           Documents and to perfect Bank's security interest in the
           Collateral.


 Borrower agrees to pay and reimburse Bank for all reasonable costs and
 expenses, including reasonable attorney's fees, incurred by or on behalf
 of Bank in connection with the Loan Documents or the transaction described
 herein.

 This agreement shall be binding upon and inure to the benefit of the
 parties hereto and their respective successors and assigns, including each
 transferee, assignee, endorser or holder of the Note, but Borrower may not
 assign this agreement or any of the other Loan Documents without the express
 prior written consent of Bank.

 This agreement shall remain in force for all renewals, extensions and
 modifications of the Note, if any, unless the agreement is modified or
 replaced in writing.

 This agreement and the other loan documents shall be governed by and
 construed in accordance with the applicable laws of the State of Texas and
 the United States of America from time to time in effect. This agreement
 and the other Loan Documents are performable in Dallas County, Texas, which
 shall be a proper place of venue for suit on or in respect of this agreement
 or the other Loan Documents.  Texas Revised Civil Statutes Annotated,
 Article 5069-1.04, as amended, Chapter 15, which regulates certain revolving
 credit loan accounts and revolving tri-party accounts, shall not apply to
 this agreement, the Note or the other Loan Documents.

 Notwithstanding any provision to the contrary contained in this agreement,
 the Note or any of the other Loan Documents, it is expressly provided that
 in no case or event shall the aggregate of any amounts accrued or paid
 pursuant to this agreement, the Note or any of the other Loan Documents
 which under applicable laws are or may be deemed to constitute interest ever
 exceed the maximum nonusurious interest rate permitted by applicable Texas
 or federal laws, whichever permits the higher rate.  In this connection,
 Borrower and Bank stipulate and agree that it is their common and overriding
 intent to contract in strict compliance with applicable usury laws.   In
 furtherance thereof, none of the terms of this agreement, the Note or any
 of the other Loan Documents shall ever be construed to create a contract
 to pay, as consideration for the use, forbearance or detention of money,
 interest at a rate in excess of the maximum nonusurious  interest rate
 permitted by applicable laws.   Borrower shall never be liable for interest
 in excess of the maximum nonusurious interest rate permitted by applicable
 laws.  If, for any reason whatever, such interest paid or received during
 the full term of this agreement, the Note or any of the other Loan Documents
 produces a rate that exceeds the maximum nonusurious interest rate permitted
 by applicable laws, Bank shall credit against the principal of such
 indebtedness (or, if such indebtedness shall have been paid in full, shall
 refund to the payor of such interest) such portion of said interest as shall
 be necessary to cause the interest paid to produce a rate equal to the
 maximum nonusurious interest rate permitted by applicable laws.

 All sums paid or agreed to be paid to Bank for the use, forbearance or
 detention of money shall, to the extent permitted by applicable law, be
 amortized, prorated, allocated and spread in equal parts throughout the
 full term of the applicable indebtedness, so that the interest rate is
 uniform throughout the full term of such indebtedness.  The provisions
 of this paragraph shall control all agreements, whether now or hereafter
 existing and whether written or oral, between Borrower and Bank.

 The terms and conditions of this agreement (in its entirety) shall survive
 the closing of the Loan Documents and shall evidence the Agreement between
 Borrower and Bank.  In the event of conflict between the Agreement and any
 of the Note, Guaranty, or Security Agreement the Note, Guaranty or Security
 Agreement shall control.

 If the foregoing correctly sets forth our agreement, please so indicate by
 executing the enclosed copy of this letter and return it to the undersigned.
