Closing, Borrower and Lender shall have:

     (a)  Executed and delivered this Amendment; and

     (b)  Paid to Lender an amendment fee in the amount of $10,000.

                          ARTICLE III: MISCELLANEOUS

     Section 3.1. Continuing Effect. Except as modified and amended hereby, the
Loan Agreement and other Loan Documents are and shall remain in full force and
effect in accordance with their terms.

     Section 3.2. Payment of Expenses. Borrower agrees to pay to Lender the
reasonable attorneys' fees and expenses of Lender's counsel and other expenses
incurred by Lender in connection with this Amendment.

     Section 3.3. Binding Loan Agreement. This Amendment shall be binding upon,
and shall inure to the benefit of, the parties' respective representatives,
successors and assigns.

     Section 3.4. Ratification. Except as otherwise expressly modified by this
Amendment, all terms and provisions of the Loan Agreement, the Amended Notes and
the other Loan Documents, shall remain unchanged and hereby are ratified and
confirmed and shall be and shall remain in full force and effect, enforceable in
accordance with their terms.

     Section 3.5. No Defenses. Borrower by its execution of this Amendment,
hereby declares that it has no set-offs, counterclaims, defenses or other causes
of action against Lender arising out of the Loans, the modification of the
Loans, any documents mentioned herein or otherwise; and, to the extent any such
setoffs, counterclaims, defenses or other causes of action may exist, whether
known or unknown, such items are hereby waived by Borrower.

     Section 3.6. Further Assurances. The parties hereto shall execute such
other documents as may be necessary or as may be required, in the opinion of
counsel to Lender, to effect the transactions contemplated hereby and to extend
the liens and/or security interests of all other collateral instruments, as
modified by this Amendment, including, without limitation, any modifications to,
or re-filing of any financing statements previously held by Lender related to
the Loans to reflect the change in Borrower's name. Borrower also agrees to
provide to Lender such other documents and instruments as Lender reasonably may
request in connection with the modification of the Loans effected hereby.

     Section 3.7. Usury Savings Clause. Notwithstanding anything to the contrary
in this Amendment, the Amended Notes or any other Loan Document, or in any other
agreement entered into in connection with the Amended Notes or securing the
indebtedness evidenced by the Amended Notes, whether now existing or hereafter
arising and whether written or oral, it is agreed that the aggregate of all
interest and other charges constituting interest, or adjudicated as constituting
interest, and contracted for, chargeable or

                                     Page 3

<PAGE>

receivable under the Amended Notes or otherwise in connection with the Amended
Notes shall under no circumstances exceed the maximum rate of interest permitted
by applicable law. In the event the maturity of the Amended Notes is accelerated
by reason of an election by the holder thereof resulting from a default
thereunder or under any other document executed as security therefore or in
connection therewith, or by voluntary prepayment by the maker, or otherwise,
then earned interest may never include more than the maximum rate of interest
permitted by applicable law. If from any circumstance any holder of any of the
Amended Notes shall ever receive interest or any other charges constituting
interest, or adjudicated as constituting interest, the amount, if any, which
would exceed the maximum rate of interest permitted by applicable law shall be
applied to the reduction of the principal amount owing on such Amended Notes or
on account of any other principal indebtedness of the maker to the holders of
such Amended Notes, and not to the payment of interest, or if such excessive
interest exceeds the unpaid balance of principal thereof and such other
indebtedness, the amount of such excessive interest that exceeds the unpaid
balance of principal thereof and such other indebtedness shall be refunded to
the maker. All sums paid or agreed to be paid to the holder of the Amended Notes
for the use, forbearance or detention of the indebtedness of the maker to the
holder of such Amended Notes shall be amortized, prorated, allocated and spread
throughout the full term of such indebtedness until payment in full for the
purpose of determining the actual rate on such indebtedness is uniform
throughout the term thereof.

     The terms "maximum amount" or "maximum rate" as used in this Amendment or
the Amended Notes, or in any other agreement entered into in connection with the
Amended Notes or securing the indebtedness evidenced by the Amended Notes,
whether now existing or hereafter arising and whether written or oral, include,
as to Chapter 303 of the Texas Finance Code (and as same may be incorporated by
reference in other statutes of the State of Texas), but otherwise without
limitation, that rate based upon the "weekly ceiling"; provided, however, that
this designation shall not preclude the rate of interest contracted for, charged
or received in connection with the Loans from being governed by, or construed in
accordance with, any other state or federal law, including but not limited to,
Public Law 96-221.

     Section 3.8. Non-Waiver of Events of Default. Except as specifically
provided herein, neither this Amendment nor any other document executed in
connection herewith constitutes or shall be deemed (a) a waiver of, or consent
by Lender to, any default or event of default which may exist or hereafter occur
under any of the Loan Documents, (b) a waiver by Lender of any of Borrower's
obligations under the Loan Documents, or (c) a waiver by Lender of any rights,
offsets, claims, or other causes of action that Lender may have against
Borrower.

     Section 3.9. Enforceability. In the event the enforceability or validity of
any portion of this Amendment, the Loan Agreement, the Amended Notes, or any of
the other Loan Documents is challenged or questioned, such provision shall be
construed in accordance with, and shall be governed by, whichever applicable
federal or Texas law would uphold or would enforce such challenged or questioned
provision.

     Section 3.10. Counterparts. This Amendment may be executed in several
counterparts, all of which are identical, each of which shall be deemed an
original, and all of which counterparts together shall constitute one and the
same instrument, it being understood and agreed that the signature pages may be
detached from one or more of such counterparts and combined with the signature
pages from any other counterpart in order that one or more fully executed
originals may be assembled.

     Section 3.11. Choice of Law. THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, EXCEPT TO THE
EXTENT FEDERAL LAWS PREEMPT THE LAWS OF THE STATE OF TEXAS.

     Section 3.12. Entire Loan Agreement. This Amendment, together with the
other Loan Documents, contain the entire agreements between the parties relating
to the subject matter hereof and thereof. This Amendment and the other Loan
Documents may be amended, revised, waived, discharged, released or terminated
only by a written instrument or instruments, executed by the party against which

                                     Page 4

<PAGE>


enforcement of the amendment, revision, waiver, discharge, release or
termination is asserted. Any alleged amendment, revision, waiver, discharge,
release or termination which is not so documented shall not be effective as to
any party.

     THIS AMENDMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT
BETWEEN THE PARTIES RELATED TO THE SUBJECT MATTER THEREIN CONTAINED AND MAY NOT
BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

     IN WITNESS WHEREOF, this Amendment is executed effective as of the date
first written above.
