          to comply with any of the covenants of the Borrower herein or if any
          representation or warranty by the Borrower or by any guarantor herein
          is materially incomplete, incorrect, or misleading as of the date

          Documents shall be a reference to such document as modified herein.

3. RATIFICATION OF RELATED DOCUMENTS AND COLLATERAL. The Related Documents are

          passage of time or both, would be a default or an event of default
          under the Related Documents as modified herein has occurred and is
          continuing.

     4.2  There has been no material adverse change in the financial conditions
          of the Borrower or any other person whose financial statement has been
          delivered to the Bank in connection with the Note from the most recent

     4.3  Each and all representations and warranties of the Borrower in the
          Related Documents are accurate on the date hereof.

     4.5  The Note and the Related Documents as modified herein are the legal,
          valid, and binding obligations of the Borrower, enforceable against

          organization. The Borrower has the requisite power and authority to
          execute and deliver this agreement and to perform the obligations
          described in the Related Documents as modified herein. The execution
          and delivery of this agreement and the performance of the obligations
          described in the Related Documents as modified herein have been duly
          authorized by all requisite action by or on behalf of the Borrower.
          This agreement has been duly executed and delivered by or on behalf of
          the Borrower.

5. BORROWER COVENANTS. The Borrower covenants with the Bank:

     5.1  The Borrower shall execute, deliver, and provide to the Bank such
          additional agreements, documents, and instruments as reasonably
          required by the Bank to effectuate the intent of this agreement.

     5.2  The Borrower fully, finally, and forever releases and discharges the
          Bank and its successors, assigns, directors, officers, employees,

          equity, of the Borrower, whether now known or unknown to the Borrower,
          (i) in respect of the loan evidenced by the Note and the Related
          Documents, or of the actions or omissions of the Bank in any manner
          related to the loan evidenced by the Note or the Related Documents and

agreement.

7. INTEGRATION, ENTIRE AGREEMENT, CHANGE, DISCHARGE, TERMINATION, OR WAIVER. The
Note and the Related Documents as modified herein contain the complete
understanding and agreement of the Borrower and the Bank in respect of the loan
and supersede all prior representations, warranties, agreements, arrangements,
understandings, and negotiations. No provision of the Note or the Related
Documents as modified herein may be changed, discharged, supplemented,
terminated, or waived except in a writing signed by the party against whom it is
being enforced.

8. GOVERNING LAW AND VENUE. This agreement is delivered in the State of Texas
and governed by Texas law (without giving effect to its laws of conflicts). The
Borrower agrees that any legal action or proceeding with respect to any of its
obligations under the Note or this agreement may be brought by the Bank in any
state or federal court located in the State of Texas, as the Bank in its sole
discretion may elect. By the execution and delivery of this agreement, the
Borrower submits to and accepts, for itself and in respect of its property,
generally and unconditionally, the non-exclusive jurisdiction of those courts.
The Borrower waives any claim that the State of Texas is not a convenient forum
or the proper venue for any such suit, action or proceeding. This agreement
binds the Borrower and its successors, and benefits the Bank, its successors and
assigns. The Borrower shall not, however, have the right to assign the
Borrower's rights under this agreement or any interest therein, without the
prior written consent of the Bank.

9. COUNTERPART EXECUTION. This agreement may be executed in multiple
counterparts, each of which, when so executed, shall be deemed an original, but
all such counterparts, taken together, shall constitute one and the same
agreement.

addition to all amounts hereafter due under the Note and the Related Documents
as they may be modified herein, all accrued interest evidenced by the Note being
modified by this agreement and all accrued amounts due and payable under the
Related Documents shall continue to be due and payable until paid. Except for
the above-quoted modification(s), the Note, any Related Documents, and all the
terms and conditions thereof, shall be and remain in full force and effect with
the changes herein deemed to be incorporated therein. This agreement is to be

not release or affect the liability of any guarantor, surety or endorser of the
Note or release any owner of collateral securing the Note. The validity,
priority and enforceability of the Note shall not be impaired hereby. References
to the Related Documents and to other agreements shall not affect or impair the
absolute and unconditional obligation of the Borrower to pay the principal and
interest on the Note when due. The Bank reserves all rights against all parties
to the Note.
