SECTION 2.01 - ISSUE OF WARRANTS

         4,072,000 Warrants entitling the holders thereof to acquire, on the
terms and subject to the conditions herein provided, 4,072,000 Exchangeable
Shares (or, in the circumstances described in Article Four, 4,438,480
Exchangeable Shares), or such other kind and amount of Underlying Shares as may
be herein provided, are hereby created and authorized to be issued hereunder

SECTION 2.02 - FORM AND TERMS OF WARRANTS

(1)      The certificates representing the Warrants (the "WARRANT CERTIFICATES")
         shall be substantially in the form set out in Schedule A hereto, shall
         be dated as of the date hereof (regardless of their actual date of
         issue) and shall have such distinguishing letters and numbers as the
         Corporation may prescribe with the approval of the Trustee. Warrant
         certificates may be engraved, lithographed, printed or typewritten or

         approval of the Trustee may determine.

(2)      Each Warrant authorized to be issued hereunder shall entitle the holder
         thereof to acquire (subject to subsection 5.01(2)), at no additional
         cost, one Exchangeable Share (or, in the circumstances described in
         Article Four, 1.09 Exchangeable Shares) or such other kind and amount
         of Underlying Shares as may be provided in accordance with the
         provisions of this Indenture.

(3)      Fractional Warrants shall not be issued or otherwise provided for.

(5)      All Warrant certificates shall have typed thereon the following legend:

         "This Special Warrant, the Exchangeable Shares issuable upon exercise
         hereof and the shares of Common Stock, par value US$0.01 per share, of
         The Learning

<PAGE>   15
                                     - 10 -


         Company, Inc. (the "Common Stock") issuable upon exchange of the
         Exchangeable Shares have not been registered under the Securities Act
         of 1933, as amended, of the United States of America (the "U.S.
         Securities Act"); the Special Warrant, the Exchangeable Shares and the
         Common Stock may not be offered, sold or otherwise transferred within
         the United States or to, or for the account or benefit of, any U.S.
         person (as such terms are defined in Regulation S promulgated under the
         U.S. Securities Act) unless such offer, sale or transfer is covered by
         or made pursuant to an effective registration statement under the U.S.
         Securities Act or pursuant to an exemption from registration under the
         U.S. Securities Act, nor may any Special Warrant or Exchangeable Share
         be offered, sold or otherwise transferred within the United States or
         to, or for the account or benefit of, any U.S. person unless the
         issuance of the Common Stock is registered under an effective
         registration statement under the U.S. Securities Act or an exemption
         from registration under the U.S. Securities Act is available for the
         exchange of the Exchangeable Shares."

SECTION 2.03 - SIGNING OF WARRANT CERTIFICATES

         The Warrant certificates shall be signed by any of the chairman, chief
executive officer, president, secretary or a vice-president of the Corporation
and may but need not be under the corporate seal of the Corporation or a
reproduction thereof. The signature of such officer may be mechanically
reproduced in facsimile and Warrant certificates bearing such facsimile
signatures shall be binding upon the Corporation as if they had been manually
signed by such officer. Notwithstanding that the person whose manual or
facsimile signature appears on any Warrant certificate as such officer may no
longer hold office at the date of issue of such Warrant certificate or at the
date of certification or delivery thereof, any Warrant certificate signed as
aforesaid shall, subject to Section 2.04, be valid and binding upon the
Corporation and the registered holder thereof shall be entitled to the benefits
of this Indenture.

SECTION 2.04 - CERTIFICATION BY THE TRUSTEE

(1)      No Warrant certificate shall be issued or, if issued, shall be valid
         for any purpose or entitle the registered holder to the benefit hereof
         or thereof until it has been certified by manual signature by or on
         behalf of the Trustee in the form of the Warrant certificate set out in
         Schedule A and such certification by the Trustee upon any Warrant
         certificate shall be conclusive evidence as against the Corporation
         that the Warrant certificate so certified has been duly issued
         hereunder and the holder is entitled to the benefits hereof.

(2)      The certification of the Trustee on Warrant certificates issued
         hereunder shall not be construed as a representation or warranty by the
         Trustee as to the validity of this Indenture or the Warrants (except
         the due certification thereof) and the Trustee shall in no respect be
         liable or

<PAGE>   16
                                     - 11 -


answerable for the use made of the Warrants or any of them or of the
consideration therefor except as otherwise specified herein.

SECTION 2.05 - WARRANTHOLDER NOT A SHAREHOLDER, ETC.

         The holding of a Warrant shall not be construed as conferring upon a
Warrantholder any right or interest whatsoever as a Shareholder nor entitle the
holder to any right or interest in respect thereof except as expressly provided
herein and in the Warrants.

SECTION 2.06 - ISSUE IN SUBSTITUTION FOR LOST WARRANT CERTIFICATES

(1)      In the case where any Warrant certificate shall become mutilated or be
lost, destroyed or stolen, the Corporation, subject to applicable law and
subsection 2.06(2), shall issue and thereupon the Trustee shall certify and
deliver a new Warrant certificate of like tenor as the one mutilated, lost,
destroyed or stolen in exchange for and in place of and upon cancellation of
such mutilated Warrant certificate, or in lieu of and in substitution for such
lost, destroyed or stolen Warrant certificate, and the substituted Warrant
certificate shall be in a form approved by the Trustee and shall entitle the
holder to the benefits hereof and shall rank equally in accordance with its
terms with all other Warrant certificates issued or to be issued hereunder.

(2)      The applicant for the issue of a new Warrant certificate pursuant to
this Section 2.06 shall bear the cost of the issue thereof and in case of loss,
destruction or theft shall furnish to the Corporation and to the Trustee, as a
condition precedent to the issue thereof, such evidence of ownership and of the
loss, destruction or theft of the Warrant certificate so lost, destroyed or
stolen as shall be satisfactory to the Corporation and to the Trustee in their
sole discretion, and such applicant may also be required to furnish an indemnity
bond or security in amount and form satisfactory to the Corporation and the
Trustee in their sole discretion and shall pay the reasonable charges of the
Corporation and the Trustee in connection therewith.

SECTION 2.07 - WARRANTS TO RANK PARI PASSU

         All Warrants shall rank pari passu, whatever may be the actual date of
issue of Warrant certificates evidencing the same.

SECTION 2.08 - REGISTERS FOR WARRANTS

(1)      The Corporation hereby appoints the Trustee as transfer agent and
registrar of the Warrants. The Corporation may appoint hereafter, with the
consent of the Trustee, one or more additional transfer agents and/or registrars
of the Warrants.

<PAGE>   17
                                     - 12 -


(2)      The Corporation shall cause to be kept by the Trustee at its principal
office in the City of Toronto (a) a register of Warrantholders in which shall be
entered the names and addresses of the Warrantholders and of the number of
Warrants held by them and (b) a register of transfers of Warrants in which shall
be entered the date and other particulars of each transfer of Warrants.

(3)      No transfer of a Warrant shall be valid unless made by:

    (a)  the holder or his executors, administrators or other legal
         representatives or his or their attorney duly appointed by an
         instrument in writing in form and execution satisfactory to the Trustee
         with signatures guaranteed by a Canadian chartered bank, a Canadian
         trust company or a member firm of The Toronto Stock Exchange; or

    (b)  the liquidator of, or a trustee in bankruptcy for, a Warrantholder,

upon compliance with such reasonable requirements as the Trustee and the
Corporation may prescribe (including, without limitation, the requirement to
provide evidence of satisfactory compliance with applicable Securities Laws),
and unless recorded on the register of transfers maintained by the Trustee
pursuant to clause 2.08(2)(b), nor until all stamp taxes or governmental or
other charges arising by reason of such transfer have been paid.

(4)      In all cases, no transfer of a Warrant shall be valid if made to, and
no Warrant may be transferred to, a person resident in any Province of Canada
other than a Designated Province.

SECTION 2.09 - TRANSFEREE ENTITLED TO REGISTRATION

         The transferee of a Warrant shall be entitled to have his name entered
on the register of holders as the owner of such Warrant free from all equities
or rights of set-off or counterclaim between the Corporation and the transferor
or any previous holder of such Warrant, save in respect of equities of which the
Corporation or the transferee is required to take notice by statute or by order
of a court of competent jurisdiction after the transfer form attached to the
Warrant and any other form of transfer acceptable to the Trustee (which may
include the obligation of the transferee to provide representations and
warranties equivalent to those contained in Schedule C of the Subscription
Agreements) is duly completed and the Warrant is lodged with the Trustee and
upon compliance with all other conditions in that regard required by this
Indenture or by law.

SECTION 2.10 - REGISTERS OPEN FOR INSPECTION

         The registers hereinbefore referred to shall be open during normal
business hours for inspection by the Corporation, the Trustee or any
Warrantholder. The Trustee shall furnish the Corporation with a list of the

<PAGE>   18
                                     - 13 -


holders kept by the Trustee and showing the number of Underlying Shares that
might be acquired upon the exercise of the Warrants held by each such holder
from time to time when requested to do so in writing by the Corporation.

SECTION 2.11 - EXCHANGE OF WARRANTS

(1)      Warrant certificates may be exchanged for Warrant certificates in any
other authorized denomination representing in the aggregate the same number of
Warrants upon compliance with the reasonable requirements of the Trustee. The
Corporation shall sign and the Trustee shall certify, in accordance with
Sections 2.03 and 2.04, all Warrant certificates necessary to carry out the
exchanges contemplated herein.

(2)      Warrant certificates may be exchanged only at the principal office of
the Trustee in the City of Toronto or at any other place that is designated by
the Corporation with the approval of the Trustee. Any Warrant certificates
tendered for exchange shall be surrendered to the Trustee and cancelled.

(3)      No charge will be levied by the Corporation or the Trustee upon a
presenter of a Warrant certificate pursuant to this Indenture for the transfer
of any Warrant or for the exchange of any Warrant certificate, however
reimbursement of the Trustee or the Corporation for any and all taxes or
governmental or other charges required to be paid shall be made by the person
requesting such exchange as a condition precedent to such exchange.

SECTION 2.12 - OWNERSHIP OF WARRANTS

         The Corporation and the Trustee shall deem and treat the registered
holder of any Warrant certificate as the absolute owner of the Warrant
represented thereby for all purposes, and the Corporation and the Trustee shall
not be affected by any notice or knowledge to the contrary except where the
Corporation or the Trustee is required to take notice by statute or by order of
a court of competent jurisdiction. A Warrantholder shall be entitled to the
rights evidenced by such Warrant free from all equities or rights of set-off or
counterclaim between the Corporation and the original or any intermediate holder
thereof and all persons may act accordingly and the receipt by any such
Warrantholder of Underlying Shares pursuant to such Warrant shall be a good
discharge to the Corporation and the Trustee for the same and neither the
Corporation nor the Trustee shall be bound to inquire into the title of any such
holder except where the Corporation or the Trustee is required to take notice by
statute or by order of a court of competent jurisdiction.

SECTION 2.13 - ADJUSTMENT OF EXERCISE RIGHTS

         Subject to Sections 2.14 and 2.15, if at any time after the date hereof
and prior to the Time of Expiry, and provided any Warrants remain outstanding,
there shall occur:

    (a)  a reclassification of the Exchangeable Shares outstanding at any time
         or a change of the Exchangeable Shares into other shares or securities
         or a subdivision or consolidation of the Exchangeable Shares into a
         greater or lesser number of shares or any other capital reorganization;

    (b)  a consolidation, amalgamation or merger of the Corporation with or into
         any other person (other than a consolidation, amalgamation or merger
         that does not result in any reclassification of the outstanding
         Exchangeable Shares or a change of the Exchangeable Shares into other
         shares or securities);

    (c)  a transfer of the undertaking or assets of the Corporation as an
         entirety or substantially as an entirety to another corporation or
         other entity; or

    (d)  an issue or distribution to the holders of all or substantially all the
         Corporation's outstanding Exchangeable Shares of securities of the
         Corporation, including rights, options or warrants to acquire
         Exchangeable Shares, or securities convertible into or exchangeable for
         Exchangeable Shares or any property or assets and any evidences of
         indebtedness, excluding dividends (other than stock dividends) or other
         distributions made in the ordinary course by the Corporation and
         excluding securities issued pursuant to a stock option or stock
         purchase plan of the Corporation or other stock acquisition
         arrangements of the Corporation in effect as of the date hereof,

any of such events being called a "CAPITAL REORGANIZATION", the holder of any
Warrant who thereafter shall exercise his right to acquire Underlying Shares
shall be entitled to receive, and shall accept for no extra cost, in lieu of the
number of Underlying Shares that he was theretofore entitled upon such exercise,
the kind and amount of Exchangeable Shares or other shares, securities or
property which such holder would have received had he been the registered holder
of the Underlying Shares in respect of his Warrants on such effective date or
record date, as the case may be. If determined appropriate by the Corporation,
acting reasonably, appropriate adjustments shall be made as a result of any such
Capital Reorganization in the application of the provisions set forth
hereinafter in this Article Two with respect to the rights and interests
thereafter of Warrantholders with the result that the provisions set forth
hereinafter in this Article Two shall thereafter correspondingly be made
applicable as nearly as may be reasonably possible in relation to any other
shares, securities or property thereafter deliverable upon the exercise of any
Warrant. Any such adjustments shall be made by and set forth in an indenture
supplemental hereto approved by the

<PAGE>   20
                                     - 15 -


directors and the Trustee and shall for all purposes be conclusively deemed to
be an appropriate adjustment absent manifest error.

SECTION 2.14 - ADJUSTMENT RULES

(1)      The adjustments provided for in Section 2.13 are cumulative and shall
apply (without duplication) to successive Capital Reorganizations or other
events resulting in any adjustment under the provisions of Section 2.13 provided
that, notwithstanding any other provision of this Article Two, no adjustment
shall be made in the number of Underlying Shares that may be acquired on the
exercise of a Warrant unless it would result in a change of at least one
one-hundredth of an Underlying Share (provided, however, that any adjustments
that by reason of this subsection 2.14(1) are not required to be made shall be
carried forward and taken into account in any subsequent adjustment).

(2)      If any question shall arise with respect to the adjustments provided
for in this Article Two, such question, absent manifest error and subject to the
prior consent of The Toronto Stock Exchange, shall be conclusively determined by
a firm of chartered accountants appointed by the Corporation (who may be the
Corporation's auditors) and acceptable to the Trustee, acting reasonably; such
chartered accountants shall have access to all necessary records of the
Corporation and such determination shall be binding upon the Corporation, the
Trustee and the Warrantholders, absent manifest error. In the event that any
such determination is made, the Corporation shall deliver a certificate to the
Trustee describing such determination and confirming such consent.

(3)      No adjustment in the number of Underlying Shares that may be acquired
upon exercise of a Warrant shall be made in respect of any event described in
Section 2.13 if Warrantholders are entitled to participate in such event on the
same terms mutatis mutandis as if Warrantholders had exercised their Warrants
prior to or on the effective date or record date of such event, such
participation being subject to the prior consent of The Toronto Stock Exchange.

(4)      In case the Corporation after the date of this Indenture shall take any
action affecting the Exchangeable Shares other than an action described in this
Article Two, which in the opinion of the directors would materially affect the
rights of Warrantholders, the number of Underlying Shares that may be acquired
upon exercise of a Warrant shall be adjusted in such manner and at such time, by
action of the directors, in their sole discretion as they may determine to be
equitable in the circumstances, provided that no such adjustment will be made
unless prior approval of The Toronto Stock Exchange and any other stock exchange
on which the Exchangeable Shares are listed for trading or quoted has been
obtained. Failure of the directors to make such an adjustment shall be prima
facie evidence that the directors have determined that it is equitable to make
no adjustment in the circumstances.

<PAGE>   21
                                     - 16 -


(5)      the Corporation shall set a record date to determine the holders of the
Exchangeable Shares for the purpose of entitling them to receive any issuance or
distribution or for the issuance of any rights, options or warrants and shall
thereafter and before such distribution or issuance to such shareholders abandon
its plan to make such distribution or issuance, then no adjustment in the number
of Underlying Shares that may be acquired upon exercise of any Warrant shall be
required by reason of the setting of such record date.

(6)      The Corporation shall not be required to issue fractional securities in
satisfaction of its obligations hereunder. If any fractional interest in an
Underlying Share would, except for the provisions of this subsection, be
deliverable upon the exercise of a Warrant, the Corporation shall make a cash
payment equal to the fair value of the fraction of such Underlying Share not so
issued as determined by the board of directors in its sole discretion, acting
reasonably.

SECTION 2.15 - PROCEEDINGS PRIOR TO ANY ACTION REQUIRING ADJUSTMENT

         As a condition precedent to the taking of any action which would
require an adjustment pursuant to Section 2.13, the Corporation shall take any
action that, in the opinion of counsel, may be necessary in order that the
Corporation may validly and legally issue as fully paid and non-assessable all
the Underlying Shares that the holders of the Warrants are entitled to receive
on the full exercise thereof in accordance with the provisions hereof.

SECTION 2.16 - NOTICE OF ADJUSTMENT OF EXERCISE RIGHTS

(1)      At least seven days prior to the effective date or record date, as the
case may be, of any event that requires or that may require an adjustment in any
of the exercise rights pursuant to any of the Warrants, including the number of
Underlying Shares that may be acquired upon the exercise thereof, the
Corporation shall:

    (a)  file with the Trustee a certificate of the Corporation specifying the
         particulars of such event and, if determinable, the required adjustment
         and the computation of such adjustment; and

    (b)  give notice to the Warrantholders of the particulars of such event and,
         if determinable, the required adjustment.

(2)      In case any adjustment for which a notice in subsection 2.16(1) has
been given is not then determinable, the Corporation shall promptly after such
adjustment is determinable:

    (a)  file a certificate of the Corporation with the Trustee showing how such
         adjustment was computed; and

<PAGE>   22
                                     - 17 -


    (b)  give notice to the Warrantholders of the adjustment.

(3)      The Trustee may act and rely for all purposes upon any certificates and
any other documents filed by the Corporation pursuant to this Section 2.16.

SECTION 2.17 - NO DUTY TO INQUIRE, LIABILITY

(1)      Except as provided in Section 9.02, the Trustee shall not at any time
be under any duty or responsibility to any Warrantholder to determine whether
any facts exist which may require any adjustment contemplated by Sections 2.13
and 2.14 or with respect to the nature or extent of any such adjustment when
made or with respect to the method employed in making the same.

(2)      In case of any adjustment contemplated by Sections 2.13 and 2.14, the
Corporation shall:

    (a)  be accountable with respect to the validity or value (or the kind or
         amount) of any securities or property which may at any time be issued
         or delivered upon the exercise or deemed exercise of any Warrant; and

    (b)  be responsible for any failure to make any cash payment or to issue,
         transfer or deliver security certificates upon the surrender of any
         Warrant for the purpose of exercise or deemed exercise, or to comply
         with any of the covenants contained in this Article Two.

           ESCROW OF NET PROCEEDS AND REDEMPTION OF SPECIAL WARRANTS


SECTION 3.01 - DEPOSIT OF NET PROCEEDS IN ESCROW

         The Corporation hereby deposits the Net Proceeds in escrow with the
Trustee, and the Trustee hereby acknowledges receipt thereof. The Corporation
hereby irrevocably authorizes and instructs the Trustee to hold and deal with
the Net Proceeds in trust for the benefit of the Warrantholders and the
Corporation as their respective interests may appear and in accordance with and
subject to the provisions of this Article.


<PAGE>   23
                                     - 18 -


SECTION 3.02 - INVESTMENT OF NET PROCEEDS

         The Net Proceeds deposited with the Trustee hereunder, pending any
release or application thereof as required in accordance with the provisions of
this Article, shall be invested by the Trustee in its name in Permitted
Investments in accordance with any written directions of the Corporation from
time to time given to the Trustee or, in the absence of any such directions,
shall be invested by the Trustee in its name in accordance with Section 10.04.

SECTION 3.03 - RELEASE OF ESCROWED FUNDS TO THE CORPORATION

(1)      If the Corporation satisfies the Transaction Support Condition or
obtains Shareholder Approval, in each case, to be evidenced by the execution and
delivery to the Trustee by the Corporation and Griffiths McBurney & Partners on
behalf of the Underwriters of the Release Certificate, prior to the
Qualification Deadline, the Trustee shall release the Escrowed Funds to the
Corporation, for the purpose of completing the acquisition of Creative Wonders.

(2)      If the Escrowed Funds are not released to the Corporation pursuant to
subsection 3.03(1), the Trustee shall release the Escrowed Funds to the
Corporation on the first to occur of (a) the last Clearance Date to occur in the
Designated Provinces and (b) the Qualification Deadline, provided only that the
Corporation has obtained Transaction Approval on or before such date. The
occurrence of such date and the satisfaction of such proviso shall be
conclusively evidenced by the execution and delivery to the Trustee of a
certificate of an officer of the Corporation to such effect.

SECTION 3.04 - REDEMPTION OF WARRANTS

(1)      If the Corporation fails to obtain Transaction Approval on or prior to
the Qualification Deadline, the Corporation shall forthwith after such failure
(but in any event within five business days following the Qualification
Deadline) give notice thereof to each of the Warrantholders and to the Trustee
(the date of such notice being hereafter referred to as the "Notice Date"). Such
notice shall specify (i) that the Corporation shall be deemed to have redeemed
all of the Warrants on the Notice Date, and that each Warrantholder shall be
deemed to have sold his Warrants to the Corporation on the Notice Date and, in
connection therewith, to have surrendered his Warrants for cancellation, in each
case, for a redemption price per Warrant equal to the Redemption Amount and (ii)
that the Trustee shall, not later than three Business Days after the Notice
Date, send by ordinary mail to each such Warrantholder, or to such person as
such holder may otherwise specify by written notice to the Trustee prior to such
mailing, at the address of such holder or, if so specified, of such person, a
cheque or bank draft made payable to or to the order of such holder or, if so
specified, such person, in an aggregate amount equal to the Redemption Amount
for each unexercised Warrant held by such Warrantholder less applicable
withholding taxes, if any.

<PAGE>   24
                                     - 19 -


(2)      If the Corporation fails to obtain Transaction Approval on or prior to
the Qualification Deadline as contemplated by subsection 3.04(1), on the Notice
Date the Corporation shall redeem, and shall be deemed to have redeemed, all of
the Warrants outstanding on such date and each Warrantholder shall sell, and be
deem to have sold, his Warrants to the Corporation on such date and, in
connection therewith, to have surrendered his Warrants for cancellation, in each
case, for a redemption price per Warrant equal to the Redemption Amount and, in
each case, without any further action on the part of the Corporation or any
Warrantholder. Within three Business Days of the Corporation having given the
notice contemplated by subsection 3.04(1), the Trustee shall send by ordinary
mail to each Warrantholder, or to such person as such holder may otherwise
specify by written notice to the Trustee prior to such mailing, at the address
of such holder or, if so specified, such person, a cheque or bank draft made
payable to or to the order of such holder or, if so specified, such person, in
an aggregate amount equal to the Redemption Amount for each unexercised Warrant
held by such Warrantholder less applicable withholding taxes, if any. Subject to
the Corporation's obligations pursuant to Section 3.05, the Corporation hereby
authorizes and directs the Trustee, and the Trustee is hereby authorized and
directed, to use the Escrowed Funds to satisfy all such cheques and/or bank
drafts issued in payment of the aggregate Redemption Amount as aforesaid.

(3)      Upon such payment and the cheque or bank draft being satisfied at par
on presentation, all rights under any Warrant in respect of which such payment
has been made will wholly cease and terminate and the Warrant certificate
therefor will be void and of no further force or effect.

(4)      If a Warrantholder requests that a cheque or bank draft referred to
above be made payable to a person other than the registered Warrantholder, the
Warrantholder's signature on his written notice to the Trustee specifying such
other person should be guaranteed by a Canadian chartered bank, by a trust
company or a member firm of The Toronto Stock Exchange.

(5)      Any payment made in accordance with these provisions shall, to the
extent of the sum represented thereby, satisfy and discharge all liability of

bank draft by a person to whom it is so sent as aforesaid, or the loss or
destruction thereof, the Trustee will issue to such person a replacement cheque
or bank draft for like amount upon being furnished with such evidence of
non-receipt, loss or destruction and with such indemnity as the Trustee may
reasonably require. The balance of the funds held by the Trustee, if any, after
any payments referred to above, will be paid to the Corporation not later than
12:00 (noon) (Toronto time) on June 1, 1998.

SECTION 3.05 - CORPORATION TO FUND SHORTFALL

         To the extent that the Escrowed Funds are insufficient to permit the
Trustee to pay the aggregate Redemption Amount as aforesaid, the Corporation
shall provide to the Trustee, by certified cheque or bank draft, sufficient
funds in sufficient time to permit the Trustee to pay and satisfy the aggregate
Redemption Amount as aforesaid.

SECTION 3.06 - TRANSACTION APPROVAL

         For greater certainty, if the Corporation obtains Transaction Approval
on or prior to the Qualification Deadline, the Corporation shall have no further
obligation, nor any right, to redeem the Warrants and the provisions of
subsection 3.04(1) hereof shall be of no further force or effect. In such case,
the Corporation shall have no obligation to give notice of the obtaining of
Transaction Approval to any Warrantholder or to the Trustee.

                                TRIGGERING EVENT


SECTION 4.01 - TRIGGERING EVENT

         If for any reason, other than by reason of an Event of Force Majeure
(in which case the Clearance Date shall be extended by a period of time equal to
the period during which such Event of Force Majeure exists), Transaction
Approval has been obtained but the Clearance Date does not occur by 5:00 p.m.
(local time) on the Qualification Deadline or the Corporation is unable to file
the Final Prospectus with the Securities Commission of any Designated Province
by 5:00 p.m. (local time) on the Qualification Deadline (a "TRIGGERING EVENT"),
the Corporation shall forthwith give notice of that fact to the Trustee and to
each of the Warrantholders resident in the relevant Designated Province(s)
(non-Canadian resident holders of Warrants being deemed to be resident in the
Province of Ontario for this purpose), which notice shall also describe the
change in the exercise rights attaching to the Warrants held by such
Warrantholders as a result of such Triggering Event.

SECTION 4.02 - CHANGE IN EXERCISE RIGHTS

         Upon the occurrence during the Exercise Period of a Triggering Event
with respect to a Designated Province, each Warrant held by a holder resident or
deemed resident in such province shall thereafter entitle the holder, without
further action being required to be taken hereunder, to acquire (subject to
subsection 5.01(2)), at no additional cost, 1.09 Exchangeable Shares or such
other kind and amount of Underlying Shares as is herein provided in accordance
with the

<PAGE>   26
                                     - 21 -


provisions of this Indenture. In such case, but without derogating from the
Corporation's obligation to use its reasonable efforts to obtain from each of
the Securities Commissions in the Designated Provinces, as soon as practicable,
a receipt or similar document for the Final Prospectus, the Exchangeable Shares
issued upon the exercise or deemed exercise of the Warrants will be subject to
restrictions on the resale thereof in accordance with applicable Securities Laws
and U.S. Securities Laws and may bear a legend to such effect.

                              EXERCISE OF WARRANTS


SECTION 5.01 - METHOD OF EXERCISE OF WARRANTS

(1)      The holder of any Warrant may exercise during the Exercise Period the
right thereby conferred on such holder to acquire without further payment
(except as provided in subsection 5.01(2)) the Underlying Shares to which such
Warrant entitles the holder by surrendering such Warrant to the Trustee at any
time during the Exercise Period at its principal stock and bond transfer office
in the City of Toronto (or at such additional place or places as may be decided
by the Corporation from time to time with the approval of the Trustee) with a
duly completed and executed exercise form substantially in the form set out in
the Warrant certificate. A Warrant with the duly completed and executed exercise
form shall be deemed to be surrendered only upon personal delivery thereof to,
or if sent by mail or other means of transmission upon actual receipt thereof
by, the Trustee.

(2)      Any exercise form referred to in subsection 5.01(1) shall be signed by
the Warrantholder. If any of the Underlying Shares issuable upon the exercise of
Warrants by a holder are to be issued to a person or persons other than the
Warrantholder, the signatures set out in the exercise form referred to in
subsection 5.01(1) shall be guaranteed by a Canadian chartered bank, a Canadian
trust company or a member firm of The Toronto Stock Exchange and the
Warrantholder shall pay to the Corporation or the Trustee all applicable
transfer or similar taxes and the Corporation shall not be required to issue or
deliver certificates evidencing Underlying Shares unless or until such
Warrantholder shall have paid to the Corporation or the Trustee on behalf of the
Corporation the amount of such tax or shall have established to the satisfaction
of the Corporation that such tax has been paid or that no such tax is due. The
exercise form attached to the Warrant certificate shall be completed to specify
the person or persons in whose name or names the Underlying Shares to be issued
upon exercise are to be registered, such person's or persons' address or
addresses and the number of Underlying Shares to be issued to each person if
more than one is so specified.

SECTION 5.02 - AUTOMATIC EXERCISE

(1)      If at the Time of Expiry the holder of a Warrant certificate has not
exercised his right to acquire Underlying Shares during the Exercise Period in
accordance with the provisions of Section 5.01, the Warrants held by such
Warrantholder shall be deemed to have been exercised by such Warrantholder,
without any further action on the part of such Warrantholder, immediately prior
to the expiry of the Exercise Period.

(2)      If a Clearance Date occurs during the Exercise Period, the Corporation
shall forthwith give notice of such occurrence, together with copies of the
receipts for the Final Prospectus, to the Trustee.

(3)      As soon as practicable following the automatic exercise of the Warrants
pursuant to this Section 5.02, the Trustee shall notify each of the holders of
such Warrants as have been automatically exercised to the effect that such
Warrants have been automatically exercised and that the holders thereof have
acquired the Underlying Shares and shall be entered in the relevant register(s)
of holders of Underlying Shares, in each case, effective as at the Expiry Time,
and shall receive certificates for the Underlying Shares to which they have
become entitled.

SECTION 5.03 - EFFECT OF EXERCISE OF WARRANTS

(1)      Upon compliance by the Warrantholder with the provisions of Section
5.01 or the automatic exercise of the Warrants pursuant to Section 5.02, the
Underlying Shares issuable upon the exercise of the Warrants shall be deemed to
have been issued and the person to whom such Underlying Shares are to be issued
shall be deemed to have become the holder of record of such Underlying Shares on
the Exercise Date unless the transfer registers of the Corporation for the
Exchangeable Shares shall be closed on such date, in which case the Underlying
Shares subscribed for shall be deemed to have been issued and such person shall
be deemed to have become the holder of record of such Underlying Shares on the
date on which such transfer registers are reopened.

(2)      Forthwith following the due exercise by a Warrantholder of Warrants in
accordance with Section 5.01 or the automatic exercise of the Warrants pursuant
to Section 5.02, the Trustee shall deliver to the Corporation a notice setting
out the particulars of the Warrants exercised, the person in whose name the
Underlying Shares are to be issued and the address of such person.

(3)      Within three Business Days of receipt of the notice referred to in
subsection 5.03(2), the Corporation shall cause to be mailed to the person in
whose name the Underlying Shares issuable upon the exercise of the Warrants are
to be issued, as specified in the exercise form completed on the Warrant, at the
address specified therein, or, if so specified in such exercise form, cause to
be delivered to such person at the office of the Trustee where such Warrant was
surrendered, or in the

<PAGE>   28
                                     - 23 -


event of the automatic exercise of the Warrants pursuant to Section 5.02, to the
applicable Warrantholder at his address specified in the register for the
Warrants, a certificate or certificates for the Underlying Shares to which the
Warrantholder is entitled.

(4)      If at the time of any exercise of the Warrants there remain trading
restrictions on the Underlying Shares pursuant to applicable Securities Laws,
the Corporation may, upon the advice of counsel, endorse any certificates
representing the Underlying Shares to such effect.

SECTION 5.04 - CANCELLATION OF WARRANT CERTIFICATES

         All Warrant certificates surrendered to the Trustee pursuant to Section
2.06, 2.11 or 5.01 shall be cancelled by the Trustee. All Warrant certificates
deemed to have been exercised pursuant to Section 5.02 shall be deemed to have
been cancelled by the Trustee. All Warrants represented by Warrant certificates
that have been cancelled or have been deemed to have been cancelled pursuant to
this Section 5.04 shall be without further force or effect whatsoever.

SECTION 5.05 - NOTICE OF EXTENSION OF QUALIFICATION DEADLINE

         If the Corporation and the Underwriters extend the Qualification
Deadline, the Corporation shall forthwith give notice in writing thereof to the
Trustee and the Warrantholders.

SECTION 5.06 - LEGEND ON EXCHANGEABLE SHARES

         All certificates representing Exchangeable Shares shall have typed
thereon the following legend:

         "The Exchangeable Shares issuable upon exercise of the Special Warrants

         Learning Company, Inc. (the "Common Stock") issuable upon exchange of
         the Exchangeable Shares have not been registered under the Securities
         Act of 1933, as amended, of the United States of America (the "U.S.
         Securities Act"); the Exchangeable Shares and the Common Stock may not
         be offered, sold or otherwise transferred within the United States or
         to, or for the account or benefit of, any U.S. person (as such terms
         are defined in Regulation S promulgated under the U.S. Securities Act)
         unless such offer, sale or transfer is covered by or made pursuant to
         an effective registration statement under the U.S. Securities Act or
         pursuant to an exemption from registration under the U.S. Securities
         Act, nor may any Exchangeable Share be offered, sold or otherwise
         transferred

         within the United States or to, or for the account or benefit of, any
         U.S. person unless the issuance of the Common Stock is registered under
         an effective registration statement under the U.S. Securities Act or an
         exemption from registration under the U.S. Securities Act is available
         for the exchange of the Exchangeable Shares. Any holder that surrenders
         this certificate in exchange for Common Stock prior to effectiveness of
         a registration statement filed under the U.S. Securities Act covering
         such exchange must certify that the holder is not a U.S. person."

Corporation or may itself perform any of the said covenants capable of being
performed by it but shall be under no obligation to perform said covenants or to
notify the Warrantholders of such performance by it. All reasonable sums

acquired Exchangeable Shares thereunder immediately prior to the effective date
or record date of the dividend or distribution. For cash dividends, this
entitlement shall be satisfied by the payment of such amounts by the Corporation
to the holders of the Warrants. For stock dividends or distributions in respect

the matter. It shall not be necessary for any such notice to set out the terms
of any resolution to be proposed or any of the provisions of this Article Eight.
The notice convening any such meeting may be signed by an appropriate officer of
the Trustee or of the Corporation or the person designated by such
Warrantholders, as the case may be.

SECTION 8.03 - CHAIR

         The Trustee may nominate in writing an individual to be Chair of the
meeting and if no individual is so nominated, or if the individual so nominated
is not present within 15 minutes after the time fixed for the holding of the
meeting, the Warrantholders present in person or by proxy shall appoint an
individual present to be Chair.

SECTION 8.04 - QUORUM

         Subject to the provisions of Section 8.11, at any meeting of the
Warrantholders a quorum shall consist of Warrantholders present in person or
represented by proxy and holding at least 10% of the aggregate number of
Warrants then unexercised and outstanding, provided that at least two persons
entitled to vote thereat are personally present. If a quorum of the
Warrantholders shall not be present within one half-hour from the time fixed for
holding any meeting, the meeting, if summoned by the Warrantholders or on a
Warrantholders' Request, shall be dissolved; but in any other case the meeting

or represented by proxy shall form a quorum and may transact the business for
which the meeting was originally convened notwithstanding that they may not hold
at least 10% of the aggregate number of Warrants then unexercised and
outstanding. No business shall be transacted at any meeting unless a quorum is
present at the commencement of business.

SECTION 8.05 - POWER TO ADJOURN

         The Chair of any meeting at which a quorum of the Warrantholders is
present, with the consent of the meeting, may adjourn any such meeting and no
notice of such adjournment need be given except such notice, if any, as the
meeting may prescribe.

SECTION 8.06 - SHOW OF HANDS

         Every question submitted to a meeting shall be decided in the first
place by a majority of the votes given on a show of hands except that votes on
an extraordinary resolution shall be given in the manner hereinafter provided.
At any such meeting, unless a poll is duly demanded as herein provided, a
declaration by the Chair that a resolution has been carried or carried
unanimously or by a particular majority or lost or not carried by a particular
majority shall be conclusive evidence of the fact.

SECTION 8.07 - POLL AND VOTING

         On every extraordinary resolution, and when demanded by the Chair or by
one or more of the Warrantholders acting in person or by proxy on any other
question submitted to a meeting and after a vote by show of hands, a poll shall
be taken in such manner as the Chair shall direct. Questions other than those
required to be determined by extraordinary resolution shall be decided by a
majority of the votes cast on a poll. On a show of hands, every person who is
present and entitled to vote, whether as a Warrantholder or as proxy for one or
more absent Warrantholders, or both, shall have one vote. On a poll, each
Warrantholder present in person or represented by a proxy duly appointed by
instrument in writing shall be entitled to one vote in respect of each Warrant
that he (or the Warrantholder appointing him as proxy) holds. A proxyholder need
not be a Warrantholder. The Chair of any meeting shall be entitled to vote, both
on a show of hands and on a poll, in respect of any Warrants held or represented
by him.

         meeting;

    (b)  for the deposit of instruments appointing proxies at some approved
         place other than the place at which the meeting is to be held and
         enabling particulars of such instruments appointing proxies to be
         mailed or telecopied before the meeting to the Corporation or to the
         Trustee at the place where the meeting is to be held and for the voting
         of proxies so deposited as though the instruments themselves were
         produced at the meeting;

    (c)  for the form of the instrument of proxy; and

    (d)  generally for the calling of meetings of Warrantholders and the conduct
         of business thereat.

SECTION 8.11 - MEANING OF EXTRAORDINARY RESOLUTION

(1)      The expression "EXTRAORDINARY RESOLUTION" when used in this Indenture
means, subject to this Section 8.11 and Section 8.14, a resolution proposed at a
meeting of Warrantholders duly convened for that purpose and held in accordance
with the provisions of this Article Seven at which there are present in person
or represented by proxy Warrantholders holding at least 25% of the aggregate
number of then outstanding unexercised Warrants and passed by the affirmative
votes of Warrantholders holding not less than 66 2/3% of the aggregate number of
the then outstanding unexercised Warrants represented at the meeting and voted
on the poll upon such resolution.

(2)      If, at any meeting called for the purpose of passing an extraordinary
resolution, Warrantholders holding at least 25% of the aggregate number of then
outstanding unexercised Warrants are not present in person or by proxy within
one half-hour after the time appointed for the meeting, then the meeting, if
convened by Warrantholders or on a Warrantholders' Request, shall be dissolved;
but in any other case it shall stand adjourned to such day, being not less than
four or more than 10 Business Days later, and to such place and time as may be
appointed by the Chair. Not less than three Business Days' prior notice shall be
given of the time and place of such adjourned meeting in the manner provided in
Article Eleven. Such notice shall state that at the adjourned meeting the
Warrantholders present in person or represented by proxy shall form a quorum but
it shall not be necessary to set forth the purposes for which the meeting was
originally called or any other particulars. At the adjourned meeting the
Warrantholders present in person or represented by proxy shall form a quorum and
may transact the business for which the meeting was originally convened and a
resolution proposed at such adjourned meeting and passed by the requisite vote
as provided in subsection 8.11(1) shall be an extraordinary resolution within
the meaning of this Indenture notwithstanding that Warrantholders holding at
least 25% of the aggregate number of then outstanding unexercised Warrants are
not present in person or represented by proxy at such adjourned meeting.

(3)      Votes on an extraordinary resolution shall always be given on a poll
and no demand for a poll on an extraordinary resolution shall be necessary.

any combination of the powers in this Indenture stated to be exercisable by the

combination of powers from time to time shall not be deemed to

<PAGE>   38
                                     - 33 -


exhaust the right of the Warrantholders to exercise such powers or combination
of powers then or thereafter from time to time.

SECTION 8.13 - MINUTES

         Minutes of all resolutions and proceedings at every meeting of
Warrantholders shall be made and duly entered in books to be from time to time
provided for that purpose by the Trustee at the reasonable expense of the
Corporation and any such minutes, if signed by the Chair of the meeting at which
such resolutions were passed or proceedings held or by the Chair of the next
succeeding meeting of the Warrantholders, shall be prima facie evidence of the
matters therein stated and, until the contrary is proved, every such meeting in
respect of the proceedings of which minutes shall have been made shall be deemed
to have been duly convened and held and all resolutions passed thereat or
proceedings taken shall be deemed to have been duly passed and taken.

SECTION 8.14 - INSTRUMENTS IN WRITING

         All actions that may be taken and all powers that may be exercised by
the Warrantholders at a meeting held as provided in this Article Seven also may

aggregate number of then outstanding unexercised Warrants by an instrument in

shall be binding upon all the Warrantholders, whether signatories thereto or
not, and each and every Warrantholder and the Trustee (subject to the provisions
for indemnity herein contained) shall be bound to give effect accordingly to
every such resolution and instrument in writing. In the case of an instrument in
writing, the Trustee shall give notice in the manner contemplated in Section
11.01 of the effect of the instrument in writing to all Warrantholders and the
Corporation as soon as is reasonably practicable.

SECTION 8.16 - HOLDINGS BY THE CORPORATION OR SUBSIDIARIES OF THE CORPORATION
               DISREGARDED

         In determining whether Warrantholders holding the required number of
outstanding Warrants are present at a meeting of Warrantholders for the purpose
of determining a quorum or the number of holders who have concurred in any

this Indenture, they shall execute and deliver by their proper officers,
indentures or instruments supplemental hereto, which thereafter shall form part
hereof, for any one or more or all of the following purposes:

    (a)  setting forth adjustments in the application of Article Two;

    (b)  adding to the provisions hereof such additional covenants and
         enforcement provisions as in the opinion of counsel are necessary or

         of the Warrantholders as a group;

    (c)  giving effect to any extraordinary resolution passed as provided in
         Article Eight;

    (d)  making such provisions not inconsistent with this Indenture as may be

         of the Warrantholders as a group;

<PAGE>   40
                                     - 35 -


    (e)  adding to or amending the provisions hereof in respect of the transfer
         of Warrants, making provision for the exchange of Warrants and making
         any modification in the forms of the Warrant certificates that does not
         affect the substance thereof;

    (f)  making any additions to, deletions from or alterations to the
         provisions of this Indenture which, in the opinion of the Trustee
         relying on the advice of counsel, do not materially and adversely
         affect the interests of the Warrantholders and are necessary or
         advisable in order to incorporate, reflect or comply with any
         Applicable Legislation; and

    (g)  for any other purpose not inconsistent with the terms of this
         Indenture, including the correction or rectification of any
         ambiguities, defective or inconsistent provisions, errors or omissions
         herein, provided that, in the opinion of the Trustee relying on the
         opinion of counsel, the rights of the Trustee and of the Warrantholders
         as a group are not prejudiced thereby.

SECTION 9.02 - SUCCESSOR CORPORATIONS

         In the case of the consolidation, amalgamation, arrangement, merger or
transfer of the undertaking or assets of the Corporation as an entirety or
substantially as an entirety to another person (a "SUCCESSOR"), forthwith
following the occurrence of such event the successor resulting from such
consolidation, amalgamation, arrangement, merger or transfer (if not the
Corporation) shall expressly assume, by supplemental indenture satisfactory in
form to the Trustee relying on the advice of counsel and executed and delivered
to the Trustee, the due and punctual performance and observance of each and
every covenant and condition of this Indenture to be performed and observed by
the Corporation and, in any event, shall be bound by the provisions hereof and
all obligations for the due and punctual performance and observance of each and
every covenant and obligation contained in this Indenture to be performed by the
Corporation.


                                  ARTICLE TEN

                             CONCERNING THE TRUSTEE


SECTION 10.01 - TRUST INDENTURE LEGISLATION

(1)      In this Article, the term "APPLICABLE LEGISLATION" means the
provisions, if any, of the Business Corporations Act (Ontario) and any other
statute of Ontario or Canada and of regulations under any such named or other
statute relating to trust indentures and/or to the rights,



<PAGE>   41
                                     - 36 -


duties and obligations of trustees and of corporations under trust indentures to
the extent that such provisions are at the time in force and applicable to this
Indenture.

(2)      If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with a mandatory requirement of Applicable Legislation,
such mandatory requirement shall prevail.

(3)      The Corporation and the Trustee agree that at all times in relation to
this Indenture and any action to be taken hereunder each will observe and comply
with and be entitled to the benefit of Applicable Legislation.

SECTION 10.02 - RIGHTS AND DUTIES OF TRUSTEE

(1)      In the exercise of the rights and duties prescribed or conferred by the
terms of this Indenture, the Trustee shall act honestly and in good faith with a
view to the best interests of the Warrantholders and shall exercise the degree
of care, diligence and skill that a reasonably prudent trustee would exercise in
comparable circumstances. No provision of this Indenture shall be construed to
relieve the Trustee from, or require any other person to indemnify the Trustee
against, liability for its own gross negligence, wilful misconduct or bad faith.

(2)      Subject only to subsection 10.02(1), the Trustee shall not be bound to
do or take any act, action or proceeding for the enforcement of any of the
obligations of the Corporation under this Indenture unless and until it shall
have received a Warrantholders' Request specifying the act, action or proceeding
that the Trustee is requested to take. The obligation of the Trustee to commence
or continue any act, action or proceeding for the purpose of enforcing any
rights of the Trustee or the Warrantholders hereunder shall be conditional upon
the Warrantholders furnishing, when required by notice in writing by the
Trustee, sufficient funds to commence or continue such act, action or proceeding
and an indemnity reasonably satisfactory to the Trustee to protect and hold
harmless the Trustee against the costs, charges, expenses and liabilities to be
incurred thereby and any loss and damage it may suffer by reason thereof. None
of the provisions contained in this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties or in the exercise of any of its rights or
powers unless indemnified as aforesaid.

(3)      The Trustee, before commencing or at any time during the continuance of
any such act, action or proceeding, may require the Warrantholders at whose
instance it is acting to deposit with the Trustee the Warrants held by them, for
which Warrants the Trustee shall issue receipts.

(4)      Every provision of this Indenture that by its terms relieves the
Trustee of liability or entitles it to rely upon any evidence submitted to it is
subject to the provisions of Applicable Legislation, of this Section 10.02 and
of Section 10.03.

                                     - 37 -


SECTION 10.03 - EVIDENCE, EXPERTS AND ADVISERS

(1)      In addition to the reports, certificates, opinions and other evidence
required by this Indenture, the Corporation shall furnish to the Trustee such
additional evidence of compliance with any provision hereof in such form as may
be prescribed by Applicable Legislation or as the Trustee may reasonably require
by written notice to the Corporation.

(2)      In the exercise of its rights and duties hereunder, the Trustee, if it
is acting in good faith, may rely as to the truth of the statements and the
accuracy of the opinions expressed therein, upon statutory declarations,
opinions, reports, written requests, consents or orders of the Corporation,
certificates of the Corporation or other evidence furnished to the Trustee
provided that such evidence complies with Applicable Legislation and the Trustee
examines the same and determines that such evidence complies with the applicable
requirements of this Indenture.

(3)      Whenever Applicable Legislation requires that evidence referred to in
subsection 10.03(1) be in the form of a statutory declaration, the Trustee may
accept such statutory declaration in lieu of a certificate of the Corporation
required by any provision hereof. Any such statutory declaration may be made by
one or more of the chairman, chief executive officer, president or any
vice-president of the Corporation.

(4)      Proof of the execution of an instrument in writing, including a
Warrantholders' Request, by any Warrantholder may be made by the certificate of
a notary public, or other officer with similar powers, that the person signing
such instrument acknowledged to him the execution thereof or by an affidavit of
a witness to such execution or in any other manner that the Trustee may consider
adequate.

(5)      The Trustee may employ or retain such counsel, accountants or other
experts or advisers as it may reasonably require for the purpose of determining
and discharging its duties hereunder, may act on and rely upon, and shall be
protected in acting and relying in good faith upon, the advice or opinions so
obtained and may pay reasonable remuneration for all services so performed by
any of them (any such remuneration paid by the Trustee to be repaid by the
Corporation to the Trustee in accordance with Section 6.03), without taxation of
costs of any counsel, and shall not be responsible for any misconduct on the
part of any of them.

SECTION 10.04 - DOCUMENTS, MONEY, ETC. HELD BY TRUSTEE

(1)      Any securities, documents of title or other instruments that may at any
time be held by the Trustee subject to the trusts hereof may be placed in the
deposit vaults of the Trustee or of any

<PAGE>   43
                                     - 38 -


Canadian chartered bank or trust company or deposited for safekeeping with any
such bank or trust company.

(2)      Unless otherwise expressly provided herein, any monies so held pending
the application or withdrawal thereof under any provision of this Indenture
shall be held in the name of the Trustee in a segregated trust account with any
Canadian chartered bank or financial institution (which may be the Trustee or
any affiliate or related party), at the rate of interest then current on similar
deposits or, on the direction of the Corporation, may be invested in Permitted
Investments. Any such direction by the Corporation to the Trustee as to the
investment of the funds shall be in writing and shall be provided to the Trustee
no later than 9:00 a.m. on the day on which the investment is to be made. Any
such direction received by the Trustee after 9:00 a.m. or received on a
non-Business Day, shall be deemed to have been given prior to 9:00 a.m. the next
Business Day.

SECTION 10.05 - ACTIONS BY TRUSTEE TO PROTECT INTERESTS

         The Trustee shall have the power to institute and to maintain such
actions and proceedings as it may consider necessary or expedient to preserve,
protect or enforce its interests and the interests of the Warrantholders.

SECTION 10.06 - TRUSTEE NOT REQUIRED TO GIVE SECURITY

         The Trustee shall not be required to give any bond or security in
respect of the execution of the trusts and powers of this Indenture or
otherwise.

SECTION 10.07 - PROTECTION OF TRUSTEE

         By way of supplement to the provisions of any law for the time being
relating to trustees, it is expressly declared and agreed as follows:

(1)      The Trustee shall not be liable for or by reason of any statements of
fact or recitals in this Indenture or in the Warrants (except the representation
contained in Section 10.09 or in the certificate of the Trustee on the Warrants)
or be required to verify the same.

(2)      Nothing herein contained shall impose any obligation on the Trustee to
see to or to require evidence of the registration or filing (or renewal thereof)
of this Indenture or any instrument ancillary or supplemental hereto.

(3)      The Trustee shall not be bound to give notice to any person of the
execution hereof.

<PAGE>   44
                                     - 39 -


(4)      The Trustee shall not incur any liability or responsibility whatsoever
or be in any way responsible for the consequence of any breach on the part of
the Corporation of any of the covenants herein contained or of any acts of any
directors, officers, employees, agents or servants of the Corporation.

SECTION 10.08 - REPLACEMENT OF TRUSTEE

(1)      The Trustee may resign its trust and be discharged from all further
duties and liabilities hereunder by giving to the Corporation not less than 45
days' prior notice in writing or such shorter prior notice as the Corporation
may accept as sufficient. The Warrantholders by extraordinary resolution shall
have the power at any time to remove the existing Trustee and to appoint a new
trustee. In the event of the Trustee resigning or being removed as aforesaid or
being dissolved, becoming bankrupt, going into liquidation or otherwise becoming
incapable of acting hereunder, the Corporation shall forthwith appoint a new
trustee unless a new trustee has already been appointed by the Warrantholders.
Failing such appointment by the Corporation, within 10 days the retiring Trustee
or any Warrantholder may apply to a justice of the Ontario Court (General
Division) at the Corporation's expense, on such notice as such justice may
direct, for the appointment of a new trustee. Any new trustee so appointed by
the Corporation or by the Court shall be subject to removal as aforesaid by the
Warrantholders. Any new trustee appointed under any provision of this Section
10.08 shall be a corporation authorized to carry on the business of a trust
company in the Province of Ontario and, if required by Applicable Legislation of
any other province, in such other province. On any such appointment, the new
trustee shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named herein as Trustee without
any further assurance, conveyance, act or deed. In addition, there shall be
immediately executed, at the expense of the Corporation, all such conveyances or
other instruments as may be necessary or advisable, in the opinion of counsel,
for the purpose of assuring the same to the new trustee, provided that any
resignation or removal of the Trustee and appointment of a successor trustee
shall not become effective until the successor trustee shall have executed an
appropriate instrument accepting such appointment and, at the request of the
Corporation, the predecessor Trustee, upon payment of its outstanding
remuneration and expenses, shall execute and deliver to the successor trustee an
appropriate instrument transferring to such successor trustee all rights and
powers of the Trustee hereunder.

(2)      Upon the appointment of a successor trustee, the Corporation shall
promptly notify the Warrantholders thereof.

(3)      Any corporation into or with which the Trustee may be merged or
consolidated or amalgamated or any corporation succeeding to the trust business
of the Trustee shall be the successor to the Trustee hereunder without any
further act on its part or of any of the parties hereto, provided that such
corporation would be eligible for appointment as a new trustee under 
subsection 10.08(1).

<PAGE>   45
                                     - 40 -


(4)      Any Warrants certified but not delivered by a predecessor trustee may
be certified by the successor trustee in the name of the predecessor or
successor trustee.

SECTION 10.09 - CONFLICT OF INTEREST

(1)      The Trustee represents to the Corporation that at the time of execution
and delivery hereof no material conflict of interest exists in the Trustee's
role as a fiduciary hereunder and agrees that in the event of a material
conflict of interest arising hereafter it will, within 90 days after
ascertaining that it has such a material conflict of interest, either eliminate
the same or resign its trust hereunder to a successor trustee approved by the
Corporation. If any such material conflict of interest exists or hereafter shall
exist, the validity and enforceability of this Indenture and the Warrants shall
not be affected in any manner whatsoever by reason thereof.

(2)      Subject to subsection 10.09(1), the Trustee in its personal or any
other capacity may buy, lend upon and deal in securities of the Corporation and
generally may contract and enter into financial transactions with the
Corporation or any subsidiary of the Corporation without being liable to account
for any profit made thereby.

SECTION 10.10 - ACCEPTANCE OF TRUSTS

         The Trustee hereby accepts the trusts in this Indenture declared and
provided for and agrees to perform the same upon the terms and conditions herein
set forth, and to hold all rights, interests and benefits contained herein for
and on behalf of those persons who become Warrantholders from time to time.

SECTION 10.11 - TRUSTEE NOT TO BE APPOINTED RECEIVER

         The Trustee and any person related to the Trustee shall not be
appointed a receiver or receiver and manager or liquidator of all or any part of
the assets or undertaking of the Corporation.

SECTION 10.12 - INDEMNITY OF TRUSTEE

         The Corporation hereby indemnifies and holds harmless the Trustee and
its officers, directors, employees and agents from and against all reasonable
costs, liabilities, expenses and disbursements (including reasonable legal fees
and disbursements) that it might incur or to which it might have become subject
in any action, suit or other similar legal proceeding that might be instituted
against the Trustee arising from or out of any act, omission or error of the
Trustee arising pursuant to this Indenture, provided that the Trustee acted in
accordance with the standards set forth

<PAGE>   46
                                     - 41 -


in Section 9.02 and that any such act, omission or error did not constitute
negligence, wilful misconduct or bad faith on the part of the Trustee. This
Section 10.12 shall survive the resignation or removal of the Trustee or the
termination of this Indenture.

         receipt and, if it is not, on the next following Business Day) and if
         telecopied other than during business hours, on the next following
         Business Day; and

    (c)  if sent by letter or courier delivery in accordance with the provisions
         of clause 11.01(1)(c), on the date the letter is actually received by
         the addressee.

(3)      For greater certainty, a letter delivered by courier where such courier
obtains a written acknowledgement of receipt from the party receiving the letter
shall be considered a delivery in person in accordance with clause 11.01(1)(a)
rather than the sending of a letter in accordance with clause 11.01(1)(c).

(4)      Any party may from time to time by notice in writing delivered in
accordance with the provisions of this Article Eleven change its address for
purposes hereof.

                                      - 2 -


for the (final) prospectus (the "Final Prospectus") of the Corporation
qualifying the exchangeable non-voting shares (the "Exchangeable Shares") of the
Corporation to be issued upon the exercise of the Warrants, to acquire in
accordance with the provisions of the Warrant Indenture (as defined below) one
Exchangeable Share (or 1.09 Exchangeable Shares to be issued by the Corporation
in the circumstances described below), subject to adjustment, for each Warrant
represented hereby without payment of any consideration in addition to the issue
price of such Warrant by surrendering to CIBC Mellon Trust Company (the
"Trustee") at its principal office in the City of Toronto this Warrant
certificate together with an executed exercise form in the form of the attached
Exercise Form or any other written notice in a form satisfactory to the Trustee,
in either case duly completed and executed PROVIDED THAT UNLESS THE HOLDER HAS
SURRENDERED THE WARRANTS REPRESENTED HEREBY FOR EXERCISE PURSUANT TO THE
PROVISIONS HEREOF AND OF THE WARRANT INDENTURE DURING THE EXERCISE PERIOD, THE
WARRANTS REPRESENTED HEREBY SHALL BE DEEMED TO HAVE BEEN EXERCISED BY THE HOLDER
AT THE EXPIRY TIME WITHOUT FURTHER NOTICE TO OR ACTION ON THE PART OF THE
HOLDER. For the purposes of this Warrant certificate, "Underwriters" means,
collectively, Griffiths McBurney & Partners and First Marathon Securities
Limited.

         Upon the exercise or deemed exercise of the Warrants evidenced hereby,
the Corporation shall cause to be issued to the person(s) in whose name(s) the
Exchangeable Shares so subscribed for are to be issued (provided that, if the
Exchangeable Shares are to be issued to a person other than a holder of this
Warrant certificate, the holder's signature on the Exercise Form herein shall be
guaranteed by a Canadian chartered bank, by a Canadian trust company or by a
member firm of The Toronto Stock Exchange) the number of Exchangeable Shares to
be issued to such person(s) and such person(s) shall become a holder in respect
of Exchangeable Shares with effect from the date of such exercise and upon due
surrender of this Warrant certificate. The Corporation will cause a
certificate(s) representing such Exchangeable Shares to be made available for
pick-up by such person(s) at 393 University Avenue, 5th Floor, Toronto, Ontario
M5G 2M7, or mailed to such person(s) at the address(es) specified in such
Exercise Form, within two Business Days after receipt of notice from the Trustee
of the exercise of this Warrant.

         The net proceeds of sale of the Warrants will be deposited on the date
hereof in escrow with the Trustee to be held and invested by the Trustee in
accordance with the provisions of the Warrant Indenture. In the event that the
Corporation fails to obtain Transaction Approval on or prior to March 6, 1998 or
such later date as may be agreed upon in writing by the Corporation and the
Underwriters (the "Qualification Deadline") the Corporation shall redeem each
Warrant for an amount equal to the purchase price paid by the Warrantholder for
the Warrant, together with interest thereon as provided in the Warrant
Indenture. For the purposes of this Warrant certificate, "Transaction Approval"
means Shareholder Approval together with all such other consents and approvals
necessary to ensure that the rights and benefits of the holders of Underlying
Shares are substantially equivalent to the rights and benefits of the holders of
the existing Exchangeable Shares; provided that, for greater certainty
Transaction Approval shall not include the filing of, or the 

<PAGE>   52
                                     - 3 -


obtaining of a receipt for, the Final Prospectus. For the purposes of this
Warrant certificate, "Shareholder Approval" means the approval of the holders of
the Exchangeable Shares to, among other things, the issue by the Corporation,
from time to time, of Exchangeable Shares in addition to those shares
outstanding on the record date for the Shareholder Meeting, such approval to be
given by resolution passed by not less than two-thirds of the votes cast on such
resolution at the Shareholder Meeting, as required by and in accordance with the
rights, privileges, restrictions and conditions attaching to the Exchangeable
Shares. For the purposes of this Warrant certificate, "Shareholder Meeting"
means the special meeting or meeting (including any adjournments thereof) of the
holders of the Exchangeable Shares to be called and held in accordance with the
articles and by-laws of the Corporation for the purpose of obtaining Shareholder
Approval.

         In the event that the Corporation satisfies the Transaction Support
Condition or obtains Shareholder Approval prior to the Qualification Deadline,
the Trustee shall, upon receipt of written notice and supporting documents, in
prescribed form, release the Escrowed Funds to the Corporation for the purpose
of completing the purchase of Creative Wonders L.L.C. If the Escrowed Funds are
not released to the Corporation as aforesaid, the Escrowed Funds will be
released to the Corporation on the first to occur of (a) the last Clearance Date
to occur in British Columbia, Ontario and Quebec and (b) the Qualification
Deadline, provided only that the Corporation has obtained Transaction Approval
by such date. For the purpose of this Warrant certificate, "Transaction Support
Condition" means the obtaining by the Corporation of irrevocable proxies
executed by holders of not less than 50.1% of the Exchangeable Shares
outstanding on the record date for, and eligible to vote at, the Shareholder
Meeting, indicating that such shareholders will vote such shares at the
Shareholder Meeting in favour of, among other things, the issue by the
Corporation, from time to time, of Exchangeable Shares in addition to those
shares outstanding on the record date for the Shareholder Meeting. For the
purpose of this Warrant certificate, "escrowed funds" means the net proceeds of
sale of the Warrants deposited in escrow with the Trustee, and all proceeds of
investment and reinvestment thereof from time to time.

         If, notwithstanding Transaction Approval having been obtained, the
Clearance Date does not occur by 5:00 p.m. (local time) on the Qualification
Deadline, or for any reason the Corporation is unable to file the Final
Prospectus with the securities regulatory authority of the holder's province
(which may only be one of the Provinces of British Columbia, Ontario and Quebec
and will, in the case of non-Canadian resident holders of Warrants, be deemed to
be the Province of Ontario) by 5:00 p.m. (local time) on the Qualification
Deadline, each Warrant represented hereby shall thereafter entitle the holder
upon the exercise or deemed exercise thereof, without further action being
required to be taken hereunder or under the Warrant Indenture, to acquire 1.09
Exchangeable Shares (subject to adjustment) at no additional cost provided that
no fractional Exchangeable Shares will be issued but a cash payment will be made
in lieu thereof. IN SUCH CASE, BUT WITHOUT DEROGATING FROM THE CORPORATION'S
OBLIGATION TO USE ITS REASONABLE EFFORTS TO OBTAIN FROM EACH OF THE SECURITIES

THE EXCHANGEABLE SHARES ISSUED UPON THE EXERCISE OR DEEMED EXERCISE OF THE
WARRANTS WILL BE SUBJECT TO RESTRICTIONS ON THE RESALE THEREOF IN ACCORDANCE
WITH APPLICABLE SECURITIES LAWS OF CANADA AND THE UNITED STATES OF AMERICA AND
MAY BEAR A LEGEND TO SUCH EFFECT.

ALL OF WHICH THE HOLDER OF THIS WARRANT CERTIFICATE BY ACCEPTANCE HEREOF

convertible into Exchangeable Shares or of other securities or assets of the
Corporation, certain offerings of rights, warrants or options and certain
capital reorganizations and for payment of an amount to compensate for dividends
paid on Exchangeable Shares.

         If, immediately prior to the expiry of the Exercise Period, the
Warrants represented by this Warrant certificate have not been exercised, the
Warrants represented hereby shall be deemed to have been exercised and
surrendered by the holder immediately after that time without any further action
on the part of the holder.

except as herein and in the Warrant Indenture expressly provided.

         The transfer of the Warrants evidenced hereby is restricted by
applicable securities laws of Canada and the United States of America. In
addition, no Warrant may be transferred to a person resident in any Province of

legends that will appear on the certificates for the Exchangeable Shares.
