The Stockholder hereby agrees to tender, pursuant to and in accordance with the terms of the Offer, his Owned Shares, and agrees that, prior to the Outside Time, he will not withdraw or permit the withdrawal of the tender of his Owned Shares in response to the Offer as the Offer may be amended from time to time pursuant to and in accordance with the terms of the Merger Agreement.

Provided that the conditions to the Offer are satisfied or waived by Parent and/or Merger Sub, Parent shall cause Merger Sub to purchase the Owned Shares in accordance with the terms of the Offer.

1.2 Voting. Stockholder agrees that, during the period from the date of this Stockholder Tender Agreement through the Outside Time, at any meeting of stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, Stockholder shall, unless otherwise directed in writing by Parent, vote the Subject Securities or cause the Subject Securities to be voted (to the extent such securities are entitled to be voted and are not voted by Parent as proxy in accordance with the Proxy granted herein) in such Stockholder’s sole capacity as a stockholder:

(a) against any action or agreement that would result in a breach of any representation, warranty, covenant or obligation of the Company in the Merger Agreement;

(b) against any action or agreement that would cause any condition contained in Section 7 or Exhibit B of the Merger Agreement to not be satisfied; and

(c) against the following actions (other than the Offer, the Merger and the transactions contemplated by the Merger Agreement): (i) any Acquisition Proposal; (ii) any change in a majority of the members of the board of directors of the Company, other than any change contemplated by Section 1.3 of the Merger Agreement; or (iii) any other action which is intended, or which would reasonably be expected, to impede, interfere with, delay, postpone, discourage or adversely affect the consummation of the Offer, the Merger or any of the other transactions contemplated by the Merger Agreement or this Stockholder Tender Agreement.

1.3 Proxy; Further Assurances. Contemporaneously with the execution of this Stockholder Tender Agreement, Stockholder shall execute and deliver to Parent a proxy in the form attached to this Stockholder Tender Agreement as Exhibit A, which shall be irrevocable to the fullest extent permitted by applicable Legal Requirements, with respect to the Subject Securities solely with respect to any item set forth in Sections 1.2(a), (b) or (c) (the “Proxy”).

(c) STOCKHOLDER AND PARENT IRREVOCABLY WAIVE THE RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY LEGAL PROCEEDING RELATING TO THIS STOCKHOLDER TENDER AGREEMENT OR THE PROXY OR THE ENFORCEMENT OF ANY PROVISION OF THIS STOCKHOLDER TENDER AGREEMENT OR THE PROXY.
