     WHEREAS the Corporation and Montreal Trust Company of Canada entered into
an agreement dated January 25, 1996, as amended and restated on April 15, 1996,
respecting a shareholder rights plan (the "ORIGINAL PLAN") that would be
effective at the latest until the close of business on the date on which the
first annual meeting of the shareholders of the Corporation following the third
anniversary of the date of the Original Plan was held unless a resolution

DIRECTORS") has determined that it is advisable to continue the rights plan by

immediately upon receipt of approval of the Independent Shareholders as defined
in the Prior Plan, to conform to current corporate practices to effect the
continued distribution of Rights under the Prior Plan as further amended and
restated herein (the "RIGHTS PLAN") to ensure, to the extent possible, that all
shareholders of the Corporation are treated fairly in connection with any
take-over offer for the Corporation and, due to the uniqueness of the
Corporation's business, to ensure that the Board of Directors are provided with
a sufficient time to evaluate unsolicited take-over bids and to explore and
develop alternatives to maximize shareholder value;


                                      -2-

     AND WHEREAS, in order to continue implementation of the Rights Plan, the
Board of Directors has:

     (a)  confirmed the distribution of one right (a "RIGHT") in respect of each
          Common Share as hereinafter defined) outstanding at the close of
          business on January 25, 1996 (the "RECORD TIME"), such distribution
          being made to shareholders of record at the Record Time; and

     (b)  reconfirmed its authorization of the issuance of one Right in respect
          of each Common Share issued after the Record Time and prior to the
          earlier of the Separation Time (as hereinafter defined) and the
          Expiration Time (as hereinafter defined);

     AND WHEREAS each Right entitles the holder thereof after the Separation
Time to purchase securities of the Corporation pursuant to the terms and subject
to the conditions set forth herein;

     AND WHEREAS the Corporation desires to confirm its appointment of
Computershare Trust Company of Canada, as successor to Montreal Trust Company of
Canada, as Rights Agent to act on behalf of the Corporation, and the Rights
Agent is willing to continue to so act, in connection with the issuance,
transfer, exchange and replacement of Rights Certificates (as hereinafter
defined), the exercise of Rights and other matters referred to herein;

agreements set forth herein, the parties hereby agree as follows:

          to Exercise (which does not indicate that the holder so exercising is

               designated by such holder; and

          (iv) tender to the Corporation all payments received upon exercise of
               the Rights.

     (f)  In case the holder of any Rights shall exercise less than all the
          Rights evidenced by such holder's Rights Certificate, a new Rights
          Certificate evidencing the Rights remaining unexercised will be issued
          by the Rights Agent to such holder or to such holder's duly authorized
          assigns.

     (g)  The Corporation covenants and agrees that it will:

          (i)  take all such action as may be necessary and within its power to

               of Rights;


                                      -17-

          (iii) use reasonable efforts to cause all shares issued upon exercise
               of Rights to be listed on the principal exchanges or traded in
               the over-the-counter markets on which the Common Shares were
               traded immediately prior to the Stock Acquisition Date;

               holder or exercising holder or any liability of the Corporation
               to withhold tax) and charges which may be payable in respect of
               the original issuance or delivery of the Rights Certificates or
               certificates for shares, 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 shares in a name other than that of the holder
               of the Rights being transferred or exercised.

2.3  ADJUSTMENTS TO EXERCISE PRICE; NUMBER OF RIGHTS

     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)  In the event the Corporation shall at any time after the Amendment
          Date and prior to the Expiration Time:

          (i)  declare or pay a dividend on the Common Shares payable in Voting
               Shares (or other capital stock or securities exchangeable for or
               convertible into or giving a right to acquire Voting Shares or
               other capital stock) other than pursuant to any optional stock
               dividend program, dividend reinvestment plan or a dividend
               payable in Voting Shares in lieu of a regular periodic cash
               dividend;

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

          (iii) combine or change the then outstanding Common Shares into a
               smaller number of Common Shares; or

          (iv) issue any Voting Shares (or other capital stock or securities
               exchangeable for or convertible into or giving a right to acquire
               Voting Shares or other capital stock) in respect of, in lieu of
               or in exchange for existing Common Shares in a reclassification,
               amalgamation, merger, statutory arrangement or consolidation,

          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 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


                                      -18-

          such adjustment shall 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 (y) each Right held prior to such adjustment shall become
          that number of Rights equal to the Expansion Factor, and the adjusted
          number of Rights will be deemed to be allocated 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. 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 number of 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
          Amendment Date 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 appropriate under the
          circumstances and the Corporation and the Rights Agent agree to amend
          this Agreement in order to effect such treatment. If an event occurs
          which would require an adjustment under both this Section 2.3 and
          Section 3.1 hereof, 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 hereof. Adjustments pursuant to
          subsection 2.3(a) shall be made successively, whenever an event
          referred to in subsection 2.3(a) occurs.

          In the event the Corporation shall at any time after the Amendment
          Date and prior to the Separation Time issue any Common Shares
          otherwise than in a transaction referred to in the preceding
          paragraph, 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 Common Share. Notwithstanding
          anything else in this subsection 2.3(a), the Exercise Price shall not
          be adjusted to give effect to the two-for-one stock split submitted to
          the Corporation's shareholders for approval at the 2002 annual general
          meeting of the Corporation's shareholders.

     (b)  In the event the Corporation shall at any time after the Amendment
          Date and prior to the Expiration Time fix a record date for the making
          of a distribution to all holders of Common Shares of rights or
          warrants 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 or subscribe for Voting 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 Voting Shares, having a conversion,
          exchange or exercise price (including the price required to be paid to
          purchase such convertible or exchangeable security or right per
          share)) less than 90% of the Market Price per Common Share on such
          record date, the Exercise Price shall be adjusted in the manner set
          forth below. The Exercise Price in effect after such record date shall
          equal the Exercise Price in effect immediately prior to such record
          date multiplied by a fraction, of which the numerator shall be the
          number of Common Shares outstanding on such record date plus the
          number of Common Shares which 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


                                      -19-

          to purchase such convertible or exchangeable securities or rights))
          would purchase at such Market Price and of which the denominator 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 is satisfied in whole or
          in part by consideration 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. For purposes of this paragraph (b), the granting of the
          right to purchase Common Shares pursuant to any dividend or interest
          reinvestment 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 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 or
          interest reinvestment plan, the right to purchase Common Shares is at
          a price per share of not less than 90% of the current market price per
          share (determined as provided in such plans) of the Common Shares.

     (c)  In the event the Corporation shall at any time after the Amendment
          Date and prior to the Expiration Time fix a record date for the making
          of a distribution to all holders of Common Shares of evidences of
          indebtedness or assets (other than a regular periodic cash dividend or
          a dividend paid in Common Shares ) or rights or warrants entitling
          them to subscribe for or purchase Voting Shares (or Convertible
          Securities in respect of Voting Shares) at a price per Voting Share
          (or, in the case of a Convertible Security in respect of Voting Shares
          having a conversion or exercise price per share (including the price
          required to be paid to purchase such Convertible Security) less than
          90% of the Market Price per Common Share on such record date
          (excluding those referred to in subsection 2.3(b)), the Exercise Price
          shall be adjusted in the manner set forth below. The Exercise Price in
          effect after such record date shall equal the Exercise Price in effect
          immediately prior to such record date less the fair market value (as
          determined in good faith by the Board of Directors) of the portion of
          the assets, evidences of indebtedness, rights or warrants so to be
          distributed applicable to each of the securities purchasable upon
          exercise of one Right (such determination to be described in a
          statement filed with the Rights Agent and the holders of the Rights).
          Such adjustment shall be made successively whenever such a record date
          is 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 paragraph (a) above; and

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


                                      -20-

     (e)  In the event the Corporation shall at any time after the Amendment
          Date and prior to the Expiration 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 clause (a)(i) or (a)(iv) above, or if the Corporation shall take
          any other action (other than the issue of Common Shares) which might
          have a negative effect on the holders of Rights, if the Board of
          Directors acting in good faith determines that the adjustments
          contemplated by paragraphs (a), (b) and (c) above are not applicable
          or will not appropriately protect the interests of the holders of
          Rights, the Corporation may determine what other adjustments to the
          Exercise Price, number of Rights and/or securities purchasable upon
          exercise of Rights would be appropriate and, if the adjustments
          contemplated by paragraphs (a), (b) and (c) above are applicable,
          notwithstanding such paragraphs, the adjustments so determined by the
          Corporation, rather than adjustments contemplated by paragraphs (a),
          (b) and (c) above, shall be made. The Corporation and the Rights Agent
          shall amend this Agreement in accordance with subsections 5.4(b) and
          5.4(c), as the case may be, to provide for such adjustments.

     (f)  Each adjustment to the Exercise Price made pursuant to this Section
          2.3 shall be calculated to the nearest cent. 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;
               and

          (ii) promptly file with the Rights Agent and with each transfer agent
               for the Common Shares a copy of such certificate and mail a brief
               summary thereof to each holder of Rights who requests a copy.

          Failure to file such certificate or cause such summary to be mailed as
          aforesaid, or any defect therein, shall not affect the validity of any
          such adjustment or change.

     (g)  Irrespective of any adjustment or change in the securities purchasable
          upon exercise of the Rights, the Rights Certificates theretofore and
          thereafter issued may continue to express the securities so
          purchasable which were expressed in the initial Rights Certificates
          issued hereunder.

2.4  DATE ON WHICH EXERCISE IS EFFECTIVE

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


                                      -21-

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, Chief Executive Officer,
          Chief Financial Officer or any Vice President. 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.
          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 a disclosure statement
          describing the Rights, and the Rights Agent shall countersign
          (manually or by facsimile signature) and mail such Rights Certificates
          and disclosure statement 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.

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

2.6  REGISTRATION, REGISTRATION OF 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 "RIGHTS
          REGISTRAR" for the purpose of maintaining the Rights Register for the
          Corporation and registering Rights and transfers of Rights as herein
          provided. In the event that the Rights Agent shall cease to be the
          Rights Registrar, the Rights Agent will have the right to examine the
          Rights Register at all reasonable times.

     (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 subsection 2.6(d) below,
          the Corporation shall execute, and the Rights Agent shall countersign
          and deliver, in the name of the holder or the designated transferee or
          transferees, as required pursuant to the holder's instructions, one or
          more new Rights Certificates evidencing the same aggregate number of
          Rights as did the Rights 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.


                                      -22-

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 satisfaction of the
          destruction, loss or theft of any Rights Certificate and (ii) such
          security or indemnity as may be required by 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 its request the
          Rights Agent shall countersign and deliver, in lieu of any such
          destroyed, lost or stolen Rights Certificate, a new Rights Certificate
          evidencing the same number of Rights as did the Rights Certificate so
          destroyed, lost or stolen.

     (c)  As a condition to the issuance of any new Rights Certificate under
          this Section 2.7, the 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 an original additional 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

     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.

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


                                      -23-

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 that:

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

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

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

     (d)  prior to due presentment of a Rights Certificate (or, prior to the
          Separation Time, the associated Common Share certificate) for
          registration of transfer, 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)  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)  without the approval of any holder of Rights and upon the sole
          authority of the Board of Directors acting in good faith this
          Agreement may be supplemented or amended from time to time as provided
          herein; and

     (g)  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 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.

     (a)  Subject to subsections 3.1(b), 5.1(b), 5.1(c) and 5.1(d) hereof, in
          the event that prior to the Expiration Time a Flip-in Event shall
          occur, the Corporation shall take such action as shall be necessary to
          ensure and provide, within 10 Business Days thereafter or such longer
          period as may be required to satisfy the requirements of the
          applicable securities acts or comparable legislation so that, except
          as provided below, each Right shall thereafter constitute the right to
          purchase from the Corporation, upon exercise thereof in


                                      -24-

          accordance with the terms hereof, that number of Common Shares of the
          Corporation 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 date of consummation or occurrence an event of a type
          analogous to any of the events described in Section 2.3 shall have
          occurred with respect to such Common Shares).

     (b)  Notwithstanding the foregoing or any other provisions of this
          Agreement, 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, direct or indirect, 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) in a transfer made
               after the date hereof, whether or not for consideration, that the
               Board of Directors acting in good faith 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 any Acquiring Person or any
               Affiliate or Associate of an Acquiring Person) that has the
               purpose or effect of avoiding clause (i) of this subsection
               3.1(b),

          shall become void and any holder of such Rights (including
          transferees) shall thereafter have no right, to exercise such Rights
          under any provision of this Agreement and shall not have any other
          rights whatsoever in respect of such Rights, whether under any
          provision of this Agreement or otherwise.

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

               "The Rights represented by this Rights Certificate were
               Beneficially Owned by a Person who was an Acquiring Person
               or who was an Affiliate or an Associate of an Acquiring
               Person (as such terms are defined in the Rights Agreement)
               or was acting jointly or in concert with any of them. This
               Rights Certificate and the Rights represented hereby shall
               become 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 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 an Acquiring Person, an Affiliate
          or Associate thereof or a Person acting jointly or in concert with any
          of them.

                                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 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 (the "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 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 reasonably incurred in the execution and administration
          of this Agreement and the exercise and performance of its duties
          hereunder (including the reasonable fees and other disbursements of
          any expert retained by the Rights Agent with the approval of the
          Corporation, such approval not to be unreasonably withheld). The
          Corporation also agrees to indemnify the Rights Agent, its directors,
          officers, employees and agents for, and to hold them harmless against,
          any loss, liability, cost, claim, action, damage or expense, incurred
          without negligence, bad faith or wilful misconduct on the part of the
          Rights Agent or its directors, officers, employees and agents, for
          anything done, suffered or omitted by the Rights Agent in connection
          with the acceptance, execution and administration of this Agreement
          and the exercise and performance of its duties hereunder, including
          the costs and expenses of defending against any claim of liability,
          which right to indemnification will survive the termination of this
          Agreement or the resignation or removal of the Rights Agent.

     (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 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 or consolidation to which the Rights Agent or any
          successor Rights Agent is a party or any corporation succeeding to the
          shareholder or stockholder services business of the Rights Agent or
          any successor Rights Agent, will be the successor to the Rights Agent
          under this Agreement without the execution or filing of any paper or
          any further act on the part of any of the parties hereto, provided
          that such corporation would be eligible for appointment as a successor
          Rights Agent under the provisions of Section 4.4 hereof. In case, at
          the time such successor Rights Agent succeeds to the agency created by
          this Agreement, any of the Rights Certificates have been countersigned
          but not delivered, any such successor Rights Agent may adopt the
          countersignature of the predecessor Rights Agent and deliver such
          Rights Certificates so


                                      -26-

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

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

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 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; the Rights Agent may also, with the approval of the
          Corporation (such approval not to be unreasonably withheld) and at the
          expense of the Corporation, 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 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, Chief Executive Officer, Chief Financial
          Officer or any Vice President 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 negligence,
          bad faith or wilful misconduct.

     (d)  The Rights Agent will not be liable for or by reason of any of the
          statements of fact or recitals contained in this Agreement or in the
          certificates for Common Shares or the Rights Certificates (except its
          countersignature thereof) or be required to verify the same, but all
          such statements and recitals are and will be deemed to have been made
          by the Corporation only.


                                      -27-

     (e)  The Rights Agent will not be under any responsibility in respect of
          the validity of this Agreement or the execution and delivery hereof
          (except the due authorization, execution and delivery hereof by the
          Rights Agent) or in respect of the validity or execution of any Common
          Share certificate or Rights Certificate (except its countersignature
          thereof); nor will it be responsible for any breach by the 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) 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 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, the Chief Executive Officer, the Chief Financial
          Officer or any Vice President, and to apply to such persons for advice
          or instructions in connection with its duties, and it shall not be
          liable for any action taken or suffered by it in good faith in
          reliance upon instructions of any such person; it is understood that
          instructions to the Rights Agent shall, except where circumstances
          make it impracticable or the Rights Agent otherwise agrees, be given
          in writing and, where not in writing, such instructions shall be
          confirmed in writing as soon as reasonably possible after the giving
          of such instructions.

     (h)  The Rights Agent and any shareholder or stockholder, director, officer
          or employee of the Rights Agent may buy, sell or deal in Common
          Shares, Rights or other securities of the 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.

     (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, omission, default, neglect or
          misconduct of any such attorneys or agents or for any loss to the
          Corporation resulting from any such act, omission, default, neglect or
          misconduct, provided reasonable care was exercised in the selection
          and continued employment thereof.


                                      -28-

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, and to the holders of the Rights
in accordance with Section 5.9. The Corporation may remove the Rights Agent upon
30 days' notice in writing given to the Rights Agent and to each transfer agent
of the Common Shares (by personal delivery, or 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 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 or any 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 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 upon payment of its outstanding fees and expenses
owing by the Corporation to the predecessor Rights Agent under this Agreement,
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. 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.

                                  MISCELLANEOUS

5.1  REDEMPTION AND TERMINATION

     (a)  The Board of Directors acting in good faith may, with the prior
          consent of holders of Voting Shares or of the holders of Rights given
          in accordance with subsection 5.1(f) or (g), as the case may be, at
          any time prior to the occurrence of a Flip-in Event as to which the
          application of Section 3.1 has not been waived pursuant to the
          provisions of this Section 5.1, 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 in the event that 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").

     (b)  The Board of Directors acting in good faith may, with the prior
          consent of the holders of Voting Shares given in accordance with
          subsection 5.1(f), determine, at any time prior to the occurrence of a
          Flip-in Event as to which the application of Section 3.1 has not been
          waived pursuant to this Section 5.1, if such Flip-in Event would occur
          by reason of an acquisition of Voting Shares otherwise than pursuant
          to a Take-over Bid made by means of a Take-over Bid circular to all
          holders of record of Voting Shares and otherwise than in the
          circumstances set forth in subsection 5.1(d), to waive the application
          of Section 3.1 to such Flip-in Event. In the event that the Board of
          Directors proposes such a waiver, the Board of Directors shall extend
          the Separation Time to a date subsequent to and not


                                      -29-

          more than ten Business Days following the meeting of shareholders
          called to approve such waiver.

     (c)  The Board of Directors acting in good faith may, prior to the
          occurrence of a Flip-in Event as to which the application of Section
          3.1 has not been waived under this clause, determine, upon prior
          written notice to the Rights Agent, to waive the application of
          Section 3.1 to that Flip-in Event provided that the Flip-in Event
          would occur by reason of a Take-over Bid made by means of a Take-over
          Bid circular sent to all holders of record of Voting Shares; further
          provided that if the Board waives the application of Section 3.1 to
          such a Flip-in Event, the Board of Directors shall be deemed to have
          waived the application of Section 3.1 to any other Flip-in Event
          occurring by reason of any Take-over Bid made by means of a Take-over
          Bid circular to all holders of record of Voting Shares which is made
          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(c).

     (d)  The Board of Directors acting in good faith may, in respect of any
          Flip-in Event waive the application of Section 3.1 to that Flip-in
          Event, provided that both of the following conditions are satisfied:

          (i)  the Board of Directors has determined that the Acquiring Person
               became an Acquiring Person by inadvertence and without any intent
               or knowledge that it would become an Acquiring Person; and

          (ii) such Acquiring Person has reduced its Beneficial Ownership of
               Voting Shares such that at the time of waiver pursuant to this
               subsection 5.1(d) it is no longer an Acquiring Person.

     (e)  The Board of Directors shall, without further formality, be deemed to
          have elected to redeem the Rights at the Redemption Price on the date
          that a Person who has made a Permitted Bid or a Take-over Bid in
          respect of which the Board of Directors has waived, or is deemed to
          have waived, pursuant to subsection 5.1(c), the application of Section
          3.1, takes up and pays for the Voting Shares pursuant to the terms and
          conditions of the Permitted Bid or Take-over Bid, as the case may be.

     (f)  If a redemption of Rights pursuant to subsection 5.1(a) or a waiver of
          a Flip-in Event pursuant to subsection 5.1(b) is proposed at any time
          prior to the Separation Time, such redemption or waiver shall be
          submitted for approval to the holders of Voting Shares. Such approval
          shall be deemed to have been given if the redemption or waiver is
          approved by the affirmative vote of a majority of the votes cast by
          Independent Shareholders represented in person or by proxy at a
          meeting of such holders duly held in accordance with applicable laws
          and the Corporation's by-laws.

     (g)  If a redemption of Rights pursuant to subsection 5.1(a) is proposed at
          any time after the Separation Time, such redemption shall be submitted
          for approval to the holders of Rights. Such approval shall be deemed
          to have been given if the redemption is approved by holders of Rights
          by a majority of the votes cast by the holders of Rights represented
          in person or by proxy at and entitled to vote at a meeting of such
          holders. For the purposes hereof, each outstanding Right (other than
          Rights which are Beneficially Owned by any Person referred to in
          clauses (i) to (v) inclusive of the definition of Independent
          Shareholders) 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


                                      -30-

          Corporation's by-laws and the BUSINESS CORPORATIONS ACT with respect
          to meetings of shareholders of the Corporation.

     (h)  Where a Take-over Bid that is not a Permitted Bid is withdrawn or
          otherwise terminated after the Separation Time has occurred and prior
          to the occurrence of a Flip-in Event, the Board may elect to redeem
          all the outstanding Rights at the Redemption Price. Notwithstanding
          such redemption, all of the provisions of this Agreement shall
          continue to apply as if the Separation Time had not occurred and it
          shall be deemed not to have occurred and Rights shall remain attached
          to the outstanding Common Shares, subject to and in accordance with
          the provisions of this Agreement.

     (i)  If the Board of Directors elects or is deemed to have elected to
          redeem the Rights, and, in circumstances where subsection 5.1(a) is
          applicable, such redemption is approved by the holders of Voting
          Shares or the holders of Rights in accordance with subsection 5.1(f)
          or (g), as the case may be, 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 will be to receive
          the Redemption Price.

     (j)  Within 10 Business Days of the Board of Directors electing or having
          been deemed to have elected to redeem the Rights or, if subsection
          5.1(a) is applicable within 10 Business Days after the holders of
          Voting Shares or the holders of Rights have approved a redemption of
          Rights in accordance with subsection 5.1(f) or (g), as the case may
          be, the Corporation shall give notice of redemption to the holders of
          the then outstanding Rights by mailing such notice to each such holder
          at its last address as it appears upon the register of the Rights
          Agent or, prior to the Separation Time, on the register of the
          transfer agent for the Common Shares. Any notice which is mailed in
          the manner herein provided will 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.
          The Corporation may not redeem, acquire or purchase for value any
          Rights at any time in any manner other than that specifically set
          forth in this Section 5.1 or in connection with the purchase of Common
          Shares prior to the Separation Time.

     (k)  The Corporation shall give prompt written notice to the Rights Agent
          of any waiver of the application of Section 3.1 made by the Board of
          Directors under this Section 5.1.

5.2  EXPIRATION

     No Person shall have any rights 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 of the Rights to
the contrary, the Corporation may, at the option, issue new Rights Certificates
evidencing Rights in such form as may be approved by its Board of Directors to
reflect any adjustment or change in the number of 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)  The Corporation may make amendments to this Agreement to correct any
          clerical or typographical error or which are required to maintain the
          validity of this Agreement as a


                                      -31-

          result of any change in any applicable legislation, rules or
          regulations thereunder. The Corporation may, prior to the date of the
          shareholders' meeting referred to in Section 5.18, supplement, amend,
          vary, rescind or delete any of the provisions of this Agreement
          without the approval of any holders of Rights or Voting Shares
          (whether or not such action would materially adversely affect the
          interests of the holders of Rights generally) where the Board of
          Directors acting in good faith deems such action necessary or
          desirable. Notwithstanding anything in this Section 5.4 to the
          contrary, no such supplement or amendment shall be made to the
          provisions of Article 4 except with the written concurrence of the
          Rights Agents to such supplement or amendment.

     (b)  Subject to subsection 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, supplement, amend, vary,
          rescind 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). 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 Separation Time, supplement, amend, vary,
          rescind 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 held in accordance with
          subsection 5.4(d) and representing 50% plus one of the votes cast in
          respect thereof.

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

     (e)  Any amendments made by the Corporation to this Agreement pursuant to
          subsection 5.4(a) which are required to maintain the validity of this
          Agreement as a result of any change in any applicable legislation,
          rules 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


                                      -32-

               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.

     (f)  The Corporation shall be required to provide the Rights Agent with
          notice in writing of any such amendment, recission or variation to
          this Agreement as referred to in this Section 5.4 within five days of
          effecting such amendment, recission or variation.

     (g)  Any supplement or amendment to this Agreement pursuant to subsections
          5.4(b) through (e) shall be subject to the receipt of any requisite
          approval or consent from any governmental or regulatory authority
          having jurisdiction over the Corporation, including without limitation
          any requisite approval of stock exchanges on which the Common Shares
          are listed.

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 there shall be paid to the registered
          holders of the Rights Certificates with regard to which fractional
          Rights would otherwise be issuable, an amount in cash equal to the
          same fraction of the Market Price of a whole Right in lieu of such
          fractional Rights as of the date such fractional Rights would
          otherwise be issuable. The Rights Agent shall have no obligation to
          make any payments in lieu of fractional Rights unless the Corporation
          shall have provided the Rights Agent with the necessary funds to pay
          in full all amounts payable in accordance with subsection 2.2(e).

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

5.6  RIGHTS OF ACTION

     Subject to the terms of this Agreement, rights of action in respect of this
Agreement, other than rights of action vested solely in the Rights Agent, are
vested in the respective holders of the Rights; and any holder of any Rights,
without the consent of the Rights Agent or of the holder of any other Rights,
may, on such holder's own behalf and for such holder's own, benefit and the
benefit of other holders of


                                      -33-

Rights, enforce, and may institute and maintain any suit, action or proceeding
against the Corporation to enforce, or otherwise act in respect of, such
holder's right to exercise such holder's Rights, or Rights to which he is
entitled, in the manner provided in this Agreement and in such holder's Rights
Certificate. 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  HOLDER OF RIGHTS NOT DEEMED A SHAREHOLDER

     No holder, as such, of any Rights shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of Common Shares or any other
securities which may at any time be issuable on the exercise of Rights, nor
shall anything contained herein or in any Rights Certificate be construed to
confer upon the holder of any Rights, 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 Section
5.8 hereof), or to receive dividends or subscription rights or otherwise, until
such Rights, or Rights to which such holder is entitled, shall have been
exercised in accordance with the provisions hereof.

5.8  NOTICE OF PROPOSED ACTIONS

     In case the Corporation shall propose after the Separation Time and prior
to the Expiration Time:

     (a)  to effect or permit (in cases where the Corporation's permission is
          required) any Flip-in Event; or

     (b)  to effect the liquidation, dissolution or winding up of the
          Corporation or the sale of all or substantially all of the
          Corporation's assets,

then, in each such case, the Corporation shall give to each holder of a Right,
in accordance with Section 5.9 hereof, a notice of such proposed action, which

winding up is to take place, and such notice shall be so given at least 10
Business Days prior to the date of taking of such proposed action by the
Corporation.

of shareholders of the Corporation terminates, then the Prior Plan and this

further force and effect on and from that date which is the earlier of (a) the

of this Agreement to the Independent Shareholders for their consideration and,
if thought advisable, approval. Unless the majority of the votes cast by
Independent Shareholders who vote in respect of such resolution are voted in
favour of the continued existence of this Agreement, the Board of Directors
shall, immediately upon the confirmation by the Chairman of such shareholders'
meeting of the results of the votes on such resolution and without further
formality, be deemed to elect to redeem the Rights at the Redemption Price.

5.21 Declaration as to Non-Canadian and Non-U.S. Holders

of counsel), any action or event contemplated by this Agreement would require
compliance with the securities laws or comparable legislation of a jurisdiction
outside Canada and the United States of America, its territories and
possessions, the Board of Directors acting in good faith may 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 resident Fiduciary of Rights or securities issuable on exercise of
Rights, the holding thereof in trust for the Persons entitled thereto (but
reserving to the Fiduciary or to the Fiduciary and the Corporation, as the
Corporation may determine, absolute discretion with respect thereto) and the
sale thereof and remittance of the 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 and a province or territory thereof and the United States of America
and any state thereof in which such issue or delivery would be unlawful without
registration of the relevant Persons or securities for such purposes.

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,

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
