               Participant under this subparagraph shall be computed by
               reference to the Attachment 1 matrix, provided, however, that
               upon a Change of Control, notwithstanding anything to the

     5.2  The Company reserves the right to offset the allowance described in
          Paragraph 5.1, above, by any monies the Employee owes the Company and
          by the amount of any statutory benefits attributable to termination of
          employment or disability, provided, however, that the Company shall
          not have such offset right after a Change of Control.

     5.3  Notwithstanding anything in this Plan to the contrary, the total
          allowance paid under this Plan shall not exceed the equivalent of
          twice the Employee's annual compensation as defined in ERISA
          Regulation (S) 2510.3.2(b)(a)(i) during the year immediately preceding
          the Employee's termination of employment, provided, however, this
          limitation shall not apply to Tier 1 and 2 Employees and any other
          person who is a member of a select group of management or highly
          compensated employees as such terms are used in Section 201(a) of
          ERISA.

4.   Sections 6, 7 and 8 of the Plan are renumbered as Sections 7, 8 and 9 and a
     new Section 6 is added to the Plan to read as follows:

                                       4

 
                                  "SECTION 6
               ALLOWANCES PAYABLE FOLLOWING A CHANGE OF CONTROL

     6.1  Notwithstanding any other provision of the Plan, if an Employee
          terminates employment during the Benefit Trigger Window under the
          circumstances described in Paragraph 6.2 (a "Terminated Employee"),
          the Terminated Employee will be paid a single cash allowance as
          described in Paragraph 6.3 and, if applicable, Paragraph 6.6, within
          60 days following such termination in lieu of any other benefit to
          which the Employee is entitled under this Plan.

     6.2 For the purposes of Paragraph 6.1 above, termination of employment
         shall mean:

          (a)  a termination of employment during the Benefit Trigger Window by
               the Surviving Entity, other than for Cause, or

          (b)  the Employee's voluntary termination within the Benefit Trigger
               Window as a result of the Surviving Entity's implementation of:

               (i)  a ten percent or more reduction of such Employee's
                    Qualifying Pay from the Qualifying Pay determined as of the
                    date immediately prior to the date of the Change of Control
                    or a ten percent or more reduction (based on dollar value)
                    in the Employee's aggregate Qualifying Pay plus Target Award
                    ("Total Pay") from the Employee's Total Pay determined as of
                    the date immediately prior to the date of the Change of
                    Control; or

               (ii) a required relocation of the Employee's principal place of
                    work to a location which would satisfy the conditions
                    specified in (S) 217(c)(1) of the Internal Revenue Code of
                    1986, as amended (the "Code"), for 

                                       5

 
                    a deduction by such Employee of moving expenses under (S)
                    217 of the Code.
 
          (c)  No Employee shall be deemed to have a termination of employment
               solely due to a transfer of employment directly between the
               Company, a Surviving Entity or any of their affiliates.

     6.3  Following termination of employment of an Employee, as defined in
          Paragraph 6.2, a cash payment shall be made to the Terminated Employee
          as prescribed under the following payment schedule, in lieu of any
          other benefit to which the Employee is entitled under this Plan
          (except for the benefit described in Section 6.6 hereof):
 
 
                   EMPLOYEE
                   LEVEL                   CASH PAYMENTS
            ------------------------------------------------------
                   Tier 1           3 times the Covered Amount
            ------------------------------------------------------
                   Tier 2           2 times the Covered Amount
            ------------------------------------------------------
                   Tier 3           The greater of 1 times the
                                    Covered Amount or Basic STAP
            ------------------------------------------------------
                   All others       Basic STAP
            ======================================================

     6.4 Notwithstanding anything to the contrary in this Plan, if a Change of
         Control as described under paragraph (3) of the definition of such term
         on Annex A attached hereto (an "ARCO Acquisition") occurs, no person
         shall be entitled to benefits under Paragraphs 6.3 or 6.6 of this Plan
         as a result of such a Change of Control, but shall instead receive the
         benefits to which the person may otherwise be entitled, whether under
         this Plan or any other employee welfare benefit plan, as determined in
         the sole discretion of Atlantic Richfield Company; provided that
         benefits accrued under this


                                       6

 
         Plan due to a termination of employment prior to a Change of Control,
         but not yet paid, shall be paid in accordance with the terms of this
         Plan in existence immediately prior to the Change of Control.

     6.5 Upon the earlier to occur of an Anticipatory Change of Control or a
         Change of Control (excluding an ARCO Acquisition), the Company or any
         successor to the obligations of the Company shall fund the Change of
         Control Trust in accordance with its terms.

                                       7

 

     6.6 Special Tax Allowance and Tax Mitigation.

         (a)   If a Participant in Tier 1 (or who was in Tier 1 immediately
               prior to an ARCO Acquisition) is liable for the payment of any
               excise tax (the "Basic Excise Tax") because of Section 4999 of
               the Code, or any successor or similar provision relating to a
               Change of Control, with respect to any payments or benefits
               received or to be received from the Company or its affiliates, or
               any successor to the Company or its affiliates, whether provided
               under this Plan or otherwise, the Company or any successor to the
               obligations of the Company will pay the Participant an amount
               (the "Special Reimbursement") which, after payment by such
               Participant (or on the Participant's behalf) of any federal,
               state and local taxes applicable thereto, including, without
               limitation, any further excise tax under such Section 4999 of the
               Code, on, with respect to or resulting from the Special
               Reimbursement, equals the net amount of the Basic Excise Tax.
               The Special Reimbursement will be paid upon receipt by the
               Participant of any payment or benefit that will result in the
               Basic Excise Tax.

          (b)  Notwithstanding anything in this Plan to the contrary, if any
               amounts due to a Participant other than a Tier 1 Participant
               under this Plan and any other plan or program of the Company or
               its affiliates constitute a "parachute payment," as such term is
               defined in Section 280G(b)(2) of the Code, and the amount of the
               parachute payment, reduced by all federal, state and local taxes
               applicable thereto, including the excise tax imposed pursuant to
               Section 4999 of the Code, is less than the amount the Employee
               would receive if he were

                                       8

 
               paid three times his "base amount," as defined in Section
               280G(b)(3) of the Code, less one dollar, reduced by all federal,
               state and local taxes applicable thereto, then the aggregate of
               the amounts constituting the parachute payment shall be reduced
               to an amount that will equal three times his base amount less one
               dollar.

          (c)  The determinations to be made with respect to this Paragraph 6.6
               will be made by the Special Plan Administrator."

5.   Paragraphs 8.2 and 8.3 of the Plan are amended to read as follows:

    "8.2  The cost of this Plan shall be paid by the Company out of its general
          assets provided that any benefits due from the Company under Section 6
          of the Plan shall be paid from the Change of Control Trust, and if not
          paid from the Change of Control Trust shall be paid by the Company or
          any successor to the obligations of the Company.

     8.3  This Plan is intended to be an employee welfare benefit plan, as
          defined in (S) 3(1), Subtitle A of Title I of Employee Retirement
          Income Security Act of 1974, as amended ("ERISA"), except that
          payments to any Employee who is a member of a select group of
          management or is highly compensated shall be deemed to be made under a
          plan which is unfunded and maintained primarily for the purpose of
          providing deferred compensation for a select group of management or
          highly compensated employees within the meaning of (S) 201(2) of
          ERISA." 

5.   Section 8 of the Plan is amended by adding the following Paragraph 8.4
     thereto to read as follows:

     "8.4 Any action required to be taken under this Plan by the Chief
          Financial Officer and the General Counsel of the Company may be taken
          by either individual if the other

                                       9

 
          position is then vacant, and if both positions are vacant, such action
          may be taken by any other officer of the Company with a position of
          vice president or above. Any action required to be taken by the Vice
          President, Human Resources of the Company may, if such position is
          vacant, be taken by any other officer of the Company with a position
          of vice president or above."

6.   Section 9 of the Plan is amended to read as follows:

                                  "SECTION 9
                           AMENDMENT AND TERMINATION

     9.1  Amendment or Termination Generally.   Except as provided in Paragraphs
          9.2 and 9.3, the Plan may be amended for any reason and at any time by
          the Vice President, Human Resources of the Company.  Except as
          provided in Paragraphs 9.2 and 9.3, the Plan and payments thereunder
          may be terminated at any time by the Vice President, Human Resources
          of the Company; provided, however, that no amendment may deprive a
          Participant of benefits that have previously accrued.

     9.2  Amendment or Termination during Anticipatory Change of Control. The
          Plan may not be terminated or amended during the period after the
          occurrence of an Anticipatory Change of Control and prior to a Change
          of Control or an Anticipatory Change Termination (as defined in
          Section 3.1), except that the Board of Directors of the Company may
          amend the Plan during such a period as it may deem reasonably
          necessary, provided that, if any such amendment reduces, or could
          reduce, the value of any benefit of a Participant, as determined in
          the sole discretion of the Special Plan Administrator, the Company or
          any successor to the obligations of the Company shall, prior to, and
          as a condition precedent to, such amendment going into effect,

                                       10

 
          provide substantially equivalent value in replacement thereof to the
          Participant in the reasonable determination of the Special Plan
          Administrator.

     9.3  Amendment or Termination On or After a Change of Control.  The Plan
          may not be terminated or amended on or after a Change of Control in
          any manner that would negatively affect Employee's rights arising as a
          result of the Change of Control under Section 6 without the consent of
          all of the Participants or, in the alternative, the Participants whose
          Plan benefits are affected by such termination or amendment.  The Plan
          will terminate at the expiration of the Benefit Trigger Window,
          provided, however, that such termination shall not affect any right of
          a Participant which shall have accrued prior to such termination.

     9.4  Acquisition by ARCO.  An ARCO Acquisition shall not be treated as a
          Change of Control for purposes of this Section 9."

     Executed as of the 10th day of March, 1999.
