May 7, 2002

Dear Potlatch Corporation Stockholder:

At next week’s annual meeting, Potlatch Corporation will ask its stockholders to approve a proposal to decrease the number of seats on the company’s board of directors from a range of nine to 21 to a range of seven to 15. Because decreasing the size of the board represents an amendment to the company’s Restated Certificate of Incorporation, the proposal requires approval from holders of 80% of the company’s outstanding common stock in order to pass.

Your company urges you to support this amendment by voting FOR Proposal 2 on your proxy card. We believe a smaller board will be both more efficient and more effective. We also note that the overall trend in corporate governance practice is toward smaller boards as a means of promoting dialogue among directors.

In addition, we urge stockholders to vote FOR management’s slate of directors and FOR the ratification of auditors (Proposal 1 and Proposal 4, respectively). On Proposal 3, the stockholder proposal calling for a special report on dividend policy, management recommends a vote AGAINST.

You should know that Institutional Shareholder Services (ISS), an independent proxy advisory firm, has recommended that Potlatch Corporation stockholders support company management by voting FOR Proposals 1, 2 and 4, and AGAINST Proposal 3 at the annual meeting.

Your vote is important, so please mark, sign, date and return the enclosed proxy card in the envelop provided. If you need assistance voting your shares, you are encouraged to call D.F. King & Co., Inc., which is assisting Potlatch Corporation, toll-free on 1-800-714-3306. The annual meeting of Potlatch Corporation stockholders is May 15, so please act today.

Notice to Proxy Analysts

Voting Shares of

Potlatch Corporation

Potlatch Corporation will host its Annual Meeting on May 15. Due to the company’s use of time-phased voting, investors holding stock in “Street name” WILL NOT be able to vote through ADP Proxy Services by telephone, Proxy Edge or internet.

Proposal 2 on the agenda for the meeting is a proposal to amend the company’s Restated Certificate of Incorporation to decrease the size of the board of directors. An affirmative vote from stockholders owning 80% of the shares outstanding is required to pass the proposal. Accordingly, a failure to vote will have the same effect as a vote against adoption of the proposal.

The Company’s Board is recommending stockholders vote as follows:

FOR Proposal 1 on the election of directors

FOR Proposal 2 to decrease the size of the board of directors

AGAINST Proposal 3 urging preparation of a dividend policy report

FOR Proposal 4 on the ratification of auditors

ISS supports the Board’s recommendations on all proposals.

The meeting is scheduled to be held early next week! To ensure that your vote is counted, please return your voting instructions to ADP Proxy Services in time for required processing and forwarding by ADP to the Company.

If you need assistance in voting your shares, please call D. F. King & Co., Inc. at 800-714-3306.
