            to purchase from each or any Holder, at any time and from time to
            time all or any part of the Exchangeable Shares held by each such
            Holder; and

      (b)   the Automatic Exchange Rights,

all in accordance with the provisions of this Agreement. BEI hereby acknowledges
receipt from each of the Holders of $1 (and the adequacy thereof) for the grant

2.2 SHARE CERTIFICATES. Exchangeco will cause each certificate representing
Exchangeable Shares to bear an appropriate legend notifying the Holders of (a)
their right to exercise the Exchange Right in respect of the Exchangeable Shares
held by such Holders; and (b) the Automatic Exchange Rights.

2.3 GENERAL EXERCISE OF EXCHANGE RIGHT. The Exchange Right shall be and remain
vested in and exercised by each Holder in respect of the Exchangeable Shares
held by such Holder.

2.4 PURCHASE PRICE FOR THE EXCHANGEABLE SHARES. The purchase price payable by
BEI for each Exchangeable Share to be purchased by BEI under the Exchange Right
shall be an amount per share equal to (a) the Current Market Price of a BEI
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 BEI causing to be sent to such Holder one BEI
Common Share, plus (b) to the extent not paid by Exchangeco, 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. The purchase price for
each such Exchangeable Share so purchased may be satisfied only by BEI issuing

date a cheque for the balance, if any, of the purchase price without interest
but less any amounts withheld pursuant to Section 2.11 (the "EXCHANGE RIGHT

Exchange Right with respect to all or any part of the Exchangeable Shares
registered in the name of such Holder on the books of Exchangeco. To exercise
the Exchange Right, the Holder shall deliver to Exchangeco, in person or by
certified or registered mail, the certificates representing the Exchangeable
Shares that such Holder desires BEI to exchange, duly endorsed in blank and
accompanied by such other documents and instruments as may be required to effect
a transfer of the Exchangeable Shares under the Business Corporations Act
(Ontario) and the by-laws of Exchangeco and such additional documents and
instruments as Exchangeco or BEI may reasonably require together with (a) a duly
completed Notice of Exercise in the form attached hereto as Schedule B and (b)
payment (or evidence satisfactory to Exchangeco and BEI of payment) of the taxes
(if any) payable as contemplated by Section 2.8 of this Agreement. If only a
part of the Exchangeable Shares represented by any certificate or certificates
are to be exchanged by BEI under the Exchange Right, a new certificate for the
balance of such Exchangeable Shares shall be issued to the applicable Holder.

                                      -4-

2.6 DELIVERY OF EXCHANGE RIGHT CONSIDERATION; EFFECT OF EXERCISE. Promptly after
receipt by Exchangeco of the certificate representing the Exchangeable Shares
that the Holder desires BEI to purchase under the Exchange Right (together with
such documents and instruments of transfer and an Exercise Notice and payment of
taxes, if any, or evidence thereof, pursuant to Section 2.8 of this Agreement),
duly endorsed for transfer to BEI, Exchangeco shall notify BEI (with a copy of
such notice sent to the applicable Holder) of its receipt of the same, which
notice to BEI shall constitute exercise of the Exchange Right by the holder of
such Exchangeable Shares, and BEI shall as soon as reasonably practical
thereafter deliver or cause to be delivered to the holder of such Exchangeable
Shares (or to such other persons, if any, properly designated by the applicable
Holder) (i) the number of BEI Shares issuable in connection with the exercise of
the Exchange Right, which shares shall, when issued and delivered against the
surrender of the applicable documents described above, be duly issued, fully
paid and non-assessable and shall be free and clear of all liens, claims or
encumbrances other than (a) liens, claims or encumbrances incurred by such
Holders, (b) rights of first refusal, rights of co-sale or other similar rights
set forth in separate agreements among such Holders, BEI and applicable third
parties, and (c) restrictions on transfer under U.S. state and/or federal
securities laws, or as otherwise required by such laws at the time a transfer is
proposed, and (ii) cheques for the balance, if any, of the total Exchange Right
Consideration therefor, without interest, less any tax required to be deducted
or withheld from the total Exchange Right Consideration by BEI, provided,
however, that no such delivery shall be made (x) unless and until the Holder
requesting the same shall have paid (or provided evidence satisfactory to
Exchangeco of the payment of) the taxes (if any) payable as contemplated by
Section 2.8 of this Agreement and (y) unless either (i) a registration statement
under the Securities Act of 1933 with respect thereto shall be in effect or (ii)
in the opinion of counsel reasonably acceptable in form and substance to BEI,
the proposed delivery shall be exempt from registration under that Act.
Immediately upon the giving of notice by Exchangeco to BEI of the exercise of
the Exchange Right as provided in this Section 2.6, the exchange shall be deemed
to have occurred, and the holder of such Exchangeable Shares shall be deemed to
have transferred to BEI all of its right, title and interest in and to such
Exchangeable Shares 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 the Exchange Right Consideration
therefor, unless the requisite number of BEI Shares together with a cheque for
the balance, if any, of the total Exchange Right Consideration therefor, without
interest, less any tax required to be deducted or withheld from the total
Exchange Right Consideration by BEI is not allotted, issued and delivered by BEI
to such Holder (or to such other persons, if any, properly designated by such
Holder), within five (5) Business Days of the date of the exercise of the
Exchange Right, in which case the rights of the Holder as a holder of the
applicable Exchangeable Shares shall remain unaffected until such BEI Shares are
so allotted, issued and delivered by BEI and any such cheque is so delivered and
paid. Concurrently with such Holder ceasing to be a holder of the applicable
Exchangeable Shares, the Holder shall be considered and deemed for all purposes
to be the holder of the BEI Shares delivered to it pursuant to the Exchange
Right, provided that under no circumstances shall any Holder as a result of the
Exchange Right be deemed to simultaneously hold Exchangeable Shares and BEI
Shares for which such Exchangeable Shares may be exchanged pursuant to the
Exchange Right.

2.7 EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION. In the event that a
Holder has exercised its rights under Article 6 of the Exchangeable Share
Provisions to require Exchangeco to redeem any or all of the Exchangeable Shares
held by the applicable Holder (the "RETRACTED SHARES") and is notified by
Exchangeco pursuant to Section 6.6 of the Exchangeable Share Provisions that
Exchangeco will not be permitted as a result of solvency requirements or other
provisions of applicable law to redeem all such Retracted Shares, provided that
BEI shall not have exercised the Retraction Call Right with respect to the
Retracted Shares and that the Holder of such Retracted Shares has not revoked
the retraction request delivered by such Holder to Exchangeco pursuant to
Section 6.1 of the Exchangeable Share Provisions, the Retraction Request will
constitute and will be deemed to constitute notice from the Holder of the
exercise of the Exchange Right with respect to those Retracted Shares that
Exchangeco is unable to redeem. In any such event, Exchangeco hereby agrees to
immediately notify the Holder of such prohibition against Exchangeco redeeming
all of the Retracted Shares in full.

2.8 STAMP OR OTHER TRANSFER TAXES. Upon any exchange of Exchangeable Shares
pursuant to the Exchange Right or the Automatic Exchange Rights, the share
certificate or certificates representing BEI Shares to be delivered in
connection with the payment of the total consideration therefor shall be issued
in the name of the Holder of the Exchangeable Shares so exchanged or in such
names as such Holder may otherwise direct in writing without charge to the
Holder of the Exchangeable Shares so exchanged, provided, however, that such
Holder (a) shall pay (and neither BEI nor Exchangeco 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 have established to the satisfaction
of BEI and Exchangeco that such taxes, if any, have been paid.

2.9 RESERVATION OF SHARES OF BEI STOCK. BEI hereby represents, warrants and
covenants that it has reserved for issuance and will at all times keep
available, free from pre-emptive and other rights, out of its authorized and
unissued capital stock such number of BEI Shares as are now and may hereafter be
required to enable and permit BEI and Exchangeco to meet their obligations
hereunder, under the Support Agreement (the "SUPPORT Agreement") between BEI,
Exchangeco and the Holders of even date herewith, as the same may be amended
from time to time, and under the Exchangeable Share Provisions. BEI covenants
that it will supply its transfer agent, if any, 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.

2.10 AUTOMATIC EXCHANGE ON LIQUIDATION OF BEI

      (a)   Each of the following events shall give rise to the automatic
            exchange of the Exchangeable Shares (the "AUTOMATIC EXCHANGE
            RIGHTS") as provided in this Section 2.10 (each a "BEI INSOLVENCY
            EVENT"):

            (i)   any determination by the board of directors of BEI to
                  institute voluntary liquidation, dissolution or winding-up
                  proceedings with respect to BEI or to effect any other
                  distribution of assets of BEI among its stockholders for the
                  purpose of winding up its affairs (it being understood that a
                  sale of all or substantially all of the assets of BEI or any
                  merger, consolidation or similar transaction involving BEI
                  shall not, in and of itself, constitute a liquidation,
                  dissolution or winding-up of BEI); and

<PAGE>
                                      -6-

            (ii)  the commencement of any claim, suit, petition or other
                  proceedings with respect to the involuntary liquidation,
                  dissolution or winding up of BEI or to effect any other
                  distribution of assets of BEI among its stockholders for the
                  purpose of winding up its affairs, provided, however, that
                  such shall only be a BEI Insolvency Event if BEI has failed to
                  contest in good faith any such proceeding commenced in respect
                  of BEI within 60 days thereof or if BEI is not successful in
                  any such good faith contestation and all rights of appeal have
                  expired or been exhausted.

      (b)   In order that the Holders will be able to participate on a pro rata
            basis with the holders of BEI Shares in the distribution of assets
            of BEI in connection with a BEI Insolvency Event, immediately prior
            to the effective time of a BEI Insolvency Event all of the then
            outstanding Exchangeable Shares shall be automatically exchanged for
            BEI Shares. To effect such automatic exchange, BEI shall be deemed
            to have purchased, immediately prior to the effective time of a BEI
            Insolvency Event each Exchangeable Share then outstanding and held
            by Holders, and each Holder shall be deemed to have sold the
            Exchangeable Shares held by it at such time, for a purchase price
            per share equal to (a) the Current Market Price of a BEI Share on
            the fifth Business Day prior to the BEI Insolvency Event Effective
            Date, which shall be satisfied in full by BEI issuing to the Holder
            one BEI Share, and (b) to the extent not paid by Exchangeco, an
            additional amount equivalent 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.

      (c)   Immediately prior to the effective time of a BEI Insolvency Event,
            the closing of the purchase and sale transaction contemplated by the
            automatic exchange of Exchangeable Shares for BEI Shares shall be
            deemed to have occurred, and each Holder of Exchangeable Shares
            shall be deemed to have transferred to BEI all of the Holder's
            right, title and interest in and to such Exchangeable Shares and
            shall cease to be a Holder of such Exchangeable Shares and BEI shall
            issue to the Holder the BEI Shares issuable upon the automatic
            exchange of Exchangeable Shares for BEI Shares and shall deliver to
            the Holder a cheque for the balance, if any, of the Unpaid Dividend
            Amount, without interest, less any amounts withheld pursuant to
            section 2.11 hereof, provided however, that no such delivery shall
            be made (x) unless and until the Holder shall have paid (or provided
            evidence satisfactory to Exchangeco of the payment of) the taxes (if
            any) payable as contemplated by Section 2.8 of this Agreement and
            (y) unless either (i) a registration statement under the U.S.
            Securities Act of 1933, as amended, with respect thereto shall be in
            effect, or (ii) in the opinion of counsel reasonably acceptable in
            form and substance to BEI, the proposed delivery shall be exempt
            from registration under that Act. Concurrently with such Holder
            ceasing to be a holder of Exchangeable Shares, the Holder shall be
            considered and deemed for all purposes to be the holder of the BEI
            Shares issued to it pursuant to the automatic exchange of
            Exchangeable Shares for BEI Shares and the certificates held by the
            Holder previously representing the Exchangeable Shares exchanged by
            the Holder with BEI pursuant to such automatic exchange shall
            thereafter be deemed to represent the BEI Shares issued to the
            Holder by BEI pursuant to such automatic exchange. Upon the request
            of a Holder and the surrender by the Holder of Exchangeable Share
            certificates deemed to represent BEI Shares duly endorsed in blank
            and accompanied by such instruments of transfer as BEI may
            reasonably require, BEI shall deliver or cause to be delivered to
            the Holder certificates representing the BEI Shares representing the
            Exchange Right Consideration in respect of such Exchangeable Shares.

                                      -7-

      (d)   If the issuance of any BEI Shares (or other shares or securities
            into which any such shares may be reclassified or changed as
            contemplated by Section 3.3 hereof) to be issued and delivered under
            this Agreement requires exemption from registration under any
            Canadian or United States federal, provincial or state securities or
            other law or regulation before such shares (or such other shares or
            securities) may be issued by BEI and delivered by BEI at the
            direction of Exchangeco to the holder of surrendered Exchangeable
            Shares, subject to obtaining such necessary representations and
            warranties from such holder of surrendered Exchangeable Shares, BEI
            will use reasonable efforts to take all such actions and do all such
            things as are reasonably necessary or desirable on its part to cause
            the issuance of such BEI Shares (or such other shares or securities)
            to be exempt from registration under United States and/or Canadian
            law, as the case may be.

2.11 WITHHOLDING RIGHTS. Exchangeco and BEI shall be entitled to deduct and
withhold from any dividend or consideration otherwise payable to a holder of
Exchangeable Shares (whether pursuant to this Agreement, the Exchangeable Share
Provisions or otherwise) such amounts as Exchangeco or BEI is required to deduct
and withhold with respect to such payment under the Income Tax Act (Canada) (the
"ACT"), the United States Internal Revenue Code of 1986 or any provincial,
state, local or foreign tax law, in each case, as amended. To the extent that
amounts are so withheld, such withheld amounts shall be treated for all purposes
hereof as having been paid to the holder of the Exchangeable Shares in respect
of which such deduction and withholding was made, notwithstanding that such
withheld amounts are actually remitted to the appropriate taxing authority. To
the extent that any such amount so required to be deducted or withheld from any
payment to a Holder exceeds the cash portion of the consideration otherwise
payable to the Holder, BEI shall promptly notify the Holder and unless such
Holder remits the difference in cash to BEI before the tax amount is required to
be remitted to the tax authority, then BEI may sell or otherwise dispose of such
portion of the consideration (including, without limitation, any of the BEI
Common Shares) as is necessary to provide sufficient funds to BEI to enable it
to comply with such deduction or withholding requirement and BEI shall give an
accounting to the Holder with respect thereto and shall notify and pay over to
such Holder any unapplied balance of the net proceeds of such sale that was not
remitted to such tax authority in satisfaction of a deduction or withholding
requirement.

<PAGE>
                                      -8-

      In order to assist BEI in complying with any such deduction and
withholding requirement, the Holder shall, to the extent applicable, deliver to
BEI (i) if such Holder is an individual, trust or corporation, a declaration
sworn by the individual, a trustee or a director, as the case may be, before a
notary or commissioner for oaths to the effect that such Holder, is not and will
not be, on the date of payment, a non-resident of Canada for the purposes of the
Act or (ii) if such Holder is a partnership, a declaration sworn by a general
partner before a notary or commissioner for oaths to the effect that such Holder
is a "Canadian partnership", as defined in the Act.

                                   ARTICLE 3

                                   ARTICLE 4
                                    GENERAL

4.1 TERM OF AGREEMENT. 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 no Exchangeable Shares (or securities or rights convertible into or
exchangeable for or carrying rights to acquire Exchangeable Shares) are held by
any party other than a member of BEI or its affiliates.

4.2 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 the agreement shall be carried out as nearly as possible in accordance with
its original terms and conditions.

TO:    BARNABUS ENERGY, INC. ("BEI")
RE:    Exchangeable Shares in the capital of 2093603 ONTARIO INC. ("EXCHANGECO")

--------------------------------------------------------------------------------

The undersigned holder of exchangeable shares in the capital of Exchangeco (the
"EXCHANGEABLE SHARES") hereby exercises the Exchange Right so as to require BEI
to purchase Exchangeable Shares (the "EXCHANGED SHARES") registered in the name
of the undersigned, subject to the rights, privileges, restrictions and
conditions attached to the Exchangeable Shares (the "EXCHANGEABLE SHARE
PROVISIONS"). All capitalized words used in this Notice of Exercise have the
respective meanings assigned thereto in the Exchange Rights Agreement dated of
even date hereof between BEI and the holders of Exchangeable Shares (the
"EXCHANGE RIGHTS AGREEMENT"). The undersigned presents and surrenders with this
Notice of Exercise a certificate or certificates representing the Exchanged
Shares. THE UNDERSIGNED HEREBY ACKNOWLEDGES THAT A FAILURE TO PRESENT AND
SURRENDER TO EXCHANGECO THE CERTIFICATE OR CERTIFICATES REPRESENTING THE
EXCHANGED SHARES SHALL INVALIDATE THIS NOTICE OF EXERCISE.

The undersigned hereby represents and warrants that the undersigned:

      (a)   has good title to and owns all of the Exchanged Shares free and
            clear of all liens, claims and encumbrances, except as set forth in
            the Exchange Rights Agreement and the Exchangeable Share Provisions;

      (b)   is not a non-resident of Canada for the purposes of the Income Tax
            Act (Canada); and

      (c)   either (1) is not in the United States, is not a U.S. Person and is
            not exchanging such securities for the account or benefit of a U.S.
            Person or a Person in the United States, or (2) will provide BEI
            with an opinion of counsel, of recognized standing reasonably
            satisfactory to BEI, that the issuance of the BEI Common Shares upon
            exchange of the Exchangeable Shares is being made in compliance with
            applicable state securities laws and in accordance with an available
            exemption from registration under the United States Securities Act
            of 1933, as amended (the "1933 ACT"). For the purposes hereof,
            "United States" and "U.S. Person" have the meanings ascribed thereto
            in the 1933 Act.

THE UNDERSIGNED HEREBY ACKNOWLEDGES THE OVERRIDING RIGHT OF BEI TO PURCHASE ALL
BUT NOT LESS THAN ALL OF THE EXCHANGED SHARES FROM THE UNDERSIGNED AND THAT THIS
NOTICE OF EXERCISE IS DEEMED TO BE A REVOCABLE OFFER BY THE UNDERSIGNED TO SELL
THE EXCHANGED SHARES TO BEI IN ACCORDANCE WITH THE EXCHANGE RIGHTS AGREEMENT.

DATED this                  day of                   , 20     .

2.1 COVENANTS REGARDING EXCHANGEABLE SHARES

                  So long as there are outstanding any Exchangeable Shares not
owned by BEI or its Affiliates, BEI shall:

      (a)   not declare or pay any dividend on BEI Shares unless (i) Exchangeco
            shall simultaneously declare or pay, as the case may be, an
            equivalent dividend (as provided for in Section 3 of the Share
            Provisions) on the Exchangeable Shares and (ii) Exchangeco shall
            have sufficient money or other assets or authorized but unissued
            securities available to enable the due declaration and the due and
            punctual payment, in accordance with applicable law, of any such
            dividend on the Exchangeable Shares;

<PAGE>
                                      -3-

      (b)   advise Exchangeco sufficiently in advance of the declaration by BEI
            of any dividend on BEI Shares and take all such other actions as are
            reasonably necessary, in co-operation with Exchangeco, to ensure
            that the respective declaration date, record date and payment date
            for a dividend on the Exchangeable Shares shall be the same as the
            declaration date, record date and payment date for the corresponding
            dividend on BEI Shares;

      (c)   take all such actions and do all such things as are reasonably
            necessary or desirable to enable and permit Exchangeco, in
            accordance with applicable law, to pay and otherwise perform its
            obligations with respect to the satisfaction of the Liquidation
            Amount, the Retraction Price or the Redemption Price in respect of
            each issued and outstanding Exchangeable Share upon a Liquidation
            Distribution, the delivery of a Retraction Request by a holder of
            Exchangeable Shares or a redemption of Exchangeable Shares by
            Exchangeco, as the case may be, including all such actions and all
            such things as are reasonably necessary or desirable to enable and
            permit Exchangeco to deliver or cause to be delivered cash or BEI
            Shares to the holders of Exchangeable Shares in accordance with the
            provisions of Sections 5, 6 or 7, as applicable, of the Share
            Provisions;

      (d)   take all such actions and do all such things as are reasonably
            necessary or desirable to enable and permit BEI, in accordance with
            applicable law, to exercise the Liquidation Call Right, the
            Retraction Call Right or the Redemption Call Right, including all
            such actions and all such things as are necessary or desirable to
            enable and permit BEI to issue and deliver BEI Shares to the holders
            of Exchangeable Shares in accordance with the provisions of Section
            8 of the Share Provisions, provided that in the event that BEI is
            unable to exercise the Liquidation Call Right, the Retraction Call
            Right or the Redemption Call Right, BEI shall take all such actions
            and do all such things as are reasonably necessary or desirable to
            otherwise enable and permit delivery of the BEI Shares to the
            holders of Exchangeable Shares in accordance with the provisions of
            Section 8 of the Share Provisions, provided that nothing in this
            Agreement shall require BEI to register the BEI Shares issuable upon
            the exchange of Exchangeable Shares except as set forth in the
            Registration Rights Agreement;

      (e)   not exercise its vote as a direct or indirect shareholder to
            initiate the voluntary liquidation, dissolution or winding-up of
            Exchangeco nor take any action or omit to take any action that is
            designed to result in the liquidation, dissolution or winding-up of
            Exchangeco;

      (f)   take all such actions and do all such things as are reasonably
            necessary or desirable to enable and permit Exchangeco to perform
            its obligations, in accordance with applicable law, pursuant to the
            exercise of an Exchange Right by holders of Exchangeable Shares,
            including as contemplated in Section 6.6 of the Share Provisions;
            and

<PAGE>
                                      -4-

      (g)   provide holders of Exchangeable Shares with the same information as
            is provided to holders of BEI Shares, such information to be
            provided at the same time and in the same manner as such information
            is provided to holders of BEI Shares.

2.2 SEGREGATION OF FUNDS

                  BEI will cause Exchangeco to deposit a sufficient amount of
funds in a separate account of Exchangeco and segregate a sufficient amount of
such other assets and property as and when necessary to enable Exchangeco to pay
dividends when due and to pay or otherwise satisfy its respective obligations
under Sections 5, 6 or 7 of the Share Provisions, as applicable, and Exchangeco
will use such funds or other assets exclusively to pay such dividends or satisfy
its obligations under Sections 3, 5, 6 or 7 of the Share Provisions.

2.3 RESERVATION OF BEI SHARES

                  BEI hereby represents, warrants and covenants in favour of
Exchangeco and the holders of Exchangeable Shares that BEI has reserved for
issuance and will, at all times while any Exchangeable Shares (other than
Exchangeable Shares held by BEI or its Affiliates) are outstanding, keep
available, free from pre-emptive and other rights, out of its authorized and
unissued capital stock such number of BEI Shares (or other shares or securities
into which BEI Shares may be reclassified or changed as contemplated by Section
2.7) (a) as is equal to the sum of (i) the number of Exchangeable Shares issued
and outstanding from time to time and (ii) the number of Exchangeable Shares
issuable upon the exercise of all rights to acquire Exchangeable Shares
outstanding from time to time (if any) and (b) as are now and may hereafter be
required to enable and permit (x) BEI to meet its obligations under the Exchange
Rights Agreement dated of even date hereof between BEI and holders of
Exchangeable Shares and under any other security or commitment pursuant to which
BEI may now or hereafter be required to issue BEI Shares, (y) BEI to meet its
obligations under the Liquidation Call Right, the Retraction Call Right and the
Redemption Call Right to holders of Exchangeable Shares, and (z) BEI and
Exchangeco to meet their respective obligations hereunder and under the Share
Provisions.

2.4      NOTIFICATION OF CERTAIN EVENTS CONCERNING EXCHANGECO

                  In order to assist and permit BEI to exercise the Liquidation
Call Right, Retraction Call Right and Redemption Call Right, Exchangeco will
notify BEI and the Stockholders' Representative of each of the following events
at the time set forth below:

      (a)   immediately following any determination by the Board of Directors to
            institute voluntary liquidation, dissolution or winding-up
            proceedings with respect to Exchangeco or to effect any other
            distribution of the assets of Exchangeco 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 Exchangeco or Exchangeco
            becoming aware of any threatened or instituted claim, suit, petition
            or other proceedings with respect to the involuntary liquidation,
            dissolution or winding-up of Exchangeco or to effect any other
            distribution of the assets of Exchangeco among its shareholders for
            the purpose of winding up its affairs;

<PAGE>
                                      -5-

      (c)   immediately upon receipt by Exchangeco of a Retraction Request;

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

      (e)   immediately upon the issuance by Exchangeco of any additional
            Exchangeable Shares or rights to acquire Exchangeable Shares (other
            than future issuances contemplated in the Share Purchase Agreement).

2.5 DELIVERY OF BEI SHARES

      (a)   Subject to BEI's exercise of the Liquidation Call Right, the
            Retraction Call Right or the Redemption Call Right, upon notice from
            Exchangeco of any event that requires Exchangeco to cause to be
            delivered BEI Shares to any holder of Exchangeable Shares, BEI
            shall, subject to applicable law, at Exchangeco's request and
            direction forthwith issue and deliver or cause to be delivered to
            the former holder of the surrendered Exchangeable Shares the
            requisite number of BEI Shares to be received by such former holder
            in full satisfaction of Exchangeco's obligations to such former
            holder under the Share Provisions. In consideration of the issuance
            and delivery of such BEI Shares by BEI to such former holder of
            surrendered Exchangeable Shares, Exchangeco shall issue to or to the
            order of BEI one or more common shares in the capital of Exchangeco
            having in aggregate equivalent value to such BEI Shares. All such
            BEI Shares and Exchangeco shares shall be duly authorized and
            validly issued as fully paid and non-assessable and shall be free
            and clear of all liens, claims and encumbrances.

      (b)   In the event that BEI exercises the Liquidation Call Right, the
            Retraction Call Right or the Redemption Call Right, BEI shall
            forthwith issue and deliver or cause to be delivered to the former
            holder of the surrendered Exchangeable Shares the requisite number
            of BEI Shares to be received by such former holder in full
            satisfaction of BEI's obligations to such former holder under the
            Liquidation Call Right, the Retraction Call Right or the Redemption
            Call Right:

2.6 REGISTRATION RIGHTS AGREEMENT

                  So long as there are outstanding any Exchangeable Shares not
owned by BEI or its Affiliates:

      (a)   BEI will not without the prior approval of Exchangeco and the prior
            approval of the holders of the Exchangeable Shares given in
            accordance with Section 11.2 of the Share Provisions:

            (i)   issue or distribute BEI Shares (or securities exchangeable for
                  or convertible into or carrying rights to acquire BEI Shares)
                  to the holders, as a class, of the then outstanding BEI Shares
                  by way of stock dividend or other distribution, other than an
                  issue of BEI Shares (or securities exchangeable for or
                  convertible into or carrying rights to acquire BEI Shares) (A)
                  to holders of BEI Shares who exercise an option to receive
                  dividends in BEI Shares (or securities exchangeable for or
                  convertible into or carrying rights to acquire BEI Shares) in
                  lieu of receiving cash dividends or (B) pursuant to any
                  dividend reinvestment plan or scrip dividend;

            (ii)  issue or distribute rights, options or warrants to the
                  holders, as a class, of the then outstanding BEI Shares
                  entitling them to subscribe for or to purchase BEI Shares (or
                  securities exchangeable for or convertible into or carrying
                  rights to acquire BEI Shares); or

            (iii) issue or distribute to the holders, as a class, of the then
                  outstanding BEI Shares (A) shares or securities of BEI of any
                  class other than BEI Shares (other than those referred to in
                  Section 2.7(a)(i)), (B) rights, options or warrants other than
                  those referred to in Section 2.7(a)(ii), (C) evidences of
                  indebtedness of BEI or (D) assets of BEI or its Affiliates,

            unless the economic equivalent, as determined by BEI in good faith
            and acting reasonably, on a per share basis of such rights, options,
            securities, shares, evidences of indebtedness or other assets is
            issued or distributed simultaneously to holders of the Exchangeable
            Shares provided, however, that the above restrictions shall not
            apply to the distribution of rights pursuant to a stockholders
            rights plan adopted by BEI if the rights are exercisable upon a
            change of control of BEI or upon a person's acquiring a certain
            number of shares of stock of BEI and if such rights will be
            distributed along with BEI stock if BEI exercises its right to call
            the Exchangeable Shares, and further provided that, for greater
            certainty, the above restrictions shall not apply to any securities
            issued or distributed by BEI in order to give effect to and to
            consummate the transactions contemplated by, and in accordance with,
            the Share Purchase Agreement or as otherwise permitted by the
            parties to the Share Purchase Agreement.

<PAGE>
                                      -7-

      (b)   BEI will not without the prior approval of Exchangeco and the prior
            approval of the holders of Exchangeable Shares given in accordance
            with Section 11.2 of the Share Provisions:

            (i)   subdivide, redivide or change the then outstanding BEI Shares
                  into a greater number of BEI Shares; (ii) reduce, combine,
                  consolidate or change the then outstanding BEI Shares into a
                  lesser number of BEI Shares; or

            (iii) reclassify or otherwise change BEI Shares or effect an
                  amalgamation, merger, reorganization or other transaction
                  affecting BEI Shares,

            unless the same or an economically equivalent change, as determined
            by BEI in good faith and acting reasonably, shall simultaneously be
            made to, or in the rights of the holders of, the Exchangeable
            Shares.

      (c)   BEI will ensure that the record date for any event referred to in
            Section 2.7, or, if no record date is applicable for such event, the
            effective date for any such event, is not less than 10 Business Days
            after the date on which such event is declared or announced by BEI
            (with contemporaneous notification thereof by BEI to Exchangeco).

      (d)   Exchangeco agrees that, to the extent required, upon due notice from
            BEI, Exchangeco shall take or cause to be taken such steps as may be
            reasonably necessary for the purposes of ensuring that appropriate
            dividends are paid or other distributions are made by Exchangeco, or
            subdivisions, redivisions or changes are made to the Exchangeable
            Shares, in order to implement the required economic equivalency with
            respect to BEI Shares and the Exchangeable Shares as provided for in
            this Section 2.7.

      (e)   Holders of Exchangeable Shares shall (a) be entitled to receive,
            contemporaneous with receipt by the holders of BEI Shares, the same
            financial and other information and documentation sent by BEI to its
            shareholders in their capacity as shareholders of BEI and (b) be
            entitled to the same access to the books and records of BEI as the
            holders of BEI Shares.

2.8 TENDER OFFERS, ETC.

                  In the event that a tender offer, share exchange offer, issuer
bid, take-over bid or other transaction or series of related transactions
(including any reconstruction, reorganization, merger or consolidation)
affecting BEI Shares (an "OFFER") is proposed by BEI or is proposed to BEI or
its shareholders and is recommended by the Board of Directors of BEI, or is
otherwise effected or to be effected with the consent or approval of the Board
of Directors of BEI, and any Exchangeable Shares are not redeemed by Exchangeco
or purchased by BEI as contemplated by and in compliance with the Share
Provisions, then BEI will use its reasonable efforts expeditiously and in good
faith to take all such actions and do all such things as are reasonably
necessary or desirable to enable and permit holders of Exchangeable Shares to
participate in such Offer to the same extent and on an economically equivalent
basis as the holders of BEI Shares, without discrimination. Without limiting the
generality of the foregoing, BEI will use its reasonable efforts expeditiously
and in good faith (in the case of a transaction by BEI or where BEI is a
participant in the negotiation thereof) to ensure that holders of Exchangeable
Shares may participate in all such Offers without being required to retract the
Exchangeable Shares as against Exchangeco (or, if so required, to ensure that
any such retraction, shall be effective only upon, and shall be conditional
upon, the closing of the Offer and only to the extent necessary to tender or
deposit to the Offer). Nothing herein shall affect the rights of Exchangeco
under the Share Provisions to redeem (or BEI to purchase pursuant to the
Redemption Call Right) the Exchangeable Shares, in the event of a BEI Control
Transaction. In the event that BEI effects a merger for the sole purpose of
changing its jurisdiction of incorporation, then the obligation to the holders
of Exchangeable Shares shall be deemed satisfied if the successor corporation
agrees to assume the obligations of BEI hereunder.

2.9 OWNERSHIP OF VOTING SHARES OF EXCHANGECO

                  Without the prior approval of Exchangeco and the holders of
Exchangeable Shares given in accordance with Section 11.2 of the Share
Provisions, BEI covenants and agrees in favour of Exchangeco and the holders of
Exchangeable Shares that, as long as any of the Exchangeable Shares outstanding
are owned by any Person other than BEI or its Affiliates, BEI will be and shall
remain the direct or indirect beneficial owner of all issued and outstanding
voting shares in the capital of Exchangeco and BEI shall use all commercially
reasonable efforts to ensure that Exchangeco is in good standing under its
jurisdiction of incorporation.

2.10 ACKNOWLEDGEMENT IN FAVOUR OF BEI

                  The holders of Exchangeable Shares acknowledge that BEI has
rights with respect to the Exchangeable Shares as set out in the Share
Provisions, including the Liquidation Call Right, the Retraction Call Right and
the Redemption Call Right, and further acknowledge the overriding nature of such
rights in connection with the liquidation, dissolution or winding-up of
Exchangeco or the retraction or redemption of Exchangeable Shares, as the case
may be, and agree to be bound by any exercise of all or any part of such rights
by BEI as fully and effectively as if those rights and provisions were
incorporated herein in their entirety.

2.11 BEI AND AFFILIATES NOT TO VOTE THEIR EXCHANGEABLE SHARES

                  BEI covenants and agrees that it will appoint and cause to be
appointed proxyholders with respect to all of the Exchangeable Shares held by it
and its Affiliates for the sole purpose of attending each meeting of holders of
Exchangeable Shares in order to be counted as part of the quorum for each such
meeting. BEI further covenants and agrees that it will not, and will cause its
Affiliates not to, exercise any voting rights which may be exercisable by
holders of Exchangeable Shares from time to time pursuant to the Share
Provisions or pursuant to the provisions of the Act (or any successor or other
corporate statute by which Exchangeco may in the future be governed) with
respect to any of the Exchangeable Shares held by it or by its Affiliates in
respect of any matter considered at any meeting of holders of Exchangeable
Shares.

2.12 RULE 10B-18 PURCHASES

                  For certainty, nothing contained in this Agreement shall limit
the ability of BEI to make a "Rule 10b-18 Purchase" of BEI Shares pursuant to
Rule 10b-18 of the U.S. Securities Exchange Act of 1934, as amended, or any
successor provisions thereof.

2.13 CLASS A STOCK

                  BEI shall convene a special meeting of its stockholders on
February 9, 2006 (or if the same is postponed on the date to which it is
postponed) in accordance with the proxy statement filed with the Securities and
Exchange Commission by BEI on January 13, 2006. If the proposal in such proxy
statement to add a class of preferred stock to BEI's articles is approved by the
stockholders with the requisite vote, then BEI will create a series of preferred
shares of BEI (the "CLASS A STOCK"), containing substantially the terms set
forth in Schedule "C" hereto and issue to the holders of Exchangeable Shares one
share of Class A Stock for each Exchangeable Share from time to time
outstanding. So long as there are any Exchangeable Shares outstanding, BEI will
not issue any additional Class A Stock beyond the Class A Stock to be issued
hereunder, and will not amend, alter, change or repeal the terms of the Class A
Stock without the prior approval of the holders of the Exchangeable Shares in
accordance with Section 11.2 of the Share Provisions.

                                   ARTICLE 3
                                 BEI SUCCESSORS

3.1 CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.

                  So long there are any Exchangeable Shares outstanding, unless
a Redemption Date has been established by the Board of Directors of Exchangeco
as a result of a BEI Control Transaction, BEI shall not consummate any BEI
Control Transaction, unless:

      (a)   such other Person or continuing corporation (the "BEI SUCCESSOR") by
            operation of law, becomes, without more, bound by the terms and
            provisions of this Agreement or, if not so bound, executes, prior to
            or contemporaneously with the consummation of such transaction, an
            agreement supplemental hereto and such other instruments (if any) as
            are reasonably necessary or advisable to evidence the assumption by
            the BEI Successor of liability for all moneys payable and property
            deliverable hereunder and the covenant of such BEI Successor to pay
            and deliver or cause to be delivered the same and its agreement to
            observe and perform all the covenants and obligations of BEI under
            this Agreement; and

            interests of holders of Exchangeable Shares.

The Class A shares of the Corporation shall have attached thereto, as a class,
the following rights, privileges, restrictions, and conditions:

                                   SECTION 1

            reconstruction, reorganization, merger or consolidation) or (ii) a
            sale of all or substantially all of the assets of BEI, but for
            greater certainty a "BEI Control Transaction" shall not include the

                  available, such spot exchange rate on such date for such
                  foreign currency expressed in Canadian dollars as may be
                  deemed by the Board of Directors to be appropriate for such
                  purpose.

      (k)   "COMMON SHARES" means common shares in the capital of the
            Corporation, as consolidated or subdivided from time to time, and
            any other securities into which such shares may be reclassified or

      (l)   "CONTROL" has the meaning ascribed thereto in the Act on January 1,
            2006.

      (m)   "CURRENT MARKET PRICE" of a BEI Share on any date means (i) if BEI
            Shares are not listed on such date on an Exchange, such price as
            shall be determined by the Board of Directors, in good faith and
            acting reasonably, based upon the advice of such qualified
            independent financial advisors as the Board of Directors may deem
            appropriate (any such selection, opinion or determination by the
            Board of Directors being conclusive and binding on the Corporation
            and holders of Exchangeable Shares), or (ii) if BEI Shares are
            listed on such date on an Exchange, the Canadian Dollar Equivalent
            of the volume-weighted average of the closing bid and ask prices of

      (n)   "ECONOMICALLY EQUIVALENT" means economically equivalent prior to
            giving any consideration to the tax consequences of the proposed
            event, including without limitation, consequences arising from
            differences in applicable tax laws of various jurisdictions, and for
            greater certainty the requirement for economic equivalence will not

                  is not reasonably practicable to accomplish the business
                  purpose intended by the Exchangeable Share Voting Event, which

                  other commercially reasonable manner that does not result in
                  an Exchangeable Share Voting Event);

            equivalent (as determined by the Board of Directors, in good faith
            and acting reasonably) subdivision of the outstanding Exchangeable

declared on the BEI Shares.

the purposes of Section 3.1(c) hereof and each such determination shall be

distributions declared and paid to date on the BEI Shares shall have been

in this Section 5,a holder of Exchangeable Shares shall be entitled, subject to

other shares ranking junior to the Exchangeable Shares, an amount per
Exchangeable Share (the "LIQUIDATION AMOUNT") equal to (i) the Current Market
Price of a BEI Share on the last Business Day prior to the Liquidation Date
(which, subject to applicable law, shall be satisfied in full by the Corporation
causing to be delivered to such holder one BEI Share for each Exchangeable Share
presented and surrendered by the holder), plus (ii) the Unpaid Dividend Amount,
if any, on any Exchangeable Share held by such holder on any dividend record

5.3 On or promptly after the Liquidation Date, provided that the Liquidation
Call Right has not been exercised by BEI, the Corporation shall cause to be
delivered to the holders of the Exchangeable Shares the Liquidation Amount for
each such Exchangeable Share upon presentation and surrender of the certificates

articles and by-laws of the Corporation and such additional documents and
instruments as the Transfer Agent, the Corporation or BEI may reasonably
require, at the registered office of the Corporation (or at any office of the
Transfer Agent as may be specified by the Corporation by notice to the holders

Exchangeable Shares or by holding for pick-up by the holder at the registered
office of the Corporation or at any office of the Transfer Agent as may be

holders of the Exchangeable Shares shall cease to be holders of such
Exchangeable Shares and shall not be entitled to exercise any of the rights of
holders in respect thereof, other than the right to receive their proportionate
part of the total Liquidation Amount, unless no deposit has be made as described
below and payment of the total Liquidation Amount for such Exchangeable Shares
shall not be made upon presentation and surrender of share certificates in
accordance with the foregoing provisions, in which case the rights of the
holders shall remain unaffected until the total Liquidation Amount has been paid
in the manner hereinbefore provided. The Corporation shall have the right at any
time to deposit or cause to be deposited the total Liquidation Amount, or the
portion of the total Liquidation Amount for such Exchangeable Shares represented
by certificates that have not at the date of such deposit been surrendered by
the holders thereof in connection herewith, in a custodial account with any
chartered bank or trust company in Canada less any amounts withheld on account
of tax required to be deducted and withheld therefrom. Upon the later of such
deposit being made and the Liquidation Date, the rights of the holders of
Exchangeable Shares shall be limited to receiving their proportionate part of
the total Liquidation Amount (in each case less such amounts withheld on account
of tax required to be deducted and withheld therefrom) for such Exchangeable
Shares, against presentation and surrender of the said certificates held by
them, respectively, in accordance with the foregoing provisions.

further distribution of the assets of the Corporation.

Date (which, subject to applicable law, shall be satisfied in full by the
Corporation causing to be delivered to such holder one BEI Share for each
Exchangeable Share presented and surrendered by the holder), plus (ii) the
Unpaid Dividend Amount, if any, on any such Exchangeable Share held by such
holder on any dividend record date which occurred prior to the Retraction Date.

may be specified by the Corporation by notice to the holders of Exchangeable
Shares) the certificate or certificates representing the Exchangeable Shares

liens, claims and encumbrances, together with such other documents and

            by the holder in the Retraction Request, the Retraction Date shall
            be deemed to be the 30th day after the date on which the Retraction
            Request (or immediately following Business Day if such day is not a
            Business Day) is delivered to the Corporation; and

            RIGHT") to purchase all but not less than all the Retracted Shares

            deemed to be a revocable offer by the holder to sell the Retracted
            Shares to BEI in accordance with the Retraction Call Right on the
            terms and conditions set out in Section 6.3 hereof.

6.2 Subject to the exercise by BEI of the Retraction Call Right, upon receipt by
the Corporation or the Transfer Agent in the manner specified in Section 6.1
hereof of a certificate or certificates representing the number of Exchangeable
Shares which the holder desires to have the Corporation redeem, together with a
Retraction Request, and provided that the Retraction Request is not revoked by
the holder in the manner specified in Section 6.7 hereof, the Corporation shall
redeem the Retracted Shares effective at the close of business (Toronto time) on
the Retraction Date and shall cause to be delivered to such holder the total
Retraction Price with respect to such shares, provided that all declared and
unpaid dividends for which the record date has occurred prior to the Retraction
Date shall be paid on the payment date for such dividends, less any amounts
withheld on account of tax required to be deducted and withheld therefrom. If
only a part of the Exchangeable Shares represented by any certificate is
redeemed, a new certificate for the balance of such Exchangeable Shares shall be
issued to the holder at the expense of the Corporation.

6.3 Upon receipt by the Corporation of a Retraction Request, the Corporation
shall immediately provide notice thereof to BEI. In order to exercise the
Retraction Call Right, BEI must notify the Corporation of its determination to
do so (the "BEI CALL NOTICE") within five Business Days of notification to BEI
by the Corporation of the receipt by the Corporation of the Retraction Request.
If BEI does not so notify the Corporation within such five Business Day period,
the Corporation will notify the holder as soon as possible thereafter that BEI
will not exercise the Retraction Call Right. If BEI delivers the BEI Call Notice
within such five Business Day period, and provided that the Retraction Request
is not revoked by the holder in the manner specified in Section 6.7, the
Retraction Request shall thereupon be deemed to be an offer by the holder to
sell the Retracted Shares to BEI in accordance with the Retraction Call Right.
In such event, the Corporation shall not redeem the Retracted Shares and BEI
shall purchase from such holder and such holder shall sell to BEI on the
Retraction Date the Retracted Shares, free and clear of all liens, claims and
encumbrances, for an amount per Retracted Share (the "PURCHASE PRICE") equal to
(i) the Current Market Price of a BEI Share on the last Business Day prior to
the Retraction Date (which shall be satisfied in full by BEI causing to be
delivered to such holder one BEI Share for each Exchangeable Share presented and
surrendered by the holder), plus (ii) the Unpaid Dividend Amount, if any, on
those Retracted Shares held by such holder on any dividend record date which
occurred prior to the Retraction Date. For the purposes of completing a purchase
pursuant to the Retraction Call Right, BEI shall deposit with the Transfer
Agent, on or before the Retraction Date, certificates representing BEI Shares
and a cheque or cheques of BEI payable at par at any branch of the bankers of
BEI representing the Unpaid Dividend Amount, if any, less any amounts withheld
on account of tax required to be deducted and withheld therefrom. Provided that
BEI has complied with the immediately preceding sentence, the closing of the
purchase and sale of the Retracted Shares pursuant to the Retraction Call Right
shall be deemed to have occurred as at the close of business on the Retraction
Date and, for greater certainty, no redemption by the Corporation of such
Retracted Shares shall take place on the Retraction Date. In the event that BEI
does not deliver a BEI Call Notice within such five (5) Business Day period, and
provided that the Retraction Request is not revoked by the holder in the manner
specified in Section 6.7 hereof, the Corporation shall redeem the Retracted
Shares on the Retraction Date and in the manner otherwise contemplated in this
Section 6. As a condition to such purchase, the holder shall deliver such other
documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the Act and the articles and by-laws of the
Corporation and such additional documents and instruments as the Transfer Agent,
the Corporation or BEI may reasonably require, at the registered office of the
Corporation or BEI (or at any office of the Transfer Agent as may be specified
by the Corporation by notice to the holders of the Exchangeable Shares).

                                      -11-

6.4 The Corporation or BEI, as the case may be, shall deliver, or cause the
Transfer Agent to deliver, to the relevant holder, at the address of the holder
recorded in the securities register of the Corporation for the Exchangeable
Shares or at the address specified in the holder's Retraction Request or by
holding for pick-up by the holder at the registered office of the Corporation
(or at any office of the Transfer Agent as may be specified by the Corporation
by notice to the holders of Exchangeable Shares), certificates representing the
BEI Shares (which shares shall be duly issued as fully paid and non-assessable
and shall be free and clear of all liens, claims and encumbrances) registered in
the name of the holder or in such other name as the holder may request, and, if
applicable and on or before the payment date therefor, a cheque payable at par
at any branch of the bankers of the Corporation or BEI, as applicable,
representing the aggregate Unpaid Dividend Amount, if any, in payment of the
total Retraction Price or the total Purchase Price, as the case may be, in each
case less any amounts withheld on account of tax required to be deducted and
withheld therefrom, and such delivery of such certificates and cheques on behalf
of the Corporation or by BEI, as the case may be, or by the Transfer Agent shall
be deemed to be payment of and shall satisfy and discharge all liability for the
total Retraction Price or the total Purchase Price, as the case may be, to the
extent that the same is represented by such share certificates and cheques (plus
any tax deducted and withheld therefrom).

<PAGE>
                                      -12-

6.5 On and after the close of business on the Retraction Date, the holder of the
Retracted Shares shall cease to be a holder of such Retracted 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 Retraction
Price or the total Purchase Price, as the case may be, unless upon presentation
and surrender of certificates in accordance with the foregoing provisions,
payment of the total Retraction Price or the total Purchase Price, as the case
may be, shall not be made as provided in Section 6.4, in which case the rights
of such holder shall remain unaffected until the total Retraction Price or the
total Purchase Price, as the case may be, has been paid in the manner
hereinbefore provided.

6.6 Notwithstanding any other provision of this Section 6, the Corporation shall
not be obligated to redeem Retracted Shares specified by a holder in a
Retraction Request to the extent that such redemption of Retracted Shares would
be contrary to solvency requirements or other provisions of applicable law. If
the Corporation believes that on any Retraction Date it would not be permitted
by any of such provisions to redeem the Retracted Shares tendered for redemption
on such date, and provided that BEI shall not have exercised the Retraction Call
Right with respect to the Retracted Shares, the Corporation shall only be
obligated to redeem Retracted Shares specified by a holder in a Retraction
Request to the extent of the maximum number that may be so redeemed (rounded
down to a whole number of shares) as would not be contrary to such provisions
and shall notify the holder at least two Business Days prior to the Retraction
Date as to the number of Retracted Shares which will not be redeemed by the
Corporation. In any case in which the redemption by the Corporation of Retracted
Shares would be contrary to solvency requirements or other provisions of
applicable law, the Corporation shall redeem Retracted Shares in accordance with
Section 6.2 of these Share Provisions on a pro rata basis and shall issue to
each holder of Retracted Shares a new certificate, at the expense of the
Corporation, representing the Retracted Shares not redeemed by the Corporation
pursuant to Section 6.2 hereof. Provided that the Retraction Request is not
revoked by the holder in the manner specified in Section 6.7 hereof, and
provided that BEI shall not have exercised the Retraction Call Right with
respect to the Retracted Shares, the holder of any such Retracted Shares not
redeemed by the Corporation pursuant to Section 6.2 hereof as a result of
solvency requirements or other provisions of applicable law shall be deemed by
giving the Retraction Request to require BEI to purchase such Retracted Shares
from such holder on the Retraction Date or as soon as practicable thereafter on
payment by BEI to such holder of the Purchase Price for such Retracted Share
(the "EXCHANGE RIGHT"). 6.7 A holder of Retracted Shares may, by notice in
writing given by the holder to the Corporation before the close of business on
the Business Day immediately preceding the Retraction Date, withdraw the
Retraction Request, in which event such Retraction Request shall be null and
void and, for greater certainty, the revocable offer constituted by the
Retraction Request to sell the Retracted Shares to the Corporation or BEI, as
the case may be, shall be deemed to have been revoked.

6.8 BEI shall at any time be entitled to assign all of its rights in this
Section 6 to an Affiliate of BEI provided that such company assumes all of BEI's
obligations under this Section.

                                   SECTION 7
              REDEMPTION OF EXCHANGEABLE SHARES BY THE CORPORATION

7.1 Subject to applicable law and the terms and conditions set forth in this
Section 7, and provided BEI has not exercised the Redemption Call Right, the
Corporation shall on the Redemption Date redeem all but not less than all of the
then outstanding Exchangeable Shares for an amount per Exchangeable Share (the
"REDEMPTION Price") equal to (i) the Current Market Price of a BEI Share on the
last Business Day prior to the Redemption Date (which, subject to applicable
law, shall be satisfied in full by the Corporation causing to be delivered to
each holder of Exchangeable Shares one BEI Share for each Exchangeable Share
presented and surrendered by the holder), plus (ii) the Unpaid Dividend Amount,
if any, on each such Exchangeable Share held by such holder on any dividend
record date which occurred prior to the Redemption Date.

7.2 In any case of a redemption of Exchangeable Shares under this Section 7, the
Corporation shall send or cause to be sent to each holder of Exchangeable Shares
a notice in writing of the redemption by the Corporation or the purchase by BEI
under the Redemption Call Right, as the case may be, of the Exchangeable Shares
held by such holder. In the case of a Redemption Date established in connection
with a BEI Control Transaction, an Exchangeable Share Voting Event or an Exempt
Exchangeable Share Voting Event, the written notice of redemption by the
Corporation or the purchase by BEI under the Redemption Call Right will be sent
on or before the Redemption Date on as many days prior written notice as may be
determined by the Board of Directors of the Corporation to be reasonably
practicable in the circumstances, and in all other cases such notice shall be
sent at least 30 days before the Redemption Date. In any such case, such notice
shall set out the formula for determining the Redemption Price or the Redemption
Call Purchase Price, as the case may be, the Redemption Date and, if applicable,
particulars of the Redemption Call Right.

7.3 On or after the Redemption Date and subject to the exercise by BEI of the
Redemption Call Right, the Corporation shall cause to be delivered to the
holders of the Exchangeable Shares to be redeemed the Redemption Price for each
such Exchangeable Share, upon presentation and surrender at the registered
office of the Corporation (or at any office of the Transfer Agent as may be
specified by the Corporation in such notice) of the certificates representing
such Exchangeable Shares, free and clear of all liens, claims and encumbrances,
together with such other documents and instruments as may be required to effect
a transfer of Exchangeable Shares under the Act and the articles and by-laws of
the Corporation and such additional documents and instruments as the Transfer
Agent, the Corporation or BEI may reasonably require. Payment of the total
Redemption Price for such Exchangeable Shares shall be made by delivery to each
holder on behalf of the Corporation, at the address of the holder recorded in
the securities register of the Corporation or by holding for pick-up by the
holder at the registered office of the Corporation (or at any office of the
Transfer Agent as may be specified by the Corporation in such notice), of
certificates representing BEI Shares (which shares shall be duly issued as fully
paid and non-assessable and shall be free and clear of all liens, claims and
encumbrances) and, if applicable, a cheque of the Corporation payable at par at
any branch of the bankers of the Corporation in payment of any such Unpaid
Dividend Amount, in each case less any amounts withheld on account of tax
required to be deducted and withheld therefrom. On and after the end of the day
of the Redemption Date, the holders of the Exchangeable Shares called for
redemption shall cease to be holders of such Exchangeable Shares and shall not
be entitled to exercise any of the rights of holders in respect thereof, other
than the right to receive their proportionate part of the total Redemption
Price, unless no deposit has been made as described below and payment of the
total Redemption Price for such Exchangeable Shares shall not be made upon
presentation and surrender of certificates in accordance with the foregoing
provisions, in which case the rights of the holders shall remain unaffected
until the total Redemption Price has been paid in the manner hereinbefore
provided. The Corporation shall have the right at any time after the sending of
notice of its intention to redeem the Exchangeable Shares as aforesaid to
deposit or cause to be deposited the total Redemption Price for the Exchangeable
Shares so called for redemption, or of such of the said Exchangeable Shares
represented by certificates that have not at the date of such deposit been
surrendered by the holders thereof in connection with such redemption, in a
custodial account with any chartered bank or trustee named in such notice, less
any amounts withheld on account of tax required to be deducted and withheld
therefrom. Upon the later of such deposit being made and the Redemption Date,
the Exchangeable Shares in respect whereof such deposit shall have been made
shall be deemed to have been redeemed and the rights of the holders thereof
after such deposit or Redemption Date, as the case may be, shall be limited to
receiving their proportionate part of the total Redemption Price for such
Exchangeable Shares, against presentation and surrender of the said certificates
held by them, respectively, in accordance with the foregoing provisions. Upon
such payment or deposit of the total Redemption, less any amounts withheld on
account of tax required to be deducted and withheld therefrom, the holders of
the Exchangeable Shares shall thereafter be considered and deemed for all
purposes to be holders of the BEI Shares delivered to them or the custodian on
their behalf.

                                   SECTION 8
                LIQUIDATION CALL RIGHT AND REDEMPTION CALL RIGHT

8.1 BEI Liquidation Call Right

      (a)   BEI shall have the overriding right (the "LIQUIDATION CALL RIGHT")
            in the event of and notwithstanding the proposed liquidation,
            dissolution or winding-up of the Corporation pursuant to Section 5
            of these Share Provisions, to purchase from all but not less than
            all of the holders of Exchangeable Shares (other than any holder of
            Exchangeable Shares which is an Affiliate of BEI) on the Liquidation
            Date all but not less than all of the Exchangeable Shares held by
            each such holder on payment by BEI of an amount per Exchangeable
            Share (the "LIQUIDATION CALL PURCHASE PRICE") equal to (i) the
            Current Market Price of a BEI Share on the last Business Day prior
            to the Liquidation Date (which shall be satisfied in full by BEI
            causing to be delivered to such holder one BEI Share for each
            Exchangeable Share presented and surrendered by the holder), plus
            (ii) the Unpaid Dividend Amount, if any, on each such Exchangeable
            Share held by such holder on any dividend record date which occurred
            prior to the date of purchase by BEI. In the event of the exercise
            of the Liquidation Call Right by BEI on the Liquidation Date and
            payment by BEI of the Liquidation Call Purchase Price to the holders
            of Exchangeable Shares, the Corporation shall thereafter have no
            obligation to redeem such shares so purchased by BEI.

<PAGE>
                                      -15-

      (b)   To exercise the Liquidation Call Right, BEI must notify the Transfer
            Agent, as trustee for the holders of Exchangeable Shares, of BEI's
            intention to exercise such right at least 30 days before the
            Liquidation Date in the case of a voluntary liquidation, dissolution
            or winding-up of the Corporation and at least five Business Days
            before the Liquidation Date in the case of an involuntary
            liquidation, dissolution or winding-up of the Corporation. The
            Transfer Agent will notify the holders of Exchangeable Shares as to
            whether or not BEI has exercised the Liquidation Call Right, such
            notice to be given forthwith after the expiry of the period during
            which BEI may exercise the Liquidation Call Right, provided that the
            failure by the Transfer Agent to give such notice shall not affect
            the validity of the exercise of the Liquidation Call Right. If BEI
            exercises the Liquidation Call Right, then on the Liquidation Date
            BEI will purchase and the holders will sell all of the Exchangeable
            Shares then outstanding, free and clear of all liens, claims and
            encumbrances, for a price per share equal to the Liquidation Call
            Purchase Price.

      (c)   For purposes of completing the purchase of the Exchangeable Shares
            pursuant to the Liquidation Call Right, BEI shall deposit with the
            Transfer Agent, on or before the Liquidation Date, certificates
            representing the aggregate number of BEI Shares deliverable by BEI
            and a cheque or cheques of BEI payable at par at any branch of the
            bankers of BEI representing the aggregate Unpaid Dividend Amount in
            payment of the total Liquidation Call Purchase Price, in each case
            less any amounts withheld on account of tax required to be deducted
            and withheld therefrom. Provided that BEI has complied with the
            immediately preceding sentence, on and after the Liquidation Date
            the rights of each holder of Exchangeable Shares will be limited to
            receiving such holder's proportionate part of the total Liquidation
            Call Purchase Price payable by BEI upon presentation and surrender
            by the holder of certificates representing the Exchangeable Shares
            held by such holder and the holder shall on and after the
            Liquidation Date be considered and deemed for all purposes to be the
            holder of the BEI Shares to which it is entitled. Upon surrender to
            the Transfer Agent of a certificate or certificates representing
            Exchangeable Shares, free and clear of all liens, claims and
            encumbrances, together with such other documents and instruments as
            may be required to effect a transfer of Exchangeable Shares under
            the Act and the articles and by-laws of the Corporation and such
            additional documents and instruments as the Transfer Agent, the
            Corporation or BEI may reasonably require, the holder of such
            surrendered certificate or certificates shall be entitled to receive
            in exchange therefor, and the Transfer Agent on behalf of BEI shall
            deliver to such holder, certificates representing the BEI Shares to
            which the holder is entitled and a cheque or cheques of BEI payable
            at par at any branch of the bankers of BEI in payment of the
            remaining portion, if any, of the total Liquidation Call Purchase
            Price, in each case less any amounts withheld on account of tax
            required to be deducted and withheld therefrom. If BEI does not
            exercise the Liquidation Call Right in the manner described above,
            on the Liquidation Date the holders of the Exchangeable Shares will
            be entitled to receive in exchange therefor the Liquidation Amount
            otherwise payable by the Corporation in connection with the
            liquidation, dissolution or winding up of the Corporation pursuant
            to Section 5 of these Share Provisions.

<PAGE>
                                      -16-

      (d)   BEI shall at any time be entitled to assign all of its rights in
            this Section 8.1 to an Affiliate of BEI provided that such company
            assumes all of BEI's obligations under this Section.

8.2 BEI Redemption Call Right

      (a)   BEI shall have the overriding right (the "REDEMPTION CALL RIGHT"),
            notwithstanding the proposed redemption of the Exchangeable Shares
            by the Corporation pursuant to Section 7 of these Share Provisions,
            to purchase from all but not less than all of the holders of
            Exchangeable Shares (other than any holder of Exchangeable Shares
            which is an Affiliate of BEI) on the Redemption Date all but not
            less than all of the Exchangeable Shares held by each such holder on
            payment by the Corporation to each holder of an amount per
            Exchangeable Share (the "REDEMPTION CALL PURCHASE PRICE") equal to
            (i) the Current Market Price of a BEI Share on the last Business Day
            prior to the Redemption Date (which shall be satisfied in full by
            BEI causing to be delivered to such holder one BEI Share for each
            Exchangeable Share presented and surrendered by the holder), plus
            (ii) the Unpaid Dividend Amount, if any, on each Exchangeable Share
            held by such holder on any dividend record date which occurred prior
            to the Redemption Date. In the event of the exercise of the
            Redemption Call Right by BEI, each holder shall be obligated to sell
            all the Exchangeable Shares held by the holder to BEI on the
            Redemption Date, free and clear of all liens, claims and
            encumbrances, on payment by BEI to the holder of the Redemption Call
            Purchase Price for each such share, and the Corporation shall
            thereafter have no obligation to redeem such shares so purchased by
            BEI.

      (b)   To exercise the Redemption Call Right, BEI must notify the Transfer
            Agent, as trustee for the holders of Exchangeable Shares, of BEI's
            intention to exercise such right at least 30 days before the
            Redemption Date, except in the case of a redemption occurring as a
            result of a BEI Control Transaction, an Exchangeable Share Voting
            Event or an Exempt Exchangeable Share Voting Event, or such shorter
            period as may be agreed, in writing, by the Corporation, BEI and the
            holders of the Exchangeable Shares, in which case BEI shall so
            notify the Transfer Agent on or before the Redemption Date or, if a
            date has been agreed to as aforesaid, on such agreed-to date. The
            Transfer Agent will notify the holders of Exchangeable Shares as to
            whether or not BEI has exercised the Redemption Call Right forthwith
            after the expiry of the period during which the same may be
            exercised by BEI; provided that the failure by the Transfer Agent to
            give such notice shall not affect the validity of the exercise of
            the Redemption Call Right. If BEI exercises the Redemption Call
            Right, on the Redemption Date BEI will purchase and the holders will
            sell all of the Exchangeable Shares then outstanding, free and clear
            of all liens, claims and encumbrances, for a price per share equal
            to the Redemption Call Purchase Price.

<PAGE>
                                      -17-

      (c)   For the purposes of completing the purchase of the Exchangeable
            Shares pursuant to the Redemption Call Right, BEI shall deposit with
            the Transfer Agent, on or before the Redemption Date, certificates
            representing the aggregate number of BEI Shares deliverable by BEI
            and a cheque or cheques of BEI payable at par at any branch of the
            bankers of BEI representing the aggregate Unpaid Dividend Amount in
            payment of the total Redemption Call Purchase Price, in each case
            less any amounts withheld on account of tax required to be deducted
            and withheld therefrom. Provided that BEI has complied with the
            immediately preceding sentence, on and after the Redemption Date the
            rights of each holder of Exchangeable Shares will be limited to
            receiving such holder's proportionate part of the total Redemption
            Call Purchase Price payable by BEI upon presentation and surrender
            by the holder of certificates representing the Exchangeable Shares
            held by such holder and the holder shall on and after the Redemption
            Date be considered and deemed for all purposes to be the holder of
            the BEI Shares to which it is entitled. Upon surrender to the
            Transfer Agent of a certificate or certificates representing
            Exchangeable Shares, together with such other documents and
            instruments as may be required to effect a transfer of Exchangeable
            Shares under the Act and the articles and by-laws of the Corporation
            and such additional documents and instruments as the Transfer Agent
            may reasonably require, the holder of such surrendered certificate
            or certificates shall be entitled to receive in exchange therefor,
            and the Transfer Agent on behalf of BEI shall deliver to such
            holder, certificates representing the BEI Shares to which the holder
            is entitled and a cheque or cheques of BEI payable at par at any
            branch of the bankers of BEI in payment of the remaining portion, if
            any, of the total Redemption Call Purchase Price, in each case less
            any amounts withheld on account of tax required to be deducted and
            withheld therefrom. If BEI does not exercise the Redemption Call
            Right in the manner described above, on the Redemption Date the
            holders of the Exchangeable Shares will be entitled to receive in
            exchange therefor the Redemption Price otherwise payable by the
            Corporation in connection with the redemption of the Exchangeable
            Shares pursuant to Section 7 of these Share Provisions.

      (d)   BEI shall at any time be entitled to assign all of its rights in

                            PURCHASE FOR CANCELLATION

9.1 Subject to applicable law and the articles and by-laws of the Corporation,
the Corporation may at any time and from time to time offer to purchase for
cancellation all or any part of the outstanding Exchangeable Shares by tender to
all the holders of record of Exchangeable Shares then outstanding of an amount
per Exchangeable Share equal to the Current Market Price of a BEI Share on the
last Business Day prior to the date fixed for such purchase (which, subject to
applicable law, may be satisfied in full by the Corporation causing to be
delivered to such holder one BEI Share for each Exchangeable Share presented and
surrendered by the holder) together with an amount equal to the Unpaid Dividend
Amount. If in response to an invitation for tenders under the provisions of this
Section 9, more Exchangeable Shares are tendered at a price or prices acceptable
to the Corporation than the Corporation is prepared to purchase, the
Exchangeable Shares to be purchased by the Corporation shall be purchased as
nearly as may be pro rata according to the number of shares tendered by each
holder who submits a tender to the Corporation. The holders of Exchangeable
Share desiring to sell hereunder shall surrender to the Transfer Agent a
certificate or certificates representing Exchangeable Shares, free and clear of
all liens, claims and encumbrances, together with such other documents and
instruments as may be required to effect a transfer of Exchangeable Shares under
the Act and the articles and by-laws of the Corporation and such additional
documents and instruments as the Transfer Agent, the Corporation or BEI may
reasonably require. If only part of the Exchangeable Shares represented by any
certificate shall be purchased, a new certificate for the balance of such shares
shall be issued at the expense of the Corporation. All payments to be made under
this Section 9 may be subject to withholdings on account of tax required to be
deducted and withheld therefrom.

change or remove any right, privilege, restriction or condition attaching to the

not less than two-thirds (2/3) of the votes cast on such resolution at a meeting
of holders of Exchangeable Shares duly called and held at which the holders of
at least two-thirds (2/3) of the outstanding Exchangeable Shares at that time

to the Retraction Call Right referred to below, the undersigned desires to have
the Corporation redeem in accordance with Section 6 of the Share Provisions:

                  be less than 30 days nor more than 45 days after the date upon
                  which this notice is delivered to the Corporation. If no such
                  Business Day is specified above, the Retraction Date shall be
                  deemed to be the 30th day after the date on which this notice
                  is delivered to the Corporation (or immediately following

Share Provisions.

provisions or other provisions of applicable law, the Corporation is unable to
redeem all Retracted Shares and if BEI shall not have exercised the Retraction
Call Right with respect to the Retracted Shares, the undersigned will be deemed
to have exercised the Exchange Right (as defined in the Share Provisions) so as
to require BEI to purchase the unredeemed Retracted Shares.

Corporation and BEI that the undersigned:

                                  SCHEDULE "C"

                        FORM OF CLASS A STOCK PROVISIONS

                  1. DESIGNATION. ___ shares of the authorized and unissued
Preferred Stock of the Corporation are hereby designated "Class A Stock" with
the following rights, preferences, powers, privileges and restrictions,
qualifications and limitations.

                  2. VOTING. The holder of each share of Class A Stock shall be
entitled to one vote per share of Class A Stock on each action on which holders
of Common Stock of the Corporation are entitled to vote (subject to appropriate
adjustment in the event of any stock dividend, stock split, combination or other
similar recapitalization affecting the number of issued and outstanding shares
of Common Stock or Class A Stock).

                  3. NO DIVIDENDS; NO PAYMENTS UPON LIQUIDATION. The holders of
the Class A Stock shall not be entitled to receive and shall not be paid (i) any
dividends or distributions or (ii) any amounts upon the liquidation, dissolution
or winding up of the Corporation.

                  4. REDEMPTION OF CLASS A STOCK. Upon the acquisition of Class
A shares ("EXCHANGEABLE SHARES") of 2093603 Ontario Inc. (the "CANADIAN
SUBSIDIARY") from a holder by either the Canadian Subsidiary or the Corporation
(such date, the "CLASS A REDEMPTION DATE"), simultaneously with such acquisition
the Corporation shall automatically redeem from such holder a like number of
shares of Class A Stock (subject to adjustment to reflect any stock split, stock
dividend, reverse stock split or similar corporate event affecting the
Exchangeable Shares or the Class A Stock) at a redemption price per share equal
to $0.0001 (subject to adjustment to reflect any stock split, stock dividend,
reverse stock split or similar corporate event affecting the Class A Stock) (the
"CLASS A REDEMPTION PRICE"). On or before the applicable Class A Redemption
Date, each holder of shares of Class A Stock to be redeemed on such Class A
Redemption Date shall surrender the certificate or certificates representing
such shares to the Corporation, if the Corporation is not already holding such
certificate or certificates in escrow (or, if such registered holder alleges
that any such certificate has been lost, stolen or destroyed, a lost certificate
affidavit and agreement reasonably acceptable to the Corporation to indemnify
the Corporation against any claim that may be made against the Corporation on
account of the alleged loss, theft or destruction of such certificate), and
thereupon the Class A Redemption Price for such shares shall be payable to the
order of the person whose name appears on such certificate or certificates as
the owner thereof within thirty (30) days of the later of (a) such Class A
Redemption Date and (b) the surrender of such certificate or certificates, or
lost certificate affidavit and agreement, to the Corporation. If, on the
applicable Class A Redemption Date, the certificates evidencing any Class A
Stock so called for redemption shall not have been surrendered for redemption,
all rights with respect to such shares, including all voting rights, shall
nonetheless terminate on the Class A Redemption Date, except for the right of
the holders to receive the Class A Redemption Price without interest as provided
in the foregoing sentence. In all cases, upon the automatic redemption of shares
of Class A Stock on each applicable Class A Redemption Date, such shares shall
be cancelled, retired and eliminated from the shares which the Corporation is
authorized to issue.

                  5. TRANSFERABILITY. Shares of Class A Stock shall not be
transferred without the prior written consent of the Corporation, which the
Corporation may withhold at its sole discretion.
