| (6) | Information concerning other selling securityholders will be set forth in prospectus supplements or in an amendment to the registration statement of which this prospectus is a part if and when necessary. Totals in these columns may exceed the number of Warrants and common stock offered by this prospectus as a result of the selling securityholders identified above having sold, transferred or otherwise disposed of some or all of their Warrants since the date on which the information in the preceding table was provided to us without informing us of such sale(s). In no event will the number of Warrants offered by this prospectus or any related prospectus supplement exceed 10,000,000. Similarly, the total number of shares of our common stock issuable upon the exercise of all the Warrants may increase or decrease due to adjustments to the exercise price resulting from certain transactions by the company such as payment of dividends on its common stock. Pursuant to Rule 416 under the Securities Act, the registration statement of which this prospectus is a part also covers any additional shares of our common stock which become issuable in connection with the Warrants because of any dividend, stock split, recapitalization or other similar event or adjustment in the number of shares issuable upon exercise of the Warrants. |
