Letter of Credit Liabilities exceed $45,000,000 and (iii) the expiration date of
any Letter of Credit extend beyond the earlier of the Commitment Termination
Date and the date one year following the issuance of such Letter of Credit
(provided that any Letter of Credit with a one-year tenor may provide for the
renewal thereof for additional one-year periods, which periods shall in any
event not extend beyond the Commitment Termination Date). On the Effective Date,
all Existing Letters of Credit shall automatically, without any action on the
part of any Person, be deemed to be Letters of Credit issued and outstanding
hereunder (with the Existing Letters of Credit denominated in Dollars being
deemed to be issued under the US$ Commitments and the Existing Letters of Credit
denominated in other currencies being deemed to be issued under the
Multi-Currency Commitments).

                  The following additional provisions shall apply to Letters of
         Credit:

                  (a Each Borrower shall give the Administrative Agent (or if
         the Letter of Credit is to be issued under the Multi-Currency
         Commitments, the Multi-Currency Payment Agent) at least three Business
         Days' irrevocable prior notice (effective upon receipt) specifying the
         Business Day (which shall be no later than 5 days preceding the
         Commitment Termination Date) on which each Letter of Credit is to be
         issued and the account party or parties therefor and describing in
         reasonable detail the proposed terms of such Letter of Credit
         (including the beneficiary thereof) and the nature of the transactions
         or obligations proposed to be supported thereby. Any Letter of Credit
         to be issued in a currency other than Dollars shall be issued under the
         Multi-Currency Commitments. Upon receipt of any such notice, the
         Administrative Agent or the Multi-Currency Payment Agent, as the case
         may be, shall advise the Issuing Bank of the contents thereof.

                  (b On each day during the period commencing with the issuance
         by the Issuing Bank of any Letter of Credit and until such Letter of
         Credit shall have expired or been terminated, the US$ Commitment or
         Multi-Currency Commitment of each Lender shall be deemed to be utilized
         for all purposes of this Agreement in an amount equal to such Lender's
         US$ Commitment Percentage or Multi-Currency Commitment Percentage, as
         the case may be, of the then undrawn stated amount of such Letter of
         Credit. Each Lender (other than the Issuing Bank) agrees that, upon the
         issuance of any Letter of Credit

<PAGE>
                                                                              35

         hereunder, it shall automatically acquire a participation in the
         Issuing Bank's rights and obligations under such Letter of Credit in an
         amount equal to such Lender's US$ Commitment Percentage or
         Multi-Currency Commitment Percentage, as the case may be, of such
         rights and obligations, and each Lender (other than the Issuing Bank)
         thereby shall automatically absolutely, unconditionally and irrevocably
         assume, as primary obligor and not as surety, and be unconditionally
         obligated to the Issuing Bank to pay and discharge when due, its US$
         Commitment Percentage or Multi-Currency Commitment Percentage of the
         Issuing Bank's obligation to pay drawings under such Letter of Credit.

                  (c Upon receipt from the beneficiary of any Letter of Credit
         of any demand for payment under such Letter of Credit, the Issuing Bank
         shall promptly notify the relevant Borrower (through the Administrative
         Agent or the Multi-Currency Payment Agent, as the case may be) of the
         amount to be paid by the Issuing Bank as a result of such demand and
         the date on which payment is to be made by the Issuing Bank to such
         beneficiary in respect of such demand. Notwithstanding the identity of
         the account party of any Letter of Credit, the relevant Borrower hereby
         unconditionally agrees to pay and reimburse the Administrative Agent or
         the Multi-Currency Payment Agent, as the case may be, for account of
         the Issuing Bank for the amount of each demand for payment under such
         Letter of Credit that is in substantial compliance with the provisions
         of such Letter of Credit at or prior to the date on which payment is to
         be made by the Issuing Bank to the beneficiary thereunder, without
         presentment, demand, protest or other formalities of any kind.

                  (d Forthwith upon its receipt of a notice referred to in
         paragraph (c) of this Section 2.08, the relevant Borrower shall advise
         the Administrative Agent or the Multi-Currency Payment Agent, as the
         case may be, whether or not such Borrower intends to borrow hereunder
         to finance its obligation to reimburse the Issuing Bank for the amount
         of the related demand for payment and, if it does, submit a notice of
         such borrowing as provided in Section 5.05 hereof.

                  (e Each Lender (other than the Issuing Bank) shall pay to the
         Administrative Agent or the Multi-Currency Payment Agent, as the case
         may be, for account of the Issuing Bank at an account in New York, New
         York specified by the Administrative Agent (or the Multi-Currency
         Payment Agent, as the case may be) in Dollars and in immediately
         available funds the amount of such Lender's US$ Commitment Percentage
         or Multi-Currency Commitment Percentage, as the case may be, of any
         payment under a Letter of Credit issued under the US$ Commitments or
         the Multi-Currency Commitments, as the case may be, upon notice by the
         Issuing Bank (through the Administrative Agent) to such Lender
         requesting such payment and specifying such amount. Each such Lender's
         obligation to make such payment to the Administrative Agent or the
         Multi-Currency Payment Agent, as the case may be, for account of the
         Issuing Bank under this paragraph (e), and the Issuing Bank's right to
         receive the same, shall be absolute and unconditional and shall not be
         affected by any circumstance whatsoever (other than gross negligence or
         wilful misconduct of the Issuing Bank), including, without limitation,
         the failure of any other Lender to make its payment under this
         paragraph (e), the financial condition of the Company or the Borrowers
         (or any other

         account party), any failure to satisfy any condition precedent to any
         Loan, the existence of any Default or the termination of the
         Commitments. Each such payment to the Issuing Bank shall be made
         without any offset, abatement, withholding or reduction whatsoever. If
         any Lender shall default in its obligation to make any such payment to
         the Administrative Agent or the Multi-Currency Payment Agent, as the
         case may be, for account of the Issuing Bank, for so long as such
         default shall continue the Administrative Agent or the Multi-Currency
         Payment Agent, as the case may be, may at the request of the Issuing
         Bank withhold from any payments received by the Administrative Agent or
         the Multi-Currency Payment Agent, as the case may be, under this
         Agreement or any Note for account of such Lender the amount so in
         default and, to the extent so withheld, pay the same to the Issuing
         Bank in satisfaction of such defaulted obligation.

                  (f Upon the making of each payment by a Lender to the Issuing
         Bank pursuant to paragraph (e) above in respect of any Letter of
         Credit, such Lender shall, automatically and without any further action
         on the part of the Administrative Agent (or the Multi-Currency Payment
         Agent, as the case may be), the Issuing Bank or such Lender, acquire
         (i) a participation in an amount equal to such payment in the
         Reimbursement Obligation owing to the Issuing Bank hereunder and under
         the Letter of Credit Documents relating to such Letter of Credit and
         (ii) a participation in a percentage equal to such Lender's US$
         Commitment Percentage or Multi-Currency Percentage, as the case may be,
         in any interest or other amounts payable by the relevant Borrower
         hereunder and under such Letter of Credit Documents in respect of such
         Reimbursement Obligation (other than the commissions, charges, costs
         and expenses payable to the Issuing Bank pursuant to paragraph (g) of
         this Section 2.08). Upon receipt by the Issuing Bank from or for
         account of the relevant Borrower of any payment in respect of any
         Reimbursement Obligation or any such interest or other amount
         (including by way of setoff or application of proceeds of any
         collateral security) the Issuing Bank shall promptly pay to the
         Administrative Agent (or the Multi-Currency Payment Agent, as the case
         may be) for account of each Lender entitled thereto such Lender's US$
         Commitment Percentage or Multi-Currency Percentage, as the case may be,
         of such payment, each such payment by the Issuing Bank to be made in
         the same money and funds in which received by the Issuing Bank. In the
         event any payment received by the Issuing Bank and so paid to the
         Lenders hereunder is rescinded or must otherwise be returned by the
         Issuing Bank, each Lender shall, upon the request of the Issuing Bank
         (through the Administrative Agent or the Multi-Currency Payment Agent,
         as the case may be), repay to the Issuing Bank (through the
         Administrative Agent or the Multi-Currency Payment Agent, as the case
         may be) the amount of such payment paid to such Lender, with interest
         at the rate specified in paragraph (j) of this Section 2.08.

                  (g The Company shall pay to the Administrative Agent or the
         Multi-Currency Payment Agent, as the case may be, for account of the
         Lenders (ratably in accordance with their respective US$ Commitment
         Percentages or Multi-Currency Percentages, as the case may be) a letter
         of credit fee in Dollars in respect of each Letter of Credit in an
         amount equal to the Applicable L/C Percentage of the daily average
         undrawn stated amount of such Letter of Credit for the period from and

         of a Letter of Credit that is drawn in full or is otherwise terminated
         other than on the stated expiration date of such Letter of Credit, to
         but excluding the date such Letter of Credit is drawn in full or is
         terminated (such fee to be non-refundable, to be paid in arrears on
         each Quarterly Date and on the Commitment Termination Date and on the
         date of expiry or termination or full utilization of such Letter of
         Credit and to be calculated for any day after giving effect to any
         payments made under such Letter of Credit on such day). In addition,
         the Company shall pay to the Administrative Agent or the Multi-Currency
         Payment Agent, as the case may be, for account of the Issuing Bank a
         fronting fee in Dollars in respect of each Letter of Credit in an
         amount equal to 0.25% per annum of the daily average undrawn stated
         amount of such Letter of Credit for the period from and including the
         date of issuance of such Letter of Credit (i) in the case of a Letter
         of Credit that expires in accordance with its terms, to and including
         such expiration date and (ii) in the case of a Letter of Credit that is
         drawn in full or is otherwise terminated other than on the stated
         expiration date of such Letter of Credit, to but excluding the date
         such Letter of Credit is drawn in full or is terminated (such fee to be
         non-refundable, to be paid in arrears on each Quarterly Date and on the
         Commitment Termination Date and to be calculated for any day after
         giving effect to any payments made under such Letter of Credit on such
         day) plus all commissions, charges, costs and expenses in the amounts
         customarily charged by the Issuing Bank from time to time in like
         circumstances with respect to the issuance of each Letter of Credit and
         drawings and other transactions relating thereto.

                  (h Promptly following the end of each calendar month, the
         Issuing Bank shall deliver (through the Administrative Agent or the
         Multi-Currency Payment Agent, as the case may be) to each Lender and
         each Borrower a notice describing the aggregate amount of all Letters
         of Credit outstanding at the end of such month. Upon the request of any
         Lender from time to time, the Issuing Bank shall deliver any other
         information reasonably requested by such Lender with respect to each
         Letter of Credit then outstanding.

                  (i The issuance by the Issuing Bank of each Letter of Credit
         shall, in addition to the conditions precedent set forth in Section 7
         hereof, be subject to the conditions precedent that (i) such Letter of
         Credit shall be in such form, contain such terms and support such
         transactions as shall be satisfactory to the Issuing Bank consistent
         with its then current practices and procedures with respect to letters
         of credit of the same type, (ii) such Letter of Credit shall be
         denominated in Dollars or a Multi-Currency and (iii) the relevant
         Borrower shall have executed and delivered such applications,
         agreements and other instruments relating to such Letter of Credit as
         the Issuing Bank shall have reasonably requested consistent with its
         then current practices and procedures with respect to letters of credit
         of the same type, provided that in the event of any conflict between
         any such application, agreement or other instrument and the provisions
         of this Agreement or any Security Document, the provisions of this
         Agreement and the Security Documents shall control.

                  (j To the extent that any Lender shall fail to pay any amount
         required to be paid pursuant to paragraph (e) or (f) of this Section
         2.08 on the due date therefor, such Lender

         Agent or the Multi-Currency Payment Agent, as the case may be) on such
         amount from and including such due date to but excluding the date such
         payment is made at a rate per annum equal to the Federal Funds
         Effective Rate or, in the case of any amount payable in a currency
         other than Dollars, the rate determined by the Administrative Agent or
         the Multi-Currency Payment Agent (in the case of Letters of Credit
         issued under the Multi-Currency Commitments) in its discretion as the
         appropriate rate for interbank settlements, PROVIDED that if such
         Lender shall fail to make such payment to the Issuing Bank within three
         Business Days of such due date, then, retroactively to the due date,
         such Lender shall be obligated to pay interest on such amount at the
         rate then payable by the relevant Borrower on such amount.

                  (k The issuance by the Issuing Bank of any modification or
         supplement to any Letter of Credit hereunder shall be subject to the
         same conditions as are applicable under this Section 2.08 to the
         issuance of new Letters of Credit, and no such modification or
         supplement shall be issued hereunder unless either (i) the respective
         Letter of Credit affected thereby would have complied with such
         conditions had it originally been issued hereunder in such modified or
         supplemented form or (ii) each Lender shall have consented thereto.

The Company hereby indemnifies and holds harmless each Lender (including the
Issuing Bank, the Administrative Agent and the Multi-Currency Payment Agent from
and against any and all claims and damages, losses, liabilities, costs or
expenses that such Lender, the Administrative Agent or the Multi-Currency
Payment Agent may incur (or that may be claimed against such Lender, the
Administrative Agent or the Multi-Currency Payment Agent by any Person
whatsoever) by reason of or in connection with the execution and delivery or
transfer of or payment or refusal to pay by the Issuing Bank under any Letter of
Credit; PROVIDED that the Company shall not be required to indemnify any Lender,
the Administrative Agent or the Multi-Currency Payment Agent for any claims,
damages, losses, liabilities, costs or expenses to the extent, but only to the
extent, caused by (x) the willful misconduct or gross negligence of the Issuing
Bank in determining whether a request presented under any Letter of Credit
complied with the terms of such Letter of Credit or (y) in the case of the
Issuing Bank, its failure to pay under any Letter of Credit after the
presentation to it of a request strictly complying with the terms and conditions
of such Letter of Credit. Nothing in this Section 2.08 is intended to limit the
other obligations of any Borrower, any Lender, the Administrative Agent or the
Multi-Currency Payment Agent under this Agreement.

                  2.9 CURRENCY FLUCTUATIONS, ETC. (a) Not later than 1:00 p.m.,
New York City time, on each Calculation Date, the Multi-Currency Payment Agent
shall (i) determine the Exchange Rate as of such Calculation Date with respect
to each Multi-Currency for which there are at such time outstanding
Multi-Currency Loans or Letters of Credit issued under the Multi-Currency
Commitments and (ii) give notice thereof to the Multi-Currency Lenders which
have committed to make Multi-Currency Loans in each such Multi-Currency and to
the Company. The Exchange Rates so determined shall become effective on the
first Business Day immediately following the relevant Calculation Date (a "RESET
DATE") and shall remain effective until the next succeeding Reset Date.

                  (b Not later than 5:00 p.m., New York City time, on each Reset
Date, the Multi-Currency Payment Agent shall (i) determine the Dollar Equivalent
of the Multi-Currency Loans or Letter of Credit Liabilities under the
Multi-Currency Commitments in each Multi-Currency then outstanding (after giving
effect to any Multi-Currency Loans to be made or repaid on such date) and (ii)
notify the Multi-Currency Lenders and the Company of the results of such
determination.

                  (c If on any Reset Date, the Dollar Equivalent of the
aggregate principal amount of Multi-Currency Loans and Letters of Credit issued
under the Multi-Currency Commitments outstanding exceeds 105% of the aggregate
principal amount of the Multi-Currency Commitments, then the Company shall,
within three Business Days after notice thereof from the Multi-Currency Payment
Agent, prepay (in any Multi-Currency as selected by the Company) Multi-Currency
Loans in an aggregate amount such that, after giving effect thereto, the Dollar
Equivalent of all such Multi-Currency Loans, together with Letters of Credit
issued under the Multi-Currency Commitments, shall be equal to or less than such
aggregate amount of Multi-Currency Commitments (and in the event that after such
prepayment, the Dollar Equivalent of the outstanding stated amount of the
Letters of Credit issued under the Multi-Currency Commitments is more than such
aggregate amount of the Multi-Currency Commitments, the Company shall provide
cash cover for the difference by paying to the Multi-Currency Payment Agent
immediately available funds in an amount equal to such difference, which funds
shall be retained by the Multi-Currency Payment Agent in the Collateral Account
as such collateral security for such Letter of Credit Liabilities). If any such
prepayment occurs on a day which is not the last day of the then current
Interest Period with respect thereto, the Company shall pay to the
Multi-Currency Lenders such amounts, if any, as may be required pursuant to
Section 6.05.

                  3.2  PREPAYMENTS AND CONVERSIONS.

                  (a OPTIONAL PREPAYMENTS AND CONVERSIONS. Each Borrower shall
have the right to prepay Loans and to convert Loans in Dollars of one Type into
Loans of the other Type, at any time or from time to time, provided, that the
relevant Borrower shall give the Administrative Agent or the Multi-Currency

subsequent to the Effective Date of Indebtedness other than Indebtedness
incurred pursuant to Section 9.08 hereof (except Section 9.08(vii)) (it being
understood that this Section 3.02(b) shall not constitute a waiver of any
provision of Section 9.08), then the Borrowers shall prepay the Loans (and/or
provide cover for Letter of Credit Liabilities as specified in paragraph (d)

any date, the Company or any Subsidiary of the Company shall receive Net Cash
Proceeds from any disposition of assets or any Recovery Event, then, unless such
disposition of assets or Recovery Event shall be a Reinvestment Event, the
Revolving Commitments shall be reduced or the Term Loans prepaid, as the case
may be, by an amount equal to such Net Cash Proceeds to the extent such Net Cash
Proceeds, together with all other such Net Cash Proceeds from dispositions of
assets or Recovery Events that are not Reinvestment Events, exceeds $15,000,000

the case may be.

                  (ii) Amounts to be applied in connection with prepayments and
Revolving Commitment reductions made pursuant to this Section 3.02(c) shall be
applied, FIRST, to the prepayment of the Term Loans (which may not be
reborrowed) and, SECOND, to reduce permanently the Revolving Commitments. Each
prepayment of the Loans under this Section 3.02(c) shall be accompanied by
accrued interest to the date of such prepayment on the amount prepaid. To the
extent that, after giving effect to any such reduction of the Revolving
Commitments, the aggregate principal amount of the US$ Loans or the
Multi-Currency Loans and the aggregate amount of Letter of Credit Liabilities
under the US$ Commitments or the Multi-Currency Commitments, as the case may be,
would exceed such Commitments, the Borrowers shall, first, prepay Loans
thereunder and, second, provide cover for Letter of Credit Liabilities
thereunder as specified in paragraph (d) below, in an aggregate amount equal to
such excess. The Company shall notify the Administrative Agent promptly upon the
occurrence of any event giving rise to a prepayment or Commitment reduction
under this Section 3.02(c).

                  (d) COVER FOR LETTER OF CREDIT LIABILITIES. In the event that
the US$ Loans or the Multi-Currency Loans have been repaid in full, amounts
payable under Section 3.02(b) or 3.02(c) shall be applied to provide cash cover
for outstanding Letters of Credit under the US$ Commitments or the
Multi-Currency Commitments, as the case may be, in which event the Company shall
effect the same by paying to the Administrative Agent or the Multi-Currency
Payment Agent, as the case may be, immediately available funds in an amount
equal to the required amount, which funds shall be retained by the
Administrative Agent or the Multi-Currency Payment Agent in the Collateral
Account as collateral security for such Letter of Credit Liabilities until such
time as the Letters of Credit under such Commitments shall have been terminated
and all of the Letter of Credit Liabilities paid in full.

                  Section 4.  PAYMENTS OF PRINCIPAL AND INTEREST.

                  4.1 REPAYMENT OF LOANS. (a) The Borrowers hereby promise to
pay to the Administrative Agent or the Multi-Currency Payment Agent, as the case
may be, for the account of each Revolving Lender the entire outstanding
principal amount of such Lender's Revolving Loans, and each Revolving Loan shall
mature, on the Commitment Termination Date.

                  (b) (i) The aggregate principal amount of the Tranche A Term

                  4.02 INTEREST. Each Borrower will pay to the Administrative
Agent or, in the case of Multi-Currency Loans, to the Multi-Currency Payment
Agent, for the account of each Lender interest on the unpaid principal amount of
each Loan made by such Lender to such Borrower for the period commencing on the
date of such Loan to but excluding the date such Loan shall be paid in full, at
the following rates per annum:

                  (a if such Loan is an ABR Loan, the Alternate Base Rate PLUS
         the Applicable Margin; and

                  (b if such Loan is a Eurocurrency Loan, the Eurocurrency Rate
         PLUS the Applicable Margin.

                  Notwithstanding the foregoing, each Borrower hereby promises
to pay to the Administrative Agent or, in the case of Multi-Currency Loans, to
the Multi-Currency Payment Agent, for account of each Lender interest at the
applicable Post-Default Rate (x) on any

<PAGE>
                                                                              43

principal of any Loan made by such Lender to such Borrower, on any Reimbursement
Obligation held by such Lender and on any other amount payable by such Borrower
hereunder or under the Note held by such Lender to or for account of such Lender
(but, if such amount is interest, only to the extent legally enforceable), that
shall not be paid in full when due (whether at stated maturity, by acceleration,
by mandatory prepayment or otherwise), for the period from and including the due
date thereof to but excluding the date the same is paid in full and (y) during
any period when an Event of Default shall have occurred under Section 10.01(a)
hereof and for so long as such Event of Default shall be continuing, on any
principal of any Loan made by such Lender to such Borrower.

                  Accrued interest on each Loan shall be payable (i) if such
Loan is an ABR Loan, on each Quarterly Date, (ii) if such Loan is a Eurocurrency
Loan, on the last day of each Interest Period for such Loan (and, if such
Interest Period exceeds three months' duration, quarterly, commencing on the
first quarterly anniversary of the first day of such Interest Period), and (iii)
in any event, upon the payment, prepayment or conversion thereof, but only on
the principal so paid or prepaid or converted; PROVIDED that interest payable at
the Post-Default Rate shall be payable from time to time on demand of the
Administrative Agent (or the Multi-Currency Payment Agent, in the case of
Multi-Currency Loans) or the Majority Lenders. Promptly after the determination
of any interest rate provided for herein or any change therein, the
Administrative Agent shall notify the Lenders and each Borrower thereof.

                  Notwithstanding the foregoing provisions of this Section 4.02,
if at any time the rate of interest set forth above on any Loan of any Lender
(the "Stated Rate" for such Loan) exceeds the maximum non-usurious interest rate
permissible for such Lender to charge commercial borrowers under applicable law
(the "Maximum Rate" for such Lender), the rate of interest charged on such Loan
of such Lender hereunder shall be limited to the Maximum Rate for such Lender.

                  In the event the Stated Rate for any Loan of a Lender that has
theretofore been subject to the preceding paragraph at any time is less than the
Maximum Rate for such Lender, the principal amount of such Loan shall bear
interest at the Maximum Rate for such Lender until the total amount of interest
paid to such Lender or accrued on its Loans hereunder equals the amount of
interest which would have been paid to such Lender or accrued on such Lender's
Loans hereunder if the Stated Rate had at all times been in effect.

                   In the event, upon payment in full of all amounts payable
hereunder, the total amount of interest paid to any Lender or accrued on such
Lender's Loans under the terms of this Agreement is less than the total amount
of interest which would have been paid to such Lender or accrued on such
Lender's Loans if the Stated Rate had, at all times, been in effect, then the
relevant Borrower shall, to the extent permitted by applicable law, pay to the
Administrative Agent or, in the case of Multi-Currency Loans, to the
Multi-Currency Payment Agent, for the account of such Lender an amount equal to
the difference between (a) the lesser of (i) the amount of interest which would
have accrued on such Lender's Loans if the Maximum Rate for such Lender had at
all times been in effect or (ii) the amount of interest which would have accrued
on such Lender's Loans if the Stated Rate had at all times been in effect and
(b) the amount of interest actually paid to such Lender or accrued on its Loans
under this Agreement. In the event

any Lender ever receives, collects or applies as interest any sum in excess of
the Maximum Rate for such Lender, such excess amount shall be applied to the
reduction of the principal balance of its Loans or to other amounts (other than
interest) payable hereunder, and if no such principal is then outstanding, such
excess or part thereof remaining shall be paid to such Borrower.

                  Section 5.  PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

                  5.1 PAYMENTS. (a) Except to the extent otherwise provided
herein, all payments of principal, interest, Reimbursement Obligations and other
amounts to be made by any Borrower under the US$ Commitments, the US$-Canadian
Commitments, the Multi-Currency Commitments, the Tranche A Term Commitments or
the Tranche B Term Commitments and under the corresponding Notes shall (except
in the case of payments of principal and interest on Multi-Currency Loans or
Letter of Credit Liabilities incurred under the Multi-Currency Commitments) be
made in Dollars, in immediately available funds, to the Administrative Agent at
an account in New York, New York specified by the Administrative Agent, not
later than 11:00 a.m. New York time on the date on which such payment shall
become due (each such payment made after such time on such due date to be deemed
to have been made on the next succeeding Business Day). The Administrative
Agent, or any Lender for whose account any such payment is made, may (but shall
not be obligated to) debit the amount of any such payment which is not made by
such time to any ordinary deposit account of such Borrower with the
Administrative Agent or such Lender, as the case may be. The relevant Borrower
shall, at the time of making each such payment, specify to the Administrative
Agent the Loans or other amounts payable by such Borrower hereunder to which
such payment is to be applied (and in the event that it fails to so specify, or
if an Event of Default has occurred and is continuing, the Administrative Agent
may apply such payment for the benefit of the Lenders as it may elect in its
sole discretion, but subject to the other terms and conditions of this
Agreement, including without limitation, Section 5.02 hereof). Each payment
received by the Administrative Agent under the US$ Commitments, the US$-Canadian
Commitments, the Multi-Currency Commitments, the Tranche A Term Commitments or
the Tranche B Term Commitments or under any corresponding Note (except in the
case of payment of principal and interest on Multi-Currency Loans or Letter of
Credit Liabilities incurred under the Multi-Currency Commitments) for the
account of a Lender shall be paid promptly to such Lender, in immediately
available funds, for the account of such Lender's Applicable Lending Office. If
the due date of any such payment would otherwise fall on a day which is not a
Business Day such date shall be extended to the next succeeding Business Day and
interest shall be payable for any principal so extended for the period of such
extension.

                  (b) Except to the extent otherwise provided herein, all
payments of principal and interest on Multi-Currency Loans and Letter of Credit
Liabilities incurred under the Multi-Currency Commitments and under
corresponding Notes to be made by any Borrower shall be made in such currency,
in immediately available funds, to the Multi-Currency Payment Agent at an
account in London specified by the Multi-Currency Payment Agent, not later than
11:00 a.m. London time on the date on which such payment shall become due (each
such payment made after such time on such due date to be deemed to have been
made on the next succeeding Business Day). The Multi-Currency Payment Agent, or
any Lender for whose account any such payment is made, may (but shall not be
obligated to) debit the amount of any such payment

<PAGE>
                                                                              45

which is not made by such time to any ordinary deposit account of such Borrower
with the Multi-Currency Payment Agent or such Lender, as the case may be. The
relevant Borrower shall, at the time of making each such payment, specify to the
Multi-Currency Payment Agent the Loans or other amounts payable by such Borrower
hereunder to which such payment is to be applied (and in the event that it fails
to so specify, or if an Event of Default has occurred and is continuing, the
Multi-Currency Payment Agent may apply such payment for the benefit of the
Lenders as it may elect in its sole discretion, but subject to the other terms
and conditions of this Agreement, including without limitation, Section 5.02
hereof). Each such payment received by the Multi-Currency Payment Agent for the
account of a Lender shall be paid promptly to such Lender, in immediately
available funds, for the account of such Lender's Applicable Lending Office. If
the due date of any such payment would otherwise fall on a day which is not a
Business Day such date shall be extended to the next succeeding Business Day and
interest shall be payable for any principal so extended for the period of such
extension.

                  (c) All payments made by each Borrower hereunder and under the
Notes shall be made without set-off or counterclaim.

                  5.2 PRO RATA TREATMENT. (a) With respect to the US$ Lenders,
except to the extent otherwise provided herein: (i) each borrowing from the US$

Loans and the Tranche B Term Loans, PRO RATA according to the then outstanding

or in Section 3.02 hereof , with respect to the amount of any prepayment
described in Section 3.02 hereof that is allocated to Tranche B Term Loans, at
any time when Tranche A Term Loans remain outstanding, the Company will, in lieu
of applying such amount to the prepayment of Tranche B Term Loans, as provided
in Section 3.02 hereof, on or prior to the date specified in Section 5.05 for
such prepayment, give the Administrative Agent telephonic notice (promptly
confirmed in writing) requesting that the Administrative Agent notify, as
promptly as practicable, each Tranche B Term Lender of the offer by the Borrower
to prepay the relevant Term Loans of such Lender by an amount equal to the
portion of the prepayment applicable to such Lender's Tranche B Term Loans.
Within four Business Days after such notification by the Administrative Agent,
each such Tranche B Term Lender shall give the Administrative Agent and the
Company notice in writing indicating its full or partial acceptance or rejection
of such offer by the Company and in the case of a partial acceptance, the amount
of such portion of the prepayment for which such Tranche B Term Lender accepts

being agreed that any Tranche B Term Lender not responding to such notification
from the Administrative Agent within such four Business Days shall be deemed to
have accepted in full such offer), the Company shall pay, as promptly as
practicable on or after the date so specified for such prepayment, (i) to the
relevant Tranche B Term Lenders the aggregate amount necessary to prepay that
portion of the outstanding relevant Term Loans in respect of which such Lenders
have accepted prepayment as described above, and (ii) to the Tranche A Term
Lenders an amount equal to the portion of the prepayment allocated to Tranche B
Term Loans that is not accepted by the relevant Lenders, and such amount shall
be applied to the prepayment of the Tranche A Term Loans.

                  5.3 COMPUTATIONS. Interest and fees shall be computed on the
basis of a year of 360 days (or 365 or 366 days, as the case may be, in the case
of (a) ABR Loans the interest rate payable on which is then based on the Prime
Rate and (b) Multi-Currency Loans denominated in Pounds Sterling) and actual
days elapsed (including the first day but excluding the last day) occurring in
the period for which payable.

                  5.4  MINIMUM AND MAXIMUM AMOUNTS; TYPES.

                  (a) US$ LOANS; US$-CANADIAN LOANS; DOLLAR-DENOMINATED
MULTI-CURRENCY LOANS; TRANCHE A TERM LOANS; AND TRANCHE B TERM LOANS. Except for
prepayments made pursuant to Section 3.02(b) hereof, each borrowing, conversion
and prepayment of principal of US$ Loans, US$-Canadian Loans, Dollar-denominated
Multi-Currency Loans, Tranche A Term Loans and Tranche B Term Loans shall be in
an aggregate principal amount equal to (a) in the case of Eurocurrency Loans,
$1,000,000 or a larger multiple of $100,000, and (b) in the case of ABR Loans,
$500,000 or a larger multiple of $100,000 (borrowings, conversions or
prepayments of Loans of different Types or, in the case of Eurocurrency Loans,
having different Interest Periods, at the same time hereunder to be deemed
separate borrowings, conversions and prepayments for purposes of the foregoing,

Multi-Currency and equal to or greater than an amount the Dollar Equivalent of
which is $1,000,000.

Loans on the last day of the then current Interest Period for such Loans or (if
outstanding as ABR Loans) will remain as, or (if not then outstanding) will be

                  5.6 NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT. Unless
the Administrative Agent or the Multi-Currency Payment Agent, as the case may
be, shall have been notified by a US$ Lender, US$-Canadian Lender,
Multi-Currency Lender, Tranche A Term Lender, Tranche B Term Lender or a
Borrower (the "PAYOR") prior to the date on which such Lender is to make payment
to the Administrative Agent or the Multi-Currency Payment Agent, as the case may
be, of the proceeds of a Loan to be made by it hereunder or the Borrower is to
make a payment to the Administrative Agent or the Multi-Currency Payment Agent,
as the case may be, for the account of one or more of the Lenders, as the case
may be (such payment being herein called the "REQUIRED PAYMENT"), which notice
shall be effective upon receipt, that the Payor does not intend to make the
Required Payment to the Administrative Agent or the Multi-Currency Payment
Agent, as the case may be, the Administrative Agent or the Multi-Currency
Payment Agent, as the case may be, may assume that the Required Payment has been
made and may, in reliance upon such assumption (but shall not be required to),
make the amount thereof available to the intended recipient on such date and, if
the Payor has not in fact made the Required Payment to the Administrative Agent
or the Multi-Currency Payment Agent, as the case may be, the recipient of such
payment shall, on demand, pay to the Administrative Agent or the Multi-Currency
Payment Agent, as the case may be, the amount made available to it together with
interest thereon in respect of the period commencing on the date such amount was
so made available by the Administrative Agent or the Multi-Currency Payment
Agent, as the case may be, until the date the Administrative Agent or the
Multi-Currency Payment Agent, as the case may be, recovers such amount at a rate
per annum equal to the Federal Funds Effective Rate for such

<PAGE>
                                                                              51

period or, in the case of an amount payable in a currency other than Dollars,
the rate determined by the Administrative Agent in its discretion of the
appropriate rate for interbank settlements.

                  5.7 SHARING OF PAYMENTS; WAIVER OF ENFORCEMENT WITHOUT
CONSENT. ETC. (a) Each Borrower agrees that, in addition to (and without
limitation of) any right of set-off, banker's lien or counterclaim a Lender may
otherwise have, each Lender shall be entitled, at its option, to offset balances
held by it or its affiliates for the account of the such Borrower at any of
their offices, in Dollars or in any other currency, against any principal of or
interest on any of such Lender's Loans or Reimbursement Obligations to such
Borrower hereunder, or any other obligation of such Borrower hereunder, which is
not paid when due (regardless of whether such balances are then due to such
Borrower), in which case it shall promptly notify the Company, the relevant
Borrower and the Administrative Agent (or the Multi-Currency Payment Agent, as
the case may be) thereof, provided that such Lender's failure to give such
notice shall not affect the validity thereof. Each Borrower agrees, to the
fullest extent it may effectively do so under applicable law, that any Person
purchasing a participation in the Loans to such Borrower made, or other
obligations held, by another Person, whether or not acquired pursuant to the
foregoing arrangements, may exercise all rights of set-off, banker's lien,
counterclaim or similar rights with respect to such participation as fully as if
such Lender were a direct holder of such Loans or other obligations in the
amount of such participation.

                  (b) If a Lender shall obtain payment of any principal of or
interest on any Loan made by it under this Agreement, or on any other obligation
then due to such Lender hereunder, through the exercise of any right of set-off,
banker's lien, counterclaim or similar right, or otherwise, it shall promptly
notify the Administrative Agent (or the Multi-Currency Payment Agent, as the
case may be) and purchase from the other Lenders participations in the Loans
made, or other obligations held, by the other Lenders in such amounts, and make
such other adjustments from time to time as shall be equitable to the end that
all the Lenders shall share the benefit of such payment (net of any expenses
which may be incurred by such Lender in obtaining or preserving such benefit)
pro rata in accordance with the unpaid principal and interest on the Loans or
other obligations then due to each of them. To such end all the Lenders shall
make appropriate adjustments among themselves (by the resale of participations
sold or otherwise) if such payment is rescinded or must otherwise be restored
(including the payment of interest to the extent that the Lender obligated to
return such funds is obligated to return interest).

                  (c) Nothing contained herein shall require any Lender to
exercise any right of set-off, banker's lien, counterclaim or similar right or
shall affect the right of any Lender to exercise, and retain the benefits of
exercising, any such right with respect to any other indebtedness or obligation
of any Borrower.

                  (d) This Section 5.07 is for the benefit of the Lenders only
and does not constitute a waiver of any rights against any Borrower or any of
their Subsidiaries or against any property held as security for any obligations
hereunder or under any other Basic Document.

                  5.8 WITHHOLDING TAX EXEMPTION. (a) At least five Business Days
prior to the first date on which interest or fees are payable hereunder for the
account of any Lender, each Lender that is not incorporated under the laws of
the United States of America or a state thereof agrees

<PAGE>
                                                                              52

that it will deliver, to the extent it has not so delivered under the Existing
Credit Agreement, to each of the Company and the Administrative Agent two duly
completed copies of either U.S. Internal Revenue Service Form W-8BEN or Form
W-8ECI (or any subsequent versions thereof or successors thereto), or, in the
case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax
under Section 871(h) or 881(c) of the Code with respect to payments of
"portfolio interest", a statement substantially in the form of Exhibit K (any
such certificate an "EXEMPTION CERTIFICATE") and a Form W-8BEN (or any
subsequent versions thereof or successors thereto), certifying in either case
that such Lender is entitled to receive payments under this Agreement and the
Notes without deduction or withholding of any United States federal income
taxes. Each Lender which so delivers a Form W-8BEN or Form W-8ECI further
undertakes to deliver to each of the Company and the Administrative Agent (or
the Multi-Currency Payment Agent, in the case of Multi-Currency Lenders) two
additional copies of such form (or a successor form) on or before the date that
such form expires or becomes obsolete or after the occurrence of any event
requiring a change in the most recent form so delivered by it, and such
amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Company or the Administrative Agent (or the Multi-Currency
Payment Agent, as the case may be), in each case certifying that such Lender is
entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes, unless an
event (including without limitation any change in treaty, law or regulation) has
occurred prior to the date on which any such delivery would otherwise be
required which renders all such forms inapplicable or which would prevent such
Lender from duly completing and delivering any such form with respect to it and
such Lender advises the Company and the Administrative Agent (or the
Multi-Currency Payment Agent, as the case may be) that it is not capable of
receiving payments without any deduction or withholding of United States federal
income tax.

                  (b) Each Lender that is not incorporated or organized under
the laws of the jurisdiction under which a Foreign Subsidiary Borrower is
incorporated or organized shall, upon request by such Foreign Subsidiary
Borrower, deliver to such Foreign Subsidiary Borrower or the applicable
Governmental Authority, any form or certificate required in order that any
payment by such Foreign Subsidiary Borrower under this Agreement or any Notes to
such Lender may be made free and clear of, and without deduction or withholding
for or on account of any tax (or to allow any such deduction or withholding to
be at a reduced rate) imposed on such payment under the laws of the jurisdiction
under which such Foreign Subsidiary Borrower is incorporated or organized,
PROVIDED that such Lender is legally entitled to complete, execute and deliver
such form or certificate and such completion, execution or submission would not
materially prejudice the legal position of such Lender.

                  (c) All payments made by a Borrower or the Canadian Borrower
under this Agreement shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding net income taxes and franchise taxes (imposed
in lieu of net income taxes) imposed on the Administrative Agent, the
Multi-Currency Payment Agent, the Canadian Administrative Agent or any Lender as
a result of a present or former connection between the Administrative Agent, the
Multi-Currency Payment Agent, the Canadian Administrative Agent or such Lender
and the jurisdiction of the Governmental

<PAGE>
                                                                              53

Authority imposing such tax or any political subdivision or taxing authority
thereof or therein (other than any such connection arising solely from the
Administrative Agent, the Multi-Currency Payment Agent or such Lender having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement or any other Loan Document). If any such non-excluded
taxes, levies, imposts, duties, charges, fees, deductions or withholdings
("NON-EXCLUDED TAXES") or other taxes are required to be withheld from any
amounts payable to the Administrative Agent, the Multi-Currency Payment Agent,
the Canadian Administrative Agent or any Lender hereunder, the amounts so
payable to the Administrative Agent, the Multi-Currency Payment Agent, the
Canadian Administrative Agent or such Lender shall be increased to the extent
necessary to yield to the Administrative Agent, the Multi-Currency Payment
Agent, the Canadian Administrative Agent or such Lender (after payment of all
Non-Excluded Taxes and other taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement, PROVIDED,
HOWEVER, that the relevant Borrower or the Canadian Borrower shall not be
required to increase any such amounts payable to any Lender with respect to any
Non-Excluded Taxes (i) that are attributable to such Lender's failure to comply
with the requirements of paragraph (a) or (b) of this Section or (ii) that are
United States withholding taxes imposed on amounts payable to such Lender at the
time the Lender becomes a party to this Agreement, except to the extent that
such Lender's assignor (if any) was entitled, at the time of assignment, to
receive additional amounts from such Borrower or the Canadian Borrower with
respect to such Non-Excluded Taxes pursuant to this paragraph.

                  5.9 JUDGMENT CURRENCY. If for the purpose of obtaining
judgment in any court it is necessary to convert a sum due from any Borrower or
the Canadian Borrower hereunder or under any of the Notes or the C$ Notes in the
currency expressed to be payable herein (the "specified currency") into another
currency, the parties hereto agree, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Administrative Agent could
purchase the specified currency with other such currency at the Administrative
Agent's New York Office on the Business Day that is on or immediately following
the day on which final judgment is given. The obligations of each Borrower or
the Canadian Borrower in respect of any sum due to any Lender, the
Administrative Agent, the Multi-Currency Payment Agent or the Canadian
Administrative Agent hereunder or under any Note or C$ Note shall,
notwithstanding any judgment in a currency other than the specified currency, be
discharged only to the extent that on the Business Day following receipt by such
Lender, the Administrative Agent, the Multi-Currency Payment Agent or the
Canadian Administrative Agent, as the case may be, of any sum adjudged to be so
due in such other currency such Lender, the Administrative Agent, the
Multi-Currency Payment Agent or the Canadian Administrative Agent as the case
may be, may in accordance with normal banking procedures purchase the specified
currency with such other currency. If the amount of the specified currency so
purchased is less than the sum originally due to such Lender, the Administrative
Agent, the Multi-Currency Payment Agent or the Canadian Administrative Agent, as
the case may be, in the specified currency, each Borrower and the Canadian
Borrower agrees, to the fullest extent it may effectively do so, as a separate
obligation and notwithstanding any such judgment, to indemnify such Lender, the
Administrative Agent, the Multi-Currency Payment Agent or the Canadian
Administrative Agent, as the case may be, against such loss, and if the amount
of the specified currency so purchased exceeds the sum originally due to any
Lender, the Administrative Agent the Multi-Currency Payment Agent or the
Canadian

                                                                              54

Administrative Agent, as the case may be, in the specified currency, such Lender
or the Administrative Agent, or the Multi-Currency Payment Agent, or the
Canadian Administrative Agent, as the case may be, agrees to remit such excess
to the appropriate Borrower or the Canadian Borrower.

                  Section 6.  YIELD PROTECTION AND ILLEGALITY.

                  6.1  ADDITIONAL COSTS.

                  (a) Each Borrower shall pay to the Administrative Agent for
the account of each Lender from time to time such amounts as such Lender may
determine to be necessary to compensate it for any costs incurred by such Lender
which such Lender determines are attributable to its making or maintaining of
any Eurocurrency Loans hereunder to such Borrower or its obligation to make any
of such Loans hereunder to such Borrower, or any reduction in any amount
receivable by such Lender in respect of any of such Loans or such obligation
(such increases in costs and reductions in amounts receivable being herein
called "ADDITIONAL COSTS"), in each case resulting from any Regulatory Change
which:

                  (i) changes the basis of taxation of any amounts payable to
         such Lender under this Agreement or its Notes in respect of any of such
         Loans (other than changes which affect taxes measured by or imposed on
         the overall net income of such Lender or of its Applicable Lending
         Office any of such Loans by the jurisdiction in which such Lender has
         its principal office or such Applicable Lending Office); or

                  (ii) imposes or modifies any reserve, special deposit or
         similar requirements relating to any extensions of credit or other
         assets of, or any deposits with or other liabilities of, such Lender
         (including any of such Loans or any deposits referred to in the
         definition of "Eurocurrency Base Rate" in Section 1.01 hereof); or

                  (iii) imposes any other condition affecting this Agreement (or
         any of such extensions of credit or liabilities).

Each Lender will notify the relevant Borrower through the Administrative Agent
of any event occurring after the date of this Agreement which will entitle such
Lender to compensation pursuant to this Section 6.01(a) (an "ADDITIONAL COST
EVENT") as promptly as practicable after it obtains knowledge thereof and
determines to request such compensation, and (if so requested by the Company
through the Administrative Agent) will designate a different Applicable Lending
Office for the Eurocurrency Loans of such Lender if such designation will avoid
the need for, or reduce the amount of, such compensation and will not, in the
sole opinion of such Lender, be disadvantageous to such Lender (provided that
such Lender shall have no obligation to so designate an Applicable Lending
Office located in the United States of America) PROVIDED, that a Borrower shall
not be obligated to compensate such Lender for any such Additional Costs
incurred more than 180 days prior to the time the Lender first notifies such
Borrower of such Additional Cost Event. Each Lender will furnish the relevant
Borrower with a statement setting forth the calculations and the basis therefor,
in each case in reasonable detail, and amount of each request by such Lender for
compensation under this Section 6.01(a). If any Lender requests

<PAGE>

                                                                              55

compensation from a Borrower under this Section 6.01(a), the relevant Borrower
may, by notice to such Lender through the Administrative Agent, suspend the
obligation of such Lender to make additional Eurocurrency Loans to such Borrower
until the Regulatory Change giving rise to such request ceases to be in effect
(in which case the provisions of Section 6.04 hereof shall be applicable).

                  (b) Without limiting the effect of the foregoing provisions of
this Section 6.01, in the event that, by reason of any Regulatory Change, any
Lender either (i) incurs Additional Costs based on or measured by the excess
above a specified level of the amount of a category of deposits or other
liabilities of such Lender which includes deposits by reference to which the
interest rate on Eurocurrency Loans is determined as provided in this Agreement
or a category of extensions of credit or other assets of such Lender which
includes Eurocurrency Loans or (ii) becomes subject to restrictions on the
amount of such a category of liabilities or assets which it may hold, then, if
such Lender so elects by notice to the relevant Borrower (with a copy to the
Administrative Agent), the obligation of such Lender to make Eurocurrency Loans
hereunder shall be suspended until the date such Regulatory Change ceases to be
in effect (in which case the provisions of Section 6.04 hereof shall be
applicable).

                  (c) Determinations and allocations by any Lender for purposes
of this Section 6.01 of the effect of any Regulatory Change on its costs of
maintaining its obligations to make Loans or of making or maintaining Loans or
on amounts receivable by it in respect of Loans, and of the additional amounts
required to compensate such Lender in respect of any Additional Costs, shall be
conclusive absent manifest error, provided that such determinations and
allocations are made on a reasonable basis.

                  (d) If any Lender demands compensation under this Section, the
relevant Borrower may, at any time upon at least three (3) Business Days' prior
notice to such Lender through the Administrative Agent, convert in full the then
outstanding Eurocurrency Loans of such Lender (in which case the relevant
Borrower shall be obligated, if such conversion is made on a day that is not the
last day of the then current Interest Period applicable to such affected
Eurocurrency Loan, to reimburse such Lender, in accordance with Section 6.05,
for any resulting loss or expense incurred by it) to an ABR Loan.

                  6.2 LIMITATION ON TYPES OF LOANS. Anything herein to the
contrary notwithstanding, if, with respect to any Loans that are Eurocurrency
Loans:

                  (a) the Administrative Agent determines (which determination
         shall be conclusive) that quotations of interest rates for the relevant
         deposits referred to in the definition of "Eurocurrency Base Rate" in
         Section 1.01 hereof are not being provided by the Reference Lenders in
         the relevant amounts or for the relevant maturities for purposes of
         determining the rate of interest for such Loans for Interest Periods
         therefor as provided in this Agreement; or

                  (b) the Majority Lenders determine (which determination shall
         be conclusive) and notify the Administrative Agent that the relevant
         rates of interest referred to in the definition of "Eurocurrency Base
         Rate" in Section 1.01 thereof upon the basis of which

<PAGE>

                                                                              56

         the rates of interest for such Loans are to be determined do not
         accurately reflect the cost to such Lenders of making or maintaining
         such Loans for Interest Periods therefor;

then the Administrative Agent shall promptly notify the relevant Borrower and
each Lender thereof, and so long as such condition remains in effect, the
Lenders shall be under no obligation to make Eurocurrency Loans or to convert
ABR Loans into Eurocurrency Loans and the relevant Borrower shall, on the last
day(s) of the then current Interest Period(s) for the outstanding Eurocurrency
Loans, either prepay such Loans or convert such Loans into ABR Loans in
accordance with Section 3.02 hereof.

                  6.3 ILLEGALITY. Notwithstanding any other provision of this
Agreement to the contrary, in the event that it becomes unlawful for any Lender
or its Applicable Lending Office to (a) honor its obligation to make
Eurocurrency Loans hereunder, or (b) maintain Eurocurrency Loans hereunder, then
such Lender shall promptly notify the relevant Borrower thereof through the
Administrative Agent and such Lender's obligation to make Eurocurrency Loans
hereunder shall be suspended until such time as such Lender may again make and
maintain Eurocurrency Loans (in which case the provisions of Section 6.04 hereof
shall be applicable).

                  6.4 SUBSTITUTE ABR LOANS. If the obligation of any Lender to
make Eurocurrency Loans shall be suspended pursuant to Section 6.01, 6.02 or
6.03 hereof, all Loans in Dollars which would otherwise be made by such Lender
as Eurocurrency Loans shall be made instead as ABR Loans (and, if an event
referred to in Section 6.01 (b)or 6.03 hereof has occurred and such Lender so
requests by notice to the relevant Borrower with a copy to the Administrative
Agent, each Dollar-denominated Eurocurrency Loan of such Lender then outstanding
shall be automatically converted into an ABR Loan on the date specified by such
Lender in such notice) and, to the extent that Eurocurrency Loans are so made as
(or converted into) ABR Loans, all payments of principal which would otherwise
be applied to such Eurocurrency Loans shall be applied instead to such ABR
Loans.

                  6.5 COMPENSATION. Each Borrower shall pay to the
Administrative Agent for the account of each Lender, upon the request of such
Lender through the Administrative Agent, such amount or amounts as shall be
sufficient (in the reasonable opinion of such Lender) to compensate it for any
loss, cost or expense incurred by it as a result of:

                  (a) any payment, prepayment or conversion (including an
         automatic conversion pursuant to Section 10.02 hereof) of a
         Eurocurrency Loan made by such Lender to such Borrower on a date other
         than the last day of an Interest Period for such Loan;

                  (b) any failure by a Borrower to borrow a Eurocurrency Loan to
         be made by such Lender to such Borrower on the date for such borrowing
         specified in the relevant notice of borrowing under Section 5.05
         hereof;

                  (c) any failure by a Borrower to prepay a Eurocurrency Loan on
         the date specified in a notice of prepayment; or

                  (d) any substitution of a Lender under Section 6.07 hereof on
         a date other than the last day of an Interest Period for each Loan of
         such Lender;

<PAGE>

                                                                              57

but excluding, in any event, loss of margin for the period after any such
payment, prepayment or conversion or failure to borrow; PROVIDED that such
Lender shall have delivered to the relevant Borrower a certificate as to the
amount of such loss and expense along with the calculation and the basis
therefor, in each case in reasonable detail.

                  6.6 CAPITAL ADEQUACY. If any Lender shall determine that the
adoption of any applicable law, rule, regulation or treaty regarding capital
adequacy after the date hereof, or any change therein after the date hereof, or
any change after the date hereof in the interpretation or administration thereof
by any governmental authority, central bank or comparable agency charged with
the interpretation or administration thereof, or compliance by any Lender (or
its Applicable Lending Office) with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on capital of such Lender or any Person controlling such Lender (a
"PARENT") as a consequence of its obligations hereunder to a level below that
which such Lender (or its Parent) could have achieved but for such adoption,
change or compliance (taking into consideration its policies with respect to
capital adequacy) by an amount deemed by such Lender to be material, then from
time to time, within 15 days after demand by such Lender (with a copy to the
Administrative Agent), the relevant Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such reduction.
A statement of any Lender claiming compensation under this Section and setting
forth the additional amount or amounts to be paid to it hereunder shall be
conclusive absent manifest error; provided that the determination thereof is
made on a reasonable basis; and provided further that a Borrower shall not be
obligated to compensate such Lender for any such reduction occurring more than
180 days prior to the time such Lender first notifies such Borrower of such
adoption, implementation, change or compliance. In determining such amount, such
Lender may use any reasonable averaging and attribution methods.

                  6.7 SUBSTITUTION OF LENDER. If (i) the obligation of any
Lender to make Eurocurrency Loans or the right of a Borrower to convert ABR
Loans of any Lender to Eurocurrency Loans has been suspended pursuant to Section
6.03, or (ii) any Lender has demanded compensation under Section 6.01, 6.06 or
6.09, the relevant Borrower shall have the right, with the assistance of the
Administrative Agent, to seek a substitute bank or banks (which may be one or
more of the Lenders) satisfactory to such Borrower and the Administrative Agent
to purchase the Notes and assume the Commitments of such Lender. Any such Lender
shall be obligated to sell the Notes for cash without recourse to such
substitute bank or banks and to execute and deliver an appropriately completed
assignment and assumption agreement reasonably satisfactory to the
Administrative Agent and the relevant Borrower and any other document or perform
any act reasonably necessary to effect the assumption of the rights and
obligations of such substitute bank or banks.

                  6.8 ADDITIONAL COSTS IN RESPECT OF LETTERS OF CREDIT. Without
limiting the obligations of the Borrowers under Section 6.01 hereof (but without
duplication), if as a result of any Regulatory Change or any risk-based capital
guideline or other requirement heretofore or hereafter issued by any government
or governmental or supervisory authority implementing at the national level the
Basle Accord there shall be imposed, modified or deemed applicable any

<PAGE>

                                                                              58

tax, reserve, special deposit, capital adequacy or similar requirement against
or with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder and the result shall be to increase the cost to any Lender or
Lenders of issuing (or purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Lender hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Lender's or Lenders' reasonable
allocation of the aggregate of such increases or reductions resulting from such
event), then, upon demand by such Lender or Lenders (through the Administrative
Agent), the relevant Borrower shall pay immediately to the Administrative Agent
for account of such Lender or Lenders, from time to time as specified by such
Lender or Lenders (through the Administrative Agent), such additional amounts as
shall be sufficient to compensate such Lender or Lenders (through the
Administrative Agent) for such increased costs or reductions in amount. A
statement as to such increased costs or reductions in amount incurred by any
such Lender or Lenders, showing calculations and the basis therefor in
reasonable detail, submitted by such Lender or Lenders to the relevant Borrower,
shall be conclusive in the absence of manifest error as to the amount thereof.

                  6.9 FOREIGN BORROWER COSTS. (a) If the cost to any Lender of
making or maintaining any Loan to a Foreign Subsidiary Borrower is increased, or
the amount of any sum received or receivable by any Lender (or its Applicable
Lending Office) is reduced, by an amount deemed by such Lender to be material,
by reason of the fact that such Borrower is organized under the laws of, or
principally conducts its business in, a jurisdiction or jurisdictions outside
the United States of America, such Borrower shall indemnify such Lender for such
increased cost or reduction within 15 days after demand by such Lender (with a
copy to the Administrative Agent). A certificate of such Lender claiming
compensation under this subsection (a) and setting forth the additional amount
or amounts to be paid to it hereunder, together with calculations in reasonable
detail supporting such amounts, shall be conclusive in the absence of clearly
demonstrable error. No such compensation may be claimed (x) in respect of any
Loan for any period prior to the date 90 days before the date of notice by such
Lender to the Company of its intention to make claims therefor or (y) to the
extent such Lender was aware of such cost or reduction at the time the related
Loan was made.

                  (b) Each Lender will promptly notify the Company and the
Administrative Agent of any event of which it has knowledge that will entitle
such Lender to additional interest or payments pursuant to the foregoing
subsection (a) and will designate a different Applicable Lending Office, if, in
the judgment of such Lender, such designation will avoid the need for, or reduce
the amount of, such compensation and will not be otherwise disadvantageous to
such Lender.

                  7.1 EFFECTIVE DATE. This Agreement shall become effective on

                  (a)  no Default shall have occurred and be continuing;

                  (b) the representations and warranties made by each of the

         of Credit, as the case may be, and the related incurrence of

Borrower to the effect set forth in the preceding sentence (both as of the date
of such notice and, unless the Company, the Canadian Borrower or such other
Borrower otherwise notifies the Administrative Agent prior to the date of such
borrowing or issuance, as of the date of such borrowing or issuance).

                  7.3 FIRST LOAN TO A SUBSIDIARY BORROWER. The obligation of
each Lender to make a Loan on the occasion of the first borrowing by each
Subsidiary Borrower is subject to the receipt by the Administrative Agent of all

Subsidiary Borrower, the corporate or other legal authority for and the validity
of its Election to Participate, this Agreement and the Notes of such Subsidiary
Borrower, and for any other matters relevant thereto, all in form and substance
reasonably satisfactory to the Administrative Agent.

                  Section 8. REPRESENTATIONS AND WARRANTIES. The Company
represents and warrants to the Lenders and the Administrative Agent, as of the
Effective Date and on the date of each Loan and of the issuance of each Letter
of Credit, as follows:

                  8.1 CORPORATE EXISTENCE. Each of the Company and its
Subsidiaries: (a) is a corporation duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation; (b) has all
requisite corporate power, and has all governmental licenses, authorizations,
consents, permits and approvals (including any license, authorization, consent,
permit and approval required under any Environmental Law) necessary to own its
assets and carry on its business as now being or as proposed to be conducted
(except such licenses, authorizations, consents and approvals the lack of which,
in the aggregate, will not have a Material Adverse Effect); and (c) is qualified
to do business in all jurisdictions in which the nature of the business
conducted by it makes such qualification necessary and where failure so to
qualify would have a Material Adverse Effect.

                  8.2  INFORMATION.

                  (a) The Company has heretofore furnished to each of the
Lenders the consolidated balance sheets of (i) Old IMI and its Subsidiaries as

                  (b) The Company has disclosed to the Lenders in writing any
and all facts (other than general economic conditions) which materially and
adversely affect or may materially and adversely affect (to the extent it can

the Subsidiary Guarantors to perform its obligations under each Basic Document
to which it is a party or the ability of the Company or any Subsidiary of the
Company to conduct its activities or operations in the normal course of business
at any of its owned or leased properties. The information, reports, financial

Documents or included herein or therein or delivered pursuant hereto or thereto,
when taken as a whole do not contain any untrue statement of material fact or
omit to state any material fact necessary to make the statements herein or

preparation of such information, report, financial statement, exhibit or
schedule. All written information furnished after the date hereof by the Company
and its Subsidiaries to the Administrative Agent and the Lenders and required in
connection with this Agreement and the other Basic Documents and the

estimates, on the date as of which such information is stated or certified.

                  (c) Since June 30, 2000, there has been no material adverse
change in the business, assets, property, condition (financial or otherwise) or
prospects of the Company and its Subsidiaries taken as a whole or, to the
knowledge of the Company, in the ability of the Company, the Canadian Borrower,
any other Borrower or any of the Subsidiary Guarantors to perform its
obligations under each Basic Document to which it is a party.

any proceedings by or before any Governmental Authority or agency, now pending
or, to the knowledge of the Company, threatened against or affecting the Company
or any of its Subsidiaries in which there is a reasonable possibility of an
adverse decision which could have a Material Adverse Effect or, to the knowledge
of the Company, which could have a material adverse effect on the ability of the
Company, the Canadian Borrower, any other Borrower or any of the Subsidiary
Guarantors to perform its obligations under each Basic Document to which it is a
party.

                  8.4 NO BREACH. None of the execution and delivery of the Basic
Documents, the consummation of the transactions therein contemplated or
compliance with the terms and provisions thereof will conflict with or result in
a breach of, or require any consent under, the certificate of incorporation or
by-laws of the Company or any of its Subsidiaries, or any applicable law or
regulation, or any order, writ, injunction or decree of any court or
Governmental Authority, or any Basic Document, any other material agreement or
instrument to which the Company or any of its Subsidiaries is a party or by
which it is bound or to which it is

<PAGE>

                                                                              63

subject, or constitute a default under any such lease, agreement or instrument,
or (except for the Liens created pursuant to, or permitted by, this Agreement
and the Security Documents) result in the creation or imposition of any Lien
upon any of the revenues or assets of the Company or any of its Subsidiaries
pursuant to the terms of any such agreement or instrument.

                  8.5 CORPORATE ACTION. Each of the Company, the Canadian
Borrower and the Subsidiary Guarantors has all necessary corporate power and
authority to execute, deliver and perform its obligations under the Basic
Documents to which it is a party; the execution, delivery and performance by the
Company, the Canadian Borrower and the Subsidiary Guarantors of the Basic
Documents to which they are parties have been duly authorized by all necessary
corporate action; and this Agreement has been duly and validly executed and
delivered by each of the Company and the Canadian Borrower and constitutes its
legal, valid and binding obligation and each of the other Basic Documents to
which the Company, the Canadian Borrower or any of the Subsidiary Guarantors is
to be a party constitute its legal, valid and binding obligation, in each case

shall prevent (i) the merger and dissolution of any Subsidiary of the Company
into the Company or any Wholly-Owned Subsidiary of the Company so long as the
Company or such Wholly-Owned Subsidiary is the surviving corporation (and, if
such Subsidiary is not an Excluded Subsidiary prior to such merger or
dissolution, the surviving corporation (if not the Company) is not an Excluded

Company and any such Subsidiary.

and will cause each of its Subsidiaries to comply, with the requirements of all
applicable laws, rules, regulations and orders of any governmental body or
regulatory authority (including, without limitation, ERISA and all Environmental

contested in good faith and by proper proceedings.

                  9.7 LITIGATION. The Company will promptly give to the
Administrative Agent (which shall promptly notify each Lender) notice in writing

to, take such action from time to time as shall be necessary to ensure that the
Company and each of its Subsidiaries at all times owns (i) all of the issued and
outstanding shares of each class of Capital Stock of each of such Person's
Subsidiaries (other than, in each case, Capital Stock of Excluded Subsidiaries)

additional shares of Capital Stock shall be issued by any Subsidiary of the
Company, or any Subsidiary shall be acquired, the Company agrees (so long as the
certificates evidencing such shares of stock are not subject to a lien permitted
under Section 9.13(vii) hereof, and in any event subject to clause (c) below)
forthwith to deliver to the Administrative Agent pursuant to the Security
Documents the certificates evidencing such shares of stock, accompanied by

SPE) to become parties to the Subsidiary Guaranty or to execute and deliver such
other guaranties, in form and substance satisfactory to the Majority Lenders,
guaranteeing payment of the Company's obligations hereunder. Any such request

                  its Domestic Subsidiaries to the Administrative Agent under
                  the Security Documents; and

                         (III) the Company and its Subsidiaries shall not be
                  required to pledge the stock of any other Excluded Subsidiary.

                  (d) The Company will not permit any of its Subsidiaries (other
than Excluded Subsidiaries or any SPE acting pursuant to the terms of an
Accounts Receivable Financing permitted by the terms of this Agreement) to enter
into, after the date hereof, any indenture, agreement, instrument or other
arrangement (other than the Senior Subordinated Debt Indentures) that, directly
or indirectly, prohibits or restrains, or has the effect of prohibiting or
restraining, or imposes materially adverse conditions upon, the incurrence or

         within 30 days from the date of entry thereof, or the Company or such

         period during which execution of the same shall have been stayed,
         appeal therefrom and cause the execution thereof to be stayed during
         such appeal; or

                  (i) the Company or any member of the Controlled Group shall

                  (k) (i) any Security Document or the Company Guaranty or the
         Subsidiary Guaranty shall cease, for any reason, to be in full force

THEREUPON: the Administrative Agent may (and, if directed by the Majority
Lenders, shall) (a) declare the Commitments terminated (whereupon the
Commitments shall be terminated) and/or (b) declare the principal amount then
outstanding of and the accrued interest on the Loans, the Reimbursement
Obligations, and commitment fees and all other amounts payable hereunder and
under the Notes and the C$ Notes to be forthwith due and payable, whereupon such
amounts shall be and become immediately due and payable, without notice
(including, without limitation, notice of intent to accelerate), presentment,
demand, protest or other formalities of any kind, all of which are hereby
expressly waived by the Borrowers and the Canadian Borrower; PROVIDED that in
the case of the occurrence of an Event of Default with respect to the Company
referred to in clause (f) or (g) of this Section 10.01, the Commitments shall be
automatically terminated and the principal amount then outstanding of and the
accrued interest on the Loans, the Reimbursement Obligations, and commitment
fees and all other amounts payable hereunder and under the Notes and the C$
Notes shall be and become automatically and immediately due and payable, without
notice (including, without limitation, notice of intent to accelerate),
presentment, demand, protest or other formalities of any kind, all of which are
hereby expressly waived by the Company and the Canadian Borrower.

                  In addition, upon the occurrence and during the continuance of
any Event of Default (if the Administrative Agent has declared the principal
amount then outstanding of, and accrued interest on, the Loans and all other
amounts payable by the Company, the Canadian Borrower or any other Borrower
hereunder and under the Notes and the C$ Notes to be due and payable), the
Company agrees that it shall, if requested by the Administrative Agent or the
Majority Lenders through the Administrative Agent (and, in the case of any Event
of Default referred to in clause (f) or (g) of this Section 10.01 with respect
to the Company, forthwith, without any demand or the taking of any other action
by the Administrative Agent or such Lenders) provide cover for the Letter of
Credit Liabilities by paying to the Administrative Agent immediately available
funds in an amount equal to the then aggregate undrawn stated amount of all
Letters of Credit, which funds shall be held by the Administrative Agent in the
Collateral Account as collateral security in the first instance for the Letter
of Credit Liabilities.

                  10.2 RATABLE TREATMENT OF LENDERS. In the event that the Loans
and the Reimbursement Obligations shall be declared or become immediately due
and payable on any date (the "ACCELERATION DATE") pursuant to Section 10.01
hereof, the Borrowers, the Canadian Borrower and the Revolving Lenders agree
that the outstanding Revolving Loans and Reimbursement Obligations and accrued
but unpaid interest thereon not denominated in Dollars shall be automatically
converted to Dollars on the Acceleration Date at the then applicable Exchange
Rate and any Reimbursement Obligation not denominated in Dollars thereafter
arising shall be automatically converted to Dollars on the date of the drawing
giving rise thereto under the relevant Letter of Credit at the then applicable
Exchange Rate. The Revolving Lenders hereby irrevocably agree for the benefit of
each other (and not for the benefit of the Borrowers,

<PAGE>

                                                                              83

the Canadian Borrower or the other Obligors) that, effective as of the
Acceleration Date, each Revolving Lender shall acquire participations in each
then outstanding Revolving Loan and Letter of Credit Liability in proportion to
the aggregate Commitments of such Revolving Lender to the aggregate Revolving
Commitments of all the Revolving Lenders, in each case determined immediately
prior to the Acceleration Date (such Revolving Lender's "PROPORTION"). On or
promptly following the Acceleration Date, the Administrative Agent shall
determine for each Revolving Lender the difference between (a) such Revolving
Lender's Proportion of the aggregate principal amount of the outstanding
Revolving Loans and Reimbursement Obligations on the Acceleration Date after
giving effect to the automatic conversion to Dollars and (b) the aggregate
principal amount of such Revolving Lender's actual outstanding Revolving Loans
and Reimbursement Obligations on the Acceleration Date after giving effect to
the automatic conversions to Dollars. Each Revolving Lender whose difference is
positive shall make a payment which is equal to such difference to the
Administrative Agent in Dollars in immediately available funds on a date set by
the Administrative Agent promptly following the Acceleration Date. The
Administrative Agent shall distribute such payment to the Revolving Lenders
whose differences are negative, with such distribution to be ratable based upon
the respective amounts of such negative differences. On each subsequent date on
which a Reimbursement Obligation arises by virtue of a draw on a Letter of
Credit, each Revolving Lender shall, promptly after being notified thereof, make
a payment to the Issuing Lender equal to its Proportion of such Reimbursement
Obligation. To the extent that any Revolving Lender shall fail to pay any amount
required to be paid pursuant to this Section 10.02 on the due date therefor,
such Revolving Lender shall pay interest to the Administrative Agent for ratable
distribution to the Revolving Lenders or Issuing Lenders entitled thereto on
such amount from and including such due date to but excluding the date such
payment is made at a rate per annum equal to the Federal Funds Effective Rate,
PROVIDED that if such Revolving Lender shall fail to make such payment within
three Business Days of such due date, then, retroactively to the due date, such
Revolving Lender shall be obligated to pay interest on such amount at the ABR
Rate.

                                                                             84

                  11.1 APPOINTMENT POWERS AND IMMUNITIES. Each Lender hereby
irrevocably appoints and authorizes the Administrative Agent to act as its
agent hereunder and under the other Basic Documents with such powers as are
specifically delegated to the Administrative Agent by the terms hereof and
thereof, together with such other powers as are reasonably incidental
thereto. The Administrative Agent (which term as used in this Section 11
shall include reference to its affiliates and its own and its affiliates'
officers, directors, employees and agents): (a) shall have no duties or
responsibilities except those expressly set forth in this Agreement and the
other Basic Documents, and shall not by reason of this Agreement or any other
Basic Document be a trustee for any Lender; (b) shall not be responsible to
the Lenders for any recitals, statements, representations or warranties
contained in this Agreement or any other Basic Document, or in any
certificate or other document referred to or provided for in, or received by
any of them under, this Agreement or any other Basic Document, or for the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any other Basic Document or any other document referred to
or provided for herein or therein or for any failure by the Company, the
Canadian Borrower, any other Borrower or any of the Subsidiary Guarantors or
any other Person to perform any of its obligations hereunder or thereunder;
(c) shall not be required to initiate or conduct any litigation or collection
proceedings hereunder or under any other Basic Document except to the extent
requested by the Majority Lenders; and (d) shall not be responsible for any
action taken or omitted to be taken by it hereunder or under any other Basic
Document or any other document or instrument referred to or provided for
herein or therein or in connection herewith or therewith, except for its own
gross negligence or willful misconduct. The Administrative Agent may employ
agents and attorneys-in-fact and shall not be responsible for the negligence
or misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care.

                  11.2 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative
Agent shall be entitled to rely upon any certification, notice or other
communication (including any thereof by telephone, telex, telegram or cable)
believed by it to be genuine and correct and to have been signed or sent by
or on behalf of the proper Person or Persons, and upon advice and statements
of legal counsel, independent accountants and other experts selected by the
Administrative Agent. As to any matters not expressly provided for by this
Agreement or any other Basic Document, the Administrative Agent shall in all
cases be fully protected in acting, or in refraining from acting, hereunder
and thereunder in accordance with instructions signed by the Majority Lenders
and such instructions of the Majority Lenders and any action taken or failure
to act pursuant thereto shall be binding on all of the Lenders.

                  11.3 DEFAULTS. The Administrative Agent shall not be deemed
to have knowledge of the occurrence of a Default (other than a Default of the
type specified in Section 10.01(a)) unless the Administrative Agent has
received notice from a Lender or the Company, the Canadian Borrower or any
other Borrower specifying such Default and stating that such notice is a
"Notice of Default". In the event that the Administrative Agent receives such
a notice of the occurrence of a Default, the Administrative Agent shall give
prompt notice thereof to the Lenders. The Administrative Agent shall (subject
to Section 11.07 hereof) take such action with respect to such Default as
shall be directed by the Majority Lenders, provided that, unless and until
the Administrative Agent shall have received such directions, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with

<PAGE>
                                                                            85

respect to such Default as it shall deem advisable in the best interests of
the Lenders. The Administrative Agent shall deliver to the Lenders a copy of
any written declaration made pursuant to the second to last paragraph of
Section 10.01 hereof.

                  11.4 RIGHTS AS A LENDER. With respect to its Commitments
and the Loans made by it, the Administrative Agent in its capacity as a
Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as the
Administrative Agent and the term "Lender" or "Lenders" shall, unless the
context otherwise indicates, include the Administrative Agent in its
individual capacity. The Administrative Agent in its individual capacity may
(without having to account therefor to any Lender) accept deposits from, lend
money to and generally engage in any kind of banking, trust or other business
with the Company, the Canadian Borrower, the other Borrowers and the
Subsidiary Guarantors (and their respective Affiliates) as if it were not
acting as the Administrative Agent, and the Administrative Agent in its
individual capacity may accept fees and other consideration from the Company,
the Canadian Borrower or any other Borrower (in addition to the agency fees
and arrangement fees heretofore agreed to between the Company or the Canadian
Borrower and the Administrative Agent) for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

                  11.5 INDEMNIFICATION. The Lenders agree to indemnify the
Administrative Agent (to the extent not reimbursed under Section 12.03 or
12.04 hereof, but without limiting the obligations of the Company under said
Sections 12.03 and 12.04), ratably in accordance with the principal amount of
their respective Loans and Reimbursement Obligations outstanding, or if no
Loans or Reimbursement Obligations are outstanding, ratably in accordance
with their respective Commitments, for any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind and nature whatsoever which may be imposed on,
incurred by or asserted against the Administrative Agent in any way relating
to or arising out of this Agreement or any other Basic Document or any other
documents contemplated by or referred to herein or therein or the
transactions contemplated hereby or thereby (including, without limitation,
the costs and expenses which the Company is obligated to pay under Sections
12.03 and 12.04 hereof but excluding, unless a Default has occurred and is
continuing, normal administrative costs and expenses incident to the
performance of its agency duties hereunder) or the enforcement of any of the
terms hereof or thereof or of any such other documents, PROVIDED, that no
Lender shall be liable for any of the foregoing to the extent they arise from
the gross negligence or willful misconduct of the party to be indemnified.

                  11.6 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER
LENDERS. Each Lender agrees that it has, independently and without reliance
on the Administrative Agent or any other Lender, and based on such documents
and information as it has deemed appropriate, made its own credit analysis of
the Company and the Canadian Borrower and decision to enter into this
Agreement and that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its
own analysis and decisions in taking or not taking action under this
Agreement or any of the other Basic Documents. The Administrative Agent shall
not be required to keep itself informed as to the performance or observance
by the Company, the Canadian Borrower, the other Borrowers and the Subsidiary
Guarantors of this Agreement or any of the

<PAGE>
                                                                            86

other Basic Documents or any other document referred to or provided for
herein or therein or to inspect the properties or books of the Company, the
Canadian Borrower, any other Borrower or any of the Subsidiary Guarantors.
Except for notices, reports and other documents and information expressly
required to be furnished to the Lenders by the Administrative Agent hereunder
or the other Basic Documents, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition or business of the
Company, the Canadian Borrower, any other Borrower or any of the Subsidiary
Guarantors (or any of their affiliates) which may come into the possession of
the Administrative Agent.

                  11.7 FAILURE TO ACT. Except for action expressly required
of the Administrative Agent hereunder and under the other Basic Documents,
the Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction by the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action.

                  11.8 RESIGNATION OR REMOVAL OF ADMINISTRATIVE AGENT.
Subject to the appointment and acceptance of a successor Administrative Agent
as provided below, the Administrative Agent may resign at any time by giving
notice thereof to the Lenders and the Company and the Administrative Agent
may be removed at any time with or without cause by the Majority Lenders.
Upon any such resignation or removal the Majority Lenders shall have the
right to appoint a successor Administrative Agent reasonably acceptable to
the Company. Upon any such resignation or removal, the Administrative Agent
that resigned or was removed shall, to the extent that its annual agency fee
was paid in advance, pay to the Company an amount equal to such fee
multiplied by a fraction the numerator of which shall be the number of days
remaining on the date of such resignation or removal until the next
anniversary of the Effective Date, and the denominator of which shall be 365.
If no successor Administrative Agent shall have been so appointed by the
Majority Lenders and shall have accepted such appointment within 30 days
after the retiring Administrative Agent's giving of notice of resignation or
the Majority Lenders' removal of the retiring Administrative Agent (the
"Notice Date"), then the retiring Administrative Agent may, on behalf of the
Lenders, appoint a successor Administrative Agent reasonably acceptable to
the Company. Any successor Administrative Agent shall be (i) a Lender or (ii)
if no Lender has accepted such appointment within 30 days after the Notice
Date, a bank which has an office in New York, New York with a combined
capital and surplus of at least $250,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and
become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent, and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder. After any retiring
Administrative Agent's resignation or removal hereunder as Administrative
Agent, the provisions of this Section 11 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as the Administrative Agent.

                  11.9 CONSENTS UNDER BASIC DOCUMENTS. Without the prior written
consent of the Majority Lenders, the Administrative Agent will not consent to
any modification, supplement or

<PAGE>

                                                                            87

waiver under any of the Basic Documents or any of the other documents
described in Section 9.20 hereof.

                  11.10 COLLATERAL SUB-AGENTS. Each Lender by its execution
and delivery of this Agreement agrees, as contemplated by the Security
Documents, that, in the event it shall hold any Liquid Investments referred
to therein, such Liquid Investments shall be held in the name and under the
control of such Lender and such Lender shall hold such Liquid Investments as
a collateral sub-agent for the Administrative Agent thereunder.

                  11.11 MULTI-CURRENCY PAYMENT AGENT AND CANADIAN
ADMINISTRATIVE AGENT. The Multi-Currency Payment Agent referred to herein and
the Canadian Administrative Agent referred to in Annex A hereto shall be
deemed to be sub-agents of the Administrative Agent for all purposes of this
Agreement and entitled to the benefits of this Section 11.

                  11.12 ADDITIONAL MINISTERIAL POWERS OF THE AGENTS. The
Administrative Agent is hereby irrevocably authorized by each of the Lenders
to execute any document creating any Lien and to release any Lien covering
any asset of the Company or any of its Subsidiaries (including, without
limitation, any Facilities, accounts receivable or inventory) that is the
subject of a disposition, sale or assignment which is permitted under this
Agreement.

                  Section 12.  MISCELLANEOUS

                  12.1 WAIVER. No failure on the part of the Administrative
Agent or any Lender to exercise and no delay in exercising, and no course of
dealing with respect to, any right, power or privilege under any Basic
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any right, power or privilege thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or
privilege. The remedies provided in the Basic Documents are cumulative and
not exclusive of any remedies provided by law.

                  12.2 NOTICES. All notices and other communications provided

Administrative Agent, the Canadian Administrative Agent, the Lenders and each
affiliate thereof and their respective directors, officers, employees and

                  12.5 AMENDMENTS. ETC. No amendment or waiver of any
provision of this Agreement or the Notes or the C$ Notes, nor any consent to
any departure by the Company, the Canadian Borrower or any other Borrower
therefrom, shall in any event be effective unless the same shall be agreed or
consented to by the Majority Lenders and the Company, and each such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given; PROVIDED that no such change, waiver, discharge or
termination shall, without the consent of each Lender (other than a
defaulting Lender) directly affected thereby, (i) extend the Commitment
Termination Date (it being understood that any waiver of any prepayment of,
or the method of application of any prepayment to the amortization of, Loans
shall not constitute any such extension), or extend the stated maturity of
any Letter of Credit beyond the Commitment Termination Date, or extend the
scheduled date of any payment of principal of any Term Loan, or reduce the
rate or extend the time of payment of interest (other than as a result of
waiving the applicability of any post-default increase in interest rates) or

any Lender over the amount thereof then in effect (it being understood that a
waiver of any Default or Event of Default or of a mandatory reduction in

<PAGE>
                                                                            89

the Commitments shall not constitute a change in the terms of a Commitment of

(iii) reduce the percentage specified in, or (except to give effect to any

the Administrative Agent or (y) with respect to Annex A hereto without the
consent of the Canadian Borrower.

                  12.6 SUCCESSORS AND ASSIGNS. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns except that the Company, the Canadian
Borrower and the other Borrowers may not assign their rights or obligations
hereunder or under the Notes or the C$ Notes without the prior written
consent of all of the Lenders. Each Lender may assign all or a portion of its
rights and obligations under this Agreement and the Notes and the C$ Notes
(i) to any affiliate thereof (including, without limitation, (x) any entity
(whether a corporation, partnership, trust or otherwise) that is engaged in
making, purchasing, holding or otherwise investing in bank loans and similar
lines of credit in the ordinary course of its business and is administered or
managed by a Lender or an affiliate of such Lender and (y) with respect to
any Lender that is a fund which invests in bank loans and similar extensions
of credit, any other fund that invests in bank loans and similar extensions
of credit and is managed by the same investment advisor as such Lender or by
an affiliate of such investment advisor), (ii) to any other Lender or (iii)
with the consent of the Administrative Agent, of the Issuing Bank and of the
Company (provided, that the consent of the Company shall not be required if
an Event of Default hereunder shall have occurred and be continuing), which
consents shall not be unreasonably withheld or delayed, to any other bank or
financial institution (provided that any such partial assignment shall not,
unless the Company and the Administrative Agent otherwise agree, be less than
$5,000,000 (or, in the case of Tranche B Term Loans, $1,000,000), or if the
remainder of the Lender's Commitment or Term Loans is less than $5,000,000,
such lesser amount). Upon execution by the assignor and the assignee of an
instrument pursuant to which the assignee assumes such rights and
obligations, payment by such assignee to such assignor of an amount equal to
the purchase price agreed between such assignor and such assignee and
delivery to the Administrative Agent and the Company of an executed copy of
such instrument together with payment by such assignee to the Administrative
Agent of a processing fee of $2,500, such assignee shall have, to the extent
of such assignment (unless otherwise provided therein), the same rights and
benefits as it would have if it were a Lender hereunder and the assignor
shall be, to the extent of such assignment (unless otherwise provided
therein), released from its obligations under this Agreement. Each Lender may
(without the consent of any other party to this Agreement) sell
participations in all or any part of any Loan or Loans made by it to another
bank or other entity, in which event the participant shall not have any
rights under this Agreement (except as provided in the next succeeding
sentence hereof), or in the case of a Loan, such Lender's Note or C$ Note
(the participant's rights against such Lender in respect of such
participation to be those set forth in the agreement executed by such Lender
in

<PAGE>

                                                                            90

favor of the participant relating thereto, which agreement shall not give the
participant the right to consent to any modification, amendment or waiver
other than one described in clause (i), (ii), (iii),(iv), (v) or (vi) of
Section 12.05 hereof). Each of the Company and the Canadian Borrower agrees
that each participant shall be entitled to the benefits of Sections 5.07 and
6 of this Agreement and Section 3.8 of Annex A hereto with respect to its
participation; PROVIDED that no participant shall be entitled to receive any
greater amount pursuant to such Sections than the transferor Lender would
have been entitled to receive in respect of the amount of the participation
transferred by such transferor Lender to such participant had no such
transfer occurred. Each Lender may furnish any information concerning the
Company and its Subsidiaries in the possession of such Lender from time to
time to assignees and participants (including prospective assignees and
participants) which have agreed in writing to be bound by the provisions of
Section 12.07 hereof. The Administrative Agent and the Company may, for all
purposes of this Agreement, treat any Lender as the holder of any Note or C$
Note drawn to its order (and owner of the Loans evidenced thereby) until
written notice of assignment, participation or other transfer shall have been
received by them from such Lender.

                  In addition to the assignments and participations permitted
the foregoing provisions of this Section 12.06, any Lender may (without
notice to the Company, the Canadian Borrower, any other Borrower, the
Administrative Agent, the Issuing Bank or any other Lender and without
payment of any fee) assign and pledge all or any portion of its Loans and its
Notes (i) to any Federal Reserve Bank as collateral security pursuant to
Regulation A of the Board of Governors of the Federal Reserve System and any
Operating Circular issued by such Federal Reserve Bank and (ii) with respect
to any Lender which is a fund, to its trustee in support of its obligations
to its trustee, and such Loans and Notes shall be fully transferrable as
provided therein. No such assignment pursuant to the preceding sentence shall
release the assigning Lender from its obligations hereunder.

                  12.7 CONFIDENTIALITY. Each Lender agrees to exercise all
reasonable efforts to keep any information delivered or made available by or
on behalf of the Company to it which has not been publicly disclosed
confidential from anyone other than persons employed or retained by such
Lender who are or are expected to become engaged in evaluating, approving,
structuring or administering the Loans; PROVIDED that nothing herein shall
prevent any Lender from disclosing such information (i) to any other Lender,
(ii) to the officers, directors, employees, agents, attorneys and accountants
of such Lender or its affiliates who have a need to know such information in
accordance with customary banking practices and who receive such information
having been made aware of the restrictions set forth in this Section, (iii)
upon the order of any court or administrative agency, (iv) upon the request
or demand of any regulatory agency or authority having jurisdiction over such
Lender, (v) to the extent reasonably required in connection with any
litigation to which the Administrative Agent, any Lender, the Company, the
Canadian Borrower, any other Borrower, any Subsidiary Guarantor or their
respective affiliates may be a party, (vi) to the extent reasonably required
in connection with the exercise of any remedy hereunder, (vii) to such
Lender's legal counsel and independent auditors, and (viii) to any actual or
proposed participant or assignee of all or part of its rights hereunder which
has agreed in writing to be bound by the provisions of this Section 12.07.

                  12.8 SURVIVAL. The obligations of the Company under
Sections 6.01, 6.05, 6.06, 6.08, 6.09, 12.03 and 12.04 hereof and of the
Canadian Borrower under such Sections and Section 3.8 of Annex A hereto and
the obligations of the Lenders under Section 11.05 shall survive the
repayment of the Loans and the termination of the Commitments.
