(1) Assumes conversion of all of the holder’s notes at an initial conversion rate of approximately 41.84 shares of our common stock for each $1,000 principal amount of notes, or $23.90, subject to adjustment under certain circumstances as described under “Description of the Notes—Conversion.” As a result, the amount of common stock issuable upon conversion of the notes may increase or decrease in the future.
(2) Calculated based on Rule 13d-3(d)(i) of the Exchange Act using 151,188,267 shares of common stock outstanding as of May 1, 2007. In calculating this amount, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that particular holder’s notes. However, we did not assume the conversion of any other holder’s notes.
(3) Includes 20,765 shares of common stock previously held by Brookline Avenue Master Fund, L.P.
