(a) to vote or to cause to be voted all of the Subject Securities entitled to vote, including any other such securities of the Company directly or indirectly acquired by or issued to the undersigned after the date hereof but prior to the record date for the Meeting, in favour of the approval of the Arrangement Resolution and any other matter necessary for the consummation of the transactions contemplated by the Arrangement Agreement (the “Transactions”);

(b) no later than ten (10) days prior to the Meeting, to deliver or to cause to be delivered to the Company duly executed proxies or voting instruction forms voting in favour of the approval of the Arrangement Resolution, to name in such proxies or voting instruction forms those individuals as may be designated by the Company in the Circular and such proxies or voting instruction forms not to be revoked or withdrawn without the prior written consent of the Purchaser;

Without limiting the provisions of the Arrangement Agreement, nothing contained in this Agreement shall in any way (i) limit or affect any actions the undersigned may take in his or her capacity as a director or officer of the Company or limit or restrict in any way the exercise of his or her fiduciary duties as director or officer of the Company or other legal obligation to act in the best interests of the Company or (ii) be construed to create any obligation on the part of the undersigned in his or her capacity as a director or officer of the Company to refrain from taking any action in his or her capacity as such.

3. The undersigned hereby represents and warrants that this Agreement has been duly executed and delivered and, assuming the due authorization, execution and delivery by the Purchaser, is a valid and binding agreement, enforceable against the undersigned in accordance with its terms, and the performance by the undersigned of its obligations hereunder will not constitute a violation or breach of or default under, or conflict with, any contract, commitment or agreement to which the undersigned is a party or by which the undersigned or any of his or her property or assets is bound at the time of such performance.

4. The Purchaser hereby represents and warrants, that:
