Exhibit "A"

                          GENERAL RELEASE OF ALL CLAIMS

This  General  Release of all Claims (this  "Agreement")  is entered into by and
between   _________________   ("Executive")   and  Ultramar   Diamond   Shamrock
Corporation (including its subsidiaries)  (collectively the "Company") effective
as of ______________.

In consideration of the promises set forth in the employment  agreement  between
Executive  and  the  Company,  dated  _________________,  as  amended  as of the
effective date hereof (the "Employment  Agreement),  as well as any promises set
forth in this Agreement, Executive and the Company agree as follows:

(1)      Employment Agreement Entitlements

         The Company will provide  Executive the  post-termination  payments and
         benefits to which he is entitled under the Employment Agreement.

(2)      Return of Property

         All Company files,  access keys, desk keys, ID badges and credit cards,
         and such other  property of the  Company as the Company may  reasonably
         request,  in Executive's  possession must be returned no later than the
         date of  Executive's  termination  from the Company  (the  "Termination
         Date").

(3)      General Release and Waiver of Claims

         Except  as  provided  in the  last  sentence  of  this  paragraph  (3),
         Executive hereby  unconditionally and forever releases,  discharges and
         waives  any and all  claims of any nature  whatsoever,  whether  legal,
         equitable or  otherwise,  which  Executive may have against the Company
         arising at any time on or before the Termination  Date, other than with
         respect to the  obligations  of the Company to the Executive  under the
         Employment  Agreement  and all  Company-sponsored  employee  benefit or
         compensation  arrangement,  including all  qualified  and  nonqualified
         retirement,  stock option or other equity-based compensation,  deferred
         compensation,  bonus,  incentive,  or welfare benefit or other employee
         benefit plan,  policy,  program or arrangement,  in which the Executive
         participated  or was eligible to participate  prior to the  Termination
         Date (collectively referred to as the "Benefit Plans"). This release of
         claims  extends to any and all claims of any nature  whatsoever,  other
         than with respect to the  obligations  of the Company to the  Executive
         under the Employment  Agreement and the Benefit  Plans,  whether known,
         unknown or capable or  incapable  of being known as of the  Termination
         Date of  thereafter.  This  Agreement is a release of all claims of any
         nature whatsoever by the Executive against the Company, other than with
         respect to the  obligations  of the Company to the Executive  under the
         Employment Agreement and the Benefit Plans, and includes, other than as
         herein  provided,  any and  all  claims,  demands,  causes  of  action,
         liabilities whether known or unknown including those caused by, arising
         from or related to Executive's employment relationship with the Company
         including,  but without limitation,  any and all alleged discrimination
         or acts of  discrimination  which  occurred or may have  occurred on or
         before  the  Termination  Date  based upon  race,  color,  sex,  creed,
         national  origin,  age,  disability or any other violation of any equal
         employment  opportunity  law,  ordinance,  rule,  regulation  or order,
         including,  but not  limited to,  Title VII of the Civil  Rights Act of
         1964, as amended;  the Civil Rights Act of 1991; the Age Discrimination
         in  Employment  Act,  as amended  (as  further  described  in Section 7
         below);  the Americans  with  Disabilities  Act; or any other  federal,
         state or local laws, or regulations regarding employment discrimination
         or termination of  employment.  This also includes  claims for wrongful
         discharge,   fraud,  or  misrepresentation  under  any  statute,  rule,
         regulation, or under the common law.

         The  Executive  agrees and  understands  and  knowingly  agrees to this
         release because it is his intent in executing this Agreement to forever
         discharge  the Company  from any and all present,  future,  foreseen or
         unforeseen  causes of action except for the  obligations of the Company
         set forth in the Employment Agreement and the Benefit Plans.

         Notwithstanding the foregoing, Executive does not release, discharge or
         waive any rights to indemnification  that he may have under the By-Laws
         of the Company, the laws of the State of Delaware,  any indemnification
         agreement  between  the  Executive  and the  Company  or any  insurance
         coverage maintained by or an behalf of the Company.

(4)      Release  and  Waiver  of  Claims  Under  the  Age   Discrimination  in
         Employment Act

         Executive  acknowledges that the Company encouraged him to consult with
         an attorney of his choosing,  and through this Agreement encourages him
         to consult with his attorney  respecting  possible claims under the Age
         Discrimination in Employment Act of 1967, as amended ("ADEA"), and that
         Executive  acknowledges  that he understands that the ADEA is a federal
         statute  that  prohibits  discrimination,  on  the  basis  of  age,  in
         employment,  benefits, and benefit plans. Executive wishes to waive any
         and all claims under the ADEA that he may have,  as of the  Termination
         Date, against the Company, its shareholders,  employees,  or successors
         and hereby waives such claims.  Executive  further  understands that by
         signing this  Agreement he is in fact  waiving,  releasing  and forever
         giving up any claim under the ADEA that may have existed on or prior to
         the  Termination  Date.  Executive  acknowledges  that the  Company has
         informed him that he has at his option,  twenty-one  (21) days in which
         to sign  the  waiver  of this  claim  under  ADEA,  and he does  hereby
         knowingly  and  voluntarily  waive  said  twenty-one  (21) day  period.
         Executive  also  understands  that he has seven (7) days  following the
         Termination  Date within which to revoke the release  contained in this
         paragraph  by  providing  a  written  notice of his  revocation  of the
         release  and  waiver  contained  in  this  paragraph  to  the  Company.
         Executive  further  understands  that this right to revoke the  release
         contained in this paragraph relates only to this paragraph and does not
         act as a revocation of any other term of this Agreement.

(5)      Proceedings

         Executive  has not filed,  and agrees  not to  initiate  or cause to be
         initiated on his behalf,  any  complaint,  charge,  claim or proceeding
         against the Company before any local, state or federal agency, court or
         other  body  relating  to  his  employment  or the  termination  of his
         employment  (each  individually,  a  "Proceeding"),  and  agrees not to
         voluntarily  participate in any Proceeding.  Executive waives any right
         he may have to benefit in any manner from any relief (whether  monetary
         or otherwise) arising out of any Proceeding.

(6)      Remedies

         If Executive  initiates or voluntarily  participates in any Proceeding,
         or if he materially fails to abide by any of the material terms of this
         Agreement or his material post-termination obligations contained in the
         Employment  Agreement,  or if he revokes the ADEA release  contained in
         Paragraph 4 at this  Agreement  within the  seven-day  period  provided
         under  Paragraph 4, the Company may, in addition to any other  remedies
         it may have,  reclaim  any  amounts  paid to him under the  termination
         provisions  of the  Employment  Agreement or terminate  any benefits or
         payments  that are  subsequently  due under the  Employment  Agreement,
         without waiving the release granted herein.  Executive acknowledges and
         agrees  that the remedy at law  available  to the Company for breach of
         any of his post-termination  obligations under the Employment Agreement
         or his obligations under Paragraphs 3, 4, and 5 of this Agreement would
         be  inadequate  and that  damages  flowing  from such a breach  may not
         readily  be   susceptible   to  being   measured  in  monetary   terms.
         Accordingly,  Executive  acknowledges,  consents  and agrees  that,  in
         addition to any other rights or remedies  which the Company may have at
         law,  in equity or under this  Agreement,  upon  adequate  proof of his
         violation of any such provision of this Agreement, the Company shall be
         entitled  to  immediate  injunctive  relief and may obtain a  temporary
         order  restraining  any  threatened  or  further  breach,  without  the
         necessity of proof of actual damage.

         Executive  understands  that by entering into this Agreement he will be
         limiting the  availability of certain remedies that he may have against
         the Company and  limiting  also his  ability to pursue  certain  claims
         against the Company.

(7)      Severability Clause

         If any  provision  or part of this  Agreement is found to be invalid or
         unenforceable, only that particular provision or part so found, and not
         the entire agreement, will be inoperative.

(8)      Non-Admission

         Nothing  contained in this  Agreement will be deemed or construed as an
         admission of wrongdoing or liability on the part of the Company.

(9)      Governing Law

         This  Agreement  shall be governed by and construed in accordance  with
         the laws of the State of Delaware, applicable to agreements made and to
         be performed in that state;  and the parties agree to the  jurisdiction
         of the U.S.  District Court for the District of Delaware,  and agree to
         appear in any action in such courts by service of process by  certified
         mail, return receipt requested, at the following addresses:
