1.013 FINANCIAL TERMS

     (1) All accounting terms not otherwise defined in this Agreement will have
the meanings assigned to such terms by GAAP.  The Borrowers acknowledge and
agree that the various financial terms defined and used in this Agreement, and
the availability of Accommodation, and the interest rates, Bankers' Acceptance
fees, Letter of Credit fees and stand-by fees set forth in Article Three and
the various financial covenants under Section 8.03, have all been established
and agreed upon on the basis of the accounting policies, practices, principles
and calculation methods or components thereof adopted and applied by the Cdn.
Borrower in the preparation of the Cdn. Borrower's December 31, 1996 annual
consolidated audited financial statements (the "FINANCIAL STATEMENTS").
Accordingly, although the Cdn. Borrower shall be entitled to implement any
change or modification in accordance with GAAP to any such accounting policies,
practices, principles or calculation methods or components thereof, for the
purpose of this Agreement, all accounting terms defined or used in this
Agreement (including, without limitation, those specifically referred to above)
shall at all times be interpreted in accordance with, and all financial
statements delivered or supplied under this Agreement shall be accompanied by a
reconciliation so as to show the financial position, performance and results of
the Restricted Parties in accordance with, GAAP (on a Modified Consolidated
basis where required by this Agreement) using, and shall at all times be
applied in accordance with GAAP (on a Modified Consolidated basis where
required by this Agreement) in a manner consistent with, the policies,
practices, principles and calculation methods or components thereof adopted by
the Cdn. Borrower with respect to the Financial Statements, irrespective of any
change or modification thereto implemented by the Cdn. Borrower (provided
however that if the Cdn. Borrower changes such policies, practices, principles
or calculation methods, the Cdn. Borrower may for the purpose of the accounting
terms defined in this Agreement (a) implement any such change which is neither
material in nature nor could have a material impact on the interpretation or
calculation of the financial terms or covenants set forth in this Agreement,
provided that the Cdn. Borrower has given the Administrative Agent prior
written notice of the applicable change, and (b) implement any such change
which is material in nature or which could have a material impact on the
interpretation or calculation of the financial terms or covenants set forth in
this Agreement provided that the Cdn. Borrower has given the Administrative
Agent 30 days' prior written notice of such change and the Required Lenders
have given their prior written approval to the Cdn. Borrower implementing such
change).

     (2) If there is a Disposition of, or a closure of, any business,
undertaking or operation of a Restricted Party (collectively a "SALE"),
Interest Expense prior to the date of such Sale ("SALE RELATED HISTORICAL
INTEREST EXPENSE") will be adjusted downwards, effective as of the date of such
Sale, so that any Sale Related Historical Interest Expense for any period used
in any


   49

                                                                   SECTION 1.03



                                - 41 -


calculations of financial terms or covenants under this Agreement after the
date of such Sale is reduced on a proportionate basis to reflect a reasonable
estimate of what such Sale Related Historical Interest Expense for such period
would have been if such Sale had been completed at the beginning of such
period.  Any such adjustment to Sale Related Historical Interest Expense over
any period shall be calculated based on the formula set forth below.  The
number of completed calendar months immediately preceding such Sale occurring
during the respective four Financial Quarter period will be determined and is
referred to as "N".  Sale Related Historical Interest Expense will be adjusted
downward for such period by an amount equal to:

         N/12 x (NSP x ACOB)

    where:


         NSP  =  the net cash sales proceeds received from such Sale or, 
                 in the case of a Sale which is a closure, the book value at 
                 the date of such Sale of the business or undertaking closed

         ACOB =  the average rate for the applicable period for Debt of the 
                 Cdn. Borrower under this Agreement.


     (3) If there is an Acquisition by a Restricted Party, Interest Expense
prior to the date of such Acquisition ("ACQUISITION RELATED HISTORICAL INTEREST
EXPENSE") will be adjusted upwards, effective as of the date of such
Acquisition, so that any Acquisition Related Historical Interest Expense for
any period used in any calculation of financial terms or covenants under this
Agreement after the date of such Acquisition is increased to reflect the
incremental Debt issued, incurred or assumed by the Restricted Parties to
effect such Acquisition calculated at a rate per annum equal to the rate of
interest applicable to such Debt at the date of such Acquisition (in the case
of Debt which was issued or incurred in connection with such Acquisition and at
the average rate of interest on such Debt for such period in the case of Debt
assumed in connection with such Acquisition) as if such incremental Debt had
been issued, incurred or assumed at the beginning of such period.

     (4) If there is a Sale, EBITDA prior to the date of such Sale ("SALE
RELATED HISTORICAL EBITDA") will be adjusted downwards, effective as of the
date of such Sale, so that any Sale Related Historical EBITDA for any period
used in any calculations of financial terms or covenants under this Agreement
after the date of such Sale is reduced on a proportionate basis to reflect a
reasonable estimate of what Sale Related Historical EBITDA for such period
would have been if such Sale had been completed at the beginning of such
period.  For greater certainty, any adjustment to EBITDA under this subsection
in connection with any Sale will be made without duplication of any adjustment
made to Interest Expense under subsection 1.03(2) in connection with such Sale.



   50

                                                                   SECTION 1.03


                                - 42 -


     (5) If there is an Acquisition by a Restricted Party of a new division,
business, undertaking or operation, EBITDA prior to the date of such
Acquisition ("ACQUISITION RELATED HISTORICAL EBITDA") will be adjusted upward,
effective as of the date of such Acquisition, so that any Acquisition Related
Historical EBITDA for any period used in any calculations of financial terms or
covenants under this Agreement after the date of such Acquisition is increased
to reflect a reasonable estimate of what Acquisition Related Historical EBITDA
for such period would have been had such Acquisition been completed at the
beginning of such period (and for greater certainty such upward adjustment will
not include any expected synergies).  For greater certainty, any adjustment to
EBITDA under this subsection in connection with any Acquisition will be made
without duplication of any adjustment made to Interest Expense under subsection
1.03(3) in connection with such Acquisition.

1.014 NUMBER, GENDER AND EXPRESSIONS 

     Words importing the singular number only will include the plural and vice
versa, words importing gender will include all genders and words importing any
type or category of Persons will include all types and categories of Persons.

term or expression will have a corresponding meaning.

time will mean Toronto, Ontario local time.  Time shall be of the essence of
this Agreement and each of its provisions.

1.016 NON-BUSINESS DAYS

     Unless otherwise expressly provided in this Agreement, whenever any
payment is stated to be due on a day other than a Business Day, the payment
will be made on the immediately following Business Day.  Notwithstanding the
foregoing, if with respect to any payment of principal or interest on a LIBOR
Loan the succeeding Business Day falls in the next calendar month, the due date
for payment of such principal or interest shall be the next preceding Business
Day.  In the case of interest or fees payable pursuant to the terms of this
Agreement, the extension or contraction of time will be considered in
determining the amount of interest and fees.  Unless otherwise expressly
provided in this Agreement, whenever any action to be taken is stated or
scheduled to be required to be taken on, or (except with respect to the
calculation of interest or fees) any period of time is stated or scheduled to
commence or terminate on, a day other than a Business Day, the action will be
taken or the period of time will commence or terminate, as the case may be, on
the immediately following Business Day.

1.017 CONFLICTS 


   51

                                                                   SECTION 1.07



                                     - 43 -


     In the event of a conflict, discrepancy, difference or ambiguity in or

Borrower)


   52

                                                                   SECTION 1.11

without allowance or deduction for deemed re-investment or otherwise, both
before and after maturity and before and after default and/or judgment, if any,
until payment of the amount on which such interest is accruing, and interest
will accrue on overdue interest, if any.

     (2) Unless otherwise stated, wherever in this Agreement reference is made
to a rate of interest or rate of fees "per annum" or a similar expression is
used, such interest or fees will be calculated on the basis of a calendar year
of 365 days or 366 days, as the case may be, and using the nominal rate method
of calculation, and will not be calculated using the effective rate method of
calculation or on any other basis that gives effect to the principle of deemed
re-investment of interest.

     (3) For the purposes of the Interest Act (Canada) and disclosure under
such act, whenever interest to be paid under this Agreement is to be calculated
on the basis of a year of 365 days or 360 days or any other period of time that
is less than a calendar year, the yearly rate of interest to which the rate
determined pursuant to such calculation is equivalent is the rate so determined
multiplied by the actual number of days in the calendar year in which the same
is to be ascertained and divided by either 365, 360 or such other period of
time, as the case may be.


1.14 GOVERNING LAW

ADMINISTRATIVE AGENT AND THE LENDERS UNDER THIS AGREEMENT SHALL BE CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE PROVINCE OF ONTARIO AND THE
LAWS OF CANADA APPLICABLE IN THE PROVINCE OF ONTARIO. EACH OF THE BORROWERS
VOLUNTARILY AND IRREVOCABLY SUBMITS ITSELF TO THE



   53

                                                                   SECTION 1.14


                                - 45 -


JURISDICTION OF ANY COMPETENT FEDERAL OR PROVINCIAL COURT OR TRIBUNAL IN THE
PROVINCE OF ONTARIO TO ENABLE THE ADMINISTRATIVE AGENT OR THE LENDERS OR ANY OF
THEM TO COMMENCE AND CARRY TO A CONCLUSION ANY SUIT, ACTION OR PROCEEDING FOR
THE COLLECTION OF ANY AND ALL AMOUNTS PAYABLE BY SUCH BORROWER UNDER THE CREDIT
DOCUMENTS AND/OR THE ENFORCEMENT OF ANY OTHER RIGHT OR SECURITY GIVEN TO THE
ADMINISTRATIVE AGENT OR THE LENDERS OR ANY OF THEM BY SUCH BORROWER IN
CONNECTION WITH ANY AMOUNT PAYABLE UNDER ANY CREDIT DOCUMENT.  Each of the
Borrowers further agrees that any final judgment or decree against such
Borrower and/or its property in any such suit, action or proceeding shall be
conclusive on such Borrower and such property and all parties in interest, and
may be enforced in any court or tribunal in any other country, province or
state by suit on the judgment or decree, a certified copy of which shall be
conclusive evidence of judgement or decree, as the case may be.  Nothing in
this Section shall be deemed or operate to preclude the Administrative Agent or
any Lender from bringing suit or taking other legal action in any other
jurisdiction to collect the obligations of any Restricted Party or to realize

Administrative Agent or any Lender.  Each of the Borrowers expressly submits

relief as is deemed appropriate by such court.  Each of the Borrowers hereby
waives personal service of the summons, complaint and other process issued in
any such action or suit and agrees that service of such summons, complaints and
other process may be made by registered or certified mail addressed to such
Person at the address of the Cdn. Borrower set forth on the signature page of

THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A
JUDGE APPLYING SUCH APPLICABLE LAWS.  THEREFORE, TO ACHIEVE THE BEST COMBINATION
OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, THE PARTIES HERETO
WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO
RESOLVE ANY DISPUTE, WHETHER SOUNDING IN CONTRACT, TORT, OR OTHERWISE, BETWEEN
THE PARTIES ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE
RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THE CREDIT DOCUMENTS OR
THE TRANSACTIONS UNDER THE CREDIT DOCUMENTS.

     The Borrowers shall use Accommodation obtained by them under the Credit to
refinance all Existing Bank Debt, to finance working capital requirements, the
cost of Acquisitions and Capital Expenditures permitted by this Agreement and

of the first day of the immediately following Financial Quarter (the "QUARTERLY

increase or decrease in the Tranche 2 Cdn. Borrowing Commitments (with any such
increase or decrease resulting in a pro rata increase or decrease to the
Tranche 2 Cdn. Borrowing Commitment of each Cdn. Cross Border Lender) with a
corresponding decrease or increase, as the case may be, in the Tranche 2 U.S.
Borrowing Commitments (with any such decrease or increase resulting in a pro

U.S. Cross Border Lender) (collectively a "TRANCHE 2 COMMITMENT ADJUSTMENT"),
and (B) the LC Line by way of an increase or decrease in the Cdn. LC

corresponding decrease or increase, as the case may be, in the U.S. LC
Commitments (with any such decrease or increase resulting in a pro rata
decrease or increase to the U.S. LC Commitment of each U.S. LC Lender)
(collectively a "LC COMMITMENT ADJUSTMENT"), or (y) confirming that there will
be no Tranche 2 Commitment Adjustment or LC Commitment Adjustment as at the
applicable


   60
                                                                  SECTION 2.03

                                - 52 -

Quarterly Commitment Adjustment Date, provided that failure by the Cdn.
Borrower to deliver any such written notice to the Administrative Agent within
the period required above will be deemed to be delivery by the Cdn. Borrower to
the Administrative Agent of a written notice that there will be no Tranche 2
Commitment Adjustment or LC Commitment Adjustment as at the applicable
Quarterly Commitment Adjustment Date.  Any such Tranche 2 Commitment Adjustment
and LC Commitment Adjustment will become effective on the applicable Quarterly
Commitment Adjustment Date provided that:

      (a)  the sum of the Tranche 2 Cdn. Borrowing Commitments and the Tranche
           2 U.S. Borrowing Commitments after any such Tranche 2 Commitment
           Adjustment must always equal the Tranche 2 Combined Commitments
           immediately prior to such Tranche 2 Commitment Adjustment,

      (b)  the sum of the Cdn. LC Commitments and the U.S. LC Commitments after
           any such LC Commitment Adjustment must always equal the Combined LC
           Commitments immediately prior to such LC Commitment Adjustment,

      (c)  any such increase or decrease under Tranche 2 must be in a minimum
           amount of U.S. $10,000,000 or any larger amount which is a whole
           multiple of U.S. $5,000,000,

      (d)  any such increase or decrease under the LC Line must be in a minimum
           amount of U.S. $2,000,000 or any larger amount which is a whole
           multiple of U.S. $100,000,

      (e)  the Borrowers must prior to the applicable Quarterly Commitment
           Adjustment Date repay sufficient outstanding Accommodation under
           Tranche 2 in accordance with the terms of this Agreement so that,
           immediately after such Tranche 2 Commitment Adjustment on such
           Quarterly Commitment Adjustment Date, the aggregate U.S. Dollar
           Amount of all Accommodation outstanding under Tranche 2 from the
           Cdn. Cross Border Lenders does not exceed the adjusted Tranche 2
           Cdn. Borrowing Commitments (and the aggregate U.S. Dollar Amount of
           all Accommodation outstanding under Tranche 2 from each Cdn. Cross
           Border Lender does not exceed its adjusted Tranche 2 Cdn. Borrowing
           Commitment) and the aggregate U.S. Dollar Amount of all
           Accommodation outstanding under Tranche 2 from the U.S. Cross Border
           Lenders does not exceed the adjusted Tranche 2 U.S. Borrowing
           Commitments (and the aggregate U.S. Dollar Amount of all
           Accommodation outstanding under Tranche 2 from each U.S. Cross
           Border Lender does not exceed its adjusted Tranche 2 U.S. Borrowing
           Commitment).

                                                                  SECTION 2.03

                                - 53 -


      (f)  the Borrowers must prior to the applicable Quarterly Commitment
           Adjustment Date repay sufficient outstanding Accommodation under the
           LC Line in accordance with the terms of this Agreement so that,
           immediately after such LC Commitment Adjustment on such Quarterly
           Commitment Adjustment Date, the aggregate U.S.  Dollar Amount of all
           Accommodation outstanding under the LC Line from the Cdn. LC Lenders
           does not exceed the adjusted Cdn. LC Commitments and the aggregate
           U.S. Dollar Amount of all Accommodation outstanding under the LC
           Line from the U.S. LC Lenders does not exceed the adjusted U.S. LC
           Commitments.

For greater certainty, no Tranche 2 Commitment Adjustment will result in an
increase or decrease to the overall Tranche 2 Combined Commitments of all of
the Cross Border Lenders or to the Tranche 2 Combined Commitment of any
particular Cdn. Cross Border Lender and its Affiliated U.S. Cross Border
Lender.  Rather, any such Tranche 2 Commitment Adjustment will only result in
an increase or decrease, as the case may be, in the Tranche 2 Cdn. Borrowing
Commitment of each Cdn. Cross Border Lender with a corresponding decrease or
increase, as the case may be, in the Tranche 2 U.S. Borrowing Commitment of its
respective Affiliated U.S. Cross Border Lender.  In addition, no LC Commitment
Adjustment will result in an increase or decrease to the overall LC Combined
Commitments of all of the LC Lenders or to the LC Combined Commitment of any
particular Cdn. LC Lender and its Affiliated U.S. LC Lender.  Rather any such
LC Commitment Adjustment will only result in an increase or decrease, as the
case may be, in the Cdn. LC Commitment of each Cdn. LC Lender with a
corresponding decrease or increase, as the case may be, in the U.S. LC
Commitment of its respective Affiliated U.S. LC Lender.

     (2) The Cdn. Operating Lender, the U.S. Operating Lenders or the LC
Lenders may from time to time, with notice to and the consent of the
Administrative Agent and the Cdn. Borrower, and will from time to time at the
request of the Cdn. Borrower and the Administrative Agent, adjust their
Commitments under the Credit (such adjustment to be effective on the date
agreed to by the Administrative Agent and the Cdn. Borrower) by:

      (a)  increasing or reducing their respective Commitments under the Cdn.
           Operating Line (in the case of the Cdn. Operating Lender), the
           applicable U.S. Operating Line (in the case of a U.S. Operating
           Lender) and the LC Line (in the case of the LC Lenders) and

      (b)  making a corresponding decrease or increase, as the case may be, in
           (x) such Lender's Tranche 1 Commitment (if such Lender is also a
           Cdn. Only Lender), (y) the Tranche 2 Combined Commitment of such
           Lender and its Affiliated Cross Border Lender (if such Lender is
           also a Cross Border Lender), or (z) such Lender's Tranche 3
           Commitment (if such Lender is also a U.S. Only Lender) provided
           that:

                                                                  SECTION 2.03

                                - 54 -


              (i)  the sum of the aggregate Commitments of such Lenders (and
                   where applicable their Affiliated Cross Border Lenders)
                   under the Credit shall not increase or decrease as a result
                   of any such adjustment, and

              (ii) any such increase or decrease must be in a minimum amount of
                   U.S. $500,000 or any larger amount which is a whole multiple
                   of U.S. $100,000, and

             (iii) the Borrowers must prior to the applicable adjustment date
                   repay sufficient outstanding Accommodation under the affected
                   Tranches in accordance with the terms of this Agreement so
                   that, immediately after giving effect to such adjustment on
                   such date, the aggregate U.S. Dollar Amount of all
                   Accommodation outstanding under each of the affected Tranches
                   does not exceed the adjusted Commitments of the applicable
                   Lender (or the Applicable Lender and its Affiliated Cross
                   Border Lender, as the case may be, or the Applicable Lender
                   and its Affiliated LC Lender, as the case may be) under the
                   affected Tranches.

     (3)   Except as otherwise specifically stated in this Agreement:

     (a)   each Borrowing by the Cdn. Borrower under Tranche 1 and Tranche 2
           (x) will be made available to the Cdn. Borrower by the Cdn. Only
           Lenders and the Cdn. Cross Border Lenders simultaneously and pro
           rata based on their respective Undisbursed Commitments under Tranche
           1 and Tranche 2 respectively, and (y) will be comprised of the same
           type of Accommodation, with identical maturity dates and LIBOR
           Periods, if applicable, from each such Lender; and

     (b)   each Borrowing by the U.S. Borrower under Tranche 2 and Tranche 3
           (x) will be made available to the U.S. Borrower by the U.S. Only
           Lenders and the U.S. Cross Border Lenders simultaneously and pro
           rata based on their respective Undisbursed Commitments under Tranche
           2 and Tranche 3 respectively, and (y) will be comprised of the same
           type of Accommodation, with identical maturity dates and LIBOR
           Periods, if applicable, from each such Lender.

     (4)   No Lender will be responsible for any default by any other Lender in
its obligation to make Accommodation available to a Borrower nor will the
Commitment of any Lender be increased as a result of any such default, except
as provided in this subsection.  If any Lender fails to make available any
Accommodation under Tranche 1, Tranche 2 or Tranche 3 when required under its
Commitment relative to such Tranche, the Administrative Agent will promptly
notify the other Lenders of such failure, and any Lender which has a Commitment
to such Borrower under any of such Tranches, upon notice to the applicable
Borrower, the


   63
                                                                  SECTION 2.03

                                - 55 -


Administrative Agent and the other Lenders, may make available to such Borrower
within two Business Days after the applicable Borrowing Date the amount (or if
more than one Lender so elects, its pro rata share of the amount as nearly as
practicable in the opinion of the Administrative Agent) of the failed
Accommodation.  The maturity date of the LIBOR Period applicable to all LIBOR
Loans and the maturity date of all Bankers' Acceptances and BA Equivalent Notes
included in the additional Accommodation so made available shall be identical
to the respective maturity dates of the LIBOR Period for any LIBOR Loans, and
of any Bankers' Acceptances and BA Equivalent Notes, that would have been
included in the failed Accommodation and that were included in the
Accommodation made available by the non-defaulting Lenders on the applicable
Borrowing Date.  The Lenders, the Borrowers and the Administrative Agent shall
thereupon enter into documentation, in form and substance satisfactory to the
Administrative Agent, as may be appropriate to evidence the adjustment of the
Commitments relative to the Tranches necessitated by the additional
Accommodation made by any Lender and thereafter the Administrative Agent in its
discretion may adjust the manner in which any Lender or group or groups of
Lenders share in any new Borrowings to ensure that the applicable Lenders or
group of Lenders hold outstanding Accommodation as soon as possible thereafter
on a pro rata basis as contemplated under the other provisions of this
Agreement.  Nothing in this subsection shall be deemed to relieve any Lender of
its obligation to make available any Accommodation when required to do so under
this Agreement, or to prejudice any rights which any Borrower, the
Administrative Agent or any other Lender may have against a defaulting Lender.

1.024   NOTICE OF BORROWING

     (1) Whenever a Borrower desires to obtain a Borrowing (other than a
Borrowing under one of the Operating Lines which will be made available by the
applicable Operating Lender pursuant to arrangements from time to time entered
into between the Cdn. Borrower and the Cdn. Operating Lender and between the
U.S. Borrower and each of the U.S. Operating Lenders), it shall give
irrevocable prior written notice to the Administrative Agent in substantially
the form of Schedule 10 (a "NOTICE OF BORROWING") specifying the identity of
the Borrower; the Tranche or Tranches under which the Borrowing is to be
obtained; the types and amounts of Accommodation desired; the term of any
Bankers' Acceptances or BA Equivalent Notes to be included in such
Accommodation; the LIBOR Period to be applicable to any LIBOR Loans to be
included in such Accommodation; and the date (which shall be a Business Day) on
which such Borrowing is to be obtained (a "BORROWING DATE" which date shall
include the date on which any Accommodation is obtained under subsection
2.05(7), subsection 2.06(3) or Section 2.07 and the date on which the basis on
which interest is calculated on a Loan in U.S. Dollars is converted or renewed
pursuant to a Notice of Conversion/Renewal).  Whenever a Borrower desires to
convert the basis on which interest is calculated on a Loan in U.S. Dollars
from LIBOR (provided that the LIBOR Period for such LIBOR Loan is then
expiring) to the U.S. Base Rate or the U.S. Reference Rate, as the case may be,
(provided that no conversion of a


   64
                                                                  SECTION 2.04

                                - 56 -


part only of any LIBOR Loans will be permitted if such conversion would reduce
the outstanding amount of such LIBOR Loans to less than the applicable minimum
borrowing amount for LIBOR Loans provided for in this Agreement) or from the
U.S. Base Rate or the U.S. Reference Rate, as the case may be, to LIBOR, or to
renew the LIBOR Period for a LIBOR Loan for which the then existing LIBOR
Period is then expiring, it shall give irrevocable prior written notice to the
Administrative Agent in substantially the form of Schedule 11 (a "NOTICE OF
CONVERSION/RENEWAL") specifying the identity of the Borrower; the Tranche or
Tranches under which the conversion or renewal is to be made; the types and
amounts of Accommodation in respect of which the conversion or renewal is to be
made; the LIBOR Period to be applicable to any LIBOR Loans to be included in
such conversion or renewal and the date (which shall be a Business Day and
shall be at the expiry of any LIBOR Period relative to any LIBOR Loan which is
the subject matter of any such conversion or renewal) on which such conversion
or renewal is to take place.  No Accommodation will be included in any
Borrowing if the term of such Accommodation, or any LIBOR Period applicable to
such Accommodation, would mature beyond the Maturity Date.  Without limitation
of any of the conditions precedent set forth in Section 10.02, no Borrower
shall be entitled to obtain (or in the case of an outstanding LIBOR Loan renew
the LIBOR Period therefor), and the Lenders will not be obliged to make
available, Accommodation by way of LIBOR Loans (or renew the outstanding LIBOR
Periods for outstanding LIBOR Loans), Bankers' Acceptances or BA Equivalent
Notes or Letters of Credit at any time that a Default or an Event of Default
has occurred and is continuing.  Except for Accommodation under the Operating
Lines (which will be made available by the applicable Operating Lender pursuant
to arrangements from time to time entered into between the Cdn. Borrower and
the Cdn. Operating Lender and between the U.S. Borrower and each of the U.S.
Operating Lenders), the Lenders will not be obliged to make available on any
Borrowing Date Loans under any Tranche or Tranches in an aggregate amount less
than the applicable minimum amounts set forth in Schedule 12 with respect to
such Tranche or Tranches.  The Administrative Agent will promptly notify the
applicable Lenders of the proposed Borrowing and the particulars of the
Accommodation to be made available by each Lender.

     (2) A Notice of Borrowing requesting any Accommodation under the Credit
and a Notice or Conversion/Renewal shall be given not later than 10:00 a.m. on
the date which is that number of Business Days preceding the applicable
Borrowing Date set forth in Schedule 13 with respect to such type of
Accommodation.


1.025   BANKERS' ACCEPTANCES

     (1) To facilitate the procedures contemplated in this Agreement, the Cdn.
Borrower will from time to time as required by the applicable Lender provide to
the BA Lenders and the Non BA Lenders an appropriate number of executed drafts
drawn by the Cdn. Borrower upon each BA Lender, in the form prescribed by such
BA Lender for bankers' acceptances (each such executed draft being referred to
as a "DRAFT"), and an appropriate number of executed non



   65
                                                                  SECTION 2.05

                                - 57 -


interest-bearing promissory notes of the Cdn. Borrower in favour of each Non BA
Lender, in the form of Schedule 14 (each such promissory note being referred to
as a "BA EQUIVALENT NOTE").  The dates, the maturity dates and the principal
amounts of all Drafts and BA Equivalent Notes delivered by the Cdn. Borrower
shall be left blank, to be completed by the Lenders as required by this
Agreement.  The Drafts or BA Equivalent Notes shall be held by each Lender
subject to the same degree of care as if they were such Lender's own property
kept at the place at which the Drafts or BA Equivalent Notes are ordinarily
kept by such Lender.  No Lender shall be liable for its failure to accept a
Draft or purchase a BA Equivalent Note as required by this Agreement if the
cause of such failure is, in whole or in part, due to the failure of the Cdn.
Borrower to provide Drafts or BA Equivalent Notes to the applicable Lender on a
timely basis.

     (2) The Administrative Agent, promptly following receipt of a Notice of
Borrowing requesting Bankers' Acceptances, shall (i) advise each BA Lender of
the face amount and term of each Draft to be accepted by it, (ii) advise each
Non BA Lender of the face amount and term of the BA Equivalent Note to be
purchased by it, and (iii) advise each BA Lender whether the BA Lenders are
required by such Notice of Borrowing to purchase the Bankers' Acceptances
accepted by them.  The term of all Bankers' Acceptances and BA Equivalent Notes
issued pursuant to any Notice of Borrowing shall be identical.  The face amount
of each Bankers' Acceptance and BA Equivalent Note shall be Cdn. $100,000 or
any whole multiple of Cdn. $100,000, and the aggregate face amount of Bankers'
Acceptances and BA Equivalent Notes issued pursuant to any Notice of Borrowing
under any Tranche or Tranches shall not be less than the applicable amounts set
forth in Schedule 12 with respect to such Tranche or Tranches, as the case may
be.  Each Bankers' Acceptance and BA Equivalent Note shall be dated the
Borrowing Date on which it is issued, and shall be for a term of one, two,
three or six months provided that in no event shall the term of a Bankers'
Acceptance or a BA Equivalent Note extend beyond the Maturity Date.  The
aggregate face amount of the Drafts to be accepted at any time by a BA Lender,
and the face amount of the BA Equivalent Note to be purchased at any time by a
Non BA Lender, shall be determined by the Administrative Agent based upon the
amounts of the respective Commitments under the Tranche or Tranches under which
such Drafts and BA Equivalent Notes are being issued, except that, if the face
amount of any Draft to be accepted by a BA Lender or of the BA Equivalent Note
to be purchased by a Non BA Lender, determined as provided for above, would not
be Cdn. $100,000 or a whole multiple of Cdn. $100,000, the Administrative Agent
in its sole discretion may increase such face amount to the nearest whole
multiple of Cdn. $100,000 or may reduce such face amount to the nearest whole
multiple of Cdn. $100,000.

     (3) Each BA Lender shall complete and accept on the applicable Borrowing
Date Drafts having the face amounts and term advised by the Administrative
Agent pursuant to subsection 2.05(2).  If the BA Lenders are required to
purchase the Bankers' Acceptances accepted by them, each BA Lender shall
purchase on the applicable Borrowing Date the Bankers' Acceptances accepted by
it, for an aggregate price equal to the BA Discount Proceeds of such


   66
                                                                  SECTION 2.05

                                - 58 -

Bankers' Acceptances.  In all other cases, it shall be the responsibility
of the Cdn. Borrower to arrange in accordance with normal market practice for
the sale on each Borrowing Date of the Bankers' Acceptances issued by it on
such Borrowing Date, and for such purpose the Cdn. Borrower shall advise the
Administrative Agent (which shall promptly give the relevant particulars to
each BA Lender) as soon as possible and in any event not later than 11:00 a.m.
on such Borrowing Date of the price for each Bankers' Acceptance payable by the
purchaser of such Bankers' Acceptance and the identity of the Person who will
pay such price to, and take delivery of such Bankers' Acceptance from, the
applicable BA Lender, and such BA Lender is authorized to release such Bankers'
Acceptance to such Person on receipt of a certified cheque or bank draft in an
amount equal to such price.

     (4) Each Non BA Lender, in lieu of accepting Drafts or purchasing Bankers'
Acceptances on any Borrowing Date, will complete and purchase from the Cdn.
Borrower on such Borrowing Date a BA Equivalent Note in a face amount and for a
term identical to the aggregate face amount and term of the Drafts which such
Non BA Lender would have been required to accept on such Borrowing Date if it
were a BA Lender, for a price equal to the BA Discount Proceeds of such BA
Equivalent Note.  Each Non BA Lender shall be entitled without charge to
exchange any BA Equivalent Note held by it for two or more BA Equivalent Notes
of identical date and aggregate face amount (subject to the minimum face amount
specified in Subsection 2.05(2)), and the Cdn. Borrower will execute and
deliver to the Administrative Agent such BA Equivalent Notes upon not less than
five Business Days prior written request for the same to the Cdn. Borrower and
the Administrative Agent shall arrange for delivery of such replacement BA
Equivalent Notes to such Non BA Lender and the return by such Non BA Lender to
the Administrative Agent for delivery to the Cdn. Borrower of the original BA
Equivalent Note for cancellation.

     (5) Upon acceptance of each Draft or purchase of each BA Equivalent Note,
the Cdn. Borrower shall pay to the applicable Lender the related fee specified
in Section 3.09, and to facilitate payment such Lender shall be entitled to
deduct and retain for its own account the amount of such fee from the amount to
be transferred by such Lender to the Administrative Agent for the account of
such Borrower pursuant to subsection 5.01(1) in respect of the sale of the
related Bankers' Acceptance or of such BA Equivalent Note.

     (6) If the Administrative Agent determines in good faith, which
determination shall be final, conclusive and binding upon the Cdn. Borrower,
and so notifies the Cdn. Borrower, that there does not exist at the applicable
time a normal market in Canada for the purchase and sale of bankers'
acceptances, any right of the Cdn. Borrower to require the Lenders to purchase
Bankers' Acceptances and BA Equivalent Notes under this Agreement shall be
suspended until the Administrative Agent determines that such market does exist
and gives notice thereof to the Cdn. Borrower, and any Notice of Borrowing
requesting Bankers' Acceptances shall be deemed to be a Notice of Borrowing
requesting Prime Rate Loans in a similar aggregate principal amount.


   67
                                                                  SECTION 2.05

                                - 59 -


     (7) On the date of maturity of each Bankers' Acceptance or BA Equivalent
Note, the Cdn. Borrower shall pay to the Administrative Agent, for the account
of the holder of such Bankers' Acceptance or BA Equivalent Note, Cdn. Dollars
in an amount equal to the face amount of such Bankers' Acceptance or BA
Equivalent Note, as the case may be.  The obligation of the Cdn. Borrower to
make such payment shall not be prejudiced by the fact that the holder of any
such Bankers' Acceptance is the Lender that accepted such Bankers' Acceptance.
No days of grace shall be claimed by the Cdn. Borrower for the payment at
maturity of any Bankers' Acceptance or BA Equivalent Note.  If the Cdn.
Borrower does not make such payment, from the proceeds of Accommodation
obtained under this Agreement or otherwise, the Lender that accepted such
Bankers' Acceptance or initially purchased such BA Equivalent Note may (but
shall not be obliged to), without receipt of a Notice of Borrowing,
irrespective of whether any applicable conditions precedent under this
Agreement have been met and without waiver of the Default or the Event of
Default constituted by the Cdn. Borrower's failure to make such payment, make a
Prime Rate Loan to the Cdn. Borrower under the Tranche under which such
Bankers' Acceptance was issued or such BA Equivalent Note was purchased in the
face amount of such Bankers' Acceptance or BA Equivalent Note, as the case may
be, and shall promptly give notice of such Loan to the Cdn. Borrower and the
Administrative Agent (which shall promptly give similar notice to the other
Lenders).  The Cdn. Borrower agrees to accept each such Prime Rate Loan and
irrevocably authorizes and directs the applicable Lender to apply the proceeds
of each such Loan in payment of the liability of the Cdn. Borrower with respect
to the related Bankers' Acceptance or BA Equivalent Note.  Notwithstanding any
other provision of this Agreement, all Prime Rate Loans made as contemplated by
this subsection shall be payable on demand by the Administrative Agent or the
applicable Lender.

     (8) If any Bankers' Acceptance or BA Equivalent Note is outstanding on the
Maturity Date or at any time that an Event of Default occurs, the Cdn. Borrower
will immediately, in the case of any Bankers' Acceptance or BA Equivalent Note
outstanding on the Maturity Date, and otherwise immediately upon demand by the
Administrative Agent, pay to the Administrative Agent, for the account of the
holder of such Bankers' Acceptance or BA Equivalent Note, Cdn. Dollars in an
amount equal to the face amount of such Bankers' Acceptance or BA Equivalent
Note, as the case may be.  Such funds (together with interest on such funds)
shall be held by the Agent, subject to Section 9.03, for payment of the
liability of the Cdn. Borrower in respect of such Bankers' Acceptance or BA
Equivalent Note, and shall bear interest for such terms as are selected from
time to time by the Administrative Agent at the wholesale money market rate of
the Administrative Agent for deposits of similar amounts and maturities.  Any
balance of such funds and interest shall be held by the Administrative Agent as
security for the remaining liabilities of the Cdn. Borrower under the Credit
Documents.

     (9) The signature of any duly authorized officer of the Cdn. Borrower on a
Draft or a BA Equivalent Note may be mechanically reproduced in facsimile, and
all Drafts and BA Equivalent Notes bearing such facsimile signature shall be
binding upon the Cdn. Borrower as if they had been manually signed by such
officer, notwithstanding that such Person whose manual


   68
                                                                  SECTION 2.05
                                - 60 -

or facsimile signature appears on such Draft or BA Equivalent Note may no
longer hold office at the date of such Draft or BA Equivalent Note or at the
date of acceptance of such Draft by a BA Lender or at any time thereafter.

     (10) Notwithstanding any other provision of this Agreement, the number of
different maturity dates for all Bankers' Acceptances and BA Equivalent Notes
outstanding at any time under Tranches 1, 2 and 3 shall not exceed 100 less the
number of LIBOR Periods for all LIBOR Loans outstanding at such time under such
Tranches, and there shall not at any time be more than that number of different
maturity dates for all Bankers' Acceptances and BA Equivalent Notes outstanding
at that time under the Cdn. Operating Line as may have been agreed to prior to
such time by the Cdn. Borrower and the Cdn. Operating Lender.

     (11) For the purpose of calculating the undisbursed Credit or any
applicable Undisbursed Commitment or Undisbursed Tranche and for any other
relevant provision of this Agreement, the amount of Accommodation constituted
by any Bankers' Acceptance or BA Equivalent Note shall be the face amount of
such Bankers' Acceptance or BA Equivalent Note, as the case may be.

1.026   LETTERS OF CREDIT

     (1) Each Letter of Credit requested by the Cdn. Borrower shall be made
available under the LC Line by the Cdn. LC Issuer on behalf of the Cdn. LC
Lenders and each Letter of Credit requested by the U.S. Borrower shall be made
available under the LC Line by the U.S. LC Issuer on behalf of the U.S. LC
Lenders.  Each Letter of Credit (including all documents and instruments
required to be presented under such Letter of Credit) shall be satisfactory in
form and substance to the applicable LC Issuer.  No Letter of Credit shall be
issued (or shall be renewable) for a term in excess of one year or for a term
which would extend beyond the Maturity Date, or shall require payment in any
currency other than Cdn. Dollars or U.S. Dollars in the case of a Letter of
Credit issued by the Cdn. LC Issuer or U.S. Dollars in the case of a Letter of
Credit issued by the U.S. LC Issuer.

     (2) As a condition of the issuance or renewal of any Letter of Credit, the
Cdn. Borrower or the U.S. Borrower, as the case may be, shall pay to the
applicable LC Issuer and shall pay to the Administrative Agent for the account
of the applicable the applicable LC Lenders on the date of such issuance or
renewal the related fees specified in Section 3.10 and shall, if requested by
such LC Issuer, execute and deliver to such LC Issuer such LC Issuer's then
current standard form letter of credit application, reimbursement and
indemnification agreements (all of which shall constitute Credit Documents).
The Cdn. Borrower or the U.S. Borrower, as the case may be, shall also pay to
such LC Issuer its customary cable charges and other administrative charges in
respect of the issue of such Letter of Credit, the amendment or transfer of
such Letter of Credit, each renewal of such Letter of Credit and each drawing
made under such Letter of Credit.


   69
                                                                  SECTION 2.06

                                - 61 -

     (3) The Cdn. Borrower or the U.S. Borrower, as the case may be, will pay
to the applicable LC Issuer sufficient funds in the currency of each Letter of
Credit, either immediately on demand by such LC Issuer, to reimburse such LC
Issuer for any payment made by it pursuant to such Letter of Credit, or at the
option of such LC Issuer by prior written notice to the applicable Borrower, on
or prior to the date on which any payment is to be made by such LC Issuer
pursuant to such Letter of Credit, to fund such payment by such LC Issuer.  If
a Borrower does not make any payment required by the preceding sentence, from
the proceeds of Accommodation obtained under this Agreement or otherwise, the
applicable LC Issuer may (but shall not be obliged to), without receipt of a
Notice of Borrowing, irrespective of whether any applicable conditions
precedent under this Agreement have been met and without waiver of the Default
or the Event of Default constituted by such Borrower's failure to make such
required payment, make a Prime Rate Loan or U.S. Base Rate Loan to the Cdn.
Borrower (in the case of the Cdn. LC Issuer) or a U.S. Reference Rate Loan to
the U.S. Borrower (in the case of the U.S. LC Issuer), as the case may be, in
the amount and currency of such required payment, and shall promptly give
notice of such Loan to the applicable Borrower and the Administrative Agent
(which shall promptly give similar notice to the other LC Lenders).  Each
Borrower agrees to accept each such Loan and irrevocably authorizes and directs
the applicable LC Issuer to apply the proceeds of each such Loan in payment of
the liability of such Borrower with respect to such required payment.
Notwithstanding any other provision of this Agreement, all Loans made as
contemplated by this subsection shall be payable on demand by the
Administrative Agent or the applicable LC Issuer.

     (4) Each of the Cdn. LC Lenders, other than the Cdn. LC Issuer, agrees
that it will purchase from the Cdn. LC Issuer, and the Cdn. LC Issuer shall
sell to such Lenders, for cash, at par, without representation or warranty from
or Recourse Against the Cdn. LC Issuer and irrespective of whether a Default or
Event of Default has occurred and is continuing at the relevant time and
irrespective of whether the Credit has been terminated or any acceleration of
outstanding Accommodation has occurred pursuant to Section 9.02, pro rata based
on their respective Cdn. LC Commitments, an undivided interest in any Prime
Rate Loan or U.S. Base Rate Loan made by the Cdn. LC Issuer pursuant to
subsection 2.06(3), immediately upon such Prime Rate Loan or U.S. Base Rate
Loan being made, or if no such Loan has then been made an undivided interest in
any reimbursement right of the Cdn. LC Issuer from the Cdn. Borrower pursuant
to subsection 2.06(3) for any payment made by the Cdn. LC Issuer pursuant to a
Letter of Credit immediately on request by the Cdn. LC Issuer.  Each of the
U.S. LC Lenders, other than the U.S. LC Issuer, agrees that it will purchase
from the U.S. LC Issuer, and the U.S. LC Issuer shall sell to such Lenders, for
cash, at par, without representation or warranty from or Recourse Against the
U.S. LC Issuer and irrespective of whether a Default or Event of Default has
occurred and is continuing at the relevant time and irrespective of whether the
Credit has been terminated or any acceleration of outstanding Accommodation has
occurred pursuant to Section 9.02, pro rata based on their respective U.S. LC
Commitments, an undivided interest in any U.S. Reference Rate Loan made by the
U.S. LC Issuer pursuant to


   70
                                                                  SECTION 2.06

                                - 62 -


subsection 2.06(3), immediately upon such U.S. Reference Rate Loan being made,
or if no such Loan has then been made an undivided interest in any
reimbursement right of the U.S. LC Issuer from the U.S. Borrower pursuant to
subsection 2.06(3) for any payment made by the U.S. LC Issuer pursuant to a
Letter of Credit immediately on request by the U.S. LC Issuer.  The
Administrative Agent, upon consultation with the applicable Lenders, shall have
the power to settle any documentation required to evidence any such purchase
and, if deemed advisable by the Administrative Agent, to execute any document
as attorney for any Lender in order to complete any such purchase.  The
Borrowers and the Lenders acknowledge that the foregoing arrangements are to be
settled by the applicable LC Issuer and the applicable LC Lenders among
themselves, and the Borrowers expressly consent to the foregoing arrangements
among the LC Issuers and the LC Lenders.

     (5) If any Letter of Credit is outstanding on the Maturity Date or at any
time that an Event of Default occurs or that a domestic or foreign court issues
any judgement or order restricting or prohibiting payment by the applicable LC
Issuer under such Letter of Credit or extending the liability of such LC Issuer
to make payment under such Letter of Credit beyond the expiry date specified in
such Letter of Credit, the applicable Borrower shall immediately, in the case
of any Letter of Credit outstanding on the Maturity Date, and otherwise
immediately upon demand by the Administrative Agent, pay to the Administrative
Agent, for the account of such LC Issuer, funds in the currency of such Letter
of Credit and in the amount of the Accommodation constituted by such Letter of
Credit.  Such funds (together with interest on such funds) shall be held by the
Administrative Agent, subject to Section 9.03, for payment of the liability of
such Borrower pursuant to subsection 2.06(3) or otherwise in respect of such
Letter of Credit so long as such LC Issuer has or may in any circumstance have
any liability under such Letter of Credit, and shall bear interest for such
terms as are selected from time to time by the Administrative Agent at the
wholesale money market rate of the Administrative Agent for deposits of similar
currency, amounts and maturities.  Any balance of such funds and interest
remaining at such time as the applicable LC Issuer does not have and may never
have any liability under such Letter of Credit shall nevertheless continue to
be held by the Administrative Agent, if and so long as any Event of Default is
continuing, as security for the remaining liabilities of such Borrower under
the Credit Documents.

     (6) Each Borrower agrees that neither LC Issuer nor any LC Lender nor any
of their respective officers, directors or correspondents shall assume
liability for, or be responsible for, the use which may be made of any Letter
of Credit; any acts or omissions of the beneficiary of any Letter of Credit
including the application of any payment made to such beneficiary; the form,
validity, sufficiency, correctness, genuineness or legal effect of any document
or instrument relating to any Letter of Credit, even if such document or
instrument should in fact prove to be in any respect invalid, insufficient,
inaccurate, fraudulent or forged; payment by an LC Issuer of any draft which
does not comply with the terms of any Letter of Credit, unless such payment
results from the gross negligence or wilful misconduct of such LC Issuer; the
failure of any


   71
                                                                  SECTION 2.06

                                - 63 -


document or instrument to bear any reference or adequate reference to any
Letter of Credit; any failure to note the amount of any draft on any Letter of
Credit or on any related document or instrument; any failure of the beneficiary
of any Letter of Credit to meet the obligations of such beneficiary to any
Borrower or any other Person; any errors, inaccuracies, omissions,
interruptions or delays in transmission or delivery of any messages, directions
or correspondence by mail, facsimile or otherwise, whether or not they are in
cipher; any inaccuracies in the translation of any messages, directions or
correspondence or for errors in the interpretation of any technical terms; or
any failure by an LC Issuer to make payment under any Letter of Credit as a
result of any law, control or restriction rightfully or wrongfully exercised or
imposed by any Governmental Authority or as a result of any other cause beyond
the control of such LC Issuer or its officers, directors or correspondents.

     (7) The obligations of the Borrowers under this Section with respect to
any Letter of Credit shall be absolute, unconditional and irrevocable, and
shall be performed strictly in accordance with the terms of this Agreement
under all circumstances including, without limitation, any matter referred to
in subsection 2.06(5); any invalidity of any obligation secured by any Letter
of Credit; any incapacity, disability or lack or limitation of status or of
power of a Borrower or the beneficiary of any Letter of Credit; any lack of
validity or enforceability of any Letter of Credit; the existence of any claim,
set-off, defense or other right which a Borrower or any other Restricted Party
or any of their Affiliates may have at any time against an LC Issuer, the
Administrative Agent, the Other Agents, any Lender, the beneficiary of any
Letter of Credit or any other Person; or any breach of contract or other
dispute between a Borrower or any other Restricted Party or any of their
Affiliates and an LC Issuer, the Administrative Agent, the Other Agents, any
Lender, the beneficiary of any Letter of Credit or any other Person.

     (8) An LC Issuer may accept as complying with the terms of any Letter of
Credit any document or instrument required by such Letter of Credit to be
completed, signed, presented or delivered by or on behalf of any beneficiary
under such Letter of Credit which


   72
                                                                  SECTION 2.06

                                - 64 -


has been completed, signed, presented or delivered by a receiver, trustee in
bankruptcy, assignee for the benefit of creditors, secured party or other like
person believed in good faith by such LC Issuer to be lawfully entitled to the
property of such beneficiary, and such LC Issuer may make payments under such
Letter of Credit to such Person.  The provisions of this subsection are for the
sole benefit of the LC Issuers, the Administrative Agent and the Lenders, and
may not be relied on by any other Person.

     (9) Each Letter of Credit, except as specifically provided in such Letter
of Credit, and subject to any provision of this Agreement to the contrary,
shall be subject to the Uniform Customs and Practice for Documentary Credits of
the International Chamber of Commerce current at the time of issuance of such
Letter of Credit.

     (10) For the purpose of calculating the Undisbursed Credit, any applicable
Undisbursed Commitment or the Undisbursed LC Line and for any other relevant
provision of this Agreement, the amount of Accommodation constituted by any
Letter of Credit shall be the maximum amount in U.S. Dollars (for which purpose
any amount payable in a currency other than U.S. Dollars shall be deemed to be
the Equivalent Amount of U.S. Dollars) which the applicable LC Issuer may in
all circumstances be required to pay pursuant to the terms of such Letter of
Credit.  In addition, for the purpose of calculating the principal amount of
outstanding Accommodation that has been made available at any time by any LC
Lender (including any LC Issuer in its capacity as an LC Lender), each Letter
of Credit issued by the Cdn. LC Issuer shall be deemed to have been made
available by the Cdn. LC Lenders pro rata based on their respective Cdn. LC
Commitments and each Letter of Credit issued by the U.S. LC Issuer shall be
deemed to have been made available by the U.S. LC Lenders pro rata based on
their respective U.S. LC Commitments.


1.027   OVERDRAFTS UNDER THE OPERATING LINES

     (1) The Cdn. Borrower shall open a Cdn. Dollar operating account and a
U.S. Dollar operating account with the Cdn. Operating Lender.  Subject to the
limitations set forth in this Agreement, the Cdn. Borrower shall be entitled to
obtain Prime Rate Loans under the Cdn. Operating Line by way of overdraft in
such Cdn. Dollar operating account and to obtain U.S. Base Rate Loans by way of
overdraft under the Cdn. Operating Line in such U.S. Dollar operating account.
The aggregate amount of all cheques drawn on such Cdn. Dollar operating account
and honoured by the Cdn. Operating Lender on each day together with the
aggregate amount of all other withdrawals debited to such account during such
day, net of the credit balance of such account at the beginning of such day (if
any) and all deposits or credits to such account during such day, shall be
deemed to be a Prime Rate Loan by way of overdraft made by the Cdn. Operating
Lender to the Cdn. Borrower under the Cdn. Operating Line on such day.  The
aggregate amount of all cheques drawn on such U.S. Dollar operating account and
honoured by the Cdn. Operating Lender on each day together with the aggregate
amount of all other

                                                                  SECTION 2.07

                                - 65 -


withdrawals debited to such account during such day, net of the credit balance
of such account at the beginning of such day (if any) and all deposits or
credits to such account during such day, shall be deemed to be a U.S. Base Rate
Loan by way of overdraft made by the Cdn. Operating Lender to the Cdn. Borrower
under the Cdn. Operating Line on such day.

     (2) The U.S. Borrower shall open a U.S. Dollar operating account with each
of the U.S. Operating Lenders.  Subject to the limitations set forth in this
Agreement, the U.S. Borrower shall be entitled to obtain U.S. Reference Rate
Loans by way of overdraft under each of the U.S. Operating Lines in such U.S.
Dollar operating account maintained with the applicable U.S. Operating Lender.

account and honoured by the applicable U.S. Operating Lender on each day
together with the aggregate amount of all other withdrawals debited to such
account during such day, net of the credit balance of such account at the
beginning of such day (if any) and all deposits or credits to such account
during such day, shall be deemed to be a U.S. Reference Rate Loan by way of
overdraft made by such U.S. Operating Lender to the U.S. Borrower under the
U.S. Operating Line from such U.S. Lender on such day.


1.028   LENDERS' ACCOUNTS

     (1) Each Lender will open and maintain an account or accounts evidencing
(i) the indebtedness and obligations of the applicable Borrower to such Lender
under this Agreement in respect of outstanding Accommodation and accrued
interest, fees and other amounts payable under this Agreement, (ii) the types
of Accommodation outstanding from such Lender to the applicable Borrower from
time to time and the date or dates on which such Accommodation was made
available to such Borrower, and (iii) the amounts from time to time paid by
such Borrower to such Lender under this Agreement on account of Accommodation,
interest, fees and other amounts.  Each Borrower acknowledges, confirms and
agrees that all such accounts kept by the Lenders will constitute prima facie
evidence of the matters referred to above; provided, however, that the failure
of any Lender to make any entry or recording in any such account shall not
limit or otherwise affect the obligations of any Borrower under this Agreement
or with respect to any Accommodation, interest, fees or other amounts owed to
such Lender.

     (2) The Administrative Agent will maintain a register (the "REGISTRY OF
COMMITMENTS") on which the Administrative Agent will record the nature and
amount of all Commitments from time to time of each of the Lenders, the
Accommodation made from time to time by each of the Lenders (other than the
Operating Lenders) and each repayment in respect of the principal amount of
such Accommodation of each such Lender (other than the Operating Lenders).  The
Administrative Agent will open the Registry of Commitments on the date of this
Agreement and will enter into and record on the Registry of Commitments on such
date the Commitments of all of the Lenders as set forth in Schedules 1 and 27
and the Commitments of each of the Operating Lenders on the date of this
Agreement.  Thereafter the Administrative



   74
                                                                  SECTION 2.08

                                - 66 -


Agent will enter into and record on the Registry of Commitments any and all
changes to the Commitments of any one or more Lenders made pursuant to the
provisions of this Agreement, the addition of new Lenders and the removal of
Lenders as a result of assignments and transfers made pursuant to Section 12.01
and all assignments and transfers of Commitments made pursuant to Section
12.01.  Failure to make any such recordation, or any error in such recordation
shall not affect either of the Borrower's obligations in respect of any
Accommodation or otherwise under or in respect of any Credit Document.  The
transfer of any Commitment of any Lender and the rights to the principal of,
interest on and fees with respect to any Accommodation outstanding pursuant to
such Commitment shall not be effective as between any Borrower, the
Administrative Agent and the transferee until such transfer is recorded on the
Registry of Commitments.  The registration of any assignment or transfer of any
Commitment and Accommodation outstanding thereunder shall be recorded by the
Administrative Agent on the Registry of Commitments only upon the acceptance by
the Administrative Agent of a properly executed and delivered Undertaking and a
properly executed and delivered assignment and assumption agreement pursuant to
paragraph 12.01(b)(iii).  The Borrowers agree to indemnify and save harmless
the Administrative Agent from and against any losses, claims, damages and
liabilities of whatsoever nature which may be imposed on, served against or
incurred by the Administrative Agent in performing its duties under this
subsection.  In the event of any conflict between the Registry of Commitments
and any account maintained by any Lender pursuant to subsection 2.08(1), the
Registry of Commitments shall prevail.  Each of the Borrower's designates the
Administrative Agent to also serve as such Borrower's agent solely for the
purposes of this subsection for the purpose of maintaining the Registry of
Commitments.

1.029   LIBOR LOANS

     (1) Each LIBOR Loan shall be U.S. $100,000 or any whole multiple of U.S.
$100,000, and the aggregate amount of all LIBOR Loans advanced pursuant to any
Notice of Borrowing under any Tranche or Tranches shall not be less than the
applicable amounts set forth in Schedule 12 with respect to such Tranche or
Tranches.

     (2) The aggregate face amount of LIBOR Loans from a Lender on any
Borrowing Date shall be determined by the Administrative Agent based upon the
amounts of the respective Commitments under the Tranche or Tranches under which
such LIBOR Loans are being made, except that, if the amount of any LIBOR Loan
to be made by a Lender, determined as provided for above, would not be U.S.
$100,000 or a whole multiple of U.S. $100,000, the Administrative Agent in its
sole discretion may increase such face amount to the nearest whole multiple of
U.S. $100,000 or may reduce such face amount to the nearest whole multiple of
U.S. $100,000.


   75
                                                                  SECTION 2.10

1.201   OPTIONAL REDUCTION OF LIMIT OF TRANCHES

     The Cdn. Borrower shall have the right at any time and from time to time,
on behalf of the Borrowers, upon not less than 30 days prior written notice to
the Administrative Agent, to permanently reduce the limit of any Tranche
(provided that in the case of any of Tranches 1, 2 and 3 such reduction must be
made pro rata among all such Tranches then in effect) (and accordingly the
limit of each Commitment under such Tranche) by all or any part of the
Undisbursed Tranche of such Tranche; provided, however, that no such reduction
of the limit of a Tranche shall be in (x) an aggregate amount less than U.S.
$1,000,000 (or the entire amount of such Tranche if lesser), or (y) an
aggregate amount in excess of U.S. $1,000,000 which is not a whole multiple of
U.S. $100,000 (or the entire amount of such Tranche if lesser).

           by the Cdn. LC Issuer, a Letter of Credit issued by the Cdn.  LC

           Operating Lender;

      (d)  Pre-existing LIBOR Loans:  Each Pre-existing LIBOR Loan shall be,
           and shall be deemed for all purposes to be, a LIBOR Loan made by the

           to the applicable Borrower indicated in Schedule 8, and outstanding,

                                - 69 -


existing Accommodation Lender for, and agrees to pay to each such Pre-existing
Accommodation Lender on the first interest payment date under Article Three
following the Closing Date, all interest which is, at the Closing Date, accrued
and unpaid under the Existing Philip Bank Credit Agreement in respect of the

Issuer were deemed to be reference to the applicable Pre-existing Accommodation
Lender and, with respect to the Cdn. Operating Lender and each U.S. Operating
Lender in their capacities as Pre-existing Accommodation Lenders, reference in
such Section to the LC Line was deemed to be reference to the Cdn. Operating
Line or the applicable U.S. Operating Line, as the case may be.  For greater
certainty, Pre-existing LCs from the Cdn. Operating Lender and the U.S.
Operating Lenders may not be renewed but will, on expiry, be replaced by a new
Letter of Credit issued by the applicable LC Issuer under the LC Line.  The
Cdn. Borrower, the Cdn. Operating Lender, the U.S. Operating Lenders and the LC
Lenders will co-operate with a view to replacing all Pre-existing LCs from the
Cdn. Operating Lender and the U.S. Operating Lenders as soon as possible
following the Closing Date (in a manner which will not cause duplication of
Letters of Credit or inconvenience to the Borrowers) with new Letters of Credit
issued by the LC Issuers under the LC Line.

     (4) Notwithstanding any other provision of this Agreement which would
require that Borrowings be made on a pro rata basis by any Lenders or group or
groups of Lenders, (a) each of the Pre-existing Accommodation Lenders, subject
to subsection 2.11(3), will continue to hold after the Closing Date, until
their respective maturity or expiry dates, all Pre-existing Accommodation held
by such Lenders on the Closing Date, (b) subject to clause (c) of this
subsection and to the limit of each Lender's applicable Commitment, all new
Borrowings under this Agreement will be made pro rata by the applicable Lenders
or group or groups of Lenders as otherwise required under this Agreement
without regard to the Pre-existing Accommodation held by any such Lenders, and
(c) the Administrative Agent may from time to time in its discretion adjust the
manner in which any Lenders or group or groups of Lenders share in any new
Borrowings under this Agreement having regard to the outstanding Pre-existing
Accommodation at such time and with a view to ensuring that all applicable
Lenders or groups of Lenders hold outstanding Accommodation as soon as possible
after the Closing Date on a pro rata basis as contemplated under the other
provisions of this Agreement.

           the expiry of any LIBOR Period with respect to any outstanding LIBOR 
           Loan, such LIBOR Loan shall be automatically converted on the expiry 
           of such existing LIBOR Period to:

              (i)  a U.S. Base Rate Loan under the same Tranche as the Tranche
                   under which such LIBOR Loan was outstanding in the case of
                   any LIBOR Loan under Tranche 1 or the Cdn.  Operating Line
                   or any LIBOR Loan from a Cdn. Cross Border Lender under
                   Tranche 2; or

              (ii) a U.S. Reference Rate Loan under the same Tranche as the
                   Tranche under which such LIBOR Loan was outstanding in the
                   case of any LIBOR Loan under Tranche 3 or either U.S.
                   Operating Line or any LIBOR Loan from a U.S.  Cross Border
                   Lender under Tranche 2.

      (b)  Any LIBOR Period that begins on the last Business Day in a calendar
           month, or on a day for which there is no numerically corresponding
           day in the calendar month in which such LIBOR Period would otherwise
           end, shall end on the last Business Day in the calendar month in
           which such LIBOR Period would otherwise end.

      (c)  If any LIBOR Period would otherwise end on a day which is not a
           Business Day, such LIBOR Period shall end on the next succeeding
           Business Day, provided, however, that if such next succeeding
           Business Day falls in the next calendar month, such LIBOR Period
           shall end on the next preceding Business Day.

      (d)  No LIBOR Period may extend beyond the Maturity Date.

      (e)  The number of different LIBOR Periods for all LIBOR Loans
           outstanding at any time under Tranches 1, 2 and 3 shall not exceed
           100 less the number of maturity dates for all Bankers' Acceptances
           and BA Equivalent Notes outstanding at that time under such
           Tranches, and there shall not at any time be more than that number
           of different LIBOR Periods for all LIBOR Loans outstanding at that
           time under an Operating Line as may have been agreed to prior to
           such time by the applicable Borrower and Operating Lender under such
           Operating Line.


1.036   FAILURE OF THE LIBOR

     If at any time a Lender (or in the case of clause (i) below and any Lender
under Tranche 1, 2 or 3, the Administrative Agent) shall determine (which
determination shall be conclusive and binding) that by reason of circumstances
affecting the London interbank market or any other relevant financial market or
the position of such Lender (or in the case of clause (i) below and


   82
                                                                  SECTION 3.06

                                - 74 -


any Lender under Tranche 1, 2 or 3, the Administrative Agent) in any such
market (i) adequate and reasonable means do not exist for ascertaining the
LIBOR to be applicable during any LIBOR Period, or (ii) the LIBOR does not
adequately reflect the effective cost to such Lender of the funds to be used by
it to make or continue the applicable LIBOR Loan for any LIBOR Period, or (iii)
U.S. Dollars in the amount of the applicable LIBOR Loan are not readily
available to such Lender for any LIBOR Period in the London interbank market,
then such Lender shall give notice of such event (by telephone to be confirmed
the same day in writing) or by facsimile to the applicable Borrower and the
Administrative Agent (which shall promptly give a copy of such notice to the
other Lenders).  On the last day of the LIBOR Period then applicable to each
such LIBOR Loan, the interest on each LIBOR Loan then outstanding from such
Lender as a LIBOR Loan shall cease to be calculated under this Agreement on the
basis of the LIBOR and shall commence to be calculated under this Agreement on
the basis of:

      (a)  the U.S. Base Rate in the case of any such LIBOR Loan under Tranche
           1 or the Cdn. Operating Line or any such LIBOR Loan from a Cdn.
           Cross Border Lender under Tranche 2; or

      (b)  the U.S. Reference Rate in the case of any such LIBOR Loan under
           Tranche 3 or either U.S. Operating Line or any such LIBOR Loan from
           a U.S. Cross Border Lender under Tranche 2.

Any Notice of Borrowing which has been delivered to such Lender requesting a
LIBOR Loan on a Borrowing Date on or subsequent to such notification date shall
be deemed to request:

      (a)  a U.S. Base Rate Loan in the same amount in the case of any such
           LIBOR Loan under Tranche 1 or the Cdn. Operating Line or any such
           LIBOR Loan from a Cdn. Cross Border Lender under Tranche 2; or

      (b)  a U.S. Reference Rate Loan in the same amount in the case of any
           such LIBOR Loan under Tranche 3 or either U.S. Operating Line or any
           such LIBOR Loan from a U.S. Cross Border Lender under Tranche 2.

The Borrowers shall not be entitled to obtain any LIBOR Loan from such Lender
so long as any such condition shall continue to exist, and any Loan that would
otherwise have been made by such Lender as a LIBOR Loan shall instead be made
by such Lender as:

      (a)  a U.S. Base Rate Loan in the same amount in the case of any such
           LIBOR Loan under Tranche 1 or the Cdn. Operating Line or any such
           LIBOR Loan from a Cdn. Cross Border Lender under Tranche 2; or


   83
                                                                  SECTION 3.06

                                - 75 -


      (b)  a U.S. Reference Rate Loan in the same amount in the case of any
           such LIBOR Loan under Tranche 3 or either U.S. Operating Line or any
           such LIBOR Loan from a U.S. Cross Border Lender under Tranche 2.


1.037   DETERMINATION OF RATES AND BASIS OF CALCULATION OF INTEREST

     (1) The BA Discount Rate, Federal Funds Rate, LIBOR, Prime Rate, U.S. Base
Rate and U.S. Reference Rate shall be determined by the Administrative Agent
whenever such determination is required for any purpose of this Agreement, and
such determination by the Administrative Agent, and each determination by a
Lender of a rate to be notified to the Administrative Agent pursuant to the
definition of "BA Discount Rate" in Section 1.01, or in connection with any
rates or fees applicable to any Operating Line, shall be prima facie evidence
of such rate.  The Administrative Agent shall, at the request of either
Borrower, promptly notify such Borrower of any of the rates notified to the
Administrative Agent by the Lenders with respect to the "BA Discount Rate" or
any Operating Line.

     (2) All interest in respect of Prime Rate Loans shall be payable in Cdn.
Dollars and all interest in respect of U.S. Base Rate Loans, U.S. Reference
Rate Loans and LIBOR Loans shall be payable in U.S. Dollars.

shall be included and the last day of such period shall be excluded.


1.038   MAXIMUM RETURN

     Notwithstanding any provision of this Agreement, in no event shall the
aggregate "interest" (as defined in section 347 of the Criminal Code (Canada))
payable under this Agreement exceed the effective annual rate of interest on
the "credit advanced" (as defined in that section) under this Agreement
lawfully permitted by that section, nor shall the interest payable under this
Agreement exceed the rate of interest which may be lawfully charged under this
Agreement by any other Applicable Law having application to interest payable
under this Agreement, and, if any payment, collection or demand pursuant to
this Agreement in respect of "interest" (as defined in that section) or under
any such other Applicable Law is determined to be contrary to the provisions of
that section or such other Applicable Law, such payment, collection or demand
shall be deemed to have been made by mutual mistake of the applicable Borrower
and the applicable Lender and the amount of such payment or collection shall be
refunded to such Borrower.  For the purposes of this Agreement, the effective
annual rate of interest shall be determined in accordance with generally
accepted actuarial practices and principles over the term of the Credit and, in
the event of dispute, a certificate of a Fellow of the


   84
                                                                  SECTION 3.08

1.041   OPTIONAL REPAYMENT 


     (1) Each Borrower shall have the right to repay from time to time on any
Business Day (an "OPTIONAL REPAYMENT DATE") any Accommodation outstanding to
it, without premium but subject to Section 5.05, on the terms and conditions
that, except in the case of any repayments under an Operating Line which shall
be subject to arrangements from time to time entered into between the Cdn.
Borrower and the Cdn. Operating Lender and between the U.S. Borrower and each
of the U.S. Operating Lenders:

      (a)  such Borrower shall give to the Administrative Agent not less than 3
           Business Days' irrevocable prior written notice (other than with
           respect to repayments by way of renewal or conversions of
           Accommodation which shall require the applicable notice for
           Borrowings referred to in Section 2.04) specifying the amount and
           the type of Accommodation to be repaid (which shall be the same type
           from each applicable Lender), the Tranche under which such
           Accommodation is outstanding, and the applicable Optional Repayment
           Date;

      (b)  each repayment of Accommodation pursuant to this subsection shall be
           allocated (as to both amount, type, and applicable maturity, of
           Accommodation) to the Lenders under the applicable Tranche (or in
           the case of Tranches 1, 2 and 3 under all of such Tranches) having
           Commitments under such Tranche or Tranches, as the case may be, to
           the Borrower making the repayment on a Rateable basis;

      (c)  the aggregate U.S. Dollar Amount of Accommodation repaid pursuant to
           this subsection at any time shall be not less than U.S.  $10,000,000
           or an amount in excess of U.S. $10,000,000 which is a whole multiple
           of U.S. $100,000 (or all Accommodation then outstanding under the
           applicable Tranche, if lesser);

      (d)  no repayment of any LIBOR Loan shall be made otherwise than upon the
           expiration of a LIBOR Period applicable to such LIBOR Loan and no
           repayment of any Bankers' Acceptance or BA Equivalent Note shall be
           made otherwise than on the maturity date of such Bankers' Acceptance
           or BA Equivalent Note, as the case may be; and

      (e)  on the applicable Optional Repayment Date such Borrower shall repay
           outstanding Accommodation in accordance with the notice given
           pursuant to clause (a) above and for such purpose shall pay to the
           Administrative Agent the


   88
                                                                  SECTION 4.01

                                - 80 -

          
           amount of any Loans, Bankers' Acceptances and BA Equivalent Notes 
           included in such repayment together with all interest and other 
           fees and other amounts accrued and unpaid under this Agreement, and 
           any amounts payable under Section 5.05, with respect to any such 
           Accommodation that is repaid.  For greater certainty, however, a 
           repayment of outstanding Accommodation under a Tranche pursuant to 
           this subsection shall not reduce the limit of such Tranche then in 
           effect and additional Accommodation may from time to time be 
           obtained by the Borrowers under such Tranche in accordance with and
           subject to the applicable provisions of this Agreement.

     (2) The Administrative Agent shall promptly notify the applicable Lenders
of any proposed repayment of Accommodation pursuant to subsection 4.01(1) and
the amount and type of such Accommodation to be repaid to each such Lender.
The amount received by the Administrative Agent in respect of any Loans,
Bankers' Acceptances and BA Equivalent Notes included in the repayment shall be
distributed by the Administrative Agent to the applicable Lenders on a Rateable
basis and any accrued and unpaid interest, fees and other amounts (other than
amounts payable under Section 5.05 which shall be for the account of the Lender
entitled to the same) received by the Administrative Agent with respect thereto
shall be distributed by the Administrative Agent to the applicable Lenders on
the basis of their respective entitlements thereto.


1.042   MANDATORY REPAYMENT

     Each Borrower shall repay all Accommodation outstanding to it, together
with all accrued interest, fees and other amounts then unpaid by it with
respect to such Accommodation and the Credit, on the Maturity Date, and the
Credit and all of the Commitments shall be automatically terminated on the
Maturity Date.

1.043   SURPLUS ADDITIONAL DEBT AND COMMITMENTS

      If:

      (a)  the Cdn. Borrower does not have an Investment Grade Rating on the
           date that any Surplus Additional Debt and Commitments is assumed,
           created or otherwise arises; or

      (b)  the Cdn. Borrower has an Investment Grade Rating on the date that
           any Surplus Additional Debt and Commitments is assumed, created or
           otherwise arises but loses such Investment Grade Rating within the
           period of 90 days following such date;


   89
                                                                  SECTION 4.03

                                - 81 -


(the date on which such Surplus Additional Debt and Commitments is assumed,
created or otherwise arises as described in subsection (a) of this Section or
the date on which the Cdn. Borrower loses its Investment Grade Rating as
described in subsection (b) of this Section, whichever is applicable, being
referred to as the "ADDITIONAL DEBT CREDIT REDUCTION DATE"), the limit of the
Credit (on a pro rata basis among Tranches 1, 2 and 3 on the basis of the
aggregate Commitments under such Tranches until the limit of such Tranches is
reduced to 0 and thereafter on a pro rata basis among the remaining Tranches on
the basis of the aggregate Commitments under such Tranches), effective on such
Additional Debt Credit Reduction Date, will be permanently reduced by an amount
equal to 75% of the amount of such Surplus Additional Debt and Commitments so
assumed, created or otherwise arising and each of the Borrowers, within 5
Business Days of any such date referred to in subsection (a) of this Section
and within 15 Business Days of any such date referred to in subsection (b) of
this Section, will repay sufficient Accommodation under the affected Tranches
so that, after giving effect to such repayment and any concurrent repayments
made by the other Borrower, the U.S. Dollar Amount of the Accommodation then
outstanding under each such Tranche does not exceed the reduced limit of such
Tranche.


1.044    EXCESS PROPERTY SALES PROCEEDS

     (1) On the Business Day following the date of the closing of any
Disposition, the Borrowers shall pay to the Administrative Agent (to be applied
on a Rateable basis to the Lenders under Tranches 1, 2 and 3 until all
Accommodation under such Tranches has been repaid and then on Rateable basis to
the Lenders under the remaining Tranches) an amount equal to that portion, if
any, of the Deemed Proceeds of Disposition Amount relative to such Disposition
which was not Reinvested in the Restricted Parties on the date of the closing
of such Disposition (provided that no such repayment shall reduce the limit of
the Credit).

     (2) On the Anniversary of each Disposition the limit of the Credit (on a
pro rata basis among Tranches 1, 2 and 3 until the limit of such Tranches is
reduced to 0 and thereafter on a pro rata basis among the remaining Tranches)
will be permanently reduced by an amount equal to the Permanent Disposition
Reduction Amount, if any, relative to such Disposition and each of the
Borrowers will repay sufficient Accommodation under the affected Tranches so
that, after giving effect to such repayment and any concurrent repayments made
by the other Borrower, the U.S. Dollar Amount of the Accommodation then
outstanding under each such Tranche does not exceed the reduced limit of such
Tranche.


1.045   CURRENCY FLUCTUATIONS

     If at any time the U.S. Dollar Amount of the Accommodation then
outstanding under any Tranche exceeds the limit of such Tranche then in effect,
each Borrower shall repay in accordance with subsection 4.01(1) within 10 days
of receipt of a demand for such repayment from the Administrative Agent such
Accommodation outstanding to it so that, after giving effect


   90
                                                                  SECTION 4.05

                                - 82 -

to such repayment and any concurrent repayments made by the other Borrower, the
U.S. Dollar Amount of the Accommodation then outstanding under such Tranche
does not exceed the limit of such Tranche then in effect.


1.046   ILLEGALITY

     Notwithstanding any other provision of this Agreement, if the making or
continuation of any type of Accommodation by any Lender, or the receipt by any
Lender of any amount payable under this Agreement by a Borrower in respect of
any such Accommodation, shall have been made unlawful or impracticable due to
compliance by such Lender in good faith (as determined by such Lender, which
determination shall be conclusive and binding) with any Applicable Law or with
any request or directive (whether or not having the force of law) by any
Governmental Authority (including any central bank, Superintendent of Financial
Institutions or other comparable authority or agency) having jurisdiction, such
Lender shall give notice of such event to such Borrower and the Administrative
Agent (which shall promptly give similar notice to the other Lenders) and:

      (a)  in the case of a LIBOR Loan, on the last day of the LIBOR Period
           then applicable to such LIBOR Loan, or on such earlier date as may
           be required by such event, the interest on such Loan shall cease to
           be calculated under this Agreement on the basis of the LIBOR and
           shall commence to be calculated under this Agreement on the basis
           of:

           (i)  the U.S. Base Rate in the case of any such LIBOR Loan under
                Tranche 1, the Cdn. Operating Line or any such LIBOR Loan
                from a Cdn. Cross Border Lender under Tranche 2 and provided
                that such Lender is then obliged to make U.S. Base Rate
                Loans under this Agreement; or

           (ii) the U.S. Reference Rate in the case of any such LIBOR Loan
                under Tranche 3, or any such LIBOR Loan under either U.S.
                Operating Line or any such LIBOR Loan from a U.S. Cross
                Border Lender under Tranche 2;

      (b)  in the case of a U.S. Base Rate Loan or a U.S. Reference Rate Loan,
           on such date thereafter as may be required by such Lender, the
           interest on such Loan shall cease to be calculated under this
           Agreement on the basis of the U.S. Base Rate or the U.S. Reference
           Rate, as the case may be, and shall commence to be calculated under
           this Agreement on the basis of the LIBOR (and such Borrower shall
           select the term of each applicable LIBOR Period in accordance with
           Section 3.05) (provided that such Lender is then obliged to make
           LIBOR Loans under this Agreement); and


   91
                                                                  SECTION 4.06

                                - 83 -


      (c)  in any other case, such Borrower shall repay to such Lender all
           Accommodation of such type on such date thereafter as may be
           required by such Lender, and for such purpose shall be entitled to
           obtain from such Lender any type of Accommodation that such Lender
           is then obliged to make available under this Agreement in a U.S.
           Dollar Amount equal to the U.S. Dollar Amount of the Accommodation
           required to be repaid by it.

During the continuation of any such event such Lender shall have no obligation
under this Agreement to make available any Accommodation of such type, but
shall make available its pro rata share of each Borrowing by way of such other
type of Accommodation as it is then obliged to make available under this
Agreement that is requested by the applicable Borrower.

                         PAYMENTS AND INDEMNITIES


1.051   METHOD AND PLACE OF PAYMENTS

     (1) Each Lender (other than the Operating Lenders which shall make
arrangements directly with the applicable Borrowers respecting the advance of
proceeds of Accommodation under the Operating Lines) shall transfer for value
by 11:00 a.m. on each applicable Borrowing Date:

      (a)  immediately available Cdn. Dollars in an aggregate amount equal to:

           (i)  the amount of any Prime Rate Loan to be made
                by it on such Borrowing Date; and

           (ii) the amount of all BA Discount Proceeds in respect of any

                such Borrowing Date and the amount of all proceeds received
                by it as contemplated by subsection 2.05(3) in respect of
                any Bankers' Acceptance accepted by it and purchased by a
                third party on such Borrowing Date, in each case net of the
                related fee payable to such Lender pursuant to Section 3.09;

           to the Administrative Agent's Cdn. Dollar Asset Distribution
           Suspense Account in Canada, Account No. 09-21416, Transit No.
           00002, Main Branch, Commerce Court, Toronto, Canada; and

      (b)  immediately available U.S. Dollars in an aggregate amount equal to
           the amount of any U.S. Base Rate Loan and any LIBOR Loan from a Cdn.
           Cross Border Lender


   92
                                                                  SECTION 5.01

                                - 84 -


           or a Cdn. Only Lender to be made by it on such Borrowing Date to the
           Agent's U.S. Dollar Asset Distribution Suspense 
           in Canada, Account No. 02-13616, Transit No. 00002, Main 
           Commerce Court, Toronto, Canada; and

      (c)  immediately available U.S. Dollars in an aggregate amount equal to
           the amount of any U.S. Reference Rate Loan and any LIBOR Loan from a
           U.S. Cross Border Lender or a U.S. Only Lender to be made by it on
           such Borrowing Date to the Administrative Agent's account in the
           United States of America, at Morgan Guaranty Trust Company of New
           York in New York, New York, ABA 021-000-238 for further credit to
           the account of CIBC New York Agency, Account No.  630-004-80 for
           further credit to agented loans, Account No. 07-09611 - Attention
           Agency Services - Reference Philip.

Provided that no costs in excess of costs associated with a transfer to the
accounts specified in the preceding sentence would be incurred by the Borrowers
or any of the Lenders, the Administrative Agent may designate such other
accounts and offices as it may see fit for the purposes referred to in the
preceding sentence.  Subject to any direction given to the Administrative Agent
by the applicable Borrower, the Administrative Agent shall make all such
amounts received by it from the Lenders as aforesaid available to the
applicable Borrower by depositing the same for value on the applicable
Borrowing Date (a) in the case of the Cdn. Borrower to such account in Canada
in the name of such Borrower as such Borrower shall have previously designated
by timely notice in writing to the Administrative Agent, and (b) in the case of
the U.S. Borrower, to such account in the United States of America as such
Borrower shall have previously designated by timely notice in writing to the
Administrative Agent.

     (2) Notwithstanding subsection 5.01(1), the Administrative Agent shall be
entitled to assume that each Lender has made or will make available to the
Administrative Agent all funds required to be made available by such Lender as
specified in subsection 5.01(1), and the Administrative Agent may (but shall
not be obliged to), in reliance upon such assumption, make available to the
applicable Borrower a corresponding amount.  If such funds are in fact not
received by the Administrative Agent from such Lender on any Borrowing Date and
the Administrative Agent has made available the corresponding amount to the
applicable Borrower on such Borrowing Date, such corresponding amount shall not
be a Loan or the proceeds of any Bankers' Acceptances or BA Equivalent Note
made available or purchased by such Lender to or from such Borrower and the
Administrative Agent shall be entitled (in its capacity as Administrative
Agent) to recover from such Borrower, on demand, the corresponding amount made
available by the Administrative Agent to such Borrower as aforesaid together
with interest on such amount at the rate applicable under this Agreement to
Prime Rate Loans, if such amount is in Cdn. Dollars, or U.S. Base Rate Loans,
if such amount is in U.S. Dollars and was made available to the Cdn. Borrower,
or U.S. Reference Rate Loans, if such amount was made available to the U.S.
Borrower.  If, after the applicable Borrowing Date but prior to such time as


   93
                                                                  SECTION 5.01

                                - 85 -

the Administrative Agent has demanded repayment from a Borrower as permitted by
the preceding sentence, the funds required to be made available by the
applicable Lender are in fact received by the Administrative Agent, the
Administrative Agent shall be entitled to retain such funds for its own account
and the corresponding amount made available by the Administrative Agent to such
Borrower on such Borrowing Date shall, notwithstanding the preceding sentence,
be deemed to have been a Loan or the proceeds of Bankers' Acceptances or a BA
Equivalent Note, as the case may be, made available by such Lender to such
Borrower on such Borrowing Date and such Lender shall pay to the Administrative
Agent on demand, as reimbursement for expenses incurred by the Administrative
Agent, an amount equal to the product of (i) the standard interbank reference
rate then in effect in Canada (with respect to such amounts made available by
any Cdn. Only Lender or any Cdn. Cross Border Lender) or in the United States
of America (with respect to such amounts made available by any U.S. Only Lender
or any U.S. Cross Border Lender) multiplied by (ii) the corresponding amount
made available by the Administrative Agent, multiplied by (iii) a fraction, the
numerator of which is the number of days that have elapsed from and including
such Borrowing Date to the date on which such funds are received by the
Administrative Agent from such Lender and the denominator of which is the
number of days in the calendar year in which the same is to be determined.  A
certificate of the Administrative Agent with respect to any amount owing by a
Lender under this subsection shall be binding and conclusive in the absence of
manifest error.

     (3) The Cdn. Borrower undertakes at all times that any Accommodation is
outstanding to it or any other amount is owed by it under any Credit Document
to maintain at the Administrative Agent's Cdn. Payment Branch an account in
Cdn. Dollars and an account in U.S. Dollars which the Administrative Agent
shall be entitled to debit with such amounts as are from time to time required
to be paid by such Borrower under the Credit Documents, as and when such
amounts are due, and that each such account will contain sufficient funds for
such purpose.  All payments by the Cdn. Borrower under the Credit Documents
(except for payments prior to the Maturity Date to the Cdn. Operating Lender
under the Cdn. Operating Line which shall be made directly to the Cdn.
Operating Lender in accordance with arrangements entered into between the Cdn.
Borrower and the Cdn. Operating Lender from time to time), unless otherwise
expressly provided in such Credit Document, shall be made to the Administrative
Agent at the Administrative Agent's Cdn. Payment Branch for the Rateable
account of the Lenders entitled to such payment not later than 12:00 noon for
value on the date when due, and shall be made in immediately available funds
without set-off or counterclaim.  All payments by the U.S. Borrower under the
Credit Documents (except for payments prior to the Maturity Date to a U.S.
Operating Lender under a U.S. Operating Line which shall be made directly to
such U.S. Operating Lender in accordance with arrangements entered into between
the U.S. Borrower and such U.S. Operating Lender from time to time), unless
otherwise expressly provided in such Credit Document, shall be made to the
Administrative Agent at the Administrative Agent's U.S. Payment Branch for the
Rateable account of the Lenders entitled to such payment not later than 12:00
noon for value on the date when due, and shall be made in immediately available
funds without set-off or counterclaim.  Unless the Administrative Agent shall
have been notified by a


   94
                                                                  SECTION 5.01

                                - 86 -

Borrower not later than the Business Day prior to the date on which any payment
to be made by such Borrower under a Credit Document is due that such Borrower
does not intend to remit such payment, the Administrative Agent shall be
entitled to assume that such Borrower has remitted or will remit such payment
when so due and the Administrative Agent may (but shall not be obliged to), in
reliance upon such assumption, make available to each applicable Lender on such
payment date an amount equal to such Lender's Rateable share of such assumed
payment.  If such Borrower does not in fact remit such payment to the
Administrative Agent as required by the Credit Documents, each applicable
Lender shall immediately repay to the Administrative Agent on demand the amount
so made available to such Lender, together with interest on such amount at the
interbank reference rate then in effect in Canada (with respect to amounts paid
to the Cdn. Only Lenders, the Cdn. Operating Lender, the Cdn. LC Lenders or the
Cdn. Cross Border Lenders) or in the United States of America (with respect to
amounts paid to the U.S. Only Lenders, the U.S. Operating Lenders, the U.S.
Cross Border Lenders or the U.S. LC Lenders) in respect of each day from and
including the date such amount was made available by the Administrative Agent
to such Lender to the date such amount is repaid in immediately available funds
to the Administrative Agent, and such Borrower shall immediately pay to the
Administrative Agent on demand such amounts as are sufficient to compensate the
Administrative Agent and the Lenders for all costs and expenses (including,
without limitation, any interest paid to lenders of funds) which the
Administrative Agent may sustain in making any such amounts available to the
Lenders or which any Lender may sustain in receiving any such amount from and
in repaying any such amount to the Administrative Agent or in compensating the
Administrative Agent as aforesaid.  A certificate of the Administrative Agent
as to any amounts payable by a Borrower pursuant to the preceding sentence and
containing reasonable details of the calculation of such amounts shall be,
absent manifest error, prima facie evidence of the amounts so payable.  If any
amount which has been received by the Administrative Agent not later than 12:00
noon on any Business Day as provided above is not paid by the Administrative
Agent to a Lender on such Business Day as required under this Agreement, the
Administrative Agent shall immediately pay to such Lender on demand interest on
such amount at the interbank reference rate then in effect in Canada (with
respect to amounts payable to the Cdn. Only Lenders, the Cdn. Operating Lender,
the Cdn. LC Lenders or the Cdn. Cross Border Lenders) or in the United States
of America (with respect to amounts payable to the U.S. Only Lenders, the U.S.
Operating Lenders, the U.S. Cross Border Lenders or the U.S. LC Lenders) in
respect of each day from and including the day such amount was required to be
paid by the Administrative Agent to such Lender to the day such amount is so
paid.


1.052   CURRENCY OF PAYMENT

     Accommodation shall be repaid by each Borrower as required under this
Agreement in the currency in which such Accommodation was obtained by such
Borrower.  Any payment on account of an amount payable under any Credit
Document in a particular currency (the "PROPER CURRENCY") made to or for the
account of the Administrative Agent, an Other Agent or a Lender in a currency
(the "OTHER CURRENCY") other than the proper currency, whether pursuant to a


   95
                                                                  SECTION 5.02

                                - 87 -

judgement or order of any court or tribunal or otherwise and whether arising
from the conversion of any amount denominated in one currency into any other
currency for the purpose of making or filing a claim, obtaining an order or
judgement, enforcing an order or judgement or otherwise, shall constitute a
discharge of the applicable Borrower's obligation under such Credit Document
only to the extent of the amount of the proper currency which the
Administrative Agent, such Other Agent or such Lender is able, in the normal
course of its business within one Business Day after receipt by it of such
payment, to purchase with the amount of the other currency so received.  If the
amount of the proper currency which the Administrative Agent, such Other Agent
or such Lender is so able to purchase is less than the amount of the proper
currency originally due to it under such Credit Document, such Borrower shall
indemnify and save the Administrative Agent, such Other Agent or such Lender,
as the case may be, harmless from and against any loss or damage arising as a
result of such deficiency.  This indemnity shall constitute an obligation
separate and independent from any other obligation contained in any Credit
Document, shall give rise to a separate and independent cause of action, shall
apply irrespective of any indulgence granted by the Administrative Agent, any
Other Agent or any Lender from time to time, shall continue in full force and
effect notwithstanding any judgement or order for a liquidated sum in respect
of an amount due under any Credit Document or under any judgement or order and
shall not merge in any order of foreclosure made in respect of any Security or
other security given to or for the benefit of the Administrative Agent, the
Other Agents and the Lenders.


1.053   TAXES

     (1) All payments by a Borrower under the Credit Documents shall be made
free and clear of, and without reduction for or on account of, any present or
future income, capital, large corporations, stamp or other taxes, levies,
imposts, duties, charges, fees, deductions or withholdings of any kind or
nature whatsoever or any installments, interest or penalties payable with
respect thereto now or in the future imposed, levied, collected, withheld or
assessed by any country or any political subdivision of any country
(collectively "TAXES"); provided, however, that subject to subsection 5.03(2),
if any Taxes which are not Excluded Taxes are required by Applicable Law to be
withheld from any interest or other amount payable to the Administrative Agent,
any Other Agent or any Lender under any Credit Document, the amount so payable
to the Administrative Agent, such Other Agent or such Lender shall be increased
to the extent necessary to yield to the Administrative Agent, such Other Agent
or such Lender, on a net basis after payment of all Taxes other than Excluded
Taxes (including all Taxes other than Excluded Taxes imposed on any additional
amounts payable under this subsection) and after payment of all Excluded Taxes
imposed by any relevant jurisdiction on any additional amounts payable under
this subsection, interest or any such other amount payable under such Credit
Document at the rate or in the amount specified in such Credit Document.  Each
Borrower shall be fully liable and responsible for and shall, promptly
following receipt of a request from the Administrative Agent, pay to the
Administrative Agent any and all sales, goods and services and harmonized sales
and goods and services taxes payable under the laws of Canada, any Province of
Canada, the United


   96
                                                                  SECTION 5.03

                                - 88 -

States of America, any State of the United States of America or any other
country or jurisdiction with respect to any and all goods and services made
available under the Credit Documents to such Borrower by the Administrative
Agent, the Other Agents and the Lenders, and such taxes shall be included in
the definition of "Taxes" for all purposes of this Agreement.  Whenever any
Taxes are payable by a Borrower, as promptly as possible thereafter it shall
send to the Administrative Agent, for the account of the Administrative Agent
and each affected Other Agent and Lender, a certified copy of an original
official receipt showing payment of such Taxes.  If a Borrower fails to pay any
Taxes when due or if a Borrower fails to remit to the Administrative Agent the
required documentary evidence of such payment, such Borrower shall indemnify
and save harmless the Administrative Agent, the Other Agents and the Lenders
from any incremental taxes, interest, penalties or other liabilities that may
become payable by the Administrative Agent, by any Other Agent or by any Lender
or to which the Administrative Agent, any Other Agent or any Lender may be
subjected as a result of any such failure.  A certificate of the Administrative
Agent, any Other Agent or any Lender as to the amount of any such taxes,
interest or penalties and containing reasonable details of the calculation of
such taxes, interest or penalties shall be, absent manifest error, prima facie
evidence of the amount of such taxes, interest or penalties, as the case may
be.

     (2) If a Borrower makes any payment to any Lender pursuant to subsection
5.03(1) and such Lender shall receive any tax benefit which it would not have
received if there had been no such payment, such Lender agrees to pay to such
Borrower the amount of such tax benefit (to a maximum of the payment made by
such Borrower) after the same has been obtained; provided, however, that (i)
this subsection shall place such Lender in no worse position than it would have
been if such Borrower had not been required to make such payment; (ii) no Event
of Default shall have occurred and be continuing; and (iii) any subsequent
disallowance, elimination, reduction, deferral, disqualification or recapture
of all or any part of a tax benefit of a Lender for which a payment by such
Lender to a Borrower has been made (or is due) pursuant to this subsection
shall be treated as a Tax subject to indemnification hereunder.  Each Lender
shall have sole discretion as to whether or not it will seek any tax benefit
and as to the allocation of its income, and no Lender shall be obliged to
disclose any information to any Borrower regarding its income or taxes.

     (3) Each U.S. Only Lender, U.S. Cross Border Lender, U.S. Operating Lender
and U.S. LC Lender (collectively the "U.S. LENDERS") that is not a United
States person (as such term is defined in Section 7701(a)(30) of the Code) for
U.S. Federal income tax purposes agrees to deliver to the U.S. Borrower and the
Administrative Agent on or prior to the Closing Date, or in the case of a
Lender that is an assignee or transferee of an interest of a U.S. Lender under
this Agreement pursuant to Section 12.01 (unless the respective Lender was
already a U.S. Lender immediately prior to such assignment or transfer) or
otherwise becomes a U.S. Lender after the Closing Date, on the date of such
assignment or transfer to such Lender or the date on which such Lender becomes
a U.S. Lender, as the case may be:


   97
                                                                  SECTION 5.03

                                - 89 -


      (a)  two accurate and complete original signed copies of Internal Revenue
           Service Form 4224 or 1001 (or successor forms) certifying to such
           Lender's entitlement to a complete exemption from United States
           withholding tax with respect to payments to be made under this
           Agreement; or

      (b)  if the Lender is not a "bank" within the meaning of Section
           881(c)(3)(A) of the Code and cannot deliver either Internal Revenue
           Service Form 4224 or 1001 pursuant to paragraph (a) above:

             (i)  a certificate substantially in the form of Schedule 15 (any
                  such certificate being a "NON-BANK CERTIFICATE"); and

             (ii) two accurate and complete original signed copies of Internal
                  Revenue service Form W-8 (or successor form) certifying to
                  such Lender's entitlement to a complete exemption from United
                  States withholding tax with respect to payments of interest
                  to be made under this Agreement.

In addition, each U.S. Lender agrees that from time to time after the Closing
Date or after such Lender becomes a U.S. Lender (whether because of an
assignment or transfer or otherwise), when a lapse in time or change in
circumstances renders the previous certification obsolete or inaccurate in any
material respect, it will deliver to the U.S. Borrower and the Administrative
Agent two new accurate and complete original signed copies of Internal Revenue
Service Form 4224 or 1001, or Form W-8 and a Non-Bank Certificate, as the case
may be, and such other forms as may be required in order to confirm or
establish the entitlement of such Lender to a continued exemption from or
reduction in United States withholding tax with respect to payments under this
Agreement, or it shall immediately notify the U.S. Borrower and the
Administrative Agent of its inability to deliver any such Form or Certificate,
in which case such U.S. Lender shall not be required to deliver any such Form
or Certificate pursuant to this subsection.  Notwithstanding anything to the
contrary contained in subsection 5.03(1), but subject to the last sentence of
this subsection:

      (c)  the U.S. Borrower shall be entitled, to the extent it is required to
           do so by Applicable Law, to deduct or withhold income or similar
           Taxes imposed by the United States (or any political subdivision or
           taxing authority thereof or therein) from interest, fees or other
           amounts payable under this Agreement for the account of any U.S.
           Lender which is not a United States person (as such term is defined
           in Section 7701(a)(30) of the Code) for U.S. Federal income tax
           purposes to the extent that such Lender has not provided to the U.S
           Borrower U.S. Internal Revenue Service Forms that establish a
           complete exemption from such deduction or withholding; and


   98
                                                                  SECTION 5.03

                                - 90 -


      (d)  the U.S. Borrower shall not be obligated pursuant to subsection
           5.03(1) to gross-up payments to be made to a U.S. Lender in respect
           of income or similar Taxes imposed by the United States if (i) such
           Lender has not provided to the U.S. Borrower the Internal Revenue
           Service Forms required to be provided to the U.S.  Borrower pursuant
           to this subsection or (ii) in the case of a payment, other than
           interest, to a U.S. Lender described in paragraph (b) above, to the
           extent that such Forms do not establish a complete exemption from
           withholding of such Taxes.

Notwithstanding anything to the contrary contained in the preceding sentence or
elsewhere in this Section, the U.S. Borrower agrees to pay any additional
amounts and to indemnity each U.S. Lender in the manner set forth in subsection
5.03(1) (without regard to the identity of the jurisdiction requiring the
deduction or withholding) in respect of any Taxes deducted or withheld by it as
described in the immediately preceding sentence as a result of any changes
after the Closing Date in any Applicable Law, or in the interpretation thereof,
relating to the deducting or withholding of such Taxes.


1.054   INCREASED COSTS

     If subsequent to the date of this Agreement any change in or introduction
of any Applicable Law or of any administrative policy or practice of any
Governmental Authority, or compliance by any Lender with any request or
directive (whether or not having the force of law) by any Governmental
Authority (including any central bank, Superintendent of Financial Institutions
or other comparable authority or agency) having jurisdiction shall:

      (a)  subject the Administrative Agent, such Other Agent or such Lender to
           any Tax of any kind whatsoever including Excluded Taxes with respect
           to this Agreement or any other Credit Document, any Commitment or
           any Accommodation made by such Lender, or change the basis of
           taxation of payments to the Administrative Agent, such Other Agent
           or such Lender of principal, interest, fees or any other amount
           payable under any Credit Document (except for changes in the rate of
           Tax on the overall net income of the Administrative Agent, such
           Other Agent or such Lender imposed by its jurisdiction of
           incorporation, the jurisdiction of its principal office or
           applicable lending office, or any political subdivision of any such
           jurisdiction);

      (b)  impose, modify or make applicable any capital maintenance or capital
           adequacy requirement, reserve requirement, special deposit
           requirement or other similar requirement against assets held by, or
           deposits or other liabilities in or for the account of, or any
           Accommodation or Commitment made available or established by, or any
           other acquisition of funds by, such Lender; or


   99
                                                                  SECTION 5.04

                                - 91 -


      (c)  impose on the Administrative Agent, such Other Agent or such Lender
           or the London interbank market any other condition, restriction or
           limitation;

and the result of any of the foregoing is to increase the cost to the
Administrative Agent, such Other Agent or such Lender of making or maintaining
any Accommodation or Commitment or to reduce any amount otherwise receivable by
it under this Agreement or any other Credit Document with respect to any
Accommodation or Commitment or otherwise, then provided that such additional
cost or reduced amount receivable is not fully offset at all relevant times by
an increase in the applicable interest rate or rates or fees under this
Agreement or other applicable Credit Document, the Borrowers (or each
applicable Borrower in the case of any Commitment to, or any Accommodation
outstanding to, such Borrower) shall promptly pay to the Administrative Agent,
such Other Agent or such Lender, upon demand, such additional amounts necessary
to compensate the Administrative Agent, such Other Agent or such Lender, after
taking into account all applicable Taxes and Excluded Taxes, for such
additional cost or reduced amount receivable which the Administrative Agent,
such Other Agent or such Lender deems to be material as are determined in good
faith by the Administrative Agent, such Other Agent or such Lender.  If the
Administrative Agent, an Other Agent or a Lender becomes entitled to claim any
additional amount pursuant to this Section, it shall notify the Borrowers,
through the Administrative Agent, of the event by reason of which it has become
so entitled promptly upon the Administrative Agent, such Other Agent or such
Lender becoming aware of such event.  A certificate of the Administrative
Agent, an Other Agent or a Lender as to any such additional amount payable to
it and containing reasonable details of the calculation of such amount shall
be, absent manifest error, prima facie evidence of such amount.


1.055   INDEMNITIES

     (1) Each Borrower shall indemnify and save harmless the Administrative
Agent, each Other Agent and each Lender from all claims, demands, liabilities,
damages, losses, costs, charges and expenses (including the reasonable fees and
expenses of counsel for the Administrative Agent, the Other Agents and the
Lenders), including any loss or expense arising from interest or fees payable
by the Administrative Agent, such Other Agent or such Lender to lenders of
funds obtained by it in order to make or maintain any Accommodation and any
loss or expense incurred in liquidating or re-employing deposits from which
such funds were obtained, which may be incurred by the Administrative Agent,
such Other Agent or such Lender as a consequence of (i) default by such
Borrower in the payment when due of any amount payable under any Credit
Document, (ii) default by such Borrower in obtaining a Borrowing on the date
specified in any applicable notice relative to such Borrowing after such
Borrower has given such notice under this Agreement that it desires to obtain
such Borrowing, (iii) default by such Borrower in making any optional repayment
of outstanding Accommodation after such Borrower has given notice under this
Agreement that it desires to make such repayment, (iv) the repayment by such
Borrower of any LIBOR Loan otherwise than on the expiration of any applicable
LIBOR Period or the repayment of any other Accommodation otherwise than on the
maturity date of


   100
                                                                  SECTION 5.05

                                - 92 -


such Accommodation (including without limitation any such payment pursuant to
any of the provisions of Article Four or upon acceleration pursuant to Section
9.02), (v) the entering into by the Administrative Agent, such Other Agent or
such Lender of this Agreement and the other Credit Documents to which the
Administrative Agent, such Other Agent or such Lender is a party and any
amendment, waiver or consent relating hereto or thereto, and, otherwise than
are determined by a court of competent jurisdiction to be attributable
primarily to the gross negligence or wilful misconduct of the Administrative
Agent, such Other Agent or such Lender, the performance by the Administrative
Agent, such Other Agent or such Lender of its obligations under this Agreement
and the other Credit Documents, and (vi) the application by any Borrower of any
Accommodation or any proceeds of any Accommodation.  A certificate of the
Administrative Agent, an Other Agent or any Lender as to any such loss or
expense and containing reasonable details of the calculation of such loss or
expense shall be, absent manifest error, prima facie evidence of the amount of
such loss or expense, as the case may be.

     (2) The Borrowers shall indemnify and save harmless each LC Lender from
all claims, demands, liabilities, damages, losses, costs, charges and expenses
which may be asserted against or incurred by such LC Lender, otherwise than as
are determined by a court of competent jurisdiction to be attributable
primarily to the gross negligence or wilful misconduct of such LC Lender, as a
direct or indirect consequence of the issuance or renewal of any Letter of
Credit at the request of such Borrower or of any failure by any LC Issuer to
make any payment under any Letter of Credit issued at the request of such
Borrower as a result of any law, control or restriction rightfully or
wrongfully exercised or imposed by any Governmental Authority.

     (3) Each Borrower shall indemnify and save harmless the Administrative
Agent, each Other Agent and each Lender and their respective Affiliates,
agents, officers, directors and employees (each an "INDEMNIFIED PARTY") from
all claims, demands, liabilities, damages, losses, costs, charges and expenses
(including without limitation any investigatory, remedial, clean-up, compliance
or preventative costs, charges and expenses) which may be asserted against or
incurred by such Indemnified Party, otherwise than as are determined by a court
of competent jurisdiction to be attributable primarily to the gross negligence
or wilful misconduct of such Indemnified Party, whether upon realization of the
Security, or as a lender to the Cdn. Borrower or the U.S. Borrower, or as
successor to or assignee of any right or interest of the applicable Borrower,
or any of the Cdn. Borrower's Subsidiaries or as a result of any order,
investigation or action by any Governmental Authority relating to any one of
its or their business or property, or as mortgagee in possession or successor
or successor-in-interest to any one of the Borrowers, their respective
Subsidiaries, or as a result of any taking of possession of all or any real
property by foreclosure, deed or deed in lieu of foreclosure or by any other
means relating to the Borrowers, or any of their Subsidiaries under or on
account of any applicable Environmental Law, (including the assertion of any
Lien thereunder) with respect to:

      (a)  the Release of a Contaminant, the threat of the Release of any
           Contaminant, or the presence of any Contaminant affecting the real
           or personal property of a Borrower


   101
                                                                  SECTION 5.05

                                - 93 -


           or any of its Subsidiaries, whether or not the Contaminant 
           or emanates from a Borrower's property or any other 
           property or personal property located thereon (unless such 
           property or property is under the control of a Lender due to 
           relationship with a third party), including any loss of value 
           the property of a Borrower or any of its Subsidiaries as a 
           result of any of the foregoing;

      (b)  the Release of a Contaminant owned by, or under the charge,
           management or control of, a Borrower or any of its Subsidiaries or
           any predecessors or assignors thereof;

      (c)  any costs of removal or remedial action incurred by any Governmental
           Authority or any costs incurred by any other Person or damages from
           injury to, destruction of, or loss of natural resources in relation
           to, the real property or personal property of a Borrower or any of
           its Subsidiaries or any contiguous real property or elsewhere or
           personal property located thereon, including reasonable costs of
           assessing such injury, destruction or loss incurred pursuant to
           Environmental Law;

      (d)  liability for personal injury or property damage arising by reason
           of any civil law offenses or quasi-criminal offenses or under any
           statutory or common tort law theory and any and all other third
           party claims of any and every nature whatsoever, including, without
           limitation, damages assessed for the maintenance of a public or
           private nuisance or for the carrying on of a dangerous activity at,
           near, or with respect to the real or personal property of a
           Borrower, or any of its Subsidiaries or elsewhere; and/or

      (e)  any other matter relating to the Natural Environment and
           Environmental Law affecting the property or the operations and
           activities of a Borrower or any of its Subsidiaries within the
           jurisdiction of any Governmental Authority.

      The Borrowers' obligations shall arise both on the discovery of the
      presence of any Contaminant that has not been dealt with in accordance
      with Environmental Law and shall also arise where any Governmental
      Authority has taken or threatened any action in connection with the
      presence of, or any Environmental Activity respecting, any Contaminant.
      Each Borrower acknowledges that the Lenders have agreed to make the
      Credit available in reliance on the Borrowers' representations,
      warranties and covenants, including the delivery of this indemnity.  This
      indemnity supersedes any other provisions of this Agreement or any other
      Credit Document which in any way limits the liability of a Borrower.  The
      obligations of the Borrowers arising under this indemnity will be
      absolute and unconditional and shall not be affected by any act,
      omission, or circumstances whatsoever, whether or not occasioned by the
      fault of the Administrative Agent, the Other Agents or the Lenders except
      as determined by a court of competent jurisdiction to



   102
                                                                  SECTION 5.05

                                - 94 -
      

      be primarily due to gross negligence or wilful misconduct of the
      Administrative Agent, the Other Agents or the Lenders.  The foregoing
      indemnities will survive the Disposition of any or all right, title and
      interest in and to the real property and personal property of the
      Restricted Parties and their Subsidiaries to any Person, including,
      without limitation, whether or not affiliated with the Restricted Parties
      and their Subsidiaries.

1.064   REGISTRATION

     The Administrative Agent may, at the reasonable expense of the Borrowers,
register, file or record the Security or notices in respect of the Security in
all offices where such registration, filing or recording is, in the opinion of
the Administrative Agent or its counsel, necessary or of advantage to the
creation, perfection and preservation of the Liens arising pursuant to the
Security.  The Administrative Agent may, at the Borrowers' reasonable expense,
renew such registrations, filings and recordings from time to time as and when
required to keep them in full force and effect.  The Borrowers acknowledge that
the forms of Security have been prepared based upon Applicable Law in effect at
the date of execution of the Security and that such laws may change, and that
the laws of other jurisdictions may require the execution and delivery of
different forms of security instruments in order to grant to the Administrative
Agent, the Other Agents, the Lenders and their respective Eligible Affiliates
the rights intended to be granted by the Security.  The Borrowers will, and
will cause the other Restricted Parties to, on request from the Administrative
Agent from time to time, execute and deliver to the Administrative Agent such
additional security instruments and will amend or supplement, and will cause
the other Restricted Parties to amend or supplement, any Security theretofore
provided to the Administrative Agent:

      (a)  to reflect any changes in such laws, whether arising as a result of
           statutory amendments, court decisions or otherwise;

           Security in all appropriate jurisdictions; or

      (c)  if any Person having delivered Security amalgamates or merges with

in each case in order to confer upon the Administrative Agent, the Other
Agents, the Lenders and their respective Eligible Affiliates such Liens with
such priority as are intended to be created by the Security.  The Borrowers
will pay or indemnify the Administrative Agent, the Other Agents, the Lenders
and their respective Eligible Affiliates against any and all stamp duties,
registration fees and similar taxes or charges which may be payable or
determined to be payable in connection with the execution, delivery,

         either Borrower be paid out of any grant of Accommodation under the
         Credit.  Failure to deduct actual or estimated fees and disbursements

         required by the Administrative Agent.

         would be created thereby, any Wholly-Owned Restricted Party may be
         amalgamated or consolidated or merged or liquidated, wound-up or
         dissolved with or into a Borrower, provided that such Borrower shall be
         the continuing corporation, or with or into any one or more other
         Wholly-Owned Restricted Parties provided that if any such Restricted
         Party is a Material Restricted Party, a Material Restricted Party shall

            (i)    each of the Restricted Parties may Dispose of, in the normal
                   course of its business for the purpose of carrying on the
                   same, for fair market value, in accordance with customary
                   trade terms, any tangible property that would reasonably be
                   considered to be the subject matter of sales by it in the
                   normal course of its business for the purpose of carrying on
                   the same, or

                   provided all Security required to be provided under this
                   Agreement;

          (iii)    the Restricted Parties may, so long as no Default or Event of
                   Default is continuing or would be created thereby, provided
                   that such Disposition would not have, or have any reasonable
                   likelihood of having, a Material Adverse Effect, in addition
                   to the other transactions permitted by this subsection (d),
                   Dispose of property in any Financial Year (the "REFERENCE
                   FINANCIAL YEAR") provided however that:

                   (x)  on the Business Day following the date of the closing of
                        any such Disposition an amount equal to that portion, if
                        any, of the purchase price payable to the Restricted

                        the Borrowers to the Administrative Agent to repay
                        Accommodation under the Credit as provided for in
                        subsection 4.04(1); and

                   (y)  on that date which is one year from and including the
                        date of the closing of any such Disposition (the
                        "ANNIVERSARY" of such Disposition) in respect of which
                        the fair market value at the time of such Disposition of
                        the property so Disposed of exceeds (the amount of such
                        excess being the "DEEMED EXCESS PROCEEDS OF DISPOSITION
                        AMOUNT" relative to such Disposition) the greater of (1)
                        $0, and (2) U.S. $50,000,000 (or the Equivalent Amount
                        in any other currency or currencies) less the fair
                        market value of all other property of the Restricted
                        Parties Disposed of prior to such time under this
                        paragraph of this subsection during the Reference
                        Financial Year:

                        (A)  the limit of the Credit will be permanently reduced
                             by an amount (the "PERMANENT DISPOSITION REDUCTION
                             AMOUNT" relative to such Disposition) equal to the
                             amount, if any, by which (X) the Deemed Excess
                             Proceeds of Disposition Amount relative to such
                             Disposition exceeds (Y) the amount, if any, which
                             has been Reinvested in the

                             such Disposition to the Anniversary of such
                             Disposition and which has not previously been used
                             in the calculation of the Permanent Disposition
                             Reduction Amount relative to any other Disposition;
                             and

                        (B)  the Borrowers shall make such permanent repayments
                             of Accommodation, if any, required under the
                             provisions of subsection 4.04(2); and

           (iv)    a Restricted Party may enter into an arrangement to factor or
                   securitize accounts receivable or monetize inventory of such
                   Restricted Party provided however that no Default or Event of
                   Default has occurred and is continuing at the time of giving
                   effect to, or would result from or be created by giving
                   effect to, such arrangement and provided further that in
                   connection with any such arrangement other than such an
                   arrangement involving only Guarantor Subsidiaries:

                   (w)  such arrangement is entered into with third parties on
                        an arm's length basis on reasonable commercial terms
                        consistent with those entered into by other Persons in
                        similar transactions in the market place;

                   (x)  the proceeds from such arrangement are used solely for
                        the working capital purposes of the Restricted Parties;

                   (y)  such arrangement is without any Recourse Against any
                        Restricted Party; and

                        receivable generated by the Restricted Parties and owned

                        all such factoring or securitization arrangements, and
                        (B) the value (determined in accordance with GAAP in the
                        same manner as used by the Restricted Parties to value
                        their other inventory) of all inventory created or
                        acquired by the Restricted Parties and owned or held at
                        such time by another Person or by other Persons under

                        currency or currencies).  For greater certainty there
                        will not be included in calculating the amounts referred
                        to in clauses (A) and (B) of this paragraph the face

                        Subsidiaries prior to the date of the Acquisition of
                        such Target by a Restricted Party and sold to another
                        Person or Persons by such Target or its Subsidiaries
                        prior to the date of such Acquisition under monetization
                        arrangements entered into by such Target or its
                        Subsidiaries prior to such date, in each case provided
                        that neither such arrangement nor such sale was entered
                        into or effected in connection with, or in anticipation

         currencies).

    (f)  Restricted Payments.  Make any Restricted Payment, except that, so long
         as no Default or Event of Default is continuing (other than with
         respect to Restricted Payments which are in the form of management or
         consulting fees or bonuses payable to officers or directors of a
         Restricted Party in accordance with bona fide arrangements entered into
         in good faith in the ordinary course of business consistent with past
         practices, which may be paid in the circumstances provided for in
         paragraphs (i) and (ii) of this subsection although a Default or Event
         of Default may be continuing provided that amounts owing under this
         Agreement have not been accelerated at or prior to such time pursuant
         to Section 9.02) or would be created thereby:

                   to a Borrower or to any other Wholly-Owned Restricted Party;

           (ii)    the Cdn. Borrower may make Restricted Payments at any time

         agreement to Dispose of, or grant any option respecting, any shares or
         other equity interest in any Restricted Party now or hereafter directly
         or indirectly held by any Restricted Party or in any other way permit
         any reduction in the direct or indirect voting interest, or the direct
         or indirect equity interest, of any Restricted Party in any other
         Restricted Party.  For greater certainty, nothing in this subsection
         prohibits shareholders of the Cdn. Borrower from Disposing of any
         shares in the Cdn. Borrower held by them.

    (h)  No Share Issuance.  Except for the issue of common shares by the Cdn.
         Borrower, issue any securities unless the Person to whom such
         securities are issued is a Restricted Party and then only if (i) the
         issue of such securities would not result in any reduction in the
         direct or indirect voting interest, or the direct or indirect equity
         interest, of any Restricted Party in the Restricted Party issuing such
         securities, and (ii) if any of the securities of the issuing Restricted
         Party are pledged to the Administrative Agent under the Security, the
         additional securities so issued are validly pledged for the benefit of
         the Administrative Agent and the Lenders under the Security.

         this Agreement, enter into any transaction, including the purchase,
         Disposition of any property or the rendering of any services, with any
         Affiliate that is not a Wholly-Owned Restricted Party, or with any of

         exist any employment, consulting or analogous agreement or arrangement
         with any such Affiliate or with any of its or their directors or
         officers, except a transaction or agreement or arrangement (i) which is
         in the ordinary course of business of such Restricted Party and which
         is upon fair and reasonable terms not less favorable to such Restricted
         Party than it would obtain in a comparable arm's-length transaction,
         and (ii) if the aggregate value of such transaction or agreement, or
         the property or services covered by such transaction or agreement,
         could reasonably be expected to exceed U.S. $50,000,000 (or the
         Equivalent Amount in any other currency or currencies), in respect of
         which such Restricted Party has first delivered a letter from an

         requirements of this subsection.

    (j)  Sale and Leaseback.  Enter into any arrangement with any Person
         providing for the leasing by any of the Restricted Parties, as lessee,
         of property which has been or is to be Disposed of by any Restricted
         Party to such Person or to any other Person to whom funds have been or
         are to be advanced by such Person on the security of such property or
         the lease obligation of any of the Restricted Parties provided that the
         Restricted Parties may enter into such a sale and lease back
         transaction provided that

            (i)    no Default or Event of Default has occurred and is continuing
                   at the time of, or would result from or be created by giving

                   Agreement; and

          (iii)    in connection with any such transaction other than a sale and
                   lease back of property consisting only of Rolling Stock and

                   (x)  the Disposition of the property subject to such
                        transaction shall constitute a Disposition of property
                        under paragraph 8.02(d)(iii) and the proceeds from such
                        Disposition shall be applied as provided for in such
                        paragraph and elsewhere in this Agreement; and

                   to such Acquisition with the provisions of the Credit

         For greater certainty, the provisions of this subsection will not
         prohibit an Acquisition (including an Acquisition by an Independent

         given after the date of this Agreement as permitted under subsection
         8.02(e) by all Restricted Parties, U.S. $50,000,000 (or the Equivalent
         Amount in any other currency or currencies); provided, however, that
         this limitation shall not apply to assurances or obligations of
         Restricted Parties which are excluded from the definition of Contingent
         Obligation pursuant to paragraph (c) of such definition.

    (m)  No Change of Fiscal Year.  Change its financial year end of December

    (q)  Arrangements with Independent Subsidiaries.  Except to the extent that
         the same constitutes an Investment permitted under subsection 8.02(e)
         or Financial Assistance permitted under subsection 8.02(l), provide any
         Financial Assistance to any Independent Subsidiary or take or fail to
         take any other action, or permit any Independent Subsidiary to take or
         fail to take any action, which could result in any creditor of an
         Independent Subsidiary having any Recourse Against any Restricted
         Party.

    (r)  Hedging Arrangements.  Enter into any Hedging Arrangement unless such
         Hedging Arrangement:

1.084 INTERPRETATION OF CERTAIN COVENANTS
      -----------------------------------

     The specification in Article Three of interest rates and fees for a range
which is different than the covenants set forth in Section 8.03, does not limit
the extent of, or relieve the Borrowers from complying with, the covenants in
this Agreement.


                                  ARTICLE NINE
                                  ------------

    (b)  Default in Interest, etc. If a Borrower fails to pay any interest, fees

         (b) and (c), if a Restricted Party or any Independent Subsidiary
         defaults in the performance or observance of any term, condition or
         covenant contained in any Credit Document and, with respect to any
         covenant which is capable of being cured, such default continues for a
         period of 15 days or more after written notice of such default has been
         delivered by the Administrative Agent or the Required Lenders to the
         applicable Person (provided that the grace period can be abridged by
         the Administrative Agent or the Required Lenders with respect to any
         covenant

   138
                                                                    SECTION 9.01

         Administrative Agent or the Required Lenders consider that the delay
         would impair the Security or if the nature or rank of the Security is
         being challenged).

    (e)  Representations and Warranties.  If any representation, warranty or
         statement made in any Credit Document or any certificate or other
         document delivered to the Administrative Agent, any Other Agent or any

         material respect when made or when deemed to have been made.

    (f)  Default under Other Agreements with Lenders.  If a Restricted Party
         defaults in the performance or observance of any term, condition,

         Arrangement or in any other agreement between such Restricted Party and
         the Administrative Agent, any of the Other Agents or any of the Lenders

         amount or amounts exceeding an aggregate of U.S. $10,000,000 (or the

         which any one or more of the Restricted Parties shall have failed to
         make a payment when due and payable, or if any amount or amounts
         exceeding an aggregate of U.S. $10,000,000 (or the Equivalent Amount in
         any other currency or currencies) shall have become due and payable by,
         or could then be declared by the Person to whom such amount is to be
         paid to be due and payable by, any one or more of the Restricted
         Parties prior to the stated maturity date thereof or prior to the
         regularly scheduled date for payment thereof as a result of any default
         or event of default (however described) or other failure by any one or
         more of the Restricted Parties to perform or observe any obligation or
         covenant.

    (h)  Credit Documents.  If any Credit Document or any part thereof shall, at
         any time after its respective execution and delivery and for any
         reason, cease in any way to be in full force and effect or if the
         Security or any part thereof shall, at any time after its execution and
         delivery and for any reason, cease to constitute a Lien of the nature
         and priority specified in or contemplated by this Agreement, and in
         either such case such event continues for a period of 15 days after
         notice thereof from the Administrative Agent or the Required Lenders to
         the Cdn. Borrower, or if the validity or enforceability of any Credit
         Document is disputed in any manner by any of the parties thereto other

Hedging Arrangements (collectively the "SECURED PARTY DOCUMENTS"), if there
shall exist at any time any amount payable by any Secured Party to any other
Secured Party pursuant to any provision of any Secured Party Document, then
such amount shall be taken into account when calculating, and an appropriate
portion of such amount shall be paid from, any proceeds of Security otherwise
payable to such first Secured Party.

     (2) Each Borrower agrees that, upon the occurrence of an Event of Default,
in addition to (and without limitation of) any right of set-off, bankers' lien,
counterclaim or other right or remedy that any Secured Party may otherwise
have, each Secured Party shall be entitled, at its option, but subject to
subsection 9.03(3), to offset any and all balances held by it for the account
of such Borrower at any of its offices or branches, in any currency, against
any and all amounts owed by such Borrower to such Secured Party under any
Secured Party Document (regardless of whether any such balances are then due or
payable to such Borrower), in which case such Secured Party shall promptly
notify such Borrower and the Administrative Agent thereof; provided that such
Secured Party's failure to give any such notice shall not affect the validity
thereof.  Any Person purchasing an interest in the obligations of any Borrower
as contemplated by subsection 9.03(3) may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such interest as
fully as if such obligations had been originally incurred to such Person and
such Person were the holder thereof.

     (3) Each Secured Party (a "SURPLUS SECURED PARTY") that receives any
payment or recovery (except (i) interest and fees paid as required pursuant to
the Credit Documents prior to the acceleration of any payment or the
termination of the Credit and the Commitments pursuant to Section 9.02, (ii)
payments made in accordance with subsections 8.01(s) or 9.02(2) or Articles
Four or Five prior to the acceleration of any payment or the termination of the
Credit and the Commitments pursuant to Section 9.02 (including any prepayment
of any or all amounts owing under the Credit Documents prior to the Maturity
Date), (iii) payments made by a Borrower to a Secured Party under a
Lender/Borrower Hedging Arrangement between such Borrower and such Secured
Party, in accordance with the provisions of such Hedging Arrangement, prior to
the acceleration of any payment or the termination of the Credit and the
Commitments pursuant to Section 9.02, and (iv) any payment pursuant to this
subsection 9.03(3)) from, or from the property of, any Restricted Party in
respect of any obligation of a Restricted Party to such Secured Party under any
Secured Party Document (whether by voluntary payment, by realization of any
security held by such Secured Party, by exercise of a right of set-off or
banker's lien, by counterclaim or cross action, by the enforcement of any of
the Secured Party Documents, by reason of any priority afforded in any
insolvency proceeding, or otherwise) in an amount which, relative to the
corresponding amounts received by the other Secured Parties (the "DEFICIENT
SECURED PARTIES"), is a greater proportion than the proportion which the
obligations of such Borrower to the Surplus Secured Party under the Secured
Party Documents bears to the obligations of such Borrower to the Deficient
Secured Parties under the Secured Party Documents immediately prior to such
receipt (in each case without regard to any Excess Amounts as defined in
subsection 9.03(5)), the Surplus Secured Party shall purchase for cash

   144
                                                                    SECTION 9.03

                                    - 136 -




from the Deficient Secured Parties, without recourse, an interest in the
obligations of the Restricted Parties to the Deficient Secured Parties under
the Secured Party Documents in such amount as shall result in a Rateable
participation (subject to subsection 9.03(5)) by all of the Secured Parties in
the obligations of the Restricted Parties to all of the Secured Parties under
the Secured Party Documents (provided that, to the extent that the Secured
Parties determine that the same is practicable, any such purchase will be
structured to minimize any increase of the amount for which any Borrower is
liable in respect of Taxes pursuant to Section 5.03 and, if requested by the
Administrative Agent, any such purchase shall be accompanied by an indemnity in
favour of the Administrative Agent for any liability which the Administrative
Agent may incur to any Governmental Authority in connection with any such
increased Taxes for which any Restricted Party becomes liable pursuant to
Section 5.03); provided, however, that if the Surplus Secured Party is
thereafter required to relinquish all or any portion of such excess payment or
recovery to any Person (other than to the Deficient Secured Parties as provided
herein), such purchase shall be rescinded and the purchase price restored to
the extent of such recovery, but without interest.  The Administrative Agent,
upon consultation with the applicable Secured Parties, shall have the power to
settle any documentation required to evidence any such purchase or restoration
and, if deemed advisable by the Administrative Agent, to execute any document
as attorney for any Secured Party in order to complete any such purchase or
restoration.  The Borrowers acknowledge that the foregoing arrangements are to
be settled by the Secured Parties among themselves, and the Borrowers expressly
consent to the foregoing arrangements among the Secured Parties.

     (4) Nothing contained in the Secured Party Documents shall require any
Secured Party to exercise any right, or shall affect the right of any Secured
Party to exercise and retain the benefits of exercising any right, with respect
to any indebtedness or obligation of any of the Borrowers existing otherwise
than pursuant to the Secured Party Documents.

     (5) Notwithstanding any other provisions of any of the Secured Party
Documents, the aggregate amount (the "EXCESS AMOUNT") of any obligations owing
by the Borrowers to a Secured Party under a Tranche on the date of any
acceleration under Section 9.02 which are in excess of such Secured Party's
Commitment under such Tranche at such time shall not, as among the Secured
Parties, be treated as outstanding Accommodation from such Secured Party for
the purpose of determining the Secured Party's Rateable entitlement to proceeds
from the Security or other enforcement proceedings, with the intent that
proceeds from Security and from any other enforcement proceedings shall be
distributed first to the Secured Parties Rateably only on the basis of
outstanding Accommodation and other amounts ("PRIOR AMOUNTS") owing under the
Secured Party Documents which are not Excess Amounts and second, only after
payment of all such Prior Amounts (and all interest, fees and other amounts
payable relative to such Prior Amounts), Rateably to the Secured Parties on the
basis of all Excess Amounts.

1.094 REMEDIES CUMULATIVE
      -------------------

     The rights and remedies of the Administrative Agent, the Other Agents and
the Lenders under the Credit Documents are cumulative and in addition to and
not in substitution for any rights or remedies provided by any other agreement,
at law, in equity, under statute or otherwise.

1.095 APPROPRIATION OF MONEYS RECEIVED
      --------------------------------

     Each of the Administrative Agent, the Other Agents and the Lenders may
from time to time when an Event of Default has occurred and is continuing, but
subject to subsection 9.03(3), appropriate any moneys received by it from the
Restricted Parties or from any security held by such Person in or toward
payment of such of the obligations of the Borrowers or any other Restricted
Party under the Credit Documents as such Person in its sole discretion may see
fit.

1.096 NON-MERGER
      ----------

     The taking of a judgment or judgments or any other action or dealing
whatsoever by the Administrative Agent, any Other Agent or any Lender in
respect of the Security will not operate as a merger of any indebtedness or
liability of either of the Borrowers to the Administrative Agent, any Other
Agent or any of the Lenders or in any way suspend payment or affect or
prejudice the rights, remedies and powers, legal or equitable, which the
Administrative Agent, any Other Agent or any Lender may have in connection with
such liabilities and the surrender, cancellation or any other dealings with any
security for such liabilities will not release or affect the liability of
either of the Borrowers or any other Restricted Party under any of the Credit
Documents or any security held by or on behalf of the Administrative Agent, the
Other Agents and the Lenders.

whether the powers which the Administrative Agent is purporting to exercise have
become exercisable or otherwise as to the propriety or regularity of any other
action on the part of the Administrative Agent, and accordingly insofar as the
Restricted Parties are concerned the Administrative Agent shall for all purposes
hereof be deemed to have authority from the Lenders to exercise the powers and
take the actions which are in fact exercised and taken by it.

of out-of-pocket expenses (including the fees and disbursements of counsel)
incurred by the Administrative Agent in connection with the preparation of the
Credit Documents and the determination or preservation of any rights of the
Administrative Agent, the Other Agents, the Lenders or their respective
Eligible Affiliates under, or the enforcement of, or legal advice in respect of
rights or responsibilities under, the Credit Documents, to the extent that the
Administrative Agent is not promptly reimbursed for such expenses by the
Borrowers on demand.

1.113 EXCULPATION
      -----------
      
     None of the Administrative Agent or any Other Agent shall have any duties
or responsibilities except those expressly set forth in the Credit Documents.
None of the Administrative Agent, any Other Agent nor any of their respective
officers, directors, employees or agents shall be liable for any action taken
or omitted to be taken under or in connection with the Credit Documents, unless
such act or omission constitutes gross negligence or wilful misconduct.  The
duties of the Administrative Agent and the Other Agents shall be mechanical and
administrative in nature; none of the Administrative Agent or any Other Agent
shall have by reason of the Credit Documents a fiduciary relationship with any
Lender and nothing in the Credit Documents, express or implied, is intended to
or shall be construed as to impose upon the Administrative Agent or any Other
Agent any obligation except as expressly set forth therein.  None of the
Lenders shall have any duties or responsibilities to any of the other Lenders
except as expressly set forth in the Credit Documents.  None of the
Administrative Agent or any Other Agent shall be responsible for any recitals,
statements, representations or warranties in any of the Credit Documents or
which may be contained in any other document subsequently received by the
Administrative Agent, any Other Agent or the Lenders from or on behalf of any
Restricted Party or any Independent Subsidiary or for the authorization,
execution, effectiveness, genuineness, validity or enforceability of any of

                                                                   SECTION 11.03


                                    - 144 -




the Credit Documents, and none of the Administrative Agent or any Other Agent
shall be required to make any inquiry concerning the performance or observance
by any Restricted Party or any Independent Subsidiary of any of the terms,
provisions or conditions of any of the Credit Documents.  Each of the Lenders
severally represents and warrants to the Administrative Agent and the Other
Agents that it has made and will continue to make such independent
investigation of the financial condition and affairs of the Restricted Parties
as such Lender deems appropriate in connection with its entering into of any of
the Credit Documents and the making and continuance of any Accommodation
hereunder, that such Lender has and will continue to make its own appraisal of
the credit worthiness of the Restricted Parties and that such Lender in
connection with such investigation and appraisal has not relied upon any
information provided to such Lender by the Administrative Agent or by any Other
Agent.

1.114 RELIANCE ON INFORMATION
      -----------------------

     The Administrative Agent and each Other Agent shall be entitled to rely
upon any writing, notice, statement, certificate, facsimile, telex or other
document or communication believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons, and, with respect to
all legal matters pertaining to the Credit Documents and its duties thereunder,
upon the advice of counsel selected by it.

1.115 KNOWLEDGE AND REQUIRED ACTION
      -----------------------------

     None of the Administrative Agent nor any Other Agent shall be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
(other than the non-payment of any principal, interest or other amount to the
extent the same is required to be paid to the Administrative Agent for the
account of the Lenders) unless the Administrative Agent or such Other Agent has
received notice from a Lender or a Borrower specifying such Default or Event of
Default and stating that such notice is given pursuant to this Section.  In the
event that the Administrative Agent receives such a notice, it shall give
prompt notice thereof to the Lenders, and shall also give prompt notice to the
Lenders of each non-payment of any amount required to be paid to the
Administrative Agent for the account of the Lenders.  The Administrative Agent
shall, subject to Section 11.06, take such action with respect to such Default
or Event of Default as shall be directed by the Lenders in accordance with this
Article; provided that, unless and until the Administrative Agent shall have
received such direction the Administrative Agent may, but shall not be obliged
to, take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall deem advisable in the best interest of
the Lenders; and provided further that the Administrative Agent in any case
shall not be required to take any such action which it determines to be
contrary to the Credit Documents or to any Applicable Law.



   153
                                                                   SECTION 11.06

                                    - 145 -



1.116 REQUEST FOR INSTRUCTIONS
      ------------------------

     The Administrative Agent may at any time request instructions from the
Lenders with respect to any actions or approvals which, by the terms of any of
the Credit Documents, the Administrative Agent is permitted or required to take
or to grant, and the Administrative Agent shall be absolutely entitled to
refrain from taking any such action or to withhold any such approval and shall
not be under any liability whatsoever as a result thereof until it shall have
received such instructions from the Lenders.  No Lender shall have any right of
action whatsoever against the Administrative Agent as a result of the
Administrative Agent acting or refraining from acting under the Credit
Documents in accordance with instructions from the Lenders or the Required
Lenders, as applicable.  The Administrative Agent shall in all cases be fully
justified in failing or refusing to take or continue any action under the
Credit Documents unless it shall have received further assurances to its
satisfaction from the Lenders and their Eligible Affiliates of their
indemnification obligations under Section 11.02 against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take such action, and unless it shall be secured in respect thereof as it may
deem appropriate.

1.117 EXCHANGE OF INFORMATION
      -----------------------

     The Borrowers agree that each Lender, the Administrative Agent and the
Other Agents may provide to the other Lenders or the Administrative Agent or
any Other Agent such information concerning the financial position and property
and operations of the Restricted Parties as, in the opinion of such Lender or
the Administrative Agent, is relevant to the ability of each of the Restricted
Parties to fulfil its respective obligations under or in connection with the
Credit Documents.

1.118 THE ADMINISTRATIVE AGENT AND THE OTHER AGENTS, INDIVIDUALLY
      -----------------------------------------------------------

     With respect to its Commitments, the Accommodation made available by it
and the Credit Documents to which it is a party, each of the Persons which is
the Administrative Agent or an Other Agent and their respective Affiliates
shall have the same rights and powers under the Credit Documents as any other
Lender and may exercise such rights and powers as though such Person were not
the Administrative Agent or an Other Agent or an Affiliate of the
Administrative Agent or an Other Agent, and the term "Lenders" and "Required
Lenders" shall, unless the context clearly otherwise indicates, include each
such Person in its individual capacity.  It is understood and agreed by all of
the Lenders that each of the Persons which is the Administrative Agent or an
Other Agent, either directly or through its Affiliates, from time to time
accepts deposits from, lends money to, provides underwriting, consulting and
advisory services to, and generally engages in banking, securities, advisory
and other related and ancillary businesses with the Restricted Parties and
their Affiliates and Associates otherwise than as a Lender under the Credit
Documents and may continue to do so as if it were not the

   154
                                                                   SECTION 11.08

                                    - 146 -





Administrative Agent or an Other Agent under the Credit Documents and shall
have no duty to account to any of the Lenders with respect to any such
dealings.

1.119 RESIGNATION AND TERMINATION
      ---------------------------

     If at any time (i) the Administrative Agent or any Other Agent shall deem
it advisable, in its sole discretion, it may deliver to each of the Lenders and
the Borrowers written notification of its resignation insofar as it acts on
behalf of the Lenders pursuant to this Article or (ii) the Administrative Agent
or any Other Agent is in default of any of its obligations hereunder and the
Lenders shall deem it advisable, in their sole discretion, they may deliver to
the Administrative Agent or such Other Agent, as the case may be, and the
Borrowers written notification of the termination of the Administrative Agent's
or such Other Agent's, as the case may be, authority to act on behalf of the
Lenders pursuant to this Article.  Any such resignation or termination of the
Administrative Agent is to be effective upon the date of the appointment by the
Lenders of a successor which shall assume all of the rights, powers, privileges
and duties of the Administrative Agent under the Credit Documents, which
appointment shall be promptly made from among the remaining Lenders and written
notice thereof shall be given to the Borrowers concurrently with such
appointment.  The Borrowers shall have the right to approve any successor
Administrative Agent to be appointed by the Lenders as aforesaid at any time
that no Default or Event of Default has occurred and is continuing, provided
that such approval shall not be unreasonably withheld or delayed.  Any such
resignation or termination of any Other Agent is to be effective immediately.
If in the case of resignation by the Administrative Agent no appointment of a
successor Administrative Agent has been made by the Lenders and approved by the
Borrowers within 30 days, the resigning Administrative Agent may make such
appointment without the approval of the Borrowers from among the remaining
Lenders on behalf of the Lenders, and shall forthwith give notice of such
appointment to the Lenders and the Borrowers.

1.1101 ACTIONS BY LENDERS
       ------------------

     (1) Any approval (including without limitation any approval of or
authorization for any amendment to any of the Credit Documents), instruction or
other expression of the Lenders under any of the Credit Documents may be
obtained by an instrument in writing signed in one or more counterparts by the
Required Lenders, or where required by subsection 11.10(3) all of the Lenders
(which instrument in writing, for greater certainty, may be delivered by
facsimile).

     (2) Any approval (including without limitation any approval of or
authorization for any amendment to any of the Credit Documents), instruction or
other expression of the Lenders hereunder may also be included in a resolution
that is submitted to a meeting or adjourned meeting of the Lenders duly called
and held for the purpose of considering the same as hereinafter provided and
shall be deemed to have been obtained if such resolution is passed by the
affirmative vote evidenced in writing of the Required Lenders at a meeting at
which a

   155
                                                                   SECTION 11.10

                                    - 147 -





quorum is present.  A meeting of Lenders may be called by the Administrative
Agent and shall be called by the Administrative Agent upon the request of any
three Lenders.  Every such meeting shall be held in the City of Toronto or at
such other reasonable place as the Administrative Agent may approve.  At least
seven days notice of the time and place of any such meeting shall be given to
the Lenders and shall include or be accompanied by a draft of the resolutions
to be submitted to such meeting, but the notice may state that such draft is
subject to amendment at the meeting or any adjournment thereof.  The Required
Lenders who are present in person or by proxy at the time and place specified
in the notice shall constitute a quorum for the purpose of the transaction of
business.  A person nominated in writing by the Administrative Agent shall be
chairman of the meeting.  Upon every poll taken at any such meeting every
Lender who is present in person or represented by a proxy duly appointed in
writing (who need not be a Lender) shall be entitled to one vote in respect of
each U.S. $1 of its Commitment (or if the Commitments have been terminated each
U.S. $1 of the U.S. Dollar Amount of its outstanding Accommodation).  In
respect of all matters concerning the convening, holding and adjourning of
Lenders' meetings, the form, execution and deposit of instruments appointing
proxies and all other relevant matters, the Administrative Agent may from time
to time make such reasonable regulations not inconsistent with this subsection
11.10(2) as it shall deem expedient and any regulations so made by the
Administrative Agent shall be binding upon the Borrowers, the Administrative
Agent and the Lenders.

    (3)  Notwithstanding subsections 11.10(1) and (2):

    (a)  the consent of all of the Lenders evidenced by an instrument in writing
         or, if all of the Lenders are present at a meeting of Lenders as
         aforesaid, by an affirmative vote of all of the Lenders, will be
         required for (i) any amendment to, postponement of, or discharge of all
         or substantially all of the Security (other than a release of Security
         over any property which a Restricted Party is expressly permitted to
         Dispose of pursuant to the provisions of this Agreement) or any release
         of the Cdn. Borrower from its guarantee forming part of the Security,
         (ii) any reduction to the amount of, or any extension to the date of,
         payment of any principal, interest or fees under this Agreement, (iii)
         any change to or waiver of clauses 9.01(a), (b), (i), (j), (k), (l) or
         (m) as they relate to a Borrower, Sections 9.02 and 9.03 or this
         Subsection, or (iv) any reduction in the percentage specified in the
         definition of Required Lenders or in any percentage of Lenders
         specified in any Credit Document as being required for the Lenders to
         take any action (it being understood that, with the consent of the
         Required Lenders, additional extensions of credit pursuant to this
         Agreement may be included in the determination of the Required Lenders
         on substantially the same basis as the extensions of the Commitments
         are included on the Closing Date);

    (b)  except for any change in a Commitment otherwise expressly provided for
         in this Agreement, the consent of the particular Lender will be
         required for any change in

   156
                                                                   SECTION 11.10

                                    - 148 -





         the Commitment of such Lender (it being understood that neither a
         reallocation of Commitments among Tranches as permitted under this
         Agreement nor waivers or modifications of conditions precedent,
         covenants, Defaults or Events of Default or of a mandatory reduction of
         the total Commitment shall constitute an increase of the Commitment of
         any Lender);

    (c)  the consent of the Administrative Agent will be required for any change
         with respect to the duties or liabilities of the Administrative Agent
         under the Credit Documents; and

    (d)  the consent of an Other Agent will be required for any change with
         respect to the duties or liabilities of such Other Agent under any of
         the Credit Documents.

    (4)  An instrument in writing from the Required Lenders or, where
applicable, all of the Lenders as provided for in subsection 11.10(1) and a
resolution passed pursuant to subsection 11.10(2) ( any such instrument in
writing or resolution being an "APPROVAL INSTRUMENT") shall be binding upon all
of the Lenders, the Other Agents, the Administrative Agent and their respective
Eligible Affiliates, and the Administrative Agent (subject to the provisions for
its indemnity contained in this Agreement) shall be bound to give effect thereto
accordingly.  For greater certainty, to the extent so authorized in the Approval
Instrument, the Administrative Agent shall be entitled (but not obligated) to
execute and deliver on behalf of the Administrative Agent, the Other Lenders,
all of the Lenders and all of their respective Eligible Affiliates, without the
requirement for the execution by any other Person or Persons, any consents,
waivers, documents or instruments (including without limitation any amendment to
any of the Credit Documents) necessary or advisable in the opinion of the
Administrative Agent to give effect to the matters approved by the Required
Lenders or all of the Lenders, as the case may be, in any Approval Instrument.

1.111 PROVISIONS FOR BENEFIT OF LENDERS ONLY
      --------------------------------------

     The provisions of this Article (other than Section 11.07, the last sentence
of Section 11.01 and the last sentence of subsection 11.10(4)) relating to the
rights and obligations of the Lenders, the Other Agents, the Administrative
Agent and their respective Eligible Affiliates inter se shall be operative as
between the Lenders, the Other Agent, the Administrative Agent and their
respective Eligible Affiliates only, and the Borrowers shall not have any rights
under or be entitled to rely for any purposes upon such provisions.

1.121 PARTICIPATIONS, ASSIGNMENTS AND TRANSFERS
      -----------------------------------------

     (1) In addition to any transfer required by Section 9.03 to be made to any
other Lender or required by Applicable Law to be made to any Person, a Lender
may assign or transfer (a "SYNDICATION"), or grant participations (a
"PARTICIPATION") in, or enter into any other arrangement (a "CREDIT
DERIVATIVE") for the purpose of sharing, transferring or otherwise mitigating
its risks with respect to, all or any part of its rights and obligations in
respect of its Commitments or any Accommodation from time to time outstanding
from it to such Persons ("PARTICIPANTS"), at such times and upon such terms as
it may determine, without any obligation to obtain any consent from any
Restricted Party, in accordance with the following provisions:

    (a)  With respect to the grant of any Participation or any Credit
         Derivative:

            (i)    the granting Lender shall remain fully liable for all of its
                   obligations under the Credit Documents to the same extent as
                   if such Participation or Credit Derivative had not been
                   granted;

           (ii)    all amounts payable by the Borrowers to the granting Lender
                   under this Agreement shall be determined as if such Lender
                   had not granted such Participation or Credit Derivative and
                   as if such Lender were funding all Accommodation included in
                   such Participation or Credit Derivative in the same way that
                   it is funding all Accommodation made available by it in which
                   no Participation or Credit Derivative has been granted;

          (iii)    the granting Lender shall administer such Participation or
                   Credit Derivative on behalf of the applicable Participant,
                   and neither such Participant nor any Restricted Party shall
                   have any rights against or obligations to, or deal directly
                   with, each other in respect of such Participation or Credit
                   Derivative; and

           (iv)    the granting Lender shall ensure that its arrangements with
                   respect to any such Participation or Credit Derivative do not
                   require the granting Lender to consult with the applicable
                   Participant with respect to any consents, approvals or votes
                   from such granting Lender relative to any matter except for
                   consents, approvals, amendments or waivers which would (x)
                   extend the final scheduled maturity of any Accommodation in
                   which such Participant is participating or reduce the rate or
                   extend the time for payment of interest or fees thereon or
                   reduce the principal amount thereof, or increase the amount
                   of the Participant's participation over the amount thereof
                   then in effect (it being understood that a waiver of any
                   Default or

                   Commitments shall not constitute a change in the terms of
                   such participation, and that an increase in the available
                   portion of any Commitment of any Lender shall be permitted
                   without the consent of any Participant if the Participant's

                   consent to the assignment or transfer by a Borrower of any of
                   its rights or obligations under this Agreement, or (z)
                   release all or substantially all of the Security (except as
                   expressly provided for in the Credit Documents).

    (b)  with respect to any such Syndication:

            (i)    no such assignment or transfer shall be made at any time that
                   an Event of Default is not continuing unless the applicable
                   assignee or transferee (the "ASSIGNEE") is an Affiliate of
                   the assigning or transferring Lender (the "ASSIGNOR") or is
                   an Eligible Transferee. The term "ELIGIBLE TRANSFEREE" shall
                   mean and include a commercial bank, trust company, insurance
                   company, financial institution, any fund (a "FUND") that
                   invests in bank loans and any other "accredited investor" (as
                   defined in Regulation D of the United States Securities and
                   Exchange Act).  In the case of any Lender that is a Fund, any
                   other Fund which is managed by the same investment advisor of
                   such Lender or by an Affiliate of such investment advisor
                   shall be deemed to be an Affiliate of such Lender for the
                   purposes of this subsection;

           (ii)    at the time of any such assignment or transfer to an Assignee
                   which will, as a result of such assignment or transfer,
                   become a U.S. Lender, which is not already a U.S. Lender and
                   which is not a United States person (as such term is defined
                   in Section 7701(a)(30) of the Code) for United States Federal
                   income tax purposes, the Assignee shall, to the extent
                   legally entitled to do so, provide to the U.S. Borrower in
                   the case of a Lender described in clause (a) or (b) of
                   subsection 5.03(3), the forms described in such clause (a) or
                   (b), as the case may be;

          (iii)    the Assignor shall obtain from the Assignee an undertaking of
                   the Assignee, addressed to the parties to this Agreement (as
                   such parties may be constituted at such time) and
                   substantially in the form of Schedule 24 (the "UNDERTAKING"),
                   whereby the Assignee agrees to be bound by this Agreement in
                   the place and stead of the Assignor to the extent of the
                   rights and obligations of the Assignor in respect of the
                   amount of its Commitments that has been assigned or
                   transferred to the Assignee and the assignment or transfer
                   shall be made by way of an assignment and

   159
                                                                   SECTION 12.01

                   assumption agreement between the Assignor and the Assignee
                   substantially in the form of Schedule 25;

           (iv)    no such assignment or transfer other than an assignment or
                   transfer to another Lender or to any Affiliate of any Lender
                   shall be made to any Person if the Assignor has not received

                   multiple of U.S. $100,000; and

         (xiii)    the Assignor or the Assignee, as the case may be, shall pay
                   to the Administrative Agent at the time of any such
                   assignment or transfer to a Person who is not an Affiliate of

                   Assignee relative to each such assignment or transfer
                   (provided that assignments or transfers to two Affiliated
                   Persons under Tranche 2 who will act as a Cdn. Cross Border
                   Lender and its Affiliated U.S. Cross Border Lender or to two

                   LC Lender and its Affiliated U.S. LC Lender shall be treated
                   as one assignment or transfer to one Assignee).

    (c)  Each of the Borrowers, the Other Agents and the Lenders consents to
         each and every assignment or transfer which may be made on or after the
         date of this Agreement pursuant to this Section, and to the release and
         discharge of each Assignor in accordance with clause (ix) of paragraph
         of this Section.

    (d)  Each Assignee shall be deemed to have confirmed to the Administrative
         Agent, the Other Agents and the Lenders that it has received a copy of
         this Agreement together with such other documents and information as it
         has deemed appropriate to make its own credit analysis and decision to
         acquire such of the rights and obligations of the Assignor as have been
         assigned or transferred to it, and each Assignee agrees that,
         independently and without reliance upon the Administrative Agent, any
         Other Agent, the Assignor or any other Lender and based on such
         documents and information as it shall deem appropriate at the time, it
         will continue to make its own credit decisions in taking or not taking
         actions under this Agreement, and further agrees that it will perform
         in accordance with their terms all of the obligations which by the
         terms of the Credit Documents are required to be performed by it as a
         Lender.

    (e)  Any grant, assignment or transfer pursuant to this Section will not
         constitute a repayment by the applicable Borrower to the granting
         Lender or to the Assignor, as the case may be, of any Accommodation
         included in such assignment or transfer, nor a new advance of such
         Accommodation to such Borrower by the grantee or by the Assignee, as
         the case may be, and the parties acknowledge that the applicable
         Borrower's obligations under this Agreement with respect to any

   162
                                                                   SECTION 12.01

                                    - 154 -





         assigned or transferred Accommodation will continue and not constitute
         new obligations.

    (f)  The Lenders, the Administrative Agent and the Other Agents may disclose
         on a confidential basis to a potential or actual Participant or
         Assignee such information concerning the Restricted Parties, the
         Independent Subsidiaries and the Credit Documents as the Administrative
         Agent, any Other Agent or any Lender may consider to be appropriate in
         connection therewith, provided that such potential or actual
         Participant or Assignee, as the case may be, shall be subject to the
         provisions of Section 12.06.

    (g)  A Borrower may not, and, unless expressly permitted under this
         Agreement, shall not permit any other Restricted Party to, assign or
         transfer all or any of its rights or obligations under any Credit
         Document without the prior written consent of all of the Lenders.

    (h)  Notwithstanding clauses 12.01(1)(b)(v) and 12.01(1)(b)(viii), the
         Administrative Agent and the Cdn. Borrower may consent to an assignment
         or transfer by an Assignor which would have the effect of adjusting the
         Commitments under the Tranches of a Credit by all or a portion of the
         amount assigned or transferred by each Assignor having regard to the
         wish of the Assignor to become a Lender under a different Tranche of
         such Credit with respect to the amount so assigned or transferred than
         the Tranche under which such amount was held by the Assignor.

    (i)  To the extent that an assignment or transfer of all or any portion of a
         Lender's Commitments and related outstanding Accommodation by way of a
         Participation or a Credit Derivative pursuant to subsection 12.01(a) or
         pursuant to this subsection would, at the time of such assignment or
         transfer, result in increased costs under Section 5.03 or Section 5.04
         in excess of those being charged by the applicable Assignor prior to
         such assignment or transfer, then the applicable Borrower, in
         accordance with and pursuant to the other provisions of this Agreement,
         shall not be obligated to pay such excess increased costs (although the
         Borrowers, in accordance with and pursuant to the other provisions of
         this Agreement, shall be obligated to pay the costs which are not in
         excess of those being charged by the applicable Assignor prior to such
         assignment or transfer and any subsequent increased costs of the type
         described above resulting from changes after the date of the such
         assignment or transfer).

    (2) Any Lender may pledge its interests in the Credit Documents in the
ordinary course of its business including to the United States Federal Reserve
or any other similar Governmental Authority and, with the consent of the
Administrative Agent, any Lender that is a

   163
                                                                   SECTION 12.01

                                    - 155 -





Fund may pledge all or any portion of its interests in the Credit Documents to
its trustee in support of its obligations to its trustee.

1.122 WAIVER
      ------

     No delay on the part of the Administrative Agent, any Other Agent or any
Lender in exercising any right or privilege under any Credit Document shall
operate as a waiver of such right or privilege, and no waiver of any Default or
Event of Default shall operate as a waiver of such Default or Event of Default
unless made in writing and signed by an authorized officer of the
Administrative Agent.  No written waiver shall preclude the exercise by the
Administrative Agent, any Other Agent or any Lender of any right, power or
privilege under any Credit Document other than in respect of the specific
action or inaction covered by such waiver and strictly in accordance with the
terms of such waiver, or extend to or apply to any other Default or Event of
Default.  No Lender shall be deemed to have waived, by reason of making
available any Accommodation under this Agreement, any Default or Event of
Default which has arisen by reason of any representation or warranty made or
deemed to have been made in any Credit Document proving to be false or
misleading.

      -------------------------

such transfer, such transfer increases the amount for which any Borrower is

pursuant to Section 5.04 compared to such amounts existing prior to such
transfer, such Lender shall not be entitled to receive from any Borrower, and
no Borrower shall be obligated to pay, such excess increased costs (although

Agreement, shall be obligated to pay the costs which are not in excess of those
being charged by such Lender prior to such transfer and any subsequent
increased costs of the type described above resulting from changes after the
date of such transfer).

     Each of the Lenders will maintain on a confidential basis (except as
otherwise permitted under the Credit Documents or as required by Applicable Law)
all information relating to the Borrowers and their Subsidiaries provided to it
under the Credit Documents by such Borrower; provided, however, that a Lender
may share such information with those of its Affiliates which are lending
institutions (but for greater certainty not with any such Affiliates which are
brokers or investment dealers unless any such Affiliate is one institution which
has both a lending division and a broker dealer division, in which case such
information may not be shared with any members of the broker dealer division)
and provided further that this Section shall not apply to any information which

Administrative Agent and the Lenders to enforce any of their rights under any of
the Credit Documents.

confirming that, other than in respect of their interest in the shares of any
Independent Subsidiary subject to the Lien of the Security or in respect of any
claims made by a Restricted Party against an Independent Subsidiary as a
consequence of any dealings or relationships between such Persons, none of the
