To Prospectus dated July 14, 2000
     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 shareholders. 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, Interlink Management Corporation, a selling shareholder named in the “Selling Shareholders” table in the prospectus, has transferred warrants to purchase 25,000 shares to Timothy Bridgewater (the “Transferee”). In a prospectus supplement dated December 27, 2007, the Transferee was included in the prospectus as a selling shareholder with respect to 15,000 of the transferred shares, and the Transferee has now requested that it be included in the prospectus as a selling shareholder with respect to the remaining 10,000 transferred shares. Accordingly, the “Selling Shareholders” table of the prospectus is supplemented by the information in the table below to these 10,000 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.
