⁽¹⁾ Assumes no conversion of the notes, which conversion may occur upon the satisfaction of several conditions described in the section of the prospectus entitled “Description of the Notes—Conversion of Notes.”

⁽²⁾ Represents the maximum number of shares of common stock issuable upon conversion of the notes based upon a conversion factor of .053526 multiplied by the principal amount of the notes beneficially held. These conversion factors are subject to adjustments as described in the section of the prospectus entitled “Description of the Notes—Conversion of Notes—Conversion Price Adjustments.” As a result, the maximum number of shares of common stock issuable upon conversion of the notes will correspondingly decrease or increase to the extent that the conversion factors for the notes increase or decrease.

⁽³⁾ Assumes that either all of the principal amount of notes offered hereby or all of the shares of common stock issued are sold by the selling securityholders.

⁽⁴⁾ Assumes that the securityholders convert the principal amount of our notes held by such holder into shares of common stock at a conversion price of $18.6825 per share.

⁽⁵⁾ This number represents the difference between the aggregate principal amount of the notes sold ($200 million in total) and the aggregate principal amount of notes held by the selling securityholders who we have identified as of the date of this prospectus supplement, based upon information provided to us by such selling securityholders. We intend to file a supplement to this prospectus to identify additional selling securityholders, who we have not identified as of the date of this prospectus, prior to the sale of securities held by such selling securityholders.

The fifth sentence of the ninth paragraph of the section of the prospectus entitled “Plan of Distribution” is hereby amended and restated in its entirely to read as follows:

Credit Suisse First Boston LLC, CSS, LLC, Goldman Sachs & Co., KBC Financial Products USA Inc., Lehman Brothers Inc. and SG Americas Securities, LLC have informed us that they are broker-dealers, and, as a result, they are underwriters in connection with the sale of the notes and the underlying shares of common stock.
