               THE APPROVED UK SUB-PLAN OF THE ANADARKO PETROLEUM

  APPROVED BY THE INLAND REVENUE ON 14 OCTOBER 2003 UNDER REFERENCE X22436/GRP

This sub-plan together with the Anadarko Petroleum Corporation 1999 Stock
Incentive Plan (the "1999 Plan") to the extent that it applies to Stock Options
shall constitute the rules of the Approved UK Sub-Plan ("the Sub-Plan")
established by the Committee and approved by the United Kingdom Inland Revenue
under Schedule 4 to the Income Tax (Earnings and Pensions) Act 2003. Subject to
the succeeding paragraphs of this Sub-Plan, the terms and conditions of the 1999
Plan are incorporated herein. In the event of any conflict between the terms of
the 1999 Plan and the Sub-Plan, the terms of the Sub-Plan will take precedence
insofar as Stock Options granted to UK Eligible Employees are concerned.

The Sub-Plan is an addendum to the Plan and provides for a modification of a
number of the terms of the Plan insofar as they relate to Stock Options which
are to be granted under and with the benefit of UK Inland Revenue approved
status. The terms of the Sub-Plan, including in particular the material terms of
Stock Options which may be granted under the Sub-Plan, the class of persons who
may receive Stock Options under the Sub-Plan, the terms of the Sub-Plan and the
method of determining the Exercise Price of Stock Options under the Sub-Plan,
are in all material respects the same as the equivalent provisions in the Plan.
The maximum number of Shares which may can be made available under the Plan
includes Shares over which Stock Options under the Sun-Plan may be granted. Any
terms of the Plan which have been modified in the Sub-Plan have been so modified
in order to obtain or facilitate approval of the Sub-Plan as so modified by the
UK Inland Revenue.

       accordance with Section 11.

3      PLAN ADMINISTRATION

3.1    With the exception of Sub-Sections b, c, e, f and h, Section 3 shall
       apply to the Sub-Plan save that any terms and conditions imposed by the
       Committee shall be objective, set out in full in the option agreement,
       such that rights to exercise a Stock Option after the attainment or
       fulfilment of such objective conditions shall not be dependent upon the
       discretion of any person, and not capable of amendment or waiver unless
       events happen which cause the Committee to reasonably consider that the
       condition has ceased to be appropriate, in which case any adjusted
       conditions shall be a fairer measure of the terms and conditions and be
       no more difficult to satisfy than those imposed at the Date of Grant.

3.2    Sub-Section 3(d) shall apply provided that no Stock Option may be
       exercised more than ten years from the Date of Grant.

       Date.

5      SHARES SUBJECT TO THE PLAN

       treasury to satisfy the exercise in full of all Stock Options for the
       time being remaining capable of being exercised.

(b)    Any Stock Option granted to any Eligible Employee shall be limited and
       take effect so that immediately following such grant he would hold
       Subsisting Options over Shares with an aggregate Fair Market Value not
       exceeding Pound Sterling30,000 or such other limit as may then be
       specified in paragraph 6(1) of Schedule 4.

(c)    For the purpose of this Rule 5 the Fair Market Value of Shares shall be
       calculated in accordance with paragraph 6(3) of Schedule 4.

       Subsisting Options under this Sub-Plan and options which have been
       granted under any Other Option Plan which have not lapsed, been
       surrendered, renounced or exercised in full.

       Market Value of Shares shall be the amount in United States dollars
       converted into pounds sterling at the highest buying rate shown in the
       day's spread as published in the Financial Times for the relevant date.

(f)    Only Stock Options may be granted under the Sub-Plan and no dividends or
       dividend equivalents shall be payable in respect of Stock Options.

(g)    Shares issued or transferred to a Participant upon an exercise of a Stock
       Option will rank pari passu in all respects with other shares of the same
       class with effect from the date on which the share certificate evidencing
       such Shares is issued (as evidenced by an appropriate entry in the books
       of the Company or of a duly authorised transfer agent of the Company).

6      ADJUSTMENTS AND REORGANISATIONS

6.1    Section 4(d) shall not apply but in the event of any variation of the
       share capital of the Company (within the meaning of paragraph 22(3) of
       Schedule 4 and including, but not limited to, any capitalisation, rights
       issue or open offer or any consolidation, sub-division or reduction of
       capital) the number of Shares subject to any Stock Option and the
       Exercise Price may be adjusted by the Company in such manner as in their
       opinion fair and reasonable provided that:

(a)    at any time the Sub-Plan remains approved by the Inland Revenue no
       adjustment shall take effect without the prior approval of the Board of
       the Inland Revenue; and

(b)    at any time the Sub-Plan remains approved by the Inland Revenue following
       the adjustment the Shares continue to satisfy the requirements of
       paragraphs 16 to 20 inclusive of Schedule 4.

6.2    Such variation under Rule 6.1 shall be deemed to be effective, once
       Inland Revenue approval has been given, from the record date at which the
       respective variation applied to other shares of the same class as the
       Shares.

6.3    If an adjustment is made pursuant to this Rule 6 with the intention that
       the Sub-Plan shall cease to be approved by the Inland Revenue, the
       Company shall immediately notify the Inland Revenue.

6.4    Sub-Section 7(c) shall be disapplied for the purposes of the Sub-Plan.

7      FAIR MARKET VALUE

       No Stock Option may be granted under the Sub-Plan at less than the Fair
       Market Value of a Share on the Date of Grant and Sub Section 6(a)(i)
       shall be amended accordingly.

9      EXERCISE

       his employer or former employer being the Company or any subsidiary
       thereof is liable to make a payment to the appropriate authorities on
       account of that liability no Stock Option shall be exercisable unless,
       prior to the proposed exercise, the Participant shall either

(a)    grant to the Company the irrevocable authority, as agent of the
       Participant and on his behalf, to sell or procure the sale of sufficient
       of the Shares subject to the Stock Option so that the net proceeds
       payable to the Company are so far as possible equal to but not less than
       the amount payable to the appropriate authorities so that the Company may
       then pay over the proceeds from the sale to the Participant's employing
       company and the Participant's employing company shall pay any income tax
       and/or other relevant amount due on the exercise of the Stock Option and
       account to the Participant for any balance;

       by the Participant's employing company that the arrangements are
       satisfactory; or

(c)    pay to the Company or, as appropriate, the Participant's employing
       company in pounds sterling (whether by cheque or banker's draft) the
       amount necessary to satisfy such liabilities.

14     CHANGE OF CONTROL

14.1   Subject to Rule 14.2, Section 8 shall apply.

14.2   Subject to Rule 14.3, if any company obtains Control of the Company as a
       result of making:

(a)    a general offer to acquire the whole of the issued share capital of the
       Company which is made on a condition such that if it is satisfied the
       company making the offer will have Control of the Company; or

(b)    a general offer to acquire all of the shares of the Company which are of
       the same class as the Shares

       then, provided that the circumstances of the change in Control are within
       paragraph 26(2)(a) such that a New Option can be offered, the Participant
       may, within the appropriate period and if the Acquiring Company so
       agrees, release any Stock Option he holds which has been granted under
       the Sub-Plan in consideration for the grant of a New Option which is
       equivalent to the Stock Option but relates to shares in a different
       company (whether the

                                       8
<PAGE>
       acquiring company itself or some other company falling within paragraphs
       16(a), 16(b) or 16(c) of Schedule 4.

14.3   For the purposes of Rule 14.2:

(a)    an "appropriate period" shall be the period of six months beginning with
       the time when the person making the offer has obtained Control of the
       Company and any condition subject to which the offer is made is
       satisfied; and

(b)    a New Option shall not be regarded as "equivalent" to the old Stock
       Option unless the requirements of paragraph 27(4) of Schedule 4 are met.

14.4   If any person obtains Control of the Company in the circumstances
       described in Rule 14.2(a) and (b) and a Participant is not offered a New
       Option, the Participant shall have the right to exercise his Stock Option
       in accordance with Section 8.

14.5   Sub-Sections 8(a)(ii), 8(a)(iii) and 8(b) shall be disapplied for the
       purposes of the Sub-Plan.

15     GOVERNING LAW

       Sub-Section 9(f) shall continue to apply save that English legislative
       provisions shall be construed according to the Laws of England.

16     EMPLOYMENT RIGHTS

       The rights and obligations of any individual under the terms of his
       office or employment with any Group Company shall not be affected by his
       participation in the Sub-Plan or any right which he may have to
       participate therein, and an individual who participates therein shall
       waive any and all rights to compensation or damages in consequence of the
       termination of his office or employment (whether lawfully or unlawfully)
       for any reason whatsoever insofar as those rights arise or may arise from
       his ceasing to have rights under or be entitled to exercise any Stock
       Option under the Sub-Plan as a result of such termination or in
       consequence of any loss of income tax relief under sections 524 or 525 of
       the Income Tax (Earnings and Pensions) Act 2003 as a result of the
       Sub-Plan and/or his Stock Options losing approval under that act.

17     DATA PROTECTION

17.1   Where in any Rule there is a requirement for any notice or document to be
       sent to any person by any other person, it shall be considered sent if an
       electronic transmission of the relevant information is sent in a form
       previously determined as being acceptable to the Committee. For the
       avoidance of doubt the Committee may dispense with the requirement to
       tender an option certificate on the exercise of the relevant Stock Option
       where they authorise any system permitting the exercise of Stock Options
       by means of electronic notification. A requirement under these Rules for
       the making of any payment may be discharged by the electronic
       transmission of an authorisation to charge any account or credit card.

17.2   It is a condition of participation in this Sub-Plan that a Participant
       agree to the holding of information about him by the Company and that he
       authorise the Company and its agents and advisers to use such information
       according to these Rules for the purposes of this Sub-Plan. It is a
       further condition of participation in this Sub-Plan that each Participant
       agrees

                                       9
<PAGE>

       that data concerning his participation may be processed by agents of the
       Company wherever located and where necessary transmitted outside of the
       United Kingdom.

18     MISCELLANEOUS

18.1   For the avoidance of doubt, Awards of Incentive Stock Options,
       Performance Awards, Restricted Stock and Stock Appreciation Rights may
       not be made under this Sub-Plan.

18.2   For the avoidance of doubt, in the event that the Sub-Plan and/or Stock
       Options awarded under it lose their approved status under Schedule 4 to
       the Income Tax (Earnings and Pensions) Act 2003 any subsisting Stock
       Options shall continue to subsist as if they had been granted under the
       provisions of the main Plan.
