                         DEFINITIONS AND INTERPRETATION

                         COVENANTS OF HOLDING AND ONEXCO

2.1               COVENANTS OF HOLDING REGARDING EXCHANGEABLE SHARES. So long as
any Exchangeable Shares are outstanding, Holding shall:

         (a)      take all such actions and do all such things as are
                  commercially reasonable to enable and permit Buyco, in
                  accordance with applicable law, to pay and otherwise perform
                  its obligations with respect to the payment of dividends,
                  Section 8.3 of the Exchangeable Share Provisions and the
                  satisfaction of the Liquidation Amount, the Retraction Price
                  or the Redemption Price in respect of each issued and
                  outstanding Exchangeable Share upon the liquidation,
                  dissolution or winding-up of Buyco, the delivery of a
                  Retraction Request by a holder of Exchangeable Shares or a
                  redemption of Exchangeable Shares by Buyco, as the case may
                  be, including, without limitation, all such actions and all
                  such things as are necessary or desirable to enable and permit
                  Buyco to cause to be delivered Holding Shares together with an
                  amount equal to any declared and unpaid dividends on such
                  Exchangeable Shares (a "Dividend Amount")

<PAGE>   3

                                       -3-

                  to the holders of Exchangeable Shares in accordance with
                  Articles 3, 4 or 5, as the case may be, of the Exchangeable
                  Share Provisions.

         (b)      take all such actions and do all such things as are reasonably
                  necessary or desirable to enable and permit Onexco to comply
                  with its covenants set out in Section 2.2 of this Agreement.

2.2               COVENANTS OF ONEXCO REGARDING EXCHANGEABLE SHARES. So long as
any Exchangeable Shares are outstanding, Onexco shall take all such actions and
do all such things as are commercially reasonable to enable and permit Buyco, in
accordance with applicable law, to pay and otherwise perform its obligations
with respect to the payment of dividends, Section 8.3 of the Exchangeable Share
Provisions and the satisfaction of the Liquidation Amount, the Retraction Price
or the Redemption Price in respect of each issued and outstanding Exchangeable
Share upon the liquidation, dissolution or winding-up of Buyco, the delivery of
a Retraction Request by a holder of Exchangeable Shares or a redemption of
Exchangeable Shares by Buyco, as the case may be, including, without limitation,
all such actions and all such things as are commercially reasonable to enable
and permit Buyco to cause to be delivered Holding Shares together with any
Dividend Amount, to the holders of Exchangeable Shares in accordance with the
provisions of Articles 3, 4 or 5, as the case may be, of the Exchangeable Share
Provisions. Notwithstanding the prior provisions, nothing contained in this
Support Agreement shall be deemed to require the board of directors of Holding,
or any member thereof, to take or omit to take any action that would be in
breach of applicable law. Furthermore, no action shall be required that could,
as determined in good faith by the board of directors of Holding, result in a
breach of the terms of any agreement in respect of indebtedness for borrowed
money of Holding on a consolidated basis, provided that Holding takes reasonable
steps to seek a waiver of any affected provision thereof. The existence of such
indebtedness shall be determined in accordance with United States generally
accepted accounting principles.

2.3               NOTIFICATION OF CERTAIN EVENTS. In order to assist Holding to
comply with its obligations hereunder and permit it to exercise the Liquidation
Call Right, the Retraction Call Right and the Redemption Call Right, Buyco shall
give prior written notice to Holding and Onexco 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
                  Buyco to institute voluntary liquidation, dissolution or
                  winding up proceedings or to effect any other distribution of
                  the assets of such corporation among its shareholders for the
                  purpose of winding up its affairs, at least 30 days prior to
                  the proposed effective date of such liquidation, dissolution,
                  winding up or other distribution;

         (b)      immediately, upon the earlier of receipt by Buyco of notice
                  of, or Buyco otherwise becoming aware of, any threatened or
                  instituted claim, suit, petition or other proceedings with
                  respect to the involuntary liquidation, dissolution or winding
                  up of

<PAGE>   4

                                       -4-

                  such company or to effect any other distribution of the assets
                  of such company among its shareholders for the purpose of
                  winding up its affairs;

         (c)      immediately, upon receipt by Buyco of a Retraction Request;
                  and

         (d)      on the same date on which notice of redemption is given to
                  holders of Exchangeable Shares, upon a determination of a
                  Redemption Date in accordance with the Exchangeable Share
                  Provisions.

2.4               DELIVERY OF HOLDING SHARES. In furtherance of its obligations
under Sections 2.1(a) and (b) hereof, upon notice of any event that requires
Buyco to cause to be delivered Holding Shares to any holder of Exchangeable
Shares, the board of directors of Holding, subject to fulfilment of its
fiduciary obligations, shall forthwith issue and deliver the requisite Holding
Shares to or to the order of the former holder of the surrendered Exchangeable
Shares, as Buyco or Onexco, as applicable, shall direct, and Holding shall
forthwith deliver to Onexco, and Onexco shall then immediately deliver to Buyco,
all cash or other property required to enable Buyco to pay the value of all
declared but unpaid dividends then accruing to the holders of the Dividend
Amount on such Exchangeable Shares. In consideration of the issuance of each
such Holding Share by Holding, together with the payment of such Dividend Amount
by Holding as applicable, Buyco or Onexco, as applicable, shall, as Holding
shall direct, issue to Holding such number of common shares of Buyco or Onexco,
as applicable, as is equal to the fair value of such Holding Shares plus the
Dividend Amount.

2.5               DUE PERFORMANCE. Holding shall duly and timely perform all of
its obligations provided for in the Share Exchange Agreement and any obligations
of Holding that may arise upon the exercise of Holding's rights under the
Exchangeable Share Provisions.

2.6               CAPITAL REORGANIZATION OF HOLDING. If at any time Holding's
share capital is reorganized or a consolidation, merger, recapitalization or
share exchange (statutory or otherwise) of Holding with or into another entity
(any such event being called a "Capital Reorganization"), Holding shall take
commercially reasonable actions to ensure that holders of Exchangeable Shares
whose Exchangeable Shares have not been exchanged or automatically exchanged for
Holding Shares in accordance with the Exchangeable Share Provisions or the Share
Exchange Agreement on or before the record date for such Capital Reorganization
shall receive, upon any such exchange occurring pursuant to the Exchangeable
Share Provisions or the Share Exchange Agreement at any time after the record
date for such Capital Reorganization, in lieu of the Holding Shares that such
holders would otherwise have been entitled to receive pursuant to the
Exchangeable Share Provisions or the Share Exchange Agreement, the number of
shares or other securities of Holding or of the body corporate resulting,
surviving or continuing from the Capital Reorganization, or other property, that
such holders would have been entitled to receive as a result of such Capital
Reorganization if, on the record date, such holders would have been the
registered holders of the number of Holding Shares to which such holders were
then entitled upon any exchange of their Exchangeable Shares into Holding Shares
in accordance with the Exchangeable Share Provisions or the Share Exchange

Agreement, subject to adjustment thereafter in the same manner, as nearly as may
be possible, as is provided for in Article 8 of the Exchangeable Share
Provisions.

                                    GENERAL

3.1               TERM. This Agreement shall come into force and be effective as
of the date hereof and shall terminate and be of no further force and effect at
such time as there are no Exchangeable Shares (or securities or rights
convertible into or exchangeable for or carrying rights to acquire Exchangeable
Shares) held by any party other than Holding and its Affiliates.

3.2               CHANGES IN CAPITAL OF HOLDING AND BUYCO. Notwithstanding the
provisions of Section 3.4 hereof, at all times after the occurrence of any event
effected pursuant to Section 2.6 hereof, as a result of which either Holding
Shares or the Exchangeable Shares or both are in any way changed, this Agreement
shall forthwith to the extent practicable be amended and modified as necessary
in order that it shall apply with full force and effect to all new securities
into which Holding Shares or the Exchangeable Shares or both are so changed and
the parties hereto shall execute and deliver an agreement in writing giving
effect to and evidencing such necessary amendments and modifications.

3.3               SEVERABILITY. If any provision of this Agreement is held to be
invalid, illegal or unenforceable, the validity, legality or enforceability of
the remainder of this Agreement shall not in any way be affected or impaired
thereby and this Agreement shall be carried out as nearly as possible in
accordance with its original terms and conditions.

3.4               AMENDMENTS, MODIFICATIONS, ETC. This Agreement may not be
amended or modified except by an agreement in writing executed by Buyco, Holding

with Article 7 of the Exchangeable Share Provisions.

3.5               MINISTERIAL AMENDMENTS. Notwithstanding the provisions of

modify this Agreement in writing for the purposes of:

         (a)      adding to the covenants of either or both parties for the
                  protection of the holders of the Exchangeable Shares;

         (b)      making such amendments or modifications not inconsistent with
                  this Agreement as may be necessary or desirable with respect
                  to matters or questions which, in the opinion of the board of
                  directors of each of Buyco, Holding and Onexco, it may be
                  expedient to make, provided that each such board of directors
                  shall be of the opinion

<PAGE>   6

                                       -6-

                  that such amendments or modifications will not be prejudicial
                  to the interests of the holders of the Exchangeable Shares; or

         (c)      making such changes or corrections which, on the advice of
                  counsel to Buyco, Holding and Onexco, are required for the
                  purpose of curing or correcting any ambiguity or defect or
                  inconsistent provision or clerical omission or mistake or
                  manifest error herein, provided that the boards of directors
                  of each of Buyco, Holding and Onexco shall be of the opinion
                  that such changes or corrections will not be prejudicial to
                  the interests of the holders of the Exchangeable Shares.

3.6               MEETING TO CONSIDER AMENDMENTS. Buyco, at the request of
Holding, shall call a meeting or meetings of the holders of the Exchangeable
Shares for the purpose of considering any proposed amendment or modification
requiring approval pursuant to Section 3.4 hereof. Any such meeting or meetings
shall be called and held in accordance with the by-laws of Buyco and the
Exchangeable Share Provisions. In lieu of calling a meeting of holders of
Exchangeable Shares, with the consent of Holding, any proposed amendment or
modification requiring approval of the holders of Exchangeable Shares pursuant
to Section 3.4 hereof may be given by such holders executing a written
resolution evidencing the approval of such proposed amendment or modification,
which resolution must be signed by all the holders of Exchangeable Shares
entitled to vote on such matter.

otherwise permitted hereunder shall be effective unless made in writing and

2.4 EXERCISE OF THE DEFAULT EXCHANGE RIGHT. Subject to the terms and conditions
herein set forth, a Holder shall be entitled, upon the occurrence and during the
continuance of a Default Event, to exercise the Default Exchange Right with
respect to all but not less than all of the Exchangeable Shares registered in
the name of such Holder on the books of Buyco. To exercise the Default Exchange
Right, the Holder shall deliver to Holding, in person, by courier or by
certified or registered mail, at its principal office or at such other place as
Holding may from time to time designate by written notice to the Holders, the
certificates representing the Holder's Exchangeable Shares, duly endorsed in
blank, and accompanied by such other documents and instruments as Holding may
reasonably require together with:

        (a)  a duly completed form of notice of exercise of the Default Exchange
             Right, contained on the reverse of or attached to the Exchangeable
             Share certificates, stating (i) that the Holder thereby exercises
             the Default Exchange Right so as to require Holding to purchase
             from the Holder that number of Exchangeable Shares specified
             therein, (ii) that such Holder has good title to and owns all such
             Exchangeable Shares to be acquired by Holding free and clear of all
             Liens, (iii) the names in which the certificates representing
             Holding Shares issuable in connection with the exercise of the
             Default Exchange Right are to be issued, and (iv) the names and
             addresses of the Persons to whom such new certificates should be
             delivered; and

        (b)  payment (or evidence satisfactory to Holding of payment) of the
             taxes (if any) payable as contemplated by section 2.6 hereof.

2.5 DELIVERY OF HOLDING SHARES; EFFECT OF EXERCISE.

        (a) Promptly after receipt of the certificates, duly endorsed in blank,
representing the Exchangeable Shares in respect of which the Default Exchange
Right has been exercised and any and all other documents acquired pursuant to
section 2.4 hereof, Holding shall notify Buyco of its receipt of the same and,
subject to section 1.5, Holding shall promptly thereafter deliver or cause to be
delivered to the Holder of such Exchangeable Shares (or to such other Persons,
if any, properly designated by such Holder) the certificates for the number of
Holding Shares issuable in connection with the exercise of the Default Exchange
Right together with payment of the balance, if any, of the purchase price for
such Exchangeable Shares.

        (b) Immediately upon the exercise of the Default Exchange Right, as
provided in section 2.4 hereof, the closing of the transaction of purchase and
sale contemplated by the Default Exchange Right shall be deemed to have
occurred. The Holder of such Exchangeable Shares shall be deemed to have
transferred to Holding all of its right, title and interest in and to such
Exchangeable Shares free and clear of all Liens 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

<PAGE>   6

                                       -6-

the purchase price therefor, unless (i) the requisite number of Holding Shares,
is not allotted, issued and/or delivered by Holding to such Holder (or to such
other Persons, if any, properly designated by such Holder) and (ii) if
applicable, the payment of the balance of the purchase price are not delivered
within five Business Days of the Exchange Date or such cheque is not honoured
when duly presented, in which case the rights of the Holder shall remain
unaffected until such Holding Shares are so allotted, issued and/or delivered by
Holding or such cheque in payment of a cash dividend is delivered or honoured,
as the case may be. Concurrently with such Holder ceasing to be a holder of
Exchangeable Shares, the Holder shall be considered and deemed for all purposes
to be a holder of Holding Shares delivered to such Holder pursuant to the
Default Exchange Right. Holding shall cause the Board of Directors to sanction
or approve any transfer of Exchangeable Shares made pursuant to an exercise of
the Default Exchange Right pursuant to the provisions hereof and such sanction
or approval shall be effective as at the closing of the transaction of purchase
and sale of Exchangeable Shares as provided in this section 2.5.

                Notwithstanding any other provision hereof, Holding shall have
no any obligation to deliver Holding Shares pursuant to the terms hereof prior
to receipt of advice of counsel to Holding that Holding and/or the Holders, as
applicable, have complied with all applicable United States federal and state
securities laws. Among other things, no delivery of Holding Shares shall be made
prior to the delivery by the Holder of a securities representation letter as
reasonably requested by counsel in customary form and substance addressing the
sophistication and investment intent of the Holder and such other matters as are
reasonably requested by counsel to effect compliance with law. Nothing contained
herein shall be deemed to require Holding to register or qualify any Holding
Shares pursuant to the United States Securities Act of 1933, as amended, or the
securities laws of any other jurisdiction. Each Holder, by accepting Holding
Shares pursuant hereto, acknowledges that such Holder may be required to, and
may be required to represent that such Holder will, hold such Holding Shares
indefinitely.

        (c) Upon receipt of any Holding Shares, the Holder shall immediately be
deemed to be a party to that certain Stockholders' Agreement by and among
Holding and the other parties thereto, as such agreement may be hereafter
amended (the "Stockholders Agreement"). The Holder will, promptly upon request
by Holding, execute and deliver a Joinder Agreement in customary form
acknowledging that such Holder is a party to the Stockholders Agreement with the
rights and obligations appurtenant thereto, and such other documents and
instruments as are reasonably requested by Holding and its counsel to ensure
compliance with applicable law and regulation and to otherwise effect the
purposes of these provisions.

2.6 STAMP OR OTHER TRANSFER TAXES. Upon any sale of Exchangeable Shares to
Holding pursuant to the Default Exchange Right, the share certificate or
certificates representing Holding Shares to be delivered in connection with the
payment of the purchase price therefor shall be issued in the name of the Holder
of the Exchangeable Shares so sold or in such names as such Holder may otherwise
direct in writing without charge to the Holder; provided, however, that such
Holder (a)

<PAGE>   7

                                       -7-

shall pay (and neither Holding nor Buyco shall be required to pay) any
documentary, stamp, transfer or other similar taxes that may be payable in
respect of any transfer involved in the issuance or delivery of such shares to a
Person other than such Holder or (b) shall establish to the satisfaction of
Holding and Buyco that such taxes, if any, have been paid.

2.7 NOTICE OF DEFAULT EVENT. Immediately upon the occurrence of a Default Event,
Buyco and Holding shall give written notice thereof to the Holders. Such notice
shall describe the event that has occurred and shall specify that, pursuant to
this Agreement, the Holders are currently entitled, or may become entitled at a
later date, to exercise the Default Exchange Right.

                                   ARTICLE 3
                               CASH EXCHANGE RIGHT

3.1 CASH EXCHANGE EVENT. Following the occurrence of a Cash Exchange Event,
Buyco or Holding, as the case may be, shall satisfy its obligation to deliver
Holding Shares by purchasing each Exchangeable Share in respect of which the
Cash Exchange Event has occurred. Each Shareholder who owns such an Exchangeable
Share shall be obligated to sell such Exchangeable Share in consideration of a
purchase price for each Exchangeable Share in an amount equal to the sum of (i)
the Current Market Price and (ii) an amount equal to the aggregate of all
declared and unpaid cash dividends on such Exchangeable Share through the date
on which the Cash Exchange Event occurred. The purchase price shall be satisfied
by delivery by Buyco or Holding, as the case may be, to such Shareholder of a
cheque in an amount equal to such sum. Upon the delivery of such cheque, the
Shareholder shall cease to be a holder of Exchangeable Shares and shall not be
entitled to exercise any of the rights of Holders in respect thereof.

                                    ARTICLE 4
                     AMENDMENTS AND SUPPLEMENTAL AGREEMENTS

4.1 AMENDMENTS, MODIFICATIONS, ETC. Except as provided for in section 4.2
hereof, this Agreement may not be amended or modified except by an agreement in
writing executed by Buyco, Holding and Holders representing an aggregate of
50% of the issued and outstanding Exchangeable Shares. Any amendment or
modification of this Agreement by Buyco, Holding and the Holders shall bind the
Holders and Buyco, Holding and the Holders shall be entitled to rely on such
amendment or modification for all purposes.

4.2 CHANGES IN THE CAPITAL OF HOLDING OR BUYCO. Notwithstanding section 4.1
hereof, at all times after the occurrence of any capital reorganization,
consolidation, merger, arrangement of Holding or Buyco, as the case may be, or
amalgamation of Holding or Buyco, as the case may be, with or into another
entity, this Agreement shall forthwith be deemed to have been amended and

<PAGE>   8

                                       -8-

modified as necessary in order that it shall apply with full force and effect to
all new securities into which Holding Shares or the Exchangeable Shares or both
are so changed and the parties hereto shall execute and deliver an agreement
giving effect to and evidencing such necessary amendments and modifications.

                                    ARTICLE 5
                                   TERMINATION

                     or

                (ii) the Holders, Buyco and Holding agree in writing to

limitation, any Vendor) that ceases to be a registered holder of Exchangeable
Shares and such Person shall, upon ceasing to be a registered holder of
Exchangeable Shares, be deemed to have ceased to be a party to this Agreement.

                                    ARTICLE 6
                                     GENERAL
