                PLUM CREEK TIMBER COMPANY AND THE TIMBER COMPANY
            TO PROCEED WITH MERGER BASED ON OPINIONS FROM TAX COUNSEL

            COMPANIES SET PRELIMINARY DATES FOR SHAREHOLDERS MEETINGS

SEATTLE AND ATLANTA - JUNE 12, 2001- Plum Creek Timber Company, Inc. (NYSE: PCL)
and Georgia-Pacific Corporation (NYSE: GP) have amended their merger agreement
and are proceeding with the previously announced merger of Plum Creek and The
Timber Company (NYSE: TGP).

The decision to move forward was made by the boards of directors of Plum Creek
and Georgia-Pacific following confirmation that they will receive opinions from
tax counsel that the spin-off of The Timber Company from Georgia-Pacific and the
subsequent merger with Plum Creek will be tax-free to both companies and their
shareholders. The outside legal opinions from independent tax counsel to each
company (Skadden, Arps, Slate, Meagher & Flom LLP, and McDermott, Will & Emery)
would replace a private letter ruling previously requested from the Internal
Revenue Service.

Plum Creek and The Timber Company plan to hold shareholder meetings on August
15, 2001, to approve the transaction. Closing is expected by the end of
September 2001.

The IRS has notified the companies that it decided not to issue the private
letter ruling because its standard for proving the business purpose for such a
ruling had not been met. This high burden of proof, which is more stringent than
applicable legal standards, pertains only to advance rulings. Based on
discussions with the IRS and the advice of legal counsel, the companies believe
the transaction will not be taxable. As an added





measure to reduce uncertainty concerning any possible tax risks, the companies
will obtain up to $500 million in tax liability insurance.

"Plum Creek and Georgia-Pacific have taken action enabling us to move into the
final phase of completing this important strategic transaction," said Plum Creek
President and CEO Rick R. Holley. "We are highly confident of our position,
based on our discussions with the IRS and on the opinions we will receive from
tax counsel, that the transaction will be tax-free to all parties. We have used
the past several months productively, and our initial work with our new partners
has reinforced our confidence that the new Plum Creek will have the scope of
resources, scale, structure and combined management capabilities to generate
increasing value for the shareholders of the combined company."

Following the merger, Plum Creek will be the second largest private timberland
owner in the United States, with more than 7.8 million acres of timberlands
located in 19 states.

A.D. "Pete" Correll, Chairman and Chief Executive Officer of Georgia-Pacific,
said, "This transaction creates significant value for both companies and their
shareholders. The opinions of our tax counsel are clear and unambiguous. We
believe the opinions of our tax counsel carry sufficient weight for us to move
forward with our plans for delivering the value from this transaction, divesting
our timberland ownership and continuing to reduce our overall corporate debt."

The financial terms of the agreement remain essentially the same. The Timber
Company shareholders will receive 1.37 shares of Plum Creek stock for each share
of The Timber Company stock. Based on Plum Creek's closing stock price of $28.11
on June 11, 2001, the overall transaction is valued at approximately $3.8
billion, including an estimated $730 million of The Timber Company debt that
Plum Creek will re-finance at closing.

Both companies will now seek the approval of the merger from their respective
shareholders. Proxy statements describing the transaction in detail will be
mailed promptly to shareholders of The Timber Company and Plum Creek.

Plum Creek, a real estate investment trust, is one of the largest land owners in
the nation, with timberlands in the Northwest, Southern, and Northeast regions
of the United States and nine wood product mills in the Northwest.

Headquartered at Atlanta, The Timber Company is a separate operating group of
Georgia-Pacific and its performance is reflected in one of the corporation's two
common stocks. The Timber Company manages 4.7 million acres of timberland in the
United States and sells timber and wood fiber to industrial wood users.

CONFERENCE CALL TODAY: Plum Creek President and CEO, Rick R. Holley, will host a
conference call for analysts and investors Tuesday, June 12, at 5:00 PM EDT. The
call-in number is: 800 606-8940
