     WHEREAS, certain additional parties have subsequently become Guarantors

     WHEREAS, the Company and the Guarantors have requested the Banks and the

valuable consideration and the mutual benefits, covenants and agreements herein
expressed, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto now agree as follows:


     1.   Defined Terms and Overall Changes. All capitalized terms used in this

terms in the Credit Agreement. All defined terms and references in the Credit

be considered Notes under the Credit Agreement for all purposes.

comparable to those currently provided on such page of such Service, as
determined by the Agent from time to time for purposes of providing quotations
of interest rates applicable to dollar deposits in the London interbank market)
at approximately 10:00 a.m., Houston, Texas time, two Business Days prior to the
commencement of such Interest Period, as the rate for dollar deposits with a
maturity comparable to such Interest Period.  In the event that such rate is not
available at such time for any reason, then the "Eurodollar Rate" with respect
to such Eurodollar Rate Advance for such Interest Period shall be the rate at
which dollar deposits of $5,000,000 and for a maturity comparable to such
Interest Period are offered by the principal London office of the Agent in

     of the Company, or of any warrants, rights or options to acquire any such
     shares, now or hereafter outstanding, except to the extent that the
     consideration therefor consists solely of shares of stock (including
     warrants, rights or options relating thereto) of the Company or is approved
     by the Majority Banks; provided, the Company may purchase its stock in a
     maximum, aggregate amount not to exceed $6,000,000.00 in the aggregate."
