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

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

(v) if a Borrower shall fail to select the duration or continuation of any Interest Period for any Eurodollar Rate Advances in accordance with the provisions contained in the definition of “Interest Period” in Section 1.01 and paragraph (b) above, the Administrative Agent shall forthwith so notify the Borrower Representative and the Lenders and such Advances shall be made available to the applicable Borrower, as designated by the Borrower Representative, on the date of the Borrowing comprised of such Advances as Reference Rate Advances or, if existing Eurodollar Rate Advances, shall Convert into Reference Rate Advances.

(d) Notices Irrevocable. Each Notice of Borrowing and Notice of Conversion or Continuation shall be irrevocable and binding on each Borrower. In the case of any Borrowing for which the related Notice of Borrowing specifies is to be comprised of Eurodollar Rate Advances, the Borrowers shall indemnify each Lender against any loss, out-of-pocket cost, or expense incurred by such Lender as a result of any failure by any Borrower to fulfill on or before the date specified in such Notice of Borrowing for such Borrowing the applicable conditions set forth in Article III including, without limitation, any loss, cost, or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund the Advance to be made by such Lender as part of such Borrowing when such Advance, as a result of such failure, is not made on such date.

(e) Administrative Agent Reliance. Unless the Administrative Agent shall have received notice from a Lender before the date of any Borrowing that such Lender shall not make available to the Administrative Agent such Lender’s Pro Rata Share of a 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 paragraph (a) of this Section 2.03 and the Administrative Agent may, in reliance upon such assumption, make available to the applicable Borrower, as designated by the Borrower Representative, 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 Borrowers 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 a Borrower until the date such amount is repaid to the Administrative Agent, at (i) in the case of the Borrowers, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Lender, the Federal Funds Rate for such day. 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) Lender Obligations Several. The failure of any Lender to make the Advance to be made by it as part of any Borrowing shall not relieve any other Lender of its obligation, if any, to make its Advance on the date of such Borrowing. No Lender shall be responsible for the failure of any other Lender to make the Advance to be made by such other Lender on the date of any Borrowing.

Section 2.04 Reduction of the Commitments.

(a) Optional. The Borrowers shall have the right, upon at least three Business Days’ irrevocable notice from the Borrower Representative to the Administrative Agent, to terminate in whole or reduce ratably in part the unused portion of the Commitments; provided that, in each case, each partial reduction shall be in the aggregate amount of $10,000,000 or in integral multiples of $5,000,000 in excess thereof.

(b) Mandatory. If at any time the Borrowing Base is less than an amount equal to five (5) times the amount of the aggregate Commitments, the Commitments shall automatically and without the giving of any notice or other condition, be reduced ratably to the extent necessary to cause such Commitments, as so reduced, to equal no more than 20% of the Borrowing Base then in effect. In addition, if either of the Borrowers (i) sells, leases, transfers, assigns, farms-out, conveys or otherwise disposes of any of its Property in a transaction not permitted by Section 6.04, (ii) creates, incurs, assumes or otherwise becomes liable for any Debt in a transaction not permitted by Section 6.02, or (iii) receives Extraordinary Proceeds, then the aggregate amount of the Commitments shall be reduced by an amount equal to the net sales proceeds, debt issuance proceeds, or Extraordinary Proceeds, as applicable, received by the Borrowers.

(c) Application. Any reduction and termination of the Commitments pursuant to this Section 2.04 (whether voluntary or mandatory) shall be applied ratably to each Lender’s Commitments and shall be permanent, with no obligation of the Lenders to reinstate such Commitments.

Section 2.05 Prepayment of Advances; Deposits Into Cash Collateral Account.

(a) Optional. The Borrowers may prepay the Advances, after giving by 1:00 p.m. (Central Standard or Daylight Savings Time) (i) in the case of Eurodollar Rate Advances, at least three Business Days’ or (ii) in the case of Reference Rate Advances, same Business Day’s, irrevocable prior written notice from the Borrower Representative to the Administrative Agent stating the proposed date and aggregate principal amount of such prepayment. If any such notice

is given, the Borrowers shall prepay the Advances 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 2.12 as a result of such prepayment being made on such date; provided, however, that each partial prepayment with respect to: (a) any amounts prepaid in respect of Eurodollar Rate Advances shall be applied to Eurodollar Rate Advances comprising part of the same Borrowing; (b) any prepayments made in respect of Reference Rate Advances shall be made in a minimum amounts of $100,000 and in integral multiples of $100,000 in excess thereof; and (c) any prepayments made in respect of any Borrowing comprised of Eurodollar Rate Advances shall be made in an aggregate principal amount of at least $500,000 and in integral multiples of $100,000 in excess thereof, and in an aggregate principal amount such that after giving effect thereto such Borrowing shall have a remaining principal amount outstanding with respect to such Borrowing of at least $500,000. Full prepayments of any Borrowing are permitted without restriction of amounts.

(b) Mandatory. If the aggregate Commitments are reduced pursuant to Section 2.04 (whether voluntarily or as the result of a mandatory reduction) and after giving effect to such reduction the sum of (A) the aggregate outstanding amount of the Advances plus (B) the excess, if any, of the Letter of Credit Exposure over the amount held in the Cash Collateral Account at such time ever exceeds the aggregate Commitments (such excess being referred to herein as a “deficiency”), the Borrower Representative shall after receipt of written notice from the Administrative Agent regarding such deficiency, deliver to the Administrative Agent within ten days of receipt of such notice from the Administrative Agent, a written response indicating which of the following actions (or combination thereof) the Borrowers intend to take to remedy such deficiency (and the failure of the Borrower Representative to deliver such election notice or the Borrowers to perform the action chosen to remedy such deficiency shall constitute an Event of Default):

(i) prepay the Advances to the extent of the deficiency set forth in such notice or, if the Advances have been repaid in full, make deposits into the Cash Collateral Account to provide cash collateral for the Letter of Credit Exposure such that the deficiency is cured within 30 days after the date such deficiency notice is received by the Borrower Representative from the Administrative Agent; or

(ii) pledge as Collateral for the Obligations additional Oil and Gas Properties acceptable to the Administrative Agent and each of Lenders such that the deficiency is cured within 30 days after the date such written response is sent by the Borrower Representative to the Administrative Agent.

(c) Each prepayment pursuant to this Section 2.05(b) shall be accompanied by accrued interest on the amount prepaid to the date of such prepayment and amounts, if any, required to be paid pursuant to Section 2.12 as a result of such prepayment being made on such date. Each prepayment under Section 2.05(b)(i)(1) shall be applied to the Advances as determined by the Administrative Agent and agreed to by the Lenders in their sole discretion.

(d) Illegality. If any Lender shall notify the Administrative Agent and the Borrower Representative that, on or after the date hereof, 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 Lending Office to perform its obligations under this Agreement to maintain any Eurodollar Rate Advances of such Lender then outstanding hereunder, (i) the Borrowers shall, no later than 2:00 p.m. (Central Standard or Daylight Savings Time) (A) if not prohibited by law, on the last day of the Interest Period for each outstanding Eurodollar Rate Advance made by such Lender or (B) if required by such notice, on the second Business Day following its receipt of such notice, prepay all of the Eurodollar Rate Advances made by 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 2.12 as a result of such prepayment being made on such date, (ii) such Lender shall simultaneously make a Reference Rate Advance to the Borrowers on such date in an amount equal to the aggregate principal amount of the Eurodollar Rate Advances prepaid to such Lender, and (iii) the right of the Borrowers to select Eurodollar Rate Advances from such Lender for any subsequent Borrowing shall be suspended until such Lender gives notice referred to above shall notify the Administrative Agent that the circumstances causing such suspension no longer exist.

(e) No Additional Right; Ratable Prepayment. No Borrower shall have the right to prepay any principal amount of any Advance except as provided in this Section 2.05, and all notices given pursuant to this Section 2.05 shall be irrevocable and binding upon each Borrower. Each payment of any Advance pursuant to this Section 2.05 shall be made in a manner such that all Advances comprising part of the same Borrowing are paid in whole or ratably in part.

Section 2.06 Repayment of Advances. The Borrowers shall repay to the Administrative Agent for the ratable benefit of the Lenders the outstanding principal amount of each Advance, together with any accrued interest thereon, on the Maturity Date or such earlier date pursuant to Section 7.02 or Section 7.03.

Section 2.07 Letters of Credit.

(a) Commitments for Letters of Credit. From time to time from the date of this Agreement until 30 days prior to the Maturity Date at the request of the Borrower Representative, the Issuing Lender shall, on the terms and conditions hereinafter set forth, issue, increase, or extend the Expiration Date of, Letters of Credit for the account of the Borrower on any Business Day. No Letter of Credit will be issued, increased, or extended:

(i) if such issuance, increase, or extension would cause the Letter of Credit Exposure to exceed the lesser of (A) $5,000,000 and (B) the lesser of (1) the aggregate Commitments at such time and (2) the Borrowing Base in effect at such time minus, in each case, under this clause (B) the sum of the aggregate outstanding principal amount of all Advances at such time;

(ii) if such Letter of Credit has an Expiration Date later than the earlier of (A) one year after the date of issuance thereof (or, in the case of any extension thereof, one year after the date of such extension) and (B) 30 days prior to the Maturity Date;

(iii) unless the Letter of Credit Documents are in form and substance acceptable to the Issuing Lender in its sole discretion;

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

(v) unless the Borrower Representative has delivered to the Issuing Lender a completed and executed Letter of Credit Application; and

(vi) unless such Letter of Credit is governed by (A) the Uniform Customs and Practice for Documentary Credits (2007 Revision) or the Uniform Customs and Practice for Documentary Credits (2006 Revision), or (B) the International Standby Practices (ISP98) or 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.

If the terms of any Letter of Credit Application referred to in the foregoing clause (v) conflicts with the terms of this Agreement, the terms of this Agreement shall control.

(b) Participations. Upon the date of the issuance or increase of a Letter of Credit, 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 telephone, or facsimile of each Letter of Credit issued, increased, or extended or converted and the actual dollar amount of such Lender’s participation in such Letter of Credit.

(c) Issuing. Each Letter of Credit shall be issued, increased, or extended pursuant to a Letter of Credit Application (or by telephone notice promptly confirmed in writing by a Letter of Credit Application), given by the Borrower Representative not later than 2:00 p.m. (Central Standard or Daylight Savings Time) on the fifth Business Day before the date of the proposed issuance, increase, or extension of such Letter of Credit, and the Issuing Lender shall give to each other Lender prompt notice thereof by telex, telephone, or facsimile. Each Letter of Credit Application shall be delivered by facsimile or by mail specifying the information required therein; provided that if such Letter of Credit Application is delivered by facsimile, the Borrower Representative shall follow such facsimile with an original by mail. After the Issuing Lender’s receipt of such Letter of Credit Application (by facsimile or by mail) and upon fulfillment of the applicable conditions set forth in Article III, the Issuing Lender shall issue, increase, or extend such Letter of Credit for the account of any Borrower. Each Letter of Credit Application shall be irrevocable and binding on each Borrower.

(d) Reimbursement.

(i) The Borrowers hereby agree to pay to the Issuing Lender an amount equal to any amount paid by the Issuing Lender under any Letter of Credit, which amount shall be due and payable on demand given by the Issuing Lender to the Borrower Representative. In the event the Issuing Lender makes a payment pursuant to a request for draw presented under a

Letter of Credit and such payment is not promptly reimbursed by the Borrowers upon demand, the Issuing Lender shall give the Administrative Agent notice of the Borrowers’ failure to make such reimbursement and the Administrative Agent shall promptly notify each Lender of the amount necessary to reimburse the Issuing Lender. Upon such notice from the Administrative Agent, each Lender shall promptly reimburse the Issuing Lender for such Lender’s Pro Rata Share of such amount, and such reimbursement shall be deemed for all purposes of this Agreement to be an Advance to the Borrowers transferred at the Borrowers’ request to the Issuing Lender. If such reimbursement is not made by any Lender to the Issuing Lender on the same day on which the Administrative Agent notifies such Lender to make reimbursement to the Issuing Lender hereunder, such Lender shall pay interest on its Pro Rata Share thereof to the Issuing Lender at a rate per annum equal to the Federal Funds Rate. Each Borrower hereby unconditionally and irrevocably authorizes, empowers, and directs the Administrative Agent and the Lenders to record and otherwise treat such reimbursements to the Issuing Lender as Reference Rate Advances under a Borrowing made at the request of the Borrowers to reimburse the Issuing Lender which have been transferred to the Issuing Lender at the Borrowers’ request.

(ii) Each Lender’s obligation to make Advances or to purchase and fund risk participations in Letters of Credit pursuant to this Section 2.07(d) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Issuing Lender, any Borrower, or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrowers to pay the Reimbursement Obligations together with interest as provided herein. Nothing herein is intended to release the Borrowers’ obligations under any Letter of Credit Application, but only to provide an additional method of payment therefor. The making of any Borrowing under Section 2.07(d)(i) shall not constitute a cure or waiver of any Default or Event of Default, other than the payment Default or Event of Default which is satisfied by the application of the amounts deemed advanced hereunder, caused by a Borrower’s failure to comply with the provisions of this Agreement or the Letter of Credit Application.

(e) Obligations Unconditional. The obligations of the Borrowers 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, including, without limitation, the following circumstances:

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

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

(iii) the existence of any claim, set-off, defense, or other right which any Borrower 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, or any other Person, 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;

(v) payment by the Issuing Lender under such Letter of Credit against presentation of a draft or certificate which does not strictly 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 Borrowers in connection with the Letters of Credit or the Borrowers’ rights under Section 2.07(f) below.

(f) Liability of Issuing Lender. Each 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 Related Parties 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 strictly comply with the terms of a Letter of Credit, including failure of any documents to bear any reference or adequate reference to the relevant Letter of Credit; or

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

except that the Borrowers shall have a claim against the Issuing Lender, and the Issuing Lender shall be liable to the Borrowers, to the extent of any direct, as opposed to consequential, damages suffered by the Borrowers which the Borrowers prove were caused by 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. 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.

(g) Cash Collateral Account.

(i) If the Borrowers are required to deposit funds in the Cash Collateral Account pursuant to terms hereof, then the Borrowers and the Issuing Lender shall establish the Cash Collateral Account and the Borrowers shall execute any documents and agreements, including the Issuing Lender’s standard form assignment of deposit accounts, that the Issuing Lender requests in connection therewith to establish the Cash Collateral Account and grant the Administrative Agent a first priority security interest in such account and the funds therein. Each Borrower hereby pledges to the Administrative Agent and grants to the Administrative Agent for the benefit of the Secured Parties 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 Obligations.

(ii) So long as no Default or Event of Default exists, (x) the Administrative Agent may apply the funds held in the Cash Collateral Account only to the reimbursement of any Letter of Credit Obligations, and (y) the Issuing Lender shall release to the applicable Borrower as designated by, and at the Borrower Representative’s written request, any funds held in the Cash Collateral Account in an amount up to but not exceeding the excess, if any (immediately prior to the release of any such funds), of the total amount of funds held in the Cash Collateral Account over the Letter of Credit Exposure. During the existence of any Default, the Administrative Agent may apply any funds held in the Cash Collateral Account to the Obligations in accordance with Section 7.06, regardless of the Letter of Credit Exposure that may remain outstanding.

(iii) 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.

(h) Letters of Credit Issued for Subsidiaries. Notwithstanding that a Letter of Credit issued or outstanding hereunder is in support of any obligations of, or is for the account of, a Subsidiary of a Borrower, the Borrowers shall be obligated to reimburse the Issuing Lender hereunder for any and all drawings under such Letter of Credit issued under the either Facility by the Issuing Lender. Each Borrower hereby acknowledges that the issuance of Letters of Credit for the account of any of Subsidiary of a Borrower inures to the benefit of such Borrower, and that such Borrower’s business derives substantial benefits from the businesses of such Subsidiaries.

Section 2.08 Fees.

(a) Commitment Fees. The Borrowers agree to pay to the Administrative Agent for the account of each Lender a commitment fee at a per annum rate equal to 0.50% on the daily Unused Commitment Amount of such Lender from the date of this Agreement until the Commitment Termination Date. The commitment fees shall be due and payable quarterly in arrears on the last day of each March, June, September, and December commencing on September 30, 2008 and continuing thereafter through and including the Commitment Termination Date.

(b) Letter of Credit Fees.

(i) The Borrowers agree to pay (a) to the Administrative Agent for the pro rata benefit of the Lenders a per annum letter of credit fee for each Letter of Credit issued hereunder in an amount equal to the greater of (1) 2.00% times the daily maximum amount available to be drawn under such Letter of Credit and (2) $500, and (b) to the Issuing Lender, a fronting fee for each Letter of Credit equal to 0.125% times the maximum amount available to be drawn under such Letter of Credit. Each such fee shall be computed on a quarterly basis in arrears and be due and payable on the last day of each March, June, September, and December commencing September 30, 2008.

(ii) The Borrowers also agree to pay to the Issuing Lender such other usual and customary fees associated with any transfers, amendments, drawings, negotiations or reissuances of any Letters of Credit.

Section 2.09 Interest. The Borrowers shall pay interest on the unpaid principal amount of each Advance made by each Lender from the date of such Advance until such principal amount shall be paid in full as follows:

(a) Reference Rate Advances. If such Advance is a Reference Rate Advance, the Borrowers shall pay interest on the unpaid principal amount of such Advances at a rate per annum equal at all times to the Adjusted Reference Rate in effect from time to time payable monthly in arrears on the last day of each calendar month and on the date such Reference Rate Advance shall be paid in full; provided that, if a Default or Event of Default shall have occurred and be continuing, such interest shall accrue at a rate per annum equal at all times to the Adjusted Reference Rate plus 4% per annum.

(b) Eurodollar Rate Advances. If such Advance is a Eurodollar Rate Advance, a rate per annum equal at all times during the Interest Period for such Advance to the Eurodollar Rate for such Interest Period plus 2.00%; provided that, if a Default or Event of Default shall have occurred and be continuing, such interest shall accrue at a rate per annum equal at all times to the Adjusted Reference Rate plus 4% per annum.

(c) Additional Interest on Eurodollar Rate Advances. The Borrowers shall pay to each Lender, so long as any such Lender shall be required under regulations of the Federal Reserve Board to maintain reserves with respect to liabilities or assets consisting of or including Eurocurrency Liabilities, additional interest on the unpaid principal amount of each Eurodollar Rate Advance of such Lender, from the effective date of such Advance until such principal amount is paid in full, at an interest rate per annum equal at all times to the remainder obtained by subtracting (i) the Eurodollar Rate for the Interest Period for such Advance from (ii) the rate obtained by dividing such Eurodollar Rate by a percentage equal to 100% minus the Eurodollar Rate Reserve Percentage of such Lender for such Interest Period, payable on each date on which interest is payable on such Advance. Such additional interest payable to any Lender shall be determined by such Lender and notified to the Borrower Representative through the

Administrative Agent (such notice to include the calculation of such additional interest, which calculation shall be conclusive in the absence of manifest error).

(d) Usury Recapture.

(i) If, with respect to any Lender or the Issuing Lender, the effective rate of interest contracted for under the Loan Documents, including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under the Loan Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by such Lender or Issuing Lender, as applicable, hereunder shall bear interest at a rate which would make the effective rate of interest for such Lender or Issuing Lender, as applicable, under the Loan Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the “Lost Interest”) has been recaptured by such Lender or Issuing Lender, as applicable.

(ii) If, when the loans and reimbursement obligations made hereunder are repaid in full, the Lost Interest has not been fully recaptured by such Lender or Issuing Lender, as applicable, pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans and other credit extensions made hereunder by such Lender or Issuing Lender, as applicable, the interest rates charged under Section 2.09 hereunder shall be retroactively increased such that the effective rate of interest under the Loan Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the preceding sentence and, to the extent allowed by law, the Borrowers shall pay to such Lender or Issuing Lender, as applicable, the amount of the Lost Interest remaining to be recaptured by such Lender or Issuing Lender, as applicable.

(iii) NOTWITHSTANDING THE FOREGOING OR ANY OTHER TERM IN THIS AGREEMENT AND THE LOAN DOCUMENTS TO THE CONTRARY, IT IS THE INTENTION OF EACH LENDER, THE ISSUING LENDER AND THE BORROWERS TO CONFORM STRICTLY TO ANY APPLICABLE USURY LAWS. ACCORDINGLY, IF ANY LENDER OR THE ISSUING LENDER CONTRACTS FOR, CHARGES, OR RECEIVES ANY CONSIDERATION WHICH CONSTITUTES INTEREST IN EXCESS OF THE MAXIMUM RATE, THEN ANY SUCH EXCESS SHALL BE CANCELED AUTOMATICALLY AND, IF PREVIOUSLY PAID, SHALL AT SUCH LENDER’S OR THE ISSUING LENDER’S OPTION, AS APPLICABLE, BE APPLIED TO THE OUTSTANDING AMOUNT OF THE LOANS MADE HEREUNDER BY SUCH LENDER OR REIMBURSEMENT OBLIGATIONS DUE HEREUNDER, AS APPLICABLE, OR BE REFUNDED TO THE BORROWERS.

Section 2.10 Payments and Computations.

(a) Payment Procedures. The Borrowers shall make each payment under this Agreement and under the Notes not later than 2:00 p.m. (Central Standard or Daylight Savings Time) on the day when due in Dollars to the Administrative Agent at its Lending Office (or such other location as the Administrative Agent shall designate in writing to the Borrower Representative) in same day funds without deduction, setoff, or counterclaim of any kind. The

Administrative Agent shall promptly thereafter 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, the Issuing Lender, or a specific Lender pursuant to Section 2.08(c), Section 2.09(c), Section 2.09(d), Section 2.12, Section 2.13, Section 2.14, Section 9.05, or Section 10.07, but after taking into account payments effected pursuant to Section 7.04) in accordance with each Lender’s Pro Rata Share to the Lenders for the account of their respective Lending Offices, and like funds relating to the payment of any other amount payable to any Lender or the Issuing Lender to such Lender or Issuing Lender for the account of its Lending Office, in each case to be applied in accordance with the terms of this Agreement.

(b) Computations. All computations of interest based on the Reference Rate and of commitment fees shall be made by the Administrative Agent on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate and the Federal Funds Rate and Letter of Credit 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 interest rate or fee shall be conclusive and binding for all purposes, absent manifest error.

(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, however, that if such extension would cause payment of interest on or principal of Eurodollar Rate Advances to be made in the next following calendar month, such payment shall be made on the next preceding Business Day.

(d) Administrative Agent Reliance. Unless the Administrative Agent shall have received written notice from the Borrower Representative prior to the date on which any payment is due to the Lenders that the Borrowers shall not make such payment in full, the Administrative Agent may assume that the Borrowers have made such payment in full to the Administrative Agent on such date and the Administrative Agent may, in reliance upon such assumption, cause to be distributed to each Lender on such date an amount equal to the amount then due such Lender. If and to the extent the Borrowers shall not have so made such payment in full to the Administrative Agent, each Lender shall repay to the Administrative Agent forthwith on demand such amount distributed to such Lender, together with interest, for each day from the date such amount is distributed to such Lender until the date such Lender repays such amount to the Administrative Agent, at the Federal Funds Rate for such day.

Section 2.11 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 or Letter of Credit Obligations made by it in excess of its Pro Rata Share of payments on account of the Advances or Letter of Credit Obligations obtained by all the Lenders, such Lender shall notify the Administrative Agent and forthwith purchase from the other Lenders such participations in the Advances made by them or Letter of Credit Obligations held by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be

rescinded and such Lender shall repay to the purchasing Lender the purchase price to the extent of such Lender’s ratable share (according to the proportion of (a) the amount of the participation sold by such Lender to the purchasing Lender as a result of such excess payment to (b) the total amount of such excess payment) of such recovery, together with an amount equal to such Lender’s ratable share (according to the proportion of (i) the amount of such Lender’s required repayment to the purchasing Lender to (ii) the total amount of all such required repayments to the purchasing Lender) of any interest or other amount paid or payable by the purchasing Lender in respect of the total amount so recovered. The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.11 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 Borrowers in the amount of such participation.

Section 2.12 Breakage Costs. If (a) any payment of principal of any Eurodollar Rate Advance is made other than on the last day of the Interest Period for such Advance, whether as a result of any payment pursuant to Section 2.05, the acceleration of the maturity of the Notes pursuant to Article VII, or otherwise, or (b) the Borrowers fail to make a principal or interest payment with respect to any Eurodollar Rate Advance on the date such payment is due and payable, the Borrowers shall, within 10 days of any written demand (which written demand shall include a calculation of the losses, costs and expenses referred to below) sent by any Lender to the Borrower Representative through the Administrative Agent, pay to the Administrative Agent for the account of such Lender any amounts required to compensate such Lender for any additional losses, out-of-pocket costs or expenses which it may reasonably incur as a result of such payment or nonpayment, including, without limitation, any loss (but excluding loss of anticipated profits), cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Advance.

Section 2.13 Increased Costs.

(a) Eurodollar Rate Advances. If, due to either (i) the introduction of or any change (other than any change by way of imposition or increase of reserve requirements included in the Eurodollar Rate Reserve Percentage) in or in the interpretation of any law or regulation or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding, or maintaining Eurodollar Rate Advances, then the Borrowers shall from time to time, upon demand by such Lender to the Borrower Representative (with a copy of such demand to the Administrative Agent), immediately pay to the Administrative Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost; provided, however, that the Borrowers shall not be obligated for the payment of any such additional amounts to the extent such costs accrued more than 180 days prior to the date the Borrower Representative was given such demand. A certificate as to the amount of such increased cost and detailing the calculation of such cost submitted to the Borrower Representative and the Administrative Agent by such Lender shall be conclusive and binding for all purposes, absent manifest error.

(b) Capital Adequacy. If any Lender or the Issuing Lender determines in good faith, on or after the date hereof, that compliance with any law or regulation or any guideline or request

from any central bank or other Governmental Authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by such Lender or the Issuing Lender or any corporation controlling such Lender or the Issuing Lender and that the amount of such capital is increased by or based upon the existence of such Lender’s commitment to lend or the Issuing Lender’s commitment to issue the Letters of Credit and other commitments of this type, then, upon 30 days’ prior written notice by such Lender or the Issuing Lender to the Borrower Representative (with a copy of any such demand to the Administrative Agent), the Borrowers shall immediately pay to the Administrative Agent for the account of such Lender or to the Issuing Lender, as the case may be, from time to time as specified by such Lender or the Issuing Lender, additional amounts sufficient to compensate such Lender or the Issuing Lender, in light of such circumstances, (i) with respect to such Lender, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of such Lender’s commitment to lend under this Agreement and (ii) with respect to the Issuing Lender, to the extent that the Issuing Lender reasonably determines such increase in capital to be allocable to the issuance or maintenance of the Letters of Credit. A certificate as to such amounts and detailing the calculation of such amounts submitted to the Borrower Representative by such Lender or the Issuing Lender shall be conclusive and binding for all purposes, absent manifest error.

(c) Letters of Credit. If any change in any law or regulation or in the interpretation thereof by any court or administrative or Governmental Authority charged with the administration thereof shall either (i) impose, modify, or deem applicable any reserve, special deposit, or similar requirement against letters of credit issued by, or assets held by, or deposits in or for the account of, the Issuing Lender or (ii) impose on the Issuing Lender any other condition regarding the provisions of this Agreement relating to the Letters of Credit or any Letter of Credit Obligations, and the result of any event referred to in the preceding clause (i) or (ii) shall be to increase the cost to the Issuing Lender of issuing or maintaining any Letter of Credit (which increase in cost shall be determined by the Issuing Lender’s reasonable allocation of the aggregate of such cost increases resulting from such event), then, upon demand by the Issuing Lender to the Borrower Representative, the Borrowers shall pay to the Issuing Lender, from time to time as specified by the Issuing Lender, additional amounts which shall be sufficient to compensate the Issuing Lender for such increased cost; provided, however, that the Borrowers shall not be obligated for the payment of any such additional amounts to the extent such costs accrued more than 180 days prior to the date the Borrower Representative was given such demand. A certificate as to such increased cost incurred by the Issuing Lender, as a result of any event mentioned in clause (i) or (ii) above, and detailing the calculation of such increased costs submitted by the Issuing Lender to the Borrower Representative, shall be conclusive and binding for all purposes, absent manifest error.

Section 2.14 Taxes.

(a) No Deduction for Certain Taxes. Any and all payments by any Borrower shall be made, in accordance with Section 2.10, 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 each Lender, the Issuing Lender, and the Administrative Agent, taxes imposed on its income, and franchise taxes imposed on it by the jurisdiction under the laws of which such Lender, Issuing Lender or Administrative Agent (as the

case may be) is organized, or the jurisdiction of such Person’s Lending Office, or any political subdivision of such jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If any Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable to any Lender, the Issuing Lender, or the Administrative Agent, (A) 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 2.14), such Lender, the Issuing Lender, or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; provided, however, that if a Borrower’s obligation to deduct or withhold Taxes is caused solely by such Lender’s, the Issuing Lender’s, or the Administrative Agent’s failure to provide the forms described in paragraph (d) of this Section 2.14 and such Lender, the Issuing Lender, or the Administrative Agent could have provided such forms, no such increase shall be required; (B) the Borrowers shall make such deductions; and (C) the Borrowers shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Legal Requirement.

(b) Other Taxes. In addition, the Borrowers agree 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 or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes, or the other Loan Documents (hereinafter referred to as “Other Taxes”).

(c) Indemnification. EACH BORROWER INDEMNIFIES EACH LENDER, THE ISSUING LENDER AND THE ADMINISTRATIVE AGENT FOR THE FULL AMOUNT OF TAXES OR OTHER TAXES (INCLUDING, WITHOUT LIMITATION, ANY TAXES OR OTHER TAXES IMPOSED BY ANY JURISDICTION ON AMOUNTS PAYABLE UNDER THIS SECTION 2.14) PAID BY SUCH LENDER, THE ISSUING LENDER OR THE ADMINISTRATIVE AGENT (AS THE CASE MAY BE) AND ANY LIABILITY (INCLUDING INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED. EACH PAYMENT REQUIRED TO BE MADE BY THE BORROWERS IN RESPECT OF THIS INDEMNIFICATION SHALL BE MADE TO THE ADMINISTRATIVE AGENT FOR THE BENEFIT OF ANY PARTY CLAIMING SUCH INDEMNIFICATION WITHIN 30 DAYS FROM THE DATE THE BORROWER REPRESENTATIVE RECEIVES WRITTEN DEMAND THEREFOR FROM THE ADMINISTRATIVE AGENT ON BEHALF OF ITSELF AS ADMINISTRATIVE AGENT, FROM THE ISSUING LENDER OR FROM ANY SUCH LENDER. IF ANY LENDER, THE ADMINISTRATIVE AGENT OR THE ISSUING LENDER RECEIVES A REFUND IN RESPECT OF ANY TAXES PAID BY A BORROWER UNDER THIS PARAGRAPH (C), SUCH LENDER, THE ADMINISTRATIVE AGENT OR THE ISSUING LENDER, AS THE CASE MAY BE, SHALL PROMPTLY PAY TO THE BORROWER REPRESENTATIVE SUCH BORROWER’S SHARE OF SUCH REFUND.

(d) Foreign Lender Withholding Exemption. Each Lender and Issuing Lender that is not incorporated under the laws of the United States of America or a state thereof agrees that, at the time or times prescribed by applicable law and from time to time as reasonably requested in writing by the Borrower Representative, it shall deliver to the Borrower Representative and the

Administrative Agent (i) two duly completed copies of United States Internal Revenue Service Form W8-ECI or W8-BEN or successor applicable form, as the case may be, certifying in each case that such Lender is entitled to receive payments under this Agreement and the Notes payable to it, without deduction or withholding of any United States federal income taxes, (ii) if applicable, an Internal Revenue Service Form W-8 or W-9 or successor applicable form, as the case may be, to establish an exemption from United States backup withholding tax, and (iii) any other certification, identification, information or documentation which is necessary or required under an applicable tax treaty or otherwise by law to reduce or eliminate any withholding tax. Each Lender and Issuing Lender which delivers to the Borrower Representative and the Administrative Agent a Form ▇▇-▇▇▇, ▇▇-▇▇▇, ▇-▇ or W-9 pursuant to the next preceding sentence further undertakes to deliver to the Borrower Representative and the Administrative Agent two further copies of such letter and Form W8-ECI, ▇▇-▇▇▇, ▇-▇ or W-9, or successor applicable forms, or other applicable certification, as the case may be, on or before the date that any such form or certification expires or becomes obsolete or after the occurrence of any event requiring a change in the most recent form or other certification previously delivered by it to the Borrower Representative and the Administrative Agent, and such extensions or renewals thereof as may reasonably be requested by the Borrower Representative and the Administrative Agent certifying in the case of a Form W8-ECI or W8-BEN that such Lender or Issuing Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes. If an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any delivery required by the preceding sentence would otherwise be required which renders all such forms inapplicable or which would prevent any Lender or Issuing Lender from duly completing and delivering any such letter or form with respect to it and such Lender or Issuing Lender advises the Borrower Representative and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax, and in the case of a Form W-8 or W-9, establishing an exemption from United States backup withholding tax, such Lender or Issuing Lender shall not be required to deliver such letter or forms. The Borrowers shall withhold tax at the rate and in the manner required by the laws of the United States with respect to payments made to a Lender failing to timely provide the requisite Internal Revenue Service forms.

(e) Evidence of Payments. As soon as practicable after any payment of Taxes, Other Taxes or any taxes which are paid pursuant to clause (c) above by any Borrower to a Governmental Authority, such Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

Section 4.11 Taxes.

(a) Reports and Payments. All Returns (as defined below in clause (c) of this Section 4.11) required to be filed by or on behalf of any Borrower or any member of the Controlled Group (hereafter collectively called the “Tax Group”) have been duly filed on a timely basis or appropriate extensions have been obtained and such Returns are and will be true, complete and correct in all material respects, except where the failure to so file would not be reasonably expected to cause a Material Adverse Change; and all Taxes shown to be payable on the Returns or on subsequent assessments with respect thereto will have been paid in full on a timely basis, and no other Taxes will be payable by the Tax Group with respect to items or periods covered by such Returns, except in each case to the extent of (i) reserves reflected in the Combined Initial Financial Statements, the Combined Interim Financial Statements or financial statements of any Borrower delivered to the Administrative Agent pursuant to this Agreement, or (ii) Taxes that are being contested in good faith. The reserves for accrued Taxes reflected in the financial

statements delivered to the Lenders under this Agreement are adequate in the aggregate for the payment of all unpaid Taxes, whether or not disputed, for the period ended as of the date thereof and for any period prior thereto, and for which the Tax Group may be liable in its own right, as withholding agent or as a transferee of the assets of, or successor to, any Person.

(b) Taxes Definition. “Taxes” in this Section 4.11 shall mean all taxes, charges, fees, levies, or other assessments imposed by any federal, state, local, or foreign taxing authority, including without limitation, income, gross receipts, excise, real or personal property, sales, occupation, use, service, leasing, environmental, value added, transfer, payroll, and franchise taxes (and including any interest, penalties, or additions to tax attributable to or imposed on with respect to any such assessment).

(c) Returns Definition. “Returns” in this Section 4.11 shall mean any federal, state, local, or foreign report, estimate, declaration of estimated Tax, information statement or return relating to, or required to be filed in connection with, any Taxes, including any information return or report with respect to backup withholding or other payments of third parties.

Section 4.12 Pension Plans. All Plans are in compliance in all material respects with all applicable provisions of ERISA. No Termination Event has occurred with respect to any Plan, and each Plan has complied with and been administered in all material respects in accordance with applicable provisions of ERISA and the Code. No “accumulated funding deficiency” (as defined in Section 302 of ERISA) has occurred with respect to any Plan and there has been no excise tax imposed under Section 4971 of the Code with respect to any Plan. No Reportable Event has occurred, whether individually or in the aggregate, with respect to any Multiemployer Plan, and each Multiemployer Plan has complied with and been administered in all material respects with in accordance with applicable provisions of ERISA and the Code. The present value of all benefits vested under each Plan (based on the assumptions used to fund such Plan) did not, as of the last annual valuation date applicable thereto, exceed the value of the assets of such Plan allocable to such vested benefits by an amount that could reasonably be expected to give rise to a Material Adverse Change. No Borrower and no member of the Controlled Group has had a complete or partial withdrawal from any Multiemployer Plan for which any Borrower has any withdrawal liability. As of the most recent valuation date applicable thereto, no Borrower nor any of their respective ERISA Affiliates would become subject to any liability under ERISA if a Borrower or any of ERISA Affiliate of a Borrower has received notice that any Multiemployer Plan is insolvent or in reorganization. Based upon GAAP existing as of the date of this Agreement and current factual circumstances, no Borrower has reason to believe that the annual cost during the term of this Agreement to the Borrowers or any ERISA Affiliate of a Borrower for post-retirement benefits to be provided to the current and former employees of a Borrower or any ERISA Affiliate of a Borrower under Plans that are welfare benefit plans (as defined in Section 3(1) of ERISA) could, in the aggregate, reasonably be expected to cause a Material Adverse Change.

Section 4.13 Condition of Property; Casualties. Each Borrower and each of their respective Subsidiaries has good and defensible title to all of its Properties as is customary in the oil and gas industry in all material respects, free and clear of all Liens except for Permitted Liens. The material Properties used or to be in the continuing operations of the Borrowers and their respective Subsidiaries are in reasonably good repair, working order and condition

(ordinary wear and tear excepted). Except for any adverse change directly resulting from the effects of Hurricane Gustav or Hurricane Ike, since the Closing Date, neither the business nor any Property of the Borrowers and their respective Subsidiaries has been affected as a result of any fire, explosion, earthquake, flood, drought, windstorm, accident, strike or other labor disturbance, embargo, requisition or taking of Property or cancellation of contracts, Permits, or concessions by a Governmental Authority, riot, activities of armed forces, or acts of God or of any public enemy (whether or not covered by insurance).

Neither the Administrative Agent nor any of its Related Parties shall be liable for any action taken or omitted to be taken (INCLUDING THE ADMINISTRATIVE AGENT’S OR SUCH RELATED PARTY’S OWN NEGLIGENCE) by it or them under or in connection with this Agreement or the other Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Administrative Agent: (a) may treat the payee of any Note as the holder thereof until the Administrative Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to the Administrative Agent; (b) may consult with legal counsel (including counsel for the Borrowers), independent public accountants, and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants, or experts; (c) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties, or representations made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or any other Loan Document on the part of any Borrower or any Subsidiary of a Borrower or to inspect the Property (including the books and records) of any Borrower or any Subsidiary of a Borrower; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency, or value of this Agreement

Section 9.03 The Administrative Agent and Its Affiliates. With respect to its Commitment, the Advances made by it and the Notes issued to it, the Administrative Agent shall have the same rights and powers under this Agreement as any other Lender and may exercise the same as though it were not the Administrative Agent. The term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include the Administrative Agent in its individual capacity. The Administrative Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with, any Borrower or any Subsidiary of a Borrower, and any Person who may do business with or own securities of any Borrower or any such Subsidiary, all as if the Administrative Agent were not an agent hereunder and without any duty to account therefor to the Lenders.

Section 9.04 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on the Combined Initial Financial Statements and the Combined Interim Financial Statements and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it shall, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement.

Section 9.05 Indemnification.

WITHOUT LIMITATION OF THE FOREGOING, EACH LENDER AGREES TO REIMBURSE THE ADMINISTRATIVE AGENT AND THE ISSUING LENDER PROMPTLY UPON DEMAND FOR ITS RATABLE

SHARE OF ANY OUT OF POCKET EXPENSES (INCLUDING COUNSEL FEES) INCURRED BY THE ADMINISTRATIVE AGENT IN CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY, ADMINISTRATION, MODIFICATION, AMENDMENT, OR ENFORCEMENT (WHETHER THROUGH NEGOTIATIONS, LEGAL PROCEEDINGS, OR OTHERWISE) OF, OR LEGAL ADVICE IN RESPECT OF RIGHTS OR RESPONSIBILITIES UNDER, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, TO THE EXTENT THAT THE ADMINISTRATIVE AGENT OR THE ISSUING LENDER IS NOT REIMBURSED FOR SUCH BY A BORROWER.

Section 9.06 Successor Administrative Agent and Issuing Lender. The Administrative Agent or the Issuing Lender may resign at any time by giving written notice thereof to the Lenders and the Borrower Representative and may be removed at any time with or without cause by the Required Lenders upon receipt of written notice from the Required Lenders to such effect. Upon receipt of notice of any such resignation or removal, the Required Lenders shall have the right to appoint a successor Administrative Agent or Issuing Lender with, if any Event of Default has not occurred and is not continuing, the consent of the Borrower Representative, which consent shall not be unreasonably withheld. If no successor Administrative Agent or Issuing Lender shall have been so appointed by the Required Lenders with the consent of the Borrower Representative, and shall have accepted such appointment, within 30 days after the retiring Administrative Agent’s or Issuing Lender’s giving of notice of resignation or the Required Lenders’ removal of the retiring Administrative Agent or Issuing Lender, then the retiring Administrative Agent or Issuing Lender may, on behalf of the Lenders and the Borrowers, appoint a successor Administrative Agent or Issuing Lender, which shall be, in the case of a successor agent, a commercial bank organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000.00 and, in the case of the Issuing Lender, a Lender. Upon the acceptance of any appointment as Administrative Agent or Issuing Lender by a successor Administrative Agent or Issuing Lender, such successor Administrative Agent or Issuing Lender shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Administrative Agent or Issuing Lender, and the retiring Administrative Agent or Issuing Lender shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that the retiring Issuing Lender shall remain the Issuing Lender with respect to any Letters of Credit outstanding on the effective date of its resignation or removal and the provisions affecting the Issuing Lender with respect to such Letters of Credit shall inure to the benefit of the retiring Issuing Lender until the termination of all such Letters of Credit. After any retiring Administrative Agent’s or Issuing Lender’s resignation or removal hereunder as Administrative Agent or Issuing Lender, the provisions of this Article IX shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Issuing Lender under this Agreement and the other Loan Documents.

The Administrative Agent is further authorized (but not

obligated) on behalf of the Secured Parties, without the necessity of any notice to or further consent from the Secured Parties, from time to time, to take any action in exigent circumstances as may be reasonably necessary to preserve any rights or privileges of the Secured Parties under the Loan Documents or applicable Legal Requirement.

By executing and delivering an Assignment and Assumption, the Lender thereunder and the assignee thereunder confirm to and agree with each other and the other parties hereto as follows: (i) other than as provided in such Assignment and Assumption, such Lender makes no representation or warranty and assumes no responsibility with respect to any statements, warranties or representations made in or in connection with this Agreement or the execution, legality, validity, enforceability, genuineness, sufficiency of value of this Agreement or any other instrument or document furnished pursuant hereto; (ii) such Lender makes no representation or warranty and assumes no responsibility with respect to the financial condition of any Borrower or any Subsidiary of a Borrower or the performance or observance by any Borrower or any Subsidiary of a Borrower of any of their respective obligations under this Agreement or any other instrument or document furnished pursuant hereto; (iii) such assignee confirms that it has received a copy of this Agreement, together with copies of the Combined Initial Financial Statements and Combined Interim Financial Statements referred to in Section 4.05 and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into such Assignment and Assumption; (iv) such assignee will, independently and without reliance upon the Administrative Agent, such Lender or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement; (v) such assignee appoints and authorizes the Administrative Agent to take such action as agent on its behalf and to exercise such powers under this Agreement as are delegated to the Administrative Agent by the terms hereof, together with such powers as are reasonably incidental thereto; and (vi) such assignee agrees that it will perform in accordance with their terms all of the obligations which by the terms of this Agreement are required to be performed by it as a Lender.

The Administrative Agent shall maintain at its address referred to in Section 10.02 a copy of each Assignment and Assumption 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 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 Borrowers, the Administrative Agent, the Issuing Lender, 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 Borrowers or any Lender at any reasonable time and from time to time upon reasonable prior notice.

(iv) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement (including under its Note(s)) to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Art. ▇▇▇▇, ▇▇. 15)), shall not apply to this Agreement, the Notes, or the transactions contemplated hereby and (b) to the extent that any Lender may be subject to Texas law limiting the amount of interest payable for its account, such Lender shall utilize the indicated (weekly) rate ceiling from time to time in effect.

Each Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Section 10.14 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 any Borrower or any Property of any Borrower in the courts of any other jurisdiction.

Section 10.15 Confidentiality. Each of the Administrative Agent and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable Legal Requirement or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 10.15, to (i) any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to a Borrower and its obligations, (g) with the consent of the Borrower Representative or (h) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section 10.15 or (y) becomes available to the Administrative Agent or any Lender on a nonconfidential basis from a source other than a Borrower. For purposes of this Section 10.15, “Information” means all information received from a Borrower or any of Subsidiary of a
