STRUCTURE

     The Board of Directors for Anadarko Petroleum Corporation (the "Company")
is divided into three classes of directors for purposes of election. One class
of directors is elected at each Annual Meeting of stockholders to serve for a
three-year term.

director elected at this Annual Meeting will hold office until the expiration of
his term in 2006. Those directors not up for election this year will continue in
office for the remainder of their terms.

     If a nominee is unavailable for election, then the proxies will be voted

the Board may reduce the number of directors to be elected at the meeting.

The Board has been comprised of a majority of independent directors since the
Company became an independent company in 1986. The Audit Committee and the
Compensation and Benefits Committee have each been comprised entirely of
independent directors since their inception. As a result of the proposed New
York Stock Exchange ("NYSE") rules, the Board appointed an independent
Nominating and Corporate Governance Committee and has adopted written charters
for all three independent committees that provide, among other things, for an
annual self-evaluation. In addition, the Board has adopted (1) a Code of
Business Conduct and Ethics, (2) a Code of Ethics for the Chief Executive
Officer, Chief Financial Officer and Chief Accounting Officer, and (3) Corporate
Governance Guidelines. These documents are included as appendices to this proxy
statement. The documents can also be found on the Company's website at
www.anadarko.com. An Anonymous Reporting Hotline has been established to
facilitate reporting of violations of financial and non-financial policies.

BOARD OF DIRECTORS

     The Board of Directors has ten members. The Board, on the recommendation of
the Nominating and Corporate Governance Committee, has determined that Messrs.
Albert, Barcus, Brown, Bryan, Butler, Geren, Gordon, and Poduska are independent
directors as defined under the Company's Corporate Governance Guidelines. These
directors are also referred to as non-management directors. See page 7 for a
summary of the Corporate Governance Guidelines. Messrs. Allison and Seitz are
management directors.

     The Board met six times in 2002. All of the directors attended all of the
Board meetings held in 2002.

DIRECTORS' CONTINUING EDUCATION

     In March 2003, Messrs. Allison, Bryan, Butler and Seitz attended a seminar
on the "Role of the Board in Risk Oversight: Board Leadership for Turbulent
Times" that was sponsored by the National Association of Corporate Directors.

                                        3


     During 2003, the Company will provide the directors with an education
program on the duties and responsibilities of directors. If a director has not
attended a director seminar prior to the time of the education program, then the
director will be expected to attend the program provided by the Company.

PRESIDING DIRECTOR AT THE NON-MANAGEMENT DIRECTORS' EXECUTIVE SESSIONS

     The non-management directors meet in executive session immediately after
each regularly scheduled quarterly meeting of the Board of Directors. Mr. Gordon
has been elected to preside at these executive sessions. He may be contacted at
anadarkodirector@apcdirector.com or at Anadarko Petroleum Corporation, Presiding
Director, P.O. Box 9178, The Woodlands, Texas 77387-9178.

TRANSACTIONS WITH ENTITIES CONNECTED TO DIRECTORS

     The Company purchases drilling fluids from several companies including
Newpark Drilling Fluids, Inc. ("Newpark"), a subsidiary of Newpark Resources,
Inc. In 2002, the Company paid Newpark and its affiliates and subsidiaries
approximately $10 million. This amount is approximately 3% of Newpark Resources,
Inc.'s 2001 revenues, or approximately 5% of the 2001 revenues attributable to
fluids sales and the engineering segment, reported in the Newpark Resources,
Inc. Form 10-K for the year ended December 31, 2001. The amount paid to Newpark
in 2002 includes amounts paid by Howell Corporation, which the Company acquired
in December 2002. Mr. Bryan, a director of the Company, is Executive Vice
President of Newpark. His position with Newpark is not the result of his
position on the Company's Board of Directors. He receives no compensation from
Newpark based on the business relationship between the Company and Newpark. He
does not hold 5% or more of any outstanding securities of Newpark Resources,
Inc. The Board has determined that Mr. Bryan is an independent director and that
his position with Newpark does not cause a conflict of interest.

DIRECTOR COMPENSATION

     Non-management directors of the Company receive compensation for Board and
committee service. Management directors of the Company receive no compensation
for their service on the Board. The principal components of director
compensation, which a director may elect to receive in cash, common stock or a
combination of both, are as follows:

        (1) an annual Board retainer of $50,000;

        (2) a fee of $1,250 for each Board or committee meeting attended, plus
            expenses related to attendance;

        (3) an annual committee membership retainer of $3,000; and

        (4) an additional annual committee retainer of $3,000 for serving as
            committee chair.

     1998 Director Stock Plan.  Under the 1998 Director Stock Plan, the
directors may grant stock-based awards to non-management directors. The
following grants were made in 2002 and 2003 under the 1998 Director Stock Plan:

     - On July 29, 2002, the directors granted each non-management director an
       option to purchase 5,000 shares of common stock. The option price is the
       fair market value on the date of grant. The options will vest 50% one
       year from the date of grant, and the remaining 50% will vest two years
       from the date of grant. The options granted will expire 10 years from the
       date of grant.

     - On January 30, 2003, the Board made a deferred stock grant equal to
       $14,500 to each non-management director. The deferred stock will be
       distributed in shares when the director terminates. Directors will
       receive dividends on and will be entitled to vote the deferred stock.

Committee, and the Compensation and Benefits Committee shall each conduct its
own annual self-evaluation.

GUIDELINES AND CODES

CORPORATE GOVERNANCE GUIDELINES

     The Board adopted Corporate Governance Guidelines (the "Guidelines") on the
recommendation of the Nominating and Corporate Governance Committee. Under the
Guidelines, the Board or a Board committee must perform the following functions:

     - Oversee the conduct of the Company's business to evaluate whether the
       business is being properly managed.

     - Review and, where appropriate, approve the Company's major financial
       objectives, plans and actions.

     - Review and, where appropriate, approve major changes in, and
       determinations of other major issues respecting the appropriate auditing
       and accounting principles and practices to be used in the preparation of
       the Company's financial statements.

     - Assess major risk factors relating to the Company and its performance,
       and review measures to address and mitigate such risks.

     - Evaluate regularly the performance and approve the compensation of the
       CEO and, with the advice of the CEO, evaluate regularly the performance
       of principal senior executives.

     - Plan for succession of the CEO and monitor management's succession
       planning for other key executives.

     The Guidelines provide that an individual director should offer his or her
resignation in the event the director's principal occupation or business
association changes substantially from the position the director held when
originally invited to join the Board. Also, a director should tender a
resignation in the event there is a substantial conflict of interest between the
director and the Company or the Board and such conflict cannot be resolved to
the satisfaction of the Board. A director is required to retire on the last day
of the calendar year in which he or she reaches 70 years of age.

     The Guidelines provide that a director is deemed to be independent if he or
she does not have a direct or indirect material relationship with the Company or
any of its affiliates or with any senior management member of the Company or any
of its affiliates. A director will not be deemed independent if, within the past
five years, he or she or a family member has been employed by the Company or its
affiliates or employed by the Company's or any of its affiliates' independent
auditor. A director that has a relationship with a significant customer of or
supplier to the Company of nonprofessional services and goods shall not be
deemed to be independent. Also, a director that has a significant relationship
with a paid adviser, consultant or other provider of professional services to
the Company or to any senior management member will not be deemed to be
independent.
                                        7


     Based on the independence standards in the Guidelines, the Board has
determined that each non-management director is independent. The Board also
determined that each member of the Audit, the Compensation and Benefits, and the
Nominating and Corporate Governance Committees is independent. Messrs. Allison
and Seitz are not considered independent directors due to the positions they
hold with the Company.

     A copy of the Corporate Governance Guidelines that has been adopted by the
Board of Directors is attached to this proxy statement as Appendix D.

CODE OF BUSINESS CONDUCT AND ETHICS FOR ALL DIRECTORS, OFFICERS AND EMPLOYEES

     The Board has adopted a Code of Business Conduct and Ethics for all
directors, officers and employees. It is the responsibility of every Company
director, officer and employee to maintain a commitment to high standards of
conduct and ethics. It is the intent of the Code of Business Conduct and Ethics
to inspire continuing dedication to the fundamental principles of honesty,
loyalty, fairness and forthrightness. There shall be no waiver of any part of
this Code for any director or officer except by a vote of the Board of Directors
or a designated Board committee that shall ascertain whether a waiver is
appropriate under all the circumstances. In case a waiver of this Code is
granted to a director or officer, the notice of such waiver shall be posted on
the Company's website at www.anadarko.com.

     A copy of the Code of Business Conduct and Ethics that has been adopted by

CODE OF ETHICS FOR THE CHIEF EXECUTIVE OFFICER, CHIEF FINANCIAL OFFICER AND
CHIEF ACCOUNTING OFFICER

     The Board has also adopted a separate Code of Ethics for the Chief
Executive Officer, Chief Financial Officer and Chief Accounting Officer ("Senior

       without misrepresenting material facts or allowing the officer's
       independent judgment to be subordinated.

     - Respect the confidentiality of information acquired in the course of
       business except when authorized or otherwise legally obligated to
       disclose the information, acknowledging that confidential information
       acquired in the course of business is not to be used for personal
       advantage.

     - Proactively promote ethical behavior among employees at the Company and
       as a responsible partner with industry peers and associates.

     - Maintain control over and responsibly manage all assets and resources
       employed or entrusted to the officer by the Company.

     - Report illegal or unethical conduct by any director, officer or employee
       that has occurred, is occurring or may occur, including any potential
       violations of the Senior Officers' Code or the Code of Business Conduct
       and Ethics.

     There shall be no waiver of any part of the Senior Officers' Code except by
a vote of the Board of Directors or a designated Board committee that shall
ascertain whether a waiver is appropriate under all

                                        8


the circumstances. In case a waiver of the Senior Officers' Code is granted, the
notice of such waiver shall be posted on the Company's website at
www.anadarko.com.

     A copy of the Senior Officers' Code that has been adopted by the Board of
Directors is attached to this proxy statement as Appendix F and is available on
the Company's website at www.anadarko.com.

ANONYMOUS REPORTING HOTLINE

     To facilitate the reporting of violations of financial and/or non-financial
policies, Anadarko has established an Anonymous Reporting Hotline ("Hotline").
Any concerns regarding accounting, internal accounting controls, auditing or
other disclosure matters reported on the Hotline shall be reported to the
Chairman of the Audit Committee, the Chief Governance Officer, the General
Counsel, the Chief Financial Officer, the Chief Accounting Officer and the
manager of Corporate Audit. Any concerns regarding non-financial matters
reported on the Hotline shall be reported to the Chairman of the Nominating and
Corporate Governance Committee, the Chief Governance Officer, the General
Counsel and two applicable Vice Presidents.

     These reports are confidential and anonymous. Procedures are in place to
investigate all reports received by the Hotline, and to take any corrective
action, if necessary. The Board shall be notified of these reports at every
quarterly Board meeting or sooner if necessary.

NO RETALIATION FOR REPORTING

     There shall be no retaliation against any director, officer or employee for
any report made in good faith. However, if the reporting individual was involved
in improper activity the individual may be appropriately disciplined even if he
or she was the one who disclosed the matter to the Company. In these
circumstances, the Company may consider the conduct of the reporting individual
in promptly reporting the information as a mitigating factor in any disciplinary
decision.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Based solely upon a review of Forms 3, 4 and 5 furnished to the Company
during and with respect to its most recently completed fiscal year, the Company
believes that all transactions by reporting persons during 2002 were reported on
a timely basis. A Form 4 was filed late for one transaction for Mr. Allison that
occurred during the 2001 fiscal year. The Form 4 for the 2001 transaction was
filed in 2002.

                             AUDIT COMMITTEE REPORT

     The following report of the Audit Committee of the Company shall not be
deemed to be "soliciting material" or to be "filed" with the SEC, nor shall this
report be incorporated by reference into any filing made by the Company under
the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934,
as amended.

     The Audit Committee of the Board is responsible for independent, objective
oversight of the Company's accounting functions and internal controls over
financial reporting. The Audit Committee is composed of four directors, each of
whom is independent as defined by the NYSE listing standards. The Audit
Committee operates under a written charter approved by the Board of Directors.

     Management is responsible for the Company's internal controls over
financial reporting. The independent auditor is responsible for performing an
independent audit of the Company's consolidated financial statements in
accordance with generally accepted auditing standards in the United States of
America and issuing a report thereon. The Audit Committee's responsibility is to
monitor and oversee these processes.

     KPMG LLP served as the Company's independent auditor during 2002 and was
appointed by the Audit Committee to serve in that capacity for 2003. KPMG LLP
has served the Company since its initial public offering in 1986.
Representatives of KPMG LLP will be present at the annual stockholders' meeting,
will have the opportunity to make a statement, if so desired, and will be
available to respond to appropriate questions from stockholders.

     In connection with these responsibilities, the Audit Committee met with
management and the independent auditor to review and discuss the December 31,
2002 financial statements. The Audit Committee also discussed with the
independent auditor the matters required by Statement on Auditing Standards No.
61 (Communication with Audit Committees).

                                        11


     The Audit Committee also received written disclosures from the independent
auditor required by Independence Standards Board Standard No. 1 (Independence
Discussions with Audit Committees), and the Audit Committee discussed with the
independent auditor that firm's independence.

     The following table presents fees for the audits of the Company's annual
consolidated financial statements for 2002 and 2001 and for other services
provided by KPMG LLP.



                                                                 2002         2001

Audit Fees..................................................  $1,733,000   $1,425,000
Audit-Related Fees..........................................  $  141,000   $  187,000
Tax Fees....................................................  $1,187,000   $  858,000
All Other Fees..............................................  $        0   $        0


     Audit-related fees are primarily for the Company's benefit plan and other
plan audits. Tax fees are primarily for tax compliance and tax consulting
services. The Audit Committee has concluded that the provision of tax services
is compatible with maintaining KPMG LLP's independence.

     Based upon the Audit Committee's review and discussions with management and
the independent auditor, and the Audit Committee's review of the representations
of management and the independent auditor, the Audit Committee recommended that
the Board of Directors include the audited consolidated financial statements in
the Company's Annual Report on Form 10-K for the year ended December 31, 2002,
to be filed with the SEC.

                             EXECUTIVE COMPENSATION

                   COMPENSATION AND BENEFITS COMMITTEE REPORT
                         ON 2002 EXECUTIVE COMPENSATION

     The Compensation and Benefits Committee ("Compensation Committee"), listed
on page 5, is responsible for establishing and administering the executive
compensation programs of the Company. This report describes the compensation
decisions made by the Compensation Committee during 2002 with respect to
Anadarko's executive officers.

COMPENSATION PHILOSOPHY OF THE COMPANY

     Anadarko's executive compensation programs consist primarily of base
salary, performance-based annual bonus and long-term stock incentive plans which
the Company considers essential to attract, retain and reward key personnel.
Collectively, these programs are designed to promote the strategic objectives
that are critical to the long-term success of the Company.

     The Compensation Committee utilizes an independent compensation consultant
to review executive compensation and benefit programs as well as total
compensation levels provided to executive officers. Anadarko's compensation
programs provide executives the opportunity to earn compensation levels within
the top quartile of a select peer group of oil and gas companies, to the extent
that Company and executive performance on a combined and individual basis so
warrants. The peer group consists of energy companies similar in business
operations and comparable in size to Anadarko. Most of these energy companies
are also included in the Dow Jones Oil-Secondary index used for stock price
performance comparison on the Performance Graph on page 18. The Dow Jones
Oil-Secondary index is comprised of specific energy companies representing most
facets of the industry including independent oil and gas companies as well as
those having integrated operations. Not all companies included in the index are
considered comparable to

                                        12


Anadarko with respect to analyzing executive compensation and benefit levels.
This index does, however, provide a meaningful comparison of total stockholder
return against a consistent representation of oil and gas companies with whom
Anadarko competes for investment dollars.

     During 2002, Anadarko changed its compensation philosophy to place slightly
more emphasis on annual incentive opportunity and lessen reliance on stock based
programs. The Company believes this change is appropriate given that awards
under the Annual Incentive Plan are based on reserve replacement, cost of
finding and relative total shareholder return measures that are all evaluated
from a long-term perspective. Additionally, Anadarko has maintained aggressive
stock ownership guidelines for its executive group since 1993. Anadarko believes
the program has accomplished the desired objective of requiring our executives
to acquire and maintain, for the duration of their careers, a significant
position in Anadarko stock.

BASE SALARY

     Anadarko structures its compensation programs to match pay with
performance. Individual base salaries are determined based on a subjective
evaluation considering peer-company market data, the executive's performance and
the length of time the executive has been in the position. Base compensation is
reviewed annually by the independent compensation consultant and the
Compensation Committee and adjustments, if any, are designed to reflect each
executive officer's contribution to the performance of the Company. In 2002, the
Compensation Committee approved base salary increases for the Company's
officers, including all of the executives named in the Summary Compensation
Table.

ANNUAL INCENTIVE BONUS

     The Annual Incentive Plan puts a significant portion of total compensation
at risk by linking potential annual compensation to the Company's achievement of
specific performance goals. These goals are established by the Compensation
Committee at the beginning of each calendar year and for 2002 included:

        (1) Operational criteria comparing Anadarko's five-year worldwide
            reserve replacement and five-year worldwide cost of finding against
            the five-year worldwide reserve replacement and five-year worldwide
            cost of finding for a select group of peer companies;

        (2) Financial criteria of net income and cash flow, both of which are
            measured against internal objectives; and

        (3) Stock performance criteria comparing Anadarko's total stockholder
            return for a three-year period against the total stockholder return
            of a select group of peer companies for the same period.

     Each performance goal and its specific criteria are weighted based upon the
relative importance of the goal as determined by the Compensation Committee.

     Under the Annual Incentive Plan, a bonus target is established for each
executive officer based upon a review of the competitive data for that position,
level of responsibility and the position's ability to impact the Company's
success. These individual targets range up to 120% of base salary for the Chief
Executive Officer. Actual bonus awards are based on the Company's achievement of
the performance goals and the executive's individual performance. Individuals
may receive up to 200% of their individual bonus target if the Company
significantly exceeds the specified goals and, conversely, no bonus is paid if
the Company does not achieve a minimum threshold level of performance.

     Based on the Company's overall performance during 2002 against the
specified operational, financial and stock performance goals, the Compensation
Committee approved a bonus of 150% of individual bonus targets for Mr. Seitz and
the executive officers as reflected in the Summary Compensation Table.

                                        13


STOCK PLANS

     The Company makes stock-based awards under the 1999 Stock Incentive Plan to
align the interests of executive officers with those of stockholders. The
Compensation Committee annually reviews competitive market data to determine
appropriate stock awards based on the executive's position and the market value
of the stock. In addition, the Compensation Committee considers target
compensation and previous stock grants when determining grant size for executive
officers. The Compensation Committee typically grants stock options, which only
produce value to the holder through the appreciation of the stock. Periodically,
the Compensation Committee makes awards of restricted stock on a limited basis
to recognize significant key individual contributions and to encourage
retention.

     In 2002, Mr. Seitz was elected President and Chief Executive Officer. In
recognition of his election and his expected future contributions to the success
of the Company, the Compensation Committee awarded stock options to Mr. Seitz.
There were no other stock options awarded to any named executive officers.
During 2002, two individuals received stock option grants in recognition of
their election to executive officer positions. The Compensation Committee also
made awards of restricted stock to three named executive officers in recognition
of their contributions and to encourage retention. The number of options granted
to Mr. Seitz, along with special restricted stock awards, are reflected in the
Summary Compensation Table.

SUMMARY

     The Compensation Committee believes the design of the Company's total
executive compensation program provides executives the incentive to maximize
long-term operational performance using sound financial controls and high
standards of integrity. It is the Compensation Committee's belief that this
focus will continue to be reflected in Anadarko's operational, financial and
stock price performance. The Compensation Committee also believes that total
compensation for each executive should be commensurate with the achievement of
specific short-term and long-term operational, financial and strategic
objectives. Accordingly, Mr. Seitz's total compensation for 2002 was within the
top quartile of the peer companies as a result of Anadarko's overall
performance.

     In designing the Company's compensation programs, the Compensation
Committee's primary consideration is Anadarko's achievement of strategic
business goals that serve to enhance shareholder value. Consideration is also
given to competitive practice, market economics and other factors. Section
162(m) of the Internal Revenue Code, as amended (the "Code"), limits a company's
ability to deduct compensation paid in excess of $1 million during any fiscal
year to the Chief Executive Officer and the next four highest paid officers,
unless the compensation meets shareholder approved performance-based
requirements. Awards under the Annual Incentive Plan and the 1999 Stock
Incentive Plan satisfy the performance-based requirements under section 162(m).
The Compensation Committee is committed to making awards that qualify as
deductible compensation under section 162(m) of the Code whenever possible.
However, where granting awards is consistent with the strategic goals of the
Company, the Compensation Committee reserves the right to make awards that are
non-deductible when it believes it is in the best interest of the Company. As a
result of the Company restructuring the components of the executive compensation
program, some bonus awards paid in 2002 were non-deductible.

(1) No Stock Appreciation Rights ("SARs") were granted in 2002. Stock options
    granted on July 2, 2002, were granted under the Company's 1999 Stock
    Incentive Plan. Twenty-five percent (25%) of the options become exercisable
    each year on the anniversary date of the date of grant beginning on July 2,
    2003. In the event of a change of control, any outstanding options will
    automatically vest. The Board may also take any one or more of the following
    actions: (i) provide for the purchase of any outstanding awards by the
    Company; (ii) make adjustments to any outstanding awards; or (iii) allow for
    the substitution of any outstanding awards by the acquiring company's stock.

(2) The exercise price equals the fair market value of the common stock on the
    date of grant.

(3) The dollar amounts under these columns are the results of calculation at 0%
    and at the 5% and 10% rates set by the SEC and are not intended to forecast
    possible future appreciation, if any, of the Company's stock price. The
    Company did not use an alternative formula for a grant date valuation as the
    Company is not aware of any formula which will determine with reasonable
    accuracy a present value based on future unknown or volatility factors.

                               PENSION PLAN TABLE

     The Company has a defined benefit retirement plan that covers all United
States employees and does not require employee contributions. The Retirement
Plan provides benefits based on a formula that considers length of service and
final average pay. For this purpose, "pay" or remuneration generally includes
the amounts shown in the Salary and Bonus columns of the Summary Compensation
Table. The following table reflects the estimated single life annuity payable
annually at normal retirement at age 65 in specified remuneration and
years-of-service classifications, based on the benefit formula in effect on
December 31, 2002.

     Messrs. Allison, Seitz, Rose, Manley and Sullivan, respectively, have 29,
25, 25, 29 and 21 years of accrued service under the Plan. An employee becomes
vested in his or her benefit under the Retirement Plan at completion of five
years of vesting service as defined in the Retirement Plan.

     A portion of the benefits shown in the table may be paid from the Company's
Supplemental Retirement Restoration Plan, rather than from the Retirement Plan,
due to limitations imposed by the Internal Revenue Code that restrict the amount
of benefits payable under tax-qualified plans.

                          TRANSACTIONS WITH MANAGEMENT

CHANGE OF CONTROL ARRANGEMENTS

     The Company has entered into key employee change of control contracts with
each of the named executive officers and with certain other key executives.
These severance contracts have an initial three-year term that is automatically
extended for one year upon each anniversary, unless a notice not to extend is
given by the Company. If a change of control of the Company (as defined below)
occurs during the term of the severance contract, then the contract becomes
operative for a fixed three-year period. The severance contracts generally
provide that the executive's terms and conditions of employment (including
position, work location, compensation and benefits) will not be adversely
changed during the three-year period after a change of control of the Company.
If the Company terminates the executive's employment

                                        18


(other than for cause, death or disability), the executive terminates for good
reason during such three-year period, or the executive terminates employment for
any reason during the 30-day period following the first anniversary of the
change of control, and upon certain terminations prior to a change of control or
in connection with or in anticipation of a change of control, the executive is
generally entitled to receive the following payment and benefits:

        (i)  earned but unpaid compensation;

        (ii)  up to 2.9 times the executive's base salary plus annual bonus
              (based on historic annual bonus);

        (iii)  the Company matching contributions which would have been made had
               the executive continued to participate in the Anadarko Employee
               Savings Plan and the Savings Restoration Plan for up to an
               additional three years;

        (iv)  the value of any investments credited to the executive under the
              Savings Restoration Plan; and

        (v)  the present value of the accrued retirement benefit under the
             Retirement Restoration Plan and the additional retirement benefits,
             including retiree medical, which would have been received had the
             executive continued service for up to an additional three years.

     In addition, the severance contract provides for a continuation of various
medical, dental, disability and life insurance plans and financial counseling
for a period of up to three years, outplacement services and the payment of all
legal fees and expenses incurred by the executive in enforcing any right or
benefit provided by the severance contract. The severance contract also provides
that the executive is entitled to receive a payment in an amount sufficient to
make the executive whole for any excise tax on excess parachute payments imposed
under Section 4999 of the Internal Revenue Code.

     As a condition to receipt of these severance benefits, the executive must
remain in the employ of the Company and render services commensurate with his or
her position until the executive is terminated pursuant to the provisions of the
agreement. The executive must also agree to retain in confidence any and all
confidential information known to him or her concerning the Company and its
business so long as the information is not otherwise publicly disclosed. As of
the date of this proxy statement, no amounts have been paid under the severance
contracts.

     In addition, pursuant to the Company's stock plans, upon a change of
control of the Company (as defined below):

     - Outstanding options and stock appreciation rights that are not vested and
       exercisable become fully vested and exercisable.

     - The restrictions on any outstanding restricted stock lapse.

     - If any performance-based restricted stock awards are outstanding, they
       become fully vested and the performance goals are deemed to be earned
       unless otherwise provided in the participant's award agreement.

     For purposes of the severance contracts and the Company's stock plans, a
change of control is generally defined as:

        (1) Any individual, entity or group acquiring beneficial ownership of
            20% or more of either the outstanding shares of the Company's common
            stock or the combined voting power of the outstanding voting
            securities of the Company entitled to vote generally for the
            election of directors;

        (2) Individuals who constitute the Board on the date hereof cease to
            constitute a majority of the Board, provided that an individual
            whose election or nomination as a director is approved by a vote of
            at least a majority of the directors as of the date hereof will be
            deemed a member of the incumbent Board;

                                        19


          (3) Approval by the Company's stockholders of a reorganization, merger
              or consolidation or sale or other disposition of all or
              substantially all of the assets of the Company or the acquisition
              of assets of another entity, unless following the business
              combination:

           (a) all or substantially all of the beneficial owners of the
               Company's outstanding common stock prior to the business
               combination own more than 60% of the outstanding common stock of
               the corporation resulting from the business combination;

           (b) no person, entity or group owns 20% or more of the outstanding
               voting securities of the corporation resulting from the business
               combination; and

           (c) at least a majority of the board of the corporation resulting
               from the business combination were members of the Company's Board
               prior to the business combination; or

        (4) Approval by the Company's stockholders of a complete liquidation or
            dissolution of the Company.

                              INDEPENDENT AUDITOR

         independent auditor, including major issues regarding accounting,
         disclosure and auditing procedures and practices as well as the
         adequacy of internal controls that could materially affect the
         Company's financial statements. In addition, the review shall include
         the Company's disclosures under "Management's Discussion and Analysis

             independent auditor.

          C. Other material written communications between the independent
             auditor and management, such as any management letter.

      4. Discuss with management the Company's earnings press releases as well

         presentations to be made.

      5. Discuss with management and the independent auditor the effect on the
         Company's financial statements of significant regulatory and accounting
         initiatives as well as off-balance sheet structures.

      6. Discuss with management the Company's major financial risk exposures
         and the steps management has taken to monitor and control such

      7. Review with the independent auditor any audit problems or difficulties
         and management's response, including, but not limited to (1) any
         restrictions on the scope of the auditor's activities, (2) any
         restriction on the access of the independent auditor to requested
         materials, (3) any significant disagreements with management and (4)
         any audit differences that were noted or
                                       A-2


         proposed by the auditor but for which the Company's financial
         statements were not adjusted (as immaterial or otherwise). The
         Committee will resolve any disagreements between the auditors and
         management regarding financial reporting.

      8. Review disclosures made to the Audit Committee by the Company's CEO and
         CFO during their certification process for the Form 10-K and Form 10-Q
         about any significant deficiencies in the design or operation of
         disclosure controls and procedures and any fraud involving management
         or other employees who have a significant role in the Company's
         internal controls.

     11. Obtain quarterly assurances from the senior internal auditing executive
         and management that the system of internal controls is adequate and
         effective. Obtain annually a report from the independent auditor, with
         attestation, regarding management's assessment of the effectiveness of
         the internal control structure and procedures for financial reporting.

   RESPONSIBILITY FOR THE COMPANY'S RELATIONSHIP WITH THE INDEPENDENT AUDITOR

     12. Be solely responsible for the appointment, compensation, retention and
         oversight of the work of the independent auditors employed by the
         Company. The independent auditor shall report directly to the Audit
         Committee. If the appointment of the independent auditors is submitted
         for any ratification by stockholders, the Audit Committee shall be
         responsible for making the recommendation of the independent auditors.

     13. Review, at least annually, the qualifications, performance and
         independence of the independent auditor. In conducting such review, the
         Committee shall obtain and review a report by the independent auditor
         describing (1) the firm's internal quality-control procedures, (2) any
         material issues raised by the most recent internal quality-control
         review, or peer review, of the firm or by any formal investigation by
         governmental or professional authorities regarding services provided by
         the firm which could affect the financial statements of the Company,
         and any steps taken to deal with any such issues, and (3) all
         relationships between the independent auditor and the Company that
         could be considered to bear on the auditor's independence. This
         evaluation shall include the review and evaluation of the lead partner
         of the independent auditor and shall ensure the rotation of partners in
         accordance with Commission rules and the securities laws. In addition,
         the Committee shall consider the advisability of regularly rotating the
         audit firm in order to maintain the independence between the
         independent auditor and the Company.

     14. Approve in advance any audit or permissible non-audit engagement or
         relationship between the Company and the independent auditors. The
         Committee shall establish guidelines for the retention of the
         independent auditor for any permissible non-audit services. The
         Committee hereby delegates to the Chairman of the Committee the
         authority to approve in advance all audit or non-audit services to be
         provided by the independent auditor if presented to the full Committee
         at the next regularly scheduled meeting.

     15. Meet with the independent auditor prior to the audit to review the
         planning and staffing of the audit including the responsibilities and
         staffing of the Company's internal audit department personnel who will
         assist in the audit.

     16. Recommend to the Board policies for the Company's hiring of employees
         or former employees of the independent auditor who participated in any
         capacity in the audit of the Company.

                                       A-3

     17. Review the appointment and replacement of the senior internal auditing
         executive.

     18. Review the activities and organizational structure of the internal
         auditing department and the significant reports to management prepared
         by the internal auditing department and management's responses.

     19. Discuss with the independent auditor and management the internal audit
         department responsibilities, budget and staffing and any recommended

             ADOPTED BY THE BOARD OF DIRECTORS ON JANUARY 30, 2003

ROLE AND FUNCTIONS OF THE BOARD OF DIRECTORS

     The role of the Board of Directors (the "Board") is to oversee and monitor
the Company's management in the interest and for the benefit of the Company's
stockholders. To fulfill its role the Board or a Board committee must perform
the following primary functions:

        1. oversee the conduct of the Company's business to evaluate whether the
           business is being properly managed;

        2. review and, where appropriate, approve the Company's major financial
           objectives, plans and actions;

        3. review and, where appropriate, approve major changes in, and
           determinations of other major issues respecting the appropriate
           auditing and accounting principles and practices to be used in the
           preparation of the Company's financial statements;

        4. assess major risk factors relating to the Company and its
           performance, and review measures to address and mitigate such risks;

        5. evaluate regularly the performance and approve the compensation of
           the CEO and, with the advice of the CEO, evaluate regularly the
           performance of principal senior executives; and

        6. plan for succession of the CEO and monitor management's succession
           planning for other key executives.

     In discharging these obligations, directors should be entitled to rely
reasonably on the honesty and integrity of their fellow directors and the
Company's executives and its outside advisors and auditors. The directors shall
be entitled to (i) have the Company purchase reasonable directors' and officers'
liability insurance on their behalf; (ii) the benefits of indemnification to the
fullest extent permitted by law under the Company's charter, by-laws and any
indemnification agreements; and (iii) exculpation as provided by state law and
the Company's charter.

     The Board may discharge its responsibilities either directly or by
delegating them to its committees, except that the Board may not delegate any of
its responsibilities which, under applicable law or the Company's restated
certificate of incorporation, may not be delegated to a committee of the Board.
The Board and each Board committee shall have the full power and authority to
hire, at the expense of the Company, independent financial, accounting, legal or
other advisors, as necessary to fulfill their duties, without consulting or
obtaining the approval of any officer of the Company.

     The Board should promote policies within the Company that encourage a
corporate culture of openness, honesty, fairness and accountability. These
policies also should apply to the Board and to relationships among and between
the Board, stockholders and employees. The Board should periodically review and
amend these policies if needed.

     The Board should recognize that the actual management of the business and
affairs of the Company should be conducted by the CEO and other senior managers
under his or her supervision and that, in performing the management function,
the CEO and other senior managers are obliged to act in a manner that is
consistent with the oversight functions and powers of the Board and the
standards of the Company and to execute any specific plans, instructions or
directions of the Board.

                                       D-1


DIRECTOR QUALIFICATIONS

     Independence:  The Board shall have a majority of directors who meet the
independence criteria adopted by the Board. The independence criteria are
discussed below under "Director Independence."

     Qualifications:  A director should possess personal and professional
integrity, have good business judgment, relevant experience and skills and be an
effective director in conjunction with the full Board in collectively serving
the long-term interests of the Company stockholders. Directors should be
committed to devoting sufficient time and energy to diligently performing their
duties as directors.

     Size of Board:  The Board shall determine the appropriate size of the Board
within the requirements of the Company's Charter and Bylaws.

     Selection Process:  In accordance with the policies and principles in its
charter, the Nominating and Corporate Governance Committee is responsible for
identifying and recommending potential director nominees to the Board for its
approval when there is a vacancy on the Board. The Chairman of the Nominating
and Corporate Governance Committee and the Chairman of the Board shall extend an
invitation to the potential director nominee to join the Board.

     Annual Review of Independence and Qualifications:  The Nominating and
Corporate Governance Committee shall distribute annually a self-evaluation to
the Board that includes an assessment of the directors' independence and
qualifications.

     Resignation from the Board:  An individual director should offer his or her
resignation in the event the director's principal occupation or business
association changes substantially from the position he or she held when
originally invited to join the Board. The Board should consider the continued
appropriateness of the director's membership on the Board under the changed
circumstances and then the Board should determine whether or not to accept the
director's resignation. Also a director should tender a resignation in the event
there is a substantial conflict of interest between the director and the Company
or the Board and such conflict cannot be resolved to the satisfaction of the
Board.

     Retirement from the Board:  A director shall retire from the Board at the
end of the calendar year in which he or she reaches 70 years of age.

     Recusal when Conflict of Interest:  Prior to any Board discussion or
decision related to any matter that potentially affects a director's personal,
business or professional interests, that director should (i) disclose the
existence of the potential conflict of interest to the Chairman of the Board and
(ii) if the Chairman of the Board (in consultation with legal counsel)
determines a conflict exists or the perception of a conflict is likely to be
significant, recuse himself or herself from any discussion or vote related to
the matter.

     Limit on Number of Board Memberships:  No director may serve on more than
three other public company boards. A director should advise the Chairman of the
Board and the Chairman of the Nominating and Corporate Governance Committee in
advance of accepting an invitation to serve on another public company board.

     Term Limits:  The Board does not believe it should establish term limits.
The Company and its stockholders both benefit from Board continuity and
stability and by allowing directors to focus on long-term business strategies
and results.

DIRECTOR INDEPENDENCE

     A substantial majority of the Board and all members of the Audit, the
Compensation and Benefits, and the Nominating and Corporate Governance
Committees shall be independent. The Board must make an affirmative
determination whether or not a director is independent and disclose this
determination in the annual proxy statement.

     The term independent is defined in accordance with the proposed New York
Stock Exchange ("NYSE") independence requirements, the Sarbanes-Oxley Act and
the Board's business judgment. A
                                       D-2


director is deemed to be independent if he or she does not have a direct or
indirect material relationship with the Company or any of its affiliates or with
any senior management member of the Company or any of its affiliates. In
determining the materiality of a relationship and the director's independence,
the Board shall be guided by the following independence standards:

     A director shall be deemed to have a material relationship with the Company
and/or its affiliates and thus shall not be deemed independent if, within the
past five years:

     - The director is or has been employed by the Company or its affiliates;

     - An immediate family member (defined below) of the director is or has been
       employed by the Company or any of its affiliates as an officer;

     - The director is or has been affiliated with or employed by the Company's
       or any of its affiliate's present or former independent auditor;

     - An immediate family member of the director is or has been employed by the
       Company's or any of its affiliate's present or former independent auditor
       as a partner, principal or manager; or

     - An executive officer of the Company serves on the compensation committee
       of a company which employs the director, or which employs an immediate
       family member of the director as an officer.

     Other material relationships in which the director shall not be deemed to
be independent are:

     - The director or an immediate family of the director is a director,
       officer, general partner or large equity holder of a significant customer
       of or supplier to the Company and/or its affiliates of nonprofessional
       services and goods;

     - The director or an immediate family member of the director is a director,
       officer, general partner or large equity holder of a significant paid
       adviser, paid consultant or other paid provider of professional services
       to the Company or its affiliates, or to any senior management member of
       the Company; or

     - The director or an immediate family member of the director is a director,
       officer or trustee of a charitable or tax-exempt organization to whom the
       Company, one of its affiliates or any senior management member of the
       Company or its affiliates makes substantial charitable contributions.

     In the following circumstances, the material relationships shall be deemed
immaterial and thus the director shall remain independent:

     - A director who serves as an Interim Chairman or Interim CEO of the
       Company shall not be deemed a former employee for the purpose of
       determining independence and as such, the director shall retain his
       independent status when his service as Interim Chairman or Interim CEO
       ends;

     - The material relationship that is based on having an immediate family
       member of the director serving as an officer of the Company or an officer
       of a Company affiliate shall be deemed immaterial upon the death or
       incapacitation of that immediate family member; or

     - The material relationship that is based on the director's or the
       director's immediate family member's connection to a significant
       customer, supplier or provider of the Company or its affiliates shall be
       deemed immaterial, if the Board in its business judgment determines that
       the commercial transactions between the Company or one of its affiliates
       and the significant customer, supplier or provider were conducted at
       arm's length in the ordinary course of business and that such a
       relationship is immaterial in light of all circumstances.

     For any relationships not covered above, the determination of whether these
relationships are material or not and whether the director would be independent
or not, shall be made by the directors who satisfy the independence standards
set forth in this section. In making these determinations, the Board shall
examine all factors that may appear to affect independence, including
commercial, industrial, financial, banking, legal, accounting, charitable,
familial relationships and long-standing friendships.

                                       D-3


     The Company and its affiliates shall not make any personal loans or
extensions of credit to directors or executive officers. All directors shall
only receive directors' fees as their compensation for Board and/or Board
committee service. The payment of consulting, advisory or other compensatory
fees to a director from the Company or one of its affiliates is prohibited and
shall negate the director's independence.

     Each director has an affirmative obligation to inform the Board of any
material changes in his or her circumstances or relationships that may impact
his or her designation by the Board as "independent."

     For the purposes of these independence standards guidelines, the terms:

     - Affiliate means any corporation or other entity that controls, is
       controlled by or is under common control with the Company, as evidenced
       by the power to elect a majority of the Board or comparable governing
       body of such entity;

     - Immediate Family Member includes a person's spouse, parents, children,
       siblings, mothers and fathers-in-law, sons and daughters in-law, brothers
       and sisters in-law, and anyone (other than employees) who shares such
       person's home; and

     - Significant means payments to or from an entity where the payments exceed
       five percent of the entity's annual gross revenues.

BOARD MEETINGS

     The Board expects to have four regularly scheduled meetings each year. Upon
adequate notice, unscheduled meetings may be called throughout the year as the
need arises. The Chairman of the Board shall consult with other Board members in
determining the times and duration of the Board meetings.

     Meeting Attendance:  Directors are expected to attend regularly Board and
committee meetings on which they serve. Directors also are expected to convene
and devote an adequate amount of time and effort to discharge properly their
responsibilities.

     Board Materials:  Information and data that are important to the Board's
understanding of the business to be conducted at a Board or committee meeting
should be distributed in writing to the directors before the meeting if
possible. Directors are expected review these materials in advance of the
meeting. A director may request that the CEO or appropriate member of senior
management present to the Board specific information as it relates to the
Company and its operations.

     Board Meeting Agenda:  The Chairman of the Board shall establish the agenda
for each Board meeting. Each director shall be furnished with a copy of the
agenda in advance of the Board meeting if possible, and if advance distribution
is not possible, then the agenda shall be distributed at the Board meeting. Each
director may suggest the inclusion of agenda items. Each director can bring up,
at any Board meeting, subjects that are not on the agenda for that meeting.

     Non-Management Executive Session of Directors:  The non-management
directors shall meet in executive session after each regularly scheduled Board
meeting or more frequently, if necessary. The non-management directors shall
elect a "Presiding Director" to preside at these non-management executive

                                       D-4


sessions. The name of the Presiding Director shall be disclosed in the annual
proxy statement, together with a system for interested parties to communicate
directly with the "Presiding Director."

BOARD COMMITTEES

     The Board shall have at all times an Audit Committee, a Compensation and
Benefits Committee and a Nominating and Corporate Governance Committee. All
members of these Committees shall be independent directors as determined by the
Board in accordance with the aforementioned independence criteria. Committee
members shall be appointed by the Board upon recommendation (after consultation
with the Chairman) of the Nominating and Corporate Governance Committee. In
making any committee appointments, consideration should be given to the periodic
rotation of a committee member; however, such rotation is within the Board's
discretion.

     The Audit Committee, Compensation and Benefits Committee and the Nominating
and Corporate Governance Committee each shall have a written charter that sets
forth the committee's structure, membership qualifications, purposes,
responsibilities, and procedures for appointing and removing committee members.
The charters also shall provide that each committee annually evaluates its
performance.

     Each committee chairman, in consultation with the committee members, shall
determine the frequency and length of the committee meetings consistent with any
requirements set forth in the committee's charter. Each committee chairman, in
consultation with the appropriate members of the committee and management, shall
develop the committee's agenda. Each committee shall report to the Board its
activities, findings and recommendations after each committee meeting.

     The Board may, from time to time, establish or maintain additional
committees of the Board, including an Executive Committee. If an Executive
Committee is established, it will have the powers and authority as specified in
the Company's by-laws.

     Each committee shall have the full power and authority to hire independent
legal, financial or other advisors as it may deem necessary, without consulting
with or obtaining the pre-approval of any Company officer or the Board.

     Any director may attend any committee meetings, whether or not he or she is
a member of that committee, providing that he or she has obtained pre-approval
to attend from the committee chair or a majority of the committee.

CHAIRMAN OF THE BOARD

     The Board will appoint the Chairman of the Board who can be an employee of
the Company. The Chairman will chair all regular sessions of the Board and (with
input from the CEO to the extent not inappropriate) set the agenda for Board
meetings, subject to the right of each Board member to suggest the inclusion of
item(s) on any agenda.

DIRECTOR ACCESS TO OFFICERS, EMPLOYEES AND INDEPENDENT ADVISERS

     Directors are encouraged to keep themselves informed with regard to the
Company and its operations. Directors shall have full and free access to Company
officers and employees. Any meetings or contacts that a director wishes to
initiate may be arranged through the CEO, the Corporate Secretary or directly by
the director. Directors shall use their judgment to ensure that any such contact
is not disruptive to the Company's business operations and shall, to the extent
that it is not inappropriate, copy the CEO on any written communications between
a director and a Company officer or employee.

     The Board shall approve any director's request to have senior Company
officers and other personnel regularly attend the Board meetings. Directors will
also have access to the Company's independent advisors following consultation
with the CEO to the extent not inappropriate.

                                       D-5


DIRECTOR COMPENSATION

     All directors shall receive directors' fees as their only compensation for
Board and/or Board committee service. Directors' fees shall be in the form of
cash, company stock, including options and restricted stock, or combination
thereof, as well as any additional benefits regularly given to all directors.
The exact amount and form of director compensation shall be determined and
reviewed annually by the Compensation and Benefits Committee in accordance with
the policies and principles set forth in its charter.

current calendar year and any other pertinent information. The new director will
attend a meeting with the CEO and Chief Financial Officer to be briefed on the
Company's strategic plans, its significant financial, accounting and risk
management issues and current significant exploration and development projects.

     All directors must receive annual director education in subjects relevant
to the duties of a director, including the study of corporate governance best
practices or ethics. This education may be as a result of a program planned by
the Company or by the director attending a pre-approved seminar, with all
expenses paid by the Company.

CEO EVALUATION AND MANAGEMENT SUCCESSION

     The Compensation and Benefits Committee shall conduct an annual review of
the CEO's performance and compensation, as set forth in its charter. The

Committee's report in order to ensure that the CEO is providing the best long
and short-term leadership for the Company.

     The Nominating and Corporate Governance Committee shall make an annual
report to the Board on emergency as well as expected CEO succession planning.
The entire Board shall work with the Nominating and Corporate Governance
Committee to nominate and evaluate potential successors to the CEO. The CEO

for such individuals.

ANNUAL SELF-EVALUATIONS

     The Nominating and Corporate Governance Committee shall have responsibility
for conducting and overseeing the annual self-evaluations for the Board and
reporting the results to the Board following the end of each fiscal year. The
evaluations will be based on such objective and subjective criteria, as the
Board deems appropriate.

CODE OF BUSINESS CONDUCT AND ETHICS

     The Board shall adopt and maintain the Code of Business Conduct and Ethics
(the "Code") for the directors, officers and employees of the Company in
compliance with the proposed NYSE requirements. The Code shall be posted on the
Company's website. The purpose of the Code shall be to focus the directors,
officers and employees on areas of ethical risk, provide guidance in recognizing
and dealing with ethical issues, provide mechanisms to report unethical conduct,
and help foster a culture of honesty and accountability.

     Each director shall act at all times in accordance with the requirements of
the Code. Waivers of the Code for any officer or director may only be made by
the Board of the Company or by a Board committee composed of independent
directors. Any waiver for an officer or director must be posted on the Company
website and communicated to stockholders.
                                       D-6


REPORTS OF ACCOUNTING CONCERNS

     Any reports of concerns regarding accounting, internal auditing controls or
other audit matters shall be reported to the Chief Governance Officer, the
General Counsel and the Chairman of the Audit Committee. These reports are
confidential and may be anonymous. The Board shall be notified of these reports
at every quarterly Board meeting or sooner, if necessary.

                                       D-7


                                                                      APPENDIX E

                         ANADARKO PETROLEUM CORPORATION

                      CODE OF BUSINESS CONDUCT AND ETHICS
                                  JANUARY 2003

     Anadarko Petroleum Corporation has been built by hard work, prudent
risk-taking and high standards of conduct and ethics. It is the responsibility
of every Anadarko director, officer and employee to maintain our commitment to
these basic principles so that we can continue to provide value to our
stockholders and maintain our reputation. We want to continue to be the kind of
company that can attract and retain the best people in our industry. It is the
intent of this Code of Business Conduct and Ethics to inspire continuing
dedication to the fundamental principles of honesty, loyalty, fairness and
forthrightness that have made Anadarko a leader.

     Please review these policies and return to them for guidance when you are
in doubt as to the right course of conduct. If your questions are not answered
by this Code, STOP; take advantage of the Company's open door policy; and, only
when you are comfortable that your contemplated action complies with high
ethical standards, proceed. We must take responsibility for our own conduct.

     In addition to fulfilling our own duty to the Company, we must protect the
Company from the harmful conduct of others. We must prevent illegal or unethical
practices from taking root in our corporate culture. If we cannot prevent such
practices, we must report the violations to someone that can. Even if the
actions reported are those of our supervisors or managers, if they are illegal
or unethical, they are against the policy of Anadarko. No harassment or
retribution against those who report such actions in good faith will be
tolerated.

     Corporate leaders must set a personal example of honesty, respect and
loyalty. Leaders must help to develop a corporate culture in which openness and
communication is combined with prudent risk-taking and constant improvement of
our business practices. We should learn from our mistakes as well as our
successes.

     Whether interacting with stockholders, board members or employees, or with
customers, suppliers, competitors or the community at large, let the principles
expressed in this Code be your guide. You should represent our Company with
honor, integrity and your best effort. Let us uphold these standards so that the
reputation of Anadarko Petroleum Corporation becomes the standard that other
companies emulate.


                                            
Robert J. Allison, Jr.,                        John N. Seitz,
Chairman                                       President and Chief Executive Officer


                                       E-1


                         ANADARKO PETROLEUM CORPORATION

                      CODE OF BUSINESS CONDUCT AND ETHICS

     OUR CODE APPLIES TO EVERY DIRECTOR, OFFICER (INCLUDING OUR CHIEF EXECUTIVE
OFFICER, CHIEF FINANCIAL OFFICER AND CHIEF ACCOUNTING OFFICER), AND EMPLOYEE OF
ANADARKO PETROLEUM CORPORATION. THE TERM EMPLOYEE INCLUDES ANY INDIVIDUAL THAT
IS PAID ON THE ANADARKO PAYROLL.

     To further the Company's fundamental principles of honesty, loyalty,
fairness and forthrightness, we have established the Anadarko Code of Business
Conduct and Ethics. Our Code strives to deter wrongdoing and promote the
following six objectives:

          1. Honest and ethical conduct;

          2. Avoidance of conflicts of interest;

          3. Full, fair, accurate, timely and transparent disclosure;

          4. Compliance with the applicable government and self-regulatory
             organization laws, rules and regulations;

          5. Prompt internal reporting of Code violations; and

          6. Accountability for compliance with the Code.

     Below, we discuss situations that require application of our fundamental
principles and promotion of our objectives. If there is a conflict between this
Code and a specific procedure you should consult the Legal department for
guidance.

                  ACCOUNTABILITY FOR COMPLIANCE WITH THE CODE

     Each of the Company's directors, officers and employees is expected to:

     Understand.  Anadarko expects YOU to understand the requirements of your
position including Company expectations and governmental rules and regulations
that apply to your position.

     Comply.  Anadarko expects YOU to comply with this Code and all applicable
laws, rules and regulations.

     Report.  Anadarko expects YOU to report any violation of this Code of which
you become aware.

     Accountable.  Anadarko holds YOU accountable for complying with the Code.

                              ACCOUNTING POLICIES

     Anadarko and each of our subsidiaries will make and keep books, records and
accounts, which in reasonable detail accurately and fairly present the
transactions and disposition of the assets of our Company.

     All directors, officers, employees and other persons are prohibited from
directly or indirectly falsifying or causing to be false or misleading any
financial or accounting book, record or account. You and others are expressly
prohibited from directly or indirectly manipulating an audit, and from
destroying or tampering with any record, document or tangible object with the
intent to obstruct a pending or contemplated audit, review or federal
investigation. The commission of, or participation in, one of these prohibited
activities or other illegal conduct will subject the perpetrator to federal
penalties, as well as punishment of up to and including termination of
employment. For more information on our accounting procedures and processes see
the Anadarko Intranet.

     No director, officer or employee of the Company may directly or indirectly:

     - Make or cause to be made a materially false or misleading statement, or

     - Omit to state, or cause another person to omit to state, any material
       fact necessary to make statements made not misleading

in connection with the audit of financial statements by independent accountants,
the preparation of any required reports whether by independent or internal
accountants, or any other work which involves or relates to the filing of a
document with the Securities and Exchange Commission ("SEC").

                   AMENDMENTS AND MODIFICATIONS OF THIS CODE

     There shall be no amendment or modification to this Code except by a vote
of the Board of Directors or a designated board committee that will ascertain
whether an amendment or modification is appropriate.

     In case of any amendment or modification of this Code that applies to an
officer or director of the Company, the amendment or modification shall be
posted on the Company's website within two days of the board vote or shall be
otherwise disclosed as required by applicable law or New York Stock Exchange
rules. Notice posted on the website shall remain there for a period of 12 months
and shall be retained in the Company's files as required by law.

                              ANONYMOUS REPORTING

     If you wish to report a suspected violation of this Code anonymously, you
may call the Anadarko Anonymous Reporting Hotline at 1-877-781-2434. Anadarko
will not disclose the identity of any employee who reports a violation of this
Code without his or her permission, unless disclosure is unavoidable during an
investigation.

                      ANTI-BOYCOTT AND U.S. SANCTIONS LAWS

     We must comply with anti-boycott laws, which prohibit Anadarko from
participating in, and require us to report to the authorities any request to
participate in, a boycott of a country or businesses within a country. If you
receive such a request, report it to the Vice President of your division. We
will also not engage in business with any government, entity, organization or
individual where doing so is prohibited by applicable laws. For more information
on these laws contact the Legal department.

                      ANTITRUST AND FAIR COMPETITION LAWS

     The purpose of antitrust laws in the United States and most other countries
is to provide a level playing field to economic competitors and to promote fair
competition. No director, officer or employee, under any circumstances or in any
context, may enter into any understanding or agreement, whether express or
implied, formal or informal, written or oral, with an actual or potential
competitor, which would

                                       E-4


illegally limit or restrict in any way either party's actions, including the
offers of either party to any third party. This prohibition includes any action
relating to prices, costs, profits, products, services, terms or conditions of
sale, market share or customer or supplier classification or selection.

     It is our policy to comply with all U.S. antitrust laws. This policy is not
to be compromised or qualified by anyone acting for or on behalf of our Company.
You must understand and comply with the antitrust laws as they may bear upon
your activities and decisions. Anti-competitive behavior in violation of
antitrust laws can result in criminal penalties, both for the individual
involved and for the Company. Accordingly, any question regarding compliance
with antitrust laws or your responsibilities under this policy should be
directed to the Legal department. Any director, officer or employee found to
have knowingly participated in violating the antitrust laws will be subject to
disciplinary action, up to and including termination of employment.

     Below are some scenarios that are prohibited and scenarios that could be
prohibited for antitrust reasons. These scenarios are not an exhaustive list of
all prohibited and possibly prohibited antitrust conduct. When in doubt about
any situation, whether it is discussed below or not, you should consult with the
Legal department.

     The following scenarios are prohibited for antitrust or anti-competition
reasons:

     - Proposals or execution of any agreements or understanding -- express or
       implied, formal or informal, written or oral -- with any competitor
       regarding any aspect of competition between Anadarko and the competitor
       for sales to third parties.

     - Proposals or execution of any agreements or understanding with customers
       which restrict the price or other terms at which the customer may resell
       or lease any product to a third party.

     - Proposals or execution of any agreements or understanding with suppliers
       which restrict the price or other terms at which Anadarko may resell or
       lease any product or service to a third party.

     The following business arrangements could raise anti-competition or
antitrust law issues. Before entering into them, you must consult with the Legal
department:

     - Exclusive arrangements for the purchase or sale of products or services.

     - Bundling of goods and services.

     - Technology licensing agreements that restrict the freedom of the licensee
       or licensor.

     - Agreements to add an Anadarko employee to another entity's Board of
       Directors.

                                    BRIBERY

     You are strictly forbidden from offering, promising, or giving money,
gifts, loans, rewards, favors or anything of value to any governmental official,
employee, agent or other intermediary (either inside or outside the United
States) which is prohibited by law. Those paying a bribe may subject the Company
and themselves to civil and criminal penalties. When dealing with government
customers or officials, no improper payments will be tolerated. If you receive
any offer of money or gifts that is intended to influence a business decision,
then it should be reported to your supervisor or the General Counsel
immediately.

     The Company prohibits improper payments in all of its activities, whether
these activities are with governments or in the private sector.

                  COMPLIANCE WITH LAWS, RULES AND REGULATIONS

     Anadarko's goal and intention is to comply with the laws, rules and
regulations by which we are governed. In fact, we strive to comply not only with
requirements of the law but also with recognized compliance practices. All
illegal activities or illegal conduct are prohibited whether or not they are
specifically set forth in this Code.

                                       E-5


     Where law does not govern a situation or where the law is unclear or
conflicting, you should discuss the situation with your supervisor and
management should seek advice from the Legal department. Business should always
be conducted in a fair and forthright manner. Directors, officers and employees
are expected to act according to high ethical standards.

                        COMPUTER AND INFORMATION SYSTEMS

     For business purposes, officers and employees are provided telephones and
computer workstations and software, including network access to computing
systems such as the Internet and e-mail, to improve personal productivity and to
efficiently manage proprietary information in a secure and reliable manner. You
must obtain the permission from the Information Technology Services department
to install any software on any Company computer or connect any personal laptop
to the Company network. As with other equipment and assets of the Company, we
are each responsible for the appropriate use of these assets. Except for limited
personal use of the Company's telephones and computer/e-mail, such equipment may
be used only for business purposes. Officers and employees should not expect a
right to privacy of their e-mail. All e-mails on Company equipment are subject
to monitoring by the Company. Please access the Anadarko Intranet for guidelines
for use of e-mail and Internet services and other related procedures.

                  CONFIDENTIAL INFORMATION BELONGING TO OTHERS

     You must respect the confidentiality of information, including, but not
limited to, trade secrets and other information given in confidence by others,
including but not limited to partners, suppliers, contractors, competitors or
customers, just as we protect our own confidential information. However, certain
restrictions about the information of others may place an unfair burden on
Anadarko's future business. For that reason, directors, officers and employees
should coordinate with the Legal department to ensure appropriate agreements are
in place prior to receiving any confidential third-party information. These
agreements must reflect a balance between the value of the information received
and the logistical and financial costs involved in both maintaining
confidentiality of the information and also limiting Anadarko's business
opportunities. In addition, any confidential information that you may possess
from an outside source, such as a previous employer, must not, so long as such
information remains confidential, be disclosed to or used by Anadarko.
Unsolicited confidential information submitted to Anadarko should be refused,
returned to the sender where possible and deleted, if received via the Internet.

                    CONFIDENTIAL AND PROPRIETARY INFORMATION

     It is Anadarko's policy to ensure that all operations, activities and
business affairs of the Company and our business associates are kept
confidential to the greatest extent possible. Confidential information includes
all non-public information that might be of use to competitors, or that might be
harmful to the Company or its customers if disclosed. Confidential and
proprietary information about Anadarko or its business associates belongs to the
Company, must be treated with strictest confidence and is not to be disclosed or
discussed with others.

     Unless otherwise agreed to in writing, confidential and proprietary
information includes any and all methods, inventions, improvements or
discoveries, whether or not patentable or copyrightable, and any other
information of a similar nature disclosed to the directors, officers or
employees of the Company or otherwise made known to us as a consequence of or
through employment or association with the Company (including information
originated by the director, officer or employee). This can include, but is not
limited to, information regarding the Company's business, products, processes,
and services. It also can include information relating to research, development,
inventions, trade secrets, intellectual property of any type or description,
data, business plans, marketing strategies, engineering, contract negotiations,
contents of the Company Intranet; and, business methods or practices.

     The following are examples of information that is not considered
confidential:

     - Information that is in the public domain to the extent such information
       is readily available;

                                       E-6


     - Information that becomes generally known to the public other than by
       disclosure by the Company or a director, officer or employee; or

     - Information you receive from a party, which is under no legal obligation
       of confidentiality with the Company with respect to such information.

     We have exclusive property rights to all confidential and proprietary
information regarding Anadarko or our business associates. The unauthorized
disclosure of this information could destroy its value to the Company and give
others an unfair advantage. You are responsible for safeguarding Company
information and complying with established security controls and procedures. All
documents, records, notebooks, notes, memoranda and similar repositories of
information containing information of a secret, proprietary, confidential or
generally undisclosed nature relating to the Company or our operations and
activities made or compiled by the director, officer or employee or made
available to you prior to or during the term of your association with the
Company, including any copies thereof, unless otherwise agreed to in writing,
belong to the Company and shall be held by you in trust solely for the benefit
of the Company, and shall be delivered to the Company by you on the termination
of your association with us or at any other time we request.

                             CONFLICTS OF INTEREST

     Conflicts of interest can arise in virtually every area of our operations.
A "conflict of interest" exists whenever an individual's private interests
interfere or conflict in any way (or even appear to interfere or conflict) with
the interests of the Company. We must strive to avoid conflicts of interest. We
must each make decisions solely in the best interest of the Company. Any
business, financial or other relationship with suppliers, customers or
competitors that might impair or appear to impair the exercise of our judgment
solely for the benefit of the Company is prohibited.

     Here are some examples of conflicts of interest:

     Family Members.  Actions of family members may create a conflict of
interest. For example, gifts to family members by a supplier of the Company are
considered gifts to you and must be reported. Doing business for the Company
with organizations where your family members are employed or which are partially
or fully owned by your family members or close friends may create a conflict or
the appearance of a conflict of interest. For purposes of the Code "family

                        DISCLOSURE POLICIES AND CONTROLS

     The continuing excellence of the Company's reputation is dependent upon our
full and complete disclosure of important information about the Company that is
used in the securities marketplace. Our financial and non-financial disclosures
and filings with the SEC must be transparent, accurate and timely. Proper
reporting of reliable, truthful and accurate information is a complex process
involving cooperation between many departments and disciplines. We must all work
together to insure that reliable, truthful and accurate information is disclosed
to the public.

     The Company shall disclose to the SEC, current security holders and the
investing public information that is required, and any additional information
that may be necessary to ensure the required disclosures are not misleading or
inaccurate. The Company requires you to participate in the disclosure process,
which is overseen by the Disclosure Committee and the CEO and CFO. The
disclosure process is designed to record, process, summarize and report material
information as required by all applicable laws, rules and regulations.
Participation in the disclosure process is a requirement of a public company,
and full cooperation and participation by members of the Disclosure Committee,
CEO, CFO and, upon request, other employees in the disclosure process is a
requirement of this Code.

     Officers and employees must fully comply with their disclosure
responsibilities in an accurate and timely manner or be subject to discipline of
up to and including termination of employment.

                         ENVIRONMENT, HEALTH AND SAFETY

     Anadarko is committed to managing and operating our worldwide assets in a

procedures on the Anadarko Intranet.

                            FAIR DEALING WITH OTHERS

through manipulation, concealment, abuse of privileged information,
misrepresentation of material facts or any other unfair-dealing practice.

     Any reports or information provided, on our behalf, to federal, state,
local or foreign governments should be true, complete and accurate. Any
omission, misstatement or lack of attention to detail could result in a
violation of the reporting laws, rules and regulations.

                         FOREIGN CORRUPT PRACTICES ACT

     The United States Foreign Corrupt Practices Act prohibits giving anything
of value, directly or indirectly, to foreign government officials or foreign
political candidates in order to obtain, retain or direct business. Accordingly,
corporate funds, property or anything of value may not be, directly or
indirectly, offered or given by you or an agent acting on our behalf, to a
foreign official, foreign political party or official thereof or any candidate

decision of such foreign person or inducing such person to use his influence or
in order to assist in obtaining or retaining business for, or directing business
to, any person.

value to any foreign person if it is known or there is a reason to know that all
or part of such payment will be used for the above-

                                       E-9

matter, machines, manufactures, processes, improvements, data, computer

appropriate patent, copyright, or trademark protection for such intellectual
property.

     Works of authorship including literary works such as books, articles, and
computer programs; musical works, including any accompanying words; dramatic
works, including any accompanying music; pantomimes and choreographic works;
pictorial, graphic, and sculptural works; motion pictures and other audiovisual

to bear a copyright notice in order to be protected and without the copyright
owner's permission, no one may make copies of the work, create derivative works,
distribute the work, perform the work publicly, or display the work publicly.

     We have agreements in place, which grant employees permission to make use

                     INVESTOR RELATIONS AND PUBLIC AFFAIRS

     It is very important that the information disseminated about the Company be
both accurate and consistent. For this reason, the Investor Relations department
and the Public Affairs department are responsible for the Company's internal and
external communications. The Investor Relations department is responsible for
public communications with stockholders, analysts and other interested members
of the financial community. The Public Affairs department is responsible for our
marketing and advertising activities and communication with employees, the
media, local communities and government officials. The Public Affairs department
serves as the spokesperson in both routine and crisis situations. In some cases
where information about a non-routine incident should be made available to the
media before someone from the Public Affairs department has arrived, field
personnel who have been trained in crisis response are authorized to speak for
us until someone from the Public Affairs department is available to handle media
inquiries.

                         NON-RETALIATION FOR REPORTING

     In no event will we take or threaten any action against you as a reprisal
or retaliation for making a complaint or disclosing or reporting information in
good faith. However, if a reporting individual was involved in improper activity
the individual may be appropriately disciplined even if he or she was the one
who disclosed the matter to the Company. In these circumstances, we may consider
the conduct of the

                                       E-11


reporting individual in promptly reporting the information as a mitigating
factor in any disciplinary decision.

     We will not allow retaliation against an employee for reporting a possible
violation of this Code in good faith. Retaliation for reporting a federal
offense is illegal under federal law and prohibited under this Code. Retaliation
for reporting any violation of a law, rule or regulation or a provision of this
Code is prohibited. Retaliation will result in discipline up to and including
termination of employment and may also result in criminal prosecution.

                      PATENTS, COPYRIGHTS, AND TRADEMARKS

     See INTELLECTUAL PROPERTY.

                            POLITICAL CONTRIBUTIONS

     You shall refrain from making any use of Company, personal or other funds
or resources on behalf of the Company for political or other purposes which are
improper or prohibited by the applicable federal, state, local or foreign laws,
rules or regulations. Company contributions or expenditures in connection with
election campaigns will be permitted where allowed by federal, state, local or
foreign election laws, rules and regulations.

     You are encouraged to participate actively in the political process. We
believe that individual participation is a continuing responsibility of those
who live in a free state.

                             PROHIBITED SUBSTANCES

     We have policies prohibiting the use of alcohol, illegal drugs or other
prohibited items, including legal drugs which affect the ability to perform
one's work duties, while on Company premises. We also prohibit the possession or
use of alcoholic beverages, firearms, weapons or explosives on our property
unless authorized by an Executive Officer of the Company. The Company also
prohibits you from reporting to work while under the influence of alcohol or
illegal drugs. We also perform pre-employment and random drug testing on certain
employees. For the procedures on prohibited substances you should see the

                                RECORD RETENTION

     We have detailed document retention policies to systematically establish
retention periods for records created or received in the normal course of
business. A record is information, regardless of physical format, which has been
created or received in the transaction of the Company's business. Physical
format of a record includes hard copy, electronic, magnetic tape, disk, audio,
video, optical image, etc. Each corporate department and division office is
responsible for the maintenance, retrieval, transfer, and destruction of its
records in accordance with the established filing procedures, records retention
schedules and procedures.

     The alteration, destruction or falsification of corporate documents or
records may constitute a criminal act. Destruction or alteration of documents
with the intent to obstruct a pending or anticipated official government
proceeding is a criminal act and could result in large fines and a prison
sentence of up to 20 years. Document destruction or falsification in other
contexts can result in a violation of the federal securities laws or the
obstruction of justice laws.

     Before any destruction of any documents or records, you must consult the
procedures posted on the Anadarko Intranet. You are required to review, follow
and abide by the terms of this policy and related procedures. If the policy or
procedure is not clear, questions arise, or there is a pending or anticipated
official proceeding, then the General Counsel must approve any document
destruction.

              RELATIONS AMONG EMPLOYEES: RESPECT AND CONTRIBUTION

     We function as a team. Your success as part of this team depends on your
contribution and ability to inspire the trust and confidence of your coworkers
and supervisors. Respect for the rights and dignity of others and a dedication
to the good of our Company are essential.

     A cornerstone of Anadarko's success is the teamwork of its directors,
officers and employees. We must each respect the rights of others while working
as a team to fulfill our objectives. To best function as part of a team, you
must be trustworthy and dedicated to high standards of performance. The
relationships between business groups also require teamwork.

     To facilitate respect and contribution among employees, we have implemented
the following employment policies:

     - To hire, pay and assign work on the basis of qualifications and
       performance.

     - Not to discriminate on the basis of race, religion, ethnicity, national
       origin, color, gender, age, citizenship, veteran's status, marital status
       or disability.

     - To attract and retain a highly talented workforce.

     - To encourage skill growth through training and education and promotional
       opportunities.

     - To encourage an open discussion between all levels of employees and to
       provide an opportunity for feedback from the top to the bottom and from
       the bottom to the top.

     - To prohibit any sexual, physical, verbal or any other kind of harassment
       by others while an employee is on the job.

     - To make the safety and security of our employees while at Company
       facilities a priority.

     - To recognize and reward additional efforts that go beyond our
       expectations.

     - To respect all workers' rights to dignity and personal privacy by not
       disclosing employee information, including protected health information,
       unnecessarily.

                          REPORTING OF CODE VIOLATIONS

     You should be alert and sensitive to situations that could result in
actions that might violate federal, state, or local laws or the standards of
conduct set forth in this Code. If you believe your own conduct or that of a
fellow employee may have violated any such laws or this Code, you have an
obligation to report the matter.

     Generally, you should raise such matters first with an immediate
supervisor. However, if you are not comfortable bringing the matter up with your
immediate supervisor, or do not believe the supervisor has dealt with the matter
properly, then you should raise the matter with the Vice President in charge of
your division or, if a law, rule or regulation is in question, then consult with
the General Counsel. The most important point is that possible violations should
be reported and we support all means of reporting them.

     Directors and officers should report any potential violations of this Code
to the Chief Governance Officer or the Nominating and Corporate Governance
Committee of the Board of Directors.

                                    WAIVERS

     There shall be no waiver of any part of this Code for any director or
officer except by a vote of the Board of Directors or a designated board
committee that will ascertain whether a waiver is appropriate under all the
circumstances. In case a waiver of this Code is granted to a director or
officer, the notice of such waiver shall be posted on our website within five
days of the Board of Director's vote or shall be otherwise disclosed as required
by applicable law or New York Stock Exchange rule. Notices posted on our website
shall remain there for a period of 12 months and shall be retained in our files
as required by law.
                                       E-13


     A waiver for a specific event arising under the "Conflicts of Interest"
section of this Code may be granted to an employee that is not a director or
officer on the approval of two of the following officers: the Vice President in
charge of the division or department for which the employee works; the General
Counsel; and, the Chief Governance Officer. No other waivers of this Code are
permitted.

                                   CONCLUSION

     This Code is an attempt to point all of us at Anadarko in the right
direction, but no document can achieve the level of principled compliance that
we are seeking. In reality, each of us must strive every day to maintain our
awareness of these issues and to comply with the Code's principles to the best
of our abilities. We must always ask:
         Does it feel right?
         Is this action ethical in every way?
         Is this action in compliance with the law?
         Could my actions create an appearance of impropriety?
         Am I trying to fool anyone, including myself, about the propriety of
         this action?

     We cannot expect perfection, but we do expect good faith. If you act in bad
faith or fail to report illegal or unethical behavior, then you will be subject
to disciplinary procedures. We hope that you agree that the best course of
action is to be honest, forthright and loyal at all times.

                                                                      APPENDIX F

                         ANADARKO PETROLEUM CORPORATION

    CODE OF ETHICS FOR THE CHIEF EXECUTIVE OFFICER, CHIEF FINANCIAL OFFICER
                          AND CHIEF ACCOUNTING OFFICER

     In my role as Chief Executive Officer ("CEO"), Chief Financial Officer
("CFO") or Chief Accounting Officer ("CAO") of Anadarko Petroleum Corporation
(the "Company"), I have adhered to and advocated to the best of my knowledge and
ability the following principles and responsibilities governing professional
conduct and ethics:

          1. Act with honesty and integrity, avoiding actual or apparent
             conflicts of interest in personal and professional relationships. A
             "conflict of interest" exists when an individual's private
             interests interfere or conflict in any way (or even appear to
             interfere or conflict) with the interests of the Company.

          2. Provide constituents with information that is accurate, complete,
             objective, relevant, timely and understandable. If I am the CEO or
             CFO I shall review the annual and quarterly reports before
             certifying and filing them with the SEC.

          3. Comply with all applicable laws, rules and regulations of federal,
             state and local governments, and other appropriate private and
             public regulatory agencies.

          4. Act in good faith, responsibly, with due care, competence and
             diligence, without misrepresenting material facts or allowing my
             independent judgement to be subordinated.

          5. Respect the confidentiality of information acquired in the course
             of business except when authorized or otherwise legally obligated
             to disclose the information. I acknowledge that confidential
             information acquired in the course of business is not to be used
             for personal advantage.

          6. Proactively promote ethical behavior among employees at the Company
             and as a responsible partner with industry peers and associates.

          7. Maintain control over and responsibly manage all assets and
             resources employed or entrusted to me by Anadarko.

          8. Report illegal or unethical conduct by any director, officer or
             employee that has occurred, is occurring or may occur, including
             any potential violations of this Code or the Anadarko Code of
             Business Conduct and Ethics. Such report shall be made to the Chief
             Governance Officer or the Nominating and Corporate Governance
             Committee of the Board of Directors and shall include conduct of a
             financial or non-financial nature.

          9. Comply with this Code and the Anadarko Code of Business Conduct and
             Ethics. I understand that if I violate any part of this Code, I
             will be subject to disciplinary action.

     I understand that this Code is subject to all applicable laws, rules and
regulations. This Code incorporates by reference the Anadarko Code of Business
Conduct and Ethics that applies to all directors, officers and employees.

     I understand that if there is a conflict between this Code and a Company
policy or procedure, the Anadarko Code of Business Conduct and Ethics, or any
applicable law, rule or regulation, then I must consult with the Legal
Department for guidance.

                                       F-1


     I understand that there shall be no waiver of, modification of, or change
to any part of this Code except by a vote of the Board of Directors or a
designated Board committee. In the event that a waiver of, modification of, or a
change to this Code is granted, then the notice of the waiver, modification
and/or change shall be posted on the Company's website within five business days
of the Board of Director's or designated Board committee's vote or shall be
disclosed otherwise as required by applicable law or NYSE or SEC rules. Notices
posted on the Company website shall remain there for a period of 12 months and
shall be retained in the Company's files as required by law.
