     MPS Plan as of the time of the commencement of monthly
     retirement income to the Employee under the UtiliCorp
     United Inc. Retirement Income Plan (UtiliCorp Plan),
     assuming:

               (i)  the Employee had remained a participant

          with the Corporation;

               (ii) the Employee's years of Credited

          combined actual years of Credited Service and Service
          under the MPS Plan and the UtiliCorp Plan; provided,
          however, no years of Credited Service and Service
          shall be counted under both the MPS Plan and UtiliCorp
          Plan for the same period of employment; and

               (iii)     the provision of the MPS Plan as of
          July 31, 1988 (including those provisions reducing the
          Employee's accrued benefit in the event his retirement
          benefits commenced prior to his attainment of age (62)
          remained unchanged.

               (b) An amount equal to the sum of:

          accrued benefits under the UtiliCorp Plan as of the
          time of the commencement of monthly retirement income
          to the Employee under said Plan, calculated in accor-
          dance with the provisions of the UtiliCorp Plan, (in-
          cluding those provisions reducing the Employee's
          accrued benefit in the event his retirement benefits
          commence prior to his attainment of age 62); and

                    (ii) the value of the Employee's plan
          account(s) in the UtiliCorp United Inc. Employee Stock

          value of Corporation common stock or other employer
          securities in the Employee's ESOP plan account(s)
          shall be determined in the same manner for purposes of
          this Agreement as under the ESOP.

     (B)  An amount equal to the excess of (a) over (b):

               (a)  An amount equal to the present value of the
     Employee's accrued benefits under the UtiliCorp Plan as of
     the time of the commencement of monthly retirement income

     isions reducing the Employee's accrued benefit in the event
     his monthly retirement income commences prior to his
     attainment of age (62), but with the addition of 6.74 years
     of benefit accrual service (Credited Service).

               (b)  An amount equal to the present value of the
          Employee's accrued benefits under the UtiliCorp Plan as of
          the time of the commencement of monthly retirement income
          under the UtiliCorp Plan, Calculated in accordance with the
          provisions of the UtiliCorp Plan (including those pro-
          visions reducing the Employee's accrued benefit in the
          event his monthly retirement income commences prior to his
          attainment of age 62).

          For purposes of this paragraph, the present value of the
     Employee's accrued benefits shall be calculated using the same
     interest rate assumption as is used for determining the actu-
     arial value of benefits under the UtiliCorp Plan as of the time
     monthly retirement income commences to the Employee under the
     UtiliCorp Plan.

          2.   EFFECT OF EARLY ESOP DISTRIBUTIONS.

               Notwithstanding subparagraph 1(A) (b) (ii),  if the Employee
     should receive a distribution from the ESOP prior to the time
     monthly retirement income commences to the Employee under the
     UtiliCorp Plan, the value of such distribution determined as of the
     date of the distribution shall be added to the total amount
     described in subparagraph 1(A) (b) in determining the amount of the
     Employee's supplemental retirement benefit.

          3.   PAYMENT OF BENEFITS.

               No benefit payments will commence under this Agreement prior
     to the Employee's termination of employment with the Corporation.
     Benefits under this Agreement shall be paid by the Corporation in
     the same manner and at or about the time benefits are paid to the
     Employee under the UtiliCorp Plan in accordance with elections made
     by the Employee under the UtiliCorp Plan.  Such benefit payments
     shall be the actuarial equivalent of the amount described in para-
     graph 1 using the same assumptions for determining actuarial equiva-
     lents as described in the UtiliCorp Plan at the time of the Em-
     ployee's retirement.

          4.   DEATH BENEFITS FOR SPOUSE.

               Should the Employee die before the commencement of monthly
     retirement income under the UtiliCorp Plan, a monthly benefit shall
     be payable to his surviving spouse, if any, for her life, commencing
     as of the date that death benefits commence to the spouse under the
     UtiliCorp Plan.  The amount of such monthly benefit shall be equal
     to 50% of the monthly benefit that would have been payable to the
     Employee under this Agreement during his lifetime had he elected to
     retire as of the date of his death and receive payments under the
     UtiliCorp Plan in the form of a 50% joint and survivor annuity with
     his surviving spouse as beneficiary.

          5.   NO CONTRACT OF EMPLOYMENT.

          Nothing contained herein shall be construed to be a contract
     of employment for any term of years, nor as conferring upon the Em-
     ployee the right to continue in the employ of the Corporation in his
     present capacity, or in any other capacity.

          6.   BENEFITS PAYABLE ONLY FROM CORPORATE ASSETS.

               (a)  Nothing contained in this Agreement, and no action
     taken pursuant to its provisions by either party shall create or be
     construed to create, a trust of any kind, or a fiduciary relationship
     between the Corporation and the Employee or any other person.

               (b)  The payments to the Employee or his surviving spouse
     shall be made from assets which shall continue for all purposes to
     be a part of the general assets of the Corporation and no person
     shall acquire any interest in such assets by virtue of this Agree-
     ment.  To the extent the Employee or his surviving spouse acquires a
     right to receive payments from the Corporation under this Agreement,
     such right shall be no greater than the right of any unsecured gen-
     eral creditor of the Corporation.

          7.   NON-ASSIGNABILITY OF BENEFITS.

               Neither the Employee nor his spouse shall have the power or
     right to transfer, assign, anticipate, hypothecate or otherwise en-
     cumber all or any part of the amounts payable by the Corporation
     hereunder.  Such amounts shall not be subject to seizure by any
     creditor of the Employee, by a proceeding at law or in equity, nor
     transferable by operation of law in the event of bankruptcy, insol-
     vency or death of the Employee or his spouse.  Notwithstanding any
     provision to the contrary in this Agreement, any such attempted
     assignment, transfer or encumbrance shall be void.

          8.   AMENDMENT.

               This Agreement may not be amended, altered or modified, ex-
     cept by a written instrument signed by both parties and may not be
     terminated, except as provided herein.

          9.   GOVERNING LAW.

               This Agreement, and the rights of the parties hereunder,
     shall be governed by and construed in accordance with the laws of
     the State of Missouri.

          IN WITNESS WHEREOF, the parties have executed this Agreement, in
     duplicate, as of the date first written above.
