NEWS RELEASE

For Immediate Release


             ISS RECOMMENDS THAT WILLAMETTE SHAREHOLDERS VOTE FOR
                             WEYERHAEUSER NOMINEES


FEDERAL WAY, Wash., May 22, 2001 - Weyerhaeuser Company (NYSE: WY) today
announced that Institutional Shareholder Services (ISS) recommended that
Willamette Industries, Inc. (NYSE: WLL) shareholders vote FOR the Weyerhaeuser
slate of director nominees at Willamette's Annual Meeting scheduled to be held
on June 7, 2001.

ISS is widely recognized as the leading independent proxy advisory firm in the
nation. Their recommendations are relied upon by hundreds of major
institutional investment firms, mutual funds, and other fiduciaries throughout
the country.


In reaching its decision to recommend that Willamette shareholders vote FOR
the three Weyerhaeuser nominees over the Willamette slate, 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 [Willamette's] 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.


          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."*

                                      -2-


Steven R. Rogel, chairman, president, and chief executive officer of
Weyerhaeuser, said, "We are very pleased that ISS has recommended that
Willamette shareholders vote for the Weyerhaeuser director nominees. We
believe that the current Willamette board will not sell the company at any
price. At Willamette's June 7th Annual Meeting, shareholders will have the
opportunity to send a message to the Willamette board that cannot be ignored.
Shareholders will be able to elect directors who are committed to maximizing
value for shareholders now."


Weyerhaeuser is seeking the support of Willamette shareholders for the
election of the three Weyerhaeuser nominees to Willamette's board at the
Willamette Annual Meeting. We urge Willamette shareholders to sign, date and
return the GOLD proxy card today voting FOR the election of the Weyerhaeuser
nominees. For more information about how to vote for the Weyerhaeuser slate of
director nominees, shareholders can call Weyerhaeuser's proxy solicitor,
Innisfree M&A Incorporated, at 1-877-750-5838 (toll-free).

companies, was incorporated in 1900. In 2000, sales were $16 billion. It has

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 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.
