Payment of principal and interest shall be made in lawful money of the United States of America at the address of Holder as referenced herein or at such other place as Holder shall have designated to the Maker in writing. This Note shall have the following additional terms and provisions: 1. Principal Payment. If not sooner paid, the principal amount of this Note shall be paid on September 8, 1999 (the "Maturity Date"). 2. Interest.

Interest on this Note shall be computed on a 365/365 simple interest basis, that is, by applying the ratio of the annual interest rate divided by the number of days in the year times the outstanding principal balance times the actual number of days the principal balance is outstanding. 3. Payment; Prepayment. This Note may be prepaid in whole or in part at any time without prior notice or penalty.

Events of Default; Acceleration. The following shall constitute "Events of Default" under this Note: 2 (i) A default by the Maker in the payment of any part of the principal amount or interest of this Note within ten (10) days after the same shall become due and payable, whether at the Maturity Date or at any other date fixed for payment.
