         1.1  PURPOSE.  The Plan is intended to advance the best interests of
the Company and its stockholders by directly targeting  Company  performance  to
align  with  the ninetieth percentile historical stock-price growth rate for the
Company's  peer  group.   In  addition,  the  Plan  will  provide  the Company's
employees with additional  compensation,  contingent  upon  achievement  of  the
targeted  objectives,  thereby encouraging them to continue in the employ of the
Company or any of its Affiliates.

         1.2  TERM OF PLAN.  The Plan  is  effective  October 1, 1998.  The Plan
shall remain in effect until all Contingent Awards  under  the  Plan  have  been
satisfied or have expired.

                                      I-1

                                   ARTICLE II

                                  DEFINITIONS

          The  words  and phrases defined in this Article shall have the meaning
set out in these definitions  throughout  the  Plan, unless the context in which
any such word or phrase appears reasonably  requires  a  broader,  narrower,  or
different meaning.

         2.1  "AFFILIATE"  means   any   parent   corporation,   any  subsidiary
corporation and any partnership the majority of which is owned by the Company or
a parent corporation or subsidiary corporation.  The term  "parent  corporation"
means  any  corporation  (other  than  the  Company)  in  an  unbroken  chain of
corporations  ending  with  the  Company  if,  at  the  time  of  the  action or
transaction, each  of  the  corporations  other  than  the  Company  owns  stock
possessing  50 percent or more of the total combined voting power of all classes
of stock in one of the  other  corporations  in the chain.  The term "subsidiary
corporation" means any corporation (other than the Company) in an unbroken chain
of corporations beginning with the Company if, at the  time  of  the  action  or
transaction,  each  of  the  corporations other than the last corporation in the
unbroken chain owns stock possessing  50  percent  or more of the total combined
voting power of all classes of stock in one of the  other  corporations  in  the
chain.

         2.2  "APPLICABLE PERCENTAGE" means the percentage of Basic Compensation
taken  into  account  under  a  Contingent  Award as specified in Section 3.1 or
Appendix A.

Employee's pre-tax elective contributions  under  any cafeteria plan governed by
section 125 of the Code and any plan qualified under section 401(k) of the  Code

income):   bonuses  and  other  incentive  compensation,  pension  or retirement
benefits, reimbursements or other expense allowances, fringe benefits (cash  and
non-cash),  moving expenses, deferred compensation (including amounts paid under
the Plan and amounts includible in  gross  income upon the vesting of restricted
stock and upon the exercise of a stock option or stock appreciation right),  and
welfare benefits (such as severance pay).  For purposes of determining the Basic
Compensation  of an Employee who is nonexempt under the Fair Labor Standards Act
of 1938, Basic Compensation shall be defined  as set forth above except that the
definition of Basic Compensation shall include incentive  bonus  payments  under
the  Company's incentive compensation plans, as they may be determined from time
to time.  Except as provided in the previous sentence, it is intended that Basic
Compensation include only regular hourly  wages or regular monthly, semi-monthly
or bi-weekly salary and not other forms of compensation.

         To determine Basic Compensation for the calculation of  payments  to  a
nonexempt Employee, Basic Compensation shall be the sum of the amounts specified
above paid to the Employee for the months that he was employed by the Company or
its  Affiliates  during  the  Performance  Period, multiplied by a fraction, the
numerator of which is 365 and  the  denominator  of  which is the number of days

                                  ARTICLE III

                GENERAL PROVISIONS RELATING TO CONTINGENT AWARDS

         3.1  GRANTS   OF   CONTINGENT   AWARDS.  Effective   October  1,  1998,
Contingent Awards have been  granted  to  Employees  in amounts specified by the
Board, consistent with the levels set forth on  Appendix  A.  In  addition,  the
Board  has  granted to three executive officers of the Company Contingent Awards
of Phantom Stock as  specified  by  the  Board.   Any  Employee who has not been
granted a Contingent Award by the Board but is an Employee on October  1,  1998,
is  hereby  granted  a Contingent Award of 25 percent of his Basic Compensation.
If a person becomes an  Employee  after  October  1,  1998, he will be granted a
Contingent Award on the date that he becomes  an  Employee.   The  size  of  the
Contingent   Award   will   be  commensurate  with  such  Employee's  employment
classification as specified in Appendix  A.  The  Chief Executive Officer of the
Company has the authority to  determine  Contingent  Awards  of  less  than  100
percent  of  Basic  Compensation  for  newly  hired  employees  and  promotions.
Contingent  Awards  equal  to  or in excess of 100 percent of Basic Compensation
must be approved by the Committee or the Board.

         3.2  ATTAINMENT OF PERFORMANCE  TARGETS.  The  First Performance Target
or Second Performance Target  will  be  treated  as  having  been  attained  for
purposes of the Plan and Contingent Awards thereunder only if the average of the
Fair Market Values of the Stock for any 20 consecutive trading day period during
the Performance Period equals or exceeds  the First Performance Target or Second
Performance Target, as applicable.

         3.3  PAYMENT OF CONTINGENT AWARDS.

          (a)  Grantee Who is Still Employed  at  the  End  of  the  Performance
Period.

          If  a  Grantee  of a Contingent Award is an Employee at the end of the
Performance Period and if he has been an  Employee for at least 365 days on such
date, the Company will pay or cause to be paid to him  on  the  Payout  Date  an
amount  equal  to  the Applicable Percentage of his Basic Compensation as of the
date the Second Performance Target is achieved,  or 25 percent of that amount if
the First Performance Target is achieved but the Second  Performance  Target  is
not  achieved.   However, in either case, the amount payable to a Grantee who is
hired by the Company or an Affiliate  after  October 1, 1998, will be reduced so
that he receives a Pro  Rata  Share  of  the  applicable amount specified in the
preceding sentence.

          (b)  Grantee Who is Not Employed at the End of the Performance Period.

          If a Grantee of a Contingent Award has been an Employee for  at  least
365 days, but he is not an Employee at the end of the Performance Period because
of  his  death,  Retirement,  or Disability that occurred during the Performance
Period, the Company

                                     III-1

will pay or cause to be paid to him or his estate on the Payout Date  an  amount
equal  to the Pro Rata Share of the amount that he would have received under the
Contingent Award on such date (as  specified  in  paragraph (a) above) if he had
continued working until the end of the Performance Period and been paid  through
that date his same Basic Compensation that was in effect upon his termination of
employment,  provided  that  for purposes of determining his Pro Rata Share, the
Grantee shall not be given credit for  the time from the date of his termination
of employment to the end of the Performance Period.  If a Grantee is  terminated
without cause during the Performance Period, the Grantee shall be entitled to an
amount  equal  to  the  Pro Rata Share of the amount that he would have received
under the Contingent Award on the Pay-Out Date if he continued working until the
end of the Performance Period  and  been  paid  through that date his same Basic
Compensation that was in effect upon his  termination  of  employment,  provided
that  for  purposes  of determining his Pro Rata Share, the Grantee shall not be
given credit for the time from the  date of his termination of employment to the
end  of  the  Performance  Period.   For  purposes  of  this   Section   3.3(b),
"termination  without  cause"  shall mean termination of Grantee's employment by
the Company other than a termination  based  on the Grantee's failure to perform
the duties required of the Grantee, the Grantee's acting in a manner adverse  to
or  inconsistent  with  the interest of the Company, or the Grantee's taking any
action or being involved in any  activity that adversely affects the interest of
the Company or the ability of the Grantee to perform the duties required of him.
If a Grantee of a Contingent Award  is  not  an  Employee  at  the  end  of  the
Performance  Period for any reason other than his death, Disability, Retirement,
or termination without cause, no amount  will be paid under his Contingent Award
on the Payout Date.

          (c)  Special Rule For  Certain  Grantees  of  Contingent Awards in the
               Event of a Change of Control.

          Notwithstanding any other provision of the Plan, if the Grantee  of  a
Contingent Award whose Applicable Percentage is 400 or more has been an Employee
for  at  least 365 days on the day before a Change of Control that occurs during
the Performance Period, the Company shall pay or cause to be paid to the Grantee
on the earlier of the Payout Date  or 30 days after termination of employment by
the Company, other  than  a  termination  "with  cause",  or  30  days  after  a
termination  of employment by the Employee for "good reason", an amount equal to
the Applicable Percentage of  the  greater  of his Basic Compensation determined
either as of the day before the Change of Control or the date of termination  of
employment,  irrespective  of  whether either of the First Performance Target or
the Second Performance Target  has  been  attained.  For purposes of determining
the amount of any payment upon a Change of Control, the payment shall be subject
to reduction pursuant to Section 3.3(a) in the event the Grantee was hired after
October 1, 1998, but shall not be reduced pursuant to Section 3.3(b) so that for
all purposes of determining the payment, it will be  assumed  that  the  Grantee
remained  an  employee  of  the  Company  or  an  Affiliate  to  the  end of the
Performance Period for purposes hereof;  provided, however, the calculation of a
Pro Rata Share for a Grantee who was hired after October 1, 1998, shall  use  in
the denominator the number of  days  from  October  1,  1998,  to  the  date  of
termination of employment in lieu of the number of days in the

                                     III-2

Performance  Period.  "With cause" shall mean a termination of employment by the
Company solely on account of the  conviction  of,  or plea of nolo contendre by,
the Grantee to the charge of a felony that, through lapse of time or  otherwise,
is  not  subject to appeal, or on account of a material breach of fiduciary duty
to the  Company  through  the  misappropriation  of  Company  funds or property.
Termination by the Grantee for "good reason" shall exist if any of the following
occurs:

          (i)  without   Grantee's   express   written   consent,  the
     assignment  to  Grantee  of  any  duties  inconsistent  with  the
     employment of Grantee immediately prior to the Change of Control,
     or  a  significant  diminution  of  Employee's  position, duties,
     responsibilities  or  status  with   the   Company   from   those
     immediately  prior  to  a  Change  of  Control or a diminution in
     Grantee's titles or offices as  in  effect immediately prior to a
     Change of Control, or any removal of Grantee from, or any failure
     to reelect Grantee to, any of such positions;

          (ii)  a  reduction  by  the  Company  in   Grantee's   Basic
     Compensation in effect immediately prior to a Change of Control;

          (iii)  the  failure by the Company to continue in effect any
     thrift, stock ownership, pension, life insurance, health, dental,
     and  accident   or   disability   plan   in   which  Employee  is
     participating or is eligible to participate at the  time  of  the
     Change of Control (or plans providing Employee with substantially
     similar  benefits),  except as otherwise required by the terms of
     such plans as in effect at  the  time of any Change of Control or
     the taking of any action by  the  Company  that  would  adversely
     affect  Grantee's participation in or materially reduce Grantee's
     benefits under  any  of  such  plans  or  deprive  Grantee of any
     material fringe benefits enjoyed by Grantee at the  time  of  the
     Change  of  Control  or  the  failure  by  the Company to provide
     Grantee with the number of  paid  vacation days to which Employee
     is entitled in accordance  with  the  vacation  policies  of  the
     Company in effect at the time of a Change of Control;

          (iv)  the  failure  by the Company to continue in effect any
     incentive plan or arrangement  in  which Grantee is participating
     at the time of a Change of Control (or to substitute and continue
     other  plans  or  arrangements   providing   the   Grantee   with
     substantially  similar benefits), except as otherwise required by
     the terms of such plans as in  effect  at the time of any  Change
     of Control;

          (v)  the failure by the Company to continue  in  effect  any
     plan  or  arrangement  with  respect to securities of the Company
     (including,  without  limitation,  any  plan  or  arrangement  to
     receive and exercise  stock  options,  stock appreciation rights,
     restricted stock or grants thereof or to acquire stock  or  other
     securities of the Company) in which Grantee is participating

                                III-3

     at the time of a Change of Control (or to substitute and continue
     plans or arrangements providing the  Grantee  with  substantially
     similar  benefits),  except as otherwise required by the terms of
     such plans as in effect at  the  time of any Change of Control or
     the taking of any action by  the  Company  that  would  adversely
     affect  Grantee's participation in or materially reduce Grantee's
     benefits under any such plan;

          (vi)  the relocation of the  Company's  principal  executive
     offices  to  a  location outside the San Antonio, Texas, area, or
     the Company's requiring Grantee  to  be based anywhere other than
     at the location of the  Grantee's  principal  place  of  business
     immediately  prior  to the Change of Control, except for required
     travel on  the  Company's  business  to  an  extent substantially
     consistent with Grantee's business travel  obligations  prior  to
     the  Change  of Control, or, in the event Grantee consents to any
     such relocation, the failure by  the Company to pay (or reimburse
     Grantee for) all reasonable moving expenses incurred  by  Grantee
     relating   to  a  change  of  Grantee's  principal  residence  in
     connection with such relocation  and to indemnify Grantee against
     any loss (defined as the difference between the actual sale price
     of such residence and the fair market value thereof as determined
     by  the  highest  of  three  appraisals  from  Member   Appraisal
     Institute-approved real estate appraisers reasonably satisfactory
     to  both Employee and the Company at the time Grantee's principal
     residence is offered for sale  in connection with any such change
     of residence);

          (vii)  any purported termination of Grantee's employment  by
     the  Company other than termination with cause as defined in this
     Section 3.3(c).

         3.4  PAYMENT OF CONTINGENT AWARDS OF PHANTOM STOCK.  On the Payout Date
the  Company shall pay or cause to be paid to a Grantee of a Contingent Award of
Phantom Stock an amount equal to  the  number of shares of Phantom Stock granted
to him under his Contingent Award multiplied by the Fair Market Value of a share
of Stock on the last day of the Performance Period  if  the  Second  Performance
Target  is  attained and the Grantee is still an Employee on the date the Second
Performance Target is achieved.  If the First Performance Target is attained but
the Second Performance  Target  is  not  attained  and  the  Grantee is still an
Employee at the end of the Performance Period, the Company shall pay or cause to
be paid to the Grantee on the Payout Date one-fourth of the amount specified  in
the preceding sentence.  If during the term of his employment agreement with the
Company  or  an  Affiliate  and  during  the  Performance  Period  the Grantee's
employment with the Company or  an  Affiliate  is  terminated by the Grantee for
"good reason" or by the Company or an Affiliate "without cause" as such  phrases
are  defined  in  the  Grantee's  employment  agreement  with  the Company or an
Affiliate (including as such terms  are  redefined  in  the event of a Change of
Control as defined in such employment agreement), the Grantee shall be  entitled
to  receive within 30 days of such termination an amount equal to his Contingent
Award of Phantom Stock multiplied by the  average of the Fair Market Values of a
share of Stock for the 20 consecutive trading

                                III-4

days  ending on the trading day immediately preceding such termination; provided
that if a Change of Control  shall  have occurred prior to such termination, the
amount shall equal the  greatest  of  his  Contingent  Award  of  Phantom  Stock
multiplied  by  the  highest of the Fair Market Value of a share of Stock on the
trading day immediately preceding  the  Change  of  Control,  or the Fair Market
Value of a share of Stock on the trading day immediately preceding the  date  on
which  the  stock  ceases  to  be  publicly  traded, if such is the case, or the
average of the Fair Market Values  of  a  share  of Stock for the 20 consecutive
trading days ending on the trading day immediately preceding  such  termination.
If  a  Change  of Control shall occur and in connection therewith or at any time
thereafter, the Stock is exchanged for  and converted into anything other than a
publicly traded common stock (excluding cash paid in lieu of fractional shares),
the Grantee shall be entitled to receive, within 30 days  of  such  exchange  or
conversion,  an  amount  equal to the greater of the Contingent Award of Phantom
Stock multiplied by the higher  of  the  Fair  Market  Value of the Stock on the
trading day immediately preceding the Change of  Control,  or  the  Fair  Market
Value  of  the  Stock  on the trading day immediately preceding such exchange or
conversion, in  lieu  of  any  other  payment  or  award  with  respect  to such
Contingent Award.


     If a Grantee of a Phantom Stock Contingent Award is not an Employee at  the
end  of  the  Performance Period because of his death, Retirement, or Disability
that occurs prior to the end of  the Performance Period, the Company will pay or
cause to be paid to him or his estate on the Payout Date an amount equal to  the
Pro  Rata  Share  of the amount that he would have received under the Contingent
Award on that date if he had  continued working until the end of the Performance
Period, provided that for purposes  of  determining  his  Pro  Rata  Share,  the
Grantee  shall not be given credit for the time from the date of his termination
of employment to the end  of  the  Performance  Period.  However, if a Change of
Control has occurred, the amount of the payment shall be determined based  on  a
Pro-Rata  Share  of  an  amount  equal to the greater of his Contingent Award of
Phantom Stock multiplied by the higher of  the Fair Market Value of the Stock on
the trading day immediately preceding the Change of Control, or the Fair  Market
Value  of  the Stock on the last day of the Performance Period, and provided, if
the Stock is converted or  exchanged  for  anything other than a publicly traded
common stock (excluding cash paid in lieu of  fractional  shares),  the  Grantee
shall  be  paid within 30 days of such exchange or conversion in an amount based
on the higher  of  the  Fair  Market  Value  of  the  Stock  on  the trading day
immediately preceding the Change of Control, or the Fair  Market  Value  of  the
Stock  on the trading day immediately preceding such exchange or conversion.  If
a Grantee of a Phantom Stock Contingent  Award  is not an Employee at the end of
the Performance  Period  for  any  reason  other  than  his  death,  Disability,
Retirement,  termination  of  employment  by  the  Grantee for "good reason" (as
defined in his  employment  agreement  with  the  Company  or  an Affiliate), or
termination of employment by the Company or an  Affiliate  "without  cause"  (as
defined in his employment agreement with the Company or an Affiliate), no amount
will be paid under his Contingent Award on the Payout Date.

         3.5  NO  RIGHTS  AS STOCKHOLDER.  No Grantee shall have any rights as a
stockholder as a result of his Contingent Award.

                                     III-5

         3.6  NON-TRANSFERABILITY.  Except as may  be  specified in a "qualified
domestic  relations  order,"  an  unvested  Contingent  Award   shall   not   be
transferable by the Employee otherwise than by will or under the laws of descent
and  distribution.   In the discretion of the Committee, any attempt to transfer
an unvested  Contingent  Award  other  than  under  the  terms  of  the Plan may
terminate the Contingent Award.

         3.7  RECAPITALIZATION OR REORGANIZATION OF THE COMPANY.

          (a)  No Limitations  on  Company's  Rights  to  Effect  Changes.   The
existence of outstanding Contingent Awards shall not affect in any way the right
or  power  of  the  Company  or its stockholders to make or authorize any or all
adjustments,  recapitalizations,  reorganizations,  or   other  changes  in  the
Company's capital structure or its business, or any merger or  consolidation  of
the Company, or any issue of bonds, debentures, or preferred or prior preference
stock  ahead  of  or  affecting  the  Stock or its rights, or the dissolution or
liquidation of the Company, or any sale  or  transfer  of all or any part of its
assets or business, or any other corporate  act  or  proceeding,  whether  of  a
similar character or otherwise.

          (b)  Increase  or  Reduction of Outstanding Shares.  If a stock split,
reverse  stock  split,   stock   dividend,   combination,  recapitalization,  or
reclassification of the Stock, or any other increase or decrease in  the  number
of shares of the Stock outstanding, is effected without receipt of consideration
by  the  Company,  then  the First and Second Performance Targets and Contingent
Awards of Phantom Stock under  the  Plan  shall be appropriately adjusted by the
Committee.  The conversion of any convertible securities of  the  Company  shall
not  be  deemed  to  have been "effected without receipt of consideration by the
Company."  Such adjustment shall be  made  by the Committee, whose determination
in that respe ct shall be final, binding and conclusive.

          (c)  Merger of the Company.   In  the  event  the Company is merged or
consolidated with another entity (whether or not the Company  is  the  surviving
entity) and the Stock is converted into another publicly traded equity security,
then  the  First  and  Second  Performance  Targets and the Contingent Awards of
Phantom Stock under the Plan shall be  adjusted, in good faith, by the Committee
based on the terms of conversion of the  Stock  into  such  equity  security  to
provide  substantially the same economic opportunity and benefits as provided by
the Plan prior to such  merger  or  consolidation.   In the event the Company is
merged or consolidated with another entity, and  the  Stock  is  converted  into
cash,  property,  debt,  or  some  other  consideration  that  is  not an equity
security, each Grantee shall be entitled to  a payment, adjusted as set forth in
the next sentences, at the time of such merger or  consolidation  as  though  he
continued to work until the end of the Performance Period and based on his Basic
Compensation  that  is  in effect at the time of the merger or consolidation.  A
portion of such payment would  be  based  on attainment toward meeting the First
Performance Target and would equal the amount  of  the  payment  that  otherwise
would  have been made if the First Performance Target had been met multiplied by
a fraction the numerator of which shall be the Fair Market Value of the Stock on
the last trading day prior  to  such  merger  or combination minus $12.8125 (the
"Adjusted

                                     III-6

Merger Value") and the denominator of which  shall  be  $22.1875;  provided  the
fraction  shall  not exceed one.  The remaining portion of such payment would be
based on attainment toward meeting the Second Performance Target  and  would  be
equal  to  three-fourths  of the amount of the payment that otherwise would have
been made if the Second Performance Target had been met multiplied by a fraction
the numerator of which shall be the Adjusted Merger Value and the denominator of
which shall be $32.1875; provided  the  fraction  shall  not exceed one.  To the
extent of any conflict between this Subsection (c) and Section 3.3(c)  and  3.4,
Sections 3.3(c) and 3.4 shall control.

          (d)  Spin-off of Business Segment.  In the event the Company  disposes
of  any  business  segment  or  one  or more of its refineries as an entity by a
spin-off dividend of the capital  stock  of  the subsidiary owning such business
segment or refinery, the First Performance Target  and  the  Second  Performance
Target  shall  be  adjusted  for  the  remainder  of  the  Performance Period by
multiplying the First Performance Target and  the Second Performance Target by a
fraction with a numerator equal to the Fair Market Value of  the  stock  at  the
close of business on the first day on which the Stock traded separately from the
stock of the spin-off company (the "Post Spin-off Price") and the denominator of
which  is  the  Fair  Market  Value of the Stock at the close of business on the
immediately preceding trading day (the  "Pre-Spin-Off Price").  In addition, the
Company shall cause the company to be spun-off to  adopt  a  plan  substantially
identical to this Plan provided that the First Performance Target and the Second
Performance  Target  for  such Plan shall be determined by multiplying the First
Performance Target and the Second Performance Target hereunder by a fraction the
numerator of which shall be the Pre-Spin-off Price minus the Post Spin-off Price
and the  denominator  shall  be  the  Pre-Spin-off  Price.   Notwithstanding the
foregoing, the Committee, by an  action  prior  to  the  date  of  the  spin-off
referred to in the previous two sentences, may elect not to adjust the First and
Second  Performance  Targets  and  may  provide  that  the  determination of the
attainment of the First  and  Second  Performance  Targets  shall  be based on a
combination of the Fair Market Value of the Stock and the Fair Market  Value  of
the  common stock of the spun-off company.  Such election by the Committee shall
be evidenced by an amendment  to  the  Plan  identifying the common stock of the
spun-off company and  containing  such  other  provisions  deemed  necessary  or
appropriate  by  the  Committee,  acting  in good faith, to carry out the intent
hereof.

          (e)  Certain Sales  of  Assets.   In  the  event  the  Company sells a
business segment or one or more of its refineries as an  entity,  no  adjustment
shall  be  made to this Plan with respect to Grantees remaining with the Company
or an Affiliate.  However,  with  respect  to  Grantees  who are employed by the
entity acquiring such assets and who  do  not  resign  from  or  terminate  such
employment and are not terminated from such employment for cause for a period of
one  year,  the  Company  shall either continue such Grantees under this Plan or
cause the acquiring  entity  to  assume  the  obligation  hereunder  so that the
transferred Grantee shall receive a Contingent Award hereunder  that  a  Grantee
would have received if a Grantee remained an employee of the Company to the  end
of  the  Performance Period but such Contingent Award shall be based solely upon
the time the

                                     III-7

Grantee  was  an  employee  of the Company or an Affiliate and not upon any time
after the sale of such assets.

                                     III-8

                                   ARTICLE IV

                                 ADMINISTRATION

         The  Plan  shall  be  administered  by the Committee.  All questions of
interpretation and  application  of  the  Plan  and  Contingent  Awards shall be
subject to the determination of the Committee.  A majority of the members of the
Committee shall constitute a quorum.  All determinations of the Committee  shall
be  made by a majority of its members.  Any decision or determination reduced to
writing and signed by a majority of  the  members shall be as effective as if it
had been made by a majority vote at a meeting  properly  called  and  held.   In
carrying  out  its  authority  under the Plan, the Committee shall have full and
final authority and  discretion,  including  but  not  limited  to the following
rights, powers and authorities, to:

         (a)  prescribe, amend, and rescind rules and regulations
    relating to administration of the Plan, and

         (b)  make all other determinations and  take  all  other
    actions  deemed  necessary, appropriate, or advisable for the
    proper administration of the Plan.

The actions of  the  Committee  in  exercising  all  of  the rights, powers, and
authorities under the Plan, when  performed  in  good  faith  and  in  its  sole
judgment, shall be final, conclusive, and binding on all parties.

                                      IV-1

                                   ARTICLE V

                        AMENDMENT OR TERMINATION OF PLAN

         The Board may amend, terminate, or suspend the Plan at any time, in its
sole  and absolute discretion.  However, no amendment or termination of the Plan
may, without  the  consent  of  a  Grantee,  reduce,  terminate,  or suspend the
Grantee's benefits under the Plan  as  in  effect  prior  to  the  amendment  or
termination.

                                      V-1

                                   ARTICLE VI

                                 MISCELLANEOUS

         6.1  UNFUNDED  ARRANGEMENT.  No property shall be set aside nor shall a
trust fund of any kind be established  to secure the rights of any Grantee under
the Plan.  All Grantees shall at all times rely solely upon the  general  credit
of  the  Company  for the payment of any benefit  that becomes payable under the
Plan.

         6.2  NO EMPLOYMENT OBLIGATION.   The  granting  of any Contingent Award
shall not constitute an employment contract, express or implied, nor impose upon
the Company or any Affiliate any obligation to employ or continue to employ  the
Grantee.   The right of the Company or any Affiliate to terminate the employment
of any person shall not be diminished  or  affected by reason of the fact that a
Contingent Award has been granted to him.

         6.3  TAX WITHHOLDING.  The Company or any Affiliate shall  be  entitled
to  deduct  from  the  Contingent  Award  or  other compensation payable to each
Grantee any sums required by  federal,  state,  or  local tax law to be withheld
with respect to payments under a Contingent Award.

         6.4  INDEMNIFICATION OF THE COMMITTEE.   The  Company  shall  indemnify
each  present and future member of the Committee against, and each member of the
Committee shall be entitled without  further  act  on his part to indemnity from
the Company  for,  all  expenses  (including  attorney's  fees,  the  amount  of
judgments,  and  the  amount  of  approved  settlements  made with a view to the
curtailment of costs  of  litigation,  other  than  amounts  paid to the Company
itself) reasonably incurred by him in connection with  or  arising  out  of  any
action,  suit,  or proceeding in which he may be involved by reason of his being
or having been a member of the  Committee,  whether  or not he continues to be a
member of the Committee at the time of  incurring  the  expenses  --  including,
without  limitation,  matters  as  to  which he shall be finally adjudged in any
action, suit, or proceeding to  have  been  found  to have been negligent in the
performance of his duty as a member of the Committee.  However,  this  indemnity
shall  not  include  any  expenses  incurred  by  any member of the Committee in
respect of matters as to which he shall be finally adjudged in any action, suit,
or proceeding to have been guilty  of  gross negligence or willful misconduct in
the performance of his duty as a member of the Committee.  In addition, no right
of indemnification under the Plan shall be available to or  enforceable  by  any
member  of the Committee unless, within 60 days after institution of any action,
suit, or  proceeding,  he  shall  have  offered  the  Company,  in  writing, the
opportunity to handle and defend  same  at  its  own  expense.   This  right  of
indemnification  shall  inure  to  the  benefit  of  the  heirs,  executors,  or
administrators  of  each member of the Committee and shall be in addition to all
other rights to which a member of  the  Committee may be entitled as a matter of
law, contract, or otherwise.

                                      VI-1

         6.5  GENDER AND NUMBER.  If the context requires, words of  one  gender
when used in the Plan shall include the other, and words used in the singular or
plural shall include the other.

         6.6  HEADINGS.   Headings  of  Articles  and  Sections are included for
convenience of reference only and do  not  constitute part of the Plan and shall
not be used in construing the terms of the Plan.

         6.7  ACKNOWLEDGMENT  AND  WAIVER.   The  Committee  or  the  Board  may
require, as a condition to participating in the Plan,  that  an  employee  enter
into  an  Acknowledgment  and  Waiver  in  the  form  deemed  appropriate by the
Committee or the Board  to  establish  that any employment agreement, management
stability agreement or other agreement or arrangement applicable to the employee
will not accelerate, enhance or otherwise change the  benefits  intended  to  be
granted hereunder.

         6.8  OTHER  COMPENSATION PLANS.  Except as provided in Section 6.7, the
adoption of the Plan  shall  not  affect  any  other stock option, incentive, or
other compensation or benefit plans in effect for the Company or any  Affiliate,
nor  shall  the  Plan  preclude the Company from establishing any other forms of
incentive or other compensation for employees of the Company or any Affiliate.

         6.9  GOVERNING LAW.  The  provisions  of  the  Plan shall be construed,
administered, and governed under the laws of the State of Texas.
