NEWS RELEASE

For Immediate Release

                 WEYERHAEUSER SENDS LETTER TO WILLAMETTE BOARD

FEDERAL WAY, Wash., February 22, 2001 - Weyerhaeuser Company (NYSE: WY) today
sent the following letter in response to a letter it received from Willamette
Industries, Inc. (NYSE: WLL):



          February 22, 2001

          Board of Directors
          Willamette Industries, Inc.
          1300 Southwest Fifth Avenue
          Portland, Oregon 97201


          Dear Willamette Board Members:

          We received your letter of February 22, and must respond since your
          letter expresses some serious misperceptions about Weyerhaeuser and
          our proposed combination with Willamette Industries.

          You are correct in assuming that the Weyerhaeuser board unanimously
          supports a combination with Willamette. This combination is too
          compelling to ignore, and our two companies are a perfect fit. Our
          board is fully informed and regularly reviews media coverage as well
          as research reports from independent financial analysts. Contrary to
          your assertions, there is extensive third-party support in the
          financial community for this combination.

          As you know, as of February 1, the last expiration date of
          Weyerhaeuser's $48 per share tender offer, your shareholders had
          tendered 51% of Willamette's outstanding common stock. Our all cash
          premium offer for 100% of the shares simply cannot be characterized
          as "coercive." What is coercive is preventing shareholders from
          taking advantage of our offer by refusing to lift your "poison pill"
          rights plan and other defensive measures as well as failing to
          schedule your annual meeting. Despite these defensive measures,
          Willamette shareholders will have the opportunity to take meaningful
          action to advance this proposed transaction by electing our director
          nominees at the annual meeting.

                                   - more -





                                     - 2 -

          Your description of Weyerhaeuser's approach as antagonistic is
          surprising. We have reviewed our public comments, and have found
          that they have, repeatedly, addressed the strength of Willamette's
          management team, the complementary asset fit, and the benefits of
          creating the premier forest products company through a combination
          of our two companies.

          We do not understand your claim that our call to negotiate is
          somehow illogical. We are confident that your shareholders see the
          logic in Willamette sitting down with Weyerhaeuser. Provided
          additional value was demonstrated, negotiation could result in an
          increased price for your shareholders. If, as you say, you are
          "committed to delivering value" we stand ready to negotiate.

          Sincerely,

          /s/ Steven R. Rogel

          Steven R. Rogel
          Chairman, President and Chief Executive Officer

FORWARD-LOOKING STATEMENTS

This news release contains statements concerning the company's future results
and performance that are forward looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Any such forward looking
statement made by Weyerhaeuser with respect to the Willamette tender offer is
not entitled to the benefit of the safe harbor protections of the Private
Securities Litigation Reform Act of 1995. The accuracy of such forward looking
statements is subject to a number of risks, uncertainties and assumptions that
may cause actual results to differ materially from those projected, including,
but not limited to, the effect of general economic conditions, including the
level of interest rates and housing starts; market demand for the company's
products, which may be tied to the relative strength of various US business
segments; performance of the company's manufacturing operations; the types of
logs harvested in the company's logging operations; the level of competition
from foreign producers; the effect of forestry, land use, environmental and
other governmental regulations; and the risk of losses from fires, floods and
other natural disasters. The company is also a large exporter and is affected
by changes in economic activity in Europe and Asia, particularly Japan, and by
changes in currency exchange rates, particularly the relative value of the US
dollar and the Euro, and restrictions on international trade. These and other
factors that could cause or contribute to actual results differing materially
from such forward looking statements are discussed in greater detail in the
company's Securities and Exchange Commission filings.
