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

     (a) On June 15, 2006 the Company received a Staff Determination letter from
     the Nasdaq Stock Market ("Nasdaq") indicating that the Company's securities
     are subject to delisting from The Nasdaq National Market (now the Nasdaq
     Global Market) because the Company has not yet filed its Form 10-Q for the
     fiscal quarter ended April 30, 2006 and is therefore not in compliance with
     the continued listing standard in Nasdaq Marketplace Rule 4310(c)(14). The
     Company requested a hearing before a Nasdaq Listing Qualifications Panel
     ("Panel") to review the Staff Determination and on August 29, 2006 the
     Panel granted the Company's request for additional time to regain
     compliance, setting November 10, 2006 as the date by which the Company must
     file the First Quarter Form 10-Q and all required restatements. For
     information on the Company's pending restatement of its historical
     financial statements, related to stock-based compensation, see the Form 8-K
     filed by the Company on July 20, 2006.

     On September 13, 2006 the Company received an Additional Staff
     Determination from Nasdaq (the "September Notice") indicating that the
     Company's failure to timely file its Form 10-Q for the fiscal quarter ended
     July 30, 2006 ("Second Quarter Form 10-Q") is an another instance of
     noncompliance with the continued listing standard in Nasdaq Marketplace
     Rule 4310(c)(14) and an additional basis for delisting. The September
     Notice states that the Panel will consider the additional deficiency in
     rendering a determination regarding the Company's continued listing and
     invites the Company to present its views with respect to this matter no
     later than September 20, 2006. The Company continues to cooperate with
     Nasdaq and will timely submit its comments to the Panel.

     The delayed filing of the Second Quarter Form 10-Q had been previously
     contemplated by the Company and was therefore incorporated into the plan of
     compliance presented by the Company to the Panel at the hearing in August
     2006. The Company expects to file the Second Quarter Form 10-Q by the
     November 10, 2006 deadline established by Nasdaq with respect to its
     restated historical financial statements and the First Quarter Form 10-Q.

     The press release issued by the Company on September 15, 2006 in connection
     with this matter is attached hereto as Exhibit 99.1

     Although the Company expects to file all required reports with the SEC by
     November 10, 2006, and thereby regain compliance with Nasdaq's continued
     listing requirements, it can provide no assurances that it will be able to
     do so.
