3. Control over Corporation or Trust. If any of the Subject Shares are held through a corporation or trust over which the Shareholder has control, within the meaning of the Securities Act (either alone or in conjunction with any other person), the Shareholder shall act, vote, and exercise its power and authority to ensure that this Agreement is complied with by such corporation or trust.

4. Covenants, Representations and Warranties of Acquiror. Acquiror represents and warrants that it is duly authorized to execute and deliver this Agreement and this Agreement is a valid and binding agreement enforceable by the Shareholder in accordance with its terms, subject to the usual exceptions as to bankruptcy, insolvency, reorganization, moratorium, and other laws relating to or affecting creditors’ rights generally and the availability of equitable remedies. Acquiror further represents and warrants that the execution and delivery of this Agreement and the fulfilment of the terms hereof by Acquiror does not and will not result in a breach of any agreement or instrument to which it is a party or by which it is contractually bound. Acquiror covenants to comply, and to cause Merger Sub to comply, with the terms of the Merger Agreement.

5. Termination. Unless otherwise provided for herein, this Agreement and the parties’ rights and obligations hereunder shall terminate and be of no further force or effect, and there shall be no obligation or further liability on the part of the Shareholder or the Acquiror hereunder, upon the earlier of: (i) the mutual written consent of the Acquiror and the Shareholder; (ii) without any further action by the Shareholder or the Acquiror, the Effective Time (as defined in the Merger Agreement); (iii) the time at which the Merger Agreement is terminated in accordance with its terms; (iv) the time at which the Board of Directors of the Company makes a Change of Recommendation in conformity with the provisions of Section 5.4(e) of the Merger Agreement; or (v) the time at which the Merger Agreement is amended to (A) decrease the Merger Consideration (as defined in the Merger Agreement) from that set forth in the Merger Agreement at the date hereof, or (B) change the form of the Merger Consideration from that set forth in the Merger Agreement at the date hereof; provided, however, that no such termination of this Support Agreement shall relieve any party hereto from any liability for any breach of this Support Agreement prior to such termination.

6. Impact on Fiduciary Obligations. Nothing contained in this Agreement shall be construed to restrict any affiliate of the Shareholder (within the meaning of the Securities Act) from taking any action or refraining from taking any action in his or her capacity as a director or officer of the Company, and no such action taken by any such person shall be deemed to be a breach or violation by the Shareholder of its obligations under this Agreement.

7. Specific Performance. The Shareholder acknowledges that it may not be possible to measure in money the damage to Acquiror if the Shareholder fails to comply with any of its obligations under this Agreement, that every such obligation may be material and that, in the event of any such failure, Acquiror may not have an adequate remedy at law or in damages, and accordingly, the Shareholder agrees that the issuance of an injunction or other equitable remedy may be the appropriate remedy for any such failure.

8. Successors and Assigns. This Agreement and all obligations of the Shareholder hereunder shall be binding upon and shall enure to the benefit of the parties hereto and their respective successors and assigns.

9. Entire Agreement. This Agreement supersedes all prior agreements between the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof. This Agreement may not be modified or waived, except expressly by an instrument in writing signed by all the parties hereto. No waiver of any provision hereof by any party shall be deemed a waiver by any other party nor shall any such waiver be deemed a continuing wavier of any matter by such party.
