                                PROXY STATEMENT

GENERAL

This proxy statement contains information about the 2003 annual meeting of
stockholders of Apache Corporation. In this proxy statement "Apache" and "the
Company" both refer to Apache Corporation. This proxy statement and the enclosed
proxy card are being mailed to you by the Company's board of directors starting
on or about March 31, 2003.

PURPOSE OF THE ANNUAL MEETING

At the Company's annual meeting, stockholders will vote on the election of
directors as outlined in the accompanying notice of meeting, and on any other
business that properly comes before the meeting. As of the date of this proxy
statement, the Company is not aware of any business to come before the meeting
other than the election of directors. There are no rights of appraisal or
similar rights of dissenters arising from matters to be acted on at the meeting.

WHO CAN VOTE

Only stockholders of record holding shares of Apache common stock at the close
of business on the record date, March 12, 2003, are entitled to receive notice
of the annual meeting and to vote the shares of Apache common stock they held on
that date. As of March 12, 2003, there were 153,867,875 shares of Apache common
stock issued and outstanding. Holders of Apache common stock are entitled to one
vote per share and are not allowed to cumulate votes in the election of
directors. The enclosed proxy card shows the number of shares that you are
entitled to vote.

Apache currently has outstanding one series of preferred stock -- the 5.68%
Cumulative Preferred Stock, Series B (the "Series B Preferred Stock"). The
holders of the depositary shares, each representing 1/10th of a share of Series
B Preferred Stock, are not entitled to any voting rights, except under certain
circumstances relating to non-payment of dividends on the Series B Preferred
Stock. As of the date of this proxy statement, all dividend payments on the
Series B Preferred Stock were current.

HOW TO VOTE

If your shares of Apache common stock are held by a broker, bank or other
nominee (in "street name"), you will receive instructions from them on how to
vote your shares.

If you hold shares of Apache common stock in your own name (as a "stockholder of
record"), you may give instructions on how your shares are to be voted by:

     - marking, signing, dating and returning the enclosed proxy card in the
       postage-paid envelope provided.

     - using the toll-free telephone number or Internet voting site listed on
       the enclosed proxy card. Specific directions for using the telephone and
       Internet voting systems are shown on the proxy card.

                                        1


When using telephone or Internet voting, the systems verify that you are a
stockholder through the use of a company number for Apache and a unique control
number for you. IF YOU VOTE BY TELEPHONE OR INTERNET, PLEASE DO NOT MAIL THE
ENCLOSED PROXY CARD.

Whichever of these methods you use to transmit your instructions, your shares of
Apache common stock will be voted as you direct. If you sign and return the
enclosed proxy card or otherwise designate the proxies named on the proxy card
to vote on your behalf, but do not specify how to vote, your shares will be
voted FOR the election of the nominees for director. If other matters of
business not presently known are properly raised at the meeting, the proxies
will vote on the matters in accordance with their best judgment.

VOTING 401(k) PLAN SHARES

If you are an employee or former employee participating in the Apache 401(k)
Savings Plan and have shares of Apache common stock credited to your plan
account as of the record date, such shares are shown on the enclosed proxy card
and you have the right to direct the plan trustee regarding how to vote those
shares. The trustee for the 401(k) plan is Fidelity Management Trust Company.

The trustee will vote the shares in your plan account in accordance with your
instructions. If you do not send instructions (by voting your shares as provided
above under "How to Vote") or if your proxy card is not received by April 29,
2003, the shares credited to your account will be voted by the trustee in the
same proportion as it votes shares for which it did receive timely instructions.

REVOKING A PROXY

You may revoke a proxy before it is voted by submitting a new proxy with a later
date (by mail, telephone or Internet), by voting at the meeting, or by filing a
written revocation with Apache's corporate secretary. Your attendance at the
annual meeting will not automatically revoke your proxy.

QUORUM AND VOTES NEEDED

The presence at the annual meeting, in person or by proxy, of the holders of a
majority of the shares of Apache common stock outstanding on the record date
will constitute a quorum, permitting the business of the meeting to be
conducted. The affirmative vote of a plurality of the votes cast at the annual
meeting is required for the election of directors.

HOW THE VOTES ARE COUNTED

Representatives of Wells Fargo Bank Minnesota, N.A. will tabulate the votes and
act as inspectors of election. A properly signed proxy marked to "withhold"
authority for the election of one or more directors will be counted for quorum
purposes but not for voting purposes. If a broker indicates on a proxy that they
do not have discretionary authority to vote certain shares of Apache common
stock on a matter, those shares will not be considered present and entitled to
vote at the meeting.

                             ELECTION OF DIRECTORS
                         (PROPOSAL NO. 1 ON PROXY CARD)

The Company's bylaws provide that the board of directors shall consist of a
minimum of seven and a maximum of 13 directors. The Company's certificate of
incorporation provides that, as near as numerically possible, one-third of the
directors shall be elected at each annual meeting of stockholders. Unless
directors earlier resign or are removed, their terms are for three years, and
continue thereafter until their successors are elected and qualify as directors.

The present terms of directors Frederick M. Bohen, George D. Lawrence, Rodman D.
Patton, Charles J. Pitman and Jay A. Precourt will expire at the 2003 annual
meeting. Mr. Precourt was appointed by the board of directors in February 2003,
to succeed Mary Ralph Lowe who resigned from the board effective December 19,
2002, after six years of service.

Mr. Bohen, Mr. Lawrence, Mr. Patton, Mr. Pitman and Mr. Precourt have been
recommended by the Company's nominating committee and nominated by the board of
directors for election by the stockholders to an additional three-year term. If
elected, Mr. Bohen, Mr. Lawrence, Mr. Patton, Mr. Pitman and Mr. Precourt will
serve beginning upon election until the annual meeting of stockholders in 2006.

Unless otherwise instructed, all proxies will be voted in favor of these
nominees. If one or more of the nominees is unwilling or unable to serve, the
proxies will be voted only for the remaining named nominees. Proxies cannot be
voted for more than five nominees. The board of directors knows of no nominee
for director who is unwilling or unable to serve.

The audit committee reviews with the independent accountants and internal
auditors of the Company their respective audit and review programs and
procedures, and the scope and results of their audits. It also examines
professional services provided by the Company's independent accountants and
evaluates their costs and related fees. Additionally, the audit committee
reviews the Company's financial statements and the adequacy of the Company's
system of internal accounting controls. The audit committee makes
recommendations to the board of directors concerning the Company's independent
accountants and their engagement or discharge.

During 2002, the board of directors reviewed the composition of the audit
committee pursuant to the rules of The New York Stock Exchange, Inc. (the
"NYSE") governing audit committees. Based on this review, the board of directors
confirmed that all members of the audit committee are "independent" under the
NYSE's rules. During 2000, the audit committee adopted a charter, which was
approved by the board of directors on May 4, 2000, and which reflects the NYSE's
rules and the regulations of the Securities and Exchange Commission (the "SEC").
No changes were made to the audit committee charter during 2002.

The management development and compensation committee reviews the Company's
management resources and structure, and administers the Company's compensation
programs and retirement, stock purchase and similar plans. The duties of the
stock option plan committee include the award and administration of option
grants under the Company's stock option plans, of grants under the executive
restricted stock plan, of stock unit grants under the deferred delivery plan,
and of conditional grants under the 2000 Share Appreciation Plan.

The executive committee is vested with the authority to exercise the full power
of the board of directors, within established policies, in the intervals between
meetings of the board of directors. In addition to the general authority vested
in it, the executive committee may be vested with specific power and authority
by resolution of the board of directors.

The duties of the nominating committee include recommending to the board of
directors the slate of director nominees submitted to the stockholders for
election at the annual meeting, and proposing qualified candidates to fill
vacancies on the board of directors without regard to race, sex, age, religion
or physical disability.

Stockholders wishing to recommend candidates for consideration by the nominating
committee should forward written recommendations, together with appropriate
biographical information and details of qualifications, to Apache's corporate
secretary. In order to be considered, recommendations must be received by the
deadline for submitting stockholder proposals set forth under the heading
"Stockholder Proposals."

                         REPORT OF THE AUDIT COMMITTEE

To the Board of Directors of Apache Corporation:

We have reviewed and discussed with management the Company's audited financial
statements as of and for the year ended December 31, 2002.

We have received Ernst & Young LLP's letter and discussed with them the matters
required by Statement on Auditing Standards No. 61, Communications with Audit
Committees, as amended, by the Auditing Standards Board of the American
Institute of Certified Public Accountants.

We have received and reviewed the written disclosures from Ernst & Young LLP
required by Independence Standards No. 1, Independence Discussions with Audit
Committees, as amended, by the Independence Standards Board, and have discussed
with the Company's independent auditors their independence.

Based on the reviews and discussions referred to above, we recommended to the
Company's Board of Directors that the financial statements referred to above be
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2002.

March 11, 2003                           Members of the Audit Committee

                                         Randolph M. Ferlic, Chairman
                                         Eugene C. Fiedorek
                                         F. H. Merelli
                                         Rodman D. Patton

                             DIRECTOR COMPENSATION

Employee directors do not receive additional compensation for serving on the
board of directors or any committee of the board. During 2002, non-employee
directors received an annual retainer of $30,000, of which $10,000 in value was
paid in the form of shares of Apache common stock; plus $1,000 for each board of
directors or committee meeting attended, together with reimbursement of expenses
incurred in attending meetings. Non-employee directors receive an annual
retainer of $2,000 for each committee of which they are members. In addition,
the chairman of each committee receives $4,000 annually for chairing their
respective committees.

Under the terms of the Company's non-employee directors' compensation plan, as
amended in 1998, non-employee directors can elect to defer receipt of all or any
portion of their retainers or meeting attendance fees and, subject to certain
parameters, can defer those amounts in the form of cash or in the form of shares
of Apache common stock. Amounts deferred in the form of cash accrue interest
equal to the Company's rate of return on its short-term marketable securities;
amounts deferred in the form of Apache common stock accrue dividends as if the
stock were issued and outstanding when such dividends were payable. All deferred
amounts, as well as accrued interest and dividends, are maintained in a separate
memorandum account for each participating non-employee director. Amounts are
paid out in cash and/or shares of common stock, as applicable, upon the
non-employee director's retirement or other termination of his or her
directorship, or on a specific date, in a lump sum or in annual installments
over a ten-year (or shorter) period. Three non-employee directors deferred all
or a portion of their fees during 2002.

                                        9


An unfunded retirement plan for non-employee directors was established in
December 1992. The plan is administered by the management development and
compensation committee and pays retired non-employee directors benefits equal to
two-thirds of the annual retainer for a period based on length of service.
Payments are made on an annual basis, for a maximum of ten years, and are paid
from the general assets of the Company. In the event of the director's death
prior to receipt of all benefits payable under the plan, the remaining benefits
are payable to the director's surviving spouse or designated beneficiary until
the earlier of the termination of the payment period or the death of the
surviving spouse or designated beneficiary. During 2002, benefits were paid
under this plan to, or on behalf of, five former directors who retired from the
Company's board of directors during 1997, 1998, 2000 and 2001.

The Company established an equity compensation plan for non-employee directors
in February 1994, which is administered by the management development and
compensation committee. Each non-employee director was awarded 1,000 restricted
shares of the Company's common stock every five years from July 1, 1994 through
July 1, 2000, with the shares vesting at a rate of 200 shares annually. On May
3, 2001, the plan was amended to provide that on July 1, 2001 and on July 1 of
each third year thereafter through July 1, 2009, each non-employee director will
be awarded 1,000 restricted shares of common stock, with one-third of the shares
vesting annually. Except as noted below, any unvested shares are forfeited at
the time the non-employee director ceases to be a member of the board. The
unvested portion of any award is automatically vested upon retirement or death
while still serving as a member of the board; provided that the non-employee
director (a) is at least 60 years old and has completed at least ten years of
service at the time of retirement, or (b) has completed at least ten years of
service at the time of death. Awards are made from shares of common stock held
in the Company's treasury, and are automatic and non-discretionary. New
non-employee directors will receive awards of 1,000 shares of common stock on
the July 1 next succeeding their election to the board. All shares of common
stock awarded under the plan have full dividend and voting rights. The plan
expires on July 1, 2009, with a maximum of 50,000 shares of common stock (57,750
shares after adjustment for the stock dividends) that may be awarded during the
term of the plan. No awards were made under the plan during 2002.

(6) On December 17, 1998, the Company's board of directors granted a conditional
    stock award to Mr. Farris for a total of 100,000 shares of the Company's
    common stock (115,496 shares after adjustment for stock dividends). The
    award is composed of five periodic installments, commencing on January 1st
    of each of the next five years, and vesting on the fifth anniversary
    following the applicable commencement date (subject to acceleration under
    specific circumstances). To receive each installment, which is payable 40
    percent in cash and 60 percent in stock, Mr. Farris must be employed by the
    Company on the applicable commencement and vesting dates. For December 31,
    2001, the last business day preceding the January 1, 2002 commencement date,
    the per share closing price of the Company's common stock was $49.88;
    ($47.5048 after adjustment); for December 29, 2000, the last business day
    preceding January 1, 2001, the per share closing price was $70.0625
    ($60.6602 after adjustment); and for December 31, 1999, the last business
    day preceding January 1, 2000, the per share closing price was $36.9375
    ($31.9805 after adjustment). Mr. Farris has all voting, dividend and
    liquidation rights for each installment of shares as of the applicable
    commencement date listed below:

      6,667 shares (7,699 shares after adjustment) commencing January 1, 1999,
      vesting January 1, 2004

      13,333 shares (15,399 shares after adjustment) commencing January 1, 2000,
      vesting January 1, 2005

      20,000 shares (23,100 shares after adjustment) commencing January 1, 2001,
      vesting January 1, 2006

      26,667 shares (30,799 shares after adjustment) commencing January 1, 2002,
      vesting January 1, 2007

      33,333 shares (38,499 shares after adjustment) commencing January 1, 2003,
      vesting January 1, 2008

    At year-end 2002, the aggregate number of shares of conditional stock held
    by Mr. Farris was 76,997 shares with a value of $4,179,191 based on the
    closing price of the Company's common stock as of December 31, 2002.

(7) Dollar value of restricted stock units granted during 2002 under the terms
    of the Executive Restricted Stock Plan, based on the closing price of the
    Company's common stock as of the date of grant. Such restricted stock units
    vest ratably over four years and no dividends are paid on such units until
    vested.

    At year-end 2002, the aggregate number of restricted stock units and value,
    based on the closing price of the Company's common stock as of December 31,
    2002, was: Mr. Raymond Plank -- 13,545 units (after adjustment) and
    $735,171; Mr. Farris -- 13,545 units (after adjustment) and $735,171; Mr.
    Roger Plank -- 7,035 units (after adjustment) and $381,833; Ms. Stewart --
    6,090 units (after adjustment) and $330,542; and Mr. Crum -- 5,355 units
    (after adjustment) and $290,649.

             THE MANAGEMENT DEVELOPMENT AND COMPENSATION COMMITTEE
                        REPORT ON EXECUTIVE COMPENSATION

This report is issued by the Management Development and Compensation Committee
of the board of directors to set out the executive compensation policies and
programs of the Company.

The objective of the Company's executive compensation program is to attract and
retain executives capable of leading the Company in a complex, competitive and
changing industry. A capable, highly-motivated senior management is an integral
part of the Company's continued success. The Company's financial performance is
in large part due to the talent and efforts of the Company's executive officers.
The program ties a significant portion of executive compensation to the
Company's success and is primarily comprised of a base salary, an incentive
bonus, and a long-term incentive component.

BASE SALARY

The Committee believes that the most effective way to compete in the executive
labor market is to offer executives a competitive base salary. To achieve this
balance, the Committee analyzes each executive's compensation using a four-step
process. First, the key executive positions within the Company are defined in
terms of scope and responsibility, job complexity, knowledge and experience
required, and other relevant factors. Second, the positions are ranked
internally on the basis of these definitions to establish a logical relationship
among them. Third, the Committee identifies the Company's direct competitors
which it believes share comparable operations, employee composition, and
capitalization, and obtains comparative compensation data about the identified
companies from independent compensation resources. Finally, easily-compared
positions are priced in terms of salary ranges by reviewing the comparative
industry data and other surveys to establish relative salary ranges for all key
executive positions in the Company. Base salaries are targeted to fall at or
above the median of executive salaries paid by comparable companies, and for
2002 they generally correspond to that practice. The Committee reviews the
salary of each of the Company's 17 executive officers, taking into account the
individual's contribution to the Company's success, how well the individual's
responsibilities are fulfilled, the individual's specific performance, growth in
qualifications for the individual's job, and other relevant aspects of
performance.

Base salaries of all executives are generally reviewed every 12 to 24 months.
Salary adjustments are made within updated, market-confirmed salary ranges
according to the Committee's assessment of the executive's individual
performance and the performance of the Company as a whole. However, changes in
the circumstances of a particular executive can prompt an interim compensation
adjustment. The Committee retained the services of an outside compensation
consultant, who was proposed by management and approved by the Committee, to
review the base salaries of the Company's executives and confirm that the
salaries are competitive with those of comparable companies. The review included
comparative data from part, but not all, of the companies comprising the
Secondary Oils Index reflected in the stock performance chart set forth below.
The exclusion from the review of some of the companies in the Index was due to
their integrated operations or operations in diversified industries.

Based on the factors discussed above, plus additional compensation data
available to the Company from other sources, seven of the Company's officers
received increases in compensation during 2002 to reflect market changes and
increased responsibilities, including none of the executives named in the
Summary Compensation Table.

                                        19


INCENTIVE BONUS

Executives, other than the Company's chairman of the board and the Company's
president (separate plan described below), are eligible to receive a cash
incentive bonus tied directly to the Company's achievement of specified
financial, operational and strategic objectives and the executive's personal
achievements. In the early months of the year, the Committee establishes a
listing of corporate objectives based on those submitted by senior management.
The objectives are approved by both the Committee and the full board of
directors and, in 2002, 75 percent of each executive's bonus depended upon the
Company's achievement of these specified objectives. The remaining 25 percent of
the executive's eligible bonus depended upon personal achievements related to
financial strategies, operational improvements, program or project enhancements,
or other objectively determinable criteria. This incentive compensation plan
effectively correlates a large portion of executive compensation to
predetermined corporate objectives and other objectively determinable goals, all
designed to translate into value for the Company's stockholders. Committee
policy provides for bonuses to be targeted at 50 percent of each executive's
base salary and to exceed 50 percent if the Company's performance warrants.

Executive bonuses for 2002 were based on management's achievement during the
year of specific corporate objectives established by the Committee based on
accepted measures of performance in the oil and gas industry including (a)
increases in cash flow and earnings, (b) growth in reserves and production while
maintaining an acceptable ratio of debt to capitalization, and (c) control of
costs throughout the Company. Additionally, the Committee approved twelve
operational, financial and administrative strategic objectives considered
critical to the Company's success and to maximizing stockholder value. The
Company has elected not to detail the individual items within the specified
strategic corporate objectives as disclosure of such information could provide a
competitive advantage to one or more of the Company's peers; however, the
objectives were annualized for incentive purposes and were broad enough to have
potential impact beyond 2002. With the full or partial achievement of eleven of
the twelve specified objectives setting the stage for the Company's successful
year, the Committee recommended and the full board of directors unanimously
approved an incentive bonus payment in excess of the targets set for executive
officers participating in the corporate plan.

The chairman and the president are each eligible to receive a cash incentive
bonus under a separate incentive compensation plan, which functions and is
administered in the same way as the plan described above, except that their
performance goals are tied directly to the Company's annual financial and
operational results, including the performance of the Company's common stock,
all as compared to the results of a group of its peer companies. The goals
include earnings, production, cash flow, reserves and ratio of debt to
capitalization. The Committee determined to pay the chairman and the president
bonuses of 120 percent of their base salaries in recognition of their leadership
and for the Company's performance during 2002.

In addition to the Company's incentive compensation plans, the Committee may
elect to award a special achievement bonus to an executive officer who has
rendered services during the year that substantially exceed those normally
required. Special achievement bonuses (a) reflect the Committee's decision to
reward any executive whose extraordinary effort has substantially benefited the
Company and its stockholders during the year, (b) are awarded only in
exceptional circumstances, and (c) are in amounts relative to the benefit
provided to the Company. No special achievement bonuses were paid during 2002 to
any of the executive officers named in the Summary Compensation Table or to any
of the Company's other executive officers.

                                        20


LONG-TERM INCENTIVES

Long-term incentives in forms relating to the Company's common stock serve to
align the interests of executive officers with the Company's stockholders by
tying a significant portion of each executive's total long-term compensation to
the continued growth of the Company and appreciation of its common stock. No
stock options were granted to any of the executives named in the Summary
Compensation Table during 2002. In lieu of stock options, the Company's
executive officers received grants of restricted stock units under the Company's
Executive Restricted Stock Plan. Grants of stock units covering an aggregate of
92,500 shares of the Company's common stock (97,125 shares adjusted for the
stock dividends) were made in 2002 to the Company's executive officers as a
group, including grants of restricted stock units covering 43,400 shares (45,570
shares adjusted for the stock dividends) made to the Company's officers named in
the Summary Compensation Table presented above. Grants of restricted stock units
to executives are proportionate to each officer's base salary. Individual grants
of restricted stock units are targeted up to one times base salary and vest
ratably over four years.

In October 2000, the Company established the 2000 Share Appreciation Plan, under
which conditional grants were made in December 2000 to essentially all regular,
full time employees in the United States, Canada and Australia, including each
of the executives named in the Summary Compensation Table. The conditional
grants under the 2000 Share Appreciation Plan are intended to provide specific
individual incentives toward achieving (i) significant price appreciation for
the Company's common stock based on attainment of per share price goals of $100,
$120 and $180 (after adjustment for the Company's stock dividends, the price
goals are $87, $104 and $156, respectively) prior to January 1, 2005, and (ii) a
separate goal, not tied to share price, of doubling production per share from
the 2000 level during any quarter ended prior to January 1, 2005. Benefits are
payable under the conditional grants only if one or more of the above-referenced
share price goals and/or production goal are achieved.

In recognition of his past contributions and expected future contributions to
the Company, Mr. Farris, the Company's president, was granted a conditional
stock award in December 1998, for a total of 100,000 shares of the Company's
common stock (115,496 shares after adjustment for the stock dividends). The
award is composed of five periodic installments, commencing on January 1, 1999
and on January 1st of each of the next four years (2000 through 2003). Each
installment vests on the fifth anniversary following the applicable commencement
date (subject to acceleration under specific circumstances), and is payable 40
percent in cash and 60 percent in the form of stock. To receive each
installment, Mr. Farris must be employed by the Company on the applicable
commencement and vesting dates (see footnote 6 to the Summary Compensation Table
presented above). In the event Mr. Farris elects to terminate his employment
with the Company or his employment is terminated for cause, any unvested
installments will be forfeited.

CHIEF EXECUTIVE OFFICER

Raymond Plank, the chairman of the Company's board of directors, was chief
executive officer ("CEO") from 1966 until May 2002. His activities include
direction of Apache's intensive, on-going programs to monitor, analyze and
respond creatively to the changes and new requirements in the oil and gas
industry, and leadership in maintenance of sound business relationships with the
management of many of the nation's large oil and gas companies. These
relationships are important to Apache's strategic alliances and to its
acquisition approach, which emphasizes privately negotiated transactions that
develop and achieve mutual business benefits. Mr. Plank actively participates in
developing the Company's strategies, and has been jointly responsible for

                                        21


the Company's ongoing interest and successful exploration efforts in
international areas such as Egypt, Australia and China.

G. Steven Farris, the Company's president and chief operating officer, became
the Company's CEO in May 2002. His activities include leadership in developing
the Company's strategies, implementing the Company's capital expenditure
programs, and maintenance of sound business relationships with the management of
many of the nation's large oil and gas companies and with the investment
community. Mr. Farris has been jointly responsible for the Company's developing
interest and successful exploration efforts going forward in international areas
such as Egypt, Australia, China and the North Sea. As CEO, he oversees all of
the Company's major business and staff units and guides and develops Apache's
senior management. Reporting directly to Mr. Farris are each of the executive
vice presidents, corporate and regional vice presidents, including the chief
financial officer and the general counsel.

Base salary, incentive bonus and long-term incentives for each of Mr. Plank and
Mr. Farris are determined in the same manner as is the compensation for the
Company's other executive officers and are reflected in the Summary Compensation
Table above. Mr. Plank's last base salary adjustment was effective January 1,
1996, and Mr. Farris' last base salary adjustment was effective May 16, 2001.
Bonuses paid to Mr. Plank and Mr. Farris were based on the Company's 2002
performance, as discussed above. Each of Mr. Plank and Mr. Farris prepares
personal goals in consultation with the Committee and, throughout the year, each
reports to the Committee on his progress toward achievement of those goals. Mr.
Plank's and Mr. Farris' employment agreements are discussed under "Employment
Contracts and Termination of Employment and Change-in-Control Arrangements."

Base salaries during 2002 for Mr. Plank and Mr. Farris were within the
Committee's percentile targets and took into account the following: their active
roles in the Company's management and leadership of successful acquisitions; the
Company's financial performance during 2001; the challenges and expectations for
the Company in 2002, and for Mr. Plank, his role as a Company founder and his 48
years of service as the Company's senior executive officer. As noted above, the
bonuses paid to Mr. Plank and Mr. Farris for 2002 performance represented 120
percent of their base salaries.

OMNIBUS BUDGET RECONCILIATION ACT OF 1993

The Omnibus Budget Reconciliation Act of 1993 ("OBRA") imposes a limit, with
certain exceptions, on the amount that a publicly held corporation may deduct in
any tax year commencing on or after January 1, 1994, for the compensation paid
or accrued with respect to its chief executive officer and its four most highly
compensated executive officers (other than the chief executive officer). In
December 1995, the Internal Revenue Service issued final regulations
implementing the legislation, with the regulations effective as of January 1,
1994. Certain performance-based compensation is specifically exempt from the
limit if it meets the requirements contained in these final regulations. The
Committee continues to review the Company's compensation plans based upon these
regulations and, from time to time, determines what further actions or changes
to the Company's compensation plans, if any, are appropriate.

Grants of stock options made under the Company's 1990 Stock Incentive Plan, 1995
Stock Option Plan and 1998 Stock Option Plan qualify as "performance-based"
under the regulations. The Company's existing incentive compensation plans,
special achievement bonuses, Executive Restricted Stock Plan, 2000 Stock Option
Plan and 2000 Share Appreciation Plan do not

                                        22


currently meet the requirements of the regulations, as the stockholder approvals
necessary for exemption have not been sought. However, these plans operate
similarly to prior plans and are designed to reward the contribution and
performance of employees and to provide a meaningful incentive for achieving the
Company's goals, which in turn enhances stockholder value. While the Committee
cannot predict with certainty how the Company's compensation policies may be
further impacted by OBRA, it is anticipated that executive compensation paid or
accrued pursuant to the Company's compensation plans that do not meet the
requirements of the regulations will not result in any significant loss of tax
deductions in the foreseeable future.

SUMMARY

According to information provided to the Committee by its independent
compensation consultant, the amount of the Company's cash compensation paid to
all of its executive officers during 2002 was competitive and slightly above the
median for comparable companies. As shown on the Performance Graph following
this report, the cumulative total return on the Company's common stock has
substantially equaled or outperformed that of the Dow Jones Secondary Oil Index
over the last five years and has outperformed the Standard & Poor's Composite
500 Stock Index over the last two years. In view of the Company's competitive
performance, the Committee believes that its current executive compensation
policy is successful in providing stockholders with talented, dedicated
executives at competitive compensation levels.

                    EMPLOYMENT CONTRACTS AND TERMINATION OF
                 EMPLOYMENT AND CHANGE-IN-CONTROL ARRANGEMENTS

Mr. Raymond Plank serves the Company under an employment agreement entered into
in December 1975, amended and restated in December 1990 and amended in April
1996. The agreement has an undefined term and is terminable at will by the
Company's board of directors. Mr. Plank's annual compensation under the
agreement is determined by the board of directors, but may not be less than
$450,000. If his service as a director and an executive officer is terminated by
the board of directors, Mr. Plank will serve as advisor and consultant to the
Company for the remainder of his life at annual compensation equal to 50 percent
of his then-current annual compensation and will receive health, dental and
vision benefits for himself, his spouse and his eligible dependents during the
remainder of his life. Pursuant to the agreement and in exchange for
surrendering life insurance coverage, an annuity was purchased for Mr. Plank
that pays $31,500 annually until 2008. Mr. Plank has agreed not to render
service to any of the Company's competitors for the entire period covered by the
agreement. Upon Mr. Plank's death, a total of $750,000 shall be paid (a) to his
designee in equal monthly installments over ten years, or (b) if he has made no
designation, in a lump sum to his estate.

Mr. Farris serves the Company pursuant to an employment agreement, dated June 6,
1988, under which he received an annual salary of $750,000 during 2002. The
agreement has an undefined term and may be terminated by either the Company or
Mr. Farris on 30 days advance written notice. If Mr. Farris' employment is
terminated without cause, or if he terminates his employment within 30 days of a
reduction in his salary without a proportionate reduction in the salaries of all
other Company executives, Mr. Farris will receive, for 36 months thereafter, (a)
an amount equal to his base salary as it existed 60 days prior to termination
and (b) 50 percent of the maximum amount for which he qualified under the
Company's incentive compensation plan, calculated on his base compensation as it
existed 60 days prior to termination. In the event of Mr. Farris' death during
the 36-month period, the amounts described above shall be paid to his heirs or
estate. Mr. Farris has agreed not to render service to any of the Company's
competitors for the term of his employment or, unless he is terminated without
cause, for 36 months thereafter.

On December 17, 1998, Mr. Farris was granted a conditional stock award, the
basic provisions of which are discussed above in the footnotes to the Summary
Compensation Table and under the caption "Long-Term Incentives" in the report on
executive compensation. Under the terms of the agreement for this award, the
vesting of one or more of the five periodic installments is subject to
acceleration under specific circumstances. Those circumstances generally relate
to (a) termination of Mr. Farris' employment other than for cause, (b) his death
or total disability, (c) an individual other than Mr. Raymond Plank or Mr.
Farris becoming the Company's chief executive officer, and (d) merger,
acquisition or other "change-in-control" of the Company.

In addition to the foregoing, the Company has established an income continuance
plan. The plan provides that all officers of the Company, including the officers
named in the Summary Compensation Table, and all employees who have either
reached the age of 40, served the Company for more than ten years, or have been
designated for participation based upon special skills or experience, will
receive monthly payments approximating their monthly income and continued
medical and health benefits from the Company for up to two years, if their
employment is terminated as a result of a "change in control" of the Company, as
defined in the plan.

                          INDEPENDENT PUBLIC AUDITORS

Ernst & Young LLP was the Company's independent public accounting firm for the
fiscal year 2002. Representatives of Ernst & Young will be present at the annual
meeting and will have an opportunity to make a statement if they desire to do so
and to respond to appropriate questions regarding Apache business.

Ernst & Young's audit report on Apache's consolidated financial statements as of
and for the fiscal year ended December 31, 2002 did not contain any adverse
opinion or disclaimer of opinion, nor was it qualified or modified as to
uncertainty, audit scope, or accounting principles.

During Apache's most recent fiscal year ended December 31, 2002, and through the
filing date of this proxy statement, there were no disagreements with Ernst &
Young on any matter of accounting principles or practices, financial statement
disclosure, or auditing scope or procedure, which disagreements, if not resolved
to Ernst & Young's satisfaction, would have caused Ernst & Young to make
reference to the subject matter of the disagreement in connection with their
report; and there were no reportable events, as described in Item 304(a)(1)(v)
of Regulation S-K.

                                        27


During 2002, Ernst & Young provided various services to Apache. During 2001,
these services were provided by Arthur Andersen LLP. The aggregate fees for each
of the following types of services are set forth below:

------------------------------------------------------------------------------------
                                                             
  Audit Services(1)                                   $1,478            $1,460
  Audit-Related Services(2)                           $  351            $  493
  Tax Services(3)                                     $  433            $3,134
  All Other Services(4)                               $1,844            $  750


(1) Audit Services include the annual financial statement audit (including
    required quarterly reviews), subsidiary audits, and other procedures
    required to be performed by the independent auditor to be able to form an
    opinion on the Company's consolidated financial statements. These other
    procedures include information systems and procedural reviews and testing
    performed in order to understand and place reliance on the systems of
    internal control, and consultations relating to the audit or quarterly
    reviews.

(2) Audit-Related Services are assurance and related services that are
    reasonably related to the performance of the audit or review of the
    Company's financial statements or that are traditionally performed by the
    independent auditor. Audit-related services include, among other things, due
    diligence services pertaining to potential business
    acquisitions/dispositions; accounting consultations related to accounting,
    financial reporting or disclosure matters not classified as "Audit
    Services"; assistance with understanding and implementing new accounting and
    financial reporting guidance from rulemaking authorities; financial audits
    of employee benefit plans; agreed upon or expanded audit procedures related
    to accounting and/or billing records required to respond to or comply with
    financial, accounting or regulatory reporting matters; and assistance with
    internal control reporting requirements.

(3) Tax Services include, among other things, tax compliance, tax planning and
    tax advice.

(4) All Other Services are fees for products and services other than those in
    the three categories above. During 2002, the full amount shown relates to
    certain litigation support work commenced prior to Ernst & Young's
    appointment as the Company's auditors. Once these litigation support
    services are completed or no later than May 5, 2004, Ernst & Young will no
    longer be allowed to perform such services for the Company. During 2001, All
    Other Services provided by Arthur Andersen consisted primarily of services
    related to systems implementation in Canada.

The audit committee of the Company's board of directors reviews summaries of the
services provided by Ernst & Young and the related fees, and has taken into
consideration whether the provision of non-audit services by Ernst & Young is
compatible with maintaining auditor independence.

                             STOCKHOLDER PROPOSALS
