ARTICLE 2

RIGHTS

2.1 Legend on Share Certificates

Certificates for Common Shares issued after the Effective Time but prior to the earlier of the Separation Time and the Expiration Time, shall 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 substantially the following form:

“Until the Separation Time or the Expiration Time (as both terms are defined in the Shareholder Rights Plan Agreement referred to below), this certificate also evidences rights of the holder described in a Shareholder Rights Plan Agreement, dated June 30, 2023 (the “Shareholder Rights Plan Agreement”), between ATS Corporation (the “Corporation”) and Computershare Investor Services Inc. of Canada, as amended from time to time, the terms of which are incorporated herein by reference and a copy of which is on file at the principal executive offices of the Corporation. Under certain circumstances set out in the Shareholder Rights Plan Agreement, the rights may be amended, redeemed, may expire, may become null and void or may be evidenced by separate certificates and no longer evidenced by this certificate. The Corporation will mail or arrange for the mailing of a copy of the Shareholder Rights Plan Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.”

Any Common Shares issued and registered in Book Entry Form (that are evidenced by an advice or other statement on which are maintained electronically the records of the transfers) after the Effective Time but prior to the earlier of the Separation Time and the Expiration Time, shall evidence, in addition to the Common Shares, one Right for each Common Share represented by such registration and the registration record of such Common Shares shall include the foregoing legend, adapted accordingly as the Rights Agent may reasonably require.

Common Shares (both registered in Book Entry Form or for which share certificates have been issued) that are issued and outstanding at the Effective Time, which as at the Effective Time represented Common Shares, shall also evidence one Right for each Common Share evidenced thereby, notwithstanding the absence of the foregoing legend, until the earlier of the Separation Time and the Expiration Time.

2.2 Initial Exercise Price; Exercise of Rights; Detachment of Rights

(a) 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 (with the Exercise Price and number of Common Shares being 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.

- 18 -

(b) Until the Separation Time,

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

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

(c) From and after the Separation Time and prior to the Expiration Time:

(i) the Rights shall be exercisable; and

(ii) the registration and transfer of Rights shall be separate from and independent of Common Shares.

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 directed by 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 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 this Agreement with respect to the exercise of Rights and all provisions of this Agreement referring to Rights Certificates shall be applicable to Rights registered in Book Entry Form in like manner as to Rights in certificated form.

In the event that the Corporation determines to issue a Rights Certificate, it will prepare (or arrange to have prepared) and the Rights Agent will mail to each holder of record of Common Shares as of the Separation Time, and in respect of each Convertible Security converted into Common Shares after the Separation Time and prior to the Expiration Time promptly after such conversion, to the holder so converting (other than an Acquiring Person, any other Person whose Rights are or become void pursuant to the provisions of Section 3.1(b) 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):

- 19 -

(x) a Rights Certificate in substantially the form set out in Attachment 1 hereof, 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 judicial or administrative order 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

(y) a description of the Rights,

provided that a Nominee shall be sent the materials provided for in (x) and (y) in respect of all Common Shares held of record by it which are not Beneficially Owned by an Acquiring Person. In order for the Corporation to determine whether any Person is holding Common Shares which are Beneficially Owned by another Person the Corporation may require such first mentioned Person to furnish such information and documentation as the Corporation deems necessary or appropriate in order to make such determination.

(d) 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 in the manner specified in the Rights Certificate:

(i) the Rights Certificate evidencing such Rights;

(ii) an election to exercise such Rights (an “Election to Exercise”) substantially in the form attached to the Rights Certificate or in the form determined appropriate for Rights in Book Entry Form, in either case duly 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

(iii) payment by certified cheque, banker’s draft or money order payable to the order of the Rights Agent, 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 the transfer or delivery of Rights Certificates or the registration, in Book Entry Form, of the Common Shares in a name other than that of the holder of the Rights being exercised.

- 20 -

(e) In the event that the Corporation determines to issue a Rights Certificate, then upon receipt of a Rights Certificate, together with a completed Election to Exercise executed in accordance with Section 2.2(d)(ii), which does not indicate that such Right is null and void as provided by Section 3.1(b), and payment as set forth in Section 2.2(d)(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:

(i) direct the transfer agent to register, in the name of the holder of the Rights being exercised or in such other name as may be designated by such holder, in Book Entry Form the number of such Common Shares to be purchased (the Corporation hereby irrevocably authorizing its transfer agents to comply with all such requisitions);

(ii) when appropriate, requisition from the Corporation the amount of cash to be paid in lieu of issuing fractional Common Shares;

(iii) after receipt of confirmation from the transfer agent that the registration, in Book Entry Form, referred to in Section (i) has been completed, 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;

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

(v) tender to the Corporation all payments received on the exercise of the Rights.

(f) 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 Section 5.5(a)) will be issued by the Rights Agent to such holder or to such holder’s duly authorized assigns.

(g) The Corporation covenants and agrees that it will:

(i) take all such action as may be necessary and within its power to ensure that all Common Shares issued upon exercise of Rights shall, at the time of registration in Book Entry Form of such Common Shares (subject to payment of the Exercise Price), be duly authorized, validly issued and fully paid and non-assessable;

(ii) take all such action as may be necessary and within its power to comply with the provisions of Section 3.1 including all actions necessary to comply with the requirements of the OBCA, the Securities Act, the U.S. Securities Act, the U.S. Exchange 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;

- 21 -

(iii) use reasonable efforts to cause all Common Shares issued upon exercise of Rights to be listed on the principal stock exchanges on which such Common Shares were traded immediately prior to the Share Acquisition Date;

(iv) pay when due and payable, if applicable, 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, or the registration in Book Entry Form of 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 registration in Book Entry Form of Common Shares in a name other than that of the holder of the Rights being transferred or exercised; and

(v) 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.

2.3 Adjustments to Exercise Price; Number of Rights

The Exercise Price, the number and kind of securities subject to purchase upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 2.3.

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

(i) 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 Dividend Reinvestment Plan;

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

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

(iv) 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 and the number of Rights outstanding, or, if the payment or effective date therefor shall occur after the Separation Time, the securities

- 22 -

purchasable upon exercise of Rights, shall be adjusted as of the payment or effective date in the manner set forth below. If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1(a), the adjustment provided for in this Section 2.3 shall be in addition to, and shall be made prior to, any adjustment required under Section 3.1(a).

If the Exercise Price and number of Rights outstanding are to be adjusted:

(x) 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

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

and the adjusted number of Rights will be deemed to be distributed among the Common Shares with respect to which the original Rights were associated (if they remain outstanding) and the shares issued in respect of such dividend, subdivision, change, consolidation or issuance, so that each such Common Share (or other security of the Corporation) will have exactly one Right associated with it.

For greater clarity, if the securities purchasable upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right after such adjustment will be the securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter after giving full effect to such dividend, subdivision, change, consolidation or issuance.

If, after the Effective Time and prior to the Expiration Time, the Corporation shall issue any securities other than Common Shares in a transaction of a type described in Section 2.3(a)(i) or (iv), such securities shall be treated herein as nearly equivalent to Common Shares as may be practicable and appropriate under the circumstances and the Corporation and the Rights Agent agree to amend this Agreement in order to effect such treatment.

Adjustments pursuant to this Section 2.3(a) shall be made successively, whenever an event referred to in this Section 2.3(a) occurs.

In the event the Corporation shall at any time after the Effective Time and prior to the Separation Time issue any Common Shares otherwise than in a transaction referred to in this Section 2.3(a), each such Common Share so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such associated Common Share.

- 23 -

(b) In the event the Corporation shall at any time after the Effective 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 Convertible Securities in respect of Common Shares) at a price per Common Share (or, in the case of a Convertible Security, having a conversion, exchange or exercise price per security, including the price required to be paid to purchase such Convertible Security) 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:

(i) 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 Securities 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

(ii) 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 Securities so to be offered 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 statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights, options or warrants are not so issued, or if issued, are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted to the Exercise Price which would then be in effect if such record date had not been fixed, or to the Exercise Price which would be in effect based upon the number of Common Shares (or securities convertible into, or exchangeable or exercisable for Common Shares) actually issued upon the exercise of such rights, options or warrants, as the case may be.

For purposes of this Agreement, the granting of the right to purchase Common Shares (whether from treasury or otherwise) pursuant to a Dividend Reinvestment Plan or any employee benefit, stock option or similar plans shall be deemed not to constitute an issue of rights, options or warrants by the Corporation; provided, however, that, in all such cases, the right to purchase Common Shares is at a price per share of not less than 90% of the current market price per share (determined as provided in such plans) of the Common Shares.

- 24 -

(c) In the event the Corporation shall at any time after the Effective 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, 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 dividend referred to in Section 2.3(a)(i), but including any dividend payable in securities other than Common Shares), assets or rights, options or warrants (excluding those referred to in Section 2.3(b) hereof), 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:

(i) 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

(ii) 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 a 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.

(d) 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% 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 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 Section 2.3(d), any adjustment required by Section 2.3 shall be made no later than the earlier of:

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

(ii) the Expiration Time.

(e) In the event the Corporation shall at any time after the Effective Time and prior to the Separation Time issue any securities (other than Common Shares), or rights, options or warrants to subscribe for or purchase any such securities, or securities convertible into or exchangeable for any such securities in a transaction referred to in Sections 2.3(a)(i) or (iv) above, if the Board of Directors acting in good faith determines that the adjustments contemplated by Sections 2.3(a), (b) and (c) above

- 25 -

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 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, subject to the prior consent of the holders of the Common Shares or the Rights as set forth in Section 5.4(b) or (c), and the Corporation and the Rights Agent shall have authority upon receiving such prior consent of the holders of the Common Shares to amend this Agreement as appropriate to provide for such adjustments.

(f) 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.

(g) 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.

(h) 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.

(i) 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 shall determine to be advisable, in order that any:

(i) consolidation or subdivision of Common Shares;

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

(iii) dividends of securities; or

- 26 -

(iv) 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 or shall subject such shareholders to a lesser amount of tax.

(j) If, as a result of an adjustment made pursuant to Section 3.1, the holder of any Right thereafter exercised shall become entitled to receive any securities other than Common Shares, thereafter the number of such other securities so receivable upon exercise of any Right and the applicable Exercise Price thereof shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as may be practicable to the provisions with respect to the Common Shares contained in the foregoing subsections of this Section 2.3 and the provisions of this Agreement with respect to the Common Shares shall apply on like terms to any such other securities.

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

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

(ii) file with the Rights Agent and with each transfer agent for the Common Shares a copy of such certificate; and

(iii) mail a summary of the particulars of such adjustment or change to each holder of Rights who requests a copy.

Failure to file such certificate or to cause such notice to be given as aforesaid, or any defect therein, shall not affect the validity of any such adjustment or change.

2.4 Date on Which Exercise Is Effective

Each Person in whose name a registration in Book Entry Form for Common Shares or other securities, if applicable, is made upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Shares or other securities, if applicable, represented thereon, and such registration shall be dated the date upon which the Rights Certificate evidencing such Rights was duly surrendered in accordance with Section 2.2(d) (together with a duly completed Election to Exercise) and payment of the Exercise Price for such Rights (and any applicable transfer taxes and other governmental charges payable by the exercising holder hereunder) was made; provided, however, that if the date of such surrender and payment is a date upon which the Common Share transfer books of the Corporation are closed, such Person shall be deemed to have become the record holder of such shares on, and such certificate shall be dated, the next succeeding Business Day on which the Common Share transfer books of the Corporation are open.

- 27 -

2.5 Execution, Authentication, Delivery and Dating of Rights Certificates

Rights will be evidenced, in the case of Rights in Book Entry Form, by a statement issued under the Rights Agent’s direct registration system, or alternatively, if the Corporation determines to issue Rights Certificates, by the following procedures.

(a) The Rights Certificates shall be executed on behalf of the Corporation by any two directors or officers of the Corporation. The signature of any of these directors or officers on the Rights Certificates may be manual or mechanically or electronically reproduced. Rights Certificates bearing the manual or mechanically or electronically reproduced signatures of individuals who were at any time the proper officers or directors 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.

(b) Promptly after the Corporation learns of the Separation Time, the Corporation will notify the Rights Agent of such Separation Time and will deliver the Rights Certificates executed by the Corporation to the Rights Agent for countersignature, and the Rights Agent shall countersign (in a manner satisfactory to the Corporation) and send such Rights Certificates to the holders of the Rights pursuant to Section 2.2(c) hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent as aforesaid.

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

2.6 Registration, Transfer and Exchange

(a) 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 xxxxxx 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.

After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of Section 2.6(c), the Corporation will execute, and the Rights Agent will countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder’s instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificates so surrendered. Alternatively, in the case of the exercise of Rights in Book Entry Form, the Rights Agent shall provide the holder or the designated transferee or the transferees with one or more statements issued under the Rights Agent’s direct registration system evidencing the same aggregate number of Rights as did the direct registration system’s records for the Rights transferred or exchanged.

- 28 -

(b) 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.

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

(d) The Corporation shall not be required to register the transfer or exchange of any Rights after the Rights have been terminated pursuant to the provisions of this Agreement.

2.7 Mutilated, Destroyed, Lost and Stolen Rights Certificates

(a) 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.

(b) 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 security or indemnity as may be reasonably 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 the Corporation’s 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.

(c) 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.

- 29 -

(d) 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.

2.8 Persons Deemed Owners of Rights

The Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name a 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 for all purposes whatsoever. As used in this Agreement, unless the context otherwise requires, the term “holder” of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, of the associated Common Share).

2.9 Delivery and Cancellation of Certificates

All Rights Certificates surrendered upon exercise or for redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Rights Agent, be delivered to the Rights Agent and, in any case, shall be promptly cancelled by the Rights Agent. The Corporation may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Corporation may have acquired in any manner whatsoever, and all Rights Certificates so delivered shall be promptly cancelled by the Rights Agent. No Rights Certificate shall be countersigned in lieu of or in exchange for any Rights Certificates cancelled as provided in this Section 2.9, except as expressly permitted by this Agreement. The Rights Agent shall, subject to applicable laws, destroy all cancelled Rights Certificates and deliver a certificate of destruction to the Corporation.

2.10 Agreement of Rights Holders

Every holder of Rights, by accepting the same, consents and agrees with the Corporation and the Rights Agent and with every other holder of Rights:

(a) 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;

(b) 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;

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

- 30 -

(d) 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;

(e) 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);

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

(g) 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 to 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 government, 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.

2.11 Rights Certificate Holder Not Deemed a Shareholder

No holder, as such, of any Rights or Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose whatsoever the holder of any Common Share or any other share or security of the Corporation which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed or deemed or confer upon the holder of any Right or Rights Certificate, as such, any right, title, benefit or privilege of a holder of Common Shares or any other shares or securities of the Corporation or any right to vote at any meeting of shareholders of the Corporation whether for the election of directors or otherwise or upon any matter submitted to holders of Common Shares or any other shares of the Corporation at any meeting thereof, or to give or withhold consent to any action of the Corporation, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of the Corporation except as expressly provided herein, or to receive dividends, distributions or subscription rights, or otherwise, until the Right or Rights evidenced by Rights Certificates shall have been duly exercised in accordance with the terms and provisions hereof.

ARTICLE 3

ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN TRANSACTIONS

3.1 Flip-in Event

(a) Subject to Section 3.1(b) and Section 5.1, in the event that prior to the Expiration Time a Flip-in Event shall occur, then each Right shall constitute, effective at the close of business on the tenth Trading Day (or such longer period as may be required to satisfy the requirements of the Securities Act and any comparable legislation of any other applicable jurisdiction) after the Share Acquisition Date, the right to purchase from the Corporation, upon exercise of the Right in accordance with the terms of this Agreement, 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 the consummation or occurrence or event, an event of a type analogous to any of the events described in Section 2.3 shall have occurred).

(b) 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 Share Acquisition Date 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 an Acquiring Person); or

(ii) a transferee or other successor in title 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 or successor in title becomes a transferee or successor in title concurrently with or subsequent to the Acquiring Person becoming such in a transfer that the Board of Directors acting in good faith has determined is part of a plan, arrangement or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Associate or Affiliate of an Acquiring Person), that has the purpose or effect of avoiding Section 3.1(b)(i),

shall become null and void without any further action, and any holder of such Rights (including transferees) shall thereafter have no right to exercise such Rights under any provision of this Agreement and further shall thereafter not have any other rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise.

(c) Any Rights Certificate that would represent Rights Beneficially Owned by a Person described in either Section 3.1(b)(i) or 3.1(b)(ii) or transferred to any nominee of

- 32 -

any such Person, and any Rights Certificate that would be issued upon transfer, exchange, replacement or adjustment of any other Rights Certificate referred to in this sentence, shall either not be issued upon the instruction of the Corporation in writing to the Rights Agent or contain the following legend:

“The Rights represented by this Rights Certificate were issued to a Person who was an Acquiring Person or an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Shareholder Rights Plan Agreement) or a Person who was acting jointly or in concert with an Acquiring Person or an Affiliate or Associate of an Acquiring Person (as such terms are defined in the Shareholder Rights Plan Agreement). This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances specified in Section 3.1(b) of the Shareholder Rights Plan Agreement”;

provided, however, that the Rights Agent shall not be under any responsibility to ascertain the existence of facts that would require the imposition of such legend but shall impose such legend only if instructed to do so by the Corporation in writing or if a holder fails to certify upon transfer or exchange in the space provided on the Rights Certificate that such holder is not a Person described in such legend. The issuance of a Rights Certificate without the legend referred to in this Section 3.1(c) shall be of no effect on the provisions of Section 3.1(b).

Any Rights issued and registered in Book Entry Form (that are evidenced by an advice or other statement on which are maintained electronically the records of the transfers) after the Separation Time but prior to the Expiration Time, shall evidence one Right for each Right represented by such registration and the registration record of such Rights shall include the legend set forth in this Section 3.1(c), adapted accordingly as the Rights Agent may reasonably require.

ARTICLE 4

THE RIGHTS AGENT

4.1 General

(a) 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 of this Agreement, and the Rights Agent hereby accepts such appointment. The Corporation may from time to time appoint one or more co-Rights Agents (“Co-Rights Agents”) as it may deem necessary or desirable, subject to the approval of the Rights Agent, acting reasonably. In the event the Corporation appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as the Corporation may determine with the approval of the Rights Agent and the Co-Rights Agents. The Corporation agrees to pay the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and counsel fees and other disbursements reasonably incurred in the execution and administration of this Agreement and the exercise and performance

- 33 -

of its duties hereunder (including the reasonable fees and disbursements of any expert retained by the Rights Agent with the approval of the Corporation, acting reasonably). The Corporation also agrees to indemnify the Rights Agent, its officers, directors and employees for, and to hold them harmless against, any loss, liability, or expense, incurred without negligence, bad faith or wilful misconduct on the part of the Rights Agent, its officers, directors or employees for anything done or omitted by the Rights Agent, or such persons, in connection with the acceptance and administration of this Agreement, including legal costs and expenses, which right to indemnification will survive the termination of this Agreement and the resignation or removal of the Rights Agent.

(b) 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 certificate for Common Shares, Rights Certificate, certificate for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.

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

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

(a) 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 securityholder 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 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 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.

- 34 -

(b) 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.

4.3 Duties of Rights Agent

The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, all of which the Corporation and the holders of Common Shares and Rights, by their acceptance thereof, shall be bound.

(a) 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 by it in good faith and in accordance with such opinion and the Rights Agent may also, with the approval of the Corporation, acting reasonably, and at the expense of the Corporation, consult with such other experts as the Rights Agent shall consider necessary or appropriate to properly carry out the duties and obligations imposed under this Agreement and the Rights Agent shall be entitled to act and rely in good faith on the advice of any such expert.

(b) Whenever in the performance of its duties under this Agreement, the Rights Agent deems it necessary or desirable that any fact or matter be proved or established by the Corporation prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by two Persons believed by the Rights Agent to be directors or officers 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.

(c) 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.

(d) The Rights Agent will not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement (except as such are made or provided by the Rights Agent) 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.

- 35 -

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

(f) 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 by the Rights Agent for the carrying out or performing of the provisions of this Agreement.

(g) The Rights Agent is xxxxxx authorized and directed to accept instructions in writing (including by e-mail) with respect to the performance of its duties hereunder from any person believed by the Rights Agent to be a director or officer 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.

(h) 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 financially 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 the Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity, provided such actions would not place the Rights Agent in a position of conflict of interest with respect to its duties under this Agreement.

(i) 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.

- 36 -

(j) Notwithstanding any other provision of this Agreement, and whether such losses or damages are foreseeable or unforeseeable, the Rights Agent shall not be liable under any circumstances whatsoever for any (i) breach by any other party of securities law or other rule of any securities regulatory authority, (ii) lost profits or (iii) special, indirect, incidental, consequential, exemplary, aggravated or punitive losses or damages.

4.4 Change of Rights Agent

The Rights Agent may resign and be discharged from its duties under this Agreement upon 60 days’ notice (or such lesser notice as is acceptable to the Corporation) in writing mailed to the Corporation, to each transfer agent of Common Shares by registered or certified mail, and to the holders of the Rights in accordance with Section 5.9. The Corporation may remove the Rights Agent upon 30 days’ notice in writing, given to the Rights Agent and to each transfer agent of the Common Shares by personal delivery, or registered or certified mail. 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 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then by prior written notice to the Corporation the resigning or incapacitated Rights Agent (at the Corporation’s expense) or the holder of any Rights (which holder shall, with such notice, submit such holder’s Rights Certificate, if any, for inspection by the Corporation), may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. 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 authorized to carry on the business of a trust company in the Province of Ontario. After appointment, the successor Rights Agent will be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Corporation will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares, and mail a notice thereof in writing to the holders of the Rights in accordance with Section 5.9. Failure to give any notice provided for in this Section 4.4, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of any successor Rights Agent, as the case may be.

4.5 Compliance with Anti-Money Laundering Legislation

The Rights Agent shall retain the right not to act and shall not be liable for refusing to act if, due to a lack of information or for any other reason whatsoever, the Rights Agent reasonably determines that such an act might cause it to be in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline. Further, should the Rights Agent reasonably determine at any time that its acting under this Agreement has resulted in it being in non-compliance with any applicable anti-money laundering or anti-terrorist legislation, regulation or guideline, then it shall have the right to resign on 10 days’ prior written notice to the Corporation, provided: (i) that the Rights Agent’s written notice shall describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to the Rights Agent’s satisfaction within such 10 day period, then such resignation shall not be effective.

- 37 -

4.6 Privacy Legislation

The parties acknowledge that federal and/or provincial legislation that addresses the protection of individual’s personal information (collectively, “Privacy Laws”) applies to obligations and activities under this Agreement. Despite any other provision of this Agreement, neither party will take or direct any action that would contravene, or cause the other to contravene, applicable Privacy Laws. The Corporation will, prior to transferring or causing to be transferred personal information to the Rights Agent, obtain and retain required consents of the relevant individuals to the collection, use and disclosure of their personal information, or will have determined that such consents either have previously been given upon which the parties can rely or are not required under the Privacy Laws. The Rights Agent will use commercially reasonable efforts to ensure that its services hereunder comply with Privacy Laws.

MISCELLANEOUS

5.1 Redemption and Waiver

(a) The Board of Directors shall waive the application of Section 3.1 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(a) 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 Common 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 shall apply thereto.

(b) The Board of Directors acting in good faith may, prior to a Flip-in Event having occurred, upon prior written notice delivered to the Rights Agent, determine to waive the application of Section 3.1 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 holders of record of Common Shares (which for greater clarity shall not include the circumstances described in Section 5.1(a)), provided that if the Board of Directors waives the application of Section 3.1 to a particular Flip-in Event pursuant to this Section 5.1(b), 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

- 38 -

of Common 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 Section 5.1(b).

(c) In the event that prior to the occurrence of a Flip-in Event a Person acquires, pursuant to a Permitted Bid, a Competing Permitted Bid or an Exempt Acquisition under Section 5.1(b), outstanding Common Shares, then the Board of Directors shall, immediately upon the consummation of such acquisition without further formality be deemed to have elected to redeem the 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 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”).

(d) The Board of Directors may, with the prior approval of the holders of Common Shares or Rights given in accordance with the terms of Section 5.4, 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 the Redemption Price appropriately adjusted in a manner analogous to the applicable adjustments provided for in Section 2.3, which adjustments shall only be made in the event that an event of the type analogous to any of the events described in Section 2.3 shall have occurred.

(e) The Board of Directors may, with the prior approval of the holders of Common Shares given in accordance with Section 5.4 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 Common Shares or Convertible Securities otherwise than pursuant to a Take-over Bid made by means of a Take-over Bid circular to all registered holders of Common Shares and otherwise than in the circumstances set forth in Section 5.1(a), waive the application of Section 3.1 to such Flip-in Event. In such event, the Board of Directors shall extend the Separation Time to a date at least 10 Business Days subsequent to the meeting of shareholders called to approve such waiver.

(f) The Board of Directors may, prior to the close of business on the tenth Trading Day following a Share Acquisition Date or such later Business 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 to the related Flip-in Event, provided that the Acquiring Person has reduced its Beneficial Ownership of Common Shares (or has entered into a contractual arrangement with the Corporation, acceptable to the Board of Directors, to do so within 10 calendar days of the date on which such contractual arrangement is entered into or such other date as the Board of Directors may have determined) such that at the time the waiver becomes effective pursuant to this Section 5.1(f) 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.

- 39 -

(g) Where a Take-over Bid that is not a Permitted Bid or a Competing Permitted Bid is withdrawn or otherwise terminated after the Separation Time has occurred and prior to the occurrence of a Flip-in Event, the Board of Directors may elect to redeem all the outstanding Rights at the Redemption Price. Notwithstanding the foregoing, upon the Rights being redeemed pursuant to this Section 5.1(g), 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 this Agreement.

(h) If the Board of Directors is deemed under Section 5.1(c) to have elected or elects under Sections 5.1(d) or 5.1(g) 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.

(i) Within 10 Business Days after the Board of Directors is deemed under Section 5.1(c) to have elected or elects under Section 5.1(d) or 5.1(g) 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 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.

(j) The Corporation shall give prompt written notice to the Rights Agent of any waiver of the application of Section 3.1 pursuant to this Section 5.1.

5.2 Expiration

No Person shall have any rights pursuant to this Agreement or in respect of any Right after the Expiration Time, except the Rights Agent as specified in Section 4.1(a) of this Agreement.

5.3 Issuance of New Rights Certificates

Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Corporation may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change in the number or kind or class of securities purchasable upon exercise of Rights made in accordance with the provisions of this Agreement.

5.4 Supplements and Amendments

(a) The Corporation may make any amendments to this Agreement to correct any clerical or typographical error or which are required to maintain the validity of the Agreement as a result of any change in any applicable legislation, regulations or

- 40 -

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.

THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE CORPORATION, AND TERMINATION ON THE TERMS SET FORTH IN THE SHAREHOLDER RIGHTS PLAN AGREEMENT. UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SECTION 3.1(b) OF THE SHAREHOLDER RIGHTS PLAN AGREEMENT), RIGHTS BENEFICIALLY OWNED BY AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES, OR TRANSFEREES OF AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES, MAY BECOME VOID.

Until adjustment thereof in certain events provided in the Shareholder Rights Plan Agreement, the Exercise Price shall be: (i) until the Separation Time, an amount equal to three times the Market Price (as such term is defined in the Shareholder Rights Plan Agreement), from time to time, per Common Share; and (ii) from and after the Separation Time, an amount equal to three times the Market Price, as at the Separation Time, per Common Share.

This Rights Certificate is subject to all of the terms, provisions, and conditions of the Shareholder Rights Plan Agreement, which terms, provisions, and conditions are incorporated herein by reference and made a part hereof and to which Shareholder Rights Plan Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Rights Agent, the Corporation and the holders of the Rights Certificates. Copies of the Shareholder Rights Plan Agreement are on file at the registered office of the Corporation.

This Rights Certificate, with or without other Rights Certificates, upon surrender at any of the offices of the Rights Agent designated for such purpose, may be exchanged for another Rights Certificate or Rights Certificates of like tenor and date evidencing an aggregate number of Rights equal to the aggregate number of Rights evidenced by the Rights Certificate or Rights Certificates surrendered. If this Rights Certificate shall be exercised in part, the registered holder shall be entitled to receive, upon surrender hereof, another Rights Certificate or Rights Certificates for the number of whole Rights not exercised.

Subject to the Shareholder Rights Plan Agreement, the Rights evidenced by this Rights Certificate may be redeemed by the Corporation at the Redemption Price (as such term is defined in the Shareholder Rights Plan Agreement).

No fractional Common Shares will be issued upon the exercise of any Rights evidenced hereby.

No holder of this Rights Certificate, as such, shall be entitled to vote or receive dividends or be deemed for any purpose the holder of Common Shares or of any other securities which may at any time be issuable upon the exercise hereof, nor shall anything contained in the Shareholder Rights Plan Agreement or herein be construed to confer upon the holder hereof, as such, any of the Rights of a shareholder of the Corporation or any right to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to give or withhold consent to any corporate action, or to receive notice of meetings or other actions affecting shareholders (except as provided in the Shareholder Rights Plan Agreement), or to receive dividends or subscription rights, or otherwise, until the Rights evidenced by this Rights Certificate shall have been exercised as provided in the Shareholder Rights Plan Agreement.

This Rights Certificate shall not be valid or obligatory for any purpose until it shall have been countersigned by the Rights Agent.
