                                   SECTION 2A

                                 REVOLVING LOAN


        2A.1  Subject to the terms and conditions of this Agreement, and 
        provided no event or condition constituting a Default or an Event of
        Default has occurred:

        (a) General Terms.  The Bank shall lend and re-lend to the Borrower from
        time to time amounts which shall not exceed in the aggregate of the
        unpaid principal amount at any one time outstanding the sum of ONE
        MILLION DOLLARS ($1,000,000) provided (i) each request for borrowings
        hereunder shall be in increments of at least Ten Thousand Dollars
        ($10,000.00); and (ii) the Bank approves of the specific use for each
        such advance.

        (c) Interest Rate.  The unpaid principal amount of the Revolving Loan
        from time to time outstanding shall bear interest at a rate of interest
        per annum equal to the Bank's Prime Rate computed daily, for the actual
        number of days elapsed as if each full calendar year consisted of three
        hundred sixty (360) days. Each time the Bank's Prime Rate shall change,
        the rate of interest on the Revolving Loan shall change
        contemporaneously without notice to the Borrower, but in no event shall
        the rate on the Revolving Loan exceed the maximum rate of interest
        permitted by law.

        (d) Payments of Principal and Interest.  The unpaid principal balance of
        the Revolving Loan and all unpaid and accrued interest thereon shall be
        payable by the Borrower to the Bank on demand or in accordance with
        Subsection 8.1(a) in immediately available funds. Payment of interest
        shall occur monthly, in immediately available funds, on the first
        Business Day of the Bank of each month beginning on the first Business
        Day of the Bank in the month next succeeding the date of this Agreement.
        All payments of interest and principal, howsoever designated by the
        Borrower shall be applied first on account of accrued interest and the
        remainder of such payments, if any, on account of the unpaid principal
        balance.

        (g) Master Note.  The maximum amount of the Revolving Loan is evidenced
        by a Master Note dated October 29, 1993, together with an Allonge to
        Master Note attached hereto as Exhibit B, and the balance due from time
        to time on the Master

                                      -3-
