NEWS RELEASE

For Immediate Release

     WEYERHAEUSER SENDS LETTER TO WILLAMETTE SHAREHOLDERS

FEDERAL WAY, Wash., March 27, 2001 - Weyerhaeuser Company (NYSE: WY) today
announced that it sent the following letter to shareholders of Willamette
Industries, Inc. (NYSE: WLL):

March 26, 2001


Dear Willamette Shareholder:


     As you know, Weyerhaeuser, one of the world's leading forest products
companies, has commenced a tender offer to acquire all of the outstanding
shares of Willamette Industries for $48.00 per share in cash. Despite
Weyerhaeuser's numerous attempts to negotiate a mutually beneficial
transaction, the Willamette board of directors continues to refuse to sit down
with us. After considerable delay, the Willamette board has scheduled the
company's annual meeting of shareholders for June 7, 2001. Your voice in
governing the company can now be heard. WE BELIEVE THAT IN ORDER TO PROTECT
THE VALUE OF YOUR INVESTMENT IN WILLAMETTE, YOU SHOULD SIGN, DATE AND RETURN
THE ENCLOSED GOLD PROXY CARD TO VOTE FOR THE ELECTION OF THE WEYERHAEUSER
NOMINEES TODAY.

                           IT ALL COMES DOWN TO VALUE

     The Weyerhaeuser offer will provide you with a substantial premium for
your shares. Based on Willamette's closing share price on Friday, November 10,
2000, the last trading day prior to Weyerhaeuser's announcement of our
proposal, the Weyerhaeuser offer represents a premium of approximately 38
percent. It is also a substantial premium of approximately 60 percent to
Willamette's average share price for the 60 days prior to the announcement.

     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:

     o    our 38 percent premium exceeds the average premium for the 64 paper
          industry company transactions that have occurred since 1990(1); and

     o    since we announced our offer, the S&P paper and forest products
          index (as opposed to Willamette's self-selected "relevant composite
          of forest products company stocks") increased by only 4.1 percent(2)
          and in the last 10 trading days has declined by 12.6 percent.(3)

     Notwithstanding that our $48 per share all cash offer would provide you
with a significant and immediate premium, your board and management have not
disclosed any strategic initiatives that we believe could reasonably be
expected to provide you with greater or even comparable value.

                                       -2-



     According to its amended preliminary proxy statement, Willamette
"believe[s its] strategic plan will continue to deliver greater value than the
Weyerhaeuser offer."(4) HOWEVER, WILLAMETTE'S TOTAL SHAREHOLDER RETURN FOR THE
LAST FOUR YEARS, ASSUMING THE REINVESTMENT OF DIVIDENDS, HAS AVERAGED ONLY 1.9
PERCENT ON AN ANNUALIZED BASIS(5) -- FAR BELOW THE SIGNIFICANT PREMIUM OUR
OFFER WOULD DELIVER TO YOU NOW.

     We believe our all cash offer is even more attractive given today's
uncertain marketplace. Industry conditions are weakening. Willamette's
chairman, William Swindells, has acknowledged the "significant challenges of
[the] current environment, including economic slowdown, rising energy costs
and weakening industry conditions."(6)

     We have made it clear and repeat here again that if Willamette can
demonstrate additional value, Weyerhaeuser stands ready to negotiate.


                            THE WEYERHAEUSER NOMINEES
                      WILL WORK TO MAXIMIZE YOUR INVESTMENT

     The Weyerhaeuser nominees are experienced business people and none of
them is employed by Weyerhaeuser. If elected, the nominees will receive from
Willamette the same compensation as all other Willamette directors. Each of
these nominees will have a fiduciary duty to act in the best interests of
Willamette and its shareholders and will seek to maximize the value of your
investment in Willamette. The nominees believe that you - the owners of
Willamette - are entitled to determine the future of your investment.


     We urge you to ignore Willamette's rhetoric and focus on what we believe
this election is really about:


     o    electing directors who believe their duty is to MAXIMIZE THE VALUE
          OF YOUR WILLAMETTE SHARES;

     o    electing directors who will best PROTECT THE VALUE OF YOUR INVESTMENT
          IN WILLAMETTE; and

     o    electing directors who believe that YOU--THE OWNERS OF WILLAMETTE--are
          entitled to decide whether or not to accept the Weyerhaeuser offer.

     We believe that the election of our director nominees is critical to the
completion of a transaction with Weyerhaeuser. ASK YOURSELF: "HOW MUCH WILL MY
INVESTMENT IN WILLAMETTE BE WORTH ABSENT THE WEYERHAEUSER OFFER?"

     WE BELIEVE THAT YOU DESERVE A BOARD OF DIRECTORS THAT IS RESPONSIBLE TO
YOU AND WILL ACT IN YOUR BEST INTERESTS. WE ARE SEEKING YOUR SUPPORT FOR THE
ELECTION OF OUR THREE NOMINEES TO WILLAMETTE'S BOARD AT THE WILLAMETTE ANNUAL
MEETING. PLEASE SIGN, DATE AND RETURN THE ENCLOSED GOLD PROXY CARD VOTING FOR
THE ELECTION OF THE WEYERHAEUSER NOMINEES.

delivering your proxy, please call our proxy solicitor, Innisfree M&A
Incorporated, at 1-877-750-5838.

Very truly yours,

/s/ STEVEN R. ROGEL

Steven R. Rogel
Chairman, President and Chief Executive Officer

FOR the election of the Weyerhaeuser nominees by signing, dating and returning
the enclosed GOLD proxy card in the postage-paid envelope TODAY.
