Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The shares of common stock of Apache are deemed to also represent certain preferred stock purchase rights ('Rights'). The Rights are not currently exercisable or separately tradable and presently are evidenced by certificates for shares of the common stock. Value attributable to such Rights, if any, is reflected in the market price of the common stock.
(2) Vesting on 09/15/2011 of restricted stock units granted to each of Apache's non-employee directors under 2011 Omnibus Equity Compensation Plan.
(3) This transaction is not a sale. Exempt disposition to issuer of portion of restricted stock units payable in cash upon vesting. The 2011 Omnibus Equity Compensation Plan contained such provision when approved by stockholders in May 2011, and the restricted stock units contained such terms when granted under the terms of such plan. Of the total 948 restricted stock units that vested on 09/15/2011, 60 percent (569 restricted stock units) is payable in Apache common stock and 40 percent (379 restricted stock units) is payable in cash and is characterized in this report as a disposition to the issuer.
(4) One share of Apache common stock for each restricted stock unit.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
