Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or
Standard; Transfer of Listing

     (a) On December 14, 2006 the Company received an Additional Staff
     Determination letter from the Nasdaq Stock Market ("Nasdaq") indicating
     that the Company's securities are subject to delisting from The Nasdaq
     Global Market because the Company has not yet filed its Form 10-Q for the
     fiscal quarter ended October 29, 2006 ("Third Quarter Form 10-Q") and is
     therefore not in compliance with the continued listing standard in Nasdaq
     Marketplace Rule 4310(c)(14).

     The Company previously received similar Staff Determinations from Nasdaq
     regarding failure to timely file its reports for the fiscal quarter ended
     April 30, 2006 ("First Quarter Form 10-Q") and the fiscal quarter ended
     July 30, 2006 ("Second Quarter Form 10-Q") and a Nasdaq Listing
     Qualifications Panel ("Panel") previously set November 10, 2006 as the
     deadline for the Company to file all required restatements, its First
     Quarter Form 10-Q, and its Second Quarter Form 10-Q in order to regain
     compliance with Nasdaq's continued listing standards.

     As previously announced, the Nasdaq Listing and Hearings Review Council
     ("Listing Council"), in response to the Company's request, has called the
     Panel's decision for review and has stayed any future Panel determinations
     to suspend the Company's securities from trading until the review process
     runs its course. If the Listing Council determines it is appropriate, it
     may grant the Company additional time to regain compliance, until the
     earlier of 60 days from the date of its decision or 180 days from the
     Panel's decision.

     The press release issued by the Company on December 18, 2006 in connection
     with this matter is attached hereto as Exhibit 99.1

     The Company continues to cooperate with Nasdaq and will present its views
     with respect to the Additional Staff Determination by December 21, 2006, as
     requested by Nasdaq. It also continues to work diligently to file all
     required reports with the SEC as quickly as possible and thereby regain
     compliance with Nasdaq's listing requirements, but it can provide no
     assurances that it will be able to do so.
