This SEVENTH AMENDMENT TO THIRD AMENDED AND RESTATED CREDIT AGREEMENT (this “ Amendment ”) is entered into as of October 16, 2015, by and among MRC ENERGY COMPANY, a Texas corporation (the “ Borrower ”), the LENDERS party hereto and ROYAL BANK OF CANADA, as Administrative Agent for the Lenders (in such capacity, the “ Administrative Agent ”). Unless otherwise expressly defined herein, capitalized terms used but not defined in this Amendment have the meanings assigned to such terms in the Credit Agreement (as defined below).

WITNESSETH:

WHEREAS, the Borrower, the Administrative Agent and the Lenders have entered into that certain Third Amended and Restated Credit Agreement, dated as of September 28, 2012 (as the same has been and may hereafter be amended, restated, supplemented or otherwise modified from time to time, the “ Credit Agreement ”); and

WHEREAS, the Borrower has requested that the Administrative Agent and the Lenders amend the Credit Agreement in certain respects and the Administrative Agent and the Lenders have agreed to do so on the terms and conditions hereinafter set forth.

NOW, THEREFORE, for and in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and confessed, the Borrower, the Administrative Agent and the Lenders hereby agree as follows:

SECTION 1. Amendments to Credit Agreement. Subject to the satisfaction or waiver in writing of each condition precedent set forth in Section 3 of this Amendment, and in reliance on the representations, warranties, covenants and agreements contained in this Amendment, the Credit Agreement shall be amended in the manner provided in this Section 1 .

1.1      Amended Definitions . The following definition in Section 1.1 of the Credit Agreement shall be and it hereby is amended and restated in its entirety to read as follows:

“ Revolving Credit Maturity Date ” means October 16, 2020.

1.2      Additional Definitions. The following definition shall be and it hereby is added to Section 1.1 of the Credit Agreement in alphabetical order:

“ Seventh Amendment Effective Date ” means October 16, 2015.

1.3      Borrowing Base . Section 4.1 of the Credit Agreement shall be and it hereby is amended and restated in its entirety to read as follows:

4.1     Borrowing Base . The term “ Conforming Borrowing Base ” means, as of the date of determination thereof prior to the Borrowing Base Equalization

Date, the designated loan value as calculated by Lenders in their sole discretion assigned to the discounted present value of future net income accruing to the Borrowing Base Properties, based upon Lenders’ in-house evaluation of Borrowing Base Properties. Before the Borrowing Base Equalization Date the term “ Borrowing Base ” has the meaning set forth below, and will be determined in relation to the Conforming Borrowing Base. On and after the Borrowing Base Equalization Date, the term “ Borrowing Base ” means, as of the date of determination thereof, the designated loan value as calculated by Lenders in their sole discretion assigned to the discounted present value of future net income accruing to the Borrowing Base Properties, based upon Lenders’ in-house evaluation of Borrowing Base Properties. The Lenders’ determination of the Conforming Borrowing Base and Borrowing Base will be made in accordance with then-current practices, economic and pricing parameters, methodology, assumptions, and customary procedures and standards established by each Lender from time to time for its petroleum industry customers including without limitation (a) an analysis of such reserves and production data with respect to the Hydrocarbon Interests of the Credit Parties in all of their Oil and Gas Properties, including the Mortgaged Properties, as is provided to Lenders in accordance herewith, (b) an analysis of the assets, liabilities, cash flow, business, properties, prospects, management and ownership of each Credit Party, and (c) such other credit factors as each Lender customarily considers in evaluating similar oil and gas credits. Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (collateral value in excess of loan amount) which Borrower acknowledges to be essential for the adequate protection of Lenders. As of the Seventh Amendment Effective Date, the Borrowing Base and the Conforming Borrowing Base shall be $375,000,000. Prior to the Borrowing Base Equalization Date, any increase in the Conforming Borrowing Base as a result of the most recent redetermination thereof shall result in an equal increase in the Borrowing Base. On and after the Borrowing Base Equalization Date, the Borrowing Base shall equal the Conforming Borrowing Base then in effect and all references to Conforming Borrowing Base and Borrowing Base shall mean the Borrowing Base then in effect.

SECTION 2.      Redetermined Borrowing Base. This Amendment shall constitute notice of a redetermination of the Borrowing Base pursuant to Section 4.2 of the Credit Agreement, and the Administrative Agent, the Lenders and the Borrower hereby acknowledge that effective as of the date hereof the Borrowing Base shall be $375,000,000 and such redetermined Borrowing Base shall remain in effect until the date the Borrowing Base is otherwise adjusted pursuant to the terms of the Credit Agreement. The redetermination of the Borrowing Base contained in this Section 2 shall constitute the Determination Date to occur on or about November 1, 2015.

SECTION 3.      Conditions . The amendments to the Credit Agreement contained in Section 1 of this Amendment and the redetermination of the Borrowing Base contained in Section 2 of this Amendment shall be effective upon the satisfaction of each of the conditions set forth in this Section 3 .

3.1      Execution and Delivery. The Administrative Agent shall have received a duly executed counterpart of (a) this Amendment signed by the Borrower and the Lenders and (b) the Consent and Reaffirmation attached hereto signed by each Guarantor, in each case, in form and substance reasonably satisfactory to the Administrative Agent.

SECTION 4.      Representations and Warranties. To induce the Lenders to enter into this Amendment, the Borrower hereby represents and warrants to the Lenders as follows:

4.1      Reaffirmation of Representations and Warranties. After giving effect to the amendments herein, each representation and warranty of the Borrower, the Parent and each other Credit Party contained in the Credit Agreement and in each of the other Loan Documents to which it is a party is true and correct in all material respects as of the date hereof (without duplication of any materiality qualifier contained therein), except to the extent any such representations and warranties are expressly limited to an earlier date, in which case, such representations and warranties shall continue to be true and correct in all material respects (without duplication of any materiality qualifier contained therein) as of such specified earlier date.

4.3      Enforceability. This Amendment constitutes the valid and binding obligation of the Borrower enforceable in accordance with its terms, except as (i) the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditor’s rights generally, and (ii) the availability of equitable remedies may be limited by equitable principles of general application.
