Under the conditions specified in its Offer to Purchase dated November 16, 2005, the Maximum Principal Amount to be Accepted will, in the case of the 6.125 percent Notes due March 15, 2007, be equal to the lesser of (i) $300,000,000 and (ii) the difference between $500,000,000 (the "Tender Cap") and the principal amount of securities purchased by Weyerhaeuser pursuant to the Any and All Offers. The Maximum Principal Amount to be Accepted by Weyerhaeuser pursuant to the Maximum Tender Offers is $222,250,000. Because the principal amount of 6.125 percent Notes due March 15, 2007 validly tendered and not validly withdrawn on or before the early tender date exceeded the Maximum Principal Amount to be Accepted for the 6.125 percent Notes due March 15, 2007, Weyerhaeuser will not purchase any of its 5.950 percent Notes due November 1, 2008 in the Maximum Tender Offers. Securities of this class that have been tendered will be returned promptly to the tendering holders.

The Table below sets forth more fully the amount of securities validly tendered and accepted in the offers to date.
