As described in its current report on Form 8-K dated May 9, 2006, the Company’s board of directors has established a special committee comprised of independent directors to conduct an internal review of the Company’s historical stock option practices and related accounting treatment. The special committee will be assisted by independent outside legal counsel and accounting experts. At this time, the special committee has neither completed its review, nor reached any preliminary or final conclusions about the Company’s stock option practices and the related accounting treatment. Until the special committee’s review 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 special committee’s review.
