NEWS RELEASE

For Immediate Release

             WEYERHAEUSER SENDS LETTER TO WILLAMETTE SHAREHOLDERS


FEDERAL WAY, Wash., May 29, 2001 - Weyerhaeuser Company (NYSE: WY) today
announced that it sent the following letter to shareholders of Willamette
Industries, Inc. (NYSE: WLL):



         May 25, 2001

         Dear Willamette Shareholder:


         At Willamette's long-delayed Annual Meeting on June 7th, you will
         have an opportunity to send a message to the Willamette board that
         they cannot ignore by electing directors who are committed to
         maximizing value for shareholders NOW. We believe the only way to
         facilitate the proposed combination is to vote the GOLD proxy card
         FOR the election of the Weyerhaeuser nominees.


              INSTITUTIONAL SHAREHOLDER SERVICES (ISS) AND PROXY
              MONITOR RECOMMEND WILLAMETTE SHAREHOLDERS VOTE FOR
                           THE WEYERHAEUSER NOMINEES


         ISS and Proxy Monitor, the nation's leading independent proxy
         advisory firms, recommended that Willamette shareholders vote FOR
         the Weyerhaeuser slate of director nominees at Willamette's Annual
         Meeting scheduled for June 7, 2001. Their recommendations are
         relied upon by hundreds of major institutional investment firms,
         mutual funds, and other fiduciaries throughout the country.

          In connection with its recommendation, ISS noted in its May 22,
2001 report that:

               "Metrics aside, it is Willamette's stonewalling that has kept
               Weyerhaeuser from improving its bid."

               "Weyerhaeuser, understandably, does not wish to keep bidding
               against itself, but has stated its willingness to raise its
               offer if Willamette will only negotiate . . . The issue in this
               proxy contest is thus not about the price on offer, it is about
               getting ANY price."

               "We believe management has made its position abundantly clear:
               it is simply not interested in selling. But in remaining
               unyielding towards negotiating with Weyerhaeuser, Willamette
               has shown a high degree of disregard for the wishes of its own
               shareholders, as expressed in their response to the tender
               offer."

                                    -more-






                                      -2-

               "In the face of the company's takeover defenses, we believe
               that shareholders desirous of obtaining any deal--be it with
               Weyerhaeuser or another party--have no other recourse than to
               elect the Weyerhaeuser nominees."*

         In its May 24, 2001 recommendation Proxy Monitor stated that:

               "[O]ne has to wonder whether the Willamette board would accept
               ANY offer from Weyerhaeuser, or any other suitor for that
               matter. Management has consistently refused to negotiate with
               Weyerhaeuser, has not given any indication of a price it might
               accept, and has not looked for other buyers. Instead, the
               board's strategy seems to be concentrated upon its own
               survival."

               "[T]he Willamette board appears to have lost sight of the
               fiduciary responsibility it owes to its shareholders and, for
               that reason, its credibility as well."

               "Willamette's agreement with its financial advisor in this
               contest, Goldman Sachs & Co., is eye-popping as well."*

         Ask yourself why Willamette is paying Goldman Sachs $30 million of
         your money to prevent a deal with Weyerhaeuser.



                IF THE WEYERHAEUSER NOMINEES ARE NOT ELECTED WE
                            WILL WITHDRAW OUR OFFER


         If the Weyerhaeuser slate is elected at the June 7th meeting and
         Willamette continues to refuse to negotiate, we intend to nominate
         a slate of directors for election at Willamette's 2002 Annual
         Meeting. HOWEVER, IF THE WEYERHAEUSER NOMINEES ARE NOT ELECTED ON
         JUNE 7TH, WE WILL WITHDRAW OUR OFFER, SINCE IT WILL TAKE AT LEAST
         TWO MORE YEARS, UNTIL THE 2003 ANNUAL MEETING, TO EFFECT A
         TRANSACTION NOT APPROVED BY THE CURRENT WILLAMETTE BOARD.



                    SEND A MESSAGE TO THE WILLAMETTE BOARD
                         DON'T DELAY--VOTE GOLD TODAY


         We believe you deserve a board of directors that will act to
         protect your interests. We are seeking your support for the
         election of our three nominees to Willamette's board at the
         Willamette Annual Meeting. Please vote FOR the election of the
         Weyerhaeuser nominees on your GOLD proxy card.

         Very truly yours,

         /s/ Steven R. Rogel
         Steven R. Rogel
         Chairman, President and Chief Executive Officer
