                             EXCESS BENEFIT PLAN

                   Amended and Restated as of July 1, 1996
                   ---------------------------------------


SECTION 1.   INTRODUCTION.
- ---------    -------------

   The Chevron Corporation Excess Benefit Plan (the "Excess Benefit Plan") was
originally established effective January 1, 1976.  Effective as of July 1,
1996, the Excess Benefit Plan was last amended and restated to read as set
forth herein.  The purposes of the Excess Benefit Plan are:  (i) to supplement
benefits provided under the Retirement Plan, to the extent such benefits are
reduced as a result of the limitation on regular earnings imposed under section
401(a)(17) of the Code or the limitations on annual pension benefits imposed
under section 415 of the Code; (ii) to provide retirement benefits that take
into account Unrestricted Awards made under the MIP, the Aramco ICP and the
Caltex ICP, and salary deferrals under the Salary Deferral Plan; and (iii) to
supplement employer-provided benefits under the PS/SP to the extent such bene-
fits are reduced as a result of the limitation on regular earnings imposed
under section 401(a)(17) of the Code, the dollar limitation on "annual
additions" imposed under section 415(c)(1)(A) of the Code or salary deferrals
under the Salary Deferral Plan.

SECTION 2.   ELIGIBILITY AND PARTICIPATION.
- ---------    ------------------------------

   Participation in the Excess Benefit Plan shall be limited to:

      (i) All Members of the Retirement Plan whose benefits thereunder are
   reducedbecause of the limitations imposed under section 401(a)(17) or 415
   of the Code;

      (ii) All Members of the Retirement Plan who receive Unrestricted Awards
   under the MIP, the Aramco ICP or the Caltex ICP;

      (iii) All Members of the Retirement Plan or PS/SP who defer salary under
   the Salary Deferral Plan; and

      (iv) All Members of the PS/SP whose allocations of Company Contributions
   and Allocable Forfeitures thereunder are reduced because of the limitations
   imposed under section 401(a)(17) or 415(c)(1)(A) of the Code.

SECTION 3.   PLAN BENEFITS.
- ---------    --------------

   Plan Benefits under the Excess Benefit Plan shall consist of the Retirement
Excess Benefit and the PS/SP Excess Benefit.  No

                                     -1-


Participant shall be entitled to Plan Benefits until the Participant ceases to
be an Employee.

   (a) Retirement Excess Benefit.  A Participant's Retirement Excess Benefit
       -------------------------
shall be the sum of (i) and (ii) below:

      (i)  The lump sum value of an Individual Life Pension, determined by
   subtracting the Individual Life Pension to which the Participant is entitled
   under the Retirement Plan from the Individual Life Pension to which the
   Participant would be entitled thereunder without regard to the Section
   401(a)(17) and Section 415 Reductions and the Participant's salary deferrals
   under the Salary Deferral Plan.  In addition, a Participant's Retirement
   ExcessBenefit shall include any Interest payable under the Retirement Plan
   that may not be paid from that Plan because of the limitations imposed under
   section 415 of the Code.  Any such Interest shall be paid or credited, as
   appropriate, at the time payments are made from the Retirement Plan.

      (ii)  The lump sum value of an Individual Life Pension, determined as
   follows:

         (A) The Participant's MIP Excess Benefit Earnings shall be determined
      by subtracting the Participant's Highest Average Earnings from the amount
      that would constitute the Participant's Highest Average Earnings if the
      Participant's Unrestricted Awards under the MIP, the Aramco ICP and the
      Caltex ICP, as determined by the Committee in its sole discretion, were
      taken into account as Regular Earnings.

         (B) "Unrestricted Awards" with respect to the MIP means any awards
      under the MIP that are not subject to forfeiture conditions established
      by the Committee (other than the forfeiture conditions expressly
      described in the text of the MIP).  "Unrestricted Awards" with respect to
      the Aramco ICP means any awards under the Aramco ICP that are taken into
      account under the Aramco Plan prior to 1989.  "Unrestricted Awards" with
      respect to the Caltex ICP means any awards under the Caltex ICP that are
      taken into account under the Caltex Plan.

         (C) Each Unrestricted Award under the MIP shall be deemed paid in
      equal monthly installments for that portion of the MIP Award Year during
      which the Participant was an Employee and a participant in the MIP,
      without regard to when the Participant is informed of such Award or when
      such Award is actually paid.  If an Unrestricted Award under the MIP is
      made after the

                                     -2-


      close of the applicable MIP Award Year, if necessary, the
      Committee shall recalculate the Participant's Plan Benefit solely for the
      purpose of taking such Award into consideration.  For purposes of any
      such recalculation, the Committee shall not credit the Participant with
      any interest nor make any other change in the methods, factors or
      assumptions used in the original calculation.  All Unrestricted Awards
      under the Aramco ICP and/or the Caltex ICP shall be deemed paid in equal
      monthly installments for that portion of the award year under the Aramco
      Plan and the Caltex Plan, respectively, during which the Participant was
      a participant in such Plan.

         (D) The Participant's MIP Credited Service shall be that portion of
      the Participant's Period of Service which is taken into account in
      computing the Participant's Plan Benefit under the Retirement Plan,
      excluding all service prior to the date on which the Participant reaches
      age 25 that occurs before July 1, 1986.

         (E) An Individual Life Pension shall be determined under the
      applicable formula set forth in sections 3(c), 4(c) and 6(d) of the
      Retirement Plan, on the basis of the Participant's MIP Excess Benefit
      Earnings and MIP Credited Service, without regard to any Social Security
      Offset provided in such formula.

   (b) Calculation of Retirement Excess Benefit.
       -----------------------------------------
      (i) The lump sum value of a Participant's Retirement Excess Benefit shall
   be the present value of the Individual Life Pension described in Section
   3(a) above.  Such present value shall be computed under whichever of the
   following rules is applicable:

         (A) If the Participant elects to have his or her Plan Benefit under
      the Retirement Plan paid in the form of a monthly pension, such present
      value shall be computed under the rules and assumptions that would be
      used for calculating the payment of such Individual Life Pension under
      the Lump Sum Option of the Retirement Plan, based on the Participant's
      age and the interest rates in effect on the first day of the first month
      for which the Retirement Plan pension is paid; or

         (B) If the Participant elects to have his or her Plan Benefit under
      the Retirement Plan paid under the Lump Sum Option, such present value
      shall be computed under the same rules and assumptions and shall be
      determined as of the same

                                     -3-


      date used for the calculation of the basic amount of the lump sum payment
      from the Retirement Plan.

      (ii) Interest shall accrue on the unpaid portion, if any, of a
   Participant's Retirement Excess Benefit, commencing on the last day of the
   month after the month as of which the lump sum value of such Excess Benefit
   is calculated.  If a Participant receives an Unrestricted Award under the
   MIP after termination of employment, any additional Retirement Excess
   Benefit attributable to that Award shall accrue interest commencing as of
   the first day of the month after the month in which the Award is granted.
   Interest shall be credited and compounded at the end of each Quarter at a
   rate equal to the average market yield for the preceding Quarter on U.S.
   Government 10-year bonds, constant maturity, as published by Data Resources
   Inc. in Data Resources Review of the U.S. Economy, or in such other source
           -----------------------------------------
   as the Committee may from time to time prescribe.

   (c) PS/SP Excess Benefit.  A Participant's PS/SP Excess Benefit shall be the
       --------------------
lump sum value of a Participant's Stock Units, determined as follows:

      (i) The Committee shall establish a PS/SP Excess Benefit Account for each
   Participant whose share of Company Contributions and Allocable Forfeitures
   under the PS/SP is reduced for any Quarter on account of the Section
   401(a)(17) or Section 415(c)(1)(A) Reductions or on account of deferrals
   under the Salary Deferral Plan.  Stock Units shall be credited to such
   Account as set forth in (ii) and (iii) below.

      (ii) As of the last day of each Quarter, each Participant's PS/SP Excess
   Benefit Account shall be credited with the number of Stock Units determined
   by subtracting the amount of Company Contributions and Allocable Forfeitures
   allocated to such Participant's Accounts under the PS/SP for such Quarter
   from the amount of Company Contributions and Allocable Forfeitures that
   would have been allocated to such Participant for such Quarter without
   regard to the Section 401(a)(17) and Section 415(c)(1)(A) Reductions and the
   Participant's deferrals under the Salary Deferral Plan, and by dividing the
   resulting amount by the per share price used in allocating the Company
   Profit Sharing Contribution or ESOP Contribution under the PS/SP for such
   Quarter.

      (iii) As of the last day of each Quarter in which a cash dividend is paid
   with respect to shares of Chevron Stock, each Participant's PS/SP Excess
   Benefit Account shall be credited with the number of Stock

                                     -4-



   Units determined by multiplying the number of Stock Units in such Account on
   the appropriate dividend payment date by the per share amount of such
   dividend, and by dividing the resulting amount by the per share price used
   in allocating the Company Profit Sharing Contribution or ESOP Contribution
   under the PS/SP for such Quarter.

      (iv) No PS/SP Excess Benefit shall become payable hereunder unless the
   Participant is fully vested in his or her Contingent Account under the
   PS/SP.

   (d) Integration with Gulf SPP Benefits.  The Retirement Excess Benefit of 
       ----------------------------------
any Participant who is an Eligible Employee under the Gulf SPP shall be reduced
as follows.  Before conversion to a present lump sum value, the Individual Life
Pension determined under Section 3(a) above with respect to the Participant's
MIP Credited Service completed before July 1, 1986, shall be reduced (but not
below zero) by the Participant's net Gulf SPP individual life pension
(determined after the application of all offsets under the Gulf SPP for
qualified pension plan benefits).  Any Spouse-Pension or Gulf Retirement Bonus
provided under the Gulf SPP shall be ignored.

SECTION 4.   DISTRIBUTION OF PLAN BENEFITS.
- ---------    ------------------------------

   Distribution of Plan Benefits hereunder shall be made in cash after the
Participant ceases to be an Employee at such time or times as the Committee
shall determine in its sole discretion.  The Committee has established the fol-

   scheduled to be made within such 12-month period pursuant to Section
   4(a)(ii) above shall be made without regard to the request made pursuant to
   this Section 4(a)(iii):

         (A)   In a lump sum in any January, April, July or October after the
      Participant ceases to be an Employee, but not later than the first

      the date the Participant ceases to be an Employee;

         (B)   In fifteen or fewer approximately equal annual installments,

   may only be changed by the Committee.  A Participant may request such a
   change by describing to the Committee in writing the Participant's reason

   showing of hardship or significantly changed circumstances based on
   substantial evidence.

                                     -6-


      (vii) In the event that a Participant receives an Unrestricted Award
   under the MIP after the date distribution of such Participant's Retirement
   Excess Benefit is made or commenced pursuant to Section 4(a)(ii) or (iii)
   above, the following rules shall apply:

         (A) If the Participant received a single payment pursuant to Section
      4(a)(iii)(A) above, the additional Retirement Excess Benefit attributable
      to such Unrestricted Award under the MIP shall be paid in a lump sum as
      soon as practicable; and

         (B) If the Participant commenced to receive installment payments
      pursuant to Section 4(a)(ii) or (iii)(B) above, such Participant's future
      installment payments shall be recalculated to reflect the additional
      Retirement Excess Benefit attributable to such Unrestricted Award under
      the MIP.

   (b) PS/SP Excess Benefit.
       ---------------------

      (i) Unless the Committee approves a Participant's distribution request
   pursuant to Section 4(b)(ii) below, distribution of the value of the Stock
   Units credited to the Participant's PS/SP Excess Benefit Account shall
   commence in the first January, April, July or October that is at least 12
   months after the Participant ceases to be an Employee and shall be made in
   ten approximately equal annual installments.

      (ii) At any time a Participant may make a request for distribution at the
   time and in the manner described in (A) or (B) below by filing the

   Units credited to the Participant's PS/SP Excess Benefit Account shall be
   made in accordance with the first such request made after December 31, 1996,
   unless the Committee has disapproved the Participant's request or has
   determined that the distribution shall be made at some other time; provided,
   however, that (1) no distribution may be made pursuant to such request
   within the 12-month period commencing on the date the request is filed with
   the Committee and (2) any distribution scheduled to be made within such
   12-month period pursuant to Section 4(b)(i) above shall be made without
   regard to the request made pursuant to this Section 4(b)(ii):

         (A)   In a lump sum in any January, April, July or October after the
      Participant ceases to be an Employee, but not later than

                                     -7-


      the first January
      after the later of the date the Participant attains age 70 1/2 or the date
      the Participant ceases to be an Employee;

   disapproved the request or has determined that the distribution shall be
   made at some other time.

      (iv) The amount of a cash payment pursuant to Section 4(b)(i) or (ii)
   shall be determined by dividing the number of Stock Units credited to the
   Participant's PS/SP Excess Benefit Account as of the close of the Quarter
   preceding the distribution date by the number of annual payments remaining
   to be made, and by converting the resulting number of Stock Units to a cash
   amount by multiplying such number of Stock Units by the closing price of
   Chevron Stock on the last day the New York Stock Exchange is open during
   Quarter preceding the distribution date (as reported in the Composite
   Transaction Report).

      (v) The time of distribution pursuant to Section 4(b)(i) or (ii) above

   her PS/SP Excess Benefit shall be distributed to the Participant's
   Beneficiary in accordance with Section 5(c).

   (c) Beneficiaries.  A Participant may designate on the prescribed form filed
       -------------
with the Committee one or more Beneficiaries to receive payment of any Plan
Benefits hereunder that become distributable after the Participant's death.  A
Participant may change such designation at any time by filing the prescribed
form with the Committee.  If a Beneficiary has not been designated or if no
designated Beneficiary survives the Participant, distribution will be made to
the Participant's surviving spouse as Beneficiary if such spouse is then living
or, if not, in equal shares to the then living children of the Participant as
Beneficiaries or, if none, to the Participant's estate as Beneficiary.  Distri-
butions under this Section 5(c) will be made in such manner and at such times
as the Committee shall determine in its sole discretion.  Unless the Committee
directs otherwise, the elections provided in Section 4 may be made by the
Beneficiary following the Participant's death.

SECTION 6.   MISCELLANEOUS.
- ---------    --------------
   (a) Forfeitures.  Plan Benefits which are unpaid shall be forfeited under
the following circumstances:

      (i) If the Participant is dismissed for cause or otherwise ceases to be
   an Employee at a time when a basis for such dismissal exists; or

      (ii) If, before or after the Participant ceases to be an Employee, the
   Participant engages in any activity which, in the opinion of the Committee,
   is prejudicial to the interests of any member of the Affiliated Group; or

      (iii) If the Participant is indebted to any member of the Affiliated
   Group at the time he or she becomes entitled to payment of a Plan Benefit
   hereunder.  In such a case, to the extent that the amount of the Plan
   Benefit does not exceed such indebtedness, the amount of such Plan Benefit
   shall be forfeited and the Participant's indebtedness shall be extinguished
   to the extent of such forfeiture.  The Committee in its sole discretion
   shall determine how and why such forfeiture shall be effected, including
   the valuation of any Stock Units credited to the Participant's PS/SP Excess
   Benefit Account.  Any forfeiture under this Section 6(a)(iii) shall be
   deemed to come first from the Participant's Retirement Excess Benefit and
   then from his or her PS/SP Excess Benefit.

   (b) Funding.  The Excess Benefit Plan shall be unfunded, and all Plan
       -------
Benefits shall be paid only from the general assets of Chevron Corporation.

   (c) Tax Withholding.  The Committee shall make appropriate arrangements with
each Participant for the satisfaction of any federal or state tax withholding
required under the Federal Insurance Contributions Act or the Federal
Unemployment Tax Act with respect to a Participant's Retirement Excess Benefit
and with respect to amounts credited to a Participant's PS/SP Excess Benefit
Account.

   (d) No Employment Rights.  Nothing in this Plan shall be deemed to give any
individual a right to remain in the employ of any member of the Affiliated
Group nor affect the right of a member of the Affiliated Group to terminate any
individual's employment at any time and for any reason, which right is hereby
reserved.

   (e) No Assignment of Property Rights.  Except as otherwise provided in
Section 6(a)(iii) with respect to a Participant's indebtedness to any member of
the Affiliated Group, or except as otherwise provided by applicable law, the
interest or property

                                     -10-


rights of any person in the Excess Benefit Plan or in any
distribution to be made hereunder shall not be assigned (either at law or in
equity), alienated, anticipated or subject to attachment, bankruptcy,
garnishment, levy, execution or other legal or equitable process.  Any act in
violation of this Section 6(e) shall be void.  Notwithstanding the foregoing,
the creation, assignment or recognition of a right to all or any portion of a
Participant's Plan Benefit hereunder pursuant to a "qualified domestic
relations order," (within the meaning of section 414(p) of the Code) shall not
constitute a violation of this Section 6(e).

   (f) Effect of Change in Capitalization on PS/SP Excess Benefit Accounts.  In
the event of a stock split, stock dividend or other change in capitalization
affecting Chevron Stock, an appropriate number of Stock Units shall be
substituted for, or added to, each Stock Unit then credited to the PS/SP Excess
Benefit Account of each Participant, and such substituted or added Unit shall
be subject to the same terms and conditions as the original Unit.

   (g) Administration.  The Excess Benefit Plan shall be administered by the
Committee.  No member of the Committee shall become a Participant in the Excess
Benefit Plan.  The Committee shall make such rules, interpretations and compu-
tations as it may deem appropriate.  The Committee shall have sole discretion
to interpret the terms of the Excess Benefit Plan, and any decision of the
Committee with respect to the Excess Benefit Plan, including (without
limitation) any determination of eligibility to participate in the Excess
Benefit Plan and any calculation of Plan Benefits shall be conclusive and
binding on all persons.

   (h) Amendment and Termination.  Chevron Corporation expects to continue the
Excess Benefit Plan indefinitely.  Future conditions, however, cannot be
foreseen, and Chevron Corporation shall have the authority to amend or to
terminate the Excess Benefit Plan at any time and for any reason, by action of
its board of directors or by action of a committee or individual(s) acting
pursuant to a valid delegation of authority.  In the event of the amendment or
termination of the Excess Benefit Plan, a Participant's Retirement Excess
Benefit and PS/SP Excess Benefit shall not be less than the amounts to which he
or she would have been entitled if his or her employment had terminated
immediately prior to such amendment or termination.
