     2.   CONVERSION; PAYMENT; ETC.
          ------------------------

          (a)     This  Note  shall  be  convertible at any time, in whole or in
part,  at  the  option  of  the  Holder,  into  such  number  of  fully paid and
nonassessable  shares  of  Common  Stock  of  the Company ("Common Stock") as is
determined  by  dividing (i) the entire principal amount of, and at the Holder's
option  accrued  interest on, this Note on the date of such optional conversion,
by (ii) a conversion price equal to the lesser of (i) US$0.175 per share or (ii)
seventy-five  percent (75%) of the lowest closing bid price for the Common Stock
(as  reported  by  Bloomberg)  in  any  of the five (5) trading days immediately
preceding  the  conversion  date.

          (b)     The  conversion price shall be subject to adjustment from time
     to  time  as  hereinafter  provided  in  this  Section  2(b):

          (i)       If the Company at any time divides the outstanding shares of
                    its Common Stock into a greater number of shares (whether
                    pursuant to a stock split, stock dividend or otherwise), and
                    conversely, if the outstanding shares of its Common Stock
                    are combined into a smaller number of shares, the conversion
                    price in effect immediately prior to


                                      - 1 -
<PAGE>
                    such division or combination shall be proportionately
                    adjusted to reflect the reduction or increase in the value
                    of each such common share.

          (ii)      If any capital reorganization or reclassification of the
                    capital stock of the Company, or consolidation or merger of
                    the Company with another corporation, or the sale of all or
                    substantially all of its assets to another corporation shall
                    be effected in such a way that holders of the Company's
                    Common Stock shall be entitled to receive stock, securities
                    or assets with respect to or in exchange for such Common
                    Stock, then, as a condition of such reorganization,
                    reclassification, consolidation, merger or sale, Holder
                    shall have the right to purchase and receive upon the basis
                    and upon the terms and conditions specified in this
                    debenture and in lieu of the shares of the Common Stock of
                    the Company immediately theretofore purchasable and
                    receivable upon the exercise of the rights represented
                    hereby, such shares of stock, other securities or assets as
                    would have been issued or delivered to Holder if Holder had
                    exercised this debenture and had received such shares of
                    Common Stock immediately prior to such reorganization,
                    reclassification, consolidation, merger or sale. The Company
                    shall not effect any such consolidation, merger or sale
                    unless prior to the consummation thereof the successor
                    corporation (if other than the Company) resulting from such
                    consolidation or merger or the corporation purchasing such
                    assets shall assume by written instrument executed and
                    mailed to the Holder at the last address of the Holder
                    appearing on the books of the Company the obligation to
                    deliver to the Holder such shares of stock, securities or
                    assets as, in accordance with the foregoing provisions, the
                    Holder may be entitled to purchase.

          (iii)     If  and  whenever  the  Company  shall (1) issue or sell any
                    shares of its Common Stock for a consideration per share
                    less than the conversion price in effect immediately prior
                    to the time of such issuance or sale, (2) issue or sell any
                    warrants, options or other rights to acquire shares of its
                    Common Stock at a purchase price less than the conversion
                    price in effect immediately prior to the time of such
                    issuance or sale or (3) issue or sell any other securities
                    that are convertible into shares of its Common Stock for a
                    purchase or exchange price less than the conversion price in
                    effect immediately prior to the time of such issuance or
                    sale then, upon such issuance or sale, the conversion price
                    shall be reduced to the price at which such shares of Common
                    Stock are being issued or sold by the Company or the price
                    at which such other securities are exercisable or
                    convertible into shares of the Company's Common Stock.

          (c)     No  fractional  shares  of the Company's capital stock will be
issued  upon  conversion of this Note.  In lieu of any fractional share to which
the  Holder  would  otherwise be entitled, the Company will pay to the Holder in
cash  the  amount of the unconverted principal and interest balance of this Note
that  would  otherwise be converted into such fractional share.  Upon conversion
of  this  Note pursuant to this Section 2, the Holder shall surrender this Note,
duly  endorsed, at the principal offices of the Company or any transfer agent of
the  Company.  At  its  expense,  the  Company  will,  as  soon  as  practicable
thereafter,  issue  and  deliver  to  such  Holder,  at such principal office, a
certificate  or  certificates  for  the number of shares to which such Holder is
entitled  upon  such conversion, together with any other securities and property
to which the


                                      - 2 -
<PAGE>
Holder  is entitled upon such conversion under the terms of this Note, including
a  check payable to the Holder for any cash amounts payable as described herein.
Upon  conversion  of  this  Note  and  the  deliveries required pursuant to this
Section  2  in  connection  with  such  conversion,  the Company will be forever
released from all of its obligations and liabilities under this Note with regard
to  that  portion  of  the principal amount and accrued interest being converted
including without limitation the obligation to pay such portion of the principal
amount and accrued interest.

NOTWITHSTANDING ANY OTHER PROVISION HEREOF, NO HOLDER SHALL CONVERT THIS NOTE OR
ANY  PORTION  THEREOF,  IF  AS A RESULT OF SUCH CONVERSION THE HOLDER WOULD THEN
BECOME  A  "TEN  PERCENT  BENEFICIAL  OWNER" (AS DEFINED IN RULE 16A-2 UNDER THE
SECURITIES  EXCHANGE  ACT  OF  1934,  AS  AMENDED) OF COMMON STOCK.  FOR GREATER
CERTAINTY,  THE  NOTE SHALL NOT BE CONVERTIBLE BY THE HOLDER TO THE EXTEND THAT,
IF,  AFTER  GIVING  EFFECT  TO  SUCH  CONVERSION, THE HOLDER OF SUCH SECURITIES,
TOGETHER  WITH  ITS AFFILIATES, WOULD IN AGGREGATE BENEFICIALLY OWN, OR EXERCISE
CONTROL  OR DIRECTION OVER THAT NUMBER OF VOTING SECURITIES OF THE COMPANY WHICH
IS  10%  OR GREATER OF THE TOTAL ISSUED AND OUTSTANDING VOTING SECURITIES OF THE
COMPANY,  IMMEDIATELY  AFTER  GIVING  EFFECT  TO  SUCH  CONVERSION.

          (d)     PAYMENT  OF INTEREST.  Upon conversion of the entire principal
                  --------------------
amount  of  this  Note into the Company's capital stock, any interest accrued on
this  Note  that  is  not by reason of Section 2 hereof simultaneously converted
into  Common  Stock  shall  be  immediately  paid  to  the  Holder.

          (e)     PAYMENT.  All  payments  shall  be made in lawful money of the
                  -------
United  States  of  America  at such place as the Holder hereof may from time to
time  designate  in  writing to the Company.  Payment shall be credited first to
the  accrued  interest  then  due  and  payable  and  the  remainder  applied to
principal.  This  Note  may not be prepaid at any time without the prior written
consent  of  the  Holder.

          (f)     SECURITY.  This  Note  is  secured  by  a security interest in
                  --------
substantially  all  of  the  Company's tangible and intangible assets (including
intellectual  property)  (collectively, the "Collateral"), granted to the Holder
under  a  Security  Agreement  dated July 29, 2005. A default under the terms of
this  Note  shall  also  constitute  a  default  under  the  Security Agreement.

     3.   DUE ON SALE CLAUSE.   The Holder shall have the right, at its sole
          -----------------
option,  to  declare  this  Note immediately due and payable irrespective of the
Maturity  Date  specified  herein,  upon  the  following  events:

          (a)     Twenty business days prior to the effective date of any Change
of Control transaction undertaken without the prior written consent of the
Holder, which consent the Holder shall have no obligation to give. A "Change of
Control Transaction" means (i) any sale of equity securities or securities
convertible into equity securities of the Company; (ii) any merger,
consolidation, statutory share exchange or acquisition transaction involving the
Company; (iii) any sale of substantially all of the assets of the Company; or
(iv) any similar transaction involving the issuance, cancellation or
restructuring of equity securities of the Company unless, following the
completion of such transaction, the then existing shareholders of Company own or
control, directly or indirectly, at least 50% of the voting power or liquidation
rights of Company or the successor of such merger, consolidation or statutory
share exchange.

          (b)     If the Company shall sell, convey, transfer, assign or further
encumber the Collateral or any part thereof or any interest therein, whether
legal or equitable, in any manner (whether voluntarily or involuntarily) not
permitted under the Security Agreement, without the prior written consent of the
Holder, which consent the Holder shall have no obligation to give. Any consent
by the Holder to such a transfer may be predicated upon such terms, conditions
and


                                      - 3 -
<PAGE>
covenants as may be deemed advisable or necessary in the sole discretion of the
Holder, including, but not limited to, the right to (i) require the transferee's
assumption of personal liability on the debt hereunder, (ii) approve the form
and substance of all transfer and assumption documents, (iii) change the
interest rate, date of maturity and amount and/or schedule of payments hereunder
and (iv) charge a fee based on a percentage of the original principal amount of
this Note. The granting of permission for a transferee of the Collateral to
assume this Note shall not in any manner be deemed a consent to any subsequent
transfer, and the Holder shall retain the right to consent to such subsequent
transfer or transfers on the terms and conditions stated above. Consent to one
such transfer shall not be deemed to be a waiver of the right of such consent to
further or successive transfers. No assumption or consent to any subsequent
transfer shall be deemed to constitute a release of the Company's obligations
hereunder.

which  would  be  in  violation of  such securities laws or adversely affect the
