(1) | The number of shares of our common stock issuable upon conversion of the Debentures assumes a selling securityholder would receive the maximum number of shares of common stock issuable in connection with the conversion of the full amount of Debentures held by such selling securityholder at the initial conversion rate of 16.3345 shares of our common stock per $1,000 in principal amount of the Debentures. Because we will pay cash in lieu of fractional shares upon conversion in accordance with the indenture, the total number of shares of common stock that may be sold as presented in this table may exceed the sum of the shares that each of the selling securityholders will hold upon conversion. The conversion rate and the number of shares issuable upon conversion of the Debentures may adjust under circumstances described under Description of Debentures Conversion Rights Conversion Rate Adjustments. Accordingly, the maximum number of shares of our common stock issuable upon conversion of the Debentures may increase or decrease from time to time. | |
(2) | Calculated based on 57,299,788 shares of common stock outstanding on June 30, 2006. In calculating this amount for each holder, we treated as outstanding the number of common shares issuable upon conversion of all of the holders debentures, but we did not assume conversion of any other holders debentures and we included any shares reported by the selling securityholder as being beneficially owned by such holder in addition to the registrable shares. | |
(3) | Selling securityholder is a broker-dealer and therefore an underwriter (based on information provided to us by the selling securityholder). |
