          3. TERMS OF THE NOTE.

          3.1. Amount. The principal amount of the Note shall be $500,000.

          3.2. Maturity. Unless otherwise converted into the Conversion Shares
(as defined in Section 3.4 hereof) in accordance with the provisions hereof, the
Note shall mature on December 1, 2008, unless such date shall be otherwise

Date"). On the Maturity Date, unless, and to the extent, converted into
Conversion Shares in accordance with the provisions hereof, all outstanding
principal and any accrued and unpaid interest due and owing under the Note shall
be immediately paid by Seller.

          3.3. Interest; Interest Rate; Payment. (a) The Note shall bear
interest (other than interest accruing as a result of a failure by Seller to pay
any amount when due as set forth in clause (b) below) at a rate equal to ten
(10%) percent (the "Interest Rate") per annum on a 360-day year. Interest (other
than interest accruing as a result of a failure by Seller to pay any amount when
due as set forth in subparagraph (b) below) shall be due and payable in cash
semi-annually in arrears following the end of each semi-annual period,
commencing with the semi-annual period ended June 30, 2006, pro rated for
partial periods; provided, however, that any interest accruing on overdue
amounts pursuant to subparagraph (b) of this Section 3.3 shall be payable on
demand.

               (b) If all or a portion of the principal amount of the Note or
any interest payable thereon shall not be repaid when due whether on the
applicable repayment date, by acceleration or otherwise, such overdue amounts
shall bear interest at a rate per annum that is three percent (3%) above the
Interest Rate (i.e., 13%) from the date of such non-payment until such amount is
paid in full (as well after as before judgment).


                                        2



               (c) All payments to be made by Seller hereunder or pursuant to
the Note shall be made, without setoff or counterclaim, in lawful money of the
United States by check or wire transfer in immediately available funds.

          3.4. Conversion. (a) Subject to Sections 3.4(b) and 3.5 hereof, at any
time prior to the Maturity Date, the Seller shall have the option to convert the
entire principal and interest accrued and owing on the Note, or any portion of
the principal and/or interest thereof, into shares (the "Conversion Shares") of
Common Stock at the Conversion Price. For purposes hereof, "Conversion Price"
shall mean $2.40 per share; PROVIDED, that if at any time on or after the
issuance date of the Note, Seller subdivides (by any stock split, stock
dividend, recapitalization, reorganization, reclassification or otherwise) its
shares of Common Stock into a greater number of shares, then after the date of
record for effecting such subdivision, the Conversion Price shall be
proportionately reduced, or if Seller combines (by reverse stock split,
recapitalization, reorganization, reclassification or otherwise) its shares of
Common Stock into a smaller number of shares, the Conversion Price shall be
proportionately increased.

Upon conversion, Buyer shall be entitled to receive the number of Conversion
Shares calculated by dividing the amount being converted by the Conversion
Price. No fractional shares of Conversion Shares shall be issued upon
conversion. In lieu of any fractional shares to which Buyer would otherwise be
entitled, Seller shall pay cash in an amount equal to such fraction multiplied
by the Conversion Price. The Note shall not be subject to automatic conversion
or to any conversion at the option of Seller.

               (b) Notwithstanding the provision of Section 3.4(a), if an equity
security or other derivative security convertible or exercisable into an equity
security of the Company ("Applicable Security") is sold in connection with a
Qualified Financing (as hereinafter defined) at any time prior to payment in
full of the principal balance of the Note, all of the principal and interest due
thereunder shall automatically become converted into the Applicable Security
with the same rights and privileges granted to investors in the Qualified
Financing. The number of Applicable Securities received upon conversion pursuant
to this Section 3(b) shall be determined by dividing the aggregate principal
amount due under the Note, together with any accrued but unpaid interest to the
date of conversion, by the price per Applicable Security paid in the Qualified
Financing. For the purposes of the Note, a "Qualified Financing" shall mean the
Company's next private financing of Applicable Securities to investors (i)
yielding aggregate gross proceeds (exclusive of conversion of the Note) to the
Company of at least $500,000 and (ii) which does not invoke or trigger the
provisions of Section 4(b) of the Debentures or Section 6(c) of the Warrants (as
such term is defined in the Securities Purchase Agreement.

          3.5. Conversion Procedures. In order to exercise the conversion rights
set forth in Section 3.4(a) hereof, Buyer shall surrender the Note,
appropriately endorsed, to Seller at Seller's principal office, accompanied by
written notice to Seller setting forth the amount of principal and interest to
be converted, the name or names (with address(es)) in which the Conversion
Shares issuable upon such conversion shall be issued and registered on the books
of Seller. For purposes hereof, the "Conversion Date" shall be deemed to be the
date the Note and notice is received by Seller for conversion. Within five (5)
business days after the Conversion Date, Seller shall deliver to Buyer (i) a
stock certificate for the Conversion Shares or (ii) a notice


                                        3



certified by Seller's Secretary that the Conversion Shares due on such
conversion have been issued to and registered on the books of Seller in the name
or names specified by Buyer. In the case of conversion of less than the entire
principal of and interest under the Note, Seller shall cancel said Note and
shall execute and deliver a new Note of like tenor for the unconverted amount of
the Note dated the date of execution by Seller upon initial issuance of the Note
notwithstanding any subsequent substitution.

          3.6. Subordination. The Note is expressly and fully subordinated, as
to payment and liquidation, to the payment in full of the Debentures and the
Obligations (as such term is defined in the Securities Purchase Agreement) and
the holder of the Note acknowledges and agrees that the Seller is expressly
restricted from pre-paying any amounts in respect of the principal of the Note
(upon acceleration or otherwise) until payment in full of the Debentures. The
holder of this Note shall not commence any judicial or other collection efforts
or exercise any other remedies prior to the date that is ninety-one (91) days
following the payment in full of the Debentures. The Note is, and is intended to
be, "Subordinated Debt" as such term is defined in the Securities Purchase
Agreement.

          3.7. Prepayment Rights Upon Merger, Consolidation, etc. (a) If, prior
to the Conversion Date, but subject to the provisions of Section 3.6 above,
Seller proposes to consolidate with, or merge into, another corporation or
entity, or to effect any sale or conveyance to another corporation or entity of
all or substantially all of the assets of Seller, or effect any other corporate
reorganization, in which the stockholders of the Seller immediately prior to
such consolidation, merger or reorganization own capital stock of the entity
surviving such merger, consolidation or reorganization representing less than
fifty (50%) percent of the combined voting power of the outstanding securities
of such entity immediately after such consolidation, merger or reorganization
(collectively, a "Liquidation Event"), then Seller shall provide Buyer with at
least ten (10) days' prior written notice of any such proposed action, and Buyer
will, at its option, have the right to demand immediate prepayment of all
amounts due and owing under the Note. Buyer will give Seller written notice of
such demand within five (5) days after receiving notice of the Liquidation
Event. All amounts (including all accrued and unpaid interest) due and owing
under the Note shall be paid by Seller to Buyer within five (5) days from the
date of such written notice via federal funds wire transfer(s) of immediately
available funds, in accordance with written instructions to be provided to
Seller by Buyer within at least two (2) business days after giving Seller such
written notice. The provisions of this Section 3.7(a) shall similarly apply to
successive consolidations or mergers.

          (b) Except as set forth in Sections 3.6, 3.7(a) and 9 hereof, Seller
shall not prepay prior to the Maturity Date all or part of this Note without the
express written consent of Buyer.

          3.8 Intentionally Deleted

          3.9 Assurances With Respect of Conversion Rights. Seller shall not, by
amendment of its Certificate of Incorporation or By-laws or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by Seller but shall at all times in good faith assist in the carrying
out of

such other further actions as may be reasonably required to carry out the
provisions hereof and effectuate the transactions contemplated hereby, and in
