Interest shall be computed on the basis of a 360-day year of twelve 30-day months and shall accrue and be payable on the Maturity Date.

        Payee at its address set forth above.

        4.     Prepayment. This principal amount of this Promissory Note and any accrued and unpaid interest thereon may be prepaid, in whole or in part, at any time by Maker without penalty or premium. Partial prepayments shall be applied first to accrued and unpaid interest and then to
