      material respect, then, at the request of the Lender, the Borrower shall
      promptly appoint a consultant from a nationally recognized accounting firm
      acceptable to the Lender at the Borrower's expense. The consultant will be
      given the full and complete cooperation of the Borrower including
      unrestricted access to the property, assets, documents and books and
      records of, or related to, the Borrower's and the Restricted Subsidiaries'
      respective businesses. The Lender may, on the basis of the consultant's
      report, adjust the Applicable Margins in accordance with the
      recommendations set forth in the report.

      adjusted in the same manner as it is for purposes of the Applicable
      Margin.

SECTION 2.9   PAYMENTS UNDER THIS AGREEMENT.

(1)   Unless otherwise expressly provided in this Agreement, the Borrower shall
      (i) make any payment required to be made by it to the Lender by depositing
      the amount of the payment to the relevant Borrower's Account not later
      than 10:00 a.m. (Toronto time) on the date the payment is due, and (ii)
      provide to the Lender, upon the number of Business Days' notice to the
      Lender specified in Schedule 4.1(2) a notice of repayment which shall be
      irrevocable and binding on the Borrower and shall specify (x) the date of
      repayment, and (y) the Type and amount of Accommodation to be repaid. The
      Borrower shall make each such payment (iii) in Canadian Dollars, if the
      Accommodation was originally made in or has been converted to Canadian
      Dollars, and (iv) in U.S. Dollars, if the Accommodation was originally
      made in or has been converted to U.S. Dollars.

(2)   Unless otherwise expressly provided in this Agreement, the Lender shall
      make Accommodations and other payments to the Borrower under this
      Agreement by crediting the relevant Borrower's Account (or causing the
      Borrower's Account to be credited) with the amount of the payment not
      later than 1:00 p.m. (Toronto time) on the date the payment is to be made.

(3)   The Borrower authorizes the Lender, if and to the extent payment owed to
      the Lender by the Borrower is not made when due, to charge from time to
      time any due amount against any or all of the Borrower's accounts with the
      Lender.

SECTION 2.10  APPLICATION OF PAYMENTS AND PREPAYMENTS.

      All amounts received by the Lender from or on behalf of the Borrower and
not previously applied pursuant to this Agreement shall be applied by the Lender
as follows (i) first, in reduction of the Borrower's obligation to pay any
unpaid interest and any Fees which are due and owing, (ii) second, in reduction
of the Borrower's obligation to pay any claims or losses referred to in Section
11.6, (iii) third, in reduction of the Borrower's obligation to pay any amounts

other unpaid

<Page>

                                       26


Accommodations Outstanding which are due and owing, (v) fifth, in reduction of
any other obligation of the Borrower under this Agreement and the other Loan
Documents, and (vi) sixth, to the Borrower or such other Persons as may lawfully
be entitled to or directed to receive the remainder.

SECTION 2.11  COMPUTATIONS OF INTEREST AND FEES.

(1)   All computations of interest shall be made by the Lender taking into
      account the actual number of days occurring in the period for which such
      interest is payable and (i) if based on the Canadian Prime Rate or the
      Base Rate (Canada), on the basis of a year of 365 days, or (ii) if based
      on the Eurodollar Rate, on the basis of a year of 360 days.

(2)   All computations of Fees shall be made by the Lender on the basis of a
      year of 365 days taking into account the actual number of days (including
      the first day but excluding the last day) occurring in the period for
      which the fees are payable.

(3)   For purposes of the INTEREST ACT (Canada), (i) whenever any interest or
      Fee under this Agreement is calculated using a rate based on a year of 360
      days or 365 days, as the case may be, the rate determined pursuant to such
      calculation, when expressed as an annual rate, is equivalent to (x) the
      applicable rate based on a year of 360 days or 365 days, as the case may
      be, (y) multiplied by the actual number of days in the calendar year in
      which the period for which such interest or fee is payable (or compounded)
      ends, and (z) divided by 360 or 365, as the case may be, (ii) the
      principle of deemed reinvestment of interest does not apply to any
      interest calculation under this Agreement, and (iii) the rates of interest
      stipulated in this Agreement are intended to be nominal rates and not
      effective rates or yields.

                                    ADVANCES

SECTION 3.1   ADVANCES.

      The Lender agrees, on the terms and conditions of this Agreement, to make
Advances to the Borrower under the Operating Facility from time to time on any
Business Day prior to the Repayment Date.

SECTION 3.2   PROCEDURE FOR BORROWING.

(1)   Except as provided in Section 3.2(2), each Borrowing shall be made on the
      number of days prior notice specified in Schedule 4.1(2), given not later
      than 11:00 a.m. (Toronto time) by the Borrower to the Lender. Each notice
      of a Borrowing (a "BORROWING NOTICE") shall be in substantially the form
      of Schedule 3.2(1), shall be irrevocable and binding on the Borrower and
      shall

<Page>

                                       27


      specify (i) the requested date of the Borrowing, (ii) the Type of
      Advances comprising the Borrowing, (iii) the aggregate amount of the
      Borrowing, and (v) in the case of a Eurodollar Rate Advance, the initial
      Eurodollar Interest Period. Each Canadian Dollar Advance Borrowing shall
      be in the minimum amount of Cdn.$50,000 and in integral multiples of the
      same and each U.S. Dollar Advance shall be in the minimum amount of
      U.S.$50,000 and in integral multiples of the same. Upon fulfilment of the
      applicable conditions set forth in Article 6, the Lender will make such
      funds available to the Borrower in accordance with Article 2.

(2)   Borrowings may be made as Canadian Prime Rate Advances or Base Rate
      (Canada) Advances on no advance notice to the Lender by utilizing or
      drawing upon (a "UTILIZATION") the Borrower's Canadian Dollar Account (in
      the case of Canadian Prime Rate Advances) or the Borrower's U.S. Dollar
      Account (in the case of Base Rate (Canada) Advances) up to a maximum
      principal amount available such that Accommodations Outstanding do not
      exceed the Lending Limit. Each Utilitization of the Borrower's Accounts in
      the principal amount utilized shall be deemed to be an Accommodation
      Outstanding as at the time such Utilization becomes outstanding.

SECTION 3.3   CONVERSIONS AND ELECTIONS REGARDING ADVANCES.

(1)   Each Advance  shall  initially  be the Type of Advance  specified in the
      applicable Borrowing Notice and shall bear interest at the rate applicable
      to that Type of Advance until (i) in the case of a Eurodollar Rate
      Advance, the end of the initial Eurodollar Interest Period specified in
      the Borrowing Notice, (ii) in the case of a Floating Rate Advance, the
      date on which the Advance is repaid in full or is changed to another Type
      of Advance pursuant to Section 3.3(2), or (iii) in the case of any
      Advance, it is converted to another Type of Accommodation pursuant to
      Section 3.3(2).

(2)   The Borrower may elect to (i) change any Advance to another type of
      Advance in accordance with Section 3.3(3) or convert an Advance to another
      type of Accommodation upon the number of days notice specified in Schedule
      4.1(2) (y) in the case of a Floating Rate Advance, as of any Business Day,
      and (z) in the case of a Eurodollar Advance, as of the last day of the
      Eurodollar Interest Period applicable to the Eurodollar Rate Advance and
      in a principal amount equal to its equivalent currency amount (as
      determined by the Lender as of the date of the Accommodation Notice in
      accordance with the relevant definitions of Equivalent Cdn. $ Amount and
      Equivalent U.S. $ Amount), or (ii) continue any Eurodollar Rate Advance
      for a further Eurodollar Interest Period beginning on the last day of the
      then current Eurodollar Interest Period in accordance with Section 3.3(3).

<Page>

                                       28


(3)   Each election to change from one type of Advance to another type of
      Advance or to continue a Eurodollar Rate Advance for a further Eurodollar
      Interest Period shall be made on the number of days prior notice specified
      in Schedule 4.1(2) given, in each case, not later than 10:30 a.m. (Toronto
      time) by the Borrower to the Lender. Each such notice (an "ELECTION
      NOTICE") shall be given substantially in the form of Schedule 3.3(3) and
      shall be irrevocable and binding upon the Borrower. If the Borrower fails
      to deliver an Election Notice to the Lender for any Eurodollar Rate
      Advance as provided in this Section 3.3, the Eurodollar Rate Advance shall
      be converted (as of the last day of the applicable Eurodollar Interest
      Period) to and be outstanding as a Base Rate (Canada) Advance. The
      Borrower shall not select a Eurodollar Interest Period which conflicts
      with the definition of Eurodollar Interest Period in Section 1.1 or, in
      the opinion of the Lender, with the repayment schedule in Section 2.4.

SECTION 3.4   CIRCUMSTANCES REQUIRING PRIME RATE PRICING.

      If the Lender, acting reasonably, determines, which determination shall be
final, conclusive and binding upon the Borrower, and notifies the Borrower that
(i) by reason of circumstances affecting financial markets generally, deposits
of U.S. Dollars are unavailable to the Lender in Canada, (ii) adequate and fair
means do not exist for ascertaining the applicable interest rate on the basis
provided in the definition of Eurodollar Rate or Base Rate (Canada), as the case
may be, (iii) the making or continuation of any U.S. Dollar Advances has been
made impracticable or unlawful (y) by the occurrence of a contingency (other
than a mere increase in rates payable by the Lender to fund the Advances) which
materially adversely affects the funding of the Operating Facility at any
interest rate computed on the basis of the Eurodollar Rate or the Base Rate
(Canada), as the case may be, or (z) by reason of a change since the date of
this Agreement in any applicable law, order, treaty or official direction, or in
the interpretation thereof by any Governmental Entity affecting the Lender, or
financial markets or institutions generally and which results in the Eurodollar
Rate or the Base Rate (Canada), as the case may be, no longer representing the
effective cost to the Lender of deposits in the market, then:

      (a)   The right of the Borrower to select any affected Type of Advance
            shall be suspended until the circumstances causing the suspension no
            longer exist and the Lender so notifies the Borrower;

      (b)   If any affected Type of Advance is not yet outstanding, any
            applicable Accommodation Notice shall be cancelled and the requested
            Advance shall not be made;

      (c)   If a Eurodollar Rate Advance is already outstanding at any time
            when the right of the Borrower to select Eurodollar Rate Advances
            is

<Page>

                                       29


            suspended, it and all other Eurodollar Rate Advances in the
            same Borrowing shall become Base Rate (Canada) Advances on the
            last day of the then current Interest Period (or on such earlier
            date as may be required to comply with any applicable law, rule,
            regulation, judgment or order) or, if the Borrower does not have
            the right to select Base Rate (Canada) Advances at such time, the
            Eurodollar Rate Advance shall become a Canadian Prime Rate
            Advance on the last day of the then current Eurodollar Interest
            Period applicable to it (or on such earlier date as may be
            required to comply with any applicable law, rule, regulation,
            judgment or order) in a principal amount equal to the Equivalent
            Cdn. $ Amount of the Eurodollar Rate Advance determined on the
            date on which the Advance becomes denominated in Canadian
            Dollars; and

      (d)   If any U.S. Dollar Advance is already outstanding at any time
            when the right of the Borrower to select U.S. Dollar Advances is
            suspended, it and all other U.S. Dollar Advances included in the
            same Borrowing shall become Canadian Prime Rate Advances (i) in
            the  case of a Eurodollar Rate Advance, on the last day of the
            then current Eurodollar Interest Period (or on such earlier date
            as may be required to comply with any applicable law, rule or
            regulation), and (ii)in the case of a Base Rate (Canada)
            Advance, immediately, in a principal amount equal, in each case,
            to the Equivalent Cdn. $ Amount of the related U.S. Dollar
            Advance determined on the date on which the Advance becomes
            denominated in Canadian Dollars.

SECTION 3.5   INTEREST ON ADVANCES.

(1)   The Borrower shall pay interest on the unpaid principal amount of each
      Advance from the date of the Advance until the principal amount of the
      Advance is repaid in full, at the following rates per annum:

      (a)   If and so long as the Advance is a Canadian Prime Rate Advance, at a
            rate per annum equal at all times to the sum of the Canadian Prime
            Rate in effect from time to time plus the Applicable Margin;

      (b)   If and so long as the Advance is a Base Rate (Canada) Advance, at a
            rate per annum equal at all times to the Base Rate (Canada) in
            effect from time to time plus the Applicable Margin; and

      (c)   If and so long as the Advance is a Eurodollar Rate Advance, at a
            rate per annum equal, at all times during each Eurodollar Interest
            Period for such Eurodollar Rate Advance, to the sum of the
            Eurodollar Rate for such Eurodollar Interest Period plus the
            Applicable Margin.

<Page>

                                       30


(2)   Interest on Canadian Prime Rate Advances and Base Rate (Canada) Advances
      shall be calculated daily and payable in arrears (i) on the first Business
      Day of each month, and (ii) when the Advance becomes due and payable in
      full, is repaid, or is converted to another Type of Advance or
      Accommodation. Interest on Eurodollar Rate Advances shall be calculated
      and payable (iii) on the ninetieth day, if any, of the Eurodollar Interest
      Period, and (iv) on the last day of the Eurodollar Interest Period.


                                    ARTICLE 4
                              BANKERS' ACCEPTANCES

SECTION 4.1   ACCEPTANCES AND DRAFTS.

(1)   The Lender agrees, on the terms and conditions of this Agreement and from

      Bankers' Acceptances by accepting Drafts and to purchase such Bankers'
      Acceptances in accordance with Section 4.3(2).

(2)   Each Drawing shall be in a minimum Face Amount and in integral multiples
      of the amount in Schedule 4.1(2) and shall consist of the creation and
      purchase of Bankers' Acceptances or the purchase of Drafts on the same
      day, in each case for the Drawing Price, effected or arranged by the
      Lender in accordance with Section 4.3 and its Operating Commitment.

SECTION 4.2   FORM OF DRAFTS.

      Each Draft presented by the Borrower shall (i) be in a minimum amount of
Cdn $500,000 and in multiples of Cdn $100,000 thereafter, (ii) be dated the date
of the Drawing, and (iii) mature and be payable by the Borrower (in common with
all other Drafts presented in connection with such Drawing) on a Business Day
which occurs approximately 30, 60 or 90 days at the election of the Borrower
after the Drawing Date and on or prior to the Repayment Date and which would
not, in the opinion of the Lender, conflict with the repayment schedule set out
in Section 2.4.

SECTION 4.3   PROCEDURE FOR DRAWING.

(1)   Each Drawing shall be made on notice (a "DRAWING NOTICE") given by the
      Borrower to the Lender not later than 10:00 a.m. (Toronto time) on the

                                       31


      Notice and accept the Drafts and purchase the Bankers' Acceptances so
      created for the Drawing Price. Upon receipt of the Drawing Price and upon
      fulfilment of the applicable conditions set forth in Article 6, the Lender
      shall make funds available to the Borrower in accordance with Article 2.

(3)   The Borrower shall, at the request of the Lender, issue one or more
      non-interest bearing promissory notes (each a "BA EQUIVALENT NOTE")
      payable on the date of maturity of the unaccepted Draft referred to below,
      in such form as the Lender may specify and in a principal amount equal to
      the Face Amount of, and in exchange for, any unaccepted Drafts which the
      Lender has purchased in accordance with Section 4.3(2).

(4)   Bankers' Acceptances purchased by the Lender may be held by it for its own
      account until the contract maturity date or sold by it at any time prior
      to that date in any relevant Canadian market in the Lender's sole
      discretion.

SECTION 4.4   PRESIGNED DRAFT FORMS.

(1)   To enable the Lender to create Bankers' Acceptances in the manner
      specified in this Article 4, the Borrower (i) shall supply the Lender with
      such number of Drafts as it may reasonably request, duly endorsed and
      executed on behalf of the Borrower and (ii) hereby appoints the Lender, as
      its attorney by any authorized signatory of the Lender:

      (a)   To execute, for and on behalf and in the name of the Borrower as
            drawer, and to endorse on its behalf, Drafts in a form in accordance
            with Section 4.2 and which constitute both bills of exchange for the
            purpose of the BILLS OF EXCHANGE ACT (Canada) and depository bills
            for the purpose of the DBNA;

      (b)   To complete the amount, date and maturity date of such Bankers'
            Acceptances; and

      (c)   To deposit such Bankers' Acceptances which have been accepted by the
            Lender with a clearing house (as defined in the DBNA);

      Provided that such acts in each case are to be undertaken by the Lender in
      accordance with instructions given to the Lender by the instructing
      Borrower as provided in Section 4.3(1).

(2)   The Lender will exercise such care in the custody and safekeeping of
      Drafts as it would exercise in the custody and safekeeping of similar
      property owned by it and will, upon request by the Borrower, promptly
      advise the Borrower of the number and designations, if any, of uncompleted
      Drafts held by it for the Borrower. The signature of any officer of the
      Borrower on a Draft may be


<Page>


                                       32


      mechanically reproduced and BA Instruments bearing facsimile signature
      shall be binding upon the Borrower as if they had been manually signed.
      Even if the individuals whose manual or facsimile signature appears on any
      BA Instrument no longer hold office at the date of signature, at the date
      of its acceptance by the Lender or at any time after such date, any BA
      Instrument so signed shall be valid and binding upon the Borrower.

SECTION 4.5   PAYMENT, CONVERSION OR RENEWAL OF BA INSTRUMENTS.

(1)   Upon the maturity of a BA Instrument, the Borrower may (i) elect to
      issue a replacement BA Instrument by giving a Drawing Notice in accordance
      with Section 4.3(1), (ii) elect to have all or a portion of the Face
      Amount of the BA Instrument converted to an Advance by giving a Borrowing
      Notice in accordance with Section 3.2, or (iii) pay, on or before 10:00
      a.m. (Toronto time) on the maturity date for the BA Instrument, an amount
      in Canadian Dollars equal to the Face Amount of the BA Instrument
      (notwithstanding that the Lender may be the holder of it at maturity). Any
      such payment shall satisfy the Borrower's obligations under the BA
      Instrument to which it relates and the Lender shall then be solely
      responsible for the payment of the BA Instrument.

(2)   If the Borrower fails to pay any BA Instrument when due or issue a
      replacement in the Face Amount of such BA Instrument pursuant to Section
      4.5(1), the unpaid amount due and payable shall be converted to a Canadian
      Prime Rate Advance made by the Lender under the applicable Operating
      Facility and shall bear interest calculated and payable as provided in
      Article 3. This conversion shall occur as of the due date and without any
      necessity for the Borrower to give a Borrowing Notice.

SECTION 4.6   CIRCUMSTANCES MAKING BANKERS' ACCEPTANCES UNAVAILABLE.

(1)   If the Lender determines in good faith, which determination shall be
      final, conclusive and binding upon the Borrower, and notifies the Borrower
      that, by reason of circumstances affecting the money market generally,
      there is no market for Bankers' Acceptances, (i) the right of the Borrower
      to request a Drawing shall be suspended until the circumstances causing a
      suspension no longer exist, and (ii) any Drawing Notice which is
      outstanding shall be cancelled and the requested Drawing shall not be
      made.

(2)   The Lender shall promptly notify the Borrower of the suspension of the
      Borrower's right to request a Drawing and of the termination of any
      suspension.

            may exercise in the granting of equitable remedies;

      (f)   AUTHORIZATIONS, ETC. The Borrower and each of the Restricted
            Subsidiaries possess all material authorizations, licenses, permits,

            Liens. The Borrower and each Restricted Subsidiary owns, leases or

      (i)   TRADEMARKS, PATENTS, ETC. The Borrower and each of the Restricted
            Subsidiaries possesses all the trademarks, trade names, copyrights,
            patents and licences necessary for the conduct of their respective

            any of the Restricted Subsidiaries is infringing or is alleged to be
            infringing on the rights of any Person with respect to any patent,
            trademark, trade name, copyright (or any application or registration
            in respect thereof), licence, discovery, improvement, process,
            formula, know-how, data, plan, specification, drawing or the like
            and the Borrower does not know of any facts which might result in

            statutes, by-laws, ordinances, regulations, covenants, restrictions
            or official plans;

      (k)   WORK ORDERS. There are no outstanding work orders requiring, in
            aggregate, expenditures exceeding Cdn. $100,000 relating to the
            Properties from or required by any police or fire department,
            sanitation, health, environmental or factory authorities or from any
            other federal, provincial or municipal authority, nor are any
            matters relating to the Properties under discussion with any such
            departments or authorities relating to work orders;

      (l)   EXPROPRIATION. As at the date hereof, no part of the Properties or
            the buildings located thereon has been taken or expropriated by any
            federal, provincial, municipal or other competent authority nor has

<Page>

                                      42


            any notice or proceeding in respect thereof been given or commenced
            nor is the Borrower or any Restricted Subsidiary aware of any intent
            or proposal to give any such notice or commence any such
            proceedings;

      (m)   NO DEFAULT. Neither the Borrower nor any of its Restricted

                                      61


then the obligation of the Lender to make further Accommodations shall
immediately terminate and the Lender may declare the Accommodations Outstanding,
all accrued interest and Fees and all other amounts payable under this Agreement
to be immediately due and payable, without presentment, demand, protest or
further notice of any kind, all of which are expressly waived by the Borrower.

SECTION 10.2  REMEDIES UPON DEFAULT.

(1)   Upon a declaration that the Accommodations Outstanding are immediately due

      act or omission of the Lender with respect to the Loan Documents or the
      Security shall in any way prejudice or affect the rights, remedies and
      powers of the Lender under the Loan Documents and the Security.

and the Operating Facility provided hereunder at least annually and, in any
event, no later than October 31, 2002.

SECTION 11.2  AMENDMENTS, ETC.

      No amendment or waiver of any provision of any of the Loan Documents, nor
consent to any departure by the Borrower or any other Person from such
provisions, is effective unless in writing and approved by the Lender. Any
amendment, waiver or consent is effective only in the specific instance and for
the specific purpose for which it was given.

SECTION 11.3  WAIVER.

(1)   No failure on the part of the Lender to exercise, and no delay in
      exercising, any right under any of the Loan Documents shall operate as a
      waiver of such

<Page>

                                      62


      right; nor shall any single or partial exercise of any right under
      any of the Loan Documents preclude any other or further exercise of
      such right or the exercise of any other right.

(2)   Except as otherwise expressly provided in this Agreement, the covenants,
      representations and warranties shall not merge on and shall survive the
      initial Accommodation and, notwithstanding such initial Accommodation or
      any investigation made by or on behalf of any party, shall continue in
      full force and effect. The closing of this transaction shall not prejudice
      any right of one party against any other party in respect of anything done
      or omitted under this Agreement or in respect of any right to damages or
      other remedies.

SECTION 11.4  EVIDENCE OF DEBT AND ACCOMMODATION NOTICES.

(1)   The indebtedness of the Borrower resulting from Accommodations under the
      Loan Facilities shall be evidenced by the records of the Lender which
      shall constitute prima facie evidence of such indebtedness.

(2)   Prior to the receipt of any Accommodation Notice, the Lender may act on
      the basis of a notice by telephone (containing the same information as
      would be contained in the Accommodation Notice) believed by it to be from
      an authorized person representing the Borrower. In the event of a conflict
      between the Lender's record of any Accommodation and the Accommodation
      Notice, the Lender's record shall prevail, absent manifest error.

SECTION 11.6  COSTS, EXPENSES AND INDEMNITY.

(1)   The Borrower shall, whether or not the transactions contemplated in this

      any amounts required to compensate the Indemnified Person for, any claim
      or loss suffered by, imposed on, or asserted against, the Indemnified
      Person as a result of, connected with or arising out of (i) the
      preparation, execution and delivery of, preservation of rights under,

      Loan Facilities, the Loan Documents or any  transaction contemplated under
      the Loan Documents, (iii) a default (whether or not constituting a Default
      or an Event of Default) by the Borrower, (iv) any proceedings brought
      against the Indemnified Person due to its entering into of any of the Loan

      Indemnified Person, and (v) the presence of contaminants at, on or under,
      or the discharge or likely discharge of contaminants from, any of the
      Properties or any of the properties now or previously used by the
      Borrower, any of the Restricted Subsidiaries, or the breach of or
      non-compliance with any Environmental Law by any mortgagor, owner or
      lessee of such properties. The Borrower authorizes the Lender to debit the
      Borrower's Accounts for any and all of the costs and expenses referred to
      in paragraphs (i) and (ii) and for all on-site inspections by the Lender
      or its representatives.

(2)   If, with respect to the Lender, (i) any change in any law, rule,
      regulation, judgment or order of general application, or any change in the
      interpretation or application of such law, rule, regulation, judgment or
      order, occurring or becoming effective after this date, or (ii) compliance
      by the Lender with any direction, request or requirement (whether or not
      having the force of law) of any Governmental Entity made or becoming
      effective after the date, has the effect of causing any loss to the Lender
      or reducing the Lender's rate of return by (w) increasing the cost to the
      Lender of performing its obligations under this Agreement or in respect of
      any Accommodations Outstanding (including the costs of maintaining any
      capital, reserve or special deposit requirements but other than a
      reduction resulting from a higher rate or from a change in the calculation
      of income or capital tax relating to the Lender's income or capital in
      general), (x) requiring the Lender to maintain or allocate any capital or
      additional capital or affecting its allocation of capital in respect of
      its obligations under this Agreement or in respect of any Accommodations
      Outstanding, (y) reducing any amount payable to the Lender under this
      Agreement or in respect of any Accommodations Outstanding by any material

      on, or calculated by reference to, any amount received or receivable by
      the Lender under this Agreement or in respect of any Accommodations
      Outstanding, then the Lender may give notice to the Borrower specifying
      the nature of the event giving rise to the loss and the Borrower may
      either (iii) on demand, pay such amounts as the Lender specifies is
      necessary to compensate it for any such loss, or (iv) provided no loss has
      yet been suffered by the Lender or the Borrower has paid the compensating
      amount to the Lender, repay the Accommodations Outstanding and terminate
      the Lender's Commitments. A certificate as to the

<Page>

                                      65


      amount of any such loss submitted in good faith by the Lender to the
      Borrower shall be conclusive and binding for all purposes, absent manifest
      error.

(3)   The Borrower shall pay to the Lender on demand any amounts required to
      compensate the Lender for any loss suffered or incurred by it as a result
      of (i) any payment being made in respect of a BA Instrument, Documentary
      Credit or Advance, other than on the maturity or expiration or on the last
      day of an Eurodollar Interest Period applicable to it, (ii) the failure of
      the Borrower to give any notice in the manner and at the times required by
      this Agreement, (iii) the failure of the Borrower to effect an
      Accommodation in the manner and at the time specified in any Accommodation
      Notice, or (iv) the failure of the Borrower to make a payment or a
      mandatory repayment in the manner and at the time specified in this
      Agreement. A certificate as to the amount of any loss submitted in good
      faith by the Lender to the Borrower shall be conclusive and binding for
      all purposes, absent manifest error.

(4)   The provisions of this Section 11.6 shall survive the termination of this
      Agreement and the repayment of all Accommodations Outstanding. The
      Borrower acknowledges that neither its obligation to indemnify nor any
      actual indemnification by it of the Lender or any other Indemnified Person
      in respect of such Person's losses for the legal fees and expenses shall
      in any way affect the confidentiality or privilege relating to any
      information communicated by such Person to its counsel.

SECTION 11.7  TAXES AND OTHER TAXES.

(1)   All payments to the Lender by the Borrower under any of the Loan Documents
      shall be made free and clear of and without deduction or withholding for
      any and all taxes, levies, imposts, deductions, charges or withholdings
      and all related liabilities (all such taxes, levies, imposts, deductions,
      charges, withholdings and liabilities being referred to as "TAXES")
      imposed by Canada or the United States of America (or any political
      subdivision or taxing authority of it), unless such Taxes are required by
      applicable law to be deducted or withheld. If the Borrower shall be
      required by applicable law to deduct or withhold any such Taxes from or in
      respect of any amount payable under any of the Loan Documents except, as
      provided in the next sentence, (i) the amount payable shall be increased
      (and for greater certainty, in the case of interest, the amount of
      interest shall be increased) as may be necessary so that after making all
      required deductions or withholdings (including deductions or withholdings
      applicable to any additional amounts paid under this Section 11.7(1), the
      Lender receives an amount equal to the amount they would have received if
      no such deduction or withholding had been made, (ii) the Borrower shall
      make such deductions

<Page>

                                      66


      or withholdings, and (iii) the Borrower shall immediately pay the full
      amount deducted or withheld to the relevant Governmental Entity in
      accordance with applicable law.

(2)   The Borrower agrees to immediately pay any present or future stamp or
      documentary taxes or any other excise or property taxes, charges,
      financial institutions duties, debits taxes or similar levies (all such
      taxes, charges, duties and levies being referred to as "OTHER TAXES")
      which arise from any payment made by the Borrower under any of the Loan
      Documents or from the execution, delivery or registration of, or otherwise
      with respect to, any of the Loan Documents.

(3)   The Borrower shall indemnify the Lender for the full amount of Taxes or
      Other Taxes (including, without limitation, any Taxes or Other Taxes
      imposed by any jurisdiction on amounts payable by the Borrower under this
      Section 11.7 paid by the Lender and any liability (including penalties,
      interest and expenses) arising from or with respect to such Taxes or Other
      Taxes, whether or not they were correctly or legally asserted, excluding
      taxes imposed on the Lender's net income, capital taxes or receipts and
      franchise taxes. The Borrower will not be required to indemnify the Lender
      for any Taxes or Other Taxes imposed by reason of the Lender being
      connected with Canada otherwise than merely by lending money to the
      Borrower pursuant to this Agreement. Payment under this indemnification
      shall be made within 30 days from the date the Lender make written demand
      for it. A certificate as to the amount of such Taxes or Other Taxes
      submitted to the Borrower by the Lender shall be conclusive evidence,
      absent manifest error, of the amount due from the Borrower to Lender.

(4)   The Borrower shall furnish, at the request of the Lender, the original or
      a certified copy of a receipt evidencing payment of Taxes or Other Taxes
      made by the Borrower within 30 days after the date of any payment of Taxes
      or Other Taxes.

(5)   If the Lender is, in its sole opinion, entitled to claim a refund or able
      to apply for or otherwise take advantage of any tax credit, tax deduction
      or similar benefit by reason of any withholding or deduction made by the
      Borrower in respect of a payment made by it under this Agreement, which
      payment shall have been increased pursuant to Section 11.7(1), then the
      Lender will use reasonable effort to obtain the refund, credit, deduction
      or benefit and upon credit or receipt of it will pay to the Borrower, the
      amount (if any) not exceeding the increased amount paid by the Borrower,
      as equals the net after-tax value to the Lender of that part of the
      refund, credit, deduction or benefit as it considers is allocatable to
      such withholding or deduction having regard to all of its dealings giving
      rise to similar credits, deductions or benefits in

<Page>

                                      67


      relation to the same tax period and to the cost of obtaining the same.
      Nothing contained in this Section 11.7(5) shall interfere with the right
      of the Lender to arrange its tax affairs in whatever manner it deems fit
      and in particular, the Lender shall be under no obligation to claim relief
      from its corporate profits or similar tax liability in respect of any
      deduction or withholding in priority to any other relief, claims, credits
      or deductions available to it and the Lender shall not be obligated to
      disclose to the Borrower any information regarding its tax affairs, tax
      computations or otherwise.

(6)   The provisions of this Section 11.7 shall survive the termination of the
      Agreement and the repayment of all Accommodations Outstanding.

SECTION 11.8  SUCCESSORS AND ASSIGNS.

(1)   This Agreement shall become effective when executed by the Borrower and
      the Lender and after that time shall be binding upon and enure to the
      benefit of the Borrower and the Lender and their respective successors and
      permitted assigns.

(2)   The Borrower shall not have the right to assign its rights or obligations
      under this Agreement or any interest in this Agreement without the prior
      consent of the Lender, which consent may be arbitrarily withheld.

(3)   At any time prior to the occurrence of an Event of Default, the Lender may
      with the prior written consent of the Borrower (which consent, in the case
      of the Borrower, is not to be unreasonably withheld), assign all or any
      part of its interest in the Loan Facilities to one or more Persons (each
      an "ASSIGNEE") provided that such assignment is not made to a Person the
      identity of which would have the effect of imposing additional obligations
      upon the Borrower as a result of the application of Section 11.7 hereof.
      At any time after the occurrence of an Event of Default, the Lender may
      assign all or any part of its interest in the Loan Facilities to an
      Assignee without any requirement for notice to or consent of the Borrower
      or any other Person. In the case of an assignment, the Assignee shall have
      the same rights and benefits and be subject to the same limitations under
      the Loan Documents as it would have if it was a Lender.

SECTION 11.9  RIGHT OF SET-OFF.

      Following the occurrence, and during the continuance of an Event of
Default, the Lender is authorized at any time and from time to time, to the
fullest extent permitted by law (including general principles of common-law), to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by it to or for the credit or the account of the Borrower against any and all of
the obligations of the Borrower under

                                      68


any of the Loan Documents. If an obligation is unascertained, the Lender may, in
good faith, estimate the obligation and exercise its right of set-off in respect
of the estimate, subject to providing the Borrower with an accounting when the
obligation is finally determined. The Lender shall promptly notify the Borrower
after any set-off and application is made by it, provided that the failure to
give notice shall not affect the validity of the set-off and application. The
rights of the Lender under this Section 11.9 are in addition to any other rights
and remedies (including all other rights of set-off) which the Lender may have.

SECTION 11.10 JUDGMENT CURRENCY.

(1)   If, for the purposes of obtaining judgment in any court, it is necessary
      to convert a sum due to the Lender in any currency (the "ORIGINAL
      CURRENCY") into another currency (the "OTHER CURRENCY"), the parties
      agree, to the fullest extent that they may effectively do so, that the
      rate of exchange used shall be that at which, in accordance with normal
      banking procedures, the Lender could purchase the Original Currency with
      the Other Currency on the Business Day preceding the day on which final
      judgment is given or, if permitted by applicable law, on the day on which
      the judgment is paid or satisfied.

(2)   The obligations of the Borrower in respect of any sum due in the Original
      Currency from it to the Lender under any of the Loan Documents shall,
      notwithstanding any judgment in any Other Currency, be discharged only to
      the extent that on the Business Day following receipt by the Lender of any
      sum adjudged to be so due in the Other Currency, the Lender may, in
      accordance with normal banking procedures, purchase the Original Currency
      with such Other Currency. If the amount of the Original Currency so
      purchased is less than the sum originally due to the Lender in the
      Original Currency, the Borrower agrees, as a separate obligation and
      notwithstanding the judgment, to indemnify the Lender, against any loss,
      and, if the amount of the Original Currency so purchased exceeds the sum
      originally due to the Lender in the Original Currency, the Lender shall
      remit such excess to the Borrower.

SECTION 11.11 INTEREST ON AMOUNTS.

      Except as may be expressly provided otherwise in this Agreement, all
amounts owed by the Borrower to the Lender which are not paid when due (whether
at stated maturity, on demand, by acceleration or otherwise) shall bear interest
(both before and after default and judgment), from the date on which such amount
is due until such amount is paid in full, payable on demand, at a rate per annum
equal at all times to (i) in the case of an amount payable in U.S. Dollars, the
sum of the Base Rate (Canada) in effect from time to time, the Applicable Margin

                                      69


and 2%, and (ii) in the case of an amount payable in Canadian Dollars, the sum
of the Canadian Prime Rate in effect from time to time, the Applicable Margin
and 2%.

SECTION 11.12 GOVERNING LAW.

      This Agreement shall be governed by and interpreted and enforced in
accordance with the laws of the Province of Ontario and the federal laws of
Canada applicable therein.

SECTION 11.13 COUNTERPARTS.

      This Agreement may be executed in any number of counterparts and all of
such counterparts taken together shall be deemed to constitute one and the same
instrument.

SECTION 11.14 FACSIMILE SIGNATURES.

      This Agreement may be executed by facsimile signature, in which case the
party executing by facsimile shall forward an original counterpart thereof to
the other party but failure to so deliver shall not invalidate this Agreement.

SECTION 11.15 CONSENT TO JURISDICTION.

      The Borrower hereby irrevocably submits to the jurisdiction of any Ontario
court sitting in Toronto in any action or proceeding arising out of or relating
to the Loan Documents and hereby irrevocably agrees that all claims in respect
of any such action or proceeding may be heard and determined in such Ontario
court. The Borrower and each Restricted Subsidiary hereby irrevocably waive, to
the fullest extent they may effectively do so, the defense of an inconvenient
forum to the maintenance of such action or proceeding. The Borrower and each
Restricted Subsidiary agree that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law. Nothing in this
Section 11.15 shall affect the right of the Lender to bring any action or
proceeding against the Borrower or each Restricted Subsidiary or their property
in the courts of other jurisdictions.
