The following table contains information as of November 2, 2001, with
respect to certain selling securityholders and the principal amount of notes and
underlying common stock beneficially owned by each of the selling
securityholders listed herein that may be offered using this prospectus. The
information is based on information provided by or on behalf of the selling
securityholders and may have changed as of the date hereof. Because the selling
securityholders may offer all or some of their notes or the underlying common
stock from time to time, we cannot estimate the amount of the notes or
underlying common stock that will be held by the selling securityholders upon
the termination of any particular offering. The column showing ownership after
completion of the offering assumes that the selling securityholders will sell
all of the securities offered by this prospectus. The selling securityholders
listed in the table may have sold or transferred, in transactions exempt from
the registration requirements of the Securities Act, some or all of their notes
since the date on which the information in table is presented. Information about
the selling stockholders may change over time. Any change in this information
will be set forth in prospectus supplements, if required. None of the selling
securityholders or any of its affiliates, officers, directors or principal
equity holders has held any position or office or has had any material
relationship with us or our affiliates within the past three years.
