Exhibit 10.28

                    1998 KEY EMPLOYEE STOCK PERFORMANCE PLAN
                                OF CONOCOPHILLIPS

               (AS AMENDED AND RESTATED EFFECTIVE AUGUST 30, 2002)

                                    RECITALS

            Conoco Inc. ("Conoco") established the 1998 Key Employee Stock
Performance Plan of Conoco Inc. (the "Plan") effective October 16, 1998.
Paragraph 5 specifies the number of shares of Common Stock with respect to which
Awards may be granted under the Plan. Paragraph 13 reserves to the Board the
right to amend the Plan. Paragraph 15 provides that in the event of certain
transactions, including a reorganization, the Board is authorized to (a) issue
or assume Awards by means of substitution of new Awards, as appropriate, for
previously issued Awards or an assumption of previously issued Awards as part of
such adjustment or (b) cancel Awards that are Options or SARs and give
Participants who are holders of such Awards notice and opportunity to exercise
for 30 days prior to such cancellation.

            Effective October 8, 2001, Conoco reclassified its Class A Common
Stock and Class B Common Stock into a single class of new common stock ("Common
Stock") by merging Conoco Delaware I, Inc., a wholly owned subsidiary of Conoco
("Merger Sub"), with and into Conoco (the "Merger"), pursuant to an Agreement
and Plan of Merger, dated as of July 17, 2001, between Conoco and Merger Sub. In
connection with the Merger and pursuant to their authority under Paragraph 13,
the Board authorized the amendment and restatement of the Plan to provide for
the issuance of Awards with respect to the new class of Common Stock, effective
October 8, 2001 (the effective time of the Merger). In addition, in connection
with the Merger and effective October 8, 2001, pursuant to its authority under
Paragraph 15, the Board substituted a new Award for each previously issued
outstanding Award. The new Award applied to a number of shares of Common Stock
equal to the total number of shares of Conoco Class A Common Stock and Class B
Common Stock for which the previously issued outstanding Award had not been
exercised, and provides for the same exercise price and the same other terms and
conditions as those applicable under the previously issued outstanding Award.

            On September 21, 2001, the stockholders of Conoco approved a Plan
amendment to increase the number shares of Common Stock available for Awards
under the Plan, which increase was included in the October 8, 2001 amendment and
restatement of the Plan.

            On October 30, 2001, the Board of Directors of Conoco approved
certain stock award and Plan amendment limitations to the Plan.

            Effective November 18, 2001, Conoco entered into the Agreement and
Plan of Merger by and among Phillips Petroleum Company, Corvette Porsche Corp.,
Porsche Merger Corp., Corvette Merger Corp. and Conoco (the "Phillips Merger
Agreement"), which provides for a series of transactions including the formation
of ConocoPhillips, a Delaware corporation, and the merger of Conoco into and
with a subsidiary of ConocoPhillips (collectively, the "Phillips Merger"). In
connection with and effective upon the closing of the Phillips Merger, the Board
of Directors of Conoco approved the amendment and restatement of the Plan to
reflect the

transfer of sponsorship to ConocoPhillips, the renaming of the Plan as the "1998
Key Employee Stock Performance Plan of ConocoPhillips," and to make certain
changes related thereto.

or receive payments determined by reference to such Common Stock.

      2. Objectives. The purpose of this Amended and Restated 1998 Key Employee
Stock Performance Plan of ConocoPhillips is to further the interests of the
Company, its Subsidiaries and its shareholders by providing incentives in the
form of Awards to Employees and to provide for issuance of Awards in connection
with the "Option Program" under which certain existing DuPont awards were
canceled at the election of the holder. Such Awards will give Participants in
the Plan an interest in the Company parallel to that of the shareholders, thus
enhancing the proprietary and personal interest of such Participants in the

      4. Eligibility. All Employees are eligible for the grant of Awards under
this Plan.

      5. Common Stock Available for Awards.

            (a) Subject to the provisions of paragraph 15 hereof, no Award shall
      be granted if it shall result in the aggregate number of shares of Common
      Stock issued under the Plan plus the number of shares of Common Stock
      covered by or subject to Awards then outstanding (after giving effect to
      the grant of the Award in question) to exceed 17,576,459. No more than
      5,612,400 shares of Common Stock shall be available for Incentive Stock

      unexercised, are settled in cash in lieu of Common Stock or in a manner
      such that all or some of the shares covered by an Award are not issued to

      hereunder. The Committee may from time to time adopt and observe such
      procedures concerning the counting of shares against the Plan maximum as
      it may deem appropriate. The Board and the appropriate officers of the
      Company shall from time to time take whatever actions are necessary to
      file any required documents with

      pursuant to Awards.

            (b) Option Program Awards and awards assumed under the Plan or
      issued as substitute Awards, each pursuant to paragraph 15(b) of the Plan,
      (i) are not subject to the limitations in paragraph 8(b) and (ii) do not
      count against the limitations on Common Stock available for Awards set
      forth in paragraph 5(a).

      6. Administration.

            (a) The Plan shall be administered by the Committee.

            (b) The Committee shall have full and exclusive power and authority
      to administer this Plan and to take all actions that are specifically
      contemplated hereby or are necessary or appropriate in connection with the
      administration hereof. The Committee shall also have full and exclusive
      power to interpret this Plan and to adopt such rules, regulations and
      guidelines for carrying out this Plan as it may deem necessary or proper,
      all of which powers shall be exercised in the best interests of the
      Company and in keeping with the objectives of this Plan. The Committee
      may, in its discretion, provide for the extension of the exercisability of
      an Award, accelerate the vesting or exercisability of an Award, eliminate
      or make less restrictive any restrictions applicable to an Award, waive
      any restriction or other provision of this Plan or otherwise amend or
      modify an Award in any manner that is either (i) not adverse to the
      Participant to whom such Award was granted or (ii) consented to by such
      Participant. The Committee may grant an Award to an Employee who it
      expects to become an employee of the Company or any of its Subsidiaries
      within the following six months, with such Award being subject to the
      individual's actually becoming an employee within such time period, and
      subject to such other terms and conditions as may be established by the
      Committee. The Committee may correct any defect or supply any omission or
      reconcile any inconsistency in this Plan or in any Award in the manner and
      to the extent the Committee deems necessary or desirable to further the
      Plan purposes. Any decision of the Committee in the interpretation and
      administration of this Plan shall lie within its sole and absolute
      discretion and shall be final, conclusive and binding on all parties
      concerned.

            (c) No member of the Committee or officer of the Company to whom the
      Committee has delegated authority in accordance with the provisions of
      paragraph 7 of this Plan shall be liable for anything done or omitted to
      be done by him or her, by any member of the Committee or by any officer of
      the Company in connection with the performance of any duties under this
      Plan, except for his or her own willful misconduct or as expressly
      provided by statute.

      7. Delegation of Authority. The Committee may delegate to the Chief
Executive Officer and to other senior officers of the Company its duties under
this Plan pursuant to such conditions or limitations as the Committee may
establish. The Committee may engage or authorize the engagement of a third party
administrator to carry out administrative functions under the Plan.


                                       5

      8. Awards.

            (a) The Committee shall determine the type or types of Awards to be
      made under this Plan and shall designate from time to time the Employees
      who are to be the recipients of Awards. Each Award shall be embodied in an
      Award Agreement, which shall contain such terms, conditions and
      limitations as shall be determined by the Committee in its sole discretion
      and, if required by the Committee, shall be signed by the Participant to
      whom the Award is granted and by an Authorized Officer for and on behalf
      of the Company. Awards may consist of those listed in this paragraph 8(a)
      and may be granted singly, in combination or in tandem. Awards may also be
      granted in combination or in tandem with, in replacement of, or as
      alternatives to, grants or rights under this Plan or any other employee
      plan of the Company or any of its Subsidiaries, including the plan of any
      acquired entity. An Award may provide for the grant or issuance of
      additional, replacement or alternative Awards upon the occurrence of
      specified events, including the exercise of the original Award granted to
      a Participant. All or part of an Award may be subject to conditions
      established by the Committee, which may include, but are not limited to,
      continuous service with the Company and its Subsidiaries, achievement of
      specific business objectives, increases in specified indices, attainment
      of specified growth rates and other comparable measurements of
      performance. Upon the termination of employment by a Participant, any
      unexercised, deferred, unvested or unpaid Awards shall be treated as set
      forth in the applicable Award Agreement.

                  (i) Options. An Award may be in the form of an Option, which
            may be an Incentive Stock Option or a Nonqualified Stock Option. The
            Grant Price of an Option shall be not less than the Fair Market
            Value of the Common Stock subject to such Option on the Grant Date.
            Subject to the foregoing provisions, the terms, conditions and
            limitations applicable to any Options awarded to Employees pursuant
            to this Plan, including the Grant Price, the term of the Options and
            the date or dates upon which they become exercisable, shall be
            determined by the Committee.

                  (ii) Stock Appreciation Rights. An Award may be in the form of
            an SAR. The terms, conditions and limitations applicable to any SARs
            awarded to Employees pursuant to this Plan, including the Grant
            Price, the term of any SARs and the date or dates upon which they
            become exercisable, shall be determined by the Committee.

            (b) Notwithstanding anything to the contrary contained in this Plan
      excluding paragraph 5(b), no Participant may be granted, during any
      calendar year, Awards that are exercisable for more than 93,540 shares of
      Common Stock.

            (c) Stock Awards, other than those awards which are subject to
      specific grant limitations under the Plan, shall be in lieu of, and have a
      Fair Market Value on the Grant Date equal to, other compensation that the
      Company would otherwise have awarded to the Participant.


                                       6

      9. Change of Control. Notwithstanding the provisions of paragraph 8
hereof, unless otherwise expressly provided in the applicable Award Agreement,
in the event of a Change of Control during a Participant's employment with the
Company or one of its Subsidiaries, (i) each Award granted under this Plan to
the Participant shall be become immediately vested and fully exercisable
(regardless of the otherwise applicable vesting or exercise schedules or
performance goals provided for under the Award Agreement) and (ii) if the Award
is an Option or SAR, shall remain exercisable until the expiration of the term
of the Award or, if the Participant should die before the expiration of the term
of the Award, until the earlier of (a) the expiration of the term of the Award
or (b) two (2) years following the date of the Participant's death.

      10. Payment of Awards.

            (a) General. Payment made to a Participant pursuant to an Award may
      be made in the form of cash or Common Stock, or a combination thereof, and
      may include such restrictions as the Committee shall determine, including,
      in the case of Common Stock, restrictions on transfer and forfeiture
      provisions.

            (b) Deferral. With the approval of the Committee, amounts payable in
      respect of Awards may be deferred and paid either in the form of
      installments or as a lump-sum payment. The Committee may permit selected
      Participants to elect to defer payments of some or all types of Awards or
      any other compensation otherwise payable by the Company in accordance with
      procedures established by the Committee and may provide that such deferred
      compensation may be payable in shares of Common Stock. Any deferred
      payment pursuant to an Award, whether elected by the Participant or
      specified by the Award Agreement or by the Committee, may be forfeited if
      and to the extent that the Award Agreement so provides.

            (c) Substitution of Awards. At the discretion of the Committee, a
      Participant may be offered an election to substitute an Award for another
      Award or Awards of the same or different type. Subject to Paragraph 15,
      the Grant Price of any Option shall not be decreased, including by means
      of issuance of a substitute Award with a lower Grant Price.

            (d) Cash-out of Awards. At the discretion of the Committee, an Award
      may be settled by a cash payment equal to the difference between the Fair
      Market Value per share of Common Stock on the date of exercise and the
      Grant Price of the Award, multiplied by the number of shares with respect
      to which the Award is exercised.

      11. Option Exercise. The Grant Price shall be paid in full at the time of
exercise in cash or, if permitted by the Committee and elected by the optionee,
the optionee may purchase such shares by means of tendering Common Stock or
surrendering another Award valued at Fair Market Value on the date of exercise,
or any combination thereof. The Committee shall determine acceptable methods for
Participants to tender Common Stock or other Awards. The Committee may provide
for procedures to permit the exercise or purchase of such Awards by use of the
proceeds to be received from the sale of Common Stock issuable pursuant to an
Award. The Committee may adopt additional rules and procedures regarding the
exercise of Options from time to time, provided that such rules and procedures
are not inconsistent with the


                                       7

provisions of this paragraph. An optionee desiring to pay the Grant Price of an
Option by tendering Common Stock using the method of attestation may, subject to
any such conditions and in compliance with any such procedures as the Committee
may adopt, do so by attesting to the ownership of Common Stock of the requisite
value, in which case the Company shall issue or otherwise deliver to the
optionee upon such exercise a number of shares of Common Stock subject to the
Option equal to the result obtained by dividing (a) the excess of the aggregate
Fair Market Value of the shares of Common Stock subject to the Option for which
the Option (or portion thereof) is being exercised over the Grant Price payable
in respect of such exercise by (b) the Fair Market Value per share of Common
Stock subject to the Option, and the optionee may retain the shares of Common
Stock the ownership of which is attested.

      12. Taxes. The Company or its designated third party administrator shall
have the right to deduct applicable taxes from any payment hereunder and
withhold, at the time of delivery of cash or shares of Common Stock under this
Plan, an appropriate amount of cash or number of shares of Common Stock or a
combination thereof for payment of taxes or other amounts required by law or to
take such other action as may be necessary in the opinion of the Company to
satisfy all obligations for withholding of such taxes. The Committee may also
permit withholding to be satisfied by the transfer to the Company of shares of
Common Stock theretofore owned by the holder of the Award with respect to which
withholding is required. If shares of Common Stock are used to satisfy tax
withholding, such shares shall be valued based on the Fair Market Value when the
tax withholding is required to be made. The Committee may provide for loans, on
either a short term or demand basis, from the Company to a Participant to permit
the payment of taxes required by law.

      13. Amendment, Modification, Suspension or Termination of the Plan. The
Board may amend, modify, suspend or terminate this Plan for the purpose of
meeting or addressing any changes in legal requirements or for any other purpose
permitted by law, except that (i) no amendment or alteration that would
adversely affect the rights of any Participant under any Award previously
granted to such Participant shall be made without the consent of such
Participant and (ii) no amendment or alteration shall be effective prior to its
approval by the stockholders of the Company to the extent such approval is
required by applicable legal requirements. In addition, if an amendment would
(i) materially increase the benefits accruing to Participants under this Plan,
(ii) materially increase the aggregate number of securities that may be issued
under this Plan, or (iii) materially modify the requirements as to eligibility
for participation in this Plan, then to the extent required by applicable law,
or deemed necessary by the Committee, such amendment shall be subject to
shareholder approval.

      14. Assignability. Unless otherwise determined by the Committee and
provided in the Award Agreement, no Award or any other benefit under this Plan
shall be assignable or otherwise transferable except by will, beneficiary
designation or the laws of descent and distribution. In the event that a
beneficiary designation conflicts with an assignment by will, the beneficiary
designation will prevail. The Committee may prescribe and include in applicable
Award Agreements other restrictions on transfer. Any attempted assignment of an
Award or any other benefit under this Plan in violation of this paragraph 14
shall be null and void.


                                       8

      15. Adjustments.

            (a) The existence of outstanding Awards shall not affect in any
      manner the right or power of the Company or its stockholders to make or
      authorize any or all adjustments, recapitalizations, reorganizations or
      other changes in the capital stock of the Company or its business or any
      merger or consolidation of the Company, or any issue of bonds, debentures,
      preferred or prior preference stock (whether or not such issue is prior
      to, on a parity with or junior to the existing Common Stock) or the
      dissolution or liquidation of the Company, or any sale or transfer of all
      or any part of its assets or business, or any other corporate act or
      proceeding of any kind, whether or not of a character similar to that of
      the acts or proceedings enumerated above.

            (b) In the event of any subdivision or consolidation of outstanding
      shares of Common Stock, declaration of a dividend payable in shares of
      Common Stock or other stock split, then (i) the number of shares of Common
      Stock reserved under this Plan, (ii) the number of shares of Common Stock
      covered by outstanding Awards, (iii) the Grant Price in respect of such
      Awards, (iv) the appropriate Fair Market Value and other price
      determinations for such Awards, and (v) the Award limitations shall each
      be proportionately adjusted by the Board as appropriate to reflect such
      transaction. In the event of any other recapitalization or capital
      reorganization of the Company, any consolidation or merger of the Company
      with another corporation or entity, the adoption by the Company of any
      plan of exchange affecting any Common Stock or any distribution to holders
      of Common Stock of securities or property (other than normal cash
      dividends or dividends payable in Common Stock), the Board shall make
      appropriate adjustments to (i) the number of shares of Common Stock
      covered by Awards, (ii) the Grant Price in respect of such Awards, (iii)
      the appropriate Fair Market Value and other price determinations for such
      Awards, and (iv) the Award limitations to reflect such transaction;
      provided that such adjustments shall only be such as are necessary to
      maintain the proportionate interest of the holders of the Awards and
      preserve, without increasing, the value of such Awards. In the event of a
      corporate merger, consolidation, acquisition of property or stock,
      separation, reorganization or liquidation, the Board shall be authorized
      (x) to assume under the Plan previously issued compensatory awards, or to
      substitute new Awards for previously issued compensatory awards, including
      Awards as part of such adjustment or (y) to cancel Awards that are Options
      or SARs and give the Participants who are the holders of such Awards
      notice and opportunity to exercise for 30 days prior to such cancellation.

      16. Restrictions. No Common Stock or other form of payment shall be issued
with respect to any Award unless the Company shall be satisfied based on the
advice of its counsel that such issuance will be in compliance with applicable
federal and state securities laws. Certificates evidencing shares of Common

      pursuant to Rule 13d-3 of the General Rules and Regulations under the
      Exchange Act, as in effect on August 30, 2002) such securities or

      writing); provided, however, that a Person shall not be deemed the
      "Beneficial Owner" of, or to "beneficially own," any security under this
      subsection (a) as a result of an agreement, arrangement or understanding
      to vote such security if such agreement, arrangement or understanding: (i)
      arises solely from a revocable proxy or consent given in response to a
      public (i.e., not including a solicitation exempted by Rule 14a-2(b)(2) of

relating to corporate action (including, without limitation, a demand for a
stockholder list, to call a stockholder meeting or to inspect corporate books
and records) or otherwise giving an authorization (within the meaning of Section
14(a) of the Exchange Act) in respect of such security.
