At the Investor’s option, the cap applicable to the exercise of the Warrants may be raised or lowered to any other percentage not in excess of 9.99%, except that any increase will only be effective upon 61-days’ prior notice to us.

Registration rights agreement, description	In conjunction with the issuance of the Convertible Notes and the Warrants, we entered into a Registration Rights Agreement pursuant to which we agreed to file a registration statement covering the sum of (i) 200% of the maximum number of shares underlying the Convertible Notes and (ii) the maximum number of shares underlying the Warrants (the “Registrable Securities”). We have agreed to keep any registration statement we file pursuant to the Registration Rights Agreement effective until the earlier of (i) the date as of which the Investors may sell all of the Registrable Securities covered by the Registration Statement without restriction or limitation pursuant to Rule 144 and without the requirement to be in compliance with Rule 144(c)(1) (or any successor thereto) or (ii) the date on which the Investors shall have sold all of the securities covered by such Registration Statement. We were to use our reasonable best efforts to have the registration statement declared effective within 90 days after the Effective Date (the “Registration Statement Effective Date”). If we failed to register the Registrable Securities or the registration statement is not declared effective by the SEC before the Registration Statement Effective Date, or if on any day after the Registration Statement Effective Date, sales of the Registrable Securities required to be included on the Registration Statement cannot be made (collectively, a “Registration Default”), we will pay to each Investor an amount in cash equal to 1% of the aggregate Purchase Price (as that term is defined in the Securities Purchase Agreement) of the Investor’s Registrable Securities, whether or not the Registrable Securities were included in the registration statement, and 1% per month (or a portion thereof pro rata) that the Registration Default continues to exist. We are not required to make these payment if, when a Registration Default occurs, the Investors can freely sell our common stock pursuant to Rule 144 without restriction or limitation.
