Additionally, the Company is exempt from obtaining minority shareholder approval in connection with the Debenture Conversion in reliance on section 5.7(1)(b) of MI 61-101 as, in addition to the foregoing, (i) neither the fair market value of the Common Shares issuable to insiders in connection with the Debenture Conversion nor the consideration received in respect thereof from insiders exceeds CDN$2.5 million, (ii) the Company has one or more independent directors in respect of the Debenture Conversion who are not employees of the Company, and (iii) all of the independent directors have approved the Debenture Conversion.

Furthermore, the previously announced insider private placement subscription also constitutes a "related party transaction."
