On January 7, 2009, the Registrant filed its unaudited initial monthly operating report (the “Monthly Operating Report”) with the Bankruptcy Court. A copy of the Monthly Operating Report is contained in the attached Exhibit 99.1 and is incorporated herein by reference.

Limitation on Incorporation by Reference

In accordance with General Instruction B.2 of Form 8-K, the information in this Item 7.01 is being furnished for informational purposes only and shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as otherwise expressly stated in such filing. The filing of this Form 8-K shall not be deemed an admission as to the materiality of any information herein that is required to be disclosed solely by Regulation FD.

Cautionary Statement Regarding Financial and Operating Data

The Registrant cautions investors and potential investors not to place undue reliance upon 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 Registrant. The Monthly Operating Report has been prepared solely for the purpose of complying with the monthly reporting requirements of, and is in a format acceptable to, the Bankruptcy Court. The Monthly Operating Report is limited in scope and only covers a limited time period.

The Monthly Operating Report was not audited or reviewed by independent accountants and was not prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). There can be no assurance that, from the perspective of an investor or a potential investor in the Registrant’s securities, the Monthly Operating Report is complete. The Monthly Operating Report may be subject to future adjustment and reconciliation. The Monthly Operating Report also contains information for periods which are shorter or otherwise different from those required in the Registrant’s reports pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and such information might not be indicative of the Registrant’s financial condition or operating results for the period that would be reflected in the Registrant’s financial statements or in its reports pursuant to the Exchange Act. The information set forth in the Monthly Operating Report should not be viewed as indicative of future results.

The Monthly Operating Report and additional information about the Debtors’ filings under the Bankruptcy Code, including access to court documents and other general information about the Chapter 11 Case, are available online at the Registrant’s claims administration website located at http://www.delclaims.com/caseinfo/C09-14429.html.
