As described in its current report on Form 8-K dated June 15, 2006, the Company’s board of directors has appointed one of its outside directors to oversee an investigation of the Company’s historical stock option practices and related accounting treatment.  The outside director is being assisted by outside legal counsel that had not previously been involved with the Company’s stock option plans and forensic accountants.  At this time, the outside director has not completed the work or reached final conclusions and is continuing the investigation.  Until the investigation is complete, the Company will be unable to prepare and file its Form 10-Q.  The Company intends to file its Form 10-Q as soon as practicable after the completion of the investigation.
