in excess of the Maximum Rate, and, in the event that Holder ever receives,
collects, or applies as interest any such excess, such amount which would be
excessive interest shall be applied to the reduction of the unpaid principal
balance of this Note, and, if the principal balance of this Note is paid in
full, then any remaining excess shall forthwith be paid to the Company. In
determining whether or not the interest paid or payable under any specific
contingency exceeds the highest Maximum Rate, the Company and Holder shall, to
the maximum extent permitted under applicable law, (a) characterize any
non-principal payment (other than payments which are expressly designated as
interest payments hereunder) as an expense or fee rather than as interest, (b)
exclude voluntary or refinancing prepayments and the effect thereof, and (c)
spread the total amount of interest throughout the entire contemplated term of
this Note so that the interest rate is uniform throughout such
term.
