 ensure a representative vote. Pursuant to the NYSE corporate governance rules we, as a foreign private issuer, have elected to comply with practices that are permitted under Canadian law in lieu of the provisions of Section 310.00. West Fraser’s by-laws provide that the quorum requirement for meetings of shareholders is a minimum of 25% of the outstanding common shares in attendance at each meeting of shareholders, which is less than the 50% majority quorum requirement of many U.S. incorporated NYSE listed issuers.

Except as stated above we are in compliance with the rules generally applicable to U.S. domestic companies listed on the NYSE. We may in the future decide to use other foreign private issuer exemptions with respect to some of the other NYSE listing requirements. Following our home country governance practices, as opposed to the requirements that would otherwise apply to a company listed on the NYSE, may provide less protection than is accorded to investors under the NYSE listing requirements applicable to U.S. domestic issuers.
