b.       Section 2.1(a)(i) of the Agreement is hereby amended and restated in its entirety as follows:

“The Company agrees that no later than January 31, 2017, it shall prepare and file with the Commission a registration statement on Form S-3 (or another form that is available to the Company if Form S-3 is not available) (the “Resale Shelf Registration Statement”) covering the offer and sale of all Registrable Securities; provided however, that if the Company enters into an underwriting agreement relating to a public offering of its common stock prior to January 31, 2017, then the Company shall have until the expiration of the “lock-up” period provided in such underwriting agreement to file the Resale Shelf Registration Statement, subject to any exceptions provided therein. The Company shall use its reasonable best efforts to cause the Resale Shelf Registration Statement to be declared effective as soon as possible after filing, and to keep the Resale Shelf Registration Statement effective under the Securities Act at all times and take all such other actions as are reasonably necessary to ensure that there is an effective “shelf” registration statement containing a prospectus that remains current covering (and to qualify under required U.S. state securities laws, if any) the offer and sale of all Registrable Securities by the Holders on a continuous basis pursuant to Rule 415 of the Securities Act.”

c.       Section 2.11 of the Agreement is hereby amended to insert the following sentence as the last sentence of the provision: “Notwithstanding the foregoing, the Company shall not be obligated to pay Liquidated Damages in respect of Registrable Securities that are not included in the Resale Shelf Registration Statement or any New Registration Statement as a result of the Staff having informed the Company that such securities may not, as a result of the application of Rule 415, be registered for resale as a secondary offering.”
