In the event that, in lieu of or in conjunction with the Arrangement, the Purchaser seeks to complete the transactions contemplated in the Arrangement Agreement other than as contemplated by this Agreement and the Arrangement Agreement on a basis that (a) provides for economic terms which, in relation to the Securityholder, on an aftertax basis, are at least equivalent to or better than those contemplated by this Agreement and the Arrangement Agreement, (b) would not likely result in a delay or time to completion beyond the Outside Date, and (c) is otherwise on terms and conditions not materially more onerous on the Securityholder than the transactions contemplated in the Arrangement Agreement (any such transaction, an “ Alternative Transaction ”), then during the term of this Agreement the Securityholder may, on its own accord, and shall, upon written request of the Purchaser, support the completion of such Alternative Transaction in the same manner as the transactions contemplated in the Arrangement Agreement in accordance with the terms and conditions of this Agreement, including by (A) if applicable, depositing or causing the deposit of its Affected Securities, into an Alternative Transaction conducted by way of a take-over bid made by the Purchaser or an affiliate of Purchaser and not withdrawing them; and/ or (B) voting or causing to be voted all of the Affected Securities (to the extent that they carry the right to vote) in favour of, and not dissenting from (to the extent dissent rights are available under applicable law), such Alternative Transaction proposed by the Purchaser and, in the event of any such proposed Alternative Transaction, the references in this Agreement to the “Arrangement” shall be deemed to be changed to “Alternative Transaction” and all

(g) the Outside Date.

Any such termination of this Agreement in accordance with this Section 4.1 shall render the provisions of this Agreement of no further force and effect and no party shall have any further liability or obligations to any other party hereunder, provided however that such termination shall not prejudice the rights of a party as a result of a breach by any other party of its obligations hereunder occurring prior to such termination.

4.2 Time of the Essence

Time is of the essence in the performance of the parties’ respective obligations.

4.3 Amendment

This Agreement may, at any time and from time to time prior to the Effective Time, be amended by mutual written agreement of the parties hereto.

4.4 Equitable Relief

The parties hereby agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached, and that monetary damages or other legal remedies would not be an adequate remedy for any such damages. Accordingly, the parties acknowledge and hereby agree that in the event of any breach or threatened breach by the Securityholder of any of its covenants or obligations set forth in this Agreement, the Purchaser shall be entitled to an injunction or injunctions to prevent or restrain breaches of this Agreement by the Securityholder, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other under this Agreement. The Securityholder hereby agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches of this Agreement by it, and to specifically enforce the terms and provisions of this Agreement to prevent breaches of, or to enforce compliance with, the covenants and obligations of the other party under this Agreement. The parties further agree that (a) by seeking the remedies provided for in this Section 4.4, a party shall not in any respect waive its right to seek any other form of relief that may be available to a party under this Agreement in the event that this Agreement has been terminated or in the event that the remedies provided for in this Section 4.4 are not available or otherwise are not granted, and (b) nothing set forth in this Section 4.4 shall require any party to institute any proceeding for (or limit any party’s right to institute any proceeding for) specific performance under this Section 4.4 prior or as a condition to exercising any termination right under Section 4.1 or pursuing damages after such termination, nor shall the commencement of any legal proceeding restrict or limit any party’s right to terminate this Agreement in accordance with the terms of Section 4.1 or pursue any other remedies under this Agreement that may be available then or thereafter.

4.5 Fiduciary Duties

The Purchaser agrees and acknowledges that the Securityholder is bound hereunder solely in his or her capacity as a shareholder 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 shareholders in his or her capacity as a director or officer of 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 or her fiduciary duties as a director or officer of the Company.

4.6 Waiver

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the party to be bound by the waiver. A party’s failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a party from any other or further exercise of that right or the exercise of any other right.

4.7 Entire Agreement

This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written, of the parties. There are no representations, warranties, covenants, conditions or other agreements, express or implied, collateral, statutory or otherwise, between the parties in connection with the subject matter of this Agreement, except as specifically set forth in this Agreement.

Sending a copy of a notice or other communication to a party’s legal counsel as contemplated above is for information purposes only and does not constitute delivery of the notice or other communication to that party. The failure to send a copy of a notice or other communication to legal counsel does not invalidate delivery of that notice or other communication to a party.

4.9 Severability

If any provision of this Agreement is determined to be illegal, invalid or unenforceable by any court of competent jurisdiction, that provision will be severed from this Agreement and the remaining provisions shall remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

4.10 Successors and Assigns

The provisions of this Agreement shall be binding upon and enure to the benefit of the parties hereto and their respective successors, permitted assigns and legal personal representatives, provided that no party may assign, delegate or otherwise transfer any of its rights, interests or obligations under this Agreement without the prior written consent of the other parties hereto, provided that the Purchaser may assign all or part of its right under this Agreement to, and its obligations under this Agreement may be assumed by, any of its affiliates, provided that if such agreement and/or assumption takes place, the Purchaser shall continue to be liable jointly and severally with such affiliate, as the case may be, for all of its obligations hereunder, without the consent of the Securityholder.

4.14 Counterparts

This Agreement may be executed in any number of counterparts (including counterparts by facsimile) and all such counterparts taken together shall be deemed to constitute one and the same instrument.
