WHEREAS:

A.   The Board of Directors has determined that it is advisable to adopt a

     possible, that all shareholders of the Corporation are treated fairly in
     connection with any takeover offer for the Corporation or other acquisition
     of control of the Corporation.

B.   In order to implement the Rights Plan, the Board of Directors has:

     (a)  authorized and declared a distribution of one right (a "Right")
          effective at the Close of Business at the Record Time in respect of
          each Common Share outstanding at the Close of Business at the Record
          Time;

     (b)  authorized 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 and the Expiration Time; and

     (c)  authorized the issuance of Rights Certificates to holders of Rights
          pursuant to the terms and subject to the conditions set forth herein.

C.   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.

D.   The Corporation desires to appoint the Rights Agent to act on behalf of the
     Corporation, and the Rights Agent is willing to so act, in connection with
     the issuance, transfer, exchange and replacement of Rights Certificates,
     the exercise of Rights and other matters referred to herein.

     NOW THEREFORE in consideration of the premises and respective agreements
set forth herein, the parties hereby agree as follows:

               shall, after the


                                      -2-

               Record Time: (1) cease to own 20% or more of the outstanding

1.6  DETERMINATION OF PERCENTAGE OWNERSHIP

     The percentage of Voting Shares Beneficially Owned by any Person, shall,
for the purposes of this Agreement, be and be deemed to be the product
determined by the formula:

            A
     100 x ---
            B

     where:

     A =  the aggregate number of votes for the election of all directors
          generally attaching to the Voting Shares Beneficially Owned by such
          Person; and

     B =  the aggregate number of votes for the election of all directors
          generally attaching to all outstanding Voting Shares.

     For the purposes of the foregoing formula, where any Person is deemed to
Beneficially Own unissued Voting Shares which may be acquired pursuant to
Convertible Securities, such Voting Shares shall be deemed to be outstanding for
the purpose of calculating the percentage of Voting Shares Beneficially Owned by
such Person in both the numerator and the denominator, but no other unissued
Voting Shares which may be acquired pursuant to any other outstanding
Convertible Securities shall, for the purposes of that calculation, be deemed to
be outstanding.

                                   THE RIGHTS

2.1  LEGEND ON COMMON SHARE CERTIFICATES

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

               "Until the Separation Time (as defined in the Rights Agreement
               referred to below), this certificate also evidences and entitles
               the holder hereof to certain Rights as set forth in a Shareholder
               Rights Plan Agreement, dated as of April ___, 2005 (the "Rights
               Agreement"), between the Corporation and Computershare Trust
               Company of Canada, as Rights Agent, the terms of which are hereby
               incorporated herein by reference and a copy of which is on file
               at the registered office of the Corporation. Under certain
               circumstances, as set forth in the Rights Agreement, such Rights
               may be amended or redeemed, may expire, may become void (if, in
               certain cases, they are "Beneficially Owned" by an "Acquiring
               Person", as such terms are defined in the Rights Agreement, or a
               transferee thereof) or may be evidenced by separate certificates
               and may no longer be evidenced by this certificate. The
               Corporation will mail or arrange for the mailing of a copy of the
               Rights Agreement to the holder of this certificate without charge
               as soon as practicable after the receipt of a written request
               therefor."

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

2.2  INITIAL EXERCISE PRICE; EXERCISE OF RIGHTS; DETACHMENT OF RIGHTS

     (a)  Subject to adjustment as herein set forth including, without
          limitation, as set forth in Article 3, each Right will entitle the
          holder thereof, from and after the Separation Time and prior to the
          Expiration Time, to purchase one Common Share for the Exercise Price,
          or its U.S. Dollar Equivalent, as at the Business Day immediately
          preceding the Separation Time (which Exercise Price and number of
          Common Shares are subject to adjustment as set forth below).
          Notwithstanding any other provision of this Agreement, any Rights held
          by the Corporation or any of its subsidiaries shall be void.

     (b)  Until the Separation Time, (i) the Rights shall not be exercisable and
          no Right may be exercised and (ii) for administrative purposes, each
          Right will be evidenced by the certificate for the associated Common
          Share registered in the name of the holder thereof (which certificate
          shall be deemed to represent a Rights Certificate) and will be
          transferable only together with, and will be transferred by a transfer
          of, such associated Common Share.

     (c)  From and after the Separation Time and prior to the Expiration Time,
          the Rights may be exercised, and the registration and transfer of the
          Rights shall be separate from and


                                      -15-

          independent of Common Shares. Promptly following the Separation Time,
          the Corporation will prepare or cause to be prepared and the Rights
          Agent will mail to each holder of record of Common Shares as of the
          Separation Time and, in respect of each Convertible Security converted
          into Common Shares after the Separation Time and prior to the
          Expiration Time, promptly after such conversion, the Corporation will
          prepare or cause to be prepared and the Rights Agent will mail to the
          holder so converting (other than an Acquiring Person and in respect of
          any Rights Beneficially Owned by such Acquiring Person which are not
          held of record by such Acquiring Person, the holder of record of such
          Rights (a "Nominee")) at such holder's address as shown by the records
          of the Corporation (the Corporation hereby agreeing to furnish copies
          of such record to the Rights Agent for this purpose):

          (i)  a Rights Certificate in substantially the form of Exhibit A
               hereto appropriately completed, representing the number of Rights
               held by such holder at the Separation Time and having such marks
               of identification or designation and such legends, summaries or
               endorsements printed thereon as the Corporation may deem
               appropriate and as are not inconsistent with the provisions of
               this Agreement, or as may be required to comply with any law,
               rule or regulation or judicial or administrative order, or with
               any article or regulation of any stock exchange or quotation
               system on which the Rights may from time to time be listed or
               traded, or to conform to usage; and

          (ii) a disclosure statement prepared by the Corporation describing the
               Rights, provided that a Nominee shall be sent the materials
               provided for in (i) and (ii) only in respect of all Common Shares
               held of record by it which are not Beneficially Owned by an
               Acquiring Person and the Corporation may require any Nominee or
               suspected Nominee to provide such information and documentation
               as the Corporation may reasonably require for such purpose.

     (d)  Rights may be exercised in whole or in part on any Business Day after
          the Separation Time and prior to the Expiration Time by submitting to
          the Rights Agent, at its principal office in Toronto or any other
          office of the Rights Agent designated for that purpose from time to
          time by the Corporation:

          (i)  the Rights Certificate evidencing such Rights;

          (ii) an election to exercise (an "Election to Exercise") substantially
               in the form attached to the Rights Certificate duly completed,
               and executed in a manner acceptable to the Rights Agent; and

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

     (e)  Upon receipt of a Rights Certificate, which is accompanied by an
          appropriately completed and duly executed Election to Exercise (which
          does not indicate that such Right is null and void as provided by
          Subsection 3.1(b)) and payment as set forth in Subsection 2.2(d), the
          Rights


                                      -16-

          Agent (unless otherwise instructed by the Corporation) will thereupon
          promptly:

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

          (ii) after receipt of such Common Share certificates, deliver such
               certificates to, or to the order of, the registered holder of
               such Rights Certificate, registered in such name or names as may
               be designated by such holder;

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

          (iv) when appropriate, after receipt of such cash, deliver such cash
               to, or to the order of, the registered holder of the Rights
               Certificate; and

          (v)  tender to the Corporation all payments received on exercise of
               the Rights.

     (f)  If 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 subject to
          subsection 5.5(a) will be issued by the Rights Agent to such holder or
          to such holder's duly authorized assigns.

     (g)  The Corporation shall:

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

          (ii) take all such action as may reasonably be considered to be
               necessary and within its power to comply with any applicable
               requirements of the Business Corporations Act or the Securities
               Act, the U.S. Exchange Act, the United States Securities Act of
               1933, as amended, and comparable legislation of each of the
               provinces and territories of Canada and states of the United
               States of America, or the rules and regulations thereunder or any
               other applicable law, rule or regulation, in connection with the
               issuance and delivery of the Rights, the Rights Certificates and
               the issuance of any Common Shares upon exercise of the Rights;

          (iii) use reasonable efforts to cause all Common Shares issued upon
               exercise of the Rights to be listed on the stock exchanges on
               which the Common Shares are listed at that time;

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


                                      -17-

          (v)  pay when due and payable, if applicable, any and all federal,
               provincial, state and municipal taxes (not in the nature of
               income, capital gains or withholding taxes) and charges which may
               be payable in respect of the original issuance or delivery of the
               Rights Certificates or certificates for Common Shares issued upon
               the exercise of 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 of Rights or the issuance or
               delivery of certificates for Common Shares issued upon the
               exercise of Rights, in a name other than that of the holder of
               the Rights being transferred or exercised; and

          (vi) after the Separation Time, except as permitted by Section 5.1 or
               Section 5.4 hereof, not take (or permit any Affiliate of the
               Corporation to take) any action if at the time such action is
               taken it is reasonably foreseeable that such action will diminish
               substantially or otherwise eliminate the benefits intended to be
               afforded by the Rights.

2.3  ADJUSTMENTS TO EXERCISE PRICE; NUMBER OF RIGHTS

     (a)  The Exercise Price, the number and kind of securities subject to
          purchase upon exercise of each Right and the number of Rights
          outstanding are subject to adjustment from time to time as provided in
          this Section 2.3 and in Article 3.

     (b)  In the event that the Corporation shall at any time after the Record
          Time and prior to the Expiration Time:

          (i)  declare or pay a dividend on the Common Shares payable in Voting
               Shares or Convertible Securities in respect thereof other than
               pursuant to any dividend reinvestment plan;

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

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

          (iv) issue any Voting Shares (or Convertible Securities in respect
               thereof) in respect of, in lieu of or in exchange for existing
               Common Shares, whether in a reclassification, amalgamation,
               statutory arrangement, consolidation or otherwise;

          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 the exercise of Rights) shall be
          adjusted as follows:

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

                    1)   the Exercise Price in effect after such adjustment will
                         be equal to the Exercise Price in effect immediately
                         prior to such adjustment divided by the number of
                         Common Shares (or other securities of the Corporation)
                         (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


                                      -18-

                    2)   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
                         allocated among the Common Shares with respect to which
                         the original Rights were associated (if they remain
                         outstanding) and the securities of the Corporation
                         issued in respect of such dividend, subdivision,
                         change, consolidation or issuance, so that each such
                         Common Share (or other security of the Corporation)
                         will have exactly one Right associated with it.

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

     (c)  Adjustments pursuant to Subsection 2.3(b) shall be made successively,
          whenever an event referred to in Subsection 2.3(b) occurs.

     (d)  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.

     (e)  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 Subsection 2.3(b), 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.

     (f)  In the event the Corporation shall, at any time after the Record Time
          and prior to the Expiration Time, fix a record date for the making of
          a distribution to all holders of Common Shares 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
          Convertible Securities in respect of Common Shares) at a price per
          Common Share (or, in the case of such a Convertible Security, having a
          conversion, exchange 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, the
          Exercise Price in effect after such record date will equal the
          Exercise Price in effect immediately prior to such record date
          multiplied by a fraction;

          (i)  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 Securities so to be
               offered (including the price required to be paid to purchase such
               Convertible Securities)) would purchase at such Market Price per
               Common Share; and

          (ii) 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 Securities so to be offered are


                                      -19-

               initially convertible, exchangeable or exercisable).

          In case such subscription price is satisfied, in whole or in part, by
          consideration other than cash, the value of such consideration shall
          be as determined in good faith by the Board of Directors. Such
          adjustment shall be made successively whenever such a record date is
          fixed. To the extent that such rights or warrants are not exercised
          prior to the expiration thereof, the Exercise Price shall be
          readjusted in the manner contemplated above based on the number of
          Common Shares (or securities convertible into or exchangeable for
          Common Shares) actually issued on the exercise of such rights or
          warrants.

          For purposes of this Agreement, the granting of the right to purchase
          Common Shares (whether from treasury or otherwise) pursuant to any
          dividend or interest reinvestment plan or any share purchase plan
          providing for the reinvestment of dividends or interest payable on
          securities of the Corporation or the investment of periodic optional
          payments 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 by the Corporation) 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 or share
          purchase 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.

     (g)  In the event the Corporation shall at any time after the Record Time
          and prior to the Expiration Time fix a record date for the making of a
          distribution to all holders of Common Shares of (i) evidences of
          indebtedness or assets (other than a Regular Periodic Cash Dividend or
          a dividend paid in Common Shares, but including any dividend payable
          in securities other than Common Shares), (ii) 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, exchange 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 rights or warrants referred to in
          Subsection 2.3(f)) or (iii) other securities of the Corporation, the
          Exercise Price in effect after such record date shall be equal to 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 or other securities so to be distributed applicable
          to each of the securities purchasable upon exercise of one Right. Such
          adjustment shall be made successively whenever such a record date is
          fixed.

     (h)  Each adjustment made pursuant to Section 2.3 shall be made as of

          (i)  the payment or effective date for the applicable dividend,
               subdivision, change, combination or issuance, in the case of an
               adjustment made pursuant to Subsection 2.3(b) above; and

          (ii) the record date for the applicable dividend or distribution, in
               the case of an adjustment made pursuant to Subsections 2.3(f) or
               2.3(g) above, subject to readjustment to reverse the same if such
               distribution shall not be made.

     (i)  In the event the Corporation shall at any time after the Record Time
          and prior to the Expiration Time issue any shares (other than Common
          Shares), or rights or warrants to


                                      -20-

          subscribe for or purchase any such shares, or Convertible Securities
          in respect of any such shares, in a transaction referred to in any of
          subclauses 2.3(b)(i) to (iv) above, if the Board of Directors acting
          in good faith determines that the adjustments contemplated by
          Subsections 2.3(b), 2.3(f) and 2.3(g) above in connection with such
          transaction will not appropriately protect the interests of the
          holders of Rights, the Board of Directors may from time to time, but
          subject to obtaining the prior approval of the holders of the Rights
          obtained as set forth in Subsection 5.4, determine what other
          adjustments to the Exercise Price, number of Rights or securities
          purchasable upon exercise of Rights would be appropriate and,
          notwithstanding Subsections 2.3(b), 2.3(f) and 2.3(g) above, such
          adjustments, rather than the adjustments contemplated by Subsections
          2.3(b), 2.3(f) and 2.3(g) above, shall be made upon the Board of
          Directors providing written certification thereof to the Rights Agent
          pursuant to Subsection 2.3(q).

     (j)  Notwithstanding anything herein to the contrary, no adjustment of the
          Exercise Price shall be required unless such adjustment would require
          an increase or decrease of at least 1% in such Exercise Price;
          provided, however, that any adjustments which by reason of this
          Subsection 2.3(j)) are not required to be made shall be carried
          forward and taken into account in any subsequent adjustment. All
          adjustments to the Exercise Price made pursuant to this Section 2.3
          shall be calculated to the nearest cent.

     (k)  All Rights originally issued by the Corporation subsequent to any
          adjustment made to an 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
          the Rights, all subject to further adjustment as provided herein.

     (1)  Unless the Corporation shall have exercised its election, as provided
          in Subsection 2.3(m), upon each adjustment of an Exercise Price as a
          result of the calculations made in Subsections 2.3(f) and 2.3(g), each
          Right outstanding immediately prior to the making of such adjustment
          shall thereafter evidence the right to purchase, at the adjusted
          Exercise Price, that number of Common Shares obtained by:

          (i)  multiplying (A) the number of Common Shares covered by a Right
               immediately prior to such adjustment, by (B) the Exercise Price
               in effect immediately prior to such adjustment; and

          (ii) dividing the product so obtained by the Exercise Price in effect
               immediately after such adjustment.

     (m)  The Corporation may elect on or after the date of any adjustment of an
          Exercise Price to adjust the number of Rights, in lieu of any
          adjustment in the number of Common Shares purchasable upon the
          exercise of a Right. Each of the Rights outstanding after the
          adjustment in the number of Rights shall be exercisable for the number
          of Common Shares for which a Right was exercisable immediately prior
          to such adjustment. Each Right held of record prior to such adjustment
          of the number of Rights shall become the number of Rights obtained by
          dividing the relevant Exercise Price in effect immediately prior to
          adjustment of the relevant Exercise Price by the relevant Exercise
          Price in effect immediately after adjustment of the relevant Exercise
          Price. The Corporation shall make a public announcement of its
          election to adjust the number of Rights, indicating the record date
          for the adjustment, and, if known at the time, the amount of the
          adjustment to be made. This record date may be the date on which the
          relevant Exercise Price is adjusted or any day thereafter, but, if the
          Rights Certificates


                                      -21-

          have been issued, shall be at least 10 calendar days later than the
          date of the public announcement. If Rights Certificates have been
          issued, upon each adjustment of the number of Rights pursuant to this
          Subsection 2.3(m), the Corporation shall, as promptly as practicable,
          cause to be distributed to holders of record of Rights Certificates on
          such record date, Rights Certificates evidencing, subject to Section
          5.5, the additional Rights to which such holders shall be entitled as
          a result of such adjustment, or, at the option of the Corporation,
          shall cause to be distributed to such holders of record in
          substitution and replacement for the Rights Certificates held by such
          holders prior to the date of adjustment, and upon surrender thereof,
          if required by the Corporation, new Rights Certificates evidencing all
          the Rights to which such holders shall be entitled after such
          adjustment. Rights Certificates so to be distributed shall be issued,
          executed and countersigned in the manner provided for herein and may
          bear, at the option of the Corporation, the relevant adjusted Exercise
          Price and shall be registered in the names of holders of record of
          Rights Certificates on the record date specified in the public
          announcement.

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

     (o)  Notwithstanding anything in this Section 2.3 to the contrary, the
          Corporation shall be entitled to make such adjustments in the Exercise
          Price, in addition to those adjustments expressly required by this
          Section 2.3, as and to the extent that in its good faith judgment the
          Board of Directors shall determine to be advisable in order that any
          (i) subdivision or consolidation of the Common Shares, (ii) issuance
          wholly for cash of any Common Shares at less than the applicable
          Market Price, (iii) issuance wholly for cash of any Common Shares or
          securities that by their terms are exchangeable for or convertible
          into or give a right to acquire Common Shares, (iv) stock dividends,
          or (v) issuance of rights, options or warrants referred to in this
          Section 2.3, hereafter made by the Corporation to holders of its
          Common Shares, shall not be taxable to such shareholders.

     (p)  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 represent the securities so
          purchasable which were represented in the initial Rights Certificates
          issued hereunder.

     (q)  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


                                      -22-

               Rights who requests a copy.

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

2.4  DATE ON WHICH EXERCISE IS EFFECTIVE

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

     (b)  Promptly following 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 statement describing the Rights, and the Rights
          Agent shall countersign (manually or by facsimile signature) and
          deliver such Rights Certificates and statement to the holders of the
          Rights pursuant to Section 2.2 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)  After the Separation Time, the Corporation shall cause to be kept a
          register (the "Rights Register") in which, subject to such reasonable
          regulations as it may prescribe, the Corporation 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 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.

     (b)  After the Separation Time and prior to the Expiration Time, upon
          surrender for registration of transfer or exchange of any Rights
          Certificate, and subject to the provisions of Subsections


                                      -23-

          2.6(d) and 3.1(b) below, the Corporation will execute, and the Rights
          Agent will countersign, deliver and register, 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 valid obligations of the Corporation, and
          such Rights shall be entitled to the same benefits under this
          Agreement as the Rights surrendered upon such registration of transfer
          or exchange.

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

2.7  MUTILATED, LOST, STOLEN AND DESTROYED 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 fees
          and expenses of the Rights Agent) connected therewith.

     (d)  Every new Rights Certificate issued pursuant to this Section 2.7 in
          lieu of any destroyed, lost or stolen Rights Certificate shall
          evidence a contractual obligation of the 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


                                      -24-

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 Rights shall mean the registered holder of such Rights
(or, prior to the Separation Time, the associated Common Shares).

2.9  DELIVERY AND CANCELLATION OF CERTIFICATES

     All Rights Certificates surrendered upon exercise or for redemption, for
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.

2.10 AGREEMENT OF RIGHTS HOLDERS

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

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

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

     (c)  that, after the Separation Time, the Rights 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 its right to receive any
          fractional Rights or any fractional Common Shares or other securities
          upon exercise of a Right (except as provided herein);

     (f)  that, subject to the provisions of Section 5.4 without the approval of
          any holder of Rights or Voting Shares and upon the sole authority of
          the Board of Directors acting in good faith, this Agreement may be
          supplemented or amended from time to time as provided herein; and


                                      -25-

     (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.

                            ADJUSTMENTS TO THE RIGHTS

3.1  FLIP-IN EVENT

     (a)  Subject to subsections 3. 1(b) and 5.1(b), 5.1(c) and 5.1(d) hereof,
          in the event that prior to the Expiration Time a Flip-in Event occurs,
          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 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 accordance with the
          terms hereof, that number of Common Shares of the Corporation as have
          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 anything in this Agreement to the contrary, upon the
          occurrence of any Flip-in Event, any Rights that are or were
          Beneficially Owned on or after the earlier of the Separation Time and
          the Stock Acquisition Date, or which may thereafter be Beneficially
          Owned, by:

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

          (ii) a transferee of Rights, direct or indirect, from an Acquiring
               Person (or from any Affiliate or Associate of an Acquiring Person
               or any Person acting jointly or in concert with an Acquiring
               Person or any associate or Affiliate thereof) where such a
               transferee becomes a transferee concurrently with or subsequent
               to the Acquiring Person becoming an Acquiring Person in a
               transfer that the Board of Directors has determined is part of a
               plan, arrangement or scheme of an Acquiring Person (or of any
               Person acting jointly or in concert with an Acquiring Person or
               any Associate or Affiliate of an Acquiring Person), 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 any transferee of, or other successor
          entitled to, such Rights, whether directly or indirectly) shall
          thereafter have no right to exercise such Rights under any provisions
          of this Agreement and further shall thereafter not have any rights
          whatsoever with respect to such Rights, whether under any provision of
          this Agreement or otherwise. The holder of any Rights


                                      -26-

          represented by a Rights Certificate which is submitted to the Rights
          Agent upon exercise or for registration of transfer or exchange which
          does not contain the necessary certifications set forth in the Rights
          Certificate establishing that such Rights are not void under this
          Subsection 3.1(b) shall be deemed to be an Acquiring Person for the
          purposes of this Subsection 3.1 (b) and such Rights shall become null
          and void.

     (c)  Any Rights Certificate that represents Rights Beneficially Owned by a
          Person described in either of subclauses 3.1(b)(i) or 3.1(b)(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 or will be deemed to 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 Rights Agreement) or acting jointly or in concert with any of
               them. This Rights Certificate and the Rights represented hereby
               shall be void in the circumstances specified in Subsection 3.1(b)
               of the Shareholder Rights Plan Agreement."

          The Rights Agent shall not be under any responsibility to ascertain
          the existence of facts that would require the imposition of such
          legend but shall be required to impose such legend only if instructed
          to do so in writing by the Corporation or if a holder fails to certify
          upon transfer or exchange in the space provided to do so.

     (d)  After the Separation Time, the Corporation shall do all such acts and
          things necessary and within its power to ensure compliance with the
          provisions of this Section 3.1 including, without limitation, all such
          acts and things as may be required to satisfy the requirements of the
          Business Corporations Act, the Securities Act and applicable
          securities laws or comparable legislation in each of the provinces of
          Canada and in any other jurisdiction where the Corporation is subject
          to such laws and the rules of the stock exchanges or quotation systems
          where the Common Shares are listed or quoted at such time in respect
          of the issue of Common Shares upon the exercise of Rights in
          accordance with this Agreement.

3.2  FIDUCIARY DUTIES OF THE BOARD OF DIRECTORS OF THE CORPORATION

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

                                    ARTICLE 4
                                THE RIGHTS AGENT

4.1  GENERAL

     (a)  The Corporation hereby appoints the Rights Agent to act as agent for
          the Corporation and the


                                      -27-

          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 subject to
          the prior written approval of the Rights Agent. 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 with the written approval of the Rights
          Agent. The Corporation agrees to pay to the Rights Agent reasonable
          compensation for all services rendered by it hereunder and, from time
          to time, on demand of the Rights Agent, its reasonable expenses and
          other disbursements reasonably incurred in the administration and
          execution of this Agreement and the exercise and performance of its
          duties hereunder, including the reasonable fees and disbursements of
          counsel and other experts consulted by the Rights Agent pursuant to
          Subsection 4.3(a). The Corporation also agrees to indemnify the Rights
          Agent, its officers, directors, employees and agents for, and to hold
          it harmless against, any loss, liability, cost, claim, action, damage
          or expense, incurred without negligence, bad faith or willful
          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 legal costs and
          expenses, which right to indemnification will survive the termination
          of this Agreement or the removal or resignation 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.

     (c)  The Corporation shall inform the Rights Agent in a reasonably timely
          manner of events which may materially affect the administration of
          this Agreement by the Rights Agent and, at any time upon request,
          shall provide to the Rights Agent an incumbency certificate certifying
          the then current officers of the Corporation.

4.2  MERGER, AMALGAMATION, 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 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 filling of any document or any
          further act on the part of any of the parties hereto, provided that
          such corporation would be eligible for appointment as a successor
          Rights Agent under the provisions of Section 4.4 hereof. In case at
          the time such successor Rights Agent succeeds to the agency created by
          this Agreement any of the Rights Certificates have been countersigned
          but not delivered any such successor Rights Agent may adopt the
          countersignature of the predecessor Rights Agent and deliver such
          Rights Certificates so countersigned; and in case at that time any of
          the Rights Certificates have not been countersigned, any successor
          Rights Agent may countersign such Rights Certificates either in the
          name of the predecessor Rights Agent or in the name of the successor
          Rights Agent; and in all such cases such Rights Certificates will have
          the full force provided in the Rights Certificates and in this
          Agreement.


                                      -28-

     (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 retain and consult with legal counsel (who may be
          legal counsel for the Corporation) or such other experts that the
          Rights Agent considers necessary to carry out its duties under this
          Agreement and the opinion of such counsel or other expert 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), consult
          with such other experts as the Rights Agent shall consider necessary
          or appropriate to properly carry out the duties and obligations
          imposed under this Agreement and the Rights Agent shall be entitled to
          act and rely in good faith on the advice of any such expert.

     (b)  Whenever in the performance of its duties under this Agreement the
          Rights Agent deems it necessary or desirable that any fact or matter
          be proved or established by the Corporation prior to taking or
          suffering any action hereunder, such fact or matter (unless other
          evidence in respect thereof be herein specifically prescribed) may be
          deemed to be conclusively proved and established by a certificate
          signed by a person believed by the Rights Agent to be the President,
          Chief Executive Officer, Chief Financial Officer, a Vice President or
          the Secretary or 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.

     (c)  The Rights Agent will be liable hereunder only for its own negligence,
          bad faith or willful 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, and 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 Common
          Share certificate, or Rights Certificate (except its countersignature
          thereon) 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


                                      -29-

          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 or any
          written notice from the Corporation or any holder that a Person has
          become an Acquiring Person); 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 any Common Shares, when issued, being duly and validly
          authorized, issued and delivered as 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 individual believed by the Rights Agent to be the President,
          Chief Executive Officer, Chief Financial Officer, a Vice President or
          the Secretary or 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. It is understood that instructions to the Rights Agent
          shall, except where circumstances make it impractical 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
          practicable after the giving of such instructions.

     (h)  Subject to applicable law, the Rights Agent and any shareholder or
          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
          the 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, 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 by giving 60 days' prior written notice (or such lesser notice as is
acceptable to the Corporation) to the Corporation, to each transfer agent of
Common Shares and to the holders of the Rights, all in accordance with Section
5.9 and at the expense of the Corporation. The Corporation may remove the Rights
Agent by giving 30 days' prior written notice to the Rights Agent, to each
transfer agent of the Common Shares and to the holders of the Rights in
accordance with Section 5.9. If the Rights Agent should resign or be removed or
otherwise become incapable


                                      -30-

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 or by the holder of
any Rights (which holder shall, with such notice, submit such holder's Rights
Certificate for inspection of the Corporation), then the holder of any Rights or
the Rights Agent may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent at the Corporation's expense. Any successor
Rights Agent, whether appointed by the Corporation or by such a court, must be a
corporation incorporated under the laws of Canada or a province thereof and
authorized to carry on the business of a trust company in the Province of
Ontario. After appointment, the successor Rights Agent will be vested with the
same powers, rights, duties and responsibilities as if it had been originally
named as Rights Agent without further act or deed; but the predecessor Rights
Agent, upon receipt of any outstanding fees and expenses then owing, 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 the successor
Rights Agent, as the case may be

                                    ARTICLE 5
                                  MISCELLANEOUS

5.1  REDEMPTION, WAIVER 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 5.1(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 $0.000001
          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 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 Common Shares and


                                      -31-

          provided, further, that if the Board of Directors 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 Common 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
               Common 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 Common Shares pursuant to 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 Common 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 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 of Directors 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 the Separation Time shall be deemed not to have occurred
          and Rights shall remain attached to the outstanding Common Shares,


                                      -32-

          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 Common
          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
          Common Shares or the holders of Rights have approved a redemption of
          Rights in accordance with subsection 5.1(f) or 5.1(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 will have any rights pursuant to this Agreement or in respect of
any Right after the Expiration Time, except in respect of any right to receive
cash, securities or other property which has accrued at the Expiration Time and
except as specified in Subsections 4.1(a) and 4.1(b) hereof.

5.3  ISSUANCE OF NEW RIGHTS CERTIFICATES

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

5.4  SUPPLEMENTS AND AMENDMENTS

     (a)  Subject to Subsections 5.4(b) and (c) and this Subsection 5.4(a), the
          Corporation may from time to time amend, vary or delete any of the
          provisions of this Agreement and the Rights provided that no
          amendment, variation or deletion made on or after the date of the
          meeting of Shareholders at which the resolution referred to in Section
          5.18 is to be considered shall be made without the prior consent of
          the holders of the Rights, given as provided in this Section 5.4,
          except that amendments, variations or deletions made for any of the
          following purposes shall not require such prior approval but shall be
          subject to subsequent ratification in accordance with Subsection
          5.4(b):


                                      -33-

          (i)  in order to make such changes as are necessary in order to
               maintain the validity of this Agreement and the Rights as a
               result of any change in any applicable legislation, regulations
               or rules; or

          (ii) in order to make such changes as are necessary in order to cure
               any clerical or typographical error.

     (b)  Any amendment, variation or deletion made by the Board of Directors
          pursuant to Subsections 5.4(a)(i) or (ii) shall:

          (i)  if made prior to the Separation Time, be submitted to the
               shareholders of the Corporation at the next meeting of
               shareholders and the shareholders may, by resolution passed by a
               majority of the votes cast by Independent Shareholders who vote
               in respect of such amendment, variation or deletion, confirm or
               reject such amendment or supplement; or

          (ii) if made after the Separation Time, be submitted to the holders of
               Rights at a meeting to be held on a date not later than the date
               of the next meeting of shareholders of the Corporation and the
               holders of Rights may, by resolution passed by a majority of the
               votes cast by the holders of Rights which have not become void
               pursuant to Subsection 3.l(b) who vote in respect of such
               amendment, variation or deletion, confirm or reject such
               amendment or supplement.

          Any amendment, variation or deletion pursuant to Subsection 5.4 shall
          be effective only when so consented to by the holders of Voting Shares
          or Rights, as applicable (except in the case of an amendment,
          variation or deletion referred to in any of Clauses 5.4(a)(i) or (ii),
          which shall be effective from the date of the resolution of the Board
          of Directors adopting such amendment, variation or deletion and shall
          continue in effect until it ceases to be effective (as in this
          paragraph described) and, where such amendment, variation or deletion
          is confirmed, it shall continue in effect in the form so confirmed).
          If an amendment, variation or deletion pursuant to Clause 5.4(a)(i) or
          (ii) 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, variation or deletion 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, vary or delete any provision of this Agreement to
          substantially the same effect shall be effective until confirmed by
          the shareholders or holders of Rights, as the case may be.

     (c)  For greater certainty, (i) no amendment, variation or deletion to the
          provisions of Article 4 shall be made except with the concurrence of
          the Rights Agent thereto, and (ii) neither the exercise by the Board
          of Directors of any power or discretion conferred on it hereunder nor
          the making by the Board of Directors of any determination or the
          granting of any waiver it is permitted to make or give hereunder shall
          constitute an amendment, variation or deletion of the provisions of
          this Agreement or the Rights, for purposes of this Section 5.4 or
          otherwise.

     (d)  The approval, confirmation or consent of the holders of Rights with
          respect to any matter arising hereunder shall be deemed to have been
          given if the action requiring such approval, confirmation or consent
          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


                                      -34-

          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 or which, prior to the
          Separation Time, are held otherwise than by 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 Corporation's Bylaws and the Business
          Corporations Act with respect to meetings of shareholders of the
          Corporation.

     (e)  The Corporation shall be required to provide the Rights Agent with
          notice in writing of any such amendment, rescission or variation to
          this Agreement as referred to in this Section 5.4 within 5 days of
          effecting such amendment, variation or deletion.

5.5  FRACTIONAL RIGHTS AND FRACTIONAL SHARES

     (a)  The Corporation will 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, in lieu of such
          fractional Rights, 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. The Rights Agent shall have no obligation to
          make 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)
          hereof.

     (b)  The Corporation shall not be required to issue fractional Common
          Shares upon exercise of the Rights or to distribute certificates that
          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. The Rights
          Agent shall have no obligation to make payments in lieu of fractional
          Common Shares 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) hereof.

5.6  RIGHTS OF ACTION

     Subject to the terms of this Agreement, rights of action in respect of this
Agreement, other than rights of action vested solely in the Rights Agent, are
vested in the respective holders of the Rights; and any holder of any Rights,
without the consent of the Rights Agent or of the holder of any other Rights
may, on such holder's own behalf and for such holder's own benefit and the
benefit of other holders of Rights, enforce, and may institute and maintain any
suit, action or proceeding against the Corporation to enforce, or otherwise act
in respect of, such holder's right to exercise such holder's Rights 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 or Rights Certificate 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


                                      -35-

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 shall have been exercised in accordance with the provisions hereof.

5.8  NOTICE OF PROPOSED ACTIONS

     In case the Corporation proposes after the Separation Time and prior to the
Expiration Time 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
shall specify the date on which such liquidation, dissolution, or winding up is
to take place, and such notice shall be so given at least 10 Business Days prior

(including legal fees) incurred by such holder in actions to enforce his rights
pursuant to any Rights or this Agreement.

5.11 REGULATORY APPROVALS

     Any obligation of the Corporation or action or event contemplated by this
Agreement, shall be subject to applicable law and to the receipt of any
requisite approval or consent from any governmental or regulatory authority.

5.12 DECLARATION AS TO NON-CANADIAN AND 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 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.

the holders of the Rights.

Independent Shareholders for their consideration and, if thought advisable,

5.21 SEVERABILITY

     If any term or provision hereof or the application thereof to any
circumstance is, in any jurisdiction and to any extent, invalid or
unenforceable, such term or provision will be ineffective only to the extent of

THE RIGHTS ARE SUBJECT TO REDEMPTION, AT THE OPTION OF THE CORPORATION, ON THE
TERMS SET FORTH IN THE SHAREHOLDER RIGHTS PLAN AGREEMENT. UNDER CERTAIN
CIRCUMSTANCES (SPECIFIED IN SUBSECTION 3.1(b) OF SUCH AGREEMENT), RIGHTS
BENEFICIALLY OWNED BY AN ACQUIRING PERSON, CERTAIN RELATED PARTIES OF AN
ACQUIRING PERSON OR A TRANSFEREE OF AN ACQUIRING PERSON OR ANY SUCH RELATED

                               RIGHTS CERTIFICATE

     This certifies that ______________ 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 made as of April ___, 2005 (the "Rights Agreement") between GSI
Lumonics Inc., a corporation existing under the laws of New Brunswick (the
"Corporation") and Computershare Trust Company of Canada, a trust company
incorporated under the laws of Canada, as Rights Agent (the "Rights Agent"),
which term shall include any successor Rights Agent under the Rights Agreement,
to purchase from the Corporation, at any time after the Separation Time and
prior to the Expiration Time (as such terms are defined in the Rights
Agreement), one fully paid common share of the Corporation (a "Common Share") at
the Exercise Price referred to below, upon presentation and surrender of this
Rights Certificate, together with the Form of Election to Exercise appropriately
completed and duly executed, to the Rights Agent at its principal office in
Toronto. Until adjustment thereof in certain events as provided in the Rights
Agreement, the Exercise Price shall be $200.00 per Right (payable by certified
cheque, bankers draft or money order payable to the order of the Corporation).
The number of Common Shares which may be purchased for the Exercise Price is
subject to adjustment as set forth in the Rights Agreement.

     This Rights Certificate is subject to all of the terms, provisions and
conditions of the Rights Agreement, which terms, provisions and conditions are
hereby incorporated by reference and made a part hereof and to which Rights
Agreement reference is hereby made for a full description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Rights Agent, the Corporation and the holder of the Rights Certificates. Copies
of the Rights Agreement are on file at the registered office of the Corporation
and are available upon written request.

     This Rights Certificate, with or without other Rights Certificates, upon
surrender at the principal office of the Rights Agent in Toronto, Ontario may be
exchanged for another Rights Certificate or Rights Certificates of like tenor
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.

     Subject to the provisions of the Rights Agreement the Rights evidenced by
this Certificate may be redeemed by the Corporation at a redemption price of
$0.000001 per Right subject to adjustment in certain events.


                                      -41-

     No fractional Common Shares will be issued upon the exercise of any Right
or Rights evidenced hereby, but in lieu thereof a cash payment will be made, as
provided in the Rights Agreement.

     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
any other securities which may at any time be issuable upon the exercise hereof,
nor shall anything contained in the Rights Agreement or herein be construed to
confer upon the holder hereof, as such, any of the rights of a shareholder of
the Corporation or any right to vote for the election of directors or upon any
matter submitted to shareholders at any meeting thereof, or to give or withhold
consent to any corporate action, or to receive notice of any meeting or other
actions affecting shareholders (except as provided in the Rights Agreement), or
to receive dividends or subscription rights or otherwise, until the Rights
evidenced by this Rights Certificate shall have been exercised as provided in
the Rights Agreement.

     This Rights Certificate shall not be valid for any purpose until it shall
have been countersigned by the Rights Agent.

WITNESS the facsimile signature of the proper officers of the Corporation.
