THE RIGHTS

2.1 Legend on Common Share Certificates

     (a) Certificates issued for Common Shares, including without limitation Common Shares issued upon the conversion of Convertible Securities, after the Record Time but prior to the close of business on the earlier of the Separation Time and the Expiration Time shall evidence one Right for each Common Share represented thereby and shall have impressed on, printed on, written on or otherwise affixed to them a legend in substantially the following form:

Until the Separation Time (as defined in the Rights Agreement referred to below), this certificate also evidences and entitles the holder hereof to certain Rights as set forth in the Shareholder Rights Plan Agreement dated as of the 6th day of September, 2012, as amended from time to time (the "Rights Agreement"), between Pacific Rim Mining Corp. (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 offices of the Company. Under certain circumstances, as set forth in the Rights Agreement, such Rights may be amended, redeemed, may expire, may become null and void (if, in certain cases, they are "Beneficially Owned" by an "Acquiring Person", as such terms are defined in the Rights Agreement, or a transferee thereof) or may be evidenced by separate certificates and may no longer be evidenced by this certificate. The Company will mail or arrange for the mailing of a copy of the Rights Agreement to the holder of this certificate without charge as soon as is reasonably practicable after the receipt of a written request therefor.

- 20 -

Certificates representing Common Shares that are issued and outstanding as at the Record Time shall evidence one Right for each Common Share evidenced thereby notwithstanding the absence of the foregoing legend until the earlier of the Separation Time and the Expiration Time.

     (b) Registered holders of Common Shares who have not received a share certificate and are entitled to do so on the earlier of the Separation Time and the Expiration Time shall be entitled to Rights as if such certificates had been issued and such Rights shall for all purposes hereof be evidenced by the corresponding entries on the Company's securities registers for the Common Shares.

2.2 Initial Exercise Price, Exercise of Rights and Detachment of Rights

     (a) Subject to adjustment as provided herein, each Right will entitle the Holder thereof, after the Separation Time and prior to the Expiration Time, to purchase, for the Exercise Price as at the Business Day immediately preceding the date of exercise of the Right, one Common Share (which Exercise Price and number of Common Shares are subject to adjustment as set forth herein). Notwithstanding any other provision of this Agreement, any Rights Beneficially Owned 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) for administrative purposes, each Right will be evidenced by the certificates for the associated Common Share registered in the name of the holder thereof (which certificate shall also be deemed to be a Rights Certificate) and will be transferable only together with, and will be transferred by a transfer of, such associated Common Share.

     (c) From and after the Separation Time and prior to the Expiration Time, the Rights shall be exercisable and the registration and transfer of the Rights shall be separate from and independent of the Common Shares. 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 and, in respect of each Convertible Security converted into or exchanged or exercised for Common Shares after the Separation Time and prior to the Expiration Time, promptly after such conversion, exchange or exercise to the holder so converting, exchanging or exercising (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 on the records of the Company (the Company hereby agreeing to furnish copies of such records to the Rights Agent for this purpose),

  (i)

a certificate (a "Rights Certificate") in substantially the form of Exhibit A hereto appropriately completed, representing the number of Rights held by such Holder at the Separation Time and having such marks of identification or designation and such legends, summaries or endorsements printed thereon as the 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, regulation or judicial or administrative order or with any rule or regulation made pursuant thereto 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 admitted to trading, or to conform to standard usage; and


- 21 -

  (ii)

a disclosure statement prepared by or on behalf of the Company describing the Rights;

provided that a Nominee shall be sent the materials provided for in Clauses 2.2(c)(i) and (ii) in respect of all Common Shares held of record by it which are not Beneficially Owned by an Acquiring Person. In order for the Company to determine whether any Person is holding Common Shares which are Beneficially Owned by another Person, the Company may require such first mentioned Person to furnish it with such information and documentation as the Company considers advisable.

     (d) Rights may be exercised in whole or in part on any Business Day after the Separation Time and prior to the Expiration Time by submitting to the Rights Agent, at its principal office in the city of Vancouver or any other office of the Rights Agent or Co-Rights Agent in the cities designated from time to time for that purpose by the Company with the approval of 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 duly 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 or to the order of the Rights Agent, of a sum equal to the Exercise Price multiplied by the number of Rights being exercised and a sum sufficient to cover any transfer tax or charge which may be payable in respect of 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, accompanied by an Election to Exercise appropriately completed and duly exercised that does not indicate that such Right is null and void as provided by Subsection 3.1(b) and by payment as set forth in Clause 2.2(d)(iii), the Rights Agent (unless otherwise instructed in writing by the Company in the event that the Company is of the opinion that the Rights cannot by exercised in accordance with this Agreement) will thereupon promptly:

- 22 -

 

(i)

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

 

 

  
 

(ii)

after receipt of any certificates referred to in Clause 2.2(e)(i), deliver such certificates to or upon the order of the registered holder of such Rights Certificate, registered in such name or names as may be designated by such holder;

 

 

  
 

(iii)

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

 

 

  
 

(iv)

when appropriate, after receipt, deliver such cash (less any amounts required to be withheld) to or to the order of the registered holder of the Rights Certificate; and

 

 

  
 

(v)

tender to the Company all payments received on 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 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 shares (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered and 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 Business Corporations Act, the Securities Act (BC), the 1933 Securities Act, the 1934 Exchange Act and the comparable securities 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)

on or before the issuance thereof, use reasonable efforts to cause all Common Shares issued upon exercise of Rights to be listed or admitted to trading upon issuance on the principal exchange or exchanges on which the Common Shares are then listed or admitted to trading at that time;

 

 

  

(iv)

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


- 23 -

  (v)

pay when due and payable any and all Canadian and United States federal, provincial and state transfer taxes (not including any tax in the nature of income or capital gains taxes of the Holder or exercising Holder or any liability of the Company to withhold tax) and charges which may be payable in respect of the original issuance or delivery of the Rights Certificates or certificates for Common Shares or registration of the Common Shares in the securities register of the Company, provided that the Company shall not be required to pay any transfer tax or charge which may be payable in respect of the transfer or delivery of Rights Certificates or the issuance or delivery of certificates for Common Shares or registration of the Common Shares in the securities register of the Company in a name other than that of the Holder of the Rights being transferred or exercised.


2.3 Adjustments to Exercise Price; Number of Rights

     (a) The Exercise Price, the number and kind of securities subject to purchase upon exercise of each Right and the number of Rights outstanding are subject to adjustment from time to time as provided in this Section 2.3 and in Subsection 3.1(a).

     (b) 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 Convertible Securities other than pursuant to any regular dividend reinvestment plan of the Company providing for the acquisition of Common Shares;

 

 

  
 

(ii)

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

 

 

  
 

(iii)

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

 

 

  
 

(iv)

issue any Common Shares, Convertible Securities or other capital stock of the Company in respect of, in lieu of or in exchange for existing Common Shares except as otherwise provided in this Section 2.3;

the Exercise Price in effect at the time of the record date for such dividend or of the effective date of such subdivision, combination or other change, and the number of Common Shares or other securities, as the case may be, issuable on such date, shall be proportionately adjusted so that the holder of any Right shall be entitled to receive, upon payment of the applicable Exercise Price then in effect, the aggregate number of Common Shares or other securities, as the case may be, which, if such Right had been exercised immediately prior to such date and at a time when the share transfer books of the Company were open, such holder would have been entitled to receive as a result of such dividend, subdivision, combination or reclassification.

- 24 -

     (c) In the event the Company shall at any time after the Record Time and prior to the Expiration Time fix a record date for the issuance of rights, options or warrants to all holders of Common Shares entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares, shares having the same rights, privileges, restrictions and conditions as Common Shares ("equivalent common shares"), or securities convertible into or exchangeable for or carrying a right to purchase Common Shares or equivalent common shares at a price per Common Share or per equivalent common share (or, if a security convertible into or exchangeable for or carrying a right to purchase or subscribe for Common Shares or equivalent 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 90% of the Market Price per Common Share on the second Trading Day immediately preceding 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 and/or equivalent common shares so to be offered (and/or the aggregate initial conversion, exchange or exercise price of the convertible or exchangeable securities or rights so to be offered, including the price required to be paid to purchase such convertible or exchangeable securities or rights) 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 and/or equivalent 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 have been 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, equivalent 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.

- 25 -

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

     (d) In the event the Company shall at any time after the Record Time and prior to the Expiration Time fix a record date for the making of a distribution to all holders of Common Shares (including any such distribution made in connection with a merger in which the Company is the continuing corporation or amalgamation) of evidences of indebtedness or assets, including cash (other than a regular periodic cash dividend or a dividend paid in Common Shares, but including any dividend payable in securities other than Common Shares), subscription rights, options or warrants (excluding those referred to in Subsection 2.3(c)) hereof at a price per Common Share that is less than 90% of the Market Price per Common Share on the second Trading Day immediately preceding such record date, the Exercise Price in respect of the Rights to be in effect after such record date shall be determined by multiplying the Exercise Price in respect of the Rights in effect immediately prior to such record date by a fraction:

  (i)

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

     
  (ii)

the denominator of which shall be such Market Price per Common Share.

Such adjustments shall be made successively whenever such a record date is fixed, and in the event that such a distribution is not so made, the Exercise Price shall be readjusted to be the Exercise Price which would have been in effect if such record date had not been fixed.

     (e) 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 Subsection 2.3(e) are not required to be made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 2.3 shall be made to the nearest cent or to the nearest ten-thousandth of a Common Share or Right. Notwithstanding the first sentence of this Subsection 2.3(e), any adjustment required by this Section 2.3 shall be made no later than the Expiration Time.

     (f) In the event the Company shall at any time after the Record Time and prior to the Expiration 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(b)(i) or (iv), if the Board of Directors acting in good faith determines that the adjustments contemplated by Subsection 2.3(b) in connection with such transaction will not appropriately protect the interests of the Holders of Rights, the Board of Directors acting in good faith 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 Subsection 2.3(b), such adjustments, rather than the adjustments contemplated by Subsection 2.3(b), shall be made. The Company and the Rights Agent shall have authority with the prior approval of the holders of the Common Shares or the Holders of Rights to amend this Agreement in accordance with Section 5.5 hereof, as appropriate to provide for such adjustments.

     (g) Unless the Company shall have exercised its election as provided in Subsection 2.3(h), upon each adjustment of an Exercise Price as a result of the calculations made in Subsections 2.3(c), (d) and (f), each Right outstanding immediately prior to the making of such adjustment shall thereafter evidence the right to purchase, at the adjusted Exercise Price, that number of Common Shares, as the case may be (calculated to the nearest one ten-thousandth), obtained by:

  (i)

multiplying:

       
  (A)

the number of such Common Shares which would have been issuable upon the exercise of a Right immediately prior to this adjustment; by

       
  (B)

the relevant Exercise Price in effect immediately prior to such adjustment of the relevant Exercise Price; and

       
  (ii)

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

     (h) The Company may elect on or after the date of any adjustment of an Exercise Price to adjust the number of Rights, in lieu of any adjustment in the number of Common Shares purchasable upon the exercise of a Right. Each of the Rights outstanding after the adjustment in the number of Rights shall be exercisable for the number of Common Shares for which such a Right was exercisable immediately prior to such adjustment. Each Right held of record prior to such adjustment of the number of Rights shall become that number of Rights (calculated to the nearest one ten-thousandth) obtained by dividing the relevant Exercise Price in effect immediately prior to adjustment of the relevant Exercise Price by the relevant Exercise Price in effect immediately after adjustment of the relevant Exercise Price. The Company shall make a public announcement of its election to adjust the number of Rights, indicating the record date for the adjustment, and, if known at the time, the amount of the adjustment to be made. This record date may be the date on which the relevant Exercise Price is adjusted or any day thereafter, but, if the Rights Certificates have been issued, shall be at least 10 days later than the date of the public announcement. If Rights Certificates have been issued, upon each adjustment of the number of Rights pursuant to this Subsection 2.3(h), the Company shall, as promptly as is practicable, cause to be distributed to holders of record of Rights Certificates on such record date, Rights Certificates evidencing, subject to Section 5.6, the additional Rights to which such holders shall be entitled as a result of such adjustment, or, at the option of the Company, shall cause to be distributed to such holders of record in substitution and replacement for the Rights Certificates held by such holders prior to the date of adjustment, and upon surrender thereof, if required by the Company, new Rights Certificates evidencing all the Rights to which such holders shall be entitled after such adjustment. Rights Certificates to be so distributed shall be issued, executed and countersigned in the manner provided for herein and may bear, at the option of the Company, the relevant adjusted Exercise Price and shall be registered in the names of holders of record of Rights Certificates on the record date specified in the public announcement.

- 27 -

     (i) 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.

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

     (k) 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 Certificate 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.

     (l) 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 Company may elect to defer until the occurrence of such event the issuance to the Holder of any Right exercised after such record date of the number of Common Shares and other securities of the 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 a due xxxx or other appropriate instrument evidencing such Holder's right to receive such additional Common Shares (fractional or otherwise) or other securities upon the occurrence of the event requiring such adjustment.

     (m) Notwithstanding anything in this Section 2.3 to the contrary, the Company shall be entitled to make such reductions in each Exercise Price, in addition to those adjustments expressly required by this Section 2.3, as and to the extent that in its good faith judgment the Board of Directors shall determine to be advisable in order that any: (i) consolidation or subdivision of Common Shares; (ii) issuance wholly for cash of any Common Share or Convertible Securities; (iii) stock dividends; or (iv) issuance of rights, options or warrants referred to in this Section 2.3, hereafter made by the Company to holders of its Common Shares, shall not be taxable to such shareholders.

- 28 -

     (n) The Company covenants and agrees that, after the Separation Time, it will not, except as permitted by Sections 5.1, 5.2 and 5.5, take (or permit any Subsidiary of the Company 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.

     (o) Whenever an adjustment to the Exercise Price or a change in the securities purchasable upon exercise of the Rights is made at any time after the Separation Time pursuant to this Section 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)

file with the Rights Agent and with the transfer agent for the Common Shares a certificate specifying the particulars of such adjustment or change; and

     
  (ii)

give, or cause the Rights Agent to give, notice of the particulars of such adjustment or change to Holders of the Rights who request a copy;

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

2.4 Date on Which Exercise is Effective

     Each Person in whose name any certificate for Common Shares is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Shares represented thereby on, and such certificate shall be dated, the date upon which the Rights Certificate evidencing such Rights was duly surrendered (together with a duly completed Election to Exercise) and payment of the Exercise Price for such Rights (and any applicable transfer taxes and other governmental charges payable by the exercising 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.

2.5 Execution, Authentication, Delivery and Dating of Right Certificates

     (a) The Rights Certificates shall be executed on behalf of the Company by any two of its Chairman, its President and Chief Executive Officer, a Vice-President or any director, provided that at the time of such execution none of such officer or director, any Affiliate or Associate of such officer or director or any person with whom such officer or director or any such Affiliate or Associate is acting jointly or in concert has commenced or publicly announced an intention to commence a Take-over Bid. 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 prior to the countersignature and delivery of such Rights Certificates.

- 29 -

     (b) Promptly after the Company learns of the Separation Time, the Company will notify the Rights Agent in writing 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 Subsection 2.2(c) hereof. No Rights Certificate shall be valid for any purpose until countersigned by the Rights Agent as aforesaid.

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

2.6 Registration, Registration of Transfer and Exchange

     (a) After the Separation Time, 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 "Rights Registrar" for the purpose of maintaining the Rights Register for the Company and registering Rights and transfers of Rights as herein provided. In the event that the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times.

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) and the other provisions of this Agreement, the Company will execute, and the Rights Agent will countersign and deliver, in the name of the Holder or the designated transferee or transferees as required pursuant to the Holder's instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificates so surrendered.

     (b) All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be 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 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. As a condition to the issuance of any new Rights Certificate under this Section 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 fees and expenses of the Rights Agent) connected therewith.

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

- 30 -

2.7 Mutilated, Destroyed, Lost and Stolen Rights Certificates

     (a) If any mutilated Rights Certificate is surrendered to the Rights Agent prior to the Expiration Time, the Company shall execute and the Rights Agent shall countersign and deliver in exchange therefor a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so surrendered.

     (b) If there shall be delivered to the 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 required by each of them in their sole discretion 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 its request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen.

     (c) As a condition to the issuance of any new Rights Certificate under this Section 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 fees and expenses of the Rights Agent) connected therewith.

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

2.8 Persons Deemed Owners

     Prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) for registration of 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 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 and the Company and the Rights Agent shall not be affected by any notice or knowledge to the contrary except as required by statute or by order of a court of competent jurisdiction.

2.9 Delivery and Cancellation of Certificates

     All Rights Certificates surrendered upon exercise or for redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Rights Agent, be delivered to the Rights Agent and, in any case, shall be promptly cancelled by the Rights Agent. The 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 Section 2.9, except as expressly permitted by this Agreement. The Rights Agent shall destroy all cancelled Rights Certificates and deliver a certificate of destruction to the Company on request by the Company.

- 31 -

2.10 Agreement of Rights Holders

     Every Holder of Rights, by accepting such Rights, becomes a party to this Agreement and for greater certainty is bound by the provisions herein and consents and agrees with the Company and the Rights Agent and with every other Holder of Rights that:

  (a)

such holder shall 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)

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)

after the Separation Time, the Rights Certificates will 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 associated Common Share certificate) for registration of transfer or exchange, 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)

such holder is not entitled and has waived his right to receive any fractional Rights or any fractional Common Shares upon exercise of a Right (except as provided herein);

     
  (f)

subject to the provisions of Section 5.5, without the approval of any Holder of Rights and upon the sole authority of the Board of Directors acting in good faith, this Agreement may be supplemented or amended from time to time pursuant to and as provided herein; and

     
  (g)

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 or any other Person as a result of its inability to perform any of its obligations under this Agreement by reason of a preliminary or permanent injunction or other order, decree or ruling issued by a court of competent jurisdiction or by a governmental, regulatory or administrative agency or commission, or any statute, rule, regulation or executive order promulgated or enacted by any governmental authority, prohibiting or otherwise restraining performance of such obligation.


- 32 -

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 to be 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 to confer upon the Holder of any Right or Rights Certificate, as such, any of the rights, title, benefits or privileges 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 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 or securities of the Company except as expressly provided herein, or to receive dividends, distributions or subscription rights, or otherwise, until such Rights shall have been duly exercised in accordance with the terms and provisions hereof.

ARTICLE 3

ADJUSTMENTS TO THE RIGHTS ON FLIP-IN EVENT

3.1 Flip-in Event

     (a) Subject to the provisions of Section 2.2, Subsection 3.1(b) and Section 5.2, in the event that prior to the Expiration Time a Flip-in Event shall occur, each Right shall constitute, effective from and after the later of its date of issue and 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 twice the Exercise Price for an amount in cash equal to the Exercise Price (such right to be appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3, without duplication, in the event that after such date of consummation or occurrence, an event of a type analogous to any of the events described in Section 2.3 shall have occurred with respect to such Common Shares).

     (b) Notwithstanding anything in this Agreement to the contrary, upon the occurrence of a 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 an Affiliate or Associate of an Acquiring Person); or

     
  (ii)

a transferee or other successor in title, direct or indirect, of Rights held by an Acquiring Person (or any Affiliate or Associate of an Acquiring Person or any Person acting jointly or in concert with an Acquiring Person or an Affiliate or Associate of an Acquiring Person), whether or not for consideration, in a transfer that the Board of Directors acting in good faith has determined is part of a plan, arrangement, understanding 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 an Affiliate or Associate of an Acquiring Person), that has the purpose or effect of avoiding Clause 3.1(b)(i);


- 33 -

shall become null and void without any further action, and any Holder of such Rights (including transferees or other successor in title) 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 of transfer or exchange which does not contain the necessary certifications set forth in the Rights Certificate establishing that such Rights are not void under this Subsection 3.1(b) shall be deemed to be an Acquiring Person for the purposes of this Subsection 3.1(b) and such rights shall be 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 this Section 3.1, including without limitation, all such acts and things as may be required to satisfy the requirements of the Business Corporations Act, the Securities Act (BC) and the securities laws or comparable legislation of each of the provinces of Canada and of the United States and each of the states thereof 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 Clause 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 Beneficially Owned by a Person who was an Acquiring Person or who was an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Rights Agreement) or was acting jointly or in concert with any of them. This Rights Certificate and the Rights represented hereby are void or shall become void in the circumstances specified in Subsection 3.1(b) of the 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 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 Subsection 3.1(d) shall be of no effect on the provisions of Subsection 3.1(b).

- 34 -

3.2 Exchange Option

     (a) The Board of Directors may, at its sole option and without seeking the approval of holders of Voting Shares or Rights but with the prior written consent of the Exchange if the Common Shares are then listed on such exchange, at any time after a Flip-in Event has occurred, authorize the Company to issue or deliver in respect of each Right which is not void pursuant to Subsection 3.1(b), either: (i) in return for the applicable Exercise Price and the Right, debt, equity or other securities or assets (or a combination thereof) having a value equal to twice the applicable Exercise Price; or (ii) in return for the Right, subject to any amounts that may be required to be paid under applicable law, debt, equity or other securities or assets (or a combination thereof) having a value equal to the value of the Right, in full and final settlement of all rights attaching to the Rights, where in either case the value of such debt, equity or other securities or other assets (or a combination thereof) and, in the case of Clause 3.2(a)(ii), the value of the Right, shall be determined by the Board of Directors which may rely upon the advice of a nationally or internationally recognized firm of investment dealers or investment bankers selected by the Board of Directors.

     (b) If the Board of Directors authorizes the exchange of debt or equity securities or assets (or a combination thereof) for Rights pursuant to Subsection 3.2(a), 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 the debt or equity securities or assets (or a combination thereof) in accordance with the exchange formula authorized by the Board of Directors. Within 10 Business Days after the Board of Directors has authorized the exchange of debt or equity securities or assets (or a combination thereof) for Rights pursuant to Subsection 3.2(a), the Company shall give notice of exchange to the holders of such Rights by mailing such notice to all such holders at their last addresses as they appear upon the register of Rights holders maintained by the Rights Agent. Each such notice of exchange will state the method by which the exchange of debt or equity securities or assets (or a combination thereof) for Rights will be effected.

ARTICLE 4

THE RIGHTS AGENT

4.1 General

     (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 one or more co-rights agents ("Co-Rights Agents") as it may deem necessary or desirable, subject to the prior written 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 written approval the Rights Agent and the Co-Rights Agents. 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 other disbursements incurred in the administration and execution of this Agreement and the exercise and performance of its duties hereunder (including the reasonable fees and disbursements of any expert or advisor retained by the Rights Agent with the prior approval of the Company). The Company also agrees to indemnify the Rights Agent and its directors, officers, employees and agents for, and to hold them harmless against, any loss, liability, or expense, incurred without gross negligence, bad faith or wilful misconduct on the part of the Rights Agent, for anything done, suffered or omitted by the Rights Agent in connection with the acceptance, execution and administration of this Agreement and the exercise and performance of its duties hereunder, including the costs and expenses of defending against any claim of liability, which right to indemnification will survive the termination of this Agreement on the resignation or removal of the Rights Agent.

- 35 -

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

     (c) The Company will 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 with respect to the then current directors and 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.

4.2 Merger or Amalgamation or Change of Name of Rights Agent

     (a) Any corporation into which the Rights Agent or any successor Rights Agent may be merged or amalgamated or with which it may be consolidated, or any corporation resulting from any merger, amalgamation, statutory arrangement or consolidation to which the Rights Agent or any successor Rights Agent is a party, or any corporation succeeding to the shareholder or stockholder services business of the Rights Agent or any successor Rights Agent, will be the successor to the Rights Agent under this Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto, provided that such corporation would be eligible for appointment as a successor Rights Agent under the provisions of Section 4.4 hereof. In case at the time such successor Rights Agent succeeds to the agency created by this Agreement any of the Rights Certificates have been countersigned but not delivered, any such successor Rights Agent may adopt the countersignature of the predecessor Rights Agent and deliver such Rights Certificates so countersigned; and in case at that time any of the Rights Certificates have not been countersigned, any successor Rights Agent may countersign such Rights Certificates either in the name of the predecessor Rights Agent or in the name of the successor Rights Agent; and in all such cases such Rights Certificates will have the full force provided in the Rights Certificates and in this Agreement.

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

- 36 -

4.3 Duties of Rights Agent

     The Rights Agent undertakes the duties and obligations imposed by this Agreement upon the following terms and conditions, by all of which the Company and the Holders of Rights Certificates, by their acceptance thereof, shall be bound.

  (a)

The Rights Agent may retain and consult with legal counsel (who may be legal counsel for the 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; the Rights Agent may also, with the approval of the Company (where such approval may reasonably be obtained and such approval not be unreasonably withheld), retain and consult with such other experts or advisors as the Rights Agent shall consider necessary or appropriate to properly carry out the duties and obligations imposed under this Agreement (at the Company's expense) and the Rights Agent shall be entitled to act and rely in good faith on the advice of any such expert or advisor.

     
  (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, the President and Chief Executive Officer, a Vice-President or a director 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 only for its own gross negligence, bad faith or wilful misconduct.

     
  (d)

The Rights Agent will not be liable for or by reason of any of the statements of fact or recitals contained in this Agreement or in the certificates for Common Shares or the Rights Certificates (except its countersignature thereof) or be required to verify the same, 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 Common Share certificate 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 exercisability of the Rights (including the Rights becoming void pursuant to Subsection 3.1(b) hereof) or any adjustment required under the provisions of Section 2.3 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment (except with respect to the exercise of Rights after receipt of the certificate contemplated by Clause 2.3(o)(i) hereof describing any such adjustment); nor will it by any act hereunder be deemed to make any representation or warranty as to the authorization of any Common Shares to be issued pursuant to this Agreement or any Rights or as to whether any Common Shares will, when issued, be duly and validly authorized, executed, issued and delivered and fully paid and non-assessable.


- 37 -

  (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 with respect to the performance of its duties hereunder from any person believed by the Rights Agent to be the Chairman, the President and Chief Executive Officer, a Vice-President or a director of the Company, and to apply to such persons for advice or instructions in connection with its duties, and it shall not be liable for any action taken or suffered by it in good faith in accordance with instructions of any such person. All such instruction shall, except where circumstances make it impracticable or the Rights Agent otherwise agrees, be given in writing and, where not in writing, such instructions will be confirmed in writing as soon as is reasonably practicable after the giving of such instructions.

     
  (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 become pecuniarily interested 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.

     
  (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 good faith 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 Company) in writing mailed to the Company and to the transfer agent of Common Shares by registered mail, and to the Holders of the Rights in accordance with Section 5.9 at the Company's expense. The Company may remove the Rights Agent upon 60 days' notice in writing, mailed to the Rights Agent and to the transfer agent of the Common Shares by registered mail, and to the Holders of the Rights in accordance with Section 5.9. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Company will appoint a successor to the Rights Agent. If the Company fails to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent or by the Holder of any Rights (which Holder shall, with such notice, submit such Holder's Rights Certificate for inspection by the Company), then the outgoing Rights Agent or Holder of any Rights may apply to any court of competent jurisdiction for the appointment of a new Rights Agent at the Company's expense. 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 carry on the business of a trust company in the Provinces of British Columbia and Ontario. After appointment, the successor Rights Agent will be vested with the same powers, rights, duties and responsibilities as if it had been originally named as Rights Agent without further act or deed; but the predecessor Rights Agent, upon payment by the Company to the predecessor Rights Agent of all outstanding fees and expenses, owed by the Company to the predecessor Rights Agent pursuant to this Agreement, 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 the transfer agent of the Common Shares, and mail or cause to be mailed 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.

4.5 Compliance with Money Laundering Legislation

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

- 39 -

4.6 Privacy Provision

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

MISCELLANEOUS

5.1 Redemption of Rights

     (a) Redemption of Holders of Voting Shares

     Until the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to Section 5.2 and provided that the provisions of Subsection 5.2(c) are not applicable to such Flip-in Event, the Board of Directors may elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $0.00001 per Right, appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 if an event of a type analogous to any of the events described in Section 2.3 shall have occurred (such redemption price being herein referred to as the "Redemption Price").

     (b) Deemed Redemption

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

     (c) Redemption on Withdrawal or Termination of Bid

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

- 40 -

     (d) Effect of Redemption

     If the Board of Directors elects or is deemed to have elected to redeem the Rights, (i) the right to exercise the Rights will thereupon, without further action and without notice, terminate and the only right thereafter of the holders of Rights shall be to receive the Redemption Price; and (ii) subject to Subsection 5.1(f) no further Rights shall be issued.

     (e) Notice of Redemption

     Within ten Business Days after the Board of Directors electing or having been deemed to have elected to redeem the Rights, the Company shall give notice of redemption to the Holders of the then outstanding Rights by mailing such notice to all such Holders at their last address as they appear upon the Rights Register or, prior to the Separation Time, on the share register maintained by the Company’s transfer agent or transfer agents for the Common Shares. Any notice which is mailed in the manner herein provided shall be deemed given, whether or not the Holder receives the notice. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made and will state that no payment will be made to holders entitled to less than $10.00 in accordance with Subsection 5.1(g). The Company may not redeem, acquire or purchase for value any Rights at any time in any manner other than that specifically set forth in this Section 5.1, except in connection with the purchase of Common Shares prior to the Separation Time.

     (f) Reissuance of Rights

     Upon the Rights being redeemed pursuant to this Section 5.1, Rights may be reissued under this Agreement to holders of record of Common Shares immediately following such redemption, and thereafter, all the provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder of record of Common Shares as of the Separation Time had not been mailed to each such holder and for all purposes of this Agreement, the Separation Time shall be deemed not to have occurred and such reissued Rights shall, without any further formality, be attached to the outstanding Common Shares in the same manner as prior to the occurrence of such Separation Time.

     (g) Redemption Price of Under $10

     The Company shall not be obligated to make a payment of the Redemption Price to any holder of Rights unless such holder is entitled to receive at least $10.00 in respect of all of the Rights held by such holder.

5.2 Waiver of Flip-In Event

     (a) Subject to the provisions of Subsection 5.2(d), the Board of Directors may, at any time prior to the occurrence of a Flip-in Event as to which the application of Section 3.1 has not been waived pursuant to this Section 5.2, waive the application of Section 3.1 to such Flip-in Event by written notice delivered to the Rights Agent.

- 41 -

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

  (i)

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

     
  (ii)

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

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

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

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

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