(d) Section 2.01 of the Credit Agreement is hereby amended to add the following as new subsection (b):

(e) The heading to Section 2.02 and Section 2.02(a) of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

(a) Each Borrowing, each conversion of Revolving Loans from one Type to the other, and each continuation of Eurodollar Rate Loans shall be made upon Borrower’s irrevocable notice to Agent, which may be given by telephone, provided that such notice is promptly followed by facsimile notice. Each such notice, and each Term Loan Notice, must be received by Agent not later than 11:00 a.m., Central Time, (i) three Business Days prior to the requested date of any Borrowing of, conversion to or continuation of Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans. Each telephonic notice by Borrower pursuant to this Section 2.02(a) with respect to Loans must be confirmed promptly by delivery to Agent of a written Revolving Loan Notice or Term Loan Notice, as applicable, appropriately completed and signed by a Responsible Officer of Borrower. With respect to Revolving Loans, each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall be in a principal amount of $500,000 or a greater integral multiple of $100,000. Each Borrowing of or conversion to Base Rate Loans shall be in a principal amount of $100,000 or a greater integral multiple of $100,000. Each Revolving Loan Notice (whether telephonic or written) shall specify (i) whether Borrower is requesting a Borrowing, a conversion of Revolving Loans from one Type to the other, or a continuation of Revolving Loans that are Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion or continuation, as the case may be (which shall be a Business Day), (iii) the principal amount of Revolving Loans to be borrowed, converted or continued, (iv) the Type of Revolving Loans to be borrowed or to which existing Revolving Loans are to be converted, and (v) if applicable, the duration of the Interest Period with respect thereto. With respect to Revolving Loans, if Borrower fails to specify a Type of Revolving Loan in a Revolving Loan Notice or if

Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Revolving Loans shall be made, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable Eurodollar Rate Loans. If Borrower requests a Borrowing of, conversion to, or continuation of Revolving Loans that are Eurodollar Rate Loans in any such Revolving Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month. The Term Loan shall initially be made (without the Borrower being required to submit a Term Loan Notice) as a Eurodollar Rate Loan having an Interest Period of one month. The Term Loan shall be automatically continued (without the Borrower being required to submit a Term Loan Notice) as a Eurodollar Rate Loan having an Interest Period of one month on the last day of the immediately preceding Interest Period, unless otherwise specified in a Term Loan Notice delivered to the Agent. Each Term Loan Notice (whether telephonic or written) shall specify (i) whether Borrower is requesting a conversion of the Term Loan from one Type to the other, or a continuation of the Term Loan as a Eurodollar Rate Loan, (ii) the requested date of the conversion or continuation, as the case may be (which shall be a Business Day), and (iii) if applicable, the duration of the Interest Period with respect thereto.

(f) Section 2.02(e) of the Credit Agreement is hereby amended to add the following sentence to the end of such subsection:

(g) Section 2.05 of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

(a) Optional. Borrower may, upon notice to Agent, at any time or from time to time voluntarily prepay Loans in whole or in part without premium or penalty; provided that (i) such notice must be received by Agent not later than 11:00 a.m., Central Time, (A) five Business Days prior to any date of prepayment of Eurodollar Rate Loans, and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of $500,000 or a greater integral multiple of $100,000; and (iii) any prepayment of Base Rate Loans shall be in a principal amount of $100,000 or a greater integral multiple of $100,000, or, in each case, if less, the entire principal amount thereof then outstanding. Each such notice shall specify the date and amount of such prepayment, whether such prepayment is of the Term Loan or Revolving Loans, and the Type(s) of Loans to be prepaid. Agent will promptly notify each Lender of its receipt

of each such notice, and of the amount of such Lender’s Pro Rata Share of such prepayment or such Lender’s Term Pro Rata Share of such prepayment, as applicable. If such notice is given by Borrower, Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all accrued interest thereon, together with any additional amounts required pursuant to Section 3.05. Each Revolving Loan prepayment shall be applied to the Revolving Loans of Lenders in accordance with their respective Pro Rata Shares and each Term Loan prepayment shall be applied to the Term Loan of Lenders in accordance with their respective Term Pro Rata Shares.

(i) Overadvance. If for any reason (including a redetermination of the Borrowing Base) the Total Outstandings at any time exceed the lesser of Aggregate Commitments then in effect and the Borrowing Base then in effect (after giving effect to Section 2.05(b)(vi), Borrower shall immediately (and in any event within three (3) Business Days) (1) prepay Revolving Loans and/or Cash Collateralize the L/C Obligations in an aggregate amount equal to such excess or (2) add to the Borrowing Base Oil and Gas Properties additional Oil and Gas Properties of the Borrower sufficient in value, as determined pursuant to Section 2.04, to increase the Borrowing Base to equal or exceed the Total Outstandings.

(ii) Dispositions. Upon the occurrence of any Disposition (including any Disposition of any Borrowing Base Oil and Gas Properties) or any Recovery Event (except (A) Dispositions pursuant to Section 7.05(a), (c) or (d) and (B) with respect to Net Cash Proceeds received with respect to (i) Dispositions in an aggregate amount not to exceed $1,500,000 during any fiscal year or (ii) a Recovery Event, in each case in which such Net Cash Proceeds are utilized in order to replace or repair the assets of the Borrower or any Subsidiary that are the subject of such Disposition or Recovery Event (or, in the case of a Recovery Event, are utilized by the Borrower or the applicable Subsidiary to reimburse itself for expenditures previously made in order to replace or repair such assets in an aggregate amount not to exceed $4,000,000 during any fiscal year)), then on the date of receipt by the Borrower or the applicable Subsidiary of the Net Cash Proceeds related thereto, the Loans shall immediately be prepaid in accordance with Section 2.05(b)(viii) by an amount equal to the amount of such Net Cash Proceeds minus the amount of any mandatory prepayment made pursuant to Section 2.05(b)(i)

in connection with such Disposition or Recovery Event. Notwithstanding the foregoing, the Borrower may retain Net Cash Proceeds in an amount not to exceed $100,000 in the aggregate for Dispositions made by the Borrower or its Subsidiaries during any fiscal year. For purposes of calculating the Net Cash Proceeds received from a Disposition or from a Recovery Event, such proceeds shall be determined as of the date of the applicable Disposition or Recovery Event, whether or not received on such date, but no such amount shall be required to be applied to prepayment of the Loans pursuant to this Section until received by the applicable Person. The provisions of this Section do not constitute consent to the consummation of any Disposition not otherwise permitted by Section 7.05.

(iii) Indebtedness Issuance. If any Indebtedness for borrowed money shall be issued or incurred by the Borrower or any of its Subsidiaries (excluding any Indebtedness incurred in accordance with Section 7.03(a), (b), (c), (d), (e), (f), and (g)), then on the date of such issuance or incurrence, the Loans shall be prepaid by an amount equal to the amount of the Net Cash Proceeds of such issuance or incurrence, in accordance with Section 2.05(b)(viii). The provisions of this Section do not constitute consent to the issuance or incurrence of any Indebtedness by the Borrower or any of its Subsidiaries not otherwise permitted hereunder.

(iv) Equity Issuance. If the Borrower or any Subsidiary consummates an Equity Issuance, then Equity Issuance Proceeds received by the Borrower or any of its Subsidiaries shall be immediately applied to prepay the Loans on the date such Equity Issuance Proceeds are received in accordance with Section 2.05(b)(viii); provided, however, the Borrower shall not nor shall it permit any Subsidiary to issue any equity interests (other than to the Borrower or any of its Subsidiaries in the ordinary course of business in an aggregate amount not to exceed $500,000 during any fiscal year) if a Default shall be existing immediately after giving effect thereto or would result therefrom.

(v) Termination of Swap Contracts. If the Borrower or any Subsidiary shall settle, unwind or otherwise terminate any Swap Contract (not including the ordinary course settlement of Forward Sales Contracts, but including any early monetization or termination of such Forward Sales Contracts), then on the date of receipt by the Borrower or any such Subsidiary of the Net Cash Proceeds related thereto, the Loans shall be immediately prepaid by an amount equal to the amount of such Net Cash Proceeds in accordance with Section 2.05(b)(viii).

(vi) Disposition of Borrowing Base Oil and Gas Properties. On each date on which Borrower sells any of its Borrowing Base Oil and Gas Properties, the Borrowing Base shall be automatically reduced to the loan value (determined in accordance with the procedures for determining the Borrowing Base) of the remaining Borrowing Base Oil and Gas Properties, and the Borrower shall be required to make a prepayment, if any, required to Section 2.05(b)(i).

(vii) Accrued Interest. Each prepayment under 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 Article III as a result of such prepayment.

(viii) Application of Prepayments. Prepayments required under this Section 2.05(b) shall be applied, first, to the Term Loan in inverse order of maturity, second to the Revolving Loan, with no reduction of the Aggregate Commitments as a result thereof, and third, to the extent that there are no Revolving Loans outstanding, to Cash Collateralize the L/C Obligations in accordance with Section 2.03.

(h) Section 2.06 of the Credit Agreement is hereby amended to add “(a)” after the heading thereof and to add a new subsection (b) to read as follows:

(b) Borrower shall repay the principal amount of the Term Loan to Lenders in monthly installments of $1,000,000 each, due and payable on the last Business Day of each calendar month, commencing on September 30, 2009. Borrower shall repay to Lenders on the Maturity Date the aggregate principal amount of the Term Loan outstanding on such date, together with all accrued and unpaid interest and fees.

(i) Section 2.11(a) of the Credit Agreement is hereby amended and restated in its entirety to read as follows:

Lending Office. All payments received by Agent after 12:00 noon, Central Time, shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue.

(ii) On each date when the payment of any principal, interest or fees are due hereunder or under any Note, Borrower agrees to maintain on deposit in an ordinary checking account maintained by Borrower with Agent (as such account shall be designated by Borrower in a written notice to Agent from time to time, the “Borrower Account”) an amount sufficient to pay such principal, interest or fees in full on such date. Borrower hereby authorizes Agent, upon notice to Borrower (which notice may be by telephone) (A) to deduct automatically all principal, interest or fees when due hereunder or under any Note from Borrower Account, and (B) if and to the extent any payment of principal, interest or fees under this Agreement or any Note is not made when due to automatically deduct any such amount from any or all of the accounts of Borrower maintained at Agent. Agent agrees to provide written notice to Borrower of any automatic deduction made pursuant to this Section 2.11(a)(ii) showing in reasonable detail the amounts of such deduction.

(a) Releasor hereby releases and forever discharges Agent and each Lender and Agent’s and each Lender’s predecessors, successors, assigns, officers, managers, directors, shareholders, employees, agents, attorneys, representatives, parent corporations, subsidiaries, and affiliates (hereinafter all of the above collectively referred to as “Lender Group”) jointly and severally from any and all claims, counterclaims, demands, damages, debts, agreements, covenants, suits, contracts, obligations, liabilities, accounts, offsets, rights, actions, and causes of action of any nature whatsoever occurring prior to the date hereof, including, without limitation, all claims, demands, and causes of action for contribution and indemnity, whether arising at law or in equity, presently possessed, whether known or unknown, whether liability be direct or indirect, liquidated or unliquidated, presently accrued, whether absolute or contingent, foreseen or unforeseen, and whether or not heretofore asserted (“Claims”), which Releasor may have or claim to have against any of Lender Group; except, as to any member of the Lender Group, to the extent that any such Claim results from any gross negligence or willful misconduct of that member.

(b) Releasor agrees not to sue any of Lender Group or in any way assist any other Person in suing Lender Group with respect to any Claim released herein. The Release Provision may be pleaded as a full and complete defense to, and may be used as the basis for an injunction against, any action, suit, or other proceeding which may be instituted, prosecuted, or attempted in breach of the release contained herein.

(i) Releasor has read and understands the effect of the Release Provision. Releasor has had the assistance of independent counsel of its own choice, or has had the opportunity to retain such independent counsel, in reviewing, discussing, and considering all the terms of the Release Provision; and if counsel was retained, counsel for Releasor has read and considered the Release Provision and advised Releasor to execute the same. Before execution of this Amendment, Releasor has had adequate opportunity to make whatever investigation or inquiry it may deem necessary or desirable in connection with the subject matter of the Release Provision.

(ii) Releasor is not acting in reliance on any representation, understanding, or agreement not expressly set forth herein. Releasor acknowledges that Lender Group has not made any representation with respect to the Release Provision except as expressly set forth herein.

(iii) Releasor has executed this Amendment and the Release Provision thereof as its free and voluntary act, without any duress, coercion, or undue influence exerted by or on behalf of any person.

(iv) Releasor is the sole owner of the claims released by the Release Provision, and Releasor has not heretofore conveyed or assigned any interest in any such claims to any other person or entity.

(d) Releasor understands that the Release Provision was a material consideration in the agreement of the Agent and each Lender to enter into this Amendment.

(e) It is the express intent of Releasor that the release and discharge set forth in the Release Provision be construed as broadly as possible in favor of Lender Group so as to foreclose forever the assertion by Releasor of any Claims released hereby against Lender Group.

(f) If any term, provision, covenant, or condition of the Release Provision is held by a court of competent jurisdiction to be invalid, illegal, or unenforceable, the remainder of the provisions shall remain in full force and effect.

(a) No Waiver of Defaults. This Amendment does not constitute (i) a waiver of, or a consent to, (A) any provision of the Credit Agreement or any other Loan Document not expressly referred to in this Amendment, or (B) any present or future violation of, or default under, any provision of the Loan Documents, or (ii) a waiver of Lenders’ and Agent’s right to insist upon future compliance with each term, covenant, condition and provision of the Loan Documents, as amended and waived by this Amendment.

(b) Form. Each agreement, document, instrument or other writing to be furnished Lenders and Agent under any provision of this Amendment must be in form and substance reasonably satisfactory to Lenders, Agent and their counsel.

(c) Headings. The headings and captions used in this Amendment are for convenience only and will not be deemed to limit, amplify or modify the terms of this Amendment, the Credit Agreement, or the other Loan Documents.

(d) Costs, Expenses and Attorneys’ Fees. Borrower agrees to pay or reimburse Lenders and Agent on demand for all its reasonable out-of-pocket costs and expenses incurred in connection with the preparation, negotiation, and execution of this Amendment, including, without limitation, the reasonable fees and disbursements of Lenders’ and Agent’s counsel.

(e) Successors and Assigns. This Amendment shall be binding upon and inure to the benefit of each of the undersigned and their respective successors and permitted assigns.

(f) Multiple Counterparts. This Amendment may be executed in any number of counterparts with the same effect as if all signatories had signed the same document. All counterparts must be construed together to constitute one and the same instrument. This Amendment may be transmitted and signed by facsimile or by portable document format (PDF). The effectiveness of any such documents and signatures shall, subject to applicable law, have the same force and effect as manually-signed originals and shall be binding on Borrower, Lenders and Agent. Lenders and Agent may also require that any such documents and signatures be confirmed by a manually-signed original; provided that the failure to request or deliver the same shall not limit the effectiveness of any facsimile or PDF document or signature.

(g) Governing Law. This Amendment and the other Loan Documents must be construed, and their performance enforced, under Texas law.

(h) Entirety. THE LOAN DOCUMENTS (AS AMENDED AND WAIVED HEREBY) REPRESENT THE FINAL AGREEMENT BY AND BETWEEN BORROWER, LENDERS AND AGENT AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

This Amendment is executed as of the date set out in the preamble to this Amendment.
