If maker defaults in the payment of this note, and the default continues after
Payee gives Maker notice of the default and the time within which it must be
cured, as may be required by law or by written agreement, then Payee may
declare the unpaid principal balance and the earned interest on this note
immediately due.  Maker and each surety, endorser, and guarantor waive all
demands for payment, presentations for payment, notices of intention to
accelerate maturity, notices of actual acceleration of maturity, protests and
notices of protest.

If this note is given to an attorney for collection, or if suit is brought for

due unless either party pleads otherwise.

Interest on the debt evidenced by this note shall not exceed the maximum amount
of non-usurious interest that may be contracted for, taken, reserved, charged,
or received under law; any interest in excess of that maximum amount shall be
credited on the principal of the debt or, if that has been paid, refunded.  On
any acceleration or required or permitted prepayment, any such excess shall be
cancelled automatically as of the acceleration or prepayment or, if already
paid, credited on the principal of the debt or, if the principal of the debt
has been paid, refunded.  This provision overrides other provisions in this and
all other instruments concerning the debt.

Maker may prepay this note in any amount at any time before maturity without
penalty.  Any prepayment should be applied first toward the payment of accrued
interest and next to the principal installments of the note, if any, in the
