(b) The Shareholder shall not, directly or indirectly during the period from the date of this Agreement through the Expiration Date, deposit (or permit the deposit of) any of its Shares in a voting trust or grant any proxy or enter into any voting agreement or similar agreement in contravention of the obligations of the Shareholder under this Agreement with respect to any such Shares.

(c) The Shareholder shall not take any action that would (i) make any representation or warranty by the Shareholder in this Agreement to be untrue or incorrect; or (ii) have the effect of impairing the ability of the Shareholder to perform its obligations under this Agreement or preventing or delaying the consummation of any of the transactions contemplated hereby.

Any such vote shall be cast (or consent shall be given) by the Shareholder in accordance with such procedures relating thereto so as to ensure that it is duly counted, including for purposes of determining that a quorum is present and for purposes of recording the results of such vote (or consent). Except as contemplated by this Agreement, the Shareholder (a) has not entered into, and shall not enter into at any time while this Agreement remains in effect, any voting agreement or voting trust with respect to its Shares that would prohibit, undermine, limit or otherwise adversely affect its compliance with its obligations pursuant to this Agreement, and (b) has not granted, and shall not grant at any time while this Agreement remains in effect, a proxy or power of attorney with respect to its Shares, in either case, which is inconsistent with its obligations pursuant to this Agreement.

For purposes of this Section 4(a), “willful breach” shall mean an act or failure to act of such person with the actual knowledge that the taking of such act or the failure to take such act would constitute a material breach of this Section 4(a).

(b) Nothing in this Agreement shall restrict or limit the ability of any Person who is an officeholder or director of the Company (including, as applicable, any officeholder or director of the Company who is an Affiliate of the Shareholder) to take any action solely in his or her capacity as an officeholder or director of the Company to the extent expressly permitted by the Merger Agreement and none of such actions in such capacity shall be deemed to constitute a breach of this Agreement. Nothing contained in this Agreement shall be deemed to vest in Parent or any other Person any direct or indirect ownership or incidence of ownership of or with respect to any Shares. All rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Shareholder, and neither Parent nor any other Person shall have any authority to exercise any power or authority to direct the Shareholder in the voting of any of its Shares, except as otherwise specifically provided herein.

(a) the Shareholder is the owner, or otherwise entitled to direct the voting, of the Shares indicated under the Shareholder’s name on the signature page of this Agreement, and such Shares are free and clear of any Liens or adverse claims (except for such Liens arising under securities laws or for such Liens or adverse claims as would not prohibit, limit or otherwise conflict with the Shareholder’s compliance with its obligations pursuant to this Agreement).

(c) No proxies or voting instructions relating to the Merger have been heretofore given or will be given in respect of the Shares.

6. Additional Documents.

Without limiting the generality or effect of the foregoing or any other obligation of the Shareholder hereunder, the Shareholder hereby authorizes Parent to deliver a copy of this Agreement to the Company and hereby agrees that the Company may rely upon such delivery as conclusively evidencing the agreements and understandings set forth herein and therein. Prior to the Expiration Date, the Shareholder shall notify Parent promptly in writing of the acquisition of ownership of additional Shares by it or for its account after the date hereof, if any. Without limiting the foregoing, in the event of any share split, share dividend, reclassification, recapitalization or other change in the capital structure of the Company affecting the Shares, the number of Shares constituting the Shareholder's Shares shall be adjusted appropriately and this Agreement and the obligations hereunder shall attach to any additional securities issued with respect to or in exchange for such Shares.

Shareholder shall not issue any press release or make any other public statement or other public disclosure with respect to this Agreement, the Merger Agreement or the transactions contemplated hereby or thereby without the prior written consent of Parent, except as may be required of the Shareholder by applicable Law and, where such requirement under applicable Law arises, after giving Parent opportunity as practicable in the circumstances to comment on any such press release or statement and including therein such of Parent’s comments accepted by the Shareholder in its reasonable discretion. Notwithstanding the foregoing, without prior consent of Parent, the Shareholder may disseminate material substantially similar to material included in a press release or other document previously approved for public distribution by Parent.

9. Termination. This Agreement shall terminate and shall have no further force or effect as of the Expiration Date, provided that the Shareholder may terminate this Agreement by written notice to Parent in the event of an amendment of the Merger Agreement that materially adversely changes the economic rights of the Company's shareholders under the Merger Agreement (including, without limitation, any reduction in the Merger Consideration per Share, any extension of the Outside Date by more than 30 days and any increase in the Termination Fee), without the Shareholder's prior written consent thereto; provided, however, that Section 10 shall survive any termination of this Agreement; and provided, further, that, subject to Section 4(a), the termination of this Agreement shall not relieve the Shareholder from any liability for any willful breach of this Agreement.
