                  such Borrower;

         8.3.3    In anticipation of the maturity of Bankers' Acceptances the
                  Borrower shall do one or a combination of the following:

         (a)      deliver to the Bank prior to the maturity date and in
                  accordance with the time periods set forth in Section 2.7, a
                  Rollover Notice that the Borrower intends to draw and present
                  for acceptance on the maturity date new Bankers' Acceptances;

         (b)      deliver to the Bank a Conversion Notice pursuant to Section
                  10.1; or

         (c)      on the maturity date of the maturing Bankers' Acceptances,
                  make a payment to the Bank for the account of the Bank in an
                  amount equal to the face amount of the maturing Bankers'
                  Acceptances less the amounts dealt with under Sections
                  8.3.3(a) and 8.3.3(b).

                  If the Borrower fails so to notify the Bank or make such
                  payment, the Bank shall effect a Conversion into a Canadian
                  Prime Rate Loan as if a Conversion Notice pursuant to 8.3.3(b)
                  above had been given by the Borrower to the Bank.

         8.3.4    To facilitate the acceptance of Bankers' Acceptances as
                  aforesaid, the Borrower shall, upon execution of this
                  Agreement and from time to time as required, provide to the
                  Bank drafts drawn in blank by the Borrower upon the Bank in
                  quantities sufficient for the Bank to fulfill its obligations
                  hereunder. The Bankers' Acceptances shall be kept by the Bank
                  with like care as if the Bankers' Acceptances were the
                  property of the Bank. The Bank shall not be liable for its
                  failure to accept the Bankers' Acceptance as required
                  hereunder if the cause of such failure is, in whole or in
                  part, due to the failure of the Borrower to provide such
                  instruments to the Bank on a timely basis.

                  SECTION 8.4 DRAWDOWNS

                  The Bank, upon accepting Bankers' Acceptances on a Drawdown
shall exchange the Bankers' Acceptance for the Bank draft, certified cheque or
other medium of payment of the purchaser acceptable to the Bank equal in amount
to the Discount Proceeds thereof. The Bank shall pay or credit to the account of
the Borrower, an amount equal to the Discount Proceeds without deduction in same
day funds.

                  SECTION 8.5 ROLLOVERS

                  In the case of a Rollover of the Bankers' Acceptance, the Bank
shall exchange the Bankers' Acceptance for a bank draft, certified cheque or
other medium of payment of the purchaser acceptable to the Bank for the Discount
Proceeds thereof. In order to satisfy the continuing liability of the Borrower
to the Bank for the principal amount of the maturing Bankers' Acceptance, the
Bank shall receive for its own account the Discount Proceeds of such new
Bankers' Acceptance and the Borrower shall on the maturity date of the maturing
Bankers' Acceptance pay to the Bank an amount equal to the difference between
the principal amount of


                                     - 40 -
<PAGE>
the maturing Bankers' Acceptance and the Discount Proceeds from the new Bankers'
Acceptance. The Borrower shall assume the risk of non-payment on the purchasers'
medium of payment for Bankers' Acceptances.

                  SECTION 8.6 CONVERSIONS

                  Subject to Section 10.1:

         8.6.1    In the case of a Conversion into the Bankers' Acceptance, the
                  Bank shall exchange the Bankers' Acceptance for the Bank
                  draft, certified cheque or other medium of payment of the
                  purchaser acceptable to the Bank for the Discount Proceeds
                  thereof. In order to satisfy the continuing liability of the
                  Borrower to the Bank for the amount of the converted Loan, the
                  Bank shall receive for its own account the Discount Proceeds
                  of the Bankers' Acceptance and the Borrower shall, on the
                  Conversion Date, pay to the Bank the difference between the
                  principal amount of the Bankers' Acceptance and the Discount
                  Proceeds therefrom.

         8.6.2    In the case of a Conversion of Bankers' Acceptances into
                  another type of Loan, in order to satisfy the continuing
                  liability of the Borrower to the Bank for the amount of the
                  Bankers' Acceptances, the Bank shall record the obligation of
                  the Borrower to the Bank as a Loan in the type into which the
                  obligation has been converted.

                  SECTION 8.7 ALTERNATIVE BORROWINGS

         8.7.1    Where the Borrower requests a Loan by way of Bankers'
                  Acceptances, the Bank may, at its option, make available to
                  the Borrower prior to 10:00 a.m. (Toronto time) on the
                  Drawdown Date, Rollover Date or Conversion Date, as the case
                  may be, for such Loan by way of Bankers' Acceptances a
                  Canadian Dollar loan (the "ALTERNATE LOAN") in a principal
                  amount equal to the principal amount of such Loan by way of
                  Bankers' Acceptance. Such Alternate Loan shall be funded in
                  the same manner as a Loan is funded pursuant to Section 2.8.
                  Such Alternate Loan shall have the same term as the Bankers'
                  Acceptances for which it is a substitute and shall bear such
                  rate of interest per annum as shall permit the Bank to obtain
                  the same effective yield as if the Bank had accepted and
                  purchased Bankers' Acceptances and furnished an amount equal
                  to the Discount Proceeds in accordance with Section 8.2.
                  Interest shall be calculated for such Alternate Loan in
                  advance on the Drawdown Date, Rollover Date or Conversion
                  Date, as the case may be, and the Bank shall deduct such
                  calculated amount from the principal amount of such Alternate
                  Loan.

         8.7.2    On the Drawdown Date, Rollover Date or Conversion Date, as the
                  case may be, the Borrower shall pay or cause to be paid to the
                  Bank an amount equal to the Bankers' Acceptance Fee which
                  would have been payable to the Bank if it had accepted
                  Bankers' Acceptances.

         8.7.3    If the Bank intends to make a Loan by way of an Alternative
                  Loan pursuant to Section 8.7.2, it shall give to the Borrower
                  notice of the decision by the Bank to make Alternative Loans
                  in lieu of or in addition to Loans by way of Bankers
                  Acceptances, such notice to apply to all further Loans by the
                  Bank in respect of Bankers' Acceptances until further notice
                  is given by the Bank to the Borrower.

                  SECTION 14.5 SUCCESSOR CORPORATION

                  The Borrower shall not, and shall not permit any Subsidiary
to, enter into any transaction whereby all or substantially all of its
undertaking, property and assets would become the property of any other
corporation (herein called a "SUCCESSOR CORPORATION") whether by way of
reconstruction, reorganization, recapitalization, consolidation, amalgamation,
merger, transfer, sale or otherwise, unless:

         14.5.1   prior to or contemporaneously with the consummation of such
                  transaction the Borrower, or such Subsidiary, as the case may
                  be, and the successor corporation shall have executed such
                  instruments and done such things as, in the opinion of
                  counsel, are necessary or advisable to establish that upon the
                  consummation of such transaction:

         (a)      the successor corporation will have assumed all the covenants
                  and obligations of the Borrower, or such Subsidiary, as the
                  case may be, under this Agreement, and

         (b)      this Agreement will be a valid and binding obligation of the
                  successor corporation entitling the Bank, as against the
                  successor corporation, to exercise all its rights under this
                  Agreement;

         14.5.2   such transaction shall be on such terms and shall be carried
                  out in such manner as to not be materially prejudicial to the
                  rights and powers of the Bank hereunder; and

         14.5.3   such transaction shall not result in the assets of the
                  successor corporation being subjected to any encumbrances
                  other than Permitted Encumbrances.

                  SECTION 15.1 EVENTS OF DEFAULT

                  The occurrence of any one or more of the following events
(each such event being herein referred to as an "EVENT OF DEFAULT") shall

         15.1.1   if the Borrower defaults in payment of the principal of any
                  Loan when due and payable and such default continues

                  by the Bank to the Borrower specifying such default and
                  requiring the Borrower to put an end to the same (which said
                  notice may be given by the Bank, in its discretion);

         15.1.2   if the Borrower defaults in payment of (i) any interest

                  (ii) any fee with respect to the Bankers' Acceptance, (iii)
                  any Unused Line Fee, or (iv) any other amount payable by
                  either Borrower hereunder when due and payable and such
                  default continues unremedied for four Banking Days after
                  notice of such default by the Bank to the Borrower specifying
                  such default and requiring the Borrower to put an end to the

                  in this Agreement, the Documents or the Security Documents
                  (other than a covenant or condition whose breach or default in
                  performance is elsewhere in this Section specifically dealt
                  with) and such default continues unremedied for 15 Banking
                  Days after notice of such default by the Bank to the Borrower
                  specifying such default and requiring the Borrower to put an
                  end to the same;

         15.1.4   if any Guarantee of any Guarantee Subsidiary ceases to be
                  enforceable against the Guarantor thereunder;

         15.1.5   if any Guarantor fails to pay any amount when due under any
                  Guarantee;

         15.1.6   if the Borrower or any Guarantee Subsidiary is at any time not
                  Solvent;

         15.1.7   if in the sole judgment of the Bank, reasonably exercised, any
                  party to the Purchase Agreement fails to fully perform the
                  covenants, terms and conditions on its part to be performed
                  pursuant to the Purchase Agreement which could reasonably be
                  expected to have a Material Adverse Effect, and such failure

<PAGE>
                  continues unremedied for 15 Banking Days after notice of such
                  failure by the Bank to the Borrower specifying such failure;

         15.1.8   if one or more events of default as defined in agreements,
                  indentures or instruments evidencing, or under which, any

                  been made therefor), is outstanding and such indebtedness
                  shall be capable of acceleration so that the same shall be or
                  have become due and payable or subject to a right to become
                  due and payable prior to the date on which the same would
                  otherwise become due and payable;

         15.1.9   if a decree or order of a court having jurisdiction in the
                  premises is entered adjudging either Borrower or any Guarantee

                  be rendered by a court of record against the Borrower or any
                  Guarantee Subsidiary in any jurisdiction or jurisdictions in
                  which any such party has property or assets which are material
                  to the business, operations or financial condition of the

                  have been incorrect or misleading in any material respect in
                  respect of the business, operations or financial condition of
                  the Borrower and its Subsidiaries taken as a whole as of the

                  31, 2003 Audited Balance Sheet for any item which could
                  reasonably be expected to have a Material Adverse Effect.

                  SECTION 15.2 ACCELERATION

                  If a Major Change in Ownership or any Event of Default shall
occur and be continuing, the entire principal amount of Loans then outstanding
and all accrued and unpaid interest thereon and all other payments due
hereunder, at the option of the Bank become immediately due and payable with
interest thereon, at the rate or rates determined as herein provided, to the
date of actual payment thereof, all without notice, presentment, protest,
demand, notice of dishonor or any other demand or notice whatsoever, all of
which are hereby expressly waived by the Borrower. In such event the Bank may,
in its discretion, exercise any right or recourse, or proceed by any action,
suit, remedy or proceeding against the Borrower, authorized or permitted by law
for the recovery of all the indebtedness and liabilities of the Borrower to the
Bank, or any combination of the foregoing, and proceed to exercise any and all
rights hereunder and no such remedy for the enforcement of the rights of the
Bank shall be exclusive of or dependent on any other remedy but any one or more
of such remedies may from time to time be exercised independently or in
combination.

                  SECTION 15.3 DEFAULT INTEREST

                  If an Event of Default or a Major Change in Ownership shall

of Credit, L/C Liabilities or Libor Loans, at


                                     - 71 -
<PAGE>
any time, to U.S. Base Rate Loans. Interest shall accrue in respect of all
Obligations outstanding at that time:

         15.3.1   on each U.S. Base Rate Loan at the Interest Rate then in
                  effect plus 2% per annum; and

         15.3.2   on L/C Liabilities in respect of each Letter of Credit which
                  is denominated in U.S. Dollars, and each Libor Loan, which the
                  Bank has not then converted to a U.S. Base Rate Loan, at the
                  Interest Rate then in effect for U.S. Base Rate Loans plus 2%
                  per annum; and

         15.3.3   on L/C Liabilities in respect of each Letter of Credit which
                  is denominated in Canadian Dollars, Canadian Prime Rate Loan,
                  Banker's Acceptance, which the Bank has not then converted to
                  a U.S. Base Rate Loan, at the Interest Rate then in effect for
                  Canadian Prime Rate Loans plus 2% per annum;

together in each case with interest on all overdue interest at the same rate,
from the date of the Event of Default or Major Change in Ownership in the case
of each U.S. Base Rate Loan and Canadian Prime Rate Loan outstanding on the such
date, or from the date of conversion in the case of any U.S. Base Rate Loan into
which a Letter of Credit, L/C Liabilities or Banker's Acceptance is converted
under this Section, for so long as such default shall continue, before and after
judgment, such interest to be payable on demand.

                  SECTION 15.4 REMEDIES CUMULATIVE AND WAIVERS

                  For greater certainty, it is expressly understood and agreed
that the respective rights and remedies of the Bank hereunder or under any other
document or instrument executed pursuant to this Agreement are cumulative and
are in addition to and not in substitution for any rights or remedies provided
by law or by equity; and any single or partial exercise by the Bank of any right
or remedy for a default or breach of any term, covenant, condition or agreement
contained in this Agreement or other document or instrument executed pursuant to
this Agreement shall not be deemed to be a waiver of or to alter, affect or
prejudice any other right or remedy or other rights or remedies to which the
Bank may be lawfully entitled for such default or breach. Any waiver by the Bank
of the strict observance, performance or compliance with any term, covenant,
condition or agreement herein contained and any indulgence granted, either
expressly or by course of conduct, by the Bank shall be effective only in the
specific instance and for the purpose for which it was given and shall be deemed
not to be a waiver of any rights and remedies of the Bank under this Agreement
or any other document or instrument executed pursuant to this Agreement as a
result of any other default or breach hereunder or thereunder.

                  SECTION 15.5 TERMINATION OF BANK'S OBLIGATIONS

                  The occurrence of an Event of Default or a Major Change in
Ownership shall relieve the Bank of all obligations to permit any further
Drawdowns hereunder.

                             CHANGE OF CIRCUMSTANCES

                  SECTION 16.1 MARKET DISRUPTION

                  In the event that at any time subsequent to the giving of a
Drawdown Notice, Rollover Notice or Conversion Notice to the by the Borrower
with regard to any Libor Loan but before the date of the Drawdown, Rollover or
Conversion, as the case may be, the Bank make a determination, which shall be
binding upon the Borrower, that:

         16.1.1   by reason of circumstances affecting the London interbank
                  market adequate and fair means do not exist for ascertaining
                  the rate of interest with respect to a Libor Loan during the
                  Interest Period selected;

         16.1.2   the making or continuing of the Libor Loan by the Bank has
                  been made impracticable by the occurrence of an event which
                  materially or adversely affects the London interbank market;
                  or

         16.1.3   the cost to the Bank of funding the Libor Loan for the
                  immediately following Interest Period does not accurately
                  reflect the effective cost of the Bank' funding for that
                  Interest Period,

then the Bank shall give notice thereof to the Borrower and the Borrower shall,
within one Banking Day after receipt of such notice, give the Bank a revised
Drawdown Notice or a Conversion Notice, as the case may be, which specifies the
Drawdown of a Canadian Prime Rate Loan, a U.S. Base Rate Loan, on the last day
of the applicable Interest Period. In the event the Borrower fails to give, if
applicable, a Conversion Notice, such Libor Loan shall be converted on the last
day of the applicable Interest Period, to the extent possible, into a U.S. Base
Rate Loan.

                  SECTION 16.2 CHANGE IN LAW

In the event of any change after the date hereof in any applicable law, rule,
guideline, regulation, treaty or official directive (whether or not having the
force of law) or in the interpretation or application thereof by any court or by
any governmental agency, central bank or other authority or entity charged with
the administration thereof in Canada or the United States of America which now
or hereafter:

         16.2.1   subjects the Bank to any tax (other than withholding tax) or
                  changes the basis of taxation, or increases any existing tax,
                  on payments of principal, interest, fees or other amounts
                  payable by the Borrower to the Bank under this Agreement
                  (except for taxes on the overall net income of the Bank);

         16.2.2   imposes, modifies or deems applicable any reserve, special
                  deposit or similar requirements against assets held by, or
                  deposits in or for the account of or loans by or any other
                  acquisition of funds by, an office of the Bank; or

         16.2.3   imposes on the Bank or expects there to be maintained by the
                  Bank any capital adequacy or additional capital requirements
                  in respect of any Loans or the Credit Facility hereunder, or
                  any other condition with respect to this Agreement,

and the result of any of the foregoing shall be to increase the cost to, or
reduce the amount of principal, interest or other amount received or receivable
by the Bank hereunder or its effective return hereunder in respect of making,
maintaining or funding the Loan under the Credit Facility the Bank shall
determine that amount of money which shall compensate the Bank for such increase
in cost or reduction in income (herein referred to as "ADDITIONAL
COMPENSATION"). Upon the Bank having determined that it is entitled to
Additional Compensation in accordance with the provisions of this Section, the
Bank shall, within 20 days, so notify the Borrower. The Borrower shall pay to
the Bank within 10 Banking Days of the giving of such notice and receipt of the
aforementioned certificate the Bank's Additional Compensation calculated to the
date of such notification. The Bank shall be entitled to be paid such Additional
Compensation from time to time to the extent that the provisions of this Section
are then applicable. The Bank shall endeavor to limit the incidence of any such
Additional Compensation, including seeking recovery for the account of the
Borrower, by appealing any assessment at the expense of the Borrower upon the
Borrower's request. The Bank shall eliminate such Additional Compensation should
the cause of the same be rescinded, removed, repealed or withdrawn.

                  SECTION 16.3 REPAYMENT OF AFFECTED LOAN

                  Notwithstanding the provisions hereof, if the Bank gives the
notice provided for in Section 16.2 with respect to any Loan (an "AFFECTED
LOAN"), the Borrower may repay in full without penalty the full amount of the
Affected Loan outstanding together with accrued and unpaid interest on the
principal amount so prepaid up to the date of such prepayment, such Additional
Compensation as may be applicable to the date of such payment and all costs,
losses and expenses incurred by the Bank by reason of the liquidation or
re-employment of deposits or other funds resulting from the repayment of such
Affected Loan or any part thereof on other than the last day of the applicable
Interest Period, and upon such payment being made that Bank's obligations to
make such Affected Loans to the Borrower under this Agreement shall terminate.
The Bank shall prepare a certificate of a duly authorized officer of the Bank
setting forth the basis of calculation thereof and such certificate shall be
delivered by the Bank to the Borrower. If pursuant to the provisions of this
Section or any other provision hereof the Borrower become obliged to pay such
Additional Compensation or such costs, losses or expenses, the Bank shall use
its best efforts to minimize such Additional Compensation and such costs, losses
or expenses.

                  SECTION 16.4 ILLEGALITY

                  If, in Canada or the United States of America the adoption of
any applicable law, regulation, treaty or official directive (whether or not
having the force of law) or any change therein or in the interpretation or
application thereof by any court or by any governmental or other authority or
central bank or comparable agency or any other entity charged with the
interpretation or administration thereof or compliance by the Bank with any
request or direction (whether or not having the force of law) of any such
authority, central bank or comparable agency or entity, now or hereafter makes
it unlawful or impossible for the Bank to make, fund or


                                     - 74 -
<PAGE>
maintain a Loan under the Credit Facility or to give effect to its obligations
in respect of such Loan, the Bank may, by written notice thereof to the Borrower
declare its obligations under this Agreement to be terminated whereupon the same
shall forthwith terminate, and the Borrower shall repay within the time required
by such law (or at the end of such longer period as the Bank at its discretion
has agreed) the principal of the Loan together with accrued interest, such
Additional Compensation as may be applicable to the date of such payment and all
costs, losses and expenses incurred by the Bank by reason of the liquidation or
re-employment of deposits or other funds resulting from the repayment of such
Loan or any part thereof on other than the last day of the applicable Interest
Period. The Bank shall prepare a certificate of a duly authorized officer of the
Bank setting forth the basis of calculation thereof and such certificate shall
be delivered by the Bank to the Borrower. If pursuant to the provisions of this
Section or any other provision hereof the Borrower becomes obliged to pay such
Additional Compensation or such costs, losses or expenses, the Bank shall use
its best efforts to minimize such Additional Compensation and such costs, losses
or expenses. If any such change shall only affect a portion of the Bank's
obligations under this Agreement which is, in the opinion of the Bank severable
from the remainder of this Agreement so that the remainder of this Agreement may
be continued in full force and effect without otherwise affecting any of the
obligations of the Bank or the Borrower hereunder, the Bank shall only declare
its obligations under that portion so terminated.

Agreement, the Borrower further agree to pay within 10 Banking Days of demand by
Bank all reasonable costs and expenses in connection with the preparation or
review of waivers, consents and amendments and questions of interpretation of
this Agreement and in connection with the establishment of the validity and
enforceability of this Agreement and the preservation or enforcement of rights
of the Bank under this Agreement and other documents to be delivered hereunder,
including, without limitation, all reasonable costs and expenses sustained by
the Bank as a result of any failure by the Borrower to perform or observe their
obligations contained in this Agreement and the other documents to be delivered
hereunder.

                  SECTION 17.2 INDEMNIFICATION BY TUE BORROWER

         17.2.1   In addition to any liability of the Borrower to the Bank under
                  any other provision hereof, the Borrower and its Subsidiaries
                  shall indemnify the Bank and hold the Bank harmless against
                  any reasonable loss or expense incurred by the Bank to third
                  parties as a result of any failure by the Borrower to fulfill
                  any of its obligations hereunder including, without
                  limitation, any cost or expense incurred by reason of the
                  liquidation or re-employment in whole or in part of deposits
                  or other funds required by the Bank to fund the Bankers'
                  Acceptance or to fund or maintain any Loan as a result of the
                  Borrower's failure to complete a Drawdown or to make any
                  payment, repayment or prepayment on the date required
                  hereunder or specified by it in any notice given hereunder;
                  the Borrower's failure to provide for the payment to the Bank
                  the full principal amount of the Bankers' Acceptance on its
                  maturity date; the Borrower's failure to pay any other amount,

                  Acceptance before the maturity date of the Bankers'
                  Acceptance; or the Borrower's failure to give any notice
                  required to be given by it to the Bank hereunder.

         17.2.2   The Borrower shall indemnify the Bank and each director,
                  officer, employee and affiliate of the Bank (an "INDEMNIFIED
                  PARTY") in connection with any expenses, losses, claims,
                  damages or liabilities to which any such Indemnified Party may
                  become subject insofar as such losses, claims, damages, or
                  liabilities (or actions in respect thereof) arise out of or in
                  any way relate or result from the actions of the Borrower or
                  any of its Subsidiaries in connection with the use of Loans,
                  and to reimburse such Indemnified Party for any legal or other
                  expenses incurred in connection with the investigating,
                  defending or participating in any such loss, claim, damage,
                  liability or action. Notwithstanding the foregoing the

                  the Bank pursuant to Articles 16 or 17 within a period of one
                  year after the Bank first had knowledge of the facts giving
                  rise to the claim and failing the giving of such notice within
                  such time period the claim shall be extinguished and the Bank
                  shall have no further claim thereon.

                  SECTION 17.3 INTEREST ON UNPAID COSTS AND EXPENSES

                  Subject always to the provisions of Section 15.3 hereof,

                  SECTION 18.1 EXCHANGE AND CONFIDENTIALITY OF INFORMATION

                  The Bank acknowledges the confidential nature of the
financial, operational and other information and data provided and to be
provided to them by the Borrower pursuant hereto (the "INFORMATION") and agree
to use all reasonable efforts to prevent the disclosure thereof. Notwithstanding
the foregoing, the Bank may disclose all or any part of the Information if, in
its opinion, such disclosure is desirable or required in connection with any
actual or threatened judicial, administrative or governmental proceeding or any
investigation by any judicial authority, law enforcement agency or taxation
authority, or any other process under which it is legally compelled or otherwise
required to make to avoid standing liable for contempt or suffering other
material censure or penalty, including any proceeding or investigation under or
in respect of any rule or regulation promulgated by any banking regulatory
authority, securities regulatory authority, stock exchange or securities
commission, and it shall incur no liability in respect of any disclosure of
information to any, or pursuant to any such requirement.

                  The Bank agrees with the Borrower, however that it shall
endeavor provide the Borrower with notice of any such anticipated disclosure of
Information so that the Borrower may, at its sole expense, seek a protective
order or other appropriate relief, or waive compliance with the provisions of
this Section. If such protective order or other remedy is not obtained or the
Borrower waives compliance with this Section, then the Bank will furnish only
that portion of the Information which, in its sole opinion, it is legally
required to furnish. Notwithstanding the foregoing, the Bank shall not be liable
to the Borrower for any failure on the part of the Bank to give notice to the
Borrower pursuant to this Section.

         18.4.1   The Borrower hereby irrevocably submits to the jurisdiction of

<PAGE>
                  issued in respect of any such action or proceeding. The
                  Borrower agrees that a final judgment in any such action or
                  proceeding shall be conclusive and may be enforced in other
                  jurisdictions by suit on the judgment or in any other manner
                  provided by law.

                  SECTION 18.5 JUDGMENT CURRENCY

         18.5.1   If for the purpose of obtaining or enforcing judgment against
                  the Borrower or any Subsidiary of the Borrower in any court in
                  any jurisdiction, it becomes necessary to convert into any
                  other currency (such other currency being hereinafter in this
                  Section referred to as the "JUDGMENT CURRENCY") an amount due
                  in Canadian Dollars or United States Dollars under this
                  Agreement, the conversion shall be made at the rate of
                  exchange prevailing on the Banking Day immediately preceding
                  the date of actual payment of the amount due, in the case of
                  any proceeding in the courts of any jurisdiction, including
                  the Province of Alberta, if the courts thereof will give
                  effect to such conversion being made on such date and
                  otherwise on the date on which the judgment is given, (the
                  date as of which such conversion is made pursuant to this
                  Section being hereinafter in this Section referred to as the
                  "JUDGMENT CONVERSION DATE").

         18.5.2   If, in the case of any proceeding in the court of any
                  jurisdiction referred to in Section, there is a change in the
                  rate of exchange prevailing between the Judgment Conversion
                  Date and the date of actual payment of the amount due, the
                  Borrower shall pay such additional amount (if any, but in any
                  event not a lesser amount) as may be necessary to ensure that
                  the amount paid in the Judgment Currency, when converted at
                  the rate of exchange prevailing on the date of payment, will
                  produce the amount of Canadian Dollars or United States
                  Dollars, as the case may be, which could have been purchased
                  with the amount of Judgment Currency stipulated in the
                  judgment or judicial order at the rate of exchange prevailing
                  on the Judgment Conversion Date.

         18.5.3   Any amount due from the Borrower under the provisions of
                  Section shall be due as a separate debt and shall not be
                  affected by judgment being obtained for any other amounts due
                  under or in respect of this Agreement.

         18.5.4   The term "RATE OF EXCHANGE" in this Section means the noon
                  rate of exchange for Canadian interbank transactions in
                  Canadian Dollars or United States Dollars, as the case may be,
                  in the Judgment Currency published by the Bank of Canada for
                  the day in question, or if such rate is not so published by
                  the Bank of Canada, such rate shall mean the simple average of
                  the spot rates quoted for wholesale transactions by LaSalle
                  Bank National Association, in Chicago, Illinois at


                                     - 79 -
<PAGE>
                  approximately noon (Toronto time) on that date in accordance
                  with its normal practice.

                  SECTION 18.6 BENEFIT OF THE AGREEMENT

                  This Agreement shall enure to the benefit of and be binding
upon the Borrower and the Bank, and their respective successors and assigns.

                  SECTION 18.7 ASSIGNMENT AND NOVATION

                  The Bank may not, without the prior written consent of the
Borrower, assign their respective rights and obligations under this Agreement
and novate the assignee into this Agreement, except that the Bank may, in
consultation with the Borrower, at any time and from time to time, sell, assign,
transfer or otherwise grant an interest in any Loan to a Subsidiary or Affiliate
of the Bank.

                  SECTION 18.8 SEVERABILITY

                  Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall not invalidate the remaining provisions
hereof and any such prohibition or unenforceability in any jurisdiction shall
not invalidate or render unenforceable such provision in any other jurisdiction.
