Item 8.01 Other Events

On August 17, 2006 the Company received a letter from John D. "Jack" Poe
advising that he was stepping down from his position as Chairman of the Board of
Directors of the Company ("Board") effective immediately. He further informed
the Company that he was taking a leave of absence as a member of the Board, also
effective on August 17, 2006, pending the conclusion of the current
investigation of stock options granting practices. Mr. Poe informed the Company
that he was taking these actions in order to avoid even the appearance of a
conflict of interest.

On August 25, 2006 the Company announced that the Board appointed Rockell N.
Hankin as its Chairman on August 24, 2006.
