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 Lender may record and otherwise treat the making of such Revolving Borrowings as the making of a Revolving Borrowing to the Borrower

-27-

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 Revolving 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 2.2 and regardless of whether (A) the conditions in Section 3.2 have been met, (B) such notice complies with Section 2.3, 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 Pro Rata Share of the amount of such Revolving Advance not later than 12:00 noon 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 any Credit Party 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 (including in the case of each Existing Letter of Credit, the deemed issuance with respect thereto on the Effective Date), 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 Obligations equal to such Lender’s 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:

-28-

(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 fifth Business 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 fifth Business Day prior to the Revolving Maturity Date, and to be held in the Cash Collateral Account and applied in accordance with paragraph (h) 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;

(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

-29-

(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(a), 2.2(f), 2.4(c), 2.14, 7.2(b) or 7.3(b) or any other provision under this Agreement, 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 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 any surplus funds held in the Cash Collateral Account above the Letter of Credit Exposure to the Borrower at the Borrower’s written request.

(iii) Funds held in the Cash Collateral Account may 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 obligation to make any 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) Defaulting Lender. If, at any time, a Defaulting Lender exists hereunder, then, at the request of the Issuing Lender subject to Section 2.14(c), the Borrower shall deposit funds with Administrative Agent into the Cash Collateral Account an amount equal to such Defaulting Lender’s Pro Rata Share of the Letter of Credit Exposure.

-30-

(j) Letters of Credit Issued for Guarantors or any Subsidiary. 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. Advances.

(a) Notice. Each Borrowing (other than the Borrowings to be made on the Effective Date), shall be made pursuant to the applicable Notice of Borrowing given by the Borrower to the Administrative Agent not later than (i) 11:00 a.m. (Houston, Texas time) on the third Business Day before the date of the proposed Borrowing, in the case of a Eurodollar Advance or (ii) 11:00 a.m. (Houston, Texas time) on the Business Day before the date of the proposed Borrowing, in the case of a Base Rate Advance, by the Borrower to the Administrative Agent, which shall give to each Lender prompt notice of such proposed Borrowing, by facsimile or telex. The Borrowings to be made on the Effective Date shall be made pursuant to the applicable Notices of Borrowing given not later than 11:00 a.m. (Houston, Texas time) on the Effective Date by the Borrower to the Administrative Agent, which shall give to each Lender prompt notice of such proposed Borrowing, by facsimile or telex. Each Notice of Borrowing shall be by facsimile or telex, confirmed promptly by the Borrower with a hard copy (other than with respect to notice sent by facsimile), specifying (i) the requested date of such Borrowing, (ii) the requested Type and Class of Advances comprising such Borrowing, (iii) the aggregate amount of such Borrowing, and (iv) if such Borrowing is to be comprised of Eurodollar Advances, the requested Interest Period for each such Advance; provided that, and all Borrowings to be made on the Effective Date shall consist only of Base Rate Advance which may, subject to the terms of this Agreement, be thereafter Converted into Eurodollar Advances. In the case of a proposed Borrowing comprised of Eurodollar Advances, the Administrative Agent shall promptly notify each Lender of the applicable interest rate under Section 2.7(b). Each Lender shall, before 12:00 noon (Houston, Texas time) on the date of such Borrowing (or, in the case of Borrowings on the Effective Date, 2:00 p.m. (Houston, Texas time)), make available for the account of its applicable Lending Office to the Administrative Agent at its address referred to in Section 9.9, or such other location as the Administrative Agent may specify by notice to the Lenders, in same day funds, such Lender’s Pro Rata Share of such Borrowing. After the Administrative Agent’s receipt of such funds and upon fulfillment of the applicable conditions set forth in Article 3, the Administrative Agent will make such funds available to the Borrower at its account with the Administrative Agent or as otherwise directed by the Borrower with written notice to the Administrative Agent.

(b) Conversions and Continuations. In order to elect to Convert or continue a Revolving Advance or a Term Advance under this paragraph, the Borrower shall deliver an irrevocable Notice of Continuation or Conversion to the Administrative Agent at the Administrative Agent’s office no later than 11:00 a.m. (Houston, Texas time) (i) on the Business Day before the date of the proposed conversion date in the case of a Conversion to a Base Rate Advance and (ii) at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, a Eurodollar Advance. Each such Notice of Continuation or Conversion shall be in writing or by telex or facsimile confirmed promptly by the Borrower with a hard copy (other than with respect to notice sent by facsimile), specifying (i) the requested Conversion or continuation date (which shall be a Business Day), (ii) the amount, Type, and Class of the Advance to be Converted or continued, (iii) whether a Conversion or continuation is requested and, if a Conversion, into what Type of Advance, and (iv) in the case of a

-31-

Conversion to, or a continuation of, a Eurodollar Advance, the requested Interest Period. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Administrative Agent shall provide each Lender with a copy thereof and, in the case of a Conversion to or a Continuation of a Eurodollar Advance, notify each Lender of the applicable interest rate under Section 2.7(b). The portion of Advances comprising part of the same Borrowing that are Converted to Advances of another Type shall constitute a new Borrowing.

(i) at no time shall there be more than seven Interest Periods applicable to outstanding Eurodollar Advances;

(ii) the Borrower may not select Eurodollar Advances for any Borrowing at any time when an Event of Default has occurred and is continuing;

(iii) if any Lender shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent 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 Eurodollar Advances or to fund or maintain Eurodollar Advances, (A) the obligation of such Lender to make such Eurodollar Advance as part of the requested Borrowing or for any subsequent Borrowing shall be suspended until such Lender shall notify the Borrower that the circumstances causing such suspension no longer exist and such Lender’s portion of such requested Borrowing or any subsequent Borrowing of Eurodollar Advances shall be made in the form of a Base Rate Advance, and (B) such Lender agrees to use commercially reasonable efforts (consistent with its internal policies and legal and regulatory restrictions) to designate a different 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;

(iv) if the Administrative Agent is unable to determine the Eurodollar Rate for Eurodollar Advances comprising any requested Borrowing, the right of the Borrower to select Eurodollar Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance;

(v) if the Majority Lenders shall, at least one Business Day before the date of any requested Borrowing, notify the Administrative Agent that the Eurodollar Rate for Eurodollar Advances comprising such Borrowing will not adequately reflect the cost to such Lenders of making or funding their respective Eurodollar Advances, as the case may be, for such Borrowing, the right of the Borrower to select Eurodollar Advances for such Borrowing or for any subsequent Borrowing shall be suspended until the Administrative Agent shall notify the Borrower and the Lenders that the circumstances causing such suspension no longer exist, and each Advance comprising such Borrowing shall be a Base Rate Advance; and

(vi) if the Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Advances in accordance with the provisions contained in the definition of Interest Period in Section 1.1 and paragraph (b) above, the Administrative Agent will forthwith so notify the Borrower and the Lenders and such Advances will be made available to the Borrower on the date of such Borrowing as Eurodollar Advances with an interest period duration of one month or, in the case of continuation of an existing Advance, Convert into Base Rate Advances.

-32-

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Continuation or Conversion delivered by the Borrower hereunder, including its deemed request for borrowing made under Section 2.2(c), shall be irrevocable and binding on the Borrower.

(e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Revolving Borrowing that such Lender will not make available to the Administrative Agent such Lender’s Pro Rata Share of any Borrowing, the Administrative Agent may assume that such Lender has made its Pro Rata Share of such Borrowing available to the Administrative Agent on the date of such Borrowing in accordance with Section 2.3(a), and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Lender shall not have so made its Pro Rata Share of such Borrowing available to the Administrative Agent, such Lender and the Borrower severally agree to immediately repay to the Administrative Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the lesser of (A) the Federal Funds Rate for such day for the first three days and thereafter the interest rate applicable to the Advance and (B) the Maximum Rate. If such Lender shall repay to the Administrative Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Lender’s Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing.

(f) Swing Line Advances.

(i) Facility. 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 may, in its sole discretion, 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), and in an aggregate outstanding principal amount not to exceed the Swing Line Sublimit Amount at any time; provided that (A) after giving effect to such Swing Line Advance, the sum of the aggregate 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 Commitments in effect at such time; (B) 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 Line Advance, it being agreed by the Borrower that the giving of the applicable Notice of Revolving 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; (C) only if an AutoBorrow Agreement is not in effect, each Swing Line Advance shall be in an aggregate amount not less than $100,000 and in integral multiples of $50,000 in excess thereof; and (D) if an AutoBorrow Agreement is in effect, such additional terms and conditions of such AutoBorrow Agreement shall have been satisfied, and in the event that any of the terms of this Section 2.3(f)(i) conflict with such AutoBorrow Agreement, the terms of the AutoBorrow Agreement shall govern and control. 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.

-33-

(ii) Prepayment. Within the limits expressed in this Agreement, amounts advanced pursuant to Section 2.3(f)(i) 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 Sublimit Amount, the Borrower shall 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.

(iii) Reimbursements for Swing Line Obligations.

(A) 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. The Borrower may, with a written notice request that such obligations to the Swing Line Lender 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 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. 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 2.3(a), or (C) a Default exists, make available such Lender’s Pro Rata 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 for 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 obligations under the Swing Line Note, but only to provide an additional method of payment therefor. The making of any Revolving Borrowing under this Section 2.3(f)(iii)(A) 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 Swing Line Note.

(B) If at any time, the 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

-34-

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 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.

(C) 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(f), 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(f) 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.

(iv) 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 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 Revolving 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 Swing Line Lender.

(v) 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 (iii) 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.

-35-

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

(vii) Discretionary Nature of the Swing Line Facility. Notwithstanding any terms to the contrary contained herein or in any AutoBorrow Agreement, the swing line facility provided herein or in any AutoBorrow Agreement (i) is an uncommitted facility and the Swing Line Lender may, but shall not be obligated to, make Swing Line Advances, and (ii) may be terminated at any time by the Swing Line Lender upon written notice to the Borrower.

Section 2.4. Prepayments.

(a) Right to Prepay; Ratable Prepayment. The Borrower shall have no right to prepay any principal amount of any Advance except as provided in this Section 2.4 and all notices given pursuant to this Section 2.4 shall be irrevocable and binding upon the Borrower. Each payment of any Advance pursuant to this Section 2.4 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part other than Advances owing to a Defaulting Lender as provided in Section 2.14.

(b) Optional. The Borrower may elect to prepay any of the Advances without penalty or premium except as set forth in Section 2.9 and after giving by 11:00 a.m. (Houston, Texas time) (i) in the case of Eurodollar Advances, at least three Business Days’ or (ii) in case of Base Rate Advances, one Business Day’s prior written notice to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice is given, the Borrower shall prepay Advances comprising part of the same Borrowing in whole or ratably in part in an aggregate principal amount equal to the amount specified in such notice, together with accrued interest to the date of such prepayment on the principal amount prepaid and amounts, if any, required to be paid pursuant to Section 2.9 as a result of such prepayment being made on such date; provided that (A) each optional prepayment of Eurodollar Advances shall be in a minimum amount not less than $500,000 and in multiple integrals of $100,000 in excess thereof, (B) each optional prepayment of Base Rate Advances shall be in a minimum amount not less than $500,000 and in multiple integrals of $50,000 in excess thereof, and (C) only if an AutoBorrow Agreement is not in effect, each optional prepayment of Swing Line Advances shall be in a minimum amount not less than $250,000 and in multiple integrals of $50,000 in excess thereof. If an AutoBorrow Agreement is in effect, each prepayment of Swing Line Advances shall be made as provided in such AutoBorrow Agreement. Notwithstanding the foregoing, the Borrower may (subject to payment to the Lenders of any applicable amounts under Section 2.9 hereof) rescind or postpone any notice of prepayment under this Section 2.4(b) if such prepayment would have resulted from a refinancing of this Agreement, which refinancing shall not be consummated or shall otherwise be delayed.

(i) On any date that (a) the sum of the outstanding principal amount of all Swing Line Advances and all Revolving Advances plus the Letter of Credit Exposure exceeds (b) the aggregate amount of Commitments, as notified to the Borrower by the Administrative Agent (with such calculation set forth in reasonable detail which shall be conclusive absent manifest error), the Borrower shall, within one Business Day, to the extent of such excess, first prepay to the Swing Line Lender the outstanding principal amount of the Swing Line Advances, second prepay to the Lenders on a pro rata basis the outstanding principal amount of the Revolving Advances, and third make deposits into the Cash Collateral Account to provide cash collateral in the amount of such excess for the Letter of Credit Exposure.

(b) Eurodollar Advances. Each Eurodollar Advance shall bear interest during its Interest Period equal to at all times the Eurodollar Rate for such Interest Period plus the Applicable Margin for Eurodollar Advances for such period.

(c) 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, 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 (iii) the Borrower shall immediately, without further action by the Administrative Agent, any Lender or any 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. This Section 2.7(c) shall not limit the rights of the Administrative Agent and Lenders with respect to the Default Rate as set forth in Section 2.7(d).

-39-

(d) Default Rate. Notwithstanding the foregoing, (i) upon the occurrence and during the continuance of an Event of Default under Section 7.1(a) or Section 7.1(g), all overdue amounts shall bear interest, after as well as before judgment, at the Default Rate and (ii) upon the occurrence and during the continuance of any Event of Default (including under Section 7.1(a) and Section 7.1(g)), upon the request of the Majority Lenders, all Obligations shall bear interest, after as well as before judgment, at the Default Rate. Interest accrued pursuant to this Section 2.7(d) and all interest accrued but unpaid on or after the Revolving Maturity Date or the Term Maturity Date shall be due and payable on demand.

Section 2.8. Illegality. If any Lender shall notify the Borrower that any Change in Law 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 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 2.9 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 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 2.9. Breakage Costs. Upon demand of any Lender (with a copy to the Administrative Agent) from time to time, the Borrower shall promptly compensate such Lender for and hold such Lender harmless from any loss, cost or expense incurred by it as a result of:

(a) any continuation, conversion, payment or prepayment (including any deemed payment or repayment and any reallocated repayment to Non-Defaulting Lenders provided for in Section 2.11(a) or Section 2.14) of any Advance other than a Base Rate Advance on a day other than the last day of the Interest Period for such Advance (whether voluntary, mandatory, automatic, by reason of acceleration, or otherwise);

(b) any failure by the Borrower (for a reason other than the failure of such Lender to make an Advance) to prepay, borrow, continue or Convert any Advance other than a Base Rate Advance on the date or in the amount notified by the Borrower; or

(c) any assignment of an Eurodollar Advance on a day other than the last day of the Interest Period therefor as a result of a request by the Borrower pursuant to Section 2.13;

including any loss of anticipated profits, any foreign exchange losses and any loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain such Advance, from fees payable to terminate the deposits from which such funds were obtained or from the performance of any foreign

-40-

exchange contract. The Borrower shall also pay any customary administrative fees charged by such Lender in connection with the foregoing. For purposes of calculating amounts payable by the Borrower to the Lenders under this Section 2.9, the requesting Lender shall be deemed to have funded the Eurodollar Advances made by it at the Eurodollar Base Rate used in determining the Eurodollar Rate for such Advance by a matching deposit or other borrowing in the offshore interbank market for Dollars for a comparable amount and for a comparable period, whether or not such Eurodollar Advance was in fact so funded.

Section 2.10. Increased Costs.

(a) Eurodollar Advances. If any Change in Law shall:

(i) impose, modify, or deem applicable any reserve, special deposit, compulsory loan, insurance charge, 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 any Lender (or its applicable Lending Office), including the Commitments of such Lender hereunder; or

(ii) 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 date hereof, any Lender or the Issuing Lender shall have determined that any Change in Law affecting such Lender or Issuing Lender or any Lending Office of such Lender or such Lender’s or Issuing Lender’s holding company, if any, regarding capital or liquidity requirements 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 Change in Law (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 date hereof, which will entitle such Lender to compensation pursuant to this Section 2.10 and will designate a different 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 2.10 shall furnish to the Borrower and the Administrative Agent a statement setting forth the 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.

-41-

(d) Delay in Requests. Failure or delay on the part of any Lender or Issuing Lender to demand compensation pursuant to this Section 2.10 shall not constitute a waiver of such Lender’s or such Issuing Lender’s right to demand such compensation, provided that the Borrower shall not be required to compensate a Lender or Issuing Lender pursuant to this Section 2.10 for any increased costs incurred or reductions suffered more than 180 days prior to the date that such Lender or Issuing Lender, as the case may be, notifies the Borrower and the Administrative Agent of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or Issuing Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof).

Section 2.11. 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; provided that, the Borrower may setoff amounts owing to any Lender that is at such time a Defaulting Lender against Advances that such Defaulting Lender failed to fund to the Borrower under this Agreement (the “Unfunded Advances”) so long as (i) the Borrower shall have delivered prior written notice of such setoff to the Administrative Agent and such Defaulting Lender, (ii) the Advances made by the Non-Defaulting Lenders as part of the original Borrowing to which the Unfunded Advances applied shall still be outstanding, (iii) if such Defaulting Lender failed to fund Advances under more than one Borrowing, such setoff shall be applied in a manner satisfactory to the Administrative Agent, and (iv) upon the application of such setoff, the Unfunded Advances shall be deemed to have been made by such Defaulting Lender on the effective date of such setoff.

(b) Payment Procedures. The Borrower shall make each payment under this Agreement and under the Notes not later than 1:00 p.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, 2.9, 2.10, 2.12, 2.13, and 9.2 and such other provisions herein which expressly provide for payments to a specific Lender, but after taking into account payments effected pursuant to Section 9.1) in accordance with each Lender’s ~~Pro Rata~~ ~~Share~~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.

-42-

(d) Computations. All computations of interest for Base Rate Advances shall be made by the Administrative Agent on the basis of a year of 365/366 days and all computations of all other interest and fees shall be made by the Administrative Agent on the basis of a year of 360 days, 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 (other than as a result of a termination of a Defaulting Lender’s Commitment under Section 2.1(b)(ii), the setoff right of the Borrower under clause (a) above, or the non-pro rata application of payments provided in the last sentence of this clause (e)), such Lender shall notify the other Lenders 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 2.11(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. If a Lender fails to fund a Revolving Advance with respect to a Borrowing as and when required hereunder and the Borrower subsequently makes a repayment of any Revolving Advances, then, after taking into account any setoffs made pursuant to Section 2.11(a) above, such payment shall be applied among the Non-Defaulting Lenders ratably in accordance with their respective Commitment percentages until each Lender (including any Lender that is at such time a Defaulting Lender) has its percentage of all of the outstanding Revolving Advances and the balance of such repayment shall be applied among the Lenders in accordance with their Pro Rata Share. The provisions of this Section 2.11(e) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Advances or participations in Letter of Credit Exposure to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 2.11(e) shall apply).

Section 2.12. Taxes.

(a) No Deduction for Certain Taxes. Any and all payments by any Credit Party under any of the Credit Documents to the Administrative Agent, the Issuing Lender, or a Lender shall be made, in accordance with Section 2.11, 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 or measured by its net income or profits (however denominated) and franchise (or margin) taxes imposed on it by the jurisdiction (or any political subdivision thereof) (A) under the laws of which (or under the laws of a political subdivision of which) it is organized or in which its principal executive office is located or, in the case of a Lender, the laws of which (or under the laws of a political subdivision of which) such Lender’s applicable Lending Office is located, or (B) as a result of a present or former connection between it and the jurisdiction (or any political subdivision thereof) imposing such tax (other than any

-43-

such connection arising solely from it having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Credit Document); (ii) branch profits taxes imposed by the United States of America or any similar taxes imposed by any jurisdiction described in (i); (iii) in the case of a Lender other than a Lender that becomes a party to this Agreement or any other Credit Document pursuant to an Assignment and Acceptance, 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; (iv) in the case of any Lender that becomes a party to this Agreement or any other Credit Document pursuant to an Assignment and Acceptance, any taxes imposed by the United States of America by means of withholding at the source, except to the extent that, pursuant to this Section 2.12, amounts with respect to such taxes were payable to such Lender’s assignor immediately before such Lender became a party to this Agreement or such Credit Document with respect to its applicable ownership interest in the Commitments; and (v) any U.S. federal withholding taxes imposed under FATCA (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings, and liabilities being hereinafter referred to as “Taxes”). Except as provided in Section 2.12(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 2.12), such Lender receives an amount equal to the sum it would have received had no such deductions been made; (ii) the Borrower or the Administrative Agent, as applicable, shall make such deductions; and (iii) the Borrower or the Administrative Agent, as applicable, 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 2.12(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 2.12(f), the Borrower will indemnify 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 2.12) paid by such Lender, the Issuing Lender, or the Administrative Agent (as the case may be) and any interest and reasonable 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 any Credit Party 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, a copy of the return reporting such payment, or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Withholding Reduction or Exemption. (i) Each Foreign Lender that is entitled to an exemption from, or a reduction of, withholding tax with respect to payments under this Agreement or under any other Credit Document shall, to the extent that it is legally entitled to do so, deliver to the Borrower (with a copy to the Administrative Agent), on or before the date it becomes a party to this Agreement and from time to time thereafter at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without, or at a reduced rate of, withholding. In addition, any Lender shall, to the extent that it is legally entitled to do so, deliver to

-44-

Borrower (with a copy to the Administrative Agent), on or before the date it becomes a party to this Agreement and from time to time thereafter at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine that such Lender is not subject to United States backup withholding and whether or not such Lender is subject to United States information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 2.12(e)(ii)(A), (B) and (C) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, each Lender shall deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient), on or before the date on which such Lender becomes a party to this Agreement and from time to time thereafter at the time or times prescribed by applicable law or reasonably requested by the Borrower or Administrative Agent, whichever of the following is applicable:

(A) In the case of any Lender that is not a Foreign Lender, duly completed and executed originals of IRS Form W-9 (or any successor form) certifying that such Lender is exempt from United States backup withholding;

(B) In the case of any Foreign Lender, to the extent that it is legally entitled to do so:

(1) duly completed and executed originals of IRS Form W-8BEN (or any successor form) claiming eligibility for benefits of an income tax treaty to which the United States is a party;

(2) duly completed and executed originals of IRS Form W-8ECI (or any successor form);

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, (1) a certificate to the effect that such Foreign Lender is not (a) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (b) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (c) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code, and (2) duly completed and executed originals of IRS Form W-8BEN (or any successor form); or

(4) any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in United States federal withholding tax duly completed together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower and the Administrative Agent to determine the withholding or deduction required to be made.

(C) Without limiting any of the foregoing, if a payment made to a Lender hereunder or under any other Credit Document would be subject to United States federal withholding taxes imposed pursuant to FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent, at the time or times prescribed by applicable law and at such time or times reasonably requested by the Borrower and the Administrative Agent, such documentation prescribed by applicable law

-45-

(including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower or the Administrative Agent to comply with its obligations under FATCA, to determine that such Lender has complied with its obligations under FATCA, or to determine the amount to deduct and withhold from such payment; provided, that solely for purposes of this paragraph, the term “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(D) Each Lender further agrees that it shall (i) promptly notify the Borrower and the Administrative Agent of any change in circumstances which would modify or render invalid any claimed exemption or reduction in withholding taxes, and (ii) in the event any previous form delivered by such Lender pursuant to this Section 2.12(e) expires or becomes obsolete or inaccurate, update any such form or certification or promptly deliver any such other properly completed and executed form, certification or documentation as may be required in order to confirm or establish the entitlement of such Lender to an exemption from or a reduction in withholding taxes with respect to payments hereunder or under any other Credit Document if such Lender continues to be so entitled.

(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 2.12, such Lender shall not be entitled to indemnification or the payment of additional amounts under Section 2.12(a), (b), or (c) with respect to Taxes imposed; 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 expense 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 2.12; 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, any Lender or the Issuing Lender determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 2.12, it shall pay to the Borrower an amount equal to such refund (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.12 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent, such Lender or the Issuing Lender, as the case may be, and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund), provided that the Borrower, upon the request of the Administrative Agent, such Lender or the Issuing 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, such Lender or the Issuing Lender in the event the Administrative Agent, such Lender or the Issuing Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the Administrative Agent, the Issuing Lender or any Lender be required to pay any amount to the Borrower pursuant to this paragraph (h) the payment of which would place the Administrative Agent, the Issuing Lender or such Lender in a less favorable net after-Tax position than the Administrative Agent, the Issuing Lender or such Lender would have been in

-46-

if the indemnification payments or additional amounts giving rise to such refund had never been paid. This subsection shall not be construed to require the Administrative Agent, any Lender or the Issuing Lender to make available its tax returns (or any other information relating to its taxes that it deems confidential) to any Borrower or any other Person.

(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 2.12, 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. Notwithstanding anything herein to the contrary, neither any Lender, the Issuing Bank, nor the Administrative Agent shall be indemnified for any Taxes or Other Taxes under this Section 2.12 unless such Lender, the Issuing Bank, or the Administrative Agent shall make written demand on Borrower for such reimbursement no later than 6 months after the earlier of (i) the date on which the relevant Governmental Authority makes written demand upon such Lender, the Issuing Bank, or the Administrative Agent for such Taxes or Other Taxes, and (ii) the date on which such Lender, the Issuing Bank, or the Administrative Agent has made payment of such Taxes or Other Taxes to the relevant Governmental Authority; provided that if the Taxes or Other Taxes imposed or asserted giving rise to such claims are retroactive, then the 6-month period referred to above shall be extended to include the retroactive effect thereof.

Section 2.13. Replacement of Lenders. If (a) the Borrower is required pursuant to Section 2.10 or 2.12 to make any additional payment to any Lender, (b) any Lender’s obligation to make or continue, or to Convert Base Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 2.3(c)(iii) or 2.8, or (c) any Lender is a Defaulting Lender (any such Lender described in any of the preceding clauses (a) – (c), being a “Subject Lender”), then (i) in the case of a Defaulting Lender, the Administrative Agent may, upon notice to the Subject Lender and the Borrower, require such Defaulting Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.7), all of its interests, rights and obligations under this Agreement and the related Credit Documents as a Lender to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment) and (ii) in the case of any Subject Lender, the Borrower may, upon notice to the Subject Lender and the Administrative Agent and at the Borrower’s sole cost and expense, require such Subject Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 9.7), all of its interests, rights and obligations under this Agreement and the related Credit Documents to an Eligible Assignee that shall assume such obligations (which Eligible Assignee may be another Lender, if a Lender accepts such assignment), provided that, in any event

(A) as to assignments required by the Borrower, the Borrower shall have paid to the Administrative Agent the assignment fee specified in Section 9.7;

(B) such Subject Lender shall have received payment of an amount equal to the outstanding principal of its applicable Advances and participations in outstanding Letter of Credit Obligations, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Credit Documents (including any amounts under Section 2.9) from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

(C) in the case of any such assignment resulting from a claim for compensation under Section 2.12, such assignment will result in a reduction in such compensation or payments thereafter; and

-47-

(D) such assignment does not conflict with applicable Legal Requirements.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower or the Administrative Agent to require such assignment and delegation cease to apply. Solely for purposes of effecting any assignment involving a Defaulting Lender under this Section 2.13 and to the extent permitted under applicable Legal Requirements, each Lender hereby designates and appoints the Administrative Agent as true and lawful agent and attorney-in-fact, with full power and authority, for and on behalf of and in the name of such Lender to execute, acknowledge and deliver the Assignment and Acceptance required hereunder if such Lender is a Defaulting Lender and such Lender shall be bound thereby as fully and effectively as if such Lender had personally executed, acknowledged and delivered the same. In lieu of the Borrower or the Administrative Agent replacing a Defaulting Lender as provided in this Section 2.13, the Borrower may terminate such Defaulting Lender’s Commitment as provided in Section 2.1(b)(ii).

Section 2.14. Payments and Deductions to a Defaulting Lender.

(a) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.1(a), Section 2.2, or Section 2.11 then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid in cash.

(b) If a Defaulting Lender as a result of the exercise of a set-off shall have received a payment in respect of its outstanding applicable Advances or Pro Rata Share of Letter of Credit Exposure which results in its outstanding applicable Advances and Pro Rata Share of Letter of Credit Exposure being less than its pro rata share of the aggregate outstanding applicable Advances and Letter of Credit Exposure, then no payments will be made to such Defaulting Lender until such time as all amounts due and owing to the Lenders have been equalized in accordance with each Lender’s respective pro rata share of the aggregate outstanding applicable Advances and Letter of Credit Exposure. Further, if at any time prior to the acceleration or maturity of the Advances, the Administrative Agent shall receive any payment in respect of principal attributable to an applicable Advance or Letter of Credit Obligations while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowings for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its pro rata share of all Advances then outstanding. After acceleration or maturity of the Advances, subject to the first sentence of this Section 2.14(b), all principal will be paid ratably as provided in Section 2.11(e).

(i) such Letter of Credit Exposure shall be automatically reallocated among the Non-Defaulting Lenders in accordance with their respective Pro Rata Share of such Defaulting Lender’s Pro Rata Share of the Letter of Credit Exposure (and each Lender is deemed to have purchased and assigned such participation interest in such reallocated portion of the Letter of Credit Exposure) but only to the extent that (A) the sum of each Non-Defaulting Lender’s outstanding Revolving Advances plus its share of the Letter of Credit Exposure, after giving effect to the reallocation provided herein, does not exceed such Non-Defaulting Lender’s Commitment, and (B) the conditions set forth in Section 3.2 are satisfied at such time; provided that, such reallocation shall not constitute a waiver or release of any claim the Borrower, the Administrative Agent, the Issuing Lender or any other Lender may have against such Defaulting Lender or cause such Defaulting Lender to be a Non-Defaulting Lender;

-48-

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, then the Borrower shall, within one Business Day following notice by the Administrative Agent, cash collateralize such Defaulting Lender’s share of the Letter of Credit Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.2(h) for so long as such Letter of Credit Exposure is outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s Letter of Credit Exposure pursuant to this Section 2.14 then the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.6(b)(i) or (iii) with respect to such Defaulting Lender’s Letter of Credit Exposure during the period such Defaulting Lender’s Letter of Credit Exposure is cash collateralized;

(iv) if the Letter of Credit Exposure of the Non-Defaulting Lenders is reallocated pursuant to clause (i) above, then the fees payable to the Lenders pursuant to Section 2.6(b)(i) and (iii) shall be adjusted in accordance with such Non-Defaulting Lenders’ Pro Rata Share;

(v) if any Defaulting Lender’s share of the Letter of Credit Exposure is neither cash collateralized nor reallocated pursuant to the preceding provisions, then, without prejudice to any rights or remedies of the Issuing Lender or any Lender hereunder, all letter of credit fees payable under Section 2.6(b)(i) and (iii) with respect to such Defaulting Lender’s share of the Letter of Credit Exposure shall be payable to the Issuing Lender until such Letter of Credit Exposure is cash collateralized and/or reallocated.

In the event that the Administrative Agent, the Borrower and the Issuing Lender each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then (i) the Letter of Credit Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall be deemed to have purchased at par such of the Revolving Advances or participations in Letters of Credit of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Revolving Advances and Letter of Credit Exposure in accordance with its Pro Rata Share, and (ii) if no Default exists, then any cash collateral posted by the Borrower pursuant to clause (c)(ii) above with respect to such Lender shall be returned to the Borrower.

Section 2.15. Increase in Commitments.

(a) At any time prior to the Business Day immediately preceding the Revolving Maturity Date, the Borrower may effectuate one or more increases in the aggregate 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 existing Lender, to increase its Commitment as such Lender shall so select (an “Increasing Lender”) and, in the case of any Eligible Assignee that is not an existing Lender (an “Additional Lender”), to become a party to this Agreement as a Lender; provided, however, that (i) each such Commitment Increase shall be equal to at least $5,000,000, (ii) all Commitments and Advances provided pursuant to a Commitment Increase shall be available on the same terms as those applicable to the existing Commitments and Advances except as to upfront fees which may be as agreed to between the Borrower and such Increasing Lender or Additional Lender, as the case may be, (iii) the aggregate of all such Commitment Increases

-49-

shall not exceed an amount equal to the sum of $100,000,000, and (iv) such Commitment Increase shall not effect an increase in the aggregate Commitments if the Revolving Maturity Date has occurred. The Borrower shall provide prompt notice of such 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. For the avoidance of doubt, the increase of the aggregate Commitments to $200,000,000 pursuant to the Second Amendment constitutes a Commitment Increase pursuant to this Section 2.15 and no further increases of the aggregate Commitments shall be permitted pursuant to this Section 2.15 after the Second Amendment Effective Date.

(b) The Commitment Increase shall become effective on the date (the “Increase Date”) on or prior to which each of 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/or each Additional Lender, setting forth the Commitments, if any, of each such Increasing Lender and/or Additional Lender and, if applicable, 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 and the Guarantors with respect to such Commitment Increase and such legal opinions as the Administrative Agent may reasonably request, (ii) the funding by each Increasing Lender and Additional Lender of the Revolving Advances to be made by each such Lender to effect the prepayment requirement set forth in Section 2.4(c)(iii), (iii) receipt by the Administrative Agent of a certificate of an authorized officer of the Borrower certifying (A) both before and after giving effect to such Commitment Increase, no Default has occurred and is continuing, (B) 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, and (C) the pro forma compliance with the covenants in Sections 6.16 and 6.17, after giving effect to such Commitment Increase, and (iv) receipt by the Increasing Lender or Additional Lender, as applicable, of all such fees as agreed to between such Increasing Lender and /or Additional Lender and the Borrower.

(c) On such Increase Date, each Lender’s share of the Letter of Credit Exposure and participations in respect of Swing Line Advances on such date shall automatically be deemed to equal such Lender’s Pro Rata Share of such Letter of Credit Obligations and participations in respect of Swing Line Advances (such Pro Rata Share for such Lender to be determined as of the Increase Date in accordance with its Commitment on such date as a percentage of the aggregate Commitments on such date) without further action by any party.

Upon the request of the Administrative Agent at any time, the Secured Parties will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 8.8.

(c) Notwithstanding anything contained in any of the Credit Documents to the contrary, the Credit Parties, the Administrative Agent, and each Secured Party hereby agree that no Secured Party shall have any right individually to realize upon any of the Collateral or to enforce the Guaranty, it being understood and agreed that all powers, rights and remedies hereunder and under the Security Documents may be exercised solely by Administrative Agent on behalf of the Secured Parties in accordance with the terms hereof and the other Credit Documents. By accepting the benefit of the Liens granted pursuant to the Security Documents, each Secured Party not party hereto hereby agrees to the terms of this paragraph (c).

Section 8.9. No Other Duties, etc. Anything herein to the contrary notwithstanding, the Syndication Agent, Co-Documentation Agents, Lead Arranger and Sole Bookrunner listed on the cover page hereof shall not have any powers, duties or responsibilities under this Agreement or any of the other Credit Documents, except in its capacity, as applicable, as the Administrative Agent, a Lender or the Issuing Lender hereunder.

Section 8.10. Flood Laws. The Administrative Agent has adopted internal policies and procedures that address requirements placed on federally regulated lenders under the National Flood Insurance Reform Act of 1994 and related legislation (the “Flood Laws”). Upon request of any Lender, the Administrative Agent will provide to such Lender any documents that the Administrative Agent receives in connection with the Flood Laws. Notwithstanding the foregoing, each Lender and participant is responsible for assuring its own compliance with requirements under Flood Laws.

All representations and warranties contained in this Agreement or made in writing by or on behalf of the Credit Parties in connection herewith shall survive the execution and delivery of this Agreement and the other Credit Documents, the making of the Advances or the issuance of any Letters of Credit and any investigation made by or on behalf of the Lenders, none of which investigations shall diminish any Lender’s right to rely on such representations and warranties. All obligations of the Borrower or any other Credit Party provided for in Sections 2.9, 2.10, 2.12(c), 9.1 and 9.2 and all of the obligations of the Lenders in Section 8.5 shall survive any termination of this Agreement and repayment in full of the Obligations.

Section 9.7. Lender Assignments and Participations.

(a) Each Lender may assign to one or more Eligible Assignees all or a portion of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Advances, its Notes, and its Commitments); provided, however, that (i) each such assignment shall be to an Eligible

-87-

Assignee; (ii) except in the case of an assignment to another Lender or an assignment of all of a Lender’s rights and obligations under this Agreement, any such partial assignment shall be in an amount at least equal to $5,000,000 unless the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents to a lower amount (each such consent not to be unreasonably withheld or delayed); provided that the Borrower shall be deemed to have consented to such lower amount unless it shall have objected thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; (iii) each assignment of a Lender’s rights and obligations with respect to Advances and its Commitments shall be of a constant, and not varying, percentage of all of its rights and obligations under this Agreement as a Lender and the Notes (other than rights of reimbursement and indemnity arising before the effective date of such assignment) and shall be of an equal pro rata share of the Assignor’s interest in the Revolving Advances and Term Advances, and its Commitment; and (iv) the parties to such assignment shall execute and deliver to the Administrative Agent for its acceptance an Assignment and Acceptance, together with any Notes subject to such assignment and the assignor or assignee Lender shall pay a processing fee of $3,500; provided that such processing fee shall not be required for the initial assignments made by Amegy as a Lender in connection with the initial syndication of its Commitments hereunder and such processing fee may be waived at the sole discretion of the Administrative Agent. Upon execution, delivery, and acceptance of such Assignment and Acceptance and payment of the processing fee, the assignee thereunder shall be a party hereto and, to the extent of such assignment, have the obligations, rights, and benefits of a Lender hereunder and the assigning Lender shall, to the extent of such assignment, relinquish its rights and be released from its obligations under this Agreement. Upon the consummation of any assignment pursuant to this Section 9.7, the assignor, the Administrative Agent and the Borrower shall make appropriate arrangements so that, if requested, new Notes are issued to the assignor and the assignee. The assignee shall deliver to the Borrower and the Administrative Agent any applicable forms or certifications in accordance with Section 2.12(e).

(b) The Administrative Agent, acting solely for this purpose as an agent of the Borrower for tax purposes, shall maintain at its address referred to in Section 9.9 a copy of each Assignment and Acceptance delivered to and accepted by it and a register for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amount (and stated interest) of the Advances owing to, each Lender from time to time (the “Register”). The entries in the Register shall be conclusive and binding for all purposes, absent manifest error, and the Credit Parties, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(c) Upon its receipt of an Assignment and Acceptance executed by the parties thereto, together with any Notes subject to such assignment and payment of the processing fee, the Administrative Agent shall, if such Assignment and Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii) record the information contained therein in the Register, and (iii) give prompt notice thereof to the parties thereto.

(d) Each Lender may sell participations to one or more Persons in all or a portion of its rights and/or obligations under this Agreement (including all or a portion of its Commitments or its Advances) provided, however, that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, (iii) the participant shall be entitled to the benefit of the yield protection provisions contained in Sections 2.9 and 2.10 (but with respect to any particular participant, to no greater extent than the Lender that sold the participation to such participant) and the right of set-off contained in Section 7.4, and (iv) the Borrower shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement, and such Lender shall retain the sole right to

-88-

enforce the obligations of the Borrower relating to its Advances and its Notes and to approve any amendment, modification, or waiver of any provision of this Agreement (other than amendments, modifications, or waivers decreasing the amount of principal of or the rate at which interest is payable on such Advances or Notes, extending any scheduled principal payment date or date fixed for the payment of interest on such Advances or Notes, or extending its Commitment). Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Advances or other obligations under the Credit 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 Credit 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. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(e) Notwithstanding any other provision set forth in this Agreement, any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or any other central bank having jurisdiction over such Lender; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(f) Any Lender may furnish any information concerning the Borrower or any of its Subsidiaries in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants), subject, however, to the provisions of the following Section 9.8.

Section 9.8. Confidentiality. The Administrative Agent, the Swing Line Lender, each Issuing Lender, and each Lender (each a “Lending Party”) agree to keep confidential any information furnished or made available to it by any Credit Party pursuant to this Agreement and identified by such Credit Party as proprietary or confidential; provided that nothing herein shall prevent any Lending Party from disclosing such information (a) to any other Lending Party or any Affiliate of any Lending Party, or any officer, director, employee, agent, or advisor of any Lending Party or Affiliate of any Lending Party for purposes of administering, negotiating, considering, processing, implementing, syndicating, assigning, or evaluating the credit facilities provided herein and the transactions contemplated hereby or any Hedging Arrangement (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and will be instructed to keep such information confidential), (b) to any other Person if directly incidental to the administration of the credit facilities provided herein (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and will be instructed to keep such information confidential), (c) as required by any Legal Requirement (with, to the extent permitted by applicable law, prompt notice to the Borrower), (d) upon the order of any court or administrative agency (with, to the extent permitted by applicable law, prompt notice to the Borrower), (e) upon the request or demand of any regulatory agency or authority having jurisdiction or purporting to have jurisdiction over such Lending Party (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (f) that is or becomes available to the public (other than as a result of a breach of this Section by such Lending Party) or that is or becomes available to any Lending Party on a non-confidential basis as a result of a disclosure by any Person other than a Credit Party, (g) in connection with any litigation relating to this Agreement or

-89-

any other Credit Document to which such Lending Party or any of its Affiliates may be a party (with, to the extent permitted by applicable law, prompt notice to the Borrower), (h) to the extent necessary in connection with the exercise of any right or remedy under this Agreement or any other Credit Document, (i) to any actual or proposed participant or Eligible Assignee, in each case, subject to provisions similar to those contained in this Section 9.8 and, in the event such participant or Eligible Assignee is a direct competitor of the Borrower or its Subsidiaries and no Event of Default has occurred and is continuing, with the prior written consent of the Borrower, (j) on a confidential basis to (i) any rating agency in connection with rating the Borrower or its Subsidiaries or the credit facilities provided herein, (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the credit facilities provided herein, or (iii) any credit insurer, and (k) with the consent of the Borrower. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, nothing in this Agreement shall (a) restrict any Lending Party from providing information to any bank or other regulatory or governmental authorities, including the Federal Reserve Board and its supervisory staff; (b) require or permit any Lending Party to disclose to any Credit Party that any information will be or was provided to the Federal Reserve Board or any of its supervisory staff; or (c) require or permit any Lending Party to inform any Credit Party of a current or upcoming Federal Reserve Board examination or any nonpublic Federal Reserve Board supervisory initiative or action. In the event that any of the terms of this Section 9.8 conflict with any non-disclosure agreement executed by a Lending Party prior to the date hereof, then the terms of this Section 9.8 shall govern and control.

Section 9.9. Notices, Etc.

(a) Except as provided in paragraph (b) below, 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 a Credit Party, as specified on Schedule II, if to the Swing Line Lender, the Administrative Agent or the Issuing Lender, at its credit contact specified under its name on Schedule II, and if to any Lender at is credit contact specified in its Administrative Questionnaire. 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, the 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 the Swing Line Lender, such Lender or Issuing Lender, as applicable, verbally or in writing. Notices delivered through electronic communications to the extent provided in paragraph (b) below, shall be effect as provided in said paragraph (b).

(b) Notices and other communications to the Administrative Agent and each Lender hereunder may be delivered or furnished by electronic communication (including e-mail, internet or intranet websites) pursuant to procedures approved by the Administrative Agent; provided that (x) such communication is followed promptly by an original delivered in accordance with paragraph (a) above and (y) the foregoing shall not apply to notices to the Administrative Agent or any Lender pursuant to Article 2 if such person has notified the Borrower that it is incapable of receiving notices under such article by electronic communication. Unless the Administrative Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon sender’s receipt of an acknowledgment from the recipient (such as by the “Return Receipt Requested” function, as available, return e-mail or other written acknowledgment), and (ii) notices or communications posted to an internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (1) of notification that such notice or communication is available and identifying the website address therefor.

-90-

Section 9.10. Usury Not Intended. It is the intent of each Credit Party 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 Credit Parties 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 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 Credit Parties 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 9.11. 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 9.12. Governing Law; Service of Process. This Agreement, the Notes and the other Credit Documents (unless otherwise expressly provided therein) shall be deemed a contract under, and shall be governed by, and construed and enforced in accordance with, the laws of the State of Texas without regard to conflicts of laws principles. 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-

-91-

party accounts), 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 either (i) the Uniform Customs and Practice for Documentary Credits (2007 Revision), International Chamber of Commerce Publication No. 600, or (ii) 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. 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 the Borrower at the address set forth for the Borrower in this Agreement. 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 9.13. Submission to Jurisdiction. Each party hereto 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 each party hereto hereby irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such court. Each party hereto 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 forum to the maintenance of such action or proceeding. Each party hereto 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 Person at its address set forth in this Agreement. Each party hereto hereby 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 the Administrative Agent or any Lender to serve legal process in any other manner permitted by the law or affect the right of the Administrative Agent or any Lender to bring any action or proceeding against any Credit Party 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. Dispute Resolution. This section contains a jury waiver, arbitration clause, and a class action waiver. READ IT CAREFULLY.

This dispute resolution provision shall supersede and replace any prior “Jury Waiver,” “Judicial Reference,” “Class Action Waiver,” “Arbitration,” “Dispute Resolution,” or similar alternative dispute agreement or provision between or among the parties.

JURY TRIAL WAIVER; CLASS ACTION WAIVER. As permitted by applicable law, each party waives their respective rights to a trial before a jury in connection with any Dispute (as “Dispute” is hereinafter defined), and Disputes shall be resolved by a judge sitting without a jury. If a court determines that this provision is not enforceable for any reason and at any time prior to trial of the Dispute, but not later than 30 days after entry of the order determining this provision is unenforceable, the Administrative Agent or any Credit Party shall be entitled to move the court for an order compelling arbitration and staying or dismissing such litigation pending arbitration (“Arbitration Order”). If permitted by applicable law, each party also waives the right to litigate in court or an arbitration proceeding any Dispute as a class action, either as a member of a class or as a representative, or to act as a private attorney general.

-92-

ARBITRATION. If a claim, dispute, or controversy arises with respect to this Agreement, related agreements, or any other agreement or business relationship whether or not related to the subject matter of this Agreement (all of the foregoing, a “Dispute”), and only if a jury trial waiver is not permitted by applicable law or ruling by a court, either party may require that the Dispute be resolved by binding arbitration before a single arbitrator. By agreeing to arbitrate a Dispute, each party gives up any right that party may have to a jury trial, as well as other rights that party would have in court that are not available or are more limited in arbitration, such as the rights to discovery and to appeal.

Arbitration shall be commenced by filing a petition with, and in accordance with the applicable arbitration rules of, JAMS or National Arbitration Forum (“Administrator”) as selected by the initiating party. If the parties agree, arbitration may be commenced by appointment of a licensed attorney who is selected by the parties and who agrees to conduct the arbitration without an Administrator. Disputes include matters (i) relating to a deposit account, application for or denial of credit, enforcement of any of the obligations any party has to another party, compliance with applicable laws and/or regulations, performance or services provided under any agreement by any party, (ii) based on or arising from an alleged tort, or (iii) involving any party’s employees, agents, affiliates, or assigns. However, Disputes do not include the validity, enforceability, meaning, or scope of this arbitration provision and such matters may be determined only by a court. If a third party is a party to a Dispute, each party consents to including the third party in the arbitration proceeding for resolving the Dispute with the third party. Venue for the arbitration proceeding shall be at a location determined by mutual agreement of the parties or, if no agreement, in Houston, Texas.

If a court orders arbitration of a Dispute, the party to the Dispute that did not seek the Arbitration Order shall commence arbitration. The party that sought the Arbitration Order may commence arbitration, but shall have no obligation to do so, and shall not in any way be adversely prejudiced by initiating or participating in litigation or electing not to commence arbitration. The arbitrator shall (i) hear and rule on appropriate dispositive motions for judgment on the pleadings, for failure to state a claim, or for full or partial summary judgment; (ii) render a decision and any award applying applicable law; (iii) give effect to any limitations period in determining any Dispute or defense; (iv) enforce the doctrines of compulsory counterclaim, res judicata, and collateral estoppel, if applicable; (v) with regard to motions and the arbitration hearing, apply rules of evidence governing civil cases; and (vi) apply the law of the state specified in the agreement giving rise to the Dispute. Filing of a petition for arbitration shall not prevent any party from (i) seeking and obtaining from a court of competent jurisdiction (notwithstanding ongoing arbitration) provisional or ancillary remedies including but not limited to injunctive relief, property preservation orders, foreclosure, eviction, attachment, replevin, garnishment, and/or the appointment of a receiver, (ii) pursuing non-judicial foreclosure, or (iii) availing itself of any self-help remedies such as setoff and repossession. The exercise of such rights shall not constitute a waiver of the right to submit any Dispute to arbitration.

Judgment upon an arbitration award may be entered in any court having jurisdiction, except that, if the arbitration award exceeds $4,000,000, any party shall be entitled to a de novo appeal of the award before a panel of three arbitrators. To allow for such appeal, if the award (including Administrator, arbitrator, and attorney’s fees and costs) exceeds $4,000,000, the arbitrator will issue a written, reasoned decision supporting the award, including a statement of authority and its application to the Dispute. A request for de novo appeal must be filed with the arbitrator within 30 days following the date of the arbitration award; if such a request is not made within that time period, the arbitration decision shall become final and binding. On appeal, the arbitrators shall review the award de novo, meaning that they shall reach their own findings of fact and conclusions of law rather than deferring in any manner to the original arbitrator. Appeal of an arbitration award shall be pursuant to the rules of the Administrator or, if the Administrator has no such rules, then the JAMS arbitration appellate rules shall apply.
