NEWS RELEASE                                       [Weyerhaeuser Company logo]

FOR IMMEDIATE RELEASE

                 WEYERHAEUSER COMPANY EXTENDS TENDER OFFER FOR
              WILLAMETTE INDUSTRIES, INC. UNTIL FEBRUARY 1, 2001

FEDERAL WAY, Wash., January 5, 2001 - Weyerhaeuser Company (NYSE: WY) today
announced that it had extended its $48 per share cash tender offer for all of
the outstanding common stock of Willamette Industries, Inc. (NYSE: WLL). The
offer, which was scheduled to expire at midnight, January 4, 2001, has been
extended until 5:00 pm E.S.T. on February 1, 2001, unless further extended.

As of midnight on January 4, 2001, Willamette shareholders had tendered and
not withdrawn 52,447,805 shares pursuant to Weyerhaeuser's tender offer. This
represents approximately 48% of Willamette's total outstanding common shares.

Steven R. Rogel, chairman, president, and chief executive officer of
Weyerhaeuser, stated, "Despite the poison pill and other obstacles to
purchasing shares that the Willamette board has put in place, we were very
pleased with the level of support we received in the initial tender period. We
believe that Willamette shareholders want Willamette to negotiate a mutually
beneficial transaction with Weyerhaeuser. We hope the Willamette board will
listen to what its shareholders are saying - this transaction is too
compelling to ignore."

Weyerhaeuser Company, one of the world's largest integrated forest products
companies, was incorporated in 1900. In 1999, sales were $12.3 billion. It has
offices or operations in 13 countries, with customers worldwide. Weyerhaeuser
is principally engaged in the growing and harvesting of timber; the
manufacture, distribution and sale of forest products; and real estate
construction, development and related activities. Additional information about
Weyerhaeuser's businesses, products and practices is available at
http://www.weyerhaeuser.com.

Morgan Stanley Dean Witter is acting as Dealer Manager for the offer, and
Innisfree M&A Incorporated is acting as Information Agent.

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. 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.
