              (i)  solicit any current employee, agent or representative to
                   terminate his or her relationship with the Company; or

                   or sources of supply to terminate or adversely change their
                   relationship with the Company.

         (b)  The Company shall have the right, subject to applicable law, to
              inform any other third party that the Company reasonably believes

<PAGE>
 
              contemplating, participating with Employee or receiving from
              Employee assistance in violation of this Agreement, of the terms
              of this Agreement and of the rights of the Company hereunder, and
              that participation by any such third party with Employee in
              activities in violation of this Section 5 may give rise to claims
              by the Company against such third party.

     6.  Confidential Information.  Employee shall not, directly or indirectly,
         ------------------------                                              
reveal, divulge, disclose or otherwise make known to any person, firm or
corporation, any information ("Confidential Information") concerning any matters
affecting or relating to the business of the Company or its affiliates,
including, but not limited to, their manner of operation, any of their
customers, any confidential or proprietary records, customer lists, data, trade
secrets, plans, processes, specifications or opportunities which are the
property of the Company or its affiliates or were learned by Employee in the
course of his relationship with the Company, unless (i) such information has
become publicly available through no act or omission to act on the part of
Employee; (ii) such information was disclosed to Employee by third parties under
no duty of confidentiality to the Company or its affiliates; or (iii) Employee
is required to disclose such Confidential Information by subpoena or under the
order of a court of law. Employee shall give all physical manifestations of
Confidential Information and confidential or proprietary information of the
Company and its affiliates in his control or possession to the Company within
five days after the date hereof.  Employee acknowledges all such items are and
remain the sole property of the Company.

     7.  Payments.  In consideration for the termination of the Employment
Agreement and the covenants of the Employee contained herein, the Company agrees
to continue the current salary (calculated on a monthly basis to be Employee's
annual salary divided by 12) of Employee until April 30, 1999, payable at such
times as the Company regularly pays its executive officers. During such period,
upon reasonable prior notice, Employee shall be available during regular
business hours, except for any accrued vacation unpaid after giving effect to
the payment of the two weeks vacation provided for below (provided Employee will
be available for consultation by telephone during any such period), and shall
use his best reasonable efforts to assist Company management in the affairs and
operations of the Company, including review of periodic reports and filings
relating to periods ending prior to the date hereof. The Company also agrees to
pay Employee a sum equal to $144,510 on or before March 3, 1999 and to pay
Employee an additional $144,510 six (6) months from the date hereof. Any payment
required hereunder shall be subject to deductions for such items as required
under any applicable federal or state law, including without limitation,
federal, state and city withholding tax, Medicare and F.I.C.A. The Company
further agrees to pay to Employee two weeks of his accrued but unused vacation
time, calculated as of April 30, 1999. No payment will be made for any accrued
but unpaid sick days. The Company further agrees to transfer the property listed
on Exhibit A attached hereto to the Employee and to allow Employee to remove
such items from the Company. The Company agrees to treat all payments of
compensation hereunder as consulting fees for tax purposes, to the extent it may
lawfully do so, and it is tax efficient to Employee.

8.  Consulting Services.  During the period commencing May 1, 1999 and  ending
    -------------------

request of, and subject to reasonable notice from, the Company.  Such consulting
services shall be rendered in

payments in Section 7 above, the Company agrees to pay Employee the sum of
$187.50 per hour for each hour such consulting services are rendered.

     9.  Relief.  Employee acknowledges and agrees that damages at law would be
         ------                                                                
insufficient for breach of any of Employee's covenants in Sections 4, 5, and 6
of this Agreement. Accordingly, Employee agrees that in the event of a breach or
threatened breach by Employee any such provisions, the Company shall be entitled
to equitable relief in the form of an injunction to prevent irreparable injury.

     10.  Reformation.  If any provision of this Agreement is held to be
          ----------- 
illegal, invalid or unenforceable under present or future laws effective during
the term hereof, in lieu of such illegal, invalid or unenforceable provision,
there shall be added automatically as a part of this Agreement a provision as
similar in terms to such illegal, invalid or unenforceable provision as may be
possible and be legal, valid and enforceable.

     11.  Further Assurances.  From time to time, upon request, Employee and the
          ------------------                                                    
Company shall, without further consideration, execute, deliver and acknowledge
all such further documents, instruments, releases, motions and orders as the
Company or Employee may reasonably require more effectively to evidence or
effectuate the transactions contemplated herein.

     12.  Waiver.  The failure of any party to insist, in any one or more
          ------
instances, upon performance of any of the terms, covenants or conditions of this
Agreement shall not be construed as a waiver or a relinquishment of any right or
claim granted or arising hereunder or of the future performance of any such
term, covenant, or condition, and such failure shall in no way affect the
validity of this Agreement or the rights and obligations of the parties hereto.

     13.  LAW GOVERNING.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO THE

          ----------
benefit of the parties hereto and their respective representatives, heirs,
executors, successors and permitted assigns. The parties hereto shall not be

however, that the Company shall be permitted to assign its rights under this
Agreement without the prior written consent of Employee in connection with the
sale of all or substantially all of the Company's business (whether by asset
sale, sale of capital stock, merger or otherwise).

     15.  Press Release.  The Company and Employee agree that the press release
          -------------
