subject to regulation under, the Public Utility Holding Company Act of 1935, as amended.

     SECTION 3.09.  Taxes. Each of the Consolidated Entities has timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the applicable Consolidated Entity has set aside on its books adequate reserves in conformity with GAAP or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.10.  ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $30,000,000 the fair market value of the assets of such

44

Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $30,000,000 the fair market value of the assets of all such underfunded Plans.

     SECTION 3.11.  Disclosure. The Borrower has disclosed to the Lenders all agreements, instruments and corporate or other restrictions to which any Consolidated Entity 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 nor any of the other reports, financial statements, certificates or other information furnished by or on behalf of any Consolidated Entity to the Administrative Agent or any Lender in connection with the negotiation of this Agreement and the other Loan Documents or delivered hereunder or thereunder (as modified or supplemented by other information so furnished) contains any material misstatement of 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 projected financial information, the Borrower represents only that such information was prepared in good faith based upon assumptions believed to be reasonable at the time.

     SECTION 3.12.  Security Documents. The Security Documents are effective to create in favor of the Administrative Agent for its benefit and the ratable benefit of the Lenders a legal, valid and enforceable perfected first-priority Lien on the Collateral as security for the Obligations.

     SECTION 3.13.  Federal Reserve Regulations. (i) No Consolidated Entity is engaged principally, or as one of its important activities, in the business of extending credit for the purposes of buying or carrying Margin Stock (as defined under Regulation U).

     (ii) No part of the proceeds of any Loan, and no Letter of Credit, will be used, whether directly or indirectly, and whether immediately, incidentally or ultimately, for any purpose that entails a violation of, or that is inconsistent with, the provisions of the Regulations of the Board, including Regulation U or X.

     SECTION 3.14.  Solvency. Immediately after the consummation of the Transactions (a) the fair value of the assets of each Loan Party at a fair valuation will exceed its debts and liabilities, subordinated, contingent or otherwise; (b) the present fair saleable value of the property of each Loan Party will be greater than the amount that will be required to pay the probable liability of its debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured, considering all financing alternatives and potential asset sales reasonably available to such Loan Party; (c) each Loan Party will be able to pay its debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured, considering all financing alternatives and potential asset sales reasonably available to such Loan Party; and (d) each Loan Party will not have unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted following the Effective Date.

ARTICLE VIII

The Administrative Agent

     Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

     The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with any Consolidated Entity or other Affiliate thereof as if it were not the Administrative Agent hereunder.

     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, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Loan Documents, whether upon, before or after an Event of Default, that the Administrative Agent is required to exercise in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 9.02), and (c) 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 any Consolidated Entity that is communicated to or obtained by the bank 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 9.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of

61

any Default unless and until written notice thereof is given to the Administrative Agent by a Loan Party or a Lender, and the Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with any Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth in any Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of any Loan Document or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article IV or elsewhere in any Loan Document, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

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

     The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such subagent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

     Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders shall have the right, in consultation with the Borrower, 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 Bank, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 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 acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each 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,

62

continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or related agreement or any document furnished hereunder or thereunder.

     Subject to the foregoing provisions of this Article VIII, the Administrative Agent shall, on behalf of the Lenders, (i) execute each Loan Document other than this Agreement on behalf of the Lenders, (ii) hold and apply the Collateral, and the proceeds thereof, at any time received by it in accordance with the provisions of the Loan Documents, (iii) exercise any and all rights, powers and remedies of the Lenders under the Loan Documents, including the giving of any consent or waiver or the entering into of any amendment, subject to the provisions of Section 9.02, (iv) execute, deliver and file financing statements, assignments and other such agreements, and possess instruments on behalf of the Lenders and (v) in the event of acceleration of the obligations of the Borrower hereunder, exercise the rights of the Lenders under the Loan Documents upon and at the direction of the Required Lenders.

     The Syndication Agent and the Co-Documentation Agents shall not have any right, power, obligation, liability, responsibility or duty under any of the Loan Documents other than those applicable to all Lenders. Without limiting the foregoing, neither the Syndication Agent nor any Co-Documentation Agent shall have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgements with respect to the Syndication Agent and each Co-Documentation Agent as it makes with respect to the Administrative Agent or any other Lender in this Article VIII.

ARTICLE IX

     SECTION 9.02.  Waivers; Amendments. (a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of

63

the Administrative Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

     (b) Neither this Agreement nor any other Loan Document (other than any Hedging Agreement) nor any provision hereof or thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or by the Borrower and the Administrative Agent with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby, (iii) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, or extend the expiration date of any Letter of Credit to a date which is after the Revolving Commitment Maturity Date without the written consent of each Lender affected thereby, (iv) release all or substantially all of the Guarantors from their respective Guarantees under a Guarantee Agreement or limit their liability in respect of such Guarantees or such Guarantee Agreement or their obligation to enter into and provide a Guarantee pursuant to a Guarantee Agreement, without the written consent of the Super-Majority Facility Lenders, (v) release of the Lien of the Administrative Agent on all or substantially all of the Collateral, without the written consent of each Lender, (vi) change Section 2.21(b),(c) or (d) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vii) change any of the provisions of this Section or the definition of “Required Lenders” or “Majority Facility Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or make any determination or grant any consent hereunder, without the written consent of each Lender or (viii) consent to the assignment or transfer by any Loan Party of its rights or obligations hereunder or under the other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, the Issuing Bank or the Swingline Lender hereunder without the prior written consent of the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be.

     SECTION 9.03.  Expenses; Indemnity; Damage Waiver. (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of counsel for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents or any amendments, modifications or waivers of the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out-of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with the Loan Documents, including its rights under this Section, or in connection with the Loans made or Letters of Credit issued

64

hereunder, including all such out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect of such Loans or Letters of Credit.

     (b) The Borrower shall indemnify the Administrative Agent, the Issuing Bank and each Lender, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of (i) the execution or delivery of the Loan Documents or any agreement or instrument contemplated hereby or thereby, the performance by the parties to the Loan Documents of their respective obligations hereunder or thereunder or the consummation of the Transactions or any other transactions contemplated hereby or thereby, (ii) any Loan or Letter of Credit or the use of the proceeds therefrom (including any refusal by the Issuing Bank to honor a demand for payment under a Letter of Credit if the documents presented in connection with such demand do not strictly comply with the terms of such Letter of Credit), (iii) any actual or alleged presence or release of Hazardous Materials on or from any property owned or operated by any Consolidated Entity, or any Environmental Liability related in any way to any Consolidated Entity, 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 and regardless of whether any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from (x) the gross negligence or willful misconduct of such Indemnitee or (y) the breach by such Indemnitee of any if its obligations hereunder.

     (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, the Issuing Bank or the Swingline Lender under paragraph (a) or (b) of this Section, each Lender severally agrees to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as the case may be, such Lender’s Facility A Revolving Commitment Percentage (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent, the Issuing Bank or the Swingline Lender in its capacity as such.

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

     (e) All amounts due under this Section 9.03 shall be payable promptly after written demand therefor.

     SECTION 9.04.  Successors and Assigns. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder or under any other Loan Document without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues

65

any Letter of Credit) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

     (b)(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the corresponding Loans at the time owing to it, and to the extent applicable, the LC Exposure at the time held by it) with the prior written consent (such consent not to be unreasonably withheld) of:

     (A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee;

     (B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or an Approved Fund; and

     (C) the Issuing Bank, provided that no consent of the Issuing Bank shall be required for an assignment of all or any portion of a Term Loan.

     (ii) Assignments shall be subject to the following additional conditions:

     (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment, the amount of the Commitment of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 (in the case of the Revolving Facility) and $1,000,000 (in the case of the Term Facility) unless each of the Borrower and the Administrative Agent otherwise consent, (iii) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement,

     (B) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500 to be paid by the assignor, and

     (C) the assignee, if it shall not be a Lender prior to the date of such assignment, shall deliver to the Administrative Agent an Administrative Questionnaire; and provided further that any consent of the Borrower otherwise required under this paragraph shall not be required if an Event of Default has occurred and is continuing and any consent requested by a Lender of the Borrower and the Administrative Agent under this Section 9.04(b) shall be deemed granted by the Borrower or the Administrative Agent, as the case may be, if it does not respond to such request within 20 days after the written request is delivered to the Borrower and the Administrative Agent in accordance with this Agreement. Subject to acceptance and recording thereof pursuant to paragraph (d) of this Section, from and after the effective date specified in each Assignment and Acceptance the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released

66

from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.18, 2.19, 2.20 and 9.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (e) of this Section.

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

     (d) Upon its receipt of a duly completed Assignment and Acceptance executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section 9.04 and any written consent to such assignment required by paragraph (b) of this Section 9.04, the Administrative Agent shall accept such Assignment and Acceptance and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

     (e) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Issuing Bank or the Swingline Lender, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, the Issuing Bank 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 to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. Subject to paragraph (f) of this Section, each Loan Party agrees that each Participant shall be entitled to the benefits of Sections 2.18, 2.19 and 2.20 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 9.04. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.20(c) as though it were a Lender.

     (f) A Participant shall not be entitled to receive any greater payment under Section 2.18, 2.19 or 2.20 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender

67

shall not be entitled to the benefits of Section 2.20 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the applicable Loan Party, to comply with Section 2.20(e) as though it were a Lender.

     (g) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section 9.04 shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

     (h) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) of such Granting Lender, identified as such in writing from time to time by such Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to Section 2.01 or 2.04, provided that (i) nothing herein shall constitute a commitment to make any Loan by any SPC, (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, such Granting Lender shall be obligated to make such Loan pursuant to the terms hereof and (iii) all credit decisions (including without limitation any decisions with respect to amendments and waivers) will continue to be made by such Granting Lender. The making of a Loan by an SPC hereunder shall utilize the Commitment of the applicable Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any payment under this Agreement for which a Lender would otherwise be liable, for so long as, and to the extent, the related Granting Lender makes such payment. In furtherance of the foregoing, each party hereto hereby agrees that, prior to the date that is one year and one day after the payment in full of all outstanding 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 or similar proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section, any SPC may (i) with notice to, but without the prior written consent of, the Borrower or the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Loans to its Granting Lender in connection with liquidity and/or credit facilities to or for the account of such SPC to fund such Loans and (ii) subject to the provisions of Section 9.12, disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of a surety, guarantee or credit or liquidity enhancement to such SPC.

     SECTION 9.05.  Survival. All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Sections 2.18, 2.19, 2.20 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

     SECTION 9.06.  Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. The Loan Documents and the separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. Except as provided in Section 4.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

     SECTION 9.07.  Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

     SECTION 9.08.  Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates 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 obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

     SECTION 9.09.  Governing Law; Jurisdiction; Consent to Service of Process. (a) This Agreement shall be construed in accordance with and governed by the law of the State of New York.

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

     (c) The Borrower hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any court referred to in paragraph (b) of this Section 9.09. Each of the parties hereto hereby irrevocably waives, to the

69

fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

     (d) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

     SECTION 9.10.  WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

     SECTION 9.11.  Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

     SECTION 9.12.  Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies under any Loan Document or any suit, action or proceeding relating to this Agreement or any Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than a Consolidated Entity. For the purposes of this Section, “Information” means all information received from any Consolidated Entity relating to any Consolidated Entity or its business, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by any Consolidated Entity; provided that, in the case of information received from any Consolidated Entity after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 9.12 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

     SECTION 9.13.  Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the

70

maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon to the date of repayment, shall have been received by such Lender.

     SECTION 9.14.  Joint Creditors. Each of the Loan Parties, each of the Lenders and the Administrative Agent agrees that the Administrative Agent shall be a joint creditor (together with the relevant Lender) of each and every obligation of the Loan Parties towards each of the Lenders under or in connection with the Loan Documents and that, accordingly, the Administrative Agent will have its own independent right to demand performance by the Loan Parties of those obligations. However, any discharge of any such obligation to the Administrative Agent or the relevant Lender shall, to the same extent, discharge the corresponding obligation owing to the other.

     SECTION 9.15.  USA PATRIOT Act. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

     SECTION 9.16.  Consent to Waiver. As of the Effective Date, each Lender which is also a party to the Existing CRL Credit Agreement hereby consents to waive compliance with Section 6.09 thereof for the purpose of permitting the Borrower to enter into this Agreement until the earlier to occur of (i) the First Borrowing Date or (ii) such time as the Commitments have been terminated.
