Assumes conversion of all of the holder’s notes at a conversion rate of 69.6621 shares per $1,000 principal amount of notes, conversion of all of the 0.5% Convertible Subordinated Notes due 2008 held by such holder at a conversion rate of 49.1884 shares per $1,000 principal amount of the 0.5% Convertible Subordinated Notes and conversion of all of the 1.0% Convertible Subordinated Notes due 2010 held by such holder at a conversion rate of 77.8743 shares per $1,000 principal amount of the 1.0% Convertible Subordinated Notes. The conversion rate of the notes, the 0.5% Convertible Subordinated Notes and the 1.0% Convertible Subordinated Notes are subject to adjustment.

Calculated based on Rule 13d-3(d)(1)(i) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) using 53,371,044 million shares of common stock outstanding as of February 1, 2008. In calculating this amount, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that particular holder’s notes, 0.5% Convertible Subordinated Notes due 2008 and 1.0% Convertible Subordinated Notes due 2010. However, we did not assume the conversion of any other holder’s notes, 0.5% Convertible Subordinated Notes or 1.0% Convertible Subordinated Notes. |

The selling securityholder has indicated that Credit Suisse Securities (USA) LLC is a registered broker-dealer pursuant to Section 15 of the Exchange Act. The selling securityholder has represented that it has acquired its securities in the ordinary course of business and, at the time of the acquisition of the securities, it has no agreements or understandings, directly or indirectly with any person to distribute the securities. |
We prepared this prospectus supplement based on the information supplied to us by the selling securityholder named in the table. The information provided in this prospectus supplement is current as of February 13, 2008.
The selling securityholders listed above and in the prospectus may have sold or transferred some or all of their notes or the underlying common stock since the date on which they provided us with information regarding their notes and common stock, and we have not made any independent inquires as to the foregoing. Information about selling securityholders may change over time. Any changed information will be set forth to the extent provided to us by the selling securityholders, in further supplements to the prospectus, if and when necessary.
Because the selling securityholders listed above and in the prospectus 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. See “Plan of Distribution” in the prospectus and below.
PLAN OF DISTRIBUTION
Any selling securityholder that is a broker-dealer may be deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act of 1933, as amended (the “Securities Act”) with respect to the securities it sells pursuant to the prospectus. As a result, the SEC may deem any profits the selling securityholders make by selling the securities and any discounts, commissions or concessions received by any broker-dealers or agents who participate in the distribution of the securities to be underwriting discounts and commissions under the Securities Act. Selling securityholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act and may also be subject to liabilities under the securities laws, including Sections 11, 12 and 17 of the Securities Act and Rule 10b-5 under the Exchange Act. To our knowledge, there are currently no plans, arrangements or understandings between any selling securityholders and any underwriter, broker-dealer or agent regarding the sale of the securities. The following additional selling securityholder has identified itself as a registered broker-dealer: Credit Suisse Securities (USA) LLC. For details about the amount of notes and number of shares beneficially owned and being offered by this selling securityholder, see “Selling Securityholders” above.
