ARTICLE 2

THE RIGHTS

Legend on Common Share Certificates

2.1

Certificates for the Common Shares that are issued after the Record Time but prior to the earlier of the Separation Time and the Expiration Time, shall also represent and evidence 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 (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 as of December 13, 2011 (the “Shareholder Rights Plan Agreement”), between Stellar Biotechnologies Inc. (the “Corporation”) and Computershare Investor Services Inc., 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 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.

Certificates representing Common Shares that are issued and outstanding at the Record Time, which as at the Effective Date represent Common Shares, shall also represent and evidence one Right for each Common Share evidenced thereby, notwithstanding the absence of the foregoing legend, until the close of business on the earlier of the Separation Time and the Expiration Time.

Initial Exercise Price; Exercise of Rights; Detachment of Rights

2.2

(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 (and the Exercise Price and number of Common Shares are subject to adjustment as set forth below). Notwithstanding any other provision of this Agreement, any Rights held by the Company 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)

each Right will be represented and evidenced by the certificate for the associated Common Share of the Company registered in the name of the holder thereof (which certificate shall also 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 of the Company.

(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 of the Company.

Promptly following the Separation Time, the Company will prepare and the Rights Agent will mail to each holder of record of Common Shares as of the Separation Time (other than an Acquiring Person 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 Company (the Company hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):

(i)

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

(ii)

a disclosure statement describing the Rights, provided that a Nominee shall be sent the materials provided for in (i) and (ii) in respect of all Common Shares of the Company held of record by it which are not Beneficially owned by an Acquiring Person.

(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:

(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 appropriately completed and executed by the holder or his executors or administrators or other personal representatives or his or their legal attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Rights Agent; and

(iii)

payment by certified cheque, banker’s draft or money order payable to the order of the Company, 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, together with a completed Election to Exercise executed in accordance with §2.2(d)(ii), which does not indicate that such Right is null and void as provided by §3.1(b), and payment as set forth in §2.2(d)(iii), the Rights Agent (unless otherwise instructed by the Company in the event that the Company is of the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:

(i)

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

(ii)

when appropriate, requisition from the Company the amount of cash to be paid in lieu of issuing fractional Common Shares;

(iii)

after receipt of the certificates referred to in §2.2(e)(i), deliver the same to or to 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 §2.2(e)(ii) to or to the order of the registered holder of such Rights Certificate; and

(v)

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

(g)

The Company 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 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 be necessary and within its power to comply with the requirements of the Business Corporations Act and the Securities Act, and the applicable securities laws or comparable legislation of each of the provinces and territories 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;

(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 Stock Acquisition Date;

(iv)

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

(v)

pay when due and payable, if applicable, any and all United States, federal, provincial, state and municipal transfer taxes and charges (not including any income or capital taxes of the holder or exercising holder or any liability of the Company to withhold tax) which may be payable in respect of the original issuance or delivery of the Rights Certificates, or certificates for Common Shares to be issued upon exercise of any Rights, provided that the Company shall not be required to pay any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares in a name other than that of the holder of the Rights being transferred or exercised; and

(vi)

after the Separation Time, except as permitted by §5.1 or §5.4, not take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.

Adjustments to Exercise Price; Number of Rights

2.3

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 §2.3.

(a)

In the event the Company shall at any time after the Record 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 Company) other than pursuant to any optional stock dividend program;

(ii)

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

(iii)

consolidate or change all of 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 Company) in respect of, in lieu of or in exchange for all of the existing outstanding Common Shares except as otherwise provided in this §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 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 §2.3 and §3.1(a), the adjustment provided for in this §2.3 shall be in addition to, and shall be made prior to, any adjustment required under §3.1(a).

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

(v)

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

(vi)

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 capital stock) will have exactly one Right associated with it.

For greater certainty, 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 of such dividend, subdivision, change, consolidation or issuance.

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

If the Company at any time after the Record Time and prior to the Separation Time issues any Common Shares otherwise than in a transaction referred to in this §0, each such Common Share so issued shall automatically have one new Right associated with it, which Right shall be represented and evidenced by the certificate representing such associated Common Share.

(b)

If the Company at any time after the Record Time and prior to the Separation Time fixes a record date for the issuance of rights, options or warrants to all holders of Common Shares entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for or carrying a right to purchase Common Shares) at a price per Common Share (or, if a security convertible into or exchangeable for or carrying a right to purchase or subscribe for Common Shares, having a conversion, exchange or exercise price, including the price required to be paid to purchase such convertible or exchangeable security or right per share) less than the Market Price per Common Share on such record date, the Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction:

(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 or exchangeable securities or rights so to be offered, including the price required to be paid to purchase such convertible or exchangeable securities or rights) would purchase at such Market Price per Common Share; and

(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 or exchangeable securities or rights 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 plan, stock option plan, defined or restricted stock unit plan or any similar plan shall be deemed not to constitute an issue of rights, options or warrants by the Company.

(c)

If the Company at any time after the Record Time and prior to the Separation Time fixes 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 or amalgamation) of evidences of indebtedness, cash (other than an annual cash dividend or a dividend referred to in §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 §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

(ii)

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

(iii)

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 §2.3(d) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under §2.3 shall be made to the nearest cent or to the nearest ten-thousandth of a share. Notwithstanding the first sentence of this §2.3(d), any adjustment required by §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)

Whenever an adjustment to the Exercise Price or a change in the securities purchasable upon exercise of the Rights is made pursuant to this §2.3, the Company shall promptly and in any event, where such change or adjustment occurs prior to the Separation Time, not later than the Separation Time:

(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.

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 such adjustment or change.

(f)

If the Company at any time after the Record Time and prior to the Separation Time issue any shares in its capital (other than Common Shares), or rights, options or warrants to subscribe for or purchase any such shares, or securities convertible into or exchangeable for any such capital stock in a transaction referred to in §2.3(a)(i) or (iv) or §2.3(b) or (c) above, if the Board of Directors acting in good faith determines that the adjustments contemplated by §0, (b) and (c) above 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 §0, (b) and (c) above, such adjustments, rather than the adjustments contemplated by §0, (b) and (c) above, shall be made. Subject to the prior consent of the holders of the Voting Shares or the Rights as set forth in §5.4(b) or (c), the Company and the Rights Agent shall have authority to amend this Agreement as appropriate to provide for such adjustments.

(g)

Each Right originally issued by the Company 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.

(h)

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.

(i)

In any case in which this §2.3 requires that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Company 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 Company, if any, issuable upon such exercise over and above the number of Common Shares and other securities of the Company, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, however, that the Company 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.

(j)

Notwithstanding anything contained in this §2.3 to the contrary, the Company shall be entitled to make such reductions in the Exercise Price, in addition to those adjustments expressly required by this §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)

stock dividends; or

(iv)

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

hereafter made by the Company to holders of its Common Shares, shall not be taxable to such shareholders.

Date on Which Exercise Is Effective

2.4

Each Person in whose name any certificate for Common Shares or other securities, if applicable, is issued 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 certificate shall be dated the date upon which the Rights Certificate evidencing such Rights was duly surrendered in accordance with §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 Company 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 Company are open.

Execution, Authentication, Delivery and Dating of Rights Certificates

2.5

(a)

The Rights Certificates shall be executed on behalf of the Company by its Chairman of the Board, Chief Executive Officer, President or Chief Financial Officer and by its Secretary under the corporate seal of the Company reproduced thereon. The signature of any of these officers on the Rights Certificates may be manual or facsimile. Rights Certificates bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, 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 Company learns of the Separation Time, the Company will notify the Rights Agent of such Separation Time and will deliver Rights Certificates executed by the Company to the Rights Agent for countersignature, and the Rights Agent shall countersign manually or by facsimile signature (in a manner satisfactory to the Company) and send such Rights Certificates to the holders of the Rights pursuant to §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.

Registration, Transfer and Exchange

2.6

(a)

The Company will cause to be kept a register (the “Rights Register”) in which, subject to such reasonable regulations as it may prescribe, the Company 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 Company 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.

After the Separation Time and prior to the Expiration Time, upon surrender for registration of a transfer or exchange of any Rights Certificate, and subject to the provisions of §2.6(c), the Company will execute, and the Rights Agent will countersign, register 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.

(b)

All Rights issued upon any registration of a transfer or exchange of Rights Certificates shall be the valid obligations of the Company, 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 a transfer or exchange shall be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company or the Rights Agent, as the case may be, duly executed by the holder thereof or such holder’s attorney duly authorized in writing and shall be guaranteed by a chartered bank or an eligible guarantor institution with membership in an approved signature guarantee medallion program. As a condition to the issuance of any new Rights Certificate under this §2.6, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the reasonable fees and expenses of the Rights Agent) connected therewith.

Mutilated, Destroyed, Lost and Stolen Rights Certificates

2.7

(a)

If any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the Company shall execute and the Rights Agent shall countersign register 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 Company 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 Company or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Company shall execute and upon the Company 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 §2.7, the Company 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)

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

Persons Deemed Owners of Rights

2.8

The Company, the Rights Agent and any agent of the Company 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).

Delivery and Cancellation of Certificates

2.9

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 Company may at any time deliver to the Rights Agent for cancellation any Rights Certificates previously countersigned and delivered hereunder which the Company 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 §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 Company.

Agreement of Rights Holders

2.10

Every holder of Rights, by accepting the Rights, consents and agrees with the Company 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;

(d)

that prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) for registration of a transfer, the Company, the Rights Agent and any agent of the Company 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 Company or the Rights Agent) for all purposes whatsoever, and neither the Company 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 §5.4, without the approval of any holder of Rights or Voting Shares and upon the sole authority of the Board of Directors, acting in good faith, this Agreement may be supplemented or amended from time to time to cure any ambiguity or to correct or supplement any provision contained herein which may be inconsistent with the intent of this Agreement or is otherwise defective, as provided herein; and

(g)

that notwithstanding anything in this Agreement to the contrary, neither the Company nor the Rights Agent shall have any liability to any holder of a Right 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.

Rights Certificate Holder Not Deemed a Shareholder

2.11

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 Company 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 Company or any right to vote at any meeting of shareholders of the Company whether for the election of directors or otherwise or upon any matter submitted to holders of Common Shares or any other shares of the Company at any meeting thereof, or to give or withhold consent to any action of the Company, or to receive notice of any meeting or other action affecting any holder of Common Shares or any other shares of the Company 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

Flip-In Event

3.1

(a)

Subject to §3.1(b) and §5.1, in the event that prior to the Expiration Time a Flip-in Event shall occur, then thereafter, each Right shall constitute, effective at the close of business on the tenth Trading Day after the Stock Acquisition Date, the right to purchase from the Company, upon exercise thereof in accordance with the terms hereof, that number of Common Shares having an aggregate Market Price on the date of consummation or occurrence of such Flip-in Event equal to two times 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 §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 §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 Stock 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 with any Affiliate or Associate of an Acquiring Person); or

(ii)

a transferee of Rights, directly or indirectly, from an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or with any Affiliate or Associate of an Acquiring Person), where such transferee becomes a transferee concurrently with or subsequent to the Acquiring Person becoming such in a transfer that the Board of Directors has determined is part of a plan, arrangement or scheme of an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or with any Associate or Affiliate of an Acquiring Person), that has the purpose or effect of avoiding §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. The holder of any Rights represented by a Rights Certificate which is submitted to the Rights Agent upon exercise or for registration or transfer or exchange which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not null and void under this §3.1(b) shall be deemed to be an Acquiring Person for the purposes of this §3.1 and such Rights shall become null and void.

(c)

From and after the Separation Time, the Company shall do all such acts and things as shall be necessary and within its power to ensure compliance with the provisions of §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, the U.S. Securities Act, the U.S. Exchange Act and the applicable securities laws or comparable legislation in each of the provinces and territories of Canada and States of the United States in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.

(d)

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

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 with an Affiliate or Associate of an Acquiring Person. This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances specified in §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 Company 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 §3.1(d) shall be of no effect on the provisions of §3.1(b).

ARTICLE 4

THE RIGHTS AGENT

General

4.1

(a)

The Company hereby appoints the Rights Agent to act as agent for the Company and the holders of the Rights in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Company may from time to time appoint such co-Rights Agents (“Co-Rights Agents”) as it may deem necessary or desirable, subject to the prior approval of the Rights Agent. In the event the Company appoints one or more Co-Rights Agents, the respective duties of the Rights Agent and Co-Rights Agents shall be as the Company may determine with the approval of the Rights Agent and the Co-Rights Agent. The Company also agrees to indemnify the Rights Agent its officers, directors and employees for, and to hold it harmless against, any loss, liability, or expense, incurred without negligence, bad faith or willful misconduct on the part of the Rights Agent, for anything done or omitted by the Rights Agent in connection with the acceptance and administration of this Agreement, including the costs and expenses of defending against any claim of liability, which right to indemnification will survive the termination of this Agreement.

(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 Company, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, opinion, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.

(c)

The Company 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 Company; provided that failure to inform the Rights Agent of any such events, or any defect therein shall not affect the validity of any action taken hereunder in relation to such events.

(d)

The Company agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time on demand of the Rights Agent, its reasonable expenses and counsel fees and any other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder.

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

4.2

(a)

Any corporation into which the Rights Agent may be merged or amalgamated or with which it may be consolidated, or any corporation resulting from any merger, amalgamation, statutory arrangement or consolidation to which the Rights Agent is a party, or any corporation succeeding to the shareholder or stockholder services business of the Rights Agent, will be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation is eligible for appointment as a successor Rights Agent under the provisions of §4.4 hereof. If at the time such successor Rights Agent succeeds to the agency created by this Agreement any of the Rights Certificates have been countersigned but not delivered, 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 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.

(b)

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

Duties of Rights Agent

4.3

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

(a)

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

(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 Company 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 the Chairman of the Board, President, any Vice President, Treasurer or Secretary of the Company 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)

notwithstanding anything to the contrary, the Rights Agent will be liable hereunder for its own gross negligence, bad faith or willful 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, but all such statements and recitals are and will be deemed to have been made by the Company 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 certificate for a Common Share or Rights Certificate (except its countersignature thereof); nor will it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Rights Certificate; nor will it be responsible for any change in the exerciseability of the Rights (including the Rights becoming void pursuant to §3.1(b) hereof) or any adjustment required under the provisions of §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 §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)

the Company 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 in writing with respect to the performance of its duties hereunder from any individual believed by the Rights Agent to be the Chairman of the Board, Chief Executive Officer, President, any Vice President, Treasurer or Corporate Secretary of the Company, 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 Company or have a pecuniary interest in any transaction in which the Company may be interested, or contract with or lend money to the Company 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 Company or for any other legal entity; and

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

Change of Rights Agent

4.4

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 Company) in writing mailed to the Company and to each transfer agent of Common Shares by registered or certified mail. The Company may remove the Rights Agent upon 60 days’ notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Shares by registered or certified mail. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Company will appoint a successor to the Rights Agent. If the Company fails to make such appointment within a period of 60 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent, then by prior written notice to the Company the resigning Rights Agent or the holder of any Rights (which holder shall, with such notice, submit such holder’s Rights Certificate, if any, for inspection by the Company), may apply to any court of competent jurisdiction for the appointment of a new Rights Agent. Any successor Rights Agent, whether appointed by the Company or by such a court, shall be a corporation incorporated under the laws of Canada or a province thereof authorized to act as the Rights Agent in the Province of British Columbia. 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 Company 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 §5.9. Failure to give any notice provided for in this §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.

ARTICLE 5

MISCELLANEOUS

Redemption, Waiver and Extension

5.1

(a)

The Board of Directors acting in good faith may waive the application of §3.1 in respect of the occurrence of any Flip-in Event if the Board of Directors has determined within ten Trading Days following a Stock Acquisition Date that a Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person under this Agreement and such Acquiring Person has reduced its Beneficial ownership of Voting Shares (or has entered into a contractual arrangement with the Company, acceptable to the Board of Directors, to do so within 30 days of the date such contractual arrangement is entered into) such that at the time the waiver becomes effective pursuant to this §5.1(a) it is no longer an Acquiring Person and, in the event that such a waiver is granted by the Board of Directors, 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 becoming an Acquiring Person.

(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 §3.1 to such particular Flip-in Event that would result from a Take Over Bid made by means of a Take Over Bid circular to all holders of Voting Shares (which for greater certainty shall not include the circumstances described in §5.1(a)), provided that if the Board waives the application of §3.1 to a particular Flip-in Event pursuant to this §5.1(b), the Board shall be deemed to have waived the application of §3.1 to any other Flip-in Event occurring by reason of any other Take Over Bid which is made by means of a Take Over Bid circular to all holders of Voting Shares prior to the expiry of any Take Over Bid (as the same may be extended from time to time) in respect of which a waiver is, or is deemed to have been granted under this §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 §5.1(b), outstanding Voting Shares, other than Voting Shares Beneficially owned at the date of the Permitted Bid, Competing Permitted Bid or Exempt Acquisition under §5.1(b) by such Person, 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 $0.0001 per Right appropriately adjusted in a manner analogous to the applicable adjustment provided for in §2.3 if an event of the type analogous to any of the events described in §2.3 shall have occurred (such redemption price being herein referred to as the “Redemption Price”).

(d)

With the prior approval of the holders of Voting Shares or Rights given in accordance with §5.4, the Board of Directors of the Company acting in good faith may, at its option, at any time prior to the provisions of §3.1 becoming applicable as a result of the occurrence of a Flip-in Event, elect to redeem all but not less than all of the then outstanding Rights at the Redemption Price appropriately adjusted in a manner analogous to the applicable adjustments provided for in §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 §2.3 shall have occurred.

(e)

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

(f)

If the Board of Directors is deemed under §5.1(c) to have elected or elects under §5.1(d) or (e) to redeem the Rights, then subject to §5.1(h), 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.

(g)

Within 10 Business Days after the Board of Directors is deemed under §5.1(c) to have elected or elects under §5.1(d) or (e) to redeem the Rights, the Company shall give notice of redemption to the holders of the then outstanding Rights by mailing such notice to each such holder at his last address as it appears upon the registry books of the Rights Agent or, prior to the Separation Time, on the registry books of the transfer agent for the Voting Shares. Any notice which is mailed in the manner 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.

(h)

Upon the Rights being redeemed pursuant to §5.1(e), 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.

(i)

The Company shall give prompt written notice to the Rights Agent of any waiver of the application of §3.1 pursuant to this §5.1.

Expiration

5.2

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

Issuance of New Rights Certificates

5.3

Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Company 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.

Supplements and Amendments

5.4

(a)

The Company may, prior to any shareholders’ meeting called to approve this Agreement, supplement or amend this Agreement without the approval of any holder of Rights or Voting Shares. Thereafter, the Company may from time to time supplement or amend this Agreement without the approval of any holders of Rights or Voting Shares to correct any clerical or typographical error or to maintain the validity of the Agreement as a result of a change in any applicable legislation or regulations or rules thereunder. Notwithstanding anything in this §5.4 to the contrary, no amendment shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such supplement or amendment.

(b)

Subject to §5.4(a), the Company may, with the prior consent of the holders of Voting Shares obtained as set forth below, at any time before the Separation Time, amend, vary or rescind any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally). Such consent shall be deemed to have been given if provided by the holders of Voting Shares at a Special Meeting, called and held in compliance with applicable laws and regulatory requirements and the requirements in the articles of the Company. Subject to compliance with any requirements imposed by the foregoing, consent shall be given if the proposed amendment, variation or rescission is approved by the affirmative vote of a majority of the votes cast by all holders of Voting Shares (other than any holder of Voting Shares who is an Offeror pursuant to a Take Over Bid that is not a Permitted Bid, a Competing Permitted Bid or an Exempt Acquisition, with respect to all Voting Shares Beneficially owned by such Person), represented in person or by proxy at the Special Meeting.

(c)

The Company may, with the prior consent of the holders of Rights obtained as set forth below, at any time after the Separation Time and before the Expiration Time, amend, vary or rescind any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally). Such consent shall be deemed to have been given if provided by the holders of Rights at a Rights Holders’ Special Meeting called and held in compliance with applicable laws and regulatory requirements and, to the extent possible, with the requirements in the articles of the Company applicable to meetings of holders of Voting Shares, applied mutatis mutandis.

(d)

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

(e)

Any amendments made by the Company to this Agreement pursuant to §5.4(a) which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation or regulations or rules thereunder, or are made at the request of a stock exchange on which the Common Shares are traded from time to time, shall:

(i)

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

(ii)

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

Any such amendment shall be effective from the date of the resolution of the Board of Directors adopting such amendment, until it is confirmed or rejected or until it ceases to be effective (as described in the next sentence) and, where such amendment is confirmed, it continues in effect in the form so confirmed. If such amendment 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 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 this Agreement to substantially the same effect shall be effective until confirmed by the shareholders or holders of Rights as the case may be.

Fractional Rights and Fractional Shares

5.5

(a)

The Company shall not be required to issue fractions of Rights or to distribute Rights Certificates which evidence fractional Rights and the Company shall not be required to pay any amount to a holder of record of Rights Certificates in lieu of such fractional Rights.

(b)

The Company shall not be required to issue fractions of Common Shares upon exercise of Rights or to distribute certificates which evidence fractional Common Shares and the Company shall not be required to pay any amount in lieu of such fractional Common Shares.

Rights of Action

5.6

Subject to the terms of this Agreement, all rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective holders of the Rights. Any holder of Rights, without the consent of the Rights Agent or of the holder of any other Rights, may, on such holder’s own behalf and for such holder’s own benefit and the benefit of other holders of Rights, enforce, and may institute and maintain any suit, action or proceeding against the Company to enforce such holder’s right to exercise such holder’s Rights or Rights to which such holder is entitled in the manner provided in such holder’s Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holder of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any Person subject to, this Agreement.

Regulatory Approvals

5.7

Any obligation of the Company or action or event contemplated by this Agreement or any amendments thereto shall be subject to the receipt of any requisite approval or consent from any governmental or regulatory authority, and without limiting the generality of the foregoing, necessary approvals of any stock exchange shall be obtained, such as to the issuance of Common Shares upon the exercise of Rights under §2.2(d).

Declaration as to Non-Canadian Holders

5.8

If in the opinion of the Board of Directors (who may rely upon the advice of counsel) any action or event contemplated by this Agreement would require compliance by the Company with the securities laws or comparable legislation of a jurisdiction outside Canada, the Board of Directors acting in good faith shall take such actions as it may deem appropriate to ensure such compliance. In no event shall the Company 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, in which such issue or delivery would be unlawful without registration of the relevant Persons or securities for such purposes.

5.14

If any term or provision hereof or the application thereof to any circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective only as to such jurisdiction and to the extent of such invalidity or unenforceability in such jurisdiction without invalidating or rendering unenforceable or ineffective the remaining terms and provisions hereof in such jurisdiction or the application of such term or provision in any other jurisdiction or to circumstances other than those as to which it is specifically held invalid or unenforceable.
