Section 2.2 Letters of Credit

(a) Commitment for Letters of Credit. The Issuing Lender, the Lenders and the Borrower agree that effective as of the Effective Date, the Existing Letters of Credit shall be deemed to have been issued and maintained under, and to be governed by the terms and conditions of, this Agreement. Subject to the terms and conditions set forth in this Agreement, the Issuing Lender agrees, in reliance upon the agreements of the other Lenders set forth in this Section 2.2, from time to time on any Business Day during the period from the Effective Date until the Revolving Maturity Date, to issue, increase or extend the expiration date of, Letters of Credit for the account of any Credit Party, provided that no Letter of Credit will be issued, increased, or extended:

(i) if such issuance, increase, or extension would cause the Letter of Credit Exposure to exceed the lesser of (A) the Letter of Credit Maximum Amount and (B) an amount equal to (1) the lesser of the Borrowing Base and the aggregate Revolving Commitments, in either case, in effect at such time minus (2) the sum of the aggregate outstanding amount of all Revolving Advances plus the Letter of Credit Exposure plus the aggregate outstanding amount of all Swing Line Advances;

(ii) unless such Letter of Credit has an expiration date not later than 10 days prior to the Revolving Maturity Date; provided that, if Revolving Commitments are terminated in whole pursuant to Section 2.1(c)(i), any Letter of Credit may have an expiration date after then resulting Revolving Maturity Date if (A) the Borrower shall deposit into the Cash Collateral Account cash in an amount equal to 105% of the Letter of Credit Exposure for the Letters of Credit which have an expiry date beyond the Revolving Maturity Date or (B) the Borrower shall provide a replacement letter of credit (or other security) reasonably acceptable to the Administrative Agent and the Issuing Lender in an amount equal to 105% of the Letter of Credit Exposure;

-25-

(iii) unless such Letter of Credit is a standby letter of credit not supporting the repayment of indebtedness for borrowed money of any Person;

(iv) unless such Letter of Credit is in form and substance acceptable to the Issuing Lender in its sole discretion;

(v) unless the Borrower has delivered to the Issuing Lender a completed and executed Letter of Credit Application; provided that, if the terms of any Letter of Credit Application conflicts with the terms of this Agreement, the terms of this Agreement shall control; and

(vi) unless such Letter of Credit is governed by (A) the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, or (B) the International Standby Practices (ISP98), International Chamber of Commerce Publication No. 590, in either case, including any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Lender.

(b) Requesting Letters of Credit. Each Letter of Credit shall be issued pursuant to a Letter of Credit Application given by the Borrower to the Administrative Agent for the benefit of the Issuing Lender by facsimile or other writing not later than 11:00 a.m. (Houston, Texas, time) on the third Business Day before the proposed date of issuance for the Letter of Credit. Each Letter of Credit Application shall be fully completed and shall specify the information required therein. Each Letter of Credit Application shall be irrevocable and binding on the Borrower. Subject to the terms and conditions hereof, the Issuing Lender shall before 2:00 p.m. (Houston, Texas, time) on the date of such Letter of Credit issue such Letter of Credit to the beneficiary of such Letter of Credit.

(i) With respect to any Letter of Credit, in accordance with the related Letter of Credit Application, the Borrower agrees to pay on demand to the Administrative Agent on behalf of the Issuing Lender an amount equal to any amount paid by the Issuing Lender under such Letter of Credit. Upon the Issuing Lender’s demand for payment under the terms of a Letter of Credit Application, the Borrower may, with a written notice, request that the Borrower’s obligations to the Issuing Lender thereunder be satisfied with the proceeds of a Revolving Advance in the same amount (notwithstanding any minimum size or increment limitations on individual Revolving Advances). If the Borrower does not make such request and does not otherwise make the payments demanded by the Issuing Lender as required under this Agreement or the Letter of Credit Application, then the Borrower shall be deemed for all purposes of this Agreement to have requested such a Revolving Advance in the same amount and the transfer of the proceeds thereof to satisfy the Borrower’s obligations to the Issuing Lender, and the Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Lenders to make such Revolving Advance, to transfer the proceeds thereof to the Issuing Lender in satisfaction of such obligations, and to record and otherwise treat such payments as a Revolving Advance to the Borrower. The Administrative Agent and each

-26-

Lender may record and otherwise treat the making of such Revolving Borrowings as the making of a Revolving Borrowing to the Borrower under this Agreement as if requested by the Borrower. Nothing herein is intended to release any of the Borrower’s obligations under any Letter of Credit Application, but only to provide an additional method of payment therefor. The making of any Borrowing under this Section 2.2(c) shall not constitute a cure or waiver of any Default, other than the payment Default which is satisfied by the application of the amounts deemed advanced hereunder, caused by the Borrower’s failure to comply with the provisions of this Agreement or the Letter of Credit Application.

(ii) Each Lender (including the Lender acting as Issuing Lender) shall, upon notice from the Administrative Agent that the Borrower has requested or is deemed to have requested a Revolving Advance pursuant to Section 2.4 and regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.4, or (C) a Default exists, make funds available to the Administrative Agent for the account of the Issuing Lender in an amount equal to such Lender’s Revolving Pro Rata Share of the amount of such Revolving Advance not later than 1:00 p.m. on the Business Day specified in such notice by the Administrative Agent, whereupon each Lender that so makes funds available shall be deemed to have made a Revolving Advance to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Issuing Lender.

(iii) If any such Lender shall not have so made its Revolving Advance available to the Administrative Agent pursuant to this Section 2.2, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Federal Funds Rate for such day for the first three days and thereafter the interest rate applicable to the Revolving Advance and (B) the Maximum Rate. Whenever, at any time after the Administrative Agent has received from any Lender such Lender’s Revolving Advance, the Administrative Agent receives any payment on account thereof, the Administrative Agent will pay to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Revolving Advance was outstanding and funded), which payment shall be subject to repayment by such Lender if such payment received by the Administrative Agent is required to be returned. Each Lender’s obligation to make the Revolving Advance pursuant to this Section 2.2 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other right which such Lender or any other Person may have against the Issuing Lender, the Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Commitments; (3) any breach of this Agreement by the Borrower or any other Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

(d) Participations. Upon the date of the issuance or increase of a Letter of Credit or the deemed issuance of the Existing Letters of Credit under Section 2.2(a), the Issuing Lender shall be deemed to have sold to each other Lender and each other Lender shall have been deemed to have purchased from the Issuing Lender a participation in the related Letter of Credit

-27-

Obligations equal to such Lender’s Revolving Pro Rata Share at such date and such sale and purchase shall otherwise be in accordance with the terms of this Agreement. The Issuing Lender shall promptly notify each such participant Lender by telex, telephone, or telecopy of each Letter of Credit issued or increased and the actual dollar amount of such Lender’s participation in such Letter of Credit.

(e) Obligations Unconditional. The obligations of the Borrower under this Agreement in respect of each Letter of Credit shall be unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances, notwithstanding the following circumstances:

(i) any lack of validity or enforceability of any Letter of Credit Documents;

(ii) any amendment or waiver of or any consent to departure from any Letter of Credit Documents;

(iii) the existence of any claim, set-off, defense or other right which any Credit Party may have at any time against any beneficiary or transferee of such Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the Issuing Lender, any Lender or any other person or entity, whether in connection with this Agreement, the transactions contemplated in this Agreement or in any Letter of Credit Documents or any unrelated transaction;

(iv) any statement or any 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 to the extent the Issuing Lender would not be liable therefor pursuant to the following paragraph (g);

(v) payment by the Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not comply with the terms of such Letter of Credit; or

(vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing;

provided, however, that nothing contained in this paragraph (e) shall be deemed to constitute a waiver of any remedies of the Borrower in connection with the Letters of Credit.

(f) Prepayments of Letters of Credit. In the event that any Letter of Credit shall be outstanding or shall be drawn and not reimbursed on or prior to the 10^th day prior to the Revolving Maturity Date, the Borrower shall pay to the Administrative Agent an amount equal to 105% of the Letter of Credit Exposure allocable to such Letter of Credit, such amount to be due and payable on the 10^th day prior to the Revolving Maturity Date, and to be held in the Cash Collateral Account and applied in accordance with paragraph (i) below.

(g) Liability of Issuing Lender. The Borrower assumes all risks of the acts or omissions of any beneficiary or transferee of any Letter of Credit with respect to its use of such Letter of Credit. Neither the Issuing Lender nor any of its officers or directors shall be liable or responsible for:

(i) the use which may be made of any Letter of Credit or any acts or omissions of any beneficiary or transferee in connection therewith;

-28-

(ii) the validity, sufficiency or genuineness of documents, or of any endorsement thereon, even if such documents should prove to be in any or all respects invalid, insufficient, fraudulent or forged;

(iii) payment by the Issuing Lender against presentation of documents which do not comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

(iv) any other circumstances whatsoever in making or failing to make payment under any Letter of Credit (INCLUDING THE ISSUING LENDER’S OWN NEGLIGENCE),

except that the Borrower shall have a claim against the Issuing Lender, and the Issuing Lender shall be liable to, and shall promptly pay to, the Borrower, to the extent of any direct, as opposed to consequential, damages suffered by the Borrower which the Borrower proves were caused by (A) the Issuing Lender’s willful misconduct or gross negligence in determining whether documents presented under a Letter of Credit comply with the terms of such Letter of Credit or (B) the Issuing Lender’s willful failure to make lawful payment under any Letter of Credit after the presentation to it of a draft and certificate strictly complying with the terms and conditions of such Letter of Credit. In furtherance and not in limitation of the foregoing, the Issuing Lender may accept documents that appear on their face to be in order, without responsibility for further investigation, regardless of any notice or information to the contrary.

(h) Cash Collateral Account.

(i) If the Borrower is required to deposit funds in the Cash Collateral Account pursuant to Sections 2.2(f), 2.5(c), 7.2(b) or 7.3(b), then the Borrower and the Administrative Agent shall establish the Cash Collateral Account and the Borrower shall execute any documents and agreements, including the Administrative Agent’s standard form assignment of deposit accounts, that the Administrative Agent requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent an Acceptable Security Interest in such account and the funds therein. The Borrower hereby pledges to the Administrative Agent and grants the Administrative Agent a security interest in the Cash Collateral Account, whenever established, all funds held in the Cash Collateral Account from time to time, and all proceeds thereof as security for the payment of the Secured Obligations.

(ii) Funds held in the Cash Collateral Account shall be held as cash collateral for obligations with respect to Letters of Credit and promptly applied by the Administrative Agent at the request of the Issuing Lender to any reimbursement or other obligations under Letters of Credit that exist or occur. To the extent that any surplus funds are held in the Cash Collateral Account above the Letter of Credit Exposure during

-29-

the existence of an Event of Default the Administrative Agent may (A) hold such surplus funds in the Cash Collateral Account as cash collateral for the Secured Obligations or (B) apply such surplus funds to any Secured Obligations in any manner directed by the Majority Lenders. If no Default exists, the Administrative Agent shall release to the Borrower at the Borrower’s written request any funds held in the Cash Collateral Account above the amounts required by Section 2.2(f).

(iii) Funds held in the Cash Collateral Account shall be invested in Liquid Investments maintained with, and under the sole dominion and control of, the Administrative Agent or in another investment if mutually agreed upon by the Borrower and the Administrative Agent, but the Administrative Agent shall have no other obligation to make any other investment of the funds therein. The Administrative Agent shall exercise reasonable care in the custody and preservation of any funds held in the Cash Collateral Account and shall be deemed to have exercised such care if such funds are accorded treatment substantially equivalent to that which the Administrative Agent accords its own property, it being understood that the Administrative Agent shall not have any responsibility for taking any necessary steps to preserve rights against any parties with respect to any such funds.

(i) Letters of Credit Issued for Guarantors. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Guarantor or any Subsidiary, the Borrower shall be obligated to reimburse the Issuing Lender hereunder for any and all drawings under such Letter of Credit issued hereunder by the Issuing Lender. The Borrower hereby acknowledges that the issuance of Letters of Credit for the account of any Guarantor, the Borrower or any Subsidiary inures to the benefit of the Borrower, and that the Borrower’s business (indirectly or directly) derives substantial benefits from the businesses of such other Persons.

Section 2.3 Swing Line Advances.

(a) Commitment. On the terms and conditions set forth in this Agreement, and if an AutoBorrow Agreement is in effect, subject to the terms and conditions of such AutoBorrow Agreement, the Swing Line Lender agrees to from time-to-time on any Business Day during the period from the date of this Agreement until the last Business Day occurring before the Revolving Maturity Date, make Swing Line Advances under the Swing Line Note to the Borrower which shall be due and payable on the Swing Line Payment Date (except that no Swing Line Advance may mature after the Revolving Maturity Date), bearing interest at the Adjusted Base Rate plus the Applicable Margin for Base Rate Advances, and in an aggregate principal amount not to exceed the Swing Line Commitment outstanding at any time; provided that (i) after giving effect to such Swing Line Advance, the sum of the aggregate outstanding amount of all Revolving Advances plus the Letter of Credit Exposure plus the aggregate outstanding amount of all Swing Line Advances, shall not exceed the aggregate Revolving Commitments in effect at such time; (ii) no Swing Line Advance shall be made by the Swing Line Lender if the conditions set forth in Section 3.2 have not been met as of the date of such Swing

-30-

Line Advance, it being agreed by the Borrower that the giving of the applicable Notice of Borrowing and the acceptance by the Borrower of the proceeds of such Swing Line Advance shall constitute a representation and warranty by the Borrower that on the date of such Swing Line Advance such conditions have been met; (iii) each Swing Line Advance shall be in an aggregate amount not less than $250,000.00 and in integral multiples of $50,000.00 in excess thereof; and (iv) if an AutoBorrow Agreement is in effect, such additional terms and conditions of such AutoBorrow Agreement shall have been satisfied. The indebtedness of the Borrower to the Swing Line Lender resulting from Swing Line Advances shall be evidenced by the Swing Line Note. No Lender shall have any rights or obligations under any AutoBorrow Agreement, but each Lender shall have the obligation to purchase and fund risk participations in the Swing Line Advances and to refinance Swing Line Advances as provided below.

(b) Prepayment. Within the limits expressed in this Agreement, amounts advanced pursuant to Section 2.3(a) may from time to time be borrowed, prepaid without penalty, and reborrowed. If the aggregate outstanding principal amount of the Swing Line Advances ever exceeds the Swing Line Commitment, the Borrower shall, upon receipt of written notice of such condition from the Swing Line Lender and to the extent of such excess, prepay to the Swing Line Lender outstanding principal of the Swing Line Advances such that such excess is eliminated. If an AutoBorrow Agreement is in effect, each prepayment of a Swing Line Borrowing shall be made as provided in such AutoBorrow Agreement.

(i) With respect to the Swing Line Advances and the interest, premium, fees, and other amounts owed by the Borrower to the Swing Line Lender in connection with the Swing Line Advances, the Borrower agrees to pay to the Swing Line Lender such amounts when due and payable to the Swing Line Lender under the terms of this Agreement and, if an AutoBorrow Agreement is in effect, in accordance with the terms of such AutoBorrow Agreement. If the Borrower does not pay to the Swing Line Lender any such amounts when due and payable to the Swing Line Lender, the Swing Line Lender may upon notice to the Administrative Agent request the satisfaction of such obligation by the making of a Revolving Borrowing in the amount of any such amounts not paid when due and payable. Upon such request, the Borrower shall be deemed to have requested the making of a Revolving Borrowing in the amount of such obligation and the transfer of the proceeds thereof to the Swing Line Lender. Such Revolving Borrowing shall bear interest based upon the Adjusted Base Rate plus the Applicable Margin for Base Rate Advances. The Administrative Agent shall promptly forward notice of such Revolving Borrowing to the Borrower and the Lenders, and each Lender shall, regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.4, or (C) a Default exists, make available such Lender’s ratable share of such Revolving Borrowing to the Administrative Agent, and the Administrative Agent shall promptly deliver the proceeds thereof to the Swing Line Lender for application to such amounts owed to the Swing Line Lender. The Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Swing Line Lender to make such requests for Revolving Borrowings on behalf of the Borrower, and the Lenders to make Revolving Advances to the Administrative Agent for the benefit of the Swing Line Lender in satisfaction of such obligations. The Administrative Agent and each Lender may record and otherwise treat the making of such Revolving Borrowings as the making of a Revolving Borrowing to the Borrower under this Agreement as if requested by the Borrower. Nothing herein is intended to release the Borrower’s

-31-

obligations under the Swing Line Note, but only to provide an additional method of payment therefor. The making of any Borrowing under this Section 2.3(c) shall not constitute a cure or waiver of any Default or Event of Default, other than the payment Default or Event of Default which is satisfied by the application of the amounts deemed advanced hereunder, caused by the Borrower’s failure to comply with the provisions of this Agreement or the Swing Line Note.

(ii) If at any time, the Revolving Commitments shall have expired or be terminated while any Swing Line Advance is outstanding, each Lender, at the sole option of the Swing Line Lender, shall either (A) notwithstanding the expiration or termination of the Revolving Commitments, make a Revolving Advance as a Base Rate Advance, or (B) be deemed, without further action by any Person, to have purchased from the Swing Line Lender a participation in such Swing Line Advance, in either case in an amount equal to the product of such Lender’s Revolving Pro Rata Share times the outstanding aggregate principal balance of the Swing Line Advances. The Administrative Agent shall notify each such Lender of the amount of such Revolving Advance or participation, and such Lender will transfer to the Administrative Agent for the account of the Swing Line Lender on the next Business Day following such notice, in immediately available funds, the amount of such Revolving Advance or participation.

(iii) If any such Lender shall not have so made its Revolving Advance or its percentage participation available to the Administrative Agent pursuant to this Section 2.3, such Lender agrees to pay interest thereon for each day from such date until the date such amount is paid at the lesser of (A) the Federal Funds Rate for such day for the first three days and thereafter the interest rate applicable to the Revolving Advance and (B) the Maximum Rate. Whenever, at any time after the Administrative Agent has received from any Lender such Lender’s Revolving Advance or participating interest in a Swing Line Advance, the Administrative Agent receives any payment on account thereof, the Administrative Agent will pay to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s Revolving Advance or participating interest was outstanding and funded), which payment shall be subject to repayment by such Lender if such payment received by the Administrative Agent is required to be returned. Each Lender’s obligation to make the Revolving Advance or purchase such participating interests pursuant to this Section 2.3 shall be absolute and unconditional and shall not be affected by any circumstance, including (1) any set-off, counterclaim, recoupment, defense or other right which such Lender or any other Person may have against the Swing Line Lender, the Administrative Agent or any other Person for any reason whatsoever; (2) the occurrence or continuance of a Default or the termination of the Commitments; (3) any breach of this Agreement by the Borrower or any other Lender; or (4) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. Each Swing Line Advance, once so participated by any Lender, shall cease to be a Swing Line Advance with respect to that amount for purposes of this Agreement, but shall continue to be a Revolving Loan.

(d) Method of Borrowing. If an AutoBorrow Agreement is in effect, each Swing Line Borrowing shall be made as provided in such AutoBorrow Agreement. Otherwise, and

-32-

except as provided in the clause (c) above, each request for a Swing Line Advance shall be made pursuant to telephone notice to the Swing Line Lender given no later than 1:00 p.m. (Houston, Texas time) on the date of the proposed Swing Line Advance, promptly confirmed by a completed and executed Notice of Borrowing telecopied or facsimiled to the Administrative Agent and the Swing Line Lender. The Swing Line Lender will promptly make the Swing Line Advance available to the Borrower at the Borrower’s account with the Administrative Agent.

(e) Interest for Account of Swing Line Lender. Swing Line Lender shall be responsible for invoicing the Borrower for interest on the Swing Line Advances (provided that any failure of the Swing Line Lender to provide such invoice shall not release the Borrower from its obligation to pay such interest). Until each Lender funds its Revolving Advance or risk participation pursuant to clause (c) above, interest in respect of Lender’s Pro Rata Share of the Swing Line Advances shall be solely for the account of the Swing Line Lender.

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

(g) Termination of Swing Line Sublimit. Swing Line Lender may terminate and/or suspend its Swing Line Commitment in accordance with any applicable AutoBorrow Agreement.

Section 2.4 Advances.

(a) Notice.

(provided that for Eurodollar Advances with six month Interest Periods, accrued but unpaid interest shall also be due on the day three months from the first day of such Interest Period), on the date any Eurodollar Advance is repaid in full, and on the Revolving Maturity Date or the Term Maturity Date, as applicable.

(c) Additional Interest on Eurodollar Advances. The Borrower shall pay to the Administrative Agent for the ratable account of each Lender so long as such Lender shall be required under regulations of the Federal Reserve Board applicable to all Lenders regulated by the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Advance of such Lender, from the date such requirement is imposed until the earlier of (i) the date such requirement is no longer imposed and (ii) the date on which such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (A) the Eurodollar Rate for the Interest Period for such Eurodollar Advance from (B) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance.

(d) Retroactive Adjustments of Applicable Margin. In the event that any financial statement or Compliance Certificate delivered pursuant to Section 5.2 is shown to be inaccurate (regardless of whether this Agreement or the Commitments are in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Margin for any period (an “Applicable Period”) than the Applicable Margin applied for such Applicable Period, then (i) the Borrower shall immediately deliver to the Administrative Agent a corrected Compliance Certificate for such Applicable Period, (ii) the Applicable Margin shall be determined as if the higher Applicable Margin that would have applied were applicable for such Applicable Period (and in any event at Level 6 if the inaccuracy was the result of dishonesty, fraud or willful misconduct), and (iii) the Borrower shall immediately, without further action by the Administrative Agent, any Lender or the Issuing Lender, pay to the Administrative Agent for the account of the applicable Lenders, the accrued additional interest owing as a result of such increased Applicable Margin for such Applicable Period.

Section 2.9 Illegality. If any Lender shall notify the Borrower that the introduction of or any change in or in the interpretation of any law or regulation makes it unlawful, or that any central bank or other governmental authority asserts that it is unlawful, for such Lender or its Applicable Lending Office to perform its obligations under this Agreement to make, maintain, or fund any Eurodollar Advances of such Lender then outstanding hereunder, (a) the Borrower shall, no later than 11:00 a.m. (Houston, Texas, time) (i) if not prohibited by law, on the last day

-40-

of the Interest Period for each outstanding Eurodollar Advance or (ii) if required by such notice, on the second Business Day following its receipt of such notice, prepay all of the Eurodollar Advances of such Lender then outstanding, together with accrued interest on the principal amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.10 as a result of such prepayment being made on such date, (b) such Lender shall simultaneously make a Base Rate Advance to the Borrower on such date in an amount equal to the aggregate principal amount of the Eurodollar Advances prepaid to such Lender, and (c) the right of the Borrower to select Eurodollar Advances from such Lender for any subsequent Borrowing shall be suspended until such Lender shall notify the Borrower that the circumstances causing such suspension no longer exist. Each Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different Applicable Lending Office if the making of such designation would avoid the effect of this paragraph and would not, in the reasonable judgment of such Lender, be otherwise disadvantageous to such Lender.

Section 2.10 Breakage Costs.

(a) Funding Losses. In the case of any Revolving Borrowing which the related Notice of Borrowing specifies is to be comprised of Eurodollar Advances, the Borrower shall indemnify each Lender against any loss, out-of-pocket cost, or expense incurred by such Lender as a result of any failure to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article 3, including, without limitation, any loss (excluding any loss of anticipated profits), cost, or expense incurred by reason of the liquidation or redeployment of deposits or other funds acquired by such Lender to fund the Eurodollar Advance to be made by such Lender as part of such Borrowing when such Eurodollar Advance, as a result of such failure, is not made on such date.

(b) Prepayment Losses. If (i) any payment of principal of any Eurodollar Advance is made other than on the last day of the Interest Period for such Advance as a result of any prepayment, payment pursuant to Section 2.9, the acceleration of the maturity of the Notes, or for any other reason or (ii) the Borrower fails to make a principal or interest payment with respect to any Eurodollar Advance on the date such payment is due and payable, the Borrower shall, within 10 days of any written demand sent by the Administrative Agent on behalf of a Lender to the Borrower, pay to the Administrative Agent for the benefit of such Lender any amounts determined in good faith by such Lender to be required to compensate such Lender for any additional losses, out-of-pocket costs, or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss (excluding loss of anticipated profits), cost, or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

Section 2.11 Increased Costs.

(a) Eurodollar Advances. If, after the Effective Date, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by financial institutions generally, including a Lender (or its Applicable Lending Office) with any request or directive (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency:

(i) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement (other than by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, financial institutions generally, including such Lender (or its Applicable Lending Office), including the Commitments of such Lender hereunder; or

-41-

(ii) shall impose on financial institutions generally, including such Lender (or its Applicable Lending Office), or on the London interbank market any other condition affecting this Agreement or its Notes or any of such extensions of credit or liabilities or commitments;

and the result of any of the foregoing is to increase the cost to such Lender (or its Applicable Lending Office) of making, Converting into, continuing, or maintaining any Eurodollar Advances or to reduce any sum received or receivable by such Lender (or its Applicable Lending Office) under this Agreement or its Notes with respect to any Eurodollar Advances, then the Borrower shall pay to such Lender within three Business Days after written demand made by such Lender such amount or amounts as such Lender determines in good faith to be necessary to compensate such Lender for such increased cost or reduction.

(b) Capital Adequacy. If, after the Effective Date, any Lender or the Issuing Lender shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of financial institutions generally, including such Lender or the Issuing Lender or any corporation controlling such Lender or the Issuing Lender, as a consequence of such Lender’s or the Issuing Lender’s obligations hereunder to a level below that which such Lender or the Issuing Lender or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from time to time within three Business Days after written demand by such Lender or the Issuing Lender, as the case may be, the Borrower shall pay to such Lender or the Issuing Lender such additional amount or amounts as such Lender determines in good faith to be necessary to compensate such Lender or the Issuing Lender for such reduction.

(c) Mitigation. Each Lender shall promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the Effective Date, which will entitle such Lender to compensation pursuant to this Section 2.11 and will designate a different Applicable Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the reasonable judgment of such Lender, be otherwise disadvantageous to it. Any Lender claiming compensation under this Section 2.11 shall furnish to the Borrower and the Administrative Agent a statement setting forth the

-42-

additional amount or amounts to be paid to it hereunder which shall be determined by such Lender in good faith and which shall be conclusive in the absence of manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods.

Section 2.12 Payments and Computations.

(a) Payments. All payments of principal, interest, and other amounts to be made by the Borrower under this Agreement and other Credit Documents shall be made to the Administrative Agent in Dollars and in immediately available funds, without setoff, deduction, or counterclaim.

(b) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes not later than 11:00 a.m. (Houston, Texas time) on the day when due in Dollars to the Administrative Agent at the location referred to in the Notes (or such other location as the Administrative Agent shall designate in writing to the Borrower) in same day funds. The Administrative Agent will promptly thereafter, and in any event prior to the close of business on the day any timely payment is made, cause to be distributed like funds relating to the payment of principal, interest or fees ratably (other than amounts payable solely to the Administrative Agent or a specific Lender pursuant to Sections 2.8(c), 2.9, 2.10, 2.11, 2.13, and 9.2 but after taking into account payments effected pursuant to Section 9.1) in accordance with each Lender’s applicable pro rata share to the Lenders for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Lender to such Lender for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. Upon receipt of other amounts due solely to the Administrative Agent, the Issuing Lender, the Swing Line Lender, or a specific Lender, the Administrative Agent shall distribute such amounts to the appropriate party to be applied in accordance with the terms of this Agreement.

(c) Non-Business Day Payments. Whenever any payment shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or fees, as the case may be; provided that if such extension would cause payment of interest on or principal of Eurodollar Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(d) Computations. All computations of interest and fees shall be made by the Administrative Agent on the basis of a year of 365/366 days for Base Rate Advances and a year of 360 days for all other interest and fees, in each case for the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest or fees are payable. Each determination by the Administrative Agent of an amount of interest or fees shall be conclusive and binding for all purposes, absent manifest error.

(e) Sharing of Payments, Etc. If any Lender shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of set-off, or otherwise) on account of the Advances made by it in excess of its ratable share of payments on account of the Advances or Letter of Credit Obligations obtained by the Lenders, such Lender shall notify the other Lenders

-43-

and forthwith purchase from the other Lenders such participations in the Advances made by it or the Letter of Credit Obligations held by it as shall be necessary to cause such purchasing Lender to share the excess payment ratably with the other Lenders; provided that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from the other Lenders shall be rescinded and each such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share, but without interest. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.12(e) may, to the fullest extent permitted by law, exercise all its rights of payment (including the right of set-off) with respect to such participation as fully as if such Lender were the direct creditor of the Borrower in the amount of such participation.

Section 2.13 Taxes.

(a) No Deduction for Certain Taxes. Any and all payments by the Borrower under any of the Credit Documents to the Administrative Agent, the Issuing Lender, or a Lender shall be made, in accordance with Section 2.12, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges, or withholdings, and all liabilities with respect thereto, excluding, in the case of the Administrative Agent, the Issuing Lender, or a Lender, (i) taxes imposed on its income and franchise or similar taxes imposed on it by the jurisdiction (or any political subdivision thereof) under the laws of which (or under the laws of a political subdivision of which) (A) the Administrative Agent, the Issuing Lender, or such Lender is organized or in which its principal executive office is located or (B) in the case of each Lender, such Lender’s Applicable Lending Office is located and (ii) any taxes imposed by the United States of America by means of withholding at the source, if and to the extent such United States withholding taxes are in effect on the date a Lender becomes a Lender hereunder (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to as “Taxes”). Except as provided in Section 2.13(f), if the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to the Administrative Agent, the Issuing Lender, or any Lender, (i) the sum payable shall be increased as may be necessary so that, after making all required deductions (including deductions applicable to additional sums payable under this Section 2.13), such Lender receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower shall make such deductions; and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority or other authority in accordance with applicable law.

(b) Other Taxes. In addition, except as provided in Section 2.13(f), the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges, or similar levies which arise from any payment made under any Credit Document or from the execution, delivery, or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Credit Documents (hereinafter referred to as “Other Taxes”).

(c) Indemnification. EXCEPT AS PROVIDED IN SECTION 2.13(F), THE BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER, AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED ON AMOUNTS PAYABLE UNDER THIS SECTION 2.13) PAID BY SUCH LENDER, THE ISSUING LENDER, OR THE ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND

-44-

ANY LIABILITY (INCLUDING INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED.

(d) Evidence of Tax Payments. As soon as practicable after any payment of Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of any receipt issued by such Governmental Authority evidencing such payment.

(e) Foreign Lender Withholding Exemption. Each Lender that is not incorporated under the laws of the United States of America or a state thereof and that is entitled to an exemption from United States withholding tax with respect to payments under this Agreement under applicable law or any treaty to which the United States is a party shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation (including Internal Revenue Service Forms W-8BEN or W-8ECI) prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding.

(f) Failure to Provide Forms. For any period with respect to which a Lender has failed to provide the Borrower or the Administrative Agent with the appropriate forms referred to in this Section 2.13 (unless such failure is due to a change in treaty, law or regulation occurring after the date on which such Lender becomes a Lender hereunder), such Lender shall not be entitled to indemnification or payment under the Section 2.13(a), (b), or (c) with respect to Taxes imposed by the United States; provided that if a Lender, that is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to Taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request, and at the expenses of such Lender, to assist such Lender to recover such Taxes.

(g) Mitigation. Each Lender shall use reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to select a jurisdiction for its Applicable Lending Office or change the jurisdiction of its Applicable Lending Office, as the case may be, so as to avoid the imposition of any Taxes or Other Taxes or to eliminate or reduce the payment of any additional sums under this Section 2.13; provided, that no such selection or change of jurisdiction for its Applicable Lending Office shall be made if, in the reasonable judgment of such Lender, such selection or change would be disadvantageous to such Lender.

(h) Tax Credits and Refunds. If the Administrative Agent, the Issuing Lender, or a Lender has determined that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional sums pursuant to this Section 2.13, or if the Administrative Agent or a Lender has determined that it received a credit from any Governmental Authority to which the Administrative Agent or such Lender would not be entitled but for the payment by the Borrower of Taxes, Other Taxes or additional sums pursuant to this Section 2.13, at the Borrower’s request it shall pay over the amount of such refund or credit to the Borrower (but only to the extent of indemnity payments made, or additional sums paid, by the Borrower under this Section 2.13 with respect to the Taxes or Other Taxes giving rise to such refund or credit), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the

-45-

relevant Governmental Authority with respect to such refund or credit); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event and to the extent that the Administrative Agent or such Lender is required to repay such refund or credit to such Governmental Authority.

(i) Payment. If the Administrative Agent or any Lender becomes entitled to receive payment of Taxes, Other Taxes or additional sums pursuant to this Section 2.13, it shall give notice and demand thereof to the Borrower, and the Borrower (unless the Administrative Agent or Lender shall withdraw such notice and demand or the Borrower is not obligated to pay such amounts) shall pay such Taxes, Other Taxes or additional sums within 30 days after the Borrower’s receipt of such notice and demand.

Section 2.14 Replacement of Lenders. If the Borrower is required pursuant to Section 2.8(c), 2.11 or 2.13 to make any additional payment to any Lender or if any Lender’s obligation to make or continue, or to convert Base Rate Advances into, Eurodollar Advances shall be suspended pursuant to 2.4(c)(iii) or 2.9, or if any Lender shall fail to fund its portion of any Advance required pursuant to the terms hereof (any Lender so affected, an “Affected Lender”), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that (a) no Default shall have occurred and be continuing at the time of such replacement; (b) such replacement shall be at the Borrower’s sole expense and effort, including the payment of the processing fee referenced in Section 9.7(a)); (c) concurrently with such replacement, another bank or other entity (which entity shall be an Eligible Assignee), as of such date, shall purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit A and shall become a Lender for all purposes under this Agreement and shall assume all obligations of the Affected Lender which as to the Affected Lender shall be terminated as of such date and shall comply with the requirements of Section 9.7 applicable to assignments; and (d) concurrently with such replacement, the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 2.8(c), 2.11 and 2.13. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or Issuing Lender, as applicable, or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

Section 2.15 Increase in Commitments.

(a) At any time prior to the Revolving Maturity Date, the Borrower may effectuate increases in the aggregate Revolving Commitments (each such increase being a “Commitment Increase”), by designating either one or more of the existing Lenders (each of which, in its sole discretion, may determine whether and to what degree to participate in such Commitment Increase) or one or more other Eligible Assignees that at the time agree, in the case of any such Eligible Assignee that is an existing Lender to increase its Revolving Commitment as such Lender shall so select (an “Increasing Lender”) and, in the case of any other Eligible Assignee

-46-

that is not an existing Lender (an “Additional Lender”), to become a party to this Agreement as a Revolving Lender; provided, however, that (i) each Commitment Increase shall be of at least $1,000,000, (ii) the aggregate amount of all Commitment Increases shall not exceed $15,000,000 and the aggregate Revolving Commitments, after giving effect to all Commitment Increases, shall not exceed $40,000,000, and (iii) all Revolving Commitments and Revolving Advances provided pursuant to a Commitment Increase shall be available on the same terms as those applicable to the existing Revolving Commitments and Revolving Advances. The sum of the increases in the Revolving Commitments of the Increasing Lenders plus the Revolving Commitments of the Additional Lenders upon giving effect to a Commitment Increase shall not, in the aggregate, exceed the amount of such Commitment Increase. The Borrower shall provide prompt notice of any proposed Commitment Increase pursuant to this Section 2.15 to the Administrative Agent and the Lenders. This Section 2.15 shall not be construed to create any obligation on the Administrative Agent or any of the Lenders to advance or to commit to advance any credit to the Borrower or to arrange for any other Person to advance or to commit to advance any credit to the Borrower.

(b) A Commitment Increase shall become effective on the date (the “Increase Date”) on or prior to which the following conditions shall have been satisfied: (i) the receipt by the Administrative Agent of (A) an agreement in form and substance reasonably satisfactory to the Administrative Agent signed by the Borrower, each Increasing Lender and each Additional Lender, setting forth the Revolving Commitments, if any, of each such Lender and setting forth the agreement of each Additional Lender to become a party to this Agreement and to be bound by all the terms and provisions hereof binding upon each Lender, and (B) such evidence of appropriate authorization on the part of the Borrower with respect to such Commitment Increase as the Administrative Agent may reasonably request, (ii) the funding by each Increasing Lender and Additional Lender of the Advances to be made by each such Lender to effect the prepayment requirement set forth in Section 2.4(c)(vii), and (iii) receipt by the Administrative Agent of a certificate of an authorized officer of the Borrower stating that, both before and after giving effect to such Commitment Increase, no Default has occurred and is continuing, and that all representations and warranties made by the Borrower in this Agreement are true and correct in all material respects, unless such representation or warranty relates to an earlier date which remains true and correct in all material respects as of such earlier date.

(c) Notwithstanding any provision contained herein to the contrary, from and after the date of any Commitment Increase, all calculations and payments of interest on the Revolving Advances shall take into account the actual Revolving Commitment of each Lender and the principal amount outstanding of each Revolving Advance made by such Lender during the relevant period of time.

(d) On each Increase Date, each Lender’s share of the Letter of Credit Exposure on such date shall automatically be deemed to equal such Lender’s applicable pro rata share of such Letter of Credit Obligations (such pro rata share for such Lender to be determined as of the Increase Date in accordance with its Revolving Commitment on such date as a percentage of the aggregate Revolving Commitment on such date) without further action by any party.

Additionally, except as disclosed in writing to the Administrative Agent and the Lenders, there is no pending or, to the knowledge of the Borrower, threatened action or proceeding instituted against any of the Borrower or any of Subsidiary of the Borrower which seeks to adjudicate any of the Borrower or any of Subsidiary of the Borrower as bankrupt or insolvent, or seeking liquidation, winding up, reorganization, arrangement, adjustment, protection, relief, or composition of it or its debts under any law relating to bankruptcy, insolvency or reorganization or relief of debtors, or seeking the entry of an order for relief or the appointment of a receiver, trustee or other similar official for it or for any substantial part of its Property; provided that this Section 4.7 does not apply with respect to Environmental Claims.

Section 4.8 Compliance with Agreements.

(a) Neither the Borrower nor any of its Subsidiaries is a party to any indenture, loan or credit agreement or any lease or any other types of agreement or instrument or subject to any charter or corporate restriction or provision of applicable law or governmental regulation the performance of or compliance with which could reasonably be expected to cause a Material Adverse Change. Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any contract, agreement, lease or any other types of agreement or instrument to which the Borrower or such Subsidiary is a party and which could reasonably be expected to cause a Material Adverse Change. To the best knowledge of the Borrower, neither the Borrower nor any of its Subsidiaries is in default under, or has received a notice of default under, any contract, agreement, lease or any other document or instrument to which the Borrower or its Subsidiaries is a party which is continuing and which, if not cured, could reasonably be expected to cause a Material Adverse Change.

(b) No Default has occurred and is continuing.

Section 4.9 Pension Plans. (a) Except for matters that could not reasonably be expected to result in a Material Adverse Change, all Plans are in compliance in all material respects with all applicable provisions of ERISA, (b) no Termination Event has occurred with respect to any Plan that would result in an Event of Default under Section 7.1(i), and, except for matters that could not reasonably be expected to result in a Material Adverse Change, each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code, (c) no “accumulated funding deficiency” (as defined in Section 302 of ERISA) has occurred, and for plan years after December 31, 2007, no unpaid minimum required contribution exists, and there has been no excise tax imposed under Section 4971 of the Code, (d) to the knowledge of Borrower, no Reportable Event has occurred with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in accordance with applicable provisions of ERISA and the Code, (e) the

-54-

present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits in an amount that could reasonably be expected to result in a Material Adverse Change, (f) neither the Borrower nor any member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which there is any unsatisfied withdrawal liability that could reasonably be expected to result in a Material Adverse Change or an Event of Default under Section 7.1(j), and (g) except for matters that could not reasonably result in a Material Adverse Change, as of the most recent valuation date applicable thereto, neither the Borrower nor any member of the Controlled Group would become subject to any liability under ERISA if the Borrower or any Subsidiary of the Borrower has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, the Borrower has no reason to believe that the annual cost during the term of this Agreement to the Borrower or any Subsidiary of the Borrower for post-retirement benefits to be provided to the current and former employees of the Borrower or any Subsidiary of the Borrower under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

ARTICLE 8

THE ADMINISTRATIVE AGENT

Section 8.1 Appointment, Powers, and Immunities. Each Lender hereby irrevocably appoints and authorizes the Administrative Agent to act as its agent under this Agreement and the other Credit Documents with such powers and discretion as are specifically delegated to the Administrative Agent by the terms of this Agreement and the other Credit Documents, together with such other powers as are reasonably incidental thereto. The Administrative Agent (which term as used in this sentence and in Section 8.5 and the first sentence of Section 8.6 shall include its Affiliates and its own and its Affiliates’ officers, directors, employees, and agents): (a) shall not have any duties or responsibilities except those expressly set forth in this Agreement and shall not be a trustee or fiduciary for any Lender; (b) shall not be responsible to the Lenders for any recital, statement, representation, or warranty (whether written or oral) made in or in connection with any Credit Document or any certificate or other document referred to or provided for in, or received by any of them under, any Credit Document, or for the value, validity, effectiveness, genuineness, enforceability, or sufficiency of any Credit Document, or any other document referred to or provided for therein or for any failure by any Credit Party or any other Person to perform any of its obligations thereunder; (c) shall not be responsible for or have any duty to ascertain, inquire into, or verify the performance or observance of any covenants or agreements by any Credit Party or the satisfaction of any condition or to inspect the Property (including the books and records) of any Credit Party or any of its Subsidiaries or Affiliates; (d) shall not be required to initiate or conduct any litigation or collection proceedings under any Credit Document unless requested by the Majority Lenders in writing and it receives indemnification satisfactory to it from the Lenders; and (e) shall not be responsible for any action taken or omitted to be taken by it under or in connection with any Credit Document, except for its own gross negligence or willful misconduct. The Administrative Agent may employ agents and attorneys-in-fact and shall not be responsible for the negligence or misconduct of any such agents or attorneys-in-fact selected by the Administrative Agent with reasonable care.

Section 8.2 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon any certification, notice, instrument, writing, or other communication (including, without limitation, any thereof by telephone or telecopy) believed by it to be genuine and correct and to have been signed, sent or made by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel (including counsel for any Credit Party), independent accountants, and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Notes as the holder thereof for all purposes hereof unless and until the Administrative Agent receives and accepts an Assignment and Acceptance executed in accordance with Section 9.7. As to any matters not expressly provided for by this Agreement, the Administrative Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be

-78-

fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding on all of the Lenders; provided, however, that the Administrative Agent shall not be required to take any action that exposes the Administrative Agent to personal liability or that is contrary to any Credit Document or applicable law or unless it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking any such action.

Section 8.3 Defaults. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of a Default or Event of Default unless the Administrative Agent has received written notice from a Lender or the Borrower specifying such Default or Event of Default and stating that such notice is a “Notice of Default”. In the event that the Administrative Agent receives such a notice of the occurrence of a Default or Event of Default, the Administrative Agent shall give prompt notice thereof to the Lenders. The Administrative Agent shall (subject to Section 8.2) take such action with respect to such Default or Event of Default as shall reasonably be directed by the Majority Lenders, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interest of the Lenders.

Section 8.4 Rights as Lender. With respect to its Commitments and the Advances made by it, Wells Fargo (and any successor acting as Administrative Agent) in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as the Administrative Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. Wells Fargo (and any successor acting as Administrative Agent) and its Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to, make investments in, provide services to, and generally engage in any kind of lending, trust, or other business with any Credit Party or any of its Subsidiaries or Affiliates as if it were not acting as Administrative Agent, and Wells Fargo (and any successor acting as Administrative Agent) and its Affiliates may accept fees and other consideration from any Credit Party or any of its Subsidiaries or Affiliates for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

Section 8.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender agrees that it has, independently and without reliance on the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and the other Credit Parties and decision to enter into this Agreement and that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under the Credit Documents. Except for notices, reports, and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder and for other information in the Administrative Agent’s possession which has been requested by a Lender and for which such Lender pays the Administrative Agent’s expenses in connection therewith, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition, or business of any Credit Party or any of its Subsidiaries or Affiliates that may come into the possession of the Administrative Agent or any of its Affiliates.

Section 8.7 Resignation of Administrative Agent and Issuing Lender. The Administrative Agent or the Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Borrower. Upon receipt of notice of any such resignation, the Majority Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, so long as no Event of Default has occurred and is continuing, the consent of the Borrower, which consent shall not be unreasonably withheld. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Majority Lenders with the consent of the Borrower, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s or Issuing Lender’s giving of notice of resignation, then the retiring Administrative Agent or Issuing Lender may, on behalf of the Lenders and the Borrower, appoint a successor Administrative Agent or Issuing Lender, which shall be, in the case of a successor agent, a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $250,000,000.00 and, in the case of the Issuing Lender, a Lender. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Administrative Agent or Issuing Lender, and the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Credit Documents, except that the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent’s or Issuing

-81-

Lender’s resignation as Administrative Agent or Issuing Lender, the provisions of this Article 8 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Credit Documents.

Section 8.8 Collateral Matters.

(a) The Administrative Agent is authorized on behalf of the Secured Parties, without the necessity of any notice to or further consent from such Secured Parties, from time to time, to take any actions with respect to any Collateral or Security Documents which may be necessary to perfect and maintain the Liens upon the Collateral granted pursuant to the Security Documents. The Administrative Agent is further authorized (but not obligated) on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any action in exigent circumstances as may be reasonably necessary to preserve any rights or privileges of the Secured Parties under the Credit Documents or applicable Legal Requirements.

All notices and other communications (other than Notices of Borrowing and Notices of Continuation or Conversion, which are governed by Article 2 of this Agreement) shall be in writing and hand delivered with written receipt, telecopied, sent by facsimile (with a hard copy sent as otherwise permitted in this Section 9.9), sent by a nationally recognized overnight courier, or sent by certified mail, return receipt requested as follows: if to the Borrower or a Guarantor, as specified on Schedule II and if to any Lender, the Swing Line Lender, or the Issuing Lender, at its credit contact specified under its name on Schedule II. Each party may change its notice address by written notification to the other parties. All such notices and communications shall be effective when delivered, except that notices and communications to any Lender, Swing Line Lender, or the Issuing Lender pursuant to Article 2 shall not be effective until received and, in the case of telecopy, such receipt is confirmed by such Lender, Swing Line Lender or Issuing Lender, as applicable, verbally or in writing.

Section 9.10 Business Loans. The Borrower warrants and represents that the Obligations evidenced by the Notes are and shall be for business, commercial, investment or other similar purposes and not primarily for personal, family, household or agricultural use, as such terms are used in Chapter One (“Chapter One”) of the Texas Credit Code. At all such times, if any, as Chapter One shall establish a Maximum Rate, the Maximum Rate shall be the “indicated rate ceiling” (as such term is defined in Chapter One) from time to time in effect.

Section 9.11 Usury Not Intended. It is the intent of the Borrower and each Lender in the execution and performance of this Agreement and the other Credit Documents to contract in strict compliance with applicable usury laws, including conflicts of law concepts, governing the Advances of each Lender including such applicable laws of the State of Texas, if any, and the United States of America from time to time in effect. In furtherance thereof, the Lenders and the Borrower stipulate and agree that none of the terms and provisions contained in this Agreement or the other Credit Documents shall ever be construed to create a contract to pay, as consideration for the use, forbearance or detention of money, interest at a rate in excess of the Maximum Rate and that for purposes of this Agreement “interest” shall include the aggregate of all charges which constitute interest under such laws that are contracted for, charged or received under this Agreement; and in the event that, notwithstanding the foregoing, under any circumstances the aggregate amounts taken, reserved, charged, received or paid on the Advances, include amounts which by applicable law are deemed interest which would exceed the Maximum Rate, then such excess shall be deemed to be a mistake and each Lender receiving same shall credit the same on the principal of its Notes (or if such Notes shall have been paid in full, refund said excess to the Borrower). In the event that the maturity of the Notes are accelerated by reason of any election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest may never include more than the Maximum Rate, and

-88-

excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited on the applicable Notes (or, if the applicable Notes shall have been paid in full, refunded to the Borrower of such interest). In determining whether or not the interest paid or payable under any specific contingencies exceeds the Maximum Rate, the Borrower and the Lenders shall to the maximum extent permitted under applicable law amortize, prorate, allocate and spread in equal parts during the period of the full stated term of the Notes all amounts considered to be interest under applicable law at any time contracted for, charged, received or reserved in connection with the Obligations. The provisions of this Section shall control over all other provisions of this Agreement or the other Credit Documents which may be in apparent conflict herewith.

Section 9.12 Usury Recapture. In the event the rate of interest chargeable under this Agreement at any time is greater than the Maximum Rate, the unpaid principal amount of the Advances shall bear interest at the Maximum Rate until the total amount of interest paid or accrued on the Advances equals the amount of interest which would have been paid or accrued on the Advances if the stated rates of interest set forth in this Agreement had at all times been in effect. In the event, upon payment in full of the Advances, the total amount of interest paid or accrued under the terms of this Agreement and the Advances is less than the total amount of interest which would have been paid or accrued if the rates of interest set forth in this Agreement had, at all times, been in effect, then the Borrower shall, to the extent permitted by applicable law, pay the Administrative Agent for the account of the Lenders an amount equal to the difference between (i) the lesser of (A) the amount of interest which would have been charged on its Advances if the Maximum Rate had, at all times, been in effect and (B) the amount of interest which would have accrued on its Advances if the rates of interest set forth in this Agreement had at all times been in effect and (ii) the amount of interest actually paid under this Agreement on its Advances. In the event the Lenders ever receive, collect or apply as interest any sum in excess of the Maximum Rate, such excess amount shall, to the extent permitted by law, be applied to the reduction of the principal balance of the Advances, and if no such principal is then outstanding, such excess or part thereof remaining shall be paid to the Borrower.

Section 9.13 Governing Law; Submission to Jurisdiction. This Agreement, the Notes and the other Credit Documents (unless otherwise expressly provided therein) shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas. Without limiting the intent of the parties set forth above, (a) Chapter 346 of the Texas Finance Code, as amended (relating to revolving loans and revolving tri-party accounts (formerly Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect. Each Letter of Credit shall be governed by the Uniform Customs and Practice for Documentary Credits, International Chamber of Commerce Publication No. 500 (1993 version). The Borrower hereby irrevocably submits to the jurisdiction of any Texas state or federal court sitting in Houston, Texas in any action or proceeding arising out of or relating to this Agreement or the other Credit Documents, and the Borrower hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court. The Borrower hereby unconditionally and irrevocably waives, to the fullest extent it may effectively do so, any right it may have to the defense of an inconvenient

-89-

forum to the maintenance of such action or proceeding. The Borrower hereby agrees that service of copies of the summons and complaint and any other process which may be served in any such action or proceeding may be made by mailing or delivering a copy of such process to such Borrower at its address set forth in this Agreement. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section shall affect the rights of any Lender to serve legal process in any other manner permitted by the law or affect the right of any Lender to bring any action or proceeding against the Borrower or its Property in the courts of any other jurisdiction.

Section 9.14 Execution in Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.

Section 9.15 Waiver of Jury. THE BORROWER, THE LENDERS, THE ADMINISTRATIVE AGENT, THE ISSUING LENDER, AND THE SWING LINE LENDER HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY JURY IN RESPECT OF ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER CREDIT DOCUMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 9.16 USA Patriot Act. Each Lender that is subject to the Patriot Act and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the Patriot Act it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrower in accordance with the Patriot Act.

PURSUANT TO SECTION 26.02 OF THE TEXAS BUSINESS AND COMMERCE CODE, A LOAN AGREEMENT IN WHICH THE AMOUNT INVOLVED IN THE LOAN AGREEMENT EXCEEDS $50,000.00 IN VALUE IS NOT ENFORCEABLE UNLESS THE LOAN AGREEMENT IS IN WRITING AND SIGNED BY THE PARTY TO BE BOUND OR THAT PARTY’S AUTHORIZED REPRESENTATIVE.

THE RIGHTS AND OBLIGATIONS OF THE PARTIES TO AN AGREEMENT SUBJECT TO THE PRECEDING PARAGRAPH SHALL BE DETERMINED SOLELY FROM THE WRITTEN LOAN AGREEMENT, AND ANY PRIOR ORAL AGREEMENTS BETWEEN THE PARTIES ARE SUPERSEDED BY AND MERGED INTO THE LOAN AGREEMENT. THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS, AS DEFINED IN THIS AGREEMENT, REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES WITH RESPECT TO THE SUBJECT MATTERS SET FORTH HEREIN AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
