Borrower promises to pay to the order of Lender the Principal Amount. This note is payable at the Place for Payment and according to the Terms of Payment. All unpaid amounts are due by the Maturity date. After maturity, Borrower promises to pay any unpaid principal balance plus interest at the Annual Interest Rate on Matured, Unpaid Amounts.

If Borrower defaults in the payment of this note or in the performance of any obligation in any instrument securing or collateral to this note, Lender may declare the unpaid principal balance, earned interest, and any other amounts owed on the note immediately due. Notwithstanding any other provision of this note, in the event of a default, before exercising any of Lender's remedies under this note or any deed of trust or warranty deed with vendor's lien securing it, Lender will first give Borrower written notice of default and Borrower will have ten days after notice is given in which to cure the default. If the default is not cured ten days after notice, Borrower and each surety, endorser, and guarantor waive all demand for payment, presentation for payment, notice of intention to accelerate maturity, notice of acceleration of maturity, protest, and notice of protest, to the extent permitted by law.

Borrower also promises to pay reasonable attorney's fees and court and other costs if this note is placed in the hands of an attorney to collect or enforce the note. These expenses will bear interest from the date of advance at the Annual Interest Rate on Matured, Unpaid Amounts. Borrower will pay Lender these expenses and interest on demand at the Place for Payment. These expenses and interest will become part of the debt evidenced by the note and will be secured by any security for payment.

Prepayment: Borrower may prepay this note in any amount at any time before the Maturity Date without penalty or premium.

Interest on the debt evidenced by this note will not exceed the maximum rate or amount of nonusurious interest that may be contracted for, take reserved, charged, or received under law. Any interest in excess of that maximum amount will be credited on the Principal Amount or, if the Principal Amount has been paid, refunded. On any acceleration or required or permitted prepayment, any excess interest will be canceled automatically as of the acceleration or prepayment or, if the excess interest has already been paid, credited on the Principal Amount or, if the Principal Amount has been paid, refunded. This provision overrides any conflicting provisions in this note and all other instruments concerning the debt.

Each Borrower is responsible for all obligations represented by this note.

If any installment becomes overdue for more than fifteen days, at Lender's option a late payment charge of $25.00 maybe charged in order to defray the expense of handling the delinquent payment.
