Upon receipt of a Rights Certificate, with a duly completed Election to Exercise (which does not indicate that the holder so exercising is an Acquiring Person) accompanied by payment as set forth in subsection 2.2(d) above, the Rights Agent will thereupon promptly:

requisition from the transfer agent or any co-transfer agent of the Common Shares certificates for the number of Common Shares to be purchased (the Corporation hereby irrevocably authorizing its transfer agent to comply with all such requisitions);

when appropriate, requisition from the Corporation the amount of cash to be paid in lieu of issuing fractional Common Shares and, after receipt, deliver such cash to or to the order of the registered holder of the Rights Certificate;

after receipt of the Common Share certificates, deliver the same to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder; and

The Corporation covenants and agrees that it will:

take all such action as may be necessary and within its power to ensure that all Common Shares delivered upon exercise of Rights shall, at the time of delivery of the certificates for such Common Shares (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered and fully paid and non-assessable;

take all such action as may be necessary and within its power to comply with any applicable requirements of the CBCA, the Securities Act, the securities acts or comparable legislation of each of the other provinces of Canada, the 1933 Securities Act and the 1934 Exchange Act, and the rules and regulations thereunder or any other applicable law, rule or regulation, in connection with the issuance and delivery of the Rights Certificates and the issuance of any Common Shares upon exercise of Rights;

use reasonable efforts to cause all Common Shares issued upon exercise of Rights to be listed on the principal exchanges or traded in the over-the-counter markets on which the Common Shares were traded immediately prior to the Stock Acquisition Date;

cause to be reserved and kept available out of its authorized and unissued Common Shares the number of Common Shares that, as provided in this Agreement, will from time to time be sufficient to permit the exercise in full of all outstanding Rights; and

pay when due and payable any and all Canadian and United States federal, provincial, and state transfer taxes (for greater certainty not including any income taxes or capital gains of the holder or exercising holder or any liability of the Corporation to withhold tax) and charges which may be payable in respect of the original issuance or delivery of

the Rights Certificates or certificates for Common Shares, provided that the Corporation shall not be required to pay any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being transferred or exercised.

In the event the Corporation shall at any time after the Effective Date and prior to the Expiration Time:

declare or pay a dividend on the Common Shares payable in Common Shares (or other securities or securities exchangeable for or convertible into or giving a right to acquire Common Shares or other securities of the Corporation) other than pursuant to any optional stock dividend program, dividend reinvestment plan or a dividend payable on Common Shares in lieu of a regular periodic cash dividend;

subdivide or change the then outstanding Common Shares into a greater number of Common Shares;

combine or change the then outstanding Common Shares into a smaller number of Common Shares; or

issue any Common Shares (or other capital stock or securities exchangeable for or convertible into or giving a right to acquire Common Shares or other capital stock) in respect of, in lieu of or in exchange for existing Common Shares in a reclassification, amalgamation, merger, statutory arrangement or consolidation,

In the event the Corporation shall at any time after the Effective Date and prior to the Expiration Time fix a record date for the making of a distribution to all holders of Common Shares of rights or warrants entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for or carrying a right to purchase or subscribe for Common Shares) at a price per Common Share (or, if a security convertible into or exchangeable for or carrying a right to purchase or subscribe for Common Shares, having a conversion, exchange or exercise price (including the price required to be paid to purchase such convertible or exchangeable security or right per share)) less than 90% of the Market Price per Common Share on such record date, the Exercise Price shall be adjusted in the manner set forth below. The Exercise Price in effect after such record date shall equal the Exercise Price in effect immediately prior to such record date multiplied by a fraction, of which the numerator shall be the number of Common Shares outstanding on such record date plus the number of Common Shares which the aggregate offer price of the total number of Common Shares so to be offered (and/or the aggregate initial conversion, exchange or exercise price of the convertible or exchangeable securities or rights so to be offered (including the price required to be paid to purchase such convertible or exchangeable securities or rights)) would purchase at such Market Price and of which the denominator shall be the number of Common Shares outstanding on such record date plus the number of additional Common Shares to be offered for subscription or purchase (or into which the convertible or exchangeable securities or rights so to be offered are initially convertible, exchangeable or exercisable). In case such subscription price is satisfied in whole or in part by consideration in a form other than cash the value of such consideration shall be as determined in good faith by the Board whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights.

In the event the Corporation shall at any time after the Effective Date and prior to the Expiration Time fix a record date for the making of a distribution to all holders of Common Shares of evidences of indebtedness or assets (other than a regular periodic cash dividend or a dividend paid in Common Shares) or rights or warrants entitling them to subscribe for or purchase Common Shares (or Convertible Securities in respect of Common Shares) at a price per Common Share (or, in the case of a Convertible Security in respect of Common Shares having a conversion or exercise price per share (including the price required to be paid to purchase such Convertible Security) less than 90% of the Market Price per Common Share on such record date (excluding those referred to in subsection 2.3(b)), the Exercise Price shall be adjusted in the manner set forth below. The Exercise Price in effect after such record date shall equal the Exercise Price in effect immediately prior to such record date less the fair market value (as determined in good faith by the Board) of the portion of the assets, evidences of indebtedness, rights or warrants so to be distributed applicable to each of the securities purchasable upon exercise of one Right (such determination to

be described in a statement filed with the Rights Agent shall be binding on the Rights Agent and the holders of the Rights). Such adjustment shall be made successively whenever such a record date is fixed.

Each adjustment made pursuant to this Section 2.3 shall be made as of:

the payment or effective date for the applicable dividend, subdivision, change, combination or issuance, in the case of an adjustment made pursuant to paragraph (a) above; and

the record date for the applicable dividend or distribution, in the case of an adjustment made pursuant to paragraph (b) or (c) above,

In the event the Corporation shall at any time after the Effective Date and prior to the Expiration Time issue any securities (other than Common Shares), or rights or warrants to subscribe for or purchase any such securities, or securities convertible into or exchangeable for any such securities, in a transaction referred to in clause (a)(i) or (a)(iv) above, or if the Corporation shall take any other action (other than the issue of Common Shares) which might have a negative effect on the holders of Rights, if the Board acting in good faith determines that the adjustments contemplated by paragraphs (a), (b) and (c) above are not applicable or will not appropriately protect the interests of the holders of Rights, the Corporation may determine what other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, if the adjustments contemplated by paragraphs (a), (b) and (c) above are applicable, notwithstanding such paragraphs, the adjustments so determined by the Corporation, rather than adjustments contemplated by paragraphs (a), (b) and (c) above, shall be made. The Corporation and the Rights Agent shall amend this Agreement in accordance with subsections 5.4(b) and 5.4(c), as the case may be, to provide for such adjustments.

Each adjustment to the Exercise Price made pursuant to this Section 2.3 shall be calculated to the nearest cent. Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation shall:

promptly prepare a certificate setting forth such adjustment and a brief statement of the facts accounting for such adjustment; and

promptly file with the Rights Agent and with each transfer agent for the Common Shares a copy of such certificate and mail a brief summary thereof to each holder of Rights who requests a copy.

Subject to Section 5.3, irrespective of any adjustment or change in the securities purchasable upon exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the securities so purchasable which were expressed in the initial Rights Certificates issued hereunder.

The Rights Certificates shall be executed on behalf of the Corporation by any one of a director, the Chief Executive Officer or the Chief Financial Officer of the Corporation. The signature of any of these officers on the Rights Certificates may be manual or facsimile. Rights Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Corporation shall bind the Corporation, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersignature and delivery of such Rights Certificates. Promptly after the Corporation learns of the Separation Time, the Corporation will notify the Rights Agent of such Separation Time and will deliver Rights Certificates executed by the Corporation to the Rights Agent for countersignature and disclosure statements describing the Rights, and the Rights Agent shall countersign (manually or by facsimile signature in a manner satisfactory to the Corporation) and mail such Rights Certificates to the holders of the Rights pursuant to subsection 2.2(c) hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent as aforesaid.

Each Rights Certificate shall be dated the date of countersignature thereof.

After the Separation Time, the Corporation will cause to be kept a register (the “Rights Register”) in which, subject to such reasonable regulations as it may prescribe, the Rights Agent will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed “Rights Registrar” for the purpose of maintaining the Rights Register for the Corporation and registering Rights and transfers of Rights as herein provided. In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times.

After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of subsection 2.6(d) below, the Corporation shall execute, and the Rights Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificates so surrendered.

All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid obligations of the Corporation, and such Rights shall be entitled to the same benefits under this Agreement as the Rights surrendered upon such registration of transfer or exchange.

Every Rights Certificate surrendered for registration of transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Corporation or the Rights Agent, as the case may be, duly executed by the holder thereof or such holder’s attorney duly authorized in writing. As a condition to the issuance of any new Rights Certificate under this Section 2.6, the Corporation may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto.

If any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the Corporation shall execute and the Rights Agent shall countersign and deliver in exchange therefor a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so surrendered.

If there shall be delivered to the Corporation and the Rights Agent prior to the Expiration Time (i) evidence of ownership of any Rights Certificate, (ii) evidence to their satisfaction of the destruction, loss or theft of any Rights Certificate and (iii) such security or indemnity as may be required by each of them in their sole discretion to save each of them and any of their agents harmless, then, in the absence of notice to the Corporation or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Corporation shall execute and upon its request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen.

As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Corporation may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Rights Agent) connected therewith.

Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence an original additional contractual obligation of the Corporation, whether or not the destroyed, lost or stolen Rights Certificate shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other Rights, duly issued hereunder.

to be bound by and subject to the provisions of this Agreement, as amended from time to time in accordance with the terms hereof, in respect of all Rights held;

that, prior to the Separation Time, each Right will be transferable only together with, and will be transferred by a transfer of, the associated Common Share;

that, after the Separation Time, the Rights Certificates will be transferable only on the Rights Register as provided herein;

that, prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) for registration of transfer, the Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on such Rights Certificate or the associated Common Share certificate made by anyone other than the Corporation or the Rights Agent) for all purposes whatsoever, and neither the Corporation nor the Rights Agent shall be affected by any notice to the contrary;

that such holder of Rights has waived his right to receive any fractional Rights or any fractional shares upon exercise of a Right (except as provided herein);

that, subject to the provisions of Section 5.4, without the approval of any holder of Rights or Common Shares and upon the sole authority of the Board acting in good faith this Agreement may be supplemented or amended from time to time as provided herein; and

that, notwithstanding anything in this Agreement to the contrary, neither the Corporation nor the Rights Agent shall have any liability to any holder of a Right or any other Person as a result of its inability to perform any of its obligations under this Agreement by reason of any preliminary or permanent injunction or other order, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation.

Subject to subsections 3.1(b), 5.1(b), 5.1(c) and 5.1(d) hereof, in the event that prior to the Expiration Time a Flip-in Event shall occur, the Corporation shall take such action as shall be necessary to ensure and provide that, within 10 Business Days thereafter or such longer period as may be required to satisfy the requirements of the applicable securities acts or comparable legislation, except as provided below, each Right shall thereafter constitute the right to purchase from the Corporation, upon exercise thereof in accordance with the terms hereof, that number of Common Shares of the Corporation having an aggregate Market Price on the date of consummation or occurrence of such Flip-in Event equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 in the event that after such date of consummation or occurrence an event of a type analogous to any of the events described in Section 2.3 shall have occurred with respect to such Common Shares).

Notwithstanding the foregoing or any other provisions of this Agreement, upon the occurrence of any Flip-in Event, any Rights that are or were Beneficially Owned on or after the earlier of the Separation Time or the Stock Acquisition Date by:

an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person); or

a transferee, direct or indirect, of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person) in a transfer made after the date hereof, whether or not for consideration, that the Board acting in good faith has determined is part of a plan, arrangement or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in connection with an Acquiring Person or any Affiliate or Associate of an Acquiring Person) that has the purpose or effect of avoiding clause (i) of this subsection 3.1(b):

Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either clause (i) or (ii) of subsection 3.1(b) or transferred to any nominee of any such Person, and any Rights Certificate issued upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall contain the following legend:

The Corporation hereby appoints the Rights Agent to act as agent for the Corporation and the holders of Rights in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Corporation may from time to time appoint such co-Rights Agents (the “Co-Rights Agents”) as it may deem necessary or desirable, subject to the consent of the Rights Agent, acting reasonably. In the event the Corporation appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as the Corporation may determine with the approval of the Rights Agent and Co-Rights Agent. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements reasonably incurred in the execution and administration of this Agreement and the exercise and performance of its duties hereunder (including the reasonable fees and disbursements of any expert retained by the Rights Agent with the approval of the Corporation, such approval not to be unreasonably withheld). The Corporation also agrees to fully indemnify the Rights Agent, its directors, officers, employees and agents for, and to hold them harmless against, any and all, direct or indirect loss, liability, cost, claim, action, damage, counsel fee, payment or expense, incurred without negligence, bad faith or wilful misconduct on the part of the Rights Agent or its directors, officers, employees and agents for anything done, suffered or omitted by the Rights Agent in connection with the acceptance, execution and

administration of this Agreement and the exercise and performance of its duties hereunder, including the costs and expenses of defending against any claim of liability, which right to indemnification will survive the termination of this Agreement or the resignation or removal of the Rights Agent. In no event will the Rights Agent be liable for special, indirect, consequential or punitive loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Rights Agent has been advised of the possibility of such damages. Any liability of the Rights Agent will be limited in the aggregate to an amount equal to the annual fee paid by the Corporation pursuant to this Agreement.

The Rights Agent shall be protected and shall incur no liability for or in respect of any action taken, suffered or omitted by it in connection with its administration of this Agreement in reliance upon any certificate for Common Shares, Rights Certificate, certificate for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper person or persons.

The Corporation shall inform the Rights Agent, in a reasonably timely manner, of events which may materially affect the administration of this Agreement by the Rights Agent. At any time, upon request, the Corporation shall provide to the Rights Agent an incumbency certificate with respect to the current directors and officers of the Corporation.

Any corporation into which the Rights Agent or any successor Rights Agent may be merged or amalgamated or with which it may be consolidated, or any corporation resulting from any merger, amalgamation or consolidation to which the Rights Agent or any successor Rights Agent is a party or any corporation succeeding to the shareholder, shareholder or stockholder services business of the Rights Agent or any successor Rights Agent, will be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 4.4 hereof. In case, at the time such successor Rights Agent succeeds to the agency created by this Agreement, any of the Rights Certificates have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates have not been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates will have the full force provided in the Rights Certificates and in this Agreement.

In case at any time the name of the Rights Agent is changed and at such time any of the Rights Certificates shall have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and in case at that time any of the Rights Certificates shall not have been countersigned, the Rights Agent may countersign such Rights Certificates either in its prior name or in its changed name; and in all such cases such Rights Certificates shall have the full force provided in the Rights Certificates and in this Agreement.

The Rights Agent may retain and consult with legal counsel (who may be legal counsel for the Corporation), and the opinion of such counsel will be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion; the Rights Agent may also, with the approval of the Corporation (such approval not to be unreasonably withheld) and at the expense of the Corporation, consult with such other experts as the Rights Agent shall consider necessary or appropriate to properly carry out the duties and obligations imposed under this Agreement and the Rights Agent shall be entitled to act and rely in good faith on the advice of any such expert.

Whenever in the performance of its duties under this Agreement the Rights Agent deems it necessary or desirable that any fact or matter be proved or established by the Corporation prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by a person believed by the Rights Agent to be a director, the Chief Executive Officer or the Chief Financial Officer of the Corporation and delivered to the Rights Agent; and such certificate will be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

The Rights Agent will be liable hereunder only for its own negligence, bad faith or wilful misconduct.

The Rights Agent will not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the certificates for Common Shares or the Rights Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and will be deemed to have been made by the Corporation only.

The Rights Agent will not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the due authorization, execution and delivery hereof by the Rights Agent) or in respect of the validity or execution of any Common Share certificate or Rights Certificate (except its countersignature thereof); nor will it be responsible for any breach by the Corporation of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible for any change in the exercisability of the Rights (including the Rights becoming void pursuant to subsection 3.1(b) hereof) or any adjustment required under the provisions of Section 2.3 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Section 2.3 describing any such adjustment); nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization of any Common Shares to be issued pursuant to this Agreement or any Rights or as to whether any Common Shares will, when issued, be duly and validly authorized, executed, issued and delivered and fully paid and non-assessable.

The Corporation agrees that it will perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Rights Agent for the carrying out or performing by the Rights Agent of the provisions of this Agreement.

The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any person believed by the Rights Agent to be a director, the Chief Executive Officer or the Chief Financial Officer of the Corporation, and to apply to such persons for advice or instructions in connection with its duties and it shall not be liable for any action taken or suffered by it in good faith in reliance upon instructions of any such person; it is understood that instructions to the Rights Agent shall, except where circumstances make it impracticable or the Rights Agent otherwise agrees, be given in writing and, where not in writing, such instructions shall be confirmed in writing as soon as reasonably possible after the giving of such instructions.

The Rights Agent and any shareholder or stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in Common Shares, Rights or other securities of the Corporation, or become pecuniarily interested in any transaction in which the Corporation may be interested, or contract with or lend money to the Corporation, or otherwise act as fully and freely as though it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity.

The Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent will not be answerable or accountable for any act, omission, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act, omission, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

The Board acting in good faith may, with the prior consent of holders of Common Shares or of the holders of Rights given in accordance with subsection 5.1(f) or 5.1(g), as the case may be, at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to the provisions of this Section 5.1, elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $0.000001 per Right appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 in the event that an event of the type analogous to any of the events described in Section 2.3 shall have occurred (such redemption price being herein referred to as the “Redemption Price”).

The Board acting in good faith may, with the prior consent of the holders of Common Shares given in accordance with subsection 5.1(f), determine, at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to this Section 5.1, if such Flip-in Event would occur by reason of an acquisition of Common Shares otherwise than pursuant to a Take-over Bid made by means of a Take-over Bid circular to all

holders of record of Common Shares and otherwise than in the circumstances set forth in subsection 5.1(d), to waive the application of Section 3.1 to such Flip-in Event. In the event that the Board proposes such a waiver, the Board shall extend the Separation Time to a date subsequent to and not more than 10 Business Days following the meeting of shareholders called to approve such waiver.

The Board acting in good faith may, prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived under this clause, determine, upon prior written notice to the Rights Agent, to waive the application of Section 3.1 to that Flip-in Event provided that the Flip-in Event would occur by reason of a Take-over Bid made by means of a Take-over Bid circular sent to all holders of record of Common Shares; further, provided that if the Board waives the application of Section 3.1 to such a Flip-in Event, the Board shall be deemed to have waived the application of Section 3.1 to any other Flip-in Event occurring by reason of any Take- over Bid made by means of a Take-over Bid circular to all holders of record of Common Shares which is made prior to the expiry of any Take-over Bid in respect of which a waiver is, or is deemed to have been, granted under this subsection 5.1(c).

The Board acting in good faith may, in respect of any Flip-in Event, waive the application of Section 3.1 to that Flip-in Event, provided that both of the following conditions are satisfied:

the Board has determined that the Acquiring Person became an Acquiring Person by inadvertence and without any intent or knowledge that it would become an Acquiring Person; and

such Acquiring Person has reduced its Beneficial Ownership of Common Shares such that at the time of waiver pursuant to this subsection 5.1(d) it is no longer an Acquiring Person.

Where, pursuant to a Permitted Bid, a Competing Permitted Bid or a Take-over Bid in respect of which the Board has waived, or is deemed to have waived, pursuant to subsection 5.1(c), the application of Section 3.1, a Person acquires outstanding Common Shares, then the Board shall immediately upon the consummation of such acquisition without further formality and without any approval under subsection 5.4(b) or 5.4(c) be deemed to have elected to redeem the Rights at the Redemption Price.

If a redemption of Rights pursuant to subsection 5.1(a) or a waiver of a Flip-in Event pursuant to subsection 5.1(b) is proposed at any time prior to the Separation Time, such redemption or waiver shall be submitted for approval to the holders of Common Shares. Such approval shall be deemed to have been given if the redemption or waiver is approved by the affirmative vote of a majority of the votes cast by Independent Shareholders represented in person or by proxy at a meeting of such holders duly held in accordance with applicable laws and the Corporation’s by-laws.

If a redemption of Rights pursuant to subsection 5.1(a) is proposed at any time after the Separation Time, such redemption shall be submitted for approval to the holders of Rights. Such approval shall be deemed to have been given if the redemption is approved by holders of Rights by a majority of the votes cast by the holders of Rights represented in person or by proxy at and entitled to vote at a meeting of such holders. For the purposes hereof, each outstanding Right (other than Rights which are Beneficially Owned by any Person referred to in clauses (i) to (v) inclusive of the definition of Independent Shareholders) shall be entitled to one vote, and the procedures for the calling, holding and conduct of the meeting shall be those, as nearly as may be, which are provided in the Corporation’s by-laws CBCA with respect to meetings of shareholders of the Corporation.

Where a Take-over Bid that is not a Permitted Bid is withdrawn or otherwise terminated after the Separation Time has occurred and prior to the occurrence of a Flip-in Event, the Board may elect to redeem all the outstanding Rights at the Redemption Price. Upon such redemption, all of the

provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and it shall be deemed not to have occurred and the Corporation shall be deemed to have issued replacement Rights to the holders of its then outstanding Common Shares, subject to and in accordance with the provisions of this Agreement.

If the Board elects or is deemed to have elected to redeem the Rights, and, in circumstances where subsection 5.1(a) is applicable, such redemption is approved by the holders of Common Shares or the holders of Rights in accordance with subsection 5.1(f) or (g), as the case may be, the right to exercise the Rights will thereupon, without further action and without notice, terminate and the only right thereafter of the holders of Rights will be to receive the Redemption Price.

Within 10 Business Days of the Board electing or having been deemed to have elected to redeem the Rights or, if subsection 5.1(a) is applicable within 10 Business Days after the holders of Common Shares or the holders of Rights have approved a redemption of Rights in accordance with subsection 5.1(f) or 5.1(g), as the case may be, the Corporation shall give notice of redemption to the holders of the then outstanding Rights by mailing such notice to each such holder at its last address as it appears upon the register of the Rights Agent or, prior to the Separation Time, on the register of the transfer agent for the Common Shares. Any notice which is mailed in the manner herein provided will be deemed given, whether or not the holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made. The Corporation may not redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this Section 5.1 or in connection with the purchase of Common Shares prior to the Separation Time.

The Corporation shall give prompt written notice to the Rights Agent of any waiver of the application of Section 3.1 made by the Board under this Section 5.1.

The Corporation may make amendments to this Agreement to correct any clerical or typographical error or which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation, rules or regulations thereunder. The Corporation may, prior to the date of the shareholders’ meeting referred to in Section 5.18, supplement, amend, vary, rescind or delete any of the provisions of this Agreement without the approval of any holders of Rights or Common Shares (provided that such action would not materially adversely affect the interests of the holders of Rights generally) where the Board acting in good ▇▇▇▇▇ ▇▇▇▇▇ such action necessary or desirable. Notwithstanding anything in this Section 5.4 to the contrary, no such supplement or amendment shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such supplement or amendment.

Subject to subsection 5.4(a), the Corporation may, with the prior consent of the holders of Common Shares, obtained as set forth below, at any time prior to the Separation Time, supplement, amend, vary, rescind or delete any of the provisions of this Agreement and the Rights

(whether or not such action would materially adversely affect the interests of the holders of Rights generally). Such consent shall be deemed to have been given if the action requiring such approval is authorized by the affirmative vote of a majority of the votes cast by Independent Shareholders present or represented at and entitled to be voted at a meeting of the holders of Common Shares duly called and held in compliance with applicable laws and the articles and by-laws of the Corporation.

The Corporation may, with the prior consent of the holders of Rights, at any time on or after the Separation Time, supplement, amend, vary, rescind or delete any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally), provided that no such amendment, variation or deletion shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent thereto. Such consent shall be deemed to have been given if such amendment, variation or deletion is authorized by the affirmative votes of the holders of Rights present or represented at and entitled to be voted at a meeting of the holders held in accordance with subsection 5.4(d) and representing 50% plus one of the votes cast in respect thereof.

Any approval of the holders of Rights shall be deemed to have been given if the action requiring such approval is authorized by the affirmative votes of the holders of Rights present or represented at and entitled to be voted at a meeting of the holders of Rights and representing a majority of the votes cast in respect thereof. For the purposes hereof, each outstanding Right (other than Rights which are void pursuant to the provisions hereof) shall be entitled to one vote, and the procedures for the calling, holding and conduct of the meeting shall be those, as nearly as may be, which are provided in the Corporation’s by-laws and the CBCA with respect to meetings of shareholders of the Corporation.

Any amendment made by the Corporation to this Agreement pursuant to subsection 5.4(a), other than any amendment to correct any clerical or typographical error, shall:

if made before the Separation Time, be submitted to the shareholders of the Corporation at the next meeting of shareholders and the shareholders may, by the majority referred to in subsection 5.4(b), confirm or reject such amendment; and

if made after the Separation Time, be submitted to the holders of Rights at a meeting to be called for on a date not later than immediately following the next meeting of shareholders of the Corporation and the holders of Rights may, by resolution passed by the majority referred to in subsection 5.4(d), confirm or reject such amendment.

The Corporation shall be required to provide the Rights Agent with notice in writing of any such amendment, rescission or variation to this Agreement as referred to in this Section 5.4 within five days of effecting such amendment, recission or variation.

Any supplement or amendment to this Agreement pursuant to subsection 5.4(b) through 5.4(e) shall be subject to the receipt of any requisite approval or consent from any governmental or regulatory authority having jurisdiction over the Corporation, including without limitation any requisite approval of stock exchanges on which the Common Shares are listed.

The Corporation shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights. After the Separation Time there shall be paid to the registered holders of the Rights Certificates, with regard to which fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the Market Price of a whole Right in lieu of such fractional Rights as of the date such fractional Rights would otherwise be issuable. The Rights Agent shall have no obligation to make any payments in lieu of fractional Rights unless the Corporation shall have provided the Rights Agent with the necessary funds to pay in full all amounts payable in accordance with subsection 2.2(e).

The Corporation shall not be required to issue fractional Common Shares upon exercise of the Rights or to distribute certificates which evidence fractional Common Shares. In lieu of issuing fractional Common Shares, the Corporation shall pay to the registered holder of Rights Certificates, at the time such Rights are exercised as herein provided, an amount in cash equal to the same fraction of the Market Price of one Common Share at the date of such exercise. The Rights Agent shall have no obligation to make any payments in lieu of fractional Common Shares unless the Corporation shall have provided the Rights Agent with the necessary funds to pay in full all amounts payable in accordance with subsection 2.2(e).

The Rights Agent shall have no obligation to make any payments in lieu of issuing fractions of Rights or Common Shares pursuant to paragraph (a) or (b), respectively, unless and until the Corporation shall have provided to the Rights Agent the amount of cash to be paid in lieu of issuing such fractional Rights or Common Shares, as the case may be.
