Section 6. Specific Performance; Remedies. Stockholder acknowledges that it is a condition to the willingness of Purchaser to enter into the Merger Agreement that Stockholder execute and deliver this Agreement and that it will be impossible to measure in money the damage to Purchaser if Stockholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, Purchaser will not have an adequate remedy at law or in equity.

Stockholder further agrees that Stockholder will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with Purchaser’s seeking or obtaining such equitable relief. In addition, after discussing the matter with Stockholder, Purchaser shall have the right to inform any third party that Purchaser reasonably believes to be, or to be contemplating, participating with Stockholder or receiving from Stockholder assistance in violation of this Agreement, of the terms of this Agreement and of the rights of Purchaser hereunder, and that participation by any such persons with Stockholder in activities in violation of Stockholder’s agreement with Purchaser set forth in this Agreement may give rise to claims by Purchaser against such third party.

Section 7. Term of Agreement; Termination. The term of this Agreement (the “Term”) shall begin on the date hereof and shall end on the earlier to occur of (a) the Effective Time, (b) such date and time as the Merger Agreement shall be terminated pursuant to Article VII thereof, or (c) upon mutual written agreement of the parties to terminate this Agreement. Stockholder shall have the right to terminate this Agreement if the Merger Agreement is amended to decrease the Merger Consideration, provided that Stockholder sends notice to Purchaser of Stockholder’s election to terminate within three (3) Business Days after the public announcement of such amendment, in which case the term of this Agreement shall end on the date Purchaser receives such notice. Upon termination or expiration, no party shall have any further obligations or liabilities hereunder.

Section 8. Entire Agreement; Amendments.

This Agreement may not be amended, supplemented or modified, and no provisions hereof may be modified or waived, except by an instrument in writing signed by each party hereto, expressly stating an intention to amend this Agreement. No waiver of any provision hereof by either party shall be deemed a waiver of any other provision hereof by any such party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such party.

Section 9. Severability. In the event that any one or more provisions of this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, by any court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provisions of this Agreement and the parties shall use their reasonable efforts to substitute a valid, legal and enforceable provision which, insofar as practical, implements the purposes and intents of this Agreement.

Section 10. Further Assurances. Stockholder shall, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further consents, documents and other instruments as Purchaser may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement.
