Employee Stock Purchase Plan.  Such additional 100,000 shares are covered by
this Registration Statement.

(3) The Proposed Maximum Offering Price has been calculated in accordance

calculating the Registration Fee.  The computation is based upon the average
of the high and low price of the Common Stock as reported on the Nasdaq
National Market on October 4, 2004 because the price at which the options to
be granted in the future is not currently determinable.
