(1)

Assumes conversion of all of the holder’s notes at a conversion rate of 52.1752 shares of common stock per $1,000 principal amount at maturity of the notes. This conversion rate is subject to adjustment, however, as described under “Description of the Notes-Conversion of Notes” in the prospectus. As a result, the number of shares of common stock issuable upon conversion of the notes may increase or decrease in the future.

(2)	Calculated based on Rule 13d-3(d)(i) of the Exchange Act, using 26,798,660 shares of common stock outstanding as of October 31, 2002. In calculating this amount for each holder, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that holder’s notes, but we did not assume conversion of any other holder’s notes.
(3)	Information about other selling securityholders will be set forth in additional prospectus supplements, if required.
(4)	Assumes that any other holders of the notes or any future pledgees, donees, assignees, transferees or successors or from any other such holders of the notes, do not beneficially own any shares of common stock other than the common stock issuable upon conversion of the notes at the initial conversion rate.
(5)	Information about this selling securityholder updates information previously provided as part of our prospectus supplement dated September 11, 2002.

     Investing in the notes or shares of common stock involves risks that are described in the “Risk Factors” section beginning on page 4 of the prospectus.

     Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is November 14, 2002.
