stipulations and agreements of the Agreement are incorporated
herein by reference, and are hereby made a part of this Note to
the same extent and with the same effect as if they were fully
set forth herein, and Maker hereby covenants to abide by and to

2.   Interest.  From the date hereof through and including the Maturity Date
(as hereinafter defined) no interest shall accrue on the

the unpaid principal sum of this Note shall bear interest at the
rate of twelve percent (12%) per annum (the "Default Interest
Rate").  Interest at the Default Interest Rate shall accrue
daily.  All computations of interest hereunder shall be made on
the basis of a year of 360 days, for the actual number of days
occurring in the period for which such interest is payable
(including the first day but excluding the last day).

Note shall be due and payable on the first to occur of:  (i)

(ii) the issuance, sale, transfer or assignment of shares of
Maker's stock resulting in a transfer of ownership or change in
control of Maker; or (iii) the third (3rd) anniversary of the
date hereof, unless accelerated by Payee (the "Maturity Date").

 4.       Prepayment.  Maker shall have the right, at any time, to prepay the
outstanding principal amount of this Note, in whole or in part
from time to time (without premium or penalty).

 5.     Application of Payments.  Each and all of the payments made hereunder
shall be applied first to expenses and costs incurred by Payee
and for which Maker is responsible; second, to any accrued and
unpaid fees; third, to accrued and unpaid interest hereunder, if
any; and, fourth, to the principal balance of this Note.

 6.     Security.  Payment of this Note is secured in accordance with Section

granted pursuant thereto or otherwise in connection therewith
and any other assignments and conveyances made from time to time
pursuant to the Agreement.

agreement executed by Maker pursuant to or in otherwise in
connection with the Agreement, (ii) fails in any way to observe
any covenant or agreement under this Note, the Working Capital
Note, the Agreement, or any other instrument, document or
agreement executed by Maker pursuant to or in otherwise in
connection with the Agreement, or (iii) fails to make any
payment when due under this Note or the Working Capital Note,
which default is not cured within ten (10) days, then, Payee, at
its option and without further notice to Maker, may declare
immediately due and payable the entire unpaid principal sum due
hereunder (with interest to accrue thereafter at the Default
Interest Rate), and all other charges and sums due by Maker
under this Note of the Agreement; and payment thereof may be
enforced and recovered in whole or in part at any time by one or
more of the remedies provided to Payee in the Agreement, or at
law or equity.  In such case Payee may also recover all costs of
suit and other expenses in connection therewith, together with
an attorneys' commission, for collection, of five percent (5%)
of the total amount then due by Maker to Payee, together with
interest on any judgment obtained by Payee at the Default Inter-
est Rate.  Payee may exercise this option to accelerate during
any default by Maker regardless of any prior forbearance.

sion, to have waived any of its rights or remedies hereunder
