(1)             Assumes conversion of the notes into shares of common stock at a conversion rate of 20.4298 shares of common stock per each $1,000 principal amount of notes.

(2)             Based on a total of 136,920,414 shares of our common stock outstanding as of May 1, 2007.

(3)             We do not know when or in what amounts a selling shareholder may offer shares of our common stock for sale. The selling shareholders might not sell any or all of the shares of our common stock offered by this prospectus. Because the selling shareholders may offer all or some of the shares of our common stock pursuant to this prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares of our common stock, we cannot estimate the number of shares of our common stock that will be held by the selling shareholders after completion of this offering. However, for purposes of this table, we have assumed that, after completion of the offering pursuant to this prospectus, none of the shares of our common stock covered by this prospectus will be held by the selling shareholders

(4)             Additional selling shareholders not named in the prospectus will not be able to use the prospectus for resales until they are named in the selling shareholder table by prospectus supplement or post-effective amendment. Transferees, successors and donees of identified selling shareholders will not be able to use this prospectus for resales until they are named in the selling shareholders table by prospectus supplement or post-effective amendment. If required, we will add transferees, successors and donees by additional prospectus supplement in instances where the transferee, successor or donee has acquired its shares from holders named in the prospectus or prospectus supplement after the effective date of this prospectus.

(5)             We will issue cash for all fractional shares of our common stock based on the closing sale price of our common stock on the trading day immediately preceding the exchange date.
