be construed in accordance with and governed by the laws of the State of

transaction related hereto shall be construed or so operate as to require
Borrower or any person liable for the payment of this Note to pay interest in an
amount or at a rate greater than the maximum allowed by applicable laws in
effect from time to time. Should any interest or other charges in the nature of
the interest paid by Borrower or any parties liable for the payment of this Note

all such excess shall be and the same is hereby waived by Bank, and all such
excess received shall

                                       24

automatically be credited against and in reduction of the Principal, and any
portion of said excess which exceeds the Principal shall be paid by Bank to
Borrower or any parties liable for the payment of this Note, it being the intent

any provision of this Loan Agreement, any Loan Document, or of the Note, nor any
consent to any departure by BORROWER therefrom, shall in any event be effective
unless the same shall be in writing and signed by the BANK and then such waiver
or consent shall be effective only in the specific instance and for the purpose
for which given. No notice to or demand on BORROWER shall in any case entitle

be extended to the next succeeding business day, and, in the case of any
prepayment of principal, interest shall be payable thereon at the rate per annum
