2. The Subscriber acknowledges (on its own behalf and, if applicable, on behalf of each person on whose behalf the Subscriber is contracting) that:

(a) the Debentures subscribed for by it hereunder form part of a larger issuance and sale by the Corporation of up to $30,000,000 (U.S.) principal amount of Debentures at an issue price of $1,000 (U.S.) per Debenture on a best efforts marketed offering basis through the Agent (the “Offering”); and

(b) the Offering is not subject to any minimum subscription level, and therefore, any funds invested are available to the Corporation and will be paid to the Corporation on the Closing Date; and

(c) the Debentures will be duly and validly created and issued pursuant to, and the conversion thereof shall be governed by, the terms and conditions of a trust indenture (the “Indenture”) to be dated the Closing Date between the Corporation and CIBC Mellon Trust Company, as trustee, which Indenture shall include the following terms:

(i) the Debentures will be limited in the aggregate principal amount to $30,000,000 (U.S.). The Corporation may, however, from time to time, without the consent of the holders of the Debentures, issue additional debentures in addition to the Debentures offered hereby;

The first payment will include accrued and unpaid interest for the period from the Closing Date to February 10, 2005. The interest on the Debentures will be payable in lawful money of the United States of America. The principal amount of the Debentures will also be payable in lawful money of the United States of America;

(iv) the Debentures will be direct obligations of the Corporation and will not be secured by any mortgage, pledge, hypothec or other charge and will be subordinated to all existing senior secured and unsecured indebtedness of the Corporation. In addition, the Indenture will not restrict the Corporation from incurring additional indebtedness for borrowed money or for mortgaging, pledging or charging its properties to secure any indebtedness;

(v) the Debentures will be convertible at the option of the holder into fully paid and non-assessable common shares of the Corporation (the “Underlying Shares”) at any time prior to 5:00 p.m. (Toronto time) on the business day prior to the maturity date, being the date that is five years and one (1) day subsequent to the Closing Date, at an initial conversion price of $4.62 (U.S.) ($5.75 (Canadian)) per Underlying Share (the “Conversion Price”), being an initial conversion rate of approximately 216 Underlying Shares per $1,000 (U.S.) principal amount of Debentures.

Holders converting their Debentures shall be entitled to receive, in addition to the applicable number of Underlying Shares, accrued and unpaid interest in respect thereof for the period up to the date of conversion from the date of the latest interest payment date on the Debentures;

(vi) the Debentures will be redeemable by the Corporation, in whole, or from time to time in part, at any time after the second anniversary of the Closing Date, on at least 30 days notice, at a redemption price equal to 100% of the principal amount plus accrued and unpaid interest, provided that the volume weighted average trading price (as calculated in accordance with the Indenture) of the Underlying Shares on the Toronto Stock Exchange for at least 20 trading days in any consecutive 30 day period ending five trading days prior to the date on which notice of redemption is given exceeds $7.50 (Canadian); and

(d) the Indenture shall otherwise be in such form and contain such terms as shall be approved by the Corporation and the Agent; and

(o) it understands and acknowledges that the certificates representing the Debentures and the Underlying Shares, in addition to bearing the foregoing legends, will bear a legend that the securities cannot be traded through the facilities of stock exchanges in Canada since the certificate is not freely transferable and consequently is not “good delivery” in transactions on such stock exchanges unless on or prior to such trade, arrangements have been made to remove the legends as provided in the provisos of paragraph 3(n) hereof, and it acknowledges that such stock exchanges would deem the selling security holder to be responsible for any loss incurred on a sale made by such security holder in such securities; and

Resale Commitments

4. The Corporation will use its reasonable commercial efforts to either: (i) file a registration statement (the “Registration Statement”) on proper form with the United States Securities and Exchange Commission (the “SEC”) covering the resale of all Underlying Shares that are restricted under the U.S. Securities Act, (ii) obtain an SEC no-action letter to permit resales of the Underlying Shares through the facilities of the Toronto Stock Exchange, within 120 days of the Closing Date, or (iii) provide a legal opinion of U.S. counsel satisfactory to the Agent regarding the ability of subscribers to resell the Underlying Shares without undue restrictions. If the Corporation does not receive the SEC no-action letter or the Agent does not receive a satisfactory legal opinion as provided in (ii) and (iii) above, respectively, the Corporation shall use its reasonable commercial efforts to cause the Registration Statement to be declared effective as soon as possible. The Corporation shall cause the Registration Statement to remain effective until the earlier of (i) 30 days after all the Debentures have been converted into Underlying Shares, or (ii) one year from the Closing Date.

5. The Indenture pursuant to which the Debentures will be issued will provide for the provisions set forth in this Section 5. If the Corporation does not receive the SEC no-action letter or the Agent does not receive a satisfactory legal opinion as provided under Section 4 above and if the Registration Statement is not declared effective within four months from the Closing Date, the conversion price of the Debentures shall be reduced to $4.54 (U.S.) ($5.65 (Canadian)). If the Registration Statement is not declared effective within six months from the Closing Date, the conversion price of the Debenture shall be reduced to $4.46 (U.S.) ($5.55 (Canadian)). If the Registration Statement is not declared effective within eight months from the Closing Date, the conversion price of the Debentures shall be reduced to $4.38 (U.S.) ($5.45 (Canadian)). The Corporation cannot assure that the Registration Statement will be declared effective by the SEC or that an SEC no-action letter or satisfactory legal opinions can be obtained. Accordingly, the foregoing shall constitute the sole remedy of subscribers for failure to effect the Registration Statement or obtain an SEC no-action letter or opinions.

6. The Subscriber acknowledges and agrees that, if it chooses to avail itself of the use of the Registration Statement it will, upon request of the Corporation, timely furnish to the Corporation for use and publication in the Registration Statement all selling

8

shareholder information required to be included in the Registration Statement, and the Subscriber will advise the Corporation whenever such information is incorrect and will furnish updated information. The Subscriber acknowledges that failure to timely provide such information, and to keep such information updated, will excuse the Corporation from maintaining or filing the Registration Statement for the benefit of such Subscriber.
