Cautionary Statement Regarding Financial Operating Data

The Company cautions investors and potential investors not to place undue reliance on the information contained in the Monthly Operating Report, which was not prepared for the purpose of providing the basis for an investment decision relating to any of the securities of the Company. The Monthly Operating Report is limited in scope, covers a limited time period and has been prepared solely for the purpose of complying with the monthly reporting requirements of the Bankruptcy Court. The Monthly Operating Report was not prepared in accordance with Generally Accepted Accounting Principles in the United States, has not been audited or reviewed by independent accountants, is in a format prescribed by applicable bankruptcy laws and is subject to future adjustment and reconciliation. There can be no assurance that, from the perspective of an investor or potential investor in the Company’s securities, the Monthly Operating Report is complete. The Monthly Operating Report also contains information for periods which are shorter than or otherwise different from those required in the Company’s reports pursuant to the Securities Exchange Act of 1934 (the “Securities Exchange Act”), and such information may not be indicative of the Company’s financial condition or operating results for the period that would be reflected in the Company’s financial statements or in its reports pursuant to the Securities Exchange Act.
