(1)   Because a selling security holder may sell all or a portion of the notes and common stock issuable upon conversion of the notes pursuant to this prospectus, an estimate can not be given as to the number or percentage of notes and common stock that the selling security holder will hold upon termination of any sales. The information presented assumes that all of the selling security holders will fully convert the notes for cash and shares of our common stock and that the selling security holders will sell all shares of our common stock that they received pursuant to such conversion.
 
(2)   Includes shares of common stock issuable upon conversion of the notes.
 
(3)   The number of shares of our common stock issuable upon conversion of the notes is calculated assuming (i) that the notes are worth $600,000,000 at the time of conversion, with the $300,000,000 principal amount paid in cash and the remaining $300,000,000 paid in shares of our common stock and (ii) the conversion of the full amount of notes held by such holder at the conversion rate of 31.1200 shares per $1,000 principal amount of the notes, which is equivalent to a conversion price of approximately $32.14. This conversion rate is subject to adjustment as described under “Description of Notes — Conversion Price Adjustments”. Accordingly, the number of shares of our common stock to be sold may increase or decrease from time to time. As a result of the Company’s two for one stock split paid on December 8, 2005, effective as of December 2, 2005, the initial conversion rate of the notes of 15.5600, which was equivalent to a conversion price of approximately $64.27 per share of common stock, was changed to 31.1200 shares of common stock per $1,000 principal amount of the notes, which is equivalent to a conversion price of approximately $32.14 per share of common stock. Fractional shares will not be issued upon conversion of the notes. Cash will be paid instead of fractional shares, if any.
 
(4)   This selling security holder has identified itself as an affiliate of a registered broker-dealer and has represented to us that such selling security holder acquired its notes or underlying common stock in the ordinary course of business and, at the time of the purchase of the notes or the underlying common stock, such selling security holder had no agreements or understandings, directly or indirectly, with any person to distribute the notes or underlying common stock. To the extent that we become aware that such selling security holder did not acquire its notes or underlying common stock in the ordinary course of business or did have such an agreement or understanding, we will file a post- effective amendment to the registration statement of which this prospectus forms a part to designate such affiliate as an “underwriter” within the meaning of the Securities Act of 1933.
 
(5)   This selling security holder has identified itself as a registered broker-dealer and, accordingly, it is deemed to be, under the interpretations of the Securities and Exchange Commission, an “underwriter” within the meaning of the Securities Act of 1933. Please see “Plan of Distribution” for required disclosure regarding these selling security holders.
 
(6)   Due to the effects of rounding, does not equal exactly 31.1200 shares per $1,000 principal amount of the notes.

     Selling security holders who are registered broker-dealers are deemed to be “underwriters” within the meaning of the Securities Act of 1933. In addition, selling security holders who are affiliates of registered broker-dealers may be deemed to be “underwriters” within the meaning of the Securities Act of 1933 if such selling security holder (i) did not acquire its notes or underlying common stock in the ordinary course of business or (ii) had any agreement or understanding, directly or indirectly, with any person to distribute the notes or underlying common stock. To our knowledge, no selling security holder who is a registered broker-dealer or an affiliate of a registered broker-dealer received any securities as underwriting compensation.
