Capitalized terms used herein and not otherwise defined herein shall have the meanings ascribed to them in the Investment Agreements.

As of the date hereof, the undersigned (“Stockholder”) is the record or beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended, which meaning will apply for all purposes of this Acknowledgment and Support Agreement (this “Support Agreement”) whenever the term “beneficial owner” or “beneficially own” is used) of the number of shares of common stock, par value $0.0001 per share of the Company (the “Company Common Stock”), set forth below Stockholder’s name on the signature page hereto (all such shares of Company Common Stock, including securities convertible into or exercisable or exchangeable for Company Common Stock, for which Stockholder is or becomes the record or beneficial owner in a personal capacity (and for the avoidance of doubt excluding any shares held by affiliated funds) prior to the termination of this Support Agreement being referred to herein as the “Covered Shares” ).

Stockholder acknowledges and agrees that the execution of this Support Agreement and its delivery to Purchaser by Stockholder is a material inducement to Purchaser to enter into the Investment Agreements and purchase the Shares. Stockholder hereby acknowledges and agrees to the following:

1. Stockholder Vote.

(a) At any meeting of the stockholders of the Company, however called, or at any adjournment thereof, or in any other circumstance in which the vote, consent or

(iii) in favor of any adjournment or postponement recommended by the Company in order to obtain the Stockholder Approval if there are not sufficient votes in favor of the Stockholder Approval, and

UNTIL THE TERMINATION TIME, STOCKHOLDER WILL TAKE SUCH FURTHER ACTION AND WILL EXECUTE SUCH OTHER INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY. STOCKHOLDER HEREBY REVOKES ANY AND ALL PREVIOUS PROXIES

OR POWERS OF ATTORNEY GRANTED WITH RESPECT TO ANY OF THE COVERED SHARES THAT MAY HAVE HERETOFORE BEEN APPOINTED OR GRANTED WITH RESPECT TO THE MATTERS REFERRED TO IN THIS SECTION 2(A), AND PRIOR TO THE TERMINATION TIME NO SUBSEQUENT PROXY (WHETHER REVOCABLE OR IRREVOCABLE) OR POWER OF ATTORNEY SHALL BE GIVEN BY STOCKHOLDER. NOTWITHSTANDING THE FOREGOING, THIS PROXY SHALL TERMINATE UPON TERMINATION OF THIS SUPPORT AGREEMENT IN ACCORDANCE WITH ITS TERMS.

3. No Inconsistent Arrangements.

5. Miscellaneous.

(a) This Support Agreement shall be governed by, and construed in accordance with, the Laws of the state of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the state of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the state of Delaware. Any dispute relating hereto shall be heard first in the Delaware Court of Chancery, and, if applicable, in any state or federal court located in of Delaware in which appeals from the Court of Chancery may validly be taken under the laws of the State of Delaware (each a “Chosen Court” and collectively, the “Chosen Courts”), and the parties agree to the exclusive jurisdiction and venue of the Chosen Courts. Such persons further agree that any proceeding seeking to enforce any provision of, or based on any matter arising out of or in connection with, this Support Agreement or the transactions contemplated hereby or by any matters related to the foregoing (the “Applicable Matters”) shall be brought exclusively in a Chosen Court, and that any proceeding arising out of this Support Agreement or any other Applicable Matter shall be deemed to have arisen from a transaction of business in the state of Delaware, and each of the foregoing persons hereby irrevocably consents to the jurisdiction of such Chosen Courts in any such proceeding and irrevocably and unconditionally waives, to the fullest extent permitted by law, any objection that such person may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such Chosen Court or that any such proceeding brought in any such Chosen Court has been brought in an inconvenient forum. Such persons further covenant not to bring a proceeding with respect to the Applicable Matters (or that could affect any Applicable Matter) other than in such Chosen Court and not to challenge or enforce in another jurisdiction a judgment of such Chosen Court. Process in any such proceeding may be served on any person with respect to such Applicable Matters anywhere in the world, whether within or without the jurisdiction of any such Chosen Court.

(d) This Support Agreement, and any amendments hereto, to the extent signed and delivered by means of an electronic transmission, including by a facsimile machine or via email, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. Neither party hereto or to any such agreement or instrument shall raise the use of electronic transmission by a facsimile machine or via email to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through such electronic transmission as a defense to the formation of a contract and each such party forever waives any such defense. This Support Agreement may be executed in separate counterparts, each of which will be an original and all of which together shall constitute one and the same agreement binding on each party hereto.

(e) Neither party hereto shall be deemed to have waived any claim arising out of this Support Agreement, or any power, right, privilege or remedy under this Support Agreement, unless the waiver of such claim, power, right, privilege or remedy is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.
