(1)

Assumes conversion of all of the selling securityholder’s notes at the maximum conversion rate of 24.8880 shares of common stock per $1,000 principal amount at maturity of the notes. The conversion rate is subject to adjustment as described under “Description of notes—Conversion rights—Conversion rate adjustments.” As a result, the number of shares of common stock issuable upon conversion of the notes may change in the future. Further, pursuant to the terms of the notes, upon conversion, we will pay cash and deliver shares of our common stock (or, at our election, in lieu of such shares of our common stock, cash or any combination of cash and shares of our common stock), if any, based on a daily conversion value calculated on a proportionate basis for each trading day of a 25 trading-day observation period. Accordingly, the number of shares of our common stock we would actually deliver upon conversion of any notes could be lower than the numbers shown for any holder of notes in this table above.

(2)

Calculated based on Rule 13d-3(d)(1)(i) of the Exchange Act, using 434,673,736 shares of capital stock outstanding as of December 31, 2007. In calculating this amount for each selling securityholder, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that selling securityholder’s notes, but we did not assume conversion of any other holder’s notes.
