               Compliance Period to the date of the Acquisition of such Acquired
               Subsidiary, by (y) 365; provided, however, that any increase in
               EBITDA as a result of the adjustments described in this Section
               1.5 made on the basis of reviewed financial statements pursuant
               to subclause (ii)(C) shall not exceed $10,000,000 (U.S.) for any
               Compliance Period.

     (b)  For purposes of determining any Applicable Fee Amount or any
          Applicable Margin or calculating JM's compliance with Sections 8.10,
          8.11 and 8.12, such determination and calculation shall exclude the
          financial results and condition of each Unrestricted Subsidiary.

          Dollar amount set forth opposite such Bank's name on Schedule 2.1
          under the heading "Commitment" (such amount, as the same may be
          reduced under Section 2.9 or reduced or increased as a result of one
          or more assignments under Section 11.8, such Bank's "Commitment");
          provided, however, that, after giving effect to any Borrowing of
          Revolving Loans, the Canadian Dollar Equivalent Amount of all
          outstanding Revolving Loans shall not at any time exceed the Aggregate
          Commitment. Within the limits of each Bank's Commitment, and subject
          to the other terms and conditions hereof, the Borrower may borrow
          Revolving Loans under this Section 2.1(a), prepay such Loans under
          Section 2.10 and reborrow under this Section 2.1(a).

     (b)  Borrower's Request for Increased Commitment. The Borrower may request
          -------------------------------------------                          
          an increase in the Aggregate Commitment upon written notice to the
          Agent, such notice to be given to the Agent on or before the first
          anniversary date of the Closing Date.  Neither the Agent nor any of
          the Banks shall be under any obligation to provide all or any portion
          of such requested increase in the Aggregate Commitment but upon
          receipt of any such notice from the Borrower the Agent shall use
          commercially reasonable efforts to seek additional commitments from
          the existing Banks or to seek commitments from other financial
          institutions in amounts sufficient to total the requested increased
          Commitment.  The Agent shall notify the Borrower whether or not it has
          been able to do so.

2.2    Loan Accounts.

          or records maintained by the Agent, and each Bank shall be conclusive
          evidence, absent manifest error, of the amount of the Loans made by
          the Banks to the Borrower, and the interest and payments thereon.  Any
          failure so to record or any error in doing so shall not, however,
          limit or otherwise affect the obligation of the Borrower hereunder to
          pay any amount owing with respect to the Loans.

     (b)  Upon the request of any Bank made through the Agent, the Loans (other
          than BA Advances) made by such Bank shall be evidenced by one or more
          Notes, which the Borrower shall execute and deliver, as applicable,
          instead of or in addition to loan accounts. Each such Bank shall
          endorse on the schedules annexed to its Note(s) the date, amount and
          maturity of each Loan (other than a BA Advance) made by it and the
          amount and Applicable Currency of each payment of principal made by
          the Borrower with respect thereto. Each such Bank is irrevocably
          authorized by the Borrower to endorse its Note(s) and each Bank's
          record shall be conclusive evidence absent manifest error; provided,
                                                                     ---------
          however, that the failure of a Bank to make, or an error in making, a

          affect the obligations of the Borrower hereunder or under any such
          Note to such Bank.

          form of a Notice of Borrowing (which notice must be received by the
          Agent (i) prior to 11:00 am. (Toronto time) three Business Days prior
          to the requested Borrowing Date, in the case of LIBOR Loans; (ii)
          prior to 12:00 p.m. (Toronto time) two Business Days prior to the
          requested Borrowing Date, in the case of BA Advances;  and (iii) prior
          to 11:00 a.m. (Toronto time) on the requested Borrowing Date in the
          case of any other Loan, specifying:

          (A)  except in the case of BA Advances, the amount of the Borrowing,
               which shall be in a Minimum Amount;

          (D)  in the case of LIBOR Loans, the duration of the initial Interest
               Period applicable to such LIBOR Loans included in such notice,
               subject to the provisions of the definition of "Interest Period"
               herein. If the Notice of Borrowing fails to specify the duration
               of the Interest Period for any Borrowing comprised of LIBOR
               Loans, such Interest Period shall be one month; and

          (E)  in the case of BA Advances, the aggregate face amount (which
               shall be in a Minimum Amount) and term (subject to the provisions
               of Article III) of any drafts or bills of exchange to be issued
               by the Borrower in conjunction with a BA Advance.

          Upon receipt of any Notice of Borrowing of Revolving Loans, the Agent
          will promptly notify each Bank thereof and of the amount of such
          Bank's Pro Rata Share of the Borrowing (expressed in the Applicable
          Currency of the Borrowing).

     (b)  Each Bank shall accept its Pro Rata Share of Bankers' Acceptances and
          purchase its own Bankers' Acceptances as provided for in Article III
          below.

     (c)  Each Bank will make the amount of its Pro Rata Share of each Borrowing
          of Revolving Loans (other than BA Advances, as to which Section 3.2
          shall apply) available to the Agent for the account of the Borrower at
          the Agent's Payment Office on the Borrowing Date requested by the
          Borrower's Designee in Same Day Funds and in the requested currency by
          2:00 p.m. (Toronto time). The proceeds of all such Borrowings will
          then be made available to the Borrower by the Agent at such office by
          crediting the account of the Borrower with the aggregate of the
          amounts made available to the Agent by the Banks and in like funds as
          received

          customary fees for such wire transfer, unless on the date of the
          Borrowing all or any portion of the proceeds thereof shall than be
          required to be applied to the repayment of any outstanding Loans, in
          which case such proceeds or portion thereof shall be applied to the
          payment of such Loans.

2.4     Conversion and Continuation Elections.
        ------------------------------------- 

     (a)  The Borrower's Designee may, upon irrevocable written notice in
          accordance with subsection 2.4(b) elect, as of any Business Day, in
          the case of Canadian Dollar Advances or U.S. Dollar Loans or on the
          maturity date of Loans in the form of outstanding maturing Bankers'
          Acceptances or as of the last day of the applicable Interest Period,
          in the case of any LIBOR Loans, to continue or convert any such Loans
          (or any part thereof in an amount not less than a Minimum Amount) into
          Loans of any other Type; provided, that if at any time the aggregate
                                   ---------                                  
          amount of LIBOR Loans in respect of any Borrowing is reduced, by
          payment, prepayment, or conversion of part thereof to be less than
          $1,000,000 (U.S.), such LIBOR Loans shall automatically convert into
          U.S. Dollar  Loans, and on and after such date the right of the
          Borrower to continue such Loans as, and convert such Loans into, LIBOR
          Loans shall terminate.

     (b)  Each such conversion and continuation of Revolving Loans shall be made
          upon delivery by the Borrower's Designee of a Notice of
          Conversion/Continuation to the Agent. Each such Notice of
          Conversion/Continuation must be received by the Agent (i) not later
          than 11:00 a.m. (Toronto time) three Business Days in advance of the
          Conversion/Continuation Date, if any Loans are to be converted into or
          continued as LIBOR Loans; (ii) not later than 12:00 p.m. (Toronto
          time) two Business Days in advance of the Conversion/Continuation
          Date, if any Loans are to be converted into or continued as BA
          Advances (such continuation of a BA Advance also being referred to
          herein as a "rollover");  and (iii) not later than 12:00 p.m. (Toronto
          time) on the Conversion/Continuation Date, if the Loans are to be
          converted into Canadian Dollar Advances or U.S. Dollar Loans,
          specifying:

          (A)  the proposed Conversion/Continuation Date;

          (B)  the aggregate amount of Loans to be converted or continued;

          (C)  the Type of Loans resulting from the proposed conversion or
               continuation; and

          (D)  other than in the case of conversions into BA Advances (as to
               which the provisions of subsection 2.4(d) shall also apply),
               Canadian Dollar Advances or U.S. Dollar Loans, the duration of
               the requested Interest Period.

                                      23
<PAGE>
 
     (c)  If upon the expiration of any Interest Period applicable to LIBOR
          Loans, the Borrower's Designee has failed to select timely a new
          Interest Period to be applicable to such LIBOR Loans, or if any Event
          of Default then exists, the Borrower's Designee shall be deemed to
          have elected to convert such LIBOR Loans into U.S. Dollar Loans
          effective as of the expiration date of such Interest Period.

     (d)  A conversion from a BA Advance to another Type of Loan or a rollover
          of a BA Advance may occur only on the maturity date of the relevant
          Bankers' Acceptance and subject to the other terms of this Agreement.
          In connection with the maturity of Bankers' Acceptances, the Borrower
          shall do one or a combination of the following:

          (i)  effect a rollover of such BA Advance by the Borrower's Designee
               delivering a Notice of Conversion/Continuation to the Agent in
               accordance with subsection 2.4(b) in which case the Borrower
               shall, on the relevant maturity date of the Bankers' Acceptances
               comprising such BA Advance, pay the Agent on behalf of the Banks
               an amount equal to the amount by which the face amount of the
               maturing Bankers' Acceptances exceeds the BA Proceeds of any
               Bankers' Acceptances newly issued in connection with such
               rollover (in respect of which the Borrower's Designee must
               separately deliver a Notice of Borrowing and comply with Article
               III);

          (ii) effect a conversion of such BA Advance into another Type of Loan
               pursuant to the foregoing subsections by obtaining a Loan, the
               proceeds of which are sufficient to pay the face amount of such
               maturing Bankers' Acceptances; or

         (iii) pay to the Agent an amount equal to the face amount of the
               Bankers' Acceptances comprising such BA Advance on their
               maturity.

          If the Borrower's Designee fails to so notify the Agent, or the
          Borrower fails to so pay the Bankers' Acceptances, the BA Advance
          shall be converted to a Canadian Dollar Advance on the maturity date
          of such Bankers' Acceptances.

     (e)  The Borrower may effect a partial rollover of a BA Advance or a
          partial conversion into a BA Advance with the remainder of such
          maturing BA Advance being either converted or repaid in accordance
          with the provisions of this Agreement subject in all cases to the
          Borrower complying with the provisions of this Agreement.

     (f)  The Agent will promptly notify each Bank of its receipt of a Notice of
          Conversion/Continuation of Revolving Loans, or, if no timely notice is
          provided by the Borrower's Designee in respect of a LIBOR Loan or a BA
          Advance, the 

                                      24
<PAGE>
 
          Agent will promptly notify each Bank of the details of any automatic
          conversion. All conversions and continuations of Revolving Loans shall
          be made ratably according to the respective outstanding principal or
          face amounts of the Loans with respect to which the notice was given
          held by each Bank.

     (g)  Unless the Majority Banks otherwise consent, during the existence of
          an Event of Default, neither the Borrower nor the Borrower's Designee
          may elect to have any Borrowing hereunder nor to have any Loan
          continued, rolled over or converted into another Type of Loan
                                                                       
          (provided that during the existence of an Event of Default until the
          ---------                                                           
          Agent exercises any of its remedies referred to in Section 9.2, LIBOR
          Loans may be converted into U.S. Dollar Loans and BA Advances on
          maturity may be converted into Canadian Dollar Advances).

2.7     Currency Exchange Fluctuations.  Subject to Section 4.4, if on any
        ------------------------------                                    
Computation Date, the Agent shall have determined that the Canadian Dollar
Equivalent Amount of the aggregate principal amount of all Revolving Loans
outstanding exceeds the Aggregate Commitment by more than $375,000 (Cdn.), due
to a change in applicable rates of exchange between U.S. Dollars and Canadian
Dollars, then the Agent shall give notice to the Borrower's Designee that a
         ----                                                              
prepayment is required under this Section, and the Borrower agrees that it shall
make prepayments of Loans not later than the Business Day following the
Borrower's Designee's receipt of such notice such that, after giving effect to
such prepayment the aggregate Canadian Dollar Equivalent Amount of all Revolving
Loans does not exceed the Aggregate Commitment.

2.8     [INTENTIONALLY DELETED].
        ----------------------- 

2.9     Voluntary Termination or Reduction of Commitments. The Borrower may,
        -------------------------------------------------                   
upon not less than three Business Days' prior notice from the Borrower's
Designee to the Agent, terminate the Commitments, or permanently reduce the
Commitments by an aggregate minimum amount of at least $1,000,000 (Cdn.) unless,
                                                                         ------ 
after giving effect thereto and to any prepayments of any Loans made on the
effective date thereof, (a) the Canadian Dollar Equivalent Amount of all
Revolving Loans would exceed the Aggregate Commitment then in effect.  Once
reduced in accordance with this Section 2.9, the Commitments may not be
increased. Any reduction of the Commitments shall be applied to each Bank
according to its Pro Rata Share.  All accrued facility fees to, but not
including, the effective date of any termination of the Commitments shall be
paid on the effective date of such termination. The Agent shall promptly forward
a copy of any such notice received under this subsection 2.9 to each of the
Banks.

2.10    Optional Prepayments. Subject to Section 4.4, the Borrower may, at any
        --------------------                                                  
time or from time to time, upon notice from the Borrower's Designee to the
Agent, ratably prepay Revolving Loans, other than BA Advances, in whole or in
part for an amount not less than the applicable Minimum Amount.  The Borrower's
Designee shall deliver a notice of prepayment in 

                                      25
<PAGE>
 
accordance with Section 11.2 to be received by the Agent (i) not later than
12:00 p.m. (Toronto time) at least three Business Days in advance of the
prepayment date if the Loans to be prepaid are LIBOR Loans and (ii) no later
than 11:00 a.m. (Toronto time) on the prepayment date if the Loans to be repaid
are U.S. Dollar Loans or Canadian Dollar Advances. Such notice of prepayment
shall specify the date and amount of such prepayment and whether such prepayment
is of Canadian Dollar Advances, U.S. Dollar Loans, LIBOR Loans or any
combination thereof. Such notice shall not thereafter be revocable by the
Borrower's Designee or by the Borrower. The Agent will promptly notify each Bank
thereof and of such Bank's Pro Rata Share of such prepayment. If such notice is
given by the Borrower's Designee, the Borrower shall make such prepayment and
the payment amount specified in such notice shall be due and payable on the date
specified therein, together with (other than interest in the case of U.S. Dollar
Loans or Canadian Dollar Advances, which interest shall be payable in full on
the last day of the then current calendar quarter) accrued interest to each such
date on the amount prepaid and any amounts required pursuant to Section 4.4.

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

2.12     Repayment of the Revolving Loans.
         ---------------------------------

     (a)  The Borrower shall repay to the Agent for the account of the Banks on
          the Revolving Termination Date the aggregate principal amount of
          Revolving Loans made to the Borrower and outstanding on such date,
          together with all other outstanding or accrued amounts (whether for
          interest, fees, expenses or otherwise)

     (b)  At the option of the Borrower, upon written notice by the Borrower's
          Designee to the Agent to be given not more than 120 days but not less
          than thirty (30) days prior to the then applicable Revolving
          Termination Date, the Borrower's Designee may request that the
          Revolving Termination Date be extended by successive one-year periods;
          provided, however, that each such one-year extension shall require the
          unanimous approval of all of the Banks (such approval to be within the
          sole discretion of each Bank) and the written consent of each Loan
          Party; and provided further that if any Bank shall decline to approve
          of any such extension, the Borrower's Designee may (i) on or prior to
          the then applicable Revolving Termination Date, obtain a Replacement
          Bank to acquire and assume all or part of the Loans and Commitment of
          such non-consenting Bank in accordance with Section 4.8, or (ii)
          subject to repayment in full on or prior to the then applicable
          Revolving Termination Date of all Obligations then owing to each such
          non-consenting Bank, request that the Revolving Termination Date be
          extended only with respect to such Banks as have consented to such
          extension. The Borrower acknowledges and agrees that (A) no Bank shall
          have any obligation to increase its Commitment hereunder or otherwise
          acquire or assume all or any part of any other Bank's Loans or
          Commitment, whether in connection with an extension of the Revolving
          Termination Date pursuant to this subsection (b) or otherwise, and (B)
          in the event that some but not all of the Banks consent to an
          extension of the Revolving Termination Date pursuant this subsection
          (b) and the Borrower's Designee requests that the Revolving
          Termination Date be extended with respect 

                                      26
<PAGE>
 
          to such consenting Banks only, the Aggregate Commitment shall be
          automatically reduced to an amount equal to the combined Commitments
          of the remaining Banks.

2.13      Interest.
          -------- 

     (a)  Each Revolving Loan (other than BA Advances) shall bear interest on
          the outstanding principal amount thereof from the applicable Borrowing
          Date at a rate per annum equal to the Adjusted Prime Rate for Canadian
          Dollar Advances, the Base Rate for U.S. Dollar Loans, and the Offshore
          Rate for LIBOR Loans (and subject to the Borrower's right to convert
          to another Type of Loans under Section 2.4), plus in each case the
                                                       ----                 
          Applicable Margin.

     (b)  Interest on each Revolving Loan (other than BA Advances) shall be
          calculated on the daily outstanding balance thereof at the applicable
          interest rate (referred to in subsection 2.13(a) above) and paid by
          the Borrower (i) in the case of LIBOR Loans on each Interest Payment
          Date and (ii) in the case of Canadian Dollar Advances and U.S. Dollar
          Loans on the last day of the then current calendar quarter. Accrued
          interest shall also be paid on the date of any prepayment or repayment
          of LIBOR Loans under Section 2.7 or 2.10 attributable to the portion
          of the Loans so prepaid or repaid and upon payment (including
          prepayment) of LIBOR Loans in full thereof and, during the existence
          of any Event of Default, interest shall be paid by the Borrower on
          demand of the Agent.

     (c)  Notwithstanding subsection (a) of this Section, if any amount of
          principal of or interest on any Loan payable by the Borrower, or any
          other amount payable by the Borrower hereunder or under any other Loan
          Document is not paid in full when due (whether at stated maturity, by
          acceleration, demand or otherwise), the Borrower agrees to pay
          interest on such unpaid principal or other amount, from the date such
          amount becomes due until the date such amount is paid in full, and
          after as well as before any entry of judgment thereon to the extent
          permitted by law, payable on demand, at a rate per annum equal to the
          interest rate otherwise applicable thereto plus 2% per annum.
                                                     ----              

     (d)  Anything herein to the contrary notwithstanding, the obligations of
          the Borrower to any Bank hereunder shall be subject to the limitation
          that payments of interest shall not be required for any period for
          which interest is computed hereunder, to the extent (but only to the
          extent) that contracting for or receiving such payment by such Bank
          would be contrary to the provisions of any law applicable to such Bank
          limiting the highest rate of interest that may be lawfully contracted
          for, charged or received by such Bank, and in such event the Borrower
          shall pay such Bank interest at the highest rate permitted by
          applicable law.  Without limiting the generality of the foregoing, in
          no event shall the aggregate "interest", (as that term is defined in
          Section 347 of the Criminal Code (Canada), as the same may be amended,
          replaced or re-enacted from time to time,) payable in respect of the
          Loans and other Obligations hereunder exceed the effective annual rate
          of interest 

                                      27
<PAGE>
 
          on the "credit advanced", as defined therein, lawfully permitted under
          that section. The effective annual rate of interest shall be
          determined in accordance with Canadian generally accepted accounting
          principles and actuarial practices and principles over the term of the
          revolving term facility established hereby and, in the event of
          dispute, a certificate of a Fellow of the Canadian Institute of
          Actuaries appointed by the Agent (such appointee to be acceptable to
          the Borrower, acting reasonably) shall be conclusive for the purposes
          of such determination. Notwithstanding anything to the contrary
          contained in this Agreement, the Borrower in no event shall be obliged
          to make payments of interest in excess of any amount or rate which
          would be prohibited by law or would result in the receipt by the Agent
          or any Bank of interest at a criminal rate (as such terms are
          construed under the Criminal Code Canada)

2.14
     (a)  Arrangement Fee. The Borrower shall pay an arrangement fee to the
          ---------------                                                  
          Arranger for the Arranger's own account in accordance with the terms
          of a fee letter agreement between the Borrower and the Agent dated
          June 9, 1998 (the "Fee Letter");

     (b)  Facility Fees. The Borrower shall pay to the Agent, for the account of
          -------------                                                         
          each Bank, a facility fee in Canadian Dollars on the Aggregate
          Commitment, computed on a quarterly basis in arrears on the last
          Business Day of each calendar quarter, as calculated by the Agent, at
          a rate per annum equal to the Applicable Fee Amount. Such facility fee
          shall be payable regardless of utilization of the Commitments and
          shall accrue from the Closing Date to the Revolving Termination Date
          and shall be due and payable quarterly in arrears on the last Business
          Day of each calendar quarter commencing on June 30, 1998, through the
          Revolving Termination Date, with the final payment to be made on the
          Revolving Termination Date; provided that, in connection with any
                                      --------                             
          termination of Commitments under Section 2.9, the accrued facility fee
          calculated for the period ending on such date shall also be paid on
          the date of termination. The facility fees provided in this subsection
          shall accrue at all times after the above-mentioned commencement date,
          including at any time during which one or more conditions in Article V
          are not met.

     (c)  BA Stamping Fees. The Borrower shall pay to each Bank an acceptance or
          ----------------                                                      
          stamping fee determined in accordance with the pricing grid attached
          as Annex 1 hereto upon issuance by the Borrower and acceptance by such
          Bank of each Bankers' Acceptance, such fee to be calculated on the
          undiscounted face amount of each Bankers' Acceptance accepted by such
          Bank hereunder.  Such fee shall be paid upon the issuance by the
          Borrower and the acceptance by each Bank of each Bankers' Acceptance
          (by means of being deducted when determining the applicable BA
          Proceeds) and shall be based on the term of the applicable Bankers'
          Acceptance (computed for the period of time commencing from the date
          of acceptance thereof to but not including the date of maturity of
          such Bankers' Acceptance) on the basis of a 365 or 366 day year, as
          the case may be.

2.15      Computation of Fees and Interest.
          -------------------------------- 

     (a)  All computations of interest for Canadian Dollar Advances, U.S. Dollar
          Loans and all fees hereunder shall be made on the basis of a year of
          365 or 366 days, as the case may be, and actual days elapsed. All
          computations of interest on LIBOR Loans shall be made on the basis of
          a 360-day year and actual days elapsed (which results in more interest
          being paid than if computed on the basis of a 365-day year). Interest
          and fees shall accrue during each period during which interest or such
          fees are computed from the first day thereof to the last day thereof.

     (b)  Each determination of an interest rate or a U.S. or Canadian Dollar
          Equivalent Amount by the Agent shall be conclusive and binding on the
          Borrower and the Banks in the absence of manifest error.

     (c)  For the purposes of this Agreement, whenever any interest is
          calculated on the basis of a period of time (the "shorter period")
          other than a calendar year (whether on the basis of 360 days or
          otherwise) (referred to below as the "first rate") the annual rate of
          interest to which the first rate is equivalent, for purposes of the
          Interest Act (Canada), is the first rate multiplied by the actual
          number of days in the calendar year, (whether 365 or 366 as the case
          may be) in which such calculation is to be made and divided by the
          number of days in the shorter period.  It is understood and agreed by
          the Borrower and the Agent and Banks that, for purposes of this
          Agreement, the deemed re investment principle shall not apply to any
          calculation of interest payable under this Agreement or any Notes.

2.16      Payments by the Borrower.
          ------------------------ 

     (a)  All payments to be made by the Borrower shall be made without set-off,
          recoupment or counterclaim. Except as otherwise expressly provided
          herein, all payments by any Loan Party shall be made to the Agent for
          the account of the Banks at the Agent's Payment Office in U.S. Dollars
          for LIBOR Loans and U.S. Dollar Loans or Canadian Dollars for BA
          Advances and Canadian Dollar Advances and otherwise in the Applicable
          Currency.  Such payments shall be made in Same Day Funds, no later
          than 2:00 p.m. (Toronto Time) on the date specified herein. Any
          payment which is received by the Agent later than 2:00 p.m. (Toronto
          time), shall be deemed to have been received on the following Business
          Day and any applicable interest or fee shall continue to accrue.  The
          Agent will promptly, upon receipt of same, distribute to each Bank its
          Pro Rata Share (or other applicable share as expressly provided
          herein) of such payment in like funds received.

     (b)  Subject to the provisions set forth in the definition of "Interest
          Period" herein, whenever any payment is due on a day other than a
          Business Day, such payment shall be made on the following Business
          Day, and such extension of time shall in such case be included in the
          computation of interest or fees, as the case may be.

                                      29
<PAGE>
 
     (c)  Unless the Agent receives notice from the Borrower or the Borrower's
          Designee prior to the date on which any payment is due to the Banks
          that the Borrower will not make such payment in full as and when
          required, the Agent may assume that the Borrower has made such payment
          in full to the Agent on such date in Same Day Funds and the Agent may
          (but shall not be so required), in reliance upon such assumption,
          distribute to each Bank on such due date an amount equal to the amount
          then due such Bank. If and to the extent the Borrower has not made
          such payment in full to the Agent, each Bank shall repay to the Agent
          on demand such amount distributed to such Bank, together with interest
          thereon at the Federal Funds Rate for each day from the date such
          amount is distributed to such Bank until the date repaid.

2.17      Payments by the Banks to the Agent.
          ---------------------------------- 

     (a)  Unless the Agent receives notice from a Bank on or prior to the Loan
          Availability Date or, with respect to any Borrowing after the Loan
          Availability Date, at least one Business Day prior to the date of such
          Borrowing, that such Bank will not make available as and when required
          hereunder to the Agent, for the account of the Borrower the amount of
          that Bank's Pro Rata Share of the Borrowing, the Agent may assume that
          each Bank has made such amount available to the Agent in Same Day
          Funds on the Borrowing Date and the Agent may (but shall not be so
          required), in reliance upon such assumption, make available to the
          Borrower on such date a corresponding amount. If and to the extent any
          Bank shall not have made its full amount available to the Agent in
          Same Day Funds and the Agent in such circumstances has made available
          to the Borrower such amount, that Bank shall on the Business Day
          following such Borrowing Date make such amount available to the Agent,
          together with interest at the Federal Funds Rate for each day during
          such period. A notice of the Agent submitted to any Bank with respect
          to amounts owing under this subsection 2.17(a) shall be conclusive,
          absent manifest error. If such amount is so made available, such
          payment to the Agent shall constitute such Bank's Loan on the date of
          Borrowing for all purposes of this Agreement. If such amount is not
          made available to the Agent on the Business Day following the
          Borrowing Date, the Agent will notify the Borrower's Designee of such
          failure to fund and, upon demand by the Agent, the Borrower shall pay
          such amount to the Agent for the Agent's account, together with
          interest thereon for each day elapsed since the date of such
          Borrowing, at a rate per annum equal to (except in the case of BA
          Advances) the interest rate applicable at the time to the Loans
          comprising such Borrowing and in the case of BA Advances, at a rate
          per annum equal to the sum of the CDOR BA Rate and BA Stamping Fee
          used to determine the amount of BA Proceeds of such BA Advances.

     (b)  The failure of any Bank to make any Loan on any Borrowing Date shall
          not relieve any other Bank of any obligation hereunder to make a Loan
          on such Borrowing Date, but no Bank shall be responsible for the
          failure of any other Bank); to make the Loan to be made by such other
          Bank on any Borrowing Date.

2.18    Sharing of Payments, Etc.  If, other than as expressly provided
        -------------------------                                      
elsewhere herein, any Bank shall obtain on account of the Loans made by it any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of the other Banks; provided, however,
                                                          --------  ------- 
that if all or any portion of such excess payment is thereafter recovered from
the purchasing Bank, such purchase shall to that extent be rescinded and each
other Bank shall repay to the purchasing Bank the purchase price paid therefor,
together with an amount equal to such paying Bank's ratable share (according to
the proportion of (i) the amount of such paying Bank's required repayment to
(ii) the total amount so recovered from the purchasing Bank) of any interest or
other amount paid or payable by the purchasing Bank in respect of the total
amount so recovered. Each Loan Party agrees that any Bank so purchasing a
participation from another Bank may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 11.10) with respect to such participation as fully as if such Bank
were the direct creditor of such Loan Party in the amount of such participation.
The Agent will keep records (which shall be conclusive and binding in the
absence of manifest error) of participations purchased under this Section and
will in each case notify the Banks following any such purchases or repayments.

2.19      The Borrower's Designee.
          ----------------------- 

     (a)  The Borrower hereby irrevocably appoints, designates and authorizes
          the Borrower's Designee to take such action on its behalf under the
          provisions of this Agreement and each other Loan Document and to
          exercise such powers and perform such duties as are expressly
          delegated to it by the terms of this Agreement or any other Loan
          Document, together with such powers as are reasonably incidental
          thereto. The Borrower's Designee may execute any of its duties under
          this Agreement or any other Loan Document by or through agents,
          employees or attorneys-in-fact.

     (b)  The Borrower's Designee shall promptly forward to the Agent or the
          Borrower, as appropriate, all notices, certificates, financial
          statements and reports received by it in the performance of its duties
          hereunder.

     (c)  The Borrower may, upon 30 days' notice to and with the consent of the
          Agent (which consent shall not be unreasonably withheld), appoint
          another person to act as Borrower's Designee and upon such appointment
          such successor Borrower's Designee shall succeed to all the
          appointment, powers and duties of the retiring Borrower's Designee and
          the term "Borrower's Designee" shall mean such successor designee and
          the retiring Borrower's Designee's rights, powers and duties as
          Borrower's Designee shall be terminated.

     (d)  The Borrower's Designee shall perform its duties hereunder and under
          the other Loan Documents on behalf of the Borrower. The action of the
          Borrower's Designee shall in each case bind the Borrower, and any
          action taken by the 

                                      31
<PAGE>
 
          Borrower's Designee in the name of the Borrower pursuant to this
          Agreement or any other Loan Document shall bind the Borrower, whether
          or not such action has been duly authorized by the Borrower.

     (e)  Any agreement of the Agent and the Banks herein with respect to the
          Borrower's Designee is solely for the convenience and at the request
          of the Borrower. The Agent and the Banks shall be entitled to rely on
          the authority of any Person purporting to be a Person authorized by
          the Borrower to act on behalf of the Borrower's Designee and the Agent
          and the Banks shall not have any liability to the Borrower or other
          Person on account of any action taken or not taken by the Agent or the
          Banks in reliance thereon.

     (f)  Nothing contained in this section 2.19 and no exercise of powers by
          the Borrower's Designee shall relieve the Borrower from its
          indebtedness, liabilities and obligations to the Agent and the Banks
          hereunder.

                                  -----------

[ORIGINAL ARTICLE III INTENTIONALLY DELETED]

3.1    Bankers' Acceptances
       --------------------

     (a)  No Bank shall accept any bill of exchange drawn by the Borrower to be
          a Bankers' Acceptance hereunder which:

         (i)   is drawn on or which matures on a day which is not a Business
               Day;

         (ii)  matures subsequent to the Revolving Termination Date;

         (iii) has a term less than 30 or exceeding 180 days;

         (iv)  is denominated in any currency other than Canadian Dollars;

         (v)   is not in an applicable Minimum Amount;

         (vi)  is not in the form used by the Bank from time to time in the
               normal course of its business; or

         (vii) in respect of which the Borrower has not then paid the
               applicable acceptance or stamping fee.

     (b)  The Borrower hereby waives presentment for payment and any other
          defence to payment of any amounts due to any Bank in respect of
          Bankers' Acceptances and renounces, and shall not claim or request or
          require such Bank to claim, any days of grace for the payment of any
          Bankers' Acceptances.

                                      32
<PAGE>
 
     (c)  All Bankers' Acceptances accepted by each Bank shall be purchased by
          such Bank at the applicable CDOR BA Rate from the Borrower for an
          amount equal to the BA Proceeds.  Any Bank may at any time and from
          time to time hold, sell, rediscount or otherwise dispose of any or all
          Bankers' Acceptances accepted and purchased by it.

     (d)  The Borrower hereby unconditionally agrees to pay to each Bank to such
          address as it may direct on the maturity date (whether at stated
          maturity, by acceleration hereunder or otherwise) of each Bankers'
          Acceptance accepted by such Bank the aggregate undiscounted face
          amount of each then maturing Bankers' Acceptance and in this regard,
          the Borrower hereby authorizes each Bank to debit any account of the
          Borrower with such Bank with the amount(s) required to pay the full
          undiscounted face amount of such Bankers' Acceptance, notwithstanding
          the fact that such Bankers' Acceptance may be held by such Bank in its
          own right at maturity.  The obligation of the Borrower to reimburse
          and pay each Bank for then maturing Bankers' Acceptances may be
          satisfied (provided no Event of Default has occurred and is subsisting
          or no event has occurred which, but for notice being given or grace
          periods expiring (or both) would be an Event of Default) in the manner
          contemplated by subsection 2.4(d) above.  The Borrower acknowledges
          and agrees that any and all security now or hereafter held by the
          Agent or any Bank for the payment of all or any portion of the
          Obligations shall be held as continuing collateral security for, among
          other things, repayment of the Obligations to the Banks in respect of
          all Bankers' Acceptances.

     (e)  To facilitate the acceptance by each Bank of bills of exchange to be
          Bankers' Acceptances as contemplated by this Agreement, the Borrower
          shall deliver to each Bank, as it may request, a Bankers' Acceptance
          Power of Attorney in the form of Exhibit C attached hereto.

     (f)  Subject to the following subparagraph (g), no prepayment of any
          Bankers' Acceptance shall be made by the Borrower to any Bank prior to
          the maturity date of such Bankers' Acceptance.

     (g)  Upon the occurrence of an Event of Default, notwithstanding the date
          of maturity of any outstanding Bankers' Acceptances, the Borrower
          shall, if the Majority Banks so require,  pay to the Agent forthwith
          upon demand made to the Borrower's Designee, an amount equivalent to
          the amount or amounts required to pay on maturity, the undiscounted
          face amount of all outstanding Bankers' Acceptances which the Banks
          are required to honour and, all such amounts shall be deposited into
          an interest-bearing cash collateral account to be held by the Agent as
          additional security for payment of the undiscounted face amount of
          such outstanding Bankers' Acceptances upon maturity, and accrued
          interest on such cash collateral, at the option of the Agent, may
          either be credited to the Borrower or applied against any Obligations
          which continue to be outstanding.

                                      33
<PAGE>
 
     (h)  If the Agent determines in good faith and notifies the Borrower in
          writing that by reason of circumstances affecting the Canadian money
          market (after having discussed those circumstances with the Borrower)
          there is no market for Bankers' Acceptances, then the right of the
          Borrower to request a Loan in the form of Bankers' Acceptances shall
          be suspended until the Agent, acting reasonably, determines that
          circumstances causing such suspension no longer exist and the Agent so
          notifies the Borrower and until then any Notice of Borrowing with
          respect to any Bankers' Acceptances which is outstanding shall be
          cancelled and the Loan requested therein shall, at the option of the
          Borrower, either not be made or be made as a Canadian Dollar Advance.

3.2       BA Advance Procedures.
          --------------------- 

     (a)  The Agent, promptly following receipt of a Notice of Borrowing
          pursuant to Section 2.3 requesting a BA Advance, shall advise each
          Bank of the aggregate face amount and the term of the Bankers'
          Acceptances to be accepted by it (which terms shall be identical for
          all Banks).  The aggregate face amount of Bankers' Acceptances to be
          accepted by a Bank shall be determined by the Agent by reference to
          the Pro Rata Share of each Bank, except that if the face amount of a
          Bankers' Acceptance would not be a whole multiple of $100,000, the
          face amount shall be increased or reduced by the Agent in its sole and
          unfettered discretion to the nearest whole multiple of $100,000.

     (b)  Each Bank shall purchase such Bankers' Acceptances for an amount equal
          to the BA Proceeds.  Each Bank shall transfer to the Agent, on each
          Borrowing Date, Canadian Dollars in Same Day Funds in an aggregate
          amount equal to the BA Proceeds for the Bankers' Acceptances accepted
          and purchased by such Bank on such date, net of the amount required to
          pay any of its previously accepted Bankers' Acceptances or other Loans
          that are maturing on the applicable Borrowing Date.

     (c)  If the Agent determines that all conditions precedent to an advance
          specified in this Agreement have been met, it shall advance to the
          Borrower the amount delivered by each Bank in the manner contemplated
          in subsection 2.3(c) for other Loans, but if the conditions precedent
          to such advance have not been met by 3:00 p.m. (Toronto time) on a
          Borrowing Date, it shall invest the funds in an overnight investment
          as orally instructed by each Bank until such time as the advance is
          made.

     (d)  If the proposed Depository Bills and Notes Act (Canada) is enacted in
          substantially the terms of Bill C-90 to which first reading was given
          in the House of Commons of Canada on March 13, 1997 (reintroduced as
          Bill S-9) on December 3, 1997) and if at that time or any time
          thereafter the Agent, the Banks and the Borrower determine that any
          Bankers' Acceptances accepted by any Bank under this Agreement after
          the effective date of that Act and after clearing services acceptable
          to the Borrower and the Agent are available shall be "depository
          bills" to which the Act applies then all such Bankers' Acceptances

                                      34
<PAGE>
 
          thereafter shall be issued in the form of a "depository bill" and
          deposited with a "clearing house", as those terms are defined in Bill
          C-90.  At that time the Agent shall, in consultation with the
          Borrower, establish and notify the Borrower of such procedures,
          consistent with the terms of this Agreement and the requirements of
          such Act as are reasonably necessary to accomplish the parties'
          intention.

                                   ----------

                     TAXES, YIELD PROTECTION AND ILLEGALITY
                     --------------------------------------

4.1       Taxes.
          ----- 

     (a)  Any and all payments by each Loan Party to each Bank or the Agent
          under this Agreement and any other Loan Document shall be made free
          and clear of, and without deduction or withholding for, any Taxes.

     (b)  If any Loan Party shall be required by law to deduct or withhold any
          Taxes and Further Taxes from or in respect of any sum payable
          hereunder to any Bank or the Agent, then:

          (i)   the sum payable shall be increased as necessary so that, after
                making all required deductions and withholdings (including
                deductions and withholdings applicable to additional sums
                payable under this Section), such Bank or the Agent, as the case
                may be, receives an amount equal to the sum it would have
                received had no such deductions or withholdings been made;

          (ii)  such Loan Party shall make such deductions and withholdings;

          (iii) such Loan Party shall pay the full amount deducted or withheld
                to the relevant taxing authority or other authority in
                accordance with applicable law; and

          (iv)  such Loan Party shall also pay to each Bank or the Agent for the
                account of such Bank, at the time interest is paid, Further
                Taxes in the amount that the respective Bank specifies as
                necessary to preserve the after-tax yield such Bank would have
                received if such Taxes or Further Taxes had not been imposed.

     (c)  Each Loan Party agrees to indemnify and hold harmless each Bank and
          the Agent for the full amount of (i) Taxes and (ii) Further Taxes in
          the amount that the respective Bank specifies as necessary to preserve
          the after-tax yield such Bank would have received if such Taxes or
          Further Taxes had not been imposed, and any liability (including
          penalties, interest, additions to tax and expenses) arising therefrom
          or with respect thereto, whether or not such Taxes or Further Taxes
          were correctly or legally asserted. Payment under this indemnification
          shall be 

                                      35
<PAGE>
 
          made within 30 days after the date such Bank or the Agent makes
          written demand therefor, provided, however, that such Loan Party shall
          not be obligated to make a payment to the Bank or the Agent (as the
          case may be) pursuant to this Section in respect of penalties,
          interest and other liabilities attributable to any Taxes or Further
          Taxes, if (A) such penalties, interest and other liabilities have
          accrued after such Loan Party has indemnified or paid any additional
          amount pursuant to this Section, or (B) such penalties, interest and
          other liabilities are attributable to the gross negligence or willful
          misconduct of the Bank. After the Bank or the Agent (as the case may
          be) learns of the imposition of Taxes or Further Taxes, such Bank and
          the Agent will act in good faith to promptly notify the relevant Loan
          Party of its obligations hereunder.

     (d)  Within 30 days after the date of any payment by any Loan Party of
          Taxes or Further Taxes, the Borrower's Designee shall furnish to each
          Bank or the Agent the original or a certified copy of a receipt
          evidencing payment thereof, or other evidence of payment satisfactory
          to such Bank or the Agent.

     (e)  If a Bank receives a refund in respect of any Taxes or Further Taxes
          as to which it has been indemnified by any Loan Party pursuant to this
          Section, or with respect to which any Loan Party has paid additional
          amounts pursuant to this Section, it shall within 30 days from the
          date of receipt of such refund pay over the amount of such refund
          (including any interest paid or credited by the relevant taxing
          authority with respect to such refund) to such Loan Party (but only to
          the extent of indemnity payments made, or additional amounts paid, by
          the Loan Party under the Section with respect to the Taxes or Further
          Taxes giving rise to such refund); provided, however, that the Loan
                                             --------  -------               
          Party, upon the request of such Bank agrees to repay the amount paid
          over to the Loan Party to such Bank in the event such Bank is required
          to repay such refund to such relevant authority.

     (f)  For any period with respect to which a Bank ceases to be a resident of
          Canada (except where such Bank has become a non-resident of Canada due
          to a change in treaty, law or regulation occurring subsequent to the
          date of this Agreement), such Bank shall not be entitled to
          indemnification under this Section 4.1 with respect to Taxes imposed
          by any Governmental Authority of Canada (or any political division
          thereof) as a result of such non-residency; provided that if a Bank,
                                                      --------                
          which is otherwise exempt from withholding tax, becomes subject to
          Taxes, the Loan Parties shall take such steps as such Bank shall
          reasonably request, at the Bank's expense, to assist such Bank to
          recover such Taxes (and provided further that if such Bank becomes a
          resident of a jurisdiction other than Canada, this indemnity in favour
          of such Bank for withholding tax gross up shall not exceed 10% of the
          amount of any payment in respect of which a withholding is required).

     (h)  Each Bank and the Agent agrees that it will (i) take all reasonable
          actions reasonably requested by the Loan Parties that are without risk
          or material cost to such Bank or the Agent (as the case may be) to
          maintain all exemptions, available to it from withholding taxes
          (whether available by treaty or existing 

                                      36
<PAGE>
 
          administrative waiver), including the filing of any certificate or
          document if such filing-would avoid the need for or reduce the amount
          of any such additional amounts payable to or for the account of such
          Bank or the Agent (as the case may be) pursuant to this Section 4.1,
          and (ii) to the extent reasonable and without material cost to it,
          otherwise cooperate with the relevant Loan Party to minimize any
          amount payable by such Loan Party under this Section.

4.2       Illegality. If any Bank determines that the introduction of any
          ----------                                                     
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Bank or its applicable Lending Office to make LIBOR
Loans, then, in such event, the affected Bank shall give notice thereof to the
Borrower's Designee (through the Agent). Thereafter, (i) any obligation of that
Bank to make LIBOR Loans (or convert Loans into LIBOR Loans) shall be suspended
until such Bank notifies the Agent and the Borrower's Designee that the
circumstances giving rise to such determination no longer exist, (ii) to the
extent that such determination relates to a LIBOR Loan then being requested by
the Borrower pursuant to a Notice of Borrowing or a Notice of
Conversion/Continuation, such Bank shall make such Loan as (or convert such Loan
to) a U.S. Dollar Loan and (iii) any outstanding LIBOR Loans of such affected
Bank shall convert into U.S. Dollar Loans either on the last day of the Interest
Period thereof, if such Bank may lawfully continue to maintain such LIBOR Loans
to such day, or (subject to Section 4.4) immediately, if such Bank may not
lawfully continue to maintain such LIBOR Loan.

4.3       Increased Costs and Reduction of Return.
          --------------------------------------- 

     (a)  If any Bank determines that, due to either (i) the introduction after
          the date hereof of or any change after the date hereof in or in the
          interpretation of any law or regulation or (ii) the compliance by that
          Bank with any guideline or request from any central bank or other
          Governmental Authority (whether or not having the force of law), there
          shall be any increase in the cost to such Bank of agreeing to make or
          making, funding or maintaining any Loans, then such Bank shall
          promptly give notice to the Borrower's Designee and the Borrower shall
          pay to such Bank, within 15 days of receipt of the notice referred to
          above, such additional amounts (in the form of an increased rate of,
          or a different method of calculating, interest or otherwise as such
          Bank in its sole discretion shall determine) as shall be required to
          compensate such Bank for such increased costs or reductions in amounts
          received or receivable hereunder. To the extent the notice required by
          the preceding sentence and relating to the costs arising under this
          Section 4.3 is given by any Bank more than 90 days after the
          occurrence of the event giving rise to the additional costs of the
          type described in this Section 4.3, such Bank shall not be entitled to
          compensation under this Section 4.3 for any amounts incurred or
          accrued prior to the giving of such notice to the Borrower's Designee.

                                      37
<PAGE>
 
     (b)  If any Bank shall have determined that (i) the introduction after the
          date hereof of any Capital Adequacy Regulation, (ii) any change after
          the date hereof in any Capital Adequacy Regulation, or (iii) any
          change after the date hereof in the interpretation or administration
          of any Capital Adequacy Regulation by any central bank or other
          Governmental Authority charged with the interpretation or
          administration thereof, affects or would affect the amount of capital
          required or expected to be maintained by such Bank or any corporation
          controlling such Bank and (taking into consideration such Bank's or
          such corporation's policies with respect to capital adequacy and such
          Bank's desired return on capital) determines that the amount of such
          capital is increased as a consequence of its Commitment, loans,
          credits or obligations under this Agreement, the Borrower agrees to
          pay such Bank, within 15 days of the receipt of the notice referred to
          below, such additional amounts as shall be required to compensate such
          Bank for the increased cost to such Bank as a result of such increase
          of capital. In determining such additional amounts, each Bank will act
          reasonably and in good faith and will use averaging and attribution
          methods which are reasonable, provided that such Bank's determination
          of compensation under this subsection 4.3(b) shall, absent manifest
          error, be final and conclusive and binding on all parties hereto. Each
          Bank, upon determining that additional amounts will be payable
          pursuant to this subsection 4.3(b), will give prompt written notice
          thereof to the Borrower's Designee, although the failure to give any
          such notice shall not release or diminish the Borrower's obligations
          to pay additional amounts pursuant to this subsection 4.3(b). To the
          extent the notice required by the immediately preceding sentence is
          given by any Bank more than 90 days after the occurrence of the event
          giving rise to the additional costs of the type described in this
          subsection 4.3(b), such Bank shall not be entitled to compensation
          under this subsection 4.3(b) for any amounts incurred or accrued prior
          to the giving of such notice to the Borrower's Designee.

4.4       Funding Losses. The Borrower shall reimburse each Bank and hold each
          --------------                                                      
Bank harmless, within 15 days of written request by such Bank to the Borrower's
Designee (which request shall set forth in reasonable detail the basis for
requesting and the calculation of the amount of such compensation), from any
loss or expense which the Bank may sustain or incur as a consequence of:

     (a)  the failure of the Borrower to make on a timely basis any payment of
          principal of any LIBOR Loan;

     (b)  the failure of the Borrower to borrow, continue or convert a Loan
          after the Borrower's Designee has given (or is deemed to have given) a
          Notice of Borrowing or a Notice of Conversion/Continuation;

     (c)  the failure of the Borrower to make any prepayment in accordance with
          any notice delivered under Sections 2.9 or 2.10;

                                      38
<PAGE>
 
     (d)  the prepayment (including pursuant to Sections 2.9, 2.10 or 4.8) or
          other payment (including after acceleration thereof) of a LIBOR Loan
          on a day that is not the last day of the relevant Interest Period or
          of a BA Advance on a day that is not the maturity date of such
          Bankers' Acceptance; or

     (e)  the conversion under Section 2.4 of any LIBOR Loan to a U.S. Dollar
          Loan or any other type of Loan on a day that is not the last day of
          the relevant Interest Period;

including any such loss or expense arising from the liquidation or re-employment
of funds obtained by it to maintain its LIBOR Loans or BA Advances and from fees
payable to terminate the deposits from which such funds were obtained and from
charges relating thereto (but excluding any loss of anticipated profits).

4.5       Inability to Determine Rates. If the Agent or the Banks shall
          ----------------------------                                 
determine that for any reason adequate and reasonable means do not exist for
determining the Offshore Rate for any requested Interest Period with respect to
a proposed borrowing of LIBOR Loans or conversion or continuation of LIBOR
Loans, or that the Offshore Rate applicable pursuant hereto for any requested
Interest Period with respect to a proposed borrowing of LIBOR Loans, or a
conversion into or continuation of LIBOR Loans does not adequately and fairly
reflect the cost to the Banks of funding such Loans, the Agent will promptly so
notify the Borrower's Designee and each Bank. Thereafter, the obligation of the
Banks to make or maintain LIBOR Loans hereunder shall be suspended until the
Agent upon the instructions of the Banks revokes such notice in writing. Upon
receipt of such notice, the Borrower's Designee may revoke any Notice of
Borrowing or Notice of Conversion/Continuation then submitted by it. In the case
of any LIBOR Loans, if the Borrower's Designee does not revoke such Notice, the
Banks shall make, convert or continue the Loans, as requested by the Borrower's
Designee, in the amount specified in the applicable notice submitted by the
Borrower's Designee, but such Loans shall be made, converted or continued as
U.S. Dollar Loans instead of LIBOR Loans.

4.6       Reserves on LIBOR Loans. The Borrower shall pay to each Bank, as long
          -----------------------                                              
as such Bank shall be required under regulations of the FRB or the Bank of
Canada to maintain reserves with respect to liabilities or assets consisting of
or including LIBOR Loans under any applicable regulations of the central bank or
other relevant Governmental Authority, additional costs on the unpaid principal
amount of each LIBOR Loan equal to the actual costs of such reserves allocated
to such Loan by the Bank (as determined by such Bank in good faith, which
determination shall be conclusive), payable on each date on which interest is
payable on such Loan, provided such Bank shall promptly give notice to the
                      --------                                            
Borrower's Designee and to the Agent of such additional cost. Thereafter the
Borrower shall pay such Bank, within 15 days of receipt of such notice, such
additional amounts (in the form of an increased rate of, or a different method
of calculating, interest or otherwise as such Bank in its sole discretion shall
determine) as shall be required to compensate such Bank for such increased
costs. To the extent the notice required by the preceding sentence and relating
to the costs arising under this Section 4.6 is given by any Bank

                                      39
<PAGE>
 
more than 90 days after the occurrence of the event giving rise to the
additional costs of the type described in this Section 4.6, such Bank shall not
be entitled to compensation under this Section 4.6 for any amounts incurred or
accrued prior to the giving of such notice to the Borrower's Designee.

4.7       Certificates of Banks.  Any Bank claiming reimbursement or
          ---------------------                                     
compensation under this Article IV shall deliver to the Borrower's Designee
(with a copy to the Agent) a certificate setting forth in reasonable detail the
amount payable to the Bank hereunder and such certificate shall be conclusive
and binding on the Loan Parties in the absence of manifest error.

4.8       Substitution of Banks.  Upon the occurrence of any event giving rise
          ---------------------                                               
to the operation of any one of Sections 4.1, 4.2, 4.3 or 4.6 with respect to any
Bank which results in such Bank (an "Affected Bank") charging to the Borrower
                                     -------------                           
increased costs in excess of those generally charged to the Borrower by the
other Banks, or upon notice to the Agent from any Bank that it shall not consent
to a request by the Borrower's Designee for an extension of the Revolving
Termination Date pursuant to subsection 2.12(b), the Borrower's Designee may:
(i) request one or more of the other Banks to acquire and assume all or part of
such Affected Bank's Loans and Commitment; or (ii) designate a replacement
commercial bank, which shall be an Eligible Assignee, satisfactory to the
Borrower's Designee to acquire and assume all or a ratable part of such Affected
Bank's Loans and Commitment (a "Replacement Bank"); provided, however, that the
                                ----------------    --------  -------          
Borrower shall be liable for the payment upon demand of all costs and other
amounts arising under Section 4.4 hereof that result from the acquisition of any
Affected Bank's Loan and/or Commitment (or any portion thereof) by a Bank or
Replacement Bank, as the case may be, on a date other than the last day of the
applicable Interest Period with respect to any LIBOR Loan then outstanding. Any
such designation of a Replacement Bank under clause (ii) shall be effected in
accordance with, and subject to the terms and conditions of, the assignment
provisions contained in Section 11.8 hereof, and shall in any event be subject
to the prior written consent of the Agent (which consents shall not be
unreasonably withheld).

4.9       Change of Lending Office.  Each Bank agrees that on the occurrence of
          ------------------------                                             
any event giving rise to the operation of any one of Sections 4.1, 4.2, 4.3 or
4.6 with respect to such Bank it will, if requested by the Borrower's Designee,
use reasonable efforts (subject to overall policy considerations of such Bank)
to designate another lending office for any Loans affected by such event,
provided that such designation is made on such terms that such Bank and its
--------                                                                   
Lending Office suffer no material economic, legal or regulatory disadvantage,
with the object of avoiding the consequence of the event giving rise to the
operation of such Section.

4.10      Survival.  The agreements and obligations of the Borrower and the
          --------                                                         
other Loan Parties in this Article IV shall survive the termination of the
Commitments and the payment of all other Obligations.

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

routine public disclosure concerning the Borrower or either of the Guarantors),
any Governmental Authority is necessary or required in connection with the
execution, delivery or performance by, or enforcement against, any Loan Party of
the Agreement or any other Loan Document.

6.4       Binding Effect.  This Agreement and each other Loan Document to which
          --------------                                                       
any Loan Party is a party constitute the legal, valid and binding obligations of
such Loan Party, enforceable against such Loan Party in accordance with their
respective terms, except to the extent that the enforceability thereof may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting creditors' rights generally or by equitable
principles relating to enforceability.

6.5       Litigation.  Except as disclosed in JM's Form 10-K with respect to its
          ----------                                                            
fiscal year ended December 31, 1997, there are no actions, suits, proceedings
(regardless of whether enforcement is sought in equity or at law), claims or
disputes pending, or to the best knowledge of JM threatened or contemplated, at

therein provided.

6.6       No Defaults.  No Default or Event of Default exists or would result
          -----------                                                        
from the incurring of any Obligations by any Loan Party.

6.7       ERISA and Canadian Pension Benefits and Employment Benefits
          -----------------------------------------------------------
Compliance.  Except as in each case has not resulted or would not reasonably be
expected to result in a Material Adverse Effect:

     (a)  Each Plan is in compliance in all material respects with the
          applicable provisions of ERISA, the Code and all other U.S. or
          Canadian federal, or state or provincial law. Each Pension Plan which
          is intended to qualify under Section 401(a) of the Code has received a
          favorable determination letter from the IRS and, to the best knowledge
          of JM, nothing has occurred which would cause the loss of such
          qualification. JM and each ERISA Affiliate and the Borrower has made
          all required contributions to any Pension Plan subject to Section 412
          of the Code, and no application for a funding waiver or an extension
          of any amortization period pursuant to Section 412 of the Code has
          been made with respect to any Pension Plan.

     (b)  There are no pending or, to the best knowledge of JM, (or the Borrower
          with respect to its Pension Plans) threatened claims, actions or
          lawsuits, or action by any Governmental Authority, with respect to any
          Plan which has resulted or would reasonably be expected to result in a
          Material Adverse Effect. There has been no prohibited transaction or
          violation of the fiduciary responsibility rules with respect to any
          Plan.

     (c)  (i) No ERISA Event has occurred or is reasonably expected to occur,
          (ii) no Pension Plan has any Unfunded Pension Liability; (iii) neither
          JM nor any ERISA Affiliate nor the Borrower (with respect to itself)
          has incurred, or reasonably expects to incur, any liability under
          Title IV of ERISA with respect to any Pension Plan (other than
          premiums due and not delinquent under Section 4007 of ERISA) or any
          breach or violation of applicable Canadian law (except for any such
          breach or violation of applicable Canadian law that would not
          reasonably be expected to have a Material Adverse Effect) (iv) neither
          JM nor any ERISA Affiliate nor the Borrower (with respect to itself)
          has incurred, or reasonably expects to incur, any liability (and no
          event has occurred which, with the giving of notice under Section 4219
          of ERISA, would result in such liability) under Section 4201 or 4243
          of ERISA with respect to a Multiemployer Plan; and (v) neither JM nor
          any ERISA Affiliate has engaged in a transaction that could be subject
          to Section 4069 or 4212(c) - of ERISA.

6.9       Title to Properties; Liens.  JM and each Material Subsidiary,
          --------------------------                                   
including the Borrower, has good record and marketable title in fee simple to,
or valid leasehold interests in (or the equivalent in the applicable
jurisdiction), all real property necessary or used in the ordinary conduct of
their respective businesses, except for any Permitted Liens and such defects in
or other differences from such required title or interest as would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

6.10      Taxes.  JM and each of its Subsidiaries, including the Borrower,
          -----                                                           
have filed all Federal, provincial, state and other material tax returns and
reports required to be filed, and have paid all Federal, provincial, state and
other material taxes, assessments, fees and other governmental charges levied or
imposed upon them or their properties, income or assets otherwise due and
payable, (i) except those which are being contested in good faith by appropriate
proceedings or (ii) where the failure to so file or pay would not reasonably be
expected to have a Material Adverse Effect.

6.11      Financial Condition.
          ------------------- 

     (a)  The audited consolidated balance sheet of JM and its Subsidiaries
          dated December 31, 1997 and the unaudited balance sheet of the
          Borrower dated December 31, 1997, and each of the related consolidated
          statements of income or operations, stockholders' equity and cash
          flows (other than cash flows for the Borrower, which have not been
          prepared) for the fiscal periods ended on that date: (i) were prepared
          in accordance with GAAP consistently applied throughout the period
          covered thereby, except as otherwise expressly noted therein and
          except for the absence of footnotes in the case of the Borrower's
          financial statements and (ii) are complete and accurate in all
          material respects and fairly present the financial condition of JM and
          its Subsidiaries or the Borrower, as the case may be, as of the date
          thereof and results of operations and (except in the case of the
          Borrower) cash flows for the period covered thereby.

     (b)  Since December 31, 1997, there has been no Material Adverse Effect.

6.12      Environmental Matters.  Except as disclosed in JM's Form 10-K with
          ---------------------                                             
respect to its fiscal year ended December 31, 1997, JM conducts in the ordinary
course of business a review of the effect of existing Environmental Laws and
existing Environmental Claims on the business, operations and properties of JM
and its Subsidiaries, including the Borrower, and as a result thereof JM has
reasonably concluded that such Environmental Laws and Environmental Claims would
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

6.13      Regulated Entities.  None of the Loan Parties or any Subsidiary of
          ------------------                                                
such Loan Parties is an "Investment Company" within the meaning of the
Investment Company Act of 1940. None of the Loan Parties is subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act, any state public utilities code, or any
other U.S. or Canadian, Federal, provincial or state statute or regulation
limiting its ability to incur Indebtedness.

6.14      Copyrights, Patents, Trademarks and Licenses, Etc.  JM and its
          --------------------------------------------------            
Subsidiaries, including the Borrower, own or are licensed or otherwise have the
right to use all of the patents, trademarks, service marks, trade names,
copyrights, contractual franchises, authorizations and other-rights that are
reasonably necessary for the operation of their respective businesses, without
any known conflict with the rights of any other Person, except where the failure
to so own, license or otherwise have the right to use any of the foregoing would
not, alone or in the aggregate, be reasonably expected to have a Material
Adverse Effect. To the best knowledge of JM (i) no product, process, method,
substance, part or other material now employed, or now contemplated to be
employed, by JM or any Subsidiary infringes upon any rights held by any other
Person, (ii) except as specifically disclosed in the JM's Form 10-K for the
fiscal year ended December 31, 1997, no claim or litigation regarding any of the
foregoing is pending or, to the best knowledge of JM, threatened, and (iii) no
patent, invention, device, application, principle or any statute, law, rule,
regulation, standard or code is pending or, to the best knowledge of JM,
proposed, which, in any such case, would reasonably be expected to have a
Material Adverse Effect described in clauses (i), (ii) or (iii).

6.15      Insurance.  The properties of JM and its Material Subsidiaries,
          ---------                                                      
including the Borrower, are insured, with financially sound and reputable
insurance companies or through JM's own program of self-insurance, in such
amounts, with such deductibles and covering such risks as are customary for
companies engaged in similar businesses and owning similar properties in
localities where JM or such Subsidiary operates.

6.16      Full Disclosure.  The factual information (other than any projections
          ---------------                                                      
or pro forma financial information) included in any exhibits, reports,
statements or certificates furnished by or on behalf of JM or any of its
Subsidiaries in connection with the Loan Documents (including the offering and
disclosure materials delivered by or on behalf of each Loan Party to the Banks
prior to the Closing Date) concerning the operations, business, financial
conditions, properties and prospects of JM and its Subsidiaries is, taken as a
whole, true and correct in all material respects as of the date such information
was supplied to the Agent and the Banks and, taken as a whole, does not omit any
material fact required to be stated or necessary to make any statements made, in
light of the circumstances under which they are made, not misleading. All
projections and pro forma financial information are based on good faith
assumptions and estimates that each Loan Party believed reasonable at the time
made. However, because financial projections are based on estimates and
assumptions about circumstances and events that have not yet taken place, actual
results during the period covered by such projections may differ materially from
the projected results.

6.17      Year 2000.  JM has reviewed the areas within its consolidated business
          ---------                                                             
and operations that could be adversely affected by, and has developed or is
developing a plan to address on a timely basis, the "Year 2000 Problem" (that
is, the risk that computer applications used by JM and its Subsidiaries may be
unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999).  Based on such
review and plan, JM reasonably believes that the "Year 2000 Problem" will not
have a Material Adverse Effect.

          Subsidiaries. As to any information contained in materials furnished
          pursuant to subsection 7.2(b), JM shall not be separately required to

other arrangement that would provide the creditors of any Unrestricted

          --------------------------------------                               
(subject to Section 10.9) appoints, designates and authorizes the Agent to take
such action on its behalf under the provisions of this Agreement and each other
Loan Document and to exercise such powers and perform such duties as are
expressly delegated to it by the terms of this Agreement or any other Loan
Document, together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, nor shall the Agent
have or be deemed to have any fiduciary relationship with any Bank, and no
implied covenants, functions, responsibilities duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent. Without limiting the generality of the
foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not intended to connote any fiduciary or other implied (or
express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

          ------------------                                                 
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct),
or (ii) be responsible in any manner to any of the Banks for any recital,
statement, representation or warranty made by any of the Loan Parties, the
Borrower's Designee or any Subsidiary or Affiliate of any of the Loan Parties,
or any officer thereof, contained in this Agreement or in any other Loan
Document, or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection with, this
Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any of the Loan Parties or any other party to
any Loan Document to perform its obligations hereunder or thereunder. No Agent-
Related Person shall be under any obligation to any Bank to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Agreement or any other Loan Document, or to inspect
the properties, books or records of the Loan Parties or any of their respective
Subsidiaries or Affiliates.

10.4      Reliance by Agent.
          ----------------- 

     (a)  The Agent shall be entitled to rely, and shall be fully protected in
          relying, upon any writing, resolution, notice, consent, certificate,
          affidavit, letter, telegram, facsimile, telex or telephone message,
          statement or other document or conversation believed by it to be
          genuine and correct and to have been signed, sent or made by the
          proper Person or Persons, and upon advice and statements of legal
          counsel (including counsel to any of the Loan Parties), independent
          accountants and other experts selected by the Agent. The Agent shall
          be fully justified in failing or refusing to take any action under
          this Agreement or any other Loan Document unless it shall first
          receive such advice or concurrence of the Majority Banks as it deems
          appropriate and, if it so requests, it shall first be indemnified to
          its satisfaction by the Banks against any and all liability and
          expense which may be incurred by it by reason of taking or continuing
          to take any such action. The Agent shall in all cases be fully
          protected in acting, or in refraining from acting, under this
          Agreement or any other Loan Document in accordance with a request or
          consent of the Majority Banks and such request and any action taken or
          failure to act pursuant thereto shall be binding upon all of the
          Banks.

     (b)  For purposes of determining compliance with the conditions specified
          in Section 5.1, each Bank that has executed this Agreement shall be
          deemed to have consented to, approved or accepted or to be satisfied
          with, each document or other matter either sent (or made available) by
          the Agent to such Bank for consent, approval, acceptance or
          satisfaction, or required thereunder to be consented to or approved by
          or acceptable or satisfactory to such Bank.

10.5      Notice of Default.  The Agent shall not be deemed to have knowledge or
          -----------------                                                     
notice of the occurrence of any Default or Event of Default, except with respect
to defaults in the payment of principal, interest and fees required to be paid
to the Agent for the account of the Banks, unless the Agent shall have received
written notice from a Bank, the Borrower's Designee or any other Loan Party
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". The Agent will notify the
Banks of its receipt of any such notice. The Agent shall take such action with
respect to such Default or Event of Default as may be requested by the Majority
Banks in accordance with Article IX; provided, however, that unless and until
                                     --------  -------                       
the Agent has received any such request, the Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Banks.

10.6      Credit Decision.  Each Bank acknowledges that none of the Agent-
          ---------------                                                
Related Persons has made any representation or warranty to it, and that no act
by the Agent hereinafter taken, including any review of the affairs of each Loan
Party and its Subsidiaries, shall be deemed to constitute any representation or
warranty by any Agent-Related Person to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of each
Loan Party and its Subsidiaries, and all applicable bank regulatory laws
relating to the transactions contemplated hereby, and made its own decision to
enter into this Agreement and to extend credit to the Borrower hereunder. Each
Bank also represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Borrower. Unless otherwise
provided in this Agreement, the Agent will, upon receipt of same, forward to all
of the Banks copies of all financial statements, notices, reports and other
documents required to be furnished to the Agent hereunder by any Loan Party
which are not by the terms hereof required to be distributed by such Loan Party
directly to the Banks.  Except for such financial statements, notices, reports
and other documents expressly herein required to be furnished to the Banks by
the Agent, the Agent shall not have any duty or responsibility to provide any
Bank with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of the
Borrower or either Guarantor or any Subsidiary which may come into the
possession of any of the Agent-Related Persons.

10.7      Indemnification of Agent.  Whether or not the transactions
          ------------------------                                  
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrower or the Guarantors and without limiting the obligation of the Borrower
or the Guarantors to do so), in accordance with the Banks' Pro Rata Shares, from
and against any and all Indemnified Liabilities; provided, however, that no Bank
                                                 --------  -------              
shall be liable for the payment to the Agent-Related Persons of any portion of
such Indemnified Liabilities to the extent they are found by a final decision of
a court of competent jurisdiction to have resulted from such Person's gross
negligence or willful misconduct. Without limitation of the foregoing, each Bank
shall reimburse the Agent upon demand for its ratable share of any costs or out-
of-pocket expenses (including Attorney Costs) incurred by the Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Agent is not
reimbursed for such expenses by or on behalf of the Borrower or the Guarantors.
The undertaking in this Section shall survive the termination of the
Commitments, the payment of all other Obligations hereunder and the resignation
or replacement of the Agent.

10.8      Agent in Individual Capacity.  Bank of Montreal and its Affiliates may
          ----------------------------                                          
make loans to, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with each Loan Party and its Subsidiaries and Affiliates as though Bank
of Montreal were not the Agent hereunder and without notice to or consent of the
Banks. The Banks acknowledge that, pursuant to such activities, Bank of Montreal
or its Affiliates may receive information regarding each Loan Party or its
Subsidiaries or Affiliates (including information that may be subject to
confidentiality obligations in favor of such Loan Party or such Subsidiary or
Affiliate) and acknowledge that the Agent shall be under no obligation to
provide such information to them. With respect to its Loans, Bank of Montreal
shall have the same rights and powers under this Agreement as any other Bank and
may exercise the same as though it were not the Agent.

10.9      Successor Agent.  The Agent may, and at the request of the Majority
          ---------------                                                    
Banks shall, resign as Agent upon 30 days' notice to the Banks. If the Agent
resigns under this Agreement, the Majority Banks, after consulting with and
giving due regard to the suggestions of JM, shall appoint from among the Banks a
successor agent for the Banks which successor agent shall be approved by the
Borrower's Designee (such approval not to be unreasonably withheld). If no
successor agent is appointed prior to the effective date of the resignation of
the Agent, the Agent may appoint, after consulting with the Banks and the
Borrower's Designee, a successor agent from among the Banks. Upon the acceptance
of its appointment as successor agent hereunder, such successor agent shall
succeed to all the rights, powers and duties of the retiring Agent and the term
"Agent" shall mean such successor agent and the retiring Agent's appointment,
powers and duties as Agent shall be terminated. After any retiring Agent's
resignation hereunder as Agent, the provisions of this Article X and Sections
11.4 and 11.5 shall enure to its benefit as to any actions taken or omitted to
be taken by it while it was Agent under this Agreement. If no

                                      64
<PAGE>
 
successor agent has accepted appointment as Agent by the date which is 30 days
following a retiring Agent's notice of resignation, the retiring Agent's
resignation shall nevertheless thereupon become effective and the Banks shall
perform all of the duties of the Agent hereunder until such time, if any, as the
Majority Banks appoint a successor agent as provided for above.

therewith as a condition to making any Loan, the same shall be in writing and
signed by the Combined Majority Banks, and any such amendment or waiver so
consented to or consent in writing by such Combined Majority Banks shall be
effective to automatically effect the same amendment, waiver or consent to (but

Banks, as the case may be, affect the rights or duties of the Agent under this
Agreement or any other Loan Document, and (ii) the Fee Letter may be amended, or

11.2      Notices.
          ------- 

     (a)  All notices, requests, consents, approvals, waivers and other
          communications shall be in writing (including, unless the context
          expressly otherwise provides, by facsimile transmission, provided that
          any matter transmitted by the Borrower or the Borrower's Designee by
          facsimile (i) shall be promptly confirmed by a telephone call to the
          recipient at the number specified on Schedule 11.2, and (ii) shall be
          followed promptly by delivery of a hard copy original thereof) and
          mailed, faxed or delivered, to the address or facsimile number
          specified for notices on Schedule 11.2; or, as directed to Borrower's
          Designee or the Agent, to such other address as shall be designated by

          Agent.

     (b)  All such notices, requests and communications shall, when transmitted
          by overnight delivery, or faxed, be effective when delivered for
          overnight (next-day) delivery, or transmitted in legible form by

     (c)  Any agreement of the Agent and the Banks herein to receive certain

          authorized by the Borrower to give such notice and the Agent and the
          Banks shall not have any liability to the Borrower or other Person on
          account of any action taken or not taken by the Agent or the Banks in
          reliance upon such telephonic or facsimile notice. The obligation of

<PAGE>
 
          any failure by the Agent and the Banks to receive written confirmation
          of any telephonic notice or the receipt by the Agent and the Banks of
          a confirmation which is at variance with the terms understood by the
          Agent and the Banks to be contained in the telephonic or facsimile
          notice.

11.3      No Waiver, Cumulative Remedies.  No failure to exercise and no delay
          ------------------------------                                      
in exercising, on the part of the Agent or any Bank, any right, remedy, power or
privilege hereunder, shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, remedy, power or privilege hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy,
power or privilege. The rights provided for in this Agreement and the other Loan
Documents are cumulative and are not exclusive of any other rights, powers,
privileges or remedies provided by law or in equity, or under any other
instrument, document or agreement now existing or hereafter arising.

11.4      Costs and Expenses.  The Borrower shall:

          subsection 5.1(f)) for all reasonable costs and expenses incurred by
          the Agent in connection with (i) the development, preparation,
          delivery and execution of, and any amendment, supplement, waiver or
          modification to (in each case, whether or not consummated), this
          Agreement, any Loan Document and any other documents prepared in
          connection herewith or therewith, and (ii) the consummation of the
          transactions contemplated hereby and thereby; and

     (b)  pay or reimburse the Agent and each Bank within five Business Days
          after demand (subject to subsection 5.1(f)) for all costs and expenses
          (including Attorney Costs) incurred by them in connection with the
          enforcement, attempted enforcement, or preservation of any rights or
          remedies under this Agreement or any other Loan Document during the
          existence of an Event of Default or after acceleration of the Loans
          (including in connection with any "workout" or restructuring regarding
          the Loans, and including in any Insolvency Proceeding or appellate
          proceeding).

11.5      Indemnification.  Whether or not the transactions contemplated hereby

obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including reasonable Attorney Costs) of any
kind or nature whatsoever which may at any time (including at any time following
repayment of the Loans and the termination, resignation or replacement of the
Agent or replacement of any Bank) be imposed on, incurred by or asserted against
any such Person in connection with any investigation, litigation or proceeding
(including any Insolvency Proceeding or appellate proceeding) in any way
relating to or arising out of this Agreement or any document contemplated by or
referred to herein, or the transactions contemplated hereby or the use of the
Proceeds of any Loans, or any 

                                      67
<PAGE>
 
action taken or omitted by any such Person under or in connection with any of
the foregoing, whether or not any Indemnified Person is a party thereto (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that any Loan
Party shall have no obligation hereunder to any Indemnified Person with respect
to Indemnified Liabilities to the extent they are found by a final decision of a
court of competent jurisdiction to have resulted solely from the gross
negligence or willful misconduct of such Indemnified Person. The agreements in
this Section and in Section 11.4 shall survive the termination of the
Commitments and the payment of all other Obligations.

11.6      Payments Set Aside.  To the extent that any Loan Party makes a payment
          ------------------                                                    
to the Agent or the Banks, or the Agent or the Banks exercise their right of
set-off, and such payment or the proceeds of such set-off or any part thereof
are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

11.7   Successors and Assigns.  The provisions of this Agreement shall be
       ----------------------                                            
binding upon and enure to the benefit of the parties hereto and their respective
successors and assigns, except that no Loan Party may assign or transfer any of
its rights or obligations under this Agreement without the prior written consent
of the Agent and each Bank.

     (a)  Any Bank may, with the written consent of the Borrower's Designee and
          the Agent, (which in each case shall not be unreasonably withheld), at

          Borrower's Designee or the Agent shall be required in connection with
          any assignment and delegation by a Bank to an Eligible Assignee that
          is another Bank or an Affiliate of such Bank; and (ii) except in
          connection with an assignment of all of a Bank's rights and
          obligations with respect to its Commitment and Loans any such
          assignment to an Eligible Assignee that is not a Bank hereunder shall
          be equal to or greater than $1,000,000 (Cdn.) or the U.S. Dollar
          Equivalent Amount thereof; and provided further, however, that the

          to the Borrower's Designee and the Agent an Assignment and Acceptance
          Agreement substantially in the form of Exhibit G (an "Assignment and

          Designee with respect to) an executed Assignment and Acceptance and

          the addition of the Assignee and the resulting adjustment of the
          Commitments arising therefrom, and (iii) the assignor Bank shall, to
          the extent that rights and obligations hereunder and under the other
          Loan Documents have been assigned by it pursuant to such Assignment

          assignor Bank shall not relinquish its rights under Article IV or
          under Sections 11.4 and 11.5 to the extent such rights relate to the
          time prior to the effective date of the Assignment and Acceptance. The
          Commitment allocated to each Assignee shall reduce the Commitment of
          the assigning Bank pro tanto.
                             --------- 

     (c)  Within five Business Days after its receipt of notice by the Agent
          that it has received (and, if necessary, consented to) an executed
          Assignment and Acceptance and payment of the processing fee (and
          provided that the Borrower's Designee consents to such assignment in
          accordance with subsection 11.8(a)), the Borrower's Designee shall
          execute and deliver to the Agent any new Notes requested by such
          Assignee evidencing such Assignee's assigned Loans and Commitment and,
          if the assignor Bank has retained a portion of its Loans and its
          Commitment, replacement Notes as requested by the assignor Bank
          evidencing the Loans and Commitment retained by the assignor Bank
          (such Notes to be in exchange for, but not in payment of, the Notes
          held by such Bank, if any).

     (d)  Any Bank may at any time sell to one or more commercial banks or other
          Persons not Affiliates of the Borrower (a "Participant") participating
                                                     -----------                
          interests in any Loans, the Commitment of that Bank and the other
          interests of that Bank (the "originating Bank") hereunder and under
          the other Loan Documents; provided, however, that (i) the originating
                                    --------  -------                          
          Bank's obligations under this Agreement shall remain unchanged, (ii)
          the originating Bank shall remain solely responsible for the
          performance of such obligations, (iii) the Borrower, the Borrower's
          Designee and the Agent shall continue to deal solely and directly with
          the originating Bank in connection with the originating Bank's rights
          and obligations under this Agreement and the other Loan Documents, and
          (iv) no Bank shall transfer or

          grant any participating interest under which the Participant has
          rights to approve any amendment to, or any consent or waiver with
          respect to, this Agreement or any other Loan Document, except to the
          extent such amendment, consent or waiver would require unanimous
          consent of the Banks as described in the first proviso to Section
          11.1. In the case of any such participation, the Participant shall be
          entitled to the benefit of Sections 4.1 (but only if and for so long
          as it is an Eligible Assignee), 4.3 and 11.5 as though it were also a
          Bank hereunder, and if amounts outstanding under this Agreement are
          due and unpaid, or shall have been declared or shall have become due
          and payable upon the occurrence of an Event of Default, each
          Participant shall be deemed to have the right of set-off in respect of
          its participating interest in amounts owing under this Agreement to
          the same extent as if the amount of its participating interest were
          owing directly to it as a Bank under this Agreement.

     (e)  Notwithstanding any other provision in this Agreement, any Bank may at
          any time create a security interest in, or pledge, all or any portion
          of its rights under and interest in this Agreement and any Note held
          by it in favour of any Federal Reserve Bank in accordance with
          Regulation A of the FRB or U.S. Treasury Regulation 31 CFR 203.14,
          and such Federal Reserve Bank may enforce such pledge or security
          interest in any manner permitted under applicable law.

11.9      Confidentiality.  Each Bank agrees to take and to cause its Affiliates
          ---------------                                                       
to take normal and reasonable precautions and exercise due care to maintain the
confidentiality of all information provided to it by any of the Loan Parties or
any Subsidiary, or by the Agent on behalf of such Loan Party or such Subsidiary,
under this Agreement or any other Loan Document, and neither it nor any of its
Affiliates shall use any such information other than in connection with or in
enforcement of this Agreement and the other Loan Documents or in connection with
other business now or hereafter existing or contemplated with any of the Loan
Parties or any Subsidiary; except to the extent such information (i) was or
becomes generally available to the public other than as a result of disclosure
by such Bank, or (ii) was or becomes available on a non-confidential basis from
a source other than any of the Loan Parties or any Subsidiary, provided that
                                                               --------     
such source is not bound by a confidentiality agreement with any of the Loan
Parties or any of their respective Subsidiaries known to such Bank; provided,
                                                                    -------- 
however, that any Bank may disclose such information (A) at the request or
-------

accordance with the provisions of any applicable Requirement of Law; (D) to the

hereunder or under any other Loan Document; (F) to such Bank's independent
auditors, legal counsel and other professional advisors; (G) to any Participant
or Assignee, actual or potential, provided that such Person agrees in writing to

hereunder, (H) as to any Bank or its Affiliate, as expressly permitted under the
terms of any other document or agreement regarding confidentiality to which the
Borrower or any Subsidiary is party or is deemed party with such Bank or such
Affiliate; and (I) to its Affiliates.

11.10     Set-off.  In addition to any rights and remedies of the Banks provided
          -------                                                               
by law, if an Event of Default exists or the Loans have been accelerated, each
Bank is authorized at any time and from time to time, without prior notice to
the Borrower or the Borrower's Designee, any such notice being waived by the
Borrower and the other Loan Parties to the fullest extent permitted by law, to
set off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held by, and other indebtedness at any time
owing by, such Bank to or for the credit or the account of the Borrower against
any and all Obligations owing to such Bank, now or hereafter existing,
irrespective of whether or not the Agent or such Bank shall have made demand
under this Agreement or any Loan Document and although such Obligations may be
contingent or unmatured. Each Bank agrees promptly to notify the Borrower's
Designee and the Agent after any such set-off and application made by such Bank;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application.

11.11     Notification of Addresses, Lending Offices, Etc.  Each Bank shall
          ------------------------------------------------

other administrative information as the Agent shall reasonably request.

          ------------                                                  
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

11.13     Severability.  The illegality or unenforceability of any provision of
          ------------                                                         
this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

11.14     No Third Parties Benefited.  This Agreement is made and entered into
          --------------------------                                          
for the sole protection and legal benefit of the Loan Parties, the Banks, the
Agent and the Agent Related Persons, the Indemnified Persons and their permitted

ANY TYPE BROUGHT BY ANY OF THE PARTIES AGAINST ANY OTHER PARTY OR ANY AGENT-
RELATED PERSON, PARTICIPANT OR ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT

TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE
THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS TO THE EXTENT PERMITTED BY
APPLICABLE LAW WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION,
COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE
THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR
ANY PROVISION HEREOF OR THEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS.

                                                                  ---------
Currency"), be discharged only to the extent that on the Business Day following
--------

such obligation was owing against such loss. If the amount of the Agreement
currency so purchased is greater than the sum originally due to the Agent in
such currency, the Agent agrees to return the amount of any excess to the
applicable Loan Party (or to any other Person who may be entitled thereto under

______________________
*    1. The Leverage Ratio used to compute the Applicable Fee Amount, the
     Applicable Margin with respect to any LIBOR Loans and the applicable BA
     Stamping Fee for any Bankers' Acceptance shall be the Leverage Ratio set
     forth in Schedule 1 attached to the Compliance Certificate most recently
     delivered by the Borrower's Designee pursuant to Section 7.2(a) of the
     Credit Agreement; changes in the Applicable Fee Amount, Applicable Margin
     with respect to the LIBOR Loans and applicable BA Stamping Fee resulting
     from a change in the Leverage Ratio shall become effective upon delivery by
     the Borrower's Designee to the Agent of a new Compliance Certificate
     pursuant to Section 7.2(a). If the Borrower's Designee shall fail to
     deliver a Compliance Certificate within the number of days after the end of
     any fiscal quarter or fiscal year as required pursuant to Section 7.2(a)
     (without giving effect to any grace period), the Applicable Fee Amount,
     Applicable Margin with respect to LIBOR Loans and applicable BA Stamping
     Fee from the first day after the date on which such Compliance Certificate
     was required to be delivered to the Agent to the Day the Borrower's
     Designee delivers to the Agent a Compliance Certificate shall conclusively
     equal the highest Applicable Fee Amount, Applicable Margin with respect to
     LIBOR Loans and applicable BA Stamping Fee set forth above.

     2. Notwithstanding the foregoing, the Applicable Fee Amount, Applicable
     Margin with respect to LIBOR Loans and applicable BA Stamping Fee for every
     day during the six-month period beginning on the Closing Date shall be no
     lower than Level III plus 1/10 of 1% per annum.

     3. If on any day and for each day after the initial six-month period
     referred to in note 2 above the Effective Amount of all Revolving Loans
     plus the Effective Amount of all Swingline Loans plus the Effective Amount
     of all L/C Obligations (as such terms are defined in the U.S. Credit
     Agreement) exceeds 50% of the Aggregate Commitment (as also defined
     therein) then in effect under the U.S. Credit Agreement, (a) the Applicable
     Margin with respect to LIBOR Loans shall be increased by 1/10 of 1% per
     annum for each such day and (b) a supplemental BA Stamping Fee shall be
     payable for each such day in respect of each Bankers' Acceptance
     outstanding on each such day, payable on the date such Bankers' Acceptance
     matures, in an amount determined by (i) multiplying the undiscounted face
     amount of such Bankers' Acceptance by 1/10 of 1% and (ii) dividing the
     result by 365 or 366, as the case may be.
