As soon as practicable after the beginning of the year the Committee shall
determine the Performance Measures for the Plan Year and shall advise
Participants of the Performance Measures. The Performance Measures may include

SECTION 5. DETERMINATION OF AWARDS

Following the completion of the Plan Year, the Committee will review the
Company's performance with respect to the Performance Measures, and in its sole

Employees. No Awards will be granted if the threshold Performance Measure

SECTION 6. PAYMENT OF AWARDS

      (a)   Each Award may be made at the discretion of the Committee either in
            cash, in Stock, in Restricted Stock, in Stock


                                      -7-
<PAGE>
            Units, or in another form as determined by the Committee and may be
            made partly in one form and partly in one or more other forms. In
            the case of an Award in Stock, Restricted Stock, or Stock Units, the
            number shall be determined by using the Fair Market Value Per share
            of Stock on the date of the Award, provided, however, that no
            Employee whose acquisition of Stock, Restricted Stock, Stock Units
            or other form of Award would be subject to the provisions of Section
            16 of the Exchange Act shall be eligible to receive an Award
            otherwise than in cash, and the Committee shall grant Awards to such
            persons only in cash, unless prior to the grant of any such Award
            all action necessary to qualify such award for the exemption under
            Rule 16b-3 shall have been taken.

      (b)   The payment of any Award shall be subject to such obligations or
            conditions as the Committee may specify in making or recommending
            the Award, but Awards need not be evidenced by Award Agreements.

      (c)   Part or all of a cash Award may be deferred by a Participant under
            the terms of the Key Employee Deferred Compensation Plan of Phillips
            Petroleum Company or any successor plan thereto.


                                      -8-
<PAGE>
      (d)   Any Award payable in Stock or Restricted Stock may, in the
            discretion of the Committee, be paid part or all in cash, on each
            date on which payment in Stock or Restricted Stock would otherwise
            have been made, in an amount equal to the Fair Market Value per
            share of Stock on each such date, multiplied by the number of shares
            of Stock or Restricted Stock which would otherwise have been paid on
            such date.

      (e)   Awards may be granted in Restricted Stock that is issued to a
            Participant and is subject to such terms, conditions and
            restrictions as the Committee deems appropriate, which may include
            restrictions upon the sale, assignment, transfer or other
            disposition of the Restricted Stock and the requirement of
            forfeiture of the Restricted Stock upon termination of employment
            under certain specified conditions. The Committee may provide for
            the lapse of any such term or condition or waive any term or
            condition based on such factors or criteria as the Committee may
            determine. The Participant shall have, with respect to awards of
            Restricted Stock, all of the rights of a shareholder of the Company,
            including the right to vote the Restricted Stock and the rights to
            receive any cash or stock dividend on such Stock.


                                      -9-
<PAGE>
      (f)   Awards may be granted in Stock Units that are subject to such terms
            and conditions as the Committee deems appropriate. The number of
            Stock Units awarded with respect to any Award shall be the number
            determined by using the Fair Market Value per share of Stock on the
            date of the Award. Any Award made in Stock Units may, in the
            discretion or the recommendation of the Committee, be paid in shares
            of Stock on each date on which payment in cash would otherwise be
            made.

      (g)   In lieu of the foregoing forms of payment of Awards, the Committee
            may specify or recommend any other form of payment which it
            determines to be of substantially equivalent economic value to the
            cash value of the Award including, without limitation, forms
            involving payments to a trust or trusts for the benefit of one or
            more Participants.

      (h)   Each payment of an Award that is to be made in cash shall be from
            the general funds of the Company or the Participating Subsidiary
            making the payment.

      (i)   In the event the Participant resigns during the Plan Year or before
            Awards are paid for the Plan Year, no Awards shall be made to that
            Participant, provided, that the


                                      -10-
<PAGE>
            Committee may, in its sole discretion, determine that an Award shall
            be made with respect to the period of time during which the
            Participant was an Employee.

      (j)   In the event the Participant transfers to a non-participating
            subsidiary or otherwise becomes ineligible prior to the end of the
            Plan Year, the Participant may remain a Participant for the purpose
            of all Awards which shall have been made prior to the Participant's
            transfer or prior to the Participant becoming ineligible or are to
            be made, but in such later case, only with respect to the period of
            time during which the Participant was an eligible Participant.

      (k)   In the event the Participant terminates employment by reason of
            Disability, the Participant may remain a Participant for the purpose
            of all Awards which shall have been made prior to the Participant's
            Disability or are to be made, but in such later case, only with
            respect to the period of time prior to the Disability.

      (l)   In the event the Participant terminates employment by Retirement,
            the Participant may remain a Participant for the purpose of all
            Awards which shall have been made


                                      -11-
<PAGE>
            prior to Retirement or are to be made, but in such later case, only
            with respect to the period of time during which the Participant was
            an Employee.

      (m)   In the event of the death of a Participant to whom an Award is to be
            or shall have been made, the Award or any portion thereof remaining
            unpaid may be paid to such Participant's Beneficiary either in the
            manner in which payment would have been made had the Participant not
            died or in such other manner as may be determined by the Committee.

SECTION 7. ADMINISTRATION

      (a)   The Plan and all Awards granted pursuant thereto shall be
            administered by the Committee so as to permit the Plan to comply

                  accordance with the objectives of this Program.

      (c)   The Committee may delegate to the officers or employees of the
            Company the authority to carry out any of its responsibilities under
            and described in this Plan, under such conditions or limitations as
            the Committee may


                                      -13-

            binding and conclusive on the Company, its Participating
            Subsidiaries, shareholders, Employees and Participants. No member of

            any action or determination made in good faith with respect to this
            Program, any Award, or any Award Agreement.

            extent that such ownership existed prior to the Corporate
            Transaction and (C) at least a majority of the members of the board
            of directors of the corporation resulting from such Corporate
