Morgan Securities Inc. and Whitebox Advisors, LLC on the other, each of whom we refer to as a “backstop investor”.

We refer to the Debtors’ Second Amended Joint Plan of Reorganization under Chapter 11 of the Bankruptcy Code and the CCAA Plan of Reorganization and Compromise together as the “plans of reorganization”; to the Company’s and its affiliates’ creditor protection proceedings under chapter 11 of the U.S. Bankruptcy Code and the Companies’ Creditors Arrangement Act (Canada), as applicable, as the “creditor protection proceedings”; and to the U.S. Bankruptcy Court for the District of Delaware (In re: AbitibiBowater Inc., et al., Chapter 11, Case No. 09-11296) as the “U.S. Bankruptcy Court”.

The notes offering is being made pursuant to a confidential final offering memorandum dated September 20, 2010.

Forward-Looking Statements

Statements in this report that are not reported financial results or other historical information are “forward-looking statements” within the meaning of the Private

Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of forward-looking terminology such as the words “will,” “could,” “may,” “intend,” “expect,” “estimate,” “believe,” “anticipate,” and other terms with similar meaning indicating possible future events or potential impact on the business or securityholders of the Company.

The reader is cautioned not to place undue reliance on such forward-looking statements, which are not guarantees of future performance. These statements are based on management’s current assumptions, beliefs and expectations, all of which involve a number of business risks and uncertainties that could cause actual results to differ materially. Although we base these forward-looking statements on assumptions that we believe are reasonable when made, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we operate may differ materially from those made in or suggested by the forward-looking statements contained in this report. In addition, even if our results of operations, financial condition and liquidity, and the development of the industry in which we operate are consistent with the forward-looking statements contained in the offering memorandum, those results or developments may not be indicative of results or developments in subsequent periods.

Any forward-looking statements that we make in this report speak only as of the date of such statement, and we do not undertake, and specifically decline, any obligation to update such statements or to publicly announce the results of any revisions to any such statements to reflect future events or developments. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.
