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.

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 - 7 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.

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.
