Section 1.4 Agreement to Vote. Hereafter until the Expiration Time, each Company Stockholder hereby unconditionally and irrevocably agrees that, at any meeting of the stockholders of the Company (or any adjournment or postponement thereof), and in any action by written consent of the stockholders of the Company requested by the Company Board or otherwise undertaken in connection with the Transactions (which written consent shall be delivered as promptly as reasonably practicable, and in any event within two (2) Business Days, following the date that the Registration Statement is declared effective by the SEC), such Company Stockholder shall, if a meeting is held, appear at the meeting, in person or by proxy, or otherwise cause its Subject Shares (to the extent such Subject Shares are entitled to vote or provide consent with respect to such matter) to be counted as present thereat for purposes of establishing a quorum, and such Company Stockholder shall vote or provide consent (or cause to be voted or consented), in person or by proxy, all of its Subject Shares (to the extent such Subject Shares are entitled to vote or provide consent with respect to such matter):

(a) to approve and adopt the Business Combination Agreement and the Transactions;

(b) vote or cause to be voted (including by class vote and/or written consent or resolution, if applicable) the Subject Shares in favor of granting the Company Stockholder Approval or, if there are insufficient votes in favor of granting the Company Stockholder Approval, in favor of the adjournment or postponement of such meeting of the stockholders of the Company to a later date;

(c) in any other circumstances upon which a consent, waiver or other approval is required under the Company Organizational Documents or the Company Stockholder Agreements (as defined below) or otherwise sought with respect to the Business Combination Agreement or the Transactions, to vote, consent, waive or approve (or cause to be voted, consented, waived or approved) all of such Company Stockholder’s Subject Shares held at such time in favor thereof;

Each Company Stockholder hereby agrees that it shall not commit or agree to take any action inconsistent with the foregoing; provided, however, that the obligations of the Company Stockholders specified in this Section 1.4 shall not apply, and no Company Stockholder shall be required to vote or act in accordance with clauses (a) through (e) above, from and after such time as the Company Board shall have effected a Change in Recommendation in accordance with the terms of the Business Combination Agreement.

Section 1.5 Proxy. Without limiting any other rights or remedies of Acquiror, in the event that any Company Stockholder fails to perform or otherwise comply with the covenants, agreements or obligations set forth in Section 1.4, such Company Stockholder hereby irrevocably appoints the Company or any individual designated by the Company as such Company Stockholder’s agent, attorney-in-fact and proxy (with full power of substitution and re-substitution), for and in the name, place and stead of such Company Stockholder, to attend on behalf of such Company Stockholder any meeting of the Company Stockholders with respect to the matters described in Section 1.4, to include its Subject Shares in any computation for purposes of establishing a quorum at any such meeting of the Company Stockholders, to vote (or cause to be voted) its Subject Shares or consent (or withhold consent) with respect to any of the matters described herein in connection with any meeting of the Company Stockholders or any action by written consent by the Company Stockholders (including the Written Consent).

The proxyholder may not exercise the proxy granted pursuant to this Section 1.5 on any matter except for those matters set forth in Section 1.4.

Section 1.6 No Challenges. Each Company Stockholder agrees not to commence, join in, facilitate, assist or encourage, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Acquiror, Merger Sub, the Company or any of their respective successors or directors or officers challenging the validity of, or seeking to enjoin or delay the operation of, any provision of this Agreement or the Business Combination Agreement; provided, that nothing in this Section 1.5 shall limit or restrict any Company Stockholder from bringing any claim for actual fraud or willful and material breach of the Business Combination Agreement.

Section 1.7 No Other Consideration. Each Company Stockholder agrees to accept the delivery of the Per Share Merger Consideration to such Company Stockholder at the Closing in accordance with the terms of the Business Combination Agreement, and agrees that once such Per Share Merger Consideration is delivered to such Company Stockholder, no other consideration may be claimed by such Company Stockholder in respect of such Company Stockholder’s equity in the Company immediately prior to Closing except as otherwise expressly provided in the Business Combination Agreement and any Ancillary Agreement.

Each Company Stockholder will promptly provide any information reasonably requested by Acquiror or the Company for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the SEC).

Section 1.13 Termination of Company Stockholder Agreements, Related Agreements.

The definitions contained in this Agreement are applicable to the masculine as well as to the feminine and neuter genders of such term. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. “Writing,” “written” and comparable terms refer to printing, typing and other means of reproducing words (including electronic media) in a visible form.

Section 3.12 No Ownership Interest.
