Certificates representing Common Shares which are issued and Common Shares that are issued and registered in Book Entry Form, each after the Record Time but prior to the earlier of the Separation Time and the Expiration Time, shall also evidence, in addition to Common Shares, one Right for each Common Share represented thereby and shall have impressed on, printed on, written on or otherwise affixed to them a legend in a form substantially to the following effect (adapted accordingly as the Rights Agent may reasonably require):

Initial Exercise Price; Exercise of Rights; Detachment of Rights

Subject to adjustment as herein set forth, each Right will entitle the holder thereof, from and after the Separation Time and prior to the Expiration Time, to purchase one Common Share for the Exercise Price (and the Exercise Price and number of Common Shares are subject to adjustment as set forth below). Notwithstanding any other provision of this Agreement, any Rights held by the Corporation or any of its Subsidiaries shall be void.

Until the Separation Time:

the Rights shall not be exercisable and no Right may be exercised; and

each Right will be evidenced by the certificate for the associated Common Share of the Corporation registered in the name of the holder thereof (which certificate shall also be deemed to represent a Rights Certificate) or by Book Entry Form registration for the associated Common Share and will be transferable only together with, and will be transferred by a transfer of, such associated Common Share.

From and after the Separation Time and prior to the Expiration Time:

the Rights shall be exercisable; and

the registration and transfer of Rights shall be separate from and independent of Common Shares of the Corporation.

Promptly following the Separation Time, the Corporation will determine whether it wishes to issue Rights Certificates or whether it will maintain the Rights in Book Entry Form. In the event that the Corporation determines to maintain Rights in Book Entry Form, it will put in place such alternative procedures (as are determined necessary in consultation with the Rights Agent) for the Rights to be maintained in Book Entry Form (the “Book Entry Rights Exercise Procedures”), it being hereby acknowledged that such procedures shall, to the greatest extent possible, replicate in all substantive respects the procedures set out in this Agreement with respect to the exercise of the Rights Certificates and that the procedures set out in this Agreement shall be modified only to the extent necessary, as reasonably determined by the Rights Agent, to permit the Corporation to maintain the Rights in Book Entry Form. In such event, the Book Entry Rights Exercise Procedures shall be deemed to replace the procedures set out in the Agreement with respect to the exercise of Rights and all provisions of this Agreement referring to the Rights Certificates shall be applicable to Rights registered in Book Entry Form in like manner as the Rights in certificated form.

In the event the Corporation determines to issue Rights Certificates, it will prepare and the Rights Agent will mail to each holder of record of Common Shares as of the Separation Time (other than an Acquiring Person, any other person whose Rights are or become void pursuant to the provisions of Subsection 3.1(b) hereof and, in respect of any Rights Beneficially Owned by such Acquiring Person which are not held of record by such Acquiring Person, the holder of record of such Rights (a “Nominee”)) at such holder’s address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):

a Rights Certificate appropriately completed, representing the number of Rights held by such holder at the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the Corporation may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law, rule or regulation or with any rule or regulation of any self-regulatory organization, stock exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage; and

a disclosure statement prepared by the Corporation describing the Rights,

In the event that the Corporation determines to issue Rights Certificates, Rights may be exercised, in whole or in part, on any Business Day after the Separation Time and prior to the Expiration Time by submitting to the Rights Agent:

the Rights Certificate evidencing such Rights;

an election to exercise such Rights (an “Election to Exercise”) substantially in the form attached to the Rights Certificate appropriately completed and executed by the holder or his executors or administrators or other personal representatives or his or their legal attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Rights Agent; and

payment by certified cheque, banker’s draft or money order payable to the order of the Corporation, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover 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 exercised.

In the event that the Corporation determines to issue Rights Certificates, then upon receipt of a Rights Certificate, together with a completed Election to Exercise executed in accordance with Clause 2.2(f)(ii), which does not indicate that such Right is null and void as provided by Subsection 3.1(b), and payment as set forth in Clause 2.2(f)(iii), the Rights Agent (unless otherwise instructed by the Corporation in the event that the Corporation is of the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:

requisition from the transfer agent certificates representing the number of such 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 in accordance with Subsection 5.5(b);

after receipt of the certificates referred to in Clause 2.2(g)(i), deliver the same to or upon the order of the registered holder of such Rights Certificates, registered in such name or names as may be designated by such holder;

when appropriate, after receipt, deliver the cash referred to in Clause 2.2(g)(ii) to or to the order of the registered holder of such Rights Certificate; and

remit to the Corporation all payments received on exercise of the Rights.

In case the holder of any Rights shall exercise less than all the Rights evidenced by such holder’s Rights Certificate, a new Rights Certificate evidencing the Rights remaining unexercised (subject to the provisions of Subsection 5.5(a)) will be issued by the Rights Agent to such holder or to such holder’s duly authorized assigns.

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 as fully paid and non-assessable;

take all such action as may be necessary and within its power to comply with the requirements of the CBCA, the Securities Act and the securities laws or comparable legislation of each of the provinces of Canada, and 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 stock exchanges on which such Common Shares were traded immediately prior to the Stock Acquisition Date;

cause to be reserved and kept available out of the 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;

pay when due and payable, if applicable, any and all federal, provincial and municipal transfer taxes and charges (not including any income or capital taxes of the holder or exercising holder or any liability of the Corporation to withhold tax) which may be payable in respect of the original issuance or delivery of the Rights Certificates, or certificates for Common Shares to be issued upon exercise of any Rights, 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; and

after the Separation Time, except as permitted by Section 5.1, not take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

Adjustments to Exercise Price; Number of Rights

In the event the Corporation shall at any time after the date of this Agreement:

declare or pay a dividend on Common Shares payable in Common Shares (or other 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 or Dividend Reinvestment Plan;

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

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

issue any Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire Common Shares or other securities of the Corporation) in respect of, in lieu of or in exchange for existing Common Shares except as otherwise provided in this Section 2.3,

the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of Common Shares (or other capital stock) (the “Expansion Factor”) that a holder of one Common Share immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter as a result thereof; and

each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor,

In the event the Corporation shall at any time after the Record Time and prior to the Separation Time fix a record date for the issuance of rights, options or warrants to all holders of Common Shares 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 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 the Market Price per Common Share on such record date, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction:

the numerator of which shall be the number of Common Shares outstanding on such record date, plus the number of Common Shares that the aggregate offering 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 per Common Share; and

the denominator of which 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 the event the Corporation shall at any time after the Record Time and prior to the Separation Time fix a record date for the making of a distribution to all holders of Common Shares (including any such distribution made in connection with a merger, arrangement or amalgamation) of evidences of indebtedness, cash (other than a regular periodic cash dividend or a dividend referred to in Clause 2.3(a)(i), but including any dividend payable in other securities of the Corporation, other than Common Shares), assets or rights, options or warrants (excluding those referred to in Subsection 2.3(b)), the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction:

the numerator of which shall be the Market Price per Common Share on such record date, less the fair market value (as determined in good faith by the Board of Directors, 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), on a per share basis, of the portion of the cash, assets, evidences of indebtedness, rights, options or warrants so to be distributed; and

the denominator of which shall be such Market Price per Common Share.

Notwithstanding anything herein to the contrary, no adjustment in the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1.0% in the Exercise Price; provided, however, that any adjustments which by reason of this Subsection 2.3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth of a share. Notwithstanding the first sentence of this Subsection 2.3(d), any adjustment required by Section 2.3 shall be made no later than the earlier of:

three years from the date of the transaction which gives rise to such adjustment; or

the Expiration Time.

In the event the Corporation shall at any time after the Record Time and prior to the Separation Time issue any shares of capital stock (other than Common Shares), or rights, options or warrants to subscribe for or purchase any such capital stock, or securities convertible into or exchangeable for any such capital stock, in a transaction referred to in Clauses 2.3(a)(i) or (iv), if the Board of Directors acting in good faith determines that the adjustments contemplated by Clauses 2.3(a), (b) and (c) in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may determine what other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding Clauses 2.3(a), (b) and (c), such adjustments, rather than the adjustments contemplated by Clauses 2.3(a), (b) and (c), shall be made. The Corporation and the Rights Agent shall have authority to 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 Right originally issued by the Corporation subsequent to any adjustment made to the Exercise Price hereunder shall evidence the right to purchase, at the adjusted Exercise Price, the number of Common Shares purchasable from time to time hereunder upon exercise of a Right immediately prior to such issue, all subject to further adjustment as provided herein.

Irrespective of any adjustment or change in the Exercise Price or the number of Common Shares issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price per Common Share and the number of Common Shares which were expressed in the initial Rights Certificates issued hereunder.

In any case in which this Section 2.3 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Corporation may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Common Shares and other securities of the Corporation, if any, issuable upon such exercise over and above the number of Common Shares and other securities of the Corporation, if any, issuable upon such exercise on the basis

of the Exercise Price in effect prior to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder’s right to receive such additional shares (fractional or otherwise) or other securities upon the occurrence of the event requiring such adjustment.

Notwithstanding anything contained in this Section 2.3 to the contrary, the Corporation shall be entitled to make such reductions in the Exercise Price, in addition to those adjustments expressly required by this Section 2.3, as and to the extent that in their good faith judgment the Board of Directors determines to be advisable, in order that any:

consolidation or subdivision of Common Shares;

issuance (wholly or in part for cash) of Common Shares or securities that by their terms are convertible into or exchangeable for Common Shares;

stock dividends; or

issuance of rights, options or warrants referred to in this Section 2.3,

Whenever an adjustment to an Exercise Price or a change in the securities purchasable upon exercise of the Rights is made pursuant to this Section 2.3, the Corporation shall promptly:

file with the Rights Agent and with the transfer agent for the Corporation a certificate specifying the particulars of such adjustment or change; and

cause notice of the particulars of such adjustment or change to be given to the holders of the Rights.

Date on Which Exercise is Effective

Execution, Authentication, Delivery and Dating of Rights Certificates

The Rights Certificates shall be executed on behalf of the Corporation by its Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer, any Vice-President, Treasurer, Corporate Secretary, or any Assistant Secretary of the Corporation under the corporate seal of the Corporation reproduced thereon. The signature of any of these officers on the Rights Certificates may be manual, facsimile or email scanned copy. Rights Certificates bearing the manual, facsimile or email scanned 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 either before or after 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 a disclosure statement and Rights Certificates executed by the Corporation to the Rights Agent for countersignature, and the Rights Agent shall countersign (manually or by a facsimile or email scanned signature in a manner satisfactory to the Corporation) and send such disclosure statement and 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.

Registration, Transfer and Exchange

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 Corporation will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed registrar for the Rights (the “Rights Registrar”) for the purpose of maintaining the Rights Register for the Corporation and registering Rights and transfers of Rights as herein provided and the Rights Agent hereby accepts such appointment. 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.

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 satisfactory in form 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 and any other expenses (including the reasonable fees and expenses of the Rights Agent) connected therewith.

Mutilated, Destroyed, Lost and Stolen Rights Certificates

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:

evidence to their reasonable satisfaction of the destruction, loss or theft of any Rights Certificate; and

such security or indemnity as may be reasonably required by them in their sole discretion to save each of them and any of their agents harmless;

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 reasonable 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 the 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.

Persons Deemed Owners of Rights

Delivery and Cancellation of Certificates

Agreement of Rights Holders

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 certificate representing such Right;

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 or other securities 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 Voting Shares and upon the sole authority of the Board of Directors, acting in good faith, this Agreement may be supplemented or amended from time to time to cure any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with the intent of this Agreement or is otherwise defective, 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.

Rights Certificate Holder Not Deemed a Shareholder

Flip-in Event

Subject to Subsection 3.1(b) and Section 5.1, if prior to the Expiration Time a Flip-in Event occurs, each Right shall constitute, effective at the close of business on the eighth Trading Day after the Stock Acquisition Date, the right to purchase from the Corporation, upon exercise thereof in accordance with the terms hereof, that number of Common Shares 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 consummation or occurrence, an event of a type analogous to any of the events described in Section 2.3 shall have occurred).

Notwithstanding anything in this Agreement to the contrary, 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 of Rights, directly or indirectly, from 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), where such transferee becomes a transferee concurrently with or subsequent to the Acquiring Person becoming such in a transfer that the Board of Directors 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 concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person), that has the purpose or effect of avoiding Clause 3.1(b)(i),

From and after the Separation Time, the Corporation shall do all such acts and things as shall be necessary and within its power to ensure compliance with the provisions of this Section 3.1, including without limitation, all such acts and things as may be required to satisfy the requirements of the CBCA, the Securities Act and the securities laws or comparable legislation of each of the provinces of Canada and of the United States and each of the states thereof in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.

Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either Clause 3.1(b)(i) or (ii) 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:

General

The Corporation hereby appoints the Rights Agent to act as agent for the Corporation and the holders of the 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 (“Co-Rights Agents”) as it may deem necessary or desirable, subject to the approval of the Rights Agent. 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 the Co-Rights Agent. The Corporation agrees to pay all reasonable fees and expenses of the Rights Agent in respect of the performance of its duties under this Agreement. The Corporation also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, 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.

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, opinion, 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 and, at any time upon request, shall provide to the Rights Agent an incumbency certificate certifying the then current officers of the Corporation.

Merger, Amalgamation or Consolidation or Change of Name of Rights Agent

Any corporation into which the Rights Agent may be merged or amalgamated or with which it may be consolidated, or any corporation resulting from any merger, amalgamation, statutory arrangement or consolidation to which the Rights Agent is a party, or any corporation succeeding to the shareholder or stockholder services business of the 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. If 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, the successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and if at that time any of the Rights have not been countersigned, any successor Rights Agent may countersign such Rights Certificates 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.

If, at any time, the name of the Rights Agent is changed and at such time any of the Rights Certificates have been countersigned but not delivered, the Rights Agent may adopt the countersignature under its prior name and deliver Rights Certificates so countersigned; and if, at that time, any of the Rights Certificates have not 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.

Duties of Rights Agent

the Rights Agent, at the expense of the Corporation, may consult with and retain legal counsel (who may be legal counsel for the Corporation) and such other experts as it reasonably considers necessary to perform its duties hereunder, and the opinion of such counsel or other expert 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;

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 is specifically prescribed herein) is deemed to be conclusively proved and established by a certificate signed by a Person believed by the Rights Agent to be the Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer, any Vice-President, Treasurer, Corporate Secretary, or any Assistant Secretary 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 for its own negligence, bad faith or willful 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 have 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 certificate for a Common Share 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 exerciseability 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 is it deemed by any act hereunder 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 in writing with respect to the performance of its duties hereunder from any individual believed by the Rights Agent to be the Chairman of the Board, President, Chief Executive Officer, Chief Financial Officer, any Vice-President, Treasurer, Corporate Secretary or any Assistant Secretary of the Corporation, and to apply to such individuals 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 accordance with instructions of any such individual;

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 and nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity; and

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, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

Change of Rights Agent

Compliance with Money Laundering Legislation

that the Rights Agent’s written notice shall describe the circumstances of such non-compliance; and

that if such circumstances are rectified to the Rights Agent’s satisfaction within such 10-day period, then such resignation shall not be effective.

Redemption and Waiver

The Board of Directors acting in good faith may, until the occurrence of a Flip-in Event, upon prior written notice delivered to the Rights Agent, waive the

application of Section 3.1 to a particular Flip-in Event that would result from a Take-over Bid made by way of take-over bid circular to all holders of Voting Shares (which for greater certainty shall not include the circumstances described in Subsection 5.1(h)); provided that if the Board of Directors waives the application of Section 3.1 to a particular Flip-in Event pursuant to this Subsection 5.1(a), the Board of Directors 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 which is made by means of a take-over bid circular to all holders of Voting Shares prior to the expiry of any Take-over Bid (as the same may be extended from time to time) in respect of which a waiver is, or is deemed to have been, granted under this Subsection 5.1(a).

Subject to the prior consent of the holders of the Voting Shares or the Rights as set forth in Subsections 5.4(b) or (c), as applicable, the Board of Directors acting in good faith may, at its option, at any time prior to the provisions of Section 3.1 becoming applicable as a result of the occurrence of a Flip-in Event, elect to redeem all but not less than all of the 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 if 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”).

Where, pursuant to a Permitted Bid, a Competing Permitted Bid or an Exempt Acquisition under Subsection 5.1(a), a Person acquires outstanding Voting Shares, other than Voting Shares Beneficially Owned by such Person at the date of the Permitted Bid, the Competing Permitted Bid or the Exempt Acquisition under Subsection 5.1(a), then the Board of Directors shall immediately upon the consummation of such acquisition without further formality and without any approval under Subsection 5.4(b) or (c) be deemed to have elected to redeem the Rights at the Redemption Price.

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

If the Board of Directors is deemed under Subsection 5.1(c) to have elected, or elects under either of Subsection 5.1(b) or (d), to redeem the Rights, 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 shall be to receive the Redemption Price.

Within 10 days after the Board of Directors is deemed under Subsection 5.1(c) to have elected, or elects under Subsections 5.1(b) or (d), to redeem the Rights, the Corporation shall give notice of redemption to the holders of the then outstanding Rights by mailing such notice to each such holder at his last address as it appears upon the registry books of the Rights Agent or, prior to the Separation Time, on the registry books of the transfer agent for the Voting Shares. Any notice which is mailed in the manner provided herein shall be deemed given, whether or not the holder receives the notice. Each notice of redemption will state the method by which the payment of the Redemption Price will be made.

Upon the Rights being redeemed pursuant to Subsection 5.1(d), all the provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder of record of Common Shares as of the Separation Time had not been mailed to each such holder and for all purposes of this Agreement the Separation Time shall be deemed not to have occurred and the Rights shall remain attached to the outstanding Common Shares, subject to and in accordance with the provisions of this Agreement.

The Board of Directors may waive the application of Section 3.1 in respect of the occurrence of any Flip-in Event if the Board of Directors has determined within eight Trading Days following a Stock Acquisition Date that a Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person under this Agreement and, in the event that such a waiver is granted by the Board of Directors, such Stock Acquisition Date shall be deemed not to have occurred. Any such waiver pursuant to this Subsection 5.1(h) must be on the condition that such Person, within 14 days after the foregoing determination by the Board of Directors or such earlier or later date as the Board of Directors may determine (the “Disposition Date”), has reduced its Beneficial Ownership of Voting Shares so that the Person is no longer an Acquiring Person. If the Person remains an Acquiring Person at the close of business on the Disposition Date, the Disposition Date shall be deemed to be the date of occurrence of a further Stock Acquisition Date and Section 3.1 shall apply thereto.

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 of Directors under this Section 5.1.

Expiration

Issuance of New Rights Certificates

Supplements and Amendments

The Corporation may make amendments to this Agreement to correct any clerical or typographical error or, subject to Subsection 5.4(e), which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation, rules or regulations thereunder. 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 Voting Shares obtained as set forth below, at any time prior to the Separation Time, amend, vary or rescind 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 Voting 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, amend, vary 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 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 amendments made by the Corporation to this Agreement pursuant to Subsection 5.4(a) which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation, rule or regulation thereunder 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; or

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.

Fractional Rights and Fractional Shares

The Corporation shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights. After the Separation Time, in lieu of issuing fractional Rights, the Corporation shall pay to the holders of record of the Rights Certificates (provided the Rights represented by such Rights Certificates are not void pursuant to the provisions of Subsection 3.1(b), at the time such fractional Rights would otherwise be issuable), an amount in cash equal to the fraction of the Market Price of one whole Right that the fraction of a Right that would otherwise be issuable is of one whole Right.

The Corporation shall not be required to issue fractions of Common Shares upon exercise of Rights or to distribute certificates which evidence fractional Common Shares. In lieu of issuing fractional Common Shares, the Corporation shall pay to the registered holders of Rights Certificates, at the time such Rights are exercised as herein provided, an amount in cash equal to the fraction of the Market Price of one Common Share that the fraction of a Common Share that would otherwise be issuable upon the exercise of such Right is of one whole Common Share at the date of such exercise.

The Rights Agent shall have no obligation to make any payments in lieu of issuing fractions of Rights or Common Shares pursuant to Subsection 5.5(a) or 5.5(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.
