   **THE** RIGHTS 2.1

   Legend on Common Share Certificates
 Certificates representing Voting Shares which are issued after the Record Time but prior to the earlier of the Separation Time and the Expiration Time, will evidence one Right for each Voting Share represented thereby and shall have impressed, printed or written thereon or otherwise affixed thereto the following legend: "Until the Separation Time (as such term is defined in the Shareholder Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain rights as set forth in the shareholder rights agreement (the "Shareholder Rights Agreement") dated for reference October 18, 2010, between PETAQUILLA MINERALS LTD. (the "Corporation") and Computershare Investor Services Inc., as Rights Agent, the terms of which are hereby incorporated herein by reference and a copy of which is on file and may be inspected during normal business hours at the principal executive office of the Corporation. Under certain circumstances as set forth in the Shareholder Rights Agreement, such Rights may be amended, redeemed or exchanged, may expire, may lapse, may become void (if, in certain circumstances, they are "Beneficially Owned" by a person who is or becomes an "Acquiring Person", as such terms are defined in the Shareholder 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 Shareholder Rights Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor." Certificates representing Voting Shares that are issued and outstanding at the Record Time will also evidence one Right for each one Voting 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. 2.2

   Initial Exercise Price; Exercise of Rights; Detachment of Rights
  (a)

   Exercise Terms: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 Voting Share for the Exercise Price. Notwithstanding any other provision of this Agreement, any Rights held by the Corporation or any of its Subsidiaries will be void.(b)

  No Exercise Prior to Separation Time:Until the Separation Time:
  (i)

   the Rights will not be exercisable and no Right may be exercised; and(ii)

  each Right shall be evidenced by the certificate for the associated Voting Share registered in the name of the holder thereof (which certificate shall also be deemed to represent a Rights Certificate) and shall be transferable only together with, and shall be transferred by a transfer of, such associated Voting Share.
  (c)

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


---

Time: (i)

   the Rights are exercisable; and(ii)

  the registration and transfer of Rights will be separate from and independent of Voting Shares.
 Promptly following the Separation Time, the Corporation will prepare and the Rights Agent will mail to each holder of record of Voting 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 such Rights (a "Nominee")), at such holder's address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent for this purpose): (iii)

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

  a disclosure statement describing the Rights;
 provided that a Nominee shall be sent the materials provided for in (iii) and (iv) in respect of all Voting Shares of the Corporation held of record by it which are not Beneficially Owned by an Acquiring Person. (d)

  Manner of Exercise: 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 Right;(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 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 Corporation, in 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 and the transfer or delivery of Rights Certificates or the issuance or delivery of certificates of Voting Shares in a name otherthan that of the holder of the Rights being exercised.
  (e)

  Issue of Voting Shares: Upon receipt of a Rights Certificate, together with a completed Election to Exercise executed in accordance with Subsection 2.2(d)(ii) which does not indicate that such Right is null and void as provided by Subsection 3.1(b), and payment as set forth in Section 2.2(d)(iii), the Rights Agent (unless otherwise instructed by the Corporation in the event that the Corporation is of the opinion that the Rights cannot be exercised in accordance with this Agreement) will thereupon promptly:
  (i)

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


---

(ii)

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

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

  when appropriate, after receipt, deliver the cash referred to in clause 2.2(e)(ii) to or to the order of the registered holder of such Rights Certificate.
  (f)

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

  Covenants: The Corporation covenants and agrees to:
  (i)

   take all such action as may be necessary on its part and within its powers to ensure that all Voting Shares delivered upon exercise of Rights shall, at the time of delivery of the certificates evidencing such Voting Shares (subject to payment of the Exercise Price), be validly authorized, executed, issued and delivered and be fully paid and non-assessable;(ii)

   take all such action as may be necessary and within its power to comply with any applicable requirements of the Corporations Act, the Securities Act (Ontario), the Securities Act (British Columbia), the Securities Act (Quebec) and the Securities Act (Alberta), and the securities laws or comparable legislation of each of the other provinces and territories of Canada, and any other applicable law, rule or regulation thereof, in connection with the issue and delivery of the Rights Certificates and the issuance of the Voting Shares upon exercise of Rights;(iii)

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

   cause to be reserved and kept available out of the authorized and unissued Voting Shares, the number of Voting 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 federal, provincial and municipal transfer taxes and charges (not including any income or capital taxes of the holder or exercising holder or any liability of the Corporation to withhold tax) which may be payable in respect of the original issuance or delivery of the Rights Certificates, or certificates for the Voting Shares to be issued upon exercise of any Rights, provided that the Corporation shall not be required to pay any transfer tax or charge which may be payable in respect of any transfer involved in the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Voting 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 Section 5.1, not take (or permit any subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.
  (h)

  Authorized Capital: If the number of Common Shares which are not issued or reserved for issue is insufficient to permit the exercise in full of the Rights in accordance with this Section 2.2, then each Right, when such Right is aggregated with a sufficient number of Rights to acquire a whole number of Common Shares, will entitle the holder thereof, after the Separation Time, to purchase that number of Common Shares at the Exercise Price per Common Share equal to the


---

quotient determined by dividing the difference between the number of authorized Common Shares and the number of Common Shares then issued or allotted or reserved for issuance by the Corporation, by the number of Rights then outstanding. 2.3

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

   Share Reorganization:If the Corporation shall at any time after the date of this Agreement:
  (i)

   declare or pay a dividend on Voting Shares payable in Voting Shares (or other securities exchangeable for or convertible into or giving a right to acquire Voting Shares or other securities of the Corporation) other than pursuant to any optional stock dividend program;(ii)

   subdivide or change the then outstanding Voting Shares into a greater number of Voting Shares;(iii)

   consolidate or change the then outstanding Voting Shares into a smaller number of Voting Shares; or(iv)

  issue any Voting Shares for other securities exchangeable for or convertible into or giving a right to acquire Voting Shares or other securities of the Corporation or in respect of, in lieu of or in exchange for existing Voting Shares, except as otherwise provided in this Section 2.3,
 the Exercise Price and the number of Rights outstanding, or, if the payment or effective date therefor shall occur after the Separation Time, the securities purchasable upon exercise of Rights shall be adjusted as of the payment or effective date in the manner set forth below. 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 Voting Shares (or other capital stock) (the "Expansion Factor") that a holder of one Voting Share immediately prior to such dividend, subdivision, change, consolidation or issuance would hold thereafter as a result thereof; and(2)

  each Right held prior to such adjustment will become that number of Rights as results from the applications of the Expansion Factor,
 and the adjusted number of Rights will be deemed to be distributed among the Voting 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 Voting Share (or other capital stock) will have exactly one Right associated with it in effect following the payment or effective date of the event referred to in Clause 2.3(a)(i), (ii), (iii) or (iv), as the case may be. 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 Corporation shall issue any shares of capital stock other than Voting Shares in a transaction of a type described in Clause 2.3(a)(i) or (iv), shares of such capital stock shall be treated herein as nearly equivalent to Voting Shares as may be practicable and appropriate under the circumstances and the


---

Corporation and the Rights Agent agree to amend this Agreement in order to effect such treatment. In the event the Corporation shall at any time after the Record Time and prior to the Separation Time issue any Voting Shares otherwise than in a transaction referred to in this Subsection 2.3(a), each such Voting Share so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such associated Voting Share. (b)

  Rights Offering: If the Corporation shall at any time after the Record Time and prior to the Separation Time fix a record date for the issuance of rights, options or warrants to all holders of Voting Shares entitling them (for a period expiring within 21 calendar days after such record date) to subscribe for or purchase Voting Shares (or securities convertible into or exchangeable for or carrying a right to purchase Voting Shares) at a price per Voting Share (or, if a security convertible into or exchangeable for or carrying a right to purchase or subscribe for Voting 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 Voting 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 Voting Shares outstanding on such record date, plus the number of Voting Shares that the aggregate offering price of the total number of Voting 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 Voting Share; and(2)

  the denominator of which shall be the number of Voting Shares outstanding on such record date, plus the number of additional Voting 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 Voting Shares (or securities convertible into, or exchangeable or exercisable for Voting 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 Voting Shares (whether from treasury or otherwise) pursuant to the Dividend Reinvestment Plan or any employee benefit stock option or similar plans shall be deemed not to constitute an issue of rights, options or warrants by the Corporation; provided, however, that, in all such cases, the right to purchase Voting Shares is at a price per share of not less than 95% of the current market price per share (determined as provided in such plans) of the Voting Shares. (c)

  Special Distribution: If the Corporation shall at any time after the Record Time and prior to the Separation Time fix a record date for the making of a distribution to all holders of Voting 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 paid in Voting Shares, but including any dividend payable in securities other than Voting Shares), assets or rights, options or warrants (excluding those referred to in Subsection 2.3(b)), the


---

Exercise Price to be in effect after such record date shall be determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction: (i)

   the numerator of which shall be the Market Price per Voting Share on such record date, less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights), on a per share basis, of the portion of the cash, assets, evidences of indebtedness, rights, options or warrants so to be distributed; and(2)

  the denominator of which shall be such Market Price per Voting 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)

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

   three years from the date of the transaction which gives rise to such adjustment; or(2)

   the Expiration Date.
  (e)

   Discretionary Adjustment: If the Corporation shall at any time after the Record Time and prior to the Separation Time issue any shares of capital stock (other than Common Shares), or rights, options or warrants to subscribe for or purchase any such capital stock, or securities convertible into or exchangeable for any such capital stock, in a transaction referred to in Clause 2.3(a)(i) or (iv), if the Board of Directors acting in good faith determines that the adjustments contemplated by Subsections 2.3(a), (b) and (c) in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may determine what other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding Subsections 2.3(a), (b)and (c), such adjustments, rather than the adjustments contemplated by Subsections 2.3(a), (b)and (c), shall be made. The Corporation and the Rights Agent shall have authority without the approval of the holders of the Common Shares or the holders of Rights to amend this Agreement as appropriate to provide for such adjustments.(f)

   Benefit of Adjustments:Each Right originally issued by the Corporation subsequent to any adjustment made to the Exercise Price hereunder shall evidence the right to purchase, at the adjusted Exercise Price, the number of Voting Shares purchasable from time to time hereunder upon exercise of a Right immediately prior to such issue, all subject to further adjustment as provided herein.(g)

   No Change of Certificates: Irrespective of any adjustment or change in the Exercise Price or the number of Voting Shares issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price per Voting Share and the number of Voting Shares which were expressed in the initial Rights Certificates issued hereunder.(h)

  Timing of Issuance: In any case in which this Section 2.3 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Corporation may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Voting Shares and other securities of the


---

Corporation, if any, issuable upon such exercise over and above the number of Voting Shares and other securities of the Corporation, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; (i)

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

   consolidation or subdivision of Voting Shares;(ii)

   issuance (wholly or in part for cash) of Voting Shares or securities that by their terms are convertible into or exchangeable for Voting 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 Voting Shares, shall not be taxable to such shareholders. 2.4

   Date on Which Exercise is Effective
 Each Person in whose name any certificate for Voting 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 Voting 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 Subsection 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 transfer books of the Voting Shares of the Corporation are closed, such Person shall be deemed to have become the holder of record of such Voting Shares on, and such certificate shall be dated, the next succeeding Business Day on which the transfer books of the Voting Shares are open. 2.5

   Execution, Authentication, Delivery and Dating of Rights Certificates
  (a)

   Execution: The Rights Certificates shall be executed on behalf of the Corporation, under its corporate seal reproduced thereon, by any one of its Chairman, President, Chief Executive Officer or a Vice-President or Secretary. The signature of any of these officers on the Rights Certificates may be manual or facsimile.(b)

   Valid Signatures: 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.(c)

   Delivery: Promptly after the Corporation learns of the Separation Time, the Corporation shall notify the Rights Agent of such Separation Time and shall deliver Rights Certificates executed by the Corporation to the Rights Agent for countersignature, and the Rights Agent shall countersign (manually or by facsimile signature in a manner satisfactory to the Corporation) and send such Rights Certificates to the holders of the Rights pursuant to Subsection 2.2(c) hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent in the manner described above.(d)

  Date: Each Rights Certificate shall be dated the date of countersignature thereof.

2.6

   Registration, Transfer and Exchange
  (a)

   Maintaining of Register: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 shall provide for the registration and transfer of Rights. The Rights Agent is hereby appointed registrar for the Rights ("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. If the Rights Agent shall cease to be the Rights Registrar, the Rights Agent shall have the right to examine such register at all reasonable times. After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of Subsection 2.6(c) below, the Corporation shall execute, and the Rights Agent shall countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificate so surrendered.(b)

   Effect of Transfer or Exchange:All Rights issued upon any registration of a 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.(c)

   Transfer or Exchange of Rights: Every Rights Certificate surrendered for registration of transfer or exchange shall have the form of assignment thereon completed and executed, or be accompanied by a written instrument of transfer in form satisfactory to the Corporation or the Rights Agent, as the case may be, executed by the holder thereof or the attorney of such holder duly authorized in writing. As a condition to the issue of any new Rights Certificate under this Section 2.6, the Corporation may require the payment of an amount sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and other expenses, including the reasonable fees and expenses of its Rights Agent, connected therewith.(d)

  No Transfer or Exchange After Termination: The Corporation shall not be required to register the transfer or exchange of any Rights after the Rights have been terminated under Section 5.1(e) hereof.
  2.7

   Mutilated, Destroyed, Lost and Stolen Rights Certificates

   Mutilation: If there shall be delivered to the Corporation and the Rights Agent prior to the Expiration Time, evidence to their satisfaction of the mutilation or defacing of any Rights Certificate, the Corporation shall execute and the Rights Agent shall countersign and deliver a new Rights Certificate upon surrender and cancellation of the mutilated or defaced Rights Certificate.(b)

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

  Original Obligation: Every new Rights Certificate issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Rights Certificate shall evidence an additional original contractual obligation of the Corporation, whether or not the mutilated, 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 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 such Rights Certificate (or, prior to the Separation Time, the associated Voting Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby for all purposes whatsoever.

   prior to the Separation Time, each Right shall be transferable only together with, and shall be transferred by a transfer of, the associated Voting Share certificate representing such Right;(c)

   after the Separation Time, the Rights Certificates shall be transferable only on the Rights Register as provided herein;(d)

   prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the certificate evidencing the associated Voting 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 certificate evidencing the associated Voting 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 certificate evidencing the associated Voting Share 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)

   such holder has waived all rights to receive any fractional Right or any fractional Voting Shares or other securities upon exercise of a Right (except as provided herein); and(f)

  that, subject to the provisions of Section 5.4, without the approval of any holder of Rights or Voting Shares and upon the sole authority of the Board of Directors, acting in good faith, this Agreement may be supplemented or amended from time to time to cure any ambiguity or to


---

correct or supplement any provision contained herein which may be inconsistent with the intent of this Agreement or is otherwise defective, as provided herein. 2.11

   Rights Certificate Holder Not Deemed a Shareholder
 No holder, as such, of any Rights or Rights Certificate shall be entitled to vote, receive dividends or be deemed for any purpose whatsoever the holder of any Voting Share or any other share or security of the Corporation which may at any time be issuable on the exercise of the Rights represented thereby, nor shall anything contained herein or in any Rights Certificate be construed or deemed or confer upon the holder of any Right or Rights Certificate, as such, any right, title, benefit or privilege of a holder of Voting Shares or any other shares or securities of the Corporation or any right to vote at any meeting of shareholders of the Corporation whether for the election of directors or otherwise or upon any matter submitted to the holders of Voting Shares or any other shares of the Corporation at any meeting thereof, or to give or withhold consent to any action of the Corporation, or to receive notice of any meeting or other action affecting any holder of Voting Shares or any other shares of the Corporation except as expressly provided herein, or to receive dividends, distributions or subscription rights, or otherwise, until the Rights or Rights evidenced by the Rights Certificates shall have been duly exercised in accordance with the terms and the provisions hereof.

   a transferee of Rights, directly or indirectly, 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 an Affiliate or Associate of an Acquiring Person), where such transferee becomes a transferee concurrently with or subsequent to the Acquiring Person becoming such in a transfer that the Board of Directors has determined is part of a plan, arrangement or scheme of an Acquiring Person (or any affiliate or associate of an Acquiring Person or any person acting jointly or in concert with an Acquiring Person or any affiliate or associate of an Acquiring Person), that has the purpose or effect of avoiding Section 3.1(b)(i),shall become null and void without any further action and any holder of such Rights, including transferees, shall thereafter have no right to exercise such Rights under any provision of this Agreement and further shall thereafter not have any other rights whatsoever with respect to such Rights, whether under any provision of this Agreement or otherwise.

This Rights Certificate and the Rights represented hereby shall become void in the circumstances specified in Subsection 3.1(b) of the Shareholder Rights 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 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 on the Rights Certificate that such holder is not a Person described in such legend.
  3.2

   Exchange Option
  (a)

   Optional Exchange: In the event that the Board of Directors acting in good faith shall determine that conditions exist which would eliminate or otherwise materially diminish in any respect the benefits intended to be afforded to the holders of Rights pursuant to this Agreement, the Board of Directors may at its option and without seeking the approval of holders of Voting Shares or Rights at any time after a Flip-in Event has occurred, authorize the Corporation to issue and deliver in respect of each Right which is not void pursuant to Section 3.1(b) either:(i)

   in return for the Exercise Price and Right, cash, debt, equity or other securities or other property or assets (or a combination thereof) having a value equal to twice the Exercise Price; or(ii)

   in return for the Right and without further charge, subject to any amounts that may be required to be paid under applicable law, cash, debt, equity or other securities or other property or assets (or a combination thereof), having a value equal to the Exercise Price;in full and final settlement of all rights attaching to the Rights; provided that the value of any such debt, equity or other securities or other property or assets shall be determined by the Board of Directors who may rely for that purpose on the advice of a nationally recognized Canadian firm of investment dealers or investment bankers selected by the Board of Directors. To the extent that the Board of Directors determines in good faith that any action need be taken pursuant to this Section 3.2, the Board of Directors may suspend the exercisability of the Rights for a period up to 60 days following the date of the occurrence of the relevant Flip-in Event inorder to determine the appropriate form and value of cash, debt, equity or other securities or other property or assets (or a combination thereof) to be issued or delivered on such exchange for Rights. In the event of any such suspension, the Corporation shall notify the Rights Agent and issue as promptly as practicable a public announcement stating that the exercisability of the Rights has been temporarily suspended.(b)

  Termination of Right to Exercise: If the Board of Directors authorizes and directs the exchange of cash, debt, equity or other securities or other property or assets (or a combination thereof) for


---

Rights pursuant to Subsection 3.2(a) hereof, then without any further action or notice the right to exercise the Rights will terminate and the only right thereafter of a holder of Rights shall be to receive such cash, debt, equity or other securities or other property or assets (or a combination thereof) in accordance with the determination of the Board of Directors made pursuant to Section 3.2(a). Within 10 Business Days of the Board of Directors authorizing and directing any such exchange, the Corporation shall give notice of such exchange to the holders of such Rights in accordance with Section 5.9. Each such notice of exchange shall state the method by which the exchange of cash, debt, equity or other securities or other property or assets (or a combination thereof) for Rights will be effected. (c)

  Additional Securities: If there shall not be sufficient securities authorized but unissued to permit the exchange in full of Rights pursuant to this Section 3.2, the Corporation will take all such action as may be necessary to authorize additional securities for issuance upon the exchange of Rights provided however, that the Corporation shall not be required to issue fractions of securities or to distribute certificates evidencing fractional securities. In lieu of issuing such fractional securities, subject to Section 5.5(b), there shall be paid to the registered holders of Rights to whom such fractional securities would otherwise be issuable, an amount in cash equal to the same fraction of the market price of a whole such security.

   Change of Name: 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

   Legal Counsel: The Rights Agent may consult with legal counsel (who may be legal counsel for the Corporation), and the opinion of such counsel shall be full and complete authorization and protection to the Rights Agent as to any action taken or omitted to be taken by it in good faith and in accordance with such opinion.(b)

   Satisfactory Proof: 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 or omitting to take 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, the President, the Chief Executive Officer or any Vice-President and by the Chief Financial Officer, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant Secretary of the Corporation and delivered to the Rights Agent and such certificate shall be full authorization to the Rights Agent for any action taken, omitted or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate.(c)

   Bad Faith: The Rights Agent shall be liable hereunder only for its own negligence, bad faith or willful misconduct.(d)

   Recitals: The Rights Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the certificates representing Voting 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 only by the Corporation.(e)

   No Responsibility: The Rights Agent shall not be under any responsibility in respect of the validity of this Agreement or the execution and delivery hereof (except the authorization, execution and delivery hereof by the Rights Agent) or in respect of the validity or execution of


---

any certificate representing Voting Shares or Rights Certificate (except its countersignature thereof), nor will it be responsible for any breach by the Corporation of any covenant or condition contained in this Agreement or in any Rights Certificate, any change in the exercisability of the Rights (including the Rights becoming void pursuant to Section 2.11 or Subsection 3.2(b) hereof) or any adjustment required under the provisions of Section 2.3 hereof or for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Section 2.3 hereof describing any such adjustment) nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any Voting Shares to be issued pursuant to this Agreement or any Rights or as to whether any Voting Shares shall, when issued, be duly and validly authorized, executed, issued and delivered and be fully paid and non-assessable. (f)

   Performance By Corporation: 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)

   Persons To Give Instructions: The Rights Agent is hereby authorized to rely upon and directed to accept instructions in writing with respect to the performance of its duties hereunder from any person believed by the Rights Agent to be the Chairman, the President, the Chief Executive Officer, any Vice-President, the Secretary, any Assistant Secretary, the Chief Financial Officer, the Treasurer or any Assistant Treasurer of the Corporation and to apply to such persons for advice or instructions in connection with its duties, and it shall not be liable for any action taken, omitted or suffered by it in good faith in accordance with the instructions of any such person.(h)

Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity.(i)

   No Liability: 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 shall not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act, omission, 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 upon 60 days' notice (or such lesser notice as is acceptable to the Corporation) in writing delivered or mailed to the Corporation and to each transfer agent of Common Shares by first class or registered mail. The Corporation may remove the Rights Agent upon 60 days' notice in writing, mailed or delivered to the Rights Agent and to each transfer agent of Common Shares by first class or registered mail. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Corporation shall appoint a successor to the Rights Agent. If the Corporation 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 or by the holder of any Rights (which holder shall, with such notice, submit the Rights Certificate of such holder for inspection by 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, shall be a trust company incorporated under the laws of Canada or a province thereof authorized to carry on the business of a trust company as principal or through an agent in the Provinces of Ontario or British Columbia. After appointment, the successor Rights Agent shall 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; provided that the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Corporation shall file notice thereof in writing with the predecessor Rights Agent and the transfer agent of the Common Shares, and mail a notice thereof in writing to the holders of the Rights. 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 5MISCELLANEOUS 5.1

   Redemption and Waiver
  (a)

   The Board of Directors acting in good faith may, until the occurrence of a Flip-in Event, upon prior written notice delivered to the Rights Agent, determine to waive the application of Section 3.1 to such particular Flip-in Event (which for greater certainty shall not include the circumstances described in Subsection 5.1(h)); provided that if the Board of Directors waives the application of Section 3.1 to a particular Flip-in Event pursuant to this Subsection 5.1(a), the Board of Directors shall be deemed to have waived the application of Section 3.1 to any other Flip-in Event which may arise in respect of any Take-Over Bid then in effect or made prior to the public announcement of the completion or termination of the transaction in respect of which the Board of Directors waived the application of Section 3.1.(b)

   The Board of Directors acting in good faith may, at its option, at any time prior to the provisions of Section 3.1 becoming applicable as a result of the occurrence of a Flip-in Event, elect to redeem all but not less than all of the outstanding Rights at a redemption price of $0.0001 per Right appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 if an event of the type analogous to any of the events described in Section 2.3 shall have occurred (such redemption price being herein referred to as the "Redemption Price"). The redemption of the Rights by the Board of Directors may be made effective at such time, on such basis and with such conditions as the Board of Directors in its sole discretion may establish.(c)

   In the event that prior to the occurrence of a Flip-in Event a Person acquires, pursuant to a Permitted Bid or a Competing Permitted Bid, not less than 90% of the outstanding Voting Shares other than Voting Shares Beneficially Owned at the date of the Permitted Bid or the Competing Permitted Bid by such Person, then the Board of Directors of the Corporation shall immediately upon the consummation of such acquisition without further formality be deemed to have elected to redeem the Rights at the Redemption Price.(d)

   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.(e)

   If the Board of Directors is deemed under Subsection 5.1(c) to have elected, or elects under either of Subsection 5.1(b) or (d), to redeem the Rights, the right to exercise the Rights will thereupon, without further action and without notice, terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price.(f)

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

   Upon the Rights being redeemed pursuant to Subsection 5.1(d), all the provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder of record of Voting 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.(h)

   The Board of Directors may waive the application of Section 3.1 in respect of the occurrence of any Flip-in Event if the Board of Directors has determined within ten Trading Days following a Share Acquisition Date that a Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person under this Agreement and, in the event that such a waiver is granted by the Board of Directors, such Share Acquisition Date shall be deemed not to have occurred. Any such waiver pursuant to this Subsection 5.1(b) must be on the condition that such Person, within 14 days after the foregoing determination by the Board of Directors or such earlier or later date as the Board of Directors may determine (the "Disposition Date"), has reduced its Beneficial Ownership of Voting Shares such that the Person is no longer an Acquiring Person. If the Person remains an Acquiring Person at the close of business on the Disposition Date, the Disposition Date shall be deemed to be the date of occurrence of a further Share Acquisition Date and Section 3.1 shall apply thereto.
  5.2

   Expiration
 No Person shall have any rights pursuant to this Agreement or any Right after the Expiration Time, except as provided in Section 4.1 hereof. 5.3

   Issue of New Rights Certificates
 Notwithstanding any of the provisions of this Agreement or of the Rights to the contrary, the Corporation may, at its option, issue new Rights Certificates evidencing Rights in such form as may be approved by the Board of Directors to reflect any adjustment or change in the number or kind of securities purchasable upon exercise of Rights made in accordance with the provisions of this Agreement. 5.4

   Supplements and Amendments
  (a)

   The Corporation may make amendments to this Agreement to correct any clerical or typographical error or which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation or regulations thereunder. The Corporation may, prior to the date of the shareholders' meeting referred to in Section 5.16, supplement or amend this Agreement without the approval of any holders of Rights or Voting Shares in order to make any changes which the Board of Directors acting in good faith may deem necessary or desirable. Notwithstanding anything in this Section 5.4 to the contrary, no such supplement or amendment shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such supplement or amendment.(b)

   Subject to the Section 5.4(a), the Corporation may, with the prior consent of the holders of Voting Shares obtained as set forth below, at any time prior to the Separation Time, amend, vary or rescind any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally). Such consent shall be deemed to have been given if the action requiring such approval is authorized by the affirmative vote of a majority of the votes cast by Independent Shareholders present or represented at and entitled to be voted at a meeting of the holders of Voting Shares duly called and held in compliance with applicable laws and the constating documents of the Corporation.(c)

   The Corporation may, with the prior consent of the holders of Rights, at any time on or after the Share Acquisition Date, vary or delete any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of the holders of Rights generally), provided that no such amendment, variation or deletion shall be made to the


---

provisions of Article 4 except with the written concurrence of the Rights Agent thereto. Such consent shall be deemed to have been given if such amendment, variation or deletion is authorized by the affirmative votes of the holders of Rights present or represented at and entitled to be voted at a meeting of the holders and representing 50% plus one of the votes cast in respect thereof. (d)

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

   Any amendments made by the Corporation to this Agreement pursuant to Subsection 5.4(a) which are required to maintain the validity of this Agreement as a result of any change in any applicable legislation or regulation thereunder shall:(i)

   if made before the Separation Time, be submitted to the shareholders of the Corporation at the next meeting of shareholders and the shareholders may, by the majority referred to in Subsection 5.4(b), confirm or reject such amendment;(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 Corporation and the holders of Rights may, by resolution passed by the majority referred to in Subsection 5.4(c), 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. 5.5

   Fractional Rights and Fractional Voting Shares
  (a)

   No Fractional Rights: The Corporation shall not be required to issue fractions of Rights or to distribute Right Certificates which evidence fractional Rights. After the Separation Time, in lieu of issuing fractional Rights the Corporation shall pay to the holders of record of the Right Certificates, at the time such fractional Rights would otherwise be issuable, an amount in cash equal to the same fraction of the Market Price of one whole Right that the fraction of a Right that would otherwise be issuable is of one whole Right.(b)

   No Fractional Common Shares:The Corporation shall not be required to issue fractions of Voting Shares upon exercise of the Rights or to distribute certificates which evidence fractional Voting Shares. In lieu of issuing fractional Voting Shares, the Corporation shall pay to the holders of record of Right Certificates at the time such Rights are exercised as herein provided, an amount in cash equal to the same fraction of the Market Price of one Voting Share that the fraction of a Voting Share that would otherwise be issuable upon the exercise of such Right is of a whole Voting Share.
  5.6

   Rights of Action
 Subject to the terms of this Agreement, 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, and any holder of any 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 Corporation to enforce, or otherwise act in respect of, such holder's right to exercise the Rights of such holder in the manner provided in the Rights Certificate of such holder and in this Agreement.
