properties and other properties as set forth in the Agreement; and

         WHEREAS, all capitalized terms not otherwise defined herein shall have

         NOW THEREFORE, in consideration of the mutual covenants and agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Borrower and the Bank hereby
agree to amend the agreement as follows:

         A.       CHANGES TO THE AGREEMENT

                  1. Section 8.6 of the Agreement, DIVIDEND; TREASURY STOCK
PURCHASES, is hereby amended and restated in its entirety in order to evidence
Bank's consent to Borrower's payment of certain preferred stock dividends as
follows:

         the payment of dividends on the Preferred Stock shall not be construed

         Stock.

         B.       REPRESENTATIONS AND WARRANTIES

         Borrower hereby represents and warrants to Bank that:

                  1. Borrower is a corporation, duly organized, legally
existing, and in good standing under the laws of the State of Oklahoma, and is
duly qualified as a foreign corporation and in good standing in all other
states wherein the nature of its business or its assets make such qualification

                  2. Borrower's execution and delivery of this Amendment and
performance of its obligations hereunder: (a) are and will be within its powers;
(b) are duly authorized by its board of directors; (c) are not and will not be

consent or approval (including governmental) which has not been given; and (e)
will not result in the imposition of liens, charges or encumbrances on any of
its properties or assets, except those in favor of Bank hereunder.

                  3. This Amendment, when duly executed and delivered, will
constitute the legal, valid and binding obligations of Borrower, enforceable in

reports, papers and other data furnished to Bank are and will be, when

financial statements, no material adverse change has occurred in the operations
or condition, financial or otherwise and other financial data provided to Bank;

guarantees, direct or contingent, in any single case or in the aggregate, which
