WHEREAS:

The Board of Directors has determined that it is advisable to adopt a shareholder rights plan (the “Rights Plan”) to ensure, to the extent possible, that all shareholders of the Corporation are treated fairly in connection with any takeover offer for the Corporation or other acquisition of control of the Corporation.

In order to implement the Rights Plan, the Board of Directors has:

(b)

authorized the issuance of one Right in respect of each Common Share issued after the Record Time and prior to the earlier of the Separation Time and the Expiration Time; and

(c)

authorized the issuance of Rights Certificates to holders of Rights pursuant to the terms and subject to the conditions set forth herein.

Each Right entitles the holder thereof, after the Separation Time, to purchase securities of the Corporation pursuant to the terms and subject to the conditions set forth herein.

The Corporation desires to appoint the Rights Agent to act on behalf of the Corporation, and the Rights Agent is willing to so act, in connection with the issuance, transfer, exchange and replacement of Rights Certificates, the exercise of Rights and other matters referred to herein.

ARTICLE 2 - THE RIGHTS

2.1

Legend on Common Share Certificates

Certificates representing Common Shares issued after the Record 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 thereby and shall have impressed on, printed on, written on or otherwise affixed to them the following legend:

“Until the Separation Time (as defined in the Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain Rights as set forth in a Shareholder Rights Plan Agreement, dated as of April 20, 2006 (the “Rights Agreement”), between Metallica Resources Inc. (the “Corporation”) and Equity Transfer Services Inc., as Rights Agent, the terms of which are hereby incorporated herein by reference and a copy of which is on file at the registered office of the Corporation. Under certain circumstances, as set forth in the Rights Agreement, such Rights may be amended or redeemed, may expire, may become void (if, in certain cases, they are “Beneficially Owned” by an “Acquiring Person”, as such terms are defined in the Rights Agreement, or a transferee thereof) or may be evidenced by separate certificates and may no longer be evidenced by this certificate. The Corporation will mail or arrange for the mailing of a copy of the Rights Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.”

Certificates representing Common Shares that are issued and outstanding at the Record Time shall 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, including without limitation as set forth in Article 3, 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 as at the Business Day immediately preceding Separation Time (which Exercise Price and number of Common Shares are subject to adjustment as set forth below). Notwithstanding any other provision of this Agreement, any Rights held by the Corporation or any of its Subsidiaries shall be void.

(b)

Until the Separation Time, (i) the Rights shall not be exercisable and no Right may be exercised; and (ii) for administrative purposes, each Right will be evidenced by the certificate for the associated Common Share registered in the name of the holder thereof (which certificate shall be deemed to represent a Rights Certificate) 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, the Rights may be exercised, and the registration and transfer of the Rights shall be separate from and independent of Common Shares. Promptly following the Separation Time, the Corporation will prepare or cause to be 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, the Corporation will prepare or cause to be prepared and the Rights Agent will mail to the holder so converting (other than an Acquiring Person 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 record to the Rights Agent for this purpose):

(i)

a Rights Certificate in substantially the form of Exhibit A hereto 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 article or regulation of any stock exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage; and

(ii)

a disclosure statement prepared by the Corporation describing the Rights,

provided that a Nominee shall be sent the materials provided for in (i) and (ii) only 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 it with such information and documentation as the Corporation considers advisable.

(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, at its principal office in the city of Toronto or any other office of the Rights Agent or Co-Rights Agent in the cities designated from time to time for that purpose by the Corporation with the approval of the Rights Agent:

(i)

the Rights Certificate evidencing such Rights;

(ii)

an election to exercise (an “Election to Exercise”) substantially in the form attached to the Rights Certificate duly completed, and executed in a manner acceptable to the Rights Agent; and

(iii)

payment by certified cheque, banker's draft or money order payable to the order of the Corporation, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being exercised.

(e)

Upon receipt of a Rights Certificate which is accompanied by an appropriately completed and duly executed Election to Exercise (which does not indicate that such Right is null and void as provided by Subsection 3.1(b)) and payment as set forth in Subsection 2.2(d), the Rights Agent (unless otherwise instructed by the Corporation) will thereupon promptly:

(i)

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

(ii)

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

(iii)

when appropriate, requisition from the Corporation the appropriate payment by certified cheque, banker's draft or money order, if any, to be paid in lieu of issuing fractional Common Shares;

(iv)

when appropriate, after receipt of such certified cheque, banker's draft or money order, deliver such funds to, or to the order of, the registered holder of the Rights Certificate; and

(v)

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

(f)

If 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 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 delivered upon the exercise of Rights shall, at the time of delivery of the certificates for such Common Shares (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered as fully paid and non assessable;

(ii)

take all such action as may reasonably be considered to be necessary and within its power to comply with any applicable requirements of the Business Corporations Act, the Securities Act (Ontario), the U.S. Exchange Act, the United States Securities Act of 1933, as amended, and comparable legislation of each of the provinces and territories of Canada and states of the United States of America, or the rules and regulations thereunder or any other applicable law, rule or regulation, in connection with the issuance and delivery of the Rights, the Rights Certificates and the issuance of any Common Shares upon exercise of the Rights;

(iii)

use reasonable efforts to cause all Common Shares issued upon exercise of the Rights to be listed on the stock exchanges on which the Common Shares are listed at that time;

(iv)

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

(v)

pay when due and payable, if applicable, any and all federal, provincial, state and municipal taxes (not in the nature of income, capital gains or withholding taxes) and charges which may be payable in respect of the original issuance or delivery of the Rights Certificates or certificates for Common Shares issued upon the exercise of 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 of Rights or the issuance or delivery of certificates for Common Shares issued upon the exercise of Rights, in a name other than that of the holder of the Rights being transferred or exercised.

2.3

Adjustments to Exercise Price; Number of Rights

(a)

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 and in Article 3.

(b)

In the event that the Corporation shall at any time after the Record Time and prior to the Expiration Time:

(i)

declare or pay a dividend on the Common Shares payable in Voting Shares or Convertible Securities in respect thereof 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 Voting Shares (or Convertible Securities in respect thereof) in respect of, in lieu of or in exchange for existing Common Shares, whether in a reclassification, amalgamation, statutory arrangement, consolidation or otherwise;

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 purchasable upon the exercise of Rights) shall be adjusted as follows:

(A)

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

(1)

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 securities of the Corporation) (the “Expansion Factor”) that a holder of one Common Share immediately prior to such dividend, subdivision, change, combination or issuance would hold thereafter as a result thereof; and

(2)

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 allocated among the Common Shares with respect to which the original Rights were associated (if they remain outstanding) and the securities of the Corporation 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.

(B)

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 as a result thereof.

(c)

Adjustments pursuant to Subsection 2.3(b) shall be made successively, whenever an event referred to in Subsection 2.3(b) occurs.

(d)

If an event occurs which would require an adjustment under both this Section 2.3 and Section 3.1 hereof, the adjustment provided for in this Section 2.3 shall be in addition to, and shall be made prior to, any adjustment required pursuant to Section 3.1 hereof.

(e)

In the event the Corporation shall at any time after the Record Time and prior to the Separation Time issue any Common Shares otherwise than in a transaction referred to in Subsection 2.3(b), 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 Common Share.

(f)

In the event the Corporation shall, at any time after the Record Time and prior to the Expiration Time, fix a record date for the making of a distribution to all holders of Common Shares of rights or warrants entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares (or Convertible Securities in respect of Common Shares) at a price per Common Share (or, in the case of such a Convertible Security, having a conversion, exchange or exercise price per share (including the price required to be paid to purchase such Convertible Security)) less than 90% of the Market Price per Common Share on such record date, the Exercise Price in effect after such record date will equal the Exercise Price in effect immediately prior to such record date multiplied by a fraction:

(i)

of which the numerator shall be the number of Common Shares outstanding on such record date plus the number of Common Shares which the aggregate 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 Securities)) would purchase at such Market Price per Common Share; and

(ii)

of which the denominator shall be the number of Common Shares outstanding on such record date plus the number of additional Common Shares to be offered for subscription or purchase (or into which the Convertible Securities so to be offered are initially convertible, exchangeable or exercisable).

In case such subscription price is satisfied, in whole or in part, by consideration other than cash, the value of such consideration shall be as determined in good faith by the Board of Directors. Such adjustment shall be made successively whenever such a record date is fixed. To the extent that such rights or warrants are not exercised prior to the expiration thereof, the Exercise Price shall be readjusted in the manner contemplated above based on the number of Common Shares (or securities convertible into or exchangeable for Common Shares) actually issued on the exercise of such rights or warrants.

For purposes of this Agreement, the granting of the right to purchase Common Shares (whether from treasury or otherwise) pursuant to any dividend or interest reinvestment plan or any share purchase plan providing for the reinvestment of dividends or interest payable on securities of the Corporation or the investment of periodic optional payments or employee benefit or similar plans (so long as such right to purchase is in no case evidenced by the delivery of rights or warrants by the Corporation) shall not be deemed to constitute an issue of rights or warrants by the Corporation; provided, however, that in the case of any dividend or interest reinvestment or share purchase plan, 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.

(g)

In the event the Corporation shall at any time after the Record Time and prior to the Expiration Time fix a record date for the making of a distribution to all holders of Common Shares of (i) evidences of indebtedness or assets (other than a Regular Periodic Cash Dividend or a dividend paid in Common Shares, but including any dividend payable in securities other than Common Shares), (ii) rights or warrants entitling them to subscribe for or purchase Voting Shares (or Convertible Securities in respect of Voting Shares), at a price per Voting Share (or, in the case of a Convertible Security in respect of Voting Shares, having a conversion, exchange or exercise price per share (including the price required to be paid to purchase such Convertible Security)) less than 90% of the Market Price per Common Share on such record date (excluding rights or warrants referred to in Subsection 2.3(f)) or (iii) other securities of the Corporation, the Exercise Price in effect after such record date shall be equal to the Exercise Price in effect immediately prior to such record date less the fair market value (as determined in good faith by the Board of Directors) of the portion of the assets, evidences of indebtedness, rights or warrants or other securities so to be distributed applicable to each of the securities purchasable upon exercise of one Right. Such adjustment shall be made successively whenever such a record date is fixed.

(h)

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

(i)

the payment or effective date for the applicable dividend, subdivision, change, combination or issuance, in the case of an adjustment made pursuant to Subsection 2.3(b) above; and

(ii)

the record date for the applicable dividend or distribution, in the case of an adjustment made pursuant to Subsections 2.3(f) or 2.3(g) above, subject to readjustment to reverse the same if such distribution shall not be made.

(i)

In the event the Corporation shall at any time after the Record Time and prior to the Expiration Time issue any shares (other than Common Shares), or rights or warrants to subscribe for or purchase any such shares, or Convertible Securities in respect of any such shares, in a transaction referred to in any of subclauses 2.3(b)(i) to (iv) above, if the Board of Directors acting in good faith determines that the adjustments contemplated by Subsections 2.3(b), 2.3(f) and 2.3(g) above in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may from time to time, but subject to obtaining the prior approval of the holders of the Rights obtained as set forth in Subsection 5.5(b), determine what other adjustments to the Exercise Price, number of Rights or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding Subsections 2.3(b), 2.3(f) and 2.3(g) above, such adjustments, rather than the adjustments contemplated by Subsections 2.3(b), 2.3(f) and 2.3(g) above, shall be made upon the Board of Directors providing written certification thereof to the Rights Agent pursuant to Subsection 2.3(q).

(j)

Notwithstanding anything herein to the contrary, no adjustment of the Exercise Price shall be required unless such adjustment would require an increase or decrease of at least 1% in such Exercise Price; provided, however, that any adjustments which by reason of this Subsection 2.3(j)) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All adjustments to the Exercise Price made pursuant to this Section 2.3 shall be calculated to the nearest cent.

(k)

All Rights originally issued by the Corporation subsequent to any adjustment made to an 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 the Rights, all subject to further adjustment as provided herein.

(l)

Unless the Corporation shall have exercised its election, as provided in Subsection 2.3(m), upon each adjustment of an Exercise Price as a result of the calculations made in Subsections 2.3(f) and 2.3(g), 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 obtained by:

(i)

multiplying (A) the number of Common Shares covered by a Right immediately prior to such adjustment, by (B) the Exercise Price in effect immediately prior to such adjustment; and

(ii)

dividing the product so obtained by the Exercise Price in effect immediately after such adjustment.

(m)

The Corporation may elect on or after the date of any adjustment of an 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 adjustment of the number of Rights shall become the number of Rights obtained by dividing the relevant Exercise Price in effect immediately prior to adjustment of the relevant Exercise Price by the relevant Exercise Price in effect immediately after adjustment of the relevant Exercise Price. The Corporation shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the relevant Exercise Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least 10 calendar days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Subsection 2.3(m), the Corporation shall, as promptly as practicable, cause to be distributed to holders of record of Rights Certificates on such record date, Rights Certificates evidencing, subject to Section 5.5, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Corporation, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Corporation, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates so to be distributed shall be issued, executed and countersigned in the manner provided for herein and may bear, at the option of the Corporation, the relevant adjusted Exercise Price and shall be registered in the names of holders of record of Rights Certificates on the record date specified in the public announcement.

(n)

In any case in which this Section 2.3 shall require that an adjustment in an 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 of 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 relevant 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 Common Shares (fractional or otherwise) or other securities upon the occurrence of the event requiring such adjustment.

(o)

Notwithstanding anything in this Section 2.3 to the contrary, the Corporation shall be entitled to make such adjustments in the Exercise Price, in addition to those adjustments expressly required by this Section 2.3, as and to the extent that in its good faith judgment the Board of Directors shall determine to be advisable in order that any (i) subdivision or consolidation of the Common Shares, (ii) issuance wholly for cash of any Common Shares at less than the applicable Market Price, (iii) issuance wholly for cash of any Common Shares or securities that by their terms are exchangeable for or convertible into or give a right to acquire Common Shares, (iv) stock dividends, or (v) 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.

(p)

Irrespective of any adjustment or change in the securities purchasable upon exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to represent the securities so purchasable which were represented in the initial Rights Certificates issued hereunder.

(q)

Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation shall:

(i)

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

(ii)

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

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 any certificate for Common Shares is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Shares represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered (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 Person 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 Business Day on which the Common Share transfer books of the Corporation are open.

2.5

Execution, Authentication, Delivery and Dating of Rights Certificates

(a)

The Rights Certificates shall be executed on behalf of the Corporation by a senior officer. The signature of any such officer 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.

(b)

Promptly following 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 statement describing any adjustment to the Exercise Price, and the Rights Agent shall countersign (manually or by facsimile signature in a manner satisfactory to the Corporation) and deliver such Rights Certificates and any statement describing an adjustment to the Exercise Price to the holders of the Rights pursuant to Section 2.2 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)

After the Separation Time, the Corporation shall 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 and the Rights Agent hereby accepts such appointment. In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times.

(b)

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 Subsections 2.6(d) and 3.1(b) below, the Corporation will execute, and the Rights Agent will countersign, deliver and register, 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.

(c)

All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be 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.

(d)

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 fees and expenses of the Rights Agent) in connection therewith.

2.7

Mutilated, Lost, Stolen and Destroyed 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 fees and expenses of the Rights Agent) connected therewith.

(d)

Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any destroyed, lost or stolen Rights Certificate shall evidence a 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

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, the associated Common Shares).

2.9

Delivery and Cancellation of Certificates

All Rights Certificates surrendered upon exercise or for redemption, for 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 law, 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 such Rights, 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;

(c)

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

(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 its right to receive any fractional Rights or any fractional Common Shares or other securities upon exercise of a Right (except as provided herein); and

(f)

that, without the approval of any holder of Rights or Voting Shares and upon the sole authority of the Board of Directors acting in good faith, this Agreement may be supplemented or amended from time to time as provided herein.

ARTICLE 3 - ADJUSTMENTS TO THE RIGHTS

3.1

Flip-in Event

(a)

Subject to Sections 3.1(b) and 5.1, in the event that prior to the Expiration Time a Flip-in Event occurs, 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 as have an aggregate Market Price on the date of consummation or occurrence of such Flip-in Event equal to twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 in the event that, after such date of consummation or occurrence, an event of a type analogous to any of the events described in Section 2.3 shall have occurred with respect to such Common Shares).

(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 and the Stock Acquisition Date, or which may thereafter be Beneficially Owned, by:

(i)

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

(ii)

a transferee or other successor in title, directly or indirectly, (a “Transferee”) of Rights held by an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Associate or Affiliate of an Acquiring Person) in a transaction that the Board of Directors has determined is part of a plan, arrangement or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or any Affiliate or Associate of an Acquiring Person) that has the purpose or effect of avoiding clause (i),

shall become null and void without any further action, and any holder of such Rights (including any Transferee) shall thereafter have no right to exercise such Rights under any provisions of this Agreement and further shall thereafter not have any rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise. The holder of any Rights represented by a Rights Certificate which is submitted to the Rights Agent upon exercise or for registration of transfer or exchange which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not void under this subsection shall be deemed to be an Acquiring Person for the purposes of this section and such Rights shall be null and void.

(c)

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

“The Rights represented by this Rights Certificate are or were beneficially owned by a Person who was an Acquiring Person or an Affiliate or an Associate of an Acquiring Person or a Person acting jointly or in concert with any of them (as such terms are defined in the Rights Agreement). This Rights Certificate and the Rights represented hereby shall be void in the circumstances specified in Subsection 3.1(b) of the Rights Agreement.”

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 be required to impose such legend only if instructed to do so by the Corporation or if a holder fails to certify upon transfer or exchange in the space provided to do so. The issuance of a Rights Certificate without the legend referred to in this subsection will not affect the application of subsection 3.1(b).

(d)

From and after the Separation Time, the Corporation shall do all such acts and things necessary and within its power to ensure compliance with the provisions of this Section 3.1 including, without limitation, all such acts and things as may be required to satisfy the requirements of the Business Corporations Act, the Securities Act (Ontario) and the securities laws or comparable legislation in each of the provinces of Canada and in any other jurisdiction where the Corporation is subject to such laws and the rules of the stock exchanges where the Common Shares are listed at such time in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.

3.2

Fiduciary Duties of the Board of Directors of the Corporation

For clarification it is understood that nothing contained in this Article 3 shall be considered to affect the obligations of the Board of Directors to exercise its fiduciary duties. Without limiting the generality of the foregoing, nothing contained herein shall be construed to suggest or imply that the Board of Directors shall not be entitled to recommend that holders of the Voting Shares reject or accept any Take-over Bid or take any other action including, without limitation, the commencement, prosecution, defence or settlement of any litigation and the submission of additional or alterative Take-over Bids or other proposals to the shareholders of the Corporation with respect to any Take-over Bid or otherwise that the Board of Directors believes is necessary or appropriate in the exercise of its fiduciary duties.

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 hereof, and the Rights Agent hereby accepts such appointment. The Corporation may from time to time appoint such co-rights agents (“Co-Rights Agents”) as it may deem necessary or desirable. 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. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and other disbursements reasonably incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder, including the reasonable fees and disbursements of counsel and other experts consulted by the Rights Agent pursuant to Subsection 4.3(a). The Corporation also agrees to indemnify the Rights Agent for, and to hold it harmless against, any loss, liability, or expense, incurred without gross negligence, bad faith or wilful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending against any claim of liability, which right to indemnification will survive the termination of this Agreement or the resignation or removal of the Rights Agent.

(b)

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

(c)

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, 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 or consolidation to which the Rights Agent or any successor Rights Agent is a party, or any corporation succeeding to the shareholder 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 document 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.

(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, by all of which the Corporation and the holders of Rights Certificates, by their acceptance thereof, shall be bound:

(a)

The Rights Agent may consult with legal counsel (who may be legal counsel for the Corporation) and the opinion of such counsel will be full and complete authorization and protection to the Rights Agent as to any action taken or omitted by it in good faith and in accordance with such opinion; the Rights Agent may also, with the approval of the Corporation (such approval not to be unreasonably withheld), 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 (at the expense of the Corporation) and the Rights Agent shall be entitled to 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 a person believed by the Rights Agent to be a senior officer of the Corporation and delivered to the Rights Agent; and such certificate will be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.

(c)

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

(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 or in the certificates for Common Shares, or the Rights Certificates (except its countersignature thereof) or be required to verify the same, and all such statements and recitals are and will be deemed to have been made by the Corporation only.

(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 Common Share certificate, or Rights Certificate (except its countersignature thereon) nor will it be responsible for any breach by the Corporation of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible for any change in the exercisability of the Rights (including the Rights becoming void pursuant to Subsection 3.1(b) hereof or any adjustment required under the provisions of Section 2.3) hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Section 2.3 describing any such adjustment or any written notice from the Corporation or any holder that a Person has become an Acquiring Person); 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 any Common Shares, when issued, being duly and validly authorized, issued and delivered as fully paid and non assessable.

(f)

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

(g)

The Rights Agent is hereby authorized and directed to accept instructions with respect to the performance of its duties hereunder from any individual believed by the Rights Agent to be a senior 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. It is understood that instructions to the Rights Agent shall, except where circumstances make it impractical or the Rights Agent otherwise agrees, be given in writing and, where not in writing, such instructions shall be confirmed in writing as soon as reasonably practicable after the giving of such instructions.

(h)

Subject to applicable law, the Rights Agent and any shareholder or director, officer or employee of the Rights Agent may buy, sell or deal in Common Shares, Rights or other securities of the Corporation or become pecuniarily interested in any transaction in which the Corporation may be interested, or contract with or lend money to the Corporation or otherwise act as fully and freely as though it were not 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.

(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 act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.

4.4

Change of Rights Agent

The Rights Agent may resign and be discharged from its duties under this Agreement by giving 60 days' prior written notice (or such lesser notice as is acceptable to the Corporation) to the Corporation, to each transfer agent of Common Shares and to the holders of the Rights, all in accordance with Section 5.9 and at the expense of the Corporation. The Corporation may remove the Rights Agent by giving 30 days' prior written notice to the Rights Agent, to each transfer agent of the Common Shares and to the holders of the Rights in accordance with Section 5.9. 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 or by the holder of any Rights (which holder shall, with such notice, submit such holder's Rights Certificate for inspection of the Corporation), then the holder of any Rights 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, must be a corporation incorporated under the laws of Canada or a province thereof and authorized to carry out the duties of the Rights Agent specified in this Agreement 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, upon payment of any outstanding fee, 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 the successor Rights Agent, as the case may be.

ARTICLE 5 - MISCELLANEOUS

5.1

Redemption of Rights

(a)

Until the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to Section 5.2 and provided that the provisions of Subsection 5.2(c) are not applicable to such Flip-in Event, the Board of Directors, with the prior approval of the holders of Voting Shares given in accordance with Subsection 5.2(e) or Subsection 5.1(g), as applicable, may 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 if an event of a 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”).

(b)

The Board of Directors shall, without further formality, be deemed to have elected to redeem the Rights at the Redemption Price on the date that a Person who has made a Permitted Bid, a Competing Permitted Bid or a Take-over Bid in respect of which the Board of Directors has waived the application of Section 3.1 takes up and pays for Voting Shares pursuant to the terms and conditions of such Permitted Bid, Competing Permitted Bid or Take-over Bid, as the case may be.

(c)

Where a Take-over Bid that is not a Permitted Bid or Competing Permitted Bid expires, 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.

(d)

If the Board of Directors elects or is deemed to have elected to redeem the Rights, (i) 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, and (ii) subject to Subsection 5.1(f) no further Rights shall be issued.

(e)

Within ten Business Days after the Board of Directors electing or having been deemed to have elected 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 share register maintained by the Corporation’s transfer agent or transfer agents 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, except in connection with the purchase of Common Shares prior to the Separation Time.

(f)

Upon the Rights being redeemed pursuant to this Section 5.1, Rights may be reissued under this Agreement to holders of record of Common Shares immediately following such redemption, and thereafter, 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 such reissued Rights shall, without any further formality, be attached to the outstanding Common Shares in the same manner as prior to the occurrence of such Separation Time.

(g)

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

5.2

Waiver of Flip-In Event

(a)

Subject to Section 5.2(c), at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to this Section 5.2, the Board of Directors may, with the prior approval of the holders of Voting Shares given in accordance with Subsection 5.2(e), waive the application of Section 3.1 to such Flip-in Event by written notice delivered to the Rights Agent. If the Board of Directors proposes such a waiver, the Board of Directors will extend the Separation Time to a date subsequent to and not more than ten Business Days following the meeting of holders of Voting Shares called to approve such waiver.

(b)

Notwithstanding and without limiting the generality of Subsection 5.2(a), the Board of Directors may waive the application of Section 3.1 to a Flip-in Event provided that the following conditions are satisfied:

(i)

the Board of Directors has determined that the Acquiring Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person; and

(ii)

such Acquiring Person has reduced its Beneficial Ownership of Voting Shares such that at the time of the granting of the waiver pursuant to this Subsection 5.2(b), it is no longer an Acquiring Person;

and, in the event of any such waiver, for the purposes of this Agreement, such Flip-in Event shall be deemed not to have occurred and the Separation Time shall be deemed not to have occurred as a result of such Person having inadvertently become an Acquiring Person. Written notice of any such waiver shall be given to the Rights Agent as soon as is reasonably practicable.

(c)

Until the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to this Section 5.2, upon written notice to the Rights Agent, the Board of Directors may, with the prior consent of the holders of Voting Shares given in accordance with Subsection 5.2(e), determine, 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 holders of record of Voting Shares and otherwise than in the circumstances set forth in Subsection 5.2(b), to waive the application of Section 3.1, to such Flip-in Event. In the event that the Board of Directors proposes such a waiver, the Board of Directors shall extend the Separation Time to a date subsequent to and not more than ten Business Days following the meeting of shareholders called to approve such waiver.

(d)

Until the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to this Section 5.2, upon written notice delivered to the Rights Agent, the Board of Directors may determine to waive the application of Section 3.1 to any Flip-in Event provided that the Flip-in Event would occur by reason of a Take-over Bid made by take-over bid circular sent to all holders of Voting Shares and provided further that if the Board of Directors waives the application of Section 3.1 to such Flip-in Event, 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 made by take-over bid circular to all holders of Voting Shares which is made prior to the expiry of any Take-over Bid (as the same may be extended from time to time) made by take-over bid circular in respect of which a waiver is, or is deemed to have been, granted under this Subsection 5.2(d).

(e)

If a redemption of Rights pursuant to Subsection 5.1(a) or a waiver of a Flip-in Event pursuant to Subsection 5.2(c) is proposed at any time prior to the Separation Time, such redemption or waiver shall be submitted for approval to the holders of Voting Shares. Such approval shall be deemed to have been given if the redemption or waiver is approved by the affirmative vote of a majority of the votes cast by Independent Shareholders represented in person or by proxy at a meeting of such holders duly held in accordance with applicable laws and the Corporation’s by- laws.

5.3

Expiration

No person will have any rights pursuant to this Agreement or in respect of any Right after the Expiration Time, except in respect of any right to receive cash, securities or other property which has accrued at the Expiration Time and except as specified in Subsections 4.1(a) and 4.1(b) hereof.

5.4

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 its Board of Directors to reflect any adjustment or change in the number or kind or class of shares purchasable upon exercise of Rights made in accordance with the provisions of this Agreement.

5.5

Supplements and Amendments

(a)

Subject to Subsections 5.5(b) and (c) and this Subsection 5.5(a), the Corporation may from time to time amend, vary or delete any of the provisions of this Agreement and the Rights provided that no amendment, variation or deletion made on or after the date of the first meeting of Shareholders at which the resolution referred to in Section 5.16 is to be considered shall be made without the prior consent of the holders of the Rights, given as provided in Subsection 5.4(b) below, except that amendments, variations or deletions made for any of the following purposes shall not require such prior approval but shall be subject to subsequent ratification in accordance with Subsection 5.4(b):

(i)

in order to make such changes as are necessary in order to maintain the validity of this Agreement and the Rights as a result of any change in any applicable legislation, regulations or rules;

(ii)

in order to make such changes as are necessary in order to cure any clerical or typographical error.

(b)

Any amendment, variation or deletion made by the Board of Directors pursuant to Subsection 5.4(a) shall:

(i)

if made prior to the Separation Time, be submitted to the shareholders of the Corporation at the next meeting of shareholders and the shareholders may, by resolution passed by a majority of the votes cast by Independent Shareholders who vote in respect of such amendment, variation or deletion, confirm or reject such amendment or supplement; or

(ii)

if made after the Separation Time, be submitted to the holders of Rights at a meeting to be held on a date not later than the date of the next meeting of shareholders of the Corporation and the holders of Rights may, by resolution passed by a majority of the votes cast by the holders of Rights which have not become void pursuant to Subsection 3.1(b) who vote in respect of such amendment, variation or deletion, confirm or reject such amendment or supplement.

Any amendment, variation or deletion pursuant to Subsection 5.4(a) shall be effective only when so consented to by the holders of Voting Shares or Rights, as applicable (except in the case of an amendment, variation or deletion referred to in any of Clauses 5.4(a)(i) or (ii), which shall be effective from the date of the resolution of the Board of Directors adopting such amendment, variation or deletion and shall continue in effect until it ceases to be effective (as in this paragraph described) and, where such amendment, variation or deletion is confirmed, it shall continue in effect in the form so confirmed). If an amendment, variation or deletion pursuant to Clause 5.4(a)(i) or (ii) is rejected by the shareholders or the holders of Rights or is not submitted to the shareholders or holders of Rights as required, then such amendment, variation or deletion shall cease to be effective from and after the termination of the meeting at which it was rejected or to which it should have been but was not submitted or from and after the date of the meeting of holders of Rights that should have been but was not held, and no subsequent resolution of the Board of Directors to amend, vary or delete any provision of this Agreement to substantially the same effect shall be effective until confirmed by the shareholders or holders of Rights, as the case may be.

(c)

For greater certainty, (i) no amendment, variation or deletion to the provisions of Article 4 or the rights, duties, obligations or indemnities of the Rights Agent shall be made except with the concurrence of the Rights Agent thereto, and (ii) neither the exercise by the Board of Directors of any power or discretion conferred on it hereunder nor the making by the Board of Directors of any determination or the granting of any waiver it is permitted to make or give hereunder shall constitute an amendment, variation or deletion of the provisions of this Agreement or the Rights, for purposes of this Section 5.4 or otherwise.

(d)

The approval, confirmation or consent of the holders of Rights with respect to any matter arising hereunder shall be deemed to have been given if the action requiring such approval, confirmation or consent 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 or which, prior to the Separation Time, are held otherwise than by Independent Shareholders) shall be entitled to one vote, and the procedures for the calling, holding and conduct of the meeting shall be those, as nearly as may be, which are provided in the Corporation's by-laws and the Business Corporations Act with respect to meetings of shareholders of the Corporation.

5.6

Fractional Rights and Fractional Shares

(a)

The Corporation will not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights. After the Separation Time there shall be paid, in lieu of such fractional Rights, to the registered holders of the Rights Certificates with regard to which fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the Market Price of a whole Right.
