SECTION 2.  Amendment to Credit Agreement.  Section 1.1 of the Credit Agreement is hereby amended by replacing the definitions of “Authorized Officer”, “Capital” and “Consolidated Tangible Net Worth” with the following:

“ “Authorized Officer” means, with respect to any Borrower, the chief executive officer and/or president, the chief financial officer, and the treasurer of such Borrower, and any officer or employee of such Borrower specified as such to the Administrative Agent in writing by any of the aforementioned officers of such Borrower.”

“ “Capital” means the consolidated shareholder’s equity of Apache and its Subsidiaries plus the consolidated Debt of Apache and its Subsidiaries, provided that such calculation shall exclude the effects of non-cash write-downs, impairments, and related charges occurring after June 30, 2015, including, without limitation, those which may be required under Rule 4-10 (Financial Accounting and Reporting for Oil and Gas Producing Activities Pursuant to the Federal Securities Laws and the Energy Policy and Conservation Act of 1975) of Regulation S-X promulgated by the SEC or by GAAP.”

SECTION 3. Effectiveness. This Amendment shall become effective on the date when the Administrative Agent shall have received counterparts hereof duly executed by Borrower, the Administrative Agent, and the Required Lenders.

SECTION 4. Reaffirmation of Representations and Warranties. To induce the Lenders and the Administrative Agent to enter into this Amendment, Borrower hereby reaffirms, as of the date hereof, the following:

(i) The representations and warranties of Borrower set forth in the Credit Agreement are true and correct on and as of the date hereof (unless stated to relate solely to an earlier date, in which case such representations and warranties shall be true and correct as of such earlier date).

(ii) The Borrower is duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all requisite authority, permits and approvals, and is in good standing to conduct its business in each jurisdiction in which its business is conducted where the failure to so qualify would have a Material Adverse Effect.

(iii) The execution, delivery and performance by Borrower of this Amendment are within Borrower’s corporate powers and have been duly authorized by all necessary corporate action on behalf of it.

(iv) This Amendment has been duly executed and delivered by Borrower and constitutes a legal, valid and binding obligation of Borrower enforceable in accordance with its terms subject as to enforcement only to bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditor rights generally and to general principles of equity.

(v) The execution, delivery and performance by Borrower of this Amendment do not (a) contravene Borrower’s articles of incorporation or other organizational documents or (b) contravene any material contractual restriction, law or governmental regulation or court decree or order binding on or affecting Borrower or any Subsidiary.

(vi) No Default under the Loan Documents has occurred and is continuing and Borrower is in compliance with the financial covenant set forth in Article VI of the Credit Agreement.

(vii) No event or events have occurred which individually or in the aggregate could reasonably be expected to have a Material Adverse Effect under the Credit Agreement.

SECTION 6. Governing Law. THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

SECTION 7. Severability of Provisions. Any provision of this Amendment held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 8. Counterparts. This Amendment may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

SECTION 9. Headings. Article and section headings used herein are for convenience of reference only, are not part of this Amendment and shall not affect the construction of, or be taken into consideration in interpreting, this Amendment.
