Subject to the terms of this Credit Agreement, the Borrower may borrow, repay and reborrow Revolving Loans.

2.2 Method of Borrowing for Revolving Loans.

By no later than noon (Charlotte, North Carolina time) (a) on the date of the requested borrowing of Revolving Loans that will be Base Rate Loans or (b) three Business Days prior to the date of the requested borrowing of Revolving Loans that will be Eurodollar Loans, the Borrower shall submit a written Notice of Borrowing in the form of Exhibit 2.2 to the Agent setting forth (i) the amount requested, (ii) whether such Revolving Loans shall accrue interest at the Base Rate or the Adjusted Eurodollar Rate, (iii) with respect to Revolving Loans that will be Eurodollar Loans, the Interest Period applicable thereto and (iv) certification that the Borrower has complied in all respects with Section 5.2.

Upon receipt of a Notice of Borrowing, the Agent shall promptly inform the Lenders as to the terms thereof. Each such Lender shall make its Commitment Percentage of the requested Revolving Loans available to the Agent by 2:00 p.m. (Charlotte, North Carolina time) on the date specified in the Notice of Borrowing by deposit, in Dollars, of immediately available funds at the principal offices of the Agent in Charlotte, North Carolina or at such other address as the Agent may designate in writing. The amount of the requested Revolving Loans will then be made available to the Borrower by the Agent by crediting the account of the Borrower on the books of such office of the Agent, to the extent the amount of such Revolving Loans are made available to the Agent.

No Lender shall be responsible for the failure or delay by any other Lender in its obligation to make Revolving Loans hereunder; provided, however, that the failure of any Lender to fulfill its obligations hereunder shall not relieve any other Lender of its obligations hereunder. Unless the Agent shall have been notified by any Lender prior to the date of any such Revolving Loan that such Lender does not intend to make available to the Agent its portion of the Revolving Loans to be made on such date, the Agent may assume that such Lender has made such amount available to the Agent on the date of such Revolving Loans, and the Agent in reliance upon such assumption, may (in its sole discretion but 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 Agent, the Agent shall be able to recover such corresponding amount from such Lender. If such Lender does not pay such corresponding amount forthwith upon the Agent’s demand therefor, the Agent will promptly notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Agent. The Agent shall also be entitled to recover from the 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 Agent to the Borrower to the date such corresponding amount is recovered by the Agent at a per annum rate equal to (i) from the Borrower at the applicable rate for such Revolving Loan pursuant to the Notice of Borrowing and (ii) from a Lender at the Federal Funds Rate.

Each continuation or conversion must be requested by the Borrower no later than noon (Charlotte, North Carolina time) (i) on the date for a requested conversion of a Eurodollar Loan to a Base Rate Loan or (ii) three Business Days prior to the date for a requested continuation of a Eurodollar Loan or conversion of a Base Rate Loan to a Eurodollar Loan, in each case pursuant to a written Notice of Continuation/Conversion submitted to the Agent which shall set forth (A) whether the Borrower wishes to continue or convert such Loans and (B) if the request is to continue a Eurodollar Loan or convert a Base Rate Loan to a Eurodollar Loan, the Interest Period applicable thereto.

The Borrower agrees to deliver promptly to the Agent a written confirmation of each telephonic notice signed by the chief financial officer, treasurer, secretary or assistant treasurer of the Borrower. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.5 Minimum Amounts.

Each request for a Revolving Loan or a conversion or continuation hereunder shall be subject to the following requirements: (a) each Eurodollar Loan shall be in a minimum of $5,000,000 (and in integral multiples of $1,000,000 in excess thereof), (b) each Base Rate Loan shall be in a minimum amount of the lesser of $1,000,000 (and in integral multiples of $250,000 in excess thereof) or the remaining amount available to be borrowed and (c) no more than twelve Eurodollar Loans shall be outstanding hereunder at any one time. For the purposes of this Section, all Eurodollar Loans with the same Interest Periods that begin and end on the same date shall be considered as one Eurodollar Loan, but Eurodollar Loans with different Interest Periods, even if they begin on the same date, shall be considered separate Eurodollar Loans.

(a) Ratable Reduction. Upon at least five Business Days’ notice, the Borrower shall have the right to permanently terminate or reduce the aggregate unused amount of the Revolving Loan Commitment at any time and from time to time; provided that (i) each partial reduction shall be in an aggregate amount at least equal to $10,000,000 and in integral multiples of $1,000,000 above such amount and (ii) no reduction shall be made which would reduce the Revolving Loan Commitment to an amount less than the then outstanding Loans plus the Letter of Credit Obligations. Any reduction in (or termination of) the Revolving Loan Commitment shall reduce the Revolving Loan Commitment of each Lender on a ratable basis and shall be permanent and may not be reinstated.

(b) Increase. The Borrower may request at any time and from time to time that the aggregate amount of the Revolving Loan Commitment be increased up to a maximum amount of $885,000,000; provided that (i) no increase in the Revolving Loan Commitment shall be made at a time when a Default or Event of Default shall have occurred and be continuing or would result from the requested increase, (ii) no increase in the Revolving Loan Commitment shall be made at any time after the Revolving Loan Commitment has been terminated or reduced, (iii) each partial increase shall be made in an aggregate amount at least equal to $10,000,000 and in integral multiples of $5,000,000 above such amount, (iv) no more than two such increases shall be made between the Effective Date and the Maturity Date, (v) the Borrower shall have delivered to the Agent certified resolutions of the Board of Directors of the Borrower approving such increase and borrowings in connection therewith and (vi) all of the representations and warranties set forth in Section 6 (except for those contained in Sections 6.7 and 6.10) shall be true and correct in all material respects as of the date of such request and as of the effective date of such increase. In the event of such a requested increase in the Revolving Loan Commitment, (i) each of the Lenders shall be given the opportunity to participate in the increased Revolving Loan Commitment (x) initially to the extent of such

Lender’s existing Commitment Percentage and (y) to the extent that the requested increase of the Revolving Loan Commitment is not fulfilled pursuant to the preceding clause (x), ratably in the proportion that the respective Commitment Percentages of the Lenders desiring to participate in the requested increase bear to the total of the Commitment Percentages of the increasing Lenders, and (ii) to the extent that the Lenders do not elect so to participate in such increased Revolving Loan Commitment after an opportunity to do so, then the Borrower shall consult with the Agent as to the number, identity and requested Revolving Loan Commitments of additional financial institutions that the Agent may invite to participate in the aggregate Revolving Loan Commitment. The Agent will not unreasonably refuse to so invite a commercial bank organized under the laws of the United States or of any State thereof, identified and requested by the Borrower, that has capital and surplus reasonably satisfactory to the Agent in light of the Revolving Loan Commitment which such commercial bank would assume hereunder. The Agent shall promptly notify the Borrower and the Lenders of any increase in the amount of the aggregate Revolving Loan Commitment pursuant to this Section and of the respective adjusted Revolving Loan Commitment and Commitment Percentage of each Lender after giving effect thereto. The Borrower acknowledges that, in order to maintain Loans in accordance with the Commitment Percentage of each Lender, a non-pro-rata increase in the aggregate Revolving Loan Commitment may require prepayment or funding of all or portions of certain Revolving Loans on the date of such increase (and any such prepayment or funding shall be subject to the other provisions of this Credit Agreement).

(c) Non-Ratable Reduction. The Borrower shall have the right, at any time, upon at least ten Business Days’ notice to a Defaulting Lender (with a copy to the Agent), to terminate in whole such Lender’s Revolving Loan Commitment. Such termination shall be effective, (x) with respect to such Lender’s unused Revolving Loan Commitment, on the date set forth in such notice, provided, however, that such date shall be no earlier than ten Business Days after receipt of such notice and (y) with respect to each Revolving Loan outstanding to such Lender, in the case of a Base Rate Loan, on the date set forth in such notice and, in the case of a Eurodollar Loan, on the last day of the then current Interest Period relating to such Loan. Upon termination of a Lender’s Revolving Loan Commitment under this Section 2.6(c), the Borrower will pay or cause to be paid all principal of, and interest accrued to the date of such payment on, Loans owing to such Lender and pay any accrued Commitment Fees payable to such Lender pursuant to the provisions of Section 3.4, and all other amounts payable to such Lender hereunder (including, but not limited to, any increased costs or other amounts owing under Section 4.1 or 4.2 and any indemnification for Taxes under Section 4.4); and upon such payments, the obligations of such Lender hereunder shall, by the provisions hereof, be released and discharged; provided, however, that such Lender’s rights under Sections 4.1, 4.2, 4.4 and 11.5, and its obligations under Section 10.7 shall survive such release and discharge as to matters occurring prior to such date. Subject to Section 2.6(b), the aggregate amount of the Revolving Loan Commitment of the Lenders once reduced pursuant to this Section 2.6(c) may not be reinstated.

2.7 Evidence of Debt.

(a) The Revolving Loans made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Agent in the ordinary course of business. The accounts or records maintained by the Agent and each Lender shall be

conclusive absent manifest error of the amount of the Revolving Loans made by the Lenders to the Borrower and the interest and payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Obligations. In the event of any conflict between the accounts and records maintained by any Lender and the accounts and records of the Agent in respect of such matters, the accounts and records of the Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Agent, the Borrower shall execute and deliver to such Lender (through the Agent) a duly executed promissory note of the Borrower payable to each Lender in substantially the form of Exhibit 2.7 (the “Notes”), in a principal amount equal to the amount of such Lender’s Commitment Percentage of the Revolving Loan Commitment as originally in effect.

(b) In addition to the accounts and records referred to in subsection (a), each Lender and the Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Lender of participations in Letters of Credit and Swing Line Loans. In the event of any conflict between the accounts and records maintained by the Agent and the accounts and records of any Lender in respect of such matters, the accounts and records of the Agent shall control in the absence of manifest error.

Unless the Swing Line Lender has received notice (by telephone or in writing) from the Agent (including at the request of any Lender) prior to 4:45 p.m. (Charlotte, North Carolina time) on the date of the proposed Swing Line Borrowing (A) directing the Swing Line Lender not to make such Swing Line Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.8(a), or (B) that one or more of the applicable conditions specified in Section 5.2 is not then satisfied, then, subject to the terms and conditions hereof, the Swing Line Lender will, not later than 5:30 p.m. (Charlotte, North Carolina time) on the borrowing date specified in such Swing Line Loan Notice, make the amount of its Swing Line Loan available to the Borrower at its office by crediting the account of the Borrower on the books of the Swing Line Lender in immediately available funds.

(i) The Swing Line Lender at any time in its sole discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swing Line Lender to so request on its behalf), that each Lender make a Base Rate Loan in an amount equal to such Lender’s Commitment Percentage of the amount of Swing Line Loans then outstanding. Such request shall be made in writing (which written request shall be deemed to be a Notice of Borrowing for purposes hereof) and in accordance with the requirements of Section 2.2, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans in Section 2.5, but subject to the unutilized portion of the Revolving Loan Commitments and the conditions set forth in Section 5.2. The Swing Line Lender shall furnish the Borrower with a copy of the applicable Notice of Borrowing promptly after delivering such notice to the Agent. Each Lender shall make an amount equal to its Commitment Percentage of the amount specified in such Notice of Borrowing available to the Agent in immediately available funds (and the Agent may apply Cash Collateral available with respect to the applicable Swing Line Loan) for the account of the Swing Line Lender at the Agent’s Office not later than 2:00 p.m. (Charlotte, North Carolina time) on the day specified in such Notice of Borrowing (provided such Lender receives the applicable Notice of Borrowing prior to noon (Charlotte, North Carolina time) on such day, whereupon, subject to Section 2.8(c)(ii), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The Agent shall remit the funds so received to the Swing Line Lender.

(ii) If for any reason any Swing Line Loan cannot be refinanced by such a Committed Borrowing in accordance with Section 2.8(c)(i), the request for Base Rate Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in the relevant Swing Line Loan and each Lender’s payment to the Agent for the account of

the Swing Line Lender pursuant to Section 2.8(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to the Agent for the account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.8(c) by the time specified in Section 2.8(c)(i), the Swing Line Lender shall be entitled to recover from such Lender (acting through the Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swing Line Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Loan included in the relevant Committed Borrowing or funded participation in the relevant Swing Line Loan, as the case may be. A certificate of the Swing Line Lender submitted to any Lender (through the Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swing Line Loans pursuant to this Section 2.8(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Revolving Loans pursuant to this Section 2.8(c) is subject to the conditions set forth in Section 5.2. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swing Line Loans, together with interest as provided herein.

(d) Repayment of Participations.

(i) At any time after any Lender has purchased and funded a risk participation in a Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Commitment Percentage thereof in the same funds as those received by the Swing Line Lender.

(ii) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to be returned by the Swing Line Lender under any of the circumstances described in Section 11.13 (including pursuant to any settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender its Commitment Percentage thereof on demand of the Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. The Agent will make such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this

clause shall survive the payment in full of the Obligations and the termination of this Credit Agreement.

(e) Interest for Account of Swing Line Lender. The Swing Line Lender shall be responsible for invoicing the Borrower for interest on the Swing Line Loans. Until each Lender funds its Base Rate Loan or risk participation pursuant to this Section 2.8 to refinance such Lender’s Commitment Percentage of any Swing Line Loan, interest in respect of such Commitment Percentage shall be solely for the account of the Swing Line Lender.

(f) Payments Directly to Swing Line Lender. The Borrower shall make all payments of principal and interest in respect of the Swing Line Loans directly to the Swing Line Lender.

2.9 Letters of Credit.

(a) (i) Issuance. Subject to the terms and conditions hereof and of the LOC Documents, if any, and any other terms and conditions which the relevant L/C Issuer may reasonably require, the applicable L/C Issuer shall from time to time upon request by the Borrower issue, and the Lenders shall participate in, letters of credit (the “Letters of Credit”) for the account of the Borrower; provided, however, that (A) the aggregate amount of Letter of Credit Obligations shall not at any time exceed the Letter of Credit Sublimit, (B) the sum of the aggregate amount of Letter of Credit Obligations outstanding plus the aggregate amount of Loans outstanding shall not exceed the Aggregate Commitment, (C) with respect to each individual Lender, the Lender’s outstanding Revolving Loans plus its Commitment Percentage of Swing Line Loans plus its Commitment Percentage of outstanding Letter of Credit Obligations shall not exceed such Lender’s Revolving Loan Commitment and (D) the aggregate amount of Letter of Credit Obligations in respect of Letters of Credit issued by any L/C Issuer shall not at any time exceed such LC Issuer’s L/C Issuer Limit. Each request by the Borrower for the issuance of a Letter of Credit shall be deemed to be a representation by the Borrower that the Credit Extension with respect to such requested Letter of Credit complies with the conditions set forth in the proviso to the preceding sentence. Each Letter of Credit shall be a standby letter of credit issued to support the obligations (including pension or insurance obligations), contingent or otherwise, of the Borrower or any of its Subsidiaries. Each Letter of Credit shall have a stated term not later than 10 Business Days prior to the Maturity Date unless otherwise agreed by the applicable L/C Issuer, and the participations of the Lenders as set forth in Section 2.9(e) shall in any event terminate on the Maturity Date. Each Letter of Credit shall comply with the related LOC Documents.

(ii) No L/C Issuer shall be under any obligation to issue any Letter of Credit if:

(A) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain such L/C Issuer from issuing such Letter of Credit, or any law applicable to such L/C Issuer or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over such L/C Issuer shall prohibit, or request that such L/C Issuer refrain from, the issuance of letters of credit generally

or such Letter of Credit in particular or shall impose upon such L/C Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such L/C Issuer is not otherwise compensated hereunder) not in effect on the Closing Date, or shall impose upon such L/C Issuer any unreimbursed loss, cost or expense which was not applicable on the Closing Date and which such L/C Issuer in good ▇▇▇▇▇ ▇▇▇▇▇ material to it;

(B) the issuance of such Letter of Credit would violate one or more policies of such L/C Issuer applicable to letters of credit generally;

(D) any Lender is at that time a Defaulting Lender, unless the applicable L/C Issuer has entered into arrangements, including the delivery of Cash Collateral, satisfactory to such L/C Issuer (in its sole discretion) with the Borrower or such Lender to eliminate such L/C Issuer’s actual or potential Fronting Exposure (after giving effect to Section 2.11(a)(iv)) with respect to the Defaulting Lender arising from either the Letter of Credit then proposed to be issued or that Letter of Credit and all other Letter of Credit Obligations as to which such L/C Issuer has actual or potential Fronting Exposure, as it may elect in its sole discretion.

(b) Issuance of Letters of Credit. (i) Each Letter of Credit shall be issued upon the request of the Borrower delivered to the applicable L/C Issuer (with a copy to the Agent) in the form of a Letter of Credit application, appropriately completed and signed by a Responsible Officer of the Borrower. Such Letter of Credit application must be received by the applicable L/C Issuer and the Agent not later than (i) 4:00 p.m. (Charlotte, North Carolina time) at least two Business Days prior to the proposed issuance date of a letter of credit, (ii) 4:00 p.m. (Charlotte, North Carolina time) at least two Business Days prior to the proposed amendment date for a letter of credit, or (iii) such later date and time as the Agent and such L/C Issuer may agree in a particular instance in their sole discretion. In the case of a request for an initial issuance of a Letter of Credit, such Letter of Credit application shall specify in form and detail satisfactory to the applicable L/C Issuer: (A) the proposed issuance date of the requested Letter of Credit (which shall be a Business Day); (B) the amount thereof; (C) the expiry date thereof; (D) the name and address of the beneficiary thereof; (E) the documents to be presented by such beneficiary in case of any drawing thereunder; (F) the full text of any certificate to be presented by such beneficiary in case of any drawing thereunder; (G) the purpose and nature of the requested Letter of Credit; and (H) such other matters as the applicable L/C Issuer may require. In the case of a request for an amendment of any outstanding Letter of Credit, such Letter of Credit application shall specify in form and detail satisfactory to the applicable L/C Issuer (1) the Letter of Credit to be amended; (2) the proposed date of amendment thereof (which shall be a Business Day); (3) the nature of the proposed amendment; and (4) such other matters as such L/C Issuer may require. Additionally, the Borrower shall furnish to the applicable L/C Issuer and the Agent such other documents and information pertaining to such requested Letter of Credit issuance or

amendment, including any LOC Documents, as such L/C Issuer or the Agent may require.

(ii) Promptly after receipt of any Letter of Credit application, the applicable L/C Issuer will confirm with the Agent (by telephone or in writing) that the Agent has received a copy of such Letter of Credit application from the Borrower and, if not, such L/C Issuer will provide the Agent with a copy thereof. Unless the applicable L/C Issuer has received written notice from any Lender, the Agent or the Borrower, at least one Business Day prior to the requested date of issuance of the applicable Letter of Credit, that one or more applicable conditions contained in Section 5.2 shall not then be satisfied, then, subject to the terms and conditions hereof, such L/C Issuer shall, on the requested date, issue a Letter of Credit for the account of the Borrower, in each case in accordance with such L/C Issuer’s usual and customary business practices. Immediately upon the issuance of each Letter of Credit, each Lender shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the applicable L/C Issuer a risk participation in such Letter of Credit in an amount equal to the product of such Lender’s Commitment Percentage times the amount of such Letter of Credit.

(d) Letter of Credit Fees.

(i) Letter of Credit Fees. In consideration of the issuance of Letters of Credit hereunder, the Borrower agrees to pay to the Agent for the pro rata benefit of the Lenders (based on each Lender’s Commitment Percentage), a per annum fee (the “Letter of Credit Fees”) equal to the Applicable Percentage on the average daily maximum amount available to be drawn under all Letters of Credit; provided, however, any Letter of Credit Fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the applicable L/C Issuer pursuant to this Section 2.9 or Section 2.11 shall be payable, to the maximum extent permitted by applicable Law, to the other Lenders in accordance with the upward adjustments in their respective Applicable Percentages allocable to such Letter of Credit pursuant to Section 2.11(a)(iv), with the balance of such fee, if any, payable to the applicable L/C Issuer for its own account. The Letter of Credit Fees will be payable in arrears on the first Business Day after the end of each calendar quarter (as well as on the Maturity Date) for the immediately preceding fiscal quarter (or portion thereof), beginning with the first of such dates to occur after the date of this Credit Agreement.

(ii) L/C Issuer Letter of Credit Fees. In addition to the Letter of Credit Fees payable pursuant to subsection (1) above, the Borrower shall pay to the applicable L/C Issuer for its own account, without sharing by the other Lenders, a fronting fee in an amount agreed by the Borrower and such L/C Issuer as a percentage of the outstanding face amount of each Letter of Credit payable quarterly in arrears at the same time the Letter of Credit Fees are payable plus the customary incidental and/or out of pocket charges from time to time for its services in connection with the issuance, amendment,

payment, transfer, administration, cancellation and conversion of, and drawings under, Letters of Credit.

(e) Notice and Reports. Each L/C Issuer, at least weekly and more frequently upon request, shall deliver to the Agent a complete list of all outstanding Letters of Credit issued by such L/C Issuer. The Agent will, at least monthly and more frequently upon request, provide to the Lenders a detailed report specifying the Letters of Credit which are then issued and outstanding and any activity with respect thereto which may have occurred since the date of the prior report, and including therein, among other things, the account party, the beneficiary, the face amount, and the expiry date as well as any payments or expirations which may have occurred.

(f) Participations. Each Lender, upon issuance of a Letter of Credit, shall be deemed to have purchased without recourse a risk participation from the applicable L/C Issuer in such Letter of Credit and each LOC Document related thereto and the rights and obligations arising thereunder and any collateral relating thereto, in each case in an amount equal to its Commitment Percentage of the obligations under such Letter of Credit, and shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and be obligated to pay to such L/C Issuer therefor and discharge when due, its Commitment Percentage of the obligations arising under such Letter of Credit. Without limiting the scope and nature of each Lender’s participation in any Letter of Credit, to the extent that the applicable L/C Issuer has not been reimbursed as required hereunder or under any such Letter of Credit, each such Lender shall pay to such L/C Issuer its Commitment Percentage of such unreimbursed drawing in same day funds on the day of notification by the Agent of an unreimbursed drawing pursuant to the provisions of subsection (g) hereof. The obligation of each Lender to so reimburse an L/C Issuer shall be absolute and unconditional and shall not be affected by the occurrence of a Default, an Event of Default or any other occurrence or event. Any such reimbursement shall not relieve or otherwise impair the obligation of the Borrower to reimburse the applicable L/C Issuer under any Letter of Credit, together with interest as hereinafter provided.

(g) Reimbursement. In the event of any drawing under any Letter of Credit, the applicable L/C Issuer will promptly notify the Borrower and the Agent thereof not later than 11:00 am on the date of any payment by such L/C Issuer under a Letter of Credit (each such date an “Honor Date”). If the Borrower fails to so reimburse the applicable L/C Issuer by 1:00 pm on such date, such L/C Issuer shall notify the Agent and the Agent shall promptly notify each Lender of the Honor Date, the amount of the unreimbursed drawing (the “Unreimbursed Amount”) and the amount of such Lenders’ Commitment Percentage thereof. In such event, the Borrower shall be deemed to have requested a Base Rate Loan to be disbursed on the Honor Date in a amount equal to the Unreimbursed Amount, without regard to minimum and multiples specified in Section 2.5 for the principal amount of Base Rate Loans, but subject to the amount of the unutilized portion of the Commitments and the conditions set forth in Section 5.2. If the Borrower shall fail to reimburse the applicable L/C Issuer as provided hereinabove because the conditions to the Borrower’s obtaining a Revolving Loan have not been satisfied or for any other reason, the Borrower shall be deemed to have incurred from the applicable L/C Issuer an L/C Advance in the amount of the Unreimbursed Amount of such drawing, which L/C Advance shall bear interest at a per

annum rate equal to the Adjusted Base Rate plus the Applicable Percentage plus two percent (2%). The Borrower’s reimbursement obligations hereunder shall be absolute and unconditional under all circumstances (except as expressly set forth below) irrespective of any rights of set-off, counterclaim or defense to payment the applicable account party or the Borrower may claim or have against the applicable L/C Issuer, the Agent, the Lenders, the beneficiary of the Letter of Credit drawn upon or any other Person, including without limitation, any defense based on any failure of the applicable account party or the Borrower to receive consideration or the legality, validity, regularity or unenforceability of the Letter of Credit. The applicable L/C Issuer, through the Agent, will promptly notify the Lenders of the amount of any unreimbursed drawing and any notice given by such L/C Issuer or the Agent pursuant to this Section 2.9(g) may be given by telephone if immediately confirmed in writing; provided that the lack of such an immediate confirmation shall not affect the conclusiveness or binding effect of such notice. Upon such notice, each Lender shall promptly pay to the Agent for the account of the applicable L/C Issuer, in immediately available funds, the amount of such Lender’s Commitment Percentage of such unreimbursed drawing. Such payment shall be made on the day such notice is received by such Lender from the Agent if such notice is received at or before 2:00 p.m. (Charlotte, North Carolina time), otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. If such Lender does not pay such amount to the Agent in full upon such request, such Lender shall, on demand, pay to the Agent interest on the unpaid amount during the period from the date the Lender received the notice regarding the unreimbursed drawing until the Lender pays such amount to the Agent in full at a rate per annum equal to the greater of the Federal Funds Rate and a rate determined by the applicable L/C Issuer in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by such L/C Issuer in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lenders’ Revolving Loan included in the relevant Extension of Credit. A certificate of the applicable L/C Issuer submitted to any Lender (through the Agent) with respect to any amounts owing under this Section 2.9(g) shall be conclusive absent manifest error. Each Lender’s obligation to make such payment to the Agent for the account of the applicable L/C Issuer, and the right of such L/C Issuer to receive the same, shall be absolute and unconditional, shall not be affected by any circumstance whatsoever and without regard to the termination of this Credit Agreement or the Revolving Loan Commitments hereunder, the existence of a Default or Event of Default or the acceleration of the obligations hereunder and shall be made without any offset, abatement, withholding or reduction whatsoever. Simultaneously with the making of each such payment by a Lender to an L/C Issuer, such Lender shall, automatically and without any further action on the part of such L/C Issuer or such Lender, acquire a participation in an amount equal to such payment (excluding the portion of such payment constituting interest owing to the Agent) in the related unreimbursed drawing portion of the Letter of Credit Obligation and in the interest thereon and in the related LOC Documents, and shall have a claim against the Borrower with respect thereto.

(h) Repayment with Revolving Loans. On any day on which the Borrower shall have requested, or been deemed to have requested, a Revolving Loan to reimburse a drawing under a Letter of Credit, the Agent shall give notice to the Lenders that a Revolving Loan has been requested or deemed requested in connection with a drawing under a Letter of

Credit, in which case a Revolving Loan comprised solely of Base Rate Loans (each such borrowing, a “Mandatory Borrowing”) shall be immediately made from all Lenders (without giving effect to any termination of the Revolving Loan Commitments pursuant to Section 9.1) pro rata based on each Lender’s respective Commitment Percentage and the proceeds thereof shall be paid directly to the Agent for application to the respective Letter of Credit Obligations. Each Lender hereby irrevocably agrees to make such Revolving Loans upon any such request or deemed request on account of each such Mandatory Borrowing in the amount and in the manner specified in the preceding sentence and on the same such date notwithstanding (i) the amount of Mandatory Borrowing may not comply with the minimum amount for borrowings of Revolving Loans otherwise required hereunder, (ii) whether a Default or Event of Default then exists, (iii) failure of any such request or deemed request for Revolving Loans to be made by the time otherwise required hereunder, (iv) the date of such Mandatory Borrowing, or (v) any reduction in or any termination of the Revolving Loan Commitments; provided that each Lender’s obligation to make Revolving Loans pursuant to this Section 2.9(h) is subject to the conditions set forth in Section 5.2 (other than delivery of a Notice of Borrowing). Such funding of Revolving Loans shall be made on the day notice of such Mandatory Borrowing is received by each Lender from the Agent if such notice is received at or before 2:00 p.m. (Charlotte, North Carolina time), otherwise such payment shall be made at or before 12:00 noon on the Business Day next succeeding the day such notice is received. In the event that any Mandatory Borrowing cannot for any reason be made on the date otherwise required above (including, without limitation, as a result of the commencement of a proceeding under any applicable bankruptcy law with respect to the Borrower), then each Lender hereby agrees that it shall forthwith fund (as of the date the Mandatory Borrowing would otherwise have occurred, but adjusted for any payments received from the Borrower on or after such date and prior to such purchase) its Commitment Percentage in the outstanding Letter of Credit Obligations; provided, further, that in the event any Lender shall fail to fund its Commitment Percentage on the day the Mandatory Borrowing would otherwise have occurred, then the amount of such Lender’s unfunded Commitment Percentage therein shall bear interest payable to the applicable L/C Issuer upon demand, at the rate equal to, if paid within two Business Days of such date, the Federal Funds Rate, and thereafter at a rate equal to the Base Rate. No such Extension of Credit shall relieve or otherwise impair the obligation of the Borrower to reimburse an L/C Issuer for the amount of any payment made by such L/C Issuer under any Letter of Credit, together with interest as provided herein. Until each Lender funds its Revolving Loan pursuant to this Section 2.9(g) to reimburse an L/C Issuer for any amount drawn under any Letter of Credit, interest in respect of such Lender’s Commitment Percentage of such amount shall be solely for the account of such L/C Issuer.

(i) Repayment of Participations. At any time after the applicable L/C Issuer has made a payment under any Letter of Credit and has received from any Lender such Lender’s L/C Advance in respect of such payment in accordance with Section 2.9(g), if the Agent receives for the account of such L/C Issuer any payment in respect of the related Unreimbursed Amount or interest thereon (whether directly from the Borrower or otherwise, including proceeds of Cash Collateral applied thereto by the Agent), the Agent will distribute to such Lender its Commitment Percentage thereof in the same funds as those received by the Agent. If any payment received by the Agent for the account of an L/C Issuer pursuant to Section 2.9(g) is required to be returned under any of the circumstances described in Section 11.13 (including pursuant to any settlement entered into by such L/C Issuer in its discretion),

each Lender shall pay to the Agent for the account of such L/C Issuer its Commitment Percentage thereof on demand of the Agent, plus interest thereon from the date of such demand to the date such amount is returned by such Lender, at a rate per annum equal to the Federal Funds Rate from time to time in effect. The obligations of the Lenders under this clause shall survive the payment in full of the Borrower’s obligations under, and the termination of, this Credit Agreement.

(j) Role of L/C Issuer. Each Lender and the Borrower agree that, in paying any drawing under a Letter of Credit, no L/C Issuer shall have any responsibility to obtain any document (other than any sight draft, certificates and documents expressly required by the Letter of Credit) or to ascertain or inquire as to the validity or accuracy of any such document or the authority of the Person executing or delivering any such document. None of any L/C Issuer, the Agent, any of their respective Related Parties nor any correspondent, participant or assignee of such L/C Issuer shall be liable to any Lender for (i) any action taken or omitted in connection herewith at the request or with the approval of the Lenders or the Required Lenders, as applicable; (ii) any action taken or omitted in the absence of gross negligence or willful misconduct; or (iii) the due execution, effectiveness, validity or enforceability of any document or instrument related to any Letter of Credit or LOC Documents. The Borrower hereby assumes all risks of the acts or omissions of any beneficiary or transferee with respect to its use of any Letter of Credit; provided, however, that this assumption is not intended to, and shall not, preclude the Borrower’s pursuing such rights and remedies as it may have against the beneficiary or transferee at law or under any other agreement. None of any L/C Issuer, the Agent, any of their respective Related Parties nor any correspondent, participant or assignee of any L/C Issuer shall be liable or responsible for any of the matters described in clauses (i) through (v) of Section 2.9(m); provided, however, that anything in such clauses to the contrary notwithstanding, the Borrower may have a claim against an L/C Issuer, and such L/C Issuer may be liable to the Borrower, to the extent, but only to the extent, of any direct, as opposed to consequential or exemplary, damages suffered by the Borrower which the Borrower proves were caused by such L/C Issuer’s willful misconduct or gross negligence or such L/C Issuer’s willful failure to pay under any Letter of Credit after the presentation to it by the beneficiary of a sight draft and certificate(s) strictly complying with the terms and conditions of a Letter of Credit. In furtherance and not in limitation of the foregoing, an L/C Issuer may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary, and such L/C Issuer shall not be responsible for the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason.

(k) Modification and Extension. The issuance of any supplement, modification, amendment, or extension to any Letter of Credit, for purposes hereof, shall be treated in all respects the same as the issuance of a new Letter of Credit.

(l) Applicability of ISP. The applicable L/C Issuer may have the standby Letters of Credit be subject to International Standby Practices, as published as of the date of issue by the International Chamber of Commerce (Publication No. 590 or the most recent

publication, the “ISP 98”), in which case the ISP 98 may be incorporated therein and deemed in all respects to be a part thereof.

(m) Obligations Absolute. The obligation of the Borrower to reimburse the applicable L/C Issuer for each drawing under each Letter of Credit and to repay each Extension of Credit with respect to such Letters of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Credit Agreement under all circumstances, including the following:

(i) any lack of validity or enforceability of such Letter of Credit or this Credit Agreement;

(ii) the existence of any claim, counterclaim, setoff, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), the applicable L/C Issuer or any other Person, whether in connection with this Credit Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction;

(iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit;

(iv) any payment by the applicable L/C Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or any payment made by such L/C Issuer under such Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any transferee of such Letter of Credit, including any arising in connection with any proceeding under any bankruptcy or insolvency laws; or

(v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance that might otherwise constitute a defense available to, or a discharge of, the Borrower.

(vi) The Borrower shall promptly examine a copy of each Letter of Credit that is delivered to it and, in the event of any claim of noncompliance with the Borrower’s instructions or other irregularity, the Borrower will immediately notify the applicable L/C Issuer. The Borrower shall be conclusively deemed to have waived any such claim against such L/C Issuer and its correspondents unless such notice is given as aforesaid.

(n) Responsibility of L/C Issuer. It is expressly understood and agreed as between the Lenders that the obligations of the L/C Issuers hereunder to the Lenders are only those expressly set forth in this Credit Agreement and that each L/C Issuer shall be entitled to assume that the conditions precedent set forth in Section 5 have been satisfied unless it shall have acquired actual knowledge that any such condition precedent has not been satisfied;

provided, however, that nothing set forth in this Section 2.9 shall be deemed to prejudice the right of any Lender to recover from any L/C Issuer any amounts made available by such Lender to such L/C Issuer pursuant to this Section 2.9 in the event that it is determined by a court of competent jurisdiction that the issuance of or payment with respect to a Letter of Credit constituted gross negligence or willful misconduct on the part of such L/C Issuer.

(o) Conflict with LOC Documents. In the event of any conflict between this Credit Agreement and any LOC Document, this Credit Agreement shall govern.

(p) Indemnification of L/C Issuers.

(i) In addition to its other obligations under this Credit Agreement, the Borrower hereby agrees to protect, indemnify, pay and save each L/C Issuer harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable, documented attorneys’ fees) that such L/C Issuer may incur or be subject to as a consequence, direct or indirect, of (A) the issuance of any Letter of Credit or (B) the failure of such L/C Issuer to honor a drawing under a Letter of Credit as a result of any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or governmental authority (all such acts or omissions, herein called “Government Acts”).

(ii) As between the Borrower and the L/C Issuers and the Lenders, the Borrower shall assume all risks of the acts, omissions or misuse of any Letter of Credit by the beneficiary thereof. The L/C Issuers and the Lenders shall not be responsible for (except in the case of (C) below if the applicable L/C Issuer has actual knowledge to the contrary, in which case only such L/C Issuer shall be responsible): (A) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document submitted by any party in connection with the application for and issuance of any Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; provided that such document(s) reasonably appear to conform on their face to the terms of the Letter of Credit, (B) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, that may prove to be invalid or ineffective for any reason; (C) failure of the beneficiary of a Letter of Credit to comply fully with conditions required in order to draw upon a Letter of Credit; provided that such document(s) reasonably appear to conform on their face to the terms of the Letter of Credit, (D) errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telex or otherwise, whether or not they be in cipher; (E) errors in interpretation of technical terms; (F) any loss or delay in the transmission or otherwise of any document required in order to make a drawing under a Letter of Credit or of the proceeds thereof; and (G) any consequences arising from causes beyond the control of the applicable L/C Issuer, including, without limitation, any Government Acts. None of the above shall affect, impair, or prevent the vesting of the L/C Issuers’ rights or powers hereunder.

(iii) In furtherance and extension and not in limitation of the specific provisions hereinabove set forth, any action taken or omitted by an L/C Issuer, under or

in connection with any Letter of Credit or the related certificates, if taken or omitted in good faith and not deemed to constitute gross negligence or willful misconduct, shall not put such L/C Issuer or any Lender under any resulting liability to the Borrower. It is the intention of the parties that this Credit Agreement shall be construed and applied to protect and indemnify each L/C Issuer against any and all risks involved in the issuance of the Letters of Credit, all of which risks are hereby assumed by the Borrower, including, without limitation, any and all risks of the acts or omissions, whether rightful or wrongful, of any present or future Government Acts. No L/C Issuer shall, in any way, be liable for any failure by such L/C issuer or anyone else to pay any drawing under any Letter of credit as a result of any Government Acts or any other cause beyond the control of such L/C Issuer.

(iv) Nothing in this subsection (p) is intended to limit the reimbursement obligation of the Borrower contained in this Section 2.9. The obligations of the Borrower under this subsection (p) shall survive the termination of this Credit Agreement. No act or omission of any current or prior beneficiary of a Letter of Credit shall in any way affect or impair the rights of any L/C Issuer to enforce any right, power or benefit under this Credit Agreement.

(v) Notwithstanding anything to the contrary contained in this subsection (l) or in any LOC Document, neither the Borrower nor any Lender shall have any obligation to indemnify any L/C Issuer in respect of any liability incurred by such L/C Issuer arising out of the gross negligence or willful misconduct of such L/C Issuer, as determined by a court of competent jurisdiction. Nothing in this Credit Agreement shall relieve any L/C Issuer of any liability to the Borrower or any Lender in respect of any action taken by such L/C Issuer which action constitutes gross negligence or willful misconduct of such L/C Issuer or a violation of the UCP or Uniform Commercial Code (as applicable), as determined by a court of competent jurisdiction.

(q) Letters of Credit Under the Existing Credit Agreements. Upon the Effective Date, all letters of credit issued or deemed issued by any L/C Issuer under an Existing Credit Agreement and set forth on Schedule 2.9 shall automatically be deemed Letters of Credit issued by such L/C Issuer under this Credit Agreement subject to all of the terms and conditions hereof including, among other things, that the Lenders will automatically be deemed to have purchased a participation in such letters of credit as of the Effective Date and the Borrower shall have the reimbursement obligations with respect thereto set forth in Section 2.9(g) above.

2.10 Cash Collateral.

(a) Certain Credit Support Events. In the event that any Letter of Credit remains outstanding beyond the tenth Business Day prior to the Maturity Date, the Borrower shall upon demand of the Required Lenders (or the Agent acting with the consent of the Required Lenders) either (i) Cash Collateralize the sum of the largest draft which could then or thereafter be drawn under such Letter of Credit, which sum the Agent may hold for the account of the Borrower, with interest, for the purpose of paying any draft presented, with the excess, if any, to be returned to the Borrower upon termination or expiration of such Letter of Credit or (ii) if acceptable to the applicable L/C Issuer, deliver a back-up letter of credit to the

Agent securing the Borrower’s reimbursement obligations with respect to such Letter of Credit in form and substance acceptable to the Required Lenders and from a creditworthy financial institution acceptable to the Required Lenders. Upon the request of the Agent or the applicable L/C Issuer, if such L/C Issuer has honored any full or partial drawing request under any Letter of Credit and such drawing has not been reimbursed on the date when made or refinanced with Revolving Loans, the Borrower shall immediately Cash Collateralize the then Outstanding Amount of all Letter of Credit Obligations. At any time that there shall exist a Defaulting Lender, immediately upon the request of the Agent, any L/C Issuer or the Swing Line Lender, the Borrower shall deliver to the Agent Cash Collateral in an amount sufficient to cover all Fronting Exposure (after giving effect to Section 2.11(a)(iv) and any Cash Collateral provided by the Defaulting Lender).

(b) Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked deposit accounts at Bank of America, which shall bear interest for the account of the Borrower. The Borrower, and to the extent provided by any Lender, such Lender, hereby grants to (and subjects to the control of) the Agent, for the benefit of the Agent, each L/C Issuer and the Lenders (including the Swing Line Lender), and agrees to maintain, a first priority security interest in all such cash, deposit accounts and all balances therein, and all other property so provided as collateral pursuant hereto, and in all proceeds of the foregoing, all as security for the obligations to which such Cash Collateral may be applied pursuant to Section 2.10(c). If at any time the Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Agent as herein provided, or that the total amount of such Cash Collateral is less than the applicable Fronting Exposure and other obligations secured thereby, the Borrower or the relevant Defaulting Lender will, promptly upon demand by the Agent, pay or provide to the Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency.

(c) Application. Notwithstanding anything to the contrary contained in this Credit Agreement, Cash Collateral provided under any of this Section 2.10 or Sections 2.11 or 9.2 in respect of Letters of Credit or Swing Line Loans shall be held and applied to the satisfaction of the specific Letter of Credit Obligations, Swing Line Loans, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may be provided for herein, it being agreed that Cash Collateral provided in respect of obligations of Defaulting Lenders to L/C Issuers shall be applied on a pro rata basis as set forth in Section 2.11(a)(ii).

(d) Release. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure or other obligations and not otherwise applied in accordance with Section 2.10(c) shall be released promptly following (i) the elimination of the applicable Fronting Exposure or other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender (or, as appropriate, its assignee following compliance with Section 11.6) or (ii) the Agent’s good faith determination that there exists excess Cash Collateral; provided, however, (x) that Cash Collateral furnished by or on behalf of the Borrower shall not be released during the continuance of a Default or Event of Default (and following application as provided in this Section 2.10 may be otherwise applied in accordance with Section 9.3), and (y) the Person providing Cash Collateral and the applicable

L/C Issuer or Swing Line Lender, as applicable, may agree that Cash Collateral shall not be released but instead held to support future anticipated Fronting Exposure or other obligations.

2.11 Defaulting Lenders.

(a) Adjustments. Notwithstanding anything to the contrary contained in this Credit Agreement, if any Lender becomes a Defaulting Lender, then, until such time as that Lender is no longer a Defaulting Lender, to the extent permitted by applicable Law:

(i) Waivers and Amendments. That Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Credit Agreement shall be restricted as set forth in Section 11.6.

(ii) Reallocation of Payments. Any payment of principal, interest, fees or other amounts received by the Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Section 9 or otherwise, and including any amounts made available to the Agent by that Defaulting Lender pursuant to Section 11.2), shall be applied at such time or times as may be determined by the Agent as follows: first, to the payment of any amounts owing by that Defaulting Lender to the Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by that Defaulting Lender to the L/C Issuers or Swing Line Lender hereunder; third, if so determined by the Agent or requested by any L/C Issuer or Swing Line Lender, to be held as Cash Collateral for future funding obligations of that Defaulting Lender of any participation in any Swing Line Loan or Letter of Credit; fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Credit Agreement, as determined by the Agent; fifth, if so determined by the Agent and the Borrower, to be held in an interest bearing deposit account and released in order to satisfy obligations of that Defaulting Lender to fund Loans under this Credit Agreement; sixth, to the payment of any amounts owing to the Lenders, the L/C Issuers or Swing Line Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, any L/C Issuer or Swing Line Lender against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Credit Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against that Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Credit Agreement; and eighth, to that Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Advances in respect of which that Defaulting Lender has not fully funded its appropriate share and (y) such Loans or L/C Advances were made at a time when the conditions set forth in Section 5.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Advances owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Advances owed to, that Defaulting Lender. Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section

2.11(a)(ii) shall be deemed paid to and redirected by that Defaulting Lender, and each Lender irrevocably consents hereto. Promptly (x) upon a Lender ceasing to be a Defaulting Lender in accordance with the terms of this Agreement or (y) following termination of this Agreement (including the termination of all Letters of Credit issued hereunder) and the payment of all amounts owed under this Agreement (other than unasserted contingent obligations which by their terms survive the termination of this Agreement), all amounts, if any, held in a deposit account pursuant to this Section 2.11(a) shall be returned to such Lender or Defaulting Lender, as applicable.

(iii) Certain Fees. That Defaulting Lender (x) shall not be entitled to receive any commitment fee pursuant to Section 3.4 for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender) and (y) shall be limited in its right to receive Letter of Credit Fees as provided in Section 2.9(d).

(iv) Reallocation of Applicable Percentages to Reduce Fronting Exposure. During any period in which there is a Defaulting Lender, for purposes of computing the amount of the obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit or Swing Line Loans pursuant to Sections 2.8 and 2.9, the “Applicable Percentage” of each non-Defaulting Lender shall be computed without giving effect to the Commitment of that Defaulting Lender; provided, that, (i) each such reallocation shall be given effect only if, at the date the applicable Lender becomes a Defaulting Lender, no Default or Event of Default exists; and (ii) the aggregate obligation of each non-Defaulting Lender to acquire, refinance or fund participations in Letters of Credit and Swing Line Loans shall not exceed the positive difference, if any, of (1) the Commitment of that non-Defaulting Lender minus (2) the aggregate Outstanding Amount of the Revolving Loans of that Lender.

(b) Defaulting Lender Cure. If a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, as reasonably determined by the Borrower, the Agent, Swing Line Lender and each L/C Issuer, such Defaulting Lender shall no longer be deemed to be a Defaulting Lender and the Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase that portion of outstanding Loans of the other Lenders or take such other actions as the Agent may determine to be necessary to cause the Revolving Loans and funded and unfunded participations in Letters of Credit and Swing Line Loans to be held on a pro rata basis by the Lenders in accordance with their Applicable Percentages (without giving effect to Section 2.11(a)(iv)), whereupon that Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

Section 3. PAYMENTS

3.1 Interest.

(a) Interest Rate.

(i) All Base Rate Loans shall accrue interest at the Adjusted Base Rate.

(ii) All Eurodollar Loans shall accrue interest at the Adjusted Eurodollar Rate applicable to such Eurodollar Loan.

(b) Default Rate of Interest. Upon the occurrence, and during the continuance, of an Event of Default, the principal of and, to the extent permitted by law, interest on the Loans and any other amounts owing hereunder or under the other Credit Documents shall bear interest, payable on demand, at a per annum rate equal to two percent (2%) plus the rate which would otherwise be applicable (or if no rate is applicable, then the rate for Revolving Loans that are Base Rate Loans plus two percent (2%) per annum).

3.2 Prepayments.

(a) Voluntary Prepayments. The Borrower shall have the right to prepay Loans in whole or in part from time to time without premium or penalty; provided, however, that (i) Eurodollar Loans may only be prepaid on three Business Days’ prior written notice to the Agent and any prepayment of Eurodollar Loans will be subject to Section 4.3; and (ii) each such partial prepayment of Loans shall be in the minimum principal amount of $1,000,000; provided that if less than $1,000,000 would remain outstanding after such prepayment, such prepayment shall be in the amount of the entire outstanding principal amount of the Loans. Amounts prepaid hereunder shall be applied as the Borrower may elect; provided that if the Borrower fails to specify a voluntary prepayment then such prepayment shall be applied as the Agent may direct. All voluntary prepayments shall be applied first to Swing Line Loans, then to Revolving Loans that are Base Rate Loans, and then to Revolving Loans that are Eurodollar Loans in direct order of Interest Period maturities.

(b) Mandatory Prepayments. If at any time the amount of Loans outstanding plus the Letter of Credit Obligations outstanding exceeds the Aggregate Commitment, the Borrower shall immediately make a principal payment to the Agent in the manner and in an amount such that the sum of Loans outstanding plus the Letter of Credit Obligations outstanding is less than or equal to the Aggregate Commitment. Any payments made under this Section 3.2(b) shall be subject to Section 4.3 and shall be applied first to Swing Line Loans, then to Revolving Loans that are Base Rate Loans, and then to Revolving Loans that are Eurodollar Loans in direct order of Interest Period maturities.

3.3 Payments.

(a) On the Maturity Date, the entire outstanding principal balance of all Loans and the Letter of Credit Obligations (to the extent that the Borrower has not provided cash collateral or provided a back-up letter of credit pursuant to Section 2.9(c) above), together with accrued but unpaid interest and all other sums owing under this Credit Agreement, shall be due and payable in full, unless accelerated sooner pursuant to Section 9.2.

(b) On the tenth Business Day after the making of each Swing Line Loan, the outstanding principal balance of such Swing Line Loan, together with accrued but unpaid interest and all other sums owing under this Credit Agreement, shall be due and payable in full, unless accelerated sooner pursuant to Section 9.2.

3.4 Fees.

(a) Commitment Fees. In consideration of the Revolving Loan Commitment being made available by the Lenders hereunder, the Borrower agrees to pay to the Agent, for the pro rata benefit of each Lender, a fee equal to the Applicable Percentage for Commitment Fees multiplied by the daily average of the excess of the Revolving Loan Commitment over the sum of the aggregate principal amount of the Revolving Loans plus the Letter of Credit Obligations (the “Commitment Fees”). The accrued Commitment Fees shall be due and payable in arrears on the first Business Day after the end of each calendar quarter (as well as on the final Maturity Date and on any date that the Revolving Loan Commitment is reduced) for the immediately preceding calendar quarter (or portion thereof), beginning with the first of such dates to occur after the Closing Date.

(b) Administrative Fees. The Borrower agrees to pay to the Agent, for its own account, an annual fee as agreed to between the Borrower and the Agent in the Fee Letter.

3.5 Place and Manner of Payments.

(a) All payments of principal, interest, fees, expenses and other amounts to be made by the Borrower under this Credit Agreement shall be received without setoff, deduction or counterclaim not later than 2:00 p.m.(Charlotte, North Carolina time) on the date when due in Dollars and in immediately available funds by the Agent at its offices in Charlotte, North Carolina. Unless the application of a payment is specifically directed by the Borrower (or if such application would be inconsistent with the terms hereof), the Agent shall distribute payments received from the Borrower to the Lenders in such manner as it reasonably determines in its sole discretion.

(b) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Agent for the account of the Lenders or an L/C Issuer hereunder that the Borrower will not make such payment, the Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or an L/C Issuer, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or such L/C Issuer, as the case may be, severally agrees to repay to the Agent forthwith on demand the amount so distributed to such Lender or such L/C Issuer, in immediately available funds with interest thereon, for each day from and including the date such amount is distributed to it to but

excluding the date of payment to the Agent, at the greater of the Federal Funds Rate and a rate determined by the Agent in accordance with banking industry rules on interbank compensation. A notice of the Agent to any Lender or the Borrower with respect to any amount owing under this subsection (b) shall be conclusive, absent manifest error.

3.6 Pro Rata Treatment.

Except to the extent otherwise provided herein, all Revolving Loans, each payment or prepayment of principal of any Revolving Loan, each payment of interest on the Revolving Loans, each payment of Commitment Fees, each reduction of the Revolving Loan Commitment, and each conversion or continuation of any Revolving Loans, shall be allocated pro rata among the Lenders in accordance with the respective Commitment Percentages; provided that, if any Lender shall have failed to pay its applicable pro rata share of any Revolving Loan, then any amount to which such Lender would otherwise be entitled pursuant to this Section 3.6 shall instead be payable to the Agent until the share of such Revolving Loan not funded by such Lender has been repaid; and provided, further, that in the event any amount paid to any Lender pursuant to this Section 3.6 is rescinded or must otherwise be returned by the Agent, each Lender shall, upon the request of the Agent, repay to the Agent the amount so paid to such Lender, with interest for the period commencing on the date such payment is returned by the Agent until the date the Agent receives such repayment at a rate per annum equal to, during the period to but excluding the date two Business Days after such request, the Federal Funds Rate, and thereafter, the Base Rate plus two percent (2%) per annum.

3.7 Computations of Interest and Fees.

(a) Except for Base Rate Loans, on which interest shall be computed on the basis of a 365 or 366 day year as the case may be, all computations of interest and fees hereunder shall be made on the basis of the actual number of days elapsed over a year of 360 days.

(b) It is the intent of the Lenders and the Borrower to conform to and contract in strict compliance with applicable usury law from time to time in effect. All agreements between the Lenders and the Borrower are hereby limited by the provisions of this paragraph which shall override and control all such agreements, whether now existing or hereafter arising and whether written or oral. In no way, nor in any event or contingency (including but not limited to prepayment or acceleration of the maturity of any obligation), shall the interest taken, reserved, contracted for, charged, or received under this Credit Agreement, under the Notes or otherwise, exceed the maximum nonusurious amount permissible under applicable law. If, from any possible construction of any of the Credit Documents or any other document, interest would otherwise be payable in excess of the maximum nonusurious amount, any such construction shall be subject to the provisions of this paragraph and such documents shall be automatically reduced to the maximum nonusurious amount permitted under applicable law, without the necessity of execution of any amendment or new document. If any Lender shall ever receive anything of value which is characterized as interest on the Loans under applicable law and which would, apart from this provision, be in excess of the maximum lawful amount, an amount equal to the amount which would have been excessive interest shall, without penalty, be applied to the reduction of the principal amount owing on

the Loans and not to the payment of interest, or refunded to the Borrower or the other payor thereof if and to the extent such amount which would have been excessive exceeds such unpaid principal amount of the Loans. The right to demand payment of the Loans or any other indebtedness evidenced by any of the Credit Documents does not include the right to receive any interest which has not otherwise accrued on the date of such demand, and the Lenders do not intend to charge or receive any unearned interest in the event of such demand. All interest paid or agreed to be paid to the Lenders with respect to the Loans shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full stated term (including any renewal or extension) of the Loans so that the amount of interest on account of such indebtedness does not exceed the maximum nonusurious amount permitted by applicable law.

3.8 Sharing of Payments.

Each Lender agrees that, in the event that any Lender shall obtain payment in respect of any Loan or any other obligation owing to such Lender under this Credit Agreement through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise (including, but not limited to, pursuant to the Bankruptcy Code) in excess of its pro rata share as provided for in this Credit Agreement, such Lender shall promptly purchase from the other Lenders a participation in such Loans and other obligations, in such amounts and with such other adjustments from time to time, as shall be equitable in order that all Lenders share such payment in accordance with their respective ratable shares as provided for in this Credit Agreement. Each Lender further agrees that if a payment to a Lender (which is obtained by such Lender through the exercise of a right of set-off, banker’s lien, counterclaim or otherwise) shall be rescinded or must otherwise be restored, each Lender which shall have shared the benefit of such payment shall, by repurchase of a participation theretofore sold, return its share of that benefit to each Lender whose payment shall have been rescinded or otherwise restored. The Borrower agrees that any Lender so purchasing such a participation may, to the fullest extent permitted by law, exercise all rights of payment, including set-off, banker’s lien or counterclaim, with respect to such participation as fully as if such Lender were a holder of such Loan or other obligation in the amount of such participation. Except as otherwise expressly provided in this Credit Agreement, if any Lender shall fail to remit to the Agent or any other Lender an amount payable by such Lender to the Agent or such other Lender pursuant to this Credit Agreement on the date when such amount is due, such payments shall accrue interest thereon, for each day from the date such amount is due until the day such amount is paid to the Agent or such other Lender, at a rate per annum equal to the Federal Funds Rate. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a setoff to which this Section 3.8 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders under this Section 3.8 to share in the benefits of any recovery on such secured claim.

3.9 Evidence of Debt.

(a) Each Lender shall maintain an account or accounts evidencing each Loan made by such Lender to the Borrower from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Credit Agreement.

Each Lender will make reasonable efforts to maintain the accuracy of its account or accounts and to promptly update its account or accounts from time to time, as necessary.

(b) The Agent shall maintain the Register pursuant to Section 11.3(c), and a subaccount for each Lender, in which Register and subaccounts (taken together) shall be recorded (i) the amount, type and Interest Period of each such Loan hereunder, (ii) the amount of any principal or interest due and payable or to become due and payable to each Lender hereunder and (iii) the amount of any sum received by the Agent hereunder from or for the account of the Borrower and each Lender’s share thereof. The Agent will make reasonable efforts to maintain the accuracy of the subaccounts referred to in the preceding sentence and to promptly update such subaccounts from time to time, as necessary.

(c) The entries made in the accounts, Register and subaccounts maintained pursuant to subsection (b) of this Section 3.9 (and, if consistent with the entries of the Agent, subsection (a) and the Notes issued to the Lenders) shall be prima facie evidence of the existence and amounts of the obligations of the Borrower therein recorded; provided, however, that the failure of any Lender or the Agent to maintain any such account, such Register or such subaccount, as applicable, or any error therein, shall not in any manner affect the obligation of the Borrower to repay the Loans made by such Lender in accordance with the terms hereof.

Section 4. ADDITIONAL PROVISIONS REGARDING LOANS

4.1 Pricing Provisions.

(a) Unavailability. In the event that the Agent shall have determined in good faith (i) that U.S. dollar deposits in the principal amounts requested with respect to a Eurodollar Loan are not generally available in the London interbank Eurodollar market or (ii) that reasonable means do not exist for ascertaining the Eurodollar Rate, the Agent shall, as soon as practicable thereafter, give notice of such determination to the Borrower and the Lenders. In the event of any such determination under clauses (i) or (ii) above, until the Agent shall have advised the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (A) any request by the Borrower for Eurodollar Loans shall be deemed to be a request for Base Rate Loans, (B) any request by the Borrower for conversion into or continuation of Eurodollar Loans shall be deemed to be a request for conversion into or continuation of Base Rate Loans and (C) any Revolving Loans that were to be converted or continued as Eurodollar Loans on the first day of an Interest Period shall be converted to or continued as Base Rate Loans.

(b) Change in Legality. Notwithstanding any other provision herein, if any change, after the date hereof, in any law or regulation (including the introduction of any new law or regulation) or in the interpretation thereof by any Governmental Authority charged with the administration or interpretation thereof shall make it unlawful for any Lender to make or maintain any Eurodollar Loan or to give effect to its obligations as contemplated hereby with respect to any Eurodollar Loan, then, by written notice to the Borrower and to the Agent, such Lender may:

(A) declare that Eurodollar Loans, and conversions to or continuations of Eurodollar Loans, will not thereafter be made by such Lender hereunder, whereupon any request by the Borrower for, or for conversion into or continuation of, Eurodollar Loans shall, as to such Lender only, be deemed a request for, or for conversion into or continuation of, Base Rate Loans, unless such declaration shall be subsequently withdrawn; and

(B) require that all outstanding Eurodollar Loans made by it be converted to Base Rate Loans in which event all such Eurodollar Loans shall be automatically converted to Base Rate Loans.

In the event any Lender shall exercise its rights under clause (A) or (B) above, all payments and prepayments of principal which would otherwise have been applied to repay the Eurodollar Loans that would have been made by such Lender or the converted Eurodollar Loans of such Lender shall instead be applied to repay the Base Rate Loans made by such Lenders in lieu of, or resulting from the conversion of, such Eurodollar Loans.

(c) Requirements of Law. If at any time a Lender shall incur increased costs or reductions in the amounts received or receivable hereunder with respect to the making, the commitment to make or the maintaining of any Eurodollar Loan or to the issuance or participation in Letters of Credit because of (i) any change, after the date hereof, in any applicable law, governmental rule, regulation, guideline or order (or in the interpretation or administration thereof and including the introduction of any new law or governmental rule, regulation, guideline or such order) including, without limitation, the imposition, modification or deemed applicability of any reserves, deposits or similar requirements (such as, for example, but not limited to, a change in official reserve requirements, but, in all events, excluding reserves required under Regulation D to the extent included in the computation of the Adjusted Eurodollar Rate) or (ii) other circumstances affecting the London interbank Eurodollar market; then the Borrower shall pay to such Lender promptly upon written demand therefore, accompanied by a statement in reasonable detail showing the calculation of the amount demanded, such additional amounts (in the form of an increased rate of, or a different method of calculating, interest or otherwise as such Lender may determine in its reasonable discretion) as may be required to compensate such Lender for such increased costs or reductions in amounts receivable hereunder. Each determination and calculation made by a Lender under this Section 4.1 shall, absent manifest error, be binding and conclusive on the parties hereto. Any conversions of Eurodollar Loans made pursuant to this Section 4.1 shall subject the Borrower to the payments required by Section 4.3. This Section shall survive termination of this Credit Agreement and the other Credit Documents and payment of the Loans and all other amounts payable hereunder.

(d) Cost of Funds. If the Lenders having 25% or more of the aggregate Revolving Loan Commitments determine (which determination shall be conclusive and binding upon the Borrower) that the Eurodollar Rate will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Eurodollar Loans, the Agent shall give notice thereof to the Borrower and the Lenders as soon as practicable thereafter and, upon delivery of such notice and until the Agent (upon the instruction of the such Lenders) revokes such notice, (A) any request by the

Borrower for Eurodollar Loans shall be deemed to be a request for Base Rate Loans, (B) any request by the Borrower for conversion into or continuation of Eurodollar Loans shall be deemed to be a request for conversion into or continuation of Base Rate Loans and (C) any Revolving Loans that were to be converted or continued as Eurodollar Loans on the first day of an Interest Period shall be converted to or continued as Base Rate Loans.

Failure or delay on the part of any Lender to demand compensation pursuant to this Section 4.1 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate such Lender pursuant to this Section for any increased costs or reductions incurred more than 90 days prior to the date that such Lender notifies the Borrower of the change in or in the interpretation of law or regulation giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the change in or in the interpretation of law or regulation giving rise to such increased costs or reductions is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

4.2 Capital Adequacy.

If any Lender has determined that the adoption or effectiveness, after the date hereof, of any applicable law, rule or regulation regarding capital adequacy, or any change therein (after the date hereof), 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 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, has or would have the effect of reducing the rate of return on such Lender’s (or parent corporation’s) capital or assets as a consequence of its 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 parent corporation’s) policies with respect to capital adequacy), then, upon notice from such Lender, accompanied by a statement in reasonable detail showing the calculation of the amount demanded, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. Each determination by any such Lender of amounts owing under this Section 4.2 shall, absent manifest error, be conclusive and binding on the parties hereto. This Section shall survive termination of this Credit Agreement and the other Credit Documents and payment of the Loans and all other amounts payable hereunder.

Failure or delay on the part of any Lender to demand compensation pursuant to this Section 4.2 shall not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to compensate such Lender pursuant to this Section for any increased costs or reductions incurred more than 90 days prior to the date that such Lender notifies the Borrower of the change in or in the interpretation of law or regulation giving rise to such increased costs or reductions and of such Lender’s intention to claim compensation therefor; provided further that, if the change in or in the interpretation of law or regulation giving rise to such increased costs or reductions is retroactive, then the 90-day period referred to above shall be extended to include the period of retroactive effect thereof.

4.3 Compensation.

The Borrower promises to indemnify each Lender and to hold each Lender harmless from any loss or expense which such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Credit Agreement, (b) default by the Borrower in making any prepayment of a Eurodollar Loan after the Borrower has given a notice thereof in accordance with the provisions of this Credit Agreement, (c) the making of a prepayment of Eurodollar Loans on a day which is not the last day of an Interest Period with respect thereto and (d) the payment, continuation or conversion of a Eurodollar Loan on a day which is not the last day of the Interest Period applicable thereto or the failure to repay a Eurodollar Loan when required by the terms of this Credit Agreement. Such indemnification may include an amount equal to (i) an amount of interest calculated at the Eurodollar Rate which would have accrued on the amount in question, for the period from the date of such prepayment or of such failure to borrow, convert, continue or repay to the last day of the applicable Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Eurodollar Loans provided for herein minus (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank Eurocurrency market. The agreements in this Section shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

4.4 Taxes.

(a) Except as provided below in this Section 4.4, all payments made by the Borrower under this Credit Agreement and any Notes shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any court, or governmental body, agency or other official, excluding taxes measured by or imposed upon all or a portion of the net income of any Lender or its applicable lending office, or any branch or affiliate thereof, and all franchise taxes, branch and branch profit taxes, taxes on doing business (or taxes on the capital or net worth imposed in lieu of net income taxes) of any Lender or its applicable lending office, or any branch or affiliate thereof, in each case imposed: (i) by the jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof or (ii) by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Credit Agreement or any Notes. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to an Agent or any Lender hereunder or under any Notes, (A) the amounts so payable to the Agent or such Lender shall be increased to the extent necessary to yield to the Agent or such Lender (after payment of all Non-

Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Credit Agreement and any Notes, provided, however, that the Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to timely comply with the requirements of paragraph (b) of this Section 4.4 whenever any Non-Excluded Taxes are payable by the Borrower, and (B) as promptly as possible after requested, the Borrower shall send to the Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof or other evidence of such payment as is reasonably satisfactory to the Agent or Lender (as the case may be). If the Borrower fails to pay any Non-Excluded Taxes of which it has notice when due to the appropriate taxing authority or fails to remit to the Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Agent and any Lender for any incremental Non Excluded Taxes, interest or penalties that may become payable by the Agent or any Lender as a result of any such failure. The agreements in this Section 4.4 shall survive the termination of this Credit Agreement and the payment of the Loans and all other amounts payable hereunder.

(b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall:

(i) (A) on or before the date of any payment by the Borrower under this Credit Agreement or the Notes to such Lender, deliver to the Borrower and the Agent (x) two duly completed copies of United States Internal Revenue Service Form W-8ECI or W-8BEN, or successor applicable form, as the case may be, certifying that it is entitled to receive payments under this Credit Agreement and any Notes without deduction or withholding of any United States federal income taxes and (y) an Internal Revenue Service Form W-8, or successor applicable form, certifying that it is entitled to an exemption from United States backup withholding tax;

(B) deliver to the Borrower and the Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and

(C) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Agent; or

(ii) in the case of any such Lender that is not a “bank” within the meaning of Section 881(c)(3)(A) of the Internal Revenue Code, (A) represent to the Borrower (for the benefit of the Borrower and the Agent) that it is not a bank within the meaning of Section 88l(c)(3)(A) of the Internal Revenue Code, (B) agree to furnish to the Borrower, on or before the date of any payment by the Borrower, with a copy to the Agent, two accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form certifying to such Lender’s legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of

the Internal Revenue Code with respect to payments to be made under this Credit Agreement and any Notes (and to deliver to the Borrower and the Agent two further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Agent for filing and completing such forms), and (C) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Agent) such other forms as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Credit Agreement and any Notes.

Notwithstanding the above, if any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form with respect to it and such Lender so advises the Borrower and the Agent, then such Lender shall be exempt from such requirements. Each Person that shall become a Lender or a participant of a Lender pursuant to Section 11.3 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, certifications and statements required pursuant to this subsection (b); provided that in the case of a participant of a Lender, the obligations of such participant of a Lender pursuant to this subsection (b) shall be determined as if the participant of a Lender were a Lender except that such participant of a Lender shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased.

4.5 Replacement of Lenders.

The Agent and each Lender shall use reasonable efforts to avoid or mitigate any increased cost or suspension of the availability of an interest rate under Sections 4.1 through 4.4 above to the greatest extent practicable (including transferring the Loans to another lending office of Affiliate of a Lender) unless, in the opinion of the Agent or such Lender, such efforts would be likely to have an adverse effect upon it. In the event a Lender makes a request to the Borrower for additional payments in accordance with Section 4.1, 4.2 or 4.4 or if such Lender is a Defaulting Lender, then, provided that no Default or Event of Default has occurred and is continuing at such time, the Borrower may, at its own expense (such expense to include any transfer fee payable to the Agent under Section 11.3(b) and any expense pursuant to Section 4) and in its sole discretion, require such Lender to transfer and assign in whole (but not in part), without recourse (in accordance with and subject to the terms and conditions of Section 11.3(b)), all of its interests, rights and obligations under this Credit Agreement to an Eligible Assignee which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (a) such assignment shall not conflict with any law, rule or regulation or order of any court or other Governmental Authority and (b) the Borrower or such assignee shall have paid to the assigning Lender in immediately available funds the principal of and interest accrued to the date of such payment on the portion of the Loans hereunder held by such assigning Lender and all other amounts owed to such assigning Lender hereunder, including amounts owed pursuant to Sections 4.1 through 4.4.

(i) Termination of Revolving Loan Commitments. Declare the Revolving Loan Commitments terminated whereupon the Revolving Loan Commitments shall be immediately terminated.

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

(iii) Cash Collateral. Direct the Borrower to pay (and the Borrower agrees that upon receipt of such notice, or upon the occurrence of an Event of Default under Section 9.1(e), it will immediately pay) to the Agent additional cash, to be held by the Agent, for the benefit of the Lenders, in an interest bearing cash collateral account as additional security for the Letter of Credit Obligations in respect of subsequent drawings under all then outstanding Letters of Credit in an amount equal to the maximum aggregate amount which may be drawn under all Letters of Credits then outstanding.

(iv) Enforcement of Rights. Enforce any and all rights and interests created and existing under the Credit Documents, including, without limitation, all rights of set-off.

Notwithstanding the foregoing, if an Event of Default specified in Section 9.1(e) shall occur, then the Revolving Loan Commitments shall automatically terminate and all Borrower Obligations, all accrued interest in respect thereof, all accrued and unpaid fees and other indebtedness or obligations owing to the Lenders and the Agent hereunder shall immediately become due and payable without the giving of any notice or other action by the Agent or the Lenders.

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

9.3 Allocation of Payments After Event of Default.

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

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

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

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

FOURTH, to the payment of the outstanding principal amount of the Loans and unreimbursed drawings under Letters of Credit, and to the payment or cash collateralization of the outstanding Letters of Credit Obligations, pro rata as set forth below;

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

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

In carrying out the foregoing, (a) amounts received shall be applied in the numerical order provided until exhausted prior to application to the next succeeding category; (b) each of the Lenders shall receive an amount equal to its pro rata share (based on the proportion that the then outstanding Loans, and Letter of Credit Obligations held by such Lender bears to the aggregate then outstanding Loans and Letter of Credit Obligations), of amounts available to be applied; and (c) to the extent that any amounts available for distribution pursuant to clause “FOURTH” above are attributable to the issued but undrawn amount of outstanding Letters of Credit, such amounts shall be held by the Agent in a cash collateral account and applied (x) first, to reimburse the Lenders from time to time for any drawings under such Letters of Credit and (y) then, following the expiration of all Letters of Credit, to all other obligations of the types described in clauses “FOURTH,” and “FIFTH” above in the manner provided in this Section 9.3.

The Agent shall not be responsible to any Lender for, nor have any duty to inquire into, (i) the effectiveness, genuineness, validity, enforceability, collectibility or sufficiency of this Credit Agreement, or any of the other Credit Documents, (ii) any representations, warranties, recitals or statements made herein or therein or made by the Borrower in any written or oral statement or in any financial or other statements, instruments, reports, certificates or any other documents in connection herewith or therewith furnished or made by the Agent to the Lenders or by or on behalf of the Borrower to the Agent or any Lender, (iii) the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained herein or therein or as to the use of the proceeds of the Loans or Letters of Credit or of the existence or possible existence of any Default or Event of Default or to inspect the properties, books or records of the Borrower or (iv) the satisfaction of any condition set forth in Section 5 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent. The Agent is not a trustee for the Lenders and owes no fiduciary duty to the Lenders.

10.4 Reliance on Communications.

The Agent shall be entitled to rely, and shall be fully protected in relying, upon any note, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telecopy, telex or teletype message, statement, order or other document or conversation believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower, independent accountants and other experts selected by the Agent with reasonable care). In determining compliance with any condition hereunder to the making of a Loan, or the issuance of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or an L/C Issuer, the Agent may presume that such condition is satisfactory to such Lender or such L/C Issuer unless the Agent shall have received notice to the contrary from such Lender or such L/C Issuer prior to the making of such Loan or the issuance of such Letter of Credit. The Agent may deem and treat the Lenders as the owner of its interests hereunder for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Agent in accordance with Section 11.3(b). The Agent shall be fully justified in failing or refusing to take any action under this Credit Agreement or under any of the other Credit Documents unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder or under any of the other Credit Documents in accordance with a request of the Required Lenders (or to the extent specifically provided in Section 11.6, all the Lenders) and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders (including their successors and assigns).

10.5 Notice of Default.

The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Agent has received notice from a Lender or the Borrower referring to the Credit Document, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders. The Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders.

10.6 Non-Reliance on Agent and Other Lenders.

Each Lender expressly acknowledges that neither the Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by the Agent or any affiliate thereof hereinafter taken, including any review of the affairs of the Borrower and its Subsidiaries, shall be deemed to constitute any representation or warranty by the Agent to any Lender. Each Lender represents to the Agent that it has, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower or its Subsidiaries and made its own

decision to make its Extensions of Credit hereunder and enter into this Credit Agreement. Each Lender also represents that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Credit Agreement, and to make such investigation as it deems necessary to inform itself as to the business, assets, operations, property, financial and other conditions, prospects and creditworthiness of the Borrower or its Subsidiaries. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, assets, property, financial or other conditions, prospects or creditworthiness of the Borrower or its Subsidiaries which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

10.7 Indemnification.

Each Lender agrees to indemnify the Agent in its capacity as such and each L/C Issuer in its capacity as such (in each case to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to its Commitment Percentage, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including without limitation at any time following the payment in full of the Borrower Obligations) be imposed on, incurred by or asserted against the Agent or such L/C Issuer, as the case may be, in its capacity as such in any way relating to or arising out of this Credit Agreement or the other Credit Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Agent or such L/C Issuer under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from the gross negligence or willful misconduct of the Agent or such L/C Issuer, as the case may be, or from any losses suffered by the Agent solely as a result of the Borrower’s failure to make payments as required pursuant to Section 3.4(c). If any indemnity furnished to the Agent or an L/C Issuer, as the case may be, for any purpose shall, in the opinion of the Agent or such L/C Issuer, as the case may be,, be insufficient or become impaired, the Agent or such L/C Issuer, as the case may be, may call for additional indemnity and cease, or not commence, to do the acts indemnified against until such additional indemnity is furnished. The agreements in this Section 10.7 shall survive the payment of the Borrower Obligations and all other amounts payable hereunder and under the other Credit Documents.

10.8 Agent in Its Individual Capacity.

The Agent in its individual capacity and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower and its Subsidiaries as though the Agent were not Agent hereunder. With respect to the Loans made and all Borrower Obligations owing to it, the Agent in its individual capacity shall have the same rights and powers under this Credit Agreement as any Lender and may exercise the same as

though they were not Agent, and the terms “Lender” and “Lenders” shall include the Agent in its individual capacity.

10.9 Successor Agent.

(a) The Agent may resign as the Agent upon 30 days notice to the Lenders. If the Agent resigns under this Credit Agreement, the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders which successor agent shall be approved by the Borrower. If no successor agent is appointed prior to the effective date of the resignation of the Agent, the Agent may appoint, after consulting with the Lenders and the Borrower, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the rights, powers and duties of the retiring Agent and the term “Agent” shall mean such successor agent and the retiring Agent’s appointment, powers and duties as Agent shall be terminated. After any retiring Agent’s resignation hereunder as Agent, the provisions of this Section 10 and Section 11.5 shall inure to its benefit as to any actions taken or omitted to be taken, by it while it was the Agent under this Credit Agreement. If no successor agent has accepted appointment as the Agent by the date which is 30 days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Agent hereunder until such time, if any, as the Required Lenders appoint a successor agent with the Borrower’s approval, as provided for above; provided that the Borrower’s approval shall not be required after and during the continuance of an Event of Default.

(b) Any resignation by Bank of America as Agent pursuant to this Section shall also constitute its resignation as an L/C Issuer and the Swing Line Lender. Upon the acceptance of a successor’s appointment as Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring L/C Issuer and Swing Line Lender, (b) the retiring L/C Issuer and Swing Line Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Credit Documents, and (c) the successor L/C Issuer shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring L/C Issuer to effectively assume the obligations of the retiring L/C Issuer with respect to such Letters of Credit.

10.10 Other Agents.

None of the Book Manager, the Arrangers, the Syndication Agent or the Documentation Agents, in their capacity as such, shall have any duties or obligations of any kind under this Credit Agreement.

Section 11. MISCELLANEOUS

11.1 Notices.

(a) Except as otherwise expressly provided herein, all notices and other communications shall have been duly given and shall be effective (i) when delivered, (ii) when transmitted via telecopy (or other facsimile device) or (iii) the Business Day following the day

on which the same has been delivered prepaid to a reputable national overnight air courier service, in each case to the respective parties at the address or telecopy numbers set forth on Schedule 11.1, or at such other address as such party may specify by written notice to the other parties hereto.

(b) THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” THE AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. In no event shall the Agent or any of its Related Parties (collectively, the “Agent Parties”) have any liability to the Borrower, any Lender or any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or otherwise) arising out of the Borrower’s or the Agent’s transmission of Borrower Materials through the Internet, except to the extent that such losses, claims, damages, liabilities or expenses are determined by a court of competent jurisdiction by a final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Agent Party; provided, however, that in no event shall any Agent Party have any liability to the Borrower, any Lender or any other Person for indirect, special, incidental, consequential or punitive damages (as opposed to direct or actual damages).

(c) Each Lender agrees to notify the Agent from time to time to ensure that the Agent has on record (i) an effective address, contact name, telephone number, telecopier number and electronic mail address to which notices and other communications may be sent and (ii) accurate wire instructions for such Lender.

11.2 Right of Set-Off.

In addition to any rights now or hereafter granted under applicable law or otherwise, and not by way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default and the commencement of remedies described in Section 9.2, each Lender is authorized at any time and from time to time, without presentment, demand, protest or other notice of any kind (all of which rights being hereby expressly waived), to set off and to appropriate and apply any and all deposits (general or special) and any other indebtedness at any time held or owing by such Lender (including, without limitation branches, agencies or Affiliates of such Lender wherever located) to or for the credit or the account of the Borrower against obligations and liabilities of the Borrower to the Lenders hereunder, under the Notes, the other Credit Documents or otherwise, irrespective of whether the Agent or the Lenders shall have made any demand hereunder and although such obligations, liabilities or claims, or any of them, may be contingent or unmatured. The Borrower hereby agrees that any Person purchasing a participation in the Loans and Revolving Loan Commitments hereunder pursuant to Section 11.3(c) may exercise all rights of set-off with respect to its participation interest as fully as if such Person were a Lender hereunder.

11.3 Benefit of Agreement.

(a) Generally. This Credit Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided the Borrower may not assign and transfer any of its interests without the prior written consent of the Lenders; and provided, further, that the rights of each Lender to transfer, assign or grant participations in its rights and/or obligations hereunder shall be limited as set forth below in this Section 11.3.

(b) Assignments. Each Lender may, with the consent of each L/C Issuer and the Swing Line Lender (which consent will not be unreasonably withheld or delayed), assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Credit Agreement (including, without limitation, all or a portion of its Loans, its Notes, and its Revolving Loan Commitment); provided, however, that:

(i) each such assignment shall be to an Eligible Assignee;

(ii) except in the case of an assignment to another Lender or an assignment of all of a Lender’s rights and obligations under this Credit Agreement, any such partial assignment shall be in an amount at least equal to $5,000,000 (or, if less, the remaining amount of the Revolving Loan Commitment being assigned by such Lender) and an integral multiple of $1,000,000 in excess thereof;

(iii) each such assignment by a Lender shall be of a constant and not varying, percentage of all of its rights and obligations under this Credit Agreement and the Notes;

(iv) the parties to such assignment shall execute and deliver to the Agent for its acceptance an Assignment Agreement in substantially the form of Exhibit 11.3(b), together with a processing fee (other than in connection with any assignment to an Affiliate of such Lender) from the assignor of $3,500 (unless waived by the Agent), and, if the assignee thereunder is not an existing Lender, such assignee shall deliver to the Agent such information as the Agent may request for administrative purposes; and

(v) no such assignment shall be made to (A) the Borrower or any of the Borrower’s Affiliates, (B) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B), or (C) to a natural person.

Upon execution, delivery, and acceptance of such Assignment Agreement, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Credit Agreement. Upon the consummation of any assignment pursuant to this Section 11.3(b), the assignor, the Agent and the Borrower shall make appropriate arrangements so that, if required, new Notes are issued to the assignor and the assignee. If the assignee is not incorporated under

the laws of the United States of America or a state thereof, it shall deliver to the Borrower and the Agent certification as to exemption from deduction or withholding of taxes in accordance with Section 4.4.

By executing and delivering an assignment agreement in accordance with this Section 11.3(b), the assigning Lender thereunder and the assignee thereunder shall be deemed to confirm to and agree with each other and the other parties hereto as follows: (A) such assigning Lender represents and warrants that it is legally authorized to enter into such assignment agreement and it is the legal and beneficial owner of the interest being assigned thereby free and clear of any adverse claim created by such assigning Lender and the assignee warrants that it is an Eligible Assignee; (B) except as set forth in clause (A) above, such assigning Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto, or the execution, legality, validity, enforceability, genuineness, sufficiency or value of this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto or the financial condition of the Borrower or its Subsidiaries or the performance or observance by the Borrower of any of its obligations under this Credit Agreement, any of the other Credit Documents or any other instrument or document furnished pursuant hereto or thereto; (C) such assignee represents and warrants that it is legally authorized to enter into such assignment agreement; (D) such assignee confirms that it has received a copy of this Credit Agreement, the other Credit Documents and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such assignment agreement; (E) such assignee will independently and without reliance upon the Agent, such assigning Lender or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Credit Agreement and the other Credit Documents; (F) such assignee appoints and authorizes the Agent to take such action on its behalf and to exercise such powers under this Credit Agreement or any other Credit Document as are delegated to the Agent by the terms hereof or thereof, together with such powers as are reasonably incidental thereto; and (G) such assignee agrees that it will perform in accordance with their terms all the obligations which by the terms of this Credit Agreement and the other Credit Documents are required to be performed by it as a Lender.

(c) Register. The Agent shall maintain a copy of each Assignment Agreement delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Revolving Loan Commitment of, and principal amount of the Loans owing to, each Lender and the Letters of Credit issued by each L/C Issuer from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Borrower, the Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Credit Agreement. The 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.

(d) Acceptance. Upon its receipt of an Assignment Agreement executed by the parties thereto, together with any Note subject to such assignment and payment of the processing fee, the Agent shall, if such Assignment Agreement has been completed and is in

substantially the form of Exhibit 11.3(b) hereto, (i) accept such Assignment Agreement, (ii) record the information contained therein in the Register and (iii) give prompt notice thereof to the parties thereto.

(e) Participations. Each Lender may sell participations to one or more Persons in all or a portion of its rights, obligations or rights and obligations under this Credit Agreement (including all or a portion of its Revolving Loan Commitment, its Notes and its Loans); provided, however, that (i) such Lender’s obligations under this Credit Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Sections 4.1 through 4.4, inclusive, but only to the extent that such Lender is entitled to payment or reimbursement under such Sections, and the right of set-off contained in Section 11.2 and (iv) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Credit Agreement, and such Lender shall retain the sole right to enforce the obligations of the Borrower relating to its Loans and its Notes and to approve any amendment, modification, or waiver of any provision of this Credit Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Loans or Notes, extending any scheduled principal payment date or date fixed for the payment of interest on such Loans or Notes, or extending its Revolving Loan Commitment).

(f) Nonrestricted Assignments. Notwithstanding any other provision set forth in this Credit Agreement, any Lender may at any time assign and pledge all or any portion of its Loans and its Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A and any Operating Circular issued by such Federal Reserve Bank. No such assignment shall release the assigning Lender from its obligations hereunder.

(g) Information. Any Lender may furnish any information concerning the Borrower and its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants); provided that the furnishing of such information shall be subject to the provisions of Section 11.10 below.

(h) SPC’s. Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) the option to fund all or any part of any Loan that such Granting Lender would otherwise be obligated to fund pursuant to this Credit Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to fund any Loan, (ii) if an SPC elects not to exercise such option or otherwise fails to fund all or any part of such Loan, the Granting Lender shall be obligated to fund such Loan pursuant to the terms hereof, (iii) no SPC shall have any voting rights pursuant to Section 11.6 (all such voting rights shall be retained by the Granting Lenders), (iv) with respect to notices, payments and other matters hereunder, the Borrower, the Agent and the Lenders shall not be obligated to deal with an SPC, but may limit their communications and other dealings relevant to such SPC to the applicable Granting Lender, and (v) with respect to the funding of any Loan by an SPC, the Borrower shall not have to pay any greater cost, or incur any greater expense, under the provisions of Section 4 of this Credit Agreement or otherwise, than if all Loans were funded by the applicable Granting Lender

without the involvement of an SPC. The funding of a Loan by an SPC hereunder shall utilize the Revolving Loan Commitment of the Granting Lender to the same extent that, and as if, such Loan were funded by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or payment under this Credit Agreement for which a Lender would otherwise be liable for so long as, and to the extent, the Granting Lender provides such indemnity or makes such payment. In furtherance of the foregoing, each party hereto hereby agrees (which agreements shall survive termination of this Credit Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it will not institute against, or join any other Person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. Notwithstanding anything to the contrary contained in this Credit Agreement, any SPC may disclose on a confidential basis any non-public information relating to its funding of Loans to any rating agency, commercial paper dealer or provider of any surety or guarantee to such SPC. This clause (h) may not be amended without the prior written consent of each Granting Lender, all or any part of whose Loan is being funded by an SPC at the time of such amendment.

11.4 No Waiver; Remedies Cumulative; Enforcement.

No failure or delay on the part of the 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 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. The rights and remedies provided herein are cumulative and not exclusive of any rights or remedies which the Agent or any Lender would otherwise have. 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 Agent or the Lenders to any other or further action in any circumstances without notice or demand.

Notwithstanding anything to the contrary contained herein or in any other Credit Document, the authority to enforce rights and remedies hereunder and under the other Credit Documents against the Borrower shall be vested exclusively in, and all actions and proceedings at law in connection with such enforcement shall be instituted and maintained exclusively by, the Agent in accordance with Section 9.2 for the benefit of all the Lenders and the L/C Issuers; provided, however, that the foregoing shall not prohibit (a) the Agent from exercising on its own behalf the rights and remedies that inure to its benefit (solely in its capacity as Agent) hereunder and under the other Credit Documents, (b) any L/C Issuer or the Swing Line Lender from exercising the rights and remedies that inure to its benefit (solely in its capacity as L/C Issuer or Swing Line Lender, as the case may be) hereunder and under the other Credit Documents, (c) any Lender from exercising setoff rights in accordance with Section 11.2 (subject to the terms of Section 3.6), or (d) any Lender from filing proofs of claim or appearing and filing pleadings on its own behalf during the pendency of a proceeding relative to the Borrower under any debtor relief law; and provided, further, that if at any time there is no Person acting as Agent hereunder and under the other Credit Documents, then (i) the Required Lenders shall have the rights

otherwise ascribed to the Agent pursuant to Section 9.2 and (ii) in addition to the matters set forth in clauses (b), (c) and (d) of the preceding proviso and subject to Section 3.6, any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and as authorized by the Required Lenders.

11.5 Payment of Expenses, etc.

The Borrower agrees to: (i) pay all reasonable out-of-pocket costs and expenses of the Agent and the Arrangers in connection with (A) the negotiation, preparation, execution and delivery and administration of this Credit Agreement and the other Credit Documents and the documents and instruments referred to therein (including, without limitation, legal fees of one counsel for the Agent) and (B) any amendment, waiver or consent relating hereto and thereto including, but not limited to, any such amendments, waivers or consents resulting from or related to any work-out, renegotiation or restructure relating to the performance by the Borrower under this Credit Agreement, (ii) pay all reasonable out-of-pocket costs and expenses of the Agent, each L/C Issuer and the Lenders in connection with (A) enforcement of the Credit Documents and the documents and instruments referred to therein (including, without limitation, in connection with any such enforcement, the reasonable fees and disbursements of counsel for the Agent, each L/C Issuer and each of the Lenders) and (B) any bankruptcy or insolvency proceeding of the Borrower and (iii) indemnify the Agent, the Arrangers, each L/C Issuer and each Lender, its officers, directors, employees, representatives, affiliates and agents from and hold each of them harmless against any and all losses, liabilities, claims, damages or expenses incurred by any of them as a result of, or arising out of, or in any way related to, or by reason of, any investigation, litigation or other proceeding (whether or not the Agent, the Arrangers, any L/C Issuer or any Lender is a party thereto) related to the entering into and/or performance of any Credit Document or the use of proceeds of any Loans (including other extensions of credit) hereunder or the consummation of any other transactions contemplated in any Credit Document, including, without limitation, the reasonable fees and disbursements of counsel incurred in connection with any such investigation, litigation or other proceeding (but excluding any such losses, liabilities, claims, damages or expenses to the extent incurred by reason of gross negligence or willful misconduct on the part of the Person to be indemnified or such Person’s employer, employee or co-employee); provided that the foregoing indemnity by the Borrower shall not extend to disputes solely among the Lenders or litigation commenced by the Borrower which (a) seeks enforcement of any of the Borrower’s rights hereunder and (b) is determined in a final judgment adverse to the Agent and the Lenders. The agreements in this Section 11.5 shall survive the payment of the Borrower Obligations and all other amounts payable hereunder and under the other Credit Documents.

11.6 Amendments, Waivers and Consents.

Neither this Credit Agreement, nor any other Credit Document nor any of the terms hereof or thereof may be amended, changed, waived, discharged or terminated unless such amendment, change, waiver, discharge or termination is in writing and signed by the Required Lenders and the Borrower, and acknowledged by the Agent; provided that no such amendment, change, waiver, discharge or termination shall without the consent of each Lender:

(a) extend the Maturity Date, or postpone or extend the time for any payment or prepayment of principal;

(b) reduce the rate or extend the time of payment of interest (other than as a result of waiving the applicability of any post-default increase in interest rates) thereon or fees or other amounts payable hereunder;

(d) increase or extend the Revolving Loan Commitment of a Lender (it being understood and agreed that a waiver of any Default or Event of Default shall not constitute a change in the terms of any Revolving Loan Commitment of any Lender);

(e) release the Borrower from its obligations under the Credit Documents;

(f) amend, modify or waive any provision of this Section 11.6 or Section 3.6, 3.8, 4.1, 4.2, 4.3, 4.4, 9.1(a), 11.2, 11.3 or 11.5;

(g) reduce any percentage specified in, or otherwise modify, the definition of Required Lenders; or

(h) consent to the assignment or transfer by the Borrower of any of its rights and obligations under (or in respect of) the Credit Documents.

No provision of Section 2.9 or Section 10 may be amended or modified without the consent of the Agent.

No amendment, waiver or consent shall, unless in writing and signed by each L/C Issuer, adversely affect the rights or obligations of the L/C Issuers in their capacities as such under this Credit Agreement.

No amendment, waiver or consent shall, unless in writing and signed by the Swing Line Lender, affect the rights or obligations of the Swing Line Lender in its capacity as such under this Credit Agreement.

Notwithstanding the fact that the consent of all the Lenders is required in certain circumstances as set forth above, each Lender is entitled to vote as such Lender sees fit on any reorganization plan that affects the Loans, and each Lender acknowledges that the provisions of Section 1126(c) of the Bankruptcy Code supersedes the unanimous consent provisions set forth herein.

Each Lender understands and agrees that if such Lender is a Defaulting Lender then it shall not be entitled to vote on any matter requiring the consent of the Required Lenders or to object to any matter requiring the consent of all the Lenders (except that (x) an increase or extension of the Commitment(s) of such Defaulting Lender, (y) any reduction of the amount of principal or interest owed to such Defaulting Lender and (z) or any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall, in each case, require the

consent of such Defaulting Lender); provided, however, that all other benefits and obligations under the Credit Documents shall apply to such Defaulting Lender.

11.7 Counterparts/Telecopy.

This Credit Agreement may be executed in any number of counterparts, each of which where so executed and delivered shall be an original, but all of which shall constitute one and the same instrument. Delivery of executed counterparts by telecopy shall be as effective as an original and shall constitute a representation that an original will be delivered.

11.8 Headings.

The headings of the sections and subsections hereof are provided for convenience only and shall not in any way affect the meaning or construction of any provision of this Credit Agreement.

11.9 Survival of Indemnification and Representations and Warranties.

11.17 USA Patriot Act Notification.

The following notification is provided to the Borrower pursuant to Section 326 of the USA Patriot Act of 2001, 31 U.S.C. Section 5318:

IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering activities, Federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. What this means for the Borrower: When the Borrower opens an account, if the Borrower is an individual, the Agent and the Lenders will ask for the Borrower’s name, residential address, tax identification number, date of birth, and other information that will allow the Agent and the Lenders to identify the Borrower, and, if the Borrower is not an individual, the Agent and the Lenders will ask for the Borrower’s name, tax identification number, business address, and other information that will allow the Agent and the Lenders to identify the Borrower. The Agent and the Lenders may also ask, if the Borrower is an individual, to see the Borrower’s driver’s license or other identifying documents, and, if the Borrower is not an individual, to see the Borrower’s legal organizational documents or other identifying documents.

11.18 Entirety.

This Credit Agreement together with the other Credit Documents represent the entire agreement of the parties hereto and thereto, and supersede all prior agreements and understandings, oral or written, if any, including any commitment letters or correspondence relating to the Credit Documents or the transactions contemplated herein and therein.

11.19 No Advisory or Fiduciary Responsibility.

In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Credit Document), the Borrower acknowledges and agrees that: (i) (A) the arranging and other services regarding this Credit Agreement provided by the Agent, the Lenders and the Arrangers are arm’s-length commercial transactions between the Borrower and its Affiliates, on the one hand, and the Agent, the Lenders and the Arrangers, on the other hand, (B) the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent it has deemed appropriate, and (C) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Credit Documents; (ii) (A) the Agent, each Lender and each Arranger is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any of its Affiliates, or any other Person and (B) neither the Agent nor any Lender nor any Arranger has any obligation to the Borrower or any of its Affiliates with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Credit Documents; and (iii) the Agent, the Lenders and the Arrangers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Borrower and its Affiliates, and neither the Agent nor any Lender nor any Arranger has any obligation to disclose any of such interests to the Borrower or its Affiliates. To the fullest extent permitted by law, the Borrower hereby waives and releases any claims that it may have against the Agent, the Lenders and the Arrangers with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.
