These slides include "forward-looking statements" that express expectations of
future events or results. All statements based on future expectations rather
than on historical facts are forward-looking statements that involve a number
of risks and uncertainties, and Weyerhaeuser Company ("Weyerhaeuser") cannot
give assurance that such statements will prove to be correct. Any such

MARKET EXPERT VIEWS ON VALUE (1)
-----------------------------------------------------------------------------

CHIP DILLON, SALOMON SMITH BARNEY, 5/7/01
"[W]e maintain that Weyerhaeuser ultimately would pay in the low-to-mid $50s."

MARK WILDE, DEUTSCHE BANK ALEX BROWN, 5/7/01
"If there's a deal, it looks like low/mid $50."

ANNA TORMA, MERRILL LYNCH, 12/15/00
"Although we expect that this acquisition will ultimately be accomplished,
Willamette's refusal to negotiate will likely delay any transaction. We
believe Weyerhaeuser may need to pay between $52-$54 a share to acquire
Willamette."

DON ROBERTS, CIBC WORLD MARKETS, 12/13/00
"In our opinion, the highest acceptable limit on any revised bid would be
$50.50/share."

STEVEN CHERCOVER, D.A. DAVIDSON, 12/13/00
"[W]e expect a transaction to occur in the low $50s range."

TERRY SCHUMACHER, FIRST SECURITY VAN KASPER, 11/17/00
"We still consider $52 per share to be a reasonable value for the company in
an acquisition. We note that the all-time record high for the stock was
$52 1/8 in mid-1999."

SENIOR MANAGEMENT AND BOARD ENTRENCHMENT
-----------------------------------------------------------------------------

     o    Willamette Board and Management have never tried to inform
          themselves on the Weyerhaeuser offer

          o    Refusal to engage in meaningful dialogue

     o    Willamette has never indicated how or when they will generate value
          equal to Weyerhaeuser's premium offer

     o    Active and emotional entrenchment

          o    Change-in-control agreements

          o    Incitement of employees and local constituencies

     o    Despite the fact that Willamette shareholders have endorsed the
          Weyerhaeuser proposal, the Willamette Board has continued to ignore
          the wishes of its shareholders


                                                                            16

MARKET VIEWS ON WILLAMETTE SENIOR MANAGEMENT AND BOARD ENTRENCHMENT (1)
-----------------------------------------------------------------------------
MARK CONNELLY, CREDIT SUISSE FIRST BOSTON, 5/10/01
"The absence of a cogent, economically-based response to the Weyerhaeuser bid
is both troubling and disappointing. Willamette seems to be saying "we're
worth a lot more, but we can't think of a way to explain why in a manner that
you will understand". A counter-bid from management would make sense if the
value is there; we haven't seen one."

GUY WYSER-PRATTE, WYSER-PRATTE MANAGEMENT, INC., 3/16/01
"From all indications, it seems that the majority of the Willamette's
shareholders want to accept a premium offer for their shares, and want you and
your board to maximize shareholder value. I note that more than half of
Willamette's shares have been tendered into Weyerhaeuser's tender offer. Yet
Willamette has chosen to ignore the wishes of the majority and force its
shareholders into a proxy fight."

THE PORTLAND BUSINESS JOURNAL, 3/9/01
"Willamette's management team is acting like it has been living in the woods
the last century. Have any of its directors heard of shareholder rights? How
about fiduciary responsibility? Or just plain common sense? The directors seem
to be completely lacking in the latter... Willamette's Board has apparently
forgotten that when you go to the public for money, you become responsible to
the public for your actions... sometimes the financial interests of the
shareholders supercedes the job-security interests of the members of
Management and the Board."

MONEY MANAGER QUOTED IN BRAINSTORM NW MAGAZINE, MAY 2001
"What is unreasonable is that Willamette has not suggested a price. They make
light of how shareholders have been voting. After all, 51 percent of the stock
has at one point been offered - and of the remaining shares, 20 to 30 percent
of them are tied to people who are family insiders. So don't tell me people
don't support this bid - they do."

PROXY VOTE IS ABOUT BOARD ACCOUNTABILITY
-----------------------------------------------------------------------------

     o    Vote is about electing directors who:

          o    Will listen to shareholders

          o    Believe their duty is to maximize shareholder value

     o    Weyerhaeuser nominees

          o    Experienced business people

          o    Committed to maximizing value for ALL Willamette shareholders


                                                                            18

WHY WE ARE ASKING FOR YOUR SUPPORT
-----------------------------------------------------------------------------

     o    Weyerhaeuser nominees are committed to implementing a value
          maximizing process for all Willamette shareholders

     o    Independent financial analysts have indicated that absent
          Weyerhaeuser's offer, the value of Willamette shares could fall
          significantly

          o    "Downside risk could be as much as $33 per share if the deal
               with Weyerhaeuser falls through" - Peter Ruschmeier, Lehman
               Brothers, 4/16/01 (1)
     ---------------------------------------------------------------------
    |o    If the Weyerhaeuser nominees are not elected, Weyerhaeuser will |
    |     withdraw its offer                                              |
