TO ALL WILLAMETTE SHAREHOLDERS:

                  NATION'S LEADING INDEPENDENT PROXY ADVISORY
                    FIRMS RECOMMEND WILLAMETTE SHAREHOLDERS
                      VOTE FOR THE WEYERHAEUSER NOMINEES

Institutional Shareholder Services (ISS) and Proxy Monitor are widely
recognized as the leading independent proxy advisory firms in the nation.
Their recommendations are relied upon by hundreds of major institutional
investment firms, mutual funds, and other fiduciaries throughout the country.

On May 22, 2001, ISS recommended that if Willamette shareholders want any
transaction, they should vote the GOLD proxy card FOR the Weyerhaeuser
nominees. 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."

        "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 said:

        "[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."*

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

If our slate is elected at the June 7th meeting and Willamette continues to
refuse to negotiate, Weyerhaeuser intends 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.

                         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.
