         For value received, GLOBAL BERMUDA LIMITED PARTNERSHIP, a Bermuda
limited partnership with an office at 601 Carlson Parkway, Suite 200,

offices located at 55 City Centre Drive, Suite 500, Mississauga, Ontario, Canada
L5B 1M3 (hereinafter called the "Company"), in lawful currency of the United
States of America, the principal sum of FIFTY THOUSAND DOLLARS S$50,000.00),
with interest at 8% per annum.

         The following is a statement of the rights of the Lender of this
Debenture and the terms and conditions to which the Lender under this Debenture,
by his or her acceptance of this Debenture, agrees:

         1. Payment. All unpaid principal and interest accruing under this
Debenture (the "Unpaid Balance") will be paid to the Lender under this Debenture
as of 5:00 p.m. EST on the 365th day following the issuance date hereof, except
to the extent that such Unpaid Balance has been prepaid by the exercise of one
or more of the following rights: (a) the Lender under this Debenture has elected
under Section 2.1 hereof to convert the Unpaid Balance into shares of the Common
Stock, or (13) the Company has prepaid, in cash, the Unpaid Balance together
with a premium equal to 8% of such Unpaid Balance as a condition to such right
to prepay. All payments of principal and interest under this Debenture will be
made by check mailed to the address of record of the Lender under this Debenture
set forth in the records of the Company or to such other address as the Lender
under this Debenture shall have notified the Company in the manner set forth
below.

         2. Conversion. This Debenture shall be convertible to shares of the
Common Stock of the Company (the "Shares"), as follows:
   2
         2.1 Conversion Right. The Lender under this Debenture will have the
right, at any time commencing on the 121st day following the date of issuance of
this Debenture and prior to the payment in full of this Debenture, to convert
all of the Unpaid Balance of this Debenture into Shares of the Company at a
conversion price (the "Conversion Price") equal to the lower of US$5.00 or 80%
of the average closing bid price of the Shares, as quoted on the National
Association of Securities Dealers Automated Quotation ("Nasdaq") system over the
twenty (20) trading days immediately preceding the date of the Company's receipt
of the Lender's notice to the Company of its intention to convert, provided,
however, that this Debenture may not be converted until at least 30 days have
elapsed since the most recent prior conversion of any other of the debentures
issued by the Company to the Lender. The number of Shares into which any Unpaid
Balance may be converted shall equal the quotient obtained by dividing such
Unpaid Balance by the Conversion Price. This right of conversion shall
terminate, and Lender shall not thereafter submit this Debenture for conversion,
at such time as the Lender or any affiliate of the Lender shall have a short
position in the Common Stock of the Company.

         In the event the Company does not make delivery of the Common Stock, as
instructed by Purchaser, within 5 business days after delivery of the original
Debenture, then in such event the Company shall pay to Purchaser an amount, in
cash in accordance with the following schedule, wherein "No. Business Days Late"
is defined as the number of business days beyond the 5 business days delivery
period.

         The Company shall make any payments incurred under this Section in
immediately available funds within three (3) business days from the Conversion
Date if late. Nothing herein shall limit a Purchaser's right to pursue actual
damages or cancel the conversion for the Company's failure to issue and deliver
Common Stock to the Holder within 5 business days after the Conversion Date.

         2.2 Mechanics and Effect of Conversion. To convert this Debenture
pursuant to Section 2.1, the Lender under this Debenture shall surrender this
Debenture, duly endorsed, at the principal office of the Company together with a
written notice (the "Conversion Notice") to the Company of the Lender's election
to convert and Lender's confirmation that neither the Lender nor any affiliate
of the Lender has, at any time during the term of this Debenture, had a short
position in the Common Stock of the Company. At its expense, the Company, as
soon as practicable thereafter, shall either (i) issue and deliver to the Lender
at the Lender's address a certificate evidencing the issuance of that number of
Shares to which the Lender is entitled upon such conversion bearing only such
legend, if any, as may be required under applicable state or federal securities
laws), or (ii) at the Company's sole discretion, pay to Lender 100% of the
average closing bid price of the Shares, as quoted on the Nasdaq over the twenty
(20) trading days immediately preceding the date of the Company's receipt of the
Lender's notice to the Company of its intention to convert. In the event of a
conversion of this Debenture, such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender and
delivery of both this Debenture and the corresponding Conversion Notice, and the
Lender shall be entitled to receive the Shares issuable upon such conversion
shall be treated for all purposes as the record holder of such Shares on such
date.

         3.  Anti-Dilution; Reservation of Shares. In the event that, at any 
time that there is any Unpaid Balance on this Debenture, the Company makes a
distribution to its members in Shares of the Company, or subdivides or combines
the outstanding Shares of the Company (the foregoing collectively being referred
to as an "Adjustment Event"), the number of Shares issuable to the Lender upon
conversion or partial conversion of this Debenture shall be automatically
changed to equal the new number of Shares, or Shares and property, that the
Lender would have received if this Debenture was converted immediately prior to
the Adjustment Event. The Company covenants that it will, upon the occurrence of
an Adjustment Event, act to reserve and keep available solely for issuance upon
conversion of this Debenture, that number of Shares (and other securities) into
which this Debenture is then convertible.

         4.  Miscellaneous.

communications provided for herein shall be in writing and shall be deemed
