The dollar amount may be adjusted each year by the Internal Revenue Service for cost of living increases in accordance with Internal Revenue Code Sections 414(q) and 415(d)). However, employees who were employed by Ultramar prior to the merger of Ultramar and Diamond Shamrock, Inc. shall not be eligible to participate in this Plan until January 1, 1998. 2. Definitions.

(b) The balance of the Account will be increased or decreased to reflect income, expenses, gains, and losses deemed attributable to the Account.

(a) All rights, title and interest in the balance credited to the Account of a Participant shall remain at all times solely as the Corporation's unsecured contractual obligation under this Plan. Neither a Participant nor any other person, including, without limitation, any Beneficiary shall have any right, title or interest of any kind, by reason of this Plan, in any investment deemed to be made on behalf of a Participant or in any specific assets of the Corporation, the Plan, or any trust other than the Corporation's unsecured and unfunded obligation to make the payment described in this Plan. (b) Notwithstanding the provisions of Section 9(a) hereof, the Corporation may transfer to the trustee of one or more trusts established for the benefit of one or more Participants' assets from which all or a portion of the benefits provided under the Plan will be satisfied, provided that such assets held in trust shall at all times be subject to the claims of general unsecured creditors of the Corporation and no Participant shall at any time have a prior claim to such assets. 10. Annual Distributions. (a) In each year commencing after 1997, a distribution shall be made to all Participants who made Elective Deferrals in the prior year. Such distribution shall be equal to the maximum amount of elective deferrals that the Participant could have deferred to the 401(k) Plan in the prior year and the maximum amount of matching contributions that could have been credited to the Participant's account in the 401(k) Plan in the prior year. Such distribution shall be made to the Participant no later than March 31 of that year. (b) The balance of a Participant's Account shall be appropriately reduced to reflect distributions made hereunder. 11. Payment. (a) Except in the case of the retirement, disability or death of a Participant, a distribution of such Participant's Account balance shall commence as of the earlier of: (i) to the extent practicable, in the sole discretion of the Administrator, the last day a Director Participant is a Director or an Executive Participant is an employee of the Corporation, but not later than the last day of the month following the date a Director Participant ceases to be a Director or an Executive Participant ceases to be an employee of the Corporation; or (ii) any date specified by such Participant on the Notice of Election for distribution of such Participant's Account (which specified date is not after the January 1 following the calendar year in which such Participant reaches age 70). In the case of a distribution by reason of (i) above, such distribution shall be in the form of a lump sum, regardless of the election of the Participant on the Notice of Election. A non- employee Director Participant who continues service with the Corporation after December 3, 1996 shall not be considered to cease to be a Director because of the merger of Diamond Shamrock, Inc. and Ultramar Corporation. (b) In the event of a Participant's retirement or disability, a distribution of such Participant's Account balance shall commence as of the later of: (i) to the extent practicable, in the sole discretion of the Administrator, the last day a Director Participant is a Director or an Executive Participant is an employee of the Corporation, but not later than the last day of the month following the date a Director Participant ceases to be a Director or an Executive Participant ceases to be an employee of the Corporation; or (ii) any date specified by such Participant on the Notice of Election for distribution of such Participant's Account (which specified date is not after the January 1 following the calendar year in which such Participant reaches age 70). In the case of distribution by reason of this Section 11(b), such distribution shall be in the form elected by the Participant on the Notice of Election. A non-employee Director Participant who continues service with the Corporation after December 3, 1996 shall not be considered to cease to be a Director because of the merger of Diamond Shamrock, Inc. and Ultramar Corporation. (c) In the event of a Participant's employment or services as a Director are terminated following a Change in Control, the Participant's Account shall be distributed in a lump sum to the Participant withing sixty (60) days of such termination. (d) In the event of a Participant's death, the balance of the Account shall be distributed in a lump sum to the Beneficiary designated pursuant to Section 12 below. The lump sum payment shall be paid as of the last day of the month following the Participant's date of death. (e) Distributions from the Plan will be made in the form of cash. Distributions will be made to the Participant or, in the event of such Participant's death, to the designated Beneficiary, in accordance with the Participant's election and Section 12 below. (f) On each date for an installment distribution, there shall be distributed to the Participant an amount equal to the sum of the balance then credited to such Participant's Account multiplied by a fraction, the numerator of which is one and the denominator of which is the number of remaining installments. (g) Notwithstanding the provisions of Sections 11(a), (b), (c), (d) and (e) hereof, the person or group designated in clause (i), (ii) or (iii), below, as appropriate, in its absolute discretion exercised in good faith, may accelerate the rate of distribution but only in the case of unanticipated severe financial hardship caused by circumstances over which the Participant has no control, and only to the extent necessary to alleviate such financial hardship. (i) In the case of a Director Participant, an ad hoc committee of the Board consisting of those members of the Compensation Committee of the Board who are not Participants in the Plan. If all the members of the Compensation Committee participate in the Plan, such decision shall be made by the Board; however, no member of the Board shall participate in any such decision affecting uniquely such member as a Participant. (ii) In the case of an Executive Participant, the Administrator. (iii) Notwithstanding clause (i) or (ii), above, if one or more trusts have been established pursuant to Section 9 (b) hereof, to the extent assets in such trust or trusts are available therefor, the trustee of the trust. (h) The balance of a Participant's Account shall be appropriately reduced in accordance with this Section 11 to reflect distributions made hereunder. (i) Any election with respect to the distribution of Compensation deferred for a given period pursuant to this Plan shall be irrevocable. (j) The balance of a Participant's Account may be reduced by the amount of any indebtedness of such Participant to the Corporation at the time of distribution. Failure to reduce any payment to a Participant will not constitute waiver of the Corporation's claim for such indebtedness. (k) Notwithstanding the foregoing provisions of this Section 11, the Corporation shall make provision for the withholding of any Federal taxes that may be required to be withheld by the Corporation in connection with the payments due hereunder. 12. Beneficiary Designation. A Participant may designate in writing any person or persons to whom payments are to be made if the Participant dies before receiving payment of all amounts due under this Plan and the proportion or proportions in which distributions are to be made to each such person, using the Notice of Beneficiary Designation, a form of which is attached as Exhibit C, or some other method of designation which provides Beneficiary designation information similar to that in such Notice of Beneficiary Designation. A Participant may designate a Beneficiary other than a spouse only if the spouse consents in writing as witnessed by a notary public. A Beneficiary designation will be effective only after the Notice of Beneficiary Designation or other designation is filed with and accepted by the Administrator while the Participant is alive and, to the extent indicated by the Participant in the Notice of Beneficiary Designation or other designation, will cancel all beneficiary designations signed and filed earlier by such Participant. Any such designation may be terminated or modified from time to time by the Participant. If and to the extent that a Participant fails to designate a Beneficiary or if all of the Beneficiaries of the Participant die before the death of the Participant or before complete payment of all amounts credited to the Participant's Account under this Plan, the remaining unpaid amount shall be paid in one lump sum to the estate of the last to die of the Participant or the Participant's Beneficiaries. 13. Administration of the Plan. (a) Except as provided in Section 11(f), full power and authority to construe, interpret and administer this Plan shall be vested in the Administrator, who may from time to time adopt any rules or regulations the Administrator determines are necessary or appropriate. If there is no Administrator, the power and authority of the Administrator shall rest with Board; however, no member of the Board shall participate in any decision affecting uniquely such member as a Participant. Decisions of the Administrator, the ad hoc committee described in Section 11(f) and the Board made in good faith, shall be final, conclusive and binding upon all parties. (b) In the absence of bad faith or gross neglect of duty, neither the Administrator nor any member of the Benefit Review Committee, Compensation Committee, or Board of Directors shall have any liability to the Corporation or to any other person, firm or corporation arising out of or connected with the administration of this Plan for any decision made respecting this Plan or its administration. (c) The President, Chairman of the Board and Chief Executive Officer of the Corporation shall appoint a Benefit Review Committee consisting of not less than three nor more than five persons, having the administrative responsibilities and discretionary authority described in this Section 13. The Benefit Review committee has full power and authority to construe the Plan and determine all questions of eligibility and interpretation under the Plan, except with respect to non- employee Directors, in which case the Compensation Committee of the Board of Directors has full power and authority to construe the Plan and determine all questions of eligibility and interpretation under the Plan. The determination of the Compensation Committee shall be final and binding, and not subject to Subsection (d), below. (d) The Plan and any claims of all Participants, with the sole exception of non-employee Directors, arising from the Plan or in any way related to the Plan, are subject to and governed by the Ultramar Diamond Shamrock Corporation Dialogue Dispute Resolution Program ("Dialogue"). If a claim has been appealed from the Administrator to the benefit review committee and the claimant desires to appeal the decision of the Benefit Review Committee, such appeal must be conducted solely within the limitations and procedures of Dialogue. 14. Amendment or Discontinuance of Plan. At the sole discretion of the Board this Plan may be discontinued or changed at any time. Upon such discontinuance, the vested amounts credited to the Account of any Participant shall be distributed in satisfaction of the obligations of the Corporation under this Plan, in the manner selected at the option of the Board or at the option of the Administrator if so directed by the Board, as follows: (a) The Account balance may be distributed in a lump sum as of the date of discontinuance in a manner consistent with Section 11 hereof. The lump sum payment shall be made on the last day of the month following the date of discontinuance; or (b) The Account balance may be distributed in accordance with the Notice of Election; or (c) Commencing on the last day of the month following the date of discontinuance, the Account balance may be distributed in no more than ten annual installments, calculated in the same manner as payments under Section 11(e). Notwithstanding the foregoing provisions of this Section 14, the Board may make any change in this Plan that, under all the circumstances, is beneficial and equitable to the Participants and is consistent with the spirit and purposes of this Plan or is required to protect the tax-deferred status of the Plan. However, no member of the Board who is a Participant in the Plan shall participate in any such decision affecting uniquely such member as a Participant. The Plan is intended to provide benefits for "management or highly compensated" employees within the meaning of Sections 201, 301 and 401 of ERISA, and therefore to be exempt from the provisions of Parts 2, 3 and 4 of Title I of ERISA. Accordingly, the Plan shall terminate and no further benefit shall accrue hereunder in the event it is determined by a court of competent jurisdiction or by an opinion of counsel to the Corporation that such balance of the Plan constitutes an employee pension benefit plan within the meaning of Section 3(2) of ERISA, which is not so exempt. In addition, in the absolute discretion of the Board, the vested benefit of each Participant accrued under such balance of the Plan on the date of termination shall be paid immediately to such Participant in a lump sum. Alternatively, the Plan shall refund Elective Deferrals and earnings in a lump sum if legislative changes require refunds to protect the tax-deferred status of the Plan. 15. Miscellaneous. (a) Except insofar as permitted by applicable law, no sale, transfer, alienation, assignment, pledge, collateralization or attachment of any benefits under the Plan shall be valid or recognized by the Corporation. The Participant, his spouse and his designated Beneficiary shall not have any power to hypothecate, mortgage, commute, modify or otherwise encumber in advance of any of the benefits payable hereunder, nor shall any of said benefits be subject to seizure for the payment of any debts, judgements, alimony, maintenance owed by the Participant or his or her Beneficiary, or be transferable by operation of law in the event of bankruptcy, insolvency, or otherwise. Notwithstanding the foregoing, the Corporation may, if the Committee so determines in its sole discretion, follow the terms of any court order issued in connection with any domestic relations proceeding including but not limited to marital dissolution or child support. (b) The Plan shall be binding upon the Corporation, its assigns, and any successor company which shall succeed to substantially all of its assets and business through merger, acquisition or consolidation, and upon a Participant, his Beneficiary, assigns, heirs, executors and administrators. (c) The terms and conditions of the Plan shall not be deemed to constitute a contract or employment between the Corporation and a Participant. Nothing in this Plan shall of itself be deemed to give a Participant the right to be retained in the service of the Corporation or to interfere with any right of the Corporation to discipline or discharge the Participant at any time. (d) A Participant shall cooperate by furnishing any and all information reasonably requested by the Corporation, the Board or the Administrator, and take such other actions as may be requested in order to facilitate the administration of the Plan and the payment of benefits hereunder. (e) In case any provision of this Plan shall be found illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but the Plan shall be construed and enforced as if such illegal and invalid provision had never been included herein. (f) Any Notice which shall be or may be given under the Plan shall be in writing and shall be mailed by United States mail, postage prepaid. If Notice is to be given to the Corporation (or the Board or the Administrator), such Notice shall be addressed to the Corporation at P.O. Box 696000, San Antonio, Texas 78269-6000, Attention: Vice President, Human Resources; if Notice to a Participant, addressed to the last known address on the Corporation's personnel records. Any Notice or filing required or permitted to be given to a Participant under this Plan shall be sufficient if in writing and hand-delivered, or sent by mail, to the last known address of the Participant. Any party may, from time to time, change the address to which notices shall be mailed by giving written Notice of such new address. (g) The interest in the benefits hereunder of a spouse of a Participant who has predeceased the Participant shall automatically pass to the Participant and shall not be transferable by such spouse in any manner, including but not limited to such spouse's will, nor shall such interest pass under the laws of intestate succession. (h) The benefits provided for a Participant and Participant's Beneficiary under the Plan are in addition to any other benefits available to such Participant under any other plan or program for employees of the Corporation. The Plan shall supplement and shall not supersede, modify or amend any other such plan or program except as may otherwise be expressly provided herein. (i) The payment of benefits under the Plan to a Participant or Beneficiary shall fully and completely discharge the Corporation and the Board from all further obligations under this Plan with respect to the portion of the benefits so paid. (j) If any action at law or in equity is necessary by a Participant or Beneficiary to enforce the terms of the Plan, the Participant or Beneficiary shall be entitled to recover reasonable attorney's fees, costs and necessary disbursements in addition to any other relief to which that party may be entitled. (k) (i) Unless the context clearly indicates otherwise, (A) masculine pronouns shall include the feminine and singular words shall include the plural and vice versa; (B) any reference to a section of the Code or ERISA, any regulation promulgated under the Code or ERISA or any plan (except this Plan) shall refer also to any successor provision to such section, and (C) any reference to a plan shall refer also to such plan as amended from time to time. (ii) Titles and headings of the articles and sections of the Plan are included for ease of reference only and are not to be used for the purpose of construing any portion or provision of the Plan document. (l) This instrument and any Notice may be executed in one or more counterparts, each of which is legally binding and enforceable. (m) Except to the extent other instruments are incorporated herein by reference or there are amendments made to this Plan in the manner specified by Article 13 hereof, this instrument constitutes the entire Plan. 16.
