(1) | Because a selling securityholder may sell all or a portion of the notes and common stock issuable upon conversion of the notes pursuant to this prospectus, no estimate can be given as to the number or percentage of notes and common stock that the selling securityholder will hold upon termination of any sales. |
(2) | Represents only shares of common stock issuable upon conversion of the notes. |
(3) | The number of shares of our common stock issuable upon conversion of the notes is calculated assuming conversion of the full amount of notes held by such holder at the initial conversion price of $4.32, which equals a conversion rate of 231.4815 shares per $1,000 principal amount of notes. This conversion rate is subject to adjustment as described under Description of Notes Conversion Price Adjustments contained in the prospectus. Accordingly, the number of shares of common stock to be sold may increase or decrease from time to time. Fractional shares will not be issued upon conversion of the notes. Cash will be paid in lieu of fractional shares. |
Investing in the Convertible Notes and our Common Stock involves risks. See Risk Factors beginning on page 6 of the Prospectus.
