(1)	As previously reported, the Issuer declared a special distribution to stockholders that was payable on 3/31/2006, in cash, shares of Potlatch common stock, or a combination of both, at the election of each stockholder. Reporting person beneficially owns restricted stock units (RSUs) that may be settled for shares of common stock on a one-for-one basis. For purposes of the special distribution and in accordance with the stockholder approved 2005 Stock Incentive Plan under which the RSUs were granted, the shares of Potlatch common stock were valued for purposes of the special distribution based on the closing sales price of the stock on 3/31/2006. In addition, for the special distribution RSUs were credited 100% in common stock. The amount of shares denoted represents the total shares attributable to the reporting person in the special distribution, which includes a quarterly distribution that accrued on the RSUs prior to 2/14/2006, the record date for the special distribution.
