(1)      In addition, pursuant to Rule 416(c) under the Securities Act of 1933,
         this registration statement also covers an indeterminate amount of
         interests to be offered or sold pursuant to the employee benefit plan
         described herein.

(2)      Estimated solely for the purpose of calculating the registration fee.
         Pursuant to Rules 457(c) and 457(h), the offering price and
         registration fee are computed on the basis of the average of the high
         and low prices of the Common Stock, as reported on The New York Stock
         Exchange, Inc. Composite Transactions Reporting System for December 31,
         2002.

(3)      Preferred Stock Purchase Rights are evidenced by certificates for
         shares of the Common Stock and automatically trade with the Common
         Stock. Value attributable to such Preferred Stock Purchase Rights, if
         any, is reflected in the market price of the Common Stock.










This registration statement on Form S-8 is being filed by the registrant, Apache
Corporation ("Apache"), for the purpose of registering an additional 250,000
shares of Apache Common Stock, par value $1.25 per share ("Apache Common
Stock"), for issuance under the terms of the Apache Corporation Executive
Restricted Stock Plan, formerly known as the Apache Corporation Pilot Executive
Restricted Stock Plan and referred to herein as the Plan. Such 250,000 shares of
Apache Common Stock have been reserved and authorized for issuance from the
capital stock held in Apache's treasury. A registration statement on Form S-8
for the initial shares issueable under the plan was filed by Apache on July 31,
2002 and amended by the post-effective amendment no. 1 thereto filed on December
30, 2002. The contents of that initial registration statement, as amended, are
incorporated fully herein by reference.





                                     PART II
               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


CONSENT OF ARTHUR ANDERSEN LLP

         The consolidated financial statements of Apache and its subsidiaries as
of and for the year ended December 31, 2001 incorporated by reference in this
registration statement have been audited by Arthur Andersen LLP, independent
public accountants, as indicated in their reports with respect thereto, and are
included herein in reliance upon the authority of said firm as experts in giving
said reports. Arthur Andersen LLP has not consented to the inclusion of their
report in this registration statement, and Apache has dispensed with the
requirement to file their consent in reliance upon Rule 437a of the Securities
Act of 1933. Because Arthur Andersen LLP has not consented to the inclusion of
their report, you will not be able to recover against Arthur Andersen LLP under
Section 11 of the Securities Act of 1933 for any untrue statements of a material
fact contained in the financial statements audited by Arthur Andersen LLP or any
omissions to state a material fact required to be stated therein.

ITEM 9. UNDERTAKINGS.

(a)      The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

         (i) To include any prospectus required by section 10(a)(3) of the
         Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
         effective date of the registration statement (or the most recent
         post-effective amendment thereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in the registration statement;

         (iii) To include any material information with respect to the plan of
         distribution not previously disclosed in the registration statement or
         any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (4) That, for purposes of determining any liability under the
Securities Act of 1933, each filing of the Registrant's annual report pursuant
to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement relating to the
securities offered herein shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (5) That, for purposes of determining any liability under the
Securities Act of 1933, the information omitted from the form of prospectus
filed as part of this registration statement in reliance upon Rule 430A and
contained in a form of prospectus filed by the registrant pursuant to Rule
424(b)(1) or (4), or 497(h) under the Securities Act of 1933 shall be deemed to
be part of this registration statement as of the time it was declared effective.

         (6) That, for the purpose of determining any liability under the
Securities Act of 1933, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.


                                     II - 3





(b) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933 and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of such issue.


                                     II - 4





                                   SIGNATURES

The Registrant. Pursuant to the requirements of the Securities Act of 1933, the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized in the City of Houston, State of Texas.
