     terms for this Note are:

     NOTE PAYABLE: FIFTEEN (15) years from the date of Note with interest at the
     rate of 9.000% per annum and installments including principal and accured
     interest payable MONTHLY, each in the amount of $6,596.04, commencing one
     MONTH from date of Note. Each said installment shall be applied first to
     interest accrued to the date of receipt of said installment, and the
     balance, if any, to principal. Balance of principal and interest payable on
     or before fifteen years from the date hereof.

     Interest rate shall be adjusted up or down QUARTERLY, and become effective
     as of the first business day of each QUARTER with adjustment period
     beginning April 1, 2000, based on .250% over the minimum prime rate as
     published daily in the Wall Street Journal. In no event shall the interest

     rate in effect as of the date of purchase by SBA.

3.   PAYMENT TERMS:

     Borrower must make all payments at the place Lender designates. The payment
     terms for this Note are:

          The interest rate on this Note will fluctuate. The initial interest
          rate is 9.0% per year. This initial rate is the prime rate on the date
          SBA received the loan application, plus .25%.

          Borrower must pay principal and interest payments of $6,596.00 every
          month, beginning one month from the month this Note is dated: payments
          must be made on the 1st calendar day in the months they are due.

          Lender will apply each installment payment first to pay interest
          accrued to the day Lender receives the payment, then to bring
          principal current, then to pay any late fees, and will apply any
          remaining balance to reduce principal.

          Lender may adjust the interest rate for the first time no earlier than
          the first calendar day of the first month after initial disbursement.
          The interest rate will then be adjusted quarterly (the "change
          period").

          The "Prime Rate" is the prime rate in effect on the first business day
          of the month in which a change occurs, as published in the Wall Street
          Journal on the next business day.

          The adjusted interest rate will be .25% above the Prime Rate. Lender
          will adjust the interest rate on the first calendar day of each change
          period. The change in interest rate is effective on that day whether
          or not Lender gives Borrower notice of the change.

          Lender must adjust the payment amount at least annually as needed to
          amortize principal over the remaining term of the note.

          If SBA purchases the guaranteed portion of the unpaid principal
          balance, the interest rate becomes fixed at the rate in effect at the
          time of the earliest uncured payment default if there is no uncured
          payment default. the rate becomes fixed at the rate in effect at the
          time of purchase.

          All remaining principal and accrued interest is due and payable 15
          years from date of Note.

          Late Charge : If a payment on this Note is more than 10 days late,
          Lender may charge Borrower a late fee of up to 5% of the unpaid
          portion of the regularly scheduled payment.
