NEWS RELEASE

For Immediate Release

             WEYERHAEUSER SENDS LETTER TO WILLAMETTE SHAREHOLDERS

FEDERAL WAY, Wash., February 28, 2001 - Weyerhaeuser Company (NYSE: WY) today
announced that it sent the following letter to shareholders of Willamette
Industries, Inc. (NYSE: WLL):

          February 27, 2001

          Dear Willamette Shareholder:

          As you know, Weyerhaeuser, one of the world's leading forest
          products companies, has made an offer to acquire all the outstanding
          shares of Willamette Industries for $48.00 per share in cash. Our
          offer represents a 38% premium over Willamette's closing share price
          on November 10, 2000, the last trading day before our offer was
          announced, and a premium of approximately 60% to the average share
          price for the 60 days prior to November 10, 2000. Despite the fact
          that, as of February 1, 2001, a majority of Willamette shares had
          been tendered into our offer, the Willamette board of directors
          refuses to negotiate a mutually beneficial transaction. In addition,
          the Willamette board has delayed the date of Willamette's 2001
          annual meeting of shareholders so that your voices in governing the
          company cannot be heard. WE URGE YOU TO PROTECT THE VALUE OF YOUR
          INVESTMENT IN WILLAMETTE BY SIGNING, DATING AND RETURNING THE
          ENCLOSED GOLD PROXY CARD TO VOTE FOR THE ELECTION OF THE
          WEYERHAEUSER NOMINEES TODAY.

                     OUR $48 PER SHARE CASH OFFER PROVIDES
               SUPERIOR VALUE TODAY FOR WILLAMETTE SHAREHOLDERS

          We believe our offer provides greater value than Willamette can
          generate as a stand-alone company. Contrary to Willamette's
          selective analysis of purportedly comparable transactions, our
          premium is considerably higher than an average of prior transactions
          in the forest products industry. In fact:

          -    our 38% premium exceeds the average premium for the 64 paper
               industry company transactions that have occurred since 1990 (1)
          -    since we announced our offer, the S&P paper and forest products
               index (2) (as opposed to Willamette's self-selected "relevant
               composite of forest products company stocks") increased by
               only 4.3% (3)
          -    while no one can accurately predict future stock prices, an
               independent financial analyst has suggested that if
               Weyerhaeuser's bid is withdrawn, "THE DOWNSIDE IN WILLAMETTE
               STOCK IS SUBSTANTIAL (AT LEAST TO THE LOW $30S, AND POTENTIALLY
               LOWER)" (4)

         (1) November 2000 presentation by Salomon Smith Barney.
         (2) Excluding Weyerhaeuser and Willamette.
         (3) Calculated from November 10, 2000 to February 20, 2001, the
             time period covered in Willamette's February 22, 2001 analysis.
         (4) Mark W. Connelly, Credit Suisse First Boston Corporation, "WLL:
             It's Not the tender--It's the Vote," January 31, 2001.

                                   - 2 -

          We are ready to deliver value to Willamette shareholders--in
          cash--as soon as the Willamette board permits its shareholders to
          accept our offer. WE HAVE ALSO MADE IT CLEAR AND REPEAT HERE AGAIN
          THAT IF WILLAMETTE CAN DEMONSTRATE ADDITIONAL VALUE, WEYERHAEUSER
          STANDS READY TO NEGOTIATE.

                  WILLAMETTE'S TACTICS ARE COSTING YOU MONEY

          Willamette's board of directors would have you believe that it
          "takes very seriously [its] fiduciary obligations". A review of the
          board's actions, however, suggests that the board has priorities
          other than the best interests of Willamette shareholders. Since the
          date our offer was announced, the Willamette board has:

          -    refused to amend its "poison pill" rights plan or take other
               steps that would permit you to accept our offer
          -    amended the company's by-laws to eliminate the company's
               traditional April annual meeting date and permit the board to
               schedule the meeting in its sole discretion
          -    failed to call the annual meeting and refused even to say when
               it will be held
          -    enhanced the "golden parachute" severance arrangements with a
               significant number of highly paid employees and established
               such arrangements with virtually all the company's salaried
               employees
          -    engaged in an active campaign of disinformation to foment
               opposition to the proposed transaction among Willamette's
               employees, customers and the communities in which the company
               operates

          While the board refuses to negotiate, the value of your shares
          continues to decrease. Since the December 6, 2000 high following our
          offer, the total market value of Willamette's shares has fallen by
          approximately $459 million, or 8.3%.

               ELECT DIRECTOR NOMINEES WHO WILL ACT IN YOUR BEST
                                   INTERESTS

          Weyerhaeuser's nominees are experienced business people with
          extensive forest products experience. None of them is currently
          employed by Weyerhaeuser. You should ignore Willamette's rhetoric
          and focus on what this election is really about:

          -    electing directors who believe their duty is to act to maximize
               the value of Willamette's shares
          -    electing directors who will best protect the value of your
               investment in Willamette
          -    electing directors who believe that the shareholders--the
               owners of Willamette--are entitled to decide whether or not to
               accept the Weyerhaeuser offer

          Although Willamette is attempting to distract you by questioning
          the ability of the Weyerhaeuser nominees to represent you,
          remember that three of the four Willamette directors up for
          re-election were not directors of public companies at the time
          they joined Willamette's board. TAKE CONTROL OF YOUR
          INVESTMENT--VOTE FOR THE ELECTION OF THE WEYERHAEUSER NOMINEES BY
          SIGNING, DATING AND RETURNING THE ENCLOSED GOLD PROXY CARD TODAY.
