                           TWENTY-FIRST AMENDMENT TO
                    NATIONAL CONVENIENCE STORES INCORPORATED
                         PROFIT SHARING PLAN AND TRUST
                            AS AMENDED AND RESTATED

                              W I T N E S S E T H

         National Convenience Stores Incorporated ("Company") and Cullen Center
Bank and Trust ("Trustee") entered into the Profit Sharing Plan and Trust
Agreements, effective July 1, 1968, creating the National Convenience Stores
Incorporated Profit Sharing Plan and Separate Trust Agreement.  The Plan and
Trust have been amended twenty (20) times with the Fourth Amendment

date of the First and Second Amendments being July 1, 1968, the effective date
of the Third and Fourth and Fifth Amendments being July 1, 1976, the effective
date of the Sixth Amendment being July 1, 1977, the effective date of the
Seventh Amendment being July 1, 1978, the effective date of the Eighth and
Ninth Amendments being July 1, 1981, the effective date of the Tenth Amendment
being July 1, 1982, the effective date of the Eleventh Amendment, substituting
Texas Commerce Bank as Trustee, being January 1, 1985, the effective date of
the Twelfth Amendment being January 1, 1985, the effective date of Thirteenth
Amendment being January 1, 1985, the effective date of the Fourteenth Amendment
being July 1, 1985, the effective date of the Fifteenth Amendment being July 1,

effective date of the Twentieth Amendment and Restatement (the "Plan and
Trust") being July 1, 1989.  Article XVI, Section 16.1 of the Plan and Trust
permits the Company to amend the Plan and Trust.  Effective as if the
amendments made below were originally included in the Twentieth Amendment and
Restatement, the Plan and Trust is hereby amended as follows:

                 1.       Section 1.3 is amended by adding at the end thereof
         the following new paragraph:

                          For the purpose of determining the Actual
                 Contribution Percentage of a Highly Compensated Eligible
                 Employee who is either a 5% owner or one of the ten (10)
                 Highly Compensated Eligible Employees paid the greatest amount
                 of compensation (as defined under Code Section 415) during the
                 Plan Year, and is thereby subject to the family aggregation
                 rules of Code Section
   2
                 414(q)(6), the Actual  Contribution Percentage for the
                 family group (which is treated as one Highly Compensated
                 Eligible Employee) is the Actual Contribution Percentage
                 determined by combining the contributions and compensation of
                 all eligible Family Members.  Except to the extent taken into
                 account in the preceding sentence, the contributions and
                 compensation of all Family Members are disregarded in
                 determining the Actual Contribution Percentages for the groups
                 of Highly Compensated Eligible Employees and Non-Highly
                 Eligible Compensated Employees.


                 2.       Section 1.15 is amended by deleting the second to
         last sentence therein and adding the following paragraph at the end
         thereof:

                          In addition to other applicable limitations set forth
                 in the Plan, and notwithstanding any other provision of the
                 Plan to the contrary, for Plan Years beginning on or after
                 January 1, 1994, the annual compensation of each employee
                 taken into account under the Plan shall not exceed the OBRA
                 '93 annual compensation limit.  The OBRA '93 annual
                 compensation limit is $150,000, as adjusted by the
                 Commissioner for increases in the cost of living in accordance
                 with Section 401(a)(17)(B) of the Internal Revenue Code.  The
                 cost-of-living adjustment in effect for a calendar year
                 applies to any period, not exceeding 12 months, over which
                 compensation is determined (determination period) beginning in
                 such calendar year.  If a determination period consists of
                 fewer than 12 months, the OBRA '93 annual compensation limit
                 will be multiplied by a fraction, the numerator of which is
                 the number of months in the determination period, and the
                 denominator of which is 12.

                          For Plan Years beginning on or after January 1, 1994,
                 any reference in this Plan to the limitations under Section
                 401(a)(17) of the Code shall mean the OBRA '93 annual
                 compensation limit set forth in this provision.

                          If compensation for any prior determination period is
                 taken into account in determining an employee's benefits
                 accruing in the current Plan Year, the compensation for that
                 prior determination period is subject to the OBRA '93 annual
                 compensation limit in effect for that prior determination
                 period.  For this purpose, for determination periods beginning
                 before the first day of the first Plan Year beginning on or
                 after January 1, 1994, the OBRA '93 annual compensation limit
                 is $150,000.

                 3.       Section 1.47 is amended by inserting after the term "
         'Trustee' means" the following:

                          Merrill Lynch Trust Company of Texas.

                 4.       Section 3.5 is amended by inserting at the end
         thereof the following paragraph:

                          The amount of Excess Contribution to be
                 recharacterized under Section 3.5(2) above or distributed
                 under 3.5(1) above with respect to a Highly Compensated
                 Eligible Employee for a Plan Year, shall be reduced by any
                 Excess Deferral Contribution previously distributed to such
                 Employee under Section 3.7 below for the taxable year ending
                 with or within the Plan Year.

                 5.       Section 3.6 is amended -

                 a)       by adding after the end of the first sentence therein
                 the following new paragraph, with the second sentence therein
                 to thereafter begin as a new paragraph:

                                  For this purpose, an eligible employee is any
                          employee who is directly or indirectly eligible to
                          receive an allocation of matching contributions or to
                          make employee contributions and includes:  an
                          employee who would be a plan participant but for the
                          failure to make required contributions; an employee
                          whose right to make employee con-tributions or to
                          receive matching contributions has been suspended
                          because of an election (other than certain one-time
                          elections) not to participate; and an employee who
                          cannot make an employee contribution or receive a
                          matching contribution because section 415(c)(1) or
                          section 415(e) prevents the employee from receiving
                          additional annual additions.  In the case of an
                          eligible employee who makes no employee contributions
                          and who receives no matching contributions, the
                          contribution ratio that is to be included in
                          determining the Actual Contribution Percentage is
                          zero.  For a plan year, contributions will be taken
                          into account as follows:  An employee contribution is
                          to be taken into account if it is paid to the trust
                          during the plan year or paid to an agent of the plan
                          and transmitted to the trust within a reasonable
                          period after the end of the plan year.  An excess
                          contribution to a cash or deferred arrangement that
                          is recharacterized (but only if such
                          recharacterization is properly provided for under
                          Section 3.3(2) above) is to be taken into account in
                          the plan year in which the contribution would have
                          been received in cash by the employee had the

                          employee not elected to defer the amounts.  A
                          matching contribution taken into account for a plan
                          year only if it is (1) made on account of the
                          employee's elective or employee contributions for the
                          plan year, (2) allocated to the employee's account as
                          of a date within that year, and (3) paid to the trust
                          by the end of the 12th month following the close of
                          that year.  Qualified matching contributions which
                          are used to meet the requirements of Code Section
                          401(k)(3)(A) are not to be taken into account for
                          purposes of the ACP test of Code Section 401(m).  For
                          purposes of determining whether a plan satisfies the
                          actual contribution percentage test of Code Section
                          401(m), all employee and matching contributions that
                          are made under two or more plans that are aggregated
                          for purposes of Code Section 401(a)(4) and 410(b)
                          (other than section 410(b)(2)(A)(ii)) are to be
                          treated as made under a single plan and that if two
                          or more plans are permissively aggregated for
                          purposes of Code Section 401(m), the aggregated plans
                          must also satisfy Code Section 401(a)(4) and 410(b)
                          as though they were a single plan.

                 b)       by adding at the end thereof the following paragraph:

                                  The distribution (or forfeiture, if
                          applicable) of excess aggregate contributions will
                          include the income allocable thereto.  The income
                          allocable to the excess aggregate contributions
                          includes income for the plan year for which the
                          excess aggregate contributions were made and may
                          include income for the period between the end of the
                          plan year and the date of distribution (or
                          forfeiture).  The manner in which income allocable to
                          excess aggregate contributions is to be calculated
                          shall be made in accordance with Treas.  Reg. Section
                          1.401(m)-1(e)(3)(ii).

                 and,

                 c)       by deleting the last paragraph therein and
                 substituting therefor the following paragraph:

                                  Restriction on Multiple Use of Alternative
                          Limit.  In addition to the limits prescribed by this
                          Section 3.3 and Section 3.8 of this Article III, in
                          the event the limits in those sections have been both
                          satisfied under the 1.25 or (a) portion limit or
                          otherwise in a manner that would violate Section
                          401(m)(9)(A) of the Code, the provisions of Section
                          1.401(m)-2 of the Treasury Regulations shall be
                          applied and complied with in order to satisfy this
                          requirement.  This may result in corrective
                          distributions to certain Highly Compensated Eligible
                          Employees.  Any corrections or other adjustments made
                          to satisfy this requirement shall be determined by
                          the Committee in accordance with the Treasury
                          Regulations.  The corrective distribution shall be
                          first made by reducing the Actual Deferral





                                      -4-
   5
                          Percentage and with respect to all Highly Compensated
                          Eligible Employees.

                 6.       Section 7.10 shall be amended by adding at the end
         thereof the following paragraph:

                          Notwithstanding the preceding provisions of Section
                 7.10(b), in the event of the complete termination of the Plan,
                 amounts of Accounts and benefits under this Plan due to be
                 distributed to missing Participants or Beneficiaries shall be
                 preserved and protected outside the Plan by purchase of an
                 annuity or other acceptable method including the establishment
                 of an individual retirement account or other bank or financial
                 institution interest bearing or fixed income account in the
                 name of or for the benefit of such missing Participant or
                 Beneficiary.

                 7.       Section 9.8 is amended by adding at the end thereof
         the following paragraph:

                          If a distribution is one to which Sections 401(a)(11)
                 and 417 of the Code do not apply, such distribution may
                 commence less than 30 days after the notice required under
                 Section 1.411(a)-11(c) of Treasury Regulations is given,
                 provided that:

                                  (1)      the Committee clearly informs the
                          Participant that the Participant has a right to a
                          period of at least 30 days after receiving the notice
                          to consider the decision of whether or not to elect a
                          distribution (and, if applicable, a particular
                          distribution option), and

                                  (2)      the Participant, after receiving the
                          notice, affirmatively elects a distribution.

                 8.       The Plan and Trust as amended hereby shall be
         continued.

         IN WITNESS WHEREOF, the Company has caused this Twenty-First Amendment
to be executed in its name and on its behalf by the proper officers thereunto
duly authorized this 9th day of August 1994.
