SELLING SECURITY HOLDERS
The following table sets forth information, as of October 15, 2001, with
respect to the selling holders and the principal amounts of notes beneficially
owned by each selling holder that may be offered under this prospectus. The
information is based on information provided by or on behalf of the selling
holders. The selling holders may offer all, some or none of the notes or common
stock into which the notes are convertible. Because the selling holders may
offer all or some portion of the notes or the common stock, no estimate can be
given as to the amount of the notes or the common stock that will be held by
the selling holders upon termination of any sales. In addition, the selling
holders identified below may have sold, transferred or otherwise disposed of
all or a portion of their notes in transactions exempt from the registration
requirements of the Securities Act. Selling holders, including their
transferees, pledgees or donees or their successors, may from time to time
offer and sell pursuant to this prospectus any or all of the notes and common
stock into which the notes are convertible.
