     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

SECTION 2.10   APPLICATION OF PAYMENTS AND PREPAYMENTS.

(1)  All amounts received by the Lender from or on behalf of the Borrower and

     Advances which is due and owing, (iv) fourth, in reduction of the

(2)  Subject to the next following sentence, whenever any payment hereunder
     shall be stated to be due on a day other than a Business Day, such payment
     shall be made on the next succeeding Business Day, and such extension of
     time shall in such case be included in the computation of interest or Fees,
     as the case may be.

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.

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 ERROR! REFERENCE SOURCE
     NOT FOUND., 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

     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

<Page>

                                       29

     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 ERROR!
     REFERENCE SOURCE NOT FOUND. (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).

(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 ERROR! REFERENCE SOURCE NOT FOUND. 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 ERROR! REFERENCE SOURCE NOT FOUND. 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

<Page>

                                       30

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
          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.

     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.

(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

     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

<Page>

                                       32

longer period as may be approved by the Lender) 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
     number of days notice specified in Schedule ERROR! REFERENCE SOURCE NOT

     Borrower and shall specify (i) the Drawing Date, (ii) the aggregate Face
     Amount of Drafts to be accepted and purchased, and (iii) the contract
     maturity date for the Drafts.

(2)  Not later than 2:00 p.m. (Toronto time) on an applicable Drawing Date, the
     Lender shall complete one or more Drafts in accordance with the Drawing
     Notice and accept the Drafts and purchase the Bankers' Acceptances so
     created for the Drawing Price. Upon fulfilment of the applicable conditions
     set forth in ARTICLE 7, the Lender shall make funds available to the
     Borrower in accordance with Article 2.

(3)  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

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

     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;

<Page>

                                       33

     (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 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 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.

SECTION 5.1    DOCUMENTARY CREDITS.

     The Lender agrees, on the terms and conditions of this Agreement, to issue
Documentary Credits under the Operating Facility only for the account of the
Borrower from time to time on any Business Day prior to the Repayment Date upon
execution of the Lender's prevailing standard form documentation in relation
thereto, including the applicable application and indemnity.

SECTION 5.2         REIMBURSEMENTS OF AMOUNTS DRAWN.

     If the Borrower fails to pay to the Lender the amount drawn under any
Documentary Credit, the unpaid amount due and payable shall be converted
automatically as of such date, and without the Borrower having to give any
Borrowing Notice pursuant to Section 3.2, to (i) a Canadian Prime Rate Advance,
in the case of a Documentary Credit denominated in Canadian Dollars, and (ii) a
Base Rate (Canada) Advance, in the case of a Documentary Credit denominated in
U.S. Dollars, in each case under the Operating Facility.

SECTION 5.3    FEES.

     Credit equal to 1.2% per annum of the Face Amount (and if outstanding in
     U.S. Dollars, on the the Equivalent Cdn. $ Amount of its Face Amount), in
     each case, for the period during which the Documentary Credit is

          principal amount exceeding Cdn.$50,000 (or the equivalent amount in
          any other currency) when such amount becomes due and payable (whether

          basis pursuant to Section 2.5(1) or if such Borrowing Base Certificate

     (m)  The Lender shall determine in good faith, but otherwise in its sole

          materially adversely affects the Collateral; or

     (n)  The  audited  consolidated  financial  statements  of the  Borrower

then the obligation of the Lender to make further Accommodations shall

                                       63

SECTION 10.2   REMEDIES UPON DEFAULT.

(1)  Upon a declaration that the Accommodations Outstanding are immediately due
     and payable pursuant to Section 10.1, the Lender may commence such legal
     action or proceedings as it, in its sole discretion, deems expedient,
     including, the commencement of enforcement proceedings under the Loan
     Documents all without any additional notice, presentation, demand, protest,
     notice of dishonour, entering into of possession of any property or assets,
     or any other action or notice, all of which are expressly waived by the
     Borrower.

(2)  The rights and remedies of the Lender under the Loan Documents are
     cumulative and are in addition to, and not in substitution for, any other
     rights or remedies. Nothing contained in the Loan Documents with respect to
     the indebtedness or liability of the Borrower to the Lender, nor any 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.

     The Lender and the Borrower agree to review the terms of this Agreement and
the Loan Facilities provided hereunder by October 31, 2003 and at least annually
thereafter.

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 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

<Page>

                                       64

     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 11.5   NOTICES, ETC.

     Any notice, direction or other communication to be given under this
Agreement shall, except as otherwise permitted, be in writing and given by

SECTION 11.6   COSTS, EXPENSES AND INDEMNITY.

(1)  The Borrower shall, whether or not the transactions contemplated in this
     Agreement are completed, indemnify and hold the Lender (the "INDEMNIFIED
     PERSON") harmless from, and shall pay to such Indemnified Person on demand
     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, interpretation of,
     maintenance of, perfection of, enforcement of, or refinancing,
     renegotiation or restructuring of, the Loan Documents and any related
     amendment, waiver or consent, (ii) any advice of counsel as to the

<Page>

                                       66

     rights and duties of the Lender with respect to the administration of the
     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
     Documents and performing its obligations under the Loan Documents except to
     the extent caused by the gross negligence or wilful misconduct of the
     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
     amount, (z) causing the Lender to make any payment or to forego any return
     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>

                                       67

     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>

                                       68

     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>

                                       69

     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

<Page>

                                       70

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

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.
