  Capitalized terms used, but not otherwise defined, herein shall have the
  meaning given such terms in the Credit Agreement.
                     Maker may prepay this Note in whole or in part as provided
  in the Credit Agreement without . being required to pay any penalty or
  premium for such privilege. All prepayments hereunder, whether designated as
  payments of principal or interest, shall be applied in Payee's discretion to

 Note at the time in question. Texas Finance Code, Chapter 346, which regulates
 certain revolving loan accounts and revolving tri-party accounts, shall not
 apply to any revolving loan accounts created under this Note or the other Loan

 and ederal laws in connection with the above transaction.
          Any check, draft, money order or other instrument given in payment of
 all or any portion hereof .may be accepted by Payee and handled in
 collection in the customary manner, but the same shall not
 constitute payment hereunder or diminish any rights of Payee except to the
 extent that actual cash proceeds of such instrument are unconditionally
 received by Payee.

 governed by and construed under the laws of the State of Texas.

           respect to any warranty, representation, covenant or indemnification
           contained therein or in this letter shall be limited to an amount
           equal to the amounts disbursed by you to Collateral Agent hereunder.
          2. . Mortgagor hereby agrees that you are relieved of any
          responsibility in connection with the application of the proceeds paid
          by you to CoUateral Agent as hereinabove specified and payment made by

          and Mortgagor.
