                                       3

<PAGE>

modified from time to time by resolution of the Board. The Employee Awards shall
be granted to a sufficient and diverse number of Employees to qualify the Plan
as "broad-based" under the governing rules or requirements of the New York Stock
Exchange. The number of shares of EDS Stock that are the subject of Employee
Awards under this Plan that are forfeited or terminated, that expire
unexercised, or that are settled in a manner such that all or some of the shares
covered by an Employee Award are not issued to a Participant, shall be available
for future Employee Awards or Subsequent Grants hereunder. The Committee may
from time to time adopt and observe such procedures concerning the counting of
shares against the Plan maximum as it may deem appropriate. The Board and the
appropriate officers of EDS shall from time to time take whatever actions are
necessary to file any required documents with governmental authorities, stock
exchanges and transaction reporting systems to ensure that shares of EDS Stock
are available for issuance pursuant to Employee Awards.

          6.  Employee Awards.   The Committee shall determine the number of
              ---------------
Employee Awards to be made under this Plan and subject to the provisions of
Paragraph 4 and Paragraph 5 shall designate from time to time the Employees who
are to be the recipients of such Employee Awards either as part of the initial
grant or a Subsequent Grant under the Plan.  Each Employee Award may be embodied
in an Employee Award Statement, which shall contain such terms, conditions and
limitations as shall be determined by the Committee in its sole discretion.
Employee Awards may only be in the form of a non-qualified stock option.
Employee Awards may also be made in combination or in tandem with, in
replacement of, or as alternatives to, grants or rights under this Plan or any
other employee plan of EDS, any of its subsidiaries, or a Participating Employer
including the plan of any acquired entity. No Employee Award may be issued in
exchange for the cancellation of an Employee Award with a lower exercise price.
Notwithstanding anything to the contrary herein, Employee Awards  granted to
Eligible Employees in certain jurisdictions outside of the United States will be
made subject to terms and conditions specified on addenda attached hereto and
incorporated for all purposes.

          (a) Exercise Price of Employee Awards.  The price at which shares of
              ---------------------------------
     EDS Stock may be purchased upon the exercise of an Employee Award shall be
     not less than, but may exceed, the Fair Market Value of the EDS Stock on
     the Grant Date.  Subject to the foregoing provisions, the terms, conditions
     and limitations applicable to any Employee Awards awarded pursuant to this
     Plan, including the terms of any Employee Awards and the date or dates upon
     which they become exercisable, shall be determined by the Committee.

          (b)  Vesting of Employee Award.
               -------------------------

               (i)  Employee Awards shall fully vest, and the Participant's
          interest in such Employee Award shall be nonforfeitable (subject to
          subparagraphs 6(d)) and exercisable in accordance with Section 7
          hereof if the Participant remains in the continuous employment of a
          Participating Employer until the vesting date established by the
          Committee.

               (ii) If the Participant terminates employment with the
          Participating Employer by reason of Retirement, death, or Disability
          at any time before an

                                       4
<PAGE>

          Employee Award granted hereunder becomes fully vested in accordance
          with subparagraph 6(b)(i) above, then such Employee Award shall fully
          vest on the record date of the Participant's termination of
          employment.

          (c) Lapse of Unvested Employee Award at Termination of Employment.
              -------------------------------------------------------------
     Any Employee Award that is not vested pursuant to subparagraph 6(b), shall
     lapse when the Participant is no longer employed by any Participating
     Employer.

          (d) Lapse of Vested Employee Award.  Employee Awards which became
              ------------------------------
     vested in accordance with Plan paragraph 6(b) shall lapse at the earlier of

               (i)   the second anniversary of the date on which such Employee
          Award is one hundred percent (100%) vested;

               (ii)  the ninetieth day following the date the Participant is no
          longer employed by a Participating Employer by reason other than
          death, Disability or Retirement,

               (iii) the second anniversary of the date of a Participant's
          termination of employment by reason of death, Disability or
          Retirement.

          (e) Terms of Employee Awards in Subsequent Grants.  Employee Awards
              ---------------------------------------------
     granted in Subsequent Grants may have terms and conditions that are
     different from or in addition to the terms and conditions for Employee
     Awards specified in other provisions of this Plan, including but not
     limited to terms and conditions which result in different formulae or
     methods for determining the amount of Employee Awards, different vesting
     schedules or different lapse provisions than those of previous Employee
     Awards.

     7.   Election to Exercise.
          --------------------

          (a) Election.  A vested Employee Award which has not lapsed may be
              --------
     exercised after the Moratorium Period, in whole or in part, by timely
     delivery to the Plan Administrator of such forms as may be designated by
     the Committee, a notice of exercise, and payment of the purchase price.
     Notice of exercise shall be effective on the date received by the Plan
     Administrator.  The notice must state the Participant's election to
     exercise the Employee Award, the number of shares with respect to which the
     election to exercise has been made, the method of payment elected, the
     exact name or names in which such shares will be registered and such other
     information and in such form as may be required by the Plan Administrator.
     Upon a Participant's death, the deceased Participant's Employee Award may
     be exercised by the Participant's Beneficiary, subject to the provisions
     hereof.

          (b) Completion of Necessary Forms.  As a condition precedent to
              -----------------------------
     becoming eligible to exercise any Employee Award, the Participant shall be
     required to properly and timely complete, execute and deliver such forms as
     may be designated by the Plan Administrator.  Failure to properly complete,
     execute and deliver such forms before the

                                       5
<PAGE>

     time restrictions set forth in subparagraph 6(d) hereof shall result in the
     lapse of such vested Employee Awards.

          (c) Payment.  The full exercise price for the shares of EDS Stock
              -------
     purchased on the exercise of an Employee Award (i.e., the number of shares
     purchased, multiplied by the Grant Price) may be paid in cash, or, at the
     request of the Participant, and to the extent permitted by applicable law,
     the Committee may approve, in its sole and absolute discretion, cashless
     exercise through a simultaneous sale arranged with a broker of shares of
     EDS Stock acquired on exercise, as permitted under Regulation T of the
     Federal Reserve Board.

          (d) Right to Recovery.  The Plan Administrator or its agent may, in
              -----------------
     any legal method available, seek recovery from any Participant who receives
     an overpayment or exercises an Employee Award which has lapsed or is
     inconsistent with the  provisions of the Plan.

     8.   Administration.
          --------------

          (a) This Plan shall be administered by the EDS Benefits Oversight
     Committee (or its delegate pursuant to paragraph 9 hereof).  The EDS
     Benefits Oversight Committee shall have the power, in its sole and absolute
     discretion, to contract with a third-party administrator to administer this
     Plan.

          (b) Subject to the provisions hereof, the EDS Benefits Oversight
     Committee shall have full and exclusive power and authority to administer
     this Plan and to take all actions which are specifically contemplated
     hereby or are necessary or appropriate in connection with the
     administration hereof.  The EDS Benefits Oversight Committee shall also
     have full and exclusive power to interpret this Plan, to devise necessary
     forms and documents, and to adopt such rules, regulations and guidelines
     for carrying out this Plan as it may deem necessary or proper, all of which
     powers shall be exercised in the best interests of EDS and in keeping with
     the objectives of this Plan.  The EDS Benefits Oversight Committee may, in
     its sole and absolute discretion, amend or modify an Employee Award in any
     manner that is consistent with the purpose and objectives of this Plan and
     is either (i) not adverse to the Participant to whom such Employee Award
     was granted, (ii) required to comply with governing law, or (iii) consented
     to by such Participant.  The EDS Benefits Oversight Committee may correct
     any defect or supply any omission or reconcile any error or inconsistency
     in this Plan or in any Employee Award Statement in the manner and to the
     extent the EDS Benefits Oversight Committee deems necessary or desirable to
     carry it into effect.  Any decision of the EDS Benefits Oversight Committee
     in the interpretation and administration of this Plan shall lie within its
     sole and absolute discretion and shall be final, conclusive and binding on
     all parties concerned.  The Board, Committee or EDS Benefits Oversight
     Committee need not be uniform and consistent in making determinations and
     interpretations in the administration of the Plan.

                                       6

<PAGE>

          (c) No member of the Committee, the EDS Benefits Oversight Committee,
     or any officer or Employee of EDS or Participating Employer to whom the
     Committee has delegated authority in accordance with the provisions of
     paragraph 9 hereof, shall be liable for anything done or omitted to be done
     by such person, by any member of the Committee, or by any officer or
     Employee of EDS or Participating Employer in connection with the
     performance of any duties under this Plan, except for such person's own
     willful misconduct or as expressly provided by statute.  Nothing herein
     shall exculpate any third-party administrator from any contracted liability
     or responsibility to EDS, the Participating Employer, the Plan, its
     participants or beneficiaries thereof or any officials.

  9.   Delegation of Authority.  The Committee may delegate to such
       -----------------------
subcommittees, officers, other Employees of EDS or Participating Employer, or
qualified third-party administrators, its duties under this Plan pursuant to
such conditions or limitations as the Committee may establish.  The Committee
shall have the power and authority to appoint, remove or replace the members of
any such subcommittee, or any officer, Employee or third-party administrator
that has been delegated responsibilities and authority by the Committee.

  10.  Tax Withholding.  Upon the exercise of the Employee Award, or any part
       ---------------
thereof, the Participant may incur certain liabilities for taxes and the
Participating Employer may be required by law to withhold such taxes for payment
to taxing authorities.  Upon determination by the Participating Employer of the
amount of taxes required to be withheld, including taxes, if any, which may be
required to be withheld prior to exercise with respect to the shares to be
issued pursuant to the exercise of the Employee Award, the Plan Administrator
shall establish procedures which allows the Participant (a) to direct the
Participating Employer to withhold from the EDS Stock available for exercise the
number of shares necessary to satisfy the withholding obligations, based on the
market price of the EDS Stock on the date of exercise; (b) to deliver sufficient
cash to the Participating Employer to satisfy its withholding obligations; or,
(c) some combination thereof.  Authorization of the Participant to the
Participating Employer to withhold taxes must be in a form and content
acceptable to the Plan Administrator.  Failure by the Participant to comply with
the foregoing shall entitle the Plan Administrator, in its sole and absolute
discretion, to authorize the sale of a sufficient number of the shares of EDS
Stock which the Participant is entitled to receive upon the exercise of the
Participant's Employee Award in order to satisfy such withholding requirements;
provided however, that neither the Participating Company nor the EDS Benefits
Oversight Committee shall be liable for determining the exact amount of such
taxes, for selling shares of EDS Stock in excess of that required to satisfy
such tax obligation, or for obtaining the highest sales price for any such
shares.  The payment or authorization to withhold taxes by the Participant shall
be completed prior to the delivery of any EDS Stock pursuant to this Plan.  An
authorization to withhold taxes pursuant to this provision will be irrevocable
unless and until the tax liability of the Participant has been fully paid.  Any
income or compensation arising out of the grant, vesting or exercise of an
Employee Award shall not be taken into account in determining overtime, bonus,
life insurance, pension or such other benefits except as provided in the
relevant plan or policy covering such compensation or benefits or as otherwise
required by law.

                                       7
<PAGE>

  11.  Delivery of Shares.  Subject to this paragraph 11 and paragraph 16
       ------------------
hereof, and upon written request of the Participant, the Participating Employer
shall cause certificates for those shares of EDS Stock which the Participant is
entitled to receive upon the exercise of an Employee Award to be delivered to
Participant.  EDS Stock delivered to Participants shall be in treasury shares
unless otherwise specified herein.  No shares of EDS Stock shall be delivered to
the Participant upon the exercise of the Employee Award until (a) the purchase
price, including any applicable fees or commissions, have been paid in full in
the manner herein provided; (b) all the applicable taxes required to be withheld
have been paid or withheld in full; and (c) the approval of any governmental
authority required in connection with the Employee Award or the issuance of
shares thereunder has been received by EDS.  A Participant shall not have any
rights as a shareholder of EDS Stock from this Plan until such EDS Stock is
delivered to the Participant in accordance with the terms of this Plan.

  12.  Amendment, Modification, Suspension or Termination.  EDS may amend,
       --------------------------------------------------
modify, suspend or terminate this Plan for the purpose of meeting or addressing
any changes in legal requirements or for any other purpose permitted by law,
except that (a) no amendment or alteration that would adversely affect the
rights of any Participant under any Employee Award previously granted to such
Participant shall be made without the consent of such Participant and (b) no
amendment or alteration shall be effective prior to approval by the stockholders
of EDS to the extent stockholder approval is required by applicable legal
requirements. Any amendment, modification or suspension may be made through an
addendum, attachment or other ancillary document authorized by the Committee
which shall be incorporated herein for all purposes.  EDS may, in its sole and
absolute discretion, terminate this Plan at any time, provided that such
termination shall not cause any Participant to lose any rights to any vested
Employee Award.

  13.  Assignability.  No Employee Award nor any other benefit under this Plan
       -------------
shall be assignable or otherwise transferable except by a testamentary transfer
or the laws of descent and distribution, or by designation of a beneficiary as
provided in paragraph 15 hereof.  The Committee may prescribe and include in
applicable Employee Award Statements other restrictions on transfer.  Any
attempted assignment of an Employee Award or any other benefit under this Plan
in violation of this paragraph 13 shall be null and void.

  14.  Adjustments.
       -----------

       (a) The existence of outstanding Employee Awards shall not affect in
     any manner the right or power of EDS or its stockholders to make or
     authorize any or all adjustments, recapitalizations, reorganizations or
     other changes in the capital stock of EDS or its business or any merger or
     consolidation of EDS, or any issue of bonds, debentures, preferred or prior
     preference stock (whether or not such issue is prior to, on a parity with
     or junior to the EDS Stock) or the dissolution or liquidation of EDS or a
     subsidiary, or any sale or transfer of all or any part of its assets or
     business, or any other corporate act or proceeding of any kind, whether or
     not of a character similar to that of the acts or proceedings enumerated
     above.

       (b) In the event of any subdivision or consolidation of outstanding
     shares of EDS Stock, declaration of a dividend payable in shares of EDS
     Stock, or other stock

                                       8
<PAGE>

     split, then (i) the number of shares of EDS Stock reserved under this Plan,
     (ii) the number of shares of EDS Stock covered by outstanding Employee
     Awards, (iii) the exercise or other price in respect of such Employee
     Awards, and (iv) the appropriate Fair Market Value and other price
     determinations for such Employee Awards, shall be proportionately adjusted
     by the Committee to reflect such transaction. In the event of any other
     recapitalization or capital reorganization of EDS, any consolidation or
     merger of EDS with another corporation or entity, the adoption by EDS of
     any plan of exchange affecting the EDS Stock or any distribution to holders
     of EDS Stock of securities or property (other than normal cash dividends or
     dividends payable in EDS Stock), then (i) the number of shares of EDS Stock
     covered by Employee Awards in the form of options on EDS Stock, (ii) the
     exercise or other price in respect of such Employee Awards, and (iii) the
     appropriate Fair Market Value and other price determinations for such
     Employee Awards, shall be proportionately adjusted by the Committee to
     reflect such transaction; provided that such adjustments shall only be such
     as are necessary to maintain the proportionate interest of the holders of
     the Employee Awards and preserve, without exceeding, the value of such
     Employee Awards. In the event of a corporate merger, consolidation,
     acquisition of property or stock, separation, reorganization or
     liquidation, the Committee shall be authorized to issue or assume Employee
     Awards by means of substitution of new Employee Awards, as appropriate, for
     previously issued Employee Awards or an assumption of previously issued
     Employee Awards as part of such adjustment.

     15.  Beneficiary Designation.  Beneficiaries shall be designated in such
          -----------------------
manner and according to such requirements as may be designated by the Plan
Administrator.  The designation of a Beneficiary shall be effective on the date
received by the Plan Administrator.  Upon the death of a Participant, a
designated Beneficiary shall be entitled to exercise a vested Employee Award
pursuant to the provisions of paragraph 7 hereof.

     16.  Restrictions.  No EDS Stock or other form of payment shall be issued
          ------------
with respect to any Employee Award unless the Participating Employer shall be
satisfied based on the advice of its counsel that such issuance will be in
compliance with applicable laws, rules or regulations.  Certificates evidencing
shares of EDS Stock certificates delivered under this Plan (to the extent that
such shares are so evidenced) may be subject to such stop transfer orders and
other restrictions as the Committee may deem advisable in order to satisfy the
rules, regulations, agreements or other requirements of the U.S. Securities and
Exchange Commission, or any securities exchange or transaction reporting system
upon which the EDS Stock is then listed or to which it is admitted for
quotation, and any applicable securities law.  The Committee may cause a legend
or legends to be placed upon such certificates (if any) to make appropriate
reference to such restrictions.

     17.  Unfunded Plan.  This Plan shall be unfunded.  Although bookkeeping
          -------------
accounts may be established with respect to Participants who are entitled to EDS
Stock or rights thereto under this Plan, any such accounts shall be used merely
as a bookkeeping convenience.  EDS shall not be required to segregate any assets
that may at any time be represented by EDS Stock or rights thereto, nor shall
this Plan be construed as providing for such segregation, nor shall EDS, the
Board or the Committee be deemed to be a trustee of any EDS Stock or rights
thereto to be

                                       9

<PAGE>

granted under this Plan. Any liability or obligation of EDS to any Participant
with respect to rights granted under this Plan shall be based solely upon any
contractual obligations that may be created by this Plan and any Employee Award
Statement, and no such liability or obligation of EDS shall be deemed to be
secured by any pledge or other encumbrance on any property of EDS. Neither EDS,
any subsidiary, the Board nor the Committee shall be required to give any
security or bond for the performance of any obligation that may be created by
this Plan.

  18.  Governing Law.  This Plan and all determinations made and actions taken
       -------------
pursuant hereto, to the extent not otherwise governed by mandatory provisions of
the Code or the securities laws of the United States, shall be governed by and
construed in accordance with the laws of the State of Texas without regard to
any conflicts of law principles that would compel the application of any other
law.

  19.  No Right to Employment.  Nothing in this Plan or in any Employee Award
       ----------------------
Statement issued pursuant to this Plan shall confer upon any Participant any
right to continue in the employ of the Participating Employer or affect the
Participating Employer's right, subject to applicable law, to terminate the
employment of any Participant at any time, with or without cause.

  20.  No Acquired or Additional Rights.  Grants of  Employee Awards under the
       --------------------------------
Plan are made at the complete discretion of EDS pursuant to the Plan.  The
Committee has complete authority to administer, construe and interpret the Plan,
establish rules and regulations concerning the Plan, amend the Plan, and perform
all other acts deemed reasonable and proper in that regard, including the power
to delegate to others the authority to assist in the administration of the Plan.
No Employee acquires any additional rights as a result of being eligible to
participate in the Plan or deciding to exercise an Employee Award.  There is no
assurance that any future grants will be made under the Plan, or any other plan.
The value of any Employee Award or the proceeds upon the exercise thereof  will
not be reflected in any severance, overtime, benefit, retirement or indemnity
payments that EDS or any affiliate or subsidiary may make to any Participate in
the future.  The offer to participate in the Plan does not constitute an
acquired right. The Employee Award is not considered to be part of employment
compensation and neither eligibility for, nor participation in, the Plan
guarantees any right to future employment with EDS or any Participating
Employer.
