REVOLVING CREDIT FACILITY

SECTION 2.1 Revolving Credit Loans. Subject to the terms and conditions of this Agreement and the other Loan Documents, and in reliance upon the representations and warranties set forth herein, each Revolving Credit Lender severally agrees to make Revolving Credit Loans to the Borrower from time to time from the Closing Date through, but not including, the Maturity Date as requested by the Borrower in accordance with the terms of Section 2.3; provided, that (a) the Revolving Credit Outstandings shall not exceed the Revolving Credit Commitment and (b) the principal amount of outstanding Revolving Credit Loans from any Revolving Credit Lender plus such Revolving Credit Lender’s Revolving Credit Commitment Percentage of outstanding L/C Obligations and outstanding Swingline Loans shall not at any time exceed such Revolving Credit Lender’s Revolving Credit Commitment. Each Revolving Credit Loan by a Revolving Credit Lender shall be in a principal amount equal to such Revolving Credit Lender’s Revolving Credit Commitment Percentage of the aggregate principal amount of Revolving Credit Loans requested on such occasion. Subject to the terms and conditions hereof, the Borrower may borrow, repay and reborrow Revolving Credit Loans hereunder until the Maturity Date.

SECTION 2.2 Swingline Loans.

(a) Availability. Subject to the terms and conditions of this Agreement, the Swingline Lender agrees to make Swingline Loans to the Borrower from time to time from the Closing Date through, but not including, the Maturity Date; provided, that the aggregate principal amount of all outstanding Swingline Loans (after giving effect to any amount requested), shall not exceed the lesser of (i) the Revolving Credit Commitment less the sum of all outstanding Revolving Credit Loans and the L/C Obligations and (ii) the Swingline Commitment.

(b) Refunding.

(i) Swingline Loans shall be refunded by the Revolving Credit Lenders on demand by the Swingline Lender. Such refundings shall be made by the Revolving Credit Lenders in accordance with their respective Revolving Credit Commitment Percentages and shall thereafter be reflected as Revolving Credit Loans of the Revolving Credit Lenders on the books and records of the Administrative Agent. Each Revolving Credit Lender shall fund its respective Revolving Credit Commitment Percentage of Revolving Credit Loans as required to repay Swingline Loans outstanding to the Swingline Lender upon demand by the Swingline Lender but in no event later than 1:00 p.m. on the next succeeding Business Day after such demand is made. No Revolving Credit Lender’s obligation to fund its respective Revolving Credit Commitment Percentage of a Swingline Loan shall be affected by any other Revolving Credit Lender’s failure to fund its Revolving Credit Commitment Percentage of a Swingline Loan, nor shall any Revolving Credit Lender’s Revolving Credit Commitment Percentage be increased as a result of any such failure of any other Revolving Credit Lender to fund its Revolving Credit Commitment Percentage of a Swingline Loan.

(ii) The Borrower shall pay to the Swingline Lender on demand the amount of such Swingline Loans to the extent amounts received from the Revolving Credit Lenders are not sufficient to repay in full the outstanding Swingline Loans requested or required to be refunded. In addition, the Borrower hereby authorizes the Administrative Agent to charge any account maintained by the Borrower with the Swingline Lender (up to the amount available therein) in order to immediately pay the Swingline Lender the amount of such Swingline Loans to the extent amounts received from the Revolving Credit Lenders are not sufficient to repay in full the outstanding Swingline Loans requested or required to be

-28-

refunded. If any portion of any such amount paid to the Swingline Lender shall be recovered by or on behalf of the Borrower from the Swingline Lender in bankruptcy or otherwise, the loss of the amount so recovered shall be ratably shared among all the Revolving Credit Lenders in accordance with their respective Revolving Credit Commitment Percentages (unless the amounts so recovered by or on behalf of the Borrower pertain to a Swingline Loan extended after the occurrence and during the continuance of an Event of Default of which the Administrative Agent has received notice in the manner required pursuant to Section 12.1 and which such Event of Default has not been waived by the Required Lenders or the Lenders, as applicable).

(iii) Each Revolving Credit Lender acknowledges and agrees that its obligation to refund Swingline Loans in accordance with the terms of this Section 2.2 is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Article V. Further, each Revolving Credit Lender agrees and acknowledges that if prior to the refunding of any outstanding Swingline Loans pursuant to this Section 2.2, one of the events described in Section 10.1(h) or (i) shall have occurred, each Revolving Credit Lender will, on the date the applicable Revolving Credit Loan would have been made, purchase an undivided participating interest in the Swingline Loan to be refunded in an amount equal to its Revolving Credit Commitment Percentage of the aggregate amount of such Swingline Loan. Each Revolving Credit Lender will immediately transfer to the Swingline Lender, in immediately available funds, the amount of its participation and upon receipt thereof the Swingline Lender will deliver to such Revolving Credit Lender a certificate evidencing such participation dated the date of receipt of such funds and for such amount. Whenever, at any time after the Swingline Lender has received from any Revolving Credit Lender such Revolving Credit Lender’s participating interest in a Swingline Loan, the Swingline Lender receives any payment on account thereof, the Swingline Lender will distribute to such Revolving Credit Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Revolving Credit Lender’s participating interest was outstanding and funded).

(c) Defaulting Lenders. Notwithstanding anything to the contrary contained in this Section 2.2, the Swingline Lender shall not be obligated to make any Swingline Loans at a time when any other Revolving Credit Lender is a Defaulting Lender, unless the Swingline Lender has entered into arrangements satisfactory to it to eliminate the Swingline Lender’s risk with respect to any such Defaulting Lender’s funding obligations hereunder, including by cash collateralizing such Defaulting Lender’s pro rata portion of the applicable outstanding Swingline Loans. On demand by the Swingline Lender or the Administrative Agent from time to time, the Borrower shall cash collateralize each Defaulting Lender’s pro rata portion of the outstanding Swingline Loans on terms reasonably satisfactory to the Administrative Agent and the Swingline Lender. Any such cash collateral shall be deposited in a separate account with the Administrative Agent, subject to the exclusive dominion and control of the Administrative Agent, as collateral (solely for the benefit of the Swingline Lender) for the payment and performance of each Defaulting Lender’s pro rata portion of outstanding Swingline Loans. Moneys in such account shall be applied by the Administrative Agent to reimburse the Swingline Lender immediately for each Defaulting Lender’s pro rata portion of any Swingline Loans which have not otherwise been refunded by the Borrower or such Defaulting Lender pursuant to the terms of this Section 2.2.

SECTION 2.3 Procedure for Advances of Revolving Credit Loans and Swingline Loans.

Subject to Section 4.7 hereof, the Administrative Agent shall not be obligated to disburse the portion of the proceeds of any Revolving Credit Loan requested pursuant to this Section 2.3 to the extent that any Revolving Credit Lender has not made available to the Administrative Agent its Revolving Credit Commitment Percentage of such Loan. Revolving Credit Loans to be made for the purpose of refunding Swingline Loans shall be made by the Revolving Credit Lenders as provided in Section 2.2(b).

If at any time the Revolving Credit Outstandings exceed the Revolving Credit Commitment, the Borrower agrees to repay immediately upon notice from the Administrative Agent, by payment to the Administrative Agent for the account of the Revolving Credit Lenders, Extensions of Credit in an amount equal to such excess with each such repayment applied first, to the principal amount of outstanding Swingline Loans, second to the principal amount of outstanding Revolving Credit Loans and third, with respect to any Letters of Credit then outstanding, a payment of cash collateral into a cash collateral account opened by the Administrative Agent, for the benefit of the Revolving Credit Lenders, in an amount equal to the aggregate L/C Obligations then outstanding (such cash collateral to be applied in accordance with Section 10.2(b)).

(c) Optional Prepayments. The Borrower may at any time and from time to time prepay Revolving Credit Loans and Swingline Loans, in whole or in part, with irrevocable prior written notice to the Administrative Agent substantially in the form attached as Exhibit D (a “Notice of Prepayment”)

Upon receipt of such notice, the Administrative Agent shall promptly notify each Revolving Credit Lender. If any such notice is given, the amount specified in such notice shall be due and payable on the date set forth in such notice. Partial prepayments shall be (A) with respect to Base Rate Loans (other than Swingline Loans), in an aggregate amount of $3,000,000 or a whole multiple of $1,000,000 in excess thereof, (B) with respect to LIBOR Rate Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof and (C) with respect to Swingline Loans, $100,000 or a whole multiple of $100,000 in excess thereof.

(e) Hedging Agreements. No repayment or prepayment pursuant to this Section 2.4 shall affect any of the Borrower’s obligations under any Hedging Agreement.

SECTION 2.5 Permanent Reduction of the Revolving Credit Commitment.

(a) Voluntary Reduction. The Borrower shall have the right at any time and from time to time, upon at least five (5) Business Days prior written notice to the Administrative Agent, to permanently reduce, without premium or penalty, (i) the entire Revolving Credit Commitment at any time or (ii) portions of the Revolving Credit Commitment, from time to time, in an aggregate principal amount not less than $3,000,000 or any whole multiple of $1,000,000 in excess thereof. Any reduction of the Revolving Credit Commitment shall be applied to the Revolving Credit Commitment of each Revolving Credit Lender according to its Revolving Credit Commitment Percentage. All commitment fees accrued until the effective date of any termination of the Revolving Credit Commitment shall be paid on the effective date of such termination.

(b) Corresponding Payment. Each permanent reduction pursuant to Section 2.5(a) shall be accompanied by a payment of principal sufficient to reduce the aggregate outstanding Revolving Credit Loans, Swingline Loans and L/C Obligations, as applicable, after such reduction to the Revolving Credit Commitment as so reduced and if the Revolving Credit Commitment as so reduced is less than the aggregate amount of all outstanding Letters of Credit, the Borrower shall be required to deposit cash collateral in a cash collateral account opened by the Administrative Agent in an amount equal to the aggregate L/C Obligations then outstanding. Such cash collateral shall be applied in accordance with Section 10.2(b). Any reduction of the Revolving Credit Commitment to zero shall be accompanied by payment of all outstanding Revolving Credit Loans and Swingline Loans (and furnishing of cash collateral satisfactory to the Administrative Agent for all L/C Obligations) and shall result in the termination of the Revolving Credit Commitment and the Swingline Commitment and the Revolver Facility. If the reduction of the Revolving Credit Commitment requires the repayment of any LIBOR Rate Loan, such repayment shall be accompanied by any amount required to be paid pursuant to Section 4.9 hereof.

SECTION 2.6 Mandatory Prepayments. The Loans shall be prepaid as follows:

(a) Debt Issuances. The Borrower shall prepay the outstanding principal amount of Loans in an amount equal to one hundred percent (100%) of the aggregate Net Cash Proceeds from any Debt Issuance

References herein to “issue” and derivations thereof with respect to Letters of Credit shall also include extensions or modifications of any outstanding Letters of Credit, unless the context otherwise requires. As of the Closing Date, each of the Existing Letters of Credit shall constitute, for all purposes of this Agreement and the other Loan Documents, a Letter of Credit issued and outstanding hereunder.

(b) Defaulting Lenders. Notwithstanding anything to the contrary contained in this Section 3.1, the Issuing Bank shall not be obligated to issue any Letter of Credit at a time when any other Lender is a Defaulting Lender, unless the Issuing Bank has entered into arrangements satisfactory to it to eliminate the Issuing Bank’s risk with respect to any such Defaulting Lender’s reimbursement obligations hereunder, including by cash collateralizing such Defaulting Lender’s Commitment Percentage of the liability with respect to such Letter of Credit. On demand by the Issuing Bank or the Administrative Agent from time to time, the Borrowers shall cash collateralize each Defaulting Lender’s Revolving Credit Commitment Percentage of the outstanding Letter of Credit Obligations on terms reasonably satisfactory to the Administrative Agent and the Issuing Bank. Any such cash collateral shall be deposited in a separate account with the Administrative Agent, subject to the exclusive dominion and control of the Administrative Agent, as collateral (solely for the benefit of the Issuing Bank) for the payment and performance of each Defaulting Lender’s Revolving Credit Commitment Percentage of outstanding Swingline Loans. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank immediately for each Defaulting Lender’s Revolving Credit Commitment Percentage of any drawing under any Letter of Credit which has not otherwise been reimbursed by the Borrowers or such Defaulting Lender pursuant to the terms of this Section 3.1.

SECTION 3.2 Procedure for Issuance of Letters of Credit. The Borrower may from time to time request that the Issuing Bank issue a Letter of Credit by delivering to the Issuing Bank at the Administrative Agent’s Office a Letter of Credit Agreement therefor, completed to the satisfaction of the Issuing Bank, and such other certificates, documents and other papers and information as the Issuing Bank may request.

The Issuing Bank shall promptly furnish to the Borrower a copy of such Letter of Credit and promptly notify each Revolving Credit Lender of the issuance

-33-

and upon request by any Revolving Credit Lender, furnish to such Lender a copy of such Letter of Credit and the amount of such Revolving Credit Lender’s participation therein.

SECTION 3.3 Commissions and Other Charges.

(a) Letter of Credit Commissions. The Borrower shall pay to the Administrative Agent, for the account of the Issuing Bank and the L/C Participants, a letter of credit commission with respect to each Letter of Credit in the amount equal to the face amount of such Letter of Credit multiplied by the Applicable Margin with respect to Revolving Credit Loans that are LIBOR Rate Loans (determined on a per annum basis), provided that each Letter of Credit bear a minimum commission of $500. Such commission shall be payable quarterly in arrears on the last Business Day of each calendar quarter, on the Maturity Date and thereafter on demand of the Administrative Agent. The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Bank and the L/C Participants all commissions received pursuant to this Section 3.3 in accordance with their respective Revolving Credit Commitment Percentages.

(b) Fronting Fee. In addition to the foregoing commission, the Borrower shall pay to the Administrative Agent, for the account of the Issuing Bank, a fronting fee with respect to each Letter of Credit as set forth in the Commitment and Engagement Letter. Such issuance fee shall be payable quarterly in arrears on the last Business Day of each calendar quarter commencing with the first such date to occur after the issuance of such Letter of Credit, on the Maturity Date and thereafter on demand of the Administrative Agent.

(c) Other Costs. In addition to the foregoing fees and commissions, the Borrower shall pay or reimburse the Issuing Bank for such normal and customary costs and expenses as are incurred or charged by the Issuing Bank in issuing, effecting payment under, amending or otherwise administering any Letter of Credit.

SECTION 3.4 L/C Participations.

(a) The Issuing Bank irrevocably agrees to grant and hereby grants to each L/C Participant, and, to induce the Issuing Bank to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Bank, on the terms and conditions hereinafter stated, for such L/C Participant’s own account and risk an undivided interest equal to such L/C Participant’s Revolving Credit Commitment Percentage in the Issuing Bank’s obligations and rights under and in respect of each Letter of Credit issued hereunder and the amount of each draft paid by the Issuing Bank thereunder. Each L/C Participant unconditionally and irrevocably agrees with the Issuing Bank that, if a draft is paid under any Letter of Credit for which the Issuing Bank is not reimbursed in full by the Borrower through a Revolving Credit Loan or otherwise in accordance with the terms of this Agreement, such L/C Participant shall pay to the Issuing Bank upon demand at the Issuing Bank’s address for notices specified herein an amount equal to such L/C Participant’s Revolving Credit Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed.

(b) Upon becoming aware of any amount required to be paid by any L/C Participant to the Issuing Bank pursuant to Section 3.4(a) in respect of any unreimbursed portion of any payment made by the Issuing Bank under any Letter of Credit, the Issuing Bank shall notify each L/C Participant of the amount and due date of such required payment and such L/C Participant shall pay to the Issuing Bank the amount specified on the applicable due date. If any such amount is paid to the Issuing Bank after the date such payment is due, such L/C Participant shall pay to the Issuing Bank on demand, in addition to such amount, the product of (i) such amount, times (ii) the daily average Federal Funds Rate as determined by

-34-

the Administrative Agent during the period from and including the date such payment is due to the date on which such payment is immediately available to the Issuing Bank, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. A certificate of the Issuing Bank with respect to any amounts owing under this Section 3.4 shall be conclusive in the absence of manifest error. With respect to payment to the Issuing Bank of the unreimbursed amounts described in this Section 3.4, if the L/C Participants receive notice that any such payment is due (A) prior to 1:00 p.m. on any Business Day, such payment shall be due that Business Day, and (B) after 1:00 p.m. on any Business Day, such payment shall be due on the following Business Day.

(c) Whenever, at any time after the Issuing Bank has made payment under any Letter of Credit and has received from any L/C Participant its Revolving Credit Commitment Percentage of such payment in accordance with this Section 3.4, the Issuing Bank receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise), or any payment of interest on account thereof, the Issuing Bank will distribute to such L/C Participant its pro rata share thereof; provided, that in the event that any such payment received by the Issuing Bank shall be required to be returned by the Issuing Bank, such L/C Participant shall return to the Issuing Bank the portion thereof previously distributed by the Issuing Bank to it.

SECTION 3.5 Reimbursement Obligation of the Borrower. In the event of any drawing under any Letter of Credit, the Borrower agrees to reimburse (either with the proceeds of a Revolving Credit Loan as provided for in this Section 3.5 or with funds from other sources), in same day funds, the Issuing Bank within 5 Business Days of when the Issuing Bank notifies the Borrower of the date and amount of a draft paid under any Letter of Credit for the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by the Issuing Bank in connection with such payment. Unless the Borrower shall notify the Issuing Bank within one Business Day that the Borrower intends to reimburse the Issuing Bank for such drawing from other sources or funds, the Borrower shall be deemed to have timely given a Notice of Borrowing to the Administrative Agent requesting that the Revolving Credit Lenders make a Revolving Credit Loan bearing interest at the Base Rate on such date in the amount of (a) such draft so paid and (b) any amounts referred to in Section 3.3(c) incurred by the Issuing Bank in connection with such payment, and the Revolving Credit Lenders shall make a Revolving Credit Loan bearing interest at the Base Rate in such amount, the proceeds of which shall be applied to reimburse the Issuing Bank for the amount of the related drawing and costs and expenses. Each Revolving Credit Lender acknowledges and agrees that its obligation to fund a Revolving Credit Loan in accordance with this Section 3.5 to reimburse the Issuing Bank for any draft paid under a Letter of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including, without limitation, non-satisfaction of the conditions set forth in Section 2.3(a) or Article V. If the Borrower has elected to pay the amount of such drawing with funds from other sources and shall fail to reimburse the Issuing Bank as provided above, the unreimbursed amount of such drawing shall bear interest at the rate which would be payable on any outstanding Base Rate Loans which were then overdue from the date such amounts become payable (whether at stated maturity, by acceleration or otherwise) until payment in full.

SECTION 3.6 Obligations Absolute. The Borrower’s obligations under this Article III (including, without limitation, the Reimbursement Obligation) shall be absolute and unconditional under any and all circumstances and irrespective of any set off, counterclaim or defense to payment which the Borrower may have or have had against the Issuing Bank or any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees that the Issuing Bank and the L/C Participants shall not be responsible for, and the Borrower’s Reimbursement Obligation under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit

-35-

may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. The Issuing Bank shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions caused by the Issuing Bank’s gross negligence or willful misconduct, as determined by a court of competent jurisdiction by final nonappealable judgment. The Borrower agrees that any action taken or omitted by the Issuing Bank under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct shall be binding on the Borrower and shall not result in any liability of the Issuing Bank or any L/C Participant to the Borrower. The responsibility of the Issuing Bank to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit.

SECTION 3.7 Effect of Letter of Credit Agreement. To the extent that any provision of any Letter of Credit Agreement related to any Letter of Credit is inconsistent with the provisions of this Article III, the provisions of this Article III shall apply.

In connection with each LIBOR Rate Loan, the Borrower, by giving notice at the times described in Section 2.3 or 4.2, as applicable, shall elect an interest period (each, an “Interest Period”) to be applicable to such Loan, which Interest Period shall be a period of one (1), two (2), three (3), or six (6) months or, if agreed by all of the relevant Lenders, nine (9) or twelve (12) months; provided that:

(i) the Interest Period shall commence on the date of advance of or conversion to any LIBOR Rate Loan and, in the case of immediately successive Interest Periods, each successive Interest Period shall commence on the date on which the immediately preceding Interest Period expires;

(ii) if any Interest Period would otherwise expire on a day that is not a Business Day, such Interest Period shall expire on the next succeeding Business Day; provided, that if any Interest Period with respect to a LIBOR Rate Loan would otherwise expire on a day that is not a Business Day but is a day of the month after which no further Business Day occurs in such month, such Interest Period shall expire on the immediately preceding Business Day;

-36-

(iii) any Interest Period with respect to a LIBOR Rate Loan that begins on the last Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) shall end on the last Business Day of the relevant calendar month at the end of such Interest Period; and

(iv) no Interest Period shall extend beyond the Maturity Date and Interest Periods shall be selected by the Borrower so as to permit the Borrower to make without payment of any amounts pursuant to Section 4.9.

(c) Post-Default Rate. Subject to Section 10.3, (i) immediately upon the occurrence and during the continuance of an Event of Default under Section 10.1(h) or (i), or (ii) at the election of the Required Lenders, upon the occurrence and during the continuance of any other Event of Default, (A) the Borrower shall no longer have the option to request LIBOR Rate Loans, Swingline Loans or Letters of Credit, (B) all outstanding LIBOR Rate Loans shall bear interest at a rate per annum of two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to LIBOR Rate Loans until the end of the applicable Interest Period and thereafter at a rate equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Base Rate Loans, and (C) all outstanding Base Rate Loans and other Obligations arising hereunder or under any other Loan Document shall bear interest at a rate per annum equal to two percent (2%) in excess of the rate (including the Applicable Margin) then applicable to Base Rate Loans or such other Obligations arising hereunder or under any other Loan Document. Interest shall continue to accrue on the Obligations after the filing by or against the Borrower of any petition seeking any relief in bankruptcy or under any act or law pertaining to insolvency or debtor relief, whether state, federal or foreign.

(d) Interest Payment and Computation. Interest on each Base Rate Loan shall be due and payable in arrears on the last Business Day of each fiscal quarter commencing December 31, 2010; and interest on each LIBOR Rate Loan shall be due and payable on the last day of each Interest Period applicable thereto, and if such Interest Period extends over three (3) months, at the end of each three (3) month interval during such Interest Period. All computations of interest for Base Rate Loans when the Base Rate is determined by the Prime Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other computations of fees and interest provided hereunder shall be made on the basis of a 360-day year and actual days elapsed (which results in more fees or interest, as applicable, being paid than if computed on the basis of a 365/366-day year).

(e) Maximum Rate. In no contingency or event whatsoever shall the aggregate of all amounts deemed interest under this Agreement charged or collected pursuant to the terms of this Agreement exceed the highest rate permissible under any Applicable Law which a court of competent jurisdiction shall, in a final determination, deem applicable hereto. In the event that such a court determines that the Lenders have charged or received interest hereunder in excess of the highest applicable rate, the rate in effect hereunder shall automatically be reduced to the maximum rate permitted by Applicable Law and the Lenders shall at the Administrative Agent’s option (i) promptly refund to the Borrower any interest received by the Lenders in excess of the maximum lawful rate or (ii) apply such excess to the principal balance of the Obligations on a pro rata basis. It is the intent hereof that the Borrower not pay or contract to pay, and that neither the Administrative Agent nor any Lender receive or contract to receive, directly or indirectly in any manner whatsoever, interest in excess of that which may be paid by the Borrower under Applicable Law.

SECTION 4.2 Notice and Manner of Conversion or Continuation of Loans. Provided that no Default or Event of Default has occurred and is then continuing, the Borrower shall have the option to (a) convert at any time following the third Business Day after the Closing Date all or any portion of any

-37-

outstanding Base Rate Loans (other than Swingline Loans) in a principal amount equal to $5,000,000 or any whole multiple of $1,000,000 in excess thereof into one or more LIBOR Rate Loans and (b) upon the expiration of any Interest Period, (i) convert all or any part of its outstanding LIBOR Rate Loans in a principal amount equal to $3,000,000 or a whole multiple of $1,000,000 in excess thereof into Base Rate Loans (other than Swingline Loans) or (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the Borrower desires to convert or continue Loans as provided above, the Borrower shall give the Administrative Agent irrevocable prior written notice in the form attached as Exhibit E (a “Notice of Conversion/Continuation”) not later than 11:00 a.m. three (3) Business Days before the day on which a proposed conversion or continuation of such Loan is to be effective specifying (A) the Loans to be converted or continued, and, in the case of any LIBOR Rate Loan to be converted or continued, the last day of the Interest Period therefor, (B) the effective date of such conversion or continuation (which shall be a Business Day), (C) the principal amount of such Loans to be converted or continued, and (D) the Interest Period to be applicable to such converted or continued LIBOR Rate Loan. The Administrative Agent shall promptly notify the affected Lenders of such Notice of Conversion/Continuation.

SECTION 4.3 Fees.

(a) Commitment Fee. Commencing on the Closing Date, the Borrower shall pay to the Administrative Agent, for the account of the Revolving Credit Lenders (other than any Defaulting Lender), a non-refundable commitment fee (the “Commitment Fee”) at a rate per annum equal to 0.50% on the average daily unused portion of the Revolving Credit Commitment of the Revolving Credit Lenders (other than the Defaulting Lenders, if any); provided, that the amount of outstanding Swingline Loans shall not be considered usage of the Revolving Credit Commitment for the purpose of calculating the Commitment Fee. The Commitment Fee shall be payable in arrears on the last Business Day of each fiscal quarter during the term of this Agreement commencing December 31, 2010 and ending on the Maturity Date. Such Commitment Fee shall be distributed by the Administrative Agent to the Revolving Credit Lenders (other than any Defaulting Lender) pro rata in accordance with such Revolving Credit Lenders’ respective Revolving Credit Commitment Percentages.

(b) Other Fees. The Borrower shall pay to the Arranger, the Administrative Agent and the Collateral for their own respective accounts fees in the amounts and at the times specified in the Commitment and Engagement Letter. The Borrower shall pay to the Lenders such fees as shall have been separately agreed upon in writing in the amounts and at the times so specified.

SECTION 4.4 Manner of Payment.

(a) Sharing of Payments. Each payment by the Borrower on account of the principal of or interest on the Loans or of any fee, commission or other amounts (including the Reimbursement Obligation) payable to the Lenders under this Agreement (or any of them) shall be made not later than 1:00 p.m. on the date specified for payment under this Agreement to the Administrative Agent at the Administrative Agent’s Office for the account of the Lenders entitled to such payment in Dollars, in immediately available funds and shall be made without any set off, counterclaim or deduction whatsoever. Any payment received after such time but before 2:00 p.m. Charlotte, North Carolina time on such day shall be deemed a payment on such date for the purposes of Section 10.1, but for all other purposes shall be deemed to have been made on the next succeeding Business Day. Any payment received after 2:00 p.m. Charlotte, North Carolina time shall be deemed to have been made on the next succeeding Business Day for all purposes. Upon receipt by the Administrative Agent of each such payment, the Administrative Agent shall distribute to each such Lender at its address for notices set forth herein its pro rata share of such payment in accordance with the amounts then due and payable to such Lenders, (except as specified below) and shall wire advice of the amount of such credit to each Lender. Each payment to the Administrative Agent

-38-

on account of the principal of or interest on the Swingline Loans or of any fee, commission or other amounts payable to the Swingline Lender shall be made in like manner, but for the account of the Swingline Lender. Each payment to the Administrative Agent of the Issuing Bank’s fees or L/C Participants’ commissions shall be made in like manner, but for the account of the Issuing Bank or the L/C Participants, as the case may be. Each payment to the Administrative Agent of Administrative Agent’s fees or expenses shall be made for the account of the Administrative Agent and any amount payable to any Lender under Sections 4.9, 4.10, 4.11 or 12.3 shall be paid to the Administrative Agent for the account of the applicable Lender. Subject to Section 4.1(b)(ii), if any payment under this Agreement shall be specified to be made upon a day which is not a Business Day, it shall be made on the next succeeding day which is a Business Day and such extension of time shall in such case be included in computing any interest if payable along with such payment.

(b) Defaulting Lenders. Notwithstanding Section 4.4(a), if any Defaulting Lender shall have failed to fund all or any portion of any Revolving Credit Loan (each such Revolving Credit Loan, an “Affected Loan”), each payment by the Borrower hereunder shall be applied first to such Affected Loan and the principal amount and interest with respect to such payment shall be distributed (i) to each Revolving Credit Lender that is not a Defaulting Lender (each, a “Non-Defaulting Lender”) pro rata based on the outstanding principal amount of Affected Loans owing to all Non-Defaulting Lenders, until the principal amount of all Affected Loans has been repaid in full and (ii) to the extent of any remaining amount of such payment, to each Revolving Credit Lender as set forth in Section 4.4(a). Each payment made by the Borrower on account of the interest on any Affected Loans shall be distributed to each Non-Defaulting Lender pro rata based on the outstanding principal amount of Affected Loans owing to all Non-Defaulting Lenders.

SECTION 4.5 Evidence of Indebtedness.

(a) Extensions of Credit. The Extensions of Credit made by each Lender shall be evidenced by one or more accounts or records maintained by such Lender and by the Administrative Agent in the ordinary course of business. The accounts or records maintained by the Administrative Agent and each Lender shall be conclusive absent manifest error of the amount of the Extensions of Credit 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 Administrative Agent in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error. Upon the request of any Lender made through the Administrative Agent, the Borrower shall execute and deliver to such Lender (through the Administrative Agent) a Revolving Credit Note and/or Swingline Note, as applicable, which shall evidence such Lender’s Revolving Credit Loans and/or Swingline Loans, as applicable, in addition to such accounts or records. Each Lender may attach schedules to its Notes and endorse thereon the date, amount and maturity of its Loans and payments with respect thereto.

(b) Participations. In addition to the accounts and records referred to in Section 4.5(a), each Revolving Credit Lender and the Administrative Agent shall maintain in accordance with its usual practice accounts or records evidencing the purchases and sales by such Revolving Credit Lender of participations in Letters of Credit and Swingline Loans. In the event of any conflict between the accounts and records maintained by the Administrative Agent and the accounts and records of any Revolving Credit Lender in respect of such matters, the accounts and records of the Administrative Agent shall control in the absence of manifest error.

-39-

SECTION 4.6 Adjustments. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender’s receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations (other than pursuant to Sections 4.9, 4.10, 4.11 or 12.3) greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the Administrative Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and other amounts owing them; provided that

(i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and

(ii) the provisions of this paragraph shall not be construed to apply to (A) any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or (B) any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in Swingline Loans and Letters of Credit to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

Each Credit Party consents to the foregoing and agrees, to the extent it may effectively do so under Applicable Law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Credit Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Credit Party in the amount of such participation.

SECTION 4.7 Obligations of Lenders.

(a) Funding by Lenders; Presumption by Administrative Agent. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any borrowing, or with respect to same day borrowings prior to 11:00 a.m. on the date of such borrowing, that such Lender will not make available to the Administrative Agent such Lender’s share of such borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.3(b) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of a payment to be made by such Lender, the greater of the daily average Federal Funds Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation and (ii) in the case of a payment to be made by the Borrower, the interest rate applicable to Base Rate Loans. If the Borrower and such Lender shall pay such interest to the Administrative Agent for the same or an overlapping period, the Administrative Agent shall promptly remit to the Borrower the amount of such interest paid by the Borrower for such period. If such Lender pays its share of the applicable borrowing to the Administrative Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

-40-

(b) Nature of Obligations of Lenders Regarding Extensions of Credit. The obligations of the Lenders under this Agreement to make the Loans and issue or participate in Letters of Credit are several and are not joint or joint and several. The failure of any Lender to make available its Revolving Credit Commitment Percentage of any Revolving Credit Loan requested by the Borrower shall not relieve it or any other Lender of its obligation, if any, hereunder to make its Revolving Credit Commitment Percentage of such Loan available on the borrowing date, but no Lender shall be responsible for the failure of any other Lender to make its Revolving Credit Commitment Percentage of such Loan available on the borrowing date.

SECTION 4.8 Changed Circumstances.

(a) Circumstances Affecting LIBOR Rate Availability. In connection with any request for a LIBOR Rate Loan or a conversion to or continuation thereof, if for any reason (i) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Loan, (ii) the Administrative Agent shall determine (which determination shall be conclusive and binding absent manifest error) that reasonable and adequate means do not exist for the ascertaining the LIBOR Rate for such Interest Period with respect to a proposed LIBOR Rate Loan or (iii) the Required Lenders shall determine (which determination shall be conclusive and binding absent manifest error) that the LIBOR Rate does not adequately and fairly reflect the cost to such Lenders of making or maintaining such Loans during such Interest Period, then the Administrative Agent shall promptly give notice thereof to the Borrower. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist, the obligation of the Lenders to make LIBOR Rate Loans and the right of the Borrower to convert any Loan to or continue any Loan as a LIBOR Rate Loan shall be suspended, and in the case of LIBOR Rate Loans, the Borrower shall either (A) repay in full (or cause to be repaid in full) the then outstanding principal amount of each such LIBOR Rate Loan together with accrued interest thereon (subject to Section 4.1(d)), on the last day of the then current Interest Period applicable to such LIBOR Rate Loan; or (B) convert the then outstanding principal amount of each such LIBOR Rate Loan to a Base Rate Loan as of the last day of such Interest Period.

(b) Laws Affecting LIBOR Rate Availability. If, after the date hereof, the introduction of, or any change in, any Applicable Law or any change in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any of the Lenders (or any of their respective Lending Offices) with any request or directive (whether or not having the force of law) of any such Governmental Authority, central bank or comparable agency, shall make it unlawful or impossible for any of the Lenders (or any of their respective Lending Offices) to honor its obligations hereunder to make or maintain any LIBOR Rate Loan, such Lender shall promptly give notice thereof to the Administrative Agent and the Administrative Agent shall promptly give notice to the Borrower and the other Lenders. Thereafter, until the Administrative Agent notifies the Borrower that such circumstances no longer exist the obligations of the Lenders to make LIBOR Rate Loans, and the right of the Borrower to convert any Loan or continue any Loan as a LIBOR Rate Loan shall be suspended and thereafter the Borrower may select only Base Rate Loans.

SECTION 4.9 Indemnity. The Borrower hereby indemnifies each of the Lenders against any loss or expense which may arise or be attributable to each Lender’s obtaining, liquidating or employing deposits or other funds acquired to effect, fund or maintain any Loan (a) as a consequence of any failure by the Borrower to make any payment when due of any amount due hereunder in connection with a LIBOR Rate Loan, (b) due to any failure of the Borrower to borrow, continue or convert on a date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation or (c) due to any payment, prepayment or conversion of any LIBOR Rate Loan on a date other than the last day of the Interest Period

-41-

therefor including without limitation due to any assignment required by the Borrower pursuant to Section 4.12(b) hereof. The amount of such loss or expense shall be determined, in the applicable Lender’s sole discretion, based upon the assumption that such Lender funded its Revolving Credit Commitment Percentage of the LIBOR Rate Loans in the London interbank market and using any reasonable attribution or averaging methods which such Lender deems appropriate and practical. A certificate of such Lender setting forth the basis for determining such amount or amounts necessary to compensate such Lender shall be forwarded to the Borrower through the Administrative Agent and shall be conclusively presumed to be correct save for manifest error.

SECTION 4.10 Increased Costs.

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

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or advances, loans or other credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Rate) or the Issuing Bank;

(ii) subject any Lender or the Issuing Bank to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit, any participation in a Letter of Credit or any LIBOR Rate Loan made by it, or change the basis of taxation of payments to such Lender or the Issuing Bank in respect thereof (except for Indemnified Taxes or Other Taxes covered by Section 4.11 and the imposition of, or any change in the rate of any Excluded Tax payable by such Lender or the Issuing Bank); or

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

and the result of any of the foregoing shall be to increase the cost to such Lender of making, converting into or maintaining any LIBOR Rate Loan (or of maintaining its obligation to make any such Loan), or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or any other amount) then, upon written request of such Lender or the Issuing Bank, the Borrower shall promptly pay to any such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law affecting such Lender or the Issuing Bank or any lending office of such Lender or such Lender’s or the Issuing Bank’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Revolving Credit Commitment of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time upon written request of such Lender or such Issuing Bank the Borrower shall

-42-

promptly pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement. A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section 4.10 and delivered to the Borrower shall be conclusive absent manifest error; provided that such amount shall have been determined on a reasonable basis. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d) Delay in Requests. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 4.10 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs incurred or reductions suffered more than six (6) months prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor (except that if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to above shall be extended to include the period of retroactive effect thereof).

SECTION 4.11 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower hereunder or under any other Loan Document shall be made free and clear of and without reduction or withholding for any Indemnified Taxes; provided that if the Borrower shall be required by Applicable Law to deduct any Indemnified Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.11) the Administrative Agent, the applicable Lender or the Issuing Bank, as the case may be, receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall timely pay the full amount deducted to the relevant Governmental Authority in accordance with Applicable Law.

(b) Payment of Other Taxes by the Borrower. Without limiting the provisions of paragraph (a) above, the Borrower shall timely pay any Other Taxes to the relevant Governmental Authority in accordance with Applicable Law.

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, for the full amount of any Indemnified Taxes (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority; provided that the Borrower shall not be obligated to indemnify the Administrative Agent, any Lender or the Issuing Bank for any amount in respect of any such penalties, interest or reasonable expenses if written demand therefor was not made by the Administrative Agent, such Lender or the Issuing Bank within 180 days from the date on which such party makes payment for such penalties, interest or expenses; provided further that the foregoing limitation shall not apply to any such penalties, interest or reasonable expenses arising out of the retroactive application of any such Indemnified Tax. Any payment pursuant to such indemnification shall be made within 30 days after demand therefor. A certificate as to the amount

-43-

of such payment or liability delivered to the Borrower by a Lender or the Issuing Bank (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, shall be conclusive absent manifest error.

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

(e) Status of Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is resident for tax purposes, or any treaty to which such jurisdiction is a party, with respect to payments hereunder or under any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by Applicable Law as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, in the event that the Borrower is a resident for tax purposes in the United States, any Foreign Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable:

(i) duly completed copies of Internal Revenue Service Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party,

(ii) duly completed copies of Internal Revenue Service Form W-8ECI,

(iii) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (x) a certificate to the effect that such Foreign Lender is not (A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

(iv) any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States Federal withholding tax duly completed together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower to determine the withholding or deduction required to be made.

(f) Treatment of Certain Refunds. If the Administrative Agent, a Lender or the Issuing Bank determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section with

-44-

respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the Issuing Bank, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the Borrower, upon the request of the Administrative Agent, such Lender or the Issuing Bank, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent, such Lender or the Issuing Bank in the event the Administrative Agent, such Lender or the Issuing Bank is required to repay such refund to such Governmental Authority. This paragraph shall not be construed to require the Administrative Agent, any Lender or the Issuing Bank to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

(g) Survival. Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section shall survive the payment in full of the Obligations and the termination of the Revolving Credit Commitment.

SECTION 4.12 Mitigation Obligations; Replacement of Lenders.

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 4.10, or requires the Borrower to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.11, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 4.10 or Section 4.11, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 4.10, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.11, or if any Lender is a Defaulting Lender hereunder or becomes a Non-consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent (x) require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.10), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

First, to payment of that portion of the Obligations constituting fees, indemnities, expenses and other amounts, including attorney fees, payable to the Administrative Agent in its capacity as such, the Issuing Bank in its capacity as such and the Swingline Lender in its capacity as such (ratably among the Administrative Agent, the Issuing Bank and Swingline Lender in proportion to the respective amounts described in this clause First payable to them);

Second, to payment of that portion of the Obligations constituting fees, indemnities and other amounts (other than principal and interest) payable to the Lenders under the Loan Documents, including attorney fees (ratably among the Lenders in proportion to the respective amounts described in this clause Second payable to them);

Third, to payment of that portion of the Obligations constituting accrued and unpaid interest on the Loans and Reimbursement Obligations (ratably among the Lenders in proportion to the respective amounts described in this clause Third payable to them);

Fourth, to payment of that portion of the Obligations constituting unpaid principal of the Loans, Reimbursement Obligations and Specified Hedge Obligations (including any termination payments and any accrued and unpaid interest thereon) (ratably among the Lenders and the counterparties to the Specified Hedge Obligations in proportion to the respective amounts described in this clause Fourth held by them);

-87-

Fifth, to the Administrative Agent for the account of the Issuing Bank, to cash collateralize any L/C Obligations then outstanding; and

Last, the balance, if any, after all of the Obligations have been indefeasibly paid in full, to the Borrower or as otherwise required by Applicable Law.

SECTION 10.5 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any Credit Party, the Administrative Agent (irrespective of whether the principal of any Loan or L/C Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, L/C Obligations and all other Obligations arising under the Loan Document that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Sections 3.3, 4.3 and 12.3) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Sections 3.3, 4.3 and 12.3.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

ARTICLE XI

THE ADMINISTRATIVE AGENT

SECTION 11.1 Appointment and Authority. Each of the Lenders and the Issuing Bank hereby irrevocably designates and appoints Wells Fargo to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of this Article XI are solely for the benefit of the Administrative Agent, the Lenders and the Issuing Bank, and neither the Borrower nor any Subsidiary thereof shall have rights as a third party beneficiary of any of such provisions.

-88-

The Administrative Agent shall also act as the Collateral Agent under the Loan Documents, and each of the Lenders (including in its capacity as counterparty to a Specified Hedging Agreement) and the Issuing Bank hereby irrevocably appoints and authorizes the Administrative Agent to act as the agent of such Lender and the Issuing Bank for purposes of acquiring, holding and enforcing any and all Liens on Collateral granted by any of the Credit Party to secure any of the Obligations, together with such powers and discretion as are reasonably incidental thereto. In this connection, the Collateral Agent and any co-agents, sub-agents and attorneys-in-fact appointed by the Administrative Agent pursuant to this Article XI for purposes of holding or enforcing any Lien on the Collateral (or any portion thereof) granted under the Security Documents, or for exercising any rights and remedies thereunder at the direction of the Administrative Agent), shall be entitled to the benefits of all provisions of this Article XI and Article XII (including Section 12.3, as though such co-agents, sub-agents and attorneys-in-fact were the Collateral Agent under the Loan Documents) as if set forth in full herein with respect thereto.

SECTION 11.2 Rights as a Lender. The Person serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as the Administrative Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, act as the financial advisor or in any other advisory capacity for and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if such Person were not the Administrative Agent hereunder and without any duty to account therefor to the Lenders.

SECTION 11.3 Exculpatory Provisions. The Administrative Agent shall not have any duties or obligations except those expressly set forth herein and in the other Loan Documents. Without limiting the generality of the foregoing, the Administrative Agent:

(a) shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;

(b) shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed in writing by the Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan Documents), provided that the Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or Applicable Law; and

(c) shall not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Borrower or any of its Affiliates that is communicated to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.

The Administrative Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Administrative Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.2 and Section 12.2) or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final nonappealable judgment. The Administrative Agent shall be deemed not to have knowledge of any Default unless and

-89-

until notice describing such Default is given to the Administrative Agent by the Borrower, a Lender or the Issuing Bank.

The Administrative Agent shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent.

SECTION 11.4 Reliance by the Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. 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 the Issuing Bank, the Administrative Agent may presume that such condition is satisfactory to such Lender or the Issuing Bank unless the Administrative Agent shall have received notice to the contrary from such Lender or the Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

SECTION 11.5 Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub agents appointed by the Administrative Agent. The Administrative Agent and any such sub agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article XI shall apply to any such sub agent and to the Related Parties of the Administrative Agent and any such sub agent, and shall apply to their respective activities in connection with the syndication of the Facilities as well as activities as Administrative Agent.

SECTION 11.6 Resignation of Administrative Agent.

(a) The Administrative Agent may at any time give notice of its resignation to the Lenders, the Issuing Bank and the Borrower. Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to appoint a successor, which shall be a bank with an office in the United States, or an Affiliate of any such bank with an office in the United States. If no such successor shall have been so appointed by the Required Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent meeting the qualifications set forth above provided that if the Administrative Agent shall notify the Borrower and the Lenders that no qualifying Person has accepted such appointment, then such resignation shall nonetheless become effective in accordance with such notice and (1) the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other

-90-

Loan Documents and (2) all payments, communications and determinations provided to be made by, to or through the Administrative Agent shall instead be made by or to each Lender and the Issuing Bank directly, until such time as the Required Lenders appoint a successor Administrative Agent as provided for above in this paragraph. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring (or retired) Administrative Agent, and the retiring Administrative Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the provisions of this Article XI and Section 12.3 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring Administrative Agent was acting as Administrative Agent.

(b) Any resignation by Wells Fargo as Administrative Agent pursuant to this Section 11.6 shall also constitute its resignation as Issuing Bank and Swingline Lender. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, (a) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank and Swingline Lender, (b) the retiring Issuing Bank and Swingline Lender shall be discharged from all of their respective duties and obligations hereunder or under the other Loan Documents, and (c) the successor Issuing Bank shall issue letters of credit in substitution for the Letters of Credit, if any, outstanding at the time of such succession or make other arrangement satisfactory to the retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank with respect to such Letters of Credit.

SECTION 11.7 Non-Reliance on Administrative Agent and Other Lenders. Each Lender and the Issuing Bank acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender and the Issuing Bank also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

SECTION 11.8 Collateral and Guaranty Matters. The Lenders irrevocably authorize and direct the Administrative Agent (without notice to, or vote or consent of, any counterparty to any Specified Hedging Agreement),

(a) to release any Lien on any Collateral granted to or held by the Administrative Agent, for the ratable benefit of the Secured Parties (whether or not on the date of such release there may be outstanding Specified Hedge Obligations or contingent indemnification obligations not then due), under any Loan Document (i) upon repayment of the outstanding principal of and all accrued interest on the Loans and Reimbursement Obligations, payment of all outstanding fees and expenses hereunder, the termination of the Revolving Credit Commitment and the expiration or termination of all Letters of Credit, (ii) that is disposed or to be disposed of as part of or in connection with any disposition permitted hereunder or under any other Loan Document, or (iii) subject to Section 12.2, if approved, authorized or ratified in writing by the Required Lenders;

-91-

(b) to subordinate or release any Lien on any Collateral (whether or not on the date of such subordination or release there may be outstanding Specified Hedge Obligations or contingent indemnification obligations not then due) granted to or held by the Administrative Agent under any Loan Document to the holder of any Excepted Lien; and

(c) to release any Guarantor (whether or not on the date of such release there may be outstanding Specified Hedge Obligations or contingent indemnification obligations not then due) from its obligations under the Guaranty Agreement, the Security Agreement and any other Loan Documents if such Person ceases to be a Subsidiary as a result of a transaction permitted hereunder.

Upon request by the Administrative Agent at any time, the Required Lenders will confirm in writing the Administrative Agent’s authority to release or subordinate its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty Agreement pursuant to this Section.

SECTION 11.9 Release of Liens and Guarantees of Subsidiaries. If any of the Collateral shall be sold, transferred or otherwise disposed of by the Borrower or any other Credit Party in a transaction permitted by this Agreement (including by way of merger, consolidation or in connection with the sale of a Subsidiary permitted hereunder), then the Administrative Agent, at the request and sole expense of the Borrower or such other Credit Party, shall execute and deliver without recourse, representation or warranty all releases or other documents necessary or desirable for the release of the Liens created by any of the Security Documents on such Collateral. In the case of any such sale, transfer or disposal of any property constituting Collateral in a transaction constituting an Asset Disposition permitted pursuant to Section 9.5, the Liens created by any of the Security Documents on such property shall be automatically released (without need for further action by any person). At the request and sole expense of the Borrower, a Subsidiary that is a Credit Party shall be released from all its obligations under this Agreement and under all other Loan Documents in the event that it shall cease to be a Subsidiary in a transaction permitted by this Agreement (including by way of merger or consolidation), and the Administrative Agent and the Collateral Agent, at the request and sole expense of the Borrower, shall execute and deliver without recourse, representation or warranty all releases or other documents necessary or desirable to evidence or confirm the foregoing.

SECTION 11.10 Specified Hedging Agreements. No Lender or Affiliate thereof party to a Specified Hedging Agreement that obtains the benefits of Section 10.4 or any Collateral by virtue of the provisions hereof or of any Security Document shall have any right to notice of any action or to consent to, direct or object to any action hereunder or under any other Loan Document or otherwise in respect of the Collateral (including the release or impairment of any Collateral) other than in its capacity as a Lender and, in such case, only to the extent expressly provided in the Loan Documents.

Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder, except that

-95-

the Revolving Credit Commitment of such Lender may not be increased or extended without the consent of such Lender.

Notwithstanding anything to the contrary contained in this Section 12.2, if the Administrative Agent and the Borrower shall have jointly identified an obvious error (including, but not limited to, an incorrect cross-reference) or any error or omission of a technical nature, in each case, in any provision of any Loan Document, then the Administrative Agent and/or the Collateral Agent (acting in their sole discretion) and the Borrower or any other relevant Credit Party shall be permitted to amend such provision or cure any ambiguity, defect or inconsistency and such amendment shall become effective without any further action or consent of any other party to any Loan Document.

Notwithstanding anything to the contrary, without the consent of any other Person, the applicable Credit Party or Parties and the Administrative Agent may (in its or their respective sole discretion, or shall, to the extent required by any Loan Document) enter into any amendment or waiver of any Loan Document, or enter into any new agreement or instrument, to effect the granting, perfection, protection, expansion or enhancement of any security interest in Collateral or additional property to become Collateral for the benefit of the Secured Parties, or as required by local law to give effect to, or protect any security interest for the benefit of the Secured Parties, in any property or so that the security interests therein comply with Applicable Law.

The Borrower shall indemnify the Arranger, the Administrative Agent (and any sub-agent thereof), each Lender and the Issuing Bank, and each Related Party of any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee harmless from, and shall pay or reimburse any such Indemnitee for, any and all losses, claims (including, without limitation, any Environmental Claims or civil penalties or fines assessed by OFAC), damages, liabilities and related expenses (including the fees, charges and disbursements of any counsel for any Indemnitee), and shall indemnify and hold harmless, each Indemnitee from, and shall pay or reimburse any such Indemnitee for, incurred by any Indemnitee or asserted against any Indemnitee by any third party or by the Borrower or any other Credit Party arising out of, in connection with, or as a result of (i) the execution or delivery of this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the performance by the parties hereto of their respective obligations hereunder or thereunder or the consummation of the transactions contemplated hereby or thereby, (ii) any

To the fullest extent permitted by Applicable Law, the Borrower and each other Credit Party shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee referred to in clause (b) above shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

If an Event of Default shall have occurred and be continuing, each Lender, the Issuing Bank, the Swingline Lender and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by Applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the Issuing Bank, the Swingline Lender or any such Affiliate to or for the credit or the account of the Borrower or any other Credit Party against any and all of the obligations of the Borrower or such Credit Party now or hereafter existing under this Agreement or any other Loan Document to such Lender, the Issuing Bank or the Swingline Lender, irrespective of whether or not such Lender, the Issuing Bank or the Swingline Lender shall have made any demand under this Agreement or any other Loan Document. The rights of each Lender, the Issuing Bank, the Swingline Lender and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that such Lender, the Issuing Bank, the Swingline Lender or their respective Affiliates may have. Each Lender, the Issuing Bank and the Swingline Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

SECTION 12.5 Governing Law; Jurisdiction, Etc.

(a) Governing Law. This Agreement and the other Loan Documents, unless expressly set forth therein, shall be governed by, construed and enforced in accordance with, the law of the State of New York, without reference to the conflicts or choice of law principles thereof.

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

(c) Waiver of Venue. The Borrower and each other Credit Party irrevocably and unconditionally waives, to the fullest extent permitted by Applicable Law, any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section 12.5. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by Applicable Law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.

(d) Service of Process. Each party hereto irrevocably consents to service of process in the manner provided for notices in Section 12.1. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by Applicable Law.

-98-

SECTION 12.6 Waiver of Jury Trial.

(a) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 12.6.

SECTION 12.7 Reversal of Payments. To the extent any Credit Party makes a payment or payments to the Administrative Agent for the ratable benefit of the Lenders or the Administrative Agent receives any payment or proceeds of the Collateral which payments or proceeds or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to a trustee, receiver or any other party under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or proceeds repaid, the Obligations or part thereof intended to be satisfied shall be revived and continued in full force and effect as if such payment or proceeds had not been received by the Administrative Agent.

SECTION 12.8 Injunctive Relief; Punitive Damages.

(a) The Borrower recognizes that, in the event the Borrower fails to perform, observe or discharge any of its obligations or liabilities under this Agreement, any remedy of law may prove to be inadequate relief to the Lenders. Therefore, the Borrower agrees that the Lenders, at the Lenders’ option, shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving actual damages.

(b) The Administrative Agent, the Lenders and the Borrower (on behalf of itself and the other Credit Parties) hereby agree that no such Person shall have a remedy of punitive or exemplary damages against any other party to a Loan Document and each such Person hereby waives any right or claim to punitive or exemplary damages that they may now have or may arise in the future in connection with any Dispute, whether such Dispute is resolved through arbitration or judicially.

SECTION 12.9 Accounting Matters. If at any time any change in GAAP would affect the computation of any financial ratio or requirement set forth in any Loan Document, and either the Borrower or the Required Lenders shall so request, the Administrative Agent, the Lenders and the Borrower shall negotiate in good faith to amend such ratio or requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Required Lenders); provided that, until so amended, (i) such ratio or requirement shall continue to be computed in accordance with GAAP prior to such change therein and (ii) the Borrower shall provide to the Administrative Agent and the Lenders Financial Statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation between calculations of such ratio or requirement made before and after giving effect to such change in GAAP.

SECTION 12.10 Successors and Assigns; Participations.

(a) Successors and Assigns Generally. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby, except that neither the Borrower nor any other Credit Party may assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of the Administrative Agent and each Lender and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section 12.10, (ii) by way of participation in accordance with the provisions of paragraph (d) of this Section 12.10 or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section 12.10 (and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent provided in paragraph (d) of this Section 12.10 and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Revolving Credit Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(A) in the case of an assignment of the entire remaining amount of the assigning Lender’s Revolving Credit Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(B) in any case not described in paragraph (b)(i)(A) of this Section 12.10, the aggregate amount of the Revolving Credit Commitment (which for this purpose includes Loans outstanding thereunder) or, if the applicable Revolving Credit Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed); provided that the Borrower shall be deemed to have given its consent five (5) Business Days after the date written notice thereof has been delivered by the assigning Lender (through the Administrative Agent) unless such consent is expressly refused by the Borrower prior to such fifth (5th) Business Day;

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Revolving Credit Commitment assigned;

-100-

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(B) of this Section 12.10 and, in addition:

(A) the consent of the Borrower (such consent not to be unreasonably withheld) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided, that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within 5 Business Days after having received notice thereof;

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments in respect of the Revolver Facility if such assignment is to a Person that is not a Lender with a Revolving Credit Commitment, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

(C) the consents of the Issuing Bank and the Swingline Lender (such consents not to be unreasonably withheld or delayed) shall be required for any assignment that increases the obligation of the assignee to participate in exposure under one or more Letters of Credit (whether or not then outstanding) or for any assignment in respect of the Revolver Facility.

(iv) Assignment and Assumption. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 for each assignment (provided, that only one such fee will be payable in connection with simultaneous assignments to two or more Approved Funds by a Lender), and the assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

(v) No Assignment to Certain Persons. No such assignment shall be made to the Borrower or any of the Borrower’s Affiliates or Subsidiaries.

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section 12.10, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 4.8, 4.9, 4.10, 4.11 and 12.3 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section 12.10.

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Charlotte, North Carolina, a copy of each Assignment and

-101-

Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Revolving Credit Commitment of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). Upon its receipt of an Assignment and Assumption in compliance with the requirements of this Section together with any other documents or certificates required to be delivered hereunder or reasonably requested by the Administrative Agent, and including any fees payable with respect to such assignment, the Administrative Agent shall accept such Assignment and Assumption and record it in the Register. The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender (but only to the extent of entries in the Register that are applicable to such Lender), at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Revolving Credit Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower, the Administrative Agent, Issuing Bank, Swingline Lender and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement.

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver or modification described in Section 12.2 that directly affects such Participant and could not be affected by a vote of the Required Lenders. Subject to paragraph (e) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.8, 4.9, 4.10 and 4.11 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section 12.10 . To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.4 as though it were a Lender, provided such Participant agrees to be subject to Section 4.6 as though it were a Lender.

(e) Limitations upon Participant Rights. A Participant shall not be entitled to receive any greater payment under Sections 4.10 and 4.11 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. No Participant shall be entitled to the benefits of Section 4.11 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 4.11(e) as though it were a Lender.

(f) Certain Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

-102-

SECTION 12.11 Confidentiality. Each of the Administrative Agent, the Lenders and the Issuing Bank agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its and its Affiliates’ respective partners, directors, officers, employees, agents, advisors and other representatives (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by, or required to be disclosed to, any rating agency, credit insurance provider or regulatory or similar authority purporting to have jurisdiction over it (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by Applicable Laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies under this Agreement or under any other Loan Document (or any Specified Hedging Agreement) or any action or proceeding relating to this Agreement or any other Loan Document (or any Hedging Agreement with a Lender or the Administrative Agent) or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, Participant or proposed Participant or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower and its obligations, (g) with the consent of the Borrower, (h) to Gold Sheets and other similar bank trade publications, such information to consist of deal terms and other information customarily found in such publications, or (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section 12.11 or (y) becomes available to the Administrative Agent, any Lender, the Issuing Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower or (j) to governmental regulatory authorities in connection with any regulatory examination of the Administrative Agent or any Lender or in accordance with the Administrative Agent’s or any Lender’s regulatory compliance policy if the Administrative Agent or such Lender deems necessary for the mitigation of claims by those authorities against the Administrative Agent or such Lender or any of its subsidiaries or affiliates. For purposes of this Section 12.11, “Information” means all information received from any Credit Party or any Subsidiary thereof relating to any Credit Party or any Subsidiary thereof or any of their respective businesses, other than any such information that is available to the Administrative Agent, any Lender or the Issuing Bank on a nonconfidential basis prior to disclosure by any Credit Party or any Subsidiary thereof; provided that, in the case of information received from a Credit Party or any Subsidiary thereof after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

SECTION 12.12 Performance of Duties. Each of the Credit Party’s obligations under this Agreement and each of the other Loan Documents shall be performed by such Credit Party at its sole cost and expense.

SECTION 12.13 All Powers Coupled with Interest. All powers of attorney and other authorizations granted to the Lenders, the Administrative Agent and any Persons designated by the Administrative Agent or any Lender pursuant to any provisions of this Agreement or any of the other Loan Documents shall be deemed coupled with an interest and shall be irrevocable so long as any of the Obligations remain unpaid or unsatisfied, any of the Commitments remain in effect or the Credit Facility has not been terminated.

-103-

SECTION 12.14 Survival.

(a) All representations and warranties set forth in Article VI and all representations and warranties contained in any certificate, or any of the Loan Documents (including, but not limited to, any such representation or warranty made in or in connection with any amendment thereto) shall constitute representations and warranties made under this Agreement. All representations and warranties made under this Agreement shall be made or deemed to be made at and as of the Closing Date (except those that are expressly made as of a specific date), shall survive the Closing Date and shall not be waived by the execution and delivery of this Agreement, any investigation made by or on behalf of the Lenders or any borrowing hereunder.

(b) Notwithstanding any termination of this Agreement, the indemnities to which the Administrative Agent and the Lenders are entitled under the provisions of this Article XII and any other provision of this Agreement and the other Loan Documents shall continue in full force and effect and shall protect the Administrative Agent and the Lenders against events arising after such termination as well as before.

SECTION 12.15 Titles and Captions. Titles and captions of Articles, Sections and subsections in, and the table of contents of, this Agreement are for convenience only, and neither limit nor amplify the provisions of this Agreement.

SECTION 12.16 Severability of Provisions. Any provision of this Agreement or any other Loan Document which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective only to the extent of such prohibition or unenforceability without invalidating the remainder of such provision or the remaining provisions hereof or thereof or affecting the validity or enforceability of such provision in any other jurisdiction.

SECTION 12.17 Counterparts; Integration; Effectiveness; Electronic Execution.

(a) Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed signature page of this Agreement or Lender Authorization by facsimile transmission shall be effective as delivery of a manually executed counterparty hereof. This Agreement and the other Loan Documents, and any separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. In the event of any conflict between the provisions of this Agreement and those of any other Loan Document, the provisions of this Agreement shall control; provided that the inclusion of supplemental rights or remedies in favor of the Administrative Agent or the Lenders in any other Loan Document shall not be deemed a conflict with this Agreement. Each Loan Document was drafted with the joint participation of the respective parties thereto and shall be construed neither against nor in favor of any party, but rather in accordance with the fair meaning thereof. Except as provided in Section 5.1, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto.

(b) The Borrower expressly acknowledges and agrees that each covenant contained in Articles VII, VIII, IX or X hereof shall be given independent effect. Accordingly, the Borrower shall not engage in any transaction or other act otherwise permitted under any covenant contained in Articles VII,

-104-

VIII, IX or X, before or after giving effect to such transaction or act, the Borrower shall or would be in breach of any other covenant contained in Articles VII, VIII, IX or X.

(c) Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

SECTION 12.18 Term of Agreement. This Agreement shall remain in effect from the Closing Date through and including the date upon which all Obligations (other than (a) contingent indemnification obligations not then due and (b) the Specified Hedge Obligations) arising hereunder or under any other Loan Document shall have been indefeasibly and irrevocably paid and satisfied in full and the Revolving Credit Commitment has been terminated. No termination of this Agreement shall affect the rights and obligations of the parties hereto arising prior to such termination or in respect of any provision of this Agreement which survives such termination.

SECTION 12.19 USA Patriot Act. The Administrative Agent and each Lender hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies the Borrower and Guarantors, which information includes the name and address of each Borrower and Guarantor and other information that will allow such Lender to identify such Borrower or Guarantor in accordance with the Act.

SECTION 12.20 Delivery of Lender Authorization. Each initial Lender (other than any Lender whose name appears on the signature pages to this Agreement) shall become a party to this Agreement by delivering to the Administrative Agent a Lender Authorization duly executed by such Lender.
