Forward Looking Statements

Information provided and statements contained in this report that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act, Section 21E of the Exchange Act of 1934, and the Private Securities Litigation Reform Act of 1995. Such forward-looking statements only speak as of the date of this report and the company assumes no obligation to update the information included in this report. Such forward-looking statements include information concerning our possible or assumed future results of operations, including descriptions of our business strategy. These statements often include words such as “believe,” “expect,” “anticipate,” “intend,” “plan,” “estimate” or similar expressions. These statements are not guarantees of performance or results and they involve risks, uncertainties and assumptions, including the risk of continued delay in the completion of our financial statements and the consequences thereof, the availability of funds, either through cash on hand or the company’s other liquidity sources, to repay any amounts due should any of the company’s debt become accelerated, and decisions by suppliers and other vendors to restrict or eliminate customary trade and other credit terms for the company’s future orders and other services, which would require the company to pay cash and which could have a material adverse effect on the company’s liquidity position and financial condition. Although we believe that these forward-looking statements are based on reasonable assumptions, there are many factors that could affect our actual financial results or results of operations and could cause actual results to differ materially from those in the forward-looking statements. For a further description of these factors, see Item 1A. Risk Factors of our Form 10-K for the fiscal year ended October 31, 2005, which was filed on December 10, 2007.
