Pursuant to the Registration Rights Agreement, the Issuer agreed to file, upon request by any of the purchasers of shares in the registered direct offering, a registration statement on Form S-3 (or, if Form S-3 is not then available, on such other appropriate form) with the SEC covering the resale of the shares of Common Stock by Ocho on a continuous basis pursuant to Rule 415 under the Securities Act of 1933, as amended (the "Securities Act"). The Registration Rights Agreement provides that if certain events occur, including the failure to file or obtain effectiveness of the registration statement within the applicable deadlines, or if the registration statement ceases to remain continuously effective for specified periods, the Issuer will be required to pay to Ocho, as partial liquidated damages, an amount in cash equal to 1.0% of the aggregate purchase price paid pursuant to the Purchase Agreement, both on the date of such event and on each monthly anniversary thereof until the event is cured, subject to an aggregate cap of 10.0% of such aggregate purchase price. The Registration Rights Agreement contains customary mutual indemnification and contribution provisions with respect to any losses arising out of or based upon any untrue statement or alleged untrue statement of a material fact, or any omission or alleged omission of a material fact, contained in any registration statement or prospectus, subject to customary limitations. The Registration Rights Agreement terminates upon the date on which there are no Registrable Securities (as defined in the Registration Rights Agreement) outstanding, subject to the survival of the indemnification and miscellaneous provisions.
