Beneficiary Votes as to which such Beneficiary is entitled to direct the vote
(or any lesser number thereof as may be set forth in the instructions);
provided, however, that such written instructions are received by the Trustee
from the Beneficiary prior to the time and date fixed by the Trustee for receipt
of such instructions in the notice given by the Trustee to the Beneficiary
pursuant to section 4.3.

       The Trustee shall cause a representative who is empowered by it to sign
and deliver, on behalf of the Trustee, proxies for Voting Rights to attend each
Parent Meeting. Upon submission by a Beneficiary (or its designee) of
identification satisfactory to the Trustee's representative, and at the
Beneficiary's request, such representative shall sign and deliver to such
Beneficiary (or its designee) a proxy to exercise personally the Beneficiary
Votes as to which such Beneficiary is otherwise entitled hereunder to direct the
vote, if such Beneficiary either (i) has not previously given the Trustee
instructions pursuant to section 4.3 in respect of such meeting or (ii) submits
to such representative written revocation of any such previous instructions. At
such meeting, the Beneficiary exercising such Beneficiary Votes shall have the
same rights as the Trustee to speak


                                     - 10 -



at the meeting in favour of any matter, question, proposal or proposition, to
vote by way of ballot at the meeting in respect of any matter, question,
proposal or proposition, and to vote at such meeting by way of a show of hands
in respect of any matter, question or proposition.

4.9    DISTRIBUTION OF WRITTEN MATERIALS

       Any written materials distributed by the Trustee pursuant to this
Agreement shall be sent by mail (or otherwise communicated in the same manner as
Parent utilizes in communications to holders of Parent Common Shares, subject to
applicable regulatory requirements and the Trustee being advised in writing as
to that manner of communications, and provided such manner of communications is
reasonably available to the Trustee) to each Beneficiary at its address as shown
on the books of Exchangeco. Exchangeco shall provide or cause to be provided to
the Trustee for purposes of communication, on a timely basis and without charge
or other expense:

       (a)     a current List; and

       (b)     upon the request of the Trustee, mailing labels to enable the
               Trustee to carry out its duties under this Agreement.

4.10   TERMINATION OF VOTING RIGHTS

       All of the rights of a Beneficiary with respect to the Beneficiary Votes
exercisable in respect of the Exchangeable Shares held by such Beneficiary,
including the right to instruct the Trustee as to the voting of or to vote
personally such Beneficiary Votes, shall be deemed to be surrendered by the
Beneficiary to Parent, Callco, Nova Scotia Company or Exchangeco, as the case
may be, and such Beneficiary Votes and the Voting Rights represented thereby
shall cease immediately upon (i) the valid exercise by the Beneficiary of the
Exchange Right, or the occurrence of the automatic exchange of Exchangeable
Shares for Parent Common Shares as specified in Article 5 (unless, in either
case, Parent shall not have delivered or caused to be delivered the requisite
Parent Common Shares issuable in exchange therefor to the Trustee pending
delivery to the Beneficiaries), or (ii) the retraction or redemption of
Exchangeable Shares pursuant to Article 6 or 7 of the Share Provisions, or (iii)
the effective date of the liquidation, dissolution or winding-up of Exchangeco
pursuant to Article 5 of the Share Provisions, or (iv) the purchase of
Exchangeable Shares from the holder thereof by Callco or Parent, as the case may
be, pursuant to the exercise by Callco of the Retraction Call Right, the
Redemption Call Right or the Liquidation Call Right or the exercise by Parent of
the Parent Call Right.

4.11   DISCLOSURE OF INTEREST IN EXCHANGEABLE SHARES

       The Trustee or Exchangeco shall be entitled to require any Beneficiary or
any Person who the Trustee or Exchangeco know or have reasonable cause to
believe to hold any interest whatsoever in an Exchangeable Share to confirm that
fact or to give such details as to who has an interest in such Exchangeable
Share as would be required (if the Exchangeable Shares were a class of "equity
shares" of Exchangeco) under section 101 of the Securities Act (Ontario) or
under section 147.11 of the Securities Act (Quebec), as each may be amended from
time to time, or as would be required under the articles of Parent or any laws
or regulations, or pursuant to the rules or regulations of any regulatory
authority, of the United States if the Exchangeable Shares were Parent Common
Shares.

                                    ARTICLE 5
                  EXCHANGE RIGHT AND AUTOMATIC EXCHANGE RIGHTS

5.1    GRANT AND OWNERSHIP OF EXCHANGE RIGHTS

       Parent hereby grants to the Trustee as trustee for and on behalf of, and
for the use and benefit of, the Beneficiaries the right (the "EXCHANGE RIGHT"),
upon the occurrence and during the continuance of an Insolvency Event, to
require Parent to purchase from each or any Beneficiary all or any part of the
Exchangeable Shares held by the Beneficiary and the Automatic Exchange Rights,
all in accordance with the provisions of this Agreement. Parent hereby
acknowledges receipt from the Trustee as trustee for and on behalf of the
Beneficiaries of good and valuable consideration (and the adequacy thereof) for
the grant of the Exchange Right and the Automatic Exchange Rights by Parent to
the Trustee. During the term of the Trust and subject to the terms and
conditions of this Agreement, the Trustee shall possess and be vested with full
legal ownership of the Exchange Right and the Automatic Exchange Rights and
shall be entitled to exercise all of the rights and powers of an owner with
respect to the Exchange Right and the Automatic Exchange Rights, provided that
the Trustee shall:

       (a)     hold the Exchange Right and the Automatic Exchange Rights and the
               legal title thereto as trustee solely for the use and benefit of
               the Beneficiaries in accordance with the provisions of this
               Agreement; and

       (b)     except as specifically authorized by this Agreement, have no
               power or authority to exercise or otherwise deal in or with the
               Exchange Right or the Automatic Exchange Rights, and the Trustee
               shall not exercise any such rights for any purpose other than the
               purposes for which the Trust is created pursuant to this
               Agreement.

       The obligations of Parent to issue Parent Common Shares pursuant to the
Exchange Right or the Automatic Exchange Rights are subject to all applicable
laws and regulatory and stock exchange requirements.

5.2    LEGENDED SHARE CERTIFICATES

       Exchangeco will cause each certificate representing Exchangeable Shares
to bear an appropriate legend notifying the Beneficiaries of:

       (a)     their right to instruct the Trustee with respect to the exercise
               of the Exchange Right in respect of the Exchangeable Shares held
               by a Beneficiary; and

       (b)     the Automatic Exchange Rights.

5.3    GENERAL EXERCISE OF EXCHANGE RIGHT

       The Exchange Right shall be and remain vested in and exercisable by the
Trustee. Subject to section 7.15, the Trustee shall exercise the Exchange Right
only on the basis of instructions received pursuant to this Article 5 from
Beneficiaries entitled to instruct the Trustee as to the exercise thereof. To
the extent that no instructions are received from a Beneficiary with


                                     - 12 -



respect to the Exchange Right, the Trustee shall not exercise or permit the
exercise of the Exchange Right.

5.4    PURCHASE PRICE

       The purchase price payable by Parent for each Exchangeable Share to be
purchased by Parent under the Exchange Right shall be an amount per share equal
to the sum of (i) the Current Market Price of a Parent Common Share on the last
Business Day prior to the day of closing of the purchase and sale of such
Exchangeable Share under the Exchange Right, which shall be satisfied in full by
Parent delivering or causing to be delivered to the Trustee on behalf of such
holder one Parent Common Share, plus (ii) to the extent not paid by Exchangeco
on the designated payment date therefor, an additional amount equal to the full
amount of all declared and unpaid dividends on each such Exchangeable Share held
by such holder on any dividend record date which occurred prior to the closing
of the purchase and sale. In connection with each exercise of the Exchange
Right, Parent shall provide to the Trustee an Officer's Certificate setting
forth the calculation of the purchase price for each Exchangeable Share. The
total purchase price for each such Exchangeable Share so purchased may be
satisfied only by Parent delivering or causing to be delivered to the Trustee,
on behalf of the relevant Beneficiary, one Parent Common Share and on the
applicable payment date a cheque for the balance, if any, of the purchase price
without interest, less any amounts withheld pursuant to section 5.13. Upon
payment by Parent of such purchase price the relevant Beneficiary shall cease to
have any right to be paid by Exchangeco any amount in respect of declared and
unpaid dividends on each such Exchangeable Share and Exchangeco shall cease to
be obligated to pay any amount in respect of such dividends.

5.5    EXERCISE INSTRUCTIONS

       Subject to the terms and conditions herein set forth, a Beneficiary shall
be entitled, upon the occurrence and during the continuance of an Insolvency
Event, to instruct the Trustee to exercise the Exchange Right with respect to
all or any part of the Exchangeable Shares registered in the name of such
Beneficiary on the books of Exchangeco. To cause the exercise of the Exchange
Right by the Trustee, the Beneficiary shall deliver to the Trustee, in person or
by certified or registered mail, at its principal office in Toronto or Montreal
or at such other places in Canada as the Trustee may from time to time designate
by written notice to the Beneficiaries, the certificates representing the
Exchangeable Shares which such Beneficiary desires Parent to purchase, duly
endorsed in blank for transfer, and accompanied by such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the CBCA and the by-laws of Exchangeco and such additional documents and
instruments as the Trustee, Parent and Exchangeco may reasonably require
together with (a) a duly completed form of notice of exercise of the Exchange
Right, contained on the reverse of or attached to the Exchangeable Share
certificates, stating (i) that the Beneficiary thereby instructs the Trustee to
exercise the Exchange Right so as to require Parent to purchase from the
Beneficiary the number of Exchangeable Shares specified therein, (ii) that such
Beneficiary has good title to and owns all such Exchangeable Shares to be
acquired by Parent free and clear of all liens, claims and encumbrances, (iii)
the names in which the certificates representing Parent Common Shares
transferable in connection with the exercise of the Exchange Right are to be
registered and (iv) the names and addresses of the Persons to whom such new
certificates should be delivered and (b) payment (or evidence satisfactory to
the Trustee, Exchangeco and Parent of payment) of the taxes (if any) payable as
contemplated by section 5.8. If only a part of the Exchangeable Shares


                                     - 13 -



represented by any certificate or certificates delivered to the Trustee are to
be purchased by Parent under the Exchange Right, a new certificate for the
balance of such Exchangeable Shares shall be issued to the holder at the expense
of Exchangeco.

5.6    DELIVERY OF PARENT COMMON SHARES

       Promptly after the receipt of the certificates representing the
Exchangeable Shares which the Beneficiary desires Parent to purchase under the
Exchange Right, together with such documents and instruments of transfer and a
duly completed form of notice of exercise of the Exchange Right (and payment of
taxes, if any, payable as contemplated by section 5.8 or evidence thereof), duly
endorsed for transfer to Parent, the Trustee shall notify Parent and Exchangeco
of its receipt of the same, which notice to Parent and Exchangeco shall
constitute exercise of the Exchange Right by the Trustee on behalf of the holder
of such Exchangeable Shares, and Parent shall promptly thereafter deliver or
cause to be delivered to the Trustee, for delivery to the Beneficiary of such
Exchangeable Shares (or to such other Persons, if any, properly designated by
such Beneficiary) certificates representing the number of Parent Common Shares
issuable in connection with the exercise of the Exchange Right, and on the
applicable payment date cheques payable at par at any branch of the bankers of
Parent for the balance, if any, of the total purchase price therefor without
interest (but in each case less any amounts withheld pursuant to section 5.13);
provided, however, that no such delivery shall be made unless and until the
Beneficiary requesting the same shall have paid (or provided evidence
satisfactory to the Trustee, Exchangeco and Parent of the payment of) the taxes
(if any) payable as contemplated by section 5.8 of this Agreement. Immediately
upon the giving of notice by the Trustee to Parent and Exchangeco of the
exercise of the Exchange Right as provided in this section 5.6, the closing of
the transaction of purchase and sale contemplated by the Exchange Right shall be
deemed to have occurred and the holder of such Exchangeable Shares shall be
deemed to have transferred to Parent all of such holder's right, title and
interest in and to such Exchangeable Shares and the related interest in the
Trust Estate free and clear of any lien, claim or encumbrance and shall cease to
be a holder of such Exchangeable Shares and shall not be entitled to exercise
any of the rights of a holder in respect thereof, other than the right to
receive his proportionate part of the total purchase price therefor, unless the
requisite number of Parent Common Shares is not delivered by, or on behalf of,
Parent to the Trustee within five Business Days of the date of the giving of
such notice by the Trustee or the balance of the purchase price, if any, is not
paid by Parent on the applicable payment date therefor, in which case the rights
of the Beneficiary shall remain unaffected until such Parent Common Shares are
so delivered, and the balance of the purchase price, if any, has been paid, by
Parent. Upon delivery by Parent to the Trustee of such Parent Common Shares, and
the balance of the purchase price, if any, the Trustee shall deliver such Parent
Common Shares and the balance of the purchase price, if any, to such Beneficiary
(or to such other Persons, if any, properly designated by such Beneficiary).
Concurrently with such Beneficiary ceasing to be a holder of Exchangeable
Shares, the Beneficiary shall be considered and deemed for all purposes to be
the holder of the Parent Common Shares delivered to it pursuant to the Exchange
Right.

5.7    EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION

       In the event that a Beneficiary has exercised its right under Article 6
of the Share Provisions to require Exchangeco to redeem any or all of the
Exchangeable Shares held by the Beneficiary (the "RETRACTED SHARES") and is
notified by Exchangeco pursuant to section 6.6 of the Share Provisions that
Exchangeco will not be permitted as a result of solvency requirements


                                     - 14 -



of applicable law to redeem all such Retracted Shares, and provided that Callco
shall not have exercised the Retraction Call Right with respect to the Retracted
Shares and that the Beneficiary has not revoked the retraction request delivered
by the Beneficiary to Exchangeco pursuant to section 6.7 of the Share Provisions
and provided further that the Trustee has received written notice of same from
Exchangeco or Callco, the retraction request will constitute and will be deemed
to constitute notice from the Beneficiary to the Trustee instructing the Trustee
to exercise the Exchange Right with respect to those Retracted Shares that
Exchangeco is unable to redeem. In any such event, Exchangeco hereby agrees with
the Trustee and in favour of the Beneficiary to promptly notify the Trustee of
such prohibition against Exchangeco redeeming all of the Retracted Shares and to
promptly forward or cause to be forwarded to the Trustee all relevant materials
delivered by the Beneficiary to Exchangeco or to the transfer agent of the
Exchangeable Shares (including without limitation, a copy of the retraction
request delivered pursuant to section 6.1 of the Share Provisions) in connection
with such proposed redemption of the Retracted Shares and the Trustee will
thereupon exercise the Exchange Right with respect to the Retracted Shares that
Exchangeco is not permitted to redeem and in respect of which Callco has not
exercised its Retraction Call Right and will require Parent to purchase such
shares in accordance with the provisions of this Article 5.

5.8    TAXES

       Upon any sale of Exchangeable Shares to Parent pursuant to the Exchange
Right or the Automatic Exchange Rights, the share certificate or certificates
representing Parent Common Shares to be delivered in connection with the payment
of the total purchase price therefor shall be issued in the name of the
Beneficiary of the Exchangeable Shares so sold or in such names as such
Beneficiary may otherwise direct in writing, provided such direction is received
by Parent prior to the time such shares are issued, without charge to the holder
of the Exchangeable Shares so sold; provided, however, that such Beneficiary (a)
shall pay (and none of Parent, Exchangeco or the Trustee shall be required to
pay) any documentary, stamp, transfer or other taxes that may be payable in
respect of any transfer of such Exchangeable Shares to Parent or in respect of
the issuance or delivery of such Parent Common Shares to such Beneficiary or any
other Person including, without limitation, in the event that Parent Common
Shares are being issued or transferred in the name of a clearing service or
depositary or a nominee thereof, or (b) shall have evidenced to the satisfaction
of the Trustee, Parent and Exchangeco that such taxes, if any, have been paid.

5.9    NOTICE OF INSOLVENCY EVENT

       As soon as practicable following the occurrence of an Insolvency Event or
any event that with the giving of notice or the passage of time or both would be
an Insolvency Event, Exchangeco and Parent shall give written notice thereof to
the Trustee. As soon as practicable following the receipt of notice from
Exchangeco or Parent of the occurrence of an Insolvency Event, or upon the
Trustee becoming aware of an Insolvency Event, the Trustee will mail to each
Beneficiary, at the expense of Parent (such funds to be received in advance), a
notice of such Insolvency Event in the form provided by Parent, which notice
shall contain a brief statement of the rights of the Beneficiaries with respect
to the Exchange Right.


                                     - 15 -



5.10   QUALIFICATION OF PARENT COMMON SHARES

       Parent covenants that if any Parent Common Shares to be issued and
delivered pursuant to the Exchange Right or the Automatic Exchange Rights
require registration or qualification with or approval of or the filing of any
document, including any prospectus or similar document, or the taking of any
proceeding with or the obtaining of any order, ruling or consent from any
governmental or regulatory authority or stock exchange under any Canadian or
United States federal, provincial or state law or regulation or pursuant to the
rules and regulations of any regulatory authority or the fulfillment of any
other Canadian or United States federal, provincial or state legal requirement
before such shares may be issued and delivered by Parent to the initial holder
thereof or in order that such shares may be freely traded thereafter (other than
any restrictions of general application on transfer by reason of a holder being
a "control person" of Parent for purposes of Canadian provincial securities law
or an "affiliate" of Parent for purposes of United States federal or state
securities law), Parent will in good faith expeditiously take all such actions
and do all such things as are reasonably necessary or desirable to cause such
Parent Common Shares to be and remain duly registered, qualified or approved.
Parent will in good faith expeditiously take all such actions and do all such
things as are reasonably necessary or desirable to cause all Parent Common
Shares to be delivered pursuant to the Exchange Right or the Automatic Exchange
Rights to be listed, quoted or posted for trading on all stock exchanges and
quotation systems on which issued Parent Common Shares have been listed by
Parent and remain listed and are quoted or posted for trading at such time.

5.11   PARENT COMMON SHARES

       Parent hereby represents, warrants and covenants that the Parent Common
Shares issuable as described herein will be duly authorized and validly issued
as fully paid and non-assessable and shall be free and clear of any lien, claim
or encumbrance.

5.12   AUTOMATIC EXCHANGE ON LIQUIDATION OF PARENT

       Parent will give the Trustee written notice of each of the following
events at the time set forth below:

       (a)     in the event of any determination by the Board of Directors of
               Parent to institute voluntary liquidation, dissolution or
               winding-up proceedings with respect to Parent or to effect any
               other distribution of assets of Parent among its stockholders for
               the purpose of winding up its affairs, at least 60 days prior to
               the proposed effective date of such liquidation, dissolution,
               winding-up or other distribution; and

       (b)     as soon as practicable following the earlier of (A) receipt by
               Parent of notice of, and (B) Parent otherwise becoming aware of,
               any instituted claim, suit, petition or other proceedings with
               respect to the involuntary liquidation, dissolution or winding-up
               of Parent or to effect any other distribution of assets of Parent
               among its stockholders for the purpose of winding up its affairs,
               in each case where Parent has failed to contest in good faith any
               such proceeding commenced in respect of Parent within 30 days of
               becoming aware thereof.


                                     - 16 -



        As soon as practicable following receipt by the Trustee from Parent of
notice of any event (a "LIQUIDATION EVENT") contemplated by section 5.12(a) or
5.12(b), the Trustee will give notice thereof to the Beneficiaries. Such notice
shall be provided to the Trustee by Parent and shall include a brief description
of the automatic exchange of Exchangeable Shares for Parent Common Shares
provided for in section 5.12.

        In order that the Beneficiaries will be able to participate on a pro
rata basis with the holders of Parent Common Shares in the distribution of
assets of Parent in connection with a Liquidation Event, on the fifth Business
Day prior to the effective date (the "LIQUIDATION EVENT EFFECTIVE DATE") of a
Liquidation Event, all of the then outstanding Exchangeable Shares (other than
those owned by Parent and its Affiliates) shall be automatically exchanged for
Parent Common Shares. To effect such automatic exchange, Parent shall purchase
on the fifth Business Day prior to the Liquidation Event Effective Date each
Exchangeable Share then outstanding and held by Beneficiaries, and each
Beneficiary shall sell the Exchangeable Shares held by it at such time, free and
clear of any lien, claim or encumbrance, for a purchase price per share equal to
the sum of: (i) the Current Market Price of a Parent Common Share on the fifth
Business Day prior to the Liquidation Event Effective Date, which shall be
satisfied in full by Parent delivering to the Beneficiary one Parent Common
Share, and (ii) to the extent not paid by Exchangeco on the designated payment
date therefor, an additional amount equal to the full amount of all declared and
unpaid dividends on each such Exchangeable Share held by such holder on any
dividend record date which occurred prior to the date of the exchange. Parent
shall provide the Trustee with an Officer's Certificate in connection with each
automatic exchange setting forth the calculation of the purchase price for each
Exchangeable Share.

        On the fifth Business Day prior to the Liquidation Event Effective Date,
the closing of the transaction of purchase and sale contemplated by the
automatic exchange of Exchangeable Shares for Parent Common Shares shall be
deemed to have occurred, and each Beneficiary shall be deemed to have
transferred to Parent all of the Beneficiary's right, title and interest in and
to such Beneficiary's Exchangeable Shares free and clear of any lien, claim or
encumbrance and the related interest in the Trust Estate, Exchangeco shall have
no liability to pay an amount in respect of declared and unpaid dividends to any
Beneficiary and each such Beneficiary shall cease to be a holder of such
Exchangeable Shares and Parent shall deliver or cause to be delivered to the
Beneficiary the Parent Common Shares deliverable upon the automatic exchange of
Exchangeable Shares for Parent Common Shares and on the applicable payment date
shall deliver to the Trustee for delivery to the Beneficiary a cheque for the
balance, if any, of the total purchase price for such Exchangeable Shares,
without interest, in each case less any amounts withheld pursuant to section
5.13. Concurrently with such Beneficiary ceasing to be a holder of Exchangeable
Shares, the Beneficiary shall be considered and deemed for all purposes to be
the holder of the Parent Common Shares issued pursuant to the automatic exchange
of such Beneficiary's Exchangeable Shares for Parent Common Shares and the
certificates held by the Beneficiary previously representing the Exchangeable
Shares exchanged by the Beneficiary with Parent pursuant to such automatic
exchange shall thereafter be deemed to represent Parent Common Shares issued to
the Beneficiary by Parent pursuant to such automatic exchange. Upon the request
of a Beneficiary and the surrender by the Beneficiary of Exchangeable Share
certificates deemed to represent Parent Common Shares, duly endorsed in blank
and accompanied by such instruments of transfer as Parent may reasonably
require, Parent shall deliver or cause to be delivered to the Beneficiary
certificates representing the Parent Common Shares of which the Beneficiary is
the holder.


                                     - 17 -



5.13   WITHHOLDING RIGHTS

       Parent, Exchangeco and the Trustee shall be entitled to deduct and
withhold from any dividend or consideration otherwise payable under this
Agreement to any holder of Exchangeable Shares or Parent Common Shares such
amounts as Parent, Exchangeco or the Trustee is required to deduct and withhold
with respect to such payment under the Income Tax Act (Canada), the United
States Internal Revenue Code of 1986 or any provision of federal, provincial,
territorial, state, local or foreign tax law, in each case as amended or
succeeded, or entitled to withhold under section 116 of the Income Tax Act
(Canada) or any corresponding provisions of provincial law. The Trustee may act
on the advice of counsel with respect to such matters. To the extent that
amounts are so withheld, such withheld amounts shall be treated for all purposes
as having been paid to the holder of the shares in respect of which such
deduction and withholding was made, provided that such withheld amounts are
actually remitted to the appropriate taxing authority. To the extent that the
amount so required or entitled to be deducted or withheld from any payment to a
holder exceeds the cash portion of the consideration otherwise payable to the
holder, Parent, Exchangeco and the Trustee are hereby authorized to sell or
otherwise dispose of such portion of the consideration as is necessary to
provide sufficient funds to Parent, Exchangeco or the Trustee, as the case may
be, to enable it to comply with such deduction or withholding requirement or
entitlement and Parent, Exchangeco or the Trustee shall notify the holder
thereof and remit to such holder any unapplied balance of the net proceeds of
such sale. Parent and Exchangeco represent and warrant to the Trustee in its
capacity as trustee on behalf of the Beneficiaries that, based upon facts
currently known to them, they have no current intention, as at the date of this
Agreement, to deduct or withhold, from any dividend paid to holders of
Exchangeable Shares, any amounts under the United States Internal Revenue Code
of 1986.

5.14   NO FRACTIONAL SHARES

       A holder of an Exchangeable Share shall not be entitled to any fraction
of a Parent Common Share upon the exercise of the Exchange Right or Automatic
Exchange Rights hereunder and no certificates representing any such fractional
interest shall be issued and such holder otherwise entitled to a fractional
interest will receive for such fractional interest from Parent on the designated
payment date to the extent not paid by Callco or Exchangeco a cash payment equal
to such fractional interest multiplied by the Current Market Price.

5.15   PROHIBITION ON VOLUNTARY LIQUIDATION

       Parent covenants that it shall not, and agrees to cause Callco to not,
take any action relating to a voluntary liquidation, dissolution or winding-up
of Exchangeco or its successors or Callco or its successors, as the case may be,
prior to the Redemption Date (as defined in the Share Provisions) that results
in the recognition under the Income Tax Act (Canada) (or the provincial Quebec
equivalent) of any accrued gain on a holder's Exchangeable Shares, recognition
of which was deferred on the consummation of the transactions contemplated by
the Combination Agreement.

               Automatic Exchange Rights, in each case in accordance with the
               provisions of this Agreement, and in connection therewith
               receiving from Beneficiaries Exchangeable Shares and other
               requisite documents and distributing to such Beneficiaries Parent
               Common Shares and cheques, if any, to which such Beneficiaries
               are entitled upon the exercise of the Exchange Right or pursuant
               to the Automatic Exchange Rights, as the case may be;

       (f)     holding title to the Trust Estate;

       (g)     investing any moneys forming, from time to time, a part of the
               Trust Estate as provided in this Agreement;

       (h)     taking action on its own initiative or at the direction of a
               Beneficiary or Beneficiaries to enforce the obligations of Parent
               and Exchangeco under this Agreement; and

       (i)     taking such other actions and doing such other things as are
               specifically provided in this Agreement.


                                     - 19 -



       In the exercise of such rights, powers, duties and authorities the
Trustee shall have (and is granted) such incidental and additional rights,
powers, duties and authority not in conflict with any of the provisions of this
Agreement as the Trustee, acting in good faith and in the reasonable exercise of
its discretion, may deem necessary, appropriate or desirable to effect the
purpose of the Trust. Any exercise of such discretionary rights, powers, duties
and authorities by the Trustee shall be final, conclusive and binding upon all
Persons.

       The Trustee in exercising its rights, powers, duties and authorities
hereunder shall act honestly and in good faith and with a view to the best
interests of the Beneficiaries and shall exercise the care, diligence and skill
that a reasonably prudent trustee would exercise in comparable circumstances.

       The Trustee shall not be bound to give notice or do or take any act,
action or proceeding by virtue of the powers conferred on it hereby unless and
until it shall be specifically required to do so under the terms hereof; nor
shall the Trustee be required to take any notice of, or to do, or to take any
act, action or proceeding as a result of any default or breach of any provision
hereunder, unless and until notified in writing of such default or breach, which
notices shall distinctly specify the default or breach desired to be brought to
the attention of the Trustee, and in the absence of such notice the Trustee may
for all purposes of this Agreement conclusively assume that no default or breach
has been made in the observance or performance of any of the representations,
warranties, covenants, agreements or conditions contained herein.

7.2    NO CONFLICT OF INTEREST

       The Trustee represents to Parent and Exchangeco that at the date of
execution and delivery of this Agreement there exists no material conflict of
interest in the role of the Trustee as a fiduciary hereunder and the role of the
Trustee in any other capacity. The Trustee shall, within 90 days after it
becomes aware that such material conflict of interest exists, either eliminate
such material conflict of interest or resign in the manner and with the effect
specified in Article 10. If, notwithstanding the foregoing provisions of this
section 7.2, the Trustee has such a material conflict of interest, the validity
and enforceability of this Agreement shall not be affected in any manner
whatsoever by reason only of the existence of such material conflict of
interest. If the Trustee contravenes the foregoing provisions of this section
7.2, any interested party may apply to the Court for an order that the Trustee
be replaced as Trustee hereunder.

7.3    DEALINGS WITH TRANSFER AGENTS, REGISTRARS, ETC.

       Parent and Exchangeco irrevocably authorize the Trustee, from time to
time, to:

       (a)     consult, communicate and otherwise deal with the respective
               registrars and transfer agents, and with any such subsequent
               registrar or transfer agent, of the Exchangeable Shares and
               Parent Common Shares; and

       (b)     requisition, from time to time, (i) from any such registrar or
               transfer agent any information readily available from the records
               maintained by it which the Trustee may reasonably require for the
               discharge of its duties and responsibilities under this Agreement
               and (ii) from the transfer agent of Parent Common Shares, and any
               subsequent transfer agent of such shares, the share certificates
               issuable upon


                                     - 20 -



               the exercise from time to time of the Exchange Right and pursuant
               to the Automatic Exchange Rights in the manner specified in
               Article 5.

       Parent and Exchangeco irrevocably authorize their respective registrars
and transfer agents to comply with all such requests. Parent covenants that it
will supply its transfer agent with duly executed share certificates for the
purpose of completing the exercise from time to time of the Exchange Right and
the Automatic Exchange Rights, in each case pursuant to Article 5.

instructions to and from Beneficiaries and all transactions pursuant to the
Exchange Right and the Automatic Exchange Rights. On or before September 15,
2002, and on or before September 15th in every year thereafter, so long as the

               date;

       (b)     the number of exercises of the Exchange Right, if any, and the
               aggregate number of Exchangeable Shares received by the Trustee
               on behalf of Beneficiaries in consideration of the delivery by or
               on behalf of Parent of Parent Common Shares in connection with
               the Exchange Right, during the fiscal year of Parent ended on
               such August 31st; and

       (c)     any action taken by the Trustee in the performance of its duties
               under this Agreement which it had not previously reported and
               which, in the Trustee's opinion, materially affects the Trust
               Estate.

7.5    INCOME TAX RETURNS AND REPORTS

       The Trustee shall, to the extent necessary, prepare and file on behalf of
the Trust appropriate United States and Canadian income tax returns and any
other returns or reports as may be required by applicable law or pursuant to the

which the Exchangeable Shares are traded. In connection therewith, the Trustee
may obtain the advice and assistance of such experts or advisors as the Trustee
considers necessary or advisable (who may be experts or advisors to Parent or
Exchangeco). If requested by the Trustee, Parent or Exchangeco shall retain
qualified experts or advisors for the purpose of providing such tax advice or
assistance.

7.6    INDEMNIFICATION PRIOR TO CERTAIN ACTIONS BY TRUSTEE

       The Trustee shall exercise any or all of the rights, duties, powers or
authorities vested in it by this Agreement at the request, order or direction of
any Beneficiary upon such Beneficiary furnishing to the Trustee reasonable
funding, security or indemnity against the costs, expenses and liabilities which
may be incurred by the Trustee therein or thereby, provided that no


                                     - 21 -



Beneficiary shall be obligated to furnish to the Trustee any such security or
indemnity in connection with the exercise by the Trustee of any of its rights,
duties, powers and authorities with respect to the Special Voting Share pursuant
to Article 4, subject to section 7.15, and with respect to the Exchange Right
pursuant to Article 5, subject to section 7.15, and with respect to the
Automatic Exchange Rights pursuant to Article 5, subject to section 7.15.

       None of the provisions contained in this Agreement shall require the
Trustee to expend or risk its own funds or otherwise incur financial liability
in the exercise of any of its rights, powers, duties, or authorities unless
funded, given security and indemnified as aforesaid.

7.7    ACTION OF BENEFICIARIES

       No Beneficiary shall have the right to institute any action, suit or
proceeding or to exercise any other remedy authorized by this Agreement for the
purpose of enforcing any of its rights or for the execution of any trust or
power hereunder unless the Beneficiary has requested the Trustee to take or
institute such action, suit or proceeding and furnished the Trustee with the
funding, security or indemnity referred to in section 7.6 and the Trustee shall
have failed to act within a reasonable time thereafter. In such case, but not
otherwise, the Beneficiary shall be entitled to take proceedings in any court of
competent jurisdiction such as the Trustee might have taken; it being understood
and intended that no one or more Beneficiaries shall have any right in any
manner whatsoever to affect, disturb or prejudice the rights hereby created by
any such action, or to enforce any right hereunder or the Voting Rights, the
Exchange Right or the Automatic Exchange Rights, except subject to the
conditions and in the manner herein provided, and that all powers and trusts
hereunder shall be exercised and all proceedings at law shall be instituted, had
and maintained by the Trustee, except only as herein provided, and in any event
for the equal benefit of all Beneficiaries.

       The Trustee shall not be considered to be in contravention of any of its
rights, powers, duties and authorities hereunder if, when required, it acts and
relies in good faith upon statutory declarations, certificates, opinions or
reports furnished pursuant to the provisions hereof or required by the Trustee
to be furnished to it in the exercise of its rights, powers, duties and
authorities hereunder if such statutory declarations, certificates, opinions or
reports comply with the provisions of section 7.9, if applicable, and with any
other applicable provisions of this Agreement.

other action to be taken by the Trustee at the request or on the application of
Parent or Exchangeco, and except as otherwise specifically provided herein, such

hands of the Trustee may be invested and reinvested in the name or under the
control of the Trustee in securities in which, under the laws of the Province of
Ontario, trustees are authorized to invest trust moneys, provided that such
securities are stated to mature within two years after their purchase by the
Trustee, and the Trustee shall so invest such moneys on the written direction of
Exchangeco. Pending the investment of any moneys as hereinbefore provided, such
moneys may be deposited in the name of the Trustee in any chartered bank in
Canada or, with the consent of Exchangeco, in the deposit department of the
Trustee or any other specified loan or trust company authorized to accept

       The Trustee represents to Parent and Exchangeco that at the date of
execution and delivery by it of this Agreement it is authorized to carry on the
business of a trust company in each of the provinces of Canada but if,
notwithstanding the provisions of this section 7.14, it ceases to be so
authorized to carry on business, the validity and enforceability of this
Agreement and the Voting Rights, the Exchange Right and the Automatic Exchange
Rights shall not be affected in any manner whatsoever by reason only of such

Article 10.


                                     - 24 -



7.15   CONFLICTING CLAIMS

       If conflicting claims or demands are made or asserted with respect to any
interest of any Beneficiary in any Exchangeable Shares, including any
disagreement between the heirs, representatives, successors or assigns
succeeding to all or any part of the interest of any Beneficiary in any
Exchangeable Shares, resulting in conflicting claims or demands being made in
connection with such interest, then the Trustee shall be entitled, in its sole
discretion, to refuse to recognize or to comply with any such claims or demands.
In so refusing, the Trustee may elect not to exercise any Voting Rights,
Exchange Right or Automatic Exchange Rights subject to such conflicting claims
or demands and, in so doing, the Trustee shall not be or become liable to any
Person on account of such election or its failure or refusal to comply with any
such conflicting claims or demands. The Trustee shall be entitled to continue to
refrain from acting and to refuse to act until:

       (a)     the rights of all adverse claimants with respect to the Voting
               Rights, Exchange Right or Automatic Exchange Rights subject to
               such conflicting claims or demands have been adjudicated by a
               final judgment of a court of competent jurisdiction and all
               rights of appeal have expired; or

       (b)     all differences with respect to the Voting Rights, Exchange Right
               or Automatic Exchange Rights subject to such conflicting claims
               or demands have been conclusively settled by a valid written
               agreement binding on all such adverse claimants, and the Trustee
               shall have been furnished with an executed copy of such agreement
               certified to be in full force and effect.

       If the Trustee elects to recognize any claim or comply with any demand
made by any such adverse claimant, it may in its discretion require such
claimant to furnish such surety bond or other security satisfactory to the
Trustee as it shall deem appropriate to fully indemnify it as between all
conflicting claims or demands.

7.16   ACCEPTANCE OF TRUST

       The Trustee hereby accepts the Trust created and provided for by and in
this Agreement and agrees to perform the same upon the terms and conditions

                                    ARTICLE 8
                                  COMPENSATION

8.1    FEES AND EXPENSES OF THE TRUSTEE

       Parent and Exchangeco jointly and severally agree to pay the Trustee

Agreement and will reimburse the Trustee for all reasonable expenses (including,

the Trustee, fees paid to legal counsel and other experts and advisors and
travel expenses) and disbursements, including the cost and expense of any suit
or litigation of any character and any proceedings before any governmental
agency, reasonably incurred by the Trustee in connection with its duties under
this Agreement; provided that Parent and


                                     - 25 -



Exchangeco shall have no obligation to reimburse the Trustee for any expenses or
disbursements paid, incurred or suffered by the Trustee in any suit or
litigation in which the Trustee is determined to have acted in bad faith or with
fraud, gross negligence, recklessness or wilful misconduct.

                                    ARTICLE 9
                   INDEMNIFICATION AND LIMITATION OF LIABILITY

9.1    INDEMNIFICATION OF THE TRUSTEE

       Parent and Exchangeco jointly and severally agree to indemnify and hold
harmless the Trustee and each of its directors, officers and agents appointed
and acting in accordance with this Agreement (collectively, the "INDEMNIFIED
PARTIES") against all claims, losses, damages, reasonable costs, penalties,
fines and reasonable expenses (including reasonable expenses of the Trustee's
legal counsel) which, without fraud, gross negligence, wilful misconduct or bad
faith on the part of such Indemnified Party, may be paid, incurred or suffered
by the Indemnified Party by reason or as a result of the Trustee's acceptance or
administration of the Trust, its compliance with its duties set forth in this
Agreement, or any written or oral instruction delivered to the Trustee by Parent
or Exchangeco pursuant hereto.

       In no case shall Parent or Exchangeco be liable under this indemnity for
any claim against any of the Indemnified Parties unless Parent and Exchangeco
shall be notified by the Trustee of the written assertion of a claim or of any
action commenced against the Indemnified Parties, promptly after any of the
Indemnified Parties shall have received any such written assertion of a claim or
shall have been served with a summons or other first legal process giving
information as to the nature and basis of the claim. Subject to (ii) below,
Parent and Exchangeco shall be entitled to participate at their own expense in
the defence and, if Parent and Exchangeco so elect at any time after receipt of
such notice, either of them may assume the defence of any suit brought to
enforce any such claim. The Trustee shall have the right to employ separate
counsel in any such suit and participate in the defence thereof, but the fees
and expenses of such counsel shall be at the expense of the Trustee unless: (i)
the employment of such counsel has been authorized by Parent or Exchangeco; or
(ii) the named parties to any such suit include both the Trustee and Parent or
Exchangeco and the Trustee shall have been advised by counsel acceptable to
Parent or Exchangeco that there may be one or more legal defences available to
the Trustee that are different from or in addition to those available to Parent
or Exchangeco and that, in the judgment of such counsel, would present a
conflict of interest were a joint representation to be undertaken (in which case
Parent and Exchangeco shall not have the right to assume the defence of such
suit on behalf of the Trustee but shall be liable to pay the reasonable fees and
expenses of counsel for the Trustee). This indemnity shall survive the
termination of this Agreement and the resignation or removal of the Trustee.

9.2    LIMITATION OF LIABILITY

       The Trustee shall not be held liable for any loss which may occur by
reason of depreciation of the value of any part of the Trust Estate or any loss
incurred on any investment of funds pursuant to this Agreement, except to the
extent that such loss is attributable to the fraud, gross negligence,
recklessness, wilful misconduct or bad faith on the part of the Trustee.


                                     - 26 -



                                   ARTICLE 10
                                CHANGE OF TRUSTEE

10.1     RESIGNATION

       The Trustee, or any trustee hereafter appointed, may at any time resign
by giving written notice of such resignation to Parent and Exchangeco specifying
the date on which it desires to resign, provided that such notice shall not be
given less than thirty (30) days before such desired resignation date unless
Parent and Exchangeco otherwise agree and provided further that such resignation
shall not take effect until the date of the appointment of a successor trustee
and the acceptance of such appointment by the successor trustee. Upon receiving
such notice of resignation, Parent and Exchangeco shall promptly appoint a
successor trustee, which shall be a corporation organized and existing under the
laws of Canada or a province thereof and authorized to carry on the business of
a trust company in all provinces of Canada, by written instrument in duplicate,
one copy of which shall be delivered to the resigning trustee and one copy to
the successor trustee. Failing the appointment and acceptance of a successor
trustee, a successor trustee may be appointed by order of the Court upon
application of one or more of the parties to this Agreement. If the retiring
trustee is the party initiating an application for the appointment of a
successor trustee by order of the Court, Parent and Exchangeco shall be jointly
and severally liable to reimburse the retiring trustee for its legal costs and
expenses in connection with same.

10.2   REMOVAL

       The Trustee, or any trustee hereafter appointed, may (provided a
successor trustee is appointed) be removed at any time on not less than 30 days'
prior notice by written instrument executed by Parent and Exchangeco, in
duplicate, one copy of which shall be delivered to the trustee so removed and
one copy to the successor trustee.

10.3   SUCCESSOR TRUSTEE

       Any successor trustee appointed as provided under this Agreement shall
execute, acknowledge and deliver to Parent and Exchangeco and to its predecessor
trustee an instrument accepting such appointment. Thereupon the resignation or
removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations of its predecessor under this
Agreement, with the like effect as if originally named as trustee in this
Agreement. However, on the written request of Parent and Exchangeco or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of this Agreement, execute and deliver an
instrument transferring to such successor trustee all the rights and powers of
the trustee so ceasing to act. Upon the request of any such successor trustee,
Parent, Exchangeco and such predecessor trustee shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers.

10.4   NOTICE OF SUCCESSOR TRUSTEE

       Upon acceptance of appointment by a successor trustee as provided herein,
Parent and Exchangeco shall cause to be mailed notice of the succession of such
trustee hereunder to each


                                     - 27 -



Beneficiary specified in a List. If Parent or Exchangeco shall fail to cause
such notice to be mailed within 10 days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be mailed at
the expense of Parent and Exchangeco.

11.1   CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.

       As long as any outstanding Exchangeable Shares are owned by any Person
other than Parent or any of its Affiliates, Parent shall not consummate any
transaction (whether by way of reconstruction, reorganization, consolidation,
arrangement, merger, transfer, sale, lease or otherwise) whereby all or
substantially all of its undertaking, property and assets would become the
property of any other Person or, in the case of a merger, of the continuing
corporation or other entity resulting therefrom unless, but may do so if:

       (a)     such other Person or continuing corporation or, in the event of
               any merger, amalgamation or similar transaction pursuant to which

               by the terms and provisions of this Agreement, in either case
               together with such other instruments (if any) as are reasonably
               necessary or advisable to evidence the assumption by the Parent
               Successor of liability for all moneys payable and property
               deliverable hereunder and the covenant of such Parent Successor

               acting reasonably, and in the opinion of legal counsel to the
               Trustee, be upon such terms and conditions as substantially to
               preserve and not to impair in any material respect any of the
               rights, duties, powers and authorities of the Trustee or of the
               Beneficiaries hereunder.

       Subject to Sections 12.2, 12.4 and 14.1, this Agreement may not be

of:

       (a)     adding to the covenants of any or all parties hereto for the
               protection of the Beneficiaries hereunder provided that the Board
               of Directors of each of Parent and Exchangeco shall be of the

               this Agreement as may be necessary or desirable with respect to
               matters or questions which, in the good faith opinion of the
               Board of Directors of each of Parent and Exchangeco and in the
               opinion of the Trustee, having in mind the best interests of the
               Beneficiaries, it may be expedient to make, provided that such
               Boards of Directors and the Trustee, acting on the advice of
               counsel, shall be of the opinion that such amendments and
               modifications will not be prejudicial to the interests of the
               Beneficiaries; or

       (c)     making such changes or corrections which, on the advice of
               counsel to Parent, Exchangeco and the Trustee, are required for
               the purpose of curing or correcting any ambiguity or defect or
               inconsistent provision or clerical omission or mistake or
               manifest error, provided that the Trustee, acting on the advice
               of counsel, and the Board of Directors of each of Parent and
               Exchangeco shall be of the opinion that such changes or
               corrections will not be prejudicial to the rights and interests
               of the Beneficiaries.

shall be called and held in accordance with the by-laws of Exchangeco, the Share
Provisions and all applicable laws.

12.4   CHANGES IN CAPITAL OF PARENT AND EXCHANGECO

       At all times after the occurrence of any event contemplated pursuant to
section 2.7 or 2.8 of the Support Agreement or otherwise, as a result of which

               the Trustee, will not be prejudicial to the interests of the
               Beneficiaries or are, in the opinion of counsel to the Trustee,
               necessary or advisable in order to incorporate, reflect or comply
               with any legislation the provisions of which apply to Parent,
               Exchangeco, the Trustee or this Agreement; and

       (c)     for any other purposes not inconsistent with the provisions of

               hereby, provided that, in the opinion of the Trustee, the rights
               of the Trustee and Beneficiaries will not be prejudiced thereby.
