Forward-Looking Statement

This presentation 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. Factors listed below, as well as other factors not included, may cause our actual results to differ from our forward-looking statements. There is no guarantee that any of the events anticipated by our forward-looking statements will occur, or if they occur, what effect they will have on our operations or financial condition. We will not update our forward-looking statements after the date of this presentation. Some forward-looking statements discuss our plans, strategies and intentions. They use words such as expects, may, will believes, should, approximately, anticipates, estimates and plans. We also may use the positive or negative or a variation of those terms. We make forward-looking statements of our expectations during the third quarter 2008 regarding our markets, earnings and performance of our business segments, homebuilding starts, higher costs for energy and silvaculture, additional logging and road costs, demand and pricing for our wood products, decreased expenses for annual planned maintenance in the Cellulose Fibers segment, increases in freight charges and increases in chemical and fiber costs. We also base these statements on the expected effect of: foreign exchange rates, primarily the Euro and Canadian dollar, adverse litigation outcomes and the adequacy of reserves, regulations, changes in accounting principles, the effect of implementation or retrospective application of accounting methods, contributions to pension plans, projected benefit payments, projected tax rates, IRS audit outcomes and timing of settlements, and other related matters. Risks, uncertainties and assumptions that may cause actual results to differ materially from these statements, include factors such as the following:

· Performance of the company’s manufacturing operations including unexpected maintenance requirements;

· Successful execution of internal performance plans including restructurings and cost-reduction initiatives;

· Restructuring of our business support functions following the divestiture of the Containerboard, Packaging and Recycling businesses;

· Successful salvage of our storm-damaged timber in the Pacific Northwest;

· Performance of pension fund investments and derivatives;

· The effect of timing of retirements and changes in the market price of company stock on charges for stock-based compensation;

· General economic conditions, including the level of interest rates, strength of the U.S. dollar and housing starts;

· Market demand for our products, which is related to the strength of the various U.S. business segments;

· Energy, chemical and raw material prices;

· Transportation costs;

· Level of competition from domestic and foreign producers;

· Forestry, land use, environmental and other governmental regulation;

· Legal proceedings;

· Changes in accounting principles;

· Weather and loss from fires, floods, windstorms, pest infestation and other natural disasters; and

· Other factors described in our periodic reports under the heading “Risk Factors.”

We are a large exporter, affected by changes in economic activity in Europe and Asia, particularly Japan, and by currency exchange rates, particularly the relative value of the U.S. dollar to the Euro and the Canadian dollar, and restrictions on international trade or tariffs imposed on imports.
