(1) Assumes conversion of all of the selling securityholders' notes at the maximum conversion rate of 76.2311 shares per note. However, the maximum conversion rate is subject to adjustment as described under "Description of the Notes-Conversion Rate Adjustments." As a result, the amount of common stock issuable upon conversion of the notes may increase or decrease in the future. (2) We do not know when or in what amounts a selling securityholder may offer notes or shares of our common stock issuable upon conversion of the notes for sale. The selling securityholders might not sell any or all of the notes or shares of our common stock issuable upon conversion of the notes offered by this prospectus. Because the selling securityholders may offer all or some of the notes or shares of our common stock issuable upon conversion of the notes pursuant to this offering, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the notes or shares of our common stock issuable upon conversion of the notes, we cannot estimate the number of the notes or shares of our common stock issuable upon conversion of the notes that will be held by the selling securityholders after the completion of the offering. However, for purposes of this table, we have assumed that, after completion of the offering, none of the notes or shares of our common stock issuable upon conversion of the notes covered by this prospectus will be held by the selling securityholders. (3) Assumes that any other holders of notes, or any future transferees, pledgees, donees or successors of or from any such other holders of notes, do not beneficially own any shares of our common stock other than the shares of our common stock issuable upon conversion of the notes. Information about other selling securityholders will be set forth in an amendment to the registration statement of which this prospectus is a part or in prospectus amendments or supplements, as required. None of the selling securityholders has held any position or office with, or has otherwise had a material relationship with, us or any of our subsidiaries within the past three years. S-3
