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

The interest rate is 1.000% per year. The interest rate may only be changed in accordance with SOP 50 10.

From the date hereof ("Effective Date") to the date that is six (6) months from the Effective Date, and so long as no Default has occurred and is continuing, no payments of principal or interest will be required under this Note.

On the Maturity Date, Borrower shall pay the remaining balance of principal and all accrued interest and other amounts due hereunder in full.

The "Payment Amount" shall be an amount determined by Lender on the Payment Commencement Date, and shall be equal to the total outstanding amount of principal and accrued interest hereunder on such date, amortized over a period of eighteen (18) months at the interest rate of 1.000% per annum.

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