(ak)    Each of the components of the accrued benefit under this Plan (the Title I-related accrued benefit, the Title II-related accrued benefit, the Title III-related accrued benefit, and the Title IV-related accrued benefit) shall be expressed as a straight life annuity starting at the age that is the normal retirement age under the applicable title of the Retirement Plan in accordance with the following rules:

(i)If the annuity starting date for the relevant Retirement Plan benefit occurs on or before the required commencement date under this Plan, the Title I-related accrued benefit, the Title II-related accrued benefit, the Title III-related accrued benefit, or the Title IV-related accrued benefit, as is applicable, shall first be calculated as of the Retirement Plan annuity starting date related to that component benefit and then shall be converted actuarially to a straight life annuity payable at age 65 applying actuarial assumptions that are consistent with the relevant Title of the Retirement Plan. The component accrued benefit so calculated shall not be increased or decreased based on subsequent events.

(ii)If the annuity starting date for the relevant Retirement Plan benefit has not occurred on or before the required commencement date under this Plan, the Title I-related accrued benefit, the Title II-related accrued benefit, the Title III-related accrued benefit, or the Title IV-related accrued benefit, as is applicable, shall be calculated as if the relevant Retirement Plan benefit had an annuity starting date and a form of payment that is the same as the required commencement date and form of payment under this Plan. The resulting component benefit shall then be converted actuarially to an equivalent straight life annuity starting at age 65, and the component accrued benefit so calculated shall be the component accrued benefit under this Plan and shall not be increased or decreased based on subsequent events.

(al)The component accrued benefit described in subsection (f) above shall be converted to the actual benefit paid under this Plan applying the methodology specified in the

applicable title of the Retirement Plan. For this purpose, the terms of the applicable title of the Retirement Plan are those in effect as of the annuity starting date used in this Plan. If the applicable title of the Retirement Plan does not provide a methodology, a reasonable methodology, as determined by the Plan Administrator, shall be used.

If an Employee dies prior to the date his accrued benefit under this Plan would otherwise commence, this Plan shall provide a death benefit if the applicable title of the Retirement Plan provides a death benefit under that circumstance. Any death benefit under this Plan shall be paid in a lump sum on the first day of the first calendar month after death. If there is a delay in payment of the lump sum, regardless of the reason, the Plan shall not make an adjustment to reflect the time value of money. Except as described in the preceding sentence, the death benefit shall be the present value of the Employee’s entire accrued benefit under this Plan payable in accordance with the following rules:

(a)     The present value shall be paid to the Employee’s named primary Beneficiary or beneficiaries or, if applicable, to the Employee’s named contingent beneficiary or beneficiaries if the beneficiary or beneficiaries were named in a manner acceptable to the Plan Administrator.

(b)     If the Employee had not, prior to his death, named any beneficiary in a manner acceptable to the Plan Administrator, the present value shall be paid to the Employee’s estate.

(c)     The present value shall be paid in a lump sum and shall be calculated using the first of the month after death as the annuity starting date and applying the rules described in Section II(f) and (g) of this Plan for determining the amount to be paid.

(d)     If a beneficiary makes a “qualified disclaimer” as that term is defined in Section 2518 of the Code, and the Plan Administrator receives a copy of the disclaimer within 9 months after the employee’s death and before payment of the death benefit under this Plan, at the place designated by the Plan Administrator, the Plan will be administered as if the disclaiming beneficiary had died before the Employee.

Notwithstanding any provisions to the contrary, in order to comply with the terms of the Master Purchase and Sale Agreement (“Sale Agreement”) by which the ConocoPhillips Company acquired certain Alaskan assets of Atlantic Richfield Company, Inc. (“ARCO”), the following supplemental payments will be made:

(a)    The payments which would have been received under Article XXIV – ARCO Flight Crew of Title I of the Retirement Plan for those who were classified as an Aviation Manager, Chief Pilot, Assistant Chief Pilot, Captain or Reserve Captain as of July 31, 2000 if they had been eligible for those benefits under Title I of the Retirement Plan, except that if they receive a limited social security makeup benefit from Title I of the Retirement Plan it will be offset from the benefit payable from the Plan.

(b)    A final ARCO Supplemental Executive Retirement Plan (SERP) benefit will be calculated at the earlier of the time an Employee who had an ARCO SERP benefit terminates employment or, 2 years following the ARCO/BP Amoco p.l.c. merger, April 17, 2002

(“calculation date”). The SERP benefit attributable to service through July 31, 2000 shall be paid by BP Amoco p.l.c. and the difference shall be paid by this Plan. The SERP calculation will be done as if the Employee had continued to participate in the Atlantic Richfield Retirement Plan and SERP up to the calculation date. The ARCO Annual Incentive Plan (AIP) amount used will be:

    (i)    If the Employee terminates employment involuntarily prior to April 17, 2002, the highest of the actual AIP in the last 3 years including the AIP target payment amount for years after 1999 or the payment received under Phillips Annual Incentive Compensation Plan.

    (ii)    If the Employee terminates employment voluntarily prior to April 17, 2002, or if the calculation is made as of April 17, 2002, then the AIP will include the highest 3 year average using the highest of the actual AIP, the AIP target payment amount for years after 1999, or the payment received under Phillips Annual Incentive Compensation Plan. Any benefit paid by this Plan under this Section IV(b)(ii) and the SERP benefit paid by BP Amoco p.l.c. shall offset the benefit payable from this Plan.

The benefit under this Plan shall be calculated and paid as follows:

(a)    Commencement -- Unless the accrued benefit has been or will be paid on account of the Employee’s death as described in Section III, the present value of the Employee’s accrued benefit shall be paid in a lump sum on the later of: the Employee’s Plan-age 55 or the first

day of the seventh calendar month after the Employee’s Separation from Service; but in no event earlier than November 1, 2006.

(b)    Annuity Starting Date for calculating the present value:

    (i)    If the applicable commencement date for a Title I-related or a Title IV-related accrued benefit is the first day of the seventh calendar month after Separation from Service, the annuity starting date used in calculating the present value shall be the later of: the Employee’s Plan-age 55 or the first day of the first calendar month after the Employee’s Separation from Service; and the Plan shall pay interest from the annuity starting date to the commencement date at the 6 month T-Bill rate (as determined by the Plan Administrator) in effect on the annuity starting date. If the applicable commencement date for a Title-II-related accrued benefit is the first day of the seventh calendar month after Separation from Service, the annuity starting date shall be the same as the commencement date.

(ii)    Except as provided in the second sentence of this subsection (b)(ii), if the applicable commencement date is the Employee’s Plan-age 55 or November 1, 2006, the annuity starting date used in calculating the present value shall be the same as the commencement date. Provided, however, in the case of an Employee whose Separation from Service is in 2006 and whose commencement date under this Plan is November 1, 2006, the annuity starting date used in calculating the present value shall be the later of: the Employee’s Plan-age 55 or the first day of the first calendar month after the Employee’s Separation from Service; and the Plan shall pay simple interest from the annuity starting date to November 1, 2006,

at the 6 month T-Bill rate (as determined by the Plan Administrator) in effect on the annuity starting date.

(iii)    Except as specifically provided in subsections (b)(i) and (ii), the Plan shall not make an adjustment of the benefit to reflect the time value of money if there is delay in paying the benefit for any reason.

All amounts payable under this Plan shall be paid solely from the general assets of the Company and any rights accruing to an eligible Employee or beneficiary under the Plan shall be those of a general creditor; provided, however, that the Company may establish a grantor trust to satisfy part or all of its Plan payment obligations so long as the Plan remains an unfunded excess benefit plan and or an unfunded benefit plan for a select group of management or highly compensated employees for purposes of Title I of ERISA.

The right of an Employee, or beneficiary, or other person who becomes entitled to receive payments under this Plan, shall not be assignable or subject to garnishment, attachment or any other legal process by the creditors of, or other claimants against, the Employee, beneficiary, or other such person.

(a)    The Plan shall be administered by the Plan Administrator. The Plan Administrator may adopt such rules, regulations and forms as deemed desirable for administration of the Plan

and shall have the discretionary authority to allocate responsibilities under the Plan to such other persons as may be designated.

(b)    Any claim for benefits hereunder shall be presented in writing to the Plan Administrator for consideration, grant or denial. In the event that a claim is denied in whole or in part by the Plan Administrator, the claimant, within ninety days of receipt of said claim by the Plan Administrator, shall receive written notice of denial. Such notice shall contain:

    (1)    a statement of the specific reason or reasons for the denial;

    (2)    specific references to the pertinent provisions hereunder on which such denial is based;

    (3)    a description of any additional material or information necessary to perfect the claim and an explanation of why such material or information is necessary; and

    (4)    an explanation of the following claims review procedure set forth in paragraph (c) below.

(c)    Any claimant who feels that a claim has been improperly denied in whole or in part by the Plan Administrator may request a review of the denial by making written application to the Trustee. The claimant shall have the right to review all pertinent documents relating to said claim and to submit issues and comments in writing to the Trustee. Any person filing an appeal from the denial of a claim must do so in writing within sixty days after receipt of written notice of denial. The Trustee shall render a decision regarding the claim within sixty days after receipt of a request for review, unless special circumstances require an extension of time for processing, in which case a decision shall be rendered within a reasonable time, but not later than 120 days after receipt of the request for review. The decision of the Trustee shall be in writing and, in the case of the denial of a claim in whole

or in part, shall set forth the same information as is required in an initial notice of denial by the Plan Administrator, other than an explanation of this claims review procedure. The Trustee shall have absolute discretion in carrying out its responsibilities to make its decision of an appeal, including the authority to interpret and construe the terms hereunder, and all interpretations, findings of fact, and the decision of the Trustee regarding the appeal shall be final, conclusive and binding on all parties.

(d)    Compliance with the procedures described in paragraphs (b) and (c) shall be a condition precedent to the filing of any action to obtain any benefit or enforce any right which any individual may claim hereunder. Notwithstanding anything to the contrary in this Plan, these paragraphs (b), (c) and (d) may not be amended without the written consent of a seventy-five percent (75%) majority of Participants and Beneficiaries and such paragraphs shall survive the termination of this Plan until all benefits accrued hereunder have been paid.

Participation or nonparticipation in this Plan shall neither adversely affect any person's employment status, or confer any special rights on any person other than those expressly stated in the Plan. Participation in the Plan by an Employee of the Company or of a Participating Subsidiary shall not affect the Company's or the Participating Subsidiary's right to terminate the Employee's employment or to change the Employee's compensation or position.

(a)    The Board reserves the right to amend or terminate this Plan at any time, if, in the sole judgment of the Board, such amendment or termination is deemed desirable; provided that the Company shall remain liable for any benefits accrued under this Plan prior to the date of amendment or termination.

(b)    Except as otherwise provided herein, the Plan shall be binding upon the Company, its successors and assigns, including but not limited to any corporation which may acquire all or substantially all of the Company's assets and business or with or into which the Company may be consolidated or merged.

(c)    No amount accrued or payable hereunder shall be deemed to be a portion of an Employee's compensation or earnings for the purpose of any other employee benefit plan adopted or maintained by the Company, nor shall this Plan be deemed to amend or modify the provisions of the Retirement Plan.

(d)    The Plan shall be construed, regulated, and administered in accordance with the laws of the State of Texas except to the extent that said laws have been preempted by the laws of the United States.

(e)    Notwithstanding anything herein to the contrary, any right or interest of a Participant under this Plan is subject to forfeiture or recoupment, in whole or in part, under applicable law, including the Sarbanes-Oxley Act and any pertinent Company policies, including the Phillips 66 Clawback Policy. A Participant’s rights or interests are also subject to forfeiture or recoupment in the event a Participant’s negligence or misconduct results in materially misstated financial or other data, as determined by the Human Resources & Compensation Committee and the Audit & Finance Committee of the Board. If the Plan

Administrator determines that, subsequent to the receipt of benefits, the Participant has engaged or is engaging in any activity which, in the sole judgment of the Plan Administrator, is or may be detrimental to the Company, the Plan Administrator may forfeit and/or recoup any previously paid benefits.

(i)    The difference between the Select New Hire's total accrued benefit under Title I and his actual accrued benefit under Title I. For this purpose, a Select New Hire's total accrued benefit under Title I is the accrued benefit he would have if his accrued benefit under Title I were determined under the terms of Title I but with the following modifications:

(aa)    Include in Annual Earnings an award under the Incentive Compensation Plan which the Select New Hire deferred under the terms of KEDCP. Include such award in the calendar year in which the award would have been paid to the Select New Hire if it had not been deferred.

(bb)    Include in Annual Earnings salary that would have been paid to the Select New Hire but for the fact that he voluntarily elected to defer receipt of that salary under the terms of KEDCP.

Provided, however, this subsection (gg) shall be disregarded to the extent the benefit created solely by operation of this subsection (gg) is provided under the terms of Title 1.

(hh)    Determine service credited for purposes of benefit accrual as if the Select New Hire had originally been employed by the Controlled Group on the date that the Select New Hire began employment with the company with which the Select New Hire was employed immediately prior to becoming employed by the Controlled Group.

(ii)    In the case of a Select New Hire who terminated employment on or after February 8, 1993, the Title I-related accrued benefit shall include an additional supplemental accrued benefit calculated under the terms of Title I, but disregarding the limitation on compensation that is taken into account, using as final average earnings the difference, if any, between the Total Final Average Earnings and the Final Average Earnings used in Title 1.

(iii)    The Title I-related accrued benefit shall also include any benefit provided under Section IV of this Plan.

4.    The Offsetting Benefits shall mean any benefit, other than the Further Benefit, provided to the Select New Hire under a defined benefit plan of Phillips 66, including but not limited to the Phillips 66 Retirement Plan (and any successor plan) and the Phillips 66 Key Employee Supplemental Retirement Plan (and any successor plan), together with any benefit provided to the Select New Hire under a "defined benefit plan" (as defined in section 3(35) of the Employee Retirement Income Security Act of 1974, as amended (ERISA)), including any such plan regardless of whether it might also be considered an "excess benefit plan" as defined in section

3(36) of ERISA, of the company by which the Select New Hire was employed immediately prior to becoming an employee of the Controlled Group. In determining the value of a benefit provided by an employer which is not a member of the Controlled Group, the Plan Administrator may make any reasonable assumptions necessary and use such information as may be publicly available, provided by such employer, or provided by the Select New Hire, although it is within the discretion of the Plan Administrator to determine which such information and assumptions to use and to disregard any information which the Plan Administrator considers invalid, incomplete, or otherwise suspect.

5.    Nothing in this Appendix is intended to affect the other operations or provisions of the Plan. If the Select New Hire is, under the provisions of the Plan, otherwise eligible to participate in the Plan, the Select New Hire will do so in accordance with those provisions.
