                    depot et placement du Quebec ("Caisse") dated June 14, 1985
                    under which each of SGF and Caisse has (i) agreed, inter
                    alia, to vote its shares in favor of the election to the
                    board of directors of Domtar Inc. of a number of
                    representatives of SGF and Caisse and (ii) granted a right
                    of first refusal to Caisse or SGF, as the case may be, with
                    respect to the sale of its last 7,400,000 Common Shares of
                    Domtar Inc. On December 9, 2002, Caisse granted to SGF a
                    waiver of its right of first refusal with respect to SGF's
                    last 7,400,000 Shares of Domtar Inc., which waiver will

                    granted to Caisse a waiver of its right of first refusal
                    with respect to the last 7,400,000 Common Shares of Domtar
                    Inc. held by Caisse, which waiver will expire on the

                    approximately 14.8% of the outstanding Common Shares of
