         This prospectus supplement supplements the prospectus dated May 25,
2001, relating to the resale of up to 1,950,242 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. 333-60856).

         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, Avalanche Resources, Ltd., a selling
shareholder named in the "Selling Shareholders" table in the prospectus, has
transferred warrants to purchase an aggregate of 58,823 shares of our common
stock to Kevin Maddox (the "Transferee"). The Transferee is an individual who is
already separately named in the prospectus as a selling shareholder of 25,000
shares. The Transferee has requested that he be included in the prospectus as
selling shareholder of the transferred shares. Accordingly, the "Selling
Shareholders" 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.
