assist the Borrower in financing the repayment of its indebtedness to J.P.
Morgan Bank Canada; and (ii) for day to day operating requirements of the

Advances under Facility A from time to time and obtain further Advances under
Facility A from time to time; provided that the principal amount of Outstanding
Advances at any time under Facility A shall not exceed the Facility A Limit at
such time.

2.04 REPAYMENT/MATURITY/EXTENSION

      (a) The Obligations under Facility A shall become due and payable on the
earliest of: (i) the Acceleration Date; and (ii) the Facility A Maturity Date.

      (b) Provided that no Default or Event of Default has occurred and is

Date in effect at any time, by written notice to BMO given no later than ninety
(90) days prior to the Facility A Maturity Date then in effect. BMO may from
time to time in its sole discretion extend the Facility A Maturity Date for a
period not to exceed 364 days from the Facility A Maturity Date then in effect
(and for greater certainty any such extended date from time to time shall be the
"Facility A Maturity Date" for all purposes of this Agreement). BMO shall inform
the Borrower of its decision regarding such requested extension within sixty
(60) days after receipt of the said request.

            of third parties, in all major currencies offered by BMO, to a

            has completed all documentation required by BMO in respect of each
            Letter of Credit including BMO's standard form of application and

      provided that Bankers' Acceptances, LIBOR Loans and Letters of Credit will
not be issued with a maturity date later than the Facility A Maturity Date or
which in BMO's opinion in its sole discretion could result in the Facility A
Limit being exceeded at any time; except that in BMO's sole discretion a Letter
of Credit may be issued with a maturity date later than the Facility A Maturity
Date (or may contain a clause providing for automatic renewal in the absence of
notice by BMO to the beneficiary thereunder which if so renewed would result in
such Letter of Credit expiring after the Facility A Maturity Date) if at the
time of issuance thereof arrangements satisfactory to BMO in its sole discretion
are made to secure such Letter of Credit with cash collateral from and after the
Facility A Maturity Date. The Borrower may convert Outstanding Advances under
Facility A in the form of any above Availment Option into another form of
Availment Option, subject to and in accordance with the terms and conditions of
this Agreement (but for greater certainty, Bankers' Acceptances, LIBOR Loans and
Letters of Credit may not be converted into another Availment Option prior to
the maturity thereof).

2.07 FACILITY A LIMIT

      (a) In this Agreement, "Facility A Limit" means, at any time, an amount
equal to the lesser of: (A) the Facility A Maximum Amount; and (B) an amount
determined at such time as follows:

            (i)   75% of the Eligible Accounts Receivable owing to the Borrower
                  by account debtors domiciled in Canada; plus

            (ii)  60% of the Eligible Accounts Receivable owing to the Borrower
                  by account debtors domiciled in the United States; plus

            (iii) the lesser of (x) $2,000,000 and (y) 50% of the value of the
                  Eligible Inventory (determined at the lower of cost and market
                  value); less

            (iv)  the Potential Statutory Priority Amount at
                  such time.

      (b) The Facility A Limit shall be adjusted as at the date of each receipt
by the Agent of a Borrowing Base Certificate and shall remain in effect until
receipt by the Agent of a subsequent Borrowing Base Certificate; provided that
if the Agent does not receive a Borrowing Base Certificate on or before the date
required pursuant to paragraph 7.04(a), the Facility A Limit shall be reduced to
the lowest Facility A Limit in the preceding twelve (12) months or such lower
amount as may be estimated by the Agent, acting reasonably, to be the Facility A
Limit determined in accordance with the formula in paragraph 2.07(a), until such
time as a Borrowing Base Certificate is thereafter received by the Agent. BMO
shall have no obligation to make any portion of an Advance under Facility A to
the extent that after making such Advance the Obligations under Facility A would
exceed the Facility A Limit then in effect. If at any time the Obligations under
Facility A exceed the Facility A Limit then in effect, the Borrower shall within
two (2) Business Days of written or verbal notice by BMO pay to BMO the (c)
principal amount required to reduce the Obligations under Facility A to an
amount not greater than the Facility A Limit then in effect.

2.08 CANCELLATION OF UNUSED PORTION OF FACILITY A

      The Borrower may from time to time upon two (2) Business Days' prior
written notice to the Agent, without penalty or fee, cancel any unadvanced
portion of Facility A,
<PAGE>
                                      -26-

in which event the Facility A Maximum Amount shall be reduced by the amount so
cancelled.

3.01 ESTABLISHMENT OF FACILITY B

      Subject to the terms and conditions in this Agreement, each Facility B
Lender hereby establishes a non-revolving credit facility for the Borrower in
the maximum principal amount indicated opposite such Lender's name in Exhibit
"A" under the heading "Facility B Commitments". The said credit facilities are
established by the Facility B Lenders severally and not jointly, and are
hereinafter collectively referred to as "Facility B". Each Advance by a Facility

Share of Facility B.

3.02 PURPOSE AND TRANCHES

      Advances under Facility B may be used by the Borrower for the following
purposes:

      (a) upon the satisfaction of all applicable conditions precedent, a single

days after the date of this Agreement (unless extended in writing by the Agent
on behalf of the Lenders) not in excess of Forty Million Dollars ($40,000,000),
the proceeds of which shall be used by the Borrower to repay all indebtedness
and obligations due by the Borrower to J.P. Morgan Bank Canada;

      (b) upon the satisfaction of all applicable conditions precedent, a single
Advance (herein called "Tranche B-2") shall be made on or before September 30,
2003 not in excess of the amount of the Facility B Limit less the amount of the
Advance previously made under Tranche B-1, the proceeds of which shall be used
by the Borrower to make a Distribution to Holdings, or for such other purpose as
may be approved in writing by the Agent on behalf of the Lenders; and

      (c) upon the satisfaction of all applicable conditions precedent, a single
Advance (herein called "Tranche B-3") shall be made on or before September 30,
2003 not in excess of the amount of the Facility B Limit less the amount of the
Advances previously made under Tranche B-1 and Tranche B-2, the proceeds of
which may be used by the Borrower to make a Distribution to Holdings, or for
such other purpose as may be approved in writing by the Agent on behalf of the
Lenders;

      and for greater certainty, no further Advances will be permitted under
Facility B, and the unadvanced portion of Facility B shall be permanently
cancelled, after the earliest to occur of (i) September 30, 2003 and (ii) the
making of an Advance under Tranche B-3.

                                      -28-

3.03 NON-REVOLVING NATURE

      Facility B is a non-revolving facility. Any Repayment under Facility B may
not be reborrowed.

3.04 REPAYMENT/MATURITY/EXTENSION

      (a) The Obligations under Facility B shall become due and payable on the
earliest of: (i) the Acceleration Date; and (ii) the Facility B Maturity Date.

      (b) Prior to the Acceleration Date, the Borrower shall make Repayments to
the Agent in respect of the Outstanding Advances under Tranche B-1 in an amount
per month equal to the Advance made under Tranche B-1 divided by 120 (or such
lesser number as may be requested by the Borrower in writing at or before the
time of such Advance); such payments to be made on the last day of each and
every month, the first such monthly payment to be made on the last day of the
month following the month in which the Advance under Tranche B-1 is made. The
remaining balance of the Outstanding Advances under Tranche B-1 shall be paid on
the Facility B Maturity Date.

      (c) Prior to the Acceleration Date, the Borrower shall make Repayments to
the Agent in respect of the Outstanding Advances under Tranche B-2 in an amount
per month equal to the Advance made under Tranche B-2 divided by 120 (or such
lesser number as may be requested by the Borrower in writing at or before the
time of such Advance); such payments to be made on the last day of each and
every month, the first such monthly payment to be made on the last day of the
month following the month in which the Advance under Tranche B-2 is made. The
remaining balance of the Outstanding Advances under Tranche B-2 shall be paid on
the Facility B Maturity Date.

      (d) Prior to the Acceleration Date, the Borrower shall make Repayments to
the Agent in respect of the Outstanding Advances under Tranche B-3 in an amount
per month equal to the Advance made under Tranche B-3 divided by 120 (or such
lesser number as may be requested by the Borrower in writing at or before the
time of such Advance); such payments to be made on the last day of each and
every month, the first such monthly payment to be made on the last day of the
month following the month in which the Advance under Tranche B-3 is made. The
remaining balance of the Outstanding Advances under Tranche B-3 shall be paid on
the Facility B Maturity Date.

      (e) In addition to the Repayments required under paragraphs 3.04(b), (c)
and (d), if at the end of the Fiscal Year ending September 30, 2003 or at the
end of any subsequent Fiscal Year the Outstanding Advances under Facility B as
at the end of such Fiscal Year are greater than Thirty Million Dollars
($30,000,000), then on or before the date required hereunder for the delivery of
the Yearend Financial Statements of the Companies for such Fiscal Year the
Borrower shall make a Repayment in an amount equal to the lesser of: (i)
forty-five percent (45%) of the Excess Cash Flow in such Fiscal Year and (ii)
such amount as will result in the reduction of the Outstanding Advances under
Facility B to $30,000,000.
<PAGE>
                                      -29-

      (f) In addition to the Repayments required under paragraphs 3.04(b), (c),
(d) and (e), if any Company receives proceeds from:

      (i)   a policy of insurance, except to the extent that such proceeds are
            permitted to be retained by such Company as provided in paragraph
            7.01(i); or

      (ii)  a transaction involving the sale, leasing or other disposition of
            any individual asset or group of related assets (other than
            inventory sold in the ordinary course of business) in one or a
            series of related transactions, unless, within 90 days after such
            disposition, the Borrower has either reinvested such proceeds in
            similar assets or has entered into a binding commitment to do so
            within a further period of 90 days;

      then the Borrower will pay such proceeds (net of transaction expenses and
usual adjustments, if applicable) to the Agent as a Prepayment; such payment to
be made within three (3) Business Days after receipt of such proceeds in the
case of clause (i) above, and within 95 days from the date of the transaction in
the case of clause (ii) above.

      (g) Provided that no Default or Event of Default has occurred and is
continuing, the Borrower may request an extension of the Facility B Maturity
Date in effect at any time, by written notice to the Agent on behalf of the
Facility B Lenders given no later than ninety (90) days prior to the Facility B
Maturity Date then in effect. Subject to obtaining the prior written consent of
all other Lenders, the Facility B Lenders may from time to time in their sole
discretion extend the Facility B Maturity Date (and for greater certainty any
such extended date from time to time shall be the "Facility B Maturity Date" for
all purposes of this Agreement). The Agent shall inform the Borrower of the
decision of the Facility B Lenders regarding such requested extension within
sixty (60) days after receipt of the said request.

3.05 AVAILMENT OPTIONS

      Subject to the restrictions contained in this Article III and the
exceptions indicated below, the Borrower may receive Advances under Facility B
from the Facility B Lenders (subject to the restrictions set out below) by any
one or more of the following Availment Options (or any combination thereof):

      (i)   Canadian Dollar Loans in minimum amounts of $500,000 and multiples
            of $100,000; or

      (ii)  Bankers' Acceptances from the BA Lenders in minimum amounts of
            $500,000 and multiples of $100,000; or

      (iii) BA Equivalent Note Loans from the Non-BA Lenders in minimum amounts
            of $500,000 and multiples of $100,000; or

<PAGE>
                                      -30-

      provided that Bankers' Acceptances, BA Equivalent Note Loans and
Fixed-Rate Term Loans will not be issued with a maturity date later than the
Facility B Maturity Date or which could result in the Facility B Limit being
exceeded at any time. The Borrower may convert Outstanding Advances under
Facility B in the form of any above Availment Option into another said form of
Availment Option, subject to and in accordance with the terms and conditions of
this Agreement (but for greater certainty, Bankers' Acceptances, BA Equivalent
Note Loans and Fixed-Rate Term Loans may not be converted into another Availment
Option prior to the maturity thereof).

3.06 INTEREST AND FEES

      In respect of Advances under Facility B, the Borrower receiving such
Advance shall pay to the Agent on behalf of the Facility B Lenders:

      (a) interest on Canadian Dollar Loans at the Adjusted Prime Rate plus the
Applicable Margin per annum, payable monthly in arrears on the last day of each
and every month;

      (b) in respect of each Bankers' Acceptance, a stamping fee equal to the
face amount of such Bankers' Acceptance, multiplied by the Applicable Margin,
multiplied by the number of days to maturity of the Bankers' Acceptance (but
excluding the day on which the Bankers' Acceptance matures), and divided by 365,
payable at the time of acceptance;

      (c) in respect of each BA Equivalent Note, a stamping fee equal to the
face amount of such BA Equivalent Note, multiplied by the Applicable Margin,
multiplied by the number of days to maturity of the BA Equivalent Note (but
excluding the day on which the BA Equivalent Note matures), and divided by 365,
payable at the time of acceptance;

      (d) interest on Fixed-Rate Term Loans at a rate determined pursuant to
section 3.07, payable monthly in arrears on the last day of each and every
month; and

      (e) a standby fee equal to one-half of one percent (0.50%) per annum of
the amount, calculated on a daily basis, of the difference between (i) the
Facility B Limit and (ii) the Outstanding Advances under Facility B, payable
quarterly in arrears on the last day of each Fiscal Quarter.

      With respect to any Availment Option under Facility B, "Applicable Margin"
means, in respect of any Fiscal Quarter, the percentage in the column relating
to such Availment Option in the following table which corresponds to the
condition described in the first column (determined in respect of the fiscal
period comprised of such Fiscal Quarter and the immediately preceding three
Fiscal Quarters); provided that until the Interim Financial Statements and
Compliance Certificate for the period ending June 30, 2002 are delivered by the
Borrower to the Agent in accordance with section 7.04(b), the Applicable Margin
for each Availment Option shall be the percentage in the column relating to such
Availment Option in the first row of such table.

3.07 FIXED-RATE TERM LOANS

      The Borrower may at any time at its option request Advances under Facility
B from the Lenders, respectively, by way of Canadian Dollar Loans bearing
interest for a specified period at fixed rates, in the following manner (and
each such Canadian Dollar Loan made by a Lender is here called a "Fixed-Rate
Term Loan"). The Borrower may also at any time request the Conversion of all or
any part of the Outstanding Advances under an Availment Option other than
Fixed-Rate Term Loans (but in the case of Bankers' Acceptances and BA Equivalent
Note Loans, only upon the maturity thereof) to Fixed-Rate Term Loans in the same
manner. The Borrower shall deliver a written request to the Agent specifying the
aggregate principal amount of the Fixed-Rate Term Loans requested, the proposed
commencement date of such Fixed-Rate Term Loans (which may not be earlier than
five (5) Business Days after the date of delivery of such request), and the
proposed maturity date for such Fixed-Rate Term Loans (which may not be later
than the earlier of: (i) five (5) years from the said proposed commencement
date; and (ii) the Facility B Maturity Date then in effect). The Agent shall
promptly notify the Lenders of such request and the principal amount of the
Fixed-Rate Term Loan to be made by each Lender (which shall be approximately
equal to the aggregate amount of the said Fixed- Rate Term Loans requested by
the Borrower multiplied by such Lender's Proportionate Share of Facility B). At
least one (1) Business Day prior to the commencement date of such Fixed-Rate
Term Loans proposed by the Borrower, each Lender shall advise the
<PAGE>
                                      -32-

Agent whether it will make a Fixed-Rate Term Loan in the amount and for the
period requested, and if so, the interest rate which will apply to such
Fixed-Rate Term Loan (determined by such Lender as its cost of funds applicable
to the principal amount of such requested Fixed-Rate Term Loan for the period
requested, plus the Applicable Margin set out in section 3.06). If all Lenders
agree to make Fixed-Rate Term Loans in the aggregate principal amount requested
by the Borrower, on the day prior to the commencement date proposed by the
Borrower for such Fixed-Rate Term Loans the Agent shall advise the Borrower in
writing of the interest rate offered by each Lender in respect of the Fixed-Rate
Term Loan offered by it. On the same day the Borrower may by notice in writing
to the Agent accept the said offers made by all, but not less than all of the
Lenders. For greater certainty, Fixed-Rate Term Loans are available under
Facility B only if concurrently made by all Lenders in the manner described
above.

3.08 VOLUNTARY PREPAYMENTS

      The Borrower may from time to time, upon forty-five (45) Business Days'
prior written notice to the Agent make a Prepayment in respect of any
Outstanding Advances under Facility B in a minimum amount and in multiples of
$1,000,000, provided that such Prepayment is not made, directly or indirectly,
from the proceeds of Funded Debt (unless a Prepayment is made in respect of all
Outstanding Advances under Facility B); and provided further that in respect of
any Prepayment of a Bankers' Acceptance, BA Equivalent Note Loan or a Fixed-Rate
Term Loan the Borrower shall concurrently pay all applicable breakage costs
pursuant to section 5.12 (but otherwise no penalty or fee shall be payable in
connection with such Prepayment). The Facility B Limit shall be automatically
and permanently reduced by the amount of any such Prepayment. The Borrower may
also from time to time upon forty-five (45) Business Days' prior written notice
to the Agent, cancel any unadvanced portion of Facility B, in which event the
Facility B Limit shall be reduced by the amount so cancelled. For greater
certainty, the forty-five (45) Business Day notice period required to cancel any
unadvanced portion of Facility B may run concurrently with the forty-five (45)
Business Day notice period required for a Prepayment of any Outstanding Advances
under Facility B.

                        ARTICLE IV - MASTERCARD FACILITY

4.01 ESTABLISHMENT OF FACILITY

      Subject to the terms and conditions in this Agreement, BMO hereby
establishes a credit facility for the Borrower in the maximum principal amount
of Five Hundred Thousand Dollars ($500,000.00) (the "Mastercard Facility"). BMO
shall not have the right to assign or grant a participation in the MasterCard
Facility in whole or in part to any other Person.

4.02 PURPOSE OF FACILITY

      Advances under the MasterCard Facility shall be used by the Borrower for
general corporate purposes, including purchasing supplies and funding
miscellaneous business expenses incurred by officers and employees of the
Borrower.

4.03 MASTERCARD FACILITY LIMIT

      The Outstanding Advances at any time under the MasterCard Facility shall
not exceed the MasterCard Facility Limit. BMO shall have no obligation to make
an Advance under the MasterCard Facility if after making such Advance the
Obligations under the MasterCard Facility would exceed the MasterCard Facility
Limit. If at any time the Obligations under the MasterCard Facility exceed the
MasterCard Facility Limit, the Borrower shall pay to BMO the principal amount
required to reduce the Obligations under the MasterCard Facility to an amount
not greater than the MasterCard Facility Limit, in accordance with the terms and
conditions contained in the MasterCard agreement referred to in section 4.04.

4.04 TERMS AND CONDITIONS

      The Borrower may receive Advances under the MasterCard Facility by way of
debits through the use of corporate cards issued by BMO to officers and
employees of the Borrower at the Borrower's request upon the completion of a
MasterCard agreement and all other necessary documentation required by BMO.

4.05 REPAYMENT

      The Obligations under the MasterCard Facility shall become due and payable
upon the earliest to occur of (i) the issuance by BMO of a demand for payment of
all Obligations of the Borrower under the MasterCard Facility; and (ii) the
Acceleration Date. Until such time, the Obligations under the MasterCard
Facility shall be payable monthly in accordance with the terms of the MasterCard
agreement made between the Borrower and BMO.

                         ARTICLE V - GENERAL CONDITIONS

5.01 MATTERS RELATING TO INTEREST

      (a) Unless otherwise indicated, interest on any outstanding principal
amount shall be calculated daily and shall be payable monthly in arrears on the
last day of each and every month. If the last day of a month is not a Business
Day, the interest payment due on such day shall be made on the next Business
Day, and interest shall continue to accrue on the said principal amount during
such stub period and shall also be paid on such next Business Day.
(Alternatively, in the Agent's discretion, acting reasonably, interest accruing
on the said principal amount during such stub period shall not be payable on
such next Business Day, but shall instead be payable on the last day of the
following month.) Interest shall accrue from and including the day upon which an
Advance is made or is deemed to have been made, and ending on but excluding the
day on which such Advance is repaid or satisfied. Any changes in the Adjusted
Prime Rate or U.S. Base Rate shall cause an immediate adjustment of the interest
rate applicable to Canadian Dollar Loans or U.S. Dollar Loans as the case may
be, from and after such change, without the necessity of any notice to the
Borrower.

      (b) Unless otherwise stated, in this Agreement if reference is made to a
rate of interest, fee or other amount "per annum" or a similar expression is
used, such interest, fee or other amount shall be calculated on the basis of a
year of 365 or 366 days, as the case may be. If the amount of any interest, fee
or other amount is determined or expressed on the basis of a period of less than
one year of 365 or 366 days, as the case may be, the equivalent yearly rate is
equal to the rate so determined or expressed, divided by the number of days in
the said period, and multiplied by the actual number of days in that calendar
year.

      (c) Notwithstanding any other provisions of this Agreement, if the amount
of any interest, premium, fees or other monies or any rate of interest
stipulated for, taken, reserved or extracted under this Agreement or the
Security would otherwise contravene the provisions of section 347 of the
Criminal Code (Canada), section 8 of the Interest Act (Canada) or any successor
or similar legislation, or would exceed the amounts which the Agent is legally
entitled to charge and receive under any law to which such compensation is
subject, then such amount or rate of interest shall be reduced to such maximum
amount as would not contravene such provision; and to the extent that any excess
has been charged or received the Agent shall apply such excess against the
Outstanding Advances and refund any further excess amount.

      (d) Any change in the Applicable Margin in respect of any Availment Option
under Facility A or Facility B shall be determined by the Agent based upon the
information contained in the most recent Compliance Certificate received by the
Agent, and shall take effect commencing on the fifth day following receipt of
such Compliance Certificate by the Agent. The parties agree to make all
necessary adjustments in this
<PAGE>
                                      -35-

regard, including adjustments retroactive to such effective date. If the Agent
does not receive a Compliance Certificate on the date required pursuant to
paragraph 7.04(b), the Applicable Margin in respect of each Availment Option
under Facility A shall be as set out in the second row of the chart in section
2.06, and the Applicable Margin in respect of each Availment Option under
Facility B shall be as set out in the second row of the chart in section 3.06,
and each such Applicable Margin shall remain in effect until the fifth day

            Days' notice is required before 10:00 a.m. Toronto time; and

      (vii) notwithstanding the foregoing, if the Advance relates to the

<PAGE>
                                      -36-

Rollover Notice, Conversion Notice or Repayment Notice, as the case may be,
attached hereto as Exhibits. All such notices in respect of Facility A shall be
given to BMO at its address set out in Exhibit "A"; and all other notices shall
be given to the Agent at its address set out in section 13.06.

      (c) If notice is not provided as contemplated herein with respect to the
maturity of any Bankers' Acceptance, BA Equivalent Note Loan or LIBOR Loan, the
Lender in question may convert such Bankers' Acceptance, BA Equivalent Note Loan
or LIBOR Loan upon its maturity into a Canadian Dollar Loan or a U.S. Dollar
Loan.

      (d) Any conversion from one form of Availment Option to another shall be
subject to satisfaction of all of the terms and conditions applicable to the
form of the new Availment Option as herein provided.

5.03 PROCEDURES RE DRAWDOWNS, ROLLOVERS, CONVERSIONS, REPAYMENTS

      (a) Upon receipt of a Drawdown Request under any Credit Facility, the
Agent shall promptly notify each Lender under such Credit Facility of the
contents thereof and such Lender's Proportionate Share of the Advance. Such
Drawdown Request shall not thereafter be revocable.

      (b) Each Advance shall be made by the applicable Lenders to the Agent at
its address referred to in section 13.06; provided that the Agent may designate
other addresses by notice in writing to the Lenders from time to time. Each
Lender shall make available its Proportionate Share of each said Advance to the
Agent. Unless the Agent determines that any condition of the Advance has not
been satisfied or waived, the Agent shall make the funds so received from the
Lenders available to the Borrower, or as the Borrower shall direct, by 3:00 p.m.
(Toronto time) on the requested date of the Advance. No Lender shall be
responsible for any other Lender's obligation to make available its
Proportionate Share of the said Advance.

      (c) If the Borrower requests an Advance under any Credit Facility by way
of Bankers' Acceptances, each Lender under such Credit Facility shall, on the
date of the said requested Advance, accept a Bankers' Acceptance (or in the case
of a Non-BA Lender, make a BA Equivalent Note Loan) in an amount equal to its
Proportionate Share of the requested Advance. Each Advance requested by the
Borrower by way of Bankers' Acceptances shall be in an amount such that each
said Lender will issue a Bankers' Acceptance (or issue a BA Equivalent Note) in
a multiple of $100,000.00. The Borrower agrees to deliver in favour of each
Lender such other agreements and documentation as such Lender may reasonably
require (not inconsistent with this Agreement) in respect of such Lender's
requirements for the acceptance of Bankers' Acceptances or the issuance of BA
Equivalent Notes.

      (d) All payments of principal (including voluntary and mandatory
Repayments), interest and other amounts by the Borrower to the Agent in respect
of the Outstanding Advances under a Credit Facility shall be paid by the Agent
to the Lenders in accordance with their respective Proportionate Shares of the
Outstanding Advances under such
<PAGE>
                                      -37-

Credit Facility; except that stamping fees in respect of Bankers' Acceptances
and BA Equivalent Notes shall be remitted by the Agent to the respective Lenders
who issued or accepted such Bankers' Acceptances and BA Equivalent Notes. For
greater certainty, the Proportionate Share of each Facility B Lender in respect
of Advances and Repayments under Facility B shall be determined with respect to
the aggregate amount of the Outstanding Advances under Facility B and not the
Outstanding Advances under any Tranche thereof; and similarly all Rollovers and
Conversions under Facility B shall be based on the aggregate amount of the
Outstanding Advances under Facility B and not the Outstanding Advances under any
Tranche thereof.

      (e) Any Prepayment under this Agreement (whether or not voluntarily made
by the Borrower) shall be applied against the Borrower's obligations to make
Repayments under paragraphs 3.04(b), (c) and (d) in reverse chronological order.

5.04 PLACE OF ADVANCES, REPAYMENTS

      (a) All payments of principal, interest and other amounts to be made by
the Borrower pursuant to this Agreement (other than payments in respect of
Service Agreements, which are payable directly to BMO) shall be made to the
Agent's address noted in section 13.06 or to such other address as the Agent may
direct in writing from time to time. All payments received by the Agent on a
Business Day before 2:00 p.m. (Toronto time) shall be treated as having been
received by the Agent on that day; payments made after such time on a Business
Day shall be treated as having been received by the Agent on the next Business
Day.

      (b) Whenever any payment shall be due on a day which is not a Business
Day, the date for payment thereof shall be extended to the next succeeding
Business Day.

5.05 EVIDENCE OF OBLIGATIONS (NOTELESS ADVANCES)

      The Agent may, but shall not be obliged to, request the Borrower to
execute and deliver from time to time such promissory notes as may be required
in order to evidence its obligations to the respective Lenders under this
Agreement. Each Lender shall open and maintain, in accordance with its usual
practice, an account or accounts evidencing the Borrower' obligations to it
hereunder, and the information entered in such accounts shall be deemed to be
prima facie correct.

5.06 DETERMINATION OF EQUIVALENT AMOUNTS

      Whenever it is necessary or desirable at any time to determine the
Equivalent Amount in Canadian Dollars of an amount expressed in U.S. Dollars, or
vice-versa (specifically including for greater certainty the determination of
whether the Outstanding Advances under any Credit Facility exceed the limit
applicable to such Credit Facility and determining each Lender's Proportionate
Share of any Repayment on any date), the Equivalent Amount shall be determined
by reference to the Exchange Rate on the date of such determination.

5.07 MATURITY OF BANKERS' ACCEPTANCES AND BA EQUIVALENT NOTES; COMMITMENT TO
     PURCHASE

      (a) Each Bankers' Acceptance and each BA Equivalent Note shall have a
maturity of 30, 60, 90 or 180 days.

      (b) Each BA Lender which is a bank listed in Schedule I of the Bank Act
(Canada) agrees to purchase its own Bankers' Acceptances upon the issuance
thereof at a discount from the face amount thereof calculated at the CDOR Rate
for the relevant period in effect on the issuance date thereof.

      (c) Each BA Lender which is a bank listed in Schedule II or Schedule III
of the Bank Act (Canada) agrees to purchase its own Bankers' Acceptances upon
the issuance thereof at a discount from the face amount thereof calculated using
a rate not in excess of the CDOR Rate for the relevant period in effect on the
issuance date thereof plus up to one-tenth of one percent (0.10%).

      (d) Each Non-BA Lender agrees to purchase BA Equivalent Notes issued by it
hereunder at a discount from the face amount thereof calculated using a rate not
in excess of the CDOR Rate for the relevant period in effect on the issuance
date thereof.

5.08 SPECIAL PROVISIONS REGARDING BANKERS' ACCEPTANCES

      The following provisions are applicable to Bankers' Acceptances issued by
the Borrower and accepted by any BA Lender hereunder:

Payment of Bankers' Acceptances

      (a) The Borrower agrees to provide for each Bankers' Acceptance by payment
of the face amount thereof to the Agent on behalf of the BA Lender on the
maturity of the Bankers' Acceptance or, prior to such maturity, on the
Acceleration Date; and the Agent shall remit the said amount to such BA Lender
and such BA Lender shall in turn remit such amount to the holder of the Bankers'
Acceptance. If the Borrower fails to provide for the payment of the Bankers'
Acceptance accordingly, any amount not so paid shall be immediately payable by
the Borrower to the Agent on behalf of the BA Lender together with interest on
such amount calculated daily and payable monthly at the rate and in the manner
applicable to Canadian Dollar Loans under the Credit Facility under which such
Bankers' Acceptance was issued. The Borrower agrees not to claim any days of
grace for the payment at maturity of any Bankers' Acceptance and agrees to
indemnify and save harmless the BA Lender in connection with all payments made
by the BA Lender (or by the Agent on its behalf) pursuant to Bankers'
Acceptances accepted by the BA Lender, together with all reasonable costs and
expenses incurred by the BA Lender in this regard. The Borrower hereby waives
any defences to payment which might otherwise exist if for any reason a Bankers'
Acceptance is held by the BA Lender for its own account at maturity.

Availability of Bankers' Acceptances
<PAGE>
                                      -39-

      (b) If at any time and from time to time the BA Lender determines, acting
reasonably, that there no longer exists a market for Bankers' Acceptances for
the term requested by the Borrower, or at all, the BA Lender shall provide
written notice thereof to the Agent and the other Lenders (which notice shall
include the basis for such determination in reasonable detail, to the extent
known to the BA Lender), and the Agent shall promptly forward such written
notice to the Borrower. In such event: (i) the BA Lender shall not be obliged to
accept Bankers' Acceptances; (ii) the other Lenders may, but shall not be
obliged to issue Bankers' Acceptances or BA Equivalent Notes (as the case may
be) if requested to do so by the Borrower (the Borrower reserving its rights to
receive Advances under other Availment Options as provided herein); and (iii) if
the other Lenders decide to issue Bankers' Acceptances and BA Equivalent Notes,
the said BA Lender shall make a Canadian Dollar Loan in the amount of the
Bankers Acceptance it would have otherwise been required to issue; provided
that, the said BA Lender's obligations to accept Bankers' Acceptances shall be
reinstated immediately upon the Agent notifying the Borrower that the applicable
market for Bankers' Acceptances exists again.

Power of Attorney

      (c) The Borrower hereby appoints each BA Lender which issues Bankers'
Acceptances hereunder as its true and lawful attorney to complete and issue
Bankers' Acceptances on behalf of the Borrower in accordance with written,
verbal or facsimile transmitted instructions provided by the Borrower's
authorized signing officers to the Agent on behalf of such BA Lender. The
Borrower hereby ratifies all that its said attorney may do by virtue hereof. In
the event the Borrower shall deliver verbal or facsimile transmitted
instructions to the Agent in accordance with this Agreement, the Borrower
acknowledges that such instructions acted upon by the Agent and any BA Lender
will, in the absence of negligence or wilful misconduct, be conclusively deemed
to be valid instructions, whether or not authorized by the Borrower or whether
or not accurately transmitted. The Borrower agrees to indemnify and hold
harmless the Agent and the BA Lenders and their respective directors, officers
and employees from and against any charges, complaints, costs, damages,
expenses, losses or liabilities of any kind or nature which they may incur,
sustain or suffer, arising from or by reason of acting, or failing to act, as
the case may be, on any such verbal or facsimile transmitted instructions or on
this power of attorney, except to the extent caused by the negligence or wilful
misconduct of the Agent or any BA Lender. The Borrower hereby agrees that each
Bankers' Acceptance completed and issued and accepted in accordance with this
section 5.08 by any Vice-President or Senior Manager of any BA Lender (or any
other employee of such BA Lender designated by any such officer as his or her
substitute) on behalf of the Borrower is a valid, binding and negotiable
instrument of the Borrower as drawer and endorser. The Borrower agrees that each
BA Lender's accounts and records will constitute prima facie evidence of the
execution and delivery by the Borrower of Bankers' Acceptances. This power of
attorney shall continue in force until written notice of revocation has been
served upon the Agent by the Borrower at the Agent's address set out in section
13.06.

                                      -40-

5.09 SPECIAL PROVISIONS REGARDING BA EQUIVALENT NOTES

      Each Non-BA Lender will not accept Bankers' Acceptances hereunder, and
shall instead from time to time make BA Equivalent Note Loans to the Borrower.
Each BA Equivalent Note Loan shall be evidenced by a non-interest bearing
promissory note payable by the Borrower to the Non-BA Lender substantially in
the form of Schedule "H" attached hereto, which will be purchased by the Non-BA
Lender. Each BA Equivalent Note shall be negotiable by the Non-BA Lender without
notice to or the consent of the Borrower, and the holder thereof shall be
entitled to enforce such BA Equivalent Note against the Borrower free of any
equities, defences or rights of set-off that may exist between the Borrower and
the Non-BA Lender. In this Agreement, all references to a BA Equivalent Note
shall mean the loan evidenced thereby if required by the context; and all
references to the "issuance" of a BA Equivalent Note by a Non-BA Lender and
similar expressions shall mean the making of a BA Equivalent Note Loan by the
Non-BA Lender to the Borrower evidenced by a BA Equivalent Note. The following
provisions are applicable to each BA Equivalent Note Loan made by a Non-BA
Lender to the Borrower hereunder:

Payment of BA Equivalent Notes

      (a) The Borrower agrees to provide for each BA Equivalent Note by payment
of the face amount thereof to the Agent on behalf of the Non-BA Lender on the
maturity of the BA Equivalent Note or, prior to such maturity, on the
Acceleration Date; and the Agent shall remit the said amount to such Non-BA
Lender and such Non-BA Lender shall in turn remit such amount to the holder of
the BA Equivalent Note. If the Borrower fails to provide for the payment of the
BA Equivalent Note accordingly, any amount not so paid shall be immediately
payable by the Borrower to the Agent on behalf of the Non-BA Lender together
with interest on such amount calculated daily and payable monthly at the rate
and in the manner applicable to Canadian Dollar Loans under the Credit Facility
under which such BA Equivalent Note was issued. The Borrower agrees not to claim
any days of grace for the payment at maturity of any BA Equivalent Note and
agrees to indemnify and save harmless the Non-BA Lender in connection with all
payments made by the Non-BA Lender (or by the Agent on its behalf) pursuant to
BA Equivalent Notes accepted by the Non-BA Lender, together with all reasonable
costs and expenses incurred by the Non-BA Lender in this regard. The Borrower
hereby waives any defences to payment which might otherwise exist if for any
reason a BA Equivalent Note is held by the Non-BA Lender for its own account at
maturity.

Availability of BA Equivalent Notes

      (b) If at any time and from time to time the Non-BA Lender determines,
acting reasonably, that there no longer exists a market for the sale of BA
Equivalent Notes for the term requested by the Borrower, or at all, the Non-BA
Lender shall provide written notice thereof to the Agent and the other Lenders
(which notice shall include the basis for such determination in reasonable
detail, to the extent known to the Non-BA Lender), and the Agent shall promptly
forward such written notice to the Borrower. In such event: (i) the Non-BA
Lender shall not be obliged to make BA Equivalent Note Loans to the
<PAGE>
                                      -41-

Borrower; (ii) the other Lenders may, but shall not be obliged to issue Bankers'
Acceptances or BA Equivalent Notes (as the case may be) if requested to do so by
the Borrower (the Borrower reserving its rights to receive Advances under other
Availment Options as provided herein); and (iii) if the other Lenders decide to
issue Bankers' Acceptances and BA Equivalent Notes, the Non-BA Lender shall make
a Canadian Dollar Loan in the amount of the BA Equivalent Note it would have
otherwise been required to issue; provided that, the said Non-BA Lender's
obligations to make BA Equivalent Note Loans to the Borrower shall be reinstated
immediately upon the Agent notifying the Borrower that the applicable market for
the sale of BA Equivalent Notes exists again.

Power of Attorney

      (c) The Borrower hereby appoints the Non-BA Lender as its true and lawful
attorney to complete BA Equivalent Notes on behalf of the Borrower in accordance
with written, verbal or facsimile transmitted instructions delivered by the
Borrower to the Agent by the Borrower's authorized signing officers. The
Borrower hereby ratifies all that its said attorney may do by virtue hereof. In
the event the Borrower shall deliver verbal or facsimile transmitted
instructions to the Agent in accordance with this Agreement the Borrower
acknowledges that such instructions acted upon by the Agent and the Non-BA
Lender will, in the absence of negligence or wilful misconduct, be conclusively
deemed to be valid instructions, whether or not authorized by the Borrower or
whether or not accurately transmitted. The Borrower agrees to indemnify and hold
harmless the Agent and the Non-BA Lender, its directors, officers and employees
from and against any charges, complaints, costs, damages, expenses, losses or
liabilities of any kind or nature which the Agent and the Non-BA Lender, and
their respective directors, officers or employees may incur, sustain or suffer,
arising from or by reason of the Agent or the Non-BA Lender, or their respective
directors, officers or employees acting, or failing to act, as the case may be,
on any verbal or facsimile transmitted instructions or on this power of attorney
except to the extent caused by the negligence or wilful misconduct of the Agent
or any Non-BA Lender. The Borrower hereby agrees that each BA Equivalent Note
completed by any Vice-President or Senior Manager of the Non-BA Lender (or any
other employee of the Non-BA Lender designated by any such officer as his or her
substitute) on behalf of the Borrower is a valid, binding and negotiable
instrument of the Borrower as drawer and endorser. The Borrower agrees that the
Non-BA Lender's accounts and records will constitute prima facie evidence of the
execution and delivery by the Borrower of BA Equivalent Notes. This power of
attorney shall continue in force until written notice of revocation has been
served upon the Non-BA Lender by the Borrower at the Non-BA Lender's address
provided in section 13.06.

5.10 SPECIAL PROVISIONS REGARDING LIBOR LOANS

      The following provisions are applicable to LIBOR Loans made by any Lender
to the Borrower:

Drawdown Procedures
<PAGE>
                                      -42-

      (a) Upon receipt by the Agent from the Borrower of a Drawdown Request,
Conversion Notice or Rollover Notice in respect of a LIBOR Loan, the Agent will
forthwith advise the Borrower of the LIBO Rate, such rate to be determined as at
approximately 11:00 a.m. Toronto time, two (2) LIBOR Business Days before the
commencement of the LIBOR Period for such LIBOR Loan. If the Agent determines
that Eurodollar deposits for the relevant amount and LIBOR Period requested by
the Borrower are not being or will not be offered to the Agent in the LIBOR
Market or if for any other reason the Agent is unable to determine the
applicable LIBO Rate or if for any reason the LIBOR Period requested by the
Borrower is not reasonably available to the Agent, then the Agent shall notify
the Borrower of the foregoing and the Lenders shall not be obliged to make the
requested LIBOR Loan; and if such determination takes place after the Lenders
have already made Advances in the expectation that such Advances will constitute
a LIBOR Loan for the LIBOR Period requested, the Agent may by written notice to
the Borrower require the Borrower to select another LIBOR Period or convert the
said LIBOR Loan into a U.S. Dollar Loan.

Interest Payment Dates

      (b) Interest in respect of any LIBOR Loan shall be calculated on the basis
of a year of 360 days. Interest in respect of any LIBOR Loan with a LIBOR Period
of between 30 and 90 days (inclusive) shall be payable at the time the principal
amount of such LIBOR Loan is payable. Interest in respect of any LIBOR Loan with
a LIBOR Period longer than 90 days shall be payable in arrears every 90 days
commencing on the 90th day following the commencement of such LIBOR Period, and
also at the time the principal amount of such LIBOR Loan is payable.

Laws Applicable to LIBOR Loans

      (c) The Borrower acknowledges that the ability of the Lenders to maintain
or provide any LIBOR Loan and/or to charge interest on any LIBOR Loan at a LIBO
Rate is and will be subject to any statute, law, regulation, rule or direction
by any Governmental Authority having jurisdiction which may prohibit or restrict
or limit such loans and/or such interest. The Borrower agrees that the Lenders
shall have the right to comply with any such requirements and, if the Agent
acting reasonably determines it to be necessary as a result of such requirement
and provides at least ten (10) Business Days' written notice to the Borrower
which sets out in reasonable detail the basis of its determination, the Agent
may convert any LIBOR Loan to a U.S. Dollar Loan or require immediate repayment
of all LIBOR Loans, including accrued interest thereon and all applicable
breakage costs pursuant to section 5.12; provided that, the Agent's right to so
convert LIBOR Loans or require immediate repayment of LIBOR Loans shall be
immediately terminated upon the Agent notifying the Borrower that the condition
causing such prohibition, restriction or limit no longer exists.

5.11 WITHHOLDING TAX GROSS-UP

      Except as otherwise required by law, each payment by the Borrower to the
Lenders hereunder shall be made without withholding for or on account of any
present or
<PAGE>
                                      -43-

future taxes imposed by or within the jurisdiction in which the Borrower is
domiciled, any jurisdiction from which the Borrower makes any payment or any
other jurisdiction, or (in each case) any political subdivision or taxing
authority thereof or therein (other than taxes in respect of the net income,
assets or capital of any Lender). If any such withholding is required by law,
the Borrower shall make the withholding, pay the amount withheld to the
appropriate Governmental Authority before penalties attach thereto or interest
accrues thereon and forthwith pay to the Lenders such additional amount as may
be necessary to ensure that the net amount actually received by them (after
payment of such taxes including any taxes on such additional amount paid) is
equal to the amount which they would have received if no amounts had been
withheld.

5.12 INDEMNITY RE SERVICE AGREEMENTS

      In respect of any Service Agreement which may be entered into between BMO
and a Company other than the Borrower, the Borrower hereby agrees to indemnify
BMO against any and all liabilities, obligations, losses, damages, penalties,
costs, expenses or disbursements of any kind or nature whatsoever that may be
imposed on or incurred by BMO arising from or in connection with any failure by
such Company to observe and perform all of its obligations thereunder. The said
obligation of the Borrower to indemnify BMO shall comprise part of the
Obligations hereunder.

5.13 BREAKAGE COSTS

      If any Advance made by a Lender in the form of a Bankers' Acceptance,
LIBOR Loan or Fixed-Rate Term Loan is repaid or converted prior to the scheduled
maturity date thereof (whether as a result of Prepayment, acceleration or
otherwise), the Borrower agrees to pay to the Agent upon demand all losses,
damages, costs and expenses which such Lender has incurred or may incur as a
result of such Repayment or Conversion prior to the said scheduled maturity
date, as determined by such Lender in accordance with its usual practice;
provided that the Agent shall provide the Borrower with a written certificate
showing in reasonable detail the basis for such claim, which certificate shall
be deemed to be correct absent manifest error.

specified payment date within three (3) Business Days' after such specified
payment date;

      (b) the Borrower fails to pay any amount, other than an amount referred to
in paragraph (a) above, payable by the Borrower under this Agreement, the
Security, any Service Agreement or any other agreement made between it and any

      (e) Holdings or any Company defaults under one or more agreements or
instruments relating to its Funded Debt (other than the Obligations) or permits
any other event to occur and to continue without being waived or cured after any

acceleration actually occurs) or Holdings or any Company fails to pay any Funded
Debt (other than the Obligations) in an aggregate principal amount of $250,000

unless (i) Holdings or such Company (as the case may be) is diligently defending
such proceeding in good faith and on reasonable grounds as determined by the
Agent and the Lenders acting reasonably, and (ii) such proceeding does not in
the reasonable opinion of the Agent and the Lenders materially adversely affect

contested by Holdings or such Company in good faith and on reasonable grounds as
determined by the Agent and the Lenders acting reasonably, and (ii) such

by the holders of the 12 3/8% senior secured notes of Sterling Chemicals, Inc.

on May 14, 2002 shall not constitute an Event of Default pursuant to this
paragraph (i);

      (j) any Person takes possession of any property of Holdings or any Company
that is material to its financial condition, business or operations by way of or
in contemplation of enforcement of security, or a distress or execution or

further liability or obligation thereunder; or any document (other than a
Guarantee) constituting part of the Security shall for any reason fail to create

such Company diligently attempts to remedy such failure and diligently informs
the Agent of its efforts in this regard, and the failure is remedied within such
thirty (30) day period, then the failure shall not constitute an Event of

      (m) any Governmental Authority shall take any action or proceeding to

material to its financial condition, business or operations;

      (n) a change occurs which in the reasonable opinion of the Lenders

delayed;
<PAGE>
                                      -71-

provided that the Lenders hereby consent to the acquisition of Control of the
Borrower by the holders of the 12 3/8% senior secured notes of Sterling
Chemicals, Inc. pursuant to the joint plan of reorganization filed in the
Chapter 11 Proceedings on May 14, 2002 (as such plan may be amended in any
respect which does not involve Control of the Borrower being acquired by any
other Person), provided that none of the officers or employees of the Borrower
listed in Schedule 10.01(o) is terminated or requested to resign as a result of
or in connection with such change in Control of the Borrower.

10.02 ACCELERATION UPON EVENT OF DEFAULT; ADDITIONAL INTEREST

      Upon the occurrence of an Insolvency Default, all obligations of the
Borrower to the Agent and the Lenders shall become immediately due and payable,
without the necessity of any demand upon or notice to the Borrower by the Agent.
Upon the occurrence of any Event of Default other than an Insolvency Default,
the Agent may by written notice to the Borrower declare all Obligations to be
immediately due and payable. From and during the occurrence of an Event of
Default, both before and after the Acceleration Date, all Outstanding Advances
shall bear interest at the rates otherwise applicable plus 2% per annum in order
to compensate the Lenders for the additional risk.

10.03 ACCELERATION OF CERTAIN CONTINGENT OBLIGATIONS

      Upon the occurrence of an Event of Default, any Lender which has issued a
Bankers' Acceptance, BA Equivalent Note, LIBOR Loan, Fixed-Rate Term Loan or
Letter of Credit with the Borrower or entered into a Service Agreement with a
Company may make a Canadian Dollar Loan or U.S. Dollar Loan to the Borrower in
an amount equal to the face amount of such Bankers' Acceptance, BA Equivalent
Note, LIBOR Loan, Fixed-Rate Term Loan or Letter of Credit, or such Company's
liability under such Service Agreement, as the case may be; and the proceeds of
any such Loan shall be held by such Lender and used to satisfy the Lenders'
obligations under the said Bankers' Acceptance, BA Equivalent Note, LIBOR Loan,
Fixed-Rate Term Loan, Letter of Credit or Service Agreement as such becomes due.
Any such Loan made in respect of a Bankers' Acceptance, BA Equivalent Note,
LIBOR Loan, Fixed-Rate Term Loan or Letter of Credit shall bear interest at the
rate and in the manner applicable to Canadian Dollar Loans under the Credit
Facility under which such Bankers' Acceptance, BA Equivalent Note, LIBOR Loan,
Fixed-Rate Term Loan or Letter of Credit was issued. Any such Loan made in
respect of a Service Agreement shall bear interest at the rate and in the manner
applicable to Canadian Dollar Loans under the Credit Facility which provides for
the highest interest rate at such time.

10.04 COMBINING ACCOUNTS, SET-OFF

      Upon the occurrence and during the continuation of an Event of Default, in
addition to and not in limitation of any rights now or hereafter granted under
applicable law, a Lender may without notice to any Company at any time and from
time to time:

      (a) combine, consolidate or merge any or all of the deposits or other
accounts maintained with such Lender by such Company (whether term, notice,
demand or
<PAGE>
                                      -72-

otherwise and whether matured or unmatured) and such Company's obligations to
such Lender hereunder; and

      (b) set off, apply or transfer any or all sums standing to the credit of
any such deposits or accounts in or towards the satisfaction of the said
obligations.

10.05 APPROPRIATION OF MONIES

      The Agent (subject to obtaining the unanimous consent of the Lenders in
their sole discretion) may from time to time after an Event of Default
appropriate any proceeds of realization of the Security against any portion or
portions of the Obligations, and the Borrower may not require any different
appropriation. The taking of a judgment or any other action or dealing
whatsoever by the Lenders in respect of the Security shall not operate as a
merger of any of the Obligations hereunder or in any way affect or prejudice the
rights, remedies and powers which the Lenders may have, and the foreclosure,
surrender, cancellation or any other dealing with any Security or the said
obligations shall not release or affect the liability of the Borrower or any
other Person in respect of the remaining portion of the Obligations.

10.06 NO FURTHER ADVANCES

      Upon the occurrence and during the continuation of a Default, the Lenders
shall not be obliged to make any further Advances.

10.07 GARNISHMENT AND NOTICE OF STATUTORY LIENS

      If any Lender receives a garnishment notice, notice or claim in respect of
a Statutory Lien or a demand for payment or other notice of similar effect by an
applicable Governmental Authority in respect of Holdings or any Company, then
unless and until such notice is withdrawn in writing, the Lenders shall not be
obliged to provide any further Advances hereunder.

10.08 JUDGMENT CURRENCY

      If for the purposes of obtaining judgment in any court in any jurisdiction
with respect to this Agreement it becomes necessary for a Lender to convert into
the currency of such jurisdiction (in this section called the "Judgment
Currency") any amount due to the Lender by the Borrower hereunder in any
currency other than the Judgment Currency, then conversion shall be made at the
Exchange Rate prevailing on the Business Day before the day on which judgment is
given. In the event that there is a change in the Exchange Rate prevailing
between the Business Day before the day on which the judgment is given and the
date of payment of the amount due, the Borrower will, on the date of payment,
pay such additional amounts (if any) or be entitled to receive reimbursement of
such amount, if any, as may be necessary to ensure that the amount paid on such
date is the amount in the Judgment Currency which when converted at the Exchange
Rate prevailing on the date of payment is the amount then due under this
Agreement in such other currency. Any additional amount due by the Borrower
under
<PAGE>
                                      -73-

this section will be due as a separate debt and shall not be affected by
judgment being obtained for any other sums due under or in respect of this
Agreement.

10.09 REMEDIES CUMULATIVE

      All of the rights and remedies granted to the Lenders in this Agreement,
and any other documents or instruments in existence between the parties or
contemplated hereby, and any other rights and remedies available to the Lenders
at law or in equity, shall be cumulative. The exercise or failure to exercise
any of the said remedies shall not constitute a waiver or release thereof or of
any other right or remedy, and shall be non-exclusive.

10.10 PERFORMANCE OF COVENANTS BY AGENT

      If the Borrower fails to perform any covenant or obligation to be
performed by it pursuant to this Agreement, the Agent may in its sole discretion
perform any of the said obligations but shall be under no obligation to do so;
and any amounts expended or advanced by the Agent for such purpose shall be
payable by the Borrower upon demand together with interest at the highest rate
then applicable to the Credit Facilities.

10.11 INSOLVENCY PROCEEDINGS

      If Holdings or any Company intends to take the benefit of any Insolvency
Legislation, including making an assignment for the general benefit of
creditors, making a proposal or filing a notice of intention to make a proposal
under Insolvency Legislation, the Borrower covenants and agrees to provide the
Agent with five Business Days' prior written notice before any of the
aforementioned proceedings are commenced. As soon as possible prior to the
commencement of any such proceedings, the Borrower shall provide to the Agent
copies of all relevant filing materials, including copies of draft court orders,
plans of compromise, proposals and notices of intention. During this notice
period the Agent may, in its sole discretion, elect to exercise any and all
rights and remedies which may be available to it at that time as set out in this
Agreement.

      "COLLATERAL" means all property, assets and undertaking of the Companies
      encumbered by the Security, all Guarantees contemplated by the Security,
      and all property, assets and undertaking encumbered by the Security in
      support of such Guarantees; together with all proceeds of the foregoing;;

      "DOCUMENTS" means this Agreement, the Security and any other documents,
      agreements or certificates delivered or contemplated to be delivered
      pursuant to or in connection with any of the foregoing; and "DOCUMENT"
      means any one of the foregoing;

      which in the aggregate have issued Commitments hereunder representing

      "PROCEEDS OF REALIZATION", in respect of the Security or any portion
      thereof, means all amounts received by the Agent and any Lender in

            (a)   any realization thereof, whether occurring as a result of
                  enforcement or otherwise;

            (b)   any sale, expropriation, loss or damage or other disposition
                  of the Collateral or any portion thereof; or

            (c)   the dissolution, liquidation, bankruptcy or winding-up of the
                  Borrower or any of its Subsidiaries which has provided

                  creditors;

      and all other amounts which are expressly deemed to constitute "Proceeds
      of Realization" in this Agreement.

11.02 FAILURE OF LENDER TO FUND

      Unless the Agent has actual knowledge that a Lender has not made or will
not make available to the Agent for value on the date requested for an Advance
by the Borrower under a Credit Facility (a "Drawdown Date") such Lender's
Proportionate
<PAGE>
                                      -75-

Share of such Advance requested, the Agent shall be entitled to assume that such
amount has been or will be received from such Lender when so due and the Agent
may (but shall not be obliged to), in reliance upon such assumption, make
available to the Borrower a corresponding amount. If such amount is not in fact
received by the Agent from such Lender on such Drawdown Date and the Agent has
made available a corresponding amount to the Borrower on such Drawdown Date as
aforesaid, such Lender shall pay to the Agent on demand an amount equal to the
product of (i) the interest rate per annum applicable to the Advance multiplied
by (ii) the amount that should have been paid to the Agent by such Lender on
such Drawdown Date and was not, multiplied by (iii) a fraction, the numerator of
which is the number of days that have elapsed from and including such Drawdown
Date to but excluding the date on which the amount is received by the Agent from
such Lender and the denominator of which is 365. A certificate of the Agent
containing details of the amount owing by a Lender under this section shall be
deemed to be prima facie correct. If any such amount is not in fact received by
the Agent from such Lender on such Drawdown Date , the Agent shall be entitled
to recover from the Borrower, on demand, the related amount made available by
the Agent to the Borrower as aforesaid together with interest thereon at the
applicable rate per annum payable by the Borrower hereunder (but for greater
certainty, without prejudice to any claim which the Borrower might have against
such Lender as a result of such Lender not having made its Proportionate Share
of such Advance).

11.03 PAYMENTS BY AGENT

      (a) The following provisions shall apply to any and all payments made by
the Agent to the Lenders hereunder:

      (i)   the Agent shall be under no obligation to make any payment (whether
            in respect of principal, interest, fees or otherwise) to any Lender
            until an amount in respect of such payment has been received by the
            Agent from the Borrower;

      (ii)  if the Agent receives a payment of principal, interest, fees or
            other amount owing by the Borrower under a Credit Facility which is
            less than the full amount of any such payment due, the Agent shall
            have no obligation to remit to each Lender any amount other than
            such Lender's Proportionate Share of the amount actually received by
            the Agent;

      (iii) if any Lender has advanced more or less than its Proportionate Share
            of its Commitment under a Credit Facility, such Lender's entitlement
            to such payment shall be increased or reduced, as the case may be,
            in proportion to the amount actually advanced by such Lender;

      (iv)  if a Lender's Proportionate Share of an Advance under a Credit
            Facility has been advanced for less than the full period to which
            any payment by the Borrower relates, such Lender's entitlement to
            receive a portion of any payment of interest or fees shall be
            reduced in proportion to the length of time such Lender's
            Proportionate Share has actually been outstanding
<PAGE>
                                      -76-

             (unless such Lender has paid all interest required to have been
             paid by it to the Agent pursuant to section 11.02);

      (v)    the Agent acting reasonably and in good faith shall, after
             consultation with the Lenders in the case of any dispute, determine
             in all cases the amount of all payments to which each Lender is
             entitled and such determination shall be deemed to be prima facie
             correct;

      (vi)   upon request, the Agent shall deliver a statement detailing any of
             the payments to the Lenders referred to herein;

      (vii)  all payments by the Agent to a Lender hereunder shall be made to
             such Lender at its address set out herein unless notice to the
             contrary is received by the Agent from such Lender; and

      (viii) if the Agent has received a payment from the Borrower on a Business
             Day (not later than the time required for the receipt of such
             payment as set out in this Agreement) and fails to remit such
             payment to any Lender entitled to receive its Proportionate Share
             of such payment on such Business Day, the Agent agrees to pay
             interest on such late payment at the same rate and in the same
             manner as set out in section 11.02.

      (b) Unless the Agent has actual knowledge that the Borrower has not made
or will not make a payment to the Agent in respect of a Credit Facility for
value on the date in respect of which the Borrower has notified the Agent in
writing that the payment will be made, the Agent shall be entitled to assume
that such payment has been or will be received from the Borrower when due and
the Agent may (but shall not be obliged to), in reliance upon such assumption,
pay to each Lender its Proportionate Share of the payment expected from the
Borrower. If the Agent has made such payments to the Lenders and the expected
payment from the Borrower is in fact not received by the Agent on the required
date, then each Lender which has received any such payment agrees to refund such
payment to the Agent immediately upon request, and the Borrower shall, without
limiting its other obligations under this Agreement, indemnify the Agent against
any and all liabilities, obligations, losses (other than loss of profit),
damages, penalties, costs, expenses or disbursements of any kind or nature
whatsoever that may be imposed on or incurred by the Agent as a result of having
made such payments to the Lenders, except for those arising from the Agent's
negligence or wilful misconduct. A certificate of the Agent with respect to any
amount owing by the Borrower under this section shall be deemed to be prima
facie correct.

      (c) The Borrower hereby irrevocably authorizes the Agent to debit any
account maintained by the Borrower with the Agent in order to make payments to
the Lenders as contemplated herein. The Agent agrees to provide written notice
to the Borrower of each such debit in reasonable detail. The Borrower shall be
deemed to have agreed to each such debit unless the Borrower objects in writing
to such debit within thirty (30) days after receipt of such written notice from
the Agent.

            Agent may from time to time without notice to or the consent of the
            Lenders execute and deliver partial releases of the Security from
            time to time in respect of any item of Collateral to the extent
            expressly permitted in this Agreement, whether or not the Borrower
            may have an obligation to apply the net proceeds thereof as a
            Repayment.

      (e) Except for the matters described in paragraphs (c) and (d) above, any
action to be taken or decision to be made by the Lenders pursuant to the Credit
Agreement (specifically including for greater certainty the issuance of a demand
for payment of the Obligations or the provision of any waiver in respect of a
breach of any covenant, other than a breach of the covenants contained in
clauses 7.02(e)(i) and 7.02(g)(ii)) shall be effective if approved by a Majority
of the Lenders pursuant to paragraph 11.09(j); and any such decision or action
shall be final and binding upon all the Lenders.

11.05 SECURITY HELD BY AGENT

      Except to the extent provided in section 11.06, the Security shall be
granted in favour of and held by the Agent for and on behalf of the Lenders in
accordance with the provisions of this Agreement. The Agent shall, in accordance
with its usual practices in effect from time to time, take all steps required to
perfect and maintain such Security, including: taking possession of the share
certificates representing the shares required to be pledged hereunder; filing
renewals and change notices in respect of such Security; and ensuring that the
name of the Agent is noted as loss payee or mortgagee on all property insurance
policies covering assets subject to the Security. If the Agent becomes aware of
any matter concerning the Security which it considers to be material, it shall
promptly inform the Lenders. The Agent shall comply with all instructions
provided by the Lenders in connection with the enforcement or release of the
Security which it holds. The Agent agrees to permit each Lender to review and
make photocopies of the original documents comprising the Security from time to
time upon reasonable notice. Each of the Lenders acknowledges that to the extent
permitted by applicable law, the Security and the remedies provided under the
Documents to the Lenders are for the benefit of the Lenders collectively and
acting together and not severally, and further acknowledges that its rights
hereunder and under the Security are to be exercised not severally, but by the
Agent upon the decision of the Majority of the Lenders. Accordingly,
notwithstanding any of the provisions contained herein or in the Security each
Lender covenants and agrees that it shall not be entitled to take any action
hereunder or thereunder including, without limitation, any declaration of
default hereunder or thereunder but that any such action shall be taken only by
the Agent with the prior written agreement of the Majority of the Lenders.

11.06 PRIORITIES OF SECURITY

      Notwithstanding any other provision of this Agreement, the Proceeds of
Realization of the Security or any portion thereof shall be distributed in the
following order:

      (i)   firstly, in payment of all reasonable costs and expenses incurred by
            the Agent and the Lenders in connection with such realization,
            including legal, accounting and receivers' fees and disbursements;

      (ii)  secondly, against the Obligations, each Lender being entitled to
            receive a portion of such Proceeds of Realization determined by
            reference to the amount of the Obligations due to such Lender
            divided by the aggregate amount of the Obligations due to all
            Lenders; and

      (iii) thirdly, if all obligations of the Borrower listed above have been
            paid and satisfied in full, any surplus Proceeds of Realization
            shall be paid in accordance with applicable law.

11.07 APPOINTMENT OF AGENT

      Subject to section 11.11, each Lender hereby irrevocably appoints the
Agent to act as its agent in connection with this Agreement, and irrevocably
authorizes the Agent to exercise such rights, powers and discretions as are
delegated to it pursuant to this Agreement together with all such rights, powers
and discretions as are incidental hereto or thereto. The Agent hereby accepts
such appointment and agrees to be bound by the provisions of this Agreement for
so long as it is an Agent hereunder. The Agent shall have only those duties and
responsibilities which are expressly specified in this Agreement, and it may
perform such duties by or through its agent or employees. It is expressly agreed
that the Agent is not a fiduciary of any Lender nor shall it owe any fiduciary
duties to any Lender. Any Person to whom the Agent may delegate duties or
responsibilities as permitted hereunder shall enjoy and be bound by the same
benefits, rights, protections and obligations as those provided to the Agent or
to which the Agent is subject under this Agreement, mutatis mutandis.

11.08 PROTECTION OF AGENT

      (a) Unless and until instructed by a Majority of the Lenders, the Agent
shall not be bound to inquire as to:

      (i)   whether any representation made by the Borrower in or in connection
            with any Document is true;

      (ii)  the occurrence or otherwise of any Event of Default or Default;

      (iii) the performance by the Borrower of its obligations under any
            Document;
<PAGE>
                                      -80-

      (iv)  any breach of or default by the Borrower or any Related Person under
            its obligations under any Document; or

      (v)   the use or application by the Borrower of any of the proceeds of the
            Credit Facilities.

      The Agent shall report the results of any such enquiry to the Lenders, but
shall have no obligation to take any action in connection therewith unless
otherwise instructed by a Majority of the Lenders as provided herein.

      (b) Unless the Agent has actual knowledge or actual notice to the
contrary, it may assume that:

      (i)   any representation made by any Company in or in connection with any
            Document is true;

      (ii)  no Event of Default or Default has occurred; and

      (iii) the Borrower is not in breach of or in default under, its
            obligations under any Document.

      (c) Unless the Agent has actual knowledge or actual notice to the
contrary, it may assume that each Lender's address is that set out herein until
it has received from such Lender a notice designating some other office of such
Lender as its address and act upon any such notice until the same is superseded
by a further such notice.

      (d) The Agent may engage and pay for the advice or services of any
lawyers, accountants or other experts whose advice or services may to it seem
necessary, expedient or desirable and rely upon any advice so obtained.

      (e) Unless the Agent has actual knowledge or actual notice to the
contrary, the Agent may rely as to matters of fact which might reasonably be
expected to be within the knowledge of any Company upon a statement contained in
any Document.

      (f) Unless the Agent has actual knowledge or actual notice to the
contrary, the Agent may rely upon any communication or document believed by it
to be genuine.

      (g) The Agent may refrain from exercising any right, power or discretion
vested in it under this Agreement unless and until instructed by a Majority of
the Lenders as to whether or not such right, power or discretion is to be
exercised and, if it is to be exercised, as to the manner in which it should be
exercised.

      (h) The Agent may refrain from exercising any right, power or discretion
vested in it which would or might in its opinion in its sole discretion be
contrary to any law of any jurisdiction or any directive or otherwise render it
liable to any Person, and may do anything which is in its opinion in its sole
discretion necessary to comply with any such law or directive.
<PAGE>
                                      -81-

      (i) The Agent may delegate to such other Person, such duties and
responsibilities of the Agent hereunder as it shall determine to be appropriate
in respect of dealings with or relating to the Borrower or any other Person.

      (j) The Agent may refrain from acting in accordance with any instructions
of a Majority of the Lenders to begin any legal action or proceeding arising out
of or in connection with this Agreement or take any steps to enforce or realize
upon any Security, until it shall have received such security as it may
reasonably require (whether by way of payment in advance or otherwise) against
all costs, claims, expenses (including legal fees) and liabilities which it will
or may expend or incur in complying with such instruction.

      (k) The Agent shall not be bound to disclose to any Person any information
relating to the Borrower or any Related Person if such disclosure would or might
in its opinion in its sole discretion constitute a breach of any law or
regulation or be otherwise actionable at the suit of any Person.

      (l) The Agent shall not accept any responsibility for the accuracy and/or
completeness of any information supplied in connection herewith or for the
legality, validity, effectiveness, adequacy or enforceability of any Document
and the Agent shall not be under any liability to any Lender as a result of
taking or omitting to take any action in relation to any Document save in the
case of the Agent's negligence or wilful misconduct.

11.09 DUTIES OF AGENT

      The Agent shall:

            (a)   provide to each Lender copies of all financial information
                  received from the Borrower promptly after receipt thereof, and
                  copies of any Drawdown Requests, Conversion Notices, Rollover
                  Notices, Repayment Notices and other notices received by the
                  Agent from the Borrower upon request by any Lender;

            (b)   promptly advise each Lender of Advances required to be made by

                  hereunder in accordance with the terms of this Agreement;

            (c)   promptly notify each Lender of the occurrence of any Event of
                  Default or any Default by the Borrower in the due performance
                  of its obligations under this Agreement or the Security and of
                  which the Agent has actual knowledge or actual notice;

            (d)   each time the Borrower requests the prior written consent of a
                  Majority of the Lenders, use its best efforts to obtain and
                  communicate to the Borrower the response of a Majority of the
<PAGE>
                                      -82-

                  Lenders in a reasonably prompt and timely manner having due
                  regard to the nature and circumstances of the request;

            (e)   give written notice to the Borrower in respect of any other
                  matter in respect of which notice is required in accordance
                  with or pursuant to this Agreement, promptly or promptly after
                  receiving the consent of the Majority of Lenders, if required
                  under the terms of this Agreement;

            (f)   except as otherwise provided in this Agreement, act in
                  accordance with any instructions given to it by a Majority of
                  the Lenders;

            (g)   at the time of engaging any agent, receiver, receiver-manager,
                  consultant, monitor or other party in connection with the
                  Security or the enforcement thereof, obtain the agreement of
                  such party to comply with the applicable terms of this
                  Agreement in carrying out any such enforcement activities and
                  dealing with any Proceeds of Realization;

            (h)   if so instructed by a Majority of the Lenders, refrain from
                  exercising any right, power or discretion vested in it under
                  this Agreement or any document incidental thereto;

            (i)   account for any monies received by it in connection with this
                  Agreement, the Security and any other agreement delivered in
                  connection herewith or therewith; and

            (j)   call a meeting of the Lenders at any time not earlier than
                  five (5) days and not later than thirty (30) days after
                  receipt of a written request for a meeting provided by any
                  Lender; provided that the above notice requirements may be
                  waived by the unanimous agreement of the Lenders; and provided
                  further that any instrument executed by all of the Lenders
                  (which may be in counterparts) shall have the same effect as
                  if passed by the Lenders at a duly called meeting.

11.10 INDEMNIFICATION OF AGENT

      Each Lender shall on demand by the Agent indemnify the Agent in accordance
with each such Lender's Proportionate Share of all Credit Facilities, against
any and all costs, claims, reasonable expenses (including legal fees) and
liabilities which the Agent may incur (and which have not been reimbursed by the
Borrower) to the extent required hereunder, otherwise than by reason of its own
negligence or wilful misconduct, in acting in its capacity as the Agent under
this Agreement, the Security or any other Document.
<PAGE>
                                      -83-

11.11 TERMINATION OR RESIGNATION OF AGENT

      (a) A Majority of the Lenders may terminate the Agent's appointment
hereunder upon giving the Agent 90 days' prior written notice to such effect.

      (b) The Agent may resign its appointment hereunder at any time upon giving
90 days' prior written notice to each Lender, without giving any reason
therefor.

      (c) In the event of any such termination or resignation, a Majority of the
Lenders shall appoint a successor Agent acceptable to the Borrower (whose
consent may not be unreasonably withheld). Within a reasonable time after the
appointment of the successor Agent, the retiring Agent shall assign the Security
to the successor Agent. Upon such assignment the retiring Agent shall be
discharged from any further obligation hereunder but shall remain entitled to
the benefit of the provisions of this Article XI; and the Agent's successor and
each of the other parties hereto shall have the same rights and obligations
among themselves as they would have had if such successor originally had been a
party hereto as the Agent. If a Person ceases to be the Agent and a successor
Agent is not appointed within such 90 day period, upon the expiry of such period
such Person shall receive no further compensation for acting as Agent and shall
be released from all obligations as Agent except that until a successor Agent is
appointed such Person shall passively hold the Security as Agent for the Lenders
without taking any action to preserve, renew, maintain or enforce the Security;
and its sole remaining obligation shall be to assign the Security to its
successor if and when a successor Agent is appointed.

11.12 RIGHTS OF AGENT AS A LENDER

      The Agent in its capacity as a Lender shall have the same rights and
powers under the Documents as any other Lender, and it may exercise such rights
and powers as though it were not performing the duties and functions delegated
to it as the Agent hereunder. Without limiting the generality of the foregoing,
the Agent in its capacity as a Lender may retain for its own benefit any fee or
other sum receivable by it for its own account, and may accept deposits from,
lend money to, provide any advisory or other services to or engage in any kind
of banking or other business with any Company.

11.13 FINANCIAL INFORMATION

      The Agent shall have no duty or responsibility either initially or on a
continuing basis to provide any Lender with any credit or other information with
respect to the financial condition and affairs of any Company, except to the
extent expressly set out herein.

11.14 LENDERS' INDEPENDENT INVESTIGATION

      Each of the Lenders represents and warrants to the Agent and BMO that it
has made its own independent investigation of the financial condition and
affairs of the Companies in connection with the establishment of credit for the
Borrower, and that it has not relied on any information provided to it by the
Agent or BMO in connection
<PAGE>
                                      -84-

therewith, and each represents and warrants to the Agent that it shall continue
to make its own appraisal of the creditworthiness of the Companies from time to
time.

11.15 LEGAL PROCEEDINGS BY AGENT

      The Agent shall not be obligated to take any legal proceedings against the
Borrower or any other Person for the recovery of any amount due under this
Agreement or the Security, unless instructed to do so by a Majority of the
Lenders. No Lender shall bring legal proceedings against the Borrower or any
other Person hereunder under any Security or under any other Documents or in
connection herewith or therewith, or exercise any right arising hereunder or
thereunder or in connection herewith or therewith over the property and assets
of the Borrower or any other Person, without the prior written consent of a
Majority of the Lenders.

11.16 LENDERS' OBLIGATIONS SEVERAL; NO PARTNERSHIP

      The obligations of each Lender under this Agreement are several. The
failure of any Lender to carry out its obligations hereunder shall not relieve
the other Lenders of any of their respective obligations hereunder. No Lender
shall be responsible for the obligations of any other Lender hereunder. Neither
the entering into of this Agreement nor the completion of any transactions
contemplated herein shall constitute the Lenders a partnership.

11.17 SHARING OF INFORMATION

      The Agent and the Lenders may share among themselves any information they
may have from time to time concerning the Companies whether or not such
information is confidential; but shall have no obligation to do so (except for
any obligations of the Agent to provide information as required in this
Agreement).

11.18 ACKNOWLEDGEMENT BY BORROWER

      The Borrower hereby acknowledges notice of the terms of the provisions of
this Article XI and agrees to be bound hereby to the extent of its obligations
hereunder, and further agrees not make any payments, take any action or omit to
take any action which would result in the non-compliance by any Lender with its
obligations hereunder.

11.19 AMENDMENTS TO ARTICLE XI

      The Agent and the Lenders may amend any provision in this Article XI
without prior notice to or the consent of the Borrower, and the Agent shall
provide a copy of any such amendment to the Borrower reasonably promptly
thereafter; provided however if any such amendment would adversely affect any
rights, entitlements, obligations or liabilities of the Borrower (other than in
a de minimus manner), such amendment shall not be effective until the Borrower
provides its written consent thereto, such consent not to be unreasonably
withheld or arbitrarily delayed.
<PAGE>
                                      -85-

11.20 DELIVERIES, ETC.

      As between the Companies and Holdings, on the one hand, and the Agent and
the Lenders, on the other hand:

      (a) all statements, certificates, consents and other documents which the
Agent purports to deliver to a Company or to Holdings on behalf of the Lenders
shall be binding on each of the Lenders, and none of the Companies nor Holdings
shall be required to ascertain or confirm the authority of the Agent in
delivering such documents;

      (b) all certificates, statements, notices and other documents which are
delivered by a Company or Holdings to the Agent in accordance with this
Agreement shall be deemed to have been duly delivered to each of the Lenders;
and

      (c) all payments which are delivered by the Borrower to the Agent in
accordance with this Agreement shall be deemed to have been duly delivered to
each of the Lenders.

11.21 AGENCY FEE

      The Borrower agrees to pay the Agent an annual agency fee in such amount
as may be agreed in writing from time to time between the Borrower and the
Agent, payable in advance on the date of this Agreement and annually on each
anniversary date thereafter during the term of this Agreement.

                      ARTICLE XII - CHANGE IN CIRCUMSTANCES

12.01 ILLEGALITY

      If, on or after the date of this Agreement, the adoption of any applicable
law, rule or regulation, or any change in any applicable law, rule or
regulation, or any change in the interpretation or administration thereof by any
Governmental Authority charged with the interpretation or administration
thereof, or compliance by any Lender with any request or directive (whether or
not having the force of law) of any such Governmental Authority shall make it
unlawful or impossible for any Lender to make, maintain or fund its Commitment
hereunder and such Lender shall so notify the Agent, the Agent shall forthwith
give one (1) Business Days' written notice thereof to the other Lenders and the
Borrower which includes in reasonable detail the basis for its determination,
whereupon, subject to section 12.03, until such Lender notifies the Borrower and
the Agent that the circumstances giving rise to such suspension no longer exist,
the obligation of such Lender to make Advances hereunder shall be suspended.

12.02 INCREASED COST AND REDUCED RETURN

      If there is a change in or adoption of any law, regulation, order, rule,
request or directive affecting any Lender (whether or not having the force of
law but of a kind which is intended to be complied with by banks or financial
institutions generally and
<PAGE>
                                      -86-

which is being complied with by the Lender) or in the interpretation thereof by
any Governmental Authority charged with the administration thereof, and as a
result:

      (i)   the Lender incurs a cost (which it would not otherwise have
            incurred) or becomes liable to make a payment (calculated with
            reference to the amount outstanding or available under Facility A)
            with respect to continuing to provide or maintain its Proportionate
            Share of Facility A for the Borrower hereunder (other than a tax
            such as a capital or franchise tax or a tax imposed on the net
            income, assets or capital of the Lender);

      (ii)  any reserve, special deposit or similar requirement is imposed or
            increased with respect to the Outstanding Advances increasing the
            cost thereof to the Lender; or

      (iii) the Lender suffers or will suffer a reduction in the rate of return
            on its overall capital (other than a reduction by reason of any
            increase in the taxes referred to in (i) above) as a result of the
            amount of the capital that the Lender is required to maintain being
            increased or of any change in the manner in which the Lender is
            required to allocate its resources;

      then the Borrower shall, within 15 days after receipt of written notice
from the Lender (with a copy to the Agent), pay to the Lender such amount as
will compensate the Lender for and will indemnify the Lender against such
increases in cost or reductions of rate of return (to the extent not already
reflected in any other rate or fee hereunder), accruing from and after the date
of receipt of such notice.

      Each Lender will promptly notify the Borrower and the Agent of any event
of which it has knowledge, occurring after the date of this Agreement, which
will entitle such Lender to compensation pursuant to this section. A certificate
of any Lender (together with such further information as the Borrower may
reasonably request) claiming compensation under this section and setting forth
the additional amount or amounts to be paid to it hereunder shall be deemed to
be prima facie correct. In determining such amount, such Lender may use any
reasonable averaging and attribution methods. Notwithstanding the foregoing, the
Lender shall be entitled to claim compensation from the Borrower pursuant to
this section only to the extent that the Lender is also claiming compensation on
a similar basis from other borrowers (if any) for whom the Lender has
established similar credit facilities.

12.03 REPLACEMENT OF CLAIMING LENDER

      Subject to no Event of Default having occurred and continuing, if any
Lender (a "Claiming Lender") makes any demand for payment under sections 12.02,
or gives notice that the provisions of section 5.10(b), 5.11(c), 5.12 or 12.01
have or will become applicable to it, then, provided no other Lender makes any
such demand or gives such notice by the date which is 20 days after any such
demand or notice is made by a Claiming Lender, the Borrower may request that the
Claiming Lender assign in accordance with section 13.10 to one or more banks or
financial institutions to be
<PAGE>
                                      -87-

designated by the Borrower all (but not less than all) of such Lender's
Commitment and the Advances owing to it no later than 30 days following such
request by the Borrower. Such Lender shall consummate such assignment to a bank
or financial institution if such bank or financial institution (a) shall not,
upon such assignment becoming effective, make any demand for payment under
sections 12.02, or give notice that the provisions of section 5.10(b), 5.11(c),
5.12 or 12.01 have or will become applicable to it, and (b) complying with the
requirements of section 13.10; provided, however, that each such replacement
Lender shall be satisfactory to the remaining Lenders and the Agent, acting
reasonably. No such replacement of a Lender shall be considered a Repayment of
any Advance held by such Claiming Lender. The Agent and the Lenders shall have
no obligation to assist the Borrower in finding any potential lender to replace
a Claiming Lender pursuant to this section.

                             ARTICLE XIII - GENERAL

13.01 WAIVER

      The failure or delay by the Agent or any Lender in exercising any right or
privilege with respect to the non-compliance with any provisions of this
Agreement by the Borrower and any course of action on the part of the Agent or
any Lender, shall not operate as a waiver of any rights of the Agent or any
Lender unless made in writing by the Agent or such Lender. Any such waiver shall
be effective only in the specific instance and for the purpose for which it is
given and shall not constitute a waiver of any other rights and remedies of the
Agent or any Lender with respect to any other or future non-compliance.

13.02 GOVERNING LAW

      This Agreement shall be interpreted in accordance with the laws of the
Province of Ontario. Without prejudice to the right of the Agent to commence any
proceedings with respect to this Agreement in any other proper jurisdiction, the
parties hereby attorn and submit to the jurisdiction of the courts of the
Province of Ontario.

13.03 AGENT'S EXPENSES

      Whether or not the transactions contemplated by this Agreement are
completed or any Advance has been made, the Borrower agrees to pay on demand by
the Agent all expenses incurred by it or any Lender, including reasonable legal
expenses and other direct out-of-pocket expenses, in connection with this
Agreement, the Security and all documents contemplated hereby and all due
diligence, including: the preparation, administration or interpretation of such
documents, the protection and enforcement of the rights of the Agent and the
Lenders provided for thereby, the enforcement of the Security, and the
preparation of any waivers, partial discharges and similar matters which may be
required. If the Borrower has not paid any such expenses within 30 days after
the sending of a written request from the Agent, the Borrower hereby authorizes
the Agent to
<PAGE>
                                      -88-

debit the Borrower's account in order to pay any such expenses; provided that,
the Agent shall concurrently provide written notice in reasonable detail of any
such debit to the Borrower; and the debiting of such account shall not
constitute an agreement by the Borrower that such amount was owed by the
Borrower. For greater certainty, the expenses referred to in this section are in
addition to the fees and expenses referred to in any other written agreements
made among the Borrower, the Agent and the Lenders from time to time relating to
the Credit Facilities.

13.04 INDEMNITY

      In addition to any other liability of the Borrower hereunder, the Borrower
agrees to indemnify and save harmless the Agent and the Lenders from and against
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind or nature whatsoever
(collectively, "Losses") which may be imposed on, incurred by or asserted
against them which relate or arise out of or result from any failure by the
Borrower to satisfy its obligations hereunder when due or fulfil any of its
other obligations hereunder including any costs or expenses incurred by reason
of the liquidation or re-employment in whole or in part of deposits or other
funds required by the Agent or any Lender to fund or maintain the Credit
Facilities as a result of the Borrower's failure to take any required action on
the date required hereunder or specified by the Borrower in any notice given
hereunder, specifically including for greater certainty the failure of the
Borrower to satisfy any conditions precedent to be performed by it in connection
with any Advance requested hereunder after having issued a Drawdown Request
requesting such Advance, except to the extent that such Losses are caused by the
negligence or wilful misconduct of the Agent or any Lender.

13.05 INTEREST ON UNPAID COSTS AND EXPENSES

      If the Borrower fails to pay when due any amount in respect of costs or
expenses or any other amount required to be paid by it hereunder (other than
principal or interest on any Advance), it shall pay interest on such unpaid
amount from the time such amount is due until paid at the rate equal to the
highest rate of interest then applicable under the Credit Facilities.

                                      -90-

13.10 ASSIGNMENT

      (a) If an Event of Default has occurred and is continuing, any Lender may
assign all or any portion of its rights and obligations under this Agreement
from time to time to any other Person without notice to or obtaining the prior
written consent of the Borrower.

      (b) If no Event of Default has occurred and is continuing, any Lender may
assign all or any portion of its rights and obligations under this Agreement
from time to time to any assignee which is a financial institution (which term
as used in this Agreement specifically includes a bank, trust company or life
insurance company) subject to obtaining the prior written consent of the
Borrower, not to be unreasonably withheld (and for greater certainty the Lenders
acknowledge that it shall be reasonable for the Borrower to withhold its consent
to any assignment if the Borrower would thereby be required to pay additional
amounts pursuant to sections 5.10 or 12.02 hereof); provided that each
assignment is in a minimum amount of $5,000,000.

      (c) If a Lender assigns all or any portion of its rights and obligations
under this Agreement to an assignee in accordance with the provisions of this
section 13.10, and if such assignee executes and delivers to the Borrower, the
Agent and all other Lenders a written agreement to assume and be bound by all or
the assigned portion of such Lender's obligations to the Borrower and to the
other Lenders and the Agent hereunder, then immediately upon the said delivery
of such agreement the Lender's said obligations hereunder shall automatically be
released to the extent so assumed by such assignee.

      (d) Any assignment by a Lender of all or any portion of its rights and
obligations pursuant to this Agreement shall be substantially in the form of the
Assignment Agreement attached hereto as Exhibit "I".

      (e) The Borrower may not assign any of its rights or obligations under
this Agreement without the prior written consent of the Lenders and the Agent,
in their sole discretion.

      (f) The Borrower and the Lenders acknowledge that the Agent is entitled to
charge a processing and recording fee of $3,500 to any assignee in connection
with each assignment hereunder. The Borrower agrees to co-operate fully with the
Agent in connection with any assignment in compliance with this section 13.10,
and agrees to execute and deliver from time to time in favour of the Agent and
any such assignee such documents and assurances as may be reasonably required to
effect the foregoing.

      (g) Each Lender agrees that if it shall, by exercising any right of
set-off or counterclaim or otherwise, receive a payment on account of principal
or interest due to such Lender under a Credit Facility which is greater than the
proportion received by any other Lender(s) on account of principal or interest
due to such Lender(s) under such Credit Facility, the Lender receiving such
proportionately greater payment shall purchase such participations in the
Outstanding Advances held by the other Lender(s) under such Credit Facility, and
such other adjustments shall be made, as may be required so that the Outstanding
Advances under such Credit Facility shall at all times be held by the Lenders
<PAGE>
                                      -91-

in accordance with their respective Proportionate Shares under such Credit
Facility; provided that nothing in this section shall impair the right of any
Lender to exercise any right of set-off or counterclaim it may have and to apply
the amount subject to such exercise to the payment of any other indebtedness or
liability of the Borrower. The Borrower agrees, to the fullest extent it may
effectively do so under applicable law, that any holder of a participation
interest in any Outstanding Advances, whether or not acquired pursuant to the
foregoing arrangements, may exercise rights of set-off or counterclaim and other
rights with respect to such participation as fully as if such holder of a
participation were a direct creditor of the Borrower in the amount of such
participation.

13.11 ENTIRE AGREEMENT

      This Agreement and any other documents or instruments contemplated herein
or therein shall constitute the entire agreement and understanding among the
Borrower, the Lenders and the Agent relating to the subject-matter hereof.
Without limiting the foregoing, the term sheet dated April 26, 2002 between BMO
and the Borrower is superseded by this Agreement and is hereby terminated. No
provision of this Agreement, or any other document or instrument in existence
among the parties may be modified, waived or terminated except by an instrument
in writing executed by the party against whom such modification, waiver or
termination is sought to be enforced.

13.12 INCONSISTENCIES WITH SECURITY

      To the extent that there is any inconsistency between a provision of this
Agreement and a provision of any document constituting part of the Security, the
provision of this Agreement shall govern.

13.13 EXECUTION BY FAX AND COUNTERPARTS

      This Agreement may be executed in several counterparts, each of which,
when so executed, shall be deemed to be an original and which counterparts
together shall constitute one and the same Agreement. This Agreement may be
executed by facsimile, and any signature contained hereon by facsimile shall be
deemed to be equivalent to an original signature for all purposes.

13.14 BINDING EFFECT

      This Agreement shall be binding upon and shall enure to the benefit of the
parties and their respective successors and permitted assigns; "successors"
includes any corporation resulting from the amalgamation of any party with any
other corporation.

13.15 CONFIDENTIALITY

      The Agent and each Lender agree that all documentation and other
information made available by the Companies to it under or in connection with
this Agreement shall (except to the extent such documentation or other
information is publicly available or
<PAGE>
                                      -92-

hereafter becomes publicly available other than by action of the Agent or such
Lender, or was theretofore known or hereinafter becomes known to the Agent or
such Lender independently of any disclosure by the Companies) be held in
confidence by the Agent and such Lender and used solely in the evaluation,
administration and enforcement of the Advances and all matters related to this
Agreement and the Security and the transactions contemplated hereby and thereby,
and in the prosecution of defence of legal proceedings arising in connection
herewith and therewith; provided that the Agent or Lenders may disclose
documentation and information to any other Lender or any affiliates thereof.
Notwithstanding the foregoing, nothing contained herein shall be construed to
prevent the Agent or any Lender from (a) making disclosure of any information
(i) if required to do so by applicable law or regulation, (ii) to any
Governmental Authority having or claiming to have authority to regulate or
oversee any aspect of such Person's business in connection with the exercise of
such authority or claimed authority and that compels or requires such Person to
disclose such information, (iii) pursuant to any subpoena or if otherwise
compelled in connection with any litigation or administrative proceeding, (iv)
to any prospective assignee of all or any portion of a Lender's rights and
obligations hereunder provided that such prospective assignee executes and
delivers to the Borrower a confidentiality agreement in form and substance
acceptable to the Borrower, acting reasonably, or (v) to the extent that the
Agent or any Lender or its counsel deems necessary or appropriate, acting
reasonably, to effect or preserve its Security or to enforce any remedy provided
in this Agreement or the Security or otherwise available by law; or (b) making,
on a confidential basis, such disclosures as the Agent or any Lender reasonably
deems necessary or appropriate to its legal counsel, accountants or other
advisers, agents or representatives (including outside auditors). If the Agent
or any Lender is compelled to disclose such confidential information in a
proceeding requesting such disclosure or otherwise pursuant to law or
regulation, such Agent or Lender shall (i) only disclose such information as it
is compelled or otherwise legally required to disclose, and (ii) use reasonable
commercial efforts to obtain assurance from the Governmental Authority receiving
such information that it will keep such information confidential (provided that
any costs incurred by the Agent relating to such efforts shall be for the
account of the Borrower and shall comprise part of the Obligations).
