Chairman and CEO 
Bellcore

Morristown, NJ 07960


Dear George:

Perot Systems Corporation ("Perot Systems") is pleased to engage you as a
consultant for approximately 20% of your time, in addition to the time that you
will devote as a Board member. As a consultant, you will work on the development
and implementation of the company's business and technology strategies and on
the structure of major business relationships, as well as other projects. We
will work with you to coordinate the timing of your services consistent with
your other business commitments.

We will pay you $12,500 per month for your consulting services and reimburse you
for your reasonable, allocated travel expenses, consistent with Perot Systems'
policies. In addition, we will grant you options to buy 20,000 shares of Perot
Systems common stock at an exercise price of $6.75 per share, with 4,000 of the
options vesting on each of the first five anniversaries of the date of this
letter for as long as this agreement remains in effect, in accordance with the
enclosed Stock Option Agreement and Plan.

You are furnishing services to Perot Systems as an independent contractor. This
letter agreement is not intended to create an employer-employee or agent
relationship between Perot Systems and you. Perot Systems is not responsible for
withholding any amounts for your income tax, Social Security or any other taxes.

If you inform Perot Systems in writing that any consulting services Perot
Systems asks you to perform would conflict with Section 5 of your retirement
agreement as attached to your letter to me dated September 22, 1997, Perot
Systems will immediately withdraw its request.

The term of this agreement will be from November 17, 1997, to November 16, 2002,
provided that either party may terminate this agreement prior to November 16,
2002, at the terminating parties sole discretion, and for any or no reason, on
one month's notice. Upon termination of this agreement you will cease to receive
compensation and the vesting of your options shall cease.




   2


This agreement incorporates by reference the terms of Attachment A
("Confidentiality and Proprietary Rights Agreement") and constitutes the final,
entire, and exclusive agreement between Perot Systems and you with respect to
your consulting for Perot Systems and may only be amended in a writing signed by
both parties.

If you agree to the terms of this agreement, please sign both copies of this
letter and both copies of Attachment A, keep one copy of each for your records,
and return the other copies to Patti Karn, our Stock Administrator, in the
enclosed return envelope. Please also sign the enclosed Stock Option Agreement,
return it to Patti, and she will return a signed copy to you.

Separately you have received and executed a Stock Option Agreement for 30,000
shares vesting over five years as compensation for your service on the Board of
Directors, and the Plan governing that Option Agreement.

We are very excited about the prospect of working with you.

Very truly yours,


/s/ PETER ALTABEF

          alliance partners, and vendors.

     which Consultant can establish (a) he independently developed; (b) is or
     becomes publicly known without a breach of this Agreement by Consultant;

     other non-party without the prior written consent of Perot Systems.

6.   Consultant shall not use Confidential Information for competing with Perot

     jurisdiction of the state and federal courts in Texas. Consultant may not
     assign his rights or obligations under this Agreement. No modification or
     waiver of any provision of this Agreement shall be effective unless in

                          1996 ADVISOR AND CONSULTANT
                  STOCK OPTION/RESTRICTED STOCK INCENTIVE PLAN

                             STOCK OPTION AGREEMENT

THIS AGREEMENT, dated as of, November 17,1997, is by and between Perot Systems
Corporation, a Delaware corporation ("Perot Systems" or the "Company"), and
George H. Heilmeier ("Participant").

                                   WITNESSETH

WHEREAS, Perot Systems has adopted the Perot Systems Corporation 1996 Advisor
and Consultant Stock Option/ Restricted Stock Incentive Plan (the "Plan") to
enable nonemployee advisors of the Company, and consultants under contract with
the Company, to acquire shares of Class A Common Stock, $0.01 par value, of the
Company ("Common Stock") in accordance with the provisions of the Plan; and

WHEREAS, the Committee of the Board of Directors of Perot Systems with
responsibility for administering this Plan (the "Committee") has selected
Participant to participate in the Plan and has determined to grant Participant
the option to purchase shares of Common Stock in accordance with the terms and
conditions of this Agreement, provided, that if any change is made in the shares
of Common Stock (including, but not limited to, by stock dividend, stock split,
or merger or consolidation, but not including the issuance of additional shares
for consideration), the Board of Directors or the Committee will make such
adjustments in the number and kind of shares (which may consist of shares of a
surviving corporation to a merger) and purchase price per share of shares
subject to outstanding options issued under the Plan as the Board of Directors
or the Committee determines are equitable to preserve the respective rights of
the Participants under the Plan;

NOW, THEREFORE, in consideration of the foregoing and of the mutual promises and
other terms and conditions set forth in this Agreement, Perot Systems and
Participant agree as follows:

1.   Award.

     (a) Subject to the terms, conditions, and restrictions set forth in the
     Plan and in this Agreement, Perot Systems hereby awards and grants to
     Participant, and Participant hereby accepts from Perot Systems, the option
     to purchase from Perot Systems the number of shares of Common Stock, at the
     purchase price, and in accordance with the schedule specified on Attachment
     A hereto.


                                     - 1 -
   6

     (b) The option may be exercised only with respect to vested options. Once
     vested, the options may be exercised until the expiration date set forth on
     Exhibit A hereto (unless such right to exercise is earlier terminated
     pursuant to Section 3 hereunder), by delivering written notice of the
     exercise to Perot Systems specifying the number of shares to be purchased
     and paying in full the purchase price for such shares either

         (i) in cash or check in United States dollars or

         (ii) by tendering to Perot Systems shares of the same class as the
         shares being acquired that have been owned by the person exercising the
         option for any period necessary to avoid a charge to Perot Systems'
         earnings and having a fair market value on the date of exercise equal
         to such purchase price, or

         (iii) by a combination of such cash and shares.

     (c) For purposes of this Agreement, the term "fair market value" means,
     with respect to any Purchased Stock means,

(i) if the Purchased Stock is publicly traded, the closing sale price on the
date of determination in the market in which the shares are principally traded
(which may be a stock exchange) or, if no such closing sale price is available
for such date, on the most recent previous date for which such a closing sale
price is available or, if no closing sale price is available, the closing bid
price on such date as quoted in the National Association of Securities Dealers
Automated Quotation ("NASDAQ") system, or by the National Quotation Bureau,
Inc., if not so quoted, or, if no such closing bid price is available for such
date, the closing bid price on the most recent previous date for which such a
closing bid price is available, or

(ii) if Purchased Stock is not publicly traded, their fair market value,
determined by reference to the most recent appraisal of the Common Stock
conducted by appraisers selected by the Board of Directors of Perot Systems.

     (d) For purposes of this Agreement, the term "publicly traded" means
     Purchased Stock has been listed on a registered national securities
     exchange or approved for quotation in the NASDAQ system.

     (e) For purposes of this Agreement, the term "Purchased Stock" means any
     Common Stock or other security purchased upon the exercise of this option,
     together with any successor security, property or cash issued or
     distributed by Perot Systems or any successor entity, whether by way of
     merger, consolidation, share exchange, reorganization, liquidation,
     recapitalization, or otherwise.



                                     - 2 -

2.   Restrictions on Transfer of Option and Purchased Stock.

     (a) The option evidenced by this Agreement may not be sold or otherwise
     transferred, and is exercisable only by Participant.

     (b) Shares of Purchased Stock may not be sold or otherwise transferred for
     six months after stock of the same class as the Purchased Stock is publicly
     traded.

     (c) Perot Systems is not obligated to recognize any purported sale or other
     transfer of the option or Purchased Stock in violation of this Section 2
     and may treat any such purported sale or transfer as null, void, and of no
     effect.

3.   Cessation of Service to Perot Systems.

     Any invested options evidenced by this Agreement will terminate and, except
     to the extent set forth in this Section 3, will cease being exercisable if
     Participant, for any reason whatsoever, is no longer serving Perot Systems
     in at least one of the following capacities: a consultant under contract to
     Perot Systems, or full time employee of Perot Systems (a "Termination
     Event"), unless the Committee, in its sole discretion, agrees in writing
     otherwise. If a Termination Event occurs by reason other than the death of
     Participant, Participant will have sixty days after the Termination Event
     to exercise all vested options hereunder, but in no event later than the
     expiration date set forth on Attachment A hereto. If a Termination Event
     occurs by reason of the death of Participant, Participant's estate will
     have two years after the Termination Event to exercise all vested options
     hereunder, but in no event later than the expiration date set forth on
     Attachment A hereto.

4.   Company's Right of First Refusal.

     (a) Unless and until shares of Purchased Stock are publicly traded, Perot
     Systems will have a right of first refusal to purchase such shares
     purchased hereunder if the holder of the shares desires or is obligated to
     sell or otherwise transfer the shares, but this right will not apply to a
     transfer upon Participant's death by will or by the laws of descent and
     distribution.

     (b) Any holder of such shares who desires or is obligated to sell or
     otherwise transfer them before shares of Purchased Stock are publicly
     traded must give Perot Systems written notice of the proposed sale or other
     transfer. The notice must include the name of the proposed purchaser or
     transferee and describe the circumstances of the transfer. Perot Systems
     may purchase any or all of the shares proposed to be sold or transferred by
     notifying the holder within 30 days of its



                                     - 3 -
   8

     receipt of the notice of its election to exercise its right of first
     refusal and tendering the purchase price of the shares as soon as
     reasonably practicable thereafter.

     (c) The purchase price at which Perot Systems will purchase shares under
     its right of first refusal will be their fair market value, determined by
     reference to the most recent appraisal of the Common Stock conducted by
     appraisers selected by the Board of Directors of Perot on or before the
     date of receipt of the notice of the proposed sale or transfer.

5.   Compliance with Securities Laws.

     (a) Participant acknowledges that the option evidenced by this Agreement
     and the shares to be issued upon exercise of the option have not been
     registered under the Securities Act of 1933, that Perot Systems has no
     present intention to so register them, that such shares may be deemed
     "restricted securities" under Rule 144 of the Act, that the holder of
     restricted securities may be required to hold them for an indefinite period
     of time unless they are registered for sale under the Act or an exemption
     from registration is available, and that routine sales of restricted
     securities under Rule 144 can only be made if Perot Systems meets certain
     requirements, including a requirement to make certain information publicly
     available, and then only in limited amounts and in a specified manner in
     accordance with the terms and conditions of Rule 144.

     (b) Upon demand by Perot Systems, any person exercising the option
     evidenced by this Agreement, at the time of such exercise, will deliver to
     Perot Systems a written representation to the effect that the shares being
     acquired are being acquired for investment and not with a view to any
     resale or distribution thereof.

     (c) Neither Participant nor any successor in interest of Participant will
     sell or otherwise transfer the option evidenced by this Agreement or any
     shares acquired upon exercise of the option in any way that might result in
     a violation of any federal or state securities laws or regulations.

     (d) Perot Systems may require Participant or any subsequent holder of the
     option or of any shares acquired upon exercise of the option to provide
     Perot Systems, before any sale or other transfer, with such
     representations, commitments, and opinions regarding compliance with
     applicable securities laws and regulations as Perot Systems may deem
     necessary or advisable.

6.   Stock Certificates; Rights as Shareholder. Perot Systems will retain for
     safekeeping all certificates representing shares purchased upon exercise of
     the option evidenced by this Agreement. Each such certificate will bear
     such legends as the Board



                                     - 4 -
   9

     determines are necessary or appropriate. Whether or not certificates
     representing such shares have been issued or delivered, Participant will
     have all the rights of a shareholder of Common Stock, including voting,
     dividend and distribution rights, with respect to such shares owned by
     Participant. Participant will not have any rights as a shareholder with
     respect to any shares subject to the option before the date of issuance to
     Participant of shares upon exercise of the option.

7.   Income Tax Withholding. Participant (or any person entitled to act on
     Participant's behalf) shall, upon request by the Company, pay to Perot
     Systems, or Perot Systems may withhold from sums or property otherwise due
     or payable to Participant (or such person), such amount as Perot Systems
     may request for the purpose of satisfying any liability to withhold
     federal, state, local, or foreign income or other taxes. If shares of stock
     are withheld for such purpose, they will be withheld at fair market value,
     as defined in Section 1(c), as of the date of accrual of the liability.

8.   Compliance with Plan. Participant acknowledges receipt of a copy of the
     Plan and further acknowledges that this Agreement is entered into, and the
     option has been awarded, pursuant to the Plan. If the provisions of the
     Plan are inconsistent with the provisions of this Agreement, the provisions
     of the Plan govern and supersede the provisions of this Agreement.

9.   Notices. Any notice to Perot Systems or the Company that is required or
     permitted by this Agreement shall be addressed to the attention of the
     Secretary of Perot Systems at 12377 Merit Drive, Suite 1100, Dallas, Texas
     75251. Any notice to Participant that is required or permitted by this
     Agreement shall be addressed to Participant at the most recent address for
     Participant reflected in the appropriate records of the Company. Either
     party may at any time change its address for notification purposes by
     giving the other written notice of the new address and the date upon which
     it will become effective. Whenever this Agreement requires or permits any
     notice from one party to another, this notice must be in writing to be
     effective and, if mailed, shall be deemed to have been given on the third
     business day after the same is enclosed in an envelope, addressed to the
     party to be notified at the appropriate address, properly stamped, sealed,
     and deposited in the United States mail, and, if mailed to the Company, by
     certified mail, return receipt requested.

10.  Remedies. Perot Systems is entitled, in addition to any other remedies it
     may have at law or in equity, to temporary and permanent injunctive and
     other equitable relief to enforce the provisions of this Agreement. Any
     action to enforce the provisions of, or otherwise relating to, this
     Agreement may be brought in the state or federal courts having jurisdiction
     in Dallas, Dallas County, Texas. By signing



                                     - 5 -
   10

     this Agreement, Participant consents to the personal jurisdiction of such
     courts in any such action.

11.  Assignment. This Agreement shall inure to the benefit of and be binding
     upon the parties hereto and their respective heirs, personal
     representatives and permitted successors and assigns. However, Participant
     does not have the power or right to assign this Agreement without the prior
     written consent of Perot Systems.

12.  Attorneys' Fees. If any action at law or in equity is necessary to enforce
     or interpret the terms of this Agreement, the prevailing party will be
     entitled to reasonable attorneys' fees, costs, and necessary disbursements
     in addition to any other relief to which that party may be entitled.

13.  Severability. If any provision of this Agreement is held invalid or
     unenforceable for any reason, the validity and enforceability of all other
     provisions of this Agreement will not be affected.

14.  Headings. The section headings used herein are for reference and
     convenience only and do not affect the interpretation of this Agreement.

15.  Governing Law. This Agreement shall be governed by and construed in
     accordance with the law of the State of Texas, without regard to that
     state's choice of law rules.

16.  Entire Agreement. This Agreement, together with the Plan and any rules and
     regulations adopted by the Board or Committee thereunder, constitutes the
     entire agreement between the parties with respect to its subject matter.

17.  Amendment. This Agreement may be amended only in a manner that is
     consistent with the Plan and only by a written instrument signed by both
     Perot Systems and Participant.

IN WITNESS WHEREOF, and intending to be legally bound hereby, Participant and a
