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

          The Company received a Nasdaq Staff Determination that the Company was
not in compliance with Marketplace Rule 4310(c)(14) for failing to timely file
the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2007
("Form 10-Q"). The May 17, 2007 Staff Determination is in addition to the Nasdaq
Staff Determination received by the Company on April 18, 2007, regarding the
Company being in violation of Marketplace Rule 4310(c)(14) for not timely filing
its Annual Report on Form 10-K for the year ended December 31, 2006 ("Form
10-K").

         The non-compliance with Marketplace Rule 4310(c)(14) makes the
Company's common stock subject to being delisted from The Nasdaq Stock Market.
In accordance with the procedures of The Nasdaq Stock Market, on April 19, 2007,
the Company requested a hearing with respect to the April 18, 2007 Staff
Determination before the Nasdaq Listing Qualifications Panel ("Panel") to
request an exception to its non-compliance with Marketplace Rule 4310(c)(14). By
operation of Marketplace Rule 4805(a), the Company's hearing request
automatically stayed the delisting of its common stock pending the Panel's
review and determination. The hearing has been scheduled for May 31, 2007. In
accordance with Marketplace Rule 4804(c), the May 17, 2007 Staff Determination
will be heard with the April 18, 2007 Staff Determination during the May 31,
2007 Panel hearing. There can be no assurance that the Panel will grant the
Company's request for an exception that will allow continued listing of the
common stock. Until a determination is made by the Panel, an indicator will be
added to the Company's trading symbol noting the Company's non-compliance.

         A copy of a press release issued by the Company on May 18, 2007
regarding the May 17, 2007 Nasdaq Staff Determination is filed as Exhibit 99.1
to this Current Report on Form 8-K and incorporated herein by reference.
