- 6 -

and affiliates do not, make any public announcement or public statements with respect to the transactions contemplated by this Agreement and the Definitive Agreement without the prior written approval of EHT.

12.EHT Acknowledgements. EHT agrees and acknowledges that the Securityholder is bound hereunder solely in his, her or its capacity as a securityholder of the Company and that the provisions of this Agreement shall not be deemed or interpreted to bind the Securityholder or any of its directors, officers or principal shareholder in his, her or its capacity as a director, officer or shareholder of the Company or any of its subsidiaries. For the avoidance of doubt, nothing in this Agreement shall limit or restrict any party from properly fulfilling his fiduciary duties as a director or officer of the Company.

13.Termination. Unless otherwise provided for herein, this Agreement shall terminate on the earliest of:

(a)EHT providing written notice of termination to the Securityholders;

(b)the termination of the Definitive Agreement in accordance with its terms;

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

16.No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in EHT any direct or indirect ownership or incidence of ownership at law or in equity with respect to any of the Securities or any right or entitlement to acquire or become the owner at law or in equity of the Securities.
