(1) Assumes conversion of all of the holder’s notes at an initial conversion rate of 69.8348 shares per $1,000 principal amount of notes. However, this conversion rate is subject to adjustment as described under the section entitled “Description of Notes — Conversion Rights” in the prospectus to which this supplement refers. As a result, the amount of common stock issuable upon conversion of the notes may increase or decrease in the future.
(2) Assumes that the selling security holder holds no shares of our common stock shown as being issuable upon the assumed conversion of the notes listed next to his name after the offering.
(3) Calculated based on Rule 13d-3(d)(1)(i) of the Exchange Act using 58,843,303 shares of common stock outstanding as of April 21, 2005. In calculating this amount, we treated as outstanding the number of shares of common stock issuable upon conversion of all of that particular selling security holder’s notes. However, we did not assume the conversion of any other holder’s notes. We have assumed that the selling security holder holds no notes following the offering.
(4) Includes $500,000 principal amount of notes previously included in the prospectus. The selling security holder has identified itself as an affiliate of a registered broker-dealer and has represented to us that it purchased the notes for investment purposes and not with a view toward distribution of such notes. Patrick Corrigan has voting or investment power over these securities.
(5) SuttonBrook Capital Management LP is the investment manager of SuttonBrook Capital Portfolio LP and John London and Steve Weinstein are the natural persons with control over SuttonBrook Capital Management LP which has dispositive power over the securities.
