Montreal, Quebec, Canada, 04 April 2007 -- /PRNewswire/ -- Domtar Corporation (NYSE/TSX: UFS) today announced that Domtar Inc., one of its principal operating subsidiaries, has commenced a change of control offer for all USD 125,000,000 outstanding principal amount of its 9-1/2% Debentures Due 2016 (CUSIP Number: 257561AT7).

This offer is being made solely to fulfill Domtar Inc.'s obligations under the indenture governing the debentures, which requires that Domtar Inc. make an offer to purchase the debentures following a "change of control triggering event" (as defined in the indenture). A "change of control triggering event" occurred on 07 March 2007, as a result of (i) a person becoming the holder of more than 35% of the outstanding common shares of Domtar Inc. pursuant to the combination of the fine paper business and related assets of Weyerhaeuser Company with Domtar Inc. and (ii) a rating decline within 90 days after the public announcement of such transactions as a result of a change in methodology by Moody's Investor Services for rating North American forest product companies.

As required by the indenture, the purchase price for each USD 1000 principal amount of debentures tendered and accepted for payment pursuant to the offer is USD 1010, which is equal to 101% of the principal amount of the debentures, plus accrued and unpaid interest on the principal amount tendered to, but not including, the payment date.

The offer will expire at 12:00 midnight, Eastern Time, on 04 May 2007, unless extended or earlier terminated. The terms and conditions of the offer, including the conditions to Domtar's obligation to accept the debentures tendered and pay the purchase price for them, are set forth in a Notice of Change of Control and Offer to Purchase dated 04 April 2007.

For information regarding the change of control offer, please contact Georgeson Inc., the information agent for the offer, at 1-800-445-1790 (toll free) or 212-440-9800.
