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) Amended to include the following footnote: The reporting person and spouse made gifts of limited partnership interests in Indian Creek Holdings, Ltd. (the "Limited Partnership") to trusts for the benefit of the reporting person's children (the "Trusts"). The Limited Partnership contains numerous and diverse assets in addition to the common stock of Apache.
(3) The number of shares reported herein consists of (i) an aggregate 9,006 shares held directly by the Trusts and (ii) the number of shares attributable to and held indirectly by the Trusts through the Trusts' ownership interest in the Limited Partnership. The reporting person's children are the beneficiaries of the Trusts, and the reporting person and his spouse are trustees of the Trusts.
(4) These shares are held in trust for the benefit of the reporting person's children. The reporting person and spouse are trustees.
(5) Amended to correct the price and include the following footnote: On June 30, 2009, the reporting person and his spouse sold to the Trusts an aggregate 10.2% limited partnership interest in the Limited Partnership. The Limited Partnership contains numerous and diverse assets in addition to the common stock of Apache, and no separate purchase price was assigned or is attributable to the Apache common stock. The reporting person's beneficial interest and pecuniary interest in the underlying shares of Apache common stock were unchanged by the transaction.
(6) These shares are held by the Limited Partnership. Two entities owned by the reporting person and his spouse are the general partners of the Limited Partnership, and the reporting person, his spouse and the Trusts are the limited partners of the Limited Partnership. These shares do not include the shares attributable to the Trusts' ownership interest in the Limited Partnership that are reported on a separate line.

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