At the reasonable request of Parent from time to time, the Company shall provide Parent with a list (in both written and electronic form) of the registered Shareholders, together with their addresses and respective holdings of Company Shares, with a list of the names and addresses and holdings of all Persons having rights issued by the Company to acquire Company Shares (including Optionholders and registered Warrantholders) and a list of non-objecting beneficial owners of Company Shares or Warrants, together with their addresses and respective holdings of Company Shares or Warrants.

To the extent that amounts are so deducted and withheld and paid to the appropriate Governmental Entity directly or indirectly by the Company, Parent, Subco or one or more Subsidiaries of Parent or the Depositary, as the case may be, such deducted and withheld amounts shall be treated for all purposes of this Agreement and the Plan of Arrangement as having been paid to the Shareholders, Optionholders or Warrantholders, as the case may be, in respect of which such deduction and withholding was made by the Company, Parent, Subco, one or more Subsidiaries of Parent or the Depositary, as the case may be, provided that such withheld amounts are actually remitted to the appropriate Governmental Entity within the time required and in accordance with the Tax Act or any other provision of domestic or foreign (whether national, federal, provincial, state, local or otherwise) Applicable Law relating to Taxes.

1.11 Alternative Transaction Structure. At the request of Parent, the Company shall use commercially reasonable efforts to assist Parent to successfully implement and complete any alternative transaction structure that: (a) does not have negative financial consequences to the Company and its Subsidiaries in any material respect, would provide Shareholders, Optionholders and Warrantholders with cash consideration not less than the

cash consideration per security receivable under Section 1.13 herein and would provide for the acquisition of all of the outstanding Company Shares, Options and Warrants; (b) would reasonably be expected to be completed prior to the Outside Date; and (c) is otherwise on terms and conditions no more onerous in any material respect than the Arrangement and this Agreement. In the event that the transaction structure is so modified, the relevant provisions of this Agreement shall be modified as necessary in order that they shall apply with full force and effect, mutatis mutandis, but with the adjustments necessary to reflect the revised transaction structure, and the parties hereto shall execute and deliver an agreement in writing giving effect to and evidencing such amendments as may be reasonably required as a result of such modifications and adjustments.

1.12 Closing.

1.13 Consideration. The Articles of Arrangement shall provide that the Shareholders, Optionholders and Warrantholders shall receive the following consideration:

(b) for each Option outstanding as of the Effective Time, a cash payment equal to the product of (i) the excess, if any, of the Share Consideration over the exercise price per share of such Option, multiplied by (ii) the number of Company Shares issuable upon exercise of such Option (with the aggregate amount rounded down to the nearest cent); and

(c) for each Warrant outstanding as of the Effective Time, a cash payment equal to the product of (i) the excess, if any, of the Share Consideration over the exercise price per share of such Warrant, multiplied by (ii) the number of Company Shares issuable upon exercise of such Warrant (with the aggregate amount rounded down to the nearest cent).

If between the date of this Agreement and the Effective Time, the outstanding Company Shares shall have been changed into a different number of shares or a different class, by reason of any stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or any similar event, the Share Consideration and any other amounts payable pursuant to this Agreement shall be correspondingly adjusted to the extent appropriate to reflect such stock dividend, subdivision, reclassification, recapitalization, split, combination or exchange of shares or similar event.

The Company will immediately cease, and will cause its Subsidiaries and Agents immediately to cease, any and all existing activities, discussions or negotiations with any third parties conducted heretofore with respect to (or reasonably likely to lead to) any Third Party Proposal. “Third Party Proposal” means any Contract, proposal or offer (including any proposal or offer to the Shareholders) with respect to a proposed or potential Acquisition Transaction. “Acquisition Transaction” means: (A) any sale, lease or other disposition, direct or indirect (and however structured), of any business or assets of the Company and/or any of its Subsidiaries (which business or assets represent 15% or more of the consolidated revenues, net income or assets of the Company and its Subsidiaries, taken as a whole), (B) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in a third party beneficially owning 15% or more of any class of securities of the Company, (C) a merger, amalgamation, arrangement, consolidation, share exchange, business combination, reorganization, joint venture, recapitalization, liquidation, dissolution or other similar transaction involving the Company and/or any of its Subsidiaries (which Subsidiaries represent 15% or more of the consolidated revenues, net income or assets of the Company and its Subsidiaries, taken as a whole), (D) the issuance, sale or other disposition, direct or indirect (and however structured), of securities (or securities or other rights convertible into, or exercisable or exchangeable for, such securities) representing 15% or more of the voting power or capital stock of the Company and/or any of its Subsidiaries (which Subsidiaries represent 15% or more of the consolidated revenues, net income or assets of the Company and its Subsidiaries, taken as a whole) or (E) any combination of the foregoing (other than the Arrangement or any other transaction by or on behalf of Parent or Subco).

(b) Notwithstanding any other provision of this Agreement, prior to approval of the Arrangement Resolution by the Shareholders, in response to an unsolicited bona fide written Third Party Proposal made after the date hereof that the Board determines in good faith (after receiving the advice of its financial advisors and outside counsel) constitutes or is reasonably likely to lead to a Superior Proposal, the Company may, after giving Parent prompt notice of such determination, (i) furnish information with respect to the Company and its Subsidiaries to the Person making such Third Party Proposal (and its Representatives) pursuant to a confidentiality and standstill agreement on

terms no less favourable to the Company than those contained in the Confidentiality Agreement and containing additional provisions that expressly permit the Company to comply with the terms of this Section 4.3 (a copy of which confidentiality agreement shall be promptly (and in all events within 24 hours) provided for informational purposes only to Parent); provided, that (A) prior to providing any information or data to any Person or entering into discussions or negotiations with any Person, the Company notifies Parent promptly of any such inquiry, proposal or offer received by, any such information requested from, or any such discussions or negotiations sought to be initiated or continued with, the Company or any of its officers, directors, Employees, advisors and agents indicating, in connection with such notice, the material terms and conditions of the Third Party Proposal, the identity of the Person making such Third Party Proposal and provides a copy of any written Third Party Proposal and (B) all such information (to the extent such information has not been previously provided or otherwise made available to Parent) is provided or made available to Parent, as the case may be, substantially concurrent with the time it is provided or made available to such Person, as the case may be, and (ii) participate in discussions or negotiations with the Person making such Third Party Proposal (and its Representatives) regarding such Third Party Proposal; provided, that the Company shall keep Parent reasonably informed, on a prompt basis, of the status and material terms of any such proposals or offers and the status of any such discussions or negotiations and will notify Parent promptly of any determination by the Board that a Superior Proposal has been made. For purposes of this Agreement, a “Superior Proposal” means an unsolicited written bona fide Third Party Proposal pursuant to which a Person or Persons (or their stockholders) would own, if consummated, all of the outstanding capital stock of the Company (or of the surviving entity in a merger or the direct or indirect parent of the surviving entity in a merger) or all or substantially all of the assets of the Company and its Subsidiaries taken as a whole on terms that the Board determines, in its good faith judgment, after consultation with its financial advisors, that such Third Party Proposal (i) is not subject to any financing conditions or, if any financing is required, financing satisfactory to the Company is committed, (ii) is more favourable to the Shareholders from a financial point of view than the terms of the Arrangement, and (iii) without regard to any support agreement between the Parent and any Shareholder, is reasonably likely to be completed on the terms proposed.

(c) Neither the Board nor any committee thereof shall fail to make or withdraw, amend, change, modify or qualify in a manner adverse to Parent or Subco, or propose publicly to withdraw, amend, change, modify or qualify in a manner adverse to Parent or Subco, the approval, recommendation or declaration of advisability by the Board or any such committee of this Agreement or the Arrangement, or recommend, or propose publicly to recommend, the approval or adoption of any Third Party Proposal, or resolve or agree to take any such action (each, a “Change of Recommendation”), unless all of the following conditions are satisfied:

(iii) the Company shall have provided at least five Business Days’ prior written notice (the “Notice Period”) to Parent stating (A) that it has received a Superior Proposal, (B) the terms and conditions of such Superior Proposal, the identity of the Person making such Superior Proposal (and including a copy of all documentation containing or related to such Superior Proposal) and (C) that it intends to effect a Change of Recommendation and the manner in which it intends to do so and in the event that the Company Meeting is to be held within such Notice Period, the Company Meeting will be adjourned to a date not later than five Business Days after the expiry of the Notice Period;

(iv) Parent shall not have, within the Notice Period, made an offer that the Board by a majority vote determines in its good faith judgment (based on the written advice of its financial advisor) to be at least as favourable to the Company and the Shareholders as such Superior Proposal (it being agreed that the Board shall convene a meeting to consider any such offer by Parent promptly following the receipt thereof);

(v) the Board concludes in good faith, after receiving the advice of its outside legal counsel, that, in light of such Superior Proposal, the failure of the Board to effect a Change of Recommendation would be inconsistent with its fiduciary obligations to the Company under Applicable Law; and

(vi) the Company shall not have breached any of the provisions set forth in this Section 4.3.

(d) The Company acknowledges and agrees that each successive modification of any Superior Proposal shall constitute a new Superior Proposal for the purposes of this Section 4.3 and shall initiate a new Notice Period.

(e) Nothing in this Agreement shall prevent the Board from responding through a directors’ circular or otherwise as required by applicable Securities Laws to a Third Party Proposal that it determines is not a Superior Proposal.

4.4 Cooperation Regarding Reorganization. The Company shall, and shall cause each of its Subsidiaries to, cooperate with Parent and Subco in structuring, planning and implementing any reorganization (including for Tax purposes) of their respective capital, assets and corporate structure or such other planning as Parent and Subco may reasonably require provided, however, that (i) such reorganization not take place until such time as the parties agree, acting reasonably, that the Arrangement is likely to be completed on the terms and conditions contemplated, (ii) such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries, and (iii) Parent and Subco shall pay the implementation costs and any direct or indirect costs and liabilities, fees, damages, penalties, Taxes and other amounts that may be incurred as a consequences of the implementation of or to unwind, any such transaction if the Arrangement is not completed, including actual out-of-pocket costs and expenses for filing fees and external counsel and auditors which may be incurred.

(a) The Company shall not take any action or enter into any transaction, or permit any of its Subsidiaries to take any action or enter into any transaction, which would, or which reasonably may be expected to (i) render any representation or warranty made by it in this Agreement inaccurate, (ii) result in a breach of any of its covenants or obligations under this Agreement, or (iii) cause any condition in Section 7.1 or 7.2 to become incapable of satisfaction or materially more difficult to satisfy, or (iv) render the transactions contemplated by this Agreement incapable of completion or more difficult to complete.

(b) The Company shall promptly notify Parent orally and in writing of the occurrence of (i) any Company Material Adverse Effect, (ii) any material governmental or third party complaints, investigations or hearings (or communications indicating that the same are being contemplated), or (iii) any material communications with respect to labour union or collective bargaining matters or any material developments in relation to the foregoing, and the Company shall consult with Parent in respect of any matters relating to the foregoing.

(c) The Company shall execute and deliver, or cause to be executed and delivered, at the Closing such customary agreements, certificates, resolutions and other closing documents as may be reasonably requested by Parent.

(d) The Company shall use its reasonable best efforts to maintain the listing of the Company Shares and the Warrants on the TSX until the Effective Date and shall cooperate with Parent and shall use reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under Applicable Law and the rules and policies of the TSX to enable the delisting by the Company of the Company Shares and the Warrants from the TSX after the Effective Date.

(e) The Company shall, and shall cause the Subsidiaries to, advise Parent forthwith in writing of any transaction or event occurring after the date hereof, to the extent known to the Company or a Subsidiary, that could reasonably be expected to prevent Subco and its successors from obtaining a full increase in Tax cost pursuant to paragraphs 88(1)(d), 98(3)(c) or 98(5)(c) of the Tax Act that may otherwise be available to Subco and its successors in respect of non-depreciable capital property owned by the Company or a Subsidiary at the Effective Time.

(a) From and after the Effective Time, Parent and Subco shall cause the Company to, to the fullest extent permitted by Applicable Law, indemnify, defend and hold harmless, and provide advancement of expenses to, each Person who is now or who becomes prior to the Effective Time, an officer, director or Employee of the Company or

any of its Subsidiaries (the “Indemnified Parties”) against all losses, claims, damages, costs, expenses, liabilities or judgments or amounts that are paid in settlement of or in connection with any claim or Action that is based in whole or in part on, or arises in whole or in part out of, the fact that such Person is or was a director, officer or Employee of the Company or any of its Subsidiaries, and pertaining to any matter existing or occurring, or any acts or omissions occurring, at or prior to the Effective Time, whether asserted or claimed prior to, or at or after, the Effective Time (including matters, acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby) to the same extent such Persons are entitled to be indemnified or have the right to advancement of expenses as of the date of this Agreement by the Company or any of its Subsidiaries pursuant to the articles of incorporation and bylaws of such entity and indemnification agreements of the Company and its Subsidiaries, if any, in existence on the date hereof with any directors, officers and Employees of the Company and its Subsidiaries.

(b) Parent shall obtain prior to the Effective Time a prepaid “tail” insurance policy with a claims period of six years from the Effective Time with respect to directors’ and officers’ liability or fiduciary liability insurance covering each person covered by the Company’s directors’ and officers’ liability or fiduciary liability insurance policy for act or omissions occurring prior to the Effective Time on terms that are no less favourable that those of such policy of the Company in effect on the date of this Agreement; provided that if the aggregate annual premiums for such policies at any time during such period exceed 200% of the amount paid by the Company in respect of its last full fiscal year, which amount is set forth in Schedule 5.1(b) of the Company Disclosure Letter, Parent shall be required to provide such coverage as will then be available at an annual premium equal to 200% of such rate.

(c) This Section 5.1 is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and their heirs and personal representatives and shall be binding on Parent, Subco and the Company and their respective successors and assigns.

(d) In the event the Company or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made so that the successors and assigns of the Company honour the indemnification obligations set forth in this Section 5.1.

(e) The parties constitute the Company as trustee for the Indemnified Parties of the rights and benefits of this Section 5.1 and the Company accepts such trust and agrees to hold the rights and benefits of this Section 5.1 in trust for and on behalf of the Indemnified Parties. The obligations of Parent and Subco under this Section 5.1 shall not be terminated or modified in such a manner as to adversely affect the rights of any indemnified party to whom this Section 5.1 applies unless (i) such termination or modification is required by Applicable Law or (ii) the affected Indemnified Party shall have consented in writing to such termination or modification.

(a) Except as otherwise provided in this Agreement, neither Parent nor Subco shall take any action or enter into any transaction, which would, or which reasonably may be expected to (i) render any representation or warranty made by Parent in this Agreement inaccurate, (ii) result in a breach of any of Parent’s or Subco’s covenants or obligations under this Agreement, (iii) cause any condition in Section 7.1 or 7.3 to become incapable of satisfaction or materially more difficult to satisfy or (iv) render the transactions contemplated by this Agreement incapable of completion or more difficult to complete.

(b) Parent unconditionally and irrevocably guarantees the due and punctual performance by Subco of its obligations under this Agreement and the Plan of Arrangement and undertakes to perform such obligations to the extent that Subco fails to do so.

(a) Each of the Company, Parent and Subco shall promptly apply for, and take all reasonably necessary actions to obtain or make, as applicable, all Authorizations, Orders, declarations, submissions and filings with, and notices to, any Governmental Entity required to be obtained or made by it for the consummation of the transactions contemplated hereby. Each party shall cooperate with and promptly furnish information to the other parties necessary in connection with any requirements imposed upon such other parties in connection with the consummation of the Arrangement. Without limiting the generality of the foregoing, each of the Company and Parent shall, as promptly as practicable and before the expiration of any relevant legal deadline, but in no event later than 10 Business Days following the execution and delivery of this Agreement, file (i) a long form notification pursuant to Part IX of the Canadian Competition Act, (ii) the notification and report form required for the Arrangement and the transactions contemplated hereby pursuant to the HSR Act, (iii) any supplemental information requested or considered by Parent to be desirable to be submitted in connection with obtaining Competition Act Approval and the review of the transactions contemplated hereby pursuant to the HSR Act, and (iv) with any other Governmental Entity, any other filings, reports, information and documentation required for the consummation of the Arrangement and the transactions contemplated hereby pursuant to the Investment Canada Act or any Other Antitrust Laws.

(b) Each of the Company and Parent shall furnish to each other’s counsel such information and reasonable assistance as the other may request in connection with its preparation of any filing or submission that may be necessary or considered desirable by Parent in connection with (i) obtaining Competition Act Approval or Investment Canada Act Approval, or (ii) the HSR Act and any Other Antitrust Laws.

(c) Each of the Company and Parent shall use its reasonable best efforts to obtain promptly Competition Act Approval and any clearance or approval required under the Investment Canada Act, the HSR Act and any Other Antitrust Laws for the consummation of the Arrangement and the transactions contemplated hereby. Each of the Company and Parent shall keep the other apprised of the status of any communications with, and any inquiries or requests for additional information from any Governmental Entities and shall comply promptly with any such inquiry or request. Each of the Company and Parent shall give the other reasonable prior notice of any communication with, and any proposed understanding or agreement with, any Governmental Entity regarding any Authorizations, Orders, responses to information requests, declarations and filings with, and notices to, any Governmental Entity, and permit the other to review and discuss in advance, and consider in good faith the views of the other in connection with, any proposed communication, understanding or agreement with any Governmental Entity with respect to the Arrangement and the transactions contemplated by this Agreement. Notwithstanding the foregoing or any other provision of this Agreement, (i) Parent shall not be required to (A) consent to the divestiture, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any of its or its Affiliates’ assets or any assets of the Company or any of its Subsidiaries or (B) regarding antitrust matters, consent to any other structural or conduct remedy or enter into any settlement or agree to any Order respecting the transactions contemplated by this Agreement, and (ii) neither Parent nor any of its Affiliates shall have any obligation to contest, administratively or in court, any ruling, order or other action of any Governmental Entity or any other Person respecting the transactions contemplated by this Agreement; provided, that each of the Company and Parent shall both promptly respond to any Governmental Entity with respect to any request for additional information.

(d) Each of the Company and Parent shall instruct their respective counsel to cooperate with each other and use reasonable best efforts to facilitate and expedite the identification and resolution of any issues arising under the Canadian Competition Act, the Investment Canada Act, the HSR Act and the Other Antitrust Laws, the approval of the Arrangement under the Canadian Competition Act and the Investment Canada Act and the expiration of the applicable HSR Act waiting period and any waiting periods under the Other Antitrust Laws at the earliest practicable dates. Such reasonable efforts and cooperation include counsel’s undertaking (i) to keep each other appropriately informed of communications from and to personnel of the reviewing Governmental Entity, and (ii) to confer with each other regarding appropriate contacts with and response to personnel of any Governmental Entity. Notwithstanding the foregoing, counsel to Parent shall have the primary responsibility for contacting and communicating with the Commissioner, the Minister responsible for the Investment Canada Act, the U.S. Department of Justice and U.S. Federal Trade Commission and government authorities responsible for Other Antitrust Laws, in connection with the satisfaction of conditions set forth in Sections 7.1(c), 7.1(d) and 7.1(e).

6.2 Public Announcements. The initial press release relating to this Agreement shall be a joint press release the text of which has been agreed to by each of Parent and the Company. Thereafter, neither Parent nor the Company shall issue or cause the publication of any press release or otherwise make any public statements with respect to this Agreement, the Arrangement or the transactions contemplated by this Agreement without the prior consent of the other parties (such consent not to be unreasonably withheld, conditioned or delayed); provided, that a party may, without such consent (but after prior consultation to the extent practicable in the circumstances), issue such press releases and make such public statements that it believes are required by Applicable Law or the rules of the TSX or the New York Stock Exchange. Notwithstanding the foregoing, each of Parent and the Company may make any public statement in response to questions from the press, analysts, investors or those attending industry conferences or financial analyst conference calls, make presentations at such conferences and conference calls and make internal announcements to employees, so long as such statements and announcements are consistent with previous press releases, public disclosures or public statements made jointly by the Company and Parent (or individually, if approved by the other party).

(d) any inaccuracy of any representation or warranty contained in this Agreement at any time during the term hereof that could reasonably be expected to cause the conditions set forth in Article VII not to be satisfied; and

(B) the Board shall effect a Change of Recommendation or publicly propose to do so.

8.3 Remedies. Any material breach by a party of any of its representations, warranties, covenants or agreements set forth in this Agreement that is wilful or intentional shall not be affected by termination of this Agreement or any payment of the Termination Fee. The parties agree that if Subco or Parent fail to deliver or arrange to be delivered any cash amounts to the Depositary or the Company, as and when required by the Plan of Arrangement, and all of the conditions set forth in Sections 7.1 and 7.2 have been satisfied or waived (other than any deliveries to be made, and actions to be taken, as at the Effective Time), such failure will be deemed to be a wilful and intentional material breach of this Agreement by each of Subco and Parent.

(a) The Company shall pay Parent, by wire transfer of immediately available funds to an account designated by Parent, a fee of $26,000,000 (the “Termination Fee”) if this Agreement is terminated as follows:

(i) if Parent terminates this Agreement pursuant to Section 8.1(a)(iii)(B), the Company shall pay Parent the Termination Fee in full on the date of such termination provided that the Termination Fee will not be payable if, notwithstanding the occurrence of a Change of Recommendation, the Arrangement Resolution has been approved and the Final Order has been obtained on terms and conditions contemplated by this Agreement; or

(ii) if (x) this Agreement is terminated pursuant to Section 8.1(a)(ii)(A) or (C), (y) at any time after the date of this Agreement and at or before the date of such termination a proposal with respect to an Acquisition Transaction shall have been publicly announced or disclosed, and (z) within twelve (12) months after the date of such termination (A) the Company shall have consummated an Acquisition Transaction or (B) entered into an agreement with respect to an Acquisition Transaction and such Acquisition Transaction is subsequently completed, within twelve (12) months after such termination, then, in any such case in (A) or (B), the Company shall promptly on the date of the consummation of any such Acquisition Transaction pay Parent the Termination Fee. When used in this Section 8.4(a)(ii) only, the term “Acquisition Transaction” shall have the meaning assigned to such term in Section 4.3(a), except the reference to “15% or more” in the definition of “Acquisition Transaction” shall be deemed to be a reference to “more than 50%”.

(b) In the event that the Company fails to pay the Termination Fee when due, the Company will also pay the costs and expenses of Parent or Subco in connection with a legal action to enforce this Agreement, together with interest on such Termination Fee, commencing on the date that such Termination Fee became due, at a rate equal to 8% per annum.

Subject to applicable escheat laws, any amounts deposited with the Depositary for the payment of the Aggregate Share Consideration, the Aggregate Warrant Consideration or the Aggregate Option Consideration which remain unpaid or unclaimed on the date which is six years from the Effective Date shall be forfeited to Subco and paid over to or as directed by Subco and the former Shareholders, Warrantholders and Optionholders shall thereafter have no right to receive their respective entitlement to the Aggregate Share Consideration, the Aggregate Option Consideration or the Aggregate Warrant Consideration, as applicable.

If the Company declares, sets aside or pays any dividend on, or makes any other actual, constructive or deemed distribution in respect of any of the Company Shares, or otherwise makes any payments to the Shareholders in their capacity as such, during the period commencing on the date of the Arrangement Agreement and ending on the Effective Date, Subco may reduce the amount of the Share Consideration by any amount it determines in its sole discretion, provided that such discount shall not exceed the amount of such dividend, distribution or payment received per Company Share. No dividend or other distribution declared or made after the Effective Time with respect to the Company Shares with a record date after the Effective Time shall be delivered to the holder of any unsurrendered certificate which, immediately prior to the Effective Time, represented outstanding Company Shares.

Any transfer of securities pursuant to this Plan of Arrangement shall be free and clear of any Liens.

From and after the Effective Time, until surrendered as contemplated by Sections 2.4(b) and 2.4(c):

In the event that any certificate which immediately prior to the Effective Time represented one or more outstanding Company Shares or Warrants shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed, the Depositary will pay such Person the cash that such Person would have been entitled to had such share or warrant certificate not been lost, stolen or destroyed. When authorizing such payment in exchange for any

lost, stolen or destroyed certificate, the Person to whom cash is to be paid shall, at the sole discretion of Subco, give a bond satisfactory to Subco in such sum as Subco may direct or otherwise indemnify the Depositary and Subco in a manner satisfactory to each of them against any claim that may be made against the Depositary or Subco with respect to the certificate alleged to have been lost, stolen or destroyed.

From and after the Effective Time (i) this Plan of Arrangement shall take precedence and priority over any and all Company Shares, Warrants and Options issued prior to the Effective Time, (ii) the rights and obligations of the registered holders of Company Shares, Warrants and Options, and the Company, Parent, Subco, the Depositary and any trustee or transfer agent therefor in relation thereto, shall be solely as provided for in this Plan of Arrangement, and (iii) all actions, causes of action, claims or proceedings (actual or contingent and whether or not previously asserted) based on or in any way relating to any Company Shares, Warrants or Options shall be deemed to have been settled, compromised, released and determined without liability except as set forth herein.

Notwithstanding that the transactions and events set out in this Plan of Arrangement shall occur and be deemed to have occurred in the order set out herein, without any further act or formality, each of the parties to the Arrangement Agreement shall make, do and execute, or cause to be made, done and executed, all such further acts, deeds, agreements, transfers, assurances, instruments or documents as may reasonably be required by any of them in order to implement this Plan of Arrangement and to further document or evidence any of the transactions or events set out herein.

The Company, Parent, Subco, one or more other subsidiaries of Parent or the Depositary, as the case may be, shall be entitled to directly or indirectly deduct and withhold from any amount otherwise payable pursuant to this Agreement or the Plan of Arrangement to any Shareholder, Optionholder or Warrantholder such amounts as are entitled or required to be deducted and withheld with respect to the making of such payment under the Tax Act or any other provision of domestic or foreign (whether national, federal, provincial, state, local or otherwise) Applicable Law relating to taxes. To the extent that amounts are so deducted and withheld and paid to the appropriate Governmental Entity directly or indirectly by the Company, Parent, Subco or one or more Subsidiaries of Parent or the Depositary, as the case may be, such deducted and withheld amounts shall be treated for all purposes of this Agreement and the Plan of Arrangement as having been paid to the Shareholders, Optionholders or Warrantholders, as the case may be, in respect of which such deduction and withholding was made by the Company, Parent, Subco, one or more Subsidiaries of the Parent or the Depository, as the case may be, provided that such withheld amounts are actually remitted to the appropriate Governmental Entity within the time required and in accordance with Tax Act or any other provision of domestic or foreign (whether national, federal, provincial, state, local or otherwise) Applicable Law relating to taxes.
