(1) Assumes conversion of all of the holder’s debentures at a conversion rate of 32.0760 shares of common stock per $1,000 principal amount at maturity of the debentures. This conversion rate is subject to adjustment as described under ‘‘Description of Debentures—Conversion Rights.’’ As a result, the number of shares of common stock issuable upon conversion of the debentures may increase or decrease in the future. Further, pursuant to the terms of the debentures, upon conversion, we will deliver cash equal to the lesser of the aggregate principal amount of debentures to be converted and the total conversion obligation. We will deliver shares of our common stock, cash or a combination thereof, at our option for the remainder, if any, of our conversion obligation. Accordingly, the number of shares of our common stock we would actually deliver upon conversion of any debentures would be lower than the number shown for any holder of debentures in this table above. Excludes shares of common stock that may be issued by us upon the repurchase of the debentures as described under ‘‘Description of Debentures— Repurchase of the Debentures by Us at the Option of Holders Upon a Fundamental Change’’ and fractional shares. Holders will receive a cash adjustment for any fractional share amount resulting from conversion of the debentures, as described under ‘‘Description of Debentures—Conversion Rights.’’
 
(2) The number of shares of common stock beneficially owned by each holder named above is less than 1% of our outstanding common stock, calculated based on 298,017,510 shares of common stock outstanding as of June 11, 2007. In calculating this amount for each holder, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that holder’s debentures, but we did not assume conversion of any other holder’s debentures.
 
(3) For the purposes of computing the number and percentage of debentures and shares to be held by the selling securityholders after the conclusion of the offering, we have assumed for purposes of the table above that the selling securityholder named above will sell all of the debentures and all of the common stock issuable upon conversion of the debentures offered by this prospectus supplement and the prospectus, and that any other shares of our common stock beneficially owned by the selling securityholder will continue to be beneficially owned. We also assume that unnamed holders of debentures, or any future transferees, pledgees, donees or successors of from any such holder, do not beneficially own any common stock other than that issuable upon conversion of the debentures.
 
(4) The maximum principal amount of debentures that may be sold under this prospectus and prospectus supplement will not exceed $1,000,000,000.
