         other than Cause or the Executive's death, permanent disability (as
         defined in the Company's or STC's Board-approved disability plan or
         policy, as in effect from time to time) or retirement (as defined in
         the Company's or STC's Board-approved retirement plan or policy, as in

         respect of such termination:

<PAGE>   2

                  (i)      the Executive shall be entitled to receive from the
         Company or STC his Accrued Benefits, except that, for this purpose,
         Accrued Benefits shall not include any entitlement to severance under
         any Company or STC severance policy generally applicable to the
         Company's or STC's salaried employees;

                  (ii)     the Executive shall receive from the Company or STC,
         as long as the Executive does not violate the provisions of Paragraph
         6 hereof, severance pay equal to the Executive's then current monthly
         base salary, payable in accordance with the Company's or STC's regular
         pay schedule, for 12 months from the date of termination of
         employment; and

                  (iii)    the Executive shall continue to be covered at the
         expense of the Company or STC by the same or equivalent medical,
         dental, and life insurance coverages as in effect for the Executive
         immediately prior to termination of his employment, until the earlier
         of (A) the expiration of the period for which he receives severance
         pay pursuant to clause (ii) above or (B) the date the Executive has
         commenced new employment and has thereby become eligible for
         comparable benefits, subject to the Executive's rights under COBRA."

         (d)      Section 5(d) of the Employment Agreement hereby amended and
restated in its entirety to read as follows:

                  "(d)     Upon the consummation of a Change of Control during
         the Executive's Employment Period, this Agreement shall automatically
         terminate without the requirement of any notice or any other action on
         the part of any party hereto, and the Executive shall receive, as his
         exclusive right and remedy in respect of such termination (provided
         the Executive continues to abide by his obligations pursuant to this
         Section 5(d)), the same benefits as stated in clauses (i) through
         (iii) of Paragraph 5(c) hereinabove (without duplication); provided,
         however, that the Executive agrees that he shall cooperate fully with
         any effort by the Board to negotiate or enter into a transaction that
         would result in a Change of Control, including, without limitation,
         participating in meetings with prospective investors, acquirors or
         others, including financing sources and legal and other advisors. In
         addition, the Executive agrees that for a period of six months
         following a Change of Control the Executive will make himself
         reasonably available, upon reasonable advance notice, to provide such
         reasonable transitional assistance to the Person acquiring the Company
         or STC and its Subsidiaries as a result of a Change of Control, as the
         Person whose transaction has resulted in a Change of Control shall
         reasonably request."

         3.       Remainder of Employment Agreement Unchanged. Except as
expressly set forth herein, this Amendment shall in no way be construed to
modify any provision of the Employment Agreement.

         4.       Governing Law. The construction and performance of this
Amendment shall be governed by the laws of the State of Texas without giving
effect to the choice of law provisions thereof.

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