WHEREAS, the Holders hold a majority of the currently outstanding Registrable Securities (including all Registrable Securities issuable upon exercise or conversion of any Security) and, as such, pursuant to Section 6(f) of the Registration Rights Agreement, the Holders may waive the right of all Holders to receive the Liquidated Damages;

WHEREAS, the Holders hereby agree to waive the right of all Holders to receive the Liquidated Damages in connection with the Company's failure to respond in writing to the Comment Letter within 20 calendar days of its receipt of the Comment Letter.
