ARTICLE II

THE LOANS AND LETTERS OF CREDIT

Section 2.1 Commitments to Lend; Notes.

(a) Subject to the terms and conditions hereof, each Revolving Lender agrees, severally and not jointly, to make Revolving Loans to Borrower upon the request of Borrower from time to time during the Commitment Period; provided that (a) subject to Sections 3.3, 3.4 and 3.6, Revolving Loans of the same Type made on the same day shall be made by Revolving Lenders in accordance with their respective Percentage Shares and as part of the same Borrowing; and (b) after giving effect to such Revolving Loans, the Revolving Facility Usage shall not exceed the Aggregate Revolving Loan Commitment then in effect. The amount of all Revolving Loans in any Borrowing must be greater than or equal to $100,000, or must equal the remaining availability under the Aggregate Revolving Loan Commitment. The obligation of Borrower to repay to each Revolving Lender the aggregate amount of all Revolving Loans made by such Revolving Lender, together with interest accruing in connection therewith, may, at the request of such Revolving Lender, be evidenced by a promissory note made by Borrower payable to the order of such Revolving Lender in the principal amount of the Revolving Loan Commitment of the applicable Revolving Lender, substantially in the form of Exhibit 2.1(a) (each a “Revolving Note” and, collectively, the “Revolving Notes”). The amount of principal owing on any Revolving Note at any given time shall be the aggregate amount of all Revolving Loans theretofore made by such Revolving Lender minus all payments of principal theretofore received by such Revolving Lender on such Revolving Note. Interest on each Revolving Loan

29

shall accrue and be due and payable as provided herein. Each Revolving Loan shall be due and payable as provided herein, and shall be due and payable in full on the Maturity Date. Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow Revolving Loans hereunder.

(b) Subject to the terms and conditions hereof, each Term Lender agrees, severally and not jointly, to make a single Term Loan to Borrower on the Amendment No. 6 Effective Date in a principal amount equal to such Lender’s Term Loan Commitment. The obligation of Borrower to repay to each Term Lender the aggregate amount of the Term Loan made by such Term Lender, together with interest accruing in connection therewith, may, at the request of such Term Lender, be evidenced by a promissory note made by Borrower payable to the order of such Term Lender in the principal amount of the Term Loan Commitment of the applicable Term Lender, substantially in the form of Exhibit 2.1(b) (each a “Term Note” and, collectively, the “Term Notes”). The amount of principal owing on any Term Note at any given time shall be the amount of the Term Loan made by such Term Lender minus all payments of principal theretofore received by such Term Lender on such Term Note. Interest on each Term Loan shall accrue and be due and payable as provided herein. Each Term Loan shall be due and payable as provided herein, and shall be due and payable in full on the Maturity Date. Amounts repaid or prepaid in respect of the Term Loans may not be reborrowed.

Section 2.2 Requests for Loans. Borrower must give to Agent written or electronic notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing of new Loans to be advanced by the applicable Lenders. Each such notice constitutes a “Borrowing Notice” hereunder and must:

(a) specify (i) the aggregate amount of any such Borrowing of new Base Rate Loans and the date on which such Base Rate Loans are to be advanced, or (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced (which shall be the first day of the Interest Period which is to apply thereto), and the length of the applicable Interest Period; and

(b) be received by Agent not later than 11:00 a.m., Houston, Texas time, on (i) the day on which any such Base Rate Loans are to be made, or (ii) the third Business Day preceding the day on which any such Eurodollar Loans are to be made.

Each such written request or confirmation must be made in the form and substance of the “Borrowing Notice” attached hereto as Exhibit 2.2(b), duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Borrowing Notice, Agent shall give each applicable Lender prompt notice of the terms thereof. If all conditions precedent to such new Loans have been met, each applicable Lender will on the date requested promptly remit to Agent at Agent’s office in Houston, Texas the amount of such Lender’s new Loan in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Loans have been neither met nor waived as provided herein, Agent shall promptly make such Loans available to Borrower. Unless Agent shall have received prompt notice from a Lender that such Lender will not make available to Agent such Lender’s new Loan, Agent may in its discretion assume that

30

such Lender has made such Loan available to Agent in accordance with this Section and Agent may if it chooses, in reliance upon such assumption, make such Loan available to Borrower. If and to the extent such Lender shall not so make its new Loan available to Agent, such Lender and Borrower severally agree to pay or repay to Agent within three days after demand the amount of such Loan together with interest thereon, for each day from the date such amount was made available to Borrower until the date such amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate, if such Lender is making such payment and (ii) the interest rate applicable at the time to the other new Loans made on such date, if Borrower is making such repayment. If neither such Lender nor Borrower pays or repays to Agent such amount within such three-day period, Agent shall in addition to such amount be entitled to recover from such Lender and from Borrower, on demand, interest thereon at the Default Rate, calculated from the date such amount was made available to Borrower. The failure of any Lender to make any new Loan to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its new Loan, but no Lender shall be responsible for the failure of any other Lender to make any new Loan to be made by such other Lender.

Section 2.3 Continuations and Conversions of Existing Loans. Borrower may make the following elections with respect to Loans already outstanding: to convert Base Rate Loans to Eurodollar Loans, to convert Eurodollar Loans to Base Rate Loans on the last day of the Interest Period applicable thereto, and to continue Eurodollar Loans beyond the expiration of such Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Loans of the same Class made pursuant to separate Borrowings into one new Borrowing or divide existing Loans made pursuant to one Borrowing into separate new Borrowings; provided that Borrower may have no more than five Borrowings of Eurodollar Loans outstanding at any time. To make any such election, Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any such Conversion or Continuation of existing Loans, with a separate notice given for each new Borrowing. Each such notice constitutes a “Continuation/Conversion Notice” hereunder and must:

(a) specify the existing Loans which are to be Continued or Converted;

(b) specify (i) the aggregate amount of any Borrowing of Base Rate Loans into which such existing Loans are to be converted and the date on which such Continuation or Conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Loans are to be continued or converted, the date on which such Continuation or Conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and

(c) be received by Agent not later than 11:00 a.m., Houston, Texas time, on (i) the day on which any such conversion to Base Rate Loans is to occur, or (ii) the third Business Day preceding the day on which any such Continuation or Conversion to Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and substance of the “Continuation/Conversion Notice” attached hereto as Exhibit 2.3(c), duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement

31

by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Continuation/Conversion Notice, Agent shall give each applicable Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and binding on Borrower. During the continuance of any Default, Borrower may not make any election to convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any Continuation/Conversion Notice with respect to a Borrowing of existing Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans shall automatically be converted into Base Rate Loans at the end of such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any Continuation or Conversion of existing Loans pursuant to this Section, and no such Continuation or Conversion shall be deemed to be a new advance of funds for any purpose; such Continuations and Conversions merely constitute a change in the interest rate applicable to already outstanding Loans.

Section 2.4 Use of Proceeds. Borrower shall use the Loans to provide working capital for its operations and for other general corporate purposes. Borrower shall use all Letters of Credit for its general corporate purposes. In no event shall the funds from any Loan or any Letter of Credit be used directly or indirectly by any Person for personal, family, household or agricultural purposes or for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any Margin Stock (except in connection with an acquisition or Investment permitted under Section 7.7 which does not violate Regulation U of the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such Margin Stock. Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower’s important activities, in the business of extending credit to others for the purpose of purchasing or carrying such Margin Stock. No Loan or Letter of Credit will be requested and no proceeds of any Loan or Letter of Credit will be used (i) in furtherance of an offer, payment, promise to pay, or authorization of the payment or giving of money, or anything else of value, to any Person in violation of any Anti-Corruption Laws, (ii) to fund any activities or business (A) of or with any Person, that, at the time of such funding, is the subject of Sanctions or (B) in any country or territory that, at the time of such funding, is, or whose government is, the subject of Sanctions, or (iii) in any manner that would result in the violation of any Sanctions applicable to any party hereto.

(c) Commitment Fees. In consideration of each Revolving Loan Commitment of each Revolving Lender to make Revolving Loans, Borrower will pay to Agent for the account of each Revolving Lender a fee (the “Commitment Fee”) determined on a daily basis by multiplying the applicable Commitment Fee Rate by the Percentage Share of such Revolving Lender of the unused portion of the aggregate Revolving Loan Commitments on each day during the Commitment Period, determined for each such day by deducting from the amount of the aggregate Revolving Loan Commitments at the end of such day the Revolving Facility Usage at the end of such day (calculated as if no Swingline Loans were outstanding). This Commitment Fee shall be due and payable in arrears on the first day of each Fiscal Quarter and at the end of the Commitment Period.

(d) Additional Fees. In addition to all other amounts due to Agent under the Loan Documents, Borrower will pay fees to the Lead Arranger as described in a letter dated November 19, 2019, among Lead Arranger, Wells Fargo Bank, National Association and Borrower.

Borrower may, without penalty, (i) upon notice to Agent to be received no later than 11:00 a.m., Houston, Texas time, with respect to any Base Rate Loan and (ii) upon three Business Days’ notice to each Lender with respect to any Eurodollar Loan, from time to time and without premium or penalty prepay the Loans, in whole or in part, provided (A) that the aggregate amounts of all partial prepayments of principal on the Notes equals $100,000 or any higher integral multiple of $100,000; and (B) that if Borrower prepays any Eurodollar Loan on any day other than the last day of the Interest Period applicable thereto, it shall pay to Lenders any amounts due under Section 3.5.

(b) Mandatory Prepayments.

(i) If at any time the Revolving Facility Usage exceeds the Aggregate Revolving Loan Commitment (whether due to a reduction in the Revolving Loan Commitments in accordance with this Agreement, or otherwise), Borrower shall immediately upon demand prepay the principal of the Revolving Loans (and after the Revolving Loans are repaid in full, provide LC Collateral in accordance with Section 2.14(a)) in an amount at least equal to such excess.

(ii) If Borrower or any other Restricted Person receives Net Cash Proceeds from any Asset Disposition and the aggregate amount of such Net Cash Proceeds exceeds $30,000,000 in any Fiscal Year, then, within ten Business Days of receipt thereof, Borrower shall apply such Net Cash Proceeds to prepay the Term Loans; provided that, so long as no Event of Default exists, Borrower shall be permitted to reinvest such Net Cash Proceeds in productive assets or properties or otherwise in the business of Borrower and its Subsidiaries within 365 days after receipt thereof, in which case, Borrower shall give Agent written notice thereof within ten Business Days of the receipt of such Net Cash Proceeds. If Borrower elects to use Net Cash Proceeds for reinvestment as set forth in the immediately preceding sentence, within 365 days of the date of written notice to Agent of such election, Borrower shall provide evidence reasonably satisfactory to Agent that such reinvestment has been completed on or before such 365-day period and, to the extent such reinvestment has not been completed, Borrower shall prepay the Term Loans in an amount equal to the amount of such Net Cash Proceeds not used for such reinvestment.

(iii) If Borrower or any other Restricted Person issues or incurs any Indebtedness (other than Indebtedness permitted by Section 7.1), Borrower shall promptly (but in any event within three Business Days of receipt thereof) apply the Net Cash Proceeds thereof to prepay the Term Loans.

(c) Prepayments Generally. Each prepayment of principal under this Section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this Section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. All prepayments of Term Loans shall be applied to prepay the Term Loans on a pro rata basis to

34

reduce the subsequent scheduled repayments of the Term Loans to be made pursuant to Section 2.6(b) in the order of maturity of such scheduled payments.

Section 2.8 Termination of Commitments; Reduction of Revolving Loan Commitments.

(a) Unless previously terminated, the Revolving Loan Commitments will terminate on the Maturity Date. The Term Loan Commitments will terminate upon the funding of the Term Loans on the Amendment No. 6 Effective Date.

(b) Borrower may at any time terminate, or from time to time reduce, without premium or penalty, the Revolving Loan Commitments, but (i) each reduction of the Revolving Loan Commitments must be in an amount that is an integral multiple of $100,000 (unless such reduction would reduce the unused Revolving Loan Commitments to zero) and (ii) Borrower shall not terminate or reduce the Revolving Loan Commitments if, after giving effect to any concurrent prepayment of the Revolving Loans in accordance with Section 2.7, the sum of the aggregate Revolving Facility Usage would exceed the Aggregate Revolving Loan Commitment then in effect.

(c) Borrower shall notify Agent of any election to terminate or reduce the Revolving Loan Commitments under Section 2.8(b) at least three Business Days prior to the effective date of that termination or reduction, specifying that election and the effective date thereof. Promptly following receipt of any notice, Agent shall advise the Revolving Lenders of the contents thereof. Each notice delivered by Borrower pursuant to this Section will be irrevocable, except that a notice of termination of the Revolving Loan Commitments delivered by Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by Borrower (by notice to Agent on or prior to the specified effective date) if such condition is not satisfied. Except as provided in the immediately preceding sentence, any termination or reduction of the Revolving Loan Commitments will be permanent and such Revolving Loan Commitments will not be reinstated except pursuant to, and in accordance with, Section 2.17. Except as provided in Section 2.18, each reduction of the Revolving Loan Commitments must be made ratably among the Revolving Lenders in accordance with their respective Revolving Loan Commitments.

Section 2.9 Letters of Credit. Subject to the terms and conditions hereof, Borrower may during the Commitment Period request LC Issuer to, and LC Issuer shall, issue one or more Letters of Credit; provided that, after taking such Letter of Credit into account:

(a) the Revolving Facility Usage does not exceed the Aggregate Revolving Loan Commitment (whether due to a reduction in the Revolving Loan Commitments in accordance with this Agreement, or otherwise) at such time;

(b) the aggregate LC Obligations at such time do not exceed $160,000,000; and

(c) the expiration date of such Letter of Credit is prior to the end of the Commitment Period.

35

All Existing Letters of Credit shall be deemed to have been issued pursuant hereto, and from and after the Closing Date, shall be subject to and governed by the terms and conditions hereof.

Section 2.10 Requesting Letters of Credit. Borrower must make written application for any Letter of Credit at least two (2) Business Days (or such shorter period as LC Issuer may in its discretion from time to time agree) before the date on which Borrower desires for LC Issuer to issue such Letter of Credit. By making any such written application, Borrower shall be deemed to have represented and warranted that the LC Conditions described in Section 2.11 will be met as of the date of issuance of such Letter of Credit. Each such written application for a Letter of Credit must be made in writing in the form and substance of Exhibit 2.10, the terms and provisions of which are hereby incorporated herein by reference (or in such other form as may mutually be agreed upon by LC Issuer and Borrower). Two (2) Business Days after the LC Conditions for a Letter of Credit have been met (or if LC Issuer otherwise desires to issue such Letter of Credit), LC Issuer will issue such Letter of Credit at LC Issuer’s office in Houston, Texas. If any provisions of any LC Application conflict with any provisions of this Agreement, the provisions of this Agreement shall govern and control. Borrower shall promptly examine a copy of each Letter of Credit and each amendment thereto that is delivered to it and, in the event of any claim of noncompliance with Borrower’s instructions or other irregularity, Borrower will promptly notify LC Issuer.

Section 2.11 Reimbursement and Participations.

(a) Reimbursement by Borrower. Each Matured LC Obligation shall constitute a Revolving Loan by LC Issuer to Borrower if not paid by Borrower in accordance with the following sentence. Borrower promises to pay to LC Issuer, or to LC Issuer’s order, on the Business Day immediately following the day on which a demand is made, the full amount of each Matured LC Obligation, together with interest thereon at the Default Rate applicable to Base Rate Loans. The obligation of Borrower to reimburse LC Issuer for each Matured LC Obligation shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement (including any LC Application) under all circumstances, including the following: (i) any lack of validity or enforceability of such Letter of Credit or any other agreement or instrument relating thereto; (ii) the existence of any claim, counterclaim, set-off, defense or other right that Borrower may have at any time against any beneficiary or any transferee of such Letter of Credit (or any Person for whom any such beneficiary or any such transferee may be acting), LC Issuer or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by such Letter of Credit or any agreement or instrument relating thereto, or any unrelated transaction; (iii) any draft, demand, certificate or other document presented under such Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or any loss or delay in the transmission or otherwise of any document required in order to make a drawing under such Letter of Credit; (iv) any payment by LC Issuer under such Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of such Letter of Credit; or (v) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. Without limiting the generality of the foregoing, it is expressly agreed that the absolute and unconditional nature of Borrower’s obligations under this Section to reimburse LC Issuer for each drawing under a Letter of Credit will not be excused by the gross negligence or willful misconduct of LC Issuer. However, the

36

foregoing shall not be construed to excuse LC Issuer from liability to Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by Borrower to the extent permitted by applicable Law) suffered by Borrower that are caused by LC Issuer’s gross negligence or willful misconduct in determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof.

(b) Letter of Credit Advances. If the beneficiary of any Letter of Credit makes a draft or other demand for payment thereunder then Borrower may, during the interval between the making thereof and the honoring thereof by LC Issuer, request Revolving Lenders to make Revolving Loans to Borrower in the amount of such draft or demand, which such Loans shall be made concurrently with LC Issuer’s payment of such draft or demand and shall be immediately used by LC Issuer to repay the amount of the resulting Matured LC Obligation. Such a request by Borrower shall be made in compliance with all of the provisions hereof; provided that for the purposes of the first sentence of Section 2.1(a), the amount of such Loans shall be considered, but the amount of the Matured LC Obligation to be concurrently paid by such Loans shall not be considered.

(c) Participation by Lenders. LC Issuer irrevocably agrees to grant and hereby grants to each Revolving Lender, and to induce LC Issuer to issue Letters of Credit hereunder each Revolving Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from LC Issuer, on the terms and conditions hereinafter stated and for such Lender’s own account and risk, an undivided interest equal to such Lender’s Percentage Share of LC Issuer’s obligations and rights under each Letter of Credit issued hereunder and the amount of each Matured LC Obligation paid by LC Issuer thereunder. Each Revolving Lender unconditionally and irrevocably agrees with LC Issuer that, if a Matured LC Obligation is paid under any Letter of Credit for which LC Issuer is not reimbursed in full by Borrower in accordance with the terms of this Agreement and the related LC Application (including any reimbursement by means of concurrent Loans or by the application of LC Collateral), such Lender shall (in all circumstances and without set-off or counterclaim) pay to LC Issuer on demand, in immediately available funds at LC Issuer’s address for notices hereunder, such Lender’s Percentage Share of such Matured LC Obligation (or any portion thereof which has not been reimbursed by Borrower). Each Revolving Lender’s obligation to pay LC Issuer pursuant to the terms of this subsection is irrevocable and unconditional. If any amount required to be paid by any Revolving Lender to LC Issuer pursuant to this subsection is paid by such Lender to LC Issuer within three Business Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to recover from such Lender, on demand, interest thereon calculated from such due date at the Federal Funds Rate. If any amount required to be paid by any Revolving Lender to LC Issuer pursuant to this subsection is not paid by such Lender to LC Issuer within three Business Days after the date such payment is due, LC Issuer shall in addition to such amount be entitled to recover from such Lender, on demand, interest thereon calculated from such due date at the Default Rate.

(d) Distributions to Participants. Whenever LC Issuer has in accordance with this Section received from any Revolving Lender payment of such Lender’s Percentage Share of any Matured LC Obligation, if LC Issuer thereafter receives any payment of such Matured LC Obligation or any payment of interest thereon (whether directly from Borrower or by application of LC Collateral or otherwise, and excluding only interest for any period prior to LC Issuer’s

37

demand that such Lender make such payment of its Percentage Share), LC Issuer will distribute to such Lender its Percentage Share of the amounts so received by LC Issuer; provided, however, that if any such payment received by LC Issuer must thereafter be returned by LC Issuer, such Lender shall return to LC Issuer the portion thereof which LC Issuer has previously distributed to it.

(e) Calculations. A written advice setting forth in reasonable detail the amounts owing under this Section, submitted by LC Issuer to Borrower or any Lender from time to time, shall be conclusive, absent manifest error, as to the amounts thereof.

Section 2.12 Letter of Credit Fees. In consideration of LC Issuer’s issuance of any Letters of Credit, Borrower agrees to pay (a) to Agent, for the account of all Revolving Lenders in accordance with their respective Percentage Shares, (i) with respect to each Letter of Credit supporting non-financial contractual obligations, a per annum letter of credit fee on the undrawn face amount of such Letter of Credit at a rate equal to 50% of the rate specified as the LC Rate on the Pricing Schedule and (ii) with respect to each other Letter of Credit, a per annum letter of credit fee on the undrawn face amount of such Letter of Credit at a rate equal to the rate specified as the LC Rate on the Pricing Schedule and (b) to such LC Issuer for its own account, a letter of credit fronting fee at a rate equal to 0.125% per annum. The letter of credit fee and the letter of credit fronting fee will be calculated on the undrawn face amount of each Letter of Credit outstanding on each day at the above-applicable rates and will be due and payable in arrears on the first day of each Fiscal Quarter and at the end of the Commitment Period.

Section 2.13 No Duty to Inquire.

(a) Drafts and Demands. LC Issuer is authorized and instructed to accept and pay drafts and demands for payment under any Letter of Credit without requiring, and without responsibility for, any determination as to the existence of any event giving rise to said draft, either at the time of acceptance or payment or thereafter. LC Issuer is under no duty to determine the proper identity of anyone presenting such a draft or making such a demand (whether by tested telex or otherwise) as the officer, representative or Agent of any beneficiary under any Letter of Credit, and payment by LC Issuer to any such beneficiary when requested by any such purported officer, representative or Agent is hereby authorized and approved. Borrower releases each Lender Party from, and agrees to hold each Lender Party harmless and indemnified against, any liability or claim in connection with or arising out of the subject matter of this Section, which indemnity shall apply whether or not any such liability or claim is in any way or to any extent caused, in whole or in part, by any negligent act or omission of any kind by any Lender Party; provided only that no Lender Party shall be entitled to indemnification for that portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment by a court of competent jurisdiction.

(b) Extension of Maturity. If the maturity of any Letter of Credit is extended by its terms or by Law or governmental action, if any extension of the maturity or time for presentation of drafts or any other modification of the terms of any Letter of Credit is made at the request of any Restricted Person, or if the amount of any Letter of Credit is increased at the request of any Restricted Person, this Agreement shall be binding upon all Restricted Persons with respect to

38

such Letter of Credit as so extended, increased or otherwise modified, with respect to drafts and property covered thereby, and with respect to any action taken by LC Issuer, LC Issuer’s correspondents, or any Lender Party in accordance with such extension, increase or other modification.

(c) Transferees of Letters of Credit. If any Letter of Credit provides that it is transferable, LC Issuer shall have no duty to determine the proper identity of anyone appearing as transferee of such Letter of Credit, nor shall LC Issuer be charged with responsibility of any nature or character for the validity or correctness of any transfer or successive transfers, and payment by LC Issuer to any purported transferee or transferees as determined by LC Issuer is hereby authorized and approved, and Borrower releases each Lender Party from, and agrees to hold each Lender Party harmless and indemnified against, any liability or claim in connection with or arising out of the foregoing, which indemnity shall apply whether or not any such liability or claim is in any way or to any extent caused, in whole or in part, by any negligent act or omission of any kind by any Lender Party; provided only that no Lender Party shall be entitled to indemnification for that portion, if any, of any liability or claim which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment by a court of competent jurisdiction.

Section 2.14 LC Collateral.

(a) Acceleration of LC Obligations. If the Obligations or any part thereof become immediately due and payable pursuant to Section 8.1 then, unless Required Lenders otherwise specifically elect to the contrary (which election may thereafter be retracted by Required Lenders at any time), all LC Obligations shall be deemed to become immediately due and payable without regard to whether or not actual drawings or payments on the Letters of Credit have occurred, and Borrower shall be obligated to pay to LC Issuer immediately an amount equal to the aggregate LC Obligations which are then outstanding, which amount shall be held by LC Issuer as security for LC Obligations (the “LC Collateral”) and the other Obligations, and such LC Collateral may be applied from time to time to any Matured LC Obligations or any other Obligations which are due and payable.

(b) Investment of LC Collateral. Pending application thereof, all LC Collateral shall be invested by Agent in such Investments as Agent may choose in its sole discretion. All interest on (and other proceeds of) such Investments shall be reinvested or applied to Matured LC Obligations or other Obligations which are due and payable. When all Obligations have been satisfied in full, including all LC Obligations, all Letters of Credit have expired or been terminated, and all of Borrower’s reimbursement obligations in connection therewith have been satisfied in full or when the condition pursuant to which the LC Collateral was required no longer exists, Agent shall release any remaining LC Collateral. Borrower hereby assigns and grants to Agent a continuing security interest in all LC Collateral paid by it to Agent, all Investments purchased with such LC Collateral, and all proceeds thereof to secure its Matured LC Obligations and its Obligations under this Agreement, each Note, and the other Loan Documents, and Borrower agrees that such LC Collateral, Investments and proceeds shall be subject to all of the terms and conditions of the Security Documents. Borrower further agrees that Agent shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as adopted in the State of Texas with respect to such security interest and that

39

an Event of Default under this Agreement shall constitute a default for purposes of such security interest.

(c) Payment of LC Collateral. When Borrower is required to provide LC Collateral for any reason and fails to do so on the day when required, Agent or LC Issuer may without notice to Borrower or any other Restricted Person provide such LC Collateral (whether by application of proceeds of other Collateral, by transfers from other accounts maintained with Agent or LC Issuer, or otherwise) using any available funds of Borrower or any other Person also liable to make such payments. Any such amounts which are required to be provided as LC Collateral and which are not provided on the date required shall, for purposes of each Security Document, be considered past due Obligations owing hereunder, and LC Issuer is hereby authorized to exercise its respective rights under each Security Document to obtain such amounts.

Section 2.15 Existing Letters of Credit. On the effective date of this Agreement, without further action by any party hereto, the LC Issuer shall be deemed to have granted to each Revolving Lender, and each Revolving Lender shall be deemed to have acquired from the LC Issuer, a participation in each of the Existing Letters of Credit equal to such Lender’s Percentage Share of (a) the aggregate amount available to be drawn under such Existing Letters of Credit and (b) the aggregate amount of any outstanding reimbursement obligations in respect thereof. With respect to each of the Existing Letters of Credit, (i) if the LC Issuer has heretofore sold a participation therein to a Revolving Lender, the LC Issuer and such Lender agree that such participation shall be automatically canceled on the effective date of this Agreement and (ii) if the LC Issuer has heretofore sold a participation therein to any bank or financial institution that is not a Lender, then the LC Issuer shall procure the termination of such participation on or prior to the effective date of this Agreement. On and after the effective date of this Agreement, each of the Existing Letters of Credit shall be a Letter of Credit issued hereunder.

Section 2.16 Swingline Loans.

(a) Subject to the terms and conditions hereof, upon the request of Borrower from time to time during the Commitment Period, the Swingline Lender may, but will not be obligated to, make swingline loans (the “Swingline Loans”) to Borrower, notwithstanding the fact that such Swingline Loans, when aggregated with the Percentage Share of the Revolving Loans and LC Obligations of the Lender acting as Swingline Lender, may exceed such Lender’s Revolving Loan Commitment; provided, however that the (i) aggregate principal amount of outstanding Swingline Loans at any time outstanding shall not exceed $50,000,000, and (ii) Swingline Lender shall not be required to make a Swingline Loan to refinance an outstanding Swingline Loan. Notwithstanding the foregoing, the aggregate principal balance of the Revolving Loans and Swingline Loans outstanding at any time together with all LC Obligations shall not exceed the Aggregate Revolving Loan Commitment. Each Swingline Loan (i) shall be a Base Rate Loan, (ii) shall be made in the minimum amount of $100,000.00 and integral multiples thereof or in the amount of any unused portion of the Aggregate Revolving Loan Commitment, and (iii) may be repaid and, so long as no Default or Event of Default exists hereunder, reborrowed, at the option of Borrower in accordance with the provisions hereof. There shall be no further Borrowings under Swingline Loans after the Maturity Date.

40

(b) The Swingline Lender may by written notice given to Agent not later than 9:00 a.m. Houston, Texas time on any Business Day require the Revolving Lenders to acquire participations on such Business Day in all or a portion of the Swingline Loans outstanding. Such notice shall specify the aggregate amount of Swingline Loans in which the Revolving Lenders will participate. Promptly upon receipt of such notice, Agent will give notice thereof to each Revolving Lender, specifying in such notice such Lender’s Percentage Share of such Swingline Loan or Loans. Each Revolving Lender hereby absolutely and unconditionally agrees, upon receipt of notice as provided above, to pay to Agent, for the account of the Swingline Lender, such Lender’s Percentage Share of such Swingline Loan or Loans. Each Revolving Lender acknowledges and agrees that its obligation to acquire participations in Swingline Loans pursuant to this paragraph is absolute and unconditional and shall not be affected by any circumstance whatsoever, including the occurrence and continuance of a Default, Event of Default or reduction or termination of the Revolving Loan Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. Each Revolving Lender shall comply with its obligation under this paragraph by wire transfer of immediately available funds, in the same manner as provided in Section 2.2 with respect to Loans made by such Lender (and Section 2.2 shall apply, mutatis mutandis, to the payment obligations of the Revolving Lenders), and Agent shall promptly pay to the Swingline Lender the amounts so received by it from the Revolving Lenders. Agent shall notify Borrower of any participations in any Swingline Loan acquired pursuant to this paragraph, and thereafter payments in respect of such Swingline Loan shall be made to Agent and not to the Swingline Lender. Any amounts received by the Swingline Lender from Borrower (or other party on behalf of Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender of the proceeds of a sale of participations therein shall be promptly remitted to Agent; any such amounts received by Agent shall be promptly remitted by Agent to the Revolving Lenders that shall have made their payments pursuant to this paragraph and to the Swingline Lender, as their interests may appear; provided that any such payment so remitted shall be repaid to the Swingline Lender or to Agent, as applicable, if and to the extent such payment is required to be refunded to Borrower for any reason. The purchase of participations in a Swingline Loan pursuant to this paragraph shall not relieve Borrower of any default in the payment thereof.

(c) Whenever Borrower requests a Swingline Loan, it must deliver to Agent a Borrowing Notice as described in Section 2.2.

(d) Borrower’s obligation to repay the Swingline Loans made by the Swingline Lender shall be evidenced by a revolving credit promissory note duly executed and delivered by Borrower to the Swingline Lender substantially in the form of Exhibit 2.16 hereto (the “Swingline Note”), and the Swingline Note shall (i) be payable to the order of the Swingline Lender and be dated as of the Amendment No. 6 Effective Date, (ii) be in a stated principal amount equal to $50,000,000, (iii) prior to the Maturity Date, be payable as provided herein and mature on the Maturity Date, (iv) bear interest as provided in this Section 2.16 and (v) be entitled to the benefits of this Agreement and the other Loan Documents.

(e) Borrower hereby promises to pay all outstanding principal (and any accrued, unpaid interest) of any Swingline Loan on the earliest of (i) the Maturity Date, (ii) the first date after such Swingline Loan is made that is the last day of a calendar month and is at least two

41

Business Days after such Swingline Loan is made, and (iii) the first date that a Revolving Loan is made after the date of such Swingline Loan.

(f) The unpaid principal amount of each Swingline Loan shall bear interest at an annual rate equal to the Adjusted Base Rate in effect from time to time.

(g) The obligation of the Swingline Lender to make Swingline Loans to Borrower is subject to the same conditions precedent for the making of Loans under Section 4.2.

Section 2.17 Increase of Revolving Loan Commitments.

(a) Subject to Section 2.17(b), Borrower may increase the Aggregate Revolving Loan Commitment then in effect by entering into an Incremental Commitment Agreement with one or more banks or financial institutions (each an “Incremental Lender”), pursuant to which each such Incremental Lender’s Revolving Loan Commitment shall be increased or, if such Incremental Lender was not a Revolving Lender prior to entering such Incremental Commitment Agreement, pursuant to which such Incremental Lender makes and is allocated a Revolving Loan Commitment.

(b) Any increase in the Aggregate Revolving Loan Commitment pursuant to this Section 2.17 will be subject to the satisfaction of the following conditions:

(i) no Event of Default has occurred and is continuing;

(ii) Borrower and each Incremental Lender shall have executed and delivered an Incremental Commitment Agreement and each Incremental Lender, if not already a Lender, shall have delivered to Agent a completed administrative questionnaire;

(iii) Agent shall have delivered its prior written consent, which consent shall not be unreasonably withheld, to each such Incremental Lender, unless such Incremental Lender is already a Revolving Lender or an Affiliate of a Revolving Lender;

(iv) each such increase shall be at least $5,000,000;

(v) the cumulative increase in Revolving Loan Commitments pursuant to this Section 2.17 shall not exceed $150,000,000;

(vi) no event shall have occurred since the date of the audited financial statements most recently delivered pursuant to Section 6.2(a), with respect to Borrower and its Subsidiaries, taken as a whole, that has resulted, or could reasonably be expected to result, in a Material Adverse Change;

(vii) on the effective date of such increase, no Eurodollar Loan shall be outstanding or if any Eurodollar Loans are outstanding, then the effective date of such increase will be the last day of the Interest Period in respect of such Eurodollar Loans unless Borrower pays compensation pursuant to Section 3.5;

42

(viii) the aggregate amount of the Lenders’ Revolving Loan Commitments shall not exceed $600,000,000 without the approval of all Lenders; and

(ix) Agent shall have received such corporate resolutions of Borrower and legal opinions of counsel to Borrower as Agent may reasonably request with respect thereto, in each case in form and substance reasonably satisfactory to Agent.

(c) Upon the effectiveness of each Incremental Commitment Agreement executed by an Incremental Lender, (i) such Incremental Lender will become a Revolving Lender for all purposes and to the same extent as if originally a party hereto and will be bound by and entitled to the benefits of this Agreement, (ii) the Revolving Loan Commitments and Aggregate Revolving Loan Commitment will be deemed to include the new or increased Revolving Loan Commitment of such Incremental Lender, and (iii) such Incremental Lender shall purchase a pro rata portion of the outstanding Revolving Loans (and participation interests in Letters of Credit) from each of the other Revolving Lenders (and such Lenders hereby agree to sell and to take all such further action to effectuate such sale) so that each Revolving Lender (including each Incremental Lender) holds its Percentage Share of the Revolving Facility Usage.

(d) Upon its receipt of a duly completed Incremental Commitment Agreement, executed by Borrower and each Incremental Lender party thereto, and the administrative questionnaire referred to in Section 2.17(b)(ii), and subject to the satisfaction of the other conditions of this Section 2.17, Agent shall accept such Incremental Commitment Agreement and record the information contained therein in the Register. No increase in the aggregate Revolving Loan Commitments will be effective for purposes of this Agreement unless the relevant Incremental Commitment Agreement shall have been delivered to Agent.

Section 2.18 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions will apply for so long as that Lender is a Defaulting Lender:

(a) Such Defaulting Lender shall not be entitled to fees that would otherwise have accrued during such period under Section 2.5(c), and such fees shall cease to accrue during such period with respect to such Defaulting Lender’s unused Revolving Loan Commitment;

(b) the Revolving Loan Commitment and Percentage Share of Revolving Facility Usage and outstanding Term Loans of the Defaulting Lender will not be included in determining whether all Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 10.1), and the definition of “Required Lenders” will automatically be deemed modified accordingly for the duration of such period; provided, that any such amendment, waiver, determination, consent, or notification that would increase or extend the term of the Revolving Loan Commitment of such Defaulting Lender, extend the date fixed for the payment of principal or interest owing to such Defaulting Lender hereunder, reduce the principal amount of any Obligation owing to such Defaulting Lender, reduce the amount of or the rate or amount of interest on any amount owing to such Defaulting Lender or of any fee payable to such Defaulting Lender hereunder, or alter the terms of this proviso, will require the consent of the Defaulting Lender. If a Defaulting Lender’s consent to an amendment, waiver, determination, consent, or notification is required pursuant to

43

this Section 2.18 or any other provision in the Loan Documents, and such Defaulting Lender has failed to respond to a written request from Agent to approve such waiver, amendment, determination, consent, or notification for 10 Business Days after such Defaulting Lender’s receipt of such request, such Defaulting Lender will be deemed to have approved such amendment, waiver, determination, consent, or notification;

(c) if any Swingline Loan or LC Obligation exists at the time a Lender becomes a Defaulting Lender then:

(i) all or any part of such Swingline Loan or LC Obligation will be reallocated among the non-Defaulting Lenders that are Revolving Lenders in accordance with their respective Percentage Shares but only to the extent (x) the sum of all non-Defaulting Lenders’ Percentage Shares of the Revolving Facility Usage plus the portion of such Defaulting Lender’s Percentage Share of such Swingline Loan or LC Obligation to be reallocated does not exceed the total of all non-Defaulting Lenders’ Revolving Loan Commitments and (y) the conditions set forth in Section 4.2 are satisfied at that time; provided that, subject to Section 10.12, no reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a non-Defaulting Lender as a result of such non-Defaulting Lender’s increased exposure following such reallocation; and

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, Borrower shall within one Business Day following notice by Agent (x) first, prepay such Swingline Loans and (y) second, cash collateralize such Defaulting Lender’s Percentage Share of the LC Obligations (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.14 for so long as such LC Obligation is outstanding;

(iii) if Borrower cash collateralizes any portion of such Defaulting Lender’s Percentage Share of the LC Obligations pursuant to this Section 2.18(c), Borrower shall not be required to pay any fees to such Defaulting Lender or any other Person pursuant to Section 2.12 with respect to such cash collateralized portion of such Defaulting Lender’s Percentage Share of the LC Obligations during the period those LC Obligations are cash collateralized;

(iv) if LC Obligations are allocated to non-Defaulting Lenders pursuant to Section 2.18(c)(i), then the fees payable to the Revolving Lenders pursuant to Section 2.12 will be adjusted to reflect the non-Defaulting Lenders’ post-allocation Percentage Shares; or

(v) if any portion of any Defaulting Lender’s Percentage Share of the LC Obligations is neither cash collateralized pursuant to Section 2.18(c)(ii) nor reallocated pursuant to Section 2.18(c)(i), then, without prejudice to any rights or remedies of the LC Issuer or any Lender hereunder, any letter of credit fees payable under Section 2.12(a) with respect to such non-cash collateralized, unreallocated portion of such Defaulting Lender’s Percentage Share of the LC Obligations will be payable to the LC Issuer until

such portion of such Defaulting Lender’s Percentage Share of the LC Obligations is cash collateralized and/or reallocated or such Defaulting Lender ceases to be a Defaulting Lender;

(d) so long as any Lender is a Defaulting Lender, the Swingline Lender will not be required to fund any Swingline Loan and the LC Issuer will not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Revolving Loan Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by Borrower in accordance with Section 2.18(c)(ii), and participating interests in any such newly issued or increased Letter of Credit or newly made Swingline Loan will be allocated among non-Defaulting Lenders in a manner consistent with Section 2.18(c)(i) (and Defaulting Lenders will not participate therein);

(e) any amount payable to such Defaulting Lender hereunder (whether on account of principal, interest, fees or otherwise and including any amount that would otherwise be payable to such Defaulting Lender pursuant to Section 9.6 but excluding Section 3.8) shall, in lieu of being distributed to such Defaulting Lender, be retained by Agent in a segregated account and, subject to any applicable requirements of law, be applied at such time or times as may be determined by Agent (i) first, to the payment of any amounts owing by such Defaulting Lender to Agent hereunder, (ii) second, pro rata, to the payment of any amounts owing by such Defaulting Lender to the LC Issuer or Swingline Lender hereunder, (iii) third, to the funding of any Loan or the funding or cash collateralization of any participating interest in any Swingline Loan or Letter of Credit in respect of which such Defaulting Lender has failed to fund its portion as required by this Agreement, as determined by Agent, (iv) fourth, if so determined by Agent and Borrower, held in such account as cash collateral for future funding obligations of the Defaulting Lender under this Agreement, (v) fifth, pro rata, to the payment of any amounts owing to Borrower or the Lenders as a result of any judgment of a court of competent jurisdiction obtained by Borrower or any Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement and (vi) sixth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; and

(f) If there is not in existence a Default or Event of Default, Borrower may terminate the unused amount of the Revolving Loan Commitment of a Defaulting Lender upon not less than three Business Days’ prior notice to Agent (which will promptly notify the Lenders thereof); provided that such termination shall not be deemed to be a waiver or release of any claim Borrower, Agent, the LC Issuer, the Swingline Lender, or any Lender may have against such Defaulting Lender.

ARTICLE III

PAYMENTS TO LENDERS

Section 3.1 General Procedures. Borrower will make each payment which it owes under the Loan Documents to Agent for the account of the Lender Party to whom such payment is owed, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Each such payment must be received by Agent not later than 11:00 a.m., Houston, Texas time, on the date such payment becomes due

45

and payable. Any payment received by Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document shall be due and payable at the place set forth for Agent on the Lenders Schedule. When Agent collects or receives money on account of the Obligations, Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as follows (except as otherwise provided in Section 2.18(e) and Section 8.3):

(a) first, for the payment of all Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due Agent under Section 6.9 or 10.4 and then to the partial payment of all other Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree);

(b) then for the prepayment of amounts owing under the Loan Documents (other than principal of the Loans) if so specified by Borrower;

(c) then for the prepayment of principal of the Loans, together with accrued and unpaid interest on the principal so prepaid; and

(d) last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.6 and 2.7. Subject to Section 2.18(e), all distributions of amounts described in any of subsections (b), (c) or (d) above shall be made by Agent pro rata to each Lender Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection; provided that if any Lender then owes payments to LC Issuer for the purchase of a participation under Section 2.11(c) or to Agent under Section 9.4, any amounts otherwise distributable under this Section to such Lender shall be deemed to belong to LC Issuer, or Agent, respectively, to the extent of such unpaid payments, and Agent shall apply such amounts to make such unpaid payments rather than distribute such amounts to such Lender.

Section 3.2 Capital Reimbursement. If any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on any Lender Party’s capital, or on the capital of any corporation controlling such Lender Party, as a consequence of the Loans made, or Letters of Credit issued, by such Lender Party, to a level below that which such Lender Party or such corporation could have achieved but for such change (taking into consideration such Lender Party’s policies and the policies of any such corporation with respect to capital adequacy), then from time to time Borrower will pay to Agent for the benefit of such Lender Party, within five (5) Business Days of demand therefore by such Lender Party, such additional amount or amounts which such Lender Party shall determine to be appropriate to compensate such Lender Party for such reduction.

46

Section 3.3 Increased Cost of Eurodollar Loans or Letters of Credit.

(a) If any Change in Law:

(i) shall change the basis of taxation of payments to any Lender Party of any principal, interest, or other amounts attributable to any Eurodollar Loan or Letter of Credit or otherwise due under this Agreement in respect of any Eurodollar Loan or Letter of Credit (other than (x) Reimbursable Taxes, (y) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (z) Other Connection Taxes that are imposed on or measured by net income (however denominated) or that are franchise Taxes or branch profits Taxes); or

(ii) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any Eurodollar Loan made by any Lender Party or any Letter of Credit (excluding any reserve requirement included in the computation of the Adjusted LIBOR Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender Party; or

(iii) shall impose on any Lender Party or the interbank eurocurrency deposit market any condition affecting any Eurodollar Loan or Letter of Credit,

the result of which is to increase the cost to any Lender Party of agreeing to make or making, funding or maintaining Eurodollar Loans or (as the case may be) issuing or participating in Letters of Credit, or a reduction in the amount received or receivable by such Lender in connection with any of the foregoing, then such Lender Party shall promptly notify Agent and Borrower in writing of the happening of such event and of the amount required to compensate such Lender Party for such additional costs or reduced return, whereupon (i) Borrower shall pay such additional amount or amounts as will compensate such Lender Party for such additional costs incurred or reduction suffered to Agent for the account of such Lender Party and (ii) Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days’ notice, to convert all (but not less than all) of any such Eurodollar Loans of such Lender Party into Base Rate Loans.

(b) A certificate of a Lender Party setting forth the amount or amounts necessary to compensate such Lender Party or the corporation controlling such Lender Party, as the case may be, as specified in Section 3.2 or this Section 3.3 shall be delivered to Borrower and shall be conclusive absent manifest error. Borrower shall pay the applicable Lender Party the amount shown as due on any such certificate within 3 Business Days after receipt thereof.

(c) Failure or delay on the part of any Lender Party to demand compensation pursuant to Section 3.2 or this Section 3.3 shall not constitute a waiver of such Lender Party’s right to demand such compensation.

Section 3.4 Illegality. If any Change in Law shall make it unlawful for any Lender Party to fund or maintain Eurodollar Loans, then, upon notice by such Lender Party to Borrower and Agent, (a) Borrower’s right to elect Eurodollar Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, (b) all Eurodollar Loans of such Lender Party which are then the subject of any Borrowing Notice and which cannot be lawfully

47

funded shall be funded as Base Rate Loans of such Lender Party, and (c) all Eurodollar Loans of such Lender Party shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by Law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, Borrower shall pay to such Lender Party such amounts, if any, as may be required pursuant to Section 3.5.

Section 3.5 Funding Losses. In addition to its other obligations hereunder, Borrower will indemnify each Lender Party against, and reimburse each Lender Party on demand for, any loss or expense incurred or sustained by such Lender Party (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by a Lender Party to fund or maintain Eurodollar Loans but excluding any loss of Base Rate Margin or Eurodollar Margin), as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan made after the delivery, but before the effective date, of a Continuation/Conversion Notice requesting the continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans, if such payment or prepayment prevents such Continuation/Conversion Notice from becoming fully effective, (c) the failure of any Loan to be made or of any Continuation/Conversion Notice requesting the continuation of outstanding Eurodollar Loans as, or the conversion of outstanding Base Rate Loans to, Eurodollar Loans to become effective due to any condition precedent not being satisfied or due to any other action or inaction of any Restricted Person, (d) any Conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Eurodollar Loan into a Base Rate Loan or into a different Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, or (e) any assignment of a Eurodollar Loan on a day other than the last day of the Interest Period therefor as a result of a request by Borrower pursuant to Section 3.8(b).

Section 3.6 Reimbursable Taxes.

(a) For purposes of this Section, the term “Lender” includes any Issuing Bank and the term “applicable Law” shall include FATCA.

(b) Borrower will indemnify each Lender Party against and reimburse each Lender Party for all present and future Taxes imposed, assessed, levied or collected on or in respect of any obligation of any Restricted Person under any Loan Document (whether or not correctly or legally imposed), excluding, however, any of the following Taxes (i) Taxes imposed on or measured by net income (however denominated), franchise Taxes and branch profits Taxes, in each case, (A) imposed as a result of such Lender Party being organized under the Laws of, or having its principal office or, in the case of any Lender, its Applicable Lending Office located in, the jurisdiction imposing such Tax (or any political subdivision thereof) or (B) that are Other Connection Taxes, (ii) in the case of any Lender, any United States withholding Tax imposed on any amounts payable to or for the account of such Lender with respect to an applicable interest in a Loan or Commitment pursuant to a law in effect on the date on which (A) such Lender acquires such interest in any Loan or Revolving Loan Commitment (other than pursuant to an assignment request by Borrower under Section 3.8(b)) or (B) such Lender Party changes its Applicable

48

Lending Office, except in each case to the extent that, pursuant to this Section, amounts with respect to such Taxes were payable either to such Lender’s assignor immediately before such Lender became a party hereto or to such Lender immediately before it changed its Applicable Lending Office, (iii) Taxes attributable to such recipient’s failure to comply with requirements to deliver the Prescribed Forms as set forth Section 3.6(e) and (iv) any withholding Taxes imposed under FATCA (all such Taxes “Excluded Taxes”, and all other Taxes imposed on or with respect to any payment made by or on account of any obligation of Borrower under any Loan Document being collectively called “Reimbursable Taxes”). Such indemnification shall be on an after-Tax basis and, except as otherwise provided in this Section 3.6(b), such indemnification shall be paid within 10 Business Days after a Lender Party delivers a certificate demonstrating the amount of such payment or liability.

(c) All payments on account of the principal of, and interest on, each Lender Party’s Loans and Note, and all other amounts payable by Borrower to any Lender Party hereunder, shall be made without deductions or withholdings for any Taxes (except to the extent required by applicable Law). In the event of Borrower or Agent being compelled by applicable Law to make any such deduction or withholding of any Tax from any payment to any Lender Party pursuant to this Agreement, and if the Tax is a Reimbursable Tax, Borrower shall pay on the due date of such payment such additional amounts as are needed to cause the amount receivable by such Lender Party after such deduction or withholding to equal the amount which would have been receivable in the absence of such deduction or withholding. If Borrower should make any deduction or withholding as aforesaid, Borrower shall within 60 days thereafter forward to Agent an official receipt or other official document evidencing payment of such deduction or withholding.

(d) If Borrower is ever required to pay any Reimbursable Tax with respect to any Eurodollar Loan, Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days’ notice, to convert all (but not less than all) of any such Eurodollar Loan into a Base Rate Loan, but such election shall not diminish Borrower’s obligation to pay all Reimbursable Taxes.

(e) Notwithstanding the foregoing provisions of this Section, Borrower and Agent shall be entitled, to the extent such party is required to do so by applicable Law, to deduct or withhold (and not to make any indemnification or reimbursement for) Taxes imposed by the United States of America from interest, fees or other amounts payable hereunder for the account of any Lender Party, other than a Lender Party (i) who is a U.S. Person for Federal income Tax purposes that delivered to Agent executed originals of IRS Form W-9 certifying that such Lender Party is exempt from United States federal backup withholding Tax or (ii) who is a Foreign Lender and has the Prescribed Forms on file with Agent (with copies provided to Borrower) for the applicable year to the extent deduction or withholding of such Taxes is not required as a result of the filing of such Prescribed Forms; provided that if Borrower or Agent shall so deduct or withhold any such Taxes, Borrower or Agent, as applicable, shall provide a statement to Agent (if applicable) and such Lender Party, setting forth the amount of such Taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender Party may reasonably request for assisting such Lender Party to obtain any allowable credits or deductions for the Taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender Party is subject to tax. Borrower or Agent may from time to time reasonably request that any Lender Party that is a Foreign Lender deliver executed copies of any Prescribed Form to

49

permit Borrower or Agent to determine the withholding or deduction required to be made. If a payment made to a Lender Party under any Loan Document would be subject to United States federal withholding Tax imposed by FATCA if such Lender Party were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Internal Revenue Code, as applicable), such Lender Party shall deliver to Borrower and Agent at the time or times prescribed by applicable Law and at such time or times reasonably requested by Borrower or Agent such documentation prescribed by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Internal Revenue Code) and such additional documentation reasonably requested by Borrower or Agent as may be necessary for Borrower and Agent to comply with their obligations under FATCA and to determine that such Lender Party has complied with such Lender Party’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. For the avoidance of doubt, for purposes of determining withholding Taxes imposed under FATCA, Borrower, its Guarantors, and Agent shall treat (and the Lenders hereby authorize Agent to treat) this Agreement as not qualifying as a “grandfathered obligation” within the meaning of Treasury Regulation Section 1.1471-2(b)(2)(i). Solely for purposes of this clause (e), “FATCA” shall include any amendments made to FATCA after the Amendment No. 6 Effective Date.

Each Lender Party agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify Borrower and Agent in writing of its legal inability to do so.

(f) If any party determines, in its sole discretion exercised in good faith, that it has received a refund (or credit in lieu of cash refund) of any Taxes as to which it has been indemnified pursuant to this Section 3.6 (including by the payment of additional amounts pursuant to this Section 3.6), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (e) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (e), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (e) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

Section 3.7 Changed Circumstances.

50

(a) Circumstances Affecting LIBOR Availability. Subject to clause (b) below, in connection with any request for a Eurodollar Loan or a conversion to or continuation thereof or otherwise, if for any reason:

(i) Agent determines 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 (any such determination shall be conclusive absent manifest error);

(ii) Agent determines that adequate and reasonable means do not exist for ascertaining LIBOR for such Interest Period (any such determination shall be conclusive absent manifest error); or

(iii) Agent is advised by Required Lenders that LIBOR for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then Agent shall give notice thereof to Borrower and Lenders by telephone or telecopy as promptly as practicable thereafter and, until Agent notifies Borrower and Lenders that the circumstances giving rise to such notice no longer exist, (A) any Continuation/Conversion Notice that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Borrowing of Eurodollar Loans shall be ineffective and shall be deemed a request to continue such Borrowing as a Borrowing of Base Rate Loans and (B) if any Borrowing Notice requests a Borrowing of Eurodollar Loans, such Borrowing shall be made as a Borrowing of Base Rate Loans. Upon receipt of such notice, Borrower may revoke any pending request for a Borrowing of, conversion to or continuation of Eurodollar Loans.

(b) Effect of Benchmark Transition Event.

(i) Benchmark Replacement. Notwithstanding anything to the contrary herein or in any other Loan Document, upon the occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, Agent and Borrower may amend this Agreement to replace LIBOR with a Benchmark Replacement. Any such amendment with respect to a Benchmark Transition Event will become effective at 5:00 p.m. on the fifth (5th) Business Day after Agent has posted such proposed amendment to all Lenders and Borrower so long as Agent has not received, by such time, written notice of objection to such amendment from Lenders comprising the Required Lenders. Any such amendment with respect to an Early Opt-in Election will become effective on the date that Lenders comprising the Required Lenders have delivered to Agent written notice that such Required Lenders accept such amendment. No replacement of LIBOR with a Benchmark Replacement pursuant to this Section 3.7(b) will occur prior to the applicable Benchmark Transition Start Date.

(ii) Benchmark Replacement Conforming Changes. In connection with the implementation of a Benchmark Replacement, Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary herein or in any other Loan Document, any amendments

51

implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement.

(iii) Notices; Standards for Decisions and Determinations. Agent will promptly notify Borrower and the Lenders of (A) any occurrence of a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date and Benchmark Transition Start Date, (B) the implementation of any Benchmark Replacement, (C) the effectiveness of any Benchmark Replacement Conforming Changes and (D) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by Agent or Lenders pursuant to this Section 3.7(b), including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party hereto, except, in each case, as expressly required pursuant to this Section 3.7(b).

(iv) Benchmark Unavailability Period. Upon Borrower’s receipt of notice of the commencement of a Benchmark Unavailability Period, Borrower may revoke any request for a Eurodollar Loan or conversion to or continuation of Eurodollar Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing that, Borrower will be deemed to have converted any such request into a request for a borrowing of or conversion to Base Rate Loans. During any Benchmark Unavailability Period, the component of the Base Rate based upon LIBOR will not be used in any determination of the Base Rate.

Section 3.8 Change of Applicable Lending Office; Replacement of Lenders.

(a) Each Lender Party agrees that, upon the occurrence of any event giving rise to the operation of Sections 3.2, 3.3, 3.4 or 3.6 with respect to such Lender Party, it will, if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender Party) to designate another Applicable Lending Office, provided that such designation is made on such terms that such Lender Party and its Applicable Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such Section. Nothing in this Section shall affect or postpone any of the obligations of Borrower or the rights of any Lender Party provided in Sections 3.2, 3.3, 3.4 or 3.6.

(b) If any Lender requests compensation under Section 3.2 or 3.3, or if Borrower is required to pay any additional amount to any Lender Party or any governmental authority for the account of any Lender Party pursuant to Section 3.6, or if the obligation of any Lender Party to make or maintain Loans as, or convert Loans to, Eurodollar Loans is suspended pursuant to Section 3.4, or if any Lender Party is a Defaulting Lender, then Borrower may, at its sole expense and effort (such expense to include any transfer fee payable to Agent under Section 10.5(c) and any expense pursuant to Article III), upon notice to such Lender Party and Agent, require such Lender Party to assign and delegate in whole (but not in part), without recourse (in accordance with and subject to the restrictions contained in Section 10.5), all its interests, rights and

52

obligations under this Agreement to an Eligible Transferee that shall assume such obligations (which Eligible Transferee may be another Lender Party, if a Lender Party accepts such assignment); provided that (i) Borrower shall have received the prior written consent of Agent, which consent shall not unreasonably be withheld, (ii) such Lender Party shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder from Borrower or such Eligible Transferee (including any amounts payable pursuant to Section 3.5), (iii) in the case of any such assignment resulting from a claim for compensation under Section 3.2 or 3.3 or payments required to be made pursuant to Section 3.6, such assignment will result in a reduction in such compensation or payments, and (iv) if Borrower elects to exercise such right with respect to any Lender Party, that has made such a request under Section 3.2, 3.3, 3.4 or 3.6, it shall be obligated to replace all Lender Parties that have made similar requests. A Lender Party shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender Party or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply. Any Lender Party being replaced shall execute and deliver an Assignment and Acceptance with respect to such Lender Party’s outstanding Loans and participations in LC Obligations.

No financial statement, material report, material certificate or other material information furnished (whether in writing or orally) by or on behalf of any Restricted Person to Agent or any Lender in connection with the transactions contemplated hereby and the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished), taken together as a whole, contains any untrue statement of a material fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to projected financial information, pro forma financial information, estimated financial information and other projected or estimated information, such information was prepared in good faith based upon assumptions believed to be reasonable at the time (it being recognized by the Lenders that projections are not to be viewed as facts and that the actual results during the period or periods covered by such projections may vary from such projections). As of the Amendment No. 6 Effective Date, the information included in each Beneficial Ownership Certification (if any) provided to Agent or any Lender in connection with this Agreement is true and correct.

Section 5.9 Litigation. Except as disclosed in the Initial Financial Statements or in Section 5.9 of the Disclosure Schedule, (a) there are no actions, suits or legal, equitable, arbitrative or administrative proceedings pending, or to the knowledge of any Restricted Person threatened, against any Restricted Person or affecting any Collateral (including any which challenge or otherwise pertain to any Restricted Person’s title to any Collateral) before any Tribunal which could reasonably be expected to cause a Material Adverse Change, and (b) there are no outstanding judgments, injunctions, writs, rulings or orders by any such Tribunal against any Restricted Person or, to the knowledge of Borrower, any Restricted Person’s stockholders, partners, directors or officers, or affecting any Collateral or any of its material assets or property which could reasonably be expected to cause a Material Adverse Change.

Section 5.10 Labor Disputes and Acts of God. Except as disclosed in Section 5.10 of the Disclosure Schedule, neither the business nor the properties of any Restricted Person has

56

been affected by any fire, explosion, accident, strike, lockout or other labor dispute, drought, storm, hail, earthquake, embargo, act of God or of the public enemy or other casualty (whether or not covered by insurance), which could reasonably be expected to cause a Material Adverse Change.

Section 5.11 ERISA Plans and Liabilities. Except as disclosed in the Initial Financial Statements or in Section 5.11 of the Disclosure Schedule, no Termination Event has occurred with respect to any ERISA Plan and all ERISA Plans are in compliance with ERISA unless the aggregate effect of all Termination Events and failures to comply with ERISA could not reasonably be expected to cause a Material Adverse Change. Except as permitted under Section 7.10 hereof, no ERISA Affiliate is required to contribute to, or has any other absolute or contingent liability in respect of, any “multiemployer plan” as defined in Section 4001 of ERISA. The payment by a Restricted Person of the sum of the contributions to each ERISA Plan that would be necessary for the “adjusted funding target attainment percentage” (within the meaning of Section 436 of the Internal Revenue Code) of each such ERISA Plan to equal 100 percent could not reasonably be expected to cause a Material Adverse Change. Each representation with respect to a “multiemployer plan” is made to Borrower’s knowledge.

Section 5.12 Environmental and Other Laws. Except as disclosed in Section 5.12 of the Disclosure Schedule: (a) Restricted Persons are conducting their businesses in compliance with all applicable Laws, including Environmental Laws, where the failure to so comply could reasonably be expected to cause a Material Adverse Change, and have and are in compliance with all licenses and permits required under any such Laws where the failure to so comply could reasonably be expected to cause a Material Adverse Change; (b) none of the operations or properties of any Restricted Person is the subject of federal, state or local investigation evaluating whether any material remedial action is needed to respond to a release of any Hazardous Materials into the environment or to the improper storage or disposal (including storage or disposal at offsite locations) of any Hazardous Materials which could reasonably be expected to cause a Material Adverse Change; (c) no Restricted Person (and to the best knowledge of Borrower, no other Person) has filed any notice under any Law indicating that any Restricted Person is responsible for the improper release into the environment, or the improper storage or disposal, of any material amount of any Hazardous Materials or that any Hazardous Materials have been improperly released, or are improperly stored or disposed of, upon any property of any Restricted Person which could reasonably be expected to cause a Material Adverse Change; (d) to the knowledge of Borrower, no Restricted Person has transported or arranged for the transportation of any Hazardous Material to any location which is (i) listed on the National Priorities List under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, listed for possible inclusion on such National Priorities List by the Environmental Protection Agency in its Comprehensive Environmental Response, Compensation and Liability Information System List, or listed on any similar state list or (ii) the subject of federal, state or local enforcement actions or other investigations, in the case of either of the forgoing clauses (i) and (ii), which may lead to claims against any Restricted Person for clean-up costs, remedial work, damages to natural resources or for personal injury claims (whether under Environmental Laws or otherwise) which could reasonably be expected to cause a Material Adverse Change; and (e) no Restricted Person otherwise has any known material contingent liability under any Environmental Laws or in connection with the release into the environment, or the storage or disposal, of any Hazardous Materials which could reasonably be

57

expected to cause a Material Adverse Change. Each Restricted Person undertook, at the time of its acquisition of each of its material properties, all appropriate inquiry into the previous ownership and uses of the property and any potential environmental liabilities associated therewith.

Section 5.13 Names and Places of Business. As of the Amendment No. 6 Effective Date, no Restricted Person has, during the preceding two (2) years, been known by, or used any other trade or fictitious name, except as disclosed in Section 5.13 of the Disclosure Schedule.

Except as indicated in Section 5.13 of the Disclosure Schedule or otherwise disclosed in writing to Agent, no Restricted Person has any other office or place of business.

Section 5.14 Subsidiaries. As of the Amendment No. 6 Effective Date, Borrower does not presently have any Subsidiary except those listed in Section 5.14 of the Disclosure Schedule or disclosed to Agent in writing. No Restricted Person has any equity investments in any other Person except those listed in Section 5.14 of the Disclosure Schedule or otherwise permitted under this Agreement. Borrower owns, directly or indirectly, the equity interests in each of its Subsidiaries indicated in Section 5.14 of the Disclosure Schedule or as disclosed to Agent in writing.

Section 5.15 Government Regulation. Neither Borrower nor any other Restricted Person owing Obligations is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The pledge of the Equity of each Subsidiary of Borrower does not violate Regulation T, U, or X of the Board of Governors of the Federal Reserve System.

Section 5.16 Insider. No Restricted Person, nor, to the knowledge of Borrower as of the Closing Date, any Person having “control” (as that term is defined in 12 U.S.C. § 375b(9) or in regulations promulgated pursuant thereto) of any Restricted Person, is a “director” or an “executive officer” or “principal shareholder” (as those terms are defined in 12 U.S.C. § 375b(8) or (9) or in regulations promulgated pursuant thereto) of any Lender, of a bank holding company of which any Lender is a Subsidiary or of any Subsidiary of a bank holding company of which any Lender is a Subsidiary.

Section 5.17 Solvency. Upon giving effect to the issuance of the Notes, the execution of the Loan Documents by Borrower and each Guarantor and the consummation of the transactions contemplated hereby, Borrower and the Guarantors, on a Consolidated basis, will be Solvent. Neither Borrower nor any Restricted Person has incurred (whether under the Loan Documents or otherwise), nor does any Restricted Person intend to incur or believe that it will incur Liabilities which will be beyond its ability to pay as such debts mature.

Section 5.18 [Reserved].

58

Section 5.19 Title to Properties; Licenses. Each Restricted Person has good and defensible title to all of the Collateral and to all of its material properties and assets, free and clear of all Liens, encumbrances, or adverse claims other than Permitted Liens and free and clear of all impediments to the use of such properties and assets in such Restricted Person’s business. Each Restricted Person possesses all licenses, permits, franchises, patents, copyrights, trademarks and trade names, and other intellectual property (or otherwise possesses the right to use such intellectual property without violation of the rights of any other Person) which are necessary to carry out its business as presently conducted and as presently proposed to be conducted hereafter, except to the extent failure to possess such licenses, permits, franchises, patents, copyrights, trademarks and trade names, and other intellectual property could reasonably be expected to cause a Material Adverse Change and no Restricted Person is in violation of the terms under which it possesses such intellectual property or the right to use such intellectual property, the violation of which could reasonably be expected to cause a Material Adverse Change.

Section 5.20 Regulation U. None of Borrower and its Subsidiaries are engaged in the business of extending credit for the purpose of purchasing or carrying Margin Stock, and no proceeds of any Loans will be used for a purpose which violates Regulation U.

Section 5.21 Taxes. Each Restricted Person has timely filed or caused to be filed all material Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which such Restricted Person, as applicable, has set aside on its books adequate reserves in accordance with GAAP and (b) Taxes which individually or in the aggregate do not exceed $3,000,000.

(e) Each Restricted Person will cooperate with Agent in connection with the publication of certain materials and/or information provided by or on behalf of each such Restricted Person to Agent and Lenders (collectively, the “Information Materials”) pursuant to this Article VI and will, at the reasonable request of Agent, designate Information Materials (i) that are either available to the public or not material with respect to any Restricted Person or any of their respective securities for purposes of United States federal and state securities laws, as “Public Information” and (ii) that are not Public Information as “Private Information.” If any Information Materials are not labeled “Public Information,” they shall be deemed to be labeled “Private Information”.

Section 6.3 Other Information and Inspections. Each Restricted Person will furnish to each Lender any information which Agent may from time to time reasonably request concerning any provision of the Loan Documents, any Collateral, or any matter in connection with Restricted Persons’ businesses, properties, prospects, financial condition and operations, including all evidence which Agent from time to time reasonably requests in writing as to the accuracy and validity of or compliance with all representations, warranties and covenants made by any Restricted Person in the Loan Documents, the satisfaction of all conditions contained therein, and all other matters pertaining thereto. Each Restricted Person will permit representatives appointed by Agent (including independent accountants, auditors, Agents, attorneys, appraisers and any other Persons) to visit and inspect during normal business hours any of such Restricted Person’s property, including its books of account, other books and records, and any facilities or other business assets, and to make extra copies therefrom and photocopies and photographs thereof, and to write down and record any information such representatives obtain, and each Restricted Person shall permit Agent or its representatives to investigate and verify the accuracy of the information furnished to Agent or any Lender in connection with the Loan Documents and to discuss all such matters with its officers, employees and representatives.

(a) the occurrence of any Material Adverse Change,

Upon the occurrence of any of the foregoing, the Restricted Persons will take all necessary or appropriate steps to promptly remedy any such Material Adverse Change, Default, Event of Default, acceleration, default or Termination Event (to the extent such Termination Event can be remedied), to protect against any such adverse claim, to defend any such suit or proceeding, and to resolve all controversies on account of any of the foregoing.

Each Restricted Person will (a) timely file all material required tax returns including any material extensions; (b) timely pay all material Taxes, assessments, and other governmental charges or levies imposed upon it or upon its income, profits or property before the same become delinquent, except to the extent such Taxes, assessments, or other charges or levies are being contested in good faith and reserves are maintained therefor to the extent required by GAAP; and (c) maintain appropriate accruals and reserves for all of the foregoing in accordance with GAAP.

Each Restricted Person will, if so requested by Agent, deliver to Agent original or duplicate policies of such insurance. Agent is hereby authorized to enforce payment under all such insurance policies and to compromise and settle any claims thereunder, in its own name or in the name of the Restricted Persons.

(c) Any proceeds paid under any liability insurance policy maintained by Restricted Persons pursuant to this Section 6.8 may be paid directly to the Person who has incurred the liability covered by such insurance.

(d) Any proceeds paid under a property or casualty insurance policy maintained by a Restricted Person pursuant to this Section 6.8 will be paid as follows:

(i) if an Event of Default exists, then such proceeds shall be paid to Agent; and

63

certificate are not received by Agent within 30 days of the cure or waiver of such Event of Default or (y) such Event of Default is not cured or waived within 365 days of Agent’s receipt of such funds, then Agent shall apply such funds to the prepayment of the Term Loans.

If any Restricted Person fails to pay any Taxes, insurance premiums, expenses, attorneys’ fees or other amounts it is required to pay under any Loan Document, Agent may pay the same. Borrower shall immediately reimburse Agent for any such payments and each amount paid by Agent shall constitute an Obligation owed hereunder which is due and payable on the date such amount is paid by Agent.

Section 6.10 Default Interest. Borrower hereby promises to each Lender Party to pay interest at the Default Rate on all Obligations (including Obligations to pay fees or to reimburse or indemnify any Lender) which Borrower has in this Agreement promised to pay to such Lender Party and which are not paid when due, after the expiration of any grace period for such payment set forth in Section 8.1. Such interest shall accrue from the expiration of any such grace period until such Obligations are paid.

Section 6.11 Compliance with Law. Each Restricted Person will conduct its business and affairs in compliance with all Laws applicable thereto, except as could not reasonably be expected to cause a Material Adverse Change. Each Restricted Person will cause all licenses and permits necessary or appropriate for the conduct of its business and the ownership and operation of its property used and useful in the conduct of its business to be at all times maintained in good standing and in full force and effect, except as could not reasonably be expected to cause a Material Adverse Change.

No Restricted Person will do anything or permit anything to be done which will subject any of its properties to any remedial obligations under, or result in noncompliance with applicable permits and licenses issued under, any applicable Environmental Laws, assuming disclosure to the applicable governmental authorities of all relevant facts, conditions and circumstances (except as could not reasonably be expected to result in a Material Adverse Change).

64

(b) Borrower will promptly furnish to Agent copies of all written notices of violation, orders, claims, citations, complaints, penalty assessments, suits or other proceedings received by any Restricted Person, or of which Borrower otherwise has notice, pending or threatened against any Restricted Person by any governmental authority with respect to any alleged violation of or non-compliance with any Environmental Laws or with respect to any permits, licenses or authorizations in connection with any Restricted Person’s ownership or use of its properties or the operation of its business, in each case, that could reasonably be expected to result in a Material Adverse Change.

(c) Borrower will promptly furnish to Agent all written requests for information, notices of claim, demand letters, and other written notifications, received by Borrower in connection with any Restricted Person’s ownership or use of its properties or the conduct of its business, relating to potential responsibility with respect to any investigation or clean-up of Hazardous Material at any location that could reasonably be expected to have a Material Adverse Change.

The remedies of foreclosure and offset are separate and cumulative, and either may be exercised independently of the other without regard to procedures or restrictions applicable to the other.

Section 6.15 Guaranties of Borrower’s Subsidiaries. Each Subsidiary (other than an Excluded Subsidiary) created, acquired or coming into existence after the date hereof (including any Subsidiary that ceases to be an Excluded Subsidiary) shall, within sixty (60) days thereof (or such longer period as may be approved by Agent in its reasonable discretion), execute and deliver to Agent an absolute and unconditional guaranty of the timely repayment of the Secured Obligations and the due and punctual performance of the Secured Obligations, which guaranty shall be in substantially the same form as the Guaranty entered into as of the Closing Date or otherwise reasonably satisfactory to Agent in form and substance.

(h) Any Restricted Person (i) fails to pay any portion, when such portion is due, of any of its Indebtedness in excess of $10,000,000, or (ii) breaches or defaults in the performance of any agreement or instrument by which any such Indebtedness is issued, evidenced, governed, or secured, and any such failure, breach or default continues beyond any applicable period of grace provided therefor;

(j) Any Restricted Person:

(i) suffers the entry against it of a judgment, decree or order for relief by a Tribunal of competent jurisdiction in an involuntary proceeding commenced under any

(k) Any Change of Control occurs;

(l) The occurrence of an event of default under any document to which any Restricted Person and any surety are both parties that, with the passage of time, would permit foreclosure by such surety on a material portion of the Collateral.

Upon the occurrence of an Event of Default described in subsection (j)(i), (j)(ii) or (j)(iii) of this Section with respect to Borrower, all of the Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Restricted Person who at any time ratifies or approves this Agreement.

During the continuance of any other Event of Default, Agent at any time and from time to time may (and

73

upon written instructions from Required Lenders, Agent shall), without notice to Borrower or any other Restricted Person, do either or both of the following: (1) terminate any obligation of Lenders to make Loans hereunder, and any obligation of LC Issuer to issue Letters of Credit hereunder, and (2) declare any or all of the Obligations immediately due and payable, and all such Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Restricted Person who at any time ratifies or approves this Agreement.

Section 8.2 Remedies. If any Event of Default shall occur and be continuing, each Lender Party may terminate its Revolving Loan Commitment and protect and enforce its rights under the Loan Documents by any appropriate proceedings, including proceedings for specific performance of any covenant or agreement contained in any Loan Document, and each Lender Party may enforce the payment of any Obligations due it or enforce any other legal or equitable right which it may have. All rights, remedies and powers conferred upon Lender Parties under the Loan Documents shall be deemed cumulative and not exclusive of any other rights, remedies or powers available under the Loan Documents or at Law or in equity. Notwithstanding the foregoing, the right to credit bid the Obligations in connection with any foreclosure sale or sale in a bankruptcy proceeding may only be exercised by Agent acting at the direction of the Required Lenders unless the Required Lenders agree that a Lender may credit bid its Obligations in connection with such a sale.

Section 8.3 Application of Proceeds after Acceleration. Except as otherwise provided in the Security Documents with respect to application of proceeds to any reimbursements due Agent thereunder and to the Lender Hedging Obligations, if Agent collects or receives money on account of the Secured Obligations after the acceleration of the Secured Obligations as provided in Section 8.1, Agent shall distribute all money so collected or received:

(a) First, to payment of that portion of the Secured Obligations constituting fees, indemnities, expenses and other amounts, including attorney fees, payable to Agent in its capacity as such;

(e) Fifth, to the payment of that portion of the Secured Obligations constituting Lender Bank Services Obligations, ratably among the Secured Parties to whom such Secured Obligations are owed; provided that Agent shall have no independent responsibility to determine the existence or amount of Lender Bank Services Obligations and may reserve from the application of amounts under this Section amounts distributable in respect of Lender Bank Services Obligations until it has received evidence satisfactory to it of the existence and amount of such Lender Bank Services Obligations; provided, further, however, that Agent may rely on statements of the Secured Parties as to the existence and amounts of Lender Bank Services Obligations owing to them;

ARTICLE IX

AGENT

Section 9.1 Appointment and Authority. Each Lender Party hereby irrevocably authorizes Agent, and Agent hereby undertakes, to receive payments of principal, interest and other amounts due hereunder as specified herein and to take all other actions and to exercise such powers under the Loan Documents as are specifically delegated to Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. The relationship of Agent to the other Lender Parties is only that of one commercial lender acting as Agent for others, and nothing in the Loan Documents shall be construed to constitute Agent a trustee or other fiduciary for any Lender Party or any holder of any participation in a Note nor to impose on Agent duties and obligations other than those expressly provided for in the Loan Documents. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of Agent, Agent shall not be required to exercise any discretion or take any action, and it may request instructions from Lenders with respect to any

75

such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Lender Parties in so acting or refraining from acting) upon the instructions of Required Lenders (including itself), provided, however, that Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable Law.

Section 9.2 Exculpation, Agent’s Reliance, Etc. Neither Agent nor any of its directors, officers, Agents, attorneys, or employees shall be liable for any action taken or omitted to be taken by any of them under or in connection with the Loan Documents, including their negligence of any kind, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Agent (a) shall treat the Person whose name is set forth on the Register as the holder of any Obligation as the holder thereof until Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such Person and in the form required under Section 10.5(c) and in form satisfactory to Agent; (b) may consult with legal counsel (including counsel for Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any other Lender and shall not be responsible to any other Lender Party for any statements, warranties or representations made in or in connection with the Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of the Loan Documents on the part of any Restricted Person or to inspect the property (including the books and records) of any Restricted Person; (e) shall not be responsible to any other Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any instrument or document furnished in connection therewith; (f) may rely upon the representations and warranties of each Restricted Person or Lender Party in exercising its powers hereunder; and (g) shall incur no liability under or in respect of the Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (including any facsimile, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons.

Section 9.3 Credit Decisions. Each Lender Party acknowledges that it has, independently and without reliance upon any other Lender Party, made its own analysis of Borrower and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender Party also acknowledges that it will, independently and without reliance upon any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents.

Section 9.4 Indemnification. Each Lender agrees to indemnify Agent (to the extent not reimbursed by Borrower within ten (10) days after demand) from and against such Lender’s Percentage Share of any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this Section collectively called “liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against Agent growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and

76

events (including the enforcement thereof) at any time associated therewith or contemplated therein (whether arising in contract or in tort and otherwise and including any violation or noncompliance with any Environmental Laws by any Person or any liabilities or duties of any Person with respect to Hazardous Materials found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,

provided only that no Lender shall be obligated under this Section to indemnify Agent for that portion, if any, of any liabilities and costs which is proximately caused by Agent’s own individual gross negligence or willful misconduct, as determined by a court of competent jurisdiction in a final and nonappealable judgment. Cumulative of the foregoing, each Lender agrees to reimburse Agent promptly upon demand for such Lender’s Percentage Share of any costs and expenses to be paid to Agent by Borrower under Section 10.4(a) to the extent that Agent is not timely reimbursed for such expenses by Borrower as provided in such Section. As used in this Section the term “Agent” shall refer not only to the Person designated as such in Section 1.1 but also to each director, officer, Agent, attorney, employee, representative and Affiliate of such Person.

Section 9.5 Rights as Lender. In its capacity as a Lender, Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not Agent. Agent may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with any Restricted Person or their Affiliates, all as if it were not Agent hereunder and without any duty to account therefor to any other Lender.

Section 9.6 Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether through the exercise of rights under Security Documents or rights of banker’s lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Agent under Section 3.1, causes such Lender Party to have received more than it would have received had such payment been received by Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Agent and all Lender Parties share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker’s lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker’s lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this Section is thereafter recovered from the seller under this Section which received the same, the purchase

77

provided for in this Section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to the order of a Tribunal order to be paid on account of the possession of such funds prior to such recovery.

Section 9.7 Investments. Whenever Agent in good faith determines that it is uncertain about how to distribute to Lender Parties any funds which it has received, or whenever Agent in good faith determines that there is any dispute among Lender Parties about how such funds should be distributed, Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to Lender Parties, Agent shall invest such funds pending distribution; all interest on any such Investment shall be distributed upon the distribution of such Investment and in the same proportion and to the same Persons as such Investment. All monies received by Agent for distribution to Lender Parties (other than to the Person who is Agent in its separate capacity as a Lender Party) shall be held by Agent pending such distribution solely as Agent for such Lender Parties, and Agent shall have no equitable title to any portion thereof.

Section 9.8 Benefit of Article IX. The provisions of this Article (other than the following Section 9.9) are intended solely for the benefit of Lender Parties, and no Restricted Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Lender. Lender Parties may waive or amend such provisions as they desire without any notice to or consent of Borrower or any Restricted Person.

Section 9.9 Resignation. Agent may resign at any time by giving written notice thereof to Lenders and Borrower. Each such notice shall set forth the date of such resignation. Upon any such resignation, Required Lenders shall have the right to appoint (with, unless an Event of Default shall have occurred and be continuing, the consent of Borrower, such consent not to be unreasonably withheld or delayed) a successor Agent. A successor must be appointed for any retiring Agent, and such Agent’s resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Agent’s resignation, no successor Agent has been appointed and has accepted such appointment, then the retiring Agent may appoint (with, unless an Event of Default shall have occurred and be continuing, the consent of Borrower, such consent not to be unreasonably withheld or delayed) a successor Agent, which shall be a commercial bank organized or licensed to conduct a banking or trust business under the Laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Agent’s resignation hereunder the provisions of this Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents.

Section 9.10 Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any Default, except with respect to defaults in the payment of principal, interest and fees required to be paid to Agent for the account of Lenders, unless Agent shall have received written notice from a Lender or Borrower referring to this Agreement, describing such Default and stating that such notice is a “notice of default.” Agent will notify Lenders of its receipt of any such notice. Agent shall take such action with respect to such Default as may be

78

directed by Required Lenders in accordance with Article VIII; provided, however, that unless and until Agent has received any such direction, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable or in the best interest of Lenders.

Section 9.11 Co-Agents. The Parties identified on the facing page of this Agreement as “Lead Arranger,” “Syndication Agent” or “Documentation Agent” have no right, power, obligation, liability, responsibility, or duty under the Loan Documents in such capacity. Without limiting the foregoing, each Party so identified as “Lead Arranger,” “Syndication Agent” or “Documentation Agent” shall not have and shall not be deemed to have any fiduciary relationship with any other Lender. Each Lender acknowledges that it has not relied, and will not rely, on taking or not taking action hereunder.

ARTICLE X

MISCELLANEOUS

Section 10.1 Waivers and Amendments; Acknowledgments.

(a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this Section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or further notice or demand in similar or other circumstances. No waiver, consent, or amendment of this Agreement or the other Loan Documents shall be valid or effective unless the same is in writing and signed by Borrower and the Required Lenders; provided, however, subject to Section 2.18 to the extent applicable, no such waiver, consent, or amendment shall (i) increase the maximum amount which any Lender is committed hereunder to lend without the written consent of such Lender, (ii) reduce any fees payable to any Lender hereunder, or the principal of, or interest on, such Lender’s Notes without the written consent of such Lender (provided that Agent and Borrower may, without the consent of any Lender, enter into amendments or modifications to this Agreement or any of the other Loan Documents or enter into additional Loan Documents as Agent reasonably deems appropriate in order to implement any Benchmark Replacement or any Benchmark Replacement Conforming Changes or otherwise effectuate the terms of Section 3.7(b) in accordance with the terms of Section 3.7(b)), (iii) extend the Maturity Date, or postpone any date fixed for any payment of any such fees, principal or interest (other than the date of any prepayment required pursuant to Section 2.7(b)), without the written consent of each Lender affected thereby, (iv) amend the definition herein of “Required Lenders” or otherwise change the aggregate amount of Percentage Shares which is required for Agent, Lenders or any of them to take any particular action under the Loan Documents without the written consent of each Lender, (v) release any Guarantor from any Guaranty (other than a Guarantor which ceases to be a

79

Subsidiary pursuant to a sale or other disposition permitted by the Loan Documents or that is designated as an Unrestricted Subsidiary in accordance with the definition of such term) without the written consent of each Lender, (vi) release all or substantially all of the Collateral (except for such releases relating to sales or dispositions of property permitted by the Loan Documents and releases of the property of and equity in any Subsidiary designated as an Unrestricted Subsidiary in accordance with the definition of such term) without the written consent of each Lender, or (vii) amend this Section 10.1(a) without the written consent of each Lender. Notwithstanding the foregoing or anything to the contrary herein (except Section 2.18, to the extent applicable), Agent shall not, without the prior consent of each individual Lender affected thereby (or, as applicable, an Affiliate of such Lender), execute and deliver any waiver or amendment to any Loan Document which would (i) cause an obligation under any outstanding Hedging Contract owing to such Lender (or its Affiliate) that, prior to such waiver or amendment, constituted a “Lender Hedging Obligation” to cease to be a “Lender Hedging Obligation” or (ii) cause the priority of the Lien securing such obligation or the priority of payment with respect to such obligation in connection with the exercise of remedies under such Loan Document to be subordinate in any manner to the other Secured Obligations (other than expense reimbursements, expenses of enforcement, and other similar obligations owing under the Loan Documents).

(b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Agent or any Lender, whether written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or agreements by any Lender as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender has any fiduciary obligation toward Borrower with respect to any Loan Document or the transactions contemplated thereby, (v) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender, on the other hand, is and shall be solely that of debtor and creditor, respectively; provided that, solely for purposes of Section 10.5(f), Agent shall act as Agent of Borrower in maintaining the Register as set forth therein, (vi) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender, (vii) Agent is not Borrower’s Agent, but Agent for Lenders, provided that, solely for purposes of Section 10.5(f), Agent shall act as Agent of Borrower in maintaining the Register as set forth therein, (viii) should an Event of Default or Default occur or exist, each Lender will determine in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time subject to the terms of this Agreement, (ix) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by any Lender, or any representative thereof, and no such representation or covenant has been made, that any Lender will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such Event of Default or Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the truthfulness of the acknowledgments in this Section in deciding to execute and deliver this Agreement and to become obligated hereunder.

80

(c) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Section 10.2 Survival of Agreements; Cumulative Nature. Except for representations and warranties given as of a specified date, all of Restricted Persons’ various representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans and the delivery of the Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender Party and all of Lender Parties’ obligations to Borrower are terminated. All statements and agreements contained in any certificate or other instrument delivered by any Restricted Person to any Lender Party under any Loan Document shall be deemed representations and warranties by Borrower or agreements and covenants of Borrower under this Agreement. The representations, warranties, indemnities, and covenants made by Restricted Persons in the Loan Documents, and the rights, powers, and privileges granted to Lender Parties in the Loan Documents, are cumulative, and, except for expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to any Lender Party of any such representation, warranty, indemnity, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein contained shall apply to any similar representation, warranty, indemnity, or covenant contained in any other Loan Document, unless the Loan Documents shall expressly provide that such exception shall apply to such similar representation, warranty, indemnity, or covenant.

Section 10.3 Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Agent may give telephonic notices to the other Lender Parties), and shall be deemed sufficiently given or furnished if delivered by personal delivery, by facsimile or other electronic transmission, by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower and Restricted Persons at the address of Borrower specified on the signature pages hereto and to each Lender Party at its address specified on the Lenders Schedule (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address provided herein, (b) in the case of facsimile or other electronic transmission, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail; provided, however, that no Borrowing Notice shall become effective until actually received by Agent.

81

Section 10.4 Payment of Expenses; Indemnity.

(a) Payment of Expenses. Whether or not the transactions contemplated by this Agreement are consummated, Borrower will promptly (and in any event, within thirty (30) days after any invoice or other statement or notice) pay: (i) all transfer, stamp, mortgage, documentary or other similar Taxes, assessments or charges levied by any governmental or revenue authority in respect of this Agreement or any of the other Loan Documents or any other document or transaction referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on behalf of Agent (including without limitation reasonable attorneys’ fees, travel costs and miscellaneous expenses), but excluding consultants fees other than in connection with an annual field audit permitted below, in connection with (1) the negotiation, preparation, execution and delivery of the Loan Documents, and any and all consents, waivers or other documents or instruments relating thereto, (2) the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled or re-recorded by the terms of any Loan Document, (3) the borrowings hereunder and other action reasonably required in the course of administration hereof, (4) monitoring or confirming (or preparation or negotiation of any document related to) any Restricted Person’s compliance with any covenants or conditions contained in this Agreement or in any Loan Document, (iii) all reasonable costs and expenses incurred by Agent on behalf of any Lender Party (including without limitation reasonable attorneys’ fees, reasonable consultants’ fees and reasonable accounting fees) in connection with the conduct of an annual field audit and (iv) all reasonable costs and expenses incurred by Agent and any Lender Party in connection with the enforcement of its rights (A) in connection with this Agreement (including its rights under this Section) or any of the Loan Documents, or (B) in connection with the Loans made or Letters of Credit issued hereunder, including all such reasonable out-of-pocket expenses incurred during any workout, restructuring or negotiations in respect such Loans or Letters of Credit. In addition to the foregoing, until all Obligations have been paid in full, Borrower will also pay or reimburse Agent for all reasonable out-of-pocket costs and expenses of Agent or its agents or employees in connection with the continuing administration of the Loans and the related due diligence of Agent, including travel and miscellaneous expenses and reasonable fees and expenses of Agent’s outside counsel and consultants engaged in connection with the Loan Documents.

(b) Indemnity. Borrower agrees to indemnify each Lender Party, upon demand, from and against any and all liabilities, obligations, broker’s fees, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this Section collectively called “liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Lender Party growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated therein (whether arising in contract or in tort or otherwise). Among other things, the foregoing indemnification covers all liabilities and costs incurred by any Lender Party related to any breach of a Loan Document by a Restricted Person, any bodily injury to any Person or damage to any Person’s property, or any violation or noncompliance with any Environmental Laws by any Lender Party or any other Person or any liabilities or duties of any

82

Lender Party or any other Person with respect to Hazardous Materials found in or released into the environment.

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR CAUSED, IN WHOLE OR IN PART BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY,

provided only that no Lender Party shall be entitled under this Section to receive indemnification for that portion, if any, of any liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined by a court of competent jurisdiction in a final and nonappealable judgment. If any Person (including Borrower or any of its Affiliates) ever alleges such gross negligence or willful misconduct by any Lender Party, the indemnification provided for in this Section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as a court of competent jurisdiction enters a final and nonappealable judgment as to the extent and effect of the alleged gross negligence or willful misconduct. As used in this Section the term “Lender Party” shall refer not only to each Person designated as such in Section 1.1 but also to each director, officer, Agent, trustee, attorney, employee, representative and Affiliate of or for such Person. Notwithstanding anything to the contrary in this Agreement, this Section 10.4 shall not apply with respect to any Taxes aside from those attributable to a non-Tax claim.

Section 10.5 Joint and Several Liability; Parties in Interest; Assignments.

(a) All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations and liabilities. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Restricted Person may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of the Required Lenders. Neither Borrower nor any Affiliates of Borrower shall directly or indirectly purchase or otherwise retire any Obligations owed to any Lender nor will any Lender accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Percentage Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower at any time purchases some but less than all of the Obligations owed to all Lender Parties, such purchaser shall not be entitled to any rights of any Lender under the Loan Documents unless and until Borrower or its Affiliates have purchased all of the Obligations.

(b) No Lender shall sell any participation interest in its commitment hereunder or any of its rights under its Loans or under the Loan Documents to any Person unless the agreement between such Lender and such participant at all times provides: (i) that such participation exists only as a result of the agreement between such participant and such Lender and that such transfer does not give such participant any right to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant is not entitled to payment from any Restricted Person under Sections 3.2 through 3.8 of amounts in excess of those payable to such Lender under such Sections (determined without regard to the sale of such participation),

83

and (iii) unless such participant is an Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any Loan Document, except for actions which would require the consent of all Lenders under subsection (a) of Section 10.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be relieved of any of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Agent and Borrower. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of Borrower, maintain a register on which it enters the name and address of each participant and the principal amounts of (and stated interest on) each participant’s interest in the Loan Documents or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any information relating to a participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

(c) Except for sales of participations under the immediately preceding subsection, no Lender shall make any assignment or transfer of any kind of its commitments or any of its rights under its Loans or under the Loan Documents, except for assignments to an Eligible Transferee, and then only if such assignment is made in accordance with the following requirements:

(i) Each such assignment shall apply to all Obligations owing to the assignor Lender hereunder and to the unused portion of the assignor Lender’s Revolving Loan Commitment, so that after such assignment is made the assignor Lender shall have a fixed (and not a varying) Percentage Share in its Loans and Notes and be committed to make that Percentage Share of all future Loans, the assignee shall have a fixed Percentage Share in the aggregate Loans and Notes and be committed to make that Percentage Share of all future Loans, and, except in the case of an assignment of the entire remaining amount of the assignor’s Percentage Share of the Revolving Loan Commitment, the Revolving Loan Commitment to be assigned shall equal or exceed $5,000,000.

(ii) The parties to each such assignment shall execute and deliver to Agent, for its acceptance and recording in the “Register” (as defined below in subsection (f)), an Assignment and Acceptance in the form of Exhibit 10.5, appropriately completed, together with the Note subject to such assignment and a processing fee payable to Agent of $3,500. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (1) Borrower shall issue new Notes to such assignor and assignee upon return of the old Notes to Borrower, and (2) as of the “Settlement Date” specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Agent shall thereupon

84

deliver to Borrower and each Lender a schedule showing the revised Percentage Shares of such assignor Lender and such assignee Lender and the Percentage Shares of all other Lenders.

(iii) Each assignee Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code) for Federal income Tax purposes, shall (to the extent it has not already done so) provide Agent and Borrower with the “Prescribed Forms” referred to in Section 3.6(d).

(iv) Each such assignment shall require the prior written consent (such consent not to be unreasonably withheld or delayed) of:

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

(B) Agent; provided that no consent of Agent shall be required for an assignment to a Lender, an Affiliate of a Lender or an Approved Fund; and

(C) the LC Issuer and the Swingline Lender.

(d) Nothing contained in this Section shall prevent or prohibit any Lender from assigning or pledging all or any portion of its Loans and Notes to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder.

(e) By executing and delivering an Assignment and Acceptance, each assignee Lender thereunder will be confirming to and agreeing with Borrower, Agent and each other Lender Party that such assignee understands and agrees to the terms hereof, including Article IX hereof.

(f) Agent acting solely for this purpose as a non-fiduciary agent of Borrower, shall maintain a copy of each Assignment and Acceptance and a register for the recordation of the names and addresses of Lenders and the Percentage Shares of, and principal amount of (and stated interest on) the Loans owing to, each Lender from time to time (in this Section called the “Register”). The entries in the Register shall be conclusive, in the absence of manifest error, and Borrower and each Lender Party shall treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes. The Register shall be available for inspection by Borrower or any Lender Party at any reasonable time and from time to time upon reasonable prior notice. Agent shall act as Agent of Borrower solely for purposes of maintaining the Register as set forth in this Section 10.5(f).

(g) Borrower shall not assign or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender (and any attempted assignment or transfer by Borrower without such consent shall be null and void).

85

Section 10.6 Confidentiality. Each Lender Party agrees to keep confidential any information furnished or made available to it by any Restricted Person pursuant to this Agreement that is financial information, information in connection with a proposed transaction, or information marked confidential; provided that nothing herein shall prevent any Lender Party from disclosing such information (a) to any other Lender Party or any Affiliate of any Lender Party, or any officer, director, employee, agent, attorney, auditor, or advisor of any Lender Party or Affiliate of any Lender Party, (b) to any other Person if reasonably incidental to the administration of the credit facility provided herein, (c) as required by any Law, (d) upon the order of any court or administrative agency, (e) upon the request or demand of any Tribunal, (f) that is or becomes available to the public or that is or becomes available to any Lender Party other than as a result of a disclosure by any Lender Party prohibited by this Agreement, (g) to the extent necessary in connection with the exercise of any right or remedy under this Agreement or any other Loan Document, (h) subject to provisions substantially similar to those contained in this Section, to any actual or proposed participant or assignee or any actual or proposed contractual counterparty (or its advisors) to any securitization, hedge, or other derivative transaction relating to the parties’ obligations hereunder, and (i) if it is otherwise available in the public domain. Any Person required to maintain the confidentiality of information described in this Section 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 10.7 Governing Law; Submission to Process. Except to the extent that the Law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under the Laws of the State of Texas and shall be construed and enforced in accordance with and governed by the Laws of the State of Texas and the Laws of the United States of America, without regard to principles of conflicts of law. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party accounts) does not apply to this Agreement or to the Notes. Borrower hereby irrevocably submits itself and each other Restricted Person to the exclusive jurisdiction of the state and federal courts sitting in the State of Texas and agrees and consents that service of process may be made upon it or any Restricted Person in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under Texas or federal law. Any legal proceeding arising out of or in any way related to any of the Loan Documents shall be brought and litigated exclusively in the United States District Court for the Southern District of Texas, Houston Division, to the extent it has subject matter jurisdiction, and otherwise in the Texas District Courts sitting in Harris County, Texas. The parties hereto hereby waive and agree not to assert, by way of motion, as a defense or otherwise, that any such proceeding is brought in an inconvenient forum or that the venue thereof is improper, and further agree to a transfer of any such proceeding to a federal court sitting in the State of Texas to the extent that it has subject matter jurisdiction, and otherwise to a state court in Houston, Texas. In furtherance thereof, Borrower and Lender Parties each hereby acknowledge and agree that it was not inconvenient for them to negotiate and receive funding of the transactions contemplated by this Agreement in such county and that it will be neither inconvenient nor unfair to litigate or otherwise resolve any disputes or claims in a court sitting in such county.

Section 10.8 Limitation on Interest. Lender Parties, Restricted Persons and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury Law

86

from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable Law from time to time in effect. Neither any Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully contracted for, charged, or received under applicable Law from time to time in effect, and the provisions of this Section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Lender Parties expressly disavow any intention to contract for, charge, or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable Law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender’s or holder’s option, promptly returned to Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable Law, Lender Parties and Restricted Persons (and any other payors thereof) shall to the greatest extent permitted under applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable Law in order to lawfully contract for, charge, or receive the maximum amount of interest permitted under applicable Law. In the event applicable Law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the “Texas Finance Code”) as amended, for that day, the ceiling shall be the “weekly ceiling” as defined in the Texas Finance Code, provided that if any applicable Law permits greater interest, the Law permitting the greatest interest shall apply. As used in this Section the term “applicable Law” means the Laws of the State of Texas or the Laws of the United States of America, whichever Laws allow the greater interest, as such Laws now exist or may be changed or amended or come into effect in the future.

Section 10.9 Termination; Limited Survival; Releases of Liens and Guaranties.

(a) In its sole and absolute discretion Borrower may at any time that no Obligations are owing (other than indemnity obligations and similar obligations that survive the termination of this Agreement for which no notice of a claim has been received by Borrower) elect in a written notice delivered to Agent to terminate this Agreement. Upon receipt by Agent of such a notice, if no Obligations are then owing, this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or

87

admissions made by any Restricted Person in any Loan Document, any Obligations under Sections 3.2 through Section 3.6, and any obligations which any Person may have to indemnify or reimburse any Lender Party shall survive any termination of this Agreement or any other Loan Document. The foregoing consent shall constitute the written consent of Required Lenders required under Section 10.1(a)(iii). At the request and expense of Borrower, Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender.

(b) Agent and the Lenders hereby consent to (i) the automatic release of any Liens securing the Obligations in Collateral that is sold or otherwise disposed of by a Restricted Person in compliance with this Agreement and (ii) the automatic release from the relevant Guaranty of any Guarantor that ceases to be a Subsidiary pursuant to a sale or disposal of property that is permitted by this Agreement, in each case without need for further approval of Agent or any Lender. The foregoing consent shall constitute the written consent of Required Lenders required under the fourth sentence of Section 10.1(a), with respect to such releases of Liens and Guarantors. At the request and expense of Borrower, Agent shall prepare and execute all necessary or reasonably requested instruments and documents to reflect and effect such releases of Liens and Guarantors. Agent is hereby authorized to execute all such instruments and documents on behalf of all Lenders, without the joinder of or further action by any Lender.

Section 10.10 Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable Law.

Section 10.11 Counterparts; Fax. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. This Agreement and the Loan Documents may be validly executed and delivered by facsimile or other electronic transmission.

Section 10.12 Intentionally Omitted.

Section 10.13 Waiver of Jury Trial, Punitive Damages, etc. Each of Borrower and each Lender Party hereby knowingly, voluntarily, intentionally, and irrevocably (a) waives, to the maximum extent not prohibited by Law, any right it may have to a trial by jury in respect of any litigation based hereon, or directly or indirectly at any time arising out of, under or in connection with the Loan Documents or any transaction contemplated thereby or associated therewith, before or after maturity; (b) waives, to the maximum extent not prohibited by Law, any right they may have to claim or recover in any such litigation any “Special Damages”, as defined below, (c) certifies that no party hereto nor any representative or Agent or counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to enforce the foregoing waivers, and (d) acknowledges that it has been induced to enter into this Agreement, the other Loan Documents and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications contained in this Section. As used in this Section, “Special Damages” includes all special,

88

consequential, exemplary, or punitive damages (regardless of how named), but does not include any payments or funds which any party hereto has expressly promised to pay or deliver to any other party hereto.

Section 10.14 USA PATRIOT Act. Agent hereby notifies Borrower that pursuant to the requirements of the PATRIOT Act, and Agent’s policies and practices, each Lender is required to obtain, verify and record certain information and documentation that identifies each Restricted Person, which information includes the name and address of each Restricted Person and such other information that will allow each Lender to identify each Restricted Person in accordance with the PATRIOT Act.

Section 10.15 Renewal and Extension. The Indebtedness arising under this Agreement is a renewal, extension and restatement on revised terms of (but not an extinguishment or novation of) the Existing Credit Agreement and, from and after the date hereof, the terms and provisions of the Existing Credit Agreement shall be superseded by the terms and provisions of this Agreement. Borrower hereby agrees that (a) the Indebtedness evidenced by the Existing Credit Agreement, all accrued and unpaid interest thereon, and all accrued and unpaid fees under the Existing Credit Agreement shall be deemed to be Indebtedness of Borrower outstanding under and governed by this Agreement and (b) all Liens securing the Indebtedness evidenced by the Existing Credit Agreement shall continue in full force and effect to secure the Secured Obligations.

Section 10.16 Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any liability of any EEA Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the Write-Down and Conversion Powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a) the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(b) the effects of any Bail-in Action on any such liability, including, if applicable:

(i) a reduction in full or in part or cancellation of any such liability;

(ii) a conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

(iii) the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of any EEA Resolution Authority.

Section 10.17 Certain ERISA Matters.

89

(a) Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, Agent, the Arranger and their respective Affiliates, and not, for the avoidance of doubt, to or for the benefit of Borrower or any other Restricted Person, that at least one of the following is and will be true:

To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Hedging Contracts or any other agreement or instrument that is a QFC (such support, “QFC Credit Support” and, each such QFC, a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the FDIC under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States):

(a) In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.

(b) As used in this Section 10.18, the following terms have the following meanings:
