This news release contains forward-looking statements, as defined in applicable legislation, including statements that express management’s expectations or estimates of future performance. Often, but not always, words such as “intention,” “proposed,” “expected,” “will,” “intends,” and “will not” and other expressions which are predictions of or indicate future events, trends or prospects and which do not relate to historical matters identify forward-looking statements. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Norbord to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

Although Norbord believes it has a reasonable basis for making these forward-looking statements, readers are cautioned not to place undue reliance on such forward-looking information. By its nature, forward-looking involves numerous assumptions, inherent risks and uncertainties, both general and specific, which contribute to the possibility that the predictions, forecasts and other forward-looking statements will not occur. Factors that could cause actual results to differ materially from those contemplated or implied by forward-looking statements include: general economic conditions; risks inherent with product concentration; effects of competition and product pricing pressures; risks inherent with customer dependence; effects of variations in the price and availability of manufacturing inputs; risks inherent with a capital intensive industry; and other risks and factors described from time to time in filings with Canadian securities regulatory authorities.

Except as required by applicable laws, Norbord does not undertake to update any forward-looking statements, whether as a result of new information, future events or otherwise, or to publicly update or revise the above list of factors affecting this information.
