     Applicable Period shall be reduced by the amount of such
     prepayment and an amount equal to such prepayment shall be
     applied to reduce the Term Loan Maximum Amounts for each
     subsequent Applicable Period PRO RATA based on the respective
     Marginal Reduction Amounts as in effect immediately prior to such
     reduction; PROVIDED, that if such pro rata

                                 -5- 

     application does not result in compliance by the Company with all
     Required Ratios, then such amount shall be reallocated among such
     subsequent Applicable Periods as the Company shall direct to the
     extent necessary to bring the Company into compliance with the
     Required Ratios.

             (4) In addition, in the event the Company is required
     to make a prepayment of the Term Loans pursuant to
     SECTION 3.2(b)(3), an amount equal to such prepayment shall be

     to occur prior to such particular Applicable Period shall be
     reduced by a like amount.

     outstanding. No voluntary reduction in the Available Amount prior
     to any scheduled reduction in the Available Amount shall affect
     the Available Amount after such scheduled reduction date unless
     such
                                 -6- 

     voluntarily reduced Available Amount is less than the amount
     scheduled to be the Available Amount after such scheduled
     reduction date, in which case the Available Amount after such
     scheduled reduction date shall be no greater than such
     voluntarily reduced Available Amount. The Company shall have the
     right to (y) terminate or reduce the Term Loan Unused Readvance
     Commitment at any time or from time to time or (z) reduce the
     Term Loan Maximum Amount for any particular Applicable Period at
     any time or from time to time; PROVIDED that (1) the Company
     shall give notice of each such termination or reduction to the
     Agent as provided in SECTION 5.5, and (2) the Company may not
     cause the Term Loan Maximum Amount to be less than the aggregate
     principal amount of the Term Loans then outstanding. If the

     the then current Applicable Period and each subsegment Applicable
     Period to occur prior to such particular Applicable Period shall
     be reduced by a like amount. 

         (c) NO REINSTATEMENT. Any reduction in or termination of the
     Commitments pursuant to SECTION 2.2 or any reduction in any Term

     computed for each day and shall be based on the Term Loan Unused
     Readvance Commitment for such day. Accrued Term Loan Commitment

as used in the Credit Agreement and the term "Credit Agreement," as
used in the other Credit Documents or any other instrument, document
or writing furnished to any or all of the Agent, the Co-Agents and the
Banks by the Company shall mean the Credit Agreement as hereby
amended. 

     SECTION 19. EXPENSES; ADDITIONAL INFORMATION. The Company shall
pay to the Agent all reasonable expenses incurred in connection with
the execution of this Amendment. The Company shall furnish to the
Agent, the Co-Agents and the Banks all such other documents, consents
and information relating to the Company or otherwise, as the Agent,
the Co-Agents and the Banks may reasonably require.

     SECTION 20. MISCELLANEOUS. This Amendment (a) shall be binding
upon and inure to the benefit of the Company and the Agent, the
Co-Agents and the Banks and their respective successors, assigns,
receivers and trustees (provided, however, that the Company shall not

of the Banks); (b) may be modified or amended only in accordance with
Section 12.5 of the Credit Agreement; (c) shall be governed by and
construed in accordance with the laws of the State of Texas and the
United States of America; (d) may be executed in several counterparts,
and by the parties hereto on separate counterparts, and each

constitute but one and the same agreement; and (e) together with the
other Credit Documents, embodies the entire agreement and
understanding between the parties

                                 -11-


with respect to the subject matter hereof and of the other Credit
Documents and supersedes all prior agreements, consents and
understandings relating to such subject matter. The headings herein
shall be accorded no significance in interpreting this Amendment.
Wherever the term "including" or a similar term is used in this
Amendment, it shall be read as if it were "including by way of example
only and without in any way limiting the generality of the clause or
concept referred to." Any exhibits, appendices and annexes described
in this Amendment as being attached to it are hereby incorporated into
it.

     SECTION 21. DTPA WAIVER. The Company waives all rights, remedies,
claims, demands and causes of action based upon or related to the
Texas Deceptive Trade Practices-Consumer Protection Act as described
in Sections 17.41 et seq. of the Texas Business & Commerce Code, as
the same pertains or may pertain to this Amendment or any of the
transactions contemplated therein, to the maximum extent that such
rights, etc. may lawfully and effectively be waived. In furtherance of
this waiver, the Company hereby represents and warrants to the Agent,
the Co-Agents and the Banks that (a) the Company is represented by
legal counsel in connection with the negotiation, execution and
delivery of this Amendment, (b) the Company has a choice other than to
enter into this waiver in that it can obtain the Loans from another
institution and (c) the Company does not consider itself to be in a
significantly disparate bargaining position relative to Agent, the
Co-Agents or any of the Banks with respect to this Amendment.

     SECTION 22. RELEASE. The Company hereby releases, discharges and
acquits forever the Agent, the Co-Agents, the Banks and their
respective officers, directors, trustees, agents, employees and
counsel (in each case, past, present or future) from any and all
Claims existing as of the date hereof (or the date of actual execution
hereof by the applicable person or entity, if later). As used herein,
the term "CLAIM" shall mean any and all liabilities, claims, defenses,
demands, actions, causes of action, judgments, deficiencies, interest,
liens, costs and expenses (including court costs, penalties,
attorneys' fees and disbursements, and amounts paid in settlement) of
any kind and character whatsoever, including claims for usury, breach
of contract, breach of commitment, negligent misrepresentation or
failure to act in good faith, in each case whether now known or
unknown, suspected or unsuspected, asserted or unasserted or primary
or contingent, and whether arising out of written documents, unwritten
undertakings, course of conduct, tort, violations of laws or
regulations or otherwise; in each case to the extent, but only to the
extent, such matters relate to this Amendment, the Credit Agreement
and the other Credit Documents and the transactions evidenced and
contemplated hereby and thereby. To the maximum extent permitted by
applicable law, the Company hereby waives all rights, remedies, claims
and defenses based upon or related to SECTIONS 51.003, 51.004 and
51.005 of the Texas Property

                                 -12-
