loaned or advanced hereunder by Payee, less the amount of payments or
prepayments of principal made hereon by or for the account of
Maker.  It is contemplated that by reason of prepayments hereon, there

occurrences, this note shall remain valid and shall be in full force and effect
as to loans or advances made pursuant to and under the terms of this note
subsequent to each such occurrence.





Advances hereunder shall be made by
Payee upon the oral or written request of the undersigned officer of Maker or
any other officer of Maker authorized to make such a request.





Maker  promises to pay to the
order of Payee at the place for payment and according to the terms of payment
the principal amount plus interest at the rates stated above.  All
unpaid amounts shall be due  December 31, 2009.





On default in the payment of this note
or in the performance of any obligation in any instrument securing or collateral
to it this note and all obligations in all instruments securing or collateral to
it shall become immediately due at the election of Payee.  Maker and
each surety, endorser, and guarantor waive all demands for payment,
presentations for payment, notices of intention to accelerate maturity,
protests, and notices of protest.





If this note or any instrument securing
or collateral to it is given to an attorney for collection, or if suit is
brought for collection, or if it is collected through probate, bankruptcy, or
other judicial proceeding, then Maker shall pay Payee all costs of collection,
including reasonable attorney's fees and court costs, in addition to other
amounts due.





Interest on the debt evidenced by this
note shall not exceed the maximum amount of nonusurious 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 canceled 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.





The terms Maker and Payee and other
nouns and pronouns include the plural if more than one.  The terms
Maker and Payee also include their respective successors, representatives, and
