If the notification relates to a portion of the filing checked above, identify the Item(s) to which the notification relates:

PART I — REGISTRANT INFORMATION

PART II — RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

PART III — NARRATIVE

State below in reasonable detail why Forms 10 - K, 20 - F, 11 - K, 10 - Q, 10 - D, N - SAR, N - CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

As disclosed on the registrant’s Current Report on Form 8-K filed on February 2, 2009, the registrant entered into an Agreement and Plan of Merger with Koosharem Corporation and Select Merger Sub Inc. (the “Merger Agreement”). The registrant is unable to file its Annual Report on Form 10-K for the fiscal year ended November 1, 2008 (the “2008 Form 10-K”) without unreasonable effort or expense because, among other things, the due diligence process and negotiations related to the Merger Agreement diverted significant staff resources and time from the registrant’s normal process of reviewing and completing the 2008 Form 10-K. The registrant is currently in the process of receiving and reviewing certain financial information necessary to finalize the 2008 Form 10-K and the consolidated financial statements included therein. The registrant and its independent accountants are working to complete the 2008 Form 10-K as expeditiously as possible. The registrant expects to file the 2008 Form 10-K on or before the fifteenth calendar day following the prescribed due date.

PART IV — OTHER INFORMATION

The registrant expects to report revenue for fiscal year 2008 of $324.5 million, representing a decrease of approximately $115.3 million, or approximately 26.2%, compared to the revenue for fiscal year 2007. The registrant expects to report an operating loss from continuing operations for fiscal year 2008 of $24.9 million, representing an increase of approximately $19.4 million, or approximately 352.7%, compared to the operating loss from continuing operations in fiscal year 2007. The registrant expects to report a net loss for fiscal year 2008 of approximately $46.3 million, representing an increase of approximately $44.4 million, or approximately 2,293.6%, compared to the net loss for fiscal year 2007. The registrant believes the increase in net loss in fiscal year 2008 compared to fiscal year 2007 is primarily due to the establishment of a valuation allowance of approximately $23.2 million against the registrant’s deferred tax assets in the second quarter of fiscal year 2008, the recording of a pre-tax, non-cash charge of approximately $11.5 million in the third quarter of fiscal year 2008 related to the impairment of intangible assets and goodwill of the U.S. operations and the decline in revenues. The foregoing results are estimates and are subject to change.

Certain statements contained in this Form 12b-25 are forward-looking statements and are identified by words such as “expect,” “believe,” “estimate,” or other similar expressions, including statements regarding the registrant’s expectations regarding the completion of the 2008 Form 10-K, the timing of the filing of the 2008 Form 10-K and the results of operations to be reported. The registrant intends these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to risks, uncertainties and assumptions often beyond the registrant’s control, including the risk that

additional staff resources and time may be needed to complete and file the 2008 Form 10-K and other risks described in the Risk Factors sections in the registrant’s reports and documents filed with the SEC. Actual results may differ materially from anticipated results described in these forward-looking statements. In addition to causing the registrant’s actual results to differ, the factors referred to above may cause the registrant’s intentions to change from those statements of intention set forth in this Form 12b-25. Such changes in the registrant’s intentions may cause the registrant’s results to differ. The registrant’s intentions could change at any time and without notice based upon changes in such factors, the registrant’s assumptions or otherwise. Except as required by applicable law, the registrant does not intend and undertakes no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Given the uncertainties and risk factors that could cause the registrant’s actual results to differ materially from those contained in any forward-looking statement, readers should not place undue reliance upon forward-looking statements and should carefully consider these risks and uncertainties.
