The Exchange Offer
 
The Final Exchange Ratio is 11.1442
 
The final exchange ratio in connection with the exchange offer is 11.1442 because the limit on the exchange ratio (as described below) is in effect. Accordingly, the exchange offer is mandatorily extended to 12:00 midnight, New York City time, on March 6, 2007, unless the exchange offer is voluntarily extended.
 
Weyerhaeuser Company (“Weyerhaeuser”) is offering to exchange all shares of common stock of Domtar Corporation (“Company common stock”), which are owned by Weyerhaeuser, for common shares of Weyerhaeuser (“Weyerhaeuser common shares”) and exchangeable shares of Weyerhaeuser Company Limited (“Weyerhaeuser exchangeable shares”) that are validly tendered and not properly withdrawn, as described in more detail in the exchange offer prospectus (the “Prospectus—Offer to Exchange”).  Prospectus—Offer to Exchange (PDF).

The exchange offer was designed to permit holders of Weyerhaeuser common shares and Weyerhaeuser exchangeable shares to exchange their shares for shares of Company common stock at a 10% discount to the calculated per-share value of Company common stock.  Stated another way, for each $1.00 of Weyerhaeuser common shares or Weyerhaeuser exchangeable shares accepted in the exchange offer, the terms were designed so that the tendering holder would receive approximately $1.11 of Company common stock, based on calculated per-share values, subject to (i) a limit of 11.1442 shares of Company common stock for each Weyerhaeuser common share or Weyerhaeuser exchangeable share accepted in the exchange offer and (ii) proration.
 
The final calculated per-share values were equal to (i) with respect to Weyerhaeuser common shares and Weyerhaeuser exchangeable shares, the simple arithmetic average of the “daily volume-weighted average price” (or daily VWAP) of Weyerhaeuser common shares on the New York Stock Exchange on February 28, March 1 and March 2, 2007 (the “Valuation Dates”); and (ii) with respect to Company common stock, the simple arithmetic average of the daily VWAP of common shares of Domtar Inc. on the New York Stock Exchange on each of the Valuation Dates. The limit is in effect because dividing the final calculated value of Weyerhaeuser common shares by the final per share value of Domtar Inc. results in a share exchange ratio above the limit.
 
 

 
 
Because the exchange ratio is now fixed at the limit of 11.1442 shares of Company common stock for each Weyerhaeuser common share and exchangeable share accepted for exchange, the relative values of the Company common stock exchanged for Weyerhaeuser shares will vary with the market value of Weyerhaeuser shares and the market value of Company common stock when it is distributed pursuant to the exchange offer. Accordingly, the actual market value of the shares of Company common stock exchanged for each Weyerhaeuser share may be less than $1.11 for each $1.00 of Weyerhaeuser common shares or exchangeable shares accepted in the exchange offer.
 
The information on this website is being provided solely in connection with the exchange offer and should not be used for any other purpose. You should refer to the Prospectus—Offer to Exchange for additional information about the exchange offer.

GLOSSARY
 
calculated per-share value: The calculated per-share value of a Weyerhaeuser common share or Weyerhaeuser exchangeable share for purposes of the exchange offer equals the simple arithmetic average of the “daily volume-weighted average price” of Weyerhaeuser common shares on the New York Stock Exchange on each of the Valuation Dates, as calculated by Weyerhaeuser. The calculated per-share value of a share of Company common stock for purposes of the exchange offer equals the average of the “daily volume-weighted average price” of common shares of Domtar Inc. on the New York Stock Exchange on each of the Valuation Dates, as calculated by Weyerhaeuser.  The calculated per-share values will be rounded to four decimal places.
 
daily VWAP: Daily VWAP means VWAP for the period beginning at 9:30 a.m., New York City time (or such other time as is the official open of trading on the New York Stock Exchange), and ending at 4:00 p.m., New York City time (or such other time as is the official close of trading on the New York Stock Exchange and in no event later than 4:10 p.m., New York City time), as reported to Weyerhaeuser  by Bloomberg L.P. for equity ticker WY.N in the case of Weyerhaeuser common shares, and equity ticker DTC.N, in the case of common shares of Domtar Inc. Daily VWAP will be rounded to four decimal places.
 
exchange ratio: The number of shares of Company common stock that will be exchanged for each Weyerhaeuser common share or Weyerhaeuser exchangeable share accepted in the exchange offer.  The final exchange ratio will be rounded to four decimal places.
 
indicative calculated per-share value: The indicative calculated per-share values of Weyerhaeuser common shares and Company common stock on each of the Valuation Dates shown on this website equal, with respect to each stock, (i) on the first Valuation Date, the actual VWAP that day, (ii) on the second Valuation Date, the actual VWAP that day averaged with the actual daily VWAP on the first Valuation Date and (iii) on the third Valuation Date, the actual VWAP that day averaged with the actual daily VWAP on the first Valuation Date and with the actual daily VWAP on the second Valuation Date.
 
limit: The number of shares of Company common stock each tendering Weyerhaeuser shareholder will receive is subject to a limit of 11.1442 shares of Company common stock for each Weyerhaeuser common share or Weyerhaeuser exchangeable share accepted in the exchange offer.  If the limit is in effect, you will receive less than $1.11 of Company common stock for each $1.00 of Weyerhaeuser common shares or Weyerhaeuser exchangeable shares, depending on the calculated per-share values of Weyerhaeuser common shares and Company common stock at the expiration date, and you could receive much less.  The exchange offer does not provide for a minimum exchange ratio.
 
 

 
 
proration: If the exchange offer is oversubscribed and Weyerhaeuser cannot fulfill all tenders of all Weyerhaeuser common shares and Weyerhaeuser exchangeable shares at the exchange ratio, then all Weyerhaeuser common shares and Weyerhaeuser exchangeable shares validly tendered will generally be accepted for exchange on a pro rata basis in proportion to the number of shares tendered.  We refer to this as “proration.”  Weyerhaeuser shareholders who beneficially own “odd-lots” (less than 100 Weyerhaeuser common shares or 100 Weyerhaeuser exchangeable shares) and who validly tender all their Weyerhaeuser common shares or Weyerhaeuser exchangeable shares, as the case may be, will not be subject to proration.  The examples provided in the tables on this website assume that there is no proration for non-odd-lot holders.
 
VWAP: VWAP means the “volume-weighted average price” per share of stock on the New York Stock Exchange.
