     WHEREAS, the board of directors of the Company (the "Board of Directors")

shareholders of the Company that the Company from time to time investigate
strategic alternatives in order to maximize shareholder value; and

     WHEREAS, the Executive is a member of senior management of the Company and
has access to proprietary information pertaining to the business and operations
of the Company; and 

     WHEREAS, the Board of Directors has determined that it is in the best
interests of the Company to provide an incentive to the Executive to remain in
the employ of the Company while the Company is investigating such strategic
alternatives;

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained herein, the Company and Executive agree as follows:

determined according to paragraph 4 below (the "Bonus").  The Bonus will be
payable in full, in cash on the closing date of such Sale of the Company.

     2.   Executive will not be eligible for benefits hereunder if he resigns,
retires, becomes disabled, fails to return from a leave of absence, dies, or is
terminated for cause prior to the close of the Sale of the Company.

     3.   For purposes of this Agreement, a Sale of the Company shall be deemed
to have occurred if the Company disposes of all of its stock or substantially
all of its assets to another party, whether by way of merger, transfer of assets
or otherwise, for cash or securities, in one or a series of transactions.

     ------------------------------------------------------------------------
               $30,000,000 to        $200,000 + ($50,000 x [(Sale Price -
                 $34,999,999              $30,000,000)/$5,000,000])
     ------------------------------------------------------------------------
            $35,000,000 or more                    $250,000
     ------------------------------------------------------------------------

          b.   The Sale Price of the Company, if a stock sale, shall be the

securities all as outstanding on the date of this Agreement and, without
duplication, as thereafter issued or granted.  For the purpose of clause (i) of
the foregoing sentence, all shares shall be deemed to have been acquired if more
than 50% of the Company's outstanding common stock is acquired by a "group" as
that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934.

          c.   For the purposes of calculating the Sale Price of the Company, 
equity securities constituting a part of the consideration referred to in

exchange or quoted on the National Association of Securities Dealers National 
Market System shall be valued at the last closing price thereof prior to the 
date of the consummation or closing of any such Sale of the Company.

          d.   The Sale Price of the Company, if an asset sale, shall be the sum
of (i) the cash (or other consideration) paid by the purchaser for such assets
and (ii) any debt incurred by the purchaser of such assets.

     5.   This Agreement is not and shall not be deemed an employment agreement,
and shall not give the Executive the right to be retained in the employment of
the Company.

     6.   This Agreement shall inure to the benefit of and be binding upon the
parties hereto and their respective heirs, successors, legal representative, and
assigns. 

     7.   Neither this Agreement nor any right or interest hereunder shall be
assignable by the Executive, his beneficiaries or legal representatives.



     8.   If any provision of this Agreement shall be determined to be invalid,
illegal or unenforceable in whole or in part, neither the validity of the
remaining part of such provision nor the validity of any other provision of this
Agreement shall in any way be affected thereby.  In lieu of such invalid,
illegal or unenforceable provision, there shall be added automatically as part
of this Agreement a provision as similar in terms to such invalid, illegal or
unenforceable provision as may be possible and be valid, legal and enforceable.

     9.   This Agreement shall be governed by Texas law.

     10.  This Agreement constitutes the entire agreement of the parties with
respect to the subject matter hereof and supersedes all prior agreements, oral
and written, between the parties hereto with respect to the subject matter
hereof.  This Agreement may be modified or amended only by an instrument in
writing signed by both parties hereto.

     11.  This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together constitute one and
the same instrument.
