- 72 -

ADDITIONAL AGREEMENTS

7.1 Non-Solicitation

(1) Certicom shall not, directly or indirectly, through any officer, director, employee, representative (including any financial or other advisor) or agent of Certicom or any of its Subsidiaries, (i) make, solicit, initiate, assist, encourage or otherwise facilitate (including by way of furnishing information or entering into any form of agreement) the initiation of any inquiries or proposals regarding, constituting or that may reasonably be expected to lead to, an Acquisition Proposal, (ii) participate in any discussions or negotiations regarding, or provide any information with respect to, or otherwise co-operate in any way with, any effort or attempt by any other person to make or complete an Acquisition Proposal, (iii) withdraw or modify, or propose publicly to withdraw or modify, in a manner adverse to the Acquiror, the approval or recommendation of the Board or Special Committee of the Arrangement, (iv) approve, recommend or remain neutral with respect to, or propose publicly to approve, recommend or remain neutral with respect to, any Acquisition Proposal (it being understood that publicly taking no position or a neutral position with respect to an Acquisition Proposal until ten business days following the public announcement of such Acquisition Proposal shall not be considered a violation of this Section 7.1(1)) or (v) accept or enter into, or propose publicly to accept or enter into, any letter of intent, agreement in principle, agreement, arrangement or undertaking in respect of an Acquisition Proposal; provided that nothing contained in this Arrangement Agreement shall prevent the Board from considering, negotiating, accepting, approving, recommending to Certicom Shareholders or entering into an agreement in respect of a bona fide, written Acquisition Proposal received at any time prior to obtaining Shareholder Approval, in each case solely in the manner and under the circumstances set forth in this Section 7.1 or Section 7.2, as the case may be, and in each case where the Acquisition Proposal in question:

(a) did not result from a breach of any agreement between the person making such Acquisition Proposal and Certicom or any of its Subsidiaries, or this Section 7.1;

(b) is not subject to a due diligence condition;

- 74 -

(c) involves not less than 66 2/3% of the outstanding Certicom Shares or all or substantially all of the consolidated assets of Certicom; and

(d) in respect of which the Board determines in its good faith judgment, after consultation with its financial advisors and its outside counsel would, if consummated in accordance with its terms, result in a transaction that: (A) is reasonably capable of completion in accordance with its terms without undue delay, taking into account all legal, financial, regulatory and other aspects of such Acquisition Proposal and the person making such Acquisition Proposal; (B) is more favourable from a financial point of view to Certicom Shareholders than the Arrangement, and (C) is not subject to any financing condition and in respect of which any required financing to complete such Superior Proposal has been demonstrated to the satisfaction of the Board, acting in good faith (after receipt of advice from its financial advisors and outside legal counsel), will be obtained.

(any such Acquisition Proposal being referred to herein as a “Superior Proposal”).

(2) Certicom shall, and shall cause the officers, directors, employees, representatives and agents of Certicom and its Subsidiaries to, immediately terminate any existing discussions or negotiations with any parties (other than the Acquiror) with respect to any proposal that constitutes, or may reasonably be expected to constitute, an Acquisition Proposal. Certicom agrees not to release any third party from, and shall enforce, any confidentiality agreement relating to a potential Acquisition Proposal to which such third party is a party. Certicom further agrees not to release any third party from, and shall enforce, any standstill agreement or provision to which such third party is a party. Certicom shall immediately request the return or destruction of all information provided to any third party which, at any time since January 1, 2007, has entered into a confidentiality agreement with Certicom relating to a potential Acquisition Proposal to the extent that such information has not previously been returned or destroyed, and shall use all commercially reasonable efforts to ensure that such requests are honoured.

(3) Certicom shall immediately (and in any event within 24 hours of receipt by Certicom) notify the Acquiror of, at first orally and then in writing, of any Acquisition Proposal or inquiry that could lead to an Acquisition Proposal, in each case received after the date hereof of which any of its directors or officers become aware, or any amendments to the foregoing, or any request for non-public information relating to Certicom or any of its Subsidiaries in connection with an Acquisition Proposal or for access to the properties, books or records of Certicom or any of its Subsidiaries by any person that informs Certicom or such Subsidiary that it is considering making, or has made, an Acquisition Proposal and any amendment thereto and if in writing or electronic form, a copy thereof, and if not in writing or electronic form, a description of the material terms of any such Acquisition Proposal or inquiry, and shall provide the identity of the person making any such Acquisition Proposal or inquiry and such other details of the proposal or inquiry as the Acquiror may reasonably request. Certicom shall keep

- 75 -

the Acquiror fully informed of the status, including any change to the material terms, of any such Acquisition Proposal or inquiry, and shall provide to the Acquiror copies of all correspondence if in writing or electronic form, and if not in writing or electronic form, a description of the material terms of such correspondence sent to Certicom by or on behalf of any person making any such Acquisition Proposal.

(4) If, prior to the approval of the Arrangement Resolution by the Certicom Shareholders, Certicom receives a request for material non-public information from a person who proposes an unsolicited bona fide Acquisition Proposal that is subject to a due diligence condition or due diligence access condition, and the Board determines in good faith that such proposal would be, if consummated in accordance with its terms and the due diligence or due diligence access condition satisfied, a Superior Proposal, then, and only in such case, the Board may, subject to the execution by such person of a non-disclosure and standstill agreement having substantially the same terms as the Confidentiality Agreement (including, for greater certainty, a standstill provision substantially identical to that set forth in the Confidentiality Agreement), provide such person with access in accordance with subsection (1) to information regarding Certicom; provided, however that the person making the Acquisition Proposal shall not be precluded thereunder from making the Acquisition Proposal, and provided further that Certicom sends a copy of any such non-disclosure and standstill agreement to the Acquiror immediately upon its execution and the Acquiror is immediately provided with a list and copies of all information provided to such person not previously provided to the Acquiror and is immediately provided with access to information similar to that which was provided to such person.

(5) Certicom shall ensure that its officers and directors and those of its Subsidiaries and any financial or other advisors or representatives retained by it are aware of the provisions of this Section, and it shall be responsible for any breach of this Section by any such person or its advisors or representatives.

(6) Subject to the rights of the Acquiror in Sections 7.1, 7.2 and 8.2, nothing contained in this Arrangement Agreement shall prohibit the Board from making any disclosure to Certicom Shareholders or from calling and holding a meeting of Certicom Shareholders, or any of them, requisitioned by Certicom Shareholders, or any of them, in each case prior to the Effective Date if required under applicable Laws.

7.2 Right to Match

(1) Subject to Section 7.2(2), Certicom covenants that it will not accept, approve, recommend or enter into any agreement in respect of an Acquisition Proposal (other than a non-disclosure and standstill agreement permitted by Section 7.1(4)) nor withdraw, modify or qualify (or propose to withdraw, modify or qualify) in any manner adverse to Acquiror the approval or recommendation of the Arrangement, nor accept, approve or recommend any Acquisition Proposal unless:

(a) an Acquisition Proposal has been made that the Board determines in good faith constitutes a Superior Proposal;

- 76 -

(b) Certicom has complied with its obligations under Section 7.1 and the other provisions of this Article 7;

(c) Certicom has provided Acquiror with a notice in writing that there is a Superior Proposal together with all documentation comprising the Superior Proposal, including any value (including a range of value, if any) in financial terms that the Board has in consultation with its financial advisors determined should be ascribed to any non-cash consideration offered under the Superior Proposal;

(d) a period (the “Response Period”) of five Business Days shall have elapsed from the date on which the Acquiror received the entirety of the documentation set forth in the prior paragraph, and, if Acquiror has proposed to amend the terms of the Arrangement in accordance with Subsection 7.2(2), the Board shall have determined, in good faith, after consultation with its financial advisors and outside legal counsel, that the Acquisition Proposal is a Superior Proposal compared to the terms of the Arrangement after giving effect to any offer to amend the terms of the Arrangement made by the Acquiror in accordance with Section 7.2(2);

(e) Certicom terminates this Arrangement Agreement pursuant to Section 8.2(1)(e); and

(f) Certicom has previously, or concurrently will have, paid to the Acquiror the Termination Fee.

(2) During the Response Period, the Acquiror will have the right, but not the obligation, to offer to amend the terms of the Arrangement, and Certicom shall co-operate with the Acquiror with respect thereto, including negotiating in good faith with the Acquiror to enable the Acquiror to make such adjustments to the terms and conditions of this Arrangement Agreement and the Arrangement as the Acquiror deems appropriate and as would enable the Acquiror to proceed with the Arrangement and any related transactions on such adjusted terms. The Board will review in good faith any such offer by the Acquiror to amend the terms of the Arrangement, including an increase in, or modification of, the consideration to be received by the Certicom Shareholders, to determine whether the Acquisition Proposal to which the Acquiror is responding would be a Superior Proposal when assessed against the Arrangement as the Acquiror has offered to amend it. If the Board does not so determine, the Board will promptly reaffirm its recommendation of the Arrangement and enter into an amended Arrangement Agreement with Acquiror reflecting Acquiror’s offer to amend the terms of the Arrangement.

- 77 -

(3) If Certicom provides Acquiror with notice under Section 7.2(1) on a date that is less than five Business Days before the date of the Special Meeting, subject to applicable Laws, Certicom shall postpone or adjourn the Special Meeting to a date that is at least five Business Days but not more than 10 Business Days after the scheduled date of the Special Meeting.

(4) Each successive amendment 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 holders of Certicom Shares shall constitute a new Acquisition Proposal for the purposes of this Section 7.2 and the Acquiror shall be afforded a new Response Period in respect of each such Acquisition Proposal.

7.3 Agreement as to Damages

Notwithstanding any other provision relating to the payment of fees, including the payment of brokerage fees, if after the execution of this Arrangement Agreement the Arrangement is not consummated because:

(a) the Acquiror shall have terminated this Arrangement Agreement pursuant to Section 8.2(1)(d);

(b) (i) a bona fide Acquisition Proposal shall have been made or proposed to Certicom or to the Certicom Shareholders after the date hereof and prior to the Special Meeting; (ii) this Arrangement Agreement is terminated pursuant to Section 8.2(1)(a)(iii); and (iii) within 12 months of the date of this Arrangement Agreement an Acquisition Proposal is completed (whether or not such Acquisition Proposal is the same Acquisition Proposal referred to in clause (i) above);

(c) the Acquiror shall have terminated this Arrangement Agreement pursuant to Section 8.2(1)(b) in the event of any willful or intentional breach by Certicom of any of its obligations under this Arrangement Agreement; or

(d) Certicom shall have terminated this Arrangement Agreement pursuant to Section 8.2(1)(e),

then Certicom shall pay to the Acquiror, within two Business Days of the first to occur of (a), (b) or (c) above (or, in the case of (d) contemporaneously or prior to such termination), the amount of $4,000,000 (the “Termination Fee”) as liquidated damages in immediately available funds to an account designated by the Acquiror. For greater certainty, the Parties acknowledge that Certicom shall not be obligated to make more than one payment pursuant to this Section 7.3.

Each Party acknowledges that the payment amount set out in this Section 7.3 is a payment of liquidated damages which is a genuine pre-estimate of the damages which the Acquiror will suffer or incur as a result of the event giving rise to such damages and the resultant

- 78 -

termination of this Arrangement Agreement and is not a penalty. Certicom irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. For greater certainty, the Parties agree that, subject to Article 8, payment of the amount determined pursuant to this Section 7.3 in the manner provided in respect thereof is the sole monetary remedy of the Acquiror, provided however that payment by Certicom and acceptance by Acquiror of the amounts required to be paid pursuant to Section 7.3 shall not be in lieu of any damages or any other payment or remedy available in the event of any willful or intentional breach by Certicom of any of its obligations under this Arrangement Agreement.

7.4 Fees and Expenses

(1) Subject to subsections (2), (3) and (4), each Party shall pay all fees, costs and expenses incurred by such Party in connection with this Arrangement Agreement and the Arrangement.

(2) If this Arrangement Agreement is terminated by the Acquiror pursuant to (i) Section 8.2(1)(a)(iii) or (ii) Section 8.2(1)(b) based on any condition contained in Section 6.2(1) or (2) not having been satisfied or waived by the Acquiror at or before the Effective Date, then (unless the Acquiror shall have made a misrepresentation or breached a warranty or covenant under this Arrangement Agreement in such a manner that Certicom would be entitled to rely on the failure of a condition set forth in Section 6.3 as a reason not to complete the Arrangement and terminate this Arrangement Agreement pursuant to Section 8.2(1)(c)), Certicom shall pay the Acquiror $500,000 as reimbursement to the Acquiror for its out-of-pocket expenses incurred in connection with the transactions contemplated hereby.

(3) If this Arrangement Agreement is terminated by Certicom pursuant to Section 8.2(1)(c), then (unless Certicom shall have made a misrepresentation or breached a warranty or covenant under this Arrangement Agreement in such a manner that the Acquiror would be entitled to terminate this Arrangement Agreement pursuant to Section 8.2(1)(b)), the Acquiror shall pay Certicom $500,000 as reimbursement to Certicom for its out-of-pocket expenses incurred in connection with the transactions contemplated hereby.

(4) No fees shall be payable by Certicom under subsection (2) if Certicom has paid the amount provided under Section 7.3.

(5) The Acquiror shall be responsible for any filing fees made in support of any filings made to a Governmental Entity in respect of the transactions contemplated by this Arrangement Agreement.

(6) Payments of any amounts under subsection (2) (in the case only of terminations pursuant to Section 8.2(1)(b)), or subsection (3) shall not be exclusive of any other remedies to which the parties may be entitled as a result of the termination of this Arrangement Agreement.

- 79 -

7.5 Injunctive Relief

Nothing contained herein shall preclude a Party from seeking injunctive relief to restrain any breach or threatened breach of the covenants or agreements set forth in this Arrangement Agreement or the Confidentiality Agreement or otherwise to obtain specific performance of any of such acts, covenants or agreements, without the necessity of posting a bond or security in connection therewith.

7.6 Access to Information; Confidentiality

From the date hereof until the earlier of the Effective Time and the termination of this Arrangement Agreement, Certicom shall, and shall cause its Subsidiaries and their respective officers, directors, employees, independent auditors, accounting advisers and agents to, afford to the Acquiror and to the officers, employees, agents and representatives of the Acquiror such access as the Acquiror may reasonably require at all reasonable times, including for the purpose of facilitating integration business planning, to their officers, employees, agents, properties, books, records and Contracts, and shall furnish the Acquiror with all data and information as the Acquiror may reasonably request. The Parties acknowledge and agree that information furnished pursuant to this Section shall be subject to the terms and conditions of the Confidentiality Agreement.

7.7 Insurance and Indemnification

(1) The Acquiror shall, or in the alternative may request Certicom to, purchase “run-off” directors’ and officers’ liability insurance for a period of up to six years from the Effective Date, provided that the cost of such insurance shall not exceed $125,000.

(2) The Acquiror agrees that all rights to indemnification or exculpation now existing in favour of present and former officers and directors of Certicom and its Subsidiaries that are disclosed in Section 7.7 of the Disclosure Letter shall survive the completion of the Arrangement and shall continue in full force and effect for a period of not less than six years from the Effective Date.

7.8 Certain employee matters

Following the Effective Date, the Acquiror shall cause Certicom to make a bonus payment to all employees and consultants of Certicom as at the date of this Agreement in accordance with any Certicom’s annual incentive bonus plan and on a basis consistent with Certicom’s past practice following the completion of the fiscal year ending April 30, 2009; provided that any such employee or consultant whose position or engagement, as the case may be, is terminated prior to the payment of the time of payment of such bonuses shall receive at the time of payment of such bonuses an amount that would have been determined in accordance with the foregoing, pro-rated such that it is proportional to the duration of the portion of such fiscal year that the employee has been employed or engaged, as the case may be, without regard to any periods of notice that the individual may have at Law or pursuant to any Contract.

- 80 -

7.9 Termination of Certain Plans

Prior to the Closing Date, the Company shall take all actions necessary (including without limitation, the required corporate actions) to terminate, in accordance with all applicable Law, any and all tax qualified defined contribution plans sponsored or maintained by the Company that are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended, provided that the Acquiror shall use commercially reasonable efforts to offer those employees of the Company who will be employees of the Acquiror (including for greater certainty its direct and indirect subsidiaries) immediately following the Effective Time with the opportunity to participate in a tax-qualified defined contribution plan sponsored by the Acquiror (including, without limitation and subject to applicable Law, the ability of such employee to rollover any account balance and plan loan outstanding as of the Effective Time.

(5) each Share outstanding immediately prior to the Effective Time (including any Share issued upon the effective exercise of Options prior to the Effective Date), other than Shares held by the Acquiror and its affiliates, and other than Shares held (or previously held) by a Dissenting Shareholder, shall be transferred and deemed to be transferred by the holder thereof, without any further act or formality on its part, free and clear of all Liens, to the Acquiror in exchange for a payment in cash equal to the Cash Proceeds per Share, and the name of such holder will be removed from the register of holders of Shares and the Acquiror shall be recorded as the registered holder of Shares so transferred and shall be deemed to be the legal and beneficial owner thereof, free and clear of any Liens, and such payment shall be made upon the presentation and surrender by or on behalf of the holder to the Depository (acting on behalf of the Acquiror) of the certificate formerly representing Shares and a Letter of Transmittal as more fully described in Section 2.3.

2.3 Letter of Transmittal

At the time of mailing the Proxy Circular or as soon as practicable after the Effective Date, the Company shall forward to each Shareholder and Optionholder at the address of such holder as it appears on the register maintained by or on behalf of the Company in respect of the holders of Shares or Options, as the case may be, the Letter of Transmittal in the case of holders of Shares and instructions for obtaining delivery of that portion of the Purchase Price or the Option Consideration, as the case may be, payable to such holder following the Effective Date pursuant to this Plan of Arrangement.

2.4 Delivery of Purchase Price and Option Consideration

Prior to the Effective Date, (i) the Acquiror shall deposit, or arrange to be deposited, the money required for the payment of the aggregate Cash Proceeds per Share (the “Purchase Price”) for the Shares acquired pursuant to Section 2.2(5) for the benefit of and in trust for the holders of Shares entitled to receive Cash Proceeds per Share for each Share held by them in a special account with the Depository to be paid to or to the order of the respective former holders of such Shares without interest, and (ii) the Company shall deposit the money required for the payment of the aggregate Option Consideration for the Options which are acquired by the Company for cash pursuant to Section 2.2(3) for the benefit of and in trust for the holders of such Options in a special account with the Depository to be paid to or to the order of the respective former holders of such Options without interest. All such money shall be cash, denominated in Canadian dollars in same day funds payable at Xxxxxxx, Xxxxxxx. Such money shall not be used for any purpose except as provided in this Plan of Arrangement. Such payment to or to the order of the aforesaid former holders shall be made on presentation and surrender at the principal office of the Depository in the City of Toronto of, in the case of Shares, the certificate(s) representing the Shares which were acquired by the Acquiror pursuant to Section 2.2(5), and a duly completed Letter of Transmittal and such other documents and instruments, if any, as the Acquiror and/or the Depository may reasonably require. Upon surrender to the Depository for transfer to the Acquiror of, in the case of a Shareholder, a

C-6

certificate which immediately prior to the Effective Time represented Shares in respect of which the holder is entitled to receive cash under the Arrangement, and a duly completed Letter of Transmittal, and such other documents and instruments as would have been required to effect the transfer of the Shares formerly represented by such certificate under the CBCA and the by-laws of the Company and such additional documents and instruments as the Acquiror and the Depository may reasonably require, such former holder shall be entitled to receive in exchange therefor, and as soon as practicable after the Effective Time the Depository shall deliver to such holder, by cheque (or, if required by applicable laws, a wire transfer) for the amount of cash such holder is entitled to receive under the Arrangement (together, if applicable, with any unpaid dividends or distributions declared on the Shares, if any, prior to the Effective Time). In the event of a transfer of ownership of Shares that was not registered in the securities register of the Company, the amount of cash payable for such Shares under the Arrangement may be delivered to the transferee if the certificate representing such Shares is presented to the Depository as provided above, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable share transfer taxes have been paid. As soon as practicable after the Effective Time, the Depositary shall deliver on behalf of the Company to each Optionholder, as reflected on the books and records of the Company, a cheque (or, if required by applicable laws, a wire transfer) for the amount of cash such Optionholder is entitled to receive under the Arrangement in accordance with Section 2.2(3). Thereafter, the Acquiror and the Company shall be fully and completely discharged from their obligation to pay the Purchase Price to the former holders of such Shares and the aggregate Option Consideration to former holders of Options referred to in Section 2.2(5) and 2.2(3), respectively, and the rights of such holders shall be limited to receiving, without interest, from the Depository their proportionate part of the money so deposited on, in case of Shareholders, presentation and surrender of the documentation specified above. Any interest on such deposit shall belong to the Acquiror.

2.5 Expiration of Rights

Any amounts deposited with the Depository for the payment of the Purchase Price or the aggregate Option Consideration which remain unclaimed on the date which is six years from the Effective Date shall be forfeited to the Acquiror and paid over to or as directed by the Acquiror and the former holders of Shares and/or Options shall thereafter have no right to receive their respective entitlement to the Purchase Price or the aggregate Option Consideration, as applicable.

2.6 Dividends and Distributions

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 Shares, or otherwise makes any payments to the holders of the Shares in their capacity as such, during the period commencing on the date of the Arrangement Agreement and ending on the Effective Date, the Acquiror may reduce the amount of the Cash Proceeds per Share 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 Share. No dividend or other distribution declared or made after the Effective Time with respect to

C-7

the 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 Shares.

2.7 Transfers Free and Clear

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

(1) Each Shareholder may exercise rights of dissent with respect to its Shares pursuant to and in the manner set forth in section 190 of the CBCA as modified by the Interim Order and this Section 3.1 (the “Dissent Rights”); provided that a Notice of Dissent is received by the Company by no later than 5:00 p.m. (Toronto time) on the Business Day that is two Business Days prior to the date of the Special Meeting, or, if the Meeting is adjourned or postponed, 5:00 p.m. (Toronto time) on the Business Day that is two Business Days preceding the date of such adjourned or postponed Special Meeting.

(3) In addition to any other restrictions under Section 190 of the CBCA, none of the following shall be entitled to exercise Dissent Rights: (i) Optionholders and (ii) Shareholders who vote in favour of the Arrangement Resolution.

(4) In no case shall the Company, the Acquiror, the Depository, the registrar and transfer agent in respect of the Shares or any other Person be required to recognize a Dissenting Shareholder as a holder of Shares after the Effective Time and the name of each Dissenting Shareholder shall be deleted from the registers of holders of Shares as at the Effective Time as provided in Article 2.

C-8

ARTICLE 4

CERTIFICATES

4.1 Certificates

From and after the Effective Time, until surrendered as contemplated by Section 2.4, each certificate formerly representing Shares that, under the Arrangement, were transferred or deemed to be transferred to the Acquiror in return for cash pursuant to Section 2.2, shall represent and be deemed, at all times after the Effective Time, to represent only the right to receive upon such surrender the applicable amount per Share specified in Section 2.2(2) or Section 2.2(5) of this Plan of Arrangement. From and after the Effective Time, each Option referred to in Section 2.2(3) and any evidence thereof shall be deemed, at all times after the Effective Time, to represent only the right to receive the applicable Option Consideration specified in Section 2.2(3) of this Plan of Arrangement.

4.2 Lost Certificates

In the event that any certificate which immediately prior to the Effective Time represented one or more outstanding Shares that was sold and transferred to the Acquiror pursuant to Section 2.2 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 Depository will pay such Person the cash that such Person would have been entitled to had such share 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 the Acquiror, give a bond satisfactory to the Acquiror in such sum as the Acquiror may direct or otherwise indemnify the Depository and the Acquiror in a manner satisfactory to each of them against any claim that may be made against the Depository or the Acquiror with respect to the certificate alleged to have been lost, stolen or destroyed.

ARTICLE 5

C-9

5.2 Amendment

(1) Subject to the Sections 5.2(2), (4), (5) and (6), the Company and the Acquiror reserve the right to amend, modify and/or supplement this Plan of Arrangement at any time and from time to time prior to the Effective Date, provided that any such amendment, modification and/or supplement must be contained in a written document which is (i) agreed to in writing by the Company and the Acquiror, (ii) filed with the Court and, if made following the Special Meeting, approved by the Court subject to such conditions as the Court may impose, and (iii) if so required by the Court, communicated to Shareholders and/or Optionholders if and in the manner as required by the Court.

(2) Any amendment, modification or supplement to this Plan of Arrangement may be proposed by the Company or the Acquiror at any time prior to or at the Special Meeting (provided that the Company and the Acquiror shall have consented thereto in writing), with or without any prior notice or communication, and if so proposed and accepted by the Persons voting at the Special Meeting (other than as may be required under the Interim Order), shall become part of this Plan of Arrangement for all purposes.

(3) Any amendment, modification and/or supplement to this Plan of Arrangement that is approved by the Court following the Special Meeting shall be effective only if: (i) it is agreed to by each of the Company and the Acquiror; (ii) it is filed with the Court (other than amendments contemplated in Section 5.2(2) or (5), which shall not require such filing), and (iii) if required by the Court, it is consented to by holders of the Shares voting in the manner directed by the Court.

(4) Any amendment, modification and/or supplement to this Plan of Arrangement may be made by the Acquiror unilaterally after the Effective Date without the approval of the Shareholders or the Company provided that it concerns a matter which, in the reasonable opinion of the Acquiror, is of an administrative or ministerial nature required to better give effect to the implementation of this Plan of Arrangement and is not adverse to the financial or economic interests of the former Shareholders and Optionholders contemplated by this Plan of Arrangement prior to giving effect to such amendment, modification and/or supplement.

(5) Notwithstanding anything in this Plan of Arrangement or the Arrangement Agreement, the Acquiror shall be entitled, at any time prior to or following the Special Meeting, to modify this Plan of Arrangement to increase the consideration the Acquiror is prepared to make available to Shareholders or Optionholders pursuant to the Arrangement, whether or not the Board of the Company has changed its recommendation, provided that the Acquiror shall use its commercially reasonable efforts to provide not less than one Business Day’s prior written notice of such proposal to the Company.

C-10

(6) Notwithstanding anything in this Plan of Arrangement or the Arrangement Agreement, no amendment, revision, update or supplement shall be made to the Plan of Arrangement that (i) would require the Company to obtain any regulatory approval or the approval of Shareholders in respect of such amendment, revision, update or supplement other than at the Special Meeting, (ii) would prejudice the Company’s securityholders or would result in the withdrawal or material modification of the Fairness Opinion, (iii) would impede or materially delay the consummation of the transactions contemplated by the Plan of Arrangement, or (iv) would require the Company to take any action in contravention of applicable Law, the Charter Documents or any material provision of any material agreement to which it is a party.

5.3 Further Assurances

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.

5.4 Withholding Rights

Notwithstanding anything in the Arrangement Agreement or this Plan of Arrangement to the contrary, the Company, the Depository, the Acquiror or one or more Subsidiaries of the Acquiror, as the case may be, shall be entitled to deduct and withhold from any amount otherwise payable pursuant to this Plan of Arrangement to any holder of Shares or Options such amounts as are required to be deducted and withheld with respect to the making of such payment under the Income Tax Act (Canada), the United States Internal Revenue Code of 1986, or any provision of local, state, provincial or foreign tax Law, in each case, as amended, or the administrative practice of the relevant Governmental Entity administering such Law. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of the Arrangement Agreement and this Plan of Arrangement as having been paid to the former holder of the Shares or Options, as the case may be, in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority within the time required and in accordance with applicable Laws.
