     AND WHEREAS each Right entitles the holder thereof, after the Separation

subject to the conditions set forth herein;

     AND WHEREAS the Corporation desires to appoint the Rights Agent to act on
behalf of the Corporation and the holders of Rights, and the Rights Agent is
willing to so act, in connection with the issuance, transfer, exchange and

Rights and other matters referred to herein;

     AND WHEREAS this agreement was originally entered into by the Corporation

               that this exception shall not be, and shall cease to be,

               Grandfathered Person shall, after the Record Time, become the
               Beneficial Owner of additional Voting Shares of the Corporation
               that increases its Beneficial Ownership of Voting Shares by more
               than 1% of the number of Voting Shares outstanding as at the
               Record Time (other than pursuant to one or any combination of a
               Voting Share Reduction, a Permitted Bid Acquisition, an Exempt
               Acquisition or a Pro Rata Acquisition);

     (b)  "AFFILIATE" when used to indicate a relationship with a Person means a
          Person that directly, or indirectly through one or more

               the Rights Certificates, or certificates for Common Shares to be
               issued upon exercise of any Rights, provided that the Corporation
               shall not be required to pay any transfer tax or charge which may
               be payable in respect of any transfer involved in the transfer or
               delivery of Rights Certificates or the issuance or delivery of
               certificates for Common Shares in a name other than that of the

               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 (or other securities exchangeable for or
               convertible into or giving a right to acquire Common Shares or
               other securities of the Corporation) 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 and the number of Rights outstanding, or, if the
          payment or effective date therefore shall occur after the Separation
          Time, the securities purchasable upon exercise of Rights shall be
          adjusted as of the payment or effective date in the manner set forth
          below.

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

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

          (y)  each Right held prior to such adjustment will become that number
               of Rights equal to the Expansion Factor,

          and the adjusted number of Rights will be deemed to be distributed
          among the Common Shares with respect to which the original Rights were
          associated (if they remain outstanding) and the shares issued in
          respect of such dividend, subdivision, change, consolidation or
          issuance, so that each such Common Share (or other capital stock) will
          have exactly one Right associated with it following the payment or
          effective date of the event referred to in Clause 2.3(a)(i), (ii),
          (iii) or (iv), as the case may be.

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

          If, after the Record Time and prior to the Expiration Time, the
          Corporation shall issue any shares of capital stock other than Common
          Shares in a transaction of a type described in Clause 2.3(a)(i) or
          (iv), shares of such capital stock shall be treated herein as nearly
          equivalent to Common Shares as may be practicable and


                                     - 21 -


          appropriate under the circumstances and the Corporation and the Rights
          Agent agree to amend this Agreement in order to effect such treatment.

          In the event the Corporation shall at any time after the Record Time
          and prior to the Separation Time issue any Common Shares otherwise
          than in a transaction referred to in this 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 associated Common Share.

     (b)  In the event 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
          determined by multiplying the Exercise Price in effect immediately
          prior to such record date by a fraction:

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

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

          In case such subscription price may be paid by delivery of
          consideration, part or all of which may be in a form other than cash,
          the value of such consideration shall be as determined in good faith
          by the Board of Directors, whose determination shall be described in a
          statement filed with the Rights Agent and shall be binding on the
          Rights Agent and the holders of Rights. Such adjustment shall be made
          successively whenever such a record date is fixed, and in the event
          that such rights, options or warrants are not so issued, or if issued,
          are not exercised prior to the expiration thereof, the Exercise Price
          shall be readjusted to the Exercise Price which would then be in
          effect if such record date had not been


                                     - 22 -


          fixed, or to the Exercise Price which would be in effect based upon
          the number of Common Shares (or securities convertible into, or
          exchangeable or exercisable for Common Shares) actually issued upon
          the exercise of such rights, options or warrants, as the case may be.

          For purposes of this Agreement, the granting of the right to purchase
          Common Shares (whether from treasury or otherwise) pursuant to the
          Dividend Reinvestment Plan or any employee benefit, stock option or
          similar plans shall be deemed not to constitute an issue of rights,
          options or warrants by the Corporation; provided, however, that, in
          all such cases, the right to purchase Common Shares is at a price per
          share of not less than 95 per cent of the current market price per
          share (determined as provided in such plans) of the Common Shares.

     (c)  In the event the Corporation shall at any time after the Record Time
          and prior to the Separation Time fix a record date for the making of a
          distribution to all holders of Common Shares (including any such
          distribution made in connection with a merger or amalgamation) of
          evidences of indebtedness, cash (other than an annual cash dividend or
          a dividend paid in Common Shares, but including any dividend payable
          in securities other than Common Shares), assets or rights, options or
          warrants (excluding those referred to in Subsection 2.3(b)), the
          Exercise Price to be in effect after such record date shall be
          determined by multiplying the Exercise Price in effect immediately
          prior to such record date by a fraction:

          (i)  the numerator of which shall be the Market Price per 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.

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

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


                                     - 23 -


          Subsection 2.3(d), any adjustment required by Section 2.3 shall be
          made no later than the earlier of:

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

          (ii) the Expiration Date.

     (e)  In the event the Corporation shall at any time after the Record Time
          and prior to the Separation Time issue any shares of capital stock
          (other than Common Shares), or rights, options or warrants to
          subscribe for or purchase any such capital stock, or securities
          convertible into or exchangeable for any such capital stock, in a
          transaction referred to in Clause 2.3(a)(i) or (iv), if the Board of
          Directors acting in good faith determines that the adjustments
          contemplated by Subsections 2.3(a), (b) and (c) in connection with
          such transaction will not appropriately protect the interests of the
          holders of Rights, the Board of Directors may determine what other
          adjustments to the Exercise Price, number of Rights and/or
          securities purchasable upon exercise of Rights would be appropriate
          and, notwithstanding Subsections 2.3(a), (b) and (c), such
          adjustments, rather than the adjustments contemplated by Subsections
          2.3(a), (b) and (c), shall be made. Subject to the prior consent of
          the holders of the Voting Shares or the Rights obtained as set forth
          in Subsection 5.4(b) or (c), the Corporation and the Rights Agent
          shall have authority to amend this Agreement as appropriate to
          provide for such adjustments.

     (f)  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 immediately prior to such issue, all subject to further
          adjustment as provided herein.

     (g)  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.

     (h)  In any case in which this Section 2.3 shall require that an
          adjustment in the Exercise rice 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


                                     - 24 -


          receive such additional shares (fractional or otherwise) or other
          securities upon the occurrence of the event requiring such adjustment.

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

          (i)  consolidation or subdivision of Common Shares;

          (ii) issuance (wholly or in part for cash) of Common Shares or
               securities that by their terms are convertible into or
               exchangeable for Common Shares;

         (iii) stock dividends; or

          (iv) issuance of rights, options or warrants referred to in this
               Section 2.3,

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

2.4  DATE ON WHICH EXERCISE IS EFFECTIVE

     Each Person in whose name any certificate for Common Shares or other
securities, if applicable, is issued upon the exercise of Rights shall for all
purposes be deemed to have become the holder of record of the Common Shares or
other securities, if applicable, represented thereon, and such certificate shall
be dated the date upon which the Rights Certificate evidencing such Rights was
duly surrendered in accordance with Subsection 2.2(d) (together with a duly
completed Election to Exercise) and payment of the Exercise Price for such
Rights (and any applicable transfer taxes and other governmental charges payable
by the exercising holder hereunder) was made; provided, however, that if the
date of such surrender and payment is a date upon which the Common Share
transfer books of the Corporation are closed, such Person shall be deemed to
have become the record holder of such shares on, and such certificate shall be
dated, the next succeeding Business Day on which the Common Share transfer books
of the Corporation are open.

2.5  EXECUTION, AUTHENTICATION, DELIVERY AND DATING OF RIGHTS CERTIFICATES

     (a)  The Rights Certificates shall be executed on behalf of the Corporation
          by its Chairman of the Board, President or any Vice President and by
          its Corporate Secretary or any Assistant Secretary under the corporate
          seal of the Corporation reproduced thereon. The signature of any of
          these officers on the Rights Certificates may be manual or facsimile.
          Rights Certificates bearing the manual or facsimile signatures of
          individuals who were at any time the proper officers of the
          Corporation shall bind the Corporation, notwithstanding that such
          individuals or any of them have ceased to hold such offices either
          before or after the countersignature and delivery of such Rights
          Certificates.


                                     - 25 -


     (b)  Promptly after the Corporation learns of the Separation Time, the
          Corporation will notify the Rights Agent of such Separation Time and
          will deliver Rights Certificates executed by the Corporation to the
          Rights Agent for countersignature, and the Rights Agent shall manually
          countersign (in a manner satisfactory to the Corporation) and send
          such Rights Certificates to the holders of the Rights pursuant to
          Subsection 2.2(c) hereof. No Rights Certificate shall be valid for any
          purpose until countersigned by the Rights Agent as aforesaid.

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

2.6  REGISTRATION, TRANSFER AND EXCHANGE

     (a)  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. 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), the
          Corporation will execute, and the Rights Agent will manually
          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 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.

     (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 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 reasonable fees and
          expenses of the Rights Agent) connected therewith.

                                     - 26 -


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 them
               to save each of them and any of their agents harmless;

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

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

2.8  PERSONS DEEMED OWNERS OF RIGHTS

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


                                     - 27 -


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, subject to applicable laws, destroy all cancelled Rights
Certificates and deliver a certificate of destruction to the Corporation.

2.10 AGREEMENT OF RIGHTS HOLDERS

     Every holder of Rights, by accepting 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 certificate representing such Right;

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

     (d)  that prior to due presentment of a Rights Certificate (or, prior to
          the Separation Time, the associated Common Share certificate) for
          registration of 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 or other securities upon
          exercise of a Right (except as provided herein);

     (f)  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
          reason of any preliminary or permanent injunction or


                                     - 28 -


          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; and

     (g)  that, subject to the provisions of Section 5.4, without the approval
          of any holder of Rights or Voting Shares and upon the sole authority
          of the Board of Directors, acting in good faith, this Agreement may be
          supplemented or amended from time to time to cure any ambiguity or to
          correct or supplement any provision contained herein which may be
          inconsistent with the intent of this Agreement or is otherwise
          defective, as provided herein.

2.11 RIGHTS CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER

     No holder, as such, of any Rights or Rights Certificate shall be entitled
to vote, receive dividends or be deemed for any purpose whatsoever the holder of
any 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 right, title, benefit or privilege 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 Common Shares or any other
shares of the Corporation at any meeting thereof, or to give or withhold consent
to any action of the Corporation, or to receive notice of any meeting or other
action affecting any holder of Common Shares or any other shares of the
Corporation except as expressly provided herein, or to receive dividends,
distributions or subscription rights, or otherwise, until the 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

3.1  FLIP-IN EVENT

     (a)  Subject to Subsection 3.1(b) and Section 5.1, in the event that prior
          to the Expiration Time a Flip-in Event shall occur, each Right shall
          constitute, effective at the close of business on the eighth Trading
          Day after the Stock Acquisition Date, the right to purchase from the
          Corporation, 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 in
          the event that after such consummation or occurrence, an event of a
          type analogous to any of the events described in Section 2.3 shall
          have occurred).


                                     - 29 -


     (b)  Notwithstanding anything in this Agreement to the contrary, upon the
          occurrence of any Flip-in Event, any Rights that are or were
          Beneficially Owned on or after the earlier of the Separation Time or
          the Stock Acquisition Date by:

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

          (ii) a transferee of Rights, directly or indirectly, from an Acquiring
               Person (or any Affiliate or Associate of an Acquiring Person or
               any Person acting jointly or in concert with an Acquiring Person
               or any Affiliate or Associate of an Acquiring Person), where such
               transferee becomes a transferee concurrently with or subsequent
               to the Acquiring Person becoming such in a transfer that the
               Board of Directors has determined is part of a plan, arrangement
               or scheme of an Acquiring Person (or any Affiliate or Associate
               of an Acquiring Person or any Person acting jointly or in concert
               with an Acquiring Person or any Affiliate or Associate of an
               Acquiring Person), that has the purpose or effect of avoiding
               Clause 3.1(b)(i),

          shall become null and void without any further action, and any holder
          of such Rights (including transferees) shall thereafter have no right
          to exercise such Rights under any provision of this Agreement and
          further shall thereafter not have any other rights whatsoever with
          respect to such Rights, whether under any provision of this Agreement
          or otherwise.

     (c)  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 CANADA BUSINESS CORPORATIONS ACT, the SECURITIES
          ACT (Alberta) 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 issued to
               a Person who was an Acquiring Person or an Affiliate or an
               Associate of an Acquiring Person (as such terms are defined in
               the Shareholder Rights Plan Agreement) or a Person who was acting
               jointly or in concert with an Acquiring Person or an Affiliate or
               Associate of an Acquiring Person. This Rights Certificate and the
               Rights represented hereby are void or shall


                                     - 30 -


               become void in the circumstances specified in Subsection 3.1(b)
               of the Shareholder Rights Plan Agreement.

          provided, however, that the Rights Agent shall not be under any
          responsibility to ascertain the existence of facts that would require
          the imposition of such legend but shall impose such legend only if
          instructed to do so by the Corporation 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.


                          ARTICLE 4 - THE RIGHTS AGENT

4.1  GENERAL

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

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

4.2  MERGER, AMALGAMATION OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT

     (a)  Any corporation into which the Rights Agent may be merged or
          amalgamated or with which it may be consolidated, or any corporation
          resulting from any merger, amalgamation, statutory arrangement or
          consolidation to which the Rights Agent is a party, or any corporation
          succeeding to the shareholder or stockholder services business of the
          Rights Agent, will be the successor to the Rights Agent


                                     - 31 -


          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 successor Rights Agent may adopt the
          countersignature of the predecessor Rights Agent and deliver such
          Rights Certificates so countersigned; and in case at that time any of
          the Rights have not been countersigned, any successor Rights Agent may
          countersign such Rights Certificates in the name of the predecessor
          Rights Agent or in the name of the successor Rights Agent; and in all
          such cases such Rights Certificates will have the full force provided
          in the Rights Certificates and in this Agreement.

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

4.3  DUTIES OF RIGHTS AGENT

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

     (a)  the Rights Agent may consult with legal counsel (who may be legal
          counsel for the Corporation) and the opinion of such counsel will be
          full and complete authorization and protection to the Rights Agent as
          to any action taken or omitted by it in good faith and in accordance
          with such opinion;

     (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, President, any Vice President, Treasurer, Corporate
          Secretary, or any Assistant 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;


                                     - 32 -


     (c)  the Rights Agent will be liable hereunder for its own 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 in 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 execution and delivery hereof
          (except the due authorization, execution and delivery hereof by the
          Rights Agent) or in respect of the validity or execution of any
          certificate for a Common Share or Rights Certificate (except its
          countersignature thereof); nor will it be responsible for any breach
          by the 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 exerciseability of the Rights (including the Rights
          becoming void pursuant to Subsection 3.1(b) hereof) or any adjustment
          required under the provisions of Section 2.3 hereof or responsible for
          the manner, method or amount of any such adjustment or the
          ascertaining of the existence of facts that would require any such
          adjustment (except with respect to the exercise of Rights after
          receipt of the certificate contemplated by Section 2.3 describing any
          such adjustment); nor will it by any act hereunder be deemed to make
          any representation or warranty as to the authorization of any Common
          Shares to be issued pursuant to this Agreement or any Rights or as to
          whether any Common Shares will, when issued, be duly and validly
          authorized, executed, issued and delivered and fully paid and
          non-assessable;

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

     (g)  the Rights Agent is hereby authorized and directed to accept
          instructions in writing with respect to the performance of its duties
          hereunder from any individual believed by the Rights Agent to be the
          Chairman of the Board, President, any Vice President, Treasurer,
          Corporate Secretary or any Assistant Secretary of the Corporation, and
          to apply to such individuals for advice or instructions in connection
          with its duties, and it shall not be liable for any action taken or
          suffered by it in good faith in accordance with instructions of any
          such individual;

     (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


                                     - 33 -


          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 60 days' notice (or such lesser notice as is acceptable to the
Corporation) in writing mailed to the Corporation and to each transfer agent of
Common Shares by registered or certified mail. The Corporation may remove the
Rights Agent upon 60 days' notice in writing, mailed to the Rights Agent and to
each transfer agent of the Common Shares by registered or certified mail. If the
Rights Agent should resign or be removed or otherwise become incapable of
acting, the Corporation will appoint a successor to the Rights Agent. If the
Corporation fails to make such appointment within a period of 60 days after such
removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent, then by prior written
notice to the Corporation the resigning Rights Agent or the holder of any Rights
(which holder shall, with such notice, submit such holder's Rights Certificate,
if any, for inspection by the Corporation), 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 in the Province of
Alberta. After appointment, the successor Rights Agent will be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent shall deliver and transfer to the successor Rights Agent any property at
the time held by it hereunder, and execute and deliver any further assurance,
conveyance, act or deed necessary for the purpose. Not later than the effective
date of any such appointment, the Corporation will file notice thereof in
writing with the predecessor Rights Agent and each transfer agent of the Common
Shares and mail a notice thereof in writing to the holders of the Rights in
accordance with Section 5.9. Failure to give any notice provided for in this
Section 4.4, however, or any defect therein, shall not affect the legality or
validity of the resignation or removal of the Rights Agent or the appointment of
any successor Rights Agent, as the case may be.

                           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, determine to 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 Voting Shares
          (which for greater certainty shall not include the circumstances
          described in Subsection 5.1(h)); provided that if the Board of
          Directors waives the application of Section 3.1 to a particular
          Flip-in Event pursuant to this Subsection 5.1(a), the Board of
          Directors shall be deemed to have waived the application of Section
          3.1 to any other Flip-in Event occurring by reason of any Take-over
          Bid which is made by means of a take-over bid circular to all holders
          of Voting Shares prior to the expiry of any Take-over Bid in respect
          of which a waiver is, or is deemed to have been, granted under this
          Subsection 5.1(a).

     (b)  Subject to the prior consent of the holders of the Voting Shares or
          the Rights obtained as set forth in Subsection 5.4(b) or (c), the
          Board of Directors of the Corporation acting in good faith may, at its
          option, at any time prior to the provisions of Section 3.1 becoming
          applicable as a result of the occurrence of a Flip-in Event, elect to
          redeem all but not less than all of the outstanding Rights at a
          redemption price of $0.001 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)  Where a Person acquires pursuant to a Permitted Bid, a Competing
          Permitted Bid or an Exempt Acquisition under Subsection 5.1(a)
          outstanding Voting Shares, other than Voting Shares Beneficially Owned
          at the date of the Permitted Bid, the Competing Permitted Bid or the
          Exempt Acquisition under Subsection 5.1(a) by such Person, then the
          Board of Directors of the Corporation shall immediately upon the
          consummation of such acquisition without further formality and without
          any approval under Subsection 5.4(b) or (c) be deemed to have elected
          to redeem the Rights at the Redemption Price.

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

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


                                     - 35 -


     (f)  Within 10 days after the Board of Directors is deemed under Subsection
          5.1(c) to have elected, or elects under Subsection 5.1(b) or (d), to
          redeem the Rights, the Corporation shall give notice of redemption to
          the holders of the then outstanding Rights by mailing such notice to
          each such holder at his last address as it appears upon the registry
          books of the Rights Agent or, prior to the Separation Time, on the
          registry books of the transfer agent for the Voting Shares. Any notice
          which is mailed in the manner herein provided shall be deemed given,
          whether or not the holder receives the notice. Each such notice of
          redemption will state the method by which the payment of the
          Redemption Price will be made.

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

     (h)  The Board of Directors may waive the application of Section 3.1 in
          respect of the occurrence of any Flip-in Event if the Board of
          Directors has determined within 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(h) must be on the condition
          that such Person, within 14 days after the foregoing determination by
          the Board of Directors or such earlier or later date as the Board of
          Directors may determine (the "Disposition Date"), has reduced its
          Beneficial Ownership of Voting Shares such that the Person is no
          longer an Acquiring Person. If the Person remains an Acquiring Person
          at the close of business on the Disposition Date, the Disposition Date
          shall be deemed to be the date of occurrence of a further Stock
          Acquisition Date and Section 3.1 shall apply thereto.

5.2  EXPIRATION

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

5.3  ISSUANCE OF NEW RIGHTS CERTIFICATES

     Notwithstanding any of the provisions of this Agreement or 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 securities
purchasable upon exercise of Rights made in accordance with the provisions of
this Agreement.

5.4  SUPPLEMENTS AND AMENDMENTS

     (a)  The Corporation may make amendments to this Agreement to correct any
          clerical or typographical error or, subject to Subsection 5.4(e),
          which are required to maintain the validity of this Agreement as a
          result of any change in any applicable legislation, rules or
          regulations thereunder. Notwithstanding anything in this Section 5.4
          to the contrary, no such supplement or amendment shall be made to the
          provisions of Article 4 except with the written concurrence of the
          Rights Agent to such supplement or amendment.

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

     (c)  The Corporation may, with the prior consent of the holders of Rights,
          at any time on or after the Stock Acquisition Date, amend, vary or
          delete any of the provisions of this Agreement and the Rights (whether
          or not such action would materially adversely affect the interests of
          the holders of Rights generally), provided that no such amendment,
          variation or deletion shall be made to the provisions of Article 4
          except with the written concurrence of the Rights Agent thereto. Such
          consent shall be deemed to have been given if such amendment,
          variation or deletion is authorized by the affirmative votes of the
          holders of Rights present or represented at and entitled to be voted
          at a meeting of the holders (such meeting to be called and held in
          compliance with applicable laws and regulatory requirements and, to
          the extent possible, with the requirements in the articles and by-laws
          of the Corporation applicable to meetings of holders of Voting Shares,
          applied MUTATIS MUTANDIS) and representing 50% plus one of the votes
          cast in respect thereof (other than holders of Rights whose Rights
          have become null and void pursuant to Subsection 3.1(b)).

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


                                     - 37 -


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

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

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

          Any such amendment shall be effective from the date of the resolution
          of the Board of Directors adopting such amendment, until it is
          confirmed or rejected or until it ceases to be effective (as described
          in the next sentence) and, where such amendment is confirmed, it
          continues in effect in the form so confirmed. If such amendment is
          rejected by the shareholders or the holders of Rights or is not
          submitted to the shareholders or holders of Rights as required, then
          such amendment shall cease to be effective from and after the
          termination of the meeting at which it was rejected or to which it
          should have been but was not submitted or from and after the date of
          the meeting of holders of Rights that should have been but was not
          held, and no subsequent resolution of the Board of Directors to amend
          this Agreement to substantially the same effect shall be effective
          until confirmed by the shareholders or holders of Rights as the case
          may be.

5.5  FRACTIONAL RIGHTS AND FRACTIONAL SHARES

     (a)  The Corporation shall not be required to issue fractions of Rights or
          to distribute Rights Certificates which evidence fractional Rights.
          After the Separation Time, in lieu of issuing fractional Rights, the
          Corporation shall pay to the holders of record of the Rights
          Certificates (provided the Rights represented by such Rights
          Certificates are not void pursuant to the provisions of Subsection
          3.1(b), at the time such fractional Rights would otherwise be
          issuable), an amount in cash equal to the fraction of the Market Price
          of one whole Right that the fraction of a Right that would otherwise
          be issuable is of one whole Right.

     (b)  The Corporation shall not be required to issue fractions of Common
          Shares upon exercise of Rights or to distribute certificates which
          evidence fractional Common Shares. In lieu of issuing fractional
          Common Shares, the Corporation shall pay to the registered holders of
          Rights Certificates, at the time such Rights are exercised as herein
          provided, an amount in cash equal to the fraction of the Market Price
          of one Common Share that the fraction of a Common Share that would
          otherwise be


                                     - 38 -


          issuable upon the exercise of such Right is of one whole Common Share
          at the date of such exercise.

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 holders of the Rights. Any holder of Rights,
without the consent of the Rights Agent or of the holder of any other Rights,
may, on such holder's own behalf and for such holder's own benefit and the
benefit of other holders of Rights enforce, and may institute and maintain any
suit, action or proceeding against the Corporation to enforce such holder's
right to exercise such holder's Rights, or Rights to which such holder is
entitled, in the manner provided in such holder's Rights 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 limiting the
generality of the foregoing, necessary approvals of The Toronto Stock Exchange
and other exchanges shall be obtained, such as to the issuance of Common Shares
upon the exercise of Rights under Subsection 2.2(d).

5.8  DECLARATION AS TO NON-CANADIAN OR NON-U.S. HOLDERS

     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, the Board of Directors acting in good faith
shall take such actions as it may deem appropriate to ensure such compliance. In
no event shall the 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.

Certificate No. ___________                                  Rights ___________


THE RIGHTS ARE SUBJECT TO TERMINATION ON THE TERMS SET FORTH IN THE SHAREHOLDER
RIGHTS PLAN AGREEMENT. UNDER CERTAIN CIRCUMSTANCES (SPECIFIED IN SUBSECTION
3.1(b) OF THE SHAREHOLDER RIGHTS PLAN AGREEMENT), RIGHTS BENEFICIALLY OWNED BY
AN ACQUIRING PERSON OR CERTAIN RELATED PARTIES, OR TRANSFEREES OF AN ACQUIRING
PERSON OR CERTAIN RELATED PARTIES, MAY BECOME VOID.

                               RIGHTS CERTIFICATE

     This certifies that ________________________________, or 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 Rights Plan Agreement, dated as of
April 24, 2003, as the same may be amended or supplemented from time to time
(the "Shareholder Rights Agreement"), between TransCanada Corporation, a
corporation duly incorporated under the CANADA BUSINESS CORPORATIONS ACT (the
"Corporation") and Computershare Trust Company of Canada, a trust company
incorporated under the laws of Canada (the "Rights Agent") (which term shall
include any successor Rights Agent under the Shareholder Rights Agreement), to
purchase from the Corporation at any time after the Separation Time (as such
term is defined in the Shareholder Rights Agreement) and prior to the Expiration
Time (as such term is defined in the Shareholder 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
with the Form of Election to Exercise (in the form provided hereinafter) duly
executed and submitted to the Rights Agent at its principal office in any of the
cities of Vancouver, Calgary, Regina, Winnipeg, Toronto and Montreal or to the
principal office of The Bank of Montreal Trust Company in New York City, New
York. The Exercise Price shall initially be $100 (Cdn.) per Right and shall be
subject to adjustment in certain events as provided in the Shareholder Rights
Agreement.

     This Rights Certificate is subject to all of the terms and provisions of
the Shareholder Rights Agreement, which terms and provisions are incorporated
herein by reference and made a part hereof and to which Shareholder 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. Copies
of the Shareholder Rights Agreement are on file at the registered office of the
Corporation.


                                     - 2 -


     This Rights Certificate, with or without other Rights Certificates, upon
surrender at any of the offices of the Rights Agent designated for such purpose,
may be exchanged for another Rights Certificate or Rights Certificates of like
tenor and date evidencing an aggregate number of Rights equal to the aggregate
number of Rights evidenced by the Rights Certificate or Rights Certificates
surrendered. If this Rights Certificate shall be exercised in part, the
registered holder shall be entitled to receive, upon surrender hereof, another
Rights Certificate or Rights Certificates for the number of whole Rights not
exercised.

     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 Shareholder Rights Agreement or herein be
