Journal prime rate on the first business date in January for each year
thereafter. The Wall Street Journal prime rate is defined as the highest prime
rate published in the Wall Street Journal. The interest rate referenced herein
will become effective as of the date that the employment level at the Borrower's
Kinderhook, New York facility falls below 45 full-time equivalent employees.

         The Lender is not required to deliver any notice to the Borrower of a
change in the interest rate. However, upon request, the Lender shall provide the
Borrower with information regarding the dates and amounts of the change in the
interest rate. There is no maximum limit on the amount that the interest rate
