This Note is secured by the Security Agreement below and on page two, and is subject to all of the terms thereof, which are
incorporated by reference. Lender may, upon deeming itself insecure, or upon Borrower's default in payment or in the terms of this
or any other agreement Borrower may have with Lender declare the entire unpaid balance due and payable. The Borrower severally
waives demand, notice, and protest and any defense due to extensions of time or other indulgence by Lender or to any substitution of
collateral. If the interest rate on this Note is tied to an index stated above, that index is used solely to establish a base from
which the actual rate of interest payable under this Note will be figured, and is not a reference to any actual rate of interest
charged by any lender to any particular borrower. If the interest rate varies in accordance with a selected index, if that index
ceases to exist, Lender may substitute a similar index which will become the index. If there is a Default Rate shown above, it may
be applied to all periods of time in which a default exists. If this Note is payable in installments, each installment payment will
be due on the same day of the installment period as the day upon which payments commence unless otherwise specified. Failure to pay
this Note according to the specified terms shall constitute a default. If permitted by law and at Lender's option, interest up to
the highest rate permitted by law may be assessed on any interest which is past due as the result of any payment not being paid when
due. Lender shall have the right to hold or apply its own indebtedness or liability to Borrower in payment of, or to provide
collateral security for the payment of this Note either prior to or after the Maturity Date. If legal proceedings are instituted to
enforce the terms of this Note, Borrower agrees to pay all costs of the Lender in connection therewith, including reasonable
attorney fees.
