use reasonable efforts to cause, from and after such time as the Rights become exercisable, all Common Shares issued upon exercise of Rights to be listed upon issuance on each stock exchange on which the Common Shares were traded prior to the Separation Time;

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;

pay when due and payable any and all Canadian federal and provincial 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, 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 shares or other securities in a name other than that of the registered holder of the Rights being transferred or exercised; and

after the Separation Time, except as permitted by Section 5.1 or 5.4 hereof, 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.

Adjustment to Exercise Price upon changes to share capital. In the event the Corporation shall at any time after the Record Time:

declare or pay a dividend on the 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) other than the issue of Common Shares or such exchangeable or convertible securities to holders of Common Shares in lieu of but not in an amount which exceeds the value of regular periodic cash dividends;

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

Adjustment to Exercise Price upon issue of rights, options and warrants. In case the Corporation shall at any time after the Record 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 forty-five (45) calendar days after such record date) to subscribe for or purchase Common Shares (or shares having the same rights, privileges and preferences as Common Shares ("equivalent common shares")) or securities convertible into or exchangeable for or carrying a right to purchase Common Shares or equivalent common shares at a price per Common Share or per equivalent common share (or having a conversion price or exchange price or exercise price per share, if a security convertible into or exchangeable for or carrying a right to purchase Common Shares or equivalent common shares) less than ninety percent (90%) of 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 and/or equivalent 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 so to be offered) 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 and/or equivalent common shares to be offered for subscription or purchase (or into which the convertible or exchangeable securities are initially convertible, exchangeable or exercisable). In case such subscription price may be paid by delivery of consideration, part or all of which may be in a form other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors, whose determination shall be described in a certificate filed with the Rights Agent and 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 and, in the event that such rights or warrants are not so issued, the Exercise Price shall be adjusted to be the Exercise Price which would then be in effect if such record date had not been fixed.

Adjustment to Exercise Price upon Corporate Distributions. In case the Corporation shall at anytime after the Record Time fix a record date for a distribution to all holders of Common Shares (including any such distribution made in connection with a merger, amalgamation, arrangement, plan, compromise or reorganization in which the Corporation is the continuing or successor corporation) of evidences of indebtedness, cash (other than a regular periodic cash dividend or a regular periodic cash dividend paid in Common Shares, but including any dividend payable in securities other than Common Shares), assets or subscription rights, options or warrants (excluding those referred to in Section 2.3(b) above), 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) of the portion of the cash, assets or evidences of indebtedness so to be distributed or of such subscription rights, options or warrants applicable to a Common Share and the denominator of which shall be such Market Price per Common Share. Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such distribution is not so made, the Exercise Price shall be adjusted to be the Exercise Price which would have been in effect if such record date had not been fixed.

De minimis threshold for adjustment to Exercise Price. 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 one percent (1%) in the Exercise Price; provided, however, that any adjustments which by reason of this Section 2.3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 2.3 shall be made to the nearest cent or to the nearest one-hundredth of a Common Share or other share, as the case may be. Notwithstanding the first sentence of this Section 2.3(d), any adjustment required by this Section 2.3 shall be made no later than the earlier of (i) three (3) years from the date of the transaction which mandates such adjustment or (ii) the Expiration Time.

Corporation may provide for alternate means of adjustment. Subject to the prior consent of the holders of Voting Shares or Rights obtained as set forth in Section 5.4(2) or (3) hereof, as applicable, in the event the Corporation shall at any time after the Record Time issue any shares (other than Common Shares), or rights or warrants to subscribe for or purchase any shares, or securities convertible into or exchangeable for any such shares, in a transaction referred to in Section 2.3(a)(i) or (iv) or Section 2.3(b) or (c) above, if the Board of Directors acting in good faith determines that the adjustments contemplated by Sections

2.3(a), (b) and (c) above in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Corporation shall be entitled to determine what other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding Sections 2.3(a), (b) and (c) above, such adjustments, rather than the adjustments contemplated by Sections 2.3(a), (b) and (c) above, shall be made. The Corporation and the Rights Agent shall amend this Agreement as appropriate to provide for such adjustments.

Adjustment to Rights exercisable into shares other than Common Shares. If as a result of an adjustment made pursuant to Section 3.1 hereof, the holder of any Right thereafter exercised shall become entitled to receive any shares other than Common Shares, thereafter the number of such other shares so receivable upon exercise of any Right and the Exercise Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Shares contained in Sections 2.3(a), (b), (c), (d), (e), (g), (h), (i), (j), (k) and (l), above and below, as the case may be, and the provisions of this Agreement with respect to the Common Shares shall apply on like terms to any such other shares.

Rights to evidence right to purchase Common Shares at adjusted Exercise Price. 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 such Right, all subject to further adjustment as provided herein.

Adjustment to number of Common Shares purchasable upon adjustment to Exercise Price. Unless the Corporation shall have exercised its election as provided in Section 2.3(i) below, upon each adjustment of the Exercise Price as a result of the calculations made in Section 2.3(b) or (c) above, each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number of Common Shares (calculated to the nearest one ten-thousandth) obtained by (A) multiplying (x) the number of shares purchasable upon exercise of a Right immediately prior to this adjustment by (y) the Exercise Price in effect immediately prior to such adjustment of the Exercise Price, and (B) dividing the product so obtained by the Exercise Price in effect immediately after such adjustment of the Exercise Price.

Election to adjust number of Rights upon adjustment to Exercise Price. The Corporation shall be entitled to elect on or after the date of any adjustment of the Exercise Price to adjust the number of Rights, in lieu of any adjustment in the number of Common Shares purchasable upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of Common Shares for which a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such

Rights Certificates may contain Exercise Price before adjustment. 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 share and the number of shares which were expressed in the initial Rights Certificates issued hereunder.

Corporation may in certain cases defer issues of securities. 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 securities upon the occurrence of the event requiring such adjustment.

Corporation has discretion to reduce Exercise Price for tax reasons. Notwithstanding anything in 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 shall determine to be advisable in order that any (A) consolidation or subdivision of the Common Shares, (B) issuance of any Common Shares at less than the Market Price, (C) issuance of securities convertible into or exchangeable for Common Shares, (D) stock dividends or (E) issuance of rights, options or warrants, referred to in this Section 2.3 hereafter made by the Corporation to holders of its Common Shares, shall not be taxable to such shareholders.

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 the 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.

The Rights Certificates shall be executed on behalf of the Corporation by its Chairman, President, any of its Vice-Presidents or its Corporate Secretary. 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 a disclosure statement as described in Section 2.2(3), and the Rights Agent shall manually or by

facsimile signature countersign and send such Rights Certificates and disclosure statement to the holders of the Rights pursuant to Section 2.2(3) 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.

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 "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.

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 registered 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 or the Rights Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and the Corporation may require payment of a sum sufficient to cover any other expenses (including the fees and expenses of the Rights Agent) in connection therewith.

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 to their reasonable satisfaction of the destruction, loss or theft of any Rights Certificate, and (ii) such indemnity or other security as may be required by them 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 or the Rights Agent may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and the Corporation may require payment of a sum sufficient to cover any other expenses (including the fees and expenses of the Rights Agent) in connection 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 the holder thereof shall be entitled to all the benefits of this Agreement equally and proportionately with any and all other holders of Rights duly issued by the Corporation.

to be bound by and subject to the provisions of this Agreement, as amended, amended and restated, or supplemented 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 Share Registration (including the related Common Share certificate, if any) 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, or if no certificate evidences the Share Registration, satisfactory evidence of the associated Share Registration) for registration of transfer, the Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent shall be entitled to deem and treat the person in whose name the Rights Certificate is registered (or prior to the Separation Time, the associated Common Share certificate, or if no certificate evidences the Share Registration, the person in whose name the Share Registration is made) as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on such Rights Certificate or any 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 Rights;

that, in accordance with Section 5.4 hereof, without the approval of any holder of Rights and upon the sole authority of the Board of Directors acting in good faith this Agreement may be supplemented, amended or amended and restated from time to time pursuant to and 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 Section 3.1(2) below, and Sections 5.1(2), (3), (4) or (5) hereof, in the event that prior to the Expiration Time a Flip-in Event shall occur, the Corporation shall take such action as may be necessary to ensure and provide within ten (10) Trading Days of the Share Acquisition Date, or such longer period as may be required to satisfy all applicable requirements of the Securities Act, and the securities legislation of each other province of Canada that, 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 the 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 hereof in the event that after such date of occurrence an event of a type analogous to any of the events described in Section 2.3 hereof shall have occurred with respect to such Common Shares).

Notwithstanding anything in this Agreement to the contrary, upon the occurrence of any Flip-in Event, any Rights that are Beneficially Owned by (i) 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 such Acquiring Person, or any Affiliate or Associate of such Person so acting jointly or in concert, or (ii) a transferee or other successor in title of Rights, directly or indirectly, of an Acquiring Person (or of any Affiliate or Associate of an Acquiring Person) or of any Person acting

jointly or in concert with an Acquiring Person or any Associate or Affiliate of an Acquiring Person (or of any Affiliate or Associate of such Person so acting jointly or in concert) who becomes a transferee or successor in title concurrently with or subsequent to the Acquiring Person becoming such, shall become null and void without any further action, and any holder of such Rights (including transferees or successors in title) shall not have any rights whatsoever to exercise such Rights under any provision of this Agreement and shall not have thereafter any other rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise.

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

The Corporation hereby appoints the Rights Agent to act as agent for the Corporation 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 as it may deem necessary or desirable, subject to the prior approval of the Rights Agent, which shall not be unreasonably withheld. In the event the Corporation appoints one or more co-Rights Agents, the respective duties of the Rights Agents and co-Rights Agents shall be as the Corporation may determine, with the approval of the Rights Agent. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder or otherwise agreed to with the Corporation in writing and, from time to time, on demand of the Rights Agent, its reasonable expenses (including counsel fees and disbursements of legal counsel, to the extent they are reasonable) incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder. The Corporation also agrees to indemnify the Rights Agent, its officers, directors and employees for, and to hold such persons harmless against, any loss, liability, cost, claim, action, suit, damage, or expense incurred (that is not the result of gross negligence, bad faith or wilful misconduct on the part of any one or all of the Rights Agent, its officers, directors or employees) 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 from 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 Share Registration confirmed in writing by the transfer

agent of the Corporation, any certificate for Common Shares or any Rights Certificate or 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 reasonably 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.

In the event of any disagreement arising regarding the terms of this Agreement, the Rights Agent shall be entitled, at its option, to refuse to comply with any and all demands whatsoever until the dispute is settled either by written agreement amongst the parties to this Agreement or by a court of competent jurisdiction.

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, statutory arrangement or consolidation to which the Rights Agent or any successor Rights Agent is a party, or any corporation succeeding to the 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, in any event, shall be a reputable legal firm) 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 to be taken by it in good faith and in accordance with such opinion. Subject to the prior written consent of the Corporation, which consent shall not be unreasonably withheld, the Rights Agent may also consult with such other experts as the Rights Agent shall consider necessary or appropriate to properly carry out the duties and

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 proven and established by a certificate signed by a person reasonably believed by the Rights Agent to be the Chairman, President and Chief Executive Officer, Chief Financial Officer or General Counsel and Corporate 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 only for events which are the result of its own negligence, bad faith or wilful misconduct and that of its officers, directors and employees.

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, if any, 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, in its capacity as Rights Agent hereunder, 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 Section 3.1(2) 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 hereof 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 or fully paid and non-assessable.

Each of the Corporation and the Rights Agent 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 for the carrying out or performing 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 reasonably believed by the Rights Agent to be the Chairman, President and Chief Executive Officer, Chief Financial Officer, General Counsel and Corporate Secretary 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 accordance with 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 (including by e-mail) and, where not in writing, such instructions shall be confirmed in writing (including by e-mail) as soon as reasonably possible after the giving of such instructions.

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, with the prior written consent of the Corporation, by or through its attorneys or agents. 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 the prior written consent of the Corporation was obtained and reasonable care was exercised in the selection and continued employment thereof.

The Rights Agent may resign and be discharged from its duties under this Agreement upon at least sixty (60) days' notice (or such lesser notice as is acceptable to the Corporation) in writing mailed to the Corporation and to each transfer agent of Voting Shares by registered or certified mail, and to the holders of the Rights in accordance with Section 5.8 hereof (all of which shall be at the expense of the Corporation). The

Corporation may remove the Rights Agent upon thirty (30) days' notice in writing, mailed to the Rights Agent and to each transfer agent of the Voting Shares by registered or certified mail and to the holders of the Rights in accordance with Section 5.8 hereof.

If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Corporation will appoint a successor to the Rights Agent. If the Corporation fails to make such appointment within a period of sixty (60) days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the holder of any Rights (which holder shall, with such notice, submit such holder's Rights Certificate for inspection by the Corporation), then the Rights Agent or the holder of any Rights may apply to any court of competent jurisdiction for the appointment of a new Rights Agent at the Corporation's expense. Any successor Rights Agent, whether appointed by the Corporation or by such a court, shall be a corporation incorporated under the laws of Canada or a province thereof

Subject to the prior consent of the holders of Voting Shares or Rights obtained as set forth in Section 5.4(2) or Section 5.4(3) hereof, as applicable, the Board of Directors acting in good faith may, at any time prior to the occurrence of a Flip-in Event, elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $0.00001 per Right appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 hereof in the event that an event of the type described in Section 2.3 hereof shall have occurred (such redemption price being herein referred to as the "Redemption Price").

Subject to the prior consent of the holders of Voting Shares obtained as set forth in Section 5.4(2) hereof, the Board of Directors may, at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 hereof has not been waived pursuant to this Section 5.1, if such Flip-in Event would occur by reason of an acquisition of Voting Shares otherwise than pursuant to a Take-over Bid made by means of a Take-over Bid circular to all registered holders of Voting Shares and otherwise than in the circumstances set forth in Section 5.1(4) hereof, waive the application of Section 3.1 hereof to such Flip-in Event. In such event, the Board of Directors shall extend the Separation Time to a date at least ten (10) Business Days subsequent to the meeting of shareholders called to approve such waiver.

The Board of Directors acting in good faith, may, prior to the occurrence of a Flip-in Event, and upon prior written notice delivered to the Rights Agent, determine to waive the application of Section 3.1 hereof to a Flip-in Event that may occur by reason of a Take-over Bid made by means of a Take-over Bid circular to all registered holders of Voting Shares; provided that if the Board of Directors waives the application of Section 3.1 hereof to a particular Flip-in Event pursuant to this Section 5.1(3), the Board of Directors shall be deemed to have waived the application of Section 3.1 hereof 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 registered holders of Voting Shares prior to the expiry of any Take-over Bid in respect of which a waiver is, or is deemed to have been granted, pursuant to this Section 5.1(3).

The Board of Directors may, upon prior written notice delivered to the Rights Agent, waive the application of Section 3.1 hereof in respect of the occurrence of any Flip-in Event if the Board of Directors has determined, following a Share Acquisition Date and prior to the Separation Time, 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 Share Acquisition Date shall be deemed not to have occurred. Any such waiver pursuant to this Section 5.1(4) must be on the condition that such Person, within thirty (30) 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 such 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 Share Acquisition Date and Section 3.1 hereof shall apply thereto.

The Board of Directors may, prior to the close of business on the tenth (10^th) Trading Days following a Share Acquisition Date or such later Trading Day as they may from time to time determine, upon prior written notice delivered to the Rights Agent, waive the application of Section 3.1 hereof to the related Flip-in Event, provided that the Acquiring Person has reduced its Beneficial Ownership of Voting Shares (or has entered into a contractual arrangement with the Corporation or other undertaking, in a form acceptable to the Board of Directors, to do so within fifteen (15) days of the date on which such contractual arrangement or other undertaking is entered into or such earlier or later date as the Board of Directors may determine) such that at the time the waiver becomes effective pursuant to this Section 5.1(5) such Person is no longer an Acquiring Person. In the event of such a waiver becoming effective prior to the Separation Time, for the purposes of this Agreement, such Flip-in Event shall be deemed not to have occurred.

Where a Person acquires pursuant to a Permitted Bid, a Competing Bid or an Exempt Acquisition under Section 5.1(3) above, outstanding Voting Shares, then the Corporation shall immediately upon the consummation of such acquisition redeem the Rights at the Redemption Price.

If the Corporation is obligated under Section 5.1(6) above to redeem the Rights, or if the Board of Directors elects under Section 5.1(1) above or Section 5.1(9) below to redeem the Rights, the right to exercise the Rights will thereupon, without further action and without notice, terminate and each Right will after redemption be null and void and the only right thereafter of the holders of Rights shall be to receive the Redemption Price.

Within ten (10) days after the Corporation is obligated under Section 5.1(6) above to redeem the Rights, or the Board of Directors elects under Section 5.1(1) above or Section 5.1(9) below to redeem the Rights, the Corporation shall give notice of redemption to the

holders of the then outstanding Rights by mailing such notice to all such holders at their last address as they appear upon the Rights Register or, prior to the Separation Time, on the registry books of the transfer agent for the Common Shares. Any notice which is mailed in the manner herein provided shall 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 and other than in connection with the purchase of Common Shares prior to the Separation Time.

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.

Notwithstanding the Rights being redeemed pursuant to Section 5.1(9) above, 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 outstanding Common Shares, subject to and in accordance with the provisions of this Agreement.

The Corporation may, prior to any shareholders’ meeting called to approve this Agreement, supplement, amend or amend and restate this Agreement without the approval of any holder of Rights or Voting Shares. Thereafter, the Corporation may from time to time supplement, amend or amend and restate this Agreement without the approval of any holders of Rights or Voting Shares to correct any clerical or typographical error or to maintain the validity of the Agreement as a result of a change in or in the interpretation of any applicable legislation or regulations or rules thereunder.

Notwithstanding anything in this Section 5.4 to the contrary, no supplement, amendment, or amendments and restatements shall be made to the provisions of Article 4 hereof except with the written concurrence of the Rights Agent to such supplement, amendment, or amendments and restatements.

Subject to Section 5.4(1) above, the Corporation may, with the prior consent of the holders of the 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 provided by the holders of Voting Shares at a meeting of the holders of Voting Shares, which meeting shall be called and held in compliance with applicable laws and regulatory requirements and the requirements in the articles and by-laws of the Corporation. Subject to compliance with any requirements imposed by the foregoing, consent shall be deemed to have been given if the proposed amendment, variation or revision is approved by the affirmative vote of a majority of the votes cast by all holders of Voting Shares, voting together as a single class (other than any holder of Voting Shares who is an Offeror pursuant to a Take-over Bid that is not a Permitted Bid or Competing Bid with respect to all Voting Shares Beneficially Owned by such Person), represented in person or by proxy at the meeting.

The Corporation may, with the prior consent of the holders of Rights, at any time after the Separation Time and before the Expiration 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).

Any consent or 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 articles and the BCBCA with respect to a meeting of shareholders of the Corporation.

The Corporation shall be required to provide the Rights Agent with notice in writing of any such amendment, variation or deletion to this Agreement as referred to in this Section 5.4 within 5 days of effecting such amendment, variation or deletion.

Any supplements, amendments, or amendments and restatements made by the Corporation to this Agreement pursuant to Section 5.4(1) above which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation or regulations or rules 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 Section 5.4(2) above 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 Section 5.4(4) above, confirm or reject such amendment.

The Corporation shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights. Any such fractional Right shall be null and void and the Corporation will not have any obligation or liability in respect thereof.

The Corporation shall not be required to issue fractions of Common Shares or other securities upon exercise of the Rights or to distribute certificates which evidence fractional Common Shares or other securities. In lieu of issuing fractional Common Shares or other securities, 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 same fraction of the Market Price of one Common Share. 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 Section 2.2(5).

Notices or demands authorized or required by this Agreement to be given or made by the Rights Agent or by the holder of any Rights to or on the Corporation shall be sufficiently given or made if delivered or sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Rights Agent) as follows:

Any notice or demand authorized or required by this Agreement to be given or made by the Corporation or by the holder of any Rights to or on the Rights Agent shall be sufficiently given or made if delivered or sent by first-class mail, postage prepaid, addressed (until another address is filed in writing with the Corporation) as follows:

Notices or demands authorized or required by this Agreement to be given or made by the Corporation or the Rights Agent to or on the holder of any Rights shall be sufficiently given or made if delivered or sent by first-class mail, postage prepaid, addressed to such holder at the address of such holder as it appears upon the Rights Register or, prior to the Separation Time, on the registry books of the transfer agent for the Common Shares. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the holder receives the notice.

If in the opinion of the Board of Directors (who may rely upon the advice of counsel) any action or event contemplated by this Agreement would require compliance with the securities laws or comparable legislation of a jurisdiction outside Canada and the United States, the Board of Directors acting in good faith may take such actions as it may deem appropriate to ensure such compliance. In no event shall the Corporation or the Rights

Agent be required to issue or deliver Rights or securities issuable on exercise of Rights to Persons who are citizens, residents or nationals of any jurisdiction, other than Canada or the United States, in which such issue or delivery would be unlawful without registration of the relevant Persons or securities for such purposes, or (until such notice is given as required by law) without advance notice to any regulatory or self-regulatory body.

The Corporation shall use its best efforts to (i) file, as soon as practicable following the Separation Time, a registration statement under the 1933 Act, with respect to the securities purchasable upon exercise of the Rights on an appropriate form, (ii) cause such registration statement to become effective as soon as practicable after such filing, and (iii) cause such registration statement to remain effective (with a prospectus at all times meeting the requirements of the 1933 Act) until the earlier of (A) the date as of which the Rights are no longer exercisable for such securities, and (B) the Expiration Time. The Corporation will also take such action as may be appropriate under, or to ensure compliance with, the securities or "blue sky" laws of the various states in connection with the exercisability of the Rights. The Corporation may temporarily suspend, for a period of time not to exceed ninety (90) days after the date set forth in clause (i) of the first sentence of this Section 5.17(2), the exercisability of the Rights in order to prepare and file such registration statement and permit it to become effective. Upon any such suspension, the Corporation shall issue a public announcement stating that the exercisability of the Rights has been temporarily suspended, as well as a public announcement at such time as the suspension has been rescinded.
