M. Nasdaq Exemptions

The rules and regulations of the Nasdaq require each listed issuer to provide that a quorum for its shareholders’ meetings be at least 33 1/3 percent of the issuer’s outstanding shares. The Registrant has been granted an exemption from this requirement because it is contrary to generally accepted business practices in Canada, the Registrant’s country of domicile. The Registrant has had the benefit of this exemption in the current and prior year.

In determining whether a requirement is contrary to generally accepted business practices, the Nasdaq rules generally look to the requirements of the primary market in the issuer’s country of domicile. The rules and policies of the Toronto Stock Exchange, the primary market in Canada, do not contain quorum requirements, and the Canada Business Corporations Act, the Registrant’s governing statute, defers to the quorum requirements contained in an issuer’s By-laws. Under the Registrant’s By-laws, a quorum for a meeting of the Registrant’s shareholders is two persons present in person, each being a shareholder entitled to vote thereat or a duly appointed proxyholder or representative for a shareholder so entitled.
