          Except as otherwise expressly provided herein, each maker, surety,
endorser, and guarantor of this Note hereby severally waives demand and
presentation for payment, notice of non-payment, protest and notice of protest,
and the diligence of bringing suit against any party hereto and consents that
time of payment may be extended from time to time without notice thereof to it.

          All amounts payable hereunder by the Maker shall be payable to the
Payee at the address set forth below or at such other place as the Payee or the

          This Note may be prepaid in whole or in part at any time and from time
to time without premium or penalty. Any partial prepayments shall be applied
first to any overdue interest and then to the outstanding principal installments
in inverse order of maturity.

          If any payment required to be made hereunder becomes due and payable
on a non-business day, the maturity thereof shall extend to the next business
day and interest shall be payable at the rate applicable thereto

option, may declare the entire unpaid balance of principal and accrued interest
hereunder to be immediately due and payable.  All past due payment of principal
and interest shall bear interest at the rate of twelve percent (12%) per annum
until paid.  Any payment made more than ten days after the due date of such

          In no contingency or event whatsoever shall the amount paid or agreed
to be paid by Maker, received by Payee, or requested or demanded to be paid by
Maker exceed the maximum amount permitted by applicable law.  In the event any
such sums paid to Payee by Maker would exceed the maximum amount permitted by
applicable law, Payee shall automatically apply such excess to the unpaid
principal amount of this Note or , if the amount of such excess exceeds the
unpaid principal amount of this Note, such excess automatically shall be applied
by Payee to the unpaid principal amount of other indebtedness, if any, owed by
Maker or Payee, or if there be no such other indebtedness, such excess shall be
paid to Maker.  All sums paid or agreed to be paid by Maker, received by Payee,
or requested or demanded to be paid by Maker  which are or hereafter may be
construed to be or in respect of compensation for the use, forbearance, or

amortized, prorated, spread and allocated throughout the full term of all
indebtedness of Maker to Payee, to the end that the actual rate of interest
hereon shall never exceed the maximum rate of interest permitted from time to
time by applicable law.
