         Copies of all payments shall be sent to Joseph Gunnar & Co., LLC, 30
Broad Street, New York, NY 10004, Attn: Stephan A. Stein, via facsimile (212)
440-9668 (Joseph Gunnar & Co., LLC is hereinafter referred to as the "Placement
Agent").

         Any payment by the Company pursuant to this Note shall be made without
set-off or counterclaim and in immediately available funds.

         The Company (i) waives presentment, demand, protest or notice of any
kind in connection with this Note and (ii) agrees, in the event of an Event of
Default (as defined in Section 5 below), to pay to the holder of this Note, on
demand, all costs and expenses (including reasonable legal fees) incurred in
connection with the enforcement and collection of this Note.

         In consideration for the loan represented by this Note, the Company
shall issue to the Payee, simultaneously herewith, a warrant to purchase _____
shares of Common Stock, which shares of Common Stock upon proper exercise of the
warrant shall be duly authorized, validly issued, fully paid and non-assessable.

         1. [Reserved.]

         2. Secured Loan. The obligations of the Company hereunder and under
similar notes aggregating the principal amount of up to $_____, with an
over-allotment option of $______, are secured by a General Security Agreement
dated as of ______, 2006 (the "Security Agreement"). This Note is part of a Unit
issue (the "Offering") conducted by the Company pursuant to the Confidential
Private Placement Memorandum dated _______, 2006 (including all Appendices
thereto, the "Offering Documents").

         3. Computation of Interest.

                  A. Base Interest Rate. Subject to subsections 3B, 3C and 5C
below, the outstanding Principal Amount shall bear interest at the rate set
forth above.

                  B. Penalty Interest. In the event the Note is not repaid on
the Maturity Date, the rate of interest applicable to the unpaid Principal
Amount shall be increased to fifteen percent (15%) per annum from and after the
Maturity Date provided, that in no event shall the interest rate exceed the
Maximum Rate provided in Section 3C below.

                  C. Maximum Rate. In the event that it is determined that,
under the laws relating to usury applicable to the Company or the indebtedness
evidenced by this Note ("Applicable Usury Laws"), the interest charges and fees
payable by the Company in connection herewith or in connection with any other
document or instrument executed and delivered in connection herewith cause the
effective interest rate applicable to the indebtedness evidenced by this Note to
exceed the maximum rate allowed by law (the "Maximum Rate"), then such interest
shall be recalculated for the period in question and any excess over the Maximum
Rate paid with respect to such period shall be credited, without further
agreement or notice, to the Principal Amount outstanding hereunder to reduce
said balance by such amount with the same force and effect as though the Company
had specifically designated such extra sums to be so applied to principal and
the Payee had agreed to accept such extra payment(s) as a premium-free
prepayment. All such deemed prepayments shall be applied to the principal
balance payable at maturity. In no

                                        2
<PAGE>

event shall any agreed-to or actual exaction as consideration for this Note
exceed the limits imposed or provided by Applicable Usury Laws in the
jurisdiction in which the Company is resident applicable to the use or detention
of money or to forbearance in seeking its collection in the jurisdiction in
which the Company is resident.

the Company shall set aside on its books adequate reserves in accordance with

period. In the event the Company is in default on any of the Default Period
Payments, the Holder shall be entitled to (a) an increase in the interest on the
Notes at the rate of 18% per annum, (b) any contract or other remedies
prescribed by law and equity, and (c) election of such number of the Company's
Board of Directors as shall equal 50% of the resulting number of Board members
for so long as the default continues and remains uncured by the Company with

interest increase to 15% per annum.
