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 indicating that the Company's securities are
      subject to delisting from The Nasdaq National 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 has requested
      a hearing before a Nasdaq Listing Qualifications Panel to review the Staff
      Determination.


      The press release issued by the Company on June 20, 2006 in connection
      with this matter is attached hereto as Exhibit 99.1
