AMOUNT AND TERMS OF LOANS

Section 2.1. Loans. Subject to and upon the terms and conditions herein set forth, each Lender severally agrees to make a loan or loans (each a “Loan” and, collectively, the “Loans”) to the Borrower, which Loans shall be drawn, to the extent such Lender has a Commitment, as hereinafter provided. Loans (i) may be incurred by the Borrower at any time and from the Closing Date until the Facility Termination Date; (ii) except as otherwise provided, may, at the option of the Borrower, be incurred and maintained as, or Converted into, Loans that are Base Rate Loans or Eurodollar Loans, in each case denominated in Dollars, provided that all Loans made as part of the same Borrowing shall, unless otherwise specifically provided herein, consist of Loans of the same Type; (iii) may be repaid or prepaid and re-borrowed in accordance with the provisions hereof; and (iv) shall not exceed for any

Lender at any time outstanding that aggregate principal amount that, when added to the product at such time of (A) such Lender’s Commitment Percentage, times (B) the aggregate Letter of Credit Outstandings, equals the Commitment of such Lender at such time. In addition, no Loans shall be incurred at any time if, after giving effect thereto, the Borrower would be required to prepay Loans in accordance with Section 5.2(b).

Section 2.2. Borrowing, Continuation or Conversion of Loans.

(a) Borrowings, Continuations and Conversions. The Borrower may, in accordance with the provisions set forth in this Section and subject to the other terms and conditions of this Agreement, (i) request Borrowings, (ii) Convert all or a portion of the outstanding principal amount of Loans of one Type into a Borrowing or Borrowings of another Type of Loans that can be made pursuant to the Facility and (iii) Continue a Borrowing of Eurodollar Loans at the end of the applicable Interest Period as a new Borrowing of Eurodollar Loans with a new Interest Period, provided that (A) any Conversion of Eurodollar Loans into Base Rate Loans shall be made on, and only on, the last day of an Interest Period for such Eurodollar Loans, (B) Base Rate Loans may only be Converted into Eurodollar Loans if no Default under Section 10.1(a) or Event of Default is in existence on the date of the Conversion unless the Required Lenders otherwise agree, and (C) Base Rate Loans may not be Converted into Eurodollar Loans during any period when such Conversion is not permitted under Section 2.6.

(b) Notice of Borrowings, Continuation and Conversion. Each Borrowing, Continuation or Conversion of a Loan shall be made upon notice in the form provided for below, which notice shall be provided by the Borrower to the Administrative Agent at its Notice Office not later than (i) in the case of each Borrowing or Continuation of or Conversion into a Eurodollar Loan, 12:00 noon (local time at its Notice Office) at least three Business Days’ prior to the date of such Borrowing, Continuation or Conversion, and (ii) in the case of each Borrowing of or Conversion to a Base Rate Loan, 12:00 noon (local time at its Notice Office) on the proposed date of such Borrowing or Conversion. Each such request shall be made by an Authorized Officer delivering written notice of such request substantially in the form of Exhibit B-1 hereto (each such notice, a “Notice of Borrowing, Continuation or Conversion”) or by telephone (to be confirmed immediately in writing by delivery of an Authorized Officer of a Notice of Borrowing, Continuation or Conversion), and in any event each such request shall be irrevocable and shall specify (A) the aggregate principal amount of the Loans to be made (which shall be in the Minimum Borrowing Amount) pursuant to such Borrowing or, if applicable, the Borrowings to be Continued or Converted, (B) the date of the Borrowing, Continuation or Conversion (which shall be a Business Day), (C) whether the Borrowing will consist of Base Rate Loans or Eurodollar Loans or, in the case of a Continuation or Conversion, the Loans to be Continued or Converted, and (D) if applicable, the initial Interest Period thereto or, in the case of a Continuation, the new Interest Period. Without in any way limiting the obligation of the Borrower to confirm in writing any telephonic notice permitted to be given hereunder, the Administrative Agent may act prior to receipt of written confirmation without liability upon the basis of such telephonic notice believed by the Administrative Agent in good faith to be from an Authorized Officer of the Borrower entitled to give telephonic notices under this Agreement on behalf of the Borrower. In each such case, the Administrative Agent’s record of the terms of such telephonic notice shall be conclusive absent manifest error.

(c) Minimum Borrowing Amount. The aggregate principal amount of each Borrowing by the Borrower shall not be less than the Minimum Borrowing Amount. No partial Conversion of a Borrowing of Eurodollar Loans shall reduce the outstanding principal amount of the Eurodollar Loans made pursuant to such Borrowing to less than the Minimum Borrowing Amount applicable thereto.

(d) Maximum Borrowings. More than one Borrowing may be incurred by the Borrower on any day, provided that (i) if there are two or more Borrowings on a single day by the Borrower that

consist of Eurodollar Loans, each such Borrowing shall have a different initial Interest Period, and (ii) at no time shall there be more than six Borrowings of Eurodollar Loans outstanding hereunder.

(e) Notice to Lenders. The Administrative Agent shall promptly give each Lender written notice (or telephonic notice promptly confirmed in writing) of (i) each proposed Borrowing, (ii) such Lender’s proportionate share thereof and (iii) the other matters covered by the Notice of Borrowing, Continuation or Conversion relating thereto.

Section 2.3. Pro Rata Borrowings; Disbursement of Funds.

(a) Loans to be Made Pro Rata. The obligation of each Lender to make Loans hereunder and the Commitment of each Lender are several and not joint obligations. All Borrowings shall be made by the Lenders pro rata on the basis of their respective Commitments. It is understood that no Lender shall be responsible for any default by any other Lender in its obligation to make Loans hereunder and that each Lender shall be obligated to make the Loans provided to be made by it hereunder, regardless of the failure of any other Lender to fulfill its Commitment.

(b) Funding of Loans. No later than 2:00 P.M. (local time at the Payment Office) on the date specified in each Notice of Borrowing, Continuation or Conversion, each Lender will make available its pro rata share, if any, of each Borrowing requested to be made on such date in the manner provided below. All amounts shall be made available to the Administrative Agent in Dollars and immediately available funds at the Payment Office and the Administrative Agent shall promptly make available to the Borrower by depositing to its account at the Payment Office the aggregate of the amounts so made available in the type of funds received.

(c) Advance Funding. Unless the Administrative Agent shall have been notified by any Lender prior to the date of Borrowing that such Lender does not intend to make available to the Administrative Agent its portion of the Borrowing or Borrowings to be made on such date, the Administrative Agent may assume that such Lender has made such amount available to the Administrative Agent on such date of Borrowing, and the Administrative Agent, in reliance upon such assumption, may (in its sole discretion and without any obligation to do so) make available to the Borrower a corresponding amount. If such corresponding amount is not in fact made available to the Administrative Agent by such Lender and the Administrative Agent has made available same to the Borrower, the Administrative Agent shall be entitled to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Administrative Agent’s demand therefor, the Administrative Agent shall promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative Agent. The Administrative Agent shall also be entitled to recover from such Lender or the Borrower, as the case may be, interest on such corresponding amount in respect of each day from the date such corresponding amount was made available by the Administrative Agent to the Borrower to the date such corresponding amount is recovered by the Administrative Agent, at a rate per annum equal to (x) if paid by such Lender, the overnight Federal Funds Effective Rate or (y) if paid by the Borrower, the then applicable rate of interest, calculated in accordance with Section 2.5, for the respective Loans (but without any requirement to pay any amounts in respect thereof pursuant to Section 2.7).

(d) Rights Not Prejudiced. Nothing herein and no subsequent termination of the Commitments pursuant to Section 4.2 or 4.3 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder and in existence from time to time or to prejudice any rights that the Borrower may have against any Lender as a result of any default by such Lender hereunder.

Section 2.4. Evidence of Obligations.

(a) Loan Accounts of Lenders. The Obligations of the Borrower owing to each Lender hereunder shall be evidenced by, and each Lender shall maintain in accordance with its usual practice, an account or accounts established by such Lender, which account or accounts shall include the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(b) Loan Accounts of Administrative Agent. The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof, and the Interest Period and applicable interest rate if such Loan is a Eurodollar Loan, (ii) the amount of any principal due and payable or to become due and payable from 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.

(c) Effect of Loan Accounts, etc. The entries made in the accounts maintained pursuant to Section 2.4(a) and (b) 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 or prepay the Loans or any such other amounts in accordance with the terms of this Agreement.

(d) Notes. Upon request of any Lender, the Borrower’s obligation to pay the principal of, and interest on, the Loans made to it by each Lender shall be evidenced by a promissory note of the Borrower substantially in the form of Exhibit A with blanks appropriately completed in conformity herewith (each a “Note” and, collectively, the “Notes”), provided that the decision of any Lender to not request a Note shall in no way detract from the Borrower’s obligation to repay the Loans and other amounts owing by the Borrower to such Lender. Any Note issued by the Borrower to a Lender shall: (i) be executed by the Borrower; (ii) be payable to the order of such Lender and be dated as of the Closing Date (or in the case of any Note issued in connection with an Assignment Agreement, the effective date of such Assignment Agreement); (iii) be payable in the principal amount of Loans evidenced thereby; (iv) mature on the Facility Termination Date; (v) bear interest as provided in Section 2.5 in respect of the Base Rate Loans or Eurodollar Loans, as the case may be, evidenced thereby; (vi) be subject to mandatory prepayment as provided in Section 5.2; and (vii) be entitled to the benefits of this Agreement and the other Credit Documents.

Section 2.5. Interest.

(a) Interest on Base Rate Loans. During such periods as a Loan is a Base Rate Loan, it shall bear interest at a fluctuating rate per annum that shall at all times be equal to the Base Rate in effect from time to time plus the Applicable Base Margin in effect from time to time for such Loan.

(b) Interest on Eurodollar Loans. During such periods as a Loan is a Eurodollar Loan, it shall bear interest at a rate per annum that shall at all times during an Interest Period therefor be the relevant Adjusted Eurodollar Rate for such Eurodollar Loan for such Interest Period plus the Applicable Margin in effect from time to time for such Loan.

(c) Default Interest. Notwithstanding the above provisions, if a Default under Section 10.1(a) or Event of Default is in existence, all outstanding amounts of principal and, to the extent permitted by law, all overdue interest, in respect of each Loan shall bear interest, payable on demand, at a rate per annum equal to 2% per annum above the interest rate that is or would be applicable from time to time pursuant to Section 2.5(a). If any amount (other than the principal of and interest on the Loans) payable by the Borrower under the Credit Documents is not paid when due, such amount shall bear interest, payable on demand, at a rate per annum equal to 2% per annum above the interest rate that is or would be applicable from time to time pursuant to Section 2.5(a).

(d) Accrual and Payment of Interest. Interest shall accrue from and including the date of any Borrowing to but excluding the date of any prepayment or repayment thereof and shall be payable:

(i) in respect of each Base Rate Loan, quarterly in arrears on the last Business Day of each March, June, September and December,

(ii) in respect of each Eurodollar Loan, on the last day of each Interest Period applicable thereto and, in the case of an Interest Period in excess of three months, on the dates that are successively three months after the commencement of such Interest Period, and

(iii) on any repayment, prepayment or Conversion (on the amount repaid, prepaid or Converted), at maturity (whether by acceleration or otherwise) and, after such maturity, on demand.

(e) Computations of Interest. All computations of interest on Eurodollar Loans and other amounts (other than Base Rate Loans) hereunder shall be made on the actual number of days elapsed over a year of 360 days, and all computations of interest on Base Rate Loans hereunder shall be made on the actual number of days elapsed over a year of 365 or 366 days, as applicable.

(f) Information as to Interest Rates. The Administrative Agent upon determining the interest rate for any Borrowing or any change in interest rate applicable to any Borrowing as a result of a change in the Applicable Margin, a change in the Base Rate, the implementation of the default rate or otherwise, shall promptly notify the Borrower and the Lenders thereof, provided that (i) any such change shall be immediately effective as and when such change occurs without regard to when the Administrative Agent provides any such notice, and (ii) the failure of the Administrative Agent to give any such notice shall in no way detract from or affect the obligation of the Borrower to pay interest at the changed rate. If the Administrative Agent is unable to determine the Adjusted Eurodollar Rate for any Borrowing of Eurodollar Loans based on the quotation service referred to in clause (i) of the definition of the term Adjusted Eurodollar Rate, it will promptly so notify the Reference Banks and each Reference Bank will furnish the Administrative Agent timely information for the purpose of determining the Adjusted Eurodollar Rate for such Borrowing. If any one or more of the Reference Banks shall not timely furnish such information, the Administrative Agent shall determine the Adjusted Eurodollar Rate for such Borrowing on the basis of timely information furnished by the remaining Reference Banks.

Section 2.6. Increased Costs, Illegality, etc.

(a) In the event that (x) in the case of clause (i) below, the Administrative Agent or (y) in the case of clauses (ii) and (iii) below, any Lender, shall have determined on a reasonable basis (which determination shall, absent manifest error, be final and conclusive and binding upon all parties hereto):

(i) on any date for determining the Adjusted Eurodollar Rate for any Interest Period that, by reason of any changes arising after the Closing Date affecting the London interbank market, adequate and fair means do not exist for ascertaining the applicable interest rate on the basis provided for in the definition of Adjusted Eurodollar Rate; or

(ii) at any time, that such Lender shall incur increased costs or reductions in the amounts received or receivable hereunder in an amount that such Lender deems material with respect to any Eurodollar Loans (other than any increased cost or reduction in the amount received or receivable resulting from the imposition of or a change in the rate of taxes or similar charges) because of (x) any change since the Closing Date in any applicable law, governmental rule, regulation, guideline, order or request (whether or not having the force of law), or in the

interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline, order or request (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding reserves includable in the Eurodollar Rate pursuant to the definition thereof) or (y) other circumstances adversely affecting the London interbank market or the position of such Lender in such market; or

(iii) at any time, that the making or continuance of any Eurodollar Loan has become unlawful by compliance by such Lender in good faith with any change since the Closing Date in any law, governmental rule, regulation, guideline or order, or the interpretation or application thereof, or would conflict with any thereof not having the force of law but with which such Lender customarily complies or has become impracticable as a result of a contingency occurring after the Closing Date that materially adversely affects the London interbank market;

then, and in each such event, such Lender (or the Administrative Agent in the case of clause (i) above) shall (x) on or promptly following such date or time and (y) within 10 Business Days of the date on which such event no longer exists give notice (by telephone confirmed in writing) to the Borrower and to the Administrative Agent of such determination (which notice the Administrative Agent shall promptly transmit to each of the other Lenders). Thereafter (x) in the case of clause (i) above, Eurodollar Loans shall no longer be available until such time as the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice by the Administrative Agent no longer exist, and any Notice of Borrowing, Notice of Conversion or Notice of Continuation given by the Borrower with respect to Eurodollar Loans that have not yet been incurred, Converted or Continued shall be deemed rescinded by the Borrower or, in the case of a Notice of Borrowing, shall, at the option of the Borrower, be deemed converted into a Notice of Borrowing for Base Rate Loans to be made on the date of Borrowing contained in such Notice of Borrowing, (y) in the case of clause (ii) above, the Borrower shall pay to such Lender, upon written demand therefor, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender shall determine) as shall be required to compensate such Lender, for such increased costs or reductions in amounts receivable hereunder (a written notice as to the additional amounts owed to such Lender, showing the basis for the calculation thereof, which basis must be reasonable, submitted to the Borrower by such Lender shall, absent manifest error, be final and conclusive and binding upon all parties hereto) and (z) in the case of clause (iii) above, the Borrower shall take one of the actions specified in Section 2.6(b) as promptly as possible and, in any event, within the time period required by law.

(b) At any time that any Eurodollar Loan is affected by the circumstances described in Section 2.6(a)(ii) or (iii), the Borrower may (and in the case of a Eurodollar Loan affected pursuant to Section 2.6(a)(iii) the Borrower shall) either (i) if the affected Eurodollar Loan is then being made pursuant to a Borrowing, by giving the Administrative Agent telephonic notice (confirmed promptly in writing) thereof on the same date that the Borrower was notified by a Lender pursuant to Section 2.6(a)(ii) or (iii), cancel said Borrowing, convert the related Notice of Borrowing into one requesting a Borrowing of Base Rate Loans or require the affected Lender to make its requested Loan as a Base Rate Loan, or (ii) if the affected Eurodollar Loan is then outstanding, upon at least one Business Day’s notice to the Administrative Agent, require the affected Lender to Convert each such Eurodollar Loan into a Base Rate Loan, provided that if more than one Lender is affected at any time, then all affected Lenders must be treated the same pursuant to this Section 2.6(b).

(c) If any Lender shall have determined that after the Closing Date, the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged by law with the interpretation or administration thereof, or compliance by such Lender or its parent corporation with any request or directive regarding capital adequacy (whether or not having the

force of law) of any such authority, central bank, or comparable agency, in each case made subsequent to the Closing Date, has or would have the effect of reducing by an amount reasonably deemed by such Lender to be material the rate of return on such Lender’s or its parent corporation’s capital or assets as a consequence of such Lender’s commitments or obligations hereunder to a level below that which such Lender or its parent corporation could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration such Lender’s or its parent corporation’s policies with respect to capital adequacy), then from time to time, within 15 days after demand by such Lender (with a copy to the Administrative Agent), the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or its parent corporation for such reduction. Each Lender, upon determining in good faith that any additional amounts will be payable pursuant to this Section 2.6(c), will give prompt written notice thereof to the Borrower, which notice shall set forth, in reasonable detail, the basis of the calculation of such additional amounts, which basis must be reasonable, although the failure to give any such notice shall not release or diminish any of the Borrower’s obligations to pay additional amounts pursuant to this Section 2.6(c) upon the subsequent receipt of such notice.

(d) Notwithstanding anything in this Agreement to the contrary, (i) no Lender shall be entitled to compensation or payment or reimbursement of other amounts under Section 3.5 or 5.4 for any amounts incurred or accruing more than 270 days prior to the giving of notice to the Borrower of additional costs or other amounts of the nature described in such Sections, and (ii) no Lender shall demand compensation for any reduction referred to in Section 2.6(c) or payment or reimbursement of other amounts under Section 3.5 or 5.4 if it shall not at the time be the general policy or practice of such Lender to demand such compensation, payment or reimbursement in similar circumstances under comparable provisions of other credit agreements.

Section 2.7. Breakage Compensation. The Borrower shall compensate each Lender, upon its written request (which request shall set forth the detailed basis for requesting and the method of calculating such compensation), for all reasonable losses, costs, expenses and liabilities (including, without limitation, any loss, cost, expense or liability incurred by reason of the liquidation or reemployment of deposits or other funds required by such Lender to fund its Eurodollar Loans) which such Lender may sustain: (i) if for any reason (other than a default by such Lender or the Administrative Agent) a Borrowing of Eurodollar Loans does not occur on a date specified therefor in a Notice of Borrowing, Notice of Conversion or Notice of Continuation (whether or not withdrawn by the Borrower or deemed withdrawn pursuant to Section 2.6(a)); (ii) if any repayment, prepayment, Conversion or Continuation of any of its Eurodollar Loans occurs on a date that is not the last day of an Interest Period applicable thereto; (iii) if any prepayment of any of its Eurodollar Loans is not made on any date specified in a notice of prepayment given by the Borrower; (iv) as a result of an assignment by a Lender of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto pursuant to a request by the Borrower pursuant to Section 2.8(b); or (v) as a consequence of (x) any other default by the Borrower to repay or prepay its Eurodollar Loans when required by the terms of this Agreement or (y) an election made pursuant to Section 2.6(b). Such loss, cost, expense and liability 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 that would have accrued on the principal amount of such Loan had such event not occurred, at the interest 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 effect a Borrowing, Conversion or Continuation, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest that would accrue on such principal amount for such period at the interest rate that 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 eurodollar 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 request within 10 days after receipt thereof.

Section 2.8. Change of Lending Office; Replacement of Lenders.

(a) Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Sections 2.6(a)(ii) or (iii), 2.6(c), 3.5 or 5.4 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another Applicable Lending Office for any Loans or Commitment affected by such event, provided that such designation is made on such terms that such Lender and its Applicable Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section.

(b) If any Lender requests any compensation, reimbursement or other payment under Sections 2.6(a)(ii) or (iii), 2.6(c) or 3.5 with respect to such Lender, or if the Borrower is required to pay any additional amount to any Lender or governmental authority pursuant to Section 5.4, or if any Lender is a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with the restrictions contained in Section 12.4(c)), all its interests, rights and obligations under this Agreement to an Eligible Assignee that shall assume such obligations; provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not be unreasonably withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its 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 the Borrower (in the case of all other amounts, including any breakage compensation under Section 2.7 hereof), and (iii) in the case of any such assignment resulting from a claim for compensation, reimbursement or other payments required to be made under Section 2.6(a)(ii) or (iii), 2.6(c) or 3.5 with respect to such Lender, or resulting from any required payments to any Lender or governmental authority pursuant to Section 5.4, such assignment will result in a reduction in such compensation, reimbursement or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(c) Nothing in this Section 2.8 shall affect or postpone any of the obligations of the Borrower or the right of any Lender provided in Section 2.6, 3.5 or 5.4.

ARTICLE III.

(a) Subject to and upon the terms and conditions herein set forth, the Borrower may request a Letter of Credit Issuer at any time and from time to time on or after the Closing Date and prior to the date that is 60 Business Days prior to the Facility Termination Date to issue, for the account of the Borrower or any Subsidiary Guarantor (the Borrower or any such Subsidiary Guarantor, a “Letter of Credit Obligor”), and subject to and upon the terms and conditions herein set forth, such Letter of Credit Issuer agrees to issue from time to time, irrevocable standby letters of credit denominated and payable in Dollars in such form as may be approved by such Letter of Credit Issuer and the Administrative Agent (each such letter of credit (a “Letter of Credit” and collectively, the “Letters of Credit”).

(b) Notwithstanding the foregoing, (i) no Letter of Credit shall be issued, and the Stated Amount of any outstanding Letter of Credit shall not be increased, if after giving effect thereto the Letter

of Credit Outstandings would exceed either (x) the Letter of Credit Commitment Amount (y) when added to the aggregate principal amount of all Loans then outstanding, an amount equal to the Total Commitment at such time; (ii) no individual Letter of Credit shall be issued that has an initial Stated Amount less than $100,000 unless such lesser Stated Amount is acceptable to the Letter of Credit Issuer; and (iii) each Letter of Credit shall have an expiry date (including any renewal periods) occurring not later than the earlier of (A) one year from the date of issuance thereof, and (B) 30 Business Days prior to the Facility Termination Date, in each case on terms acceptable to the Administrative Agent and the relevant Letter of Credit Issuer. In addition, no Letter of Credit shall be issued or increased in amount if after giving effect thereto the Borrower would be required to prepay Loans in accordance with Section 5.2(b).

(c) Notwithstanding the foregoing, in the event a Lender Default exists, no Letter of Credit Issuer shall be required to issue any Letter of Credit unless either (i) such Letter of Credit Issuer has entered into arrangements satisfactory to it and the Borrower to eliminate such Letter of Credit Issuer’s risk with respect to the participation in Letters of Credit of the Defaulting Lender or Lenders, including by cash collateralizing such Defaulting Lender’s or Lenders’ Commitment Percentage of the Letter of Credit Outstandings; or (ii) the issuance of such Letter of Credit, taking into account the potential failure of the Defaulting Lender or Lenders to risk participate therein, will not cause the Letter of Credit Issuer to incur aggregate credit exposure hereunder with respect to Loans and Letter of Credit Outstandings in excess of its Commitment, and the Borrower has undertaken, for the benefit of such Letter of Credit Issuer, pursuant to an instrument satisfactory in form and substance to such Letter of Credit Issuer, not to thereafter incur Loans or Letter of Credit Outstandings hereunder that would cause the Letter of Credit Issuer to incur aggregate credit exposure hereunder with respect to Loans and Letter of Credit Outstandings in excess of its Commitment.

(d) Unless otherwise agreed to by a Letter of Credit Issuer and the Borrower, the rules of the “International Standby Practices 1998” published by the Institute of International Banking Law & Practice (or such later version thereof as may be in effect at the time of issuance) shall apply to each Letter of Credit issued hereunder.

Section 3.2. Letter of Credit Requests: Notices of Issuance.

(a) Whenever it desires that a Letter of Credit be issued, the Borrower shall give the Administrative Agent and the Letter of Credit Issuer written or telephonic notice (in the case of telephonic notice, promptly confirmed in writing if so requested by the Administrative Agent) which, if in the form of written notice shall be substantially in the form of Exhibit B-2, or transmit by electronic communication (if arrangements for doing so have been approved by the Letter of Credit Issuer), prior to 12:00 noon (local time at the Notice Office) at least three Business Days (or such shorter period as may be acceptable to the relevant Letter of Credit Issuer) prior to the proposed date of issuance (which shall be a Business Day) (each a “Letter of Credit Request”), which Letter of Credit Request shall include such supporting documents that such Letter of Credit Issuer customarily requires in connection therewith (including, in the case of a Letter of Credit for an account party other than the Borrower, an application for, and if applicable a reimbursement agreement with respect to, such Letter of Credit). Any such documents executed in connection with the issuance of a Letter of Credit, including the Letter of Credit itself, are herein referred to as “Letter of Credit Documents.” In the event of any inconsistency between any of the terms or provisions of any Letter of Credit Document and the terms and provisions of this Agreement respecting Letters of Credit, the terms and provisions of this Agreement shall control. The Administrative Agent shall promptly notify each Lender of each Letter of Credit Request.

(b) Each Letter of Credit Issuer shall, on the date of each issuance of a Letter of Credit by it, give the Administrative Agent, each applicable Lender and the Borrower written notice of the issuance of

such Letter of Credit, accompanied by a copy to the Administrative Agent of the Letter of Credit or Letters of Credit issued by it. Each Letter of Credit Issuer shall provide to the Administrative Agent a quarterly (or monthly if requested by any applicable Lender) summary describing each Letter of Credit issued by such Letter of Credit Issuer and then outstanding and an identification for the relevant period of the daily aggregate Letter of Credit Outstandings represented by Letters of Credit issued by such Letter of Credit Issuer.

Section 3.3. Agreement to Repay Letter of Credit Drawings.

(a) The Borrower hereby agrees to reimburse (or cause any Letter of Credit Obligor for whose account a Letter of Credit was issued to reimburse) each Letter of Credit Issuer, by making payment directly to such Letter of Credit Issuer in immediately available funds at the payment office of such Letter of Credit Issuer, for any payment or disbursement made by such Letter of Credit Issuer under any Letter of Credit (each such amount so paid or disbursed until reimbursed, an “Unpaid Drawing”) immediately after, and in any event on the date on which, such Letter of Credit Issuer notifies the Borrower (or any such other Letter of Credit Obligor for whose account such Letter of Credit was issued) of such payment or disbursement (which notice to the Borrower (or such other Letter of Credit Obligor) shall be delivered reasonably promptly after any such payment or disbursement), such payment to be made in Dollars, with interest on the amount so paid or disbursed by such Letter of Credit Issuer, to the extent not reimbursed prior to 1:00 P.M. (local time at the payment office of the Letter of Credit Issuer) on the date of such payment or disbursement, from and including the date paid or disbursed to but not including the date such Letter of Credit Issuer is reimbursed therefor at a rate per annum that shall be the rate then applicable to Loans that are Base Rate Loans (plus an additional 2% per annum if not reimbursed on the date of such payment or disbursement), any such interest also to be payable on demand. If by 11:00 A.M. on the Business Day immediately following notice to it of its obligation to make reimbursement in respect of an Unpaid Drawing, the Borrower has not made such reimbursement out of its available cash on hand or a contemporaneous Borrowing hereunder, (x) the Borrower will be deemed to have given a Notice of Borrowing for Base Rate Loans in an aggregate principal amount sufficient to reimburse such Unpaid Drawing (and the Administrative Agent shall promptly give notice to the Lenders of such deemed Notice of Borrowing), (y) the Lenders shall, unless they are legally prohibited from doing so, make the Loans contemplated by such deemed Notice of Borrowing (which Loans shall be considered made under Section 2.1 hereof), and (z) the proceeds of such Base Rate Loans shall be disbursed directly to the applicable Letter of Credit Issuer to the extent necessary to effect such reimbursement, with any excess proceeds to be made available to the Borrower in accordance with the applicable provisions of this Agreement.

(b) The Borrower’s obligation under this Section 3.3 to reimburse, or cause another Letter of Credit Obligor to reimburse, each Letter of Credit Issuer with respect to Unpaid Drawings (including, in each case, interest thereon) shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower or any other Letter of Credit Obligor may have or have had against such Letter of Credit Issuer, the Administrative Agent, any other Letter of Credit Issuer or any Lender, including, without limitation, any defense based upon the failure of any drawing under a Letter of Credit to conform to the terms of the Letter of Credit or any non-application or misapplication by the beneficiary of the proceeds of such drawing; provided, however, that the Borrower shall not be obligated to reimburse, or cause another Letter of Credit Obligor to reimburse, a Letter of Credit Issuer for any wrongful payment made by such Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Letter of Credit Issuer.

Section 3.4. Letter of Credit Participations.

(a) Immediately upon the issuance by a Letter of Credit Issuer of any Letter of Credit, such Letter of Credit Issuer shall be deemed to have sold and transferred to each Lender, and each such Lender (each a “Participant”) shall be deemed irrevocably and unconditionally to have purchased and received from such Letter of Credit Issuer, without recourse or warranty, an undivided interest and participation, to the extent of such Lender’s Commitment Percentage, in such Letter of Credit, each substitute letter of credit, each drawing made thereunder, the obligations of the Borrower under this Agreement with respect thereto (although Letter of Credit Fees shall be payable directly to the Administrative Agent for the account of the Lenders as provided in Section 4.1(b) and the Participants shall have no right to receive any portion of any fees of the nature contemplated by Section 4.1(c)), the obligations of any Letter of Credit Obligor under any Letter of Credit Documents pertaining thereto, and any security for, or guaranty pertaining to, any of the foregoing. Upon any change in the Commitments of the Lenders pursuant to Section 12.4(c), it is hereby agreed that, with respect to all outstanding Letters of Credit and Unpaid Drawings, there shall be an automatic adjustment to the participations pursuant to this Section 3.4 to reflect the new Commitment Percentages of the assigning and assignee Lender.

(b) In determining whether to pay under any Letter of Credit, a Letter of Credit Issuer shall not have any obligation relative to the Participants other than to determine that any documents required to be delivered under such Letter of Credit have been delivered and that they appear to comply on their face with the requirements of such Letter of Credit. Any action taken or omitted to be taken by a Letter of Credit Issuer under or in connection with any Letter of Credit if taken or omitted in the absence of gross negligence or willful misconduct, shall not create for such Letter of Credit Issuer any resulting liability.

(c) In the event that a Letter of Credit Issuer makes any payment under any Letter of Credit and the Borrower shall not have reimbursed (or caused any applicable Letter of Credit Obligor to reimburse) such amount in full to such Letter of Credit Issuer pursuant to Section 3.3(a), such Letter of Credit Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Participant of such failure, and each Participant shall promptly and unconditionally pay to the Administrative Agent for the account of such Letter of Credit Issuer, the amount of such Participant’s Commitment Percentage of such payment in Dollars and in same day funds; provided, however, that no Participant shall be obligated to pay to the Administrative Agent its Commitment Percentage of such unreimbursed amount for any wrongful payment made by such Letter of Credit Issuer under a Letter of Credit as a result of acts or omissions constituting willful misconduct or gross negligence on the part of such Letter of Credit Issuer. If the Administrative Agent so notifies any Participant required to fund a payment under a Letter of Credit prior to 11:00 A.M. (local time at its Notice Office) on any Business Day, such Participant shall make available to the Administrative Agent for the account of the relevant Letter of Credit Issuer such Participant’s Commitment Percentage of the amount of such payment on such Business Day in same day funds. If and to the extent such Participant shall not have so made its Commitment Percentage of the amount of such payment available to the Administrative Agent for the account of the relevant Letter of Credit Issuer, such Participant agrees to pay to the Administrative Agent for the account of such Letter of Credit Issuer, forthwith on demand such amount, together with interest thereon, for each day from such date until the date such amount is paid to the Administrative Agent for the account of such Letter of Credit Issuer at the Federal Funds Effective Rate. The failure of any Participant to make available to the Administrative Agent for the account of the relevant Letter of Credit Issuer its Commitment Percentage of any payment under any Letter of Credit shall not relieve any other Participant of its obligation hereunder to make available to the Administrative Agent for the account of such Letter of Credit Issuer its Commitment Percentage of any payment under any Letter of Credit on the date required, as specified above, but no Participant shall be responsible for the failure of any other Participant to make available to the Administrative Agent for the account of such Letter of Credit Issuer such other Participant’s Commitment Percentage of any such payment.

(d) Whenever a Letter of Credit Issuer receives a payment of a reimbursement obligation as to which the Administrative Agent has received for the account of such Letter of Credit Issuer any payments from the Participants pursuant to Section 3.4(c) above, such Letter of Credit Issuer shall pay to the Administrative Agent and the Administrative Agent shall promptly pay to each Participant that has paid its Commitment Percentage thereof, in Dollars and in same day funds, an amount equal to such Participant’s Commitment Percentage of the principal amount thereof and interest thereon accruing after the purchase of the respective participations, as and to the extent so received.

(e) The obligations of the Participants to make payments to the Administrative Agent for the account of each Letter of Credit Issuer with respect to Letters of Credit shall be irrevocable and not subject to counterclaim, set-off or other defense or any other qualification or exception whatsoever and shall be made in accordance with the terms and conditions of this Agreement under all circumstances, including, without limitation, any of the following circumstances:

(i) any lack of validity or enforceability of this Agreement or any of the other Credit Documents;

(ii) the existence of any claim, set-off defense or other right that the Borrower (or any other Letter of Credit Obligor) may have at any time against a beneficiary named in a Letter of Credit, any transferee of any Letter of Credit (or any person for whom any such transferee may be acting), the Administrative Agent, any Letter of Credit Issuer, any Lender, or other person, whether in connection with this Agreement, any Letter of Credit, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between the Borrower (or any other Letter of Credit Obligor) and the beneficiary named in any such Letter of Credit), other than any claim that the Borrower (or any other Letter of Credit Obligor that is the account party with respect to a Letter of Credit) may have against any applicable Letter of Credit Issuer for gross negligence or willful misconduct of such Letter of Credit Issuer in making payment under any applicable Letter of Credit;

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

(iv) the surrender or impairment of any security for the performance or observance of any of the terms of any of the Credit Documents: or

(v) the occurrence of any Default or Event of Default.

(f) To the extent the Letter of Credit Issuer is not reimbursed by the Borrower, the Participants will reimburse the Letter of Credit Issuer, in proportion to their respective Commitment Percentages, for and against any and all liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements of whatsoever kind or nature that may be imposed on, asserted against or incurred by the Letter of Credit Issuer in performing its respective duties in any way related to or arising out of its issuance of Letters of Credit, provided that no Participants shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, claims, actions, judgments, costs, expenses or disbursements resulting from the Letter of Credit Issuer’s acts or omissions constituting gross negligence or willful misconduct.

Section 3.5. Increased Costs. If after the Closing Date, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or

administration thereof, or compliance by any Letter of Credit Issuer or any Lender with any request or directive (whether or not having the force of law) by any such authority, central bank or comparable agency (in each case made subsequent to the Closing Date) shall either (i) impose, modify or make applicable any reserve, deposit, capital adequacy or similar requirement against Letters of Credit issued by such Letter of Credit Issuer or such Lender’s participation therein, or (ii) shall impose on such Letter of Credit Issuer or any Lender any other conditions affecting this Agreement, any Letter of Credit or such Lender’s participation therein; and the result of any of the foregoing is to increase the cost to such Letter of Credit Issuer or such Lender of issuing, maintaining or participating in any Letter of Credit, or to reduce the amount of any sum received or receivable by such Letter of Credit Issuer or such Lender hereunder (other than any increased cost or reduction in the amount received or receivable resulting from the imposition of or a change in the rate of taxes or similar charges), then, upon demand to the Borrower by such Letter of Credit Issuer or such Lender (a copy of which notice shall be sent by such Letter of Credit Issuer or such Lender to the Administrative Agent), the Borrower shall pay to such Letter of Credit Issuer or such Lender such additional amount or amounts as will compensate any such Letter of Credit Issuer or such Lender for such increased cost or reduction. A certificate submitted to the Borrower by any Letter of Credit Issuer or any Lender, as the case may be (a copy of which certificate shall be sent by such Letter of Credit Issuer or such Lender to the Administrative Agent), setting forth, in reasonable detail, the basis for the determination of such additional amount or amounts necessary to compensate any Letter of Credit Issuer or such Lender as aforesaid shall be conclusive and binding on the Borrower absent manifest error, although the failure to deliver any such certificate shall not release or diminish any of the Borrower’s obligations to pay additional amounts pursuant to this Section 3.5. Reference is hereby made to the provisions of Section 2.6(d) for certain limitations upon the rights of a Letter of Credit Issuer or Lender under this Section.

Section 3.6. Guaranty of Letter of Credit Obligations of Other Letter of Credit Obligors.

(a) The Borrower hereby unconditionally guarantees, for the benefit of the Administrative Agent, each Letter of Credit Issuer and the Lenders, the full and punctual payment of the Obligations of each other Letter of Credit Obligor under each Letter of Credit Document to which such other Letter of Credit Obligor is now or hereafter becomes a party. Upon failure by any such other Letter of Credit Obligor to pay punctually any such amount, the Borrower shall forthwith on demand by the Administrative Agent pay the amount not so paid at the place and in the currency and otherwise in the manner specified in this Agreement or any applicable Letter of Credit Document.

(b) As a separate, additional and continuing obligation, the Borrower unconditionally and irrevocably undertakes and agrees, for the benefit of the Administrative Agent and the Lenders, that, should any amounts not be recoverable from the Borrower under Section 3.6(a) for any reason whatsoever (including, without limitation, by reason of any provision of any Credit Document or any other agreement or instrument executed in connection therewith being or becoming void, unenforceable, or otherwise invalid under any applicable law) then, notwithstanding any notice or knowledge thereof by any Lender, the Administrative Agent, any of their respective Affiliates, or any other person, at any time, the Borrower as sole, original and independent obligor, upon demand by the Administrative Agent, will make payment to the Administrative Agent, for the account of the Lenders and the Administrative Agent, of all such obligations not so recoverable by way of full indemnity, in such currency and otherwise in such manner as is provided in the Credit Documents.

(c) The obligations of the Borrower under this Section shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by the occurrence, one or more times, of any of the following:

(i) any extension, renewal, settlement, compromise, waiver or release in respect to any obligation of any other Letter of Credit Obligor under any Letter of Credit Document, by operation of law or otherwise;

(ii) any modification or amendment of or supplement to this Agreement, any Note or any other Credit Document;

(iii) any release, non-perfection or invalidity of any direct or indirect security for any obligation of the Borrower under this Agreement, any Note or any other Credit Document or of any other Letter of Credit Obligor under any Letter of Credit Document;

(iv) any change in the corporate existence, structure or ownership of any other Letter of Credit Obligor or any insolvency, bankruptcy, reorganization or other similar proceeding affecting any other Letter of Credit Obligor or its assets or any resulting release or discharge of any obligation of any other Letter of Credit Obligor contained in any Letter of Credit Document;

(v) the existence of any claim, set-off or other rights that the Borrower may have at any time against any other Letter of Credit Obligor, the Administrative Agent, any Letter of Credit Issuer any Lender or any other person, whether in connection herewith or any unrelated transactions;

(vi) any invalidity or unenforceability relating to or against any other Letter of Credit Obligor for any reason of any Letter of Credit Document, or any provision of applicable law or regulation purporting to prohibit the payment by any other Letter of Credit Obligor of any Obligations in respect of any Letter of Credit; or

(vii) any other act or omission to act or delay of any kind by any other Letter of Credit Obligor, the Administrative Agent, any Lender or any other person or any other circumstance whatsoever that might, but for the provisions of this Section, constitute a legal or equitable discharge of the Borrower’s obligations under this Section.

(d) The Borrower’s obligations under this Section shall remain in full force and effect until the Commitments shall have terminated and all of the Obligations shall have been paid in full. If at any time any payment of any of the Obligations of any other Letter of Credit Obligor in respect of any Letter of Credit Documents is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of such other Letter of Credit Obligor, the Borrower’s obligations under this Section with respect to such payment shall be reinstated at such time as though such payment had been due but not made at such time.

(e) The Borrower irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any person against any other Letter of Credit Obligor or any other person, or against any collateral or guaranty of any other person.

(f) Until the indefeasible payment in full of all of the Obligations and the termination of the Commitments of the Lenders hereunder, the Borrower shall have no rights, by operation of law or otherwise, upon making any payment under this Section to be subrogated to the rights of the payee against any other Letter of Credit Obligor with respect to such payment or otherwise to be reimbursed, indemnified or exonerated by any other Letter of Credit Obligor in respect thereof.

(g) In the event that acceleration of the time for payment of any amount payable by any other Letter of Credit Obligor under any Letter of Credit Document is stayed upon insolvency, bankruptcy or reorganization of such other Letter of Credit Obligor, all such amounts otherwise subject to acceleration under the terms of any applicable Letter of Credit Document shall nonetheless be payable by the Borrower under this Section forthwith on demand by the Administrative Agent.

ARTICLE V.

PAYMENTS

Section 5.1. Voluntary Prepayments. The Borrower shall have the right to prepay any of the Loans, in whole or in part, without premium or penalty (except as specified below), from time to time on the following terms and conditions:

(a) the Borrower shall give the Administrative Agent at the Notice Office written or telephonic notice (in the case of telephonic notice, promptly confirmed in writing if so requested by the Administrative Agent) of its intent to prepay the Loans, the amount of such prepayment and (in the case of Eurodollar Loans) the specific Borrowing(s) pursuant to which made, which notice shall be received by the Administrative Agent by (i) 12:00 noon (local time at the Notice Office) three Business Days prior to the date of such prepayment, in the case of any prepayment of Eurodollar Loans, or (ii) 12:00 noon (local time at the Notice Office) one Business Day prior to the date of such prepayment, in the case of any prepayment of Base Rate Loans, and which notice shall promptly be transmitted by the Administrative Agent to each of the Lenders;

(b) in the case of prepayment of any Borrowings, each partial prepayment of any such Borrowing shall be in an aggregate principal amount of at least the Minimum Borrowing Amount applicable thereto;

(c) no partial prepayment of any Loans made pursuant to a Borrowing shall reduce the aggregate principal amount of such Loans outstanding pursuant to such Borrowing to an amount less than the Minimum Borrowing Amount applicable thereto, provided that the foregoing limitation shall not apply if such Loans are being prepaid in full;

(d) each prepayment in respect of any Loans made pursuant to a Borrowing shall be applied pro rata among such Loans; and

(e) each prepayment of Eurodollar Loans pursuant to this Section 5.1 on any date other than the last day of the Interest Period applicable thereto shall be accompanied by any amounts payable in respect thereof under Section 2.7.

Section 5.2. Mandatory Prepayments. The Loans shall be subject to mandatory repayment or prepayment, and the Letter of Credit Outstandings shall be subject to cash collateralization requirements, in accordance with the following provisions:

(a) Facility Termination Date. The Borrower shall repay the entire principal amount outstanding of any Loans on the Facility Termination Date and, if any Letter of Credit Outstandings exist, then on such date the Borrower shall cause each Letter of Credit to be replaced or cash collateralized in accordance with the provisions of Section 5.2(b).

(b) Mandatory Prepayment—Loans Exceed Total Commitment. If on any date (after giving effect to any other payments on such date) the sum of (i) the aggregate outstanding principal amount of Loans plus (ii) the aggregate amount of Letter of Credit Outstandings, exceeds the Total Commitment as then in effect, then the Borrower shall prepay on such date that principal amount of Loans and, after Loans have been paid in full, Unpaid Drawings, in an aggregate amount at least equal to such excess and conforming in the case of partial prepayments of Loans to the requirements as to the amounts of partial prepayments of Loans that are contained in Section 5.1. If at any time the aggregate amount of Letter of Credit Outstandings exceeds the Total Commitment as then in effect, or if at any time the aggregate

amount of Letter of Credit Outstandings (or any particular Letter of Credit or grouping of Letters of Credit) exceeds the Letter of Credit Commitment Amount, then the Borrower shall pay to the Administrative Agent an amount in cash and/or Cash Equivalents equal to such excess and the Administrative Agent shall hold such payment as security for the reimbursement obligations of the Borrower and any other Credit Parties hereunder in respect of Letters of Credit pursuant to a cash collateral agreement to be entered into in form and substance reasonably satisfactory to the Administrative Agent, each Letter of Credit Issuer and the Borrower (which shall permit certain investments in Cash Equivalents satisfactory to the Administrative Agent, each Letter of Credit Issuer and the Borrower until the proceeds are applied to the secured obligations).

If at the end of any such 12 month period any portion of such Net Cash Proceeds has not been so reinvested or upon the occurrence and continuation of an Event of Default, the Borrower will immediately make a prepayment of the principal of first, Unpaid Drawings, and second, after all Unpaid Drawings have been paid in full, Loans.

Any payments under this Agreement that are made later than 12:00 noon (local time at the Payment Office) shall be deemed to have been made on the next succeeding Business Day. Whenever any payment to be made hereunder shall be stated to be due on a day that is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest shall be payable during such extension at the applicable rate in effect immediately prior to such extension.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, Unpaid Drawings, interest and Fees then due hereunder and an Event of Default is not then in existence, 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 Unpaid Drawings then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and Unpaid Drawings then due to such parties.

Section 5.4. Net Payments.

(a) All payments made by the Borrower hereunder, under any Note or any other Credit Document, shall be made without setoff, counterclaim or other defense. Except as provided for in Section 5.4(b), all such payments will be made free and clear of, and without deduction or withholding for, any

present or future taxes, levies, imposts, duties, fees, assessments or other charges of whatever nature now or hereafter imposed by any jurisdiction or by any political subdivision or taxing authority thereof or therein with respect to such payments (but excluding, except as provided in the second succeeding sentence, any tax, imposed on or measured by the net income or net profits of a Lender pursuant to the laws of the jurisdiction under which such Lender is organized or the jurisdiction in which the principal office or Applicable Lending Office of such Lender is located or any subdivision thereof or therein) and all interest, penalties or similar liabilities with respect to such non-excluded taxes, levies imposts, duties, fees, assessments or other charges (all such non-excluded taxes, levies, imposts, duties, fees assessments or other charges being referred to collectively as “Taxes”). If any Taxes are so levied or imposed, the Borrower agrees to pay the full amount of such Taxes and such additional amounts as may be necessary so that every payment by it of all amounts due hereunder, under any Note or under any other Credit Document, after withholding or deduction for or on account of any Taxes will not be less than the amount provided for herein or in such Note or in such other Credit Document. If any amounts are payable in respect of Taxes pursuant to the preceding sentence, the Borrower agrees to reimburse each Lender, upon the written request of such Lender for taxes imposed on or measured by the net income or profits of such Lender pursuant to the laws of the jurisdiction in which such Lender is organized or in which the principal office or Applicable Lending Office of such Lender is located or under the laws of any political subdivision or taxing authority of any such jurisdiction in which the principal office or Applicable Lending Office of such Lender is located and for any withholding of income or similar taxes imposed by the United States of America as such Lender shall determine are payable by, or withheld from, such Lender in respect of such amounts so paid to or on behalf of such Lender pursuant to the preceding sentence and in respect of any amounts paid to or on behalf of such Lender pursuant to this sentence, which request shall be accompanied by a statement from such Lender setting forth, in reasonable detail, the computations used in determining such amounts. The Borrower will furnish to the Administrative Agent within 45 days after the date the payment of any Taxes, or any withholding or deduction on account thereof, is due pursuant to applicable law certified copies of tax receipts, or other evidence satisfactory to the Lender, evidencing such payment by the Borrower. The Borrower will indemnify and hold harmless the Administrative Agent and each Lender, and reimburse the Administrative Agent or such Lender upon its written request, for the amount of any Taxes so levied or imposed and paid or withheld by such Lender.

(b) Each Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for Federal income tax purposes agrees to provide to the Borrower and the Administrative Agent on or prior to the Closing Date, or in the cases of a Lender that is an assignee or transferee of an interest under this Agreement pursuant to Section 12.4 (unless the respective Lender was already a Lender hereunder immediately prior to such assignment or transfer and such Lender is in compliance with the provisions of this Section 5.4(b)), on the date of such assignment or transfer to such Lender, and from time to time thereafter if required by the Borrower or the Administrative Agent: (i) two accurate and complete original signed copies of Internal Revenue Service Form 1001, 4224, W-8BEN, W-8ECI, W-8EXP or W-8IMY (or successor, substitute or other appropriate forms) certifying to such Lender’s entitlement to a complete exemption from, or a reduced rate of withholding from, United States withholding tax with respect to payments to be made under this Agreement, any Note or any other Credit Document, or (ii) if the Lender cannot deliver the appropriate Internal Revenue Service Forms referred to in clause (i) above, (x) a certificate in form and substance satisfactory to the Administrative Agent (any such certificate, an “Exemption Certificate”) and (y) other appropriate documentation certifying to such Lender’s entitlement to a complete exemption from, or reduced rate of withholding from, United States withholding tax with respect to payments of interest to be made under this Agreement, any Note or any other Credit Document. In addition, each Lender agrees that from time to time after the Closing Date, when a lapse in time or change in circumstances renders the previous certification obsolete or inaccurate in any material respect, it will deliver to the Borrower and the Administrative Agent two new accurate and complete original signed copies of the applicable Internal Revenue Service Form, or an Exemption

Certificate and related documentation, as the case may be, and such other forms as may be required in order to confirm or establish the entitlement of such Lender to a continued exemption from or reduction in United States withholding tax with respect to payments under this Agreement, any Note or any other Credit Document, or it shall immediately notify the Borrower and the Administrative Agent of its inability to deliver any such Form or Exemption Certificate and related documentation, in which case such Lender shall not be required to deliver any such Form or Exemption Certificate and related documentation pursuant to this Section 5.4(b). Notwithstanding anything to the contrary contained in Section 5.4(a), but subject to Section 12.4(c) and the immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or other similar taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for United States federal income tax purposes and that has not provided to the Borrower such Forms or such Exemption Certificate and related documentation that establish a complete exemption from or reduction in the rate of such deduction or withholding and (y) the Borrower shall not be obligated pursuant to Section 5.4(a) hereof to gross-up payments to be made to a Lender in respect of income or similar taxes imposed by the United States or any additional amounts with respect thereto (I) if such Lender has not provided to the Borrower the Internal Revenue Service forms required to be provided to the Borrower pursuant to this Section 5.4(b) or (ii) in the case of a payment other than interest, to a Lender described in clause (ii) above, to the extent that such forms do not establish a complete exemption from withholding of such taxes. Notwithstanding anything to the contrary contained in Section 5.4(a), but subject to Section 12.4(c) and the immediately succeeding sentence, (x) the Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold income or other similar taxes imposed by the United States (or any political subdivision or taxing authority thereof or therein) from interest, fees or other amounts payable hereunder for the account of any Lender that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for United States federal income tax purposes and that has not provided to the Borrower such forms that establish a complete exemption from such deduction or withholding and (y) the Borrower shall not be obligated pursuant to Section 5.4(a) hereof to gross-up payments to be made to a Lender in respect of income or similar taxes imposed by the United States or any additional amounts with respect thereto (i) if such Lender has not provided to the Borrower the Internal Revenue Service forms required to be provided to the Borrower pursuant to this Section 5.4(b) or (ii) in the case of a payment other than interest, to a Lender described in clause (ii) above, to the extent that such forms do not establish a complete exemption from withholding of such taxes. Notwithstanding anything to the contrary contained in the preceding sentence or elsewhere in this Section 5.4 and except as specifically provided for in Section 12.4(c), the Borrower agrees to pay additional amounts and indemnify each Lender in the manner set forth in Section 5.4(a) (without regard to the identity of the jurisdiction requiring the deduction or withholding) in respect of any Taxes deducted or withheld by it as described in the previous sentence as a result of any changes after the Closing Date in any applicable law, treaty, governmental rule, regulation, guideline or order, or in the interpretation thereof, relating to the deducting or withholding of income or similar Taxes.

(c) If any Lender, in its sole opinion, determines that it has finally and irrevocably received or been granted a refund in respect of any Taxes paid as to which indemnification has been paid by the Borrower pursuant to this Section, it shall promptly remit such refund (including any interest received in respect thereof), net of all actual out-of-pocket costs and expenses; provided, that the Borrower agrees to promptly return any such refund (plus interest) to such Lender in the event such Lender is required to repay such refund to the relevant taxing authority. Any such Lender shall provide the Borrower with a copy of any notice of assessment from the relevant taxing authority (redacting any unrelated confidential information contained therein) requiring repayment of such refund. Nothing contained herein shall impose an obligation on any Lender to apply for any such refund.

REPRESENTATIONS AND WARRANTIES

In order to induce the Lenders to enter into this Agreement and to make the Loans and to issue and to participate in the Letters of Credit provided for herein, the Borrower makes the following representations and warranties to, and agreements with, the Lenders, all of which shall survive the execution and delivery of this Agreement and each Credit Event:

Section 7.1. Corporate Status, etc. Each of the Borrower and its Subsidiaries (i) is a duly organized or formed and validly existing corporation, partnership or limited liability company, as the case may be, in good standing or full force and effect, as applicable, under the laws of the jurisdiction of its formation and has the corporate, partnership or limited liability company power and authority, as applicable, to own its property and assets and to transact the business in which it is engaged and presently proposes to engage, and (ii) has duly qualified and is authorized to do business in all jurisdictions where it is required to be so qualified except where the failure to be so qualified would not have a Material Adverse Effect. Schedule 7.1 hereto lists, as of the Closing Date, each Subsidiary of the Borrower (and the direct and indirect ownership interest of the Borrower therein).

Section 7.2. Corporate Power and Authority, etc. Each Credit Party has the corporate or other organizational power and authority to execute, deliver and carry out the terms and provisions of the Credit Documents to which it is party and has taken all necessary corporate or other organizational action to authorize the execution, delivery and performance of the Credit Documents to which it is party. Each Credit Party has duly executed and delivered each Credit Document to which it is party, and each Credit Document to which it is party constitutes the legal, valid and binding agreement or obligation of such

Credit Party enforceable in accordance with its terms, except to the extent that the enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws generally affecting creditors’ rights and by equitable principles (regardless of whether enforcement is sought in equity or at law).

Section 7.3. No Violation. Neither the execution, delivery and performance by any Credit Party of the Credit to which it is party nor compliance with the terms and provisions thereof (i) will contravene any material provision of any law, statute, rule, regulation, order, writ, injunction or decree of any Governmental Authority applicable to such Credit Party or its material properties and assets, (ii) will conflict with or result in any breach of, any of the terms, covenants, conditions or provisions of, or constitute a default under, or result in the creation or imposition of (or the obligation to create or impose) any Lien (other than the Liens created pursuant to the Security Documents) upon any of the property or assets of such Credit Party pursuant to the terms of any promissory note, bond, debenture, indenture, mortgage, deed of trust, credit or loan agreement, or any other material agreement or other instrument, to which such Credit Party is a party or by which it or any of its property or assets are bound or to which it may be subject, or (iii) will violate any provision of the certificate or articles of incorporation, code of regulations or by-laws, or other charter documents of such Credit Party.

Section 7.4. Governmental Approvals. No order, consent, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, any Governmental Authority is required to authorize or is required as a condition to (i) the execution, delivery and performance by any Credit Party of any Credit Document to which it is a party, or (ii) the legality, validity, binding effect or enforceability of any Credit Document to which any Credit Party is a party, except the filing and recording of financing statements and other documents necessary in order to perfect the Liens created by the Security Documents.

Section 7.5. Litigation. There are no actions, suits or proceedings pending or, to, the knowledge of the Borrower, threatened with respect to the Borrower or any of its Subsidiaries (i) that have, or could reasonably be expected to have, a Material Adverse Effect, or (ii) that question the validity or enforceability of any of the Credit Documents, or of any action to be taken by the Borrower or any of the other Credit Parties pursuant to any of the Credit Documents.

Section 7.6. Use of Proceeds; Margin Regulations.

(a) The proceeds of all Loans shall be utilized to refinance existing senior debt facilities, provide funds for Permitted Acquisitions and provide working capital and funds for general corporate and other lawful purposes not inconsistent with the requirements of this Agreement.

(b) No part of the proceeds of any Credit Event will be used directly or indirectly to purchase or carry Margin Stock, or to extend credit to others for the purpose of purchasing or carrying any Margin Stock, in violation of any of the provisions of Regulation U or X of the Board of Governors of the Federal Reserve System. The Borrower is not engaged in the business of extending credit for the purpose of purchasing or carrying any Margin Stock. At no time would more than 25% of the value of the assets of the Borrower or of the Borrower and its consolidated Subsidiaries that are subject to any “arrangement” (as such term is used in Section 221.2(g) of such Regulation U) hereunder be represented by Margin Stock.

Section 7.7. Financial Statements, etc.

(a) The Borrower has furnished to the Lenders and the Administrative Agent complete and correct copies of (i) the audited consolidated balance sheets of the Borrower and its consolidated

subsidiaries as of December 31, 2002 and the related audited consolidated statements of income, shareholders’ equity, and cash flows of the Borrower and its consolidated subsidiaries for the fiscal years then ended, accompanied by the report thereon of KPMG LLP; and (ii) the condensed consolidated balance sheets of the Borrower and its consolidated subsidiaries as of June 30, 2003 and the related condensed consolidated statements of income and of cash flows of the Borrower and its consolidated subsidiaries for the fiscal period then ended, as included in the Borrower’s Report on Form 10-Q for the fiscal quarter ended June 30, 2003, filed with the SEC. All such financial statements have been prepared in accordance with GAAP, consistently applied (except as stated therein), and fairly present the financial position of the entities described in such financial statements as of the respective dates indicated and the consolidated results of their operations and cash flows for the respective periods indicated, subject in the case of any such financial statements that are unaudited, to normal audit adjustments, none of which will involve a Material Adverse Effect. The Borrower and its Subsidiaries did not have, as of the date of the latest financial statements referred to above, and will not have as of the Closing Date after giving effect to the incurrence of Loans hereunder, any material or significant contingent liability or liability for taxes, long-term lease or unusual forward or long-term commitment that is not reflected in the foregoing financial statements or the notes thereto in accordance with GAAP and that in any such case is material in relation to the business, operations, properties, assets, financial or other condition or prospects of the Borrower or any of its Subsidiaries.

(b) The Borrower has delivered or caused to be delivered to the Lenders prior to the execution and delivery of this Agreement financial projections prepared by management of the Borrower for the Borrower and its Subsidiaries for the fiscal years 2003 through 2006 (the “Financial Projections”). The Financial Projections were prepared on behalf of the Borrower in good faith after taking into account historical levels of business activity of the Borrower and its Subsidiaries, known trends, including general economic trends, and all other information, assumptions and estimates considered by management of the Borrower and its Subsidiaries to be pertinent thereto; provided, that (i) no representation or warranty is made as to the impact of future general economic conditions or as to whether the Borrower’s projected consolidated results as set forth in the Financial Projections will actually be realized, and (ii) the Administrative Agent and the Lenders understand that the Financial Projections are subject to uncertainties and other factors that could cause actual results to differ materially from those projected, anticipated or implied.

Section 7.8. Solvency. The Borrower has received consideration that is the reasonable equivalent value of the obligations and liabilities that the Borrower has incurred to the Administrative Agent and the Lenders. The Borrower now has capital sufficient to carry on its business and transactions and all business and transactions in which it is about to engage and is now solvent and able to pay its debts as they mature and the Borrower, as of the Closing Date, owns property having a value, both at fair valuation and at present fair salable value, greater than the amount required to pay the Borrower’s debts; and the Borrower is not entering into the Credit Documents with the intent to hinder, delay or defraud its creditors. For purposes of this Section 7.8, “debt” means any liability on a claim, and “claim” means (x) right to payment whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured; or (y) right to an equitable remedy for breach of performance if such breach gives rise to a payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured or unsecured.

Section 7.9. No Material Adverse Change. Since December 31, 2002, there has been no change in the financial or other condition, business, affairs or prospects of the Borrower and its Subsidiaries taken as a whole, or their properties and assets considered as an entirety, except for changes none of which, individually or in the aggregate, has had or could reasonably be expected to have, a Material Adverse Effect.

Section 7.10. Tax Returns and Payments. Each of the Borrower and each of its Subsidiaries has filed all federal income tax returns and all other material tax returns, domestic and foreign, required to be filed by it and has paid all material taxes and assessments payable by it that have become due, other than those not yet delinquent and except for those contested in good faith. The Borrower and each of its Subsidiaries has established on its books such charges, accruals and reserves in respect of taxes, assessments, fees and other governmental charges for all fiscal periods as are required by GAAP. The Borrower knows of no proposed assessment for additional federal, foreign or state taxes for any period, or of any basis therefor, which, individually or in the aggregate, taking into account such charges, accruals and reserves in respect thereof as the Borrower and its Subsidiaries have made, could reasonably be expected to have a Material Adverse Effect.

Section 7.11. Title to Properties, etc. The Borrower and each of its Subsidiaries has good and marketable title, in the case of real property, and good title (or valid Leaseholds, in the case of any leased property), in the case of all other property, to all of its properties and assets free and clear of Liens other than Permitted Liens. The interests of the Borrower and each of its Subsidiaries in the properties reflected in the most recent balance sheet referred to in Section 7.7, taken as a whole, were sufficient, in the judgment of the Borrower, as of the date of such balance sheet for purposes of the ownership and operation of the businesses conducted by the Borrower and such Subsidiaries.

Section 7.12. Lawful Operations, etc. The Borrower and each of its Subsidiaries: (i) holds all necessary federal, state and local governmental licenses, registrations, certifications, permits and authorizations necessary to conduct its business, except to the extent the failure to so hold could reasonably be expected to have a Material Adverse Effect; (ii) is in full compliance with all material requirements imposed by law, regulation or rule, whether federal, state or local, that are applicable to it, its operations, or its properties and assets, including without limitation, applicable requirements of Environmental Laws, except for any failure to obtain and maintain in effect, or noncompliance, that, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect; (iii) conduct their business in compliance with all provisions of the Fair Debt Practices Collection Act and all other applicable federal, state or local laws governing the collection of debts and neither the Borrower nor any of its Subsidiaries is in material violation of any of such laws; and (iv) are in compliance with all federal, state and local privacy laws.

Section 7.13. Environmental Matters.

(a) The Borrower and each of its Subsidiaries is in compliance with all Environmental Laws governing its business, except to the extent that any such failure to comply (together with any resulting penalties, fines or forfeitures) would not reasonably be expected to have a Material Adverse Effect.

Neither the Borrower nor any of its Subsidiaries has received written notice, or otherwise knows, that it is in any respect in noncompliance with, breach of or default under any applicable writ, order, judgment, injunction, or decree to which the Borrower or such Subsidiary is a party or that would affect the ability of the Borrower or such Subsidiary to operate any Real Property and no event has occurred and is continuing that, with the passage of time or the giving of notice or both, would constitute noncompliance, breach of or default thereunder, except in each such case, such noncompliance, breaches or defaults as would not reasonably be expected to, in the aggregate, have a Material Adverse Effect.

The Borrower, at its sole cost and expense, will cause each Additional Security Document or instruments related thereto to be duly recorded or filed in such manner and in such places as are required by law to establish, perfect, preserve and protect the Liens created thereby required to be granted pursuant to the Additional Security Document, and will pay or cause to be paid in full all taxes, fees and other charges payable in connection therewith. Furthermore, the Borrower shall cause to be delivered to the Administrative Agent such opinions of local counsel, appraisals, title insurance, surveys, environmental assessments, consents of landlords, lien waivers from landlords or mortgagees and other related documents as may be reasonably requested by the Administrative Agent or any other Agent in connection with the execution, delivery and recording of any Additional Security Document, all of which documents shall be in form and substance reasonably satisfactory to the Administrative Agent and the Administrative Agent.

(d) The Borrower will if requested by any Lender at any time, in order to meet any legal requirement applicable to such Lender, provide to the Administrative Agent and the Lenders, at the sole cost and expense of the Borrower, appraisals and other supporting documentation relating to any mortgage or deed of trust delivered as an Additional Security Document hereunder, as specified by any Lender, meeting the appraisal and other documentation requirements of the Real Estate Reform Amendments of the Financial Institution Reform, Recovery and Enforcement Act of 1989, as amended, or any other legal requirements applicable to any Lender, which in the case of any such appraisal shall be prepared by one or more valuation firms of national standing, acceptable to the Required Lenders, utilizing appraisal standards satisfying such Amendments, Act or other legal requirements.

(b) If any Event of Loss results in Net Cash Proceeds (whether in the form of insurance proceeds, a condemnation award or otherwise), a portion or all of which is required to be applied as a prepayment of the Loans or to the rebuilding or restoration of any affected property pursuant to Section 5.2, the Administrative Agent is authorized to collect such Net Cash Proceeds and, if received by any

Credit Party, the Borrower will, or will cause any applicable Credit Party, to pay over such Net Cash Proceeds to the Administrative Agent.

(ii) such Lender’s obligations under this Agreement (including, without limitation, its Commitment hereunder) shall remain unchanged,

(iii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations,

(iv) such Lender shall remain the holder of any Note for all purposes of this Agreement, and

(v) the Borrower, the Administrative Agent, and the other Lenders shall continue to deal solely and directly with the selling Lender in connection with such Lender’s rights and obligations under this Agreement, and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation, except that the participant shall be entitled to the benefits of Sections 2.6 and 2.7 of this Agreement to the extent that such Lender would be entitled to such benefits if the participation had not been entered into or sold,

and, provided further, that no Lender shall transfer, grant or sell any participation under which the participant shall have rights to approve any amendment to or waiver of this Agreement or any other Credit Document except to the extent such amendment or waiver would (w) extend the final scheduled maturity of the Loans in which such participant is participating, or reduce the rate or extend the time of payment of interest or Fees thereon (except in connection with a waiver of the applicability of any post-default increase in interest rates), or reduce the principal amount thereof, or increase such participant’s participating interest in any Commitment over the amount thereof then in effect (it being understood that a waiver of any Default or Event of Default shall not constitute a change in the terms of any such Commitment), (x) release all or any substantial portion of the Collateral, or release any guarantor from its guaranty of any of the Obligations, except strictly in accordance with the terms of the Credit Documents, or (y) consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement.

(c) Assignments by Lenders. Any Lender may assign all, or if less than all, a fixed portion, of its Loans and/or Commitment and its rights and obligations hereunder to one or more Eligible Assignees (so long as after giving effect to each such assignment, such Lender’s Commitment shall not be less than $5,000,000), each of which shall become a party to this Agreement as a Lender by execution of an Assignment Agreement, provided that

(i) except in the case (x) of an assignment of the entire remaining amount of the assigning Lender’s Loans and/or Commitment or (y) an assignment to another Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender, the aggregate amount of the Commitment (which for this purpose includes the Loans outstanding thereunder), shall not be less than $5,000,000,

(ii) in the case of any assignment to an Eligible Assignee at the time of any such assignment the Lender Register shall be deemed modified to reflect the Commitments of such new Lender and of the existing Lenders,

(iii) upon surrender of the old Notes, if any, upon request of the new Lender, new Notes will be issued, at the Borrower’s expense, to such new Lender and to the assigning Lender, such new Notes to be in conformity with the requirements of Section 2.4(d) (with appropriate modifications) to the extent needed to reflect the revised Commitments,

(iv) unless waived by the Administrative Agent, the Administrative Agent shall receive at the time of each such assignment, from the assigning or assignee Lender, the payment of a non-refundable assignment fee of $3,500,

and, provided further, that such transfer or assignment will not be effective until the Assignment Agreement in respect thereof is recorded by the Administrative Agent on the Lender Register maintained by it as provided herein.

To the extent of any assignment pursuant to this Section 12.4(c) the assigning Lender shall be relieved of its obligations hereunder with respect to its assigned Commitments.

At the time of each assignment pursuant to this Section 12.4(c) to a person that is not already a Lender hereunder and that is not a United States person (as such term is defined in Section 7701(a)(30) of the Code) for Federal income tax purposes, the respective assignee Lender shall provide to the Borrower and the Administrative Agent the appropriate Internal Revenue Service Forms (and, if applicable an Exemption Certificate) described in Section 5.4(b). To the extent that an assignment of all or any portion of a Lender’s Commitment and related outstanding Obligations pursuant to this Section 12.4(c) would, at the time of such assignment, result in increased costs under Section 2.6 from those being charged by the respective assigning Lender prior to such assignment, then the Borrower shall not be obligated to pay such increased costs (although the Borrower shall be obligated to pay any other increased costs of the type described above resulting from changes after the date of the respective assignment).

Nothing in this Section 12.4(c) shall prevent or prohibit (i) any Lender that is a bank, trust company or other financial institution from pledging its Notes or Loans to a Federal Reserve Bank in support of borrowings made by such Lender from such Federal Reserve Bank, or (ii) any Lender that is a trust, limited liability company, partnership or other investment company from pledging its Notes or Loans to a trustee or agent for the benefit of holders of certificates or debt securities issued by it. No such pledge, or any assignment pursuant to or in lieu of an enforcement of such a pledge, shall relieve the transferor Lender from its obligations hereunder.

(d) No SEC Registration or Blue Sky Compliance. Notwithstanding any other provisions of this Section 12.4, no transfer or assignment of the interests or obligations of any Lender hereunder or any grant of participation therein shall be permitted if such transfer, assignment or grant would require the Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any State.

(e) Representations of Lenders. Each Lender initially party to this Agreement hereby represents, and each person that became a Lender pursuant to an assignment permitted by this Section 12.4 will, upon its becoming party to this Agreement, represent that it is a commercial lender, other financial institution or other “accredited” investor (as defined in SEC Regulation D) that makes or acquires loans in the ordinary course of its business and that it will make or acquire Loans for its own account in the ordinary course of such business, provided that subject to the preceding Sections 12.4(b) and (c), the disposition of any promissory notes or other evidences of or interests in Indebtedness held by such Lender shall at all times be within its exclusive control.

Section 12.5. No Waiver; Remedies Cumulative. No failure or delay on the part of the Administrative Agent or any Lender in exercising any right, power or privilege hereunder or under any other Credit Document and no course of dealing between the Borrower and the Administrative Agent or any Lender shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege hereunder or under any other Credit Document preclude any other or further exercise thereof or the exercise of any other right, power or privilege hereunder or thereunder. No notice to or demand on the Borrower in any case shall entitle the Borrower to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Administrative Agent or the Lenders to any other or further action in any circumstances without notice or demand. 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 or Event of Default, regardless of whether the Administrative Agent, any Lender or the Letter of Credit Issuer may have had notice or knowledge of such Default or Event of Default at the time. The rights and remedies herein expressly provided are cumulative and not exclusive of any rights or remedies that the Administrative Agent or any Lender would otherwise have.

Section 12.6. Payments Pro Rata; Sharing of Setoffs, etc.

(a) The Administrative Agent agrees that promptly after its receipt of each payment from or on behalf of the Borrower in respect of any Obligations, it shall distribute such payment to the Lenders (other than any Lender that has expressly waived in writing its right to receive its pro rata share thereof) pro rata based upon their respective shares, if any, of the Obligations with respect to which such payment was received. As to any such payment received by the Administrative Agent prior to 1:00 P.M. (local time at the Payment Office) in funds that are immediately available on such day, the Administrative Agent will use all reasonable efforts to distribute such payment in immediately available funds on the same day to the Lenders as aforesaid.

(b) Each of the Lenders agrees that, if it should receive any amount hereunder (whether by voluntary payment, by realization upon security, by the exercise of the right of setoff or banker’s lien, by counterclaim or cross action, by the enforcement of any right under the Credit Documents, or otherwise) that is applicable to the payment of the principal of, or interest on, the Loans or Fees, of a sum that with respect to the related sum or sums received by other Lenders is in a greater proportion than the total of such Obligation then owed and due to such Lender bears to the total of such Obligation then owed and due to all of the Lenders immediately prior to such receipt, then such Lender receiving such excess payment shall purchase for cash without recourse or warranty from the other Lenders an interest in the Obligations to such Lenders in such amount as shall result in a proportional participation by all of the Lenders in such amount, provided that (i) if all or any portion of such excess amount is thereafter

recovered from such Lender, such purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest, and (ii) the provisions of this Section 12.6(b) 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 Letters of Credit to any assignee or participant pursuant to Section 12.4, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 12.6(b) 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.

(c) Notwithstanding anything to the contrary contained herein, the provisions of the preceding Sections 12.6(a) and (b) shall be subject to the express provisions of this Agreement that require, or permit, differing payments to be made to Lenders that are not Defaulting Lenders, as opposed to Defaulting Lenders.

(d) If any Lender shall fail to make any payment required to be made by it to the Administrative Agent pursuant to Section 2.3(b) or 3.4(c), then the Administrative Agent may, in its discretion (notwithstanding any contrary provision of this Agreement), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations to the Administrative Agent under such Sections until all such unsatisfied obligations are fully paid.

Section 12.7. Governing Law; Submission to Jurisdiction; Venue; Waiver of Jury Trial.

(a) THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER AND THEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF OHIO. TO THE FULLEST EXTENT PERMITTED BY LAW, THE BORROWER HEREBY UNCONDITIONALLY AND IRREVOCABLY WAIVES ANY CLAIM TO ASSERT THAT THE LAW OF ANY JURISDICTION OTHER THAN THE STATE OF OHIO GOVERNS THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS. Any legal action or proceeding with respect to this Agreement or any other Credit Document may be brought in the Court of Common Pleas of Cuyahoga County, Ohio, or of the United States for the Northern District of Ohio, and, by execution and delivery of this Agreement, the Borrower hereby irrevocably accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of the aforesaid courts. The Borrower hereby further irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to the Borrower at its address for notices pursuant to Section 12.3, such service to become effective 30 days after such mailing or at such earlier time as may be provided under applicable law. Nothing herein shall affect the right of the Administrative Agent or any Lender to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against the Borrower in any other jurisdiction.

(b) The Borrower hereby irrevocably waives any objection that it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Agreement or any other Credit Document brought in the courts referred to in Section 12.7(a) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that any such action or proceeding brought in any such court has been brought in an inconvenient forum.

(c) EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OF THE OTHER CREDIT DOCUMENTS (INCLUDING, WITHOUT LIMITATION, ANY AMENDMENTS, WAIVERS OR OTHER MODIFICATIONS RELATING TO ANY OF THE FOREGOING), OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY HERETO HEREBY (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 PARAGRAPH.

Section 12.8. Counterparts. This Agreement may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same agreement. A set of counterparts executed by all the parties hereto shall be lodged with the Borrower and the Administrative Agent.

Section 12.9. Integration. This Agreement, the other Credit Documents and any separate letter agreements with respect to fees payable to the Administrative Agent, for its own account and benefit and/or for the account, benefit of, and distribution to, the Lenders, 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 or thereof.

Section 12.12. Survival of Indemnities. All indemnities set forth herein including, without limitation, in Section 2.6, 2.7, 3.5, 5.4, 11.7 or 12.1 shall survive the execution and delivery of this Agreement and the making and repayment of Loans.

Each Lender may transfer and carry its Loans at, to or for the account of any branch office, subsidiary or affiliate of such Lender, provided that the Borrower shall not be responsible for costs arising under Section 2.6 resulting from any such transfer (other than a transfer pursuant to Section 2.8) to the extent not otherwise applicable to such Lender prior to such transfer.

Section 12.14. Confidentiality.

(a) Each of the Administrative Agent, each Letter of Credit Issuer and the Lenders agrees to maintain the confidentiality of all Confidential Information (as defined below), except that Confidential Information may be disclosed (1) 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 Confidential Information and instructed to keep such Confidential Information confidential), (2) to any direct or indirect contractual counterparty in any swap, hedge or similar agreement (or to any such contractual counterparty’s professional advisor, so long as such contractual counterparty (or such professional advisor) agrees to be bound by the provisions of this Section 12.14, (3) to the extent requested by any regulatory authority, (4) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (5) to any other party to this Agreement, (6) to any other creditor of the Borrower or any other Credit Party that is a direct or intended beneficiary of any of the Credit Documents, (7) in connection with the exercise of any remedies hereunder or under any of the other Credit Documents, or any suit, action or proceeding relating to this Agreement or any of the other Credit Documents or the enforcement of rights hereunder or thereunder, (8) subject to an agreement containing provisions substantially the same as those of this Section 12.14, to any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement, (9) with the consent of the Borrower, or (10) to the extent such Confidential Information (i) becomes publicly available other than as a result of a breach of this Section 12.14, or (ii) becomes available to the Administrative Agent, any Letter of Credit Issuer or any Lender on a non-confidential basis from a source other than the Borrower.

(b) As used in this Section, “Confidential Information” shall mean all information received from the Borrower relating to the Borrower or its business, other than any such information that is available to the Administrative Agent, any Letter of Credit Issuer or any Lender on a non-confidential basis prior to disclosure by the Borrower, provided that in the case of information received from the Borrower after the Closing Date, such information is clearly identified at the time of delivery as confidential. Notwithstanding anything herein to the contrary, “Confidential Information” shall not include, and the Administrative Agent and each Lender may disclose to any and all persons, without limitation of any kind, any information with respect to the U.S. federal income tax treatment and U.S.

federal income tax structure of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are provided to the Administrative Agent or such Lender relating to such tax treatment and tax structure.

(c) Any person required to maintain the confidentiality of Confidential Information as provided in this Section 12.14 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 Confidential Information as such person would accord to its own confidential information. The Borrower hereby agrees that the failure of the Administrative Agent, any Letter of Credit Issuer or any Lender to comply with the provisions of this Section 12.14 shall not relieve the Borrower, or any other Credit Party, of any of its obligations under this Agreement or any of the other Credit Documents.

Section 12.15. Lender Register. The Borrower hereby designates the Administrative Agent to serve as its agent, solely for purposes of this Section 12.15, to maintain a register (the “Lender Register”) on or in which it will record the names and addresses of the Lenders, and the Commitments from time to time of each of the Lenders, the Loans made to the Borrower by each of the Lenders and each repayment and prepayment in respect of the principal amount of such Loans of each such Lender. Failure to make any such recordation, or (absent manifest error) any error in such recordation, shall not affect the Borrower’s obligations in respect of such Loans. With respect to any Lender, the transfer of the Commitment of such Lender and the rights to the principal of, and interest on, any Loan made pursuant to such Commitment shall not be effective until such transfer is recorded on the Lender Register maintained by the Administrative Agent with respect to ownership of such Commitment and Loans and prior to such recordation all amounts owing to the transferor with respect to such Commitment and Loans shall remain owing to the transferor. The registration of assignment or transfer of all or part of any Commitments and Loans shall be recorded by the Administrative Agent on the Lender Register only upon the acceptance by the Administrative Agent of a properly executed and delivered Assignment Agreement pursuant to Section 12.4(c). The Borrower agrees to indemnify the Administrative Agent from and against any and all losses, claims, damages and liabilities of whatsoever nature that may be imposed on, asserted against or incurred by the Administrative Agent in performing its duties under this Section 12.15. The Lender Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

Section 12.16. Limitations on Liability of the Letter of Credit Issuers. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letters of Credit. Neither any Letter of Credit Issuer nor any of its officers or directors shall be liable or responsible for: (a) the use that may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith; (b) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged; (c) payment by a Letter of Credit Issuer against presentation of documents that do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to such Letter of Credit; or (d) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit, except that the Borrower (or a Subsidiary that is the account party in respect of the Letter of Credit in question) shall have a claim against a Letter of Credit Issuer, and a Letter of Credit Issuer shall be liable to the Borrower (or such Subsidiary), to the extent of any direct, but not consequential, damages suffered by the Borrower (or such Subsidiary) that the Borrower (or such Subsidiary) proves were caused by (i) such Letter of Credit Issuer’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (ii) such Letter of Credit Issuer’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of documentation strictly complying with the terms and conditions of such Letter of Credit. In furtherance

and not in limitation of the foregoing, a Letter of Credit Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation.

Section 12.17. General Limitation of Liability. No claim may be made by the Borrower, any Lender, the Administrative Agent, any Letter of Credit Issuer or any other person against the Administrative Agent, any Letter of Credit Issuer, or any other Lender or the Affiliates, directors, officers, employees, attorneys or agents of any of them for any damages other than actual compensatory damages in respect of any claim for breach of contract or any other theory of liability arising out of or related to the transactions contemplated by this Agreement or any of the other Credit Documents, or any act, omission or event occurring in connection therewith; and each of the Borrower, each Lender, the Administrative Agent and each Letter of Credit Issuer hereby, to the fullest extent permitted under applicable law, waives, releases and agrees not to ▇▇▇ or counterclaim upon any such claim for any special, consequential or punitive damages, whether or not accrued and whether or not known or suspected to exist in its favor.

Section 12.18. No Duty. All attorneys, accountants, appraisers, consultants and other professional persons (including the firms or other entities on behalf of which any such person may act) retained by the Administrative Agent or any Lender with respect to the transactions contemplated by the Credit Documents shall have the right to act exclusively in the interest of the Administrative Agent or such Lender, as the case may be, and shall have no duty of disclosure, duty of loyalty, duty of care, or other duty or obligation of any type or nature whatsoever to the Borrower, to any of its Subsidiaries, or to any other person, with respect to any matters within the scope of such representation or related to their activities in connection with such representation. The Borrower agrees, on behalf of itself and its Subsidiaries, not to assert any claim or counterclaim against any such persons with regard to such matters, all such claims and counterclaims, now existing or hereafter arising, whether known or unknown, foreseen or unforeseeable, being hereby waived, released and forever discharged.

Section 12.19. Lenders and Agent Not Fiduciary to Borrower, etc. The relationship among the Borrower and its Subsidiaries, on the one hand, and the Administrative Agent, each Letter of Credit Issuer and the Lenders, on the other hand, is solely that of debtor and creditor, and the Administrative Agent, each Letter of Credit Issuer and the Lenders have no fiduciary or other special relationship with the Borrower and its Subsidiaries, and no term or provision of any Credit Document, no course of dealing, no written or oral communication, or other action, shall be construed so as to deem such relationship to be other than that of debtor and creditor.

Section 12.20. Survival of Representations and Warranties. All representations and warranties herein shall survive the making of Loans and the issuance of Letters of Credit hereunder, the execution and delivery of this Agreement, the Notes and the other documents the forms of which are attached as Exhibits hereto, the issue and delivery of the Notes, any disposition thereof by any holder thereof, and any investigation made by the Administrative Agent or any Lender or any other holder of any of the Notes or on its behalf. All statements contained in any certificate or other document delivered to the Administrative Agent or any Lender or any holder of any Notes by or on behalf of the Borrower or of its Subsidiaries pursuant hereto or otherwise specifically for use in connection with the transactions contemplated hereby shall constitute representations and warranties by the Borrower hereunder, made as of the respective dates specified therein or, if no date is specified, as of the respective dates furnished to the Administrative Agent or any Lender.

Section 12.21. 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 12.22. Independence of Covenants. All covenants hereunder shall be given independent effect so that if a particular action, event, condition or circumstance is not permitted by any of such covenants, the fact that it would be permitted by an exception to, or would otherwise be within the limitations or restrictions of, another covenant, shall not avoid the occurrence of a Default or an Event of Default if such action is taken or event, condition or circumstance exists.

Section 12.23. 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 that are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) that 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 at the Base Rate to the date of repayment, shall have been received by such Lender.
