1. Definitions. All initial capitalized terms used but not otherwise defined herein shall have the meanings set forth in the Purchase Agreement.

2. Shares Subject to Agreement. The term “Voting Shares” as used in this Voting Agreement shall refer, individually and collectively, to (i) the Shares, and (ii) any other shares of the Company’s capital stock owned (whether beneficially or as of record) by the Stockholders on or after the date hereof (the “Additional Shares”). The Stockholders hereby agree to hold any Voting Shares controlled or owned by them (whether beneficially or as of record), subject to the provisions of this Voting Agreement.

3. Manner of Vote. Any vote of the Voting Shares held by the Stockholders, whether at any meeting of the stockholders of the Company (including any adjournment(s), postponement(s) or continuation(s) thereof) or by written consent in lieu of a meeting of the stockholders of the Company, shall be exercised exclusively by such person (the “Proxy”) designated from time to time by the Company’s Board of Directors (the “Board”) by written notice to the Stockholders; provided, that, if the voting power held by the Proxy, when taking into account the proxies granted by the Stockholders by this Section 3 and Section 4 of this Agreement and the Company Common Stock beneficially owned by the Proxy, represents 20% or more of the voting power of the Company’s stockholders that will vote on an item, then the Proxy shall vote such number of Voting Shares in excess of 19.9% of the voting power of the existing stockholders of the Company on such item in the same proportion as shares of Company Common Stock are voted by the Company’s other stockholders. The initial Proxy shall be Oren Elmaliah. Any vote of the Voting Shares by any person other than the then Proxy shall be invalid, and shall not count as a vote of Voting Shares for any purpose whatsoever.

4. Irrevocable Proxy Coupled with an Interest.

(b) The irrevocable proxy and power of attorney granted by each Stockholder pursuant to this Section 4 is: (i) intended to be and shall be irrevocable to the full extent permitted by the Delaware General Corporation Law, (ii) coupled with an interest sufficient in law to support an irrevocable power, and (iii) granted in consideration of the Company issuing the Shares to the Stockholders, entering into this Voting Agreement and incurring certain related fees and expenses.

5. Representations and Warranties of the Stockholders. Each of the Stockholders represents, warrants and covenants to the Company as follows:

(a) Upon the issuance of the Shares to the Stockholder under the Purchase Agreement, the Stockholder shall be the sole legal and beneficial owner of such Shares which securities represent the only securities of the Company legally or beneficially owned by the Stockholder or that the Stockholder has voting power over. Except with respect to the Purchase Agreement, the Stockholder is not a party to any contract or agreement and owns no warrants, options or rights to purchase, subscribe for or otherwise acquire any securities of the Company. No person not a signatory to this Voting Agreement has a beneficial interest in or a right to acquire or vote any of the Voting Shares. Upon issuance, the Shares and any Additional Shares will be, free and clear of any lien, charge, claim, security interest, proxy, power of attorney, encumbrance, voting trust or agreement, understanding or arrangement of whatever nature that would adversely affect, or be inconsistent or interfere with, the Stockholder’s ability to vote the Voting Shares in accordance with Section 3 above or the Stockholder’s ability to grant and the Proxy’s ability to exercise the irrevocable proxy and power of attorney pursuant to Section 4 above.
