(1) Assumes conversion of all of the holder’s notes at a conversion rate of 18.2989 shares of common stock per $1,000 principal amount of notes. However, this conversion rate is subject to adjustment as described under “Description of notes — Conversion rights.” As a result, the number of shares of common stock issuable upon conversion of the notes may increase or decrease in the future.

 

(2) Calculated based on Rule 13d-3(d)(1), using 30,054,685 shares of common stock outstanding as of December 3, 2007. In calculating this amount for the holder, the number of shares of common stock issuable upon conversion of all of the holder’s notes are treated as outstanding.

 

(3) The information presented assumes that all of the selling securityholders will fully convert the notes for shares of our common stock and that the selling securityholders will sell all shares of our common stock that they received pursuant to such conversion.

 

(4) The beneficial owner of the securities being offered is a publicly-held entity.

 

(5) Oaktree Capital Management L.P. (“Oaktree”) is the investment manager of the selling securityholder with respect to the offered securities. Oaktree does not own any equity interest in the selling securityholder, but does have voting and dispositive over the offered securities. Lawrence Keele is a principal of Oaktree and is the portfolio manager for the selling securityholder. Mr. Keele, Oaktree and all employees and members of Oaktree disclaim beneficial ownership of the offered securities, except for their pecuniary interest therein. Oaktree has identified itself as an affiliate of a registered broker-dealer and has represented that the notes were acquired in the ordinary course of business and, at the time of the purchase of the notes or the underlying common stock, to Oaktree’s knowledge, the selling securityholder had no agreements or understandings, directly or indirectly, with any person to distribute the notes or underlying common stock.
