         This prospectus supplement supplements the prospectus dated July 14,
2000, relating to the resale of up to 2,370,741 shares of our common stock, par
value $.01 per share, by certain of our shareholders. The prospectus was filed
as part of our Registration Statement on Form S-3 (No. 333-40760).

         No dealer, salesperson or any other person has been authorized to give
any information or make any representations not contained in this prospectus
supplement or the prospectus and, if given or made, the information or
representations must not be relied upon as having been authorized by us or the
selling stockholders. This prospectus supplement and the prospectus do not
constitute an offer to sell, or a solicitation of an offer to buy, any
securities to any person in any jurisdiction where such an offer or solicitation
would be unlawful. Neither the delivery of this prospectus supplement or the
prospectus nor any sale made hereunder or thereunder shall, under any
circumstance, create any implication that the information contained herein or
therein is correct as of any time subsequent to the date hereof.

         Since the date of the prospectus, Dillon Capital, LLC, a selling
stockholder named in the "Selling Stockholders" table in the prospectus, has
transferred warrants to purchase an aggregate of 20,000 shares of our common
stock to STAT Trading, LLC (the "Transferee"), which was not named as a selling
stockholder in the prospectus. The Transferee has requested that it be included
in the prospectus as selling stockholder of the transferred shares. Accordingly,
the "Selling Stockholders" table of the prospectus is supplemented by the
information in the table below to include the shares that were transferred to
the Transferee, as indicated below. The total number of shares of our common
stock offered by the prospectus, as supplemented by this prospectus supplement,
remains unchanged.
