              (ii)   to Stonestreet Corporation (the "GENERAL PARTNER") 150,000
                     warrants, each warrant entitling the holder to purchase one
                     common share of the Company at $0.14 per share from
                     December 22, 2002 until December 31, 2004 (the "FEE
                     WARRANTS").

         (b)  The Fee Warrants shall be evidenced by a certificate (the "FEE
              WARRANT CERTIFICATE") in the form of Exhibit D, and shall be
              issued and delivered to the General Partner on the Closing Date.
              The General Partner agrees that the legending requirements set out
              in section 4(d) herein also apply to the Fee Warrant Certificate
              and to certificate representing common shares issuable upon
              exercise of the Fee Warrants (the "FEE WARRANT SHARES").

         (c)  The General Partner hereby represents that it is an "accredited
              investor" pursuant to Rule 45-501 as evidenced by the Accredited
              Investor Certificate attached hereto as SCHEDULE 2 completed and
              signed by the General Partner, and is acquiring the Fee Warrants
              as principal for its own account for investment purposes and not
              with a view to resale or distribution.

         (d)  All the representations, covenants, warranties, undertakings,
              remedies, indemnification, and other rights made or granted to or
              for the benefit of the Subscriber are hereby also made and granted
              to the General Partner and its successors and assigns in respect
              to the Fee Warrants and the Fee Warrants Shares.

         (e)  The Company on the one hand, and the Subscriber on the other hand,
              agree to indemnify the other against and hold the other harmless
              from any and all liabilities to any persons claiming brokerage
              commissions or due diligence fees other than the Consultant and
              the General Partner on account of services purported to have been
              rendered on behalf of the indemnifying party in connection with
              this Agreement or the transactions contemplated hereby and arising
              out of such party's actions. The Company and the Subscriber each
              represents that, to its knowledge, there are no parties entitled
              to receive commissions or similar payments in connection with the
              Offering.

10.      Maximum Investment Limitation

         (a)  The Company shall not issue any Shares to the Subscriber, nor
              issue the Fee Warrant Shares to the General Partner, if:

              (i)    the number of common shares beneficially owned by the
                     Subscriber and its affiliates on the date of issue, and

              (ii)   the number of common shares to be issued to the Subscriber
                     and its affiliates,

              would result in beneficial ownership by the Subscriber and its
              affiliates of more than 19.99% of the outstanding common shares of
              the Company on such date of issue (the "MAXIMUM INVESTMENT
              LIMITATION"). For the purposes of this provision, beneficial
              ownership shall be determined in accordance with Section 13(d) of
              the Securities
<PAGE>
                                       10


              Exchange Act of 1934, as amended, and Regulation 13d-3 thereunder.
              Subject to the foregoing, the Subscriber shall not be limited to
              aggregate issuance of only 19.99% and aggregate issuance of common
              shares to the Subscriber may exceed 19.99%. The Subscriber may
              void the Maximum Investment Limitation described in this provision
              upon 75 days prior written notice to the Company. The Subscriber
              may determine which of the equity of the Company deemed
              beneficially owned by the Subscriber is to be allocated to the
              19.99% amount described above and which to be allocated to the
              excess above 19.99%.

         (b)  Any interest accrued on the Notes that are not paid in Interest
              Shares when due as a result of the Maximum Investment Limitation
              must be paid by the Company to the Subscriber in cash.

         (c)  For the purposes of determining the percentage holdings of the
              Subscriber and its affiliates, the Subscriber agrees to notify the
              Company in writing identifying the Subscriber's affiliates. Prior
              to any issuance of any Shares to the Subscriber or its affiliates,
              the Company shall calculate and advise the Subscriber as to how
              many common shares of the Company the Subscriber and its
              affiliates hold according to the Company's records. The Company is
              entitled to rely conclusively on the Holder's notice with respect
              to the identities of the Holder's affiliates and will not be held
              liable and the Holder will have no cause of action whatsoever for
              the failure by the Company to comply with the Maximum Investment
              Limitation as a result of any inaccuracy in such notification from
              the Holder.

         (d)  The Company agrees to reject any portion of a conversion notice
              delivered by the Subscriber to the Company with respect to the
              conversion of any Note, any portion of a subscription form
              delivered by the Subscriber to the Company with respect to the
              exercise of any Warrant, and any portion of a subscription form
              delivered by the General Partner to the Company with respect to
              the exercise of any Fee Warrant, which, if converted or exercised,
              would result in a contravention of the Maximum Investment
              Limitation, and any such portion of the subscription notice or
              subscription form, as the case may be, shall be deemed to be null
              and void with respect the conversion or exercise for which the
              subscription form or the exercise form is delivered. Any portion
              of a conversion notice or subscription form, as the case may be,
              rejected in accordance with this clause (c) may be converted or
              exercised, as the case may be, at a subsequent time, subject to
              the Maximum Investment Limitation.

                     investors upon terms no more favourable to the investor(s)
