               the Borrower's properties and examine, audit and make copies of
               books and records at any reasonable time. If any of the
               Borrower's properties, books or records are in the possession of
               a third party, the Borrower authorizes that third party to permit
               the Bank or its agents to have access to perform inspections or
               audits and to respond to the Bank's requests for information
               concerning such properties, books and records. The Bank has no
               duty to inspect the Borrower's properties or to examine, audit,
               appraise or copy books and records and the Bank shall not incur
               any obligation or liability by reason of not making any such
               inspection or inquiry. In the event that the Bank inspects the
               Borrower's properties or examines, audits, appraises, or copies
               books and records, the Bank will be acting solely for the
               purposes of protecting the Bank's security and preserving the
               Bank's rights under this Agreement. Neither the Borrower nor any
               other party is entitled to rely on any inspection or other
               inquiry by the Bank. The Bank owes no duty of care to protect the
               Borrower or any other party against, or to inform the Borrower or
               any other party of, any adverse condition that may be observed as
               affecting the Borrower's properties or premises, or the
               Borrower's business. The Bank may in its discretion disclose to
               the Borrower or any other party any findings made as a result of,
               or in connection with, any inspection of the Borrower's
               properties."

    2.9    Paragraph 9 of the Agreement is amended in its entirety as follows:

           "9. HAZARDOUS WASTE INDEMNIFICATION

            The Borrower will indemnify and hold harmless the Bank from any loss
            or liability directly or indirectly arising out of the use,
            generation, manufacture, production, storage, release, threatened
            release, discharge, disposal or presence of a hazardous substance.
            This indemnity will apply whether the hazardous substance is on,
            under or about the Borrower's property or operations or property
            leased to the Borrower. The indemnity includes but is not limited to
            attorneys' fees (including the reasonable estimate of the allocated
            cost of in-house counsel and staff). The indemnity extends to the
            Bank, its parent, subsidiaries and all of their directors, officers,
            employees, agents, successors, attorneys and assigns.  "Hazardous
            substances" means any substance, material or waste that is or
            becomes designated or regulated as "toxic," "hazardous,"
            "pollutant," or "contaminant" or a similar designation or regulation
            under any federal, state or local law (whether under common law,
            statute, regulation or otherwise) or judicial or administrative
            interpretation of such, including without limitation petroleum or
            natural gas. This indemnity will survive repayment of the Borrower's
            obligations to the Bank."

     2.10  Paragraph 11.7 of the Agreement is amended in its entirety as 
           follows: 

           "11.7 ATTORNEYS' FEES. The Borrower shall reimburse the Bank for any
           reasonable costs and attorneys' fees incurred by the Bank in
           connection with the enforcement or preservation of any rights or
           remedies under this Agreement and any other documents executed in
           connection with this Agreement, and in connection with any amendment,
           waiver, "workout" or restructuring under this Agreement.  In the 
           event of a lawsuit or arbitration proceeding, the prevailing party is
           entitled to recover costs and reasonable attorneys' fees incurred in
           connection with the lawsuit or arbitration proceeding, as determined
           by the court or arbitrator.  In the event that any case is commenced 
           by or against the Borrower under the Bankruptcy Code (Title 11, 
           United States Code) or any similar or successor statute, the Bank is
           entitled to recover costs and reasonable attorneys' fees incurred by
           the Bank related to the preservation, protection, or enforcement of 
           any rights of the Bank in such a case.  As used in this paragraph, 
           "attorneys' fees" includes the allocated costs of the Bank's 
           in-house counsel."
           
     3. Conditions. This Amendment will be effective when the Bank receives the 
following items, in form and content acceptable to the Bank:

        Sixty Two and 50/100 Dollars ($1,562.50) due on the date of execution of
