Forward Looking Statements
Information provided and statements contained in this news release 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, and the Private Securities Litigation Reform Act of 1995. Such forward-looking statements only speak as of the date of the news release and the company assumes no obligation to update the information included in the news release. 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 Exhibit 99.1 to our Form 8-K filed on April 12, 2006. In addition, the financial information presented in this release is preliminary and unaudited and is subject to change based on the completion of our on-going review of accounting matters, the completion of our fiscal year 2005 and 2006 annual financial statements and the completion of the restatement of our financial results for the fiscal years 2002 through 2004 and for the first nine months of fiscal 2005. It is likely that the process of restating the prior year financial statements will require changes to the company's financial statements for 2005 and 2006 due to revised application of certain accounting principles and methodologies that, individually or in the aggregate, may be material.
