The Corporation will mail or arrange for the mailing of a copy of the Rights Agreement to the holder of this certificate without charge as soon as practicable after the receipt of a written request therefor.


- 16 -

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

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

(a)

Subject to adjustment as herein set forth, each Right will entitle the holder thereof, from and after the Separation Time and prior to the Expiration Time, to purchase, for the Exercise Price, one Common Share. Notwithstanding any other provision of this Agreement, any Rights held by the Corporation or any of its Subsidiaries shall be void.

     
(b)

Until the Separation Time:

     
(i)

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

     
(ii)

each Right will be evidenced by the certificate for the associated Common Share and will be transferable only together with, and will be transferred by a transfer of, such associated Common Share.

     
(c)

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

     
(i)

the Rights shall be exercisable; and

     
(ii)

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

     

Promptly following the Separation Time, the Corporation will prepare and the Rights Agent will mail or arrange to be mailed to each holder of record of Rights as of the Separation Time (other than an Acquiring Person and, in respect of any Rights Beneficially Owned by such Acquiring Person which are not held of record by such Acquiring Person, the holder of record of such Rights (a "Nominee")), at such holder's address as shown by the records of the Corporation (the Corporation hereby agreeing to furnish copies of such records to the Rights Agent for this purpose):


  (A)

a rights certificate ("Rights Certificate") representing the number of Rights held by such holder at the Separation Time and having such markers 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, regulation or judicial or administrative order or with any rule or regulation of any self-regulatory organization, stock exchange or quotation system on which the Rights may from time to time be listed or traded, or to conform to usage; and

     
  (B)

a disclosure statement describing the Rights;

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

- 17 -

(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 Calgary the Rights Certificate evidencing such Rights together with:

     
(i)

an election to exercise such Rights (an "Election to Exercise") substantially in the form attached to the Rights Certificate duly completed and executed by the holder or his executors or administrators or other personal representatives or his or their legal attorney duly appointed by an instrument in writing in form and executed in a manner satisfactory to the Rights Agent; and

     
(ii)

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

     
(e)

Upon receipt of a Rights Certificate, which is accompanied by a completed Election to Exercise that does not indicate that such Right is null and void as provided by subsection 3.1(b) and payment as set forth in subsection 2.2(d), the Rights Agent (unless otherwise instructed by the Corporation if 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 for the Common Shares certificates representing the number of such Common Shares to be purchased (the Corporation hereby irrevocably authorizing its transfer agent to comply with all such requisitions),

     
(ii)

after receipt of such certificate, deliver the same 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)

(g)

The Corporation covenants and agrees that it will:

     
(i)

take all such action as may be necessary and within its power to ensure that all securities delivered upon exercise of Rights shall, at the time of delivery of the certificates for such securities (subject to payment of the Exercise Price), be duly and validly authorized, executed, issued and delivered as fully paid and non-assessable;

take all such action as may be necessary and within its power to comply with any applicable requirements of Business Corporations Act (Alberta), the Securities Act (Alberta), the Securities Act (Ontario) and any other applicable laws in connection with the issuance and delivery of the Rights, the Rights Certificates and the issuance of any securities upon exercise of Rights;

     
  (iii)

  (v)

pay when due and payable any and all Canadian and, if applicable, United States, federal, provincial and state 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 Common Shares 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 securities 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 uneder Section 5.1, not take (or permit any Subsidiary to take) any action if at the time such action is taken it is reasonably foreseeable that such action will diminish substantially or otherwise eliminate the benefits intended to be afforded by the Rights.


2.3 Adjustments to Exercise Price; Number of Rights

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

(a)

If the Corporation shall at any time after the Record Time and prior to the Expiration Time:

     
(i)

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

     
(ii)

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

     
(iii)

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

     
(iv)

issue any Common Shares (or other securities exchangeable for or convertible into or giving a right to acquire Common Shares) in respect of, in lieu of or in exchange for existing Common Shares;


- 19 -

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 such that:

  (A)

if the Exercise Price and number of Rights outstanding are to be adjusted;

       
  (I)

the Exercise Price in effect after such adjustment will be equal to the Exercise Price in effect immediately prior to such adjustment divided by the number of Common Shares (or other capital stock) (the "Expansion Factor") that a holder of one Common Share immediately prior to such dividend, subdivision, change, combination or issuance would hold thereafter as a result thereof; and

       
  (II)

each Right held prior to such adjustment will become that number of Rights equal to the Expansion Factor;

       
 

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

       
  (B)

if the securities purchasable upon exercise of Rights are to be adjusted, the securities purchasable upon exercise of each Right after such adjustment will be the securities that a holder of the securities purchasable upon exercise of one Right immediately prior to such dividend, subdivision, change, combination or issuance would hold thereafter as a result thereof.


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

     
(b)

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 Common Shares entitling them (for a period expiring within 45 calendar days after such record date) to subscribe for or purchase Common Shares (or securities convertible into or exchangeable for or carrying a right to purchase Common Shares) at a price per Common Share (or, if a security convertible into or exchangeable for or carrying a right to purchase or subscribe for Common Shares having a conversion, exchange or exercise price, including the price required to be paid to purchase such convertible or exchangeable security or right per share) less than the Market Price per Common Share on such record date, the Exercise Price to be in effect after such record date shall be adjusted to that price determined by multiplying the Exercise Price in effect immediately prior to such record date by a fraction:

     
(i)

the numerator of which shall be the number of Common Shares outstanding on such record date, plus the number of Common Shares that the aggregate offering price of the total number of Common Shares so to be offered (and/or the aggregate initial conversion, exchange or exercise price of the convertible or exchangeable securities or rights so to be offered, including the price required to be paid to purchase such convertible or exchangeable securities or rights) would purchase at such Market Price per Common Share; and


- 20 -

  (ii)

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


If 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 the Rights. Such adjustment shall be made successively whenever such a record date is fixed, and in the event that such rights or warrants are not so issued, or if issued, are not exercised prior to the expiration thereof, the Exercise Price shall be adjusted to be the Exercise Price which would then be in effect if such record date had not been fixed or to the Exercise Price which would be in effect based upon the number of Common Shares (or Convertible Securities) actually issued upon the conversion exercise or exchange of such Convertible Securities or upon exercise of such rights, options or warrants, as the case may be.

     

For purposes of this Agreement, the granting of the right to purchase Common Shares (whether from treasury shares or otherwise) pursuant to any Dividend Reinvestmetn Plan and/or any Common Share purchase plan providing for the reinvestment of dividends or interest payable on securities of the Corporation and/or the investment of periodic optional payments and/or employee benefit, stock option or similar plans (so long as such right to purchase is in no case evidenced by the delivery of rights or warrants) shall not be deemed to constitute an issue of rights or warrants by the Corporation; provided, however, that, in the case of any Dividend Reinvestment Plan, the right to purchase Common Shares is at a price per share of not less than 90 percent of the Market Price of the Common Shares.

     
(c)

If the Corporation shall at any time after the Record Time and prior to the Separation Time fix a record date for a distribution to all holders of Common Shares (including any such distribution made in connection with a merger or amalgamation in which the Corporation is the continuing corporation) of evidences of indebtedness, cash (other than an ordinary course dividend or a dividend referred to in paragraph 2.3(a)(i)), assets or rights 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 Common Share on such record date, less the fair market value (as determined in good faith by the Board of Directors, whose determination shall be described in a statement filed with the Rights Agent and shall be binding on the Rights Agent and the holders of Rights), on a per share basis, of the portion of the cash, assets, evidences of indebtedness, rights, options or warrants so to be distributed; and

     
(ii)

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


- 21 -

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)

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

       
(i)

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

       
(ii)

the record date for the applicable distribution, in the case of an adjustment made pursuant to subsection (b) or (c) above, subject to readjustment to reverse the same if such distribution shall not be made.

       
(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 one percent 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 hundredth of a share. 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 earlier of (i) three years from the date of the transaction which mandates such adjustment and (ii) the Termination Date. Whenever an adjustment to the Exercise Price is made pursuant to this Section 2.3, the Corporation shall:

       
(i)

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

       
(ii)

promptly file with the Rights Agent and with each transfer agent for the Common Shares a copy of such certificate, mail a brief summary thereof to each holder of Rights, and issue a press release advising of the relevant adjustment.

       
(f)

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 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 paragraph (a)(i) or (a)(iv) above, if the Board of Directors acting in good faith determines that the adjustments contemplated by subsections (a), (b) and (c) above in connection with such transaction will not appropriately protect the interests of the holders of Rights, the Board of Directors may determine what other adjustments to the Exercise Price, number of Rights and/or securities purchasable upon exercise of Rights would be appropriate and, notwithstanding subsections (a), (b) and (c) above, but subject to the prior consent of the holders of Common Shares or Rights obtained in accordance with section 5.4, such adjustments, rather than the adjustments contemplated by subsections (a), (b) and (c) above, shall be made. The Corporation and the Rights Agent shall amend this Agreement as appropriate to provide for such adjustments.

       
(g)

Each Right originally issued by the Corporation subsequent to any adjustment made to the Exercise Price hereunder shall evidence the right to purchase, at the adjusted Exercise Price, the number of Common Shares purchasable from time to time hereunder upon exercise of a Right, all subject to further adjustment as provided herein.


- 22 -

(h)

Irrespective of any adjustment or change in the Exercise Price or the number of Common Shares issuable upon the exercise of the Rights, the Rights Certificates theretofore and thereafter issued may continue to express the Exercise Price per Common Share and the number of Common Shares which were expressed in the initial Rights Certificates issued hereunder.

   
(i)

In any case in which this Section 2.3 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Corporation may elect to defer until the occurrence of such event the issuance to the holder of any Right exercised after such record date the number of Common Shares and other securities of the Corporation, if any, issuable upon such exercise over and above the number of Common Shares and other securities of the Corporation, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such adjustment; provided, however, that the Corporation shall deliver to such holder an appropriate instrument evidencing such holder's right to receive such additional shares (fractional or otherwise) or securities upon the occurrence of the event requiring such adjustment.

   
(j)

Notwithstanding anything 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 the Board of Directors shall in good faith determine to be advisable in order that any (i) consolidation or subdivision of the Common Shares, (ii) issuance wholly or in part for cash or Common Shares or securities that by their terms are convertible into or exchangeable for Common Shares, (iii) stock dividends or (iv) issuance of rights, options or warrants referred to in this Section 2.3, hereafter made by the Corporation to holders of its Common Shares shall not be taxable to such shareholders.

   
(k)

The Corporation covenants and agrees that, after the Separation Time, it will not, except as permitted by Section 5.1 or Section 5.4, take (or permit any Subsidiary of the Corporation 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.

   
(l)

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

   
(m)

If the Corporation shall at any time after the Record Time and prior to the earlier of the Separation Time and the Expiration Time issue any Common Shares otherwise than in a transaction referred to in subsection 2.3(a) each such Common Share so issued shall automatically have one new Right associated with it, which Right shall be evidenced by the certificate representing such share.

Each Person in whose name any certificate for Common Shares or other securities, property or assets, if applicable, is issued upon the exercise of Rights shall for all purposes be deemed to have become the holder of record of the Common Shares or other securities, property or assets, if applicable, 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 Corporation are closed, such Person shall be deemed to have become the record holder of such Common Shares or other securities, property or assets on, and such certificate shall be dated, the next succeeding Business Day on which the Common Share transfer books of the Corporation are open.

- 23 -

2.5 Execution, Authentication, Delivery and Dating of Rights Certificates

(a)

The Rights Certificates shall be executed on behalf of the Corporation by any two of its Chairman, President, Vice Presidents or Corporate Secretary. 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 Corporation shall bind the Corporation notwithstanding that such individuals or any of them have ceased to hold such offices prior to the countersignature and delivery of such Rights Certificates.

   
(b)

Promptly after the Corporation learns of the Separation Time, the Corporation will notify the Rights Agent in writing of such Separation Time and will deliver Rights Certificates executed by the Corporation to the Rights Agent for countersignature, and disclosure statements describing the Rights, 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). 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 Corporation will cause to be kept a register (the "Rights Register") in which, subject to such reasonable regulations as it may prescribe, the Corporation will provide for the registration and transfer of Rights. The Rights Agent is hereby appointed registrar for the Rights (the "Rights Registrar") for the purpose of maintaining the Rights Register for the Corporation and registering Rights and transfers of Rights as herein provided and the Rights Agent hereby accepts such appointment. If the Rights Agent shall cease to be the Rights Registrar, the Rights Agent will have the right to examine the Rights Register at all reasonable times.

   
(b)

After the Separation Time and prior to the Expiration Time, upon surrender for registration of transfer or exchange of any Rights Certificate, and subject to the provisions of subsections 2.6(d) and 3.1(b), the Corporation will execute, and the Rights Agent will countersign and deliver, in the name of the holder or the designated transferee or transferees, as required pursuant to the holder's instructions, one or more new Rights Certificates evidencing the same aggregate number of Rights as did the Rights Certificates so surrendered.

   
(c)

All Rights issued upon any registration of transfer or exchange of Rights Certificates shall be the valid obligations of the Corporation, and such Rights shall be entitled to the same benefits under this Agreement as the Rights surrendered upon such registration of transfer or exchange.

   
(d)

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


- 24 -

(e)

The Corporation shall not be required to register the transfer of Rights after the Rights have been terminated pursuant to the provisions of this Agreement.


2.7 Mutilated, Destroyed, Lost and Stolen Rights Certificates

(a)

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

     
(b)

If there shall be delivered to the Corporation and the Rights Agent prior to the Expiration Time:

     
(i)

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

     
(ii)

such security or indemnity as may be reasonably required by 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 Corporation or the Rights Agent that such Rights Certificate has been acquired by a bona fide purchaser, the Corporation shall execute and upon the Corporation's request the Rights Agent shall countersign and deliver, in lieu of any such destroyed, lost or stolen Rights Certificate, a new Rights Certificate evidencing the same number of Rights as did the Rights Certificate so destroyed, lost or stolen.

     
(c)

As a condition to the issuance of any new Rights Certificate under this Section 2.7, the Corporation may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Rights Agent) connected therewith.

     
(d)

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


2.8

Persons Deemed Owners

The Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the Person in whose name a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) is registered as the absolute owner thereof and the Rights evidenced thereby for all purposes whatsoever. As used in this Agreement, unless the context otherwise requires, the term "holder" of any Rights shall mean the registered holder of such Rights (or, prior to the Separation Time, the associated Common Shares).

2.9 Delivery and Cancellation of Certificates

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

- 25 -

2.10 Agreement of Rights Holders

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

(a)

to be bound by and subject to the provisions of this Agreement, as amended from time to time in accordance with the terms hereof, in respect of all Rights held;

   
(b)

that, prior to the Separation Time, each Right will be transferable only together with, and will be transferred by a transfer of, the associated Common Share;

   
(c)

that after the Separation Time, the Rights Certificate will be transferable only upon registration of the transfer on the Rights Register as provided herein;

   
(d)

that, prior to due presentment of a Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) for registration of transfer, the Corporation, the Rights Agent and any agent of the Corporation or the Rights Agent may deem and treat the person in whose name the Rights Certificate (or, prior to the Separation Time, the associated Common Share certificate) is registered as the absolute owner thereof and of the Rights evidenced thereby (notwithstanding any notations of ownership or writing on such Rights Certificate or the associated Common Share certificate made by anyone other than the Corporation or the Rights Agent) for all purposes whatsoever, and neither the Corporation nor the Rights Agent shall be affected by any notice to the contrary;

   
(e)

that such holder of Rights has waived his right to receive any fractional Rights or any fractional shares upon exercise of a Right (except as provided herein);

   
(f)

that, in accordance with 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 Agreemet or is otherwise defective pursuant to and as provided herein; and

   
(g)

that notwithstanding anything in this Agreement to the contrary, neither the Corporation nor the Rights Agent shall have any liability to any holder of a Right or any other Person as a result of its inability to perform any of its obligations under this Agreement by reasons of any 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.


2.11 Rights Certificate Holder not Deemed a Shareholder

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

ARTICLE 3
ADJUSTMENTS TO THE RIGHTS IN THE EVENT OF CERTAIN TRANSACTIONS

3.1 Flip-in Event

(a)

Subject to subsections 3.1(b), 5.1(a) and 5.1(e), if prior to the Expiration Time a Flip-in Event occurs, each Right shall constitute, effective at the close of business on the tenth Trading Day after the Stock Acquisition Date, the right to purchase from the Corporation, upon payment of the Exercise Price and otherwise exercising such Right 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 in event that after the Stock Acquisition Date an event of a type analogous to any of the events described in Section 2.3 has occurred).

     
(b)

Notwithstanding anything in this Agreement to the contrary, upon the occurrence of any Flip-in Event, any Rights that are or were Beneficially Owned on or after the earlier of the Separation Time and 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 any Associate or Affiliate of an Acquiring Person); or

     
(ii)

a transferee of Rights, direct or indirect, of an Acquiring Person (or of any Affiliate or Associate of an Acquiring Person or of any Person acting jointly or in concert with an Acquiring Person or any Associate or Affiliate of an Acquiring Person) who becomes a transferee 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 Associate or Affiliate of an Acquiring Person), that has the purpose or effect of avoiding paragraph 3.1(b)(i);

shall become null and void without any further action, and any holder of such Rights (including any transferee of, or other successor to, such Rights, whether directly or indirectly) shall not have any right whatsoever to exercise such Rights under any provision of this Agreement and shall not have thereafter any right 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 become null and void.

- 27 -

(c)

Any Rights Certificate that represents Rights Beneficially Owned by a Person described in either paragraph 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 an Affiliate or an Associate of an Acquiring Person (as such terms are defined in the Rights Agreement) or a Person acting jointly or in concert with any of them. This Rights Certificate and the Rights represented hereby are void in the circumstances specified in subsection 3.1(b) of the Rights Agreement.


provided 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 in writing 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 either paragraph 3.1(b)(i) or (ii).

   
(d)

From and after the Separation Time, the Corporation 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 (Alberta) and the Securities Act (Alberta) and any other applicable laws in respect of the issue of Common Shares upon the exercise of Rights in accordance with this Agreement.


3.2 Fiduciary Duties of the Board of Directors of the Corporation

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

ARTICLE 4
THE RIGHTS AGENT

4.1 General

(a)

The Corporation hereby appoints the Rights Agent to act as agent for the Corporation in accordance with the terms and conditions hereof, and the Rights Agent hereby accepts such appointment. The Corporation may from time to time appoint such co-Rights Agents ("Co-Rights Agents") as it may deem necessary or desirable, subject to the approval of the Rights Agent. In the event the Corporation appoints one or more Co-Rights Agents, the respective duties of the Rights Agents and the Co-Rights Agents shall be as the Corporation may determine with the approval of the Rights Agent and the Co-Rights Agent. The Corporation agrees to pay to the Rights Agent reasonable compensation for all services rendered by it hereunder and, from time to time, on demand of the Rights Agent, its reasonable expenses and 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 retained by the Rights Agent. The Corporation also agrees to indemnify the Rights Agent, its officers, directors, employees and agents for, and to hold them harmless against, any loss, liability, costs, claims, actions, damages or expenses, incurred without gross negligence, fraud or wilful misconduct on the part of the Rights Agent, for anything done or suffered or omitted by the Rights Agent in connection with the acceptance, execution and administration of this Agreement and the 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 or the resignation or removal of the Rights Agent.


- 28 -

(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 acceptance, execution and administration of this Agreement in reliance upon any certificate for Voting Shares or Common Shares, or any Rights Certificate or certificate for other securities of the Corporation, instrument of assignment or transfer, power of attorney, endorsement, affidavit, letter, notice, direction, consent, certificate, statement, or other paper or document believed by it to be genuine and to be signed, executed and, where necessary, verified or acknowledged, by the proper Person or Persons.

   
(c)

The Corporation shall inform the Rights Agent in a reasonably timely manner of events which may materially affect the administration of this Agreement by the Rights Agent and at any time upon request, shall provide to the Rights Agent an incumbency certificate with respect to the then current directors of the Corporation, provided that failure to inform the Rights Agent of any such event, 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. In case at the time each 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)

If 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 Certificate 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.


- 29 -

4.3 Duties of Rights Agent

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

(a)

the Rights Agent may retain, at the expense of the Corporation, and consult with legal counsel (who may be legal counsel for the Corporation) and the opinion of such counsel will be full and complete authorization and protection to the Rights Agent as to any action taken, suffered or omitted by it in good faith and in accordance with such opinion; the Rights Agent may also, with the approval of the Corporation (such approval not to be unreasonably withheld), consult with such other experts as the Rights Agent shall consider necessary or appropriate to properly carry out the duties and obligations imposed under this Agreement and the Rights Agent shall be entitled to act and rely in good faith on the advice of any such expert;

   
(b)

whenever in the performance of its duties under this Agreement the Rights Agent deems it necessary or desirable that any fact or matter be proved or established by the Corporation prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a certificate signed by a Person believed by the Rights Agent to be the Chairman of the Board, the President, any Vice President or the Corporate Secretary of the Corporation and delivered to the Rights Agent; and such certificate will be full authorization to the Rights Agent for any action taken or suffered in good faith by it under the provisions of this Agreement in reliance upon such certificate;

   
(c)

the Rights Agent will be liable hereunder only for its own gross negligence, fraud 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 Voting Shares or Common Shares or the Rights Certificates (except its countersignature thereof) or be required to verify the same, but all such statements and recitals are and will be deemed to have been made by the Corporation only;

   
(e)

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


- 30 -

(f)

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

     
(g)

the Rights Agent is hereby authorized and directed to accept written instructions with respect to the performance of its duties hereunder from any person believed by the Rights Agent to be the Chairman of the Board, the President, any Vice President or the Corporate Secretary of the Corporation, and to apply to such individual 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 reliance upon instructions of any such individual;

     
(h)

the Rights Agent and any shareholder or stockholder, director, officer or employee of the Rights Agent may buy, sell or deal in Common Shares, Rights or other securities of the Corporation or become pecuniarily interested in any transaction in which the Corporation may be interested, or contract with or lend money to the Corporation or otherwise act as fully and freely as though it were not Rights Agent under this Agreement. Nothing herein shall preclude the Rights Agent from acting in any other capacity for the Corporation or for any other legal entity; and

     
(i)

the Rights Agent may execute and exercise any of the rights or powers hereby vested in it or perform any duty hereunder either itself or by or through its attorneys or agents, and the Rights Agent will not be answerable or accountable for any act, default, neglect or misconduct of any such attorneys or agents or for any loss to the Corporation resulting from any such act, default, neglect or misconduct, provided reasonable care was exercised in the selection and continued employment thereof.


4.4 Change of Rights Agent

The Rights Agent may resign and be discharged from its duties under this Agreement upon 30 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 registered or certified mail in accordance with Section 5.9 at the expense of the Corporation. The Corporation may remove the Rights Agent upon 30 days' notice in writing, mailed to the Rights Agent and to each transfer agent of the Common Shares by registered or certified mail in accordance with Section 5.9. If the Rights Agent should resign or be removed or otherwise become incapable of acting, the Corporation will appoint a successor to the Rights Agent. If the Corporation fails to make such appointment within a period of 30 days after such removal or after it has been notified in writing of such resignation or incapacity by the resigning or incapacitated Rights Agent then the resigning Rights Agent (at the Corporation's expense) or 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 corporation incorporated under the laws of Canada or a province thereof authorized to carry on the business of a trust company. 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 upon payment of its outstanding fees and expenses the predecessor Rights Agent shall deliver and transfer to the successor Rights Agent any property at the time held by it hereunder, and execute and deliver any further assurance, conveyance, act or deed necessary for the purpose. Not later than the effective date of any such appointment, the Corporation will file notice thereof in writing with the predecessor Rights Agent and each transfer agent of the Common Shares and give notice thereof to the holders of the Rights in accordance with Section 5.9. Failure to give any notice provided for in this Section 4.4, however, or any defect therein, shall not affect the legality or validity of the resignation or removal of the Rights Agent or the appointment of the successor Rights Agent, as the case may be.

- 31 -

ARTICLE 5
 MISCELLANEOUS

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, waive the application of Section 3.1 to a particular Flip-in Event that would result from a Take-over Bid made by way of take-over bid circular to all holders of record of Voting Shares (which for greater certainty shall not include the circumstances described in subsection 5.1(e)); provided that if the Board of Directors waive 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 occurring by reason of any Take-over Bid which is made by means of a take-over bid circular to all holders of record of Voting Shares prior to the expiry of any Take-over Bid (as the same may be extended from time to time) in respect of which a waiver is, or is deemed to have been, granted under this subsection 5.1(a).

   
(b)

The Board of Directors acting in good faith may, at its option, at any time prior to the occurrence of a Flip-in Event, elect to redeem all but not less than all of the then outstanding Rights at a redemption price of $0.00001 per Right appropriately adjusted in a manner analogous to the applicable adjustment provided for in Section 2.3 if an event of the type analogous to any of the events described in Section 2.3 shall have occurred (such redemption price being herein referred to as the "Redemption Price").

   
(c)

If the Board of Directors elects or is deemed to have elected 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.

   
(d)

Within 10 days after the Board of Directors electing or having been deemed to have elected to redeem the Rights, the Corporation shall give notice of redemption to the holders of the Rights in accordance with Section 5.9. Each such notice of redemption will state the method by which the payment of the Redemption Price will be made. The Corporation may not redeem, acquire or purchase for value any Right at any time in any manner other than that specifically set forth in this Section 5.1 or other than in connection with the purchase of Common Shares prior to the Separation Time.

   
(e)

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 eight Trading Days following a Stock Acquisition Date that a Person became an Acquiring Person by inadvertence and without any intention to become, or knowledge that it would become, an Acquiring Person under this Agreement and, in the event that such a waiver is granted by the Board of Directors, such Stock Acquisition Date shall be deemed not to have occurred. Any such waiver pursuant to this subsection 5.1(e) must be on the condition that such Person, within 10 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 Stock Acquisition Date and Section 3.1 shall apply thereto.


- 32 -

(f)

Where, pursuant to a Permitted Bid, a Competing Permitted Bid or an Exempt Acquisition under subsection 5.1(a), a Person acquires outstanding Voting Shares, other than Voting Shares Beneficially Owned by such Person at the date of the Permitted Bid, the Competing Permitted Bid or the Exempt Acquisition under subsection 5.1(a), then the Board of Directors shall immediately upon the consummation of such acquisition without further formality and without any approval under subsections 5.4(b) or 5.4(c) be deemed to have elected to redeem the Rights at the Redemption Price..

   
(g)

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.

   
(h)

Upon the Rights being redeemed pursuant to subsection 5.1(g), all the provisions of this Agreement shall continue to apply as if the Separation Time had not occurred and Rights Certificates representing the number of Rights held by each holder of record of Common Shares as of the Separation Time had not been mailed to each such holder and for all purposes of this Agreement the Separation Time shall be deemed not to have occurred.

   
(i)

The Board of Directors may, prior to the close of business on the tenth Trading Day following a Stock Acquisition Date or such later Business Day as the Board of Directors may from time to time determine, upon prior written notice delivered to the Rights Agent, waive the application of Section 3.1 to the related Flip-in Event, provided that the Acquiring Person has reduced its Beneficial Ownership of Voting Shares (or has entered into a contractual arrangement with the Corporation, acceptable to the Corporation, to do so within 10 days of the date on which such contractual arrangement is entered into or such other date as the Board of Directors may have determined) such that at the time the waiver becomes effective pursuant to this subsection 5.1(h) such Person is no longer an Acquiring Person. In the event of such a waiver becoming effective prior to the Separation Time, for the purposes of this Agreement such Flip-in Event shall be deemed not to have occurred.


5.2 Expiration

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

5.3 Issuance of New Rights Certificates

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

5.4 Supplements and Amendments

(a)

Without the approval of any holders of Voting Shares or Rights, the Corporation may make amendments or supplements to this Agreement to correct any clerical or typographical error or which are required to maintain the validity of the Agreement as a result of any change in any applicable legislation, regulations or rules thereunder. In addition, without approval of any holders of Voting Shares or Rights, the Corporation may, prior to the date of the initial meeting of Shareholders to confirm this Agreement as contemplated by Section 5.17 hereof, amend, vary, delete, rescind or supplement any of the provisions of this Agreement and the Rights (whether or not such action would materially adversely affect the interests of holders of Rights generally). The Corporation may in addition 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 supplement or amendment shall be made to the provisions of Article 4 except with the written concurrence of the Rights Agent to such change, supplement or amendment.


- 33 -

(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 and entitled to vote 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 by-laws and the Business Corporations Act (Alberta) with respect to meetings of shareholders of the Corporation.

5.6 Rights of Action

Subject to the terms of this Agreement, all rights of action in respect of this Agreement, other than rights of action vested solely in the Rights Agent, are vested in the respective registered holders of the Rights; and any registered holder of any Rights, without the consent of the Rights Agent or of the registered 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 such holder's right to exercise such holder's Rights in the manner provided in such holder's Rights Certificate and in this Agreement. Without limiting the foregoing or any remedies available to the holders of Rights, it is specifically acknowledged that the holders of Rights would not have an adequate remedy at law for any breach of this Agreement and will be entitled to specific performance of the obligations under, and injunctive relief against actual or threatened violations of the obligations of any person subject to, this Agreement.

5.7 Regulatory Approvals

Any obligation of the Corporation or action or event contemplated by this Agreement shall be subject to the receipt of any requisite approval or consent from any governmental or regulatory authority, and, without limitation, necessary approval of the Toronto Stock Exchange shall be obtained, such as to the issuance of Common Shares upon the exercise of Rights under subsection 2.2(d) . Notwithstanding any provision of this Agreement, any amendment to this Agreement will be subject to the prior written consent of the Toronto Stock Exchange.

5.8 Unlawful Distributions

If in the opinion of the Board of Directors (who may rely upon the advice of counsel) any action or event contemplated by this Agreement would require compliance by the Corporation with the securities laws or comparable legislation of a jurisdiction outside Canada or the United States, the Board of Directors acting in good faith shall take such actions as it may deem appropriate to ensure that such compliance is not required, including, without limitation, establishing procedures for the issuance to a Canadian or the United States resident trustee of Rights or securities issuable on exercise of Rights, the holding thereof in trust for the Persons entitled thereto (but reserving to the trustee or to the trustee and the Corporation, as the Corporation may determine, absolute investment discretion with respect thereto) and the sale thereof and remittance of proceeds of such sale, if any, to the Persons entitled thereto. In no event shall the Corporation or the Rights Agent be required to issue or deliver Rights or securities issuable on exercise of Rights to Persons who are citizens, residents or nationals of any jurisdiction other than Canada or the United States, in which such issue or delivery would be unlawful without registration of the relevant Persons or securities for such purposes. Notwithstanding the foregoing, to the extent that the issuance or delivery of the Rights or securities issuable on exercise of Rights to Persons who are citizens, residents or nationals of any such jurisdiction in which such issue or delivery would be so unlawful, such Rights or securities shall be issued and delivered to such Persons to the extent the same may be so issued and delivered in reliance upon applicable exemptions from registration requirements in such jurisdictions.

Rights Certificate

This certifies that _______________________________________ , or its registered assigns, is the registered holder of the number of Rights set forth above, each of which entitles the registered holder thereof, subject to the terms, provisions and conditions of the Shareholder Protection Rights Plan Agreement dated as of March 13, 2008 and amended and restated as of March 15, 2011 (the "Rights Agreement") between TransGlobe Energy Corporation, a corporation incorporated under the Business Corporations Act (Alberta) (the "Corporation") and Olympia Trust Company, a trust company, as rights agent (the "Rights Agent") (which term shall include any successor Rights Agent under the Rights Agreement), to purchase from the Corporation at any time after the Separation Time (as such term is defined in the Rights Agreement) and prior to the Expiration Time (as such term is defined in the Rights Agreement), one fully paid common share of the Corporation (a "Common Share") at the Exercise Price referred to below, upon presentation and surrender of this Rights Certificate together with the Form of Election to Exercise duly executed and submitted to the Rights Agent at its principal office in the city of Toronto. Until adjustment thereof in certain events as provided in the Rights Agreement, the Exercise Price is Fifty ($50.00) dollars.

In certain circumstances described in the Rights Agreement, each Right evidenced hereby may entitle the registered holder thereof to purchase or receive securities of an entity other than the Corporation, assets, debt, equity or other securities or property or assets of the Corporation, or more or less than one Common Share (or a combination thereof), all as provided in the Rights Agreement.

The Rights Certificate is subject to all of the terms, provisions and conditions of the Rights Agreement which terms, provisions and conditions are hereby incorporated herein by reference and made a part thereof and to which Rights Agreement reference is hereby made for a full description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Rights Agent, the Corporation and the holders of the Rights Certificates.

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