(4) This Section 4.8 shall survive the consummation of the Arrangement and is intended to be for the benefit of, and shall be enforceable by, the present and former directors and officers of the Corporation and its Subsidiaries and their respective heirs, executors, administrators and personal representatives (the “Indemnified Persons”) and shall be binding on the Purchaser, the Corporation and their respective successors and assigns, and, for such purpose, the Corporation hereby confirms that it is acting as agent on behalf of the Indemnified Persons.

Section 5.3 Responding to an Acquisition Proposal. (1) Notwithstanding Section 5.1, if at any time prior to obtaining the Required Shareholder Approval, the Corporation receives an unsolicited written Acquisition Proposal, the Corporation may (i) contact the Person making such Acquisition Proposal and its Representatives solely for the purpose of clarifying such Acquisition Proposal so as to determine whether such Acquisition Proposal constitutes or could reasonably be expected to constitute or lead to, a Superior Proposal, and (ii) engage in or participate in discussions or negotiations with such Person regarding such Acquisition Proposal, and may provide copies of, access to or disclosure of confidential information, properties, facilities, or Books and Records, provided that if and only if: (a) the Board first determines (based upon, inter alia, the recommendation of the Independent Committee) in good faith, after consultation with its financial advisors and its outside legal counsel, that such Acquisition Proposal constitutes, or would reasonably be expected to constitute, a Superior Proposal; (b) the Person making the Acquisition Proposal and its Representatives were not restricted from making such Acquisition Proposal pursuant to an existing confidentiality, standstill, non-disclosure, use, business purpose or similar restriction contained in any Contract entered into with the Corporation or any of its Subsidiaries;

- 41 - (c) the Corporation has been, and continues to be, in compliance with its obligations under this Article 5; (d) prior to providing any such copies, access, or disclosure, the Corporation enters into a confidentiality and standstill agreement with such Person that contains a customary standstill provision for not less than 12 months and that is otherwise on terms that are no less favourable to the Corporation than those found in the Confidentiality Agreement, and any such copies, access or disclosure provided to such Person shall have already been (or simultaneously be) provided to the Purchaser (by posting such information to the Data Room or otherwise); and (e) the Corporation promptly provides the Purchaser with: (i) prior written notice stating the Corporation’s intention to participate in such discussions or negotiations and to provide such copies, access or disclosure; (ii) prior to providing any such copies, access or disclosure, a true, complete and final executed copy of the confidentiality and standstill agreement referred to in Section 5.3(1)(d); and (iii) any material non-public information concerning the Corporation or its Subsidiaries provided to such other Person which was not previously provided to the Purchaser. (2) The Parties acknowledge that the furnishing of certain competitively sensitive information to competitors of the Corporation and of its Subsidiaries would be materially prejudicial to the Corporation and its Subsidiaries and, accordingly, no such information shall be disclosed to any Person that the Independent Committee, acting reasonably, determines to be a competitor of the Corporation or of any of its Subsidiaries under Section 5.3(1). Notwithstanding the foregoing, such information may be disclosed under Section 5.3(1) on a confidential basis to external advisors and experts retained by any such competitor of the Corporation or of its Subsidiaries, who enter into agreements reasonably satisfactory to the Corporation that such information will not be provided or communicated to the competitor, its officers, directors, financing sources or other Representatives. Section 5.4 Right to Match. (1) If the Corporation receives an Acquisition Proposal that constitutes a Superior Proposal prior to the approval of the Arrangement Resolution by the Shareholders, the Board may (based upon, inter alia, the recommendation of the Independent Committee), subject to compliance with Article 7 and Section 8.2, enter into a definitive agreement with respect to such Superior Proposal or withdraw or modify the Board Recommendation, if and only if: (a) the Person making the Superior Proposal was not restricted from making such Superior Proposal pursuant to an existing confidentiality, standstill, non-disclosure, use, business purpose or similar restriction with the Corporation or any of its Subsidiaries;

- 42 - (b) the Corporation has been, and continues to be, in compliance with its obligations under this Article 5; (c) the Corporation has delivered to the Purchaser a written notice of the determination of the Board that such Acquisition Proposal constitutes a Superior Proposal and of the intention of the Board to enter into such definitive agreement with respect to such Superior Proposal or withdraw or modify the Board Recommendation, together with a written notice from the Board regarding the value and financial terms that the Board, in consultation with its financial advisors, has determined should be ascribed to any non-cash consideration offered under such Superior Proposal (the “Superior Proposal Notice”); (d) the Corporation has provided the Purchaser a copy of the proposed definitive agreement for the Superior Proposal and all supporting materials, including any financing documents supplied to the Corporation in connection therewith; (e) at least five full Business Days (the “Matching Period”) have elapsed from the date that is the later of the date on which the Purchaser received the Superior Proposal Notice and the date on which the Purchaser received all of the materials set forth in Section 5.4(1)(d); (f) during any Matching Period, the Purchaser has had the opportunity (but not the obligation), in accordance with Section 5.4(2), to offer to amend this Agreement and the Arrangement in order for such Acquisition Proposal to cease to be a Superior Proposal; (g) after the Matching Period, the Board (i) has determined in good faith, after consultation with the Corporation’s outside legal counsel and financial advisors, that such Acquisition Proposal continues to constitute a Superior Proposal (if applicable, compared to the terms of the Arrangement as proposed to be amended by the Purchaser under Section 5.4(2)) and (ii) has determined in good faith, after consultation with its outside legal counsel, that the failure by the Board to recommend that the Corporation enter into a definitive agreement with respect to such Superior Proposal or withdraw or modify the Board Recommendation would be inconsistent with its fiduciary duties; (h) such Superior Proposal does not require the Corporation or any other Person to seek to interfere with the attempted successful completion of the Arrangement (including requiring the Corporation to delay, adjourn, postpone or cancel the Meeting) or provide for the payment of any break, termination or other fees or expenses or confer any rights or options to acquire assets or securities of the Corporation or any of its Subsidiaries to any Person in the event that the Corporation or any of its Subsidiaries completes the Arrangement; and (i) prior to or concurrently with entering into such definitive agreement or withdrawing or modifying the Board Recommendation, the Corporation terminates this Agreement pursuant to Section 7.2(3)(b) and pays the Corporation Termination Fee pursuant to Section 8.2.

- 43 - Section 5.4(1)(f) to amend the terms of this Agreement and the Arrangement in good faith in order to determine whether such proposal would, upon acceptance, result in the Acquisition Proposal previously constituting a Superior Proposal ceasing to be a Superior Proposal; and (b) the Corporation shall negotiate in good faith with the Purchaser to make such amendments to the terms of this Agreement or the Plan of Arrangement as would enable the Purchaser to proceed with the transactions contemplated by this Agreement on such amended terms. If the Board determines (based upon, inter alia, the recommendation of the Independent Committee) that such Acquisition Proposal would cease to be a Superior Proposal, the Corporation shall promptly so advise the Purchaser and the Corporation and the Purchaser shall amend this Agreement to reflect such offer made by the Purchaser, and shall take and cause to be taken all such actions as are necessary to give effect to the foregoing. (3) Each successive amendment or modification to any Acquisition Proposal that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by the Shareholders or other material terms or conditions thereof shall constitute a new Acquisition Proposal for the purposes of this Section 5.4, and the Purchaser shall be afforded a new full five Business Day Matching Period from the later of the date on which the Purchaser received the Superior Proposal Notice and the date on which the Purchaser received all of the materials set forth in Section 5.4(1)(d) with respect to the new Superior Proposal from the Corporation. (4) The Board shall promptly reaffirm the Board Recommendation (based upon, inter alia, the recommendation of the Independent Committee) by press release after any Acquisition Proposal which the Board has determined not to be a Superior Proposal is publicly announced or publicly disclosed or the Board determines that a proposed amendment to the terms of this Agreement or the Plan of Arrangement as contemplated under Section 5.4(2) would result in an Acquisition Proposal no longer being a Superior Proposal. The Corporation shall provide the Purchaser and its outside legal counsel with a reasonable opportunity to review and comment on the form and content of any such press release and shall make all reasonable amendments to such press release as requested by the Purchaser and its counsel. (5) If the Corporation provides a Superior Proposal Notice to the Purchaser on a date that is less than ten Business Days before the Meeting, the Corporation shall upon request from the Purchaser, acting reasonably, postpone the Meeting to a date that is not more than fifteen Business Days after the scheduled date of the Meeting, but in any event the Meeting shall not be postponed to a date which would prevent the Effective Date from occurring on or prior to the Outside Date. (6) Nothing contained in this Section 5.4 will limit in any way the obligation of the Corporation to convene and hold the Meeting in accordance with Section 2.3 of this Agreement while this Agreement remains in force. (7) Nothing contained in this Article 5 shall prohibit the Board (or the Independent Committee) from: (a) responding through a directors’ circular or otherwise as required by Law to an Acquisition Proposal that it determines is not a Superior Proposal, provided that the Corporation shall provide the Purchaser and its legal counsel with a reasonable opportunity to review the form and content of such circular or other disclosure; or

- 44 - (b) calling or holding a meeting of Shareholders requisitioned by Shareholders in accordance with the CBCA or taking any other action with respect to an Acquisition Proposal to the extent ordered or otherwise mandated by a court of competent jurisdiction in accordance with Law, provided that the Corporation provides at least ten Business Days’ notice to the Purchaser of the calling of such meeting of Shareholders.

Without limiting the generality of the foregoing, the Corporation shall advise its Subsidiaries and its Representatives of the prohibitions set out in this Article 5 and any violation of the restrictions set forth in this Article 5 by the Corporation, its Subsidiaries or their respective Representatives is deemed to be a breach of this Article 5 by the Corporation.

The Corporation irrevocably waives any right that it may have to raise as a defence that any such liquidated damages are excessive or punitive, including under article 1623 of the Civil Code of Québec. The Purchaser agrees that the payment of the Corporation Termination Fee pursuant to Section 8.2(3) in the manner provided therein is the sole and exclusive remedy of the Purchaser in respect of the event giving rise to such payment, provided, however, that this limitation shall not apply in the event of wilful breach or fraud by the Corporation.

In no event shall the Corporation be required to pay under Section 8.2(1), on the one hand, and this Section 8.4(2), on the other hand, in the aggregate, an amount in excess of the Corporation Termination Fee.

A Party may change its address for service from time to time by providing a notice in accordance with the foregoing. Any subsequent notice or other communication must be sent to the Party at its changed address. Any element of a Party’s address that is not specifically changed in a notice will be assumed not to be changed. Sending a copy of a notice or other communication to a Party’s outside 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 outside legal counsel does not invalidate delivery of that notice or other communication to a Party. Section 8.6 Time of the Essence. Time is of the essence in this Agreement. The mere lapse of time in the performance of the terms of this Agreement by any Party will have the effect of putting such Party in default in accordance with Articles 1594 to 1600 of the Civil Code of Québec. Section 8.7 Further Assurances. Subject to the provisions of this Agreement, the Parties will, from time to time, do all acts and things and execute and deliver all such further documents and instruments, as the other Parties may, either before the Effective Date, reasonably require to effectively carry out or better evidence or perfect the full intent and meaning of this Agreement and, in the event the Arrangement becomes effective, to document or evidence any of the transactions or events set out in the Plan of Arrangement.

- 55 - Section 8.8 Injunctive Relief. (1) The Parties agree that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to specific performance of the terms of this Agreement and an injunction or injunctions and other equitable relief to prevent breaches or threatened breaches of this Agreement, and to enforce compliance with the terms of this Agreement without any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief hereby being waived. (2) While the Corporation may pursue either a grant of specific performance under Section 8.8(1) to the extent provided therein or monetary damages, under no circumstances shall the Corporation be permitted or entitled to receive both (i) a grant of specific performance that permits the consummation of the transactions contemplated by this Agreement in accordance with the terms of this Agreement; and (ii) monetary damages in connection with this Agreement or any termination of this Agreement. Section 8.9 Guarantee. The Purchaser Parent hereby unconditionally and irrevocably guarantees on a solidary basis with the Purchaser in respect of any and all obligations by the Purchaser to pay any amounts payable by the Purchaser pursuant to this Agreement or perform any obligation hereunder.

Section 8.11 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.

- 56 - Section 8.12 Entire Agreement. This Agreement constitutes the entire agreement between the Parties with respect to the transactions contemplated by this Agreement 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. Section 8.13 Successors and Assigns. (1) This Agreement becomes effective only when executed by the Corporation and the Purchaser. After that time, it will be binding upon and enure to the benefit of the Corporation, the Purchaser and their respective successors and permitted assigns. (2) Neither this Agreement nor any of the rights or obligations under this Agreement are assignable or transferable by any Party without the prior written consent of the other Parties, except that the Purchaser may assign all or any portion of its rights and obligations under this Agreement to any of its affiliates, but none of any such assignments shall (i) relieve the Purchaser of its obligations hereunder, (ii) impair, delay or prevent the satisfaction of any other conditions set forth in Article 6, or (iii) impair, delay or prevent the consummation of the transactions contemplated by this Agreement. Section 8.14 Severability. If any provision of this Agreement is determined to be illegal, invalid or unenforceable by an arbitrator or 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. Section 8.15 Governing Law. (1) This Agreement will be governed by, interpreted and enforced in accordance with the Laws of the Province of Québec and the federal Laws of Canada applicable therein. (2) Each Party irrevocably attorns and submits to the non-exclusive jurisdiction of the Québec courts situated in the City of Montreal and waives objection to the venue of any proceeding in such court or that such court provides an inconvenient forum. Section 8.16 Rules of Construction. The Parties to this Agreement waive the application of any Law or rule of construction providing that ambiguities in any agreement or other document shall be construed against the Party drafting such agreement or other document.

- 57 - Section 8.17 No Liability. No director or officer of the Purchaser shall have any personal liability whatsoever to the Corporation under this Agreement or any other document delivered in connection with the transactions contemplated hereby on behalf of the Purchaser.
