SELLING SECURITY HOLDERS

The information set forth in the tables of selling security holders was furnished to us on or before May 11, 2007.

In addition, the selling security holders listed in the tables may have acquired, sold or transferred, in transactions exempt from the registration requirements of the Securities Act of 1933, some or all of their notes, or common stock issuable upon conversion of the notes, since the date as of which the information in the table is presented.

(1) Because the selling security holder may sell pursuant to the prospectus all or a portion of the offered notes or common stock issuable upon conversion of the notes, we cannot know or estimate the number or percentage of notes and common stock that the selling security holder will hold upon the termination of any particular offering. Please refer to the “Plan of Distribution” beginning on page 71 of the prospectus. The information presented assumes that the selling security holder will fully convert the notes for cash and shares of our common stock, and that the selling security holder will sell all shares of our common stock that it receives pursuant to such conversion.

The maximum aggregate principal amount of Notes that may be sold pursuant to this prospectus will not exceed $250,000,000.

 

(2) Includes shares of our common stock issuable upon conversion of the notes.

 

(3) The maximum number of shares of our common stock issuable upon conversion of the notes is calculated assuming the conversion of the full amount of notes held by the selling security holders at the initial conversion price of $48.48 per share, which corresponds to the initial conversion rate of 20.6260 shares per $1,000 principal amount of the notes. This conversion price is subject to adjustment as described under “Description of Notes—Conversion Rights—Conversion Rate Adjustments.” Accordingly, the number of shares of our common stock to be offered using this prospectus may increase or decrease over time. Fractional shares will not be issued upon conversion of the notes. Instead, we will pay cash in lieu of fractional shares, if any. Due to the effects of rounding, the numbers shown in this column do not equal exactly 20.6260 shares per $1,000 principal amount of the notes.
