NOW, THEREFORE, in consideration of these premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1.    Same Terms. All terms used herein that are defined in the Original Credit Agreement shall have the same meanings when used herein, unless the context hereof otherwise requires or provides. In addition, from and after the Effective Date, (i) all references in the Original Credit Agreement and, where appropriate in the context, in the other Loan Documents to the “Agreement” shall mean the Original Credit Agreement, as amended and waived by this Amendment, as the same may hereafter be amended and waived from time to time, and (ii) all references in the Loan Documents to the “Loan Documents” shall mean the Loan Documents, as amended and waived by the Modification Papers, as the same may hereafter be amended and waived from time to time.

3.    Amendments to Original Credit Agreement. On the Effective Date, the Original Credit Agreement shall be deemed to be amended as follows:

(a)    The definition of EBITDAX contained in Section 1.01 of the Original Credit Agreement shall be amended to read in its entirety as follows:

“‘EBITDAX’ means net income, excluding (i) any non-cash revenue or expense associated with Swap Contracts resulting from ASC 815 and (ii) any cash or non-cash revenue or expense attributable to minority investments, plus without duplication and, in the case of expenses, to the extent deducted from revenues in determining net income, the sum of (a) the aggregate amount of consolidated Interest Expense for such period, (b) the aggregate amount of income, franchise, capital or similar tax expense (other than ad valorem taxes) for such period, (c) all amounts attributable to depletion, depreciation, amortization and asset or goodwill impairment or writedown for such period, (d) all other non-cash charges, (e) exploration costs deducted in determining net income under successful efforts accounting, (f) actual cash distributions received from minority investments (but, for the avoidance of doubt, not including proceeds received from Dispositions of such minority investments), (g) to the extent actually reimbursed by insurance, expenses with respect to liability on casualty events or business interruption, and (h) all reasonable transaction expenses related to Dispositions and acquisitions of assets, investments and debt and equity offerings by any Loan Party (in each case whether or not successful, provided that expenses related to unsuccessful Dispositions shall be limited to $3,000,000 in the aggregate for the period from the Closing Date to the Maturity Date), all determined on a consolidated basis with respect to Borrower and its Subsidiaries in accordance with GAAP, using the results of the twelve-month period ending with that reporting period. For the purposes of calculating EBITDAX for any test period of four consecutive fiscal quarters (each, a “Reference Period”), (i) if during such Reference Period Borrower or any Subsidiary shall have made a Material Disposition or Material Acquisition, EBITDAX for such Reference Period shall be calculated on a pro forma basis as if such Material Disposition or Material Acquisition had occurred on the first day of such Reference Period, and (ii) solely with respect to calculations made in connection with determining pro forma compliance with covenants set forth in the Loan Documents, EBITDAX for a Reference Period shall be calculated on a pro forma basis as if Material Dispositions and Material Acquisitions made during or after the end of the Reference Period but on or before the date of determination had occurred on the first day of such Reference Period.”

(b)    The following definitions shall be added in appropriate alphabetical order to Section 1.01 of the Original Credit Agreement to read in their respective entireties as follows:

“‘Material Acquisition’ means any acquisition of property or series of related acquisitions of properties (including by way of merger or consolidation) that involves the payment of consideration by Borrower and its Subsidiaries in excess of $50,000,000.

EIGHTH AMENDMENT – Page 2

‘Material Disposition’ means any Disposition of property or series of related Dispositions of properties that yields gross proceeds to Borrower or any of its Subsidiaries in excess of $50,000,000.”

4.    Certain Representations. Borrower represents and warrants that, as of the Effective Date: (a) Borrower has full power and authority to execute the Modification Papers to which it is a party and such Modification Papers constitute the legal, valid and binding obligation of Borrower enforceable in accordance with their terms, except as enforceability may be limited by general principles of equity and applicable bankruptcy, insolvency, reorganization, moratorium, and other similar laws affecting the enforcement of creditors’ rights generally; (b) no authorization, approval, consent or other action by, notice to, or filing with, any Governmental Authority or other Person is required for the execution, delivery and performance by Borrower thereof; and (c) no Default has occurred and is continuing or will result from the consummation of the transactions contemplated by this Amendment. In addition, Borrower represents that after giving effect to the Modification Papers, all representations and warranties contained in the Credit Agreement and the other Loan Documents are true and correct in all material respects (provided that any such representations or warranties that are, by their terms, already qualified by reference to materiality shall be true and correct without regard to such additional materiality qualification) on and as of the Effective Date as if made on and as of such date except to the extent that any such representation or warranty expressly relates to an earlier date, in which case such representation or warranty is true and correct in all material respects (or true and correct without regard to such additional materiality qualification, as applicable) as of such earlier date.

5.    No Further Amendments. Except as previously amended or waived in writing or as amended or waived hereby, the Original Credit Agreement shall remain unchanged and all provisions shall remain fully effective between the parties thereto.

7.    Limitation on Agreements. The consents, waivers and modifications set forth herein are limited precisely as written and shall not be deemed (a) to be a consent under or a waiver of or an amendment to any other term or condition in the Original Credit Agreement or any of the other Loan Documents, or (b) to prejudice any other right or rights that Administrative Agent or the Lenders now have or may have in the future under or in connection with the Original Credit Agreement and the other Loan Documents, each as amended and waived hereby, or any of the other documents referred to herein or therein. The Modification Papers shall constitute Loan Documents for all purposes.

8.    Confirmation of Security. Borrower hereby confirms and agrees that all of the Collateral Documents that presently secure the Obligations shall continue to secure, in the same manner and to the same extent provided therein, the payment and performance of the Obligations as described in the Original Credit Agreement as modified by this Amendment.

9.    Counterparts. This Amendment may be executed in any number of counterparts, each of which when executed and delivered shall be deemed an original, but all of which constitute one instrument.
