                  NOW THEREFORE, the parties hereto hereby agree as follows:

                    SECTION 1. DEFINITIONS AND INTERPRETATION

                  1.1 Defined Terms. As used in this Agreement, the following
         terms shall have the following meanings:

                  "ABR": for any day, a rate per annum (rounded upwards, if
         necessary, to the next 1/16 of 1%) equal to the greatest of (a) the
         Prime Rate in effect on such day, (b) the Base CD Rate in effect on
         such day plus 1% and (c) the Federal Funds Effective Rate in effect on
         such day plus 1/2 of 1%. For purposes hereof: "Prime Rate" shall mean
         the rate of interest per annum publicly announced from time to time by
         Chase as its prime rate in effect at its principal office in New York
         City (the Prime Rate not being intended to be the lowest rate of
         interest charged by Chase in connection with extensions of credit to
         debtors); "Base CD Rate" shall mean the sum of (a) the product of (i)
         the Three-Month Secondary CD Rate and (ii) a fraction, the numerator of
         which is one and the denominator of which is one minus the C/D Reserve
         Percentage and (b) the C/D Assessment Rate; "Three-Month Secondary CD
         Rate" shall mean, for any day, the secondary market rate for
         three-month certificates of deposit reported as being in effect on such
         day (or, if such day shall not be a Business Day, the next preceding
         Business Day) by the Board through the public information telephone
         line of the Federal Reserve Bank of New York (which rate will, under
         the current practices of the Board, be published in Federal Reserve
         Statistical Release H.15(519) during the week following such day), or,
         if such rate shall not be so reported on such day or such next
         preceding Business Day, the average of the secondary market quotations
         for three-month certificates of deposit of major money center banks in
         New York City received at approximately 10:00 A.M., New York City time,
         on such day (or, if such day shall not be a Business Day, on the next
         preceding Business Day) by the Administrative Agent from three New York
         City negotiable certificate of deposit dealers of recognized standing
         selected by it; and "Federal Funds Effective Rate" shall mean, for any
         day, the weighted average of the rates on overnight federal funds
         transactions with members of the Federal Reserve System arranged by
         federal funds brokers, as published on the next succeeding Business Day
         by the Federal Reserve Bank of New York, or, if such rate is not so
         published for any day which is a Business Day, the average of the
         quotations for the day of such transactions received by the
         Administrative Agent from three federal funds brokers of recognized
         standing selected by it. If for any reason the Administrative Agent
         shall have determined (which determination shall be conclusive absent
         manifest error) that it is unable to ascertain the Base CD Rate or the
         Federal Funds Effective Rate, or both, for any reason, including the
         inability or failure of the Administrative Agent to obtain sufficient
         quotations in accordance with the terms thereof, the ABR shall be
         determined without regard to clause (b) or (c), or both, of the first
         sentence of this definition, as 










                                       3

         appropriate, until the circumstances giving rise to such inability no
         longer exist. Any change in the ABR due to a change in the Prime Rate,
         the Three-Month Secondary CD Rate or the Federal Funds Effective Rate 
         shall be effective as of the opening of business on the effective day 
         of such change in the Prime Rate, the Three-Month Secondary CD Rate or
         the Federal Funds Effective Rate, respectively.

                  "ABR Loans":  Loans the rate of interest applicable to which 
         is based upon the ABR.

                  "Acceptance" and "B/A": a banker's acceptance or a depository
         bill within the meaning of the Depository Bills and Notes Act (Canada),
         in either case denominated in C$ issued by the Canadian Borrower and
         accepted and, if applicable, purchased by a Canadian Revolving Credit
         Lender in accordance with this Agreement.

                  "Acceptance Exposure":  at any time, the aggregate face amount
         of Canadian B/A Loans.

                  "Acceptance Reimbursement Obligations": the obligation of the
         Canadian Borrower to reimburse the Canadian Revolving Credit Lenders
         pursuant to subsections 2.3(h) and 2.3(i).

                  "Affiliate": as to any Person, any other Person (other than a
         Subsidiary) which, directly or indirectly, is in control of, is
         controlled by, or is under common control with, such Person. For
         purposes of this definition, "control" of a Person means the power,
         whether or not exercised, directly or indirectly, to direct or cause
         the direction of the management and policies of such Person, whether by
         contract or otherwise or through the direct or indirect ownership of
         10% (or, for purposes of subsection 10.6, 50%) or more of any class of

         imposed on or measured by income or receipts, that are imposed on

received by the Administrative Agent prior to 11:00 A.M., New York City time, 
(i) three Business Days prior to the requested Borrowing Date, if all or any 
part of the requested Revolving Credit Loans are to be initially Eurodollar

ABR Loans, $1,000,000 or a whole multiple thereof (or, if then Available
Revolving Credit Commitments are less than $1,000,000, such lesser amount) and
(y) in the case of Eurodollar Loans, $5,000,000 or a whole multiple of
$1,000,000 in excess thereof. Upon receipt of any such notice from the Company,
the Administrative Agent shall promptly notify each Revolving Credit Lender
thereof. Each Revolving Credit Lender will make the amount of its pro rata share
of each borrowing available to the Administrative Agent for the account of the
Company at the office of the Administrative Agent specified in subsection 10.2
prior to 12:00 Noon, New York City time, on the Borrowing Date requested by the
Company in funds immediately available to the Administrative Agent. Such
borrowing will then be made available to the Company by the Administrative Agent
crediting the account of the Company on the books of such office with the
aggregate of the amounts made available to the Administrative Agent by the
Revolving Credit Lenders and in like funds as received by the Administrative
Agent.

                   (b) The Canadian Borrower may borrow under the Canadian
Revolving Credit Commitments during the Commitment Period on any Business Day,
provided that the Canadian Borrower shall give the Canadian Administrative Agent
irrevocable notice (which notice must be received by the Canadian Administrative
Agent prior to 11:00 A.M., Toronto time, (i) three Business Days prior to the
requested Borrowing Date, if all or any part of the requested Canadian Revolving
Credit Loans are to be initially Eurodollar Loans, (ii) two Business Days prior

shall be in an amount equal to (w) in the case of Canadian Base Rate Loans,
$1,000,000 or a whole multiple thereof (or, if then Available Canadian Revolving
Credit Commitments are less than $1,000,000, such lesser amount), (x) in the
case of Canadian Prime Rate Loans, C$1,000,000 or a whole multiple thereof (or,
if the then Available Canadian Revolving Credit Commitments are less than

$5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if the then

lesser amount) and (z) in the case of Canadian B/A Loans, C$5,000,000 or a whole
multiple of C$1,000,000 in excess thereof (or, if the then Available Canadian
Revolving Credit Commitments are less than C$5,000,000, such lesser amount).
Upon receipt of any such notice from the Canadian Borrower, the Canadian
Administrative Agent shall promptly notify 








                                       34

each Canadian Revolving Credit Lender thereof. Each Canadian Revolving Credit 
Lender will make the amount of its pro rata share of each borrowing available 
to the Canadian Administrative Agent for the account of the Canadian Borrower 
at the office of the Canadian Administrative Agent specified in subsection 
10.2 prior to 12:00 Noon, Toronto time, on the Borrowing Date requested 
by the Canadian Borrower in funds immediately available to the Canadian 
Administrative Agent. Such borrowing will then be made available to the 
Canadian Borrower by the Canadian Administrative Agent crediting the 
account of the Canadian Borrower on the books of such office with the 
aggregate of the amounts made available to the Canadian Administrative Agent 
by the Canadian Revolving Credit Lenders and in like funds as received by
the Canadian Administrative Agent. Notwithstanding the foregoing, Canadian B/A
Loans shall be made in accordance with the provisions of subsection 2.3.

                   2.3 Canadian B/A Loans; Acceptances. (a) Subject to the terms
and conditions of this Agreement, the Canadian Borrower may request a Canadian
B/A Loan by presenting drafts for acceptance and purchase as B/As by the
Canadian Revolving Credit Lenders.

                   (b) No Contract Period with respect to a B/A shall extend
beyond the Termination Date.

                   (c) To facilitate availment of the Canadian B/A Loans, the
Canadian Borrower hereby appoints each Canadian Revolving Credit Lender as its
attorney to sign and endorse on its behalf, in handwriting or by facsimile or
mechanical signature as and when deemed necessary by such Canadian Revolving
Credit Lender, blank forms of B/As substantially in the form of Exhibit H. In
this respect, it is each Canadian Revolving Credit Lender's responsibility to
maintain an adequate supply of blank forms of B/As for acceptance under this
Agreement. The Canadian Borrower recognizes and agrees that all B/As signed
and/or endorsed on its behalf by a Canadian Revolving Credit Lender as required
hereunder shall bind the Canadian Borrower as fully and effectually as if signed
in the handwriting of and duly issued by the proper signing officers of the
Canadian Borrower. Each Canadian Revolving Credit Lender is hereby authorized to
issue such B/As endorsed in blank in such face amounts as may be determined by
such Canadian Revolving Credit Lender; provided that the aggregate amount
thereof is equal to the aggregate amount of B/As required by the Canadian
Borrower to be accepted and purchased by such Canadian Revolving Credit Lender.
No Canadian Revolving Credit Lender shall be liable for any damage, loss or
other claim arising by reason of any loss or improper use of any such instrument
except the gross negligence or wilful misconduct of the Canadian Revolving
Credit Lender or its officers, employees, agents or representatives. Each
Canadian Revolving Credit Lender shall maintain a record with respect to B/As
(a) received by it from the Canadian Administrative Agent in blank hereunder,
(b) voided by it for any reason, (c) accepted and purchased by it hereunder, and
(d) canceled at their respective maturities. Each Canadian Revolving Credit
Lender further agrees to retain such records in the manner and for the statutory
periods provided in the various provincial or federal statutes and regulations
which apply to such Canadian Revolving Credit Lender. Each Canadian Revolving
Credit Lender agrees to provide such records to the Canadian Borrower at the
Canadian Borrower's expense upon request. On request by or on behalf of the
Canadian Borrower, a Canadian Revolving Credit Lender shall cancel all forms of
B/A which have been pre-signed or pre-endorsed on behalf of the Canadian









                                       35

Borrower and which are held by the said Canadian Revolving Credit Lender and are
not required to be issued in accordance with the Canadian Borrower's irrevocable
notice.

                   (d) Drafts of the Canadian Borrower to be accepted as B/As
hereunder shall be signed as set forth in this subsection 2.3. Notwithstanding
that any Person whose signature appears on any B/A may no longer be an
authorized signatory for any of the Canadian Revolving Credit Lenders or the
Canadian Borrower at the date of issuance of a B/A, such signature shall
nevertheless be valid and sufficient for all purposes as if such authority had
remained in force at the time of such issuance and any such B/A so signed shall
be binding on the Canadian Borrower.

                   (e) Promptly following receipt of a notice of borrowing,
notice of rollover or notice of conversion by way of B/As, in accordance with
subsection 2.2(b), 2.3(h) or 2.3(k), as applicable, the Canadian Administrative
Agent shall so advise the Canadian Revolving Credit Lenders and shall advise
each Canadian Revolving Credit Lender of the aggregate face amount of the B/As
to be accepted by it and the applicable Contract Period (which shall be
identical for all Canadian Revolving Credit Lenders). The aggregate face amount
of the B/As to be accepted by a Canadian Revolving Credit Lender shall be an
integral multiple of C$100,000 and such face amount shall be in each Canadian
Revolving Credit Lender's Applicable Percentage of such Canadian B/A Loan;
provided, that the Canadian Administrative Agent may, in its sole discretion,
increase or reduce any Canadian Revolving Credit Lender's portion of such B/A to
the nearest C$100,000.

                   (f) Upon acceptance of a B/A by a Canadian Revolving Credit
Lender, such Canadian Revolving Credit Lender shall purchase, or arrange for a
resident of Canada under the Income Tax Act (Canada) to purchase, each B/A from
the Canadian Borrower at the Discount Rate for such Canadian Revolving Credit
Lender applicable to such B/A accepted by it and provide to the Canadian
Administrative Agent the Discount Proceeds for the account of the Canadian
Borrower. The Stamping Fee payable by such Canadian Borrower to a Canadian
Revolving Credit Lender under subsection 2.12 in respect of each B/A accepted by
such Canadian Revolving Credit Lender shall be set off against the Discount
Proceeds payable by the Canadian Revolving Credit Lender under this subsection
2.3.

                   (g) Each Canadian Revolving Credit Lender may at any time and
from time to time hold, sell, rediscount or otherwise dispose of any or all B/As
accepted and purchased by it.

                   (h) With respect to each Canadian B/A Loan which is
outstanding hereunder, at or before 11:00 a.m. (Toronto time) two Business Days
before the maturity date of such B/As, the Canadian Borrower shall notify the
Canadian Administrative Agent at the Canadian Administrative Agent's address set
forth in subsection 10.2 by irrevocable telephone notice, followed by a notice
of rollover on the same day, if the Canadian Borrower intends to issue B/As on
such maturity date to provide for the payment of such maturing B/As. If the
Canadian Borrower fails to notify the Canadian Administrative Agent of its
intention to issue B/As on such maturity date, the Canadian Borrower shall
provide on the maturity date of such B/As payment to the Canadian Administrative
Agent on behalf of the Canadian Revolving Credit Lenders of an amount equal to
the aggregate face amount of such B/As. If the Canadian Borrower fails to 









                                       36

make such payment, such maturing B/As shall be deemed to have been converted on
their maturity date into a Canadian Prime Rate Loan in an amount equal to the
face amount of such B/As.

                   (i) The Canadian Borrower waives presentment for payment and
any other defense to payment of any amounts due to a Canadian Revolving Credit
Lender in respect of a B/A accepted and purchased by it pursuant to this
Agreement which might exist solely by reason of such B/A being held, at the
maturity thereof, by such Canadian Revolving Credit Lender in its own right and
the Canadian Borrower agrees not to claim any days of grace if such Canadian
Revolving Credit Lender as holder sues the Canadian Borrower on the B/A for
payment of the amount payable by the Canadian Borrower thereunder. On the
specified maturity date of a B/A, or such earlier date as may be required or
permitted pursuant to the provisions of this Agreement, the Canadian Borrower
shall pay the Canadian Revolving Credit Lender that has accepted and purchased
such B/A the full face amount of such B/A and after such payment, the Canadian
Borrower shall have no further liability in respect of such B/A and such
Canadian Revolving Credit Lender shall be entitled to all benefits of, and be
responsible for all payments due to third parties under, such B/A.

                   (j) If any Event of Default shall occur and be continuing and
the Loans are accelerated pursuant to Section 8, the Canadian Borrower shall, on
the Business Day it receives notice from the Canadian Administrative Agent,
deposit in an account with the Canadian Administrative Agent for the benefit of
the Canadian Revolving Credit Lenders, an amount in cash equal to its Acceptance
Exposure as of such date. Such deposit shall be held by the Canadian
Administrative Agent as collateral for the payment and performance of the
Canadian Borrower Obligations. So long as such Event of Default is continuing,
the Canadian Administrative Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, over such account. Other than any
interest earned on the investment of such deposits in Cash Equivalents, which
investments shall be made at the option and sole discretion of the Canadian
Administrative Agent, such deposits shall not bear interest. Interest or
profits, if any, on such investments shall accumulate in such account. Moneys in
such account shall automatically be applied by the Canadian Administrative Agent
to reimburse the applicable Canadian Revolving Credit Lenders for Acceptance
Exposure and, if the maturity of the Loans has been accelerated, to satisfy the
Canadian Borrower Obligations. All remaining amounts on deposit shall be
returned to the Canadian Borrower within three Business Days after all Events of
Default have been cured or waived.

                   (k) The Canadian Borrower shall have the right at any time
upon irrevocable notice to the Canadian Administrative Agent not later than
11:00 A.M., Toronto time, two Business Days prior to conversion, to convert
Canadian Prime Rate Loans to Canadian B/A Loans, subject to the following
conditions:

                   (i) each conversion shall be made pro rata among the Canadian
          Revolving Credit Lenders in accordance with the respective principal
          amounts of the Canadian Prime Rate Loans comprising the converted
          Loans;









                                       37

                   (ii) if less than all of the outstanding principal amount of
          Canadian Prime Rate Loans shall be converted, the aggregate principal
          amount converted shall not be less than C$5,000,000;

                   (iii) each conversion shall be effected by each Canadian
          Revolving Credit Lender's converting the applicable principal amount
          of its applicable Canadian Prime Rate Loans into Canadian B/A Loans
          having Discount Proceeds equal to such principal amount, and accrued
          interest on any Prime Rate Loans being converted shall be paid by the
          Canadian Borrower at the time of conversion;

                   (iv) all Acceptances to be issued as a result of the
          conversion of the Canadian Prime Rate Loans shall be issued in
          accordance with the provisions of this subsection 2.3; and

                   (v) Canadian Prime Rate Loans may not be converted into
          Canadian B/A Loans if a Default or an Event of Default has occurred
          and is continuing and the Canadian Administrative Agent has determined
          that such conversion is not appropriate.

                   (l) At the option of the Canadian Borrower and any Canadian
Revolving Credit Lender, Acceptances under this Agreement to be accepted by such
Canadian Revolving Credit Lender may be issued in the form of depository bills
for deposit with The Canadian Depository for Securities Limited pursuant to the
Depository Bills and Notes Act (Canada). All depository bills so issued shall be
governed by the provisions of this subsection 2.3.

                   2.4 Reallocation. (a) The Borrowers may, from time to time
during the Commitment Period (but not more than once per calendar quarter),
temporarily reduce, in whole or in part, or increase, the Canadian Revolving
Credit Commitments by giving an irrevocable joint written notice (each, a
"Reallocation Notice") to the Canadian Administrative Agent and the
Administrative Agent at least ten (10) Business Days prior to the day (which day
shall be a Business Day) specified in such notice as the effective date for such
reduction or increase in the Canadian Revolving Credit Commitments, which day
shall (unless otherwise agreed by all of the Canadian Revolving Credit Lenders
in their sole discretion) be the first Business Day of the next following
calendar quarter (the "Reallocation Date"). Any reductions or increases in the
Canadian Revolving Credit Commitments shall take effect on the Reallocation
Date. Each reduction or increase in the Canadian Revolving Credit Commitments
shall result in an automatic corresponding increase or reduction in the
Revolving Credit Commitments; provided that (A) the amount of the Canadian
Revolving Credit Commitments shall not, at any time, (i) be reduced to an amount
that is less than the Total Canadian Revolving Extensions of Credit at such time
or (ii) exceed the Maximum Canadian Revolving Credit Commitments, and (B) the
amount of the Revolving Credit Commitments shall not, at any time, (i) be
reduced to an amount that is less than the Total Revolving Extensions of Credit
at such time or (ii) exceed the Total Commitments as of the Effective Date, as
the Total Commitments may, from time to time, be permanently reduced or canceled
in accordance with subsection 2.8 or 2.9 and (C) the sum of the Revolving Credit
Commitments and the Canadian Revolving Credit Commitments shall not, at any
time, exceed the Total Commitments as of the Effective Date, as the Total
Commitments may, from 









                                       38

time to time, be permanently reduced or canceled in accordance with subsection
2.8 or 2.9. Any amount of the Canadian Revolving Credit Commitments
reallocated under this subsection 2.4 as Revolving Credit Commitments
will not be available to the Canadian Borrower, and any amount of
the Revolving Credit Commitments reallocated under this subsection 2.4 as
Canadian Revolving Credit Commitments will not be available to the Company,
unless and until such amounts are reallocated back to the Canadian Revolving
Credit Commitments or the Revolving Credit Commitments, as the case may be, in
accordance with the terms and conditions of this subsection 2.4.

                   (b) The ability of the Borrowers to reallocate the Revolving
Credit Commitments and the Canadian Revolving Credit Commitments in accordance
with this subsubsection 2.4 shall be subject to the conditions that (A) the
representations and warranties set forth in each Loan Document shall be true and
correct in all material respects on and as of the date of such reallocation with
the same effect as though made on and as of such date, except to the extent that
such representations and warranties expressly relate to an earlier date and (B)
at the time of and immediately following such reduction or increase, no Event of
Default or Default shall have occurred and be continuing. Each Reallocation
Notice shall specify the amount (expressed in Dollars) of any reduction or
increase in the Canadian Revolving Credit Commitments and the corresponding
increase or reduction in the Revolving Credit Commitments. Each reallocation
requested under this subsection 2.4 shall be in a minimum aggregate principal
amount of $5,000,000 (or, if less, the remaining amount of the Total Canadian
Revolving Credit Commitments) and in integral multiples of $1,000,000. Each
reduction or increase in the Canadian Revolving Credit Commitments under this
subsection 2.4 shall be made ratably among the Canadian Revolving Credit Lenders
based on their respective Canadian Revolving Credit Commitments. Each reduction
or increase in the Revolving Credit Commitments under this subsection 2.4 shall
be made ratably among the Revolving Credit Lenders based on their respective
Revolving Credit Commitments. The Canadian Administrative Agent or the
Administrative Agent, as the case may be, shall promptly after receiving a
Reallocation Notice notify each Canadian Revolving Credit Lender or Revolving
Credit Lender, as the case may be, of the amount of its Canadian Revolving
Credit Commitment or Revolving Credit Commitment, as the case may be, to be
reallocated and the date of such reallocation.

                   2.5 Canadian Borrower. Notwithstanding anything in this
Agreement or in any other Loan Document to the contrary, wherever in this
Agreement or any other Loan Document a representation or warranty, indemnity,
covenant or other obligation is expressed to be given or made by or imposed upon
the Canadian Borrower, such representation, warranty, indemnity, covenant or
obligation shall in each case not impose on the Canadian Borrower any obligation
to give financial assistance by way of loan, guarantee, the giving of security,
the payment of money or otherwise within the meaning of Section 44 of the Canada
Business Corporations Act to or for the benefit of any person other than a
holding body corporate as referred to in clause 44(2)(c) of the Canada Business
Corporations Act.

                   2.6 Repayment of Loans; Evidence of Debt. (a) The Company
hereby unconditionally promises to pay to the Administrative Agent for the
account of the appropriate Revolving Credit Lender the then unpaid principal
amount of each Revolving Credit Loan of such Revolving Credit Lender on the
Termination Date (or such earlier date on which the Loans 








                                       39

become due and payable pursuant to Section 8 or the Revolving Credit 
Commitments are otherwise terminated). The Canadian Borrower hereby 
unconditionally promises to pay to the Canadian Administrative Agent 
for the account of the appropriate Canadian Revolving Credit Lender the 
then unpaid principal amount of each Canadian Revolving Credit Loan of 
such Canadian Revolving Credit Lender on the Termination Date (or 
such earlier date on which the Loans became due and payable pursuant 
to Section 8 or the Canadian Revolving Credit Commitments are otherwise
terminated). Each Borrower hereby further agrees to pay interest on the unpaid
principal amount of the Loans from time to time outstanding from the date hereof
until payment in full thereof at the rates per annum, and on the dates, set
forth in subsection 2.12.

                   (b) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing indebtedness of each Borrower to such
Lender resulting from each Loan of such Lender from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time under this Agreement.

                   (c) (i) The Administrative Agent, on behalf of the Company,
shall maintain the Register pursuant to subsection 10.6(d), and a subaccount
therein for each Lender, in which shall be recorded (A) the amount of each Loan
made hereunder and any Note evidencing such Loan, the Type thereof and each
Interest Period applicable thereto, (B) the amount of any principal or interest
due and payable or to become due and payable from the Company to each Lender
hereunder and (C) both the amount of any sum received by the Administrative
Agent hereunder from the Company and each Lender's share thereof.

                   (ii) The Canadian Administrative Agent, on behalf of the
Canadian Borrower, shall maintain the Register pursuant to subsection 10.6(d),
and a subaccount therein for each Canadian Revolving Credit Lender, in which
shall be recorded (A) the amount of each Canadian Revolving Credit Loan made
hereunder and any Note evidencing such Loan, the Type thereof and each Contract
Period (if any) applicable thereto, (B) the amount of any principal or interest
due and payable or to become due and payable from the Canadian Borrower to each
Canadian Revolving Credit Lender hereunder and (C) both the amount of any sum
received by the Canadian Administrative Agent hereunder from the Canadian
Borrower and each Canadian Revolving Credit Lender's share thereof.

                   (d) The entries made in the Register and the accounts of each
Lender maintained pursuant to subsection 2.6(b) shall, to the extent permitted
by applicable law and in the absence of manifest error, be prima facie evidence
of the existence and amounts of the obligations of each Borrower therein
recorded; provided, however, that the failure of any Lender, the Administrative
Agent or the Canadian Administrative Agent to maintain the Register or any such
account, or any error therein, shall not in any manner affect the obligation of
either Borrower to repay (with applicable interest) the Loans made to such
Borrower by such Lender in accordance with the terms of this Agreement.

                   (e) Each Borrower agrees that, upon the request to the
Applicable Agent by any Lender, such Borrower will execute and deliver to such
Lender a promissory note of such Borrower evidencing any Loans of such Lender,
substantially in the forms of Exhibit F-1 in the








                                       40

case of Revolving Credit Loans or F-2 in the case of Canadian Revolving
Credit Loans, with appropriate insertions as to date and principal amount.

                   2.7 Commitment Fee. (a) (i) Subject to subsection
2.15(b)(ii), the Company agrees to pay to the Administrative Agent for the
account of each Revolving Credit Lender a commitment fee in Dollars for the
period from and including the first day of the Commitment Period to the
Termination Date, computed at the Commitment Fee Rate on and after the Effective
Date, on the average daily amount of the Available Revolving Credit Commitment
of such Lender during the period for which payment is made, payable quarterly in
arrears on the last day of each March, June, September and December and on the
Termination Date or such earlier date as the Revolving Credit Commitments shall
terminate as provided herein, commencing on the first of such dates to occur
after the Effective Date.

                   (ii) Subject to subsection 2.15(b)(ii), the Canadian Borrower
agrees to pay to the Canadian Administrative Agent for the account of each
Canadian Revolving Credit Lender a commitment fee in Dollars for the period from
and including the first day of the Commitment Period to the Termination Date,
computed at the Commitment Fee Rate on and after the Effective Date, on the
average daily amount of the Available Canadian Revolving Credit Commitment of
such Lender during the period for which payment is made, payable quarterly in
arrears on the last day of each March, June, September and December and on the
Termination Date or such earlier date as the Canadian Revolving Credit
Commitments shall terminate as provided herein, commencing on the first of such
dates to occur after the Effective Date.

                   (b) The Company agrees to pay to the Agents the fees in the
amounts and on the dates from time to time agreed to in writing by Holdings or
the Company and the respective Agents.

                   2.8 Optional Termination or Reduction of Commitments . The
Company shall have the right, upon not less than five Business Days' notice to
the Administrative Agent, to terminate the Total Commitments or, from time to
time, to reduce the amount of the Total Commitments, provided that (i) in the
event of a partial reduction of the Total Commitments, such notice shall specify
how such reduction is to be applied to the Total Revolving Credit Commitments
and the Total Canadian Revolving Credit Commitments, and (ii) no such
termination or reduction shall be permitted if, after giving effect thereto and
to any prepayments of the Loans made on the effective date thereof, (A) the
aggregate principal amount of the Revolving Credit Loans then outstanding, when
added to the then outstanding L/C Obligations under the Revolving Credit
Commitments, would exceed the Revolving Credit Commitments then in effect or (B)
the Dollar Equivalent Amount of the aggregate principal amount of the Canadian
Revolving Credit Loans then outstanding, when added to the then outstanding L/C
Obligations under the Canadian Revolving Credit Commitments, would exceed the
Canadian Revolving Credit Commitments then in effect. Any such partial reduction
of the Total Commitments, the Total Revolving Credit Commitments and/or the
Total Canadian Revolving Credit Commitments shall be in an amount equal to
$1,000,000 or a whole multiple thereof and shall reduce permanently the Total
Commitments and, subject to any reallocation permitted under subsection 2.4, the
Revolving Credit Commitments or the Canadian Revolving Credit Commitments, as
applicable, then in effect.









                                       41

                   2.9 Optional Prepayments; Mandatory Prepayments and
Commitment Reductions. (a) Each Borrower may on the last day of any Interest
Period with respect thereto, in the case of Eurodollar Loans, on the last day of
any Contract Period with respect thereto, in the case of Canadian B/A Loans, or
at any time and from time to time, in the case of ABR Loans, Canadian Base Rate
Loans and Canadian Prime Rate Loans, prepay the Loans, in whole or in part,
without premium or penalty, upon at least three Business Days' irrevocable
notice in the case of Eurodollar Loans, upon at least two Business Days'
irrevocable notice in the case of Canadian B/A Loans, and upon at least one
Business Day's irrevocable notice in the case of ABR Loans, Canadian Base Rate
Loans and Canadian Prime Rate Loans, to the Applicable Agent, specifying the
date and amount of prepayment and whether the prepayment is of (i) Revolving
Credit Loans, Canadian Revolving Credit Loans or a combination thereof and (ii)
Eurodollar Loans, ABR Loans, Canadian B/A Loans, Canadian Base Rate Loans,
Canadian Prime Rate Loans or a combination thereof, and, if of a combination
thereof, the amount allocable to each. Upon receipt of any such notice the
Applicable Agent shall promptly notify each affected Lender thereof. If any such
notice is given, the amount specified in such notice shall be due and payable on
the date specified therein, together with any amounts payable pursuant to
subsection 2.19.

                   (b) (i) If, at any time during the Commitment Period, the
Total Revolving Extensions of Credit exceed the Total Revolving Credit
Commitments then in effect, the Company shall, without notice or demand,
immediately repay the Revolving Credit Loans in an aggregate principal amount
equal to such excess, together with interest accrued to the date of such payment
or prepayment and any amounts payable under subsection 2.19. To the extent that
after giving effect to any prepayment of the Revolving Credit Loans required by
the preceding sentence, the Total Revolving Extensions of Credit exceed the
Total Revolving Credit Commitments then in effect, the Company shall, without
notice or demand, immediately cash collateralize the then outstanding L/C
Obligations under the Revolving Credit Commitments in an amount equal to such
excess in accordance with paragraph (f) below.

                   (ii) If, at any time during the Commitment Period, the Total
Canadian Revolving Extensions of Credit exceed the aggregate Canadian Revolving
Credit Commitments then in effect, the Canadian Borrower shall, without notice
or demand, immediately repay the Canadian Revolving Credit Loans (other than
Canadian B/A Loans) in an aggregate principal amount equal to such excess,
together with interest accrued to the date of such payment or prepayment and any
amounts payable under subsection 2.19. To the extent that after giving effect to
any prepayment of the Canadian Revolving Credit Loans required by the preceding
sentence, the Total Canadian Revolving Extensions of Credit exceed the Total
Canadian Revolving Credit Commitments then in effect, the Canadian Borrower
shall, without notice or demand, immediately cash collateralize the then
outstanding L/C Obligations under the Canadian Revolving Credit Commitments and
Acceptance Exposure in an amount equal to such excess in accordance with
paragraph (f) below.

                   (c) If any Capital Stock or Indebtedness shall be issued or
incurred by the Company or any of its Subsidiaries (other than Indebtedness
permitted to be incurred under subsection 7.2 as in effect on the Closing Date,
including Indebtedness the proceeds of which are used to finance Permitted
Acquisitions), an amount equal to (i) in the case of issuances of Capital Stock,
50%, and (ii) in the case of incurrences of Indebtedness, 100%, of the Net Cash
Proceeds 








                                       42

thereof shall be applied on the date of such issuance or incurrence
toward the permanent reduction of the Total Commitments as set forth in
subsection 2.9(e).

                   (d) If on any date the Company or any of its Subsidiaries
shall receive Net Cash Proceeds from any Asset Sale or Recovery Event then (i)
unless a Reinvestment Notice shall be delivered in respect thereof, such Net
Cash Proceeds shall be applied on such date toward the permanent reduction of
the Total Commitments as set forth in subsection 2.9(e) or (ii) if a
Reinvestment Notice has been delivered in respect thereof, on each Reinvestment
Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with
respect to the relevant Reinvestment Event shall be applied toward the permanent
reduction of the Total Commitments as set forth in subsection 2.9(e).
Notwithstanding the foregoing, all Net Cash Proceeds in excess of $30,000,000
received in any fiscal year shall be applied toward the permanent reduction of
the Total Commitments as set forth in subsection 2.9(e).

                   (e) (i) Total Commitment reductions made pursuant to this
subsection 2.9 shall be applied to reduce the Total Revolving Credit Commitments
and the Total Canadian Revolving Credit Commitments in any order designated by
the Company, subject to any reallocation permitted under subsection 2.4.

                   (ii) Any such reduction of the Total Revolving Credit
Commitments shall be accompanied by prepayment of the Revolving Credit Loans to
the extent, if any, that the Total Revolving Extensions of Credit exceed the
amount of the Total Revolving Credit Commitments as so reduced, provided that if
the aggregate principal amount of Revolving Credit Loans then outstanding is
less than the amount of such excess (because L/C Obligations under the Revolving
Credit Commitments constitute a portion thereof), the Company shall, to the
extent of the balance of such excess, replace outstanding Letters of Credit
and/or deposit an amount in cash in a cash collateral account established with
the Administrative Agent for the benefit of the Lenders in accordance with
paragraph (f) below. The application of any prepayment pursuant to this
subsection shall be made first to ABR Loans and second to Eurodollar Loans. Each
prepayment of the Revolving Credit Loans under this subsection 2.9(e)(ii)
(except in the case of Revolving Credit Loans that are ABR Loans) shall be
accompanied by accrued interest to the date of such prepayment on the amount
prepaid and any amounts payable under subsection 2.19.

                   (iii) Any such reduction of the Total Canadian Revolving
Credit Commitments shall be accompanied by prepayment of the Canadian Revolving
Credit Loans (other than Canadian B/A Loans) to the extent, if any, that the
Total Canadian Revolving Extensions of Credit exceed the amount of the Total
Canadian Revolving Credit Commitments as so reduced, provided that if the
aggregate principal amount of Canadian Revolving Credit Loans (other than
Canadian B/A Loans) then outstanding is less than the amount of such excess
(because Canadian B/A Loans or L/C Obligations under the Canadian Revolving
Credit Commitments constitute a portion thereof), the Canadian Borrower shall,
to the extent of the balance of such excess, replace outstanding Letters of
Credit, terminate outstanding Acceptances and/or deposit an amount in cash in a
cash collateral account established with the Canadian Administrative Agent for
the benefit of the Canadian Revolving Credit Lenders in accordance with
paragraph (f) below. Each prepayment of the Loans under this subsection 2.9
(e)(iii) shall be accompanied by accrued 








                                       43

interest to the date of such prepayment on the amount prepaid and any amounts 
payable under subsection 2.19.

                   (f) The cash collateralization of L/C Obligations and
Acceptance Reimbursement Obligations shall be accomplished by the applicable
Borrower's depositing an amount equal to such L/C Obligations or Acceptance
Reimbursement Obligations, as the case may be, in a cash collateral account
opened by the Applicable Agent. This account shall bear interest which shall, so
long as no Event of Default has occurred and is continuing, be payable to the
applicable Borrower (and, if an Event of Default shall have occurred, such
interest shall remain in such account until such Event of Default ceases to
exist or the Applicable Agent has applied such interest to payment of the
Company Obligations or the Canadian Borrower Obligations, as the case may be).
Neither Borrower shall have any right to withdraw any amount from such cash
collateral account; provided that, so long as no Default or Event of Default has
occurred and is continuing or would result therefrom, the Applicable Agent
shall, at the request of the applicable Borrower, from time to time, release an
amount of cash collateral equal to the excess of all cash collateral then on
deposit in such cash collateral account over the then applicable outstanding L/C
Obligations and Acceptance Reimbursement Obligations and accrued interest
thereon. Each Borrower hereby grants to the Applicable Agent, for the benefit of
the applicable Issuing Banks and the applicable Participating Banks, a security
interest in such cash collateral (in whatever form) and the proceeds thereof to
secure all such L/C Obligations. Amounts held in such cash collateral account
shall be applied by the Applicable Agent to the payment of such L/C Obligations
and Acceptance Reimbursement Obligations. Each Borrower shall execute and
deliver to the Applicable Agent, for the account of the applicable Issuing Banks
and Participating Banks, such further documents and instruments as the
Applicable Agent may reasonably request to evidence the creation and perfection
of such security interest in such cash collateral account.

                   (g) If, on any Quarterly Date, the outstanding balance of the
Total Canadian Revolving Extensions of Credit exceeds 105% of the Canadian
Revolving Credit Commitments (as a result of the fluctuation of currency values
or otherwise), the Canadian Borrower shall immediately repay the aggregate
outstanding Canadian Revolving Credit Loans (other than Canadian B/A Loans) to
the extent required to eliminate such excess. If any such excess remains after
repayment in full of such Canadian Revolving Credit Loans, the Canadian Borrower
shall provide cash collateral for the L/C Obligations under the Canadian
Revolving Credit Commitments and Acceptance Exposure in the manner set forth in
subsections 2.3(j) and 2.10(f), as applicable, to the extent required to
eliminate such excess.

                   2.10 Conversion and Continuation Options. (a) Either Borrower
may elect from time to time to convert Eurodollar Loans to ABR Loans, in the
case of the Company, or Canadian Base Rate Loans, in the case of the Canadian
Borrower, by giving the Applicable Agent at least two Business Days' prior
irrevocable notice of such election, provided that any such conversion of
Eurodollar Loans may only be made on the last day of an Interest Period with
respect thereto. Either Borrower may elect from time to time to convert ABR
Loans, in the case of the Company, or Canadian Base Rate Loans, in the case of
the Canadian Borrower, to Eurodollar Loans by giving the Applicable Agent at
least three Business Days' prior irrevocable notice of such election. Any such
notice of conversion to Eurodollar Loans shall specify the 









                                       44

length of the initial Interest Period or Interest Periods therefor. Upon 
receipt of any such notice the Applicable Agent shall promptly notify 
each affected Lender thereof. All or any part of outstanding Eurodollar 
Loans and ABR Loans, in the case of the Company, or Canadian Base Rate Loans, 
in the case of the Canadian Borrower, may be converted as provided 
herein, provided that (i) no Loan may be converted into a Eurodollar Loan 
under a particular Facility when any Event of Default has occurred and is 
continuing and the Applicable Agent has or the Majority Facility Lenders 
under such Facility have determined not to permit such conversions and
(ii) no Loan under a particular Facility may be converted into a Eurodollar Loan
after the date that is one month prior to the final scheduled termination or
maturity date of such Facility.

                   (b) Any Eurodollar Loans may be continued as such upon the
expiration of then current Interest Period with respect thereto by the relevant
Borrower giving notice to the Applicable Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in subsection 1.1,
of the length of the next Interest Period to be applicable to such Loans,
provided that no Eurodollar Loan under a particular Facility may be continued as
such (i) when any Event of Default has occurred and is continuing and the
Applicable Agent has or the Majority Facility Lenders under such Facility have
determined not to permit such continuations or (ii) after the date that is one
month prior to the final scheduled termination or maturity date of such Facility
and provided, further, that if the relevant Borrower shall fail to give any
required notice as described above in this paragraph or if such continuation is
not permitted pursuant to the preceding proviso such Loans shall be
automatically converted to ABR Loans, in the case of the Company, or Canadian
Base Rate Loans, in the case of the Canadian Borrower, on the last day of such
then expiring Interest Period.

                   (c) Canadian B/A Loans and Canadian Prime Rate Loans may be
converted and continued as provided in subsection 2.3.

                   2.11 Minimum Amounts of Tranches. All borrowings, conversions
and continuations of Loans hereunder and all selections of Interest Periods and
Contract Periods hereunder shall be in such amounts and be made pursuant to such
elections so that, after giving effect thereto, the aggregate principal amount
of the Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or
a whole multiple of $1,000,000 in excess thereof and the aggregate amount of any
Canadian B/A Loans having identical Contract Periods commencing on the same date
shall be equal to C$5,000,000 or a whole multiple of C$1,000,000 in excess
thereof.

                   2.12 Interest Rates and Payment Dates. (a) Each Eurodollar
Loan shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

                   (b) Each ABR Loan shall bear interest at a rate per annum
equal to the ABR plus the Applicable Margin.

                   (c) Each Acceptance shall be subject to a Stamping Fee
payable on the date of acceptance thereof.









                                       45

                   (d) Each Canadian Base Rate Loan shall bear interest at a
rate per annum equal to the US Base Rate plus the Applicable Margin.

                   (e) Each Canadian Prime Rate Loan shall bear interest at a
rate per annum equal to the Canadian Prime Rate plus the Applicable Margin.

                   (f) If all or a portion of (i) the principal amount of any
Loan, (ii) any interest payable thereon or (iii) any commitment fee or other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum which is (x) in the case of overdue principal, the rate that
would otherwise be applicable thereto pursuant to the foregoing provisions of
this subsection plus 2% (or, in the case of overdue Acceptance Reimbursement
Obligations, the rate that would be applicable to Canadian Prime Rate Loans plus
2%) or (y), to the extent permitted by applicable law, in the case of overdue
interest, commitment fee or other amount due in Dollars, the rate described in
paragraph (b) or (d) of this subsection for the applicable Facility (or, if
there is no applicable Facility, for the Revolving Credit Facility) plus 2%, in
each case from the date of such non-payment until such amount is paid in full
(as well after as before judgment), or (z) to the extent permitted by applicable
law, in the case of overdue interest, commitment fee or other amount due in
Canadian Dollars, the rate described in paragraph (e) of this subsection plus
2%, in each case from the date of such non-payment until such amount is paid in
full (as well after as before judgment); provided that, for purposes of this
subsection 2.12(f), any amount secured by mortgages on real property, if
required by the Interest Act (Canada), shall bear interest at the same rate as
such principal or interest amount not in arrears.

                   (g) Interest shall be payable in arrears on each Interest
Payment Date, provided that interest accruing pursuant to paragraph (f) of this
subsection shall be payable from time to time on demand.

                   2.13 Computation of Interest and Fees. (a) Commitment fees,
commissions and interest shall be calculated on the basis of a 360-day year for
the actual days elapsed, except that, with respect to ABR Loans the rate of
interest on which is calculated on the basis of the Prime Rate, Canadian Prime
Rate Loans and Canadian Base Rate Loans, interest thereon shall be calculated on
the basis of a 365- (or 366-, as the case may be) day year for the actual days
elapsed. The Applicable Agent shall as soon as practicable notify the relevant
Borrower and the affected Lenders of each determination of a Eurodollar Rate.
Any change in the interest rate on a Loan resulting from a change in the ABR,
the Canadian Prime Rate, the US Base Rate or the Eurocurrency Reserve
Requirements shall become effective as of the opening of business on the day on
which such change becomes effective. The Applicable Agent shall as soon as
practicable notify the affected Borrower and the affected Lenders of the
effective date and the amount of each such change in interest rate.

                   (b) Each determination of an interest rate by the
Administrative Agent or the Canadian Administrative Agent pursuant to any
provision of this Agreement shall be conclusive and binding on the Borrowers and
the Lenders in the absence of manifest error. The Administrative Agent shall, at
the request of the Company, deliver to the Company a statement 








                                       46

showing the quotations used by the Administrative Agent in determining any 
interest rate pursuant to subsection 2.12(a).

                   (c) For purposes of the Interest Act (Canada), whenever any
interest under this Agreement is calculated using an annual rate based on a
period which is less than the actual number of days in a year (the "Lesser
Period"), such rate determined pursuant to such calculation, when expressed as
an annual rate, is equivalent to (i) the applicable rate based on such Lesser
Period, (ii) multiplied by the actual number of days in the calendar year in
which the period for which such interest is payable ends, and (iii) divided by
the number of days in such Lesser Period. The rates of interest specified in
this Agreement are nominal rates and all interest payments and computations are
to be made without allowance or deduction for deemed reinvestment of interest.

                   2.14 Inability to Determine Interest Rate. If prior to the
first day of any Interest Period:

                   (a) the Applicable Agent shall have determined (which
          determination shall be conclusive and binding upon the relevant
          Borrower) that, by reason of circumstances affecting the relevant
          market, adequate and reasonable means do not exist for ascertaining
          the Eurodollar Rate for such Interest Period, or

                   (b) the Applicable Agent shall have received notice from the
          Majority Facility Lenders in respect of the relevant Facility that the
          Eurodollar Rate determined or to be determined for such Interest
          Period will not adequately and fairly reflect the cost to such Lenders
          (as conclusively certified by such Lenders) of making or maintaining
          their affected Loans during such Interest Period,

the Applicable Agent shall give telecopy or telephonic notice thereof to the
relevant Borrower and the relevant Lenders as soon as practicable thereafter. If
such notice is given (x) any Eurodollar Loans under the relevant Facility
requested to be made on the first day of such Interest Period shall be made as
ABR Loans, (y) any Loans under the relevant Facility that were to have been
converted on the first day of such Interest Period to Eurodollar Loans under
such Facility shall be converted to or continued as ABR Loans, in the case of
the Company, or Canadian Base Rate Loans, in the case of the Canadian Borrower,
and (z) any outstanding Eurodollar Loans under such Facility shall be converted,
on the first day of such Interest Period, to ABR Loans, in the case of the
Company, or Canadian Base Rate Loans, in the case of the Canadian Borrower.
Until such notice has been withdrawn by the Applicable Agent, no further
Eurodollar Loans under such Facility shall be made or continued as such, nor
shall the relevant Borrower have the right to convert Loans under such Facility
to Eurodollar Loans.

                   2.15 Pro Rata Treatment and Payments. (a) Each borrowing by a
Borrower from the Lenders hereunder, each payment by a Borrower on account of
any commitment fee hereunder and any reduction of the Commitments of the Lenders
shall be made pro rata according to the respective Revolving Credit Commitment
Percentages or Canadian Revolving Credit Commitment Percentages, as the case may
be, of the relevant Lenders. Each payment 









                                       47

(other than prepayments) on account of principal of and interest on the Loans, 
each payment in respect of fees payable hereunder and each payment in respect 
of Reimbursement Obligations and Acceptance Reimbursement Obligations shall be 
applied to the amounts of such obligations owing to the Lenders pro rata 
according to the respective amounts then due and owing to the Lenders, 
except to the extent otherwise required by clause (ii) of subsection 
2.15(b), by subsection 2.18 or by subsection 2.21. All payments (including 
prepayments) to be made by the Company hereunder, whether on account of 
principal, interest, fees or otherwise, shall be made without set off
or counterclaim and shall be made prior to 12:00 Noon, New York City time, on
the due date thereof to the Administrative Agent, for the account of the
Lenders, at the Administrative Agent's office specified in subsection 10.2, in
Dollars and in immediately available funds, and all payments (including
prepayments) to be made by the Canadian Borrower hereunder, whether on account
of principal, interest, fees or otherwise, shall be made without setoff or
counterclaim and shall be made prior to 12:00 Noon, Toronto time, on the date
thereof to the Canadian Administrative Agent, for the account of the Lenders, at
the Canadian Administrative Agent's office specified in subsection 10.2, in
Dollars or Canadian Dollars, as required by the Loan Documents, and in
immediately available funds. Each of the Administrative Agent and the Canadian
Administrative Agent shall distribute such payments to the Lenders promptly upon
receipt in like funds as received. If any payment hereunder (other than payments
on the Eurodollar Loans) becomes due and payable on a day other than a Business
Day, such payment shall be extended to the next succeeding Business Day, and,
with respect to payments of principal, interest thereon shall be payable at then
applicable rate during such extension. If any payment on a Eurodollar Loan
becomes due and payable on a day other than a Business Day, the maturity thereof
shall be extended to the next succeeding Business Day unless the result of such
extension would be to extend such payment into another calendar month, in which
event such payment shall be made on the immediately preceding Business Day. In
the case of any extension of any payment of principal pursuant to the preceding
two sentences, interest thereon shall be payable at the then applicable rate
during such extension.

                   (b) Unless an Applicable Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to such
Applicable Agent, such applicable Agent may assume that such Lender is making
such amount available to such Applicable Agent, and such Applicable Agent may,
in reliance upon such assumption, make available to the applicable Borrower a
corresponding amount. If such amount is not made available to such Applicable
Agent by the required time on the Borrowing Date therefor, such Lender shall pay
to such Applicable Agent, on demand, such amount with interest thereon at a rate
equal to (i) in the case of amounts to be made available in Dollars, the daily
average Federal Funds Effective Rate for the period until such Lender makes such
amount immediately available to such Applicable Agent, and (ii) in the case of
amounts to be made available in Canadian Dollars, the Canadian Administrative
Agent's reasonable estimate of its average daily cost of funds. A certificate of
such Applicable Agent submitted to any Lender with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error. If
such Lender's share of such borrowing is not made available to such Applicable
Agent by such Lender (any such Lender, a "Non-Funding Lender") within three
Business Days of such Borrowing Date, (i) the Applicable Agent shall also be
entitled to recover such amount with interest thereon at the rate per annum
applicable to ABR Loans (in the case of amounts to be made available in Dollars)
or to Canadian 








                                       48

Prime Rate Loans (in the case of amounts to be made available in Canadian 
Dollars), on demand, from the applicable Borrower, (ii) the commitment
fee of such Non-Funding Lender referred to in subsection 2.7 shall not accrue
during the period commencing on such Borrowing Date and ending on the date on
which such Non-Funding Lender makes available to the Applicable Agent its share
of such borrowing and (iii) the Company shall have the right to replace such
Non-Funding Lender in accordance with subsection 2.21.

                   (c) Each obligation of the Loan Parties under the Loan
Documents related to any Loans or Letters of Credit denominated in Dollars
(including reimbursement obligations, interest, fees and commissions) shall be
paid in Dollars. Each obligation of the Loan Parties under the Loan Documents
related to any Loans or Letters of Credit denominated in Canadian Dollars
(including reimbursement obligations, interests, fees and commissions) shall be
paid in Canadian Dollars.

                   2.16 Illegality. (a) Notwithstanding any other provision
herein, if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof by any central bank or other Governmental
Authority shall make it unlawful for any Lender to make or maintain Eurodollar
Loans as contemplated by this Agreement (i) the commitment of such Lender
hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert ABR Loans, in the case of the Company, or Canadian Base Rate Loans, in
the case of the Canadian Borrower, to Eurodollar Loans shall forthwith be
canceled; provided that any request by the relevant Borrower pursuant to
subsection 2.2 or 2.10 for a Eurodollar Loan shall, as to such Lender, be deemed
to be a request for an ABR Loan, in the case of the Company, or a Canadian Base
Rate Loan, in the case of the Canadian Borrower, and (ii) such Lender's Loans
then outstanding as Eurodollar Loans, if any, shall be converted automatically
to ABR Loans, in the case of the Company, or Canadian Base Rate Loans, in the
case of the Canadian Borrower, on the respective last days of then current
Interest Periods with respect to such Loans or within such earlier period as
required by law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of then current Interest Period with respect thereto,
the relevant Borrower shall pay to such Lender such amounts, if any, as may be
required pursuant to subsection 2.19.

                   (b) Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or
application thereof by any central bank or other Governmental Authority shall
make it unlawful for any Lender to create or maintain Acceptances as
contemplated by this Agreement (i) the commitment of such Lender hereunder to
accept drafts, purchase Acceptances, continue Acceptances as such and convert
Canadian Prime Rate Loans to Acceptances shall forthwith be canceled and (ii)
the full face amount of such Lender's then outstanding Acceptances, if any,
shall be converted automatically to Canadian Prime Rate Loans on the respective
maturities thereof, or within such earlier period as required by law.

                   2.17 Requirements of Law. (a) If the adoption of or any
change in any Requirement of Law or in the interpretation or application thereof
by any central bank or other Governmental Authority or compliance by any Lender
with any request or directive (whether or 









                                       49

not having the force of law) from any central bank or other Governmental
Authority made subsequent to the date hereof (or, if later, the date on
which such Lender becomes a Lender):

                   (i) shall subject any Lender to any tax of any kind
          whatsoever with respect to this Agreement, any Letter of Credit, any
          Application or any Eurodollar Loan made by it, or change the basis of
          taxation of payments to such Lender in respect thereof (except for
          Non-Excluded Taxes and changes in the rate of net income taxes, branch
          profits taxes or franchise taxes imposed in lieu of net income taxes
          of such Lender);

                   (ii) shall impose, modify or hold applicable any reserve,
          special deposit, compulsory loan or similar requirement against assets
          held by, deposits or other liabilities in or for the account of,
          advances, loans or other extensions of credit by, or any other
          acquisition of funds by, any office of such Lender which is not
          otherwise included in the determination of the Eurodollar Rate; or

                   (iii) shall impose on such Lender any other condition
          (excluding any tax of any kind whatsoever);

and the result of any of the foregoing is to increase the cost to such Lender,
by an amount which such Lender reasonably deems to be material, of making,
converting into, continuing or maintaining Eurodollar Loans or issuing or
participating in Letters of Credit or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the relevant Borrower shall promptly
pay such Lender, within 15 days after receipt by such Borrower of a certificate
referred to in the second succeeding sentence, any additional amounts necessary
to compensate such Lender for such increased cost or reduced amount receivable.
If any Lender becomes entitled to claim any additional amounts pursuant to this
subsection, it shall promptly notify the relevant Borrower, through the
Applicable Agent, of the event by reason of which it has become so entitled. A
certificate as to any additional amounts payable pursuant to this subsection
(setting forth in reasonable detail the calculation of such amounts) submitted
by such Lender, through the Applicable Agent, to the relevant Borrower shall be
conclusive in the absence of manifest error. This covenant shall survive for one
hundred eighty (180) days after the termination of this Agreement and the
payment of the Loans and all other amounts payable hereunder.

                   (b) If any Lender shall have determined that the adoption of
or any change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof by any Governmental Authority or
compliance by such Lender or any corporation controlling such Lender with any
request, guideline or directive regarding capital adequacy (whether or not
having the force of law) from any Governmental Authority made subsequent to the
date hereof (or, if later, the date on which such Lender becomes a Lender) does
or shall have the effect of reducing the rate of return on such Lender's or such
corporation's capital as a consequence of its obligations hereunder or under any
Letter of Credit to a level below that which such Lender or such corporation
could have achieved but for such change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount reasonably deemed by such Lender to be material, then from time to
time, after 








                                       50

submission by such Lender to the applicable Borrower (with a copy to the 
Applicable Agent) of a written request therefor (setting forth in reasonable
detail the calculation of amounts to be paid hereunder as a result thereof),
such Borrower shall pay to such Lender such additional amount or amounts as will
compensate such Lender for such reduction.

                   2.18 Taxes. (a) All payments made by the Borrowers 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 or branch profits taxes or franchise taxes
imposed in lieu of net income taxes imposed on any Agent or any Lender as a
result of a present or former connection between such Agent or such Lender and
the jurisdiction of the Governmental Authority imposing such tax or any
political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from such 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") are required to be withheld from any amounts payable to any Agent or any
Lender hereunder, the amounts so payable to such Agent or such Lender shall be
increased to the extent necessary to yield to such Agent or such Lender (after
payment of all Non-Excluded Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement and the
Notes, provided, however, that the Borrowers shall be entitled to deduct and
withhold any Non-Excluded Taxes and neither Borrower shall not be required to
increase any such amounts payable to any Revolving Credit Lender that fails to
comply with the requirements of paragraph (b) of this subsection. Each Lender
shall promptly notify the Company of a change in such Lender's tax status that
would require a Borrower to withhold and/or pay any amounts under this paragraph
(a). Whenever any Non-Excluded Taxes are payable by a Borrower, as promptly as
possible thereafter such Borrower shall send to the Applicable Agent for its own
account or for the account of such Agent or Lender, as the case may be, a
certified copy of an original official receipt received by such Borrower showing
payment thereof. If a Borrower fails to pay any Non-Excluded Taxes when due to
the appropriate taxing authority or fails to remit to the Applicable Agent the
required receipts or other required documentary evidence within 30 days of
written request therefor by any Agent or such Lender and the date such receipt
or evidence first becomes available to such Borrower, such Borrower shall
indemnify the Agents and the Lenders for any incremental taxes, interest or
penalties that may become payable by any Agent or any Lender as a result of any
such failure. The agreements in this subsection shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder.

                   (b) Each Revolving Credit Lender that is not a United States
person as defined in Section 7701(a)(30) of the Code shall:

                   (X) (1) before the first payment date after it becomes a
          party to this Agreement deliver to the Company and the Administrative
          Agent two duly completed copies of (A) Internal Revenue Service Form
          W-8BEN, in the case of a Lender claiming treaty benefits with respect
          to payments under this Agreement and any Notes, or Internal 









                                       51

          Revenue Service Form W-8ECI, in the case of a Lender claiming 
          payments under this Agreement and any Notes are effectively 
          connected with the conduct of a trade or business within the 
          United States, or successor applicable form, as the case may 
          be, and covering all amounts receivable by it under this Agreement 
          and any Notes, together with such other forms, documentation 
          or certifications as may be necessary to establish an available 
          exemption from deduction or withholding of U.S. federal income 
          taxes with respect to payments under this Agreement and any Notes;

                   (ii) deliver to the Company and the Administrative Agent two
          further copies of any such form or certification on or before the date
          that any such form, documentation or certification expires or becomes
          obsolete and after the occurrence of any event requiring a change in
          the most recent form previously delivered by it to the Company; and

                   (iii) obtain such extensions of time for filing and file such
          forms, documentation or certifications as may reasonably be requested
          by the Company or the Administrative Agent; and

                   (Y) in the case of any such Lender that is not a "bank"
          within the meaning of Section 881(c)(3)(A) of the Code and that cannot
          comply with the requirements of subsection 2.18(b)(X) above, (i)
          represent to the Company (for the benefit of the Company and the
          Agents) that it is not a bank within the meaning of Section
          881(c)(3)(A) of the Code, (ii) agree to furnish to the Company on or
          before the date of any payment by the Company, with a copy to the
          Administrative Agent, (A) a certificate substantially in the form of
          Exhibit H (any such certificate a "U.S. Tax Compliance Certificate")
          and (B) two accurate and complete original signed copies of Internal
          Revenue Service Form W-8BEN, or successor applicable form certifying
          to such Lender's legal entitlement at the date of such certificate to
          an exemption from U.S. withholding tax under the provisions of Section
          871(h) or 881(c) of the Code with respect to payments to be made under
          this Agreement and any Notes (and to deliver to the Company and the
          Administrative Agent two further copies of such form on or before the
          date it expires or becomes obsolete and after the occurrence of any
          event requiring a change in the most recently provided form, and, if
          necessary, obtain any extensions of time reasonably requested by the
          Company or the Administrative Agent for filing and completing such
          forms), and (iii) agree, to the extent legally entitled to do so, upon
          reasonable request by the Company, to provide to the Company (for the
          benefit of the Company and the Agents) such other forms, documentation
          or certification as may be reasonably required in order to establish
          the legal entitlement of such Lender to an exemption from withholding
          with respect to payments under this Agreement and any Notes;

unless in any such case any change in treaty, law or regulation has occurred
after the date on which such Lender becomes a Lender under this Agreement 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 so
advises the Company and the Administrative Agent. Such Lender shall certify (i)
in the case of a Lender claiming treaty benefits with respect 









                                       52

payments under this Agreement and any Notes, or in the case of a Lender claiming
amounts receivable by it under this Agreement any Notes are effectively
connected with the conduct of a trade or business within the United States, that
it is entitled to receive payments under this Agreement and any Notes without
deduction or withholding of any United States federal income taxes and (ii) that
it is entitled to an exemption from United States backup withholding tax. Each
Person that shall become a Lender or a Participant pursuant to subsection 10.6
shall, upon the effectiveness of the related transfer, be required to provide
all of the forms, documentation and certifications required pursuant to this
subsection, provided that in the case of a Participant such Participant shall
furnish all such required forms, documentation and certifications to the Lender
from which the related participation shall have been purchased, and such Lender
shall in turn furnish all such required forms, documentation and certifications
to the Borrowers and the Administrative Agent, together with such other forms
(including, without limitation, Internal Revenue Service Form W-8IMY),
documentation or certifications as may be necessary to establish an available
exemption from deduction or withholding of U.S. federal income taxes on payments
under this Agreement and any Notes.

                   (c) If any Lender, the Administrative Agent or the Canadian
Administrative Agent shall become aware in its sole and good faith judgment that
it is entitled to receive a refund in respect of Non-Excluded Taxes as to which
it has received additional amounts from either Borrower pursuant to subsection
2.18(a), it shall promptly notify such Borrower of the availability of such
refund and within 30 days after receipt of a request by such Borrower, apply for
such refund at such Borrower's expense. If any Lender, the Administrative Agent
or the Canadian Administrative Agent receives a refund in respect of 
Non-Excluded Taxes as to which it has received additional amounts from either
Borrower pursuant to subsection 2.18(a), it shall promply repay such refund to
such Borrower, provided, however, that if any Lender, the Administrative Agent
or the Canadian Administrative Agent receives a refund which it must
subsequently return to the applicable taxing authority after such Borrower has
already been repaid, such Borrower agrees to promptly return the amount of such
repayment to the Lender, the Administrative Agent or the Canadian Administrative
Agent.

                   (d) For the purposes of this subsection 2.18 and subsection
2.17, a change in treaty, law, rule or regulation shall not include (i) the
ratification or entry into force of the income tax treaty between the United
States and Luxembourg or (ii) the new United States withholding regulations
(Treasury Decision 8734 and Treasury Decision 8804) which become effective on
January 1, 2000.

                   2.19 Indemnity. Each Borrower agrees to indemnify each Lender
and to hold each Lender harmless from any reasonably foreseeable loss or expense
which such Lender may sustain or incur caused by (a) default by such Borrower in
making a borrowing of, conversion into or continuation of Eurodollar Loans after
such Borrower has given a notice requesting the same in accordance with the
provisions of this Agreement, (b) default by such Borrower in making any
prepayment after such Borrower has given a notice thereof in accordance with the
provisions of this Agreement or (c) the making of a payment or prepayment of
Eurodollar Loans on a day which is not the last day of an Interest Period with
respect thereto. Such indemnification shall include an amount equal to the
excess, if any, of (i) the amount of interest 









                                       53

which would have accrued on the amount so prepaid, or not so borrowed, converted
or continued, for the period from the date of such prepayment or of such failure
to borrow, convert or continue to the last day of such Interest Period (or, in
the case of a failure to borrow, convert or continue, the Interest Period that
would have commenced on the date of such failure) in each case at the applicable
rate of interest for such Loans provided for herein (excluding, however, the
Applicable Margin included therein, if any) over (ii) the amount of interest (as
reasonably determined by such Lender) which would have accrued to such Lender on
such amount by placing such amount on deposit for a comparable period with
leading banks in the interbank eurodollar market. This covenant shall survive
the termination of this Agreement and the payment of the Loans and all other
amounts payable hereunder.

                   2.20 Change of Lending Office. Each Lender agrees that, upon
the occurrence of any event giving rise to the operation of Section 2.17 or
2.18(a) with respect to such Lender, it will, if requested by a Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event, including avoiding the need
for, or reducing the amounts of, additional costs of the Borrower pursuant to
subsection 2.17 or 2.18(a); provided, that such designation is made on terms
that, in the sole judgment of such Lender, cause such Lender and its lending
office(s) to suffer no economic, legal or regulatory disadvantage, and provided,
further, that nothing in this subsection shall affect or postpone any of the
obligations of either Borrower or the rights of any Lender pursuant to
subsection 2.17 or 2.18(a).

                   2.21 Replacement of Lenders under Certain Circumstances. Each
Borrower shall be permitted to replace any Lender (a) which requests
reimbursement for amounts owing pursuant to Section 2.17 or 2.18, (b) which
defaults in its obligation to make Loans or create Acceptances hereunder or (c)
if such Lender or its affiliated Allocation Lender shall be unable, for any
reason, to permit the Borrowers to effect a reallocation in accordance with
subsection 2.4; provided that (i) such replacement does not conflict with any
Requirement of Law, (ii) no Event of Default shall have occurred and be
continuing at the time of such replacement, (iii) prior to any such replacement,
such Lender shall not have designated a different lending office under
subsection 2.20 so as to eliminate the continued need for payment of amounts
owing pursuant to Section 2.17 or 2.18, (iv) the replacement financial
institution shall purchase, at par, all Loans and other amounts owing to such
replaced Lender on or prior to the date of replacement, (v) such Borrower shall
be liable to such replaced Lender under subsection 2.19 if any Eurodollar Loan
owing to such replaced Lender shall be purchased other than on the last day of
the Interest Period relating thereto, (vi) if the Lender to be replaced has an
Acceptance Exposure and is to be replaced on any day other than the last day of
the applicable Contract Period, such Borrower shall cash collateralize such
Acceptance Exposure in a manner acceptable to such Lender, (vii) the replacement
financial institution, if not already a Lender, shall be reasonably satisfactory
to the Administrative Agent, (viii) the replaced Lender shall be obligated to
make such replacement in accordance with the provisions of subsection 10.6
(provided that such Borrower shall be obligated to pay the registration and
processing fee referred to therein), (ix) until such time as such replacement
shall be consummated, such Borrower shall pay all additional amounts (if any)
required pursuant to subsection 2.17 or 2.18, as the case may be, (x) any such
replacement shall not be deemed to be a waiver of any rights which the
Borrowers, the Administrative Agent, the











                                       54


Canadian Administrative Agent or any other Lender shall have against the
replaced Lender and (xi) any Lender may be replaced only if its affiliated
Allocation Lender also is replaced in accordance with this subsection 2.21, and
any replacement financial institution in respect of such Allocation Lender shall
assume, or such financial institution together with its Affiliate shall assume
on a pro rata basis, each of the Commitments of such replaced Allocation
Lenders.




                          SECTION 3. LETTERS OF CREDIT

                   3.1. L/C Commitment. (a) Subject to the terms and conditions
hereof, each Issuing Bank, in reliance on the agreements of the Lenders set
forth in subsection 3.4(a), agrees to issue letters of credit ("Letters of
Credit") for the account of a Borrower on any Business Day during the Commitment
Period in such form as may be approved from time to time by such Issuing Bank
and the Applicable Agent; provided that no Issuing Bank shall have any
obligation to issue any Letter of Credit if, after giving effect to such
issuance, (i) the sum of the L/C Obligations under the Revolving Credit
Commitments and the L/C Obligations under the Canadian Revolving Credit
Commitments would exceed the L/C Commitment, (ii) the aggregate Available
Revolving Credit Commitments would be less than zero or (iii) the aggregate
Available Canadian Revolving Credit Commitments would be less than zero.

                   (b) Letters of Credit issued for the account of the Company
shall be issued under the Revolving Credit Commitments, and Letters of Credit
issued for the account of the Canadian Borrower shall be issued under the
Canadian Revolving Credit Commitments. Each Letter of Credit issued under the
Revolving Credit Commitments shall be denominated in Dollars and each Letter of
Credit issued under the Canadian Revolving Credit Commitments shall be
denominated in Dollars or Canadian Dollars. Each Letter of Credit shall expire
no later than the earlier of (i) 365 days after its date of issuance and (ii)
five Business Days prior to the Termination Date, provided that any Letter of
Credit with a one-year term may provide for an annual renewal (which shall in no
event extend beyond the date referred to in clause (ii) above) if such renewal
is consented to by the applicable Issuing Bank and all conditions precedent to
the issuance of Letters of Credit are met at the time of such renewal.

                   (c) Each Letter of Credit shall be subject to the Uniform
Customs and, to the extent not inconsistent therewith, (i) if such Letter of
Credit is issued under the Revolving Credit Commitments, the laws of the State
of New York and (ii) if such Letter of Credit is issued under the Canadian
Revolving Credit Commitments, the laws of the Province of Ontario.

                   (d) No Issuing Bank shall at any time be obligated to issue
any Letter of Credit hereunder if such issuance would conflict with, or cause
such Issuing Bank or any Participating Bank to exceed any limits imposed by, any
applicable Requirement of Law.

                   (e) The letters of credit listed on Schedule IV shall be
deemed to be Letters of Credit issued under this Agreement on the Closing Date.









                                       55

                   3.2. Procedure for Issuance of Letters of Credit. A Borrower
may from time to time request that an Issuing Bank issue a Letter of Credit by
delivering to such Issuing Bank (with a copy to the Applicable Agent) at its
address for notices specified herein an Application therefor, completed to the
satisfaction of such Issuing Bank and such Applicable Agent, and such other
certificates, documents and other papers and information as such Issuing Bank
may reasonably request. Upon receipt of any Application, such Issuing Bank will
process such Application and the certificates, documents and other papers and
information delivered to it in connection therewith in accordance with its
customary procedures and shall promptly issue the Letter of Credit requested
thereby (but in no event shall an Issuing Bank be required to issue any Letter
of Credit earlier than three Business Days after its receipt of the Application
therefor and all such other certificates, documents and other papers and
information relating thereto) by issuing the original of such Letter of Credit
to the beneficiary thereof or as otherwise may be agreed by such Issuing Bank
and the applicable Borrower. The Issuing Bank shall furnish a copy of such
Letter of Credit to the applicable Borrower and to each applicable Participating
Bank promptly following the issuance thereof.

                   3.3. Fees, Commissions and Other Charges. (a) Each Borrower
will pay a fee on all outstanding Letters of Credit issued for the account of
such Borrower at a per annum rate equal to the Applicable Margin then in effect
with respect to Eurodollar Loans under the Revolving Credit Facility, shared
ratably among the Revolving Credit Lenders or Canadian Revolving Credit Lenders,
as the case may be, and payable quarterly in arrears on each L/C Fee Payment
Date after the issuance date. In addition, each Borrower shall pay to the
applicable Issuing Lender for its own account a fronting fee on all outstanding
Letters of Credit issued for the account of such Borrower of 1/8 of 1% per
annum, payable quarterly in arrears on each L/C Fee Payment Date after the
Issuance Date.

                   (b) In addition to the foregoing fees and commissions, each
Borrower shall pay or reimburse each Issuing Bank for such normal and customary
costs and expenses as are incurred or charged by such Issuing Bank in issuing,
effecting payment under, amending or otherwise administering any Letter of
Credit issued for the account of such Borrower; provided that such costs and
expenses are not paid by such Borrower under subsections 2.19, 3.5 and/or 10.5
of this Agreement.

                   3.4. L/C Participations. (a) Each Issuing Bank irrevocably
agrees to grant and hereby grants to each applicable Participating Bank, and, to
induce the Issuing Banks to issue Letters of Credit hereunder, each
Participating Bank irrevocably agrees to accept and purchase and hereby accepts
and purchases from each applicable Issuing Bank, on the terms and conditions
hereinafter stated, for such Participating Bank's own account and risk an
undivided interest equal to such Participating Bank's Applicable Percentage in
the relevant Issuing Bank's obligations and rights under each Letter of Credit
issued by it hereunder in accordance with the terms hereof and the amount of
each draft paid by such Issuing Bank thereunder. Each Participating Bank
unconditionally and irrevocably agrees with each applicable Issuing Bank that,
if a draft is paid under any Letter of Credit for which such Issuing Bank is not
reimbursed in full by the applicable Borrower in accordance with the terms of
this Agreement, such Participating Bank shall pay to such Issuing Bank upon
demand at such Issuing Bank's address









                                       56


for notices specified herein an amount equal to such Participating Bank's
Applicable Percentage of the amount of such draft, or any part thereof, which is
not so reimbursed.

                   (b) If any amount required to be paid by any Participating
Bank to an Issuing Bank pursuant to paragraph in respect of any unreimbursed
portion of any payment made by such Issuing Bank under any Letter of Credit is
paid to such Issuing Bank after the date such payment is due, such Participating
Bank shall pay to such Issuing Bank on demand an amount equal to the product of
(i) such amount, times (ii) (a) the daily average Federal funds rate, as quoted
by such Issuing Bank, with respect to Letters of Credit issued under the
Revolving Credit Commitments and (b) the average daily cost of funds as quoted
by such Issuing Bank with respect to Letters of Credit issued under the Canadian
Revolving Credit Commitments, in each case during the period from and including
the date such payment is required to the date on which such payment is
immediately available to such Issuing Bank, times (iii) a fraction the numerator
of which is the number of days that elapse during such period and the
denominator of which is 360. A certificate of an Issuing Bank submitted to
any Participating Bank with respect to any amounts owing under this subsection
shall be conclusive in the absence of manifest error.

                   (c) Whenever, at any time after an Issuing Bank has made
payment under any Letter of Credit and has received from any Participating Bank
its pro rata share of such payment in accordance with subsection 3.4(a), such
Issuing Bank receives any payment related to such Letter of Credit (whether
directly from the Borrowers or otherwise, including proceeds of collateral
applied thereto by such Issuing Bank), or any payment of interest on account
thereof, such Issuing Bank will distribute to such Participating Bank its pro
rata share thereof; provided, however, that in the event that any such payment
received by an Issuing Bank shall be required to be returned by such Issuing
Bank, such Participating Bank shall return to such Issuing Bank the portion
thereof previously distributed by such Issuing Bank to it.

                   3.5. Reimbursement Obligation of the Borrowers. (a) Each
Borrower agrees to reimburse each Issuing Bank which has issued a Letter of
Credit for the account of such Borrower on each date on which such Issuing Bank
notifies such Borrower of the date and amount of a draft presented under any
Letter of Credit and paid by such Issuing Bank for the amount of such draft so
paid and any stamp taxes, fees, charges or other costs or expenses incurred by
such Issuing Bank in connection with such payment. Each such payment shall be
made to such Issuing Bank at its address for notices specified herein in lawful
money of the United States of America or of Canada, as the case may be, and in
immediately available funds.

                   (b) Subject to paragraph (c) immediately below, interest
shall be payable on any and all amounts remaining unpaid by the applicable
Borrower under this Section from the date such amounts become payable (whether
at stated maturity, by acceleration or otherwise) until payment in full at the
rate which would be payable on any outstanding (i) ABR Loans under the Revolving
Credit Facility which were then overdue in the case of Letters of Credit
denominated in Dollars and issued under the Revolving Credit Facility, (ii)
Canadian Prime Rate Loans under the Canadian Revolving Credit Facility which are
then overdue in the case of Letters of Credit denominated in Canadian Dollars
and (iii) Canadian Base Rate Loans under the Canadian Revolving Credit Facility
which are then overdue in the case of Letters of Credit denominated in Dollars
and issued under the Canadian Revolving Credit Facility.









                                       57

                   (c) So long as each of the conditions precedent specified in
subsection 5.3 is satisfied at such time, each drawing under any Letter of
Credit shall constitute a request by the applicable Borrower to the Applicable
Agent for a borrowing pursuant to subsection 2.2 of ABR Loans under the
Revolving Credit Facility or Canadian Prime Rate Loans or Canadian Base Rate
Loans under the Canadian Revolving Credit Facility, as the case may be, in an
amount equal to the lesser of (i) the then aggregate Available Revolving Credit
Commitments or the Available Canadian Revolving Credit Commitments, as the case
may be, and (ii) the amount of such drawing. The Borrowing Date with respect to
such borrowing shall be the date of such drawing. Each Revolving Credit Lender
or Canadian Revolving Credit Lender, as the case may be, will make the amount of
its pro rata share of such borrowing available to the Applicable Agent at its
office specified in subsection 10.2 by the close of business on such Borrowing
Date (if such Lender receives notice of such borrowing in sufficient time to
fund its portion of such borrowing on such Date, and otherwise on the next
Business Day) in funds immediately available to the Applicable Agent. Such funds
will then be made available by the Applicable Agent to the relevant Issuing Bank
in satisfaction of the applicable Borrower's obligation to reimburse such
Issuing Bank pursuant to clause (a) above. All ABR Loans deemed to be made
pursuant to this paragraph (c) shall constitute Revolving Credit Loans for all
purposes of this Agreement, and all Canadian Prime Rate Loans and Canadian Base
Rate Loans deemed made pursuant to this paragraph (c) shall constitute Canadian
Revolving Credit Loans for all purposes of this Agreement.

                   3.6. Obligations Absolute. (a) Each Borrower's obligations
under this Section 3 shall be absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Borrowers may have or have had against any Issuing Bank or any
beneficiary of a Letter of Credit.

                   (b) Each Borrower also agrees with each Issuing Bank that
such Issuing Bank shall not be responsible for, and such Borrower's
Reimbursement Obligations under subsection 3.5(a) shall not be affected by,
among other things, (i) the validity or genuineness of documents or of any
endorsements thereon, even though such documents shall in fact prove to be
invalid, fraudulent or forged, or (ii) any dispute between or among the
Borrowers and any beneficiary of any Letter of Credit or any other party
to which such Letter of Credit may be transferred or any (iii) claims
whatsoever of either Borrower against any beneficiary of such Letter of
Credit or any such transferee.

                   (c) No Issuing Bank shall be liable for any error, omission,
interruption or delay in transmission, dispatch or delivery of any message or
advice, however transmitted, in connection with any Letter of Credit, except for
errors or omissions caused by the Issuing Bank's gross negligence or willful
misconduct.

                   (d) Each Borrower agrees that any action taken or omitted by
an Issuing Bank under or in connection with any Letter of Credit or the related
drafts or documents, if done in the absence of gross negligence or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial Code of the State of New York (in the case of Letters of Credit
Issued under the Revolving Credit Facility) or the Uniform Customs, as published
from time to time by the International Chamber of Commerce (in the case of
Letters of Credit Issued 









                                       58

under the Canadian Revolving Credit Facility), shall be binding on such Borrower
and shall not result in any liability of such Issuing Bank to such Borrower.

                   3.7. Letter of Credit Payments. If any draft shall be
presented for payment under any Letter of Credit, the relevant Issuing Bank
shall promptly notify the applicable Borrower of the date and amount thereof.
The responsibility of any Issuing Bank to such Borrower in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in such Letter of Credit, be limited
to determining that the documents (including each draft) delivered under such
Letter of Credit in connection with such presentment are in conformity with the
requirements of such Letter of Credit.

                   3.8. Application. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

                  To induce the Agents and the Lenders to enter into this
Agreement and to make the Loans and issue or participate in the Letters of
Credit, each Borrower hereby represents and warrants to the Agents and each
Lender that:

                   4.1 Financial Condition. (a) The combined balance sheets of
the Industrial Chemicals Business as at December 31, 1998 and December 31, 1997
and the combined statements of operations, changes in equity (deficit) and cash
flows for the fiscal years ended on December 31, 1998, December 31, 1997 and
December 31, 1996, reported on by Deloitte & Touche LLP, copies of which have
heretofore been furnished to each Lender, present fairly in all material
respects the consolidated financial condition of the Industrial Chemicals
Business as at such dates, and the consolidated results of its operations and
its changes in equity (deficit) and consolidated cash flows for the fiscal years
then ended.

                   (b) The combined pro forma balance sheet of the Industrial
Chemicals Business as of December 31, 1998 (the "Company Pro Forma Balance
Sheet"), certified by a Responsible Officer, a copy of which has heretofore been
furnished to each Lender, presents fairly in all material respects the combined
financial condition of the Industrial Chemicals Business as of December 31, 1998
after giving effect to the Spin-Off Transactions.

                   (c) The unaudited consolidated balance sheets of the Canadian
Borrower and its consolidated Subsidiaries as at December 31, 1998 and December
31, 1997 and the consolidated statements of operations, changes in equity
(deficit) and cash flows for the fiscal years ended on December 31, 1998 and
December 31, 1997, copies of which have heretofore been furnished to each
Lender, present fairly in all material respects the consolidated financial
condition of the Canadian Borrower and its consolidated Subsidiaries as at such
dates, and the consolidated results of their operations and their changes in
equity (deficit) and consolidated cash flows for the fiscal years then ended.









                                       59

                   (d) All financial statements referred to in the preceding
paragraphs (a), (b) and (c), including the related schedules and notes thereto,
have been prepared in accordance with GAAP applied consistently throughout the
periods involved (except as approved by such accountants or Responsible Officer,
as the case may be, and as disclosed therein and, in the case of unaudited
financial statements, except for the absence of footnotes thereto). Neither the
Company nor any of its consolidated Subsidiaries had, at the date of the Company
Pro Forma Balance Sheet and after giving effect to the Spin-Off Transactions,
any material Guarantee Obligation, contingent liability or liability for taxes,
or any long-term lease or unusual forward or long-term commitment, including,
without limitation, any interest rate or foreign currency swap or exchange
transaction, except as reflected in the Company Pro Forma Balance Sheet or in
the notes thereto. Except as disclosed in the 1998 10-K, the Confidential
Information Memorandum or the Form 10 Filing during the period from December 31,
1998 to and including the date hereof there has been no sale, transfer or other
disposition by the Company or any of its consolidated Subsidiaries of any
material part of its business or property and no purchase or other acquisition
of any business or property (including any capital stock of any other Person)
material in relation to the consolidated financial condition of the Company and
its consolidated Subsidiaries at December 31, 1998.

                   4.2 No Change. Since December 31, 1998 there has been no
development or event which has had or could reasonably be expected to have a
Material Adverse Effect.

                   4.3 Corporate Existence; Compliance with Law. Each of the
Company and its Subsidiaries (other than any non-Domestic Subsidiary which is
not a Material Foreign Subsidiary) (a) is duly organized, validly existing and,
if applicable, in good standing under the laws of the jurisdiction of its
organization, (b) has the power and authority, and the legal right, to own and
operate its property, to lease the property it operates as lessee and to conduct
the business in which it is currently engaged, (c) is duly qualified as a
foreign corporation, if applicable, and, if applicable, in good standing under
the laws of each jurisdiction where its ownership, lease or operation of
property or the conduct of its business requires such qualification except to
the extent that the failure to be so qualified and in good standing could not,
in the aggregate, reasonably be expected to have a Material Adverse Effect and
(d) is in compliance with all Requirements of Law except to the extent that the
failure to comply therewith could not, in the aggregate, reasonably be expected
to have a Material Adverse Effect.

                   4.4 Corporate Power; Authorization; Enforceable Obligations.
Each Loan Party has the power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and (in the case
of each Borrower) to borrow hereunder and have the Letters of Credit issued for
its account and has taken all necessary action (in the case of each Borrower) to
authorize the borrowings and the issuance of the Letters of Credit for its
account on the terms and conditions of this Agreement and the Applications and
(in the case of each Loan Party) to authorize the execution, delivery and
performance of the Loan Documents to which it is a party. No consent or
authorization of, filing with, notice to or other act by or in respect of, any
Governmental Authority or any other Person is required in connection with the
borrowings hereunder or with the execution, delivery, performance, validity or
enforceability of the Loan Documents. This Agreement has been, and each other
Loan Document will be, duly executed and delivered on behalf of the Loan Parties
party thereto. This Agreement constitutes, 








                                       60

and each other Loan Document when executed and delivered will constitute, a
legal, valid and binding obligation of the Loan Parties party thereto
enforceable against such Loan Parties in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

                   4.5 No Legal Bar. (a) The execution, delivery and performance
of the Loan Documents, the borrowings hereunder and the use of the proceeds
thereof, after giving effect to the Spin-Off Transactions, will not violate any
Requirement of Law or material Contractual Obligation of the Company or of any
of its Subsidiaries and will not result in, or require, the creation or
imposition of any Lien on any of its or their respective properties or revenues
pursuant to any such Requirement of Law or Contractual Obligation, other than
any violations or Liens that, individually or in the aggregate, could not
reasonably be expected to have a Material Adverse Effect.

                   (b) As of the Closing Date (i) all governmental and
third-party approvals necessary or advisable in connection with the Spin-Off
Transactions, the financing contemplated in connection therewith and the
continuing operations of the Company and its Subsidiaries have been obtained,
other than any approvals that, if not obtained, individually or in the
aggregate, could not reasonably be expected to have a Material Adverse Effect,
and (ii) all applicable waiting periods have expired without any action being
taken or threatened by any competent authority which would restrain, prevent or
otherwise impose adverse conditions on the Spin-Off Transactions or the
financing thereof. 

                   4.6 No Material Litigation. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or,
to the knowledge of the Borrowers, threatened by or against the Company or any
of its Subsidiaries or against any of its or their respective properties or
revenues (a) with respect to any of the Loan Documents or any of the
transactions contemplated hereby or (b) which could reasonably be expected to
have a Material Adverse Effect.

                   4.7 No Default. Neither the Company nor any of its
Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect which could reasonably be expected to have a Material
Adverse Effect. No Default or Event of Default has occurred and is continuing.

                   4.8 Ownership of Property; Liens. Each of the Company and its
Subsidiaries has (or upon the consummation of the Spin-Off Transactions will
have) good record and insurable title (and, with respect to real property
located in Canada, good and marketable title) in fee simple to, or a valid
leasehold interest in, all its material real property, and good title to, or a
valid leasehold interest in, all its other material property, and none of their
respective property is subject to any Lien except as permitted by subsection
7.3.









                                       61

                   4.9 Intellectual Property. The Company and each of its
Subsidiaries owns, or is licensed to use, all trademarks, tradenames,
copyrights, technology, know-how and processes necessary for the conduct of its
business as currently conducted except for those the failure to own or license
which could not reasonably be expected to have a Material Adverse Effect (the
"Intellectual Property"). No claim has been asserted and is pending by any
Person challenging or questioning the use of any such Intellectual Property or
the validity or effectiveness of any such Intellectual Property, nor do the
Borrowers know of any valid basis for any such claim, in each case, other than
those claims which, individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect. The use of such Intellectual
Property by the Borrowers and their Subsidiaries does not infringe on the rights
of any Person, except for such claims and infringements that, in the aggregate,
could not reasonably be expected to have a Material Adverse Effect.

                   4.10 Taxes. Each of the Company and its Subsidiaries has
filed or caused to be filed all U.S. federal income tax returns and all other
material tax returns which, to the knowledge of the Company, are required to be
filed and has paid all taxes shown to be due and payable on said returns or on
any assessments made against it or any of its property and all other taxes, fees
or other charges imposed on it or any of its property by any Governmental
Authority (other than those not yet delinquent, those with respect to which the
failure to pay could not reasonably be expected to have a Material Adverse
Effect and those the amount or validity of which are currently being contested
in good faith by appropriate proceedings diligently conducted and with respect
to which reserves in conformity with GAAP have been provided on the books of the
Company or its Subsidiaries, as the case may be); no tax Lien has been filed or
registered, and, to the knowledge of the Company, no claim is being asserted,
with respect to any such tax, fee or other charge.

                   4.11 Federal Regulations. No part of the proceeds of any
Loans will be used for "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U or for any
purpose which violates the provisions of the Regulations of the Board. If
requested by any Lender or the Administrative Agent, each Borrower will furnish
to the Administrative Agent and each Lender a statement to the foregoing effect
in conformity with the requirements of FR Form U-1 referred to in Regulation U.

                   4.12 ERISA; Canadian Benefit and Pension Plans. Other than
the Reportable Events resulting from the Spin-Off Transactions, neither a
Reportable Event nor an "accumulated funding deficiency" (within the meaning of
Section 412 of the Code or Section 302 of ERISA) has occurred and is continuing
on the date on which this representation is made or deemed made with respect to
any Single Employer Plan, and each Plan has complied in all material respects
with the applicable provisions of ERISA and the Code. No termination of a Single
Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has
arisen and remains in effect against the assets of the Company or any Commonly
Controlled Entity, as of each date on which this representation is made or
deemed made. The present value of all accrued benefits under each Single
Employer Plan (based on those assumptions used to fund such Plans) did not, as
of the last annual valuation date prior to the date on which this representation
is made or deemed made, exceed the value of the assets of such Plan allocable to
such accrued benefits by an 








                                       62

amount in excess of $19,000,000. Neither the Company nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan, and
neither the Company nor any Commonly Controlled Entity would become subject to
any liability under ERISA if the Company or any such Commonly Controlled Entity
were to withdraw completely from all Multiemployer Plans as of the valuation
date most closely preceding the date on which this representation is made or
deemed made. No such Multiemployer Plan is in Reorganization or Insolvent.
Notwithstanding the foregoing, there shall be no breach of the representations
set forth in this subsection 4.12 unless the amount of any liability of the
Company or any Commonly Controlled Entity which arises or which could reasonably
be expected to arise in connection with the matters giving rise to such breach,
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect

                   (b) Schedule V sets forth, as of the Closing Date, all
Canadian Benefit Plans (other than, for greater certainty, universal plans
created by and to which the Borrowers and their respective Subsidiaries are
obligated to contribute by statute) and Canadian Pension Plans adopted by the
Borrowers and their respective Subsidiaries. The Canadian Pension Plans are duly
registered under the Income Tax Act (Canada) and all other applicable laws which
require registration and no event has occurred which is reasonably likely to
cause the loss of such registered status. All material obligations of the
Borrowers and their respective Subsidiaries (including fiduciary, funding,
investment and administration obligations) required to be performed in
connection with the Canadian Pension Plans and the funding agreements therefor
have been performed in a timely fashion. There have been no improper withdrawals
or applications of the assets of the Canadian Pension Plans or the Canadian
Benefit Plans. There are no outstanding disputes concerning the assets of the
Canadian Pension Plans or the Canadian Benefit Plans which could reasonably be
expected to have a Material Adverse Effect. On a solvency basis (using actuarial
methods and assumptions which are consistent with the valuations last filed with
the applicable Governmental Authorities and which are consistent with generally
accepted actuarial principles), none of the Canadian Pension Plans is
under-funded by more than $8,000,000.

                   4.13 Investment Company Act; Other Regulations. Neither
Borrower is an "investment company", or a company "controlled" by an "investment
company", within the meaning of the Investment Company Act of 1940, as amended.
Neither Borrower is subject to regulation under any Federal or State statute or
regulation which limits its ability to incur Indebtedness.

                   4.14 Subsidiaries. Schedule II sets forth all the
Subsidiaries of the Company as of the Closing Date.

                   4.15 Purpose of Loans. The proceeds of the Loans and Letters
of Credit shall be used by each Borrower for working capital and general
corporate purposes of such Borrower, including financing Permitted Acquisitions
and Permitted Investments (and refinancing existing indebtedness in connection
with the Spin-Off Transactions).

                   4.16 Environmental Matters. To the best knowledge of the
Borrowers, the facilities and properties owned, leased or operated by the
Company or any of its Subsidiaries (the 









                                       63

 "Properties") do not contain any Hazardous Materials in amounts or
 concentrations which constitute or constituted a violation of any Environmental
 Law except in either case insofar as such violations in the aggregate could not
 reasonably be expected to have a Material Adverse Effect.

                   (b) To the best knowledge of the Borrowers, the Properties
and all operations at the Properties are in compliance with all applicable
Environmental Laws except for instances of noncompliance that individually or in
the aggregate could not reasonably be expected to have a Material Adverse
Effect, and there is no contamination at, under or about the Properties nor any
violation of any Environmental Law with respect to the Properties or the
business operated by the Company or any of its Subsidiaries (the "Business")
which in the aggregate could reasonably be expected to have a Material Adverse
Effect.

                   (c) Neither the Company nor any of its Subsidiaries has
received any written notice of violation, alleged violation, non-compliance,
liability or potential liability regarding environmental matters or compliance
with Environmental Laws with regard to any of the Properties or the Business,
nor do the Borrowers have knowledge that any such notice will be received or is
being threatened except insofar as such notice or threatened notice, or any
aggregation thereof, does not involve a matter or matters that could reasonably
be expected to have a Material Adverse Effect.

                   (d) To the best knowledge of the Borrowers, no Hazardous
Materials have been transported or disposed of from the Properties in violation
of any Environmental Law, nor have any Hazardous Materials been generated,
treated, stored or disposed of at, on or under any of the Properties in
violation of any applicable Environmental Law except insofar as any such
violation or liability referred to in this paragraph, or any aggregation
thereof, could not reasonably be expected to have a Material Adverse Effect.

                   (e) No judicial proceeding or governmental or administrative
action is pending or, to the knowledge of the Borrowers, threatened, under any
Environmental Law to which the Company or any Subsidiary is or will be named as
a party with respect to the Properties or the Business, nor are there any
consent decrees or other decrees, consent orders, administrative orders or other
orders, or other administrative or judicial requirements outstanding under any
Environmental Law with respect to the Properties or the Business except insofar
as such proceeding, action, decree, order or other requirement, or any
aggregation thereof, could not reasonably be expected to have a Material Adverse
Effect.

                   (f) To the best knowledge of the Borrowers, there has been no
release or threat of release of Hazardous Materials at or from the Properties,
or arising from or related to the operations of the Company or any Subsidiary in
connection with the Properties or otherwise in connection with the Business, in
violation of or in amounts or in a manner that could reasonably give rise to
liability under Environmental Laws except insofar as any such violation or
liability referred to in this paragraph, or any aggregation thereof, could not
reasonably be expected to have a Material Adverse Effect.










                                       64

                   4.17. Soda Ash Partners. Except as set forth in the Soda Ash
Partnership Agreement and the Soda Ash Parent Agreement, there are no
outstanding subscriptions, warrants, calls, options, rights (including
unsatisfied preemptive rights), commitments or agreements by which the Company
or any of its Subsidiaries, including Soda Ash Partners, is bound that permit or
entitle any Person to purchase or otherwise receive from or to be issued any
partnership interest in Soda Ash Partners or any security or obligation of any
kind convertible into any shares of partnership capital of Soda Ash Partners,
nor is Soda Ash Partners subject to any obligation (contingent or otherwise) to
repurchase or otherwise acquire or retire any shares of its partnership capital.

                   4.18 Solvency. Each Borrower, individually and together with
its Subsidiaries, is Solvent.

                   4.19 Labor Matters. There are no strikes or other labor
disputes against the Company or any of its Subsidiaries pending or, to the
knowledge of the Borrowers, threatened that in the aggregate could reasonably be
expected to have a Material Adverse Effect. Hours worked by and payment made to
employees of the Company and its Subsidiaries have not been in violation of the
Fair Labor Standards Act or any other applicable Requirement of Law dealing with
such matters that in the aggregate could reasonably be expected to have a
Material Adverse Effect. All payments due from the Company or any of its
Subsidiaries on account of employee income taxes (including source deductions),
employment insurance, workers safety and insurance, employers' health tax,
vaction pay, employee health and welfare insurance and other social security or
statutory obligations that in the aggregate could reasonably be expected to have
a Material Adverse Effect if not paid have been paid or accrued as a liability
on the books of the Company or the relevant Subsidiary, and to the extent
required by GAAP.

                   4.20 Accuracy of Information, etc. None of this Agreement,
any other Loan Document, the Confidential Information Memorandum, the Form 10
Filing or any other document, certificate, information or statement furnished to
the Administrative Agent, the Canadian Administrative Agent or the Lenders or
any of them, by or on behalf of any Loan Party for use in connection with the
transactions contemplated by this Agreement or the other Loan Documents,
contained as of the date such statement, information, document or certificate
was so furnished (or, in the case of the Confidential Information Memorandum, as
of the date of this Agreement), any untrue statement of a material fact or, all
such material taken as a whole, omitted to state a material fact necessary in
order to make the statements contained herein or therein not misleading. The
projections and pro forma financial information contained in the materials
referenced above are based upon good faith estimates and assumptions believed by
management of the Company to be reasonable at the time made, it being recognized
by the Lenders that such financial information as it relates to future events is
not to be viewed as fact and that actual results during the period or periods
covered by such financial information may differ from the projected results set
forth therein by a material amount. There is no fact known to the Company that
could reasonably be expected to have a Material Adverse Effect that has not been
expressly disclosed herein, in the other Loan Documents, in the Confidential
Information Memorandum, the Form 10 Filing or in any other documents,
certificates and statements furnished to the Administrative Agent and the
Lenders for use in connection with the transactions contemplated hereby and by
the other Loan Documents.









                                       65

                   4.21 Security Documents. (a) The Guarantee and Collateral
Agreement is effective to create in favor of the Administrative Agent, for the
benefit of the Lenders, a legal, valid and enforceable security interest (or
hypothec, if applicable) in the Collateral described therein (other than the
Collateral described in subsection 3.2(l) thereof) and proceeds thereof. In the
case of the Pledged Stock described in the Guarantee and Collateral Agreement,
when stock certificates representing such Pledged Stock are delivered to the
Administrative Agent, and in the case of the other Collateral described in the
Guarantee and Collateral Agreement, when financing statements in appropriate
form are filed in the offices specified in the Guarantee and Collateral
Agreement, the Guarantee and Collateral Agreement shall constitute a fully
perfected Lien on, and security interest in, all right, title and interest of
the Loan Parties in such Collateral and the proceeds thereof, as security for
the Company Obligations (as defined in the Guarantee and Collateral Agreement),
in each case prior and superior in right to any other Person (except, in the
case of Collateral other than Pledged Stock, Liens permitted by subsection 7.3).

                   (b) Each of the Canadian Security Documents is effective to
create in favor of the Canadian Administrative Agent, for the benefit of the
Canadian Revolving Credit Lenders, a legal, valid and enforceable security
interest (or hypothec, if applicable) in the Collateral described therein and
proceeds thereof. Upon completion of the actions set forth in each Canadian
Security Document, such Canadian Security Document, shall constitute a fully
perfected Lien on, and security interest in, all right, title and interest of
the Loan Parties in such Collateral and the proceeds thereof, as security for

                                       94

          commenced against the Company, NHO Canada, Canadian Holdings, the
          Canadian Borrower or any of the Company's Material Subsidiaries any
          case, proceeding or other action of a nature referred to in clause (i)
          above which (A) results in the entry of an order for relief or any
          such adjudication or appointment or (B) remains undismissed,
          undischarged or unbonded for a period of 60 days; or (iii) there shall
          be commenced against the Company, NHO Canada, Canadian Holdings, the
          Canadian Borrower or any of the Company's Material Subsidiaries any
          case, proceeding or other action seeking issuance of a warrant of
          attachment, execution, distraint or similar process against all or any
          substantial part of its assets which results in the entry of an order
          for any such relief which shall not have been vacated, discharged, or
          stayed or bonded pending appeal within 60 days from the entry thereof;
          or (iv) the Company, NHO Canada, Canadian Holdings, the Canadian
          Borrower or any of the Company's Material Subsidiaries shall take any
          action in furtherance of, or indicating its consent to, approval of,
          or acquiescence in, any of the acts set forth in clause (i), (ii), or
          (iii) above; or (v) the Company, NHO Canada, Canadian Holdings, the
          Canadian Borrower or any of the Company's Material Subsidiaries shall
          generally not, or shall be unable to, or shall admit in writing its
          inability to, pay its debts as they become due;

then, and in any such event:

                  (A) if such event is an Event of Default specified in clause
(i) or (ii) of paragraph (m) of this subsection 8.1 with respect to either
Borrower, automatically the Revolving Credit Commitments and the Canadian
Revolving Credit Commitments shall immediately terminate and the Loans hereunder
(with accrued interest thereon) and all other amounts owing under this Agreement
(including, without limitation, all amounts of L/C Obligations, whether or not
the beneficiaries of the then outstanding Letters of Credit shall have presented
the documents required thereunder, and all face amounts of Acceptances not drawn
upon, expired, demanded or matured, in accordance with subsection 2.3(j)) shall
immediately become due and payable; and

                   (B) if such event is any other Event of Default specified in

the consent of the Required Lenders, the Administrative Agent and/or the
Canadian Administrative Agent may, or upon the request of the Required Lenders,
the Administrative Agent and/or the Canadian Administrative Agent shall, by
notice to the Borrowers declare the Revolving Credit Commitments and the
Canadian Revolving Credit Commitments to be terminated forthwith, whereupon the
Revolving Credit Commitments and the Canadian Revolving Credit Commitments shall
immediately terminate and (ii) with the consent of the Required Lenders, the
Administrative Agent and/or the Canadian Administrative Agent may, or upon the
request of the Required Lenders, the Administrative Agent and/or the Canadian
Administrative Agent shall, by notice to the Borrowers, declare the Loans

thereof under this Agreement and the other Loan Documents (including, without
limitation, all amounts of L/C Obligations, whether or not the beneficiaries of
the then outstanding Letters of Credit shall have presented the documents
required thereunder, and all face amounts of Acceptances not drawn upon,
expired, demanded or matured, in accordance with subsection 2.3(j)) to be due
and payable forthwith, whereupon the same shall immediately become due and
payable.









                                       95

                   8.2 Certain Provisions Applicable to Letters of Credit. With
respect to all Letters of Credit issued from the account of a Borrower with
respect to which presentment for honor shall not have occurred at the time of an
acceleration pursuant to subsection 8.1, such Borrower shall at such time
deposit in a cash collateral account opened by the Applicable Agent an amount
equal to the aggregate then undrawn and unexpired amount of such Letters of
Credit. Each Borrower hereby grants to each Applicable Agent, for the benefit of
the applicable Issuing Banks and the applicable Participating Banks, a security
interest in such cash collateral to secure all obligations of such Borrower in
respect of such Letters of Credit under this Agreement and the other Loan
Documents. Amounts held in such cash collateral account shall be applied by the
Applicable Agent to the payment of drafts drawn under such Letters of Credit,
and the unused portion thereof after all such Letters of Credit shall have
expired or been fully drawn upon, if any, shall be applied to repay other
obligations of such Borrower hereunder and under the Notes. After all such
Letters of Credit shall have expired or been fully drawn upon, all Reimbursement
Obligations shall have been satisfied and all other obligations of the Borrowers
hereunder and under the Notes shall have been paid in full, the balance, if any,
in such cash collateral account shall be returned to the applicable Borrower.
Each Borrower shall execute and deliver to the Applicable Agent, for the account
of the applicable Issuing Banks and the applicable Participating Banks, such
further documents and instruments as the Applicable Agent may request to
evidence the creation and perfection of such security interest in such cash
collateral account.

                   8.3 Certain Waivers. Except as expressly provided above in
this Section, presentment, demand, protest and all other notices of any kind
with respect to matters set forth in this Section are hereby expressly waived.

                              SECTION 9. THE AGENTS

                   9.1 Appointment. Each Lender hereby irrevocably designates
and appoints Chase as the Administrative Agent of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes Chase, as the Administrative Agent for such Lender, to take such
action on its behalf under the provisions of this Agreement and the other Loan
Documents and to exercise such powers and perform such duties as are expressly
delegated to the Administrative Agent by the terms of this Agreement and the
other Loan Documents, together with such other powers as are reasonably
incidental thereto. Notwithstanding any provision to the contrary elsewhere in
this Agreement, the Administrative Agent shall not have any duties or
responsibilities, except those expressly set forth herein and in the other Loan
Documents, or any fiduciary relationship with any Lender, and no implied
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into this Agreement or any other Loan Document or otherwise exist
against the Administrative Agent. The Designated Issuer in its capacity as such
shall be entitled to the same rights under this Section 9 as accrue to the
Administrative Agent as if it were named in place of the Administrative Agent.
In acting as Collateral Agent Chase shall be entitled to the rights and benefits
of, and subject to the obligations set forth for, the Administrative Agent in
this Section 9, mutatis mutandis, which Section is hereby incorporated by
reference, mutatis mutandis, in each of the Security Documents.
                                       









                                       96

                   9.2 Delegation of Duties. The Administrative Agent may
execute any of its duties under this Agreement and the other Loan Documents by
or through agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties. The Administrative
Agent shall not be responsible for the negligence or misconduct of any agents or
attorneys in-fact selected by it with reasonable care.

                   9.3 Exculpatory Provisions. Neither the Administrative Agent
nor any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to any of the Lenders for
any recitals, statements, representations or warranties made by the Borrowers or
any officer thereof contained in this Agreement or any other Loan Document or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or the Notes or any
other Loan Document or for any failure of either Borrower to perform its
obligations hereunder or thereunder. The Administrative Agent shall not be under
any obligation to any Lender to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of either Borrower.

                   9.4 Reliance by Administrative Agent. The Administrative
Agent shall be entitled to rely, and shall be fully protected in relying, upon
any Note, writing, resolution, notice, consent, certificate, affidavit, letter,
telecopy, telex or teletype message, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to the Borrowers),
independent accountants and other experts selected by the Administrative Agent.
The Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders as it deems
appropriate or it shall first be indemnified to its satisfaction by the Required
Lenders as it deems appropriate against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
The Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the Notes and the other Loan
Documents if acting in accordance with a request of the Required Lenders as it
deems appropriate, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Lenders and all future holders of
the Notes.

                   9.5 Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless the Administrative Agent has received notice from a
Lender or the Company referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice











                                       97

of default". In the event that the Administrative Agent receives such a notice,
the Administrative Agent shall promptly give notice thereof to the Lenders.
The Administrative Agent shall take such action with respect to such Default
or Event of Default, or any acceleration of any amounts due hereunder, as
shall be reasonably directed by the Required 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 respect to such Default, Event of
Default or acceleration as it shall deem advisable in the best interests of
the relevant Lenders. To the extent that, as a result of the exercise by it
of any remedies with respect to any Collateral, the Administrative Agent shall
receive or realize any amounts, it shall distribute such amounts ratably among
the Lenders by reference to the aggregate amounts accrued and unpaid that are
outstanding under the Agreement and the other Loan Documents and owing to the
respective Lenders (after deducting and applying any amounts then owing to the
Administrative Agent or on account of expenses of the Administrative Agent
previously paid by any Lender), and if the portion to be so distributed to any
Lenders shall exceed the sum then due and payable to such Lenders, such excess
shall be held by the Administrative Agent in a collateral account for such
Lenders.

                   9.6 Non-Reliance on Administrative Agent and Other Lenders.
Each Lender expressly acknowledges that neither the Administrative Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates
has made any representations or warranties to it and that no act by the
Administrative Agent hereafter taken, including any review of the affairs of any
Loan Party, shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Lender. Each Lender represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of the Company and made its own decision to make its Loans
hereunder and enter into this Agreement. Each Lender also represents 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 credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigation as it deems necessary to inform
itself as to the business, operations, property, financial and other condition
and creditworthiness of the Borrowers. Each Lender acknowledges and agrees to
comply with the provisions of subsection 10.6 applicable to such Lender. Except
for notices, reports and other documents expressly required to be furnished to
the Lenders by the Administrative Agent hereunder, the Administrative Agent
shall not have any duty or responsibility to provide any Lender with any credit
or other information concerning the business, operations, property, condition
(financial or otherwise), prospects or creditworthiness of either Borrower which
may come into the possession of the Administrative Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or Affiliates.

                   9.7 Indemnification. The Lenders agree to indemnify the
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrowers and without limiting the obligation of the Borrowers and the other
Loan Parties to do so), ratably according to their respective Total Credit
Percentages in effect on the date on which indemnification is sought









                                       98

under this subsection (or, if indemnification is sought after the date upon
which the Revolving Credit Commitments and Canadian Revolving Credit
Commitments shall have terminated and the Loans shall have been paid in full,
ratably in accordance with their Total Credit Percentages immediately prior
to such date), from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind whatsoever which may at any time (including, without limitation, at
any time following the payment of the Loans) be imposed on, incurred by or
asserted against the Administrative Agent in any way relating to or arising
out of this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by the
Administrative Agent under or in connection with any of the foregoing;
provided that no Lender shall be liable for the payment of any portion of
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Administrative
Agent's gross negligence or willful misconduct. The obligations to indemnify
an Issuing Lender shall be ratable among the Revolving Credit Lenders, in the
case of the Revolving Credit Commitments, or the Canadian Revolving Credit
Lenders, in the case of the Canadian Revolving Credit Commitments, in accordance
with their respective Applicable Percentages (or, if the Commitments have been
terminated, the outstanding principal amount of their respective Total
Extensions of Credit). The agreements in this subsection shall survive the
payment of the Loans and all other amounts payable hereunder.

                   9.8 Administrative Agent in Its Individual Capacity. The
Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Borrowers and the other
Loan Parties as though the Administrative Agent were not the Administrative
Agent hereunder and under the other Loan Documents. With respect to its Loans
made or renewed by it and any Note issued to it and with respect to any Letter
of Credit issued or participated in by it, the Administrative Agent shall have
the same rights and powers under this Agreement and the other Loan Documents as
any Lender and may exercise the same as though it were not the Administrative
Agent, and the terms "Lender" and "Lenders" shall include the Administrative
Agent in its individual capacity.

                   9.9 Successor Administrative Agent. The Administrative Agent
may resign as Administrative Agent upon 30 days' notice to the Lenders and the
Company. If the Administrative Agent shall resign as Administrative Agent under
this Agreement and the other Loan Documents, then the Majority Facility Lenders
with respect to the Revolving Credit Facility shall appoint from among the
Revolving Credit Lenders a successor agent for such Lenders, which successor
agent shall be approved by the Company (such approval not to be unreasonable
withheld), whereupon such successor agent shall succeed to the rights, powers
and duties of the Administrative Agent, and the term "Administrative Agent"
shall mean such successor agent effective upon such appointment and approval,
and the former Administrative Agent's rights, powers and duties as
Administrative Agent shall be terminated, without any other or further act or
deed on the part of such former Administrative Agent or any of the parties to
this Agreement or any holders of the Loan. After any retiring Administrative
Agent's resignation as Administrative Agent, the provisions of this subsection
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Administrative Agent under this Agreement and the other Loan
Documents.









                                       99

                   9.10 Canadian Administrative Agent. Each Canadian Revolving
Credit Lender hereby irrevocably designates and appoints Chase Canada as the
Canadian Administrative Agent under this Agreement and the other Loan Documents,
and each such Canadian Revolving Credit Lender irrevocably authorizes Chase
Canada, as Canadian Administrative Agent for such Lender, to take such action on
its behalf under the provisions of the Agreement and the other Loan Documents
and to exercise such powers and perform such duties as are expressly delegated
to the Canadian Administrative Agent by the terms of this Agreement and the
other Loan Documents, together with such other provisions as are reasonably
incidental thereto. Each Canadian Revolving Credit Lender and the Borrowers
hereby agree and confirm that the provisions of this Section 9 shall apply to
Chase Canada as the Canadian Administrative Agent upon the same terms and
subject to the same conditions as apply to Chase in acting as Administrative
Agent and as Collateral Agent in this Section 9, mutatis mutandis; provided that
any successor Canadian Administrative Agent shall be a bank with an office in
Toronto, Canada having a combined capital and surplus of at least $500,000,000
or an Affiliate of any such bank which is also a Canadian Revolving Credit
Lender.

                   9.11 Documentation Agent and Syndication Agent. Neither the
Documentation Agent nor the Syndication Agent shall have any rights or
obligations under the Loan Documents in their capacities as such.

                            SECTION 10. MISCELLANEOUS

                   10.1 Amendments and Waivers. Neither this Agreement or any
other Loan Document, nor any terms hereof or thereof may be amended,
supplemented or modified except in accordance with the provisions of this
subsection. The Required Lenders may, or, with the written consent of the
Required Lenders, the Administrative Agent and the Canadian Administrative Agent
may, from time to time, (a) enter into with the Borrowers and the other Loan
Parties written amendments, supplements or modifications hereto and to the other
Loan Documents for the purpose of adding any provisions to this Agreement or the
other Loan Documents or changing in any manner the rights of the Lenders or of
the Borrowers and the other Loan Parties hereunder or thereunder or (b) waive,
on such terms and conditions as the Required Lenders or the Administrative
Agent, as the case may be, may specify in such instrument, any of the
requirements of this Agreement or the other Loan Documents or any Default or
Event of Default and its consequences; provided, however, that no such waiver
and no such amendment, supplement or modification shall:

                   (i) (x) reduce the amount or extend the scheduled date of
          maturity of any Loan or any Reimbursement Obligation or any Acceptance
          Reimbursement Obligation or of any scheduled installment thereof, or
          (y) reduce the stated rate of any interest or fee payable hereunder or
          extend the scheduled date of any payment thereof or increase the
          amount or (z) extend the expiration date of any Lender's Revolving
          Credit Commitment or Canadian Revolving Credit Commitment, in each
          case, without the written consent of each Lender directly affected
          thereby;









                                      100

                   (ii) amend, modify or waive any provision of subsection 9.5
          or this subsection 10.1 or reduce the percentage specified in the
          definition of Required Lenders, or consent to the assignment or
          transfer by any Loan Party of any of its rights and obligations under
          this Agreement and the other Loan Documents (other than pursuant to a
          transaction permitted by subsection 7.5), in each case, without the
          written consent of all the Lenders;

                   (iii) release the Company, the Canadian Borrower, any
          Subsidiary Guarantor, any Canadian Subsidiary Guarantor or any other
          Loan Party that is a Material Subsidiary from its obligations under
          any Security Document or release all or substantially all of the
          Collateral, in either case without the consent of each Lender, in each
          case except as expressly permitted hereby or by the other Loan
          Documents;

                   (iv) amend, modify or waive any provision of Section 9
          without the written consent of the then Administrative Agent and, if
          affected thereby, the Canadian Administrative Agent and the Designated
          Issuer;

                   (v) amend, modify or waive the order of application of
          prepayments specified in subsection 2.9(e) without the written consent
          of the Majority Facility Lenders under each Facility adversely
          affected thereby;

                   (vi) amend, modify or waive the provisions of Section 3, any
          Letter of Credit or any L/C Obligation without the written consent of

                   (vii) amend the first two sentences of subsection 2.15(a)
          without the written consent of each Lender adversely affected thereby.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Borrowers, the
Lenders, the Administrative Agent, the Canadian Administrative Agent and all
future holders of the Notes. In the case of any waiver, the Borrowers, the
Lenders, the Administrative Agent and the Canadian Administrative Agent shall be
restored to their former position and rights hereunder and under the outstanding
Notes and any other Loan Documents, and any Default or Event of Default waived
shall be deemed to be cured and not continuing; but no such waiver shall extend
to any subsequent or other Default or Event of Default, or impair any right
consequent thereon.

provided that any notice, request or demand to or upon the Administrative Agent,
the Issuing Banks or the Lenders pursuant to subsection 2.2, 2.3, 2.4, 2.8, 2.9,
2.10 or 3.2 shall not be effective until received.

                   10.3 No Waiver; Cumulative Remedies. No failure to exercise
and no delay in exercising, on the part of the Administrative Agent, the
Canadian Administrative Agent or any Lender, any right, remedy, power or
privilege hereunder or under the other Loan Documents shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

                   10.4 Survival of Representations and Warranties. All
representations and warranties made hereunder, in the other Loan Documents and
in any document, certificate or statement delivered pursuant hereto or in
connection herewith shall survive the execution and delivery of this Agreement
and the making of the extensions of credit hereunder.

                   10.5 Payment of Expenses and Taxes. The Borrowers agree (a)
to pay or reimburse the Administrative Agent, the Canadian Administrative Agent
and the Issuing Banks for all their reasonable out-of-pocket costs and expenses
incurred in connection with the development, preparation and execution of, and
any amendment, supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection herewith or therewith,
and the consummation and administration of the transactions contemplated hereby
and thereby, including, without limitation, the reasonable fees and
disbursements of counsel to the Administrative Agent, the Canadian
Administrative Agent and the Issuing Banks in the amounts agreed to with such
counsel, (b) to pay or reimburse the Issuing Banks, the Administrative Agent,
the Canadian Administrative Agent and, if a Default or an Event of Default shall
have occurred and be continuing, each Lender for all their reasonable
out-of-pocket costs and expenses incurred in connection with the enforcement or
preservation of any rights under this Agreement, the other Loan Documents and
any such other documents, including, without limitation, the reasonable fees and
disbursements of counsel to the Administrative Agent, to the Canadian
Administrative Agent, to the Issuing Banks and, if a









                                      103

Default or an Event of Default shall have occurred and be continuing, to the
several Lenders, (c) to pay, indemnify, and hold each Lender, the Issuing Banks,
the Administrative Agent and the Canadian Administrative Agent harmless from,
any and all recording and filing fees and any and all liabilities with respect
to, or resulting directly from any delay not caused by the Administrative Agent,
the Canadian Administrative Agent, any Issuing Bank or the Lenders in paying,
stamp, excise and other documentary taxes, if any, which may be payable or
determined to be payable in connection with the execution and delivery of,
or consummation or administration of any of the transactions contemplated by,
or any amendment, supplement or modification of, or any waiver or consent under
or in respect of, this Agreement, the other Loan Documents and any such other
documents, and (d) to pay, indemnify, and hold each Lender, the Issuing Banks,
the Administrative Agent and the Canadian Administrative Agent and each of
their officers, directors, employees and agents harmless from and against any
and all other liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, out-of-pocket expenses or disbursements of any kind
or nature whatsoever incurred in connection with the execution, delivery,
enforcement, performance and administration of this Agreement, the other Loan
Documents and any such other documents, including, without limitation, any of
the foregoing relating to the violation of, noncompliance with or liability
under, any Environmental Law applicable to the operations of Holdings, any of
its Subsidiaries or any of the Properties (all the foregoing in this clause
(d), collectively, the "indemnified liabilities"), provided, that the Borrowers
shall have no obligation hereunder to the Administrative Agent, the Canadian
Administrative Agent, any Issuing Bank, any Lender with respect to indemnified
liabilities arising from (i) the gross negligence or willful misconduct of the
Administrative Agent, the Canadian Administrative Agent, such Issuing Bank
or any such Lender (ii) legal proceedings commenced against the Administrative
Agent, the Canadian Administrative Agent, any Issuing Bank or any such Lender
by any security holder or creditor thereof arising out of and based upon rights
afforded any such security holder or creditor solely in its capacity as such or
(iii) legal proceedings commenced against the Administrative Agent, the Canadian
Administrative Agent, any Issuing Bank or any Lender by the Borrowers or any of
their Affiliates, in which the Borrowers or such Affiliate is the prevailing
party (unless the Administrative Agent, the Canadian Administrative Agent, such
Issuing Bank or such Lender is also a prevailing party, in which case the
indemnification obligations of the Borrowers hereunder shall be adjusted to
reflect the relative recoveries and faults of the parties to such litigation).
The Borrowers shall have no obligation under this subsection 10.5 for the
consequential damages of the Administrative Agent, the Canadian Administrative
Agent, any Issuing Bank any Lender. The agreements in this subsection shall
survive repayment of the Loans, and all other amounts payable hereunder.

                   10.6 Successors and Assigns; Participations and Assignments.
This Agreement shall be binding upon and inure to the benefit of the Borrowers,
the Lenders, the Issuing Banks, the Administrative Agent, the Canadian
Administrative Agent, all future holders of the Loans and their respective
successors and assigns, except that a Borrower may not assign or transfer any of
its rights or obligations under this Agreement (except in a transaction
permitted by subsection 7.5) without the prior written consent of each Lender.









                                      104

                   (b) Any Lender may, in the ordinary course of its business
and in accordance with applicable law, at any time sell to one or more banks or
other entities ("Participants") participating interests in any Loan owing to
such Lender, any Note held by such Lender, any Revolving Credit Commitment,
Canadian Revolving Credit Commitment or L/C Commitment of such Lender or any
other interest of such Lender hereunder and under the other Loan Documents. In
the event of any such sale by a Lender of a participating interest to a
Participant, such Lender's obligations under this Agreement to the other parties
to this Agreement shall remain unchanged, such Lender shall remain solely
responsible for the performance thereof, such Lender shall remain the holder of
any such Note for all purposes under this Agreement and the other Loan
Documents, and the Borrowers, the Administrative Agent and the Canadian
Administrative Agent shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under this Agreement and
the other Loan Documents; provided that such Lender shall reserve solely unto
itself, and shall not grant to any Participant, any part or all of its right to
agree to the amendment, modification or waiver of any of the terms of this
Agreement or other Loan Document or any document related thereto, except for any
such amendment, modification or waiver that would reduce the principal of, or
interest on the Loans, participating interests in the Letters of Credit or any
fees payable hereunder, in each case subject to such participation, or postpone
the date of the final maturity of, or any scheduled date fixed for payment of
interest on, the Loans, any Reimbursement Obligation or any Acceptance
Reimbursement Obligation, in each case to the extent subject to such
participation. Each Borrower agrees that if amounts outstanding under this
Agreement are due or unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall, to the maximum extent permitted by applicable law, be deemed to have the
right of setoff in respect of its participating interest in amounts owing under
this Agreement to the same extent as if the amount of its participating interest
were owing directly to it as a Lender under this Agreement or any Note, provided
that, in purchasing such participating interest, such Participant shall be
deemed to have agreed to share with the Lenders the proceeds thereof as provided
in subsection 10.7(a) as fully as if it were a Lender hereunder. Each Borrower
also agrees that each Participant shall be entitled to the benefits of
subsections 2.17, 2.18 and 2.19 with respect to its participation in the
Commitments and the Loans outstanding from time to time as if it were a Lender;
provided that, in the case of subsection 2.18, such Participant shall have
complied with the requirements of said subsection as if it were a Lender, except
with respect to the furnishing of forms, documentation and certifications, in
which case such Participant shall have complied with the requirements of
subsection 2.18(b), and provided, further, that no Participant shall be entitled
to receive any greater amount pursuant to any such subsection 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.

                   (c) Any Lender may, in accordance with applicable law, at any
time and from time to time assign to any Lender or any Affiliate thereof, or,
with the consent of the Company, the applicable Issuing Banks and the
Administrative Agent (which in each case shall not be unreasonably withheld), to
an additional bank, fund (as long as such fund invests in bank loans) or other
financial institution (an "Assignee") all or any part of its rights and
obligations under this Agreement pursuant to an Assignment and Acceptance,
substantially in the form of Exhibit 








                                      105

C, executed by such Assignee, such assigning Lender (and, in the case of an
Assignee that is not then a Lender or an Affiliate thereof, by the Company,
the applicable Issuing Banks and the Administrative Agent) and delivered to
the Administrative Agent (which shall deliver a copy to the Canadian
Administrative Agent) for its acceptance and recording in the Register. Any
such assignment by any Lender to any Person which is not then a Lender or an
Affiliate thereof shall be in a minimum aggregate amount equal to at least
$5,000,000 (or the Dollar Equivalent Amount with respect thereto) (or, if
less, all of a Lender's interest under this Agreement), unless otherwise
agreed by the Company and the Administrative Agent, and, after giving effect
to any such assignment, the assigning Lender and its Affiliates shall have
Commitments of at least $5,000,000, unless otherwise agreed by the Company
and the Administrative Agent. Interests under the Canadian Revolving
Credit Commitments may be assigned only to Canadian Scheduled Lenders.
Notwithstanding any other provision of this subsection 10.6, (i) no Canadian
Schedule I Lender having both a Revolving Credit Commitment and a Canadian
Revolving Credit Commitment shall be permitted to assign any portion of its
interests under this Agreement unless, after giving effect to such assignment,
such Lender shall be able to comply with a reallocation of Commitments pursuant
to subsection 2.4, (ii) no Lender may assign any portion of its interests under
this Agreement unless, after giving effect to such assignment, such Lender,
together with its affiliated Allocation Lender, shall be able to comply with a
reallocation of Commitments pursuant to subsection 2.4 and (iii) no Assignee
shall receive any assignment of rights and obligations under this Agreement
unless, after giving effect to such assignment, such Assignee (or such Assignee
together with a Lender that is an Affiliate thereof) shall be able to comply
with a reallocation of Commitments pursuant to subsection 2.4. Upon such
execution, delivery, acceptance and recording, from and after the effective date
determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Credit Commitment and/or Canadian Revolving Credit Commitments
as set forth therein, and (y) the assigning Lender thereunder shall, to the
extent provided in such Assignment and Acceptance, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such assigning Lender shall cease to be a
party hereto). Notwithstanding any provision of this subsection to the contrary,
the consent of the Company to an assignment shall not be required at any time
when an Event of Default under paragraph (a) or (n) of subsection 8.1 shall have
occurred and be continuing.

                   (d) Each of the Administrative Agent and the Canadian
Administrative Agent shall maintain at its address referred to in subsection
10.2 a copy of each Assignment and Acceptance delivered to it and a register
(the "Register") for the recordation of the names and addresses of the Lenders
and the Commitment of, and principal amount of the Loans owing to, each Lender
from time to time. The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrowers, the Administrative Agent, the
Canadian Administrative Agent and the Lenders may treat each Person whose name
is recorded in the Register as the owner of the Loans and any Notes evidencing
such Loans recorded therein for all purposes of this Agreement. Any assignment
of any Loan, whether or not evidenced by a Note, shall be effective only upon
appropriate entries with respect thereto being made in the Register (and each
Note shall expressly so provide). Any assignment or transfer of all or part of a
Loan evidenced by a








                                      106

Note shall be registered on the Register only upon surrender for registration
of assignment or transfer of the Note evidencing such Loan, accompanied by
a duly executed Assignment and Acceptance; thereupon one or more new Notes
in the same aggregate principal amount shall be issued to the designated
Assignee, and the old Notes shall be returned by the Administrative Agent
to the Company marked "cancelled". The Register shall be available for
inspection by the Borrowers or any Lender at any reasonable time and from time
to time upon reasonable prior notice. It is understood that the Canadian
Administrative Agent shall be required to maintain the Register only with
respect to the Canadian Revolving Credit Commitments and the Administrative
Agent may, but shall not be required to, maintain the Register with respect to
Canadian Revolving Credit Commitments and extensions of credit thereunder.

                   (e) Upon its receipt of an Assignment and Acceptance executed
by an assigning Lender and an Assignee (and, in the case of an Assignee that is
not then a Lender or an Affiliate thereof, by the Company, the applicable
Issuing Banks and the Administrative Agent) together with payment to the
Administrative Agent of a registration and processing fee of $3,500 (which the
fee shall not be payable in connection with an assignment by a Lender to an
Affiliate thereof), the Administrative Agent shall (i) promptly accept such
Assignment and Acceptance and (ii) on the effective date determined pursuant
thereto record the information contained therein in the Register and give notice
of such acceptance and recordation to the Borrowers. On or prior to such
effective date, the applicable Borrower, at its own expense, upon request, shall
execute and deliver to the Administrative Agent or the Canadian Administrative
Agent, as the case may be (in exchange for the Notes of the assigning Lender),
new Notes to the order of such Assignee in an amount equal to the Revolving
Credit Commitment and/or Canadian Revolving Credit Commitment, as the case may
be, assumed or acquired by it pursuant to such Assignment and Acceptance and, if
the assigning Lender has retained a Revolving Credit Commitment and/or Canadian
Revolving Credit Commitment, as the case may be, upon request, new Notes to the
order of the assigning Lender in an amount equal to the Revolving Credit
Commitment and/or Canadian Revolving Credit Commitment, as the case may be,
retained by it hereunder. Such new Notes shall be dated the Effective Date and
shall otherwise be in the form of the Notes replaced thereby.

                   (f) Each Borrower authorizes each Lender to disclose to any
Participant or Assignee (each, a "Transferee") and any prospective Transferee,
subject to the provisions of subsection 10.15, any and all financial information
in such Lender's possession concerning the Borrowers and their Affiliates which
has been delivered to such Lender by or on behalf of the Borrowers pursuant to
this Agreement or which has been delivered to such Lender by or on behalf of the
Borrowers in connection with such Lender's credit evaluation of the Borrowers
and their Affiliates prior to becoming a party to this Agreement.

                   (g) For avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this subsection concerning assignments of
Loans and Notes relate only to absolute assignments and that such provisions do
not prohibit assignments creating security interests, including, without
limitation, any pledge or assignment by a Lender of any Loan or Note to any
Federal Reserve Bank in accordance with applicable law.









                                      107

                   10.7 Adjustments; Set-off. Except to the extent that this
Agreement and the other Loan Documents provide for payments to be allocated to a
particular Lender or to the Lenders under a particular Facility, if any Lender
(a "Benefitted Lender") shall at any time receive any payment of all or part of
the Obligations owing to it, or receive any collateral in respect thereof
(whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in subsection 8.1(n), or otherwise), in a
greater proportion than any such payment to or collateral received by any other
Lender, if any, in respect of such other Lender's Obligations, such Benefitted
Lender shall purchase for cash from the other Lenders a participating interest
in such portion of each such other Lender's Obligations, or shall provide such
other Lenders with the benefits of any such collateral, or the proceeds thereof,
as shall be necessary to cause such Benefitted Lender to share the excess
payment or benefits of such collateral or proceeds ratably with each of the
Lenders; provided, however, that if all or any portion of such excess payment or
benefits is thereafter recovered from such Benefitted Lender, such purchase
shall be rescinded, and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

                   (b) In addition to any rights and remedies of the Lenders
provided by law so long as a Default or an Event of Default shall have occurred
and be continuing, each Lender shall have the right, without prior notice to the
Borrowers, any such notice being expressly waived by each Borrower to the extent
permitted by applicable law, upon any amount becoming due and payable by either
Borrower hereunder (whether at the stated maturity, by acceleration or
otherwise) to set-off and appropriate and apply against such amount any and all
deposits (general or special, time or demand, provisional or final), in any
currency, and any other credits, indebtedness or claims, in any currency, in
each case whether direct or indirect, absolute or contingent, matured or
unmatured, at any time held or owing by such Lender or any branch or agency
thereof to or for the credit or the account of such Borrower. Each Lender agrees
promptly to notify the applicable Borrower and the Administrative Agent after
any such set-off and application made by such Lender, provided that the failure
to give such notice shall not affect the validity of such set-off and
application.

                   10.8 Counterparts. This Agreement may be executed by one or
more of the parties to this Agreement on any number of separate counterparts
(including by telecopy), and all of said counterparts taken together shall be
deemed to constitute one and the same instrument. A set of the copies of this
Agreement signed by all the parties shall be lodged with the Company and the
Administrative Agent.

                   10.9 Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                   10.10 Integration. This Agreement and the other Loan
Documents represent the agreement of the Borrowers, the Agents, the Issuing
Banks and the Lenders with respect to the subject matter hereof, and there are
no promises, undertakings, representations or warranties by







                                      108

the Agents, the Issuing Banks or any Lender relative to subject matter hereof
not expressly set forth or referred to herein or in the other Loan Documents.

                   10.11 GOVERNING LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS (UNLESS EXPRESSLY STATED OTHERWISE IN A LOAN DOCUMENT) AND THE RIGHTS
AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
(UNLESS EXPRESSLY STATED OTHERWISE IN A LOAN DOCUMENT) SHALL BE GOVERNED BY, AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

                   10.12 Submission To Jurisdiction; Waivers. Each Borrower
hereby irrevocably and unconditionally:

                   (a) submits for itself and its property in any legal action
          or proceeding relating to this Agreement and the other Loan Documents
          to which it is a party, or for recognition and enforcement of any
          judgement in respect thereof, to the non-exclusive general
          jurisdiction of the Courts of the State of New York, the courts of the
          United States of America for the Southern District of New York, and
          appellate courts from any thereof and the courts of the Province of
          Ontario;

                   (b) consents that any such action or proceeding may be
          brought in such courts and waives any objection that it may now or
          hereafter have to the venue of any such action or proceeding in any
          such court or that such action or proceeding was brought in an
          inconvenient court and agrees not to plead or claim the same;

                   (c) agrees that service of process in any such action or
          proceeding may be effected by mailing a copy thereof by registered or
          certified mail (or any substantially similar form of mail), postage
          prepaid, to such Borrower at its address set forth in subsection 10.2
          or at such other address of which the Administrative Agent or the
          Canadian Administrative Agent, as the case may be, shall have been
          notified pursuant thereto;

                   (d) agrees that nothing herein shall affect the right to 
          effect service of process in any other manner permitted by law or 
          shall limit the right to sue in any other jurisdiction; and

                   (e) waives, to the maximum extent not prohibited by law, any
          right it may have to claim or recover in any legal action or
          proceeding referred to in this subsection any special, exemplary,
          punitive or consequential damages; provided that any such waiver shall
          not apply with respect to claims arising from the gross negligence or
          willful misconduct of the Administrative Agent, the Canadian
          Administrative Agent, any Issuing Bank or any Lender.

                   10.13 Acknowledgments. Each Borrower hereby acknowledges








                                      109

that:

                   (a) it has been advised by counsel in the negotiation,
          execution and delivery of this Agreement and the other Loan Documents;

                   (b) neither the Administrative Agent, the Canadian
          Administrative Agent nor any Lender has any fiduciary relationship
          with or duty to either Borrower arising out of or in connection with
          this Agreement or any of the other Loan Documents, and the
          relationship between Administrative Agent, the Canadian Administrative
          Agent and Lenders, on one hand, and the Borrowers, on the other hand,
          in connection herewith or therewith is solely that of debtor and
          creditor; and

                   (c) no joint venture is created hereby or by the other Loan
          Documents or otherwise exists by virtue of the transactions
          contemplated hereby among the Lenders or among the Borrowers and the
          Lenders.

                   10.14 WAIVERS OF JURY TRIAL. EACH BORROWER, THE
ADMINISTRATIVE AGENT, THE CANADIAN ADMINISTRATIVE AGENT, THE ISSUING BANKS AND
THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY
LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR THE NOTES OR ANY OTHER
LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

                   10.15 Confidentiality. Each Lender agrees to keep
confidential all non-public information provided to it by either Borrower or any
Loan Party pursuant to this Agreement or any Loan Document or in connection with
the transactions contemplated by this Agreement or any Loan Document that is
designated by a Borrower in writing as confidential; provided that nothing
herein shall prevent any Lender from disclosing any such information (i) to the
Administrative Agent, the Canadian Administrative Agent or any other Lender,
(ii) to any Transferee which executes a Confidentiality Agreement substantially
in the form of Exhibit D hereto, (iii) to its employees, directors, agents,
attorneys, accountants and other professional advisors, (iv) upon the request or
demand of any Governmental Authority (including, without limitation, the
National Association of Insurance Commissioners) having jurisdiction over such
Lender, (v) in response to any order of any court or other Governmental
Authority or as may otherwise be required pursuant to any Requirement of Law,
(vi) which has been publicly disclosed other than in breach by such Lender of
this Agreement, (vii) in connection with the exercise of any remedy hereunder,
(viii) in connection with periodic regulatory examinations, (ix) in connection
with any litigation to which such Lender may be a party, (x) to any direct or
indirect contractual counterparty in swap agreements or such contractual
counterparty's professional advisor (so long as such contractual counterparty or
professional advisor to such contractual counterparty (A) has been approved in
writing by the Company and (B) agrees in a writing enforceable by the Company to
be bound by the provisions of this subsection 10.15) and (xi) if, prior to such
information having been so provided or obtained, such information was already in
the Administrative Agent's, the Canadian Administrative Agent's, or a Lender's
possession on a nonconfidential basis without a duty of confidentiality to such
Borrower or any Loan Party being violated.

                   10.16 Conversion of Currencies. (a) If, for the purpose of
obtaining judgment in any court, it is necessary to convert a sum due hereunder
or under any other Loan Document in Dollars or Canadian Dollars into another
currency, the parties hereto agree, to the fullest extent that they may legally
and effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Administrative Agent or the
Canadian Administrative Agent, as the case may be, could purchase Dollars or
Canadian Dollars, as the case may be, with such other currency in New York, New
York or Toronto, Canada, as the case may be, on the Business Day immediately
preceding the day on which final judgment is given.

                   (b) The obligation of each Borrower in respect of any sum due
to the Administrative Agent, the Canadian Administrative Agent, any Lender or
any Issuing Bank hereunder or under any other Loan Document in Dollars shall, to
the extent permitted by applicable law, notwithstanding any judgment in a
currency other than Dollars, be discharged only to the extent that on the
Business Day following receipt of any sum adjudged to be so due in the judgment
currency the Administrative Agent, the Canadian Administrative Agent, such
Lender or such Issuing Bank may in accordance with normal banking procedures
purchase Dollars in the amount originally due to the Administrative Agent, the
Canadian Administrative Agent, such Lender or such Issuing Bank with the
judgment currency. If the amount of Dollars so purchased is less than the sum
originally due to the Administrative Agent, the Canadian Administrative Agent,
such Lender or such Issuing Bank, the applicable Borrower agrees, as a separate
obligation and notwithstanding any such judgment, to indemnify the
Administrative Agent, the Canadian Administrative Agent, such Lender or such
Issuing Bank against the resulting loss, and if the amount of Dollars so
purchased exceeds the sum originally due to such Person in Dollars, such Person
shall permit such excess to the Company.

                   (c) The obligation of each Borrower in respect of any sum due
to the Canadian Administrative Agent, the Administrative Agent, any Canadian
Revolving Credit Lender or any Issuing Bank hereunder or under any other Loan
Document in Canadian Dollars shall, to the extent permitted by applicable law,
notwithstanding any judgment in a currency other than Canadian Dollars, be
discharged only to the extent that on the Business Day following receipt of any
sum adjudged to be so due in the judgment currency the Canadian Administrative
Agent, the Administrative Agent, such Canadian Revolving Credit Lender or such
Issuing Bank may in accordance with normal banking procedures purchase Canadian
Dollars in the amount originally due to the Canadian Administrative Agent, the
Administrative Agent, such Canadian Revolving Credit Lender or such Issuing Bank
with the judgment currency. If the amount of Canadian Dollars so purchased is
less than the sum originally due to the Canadian Administrative Agent, the
Administrative Agent, such Canadian Revolving Credit Lender or such Issuing
Bank, each Borrower agrees, as a separate obligation and notwithstanding any
such judgment, to indemnify the Canadian Administrative Agent, the
Administrative Agent, such Canadian Revolving Credit Lender or such Issuing Bank
against the resulting loss.

Changes in the Applicable Margin and Commitment Fee Rate resulting from changes
in the Pricing Ratio (as defined below) shall become effective on the date (the
"Adjustment Date") on which financial statements are delivered to the Lenders
pursuant to subsection 6.1 (but in any event not later than the 60th day after
the end of each of the first three quarterly periods of each fiscal year or the
90th day after the end of each fiscal year, as the case may be), beginning with
the financial statements delivered for the fiscal quarter ending December 31,
1999, and shall remain in effect until the next change to be effected pursuant
to this paragraph. If any financial statements referred to above are not
delivered within the time periods specified above, then, until such financial
statements are delivered, the Pricing Ratio as at the end of the fiscal period
that would have been covered thereby shall for the purposes of this definition
be deemed to be greater than 5.25 to 1. In addition, at all times while an Event
of Default shall have occurred and be continuing, the Pricing Ratio shall for
the purposes of this definition be deemed to be greater than 5.25 to 1. Each
determination of the Pricing Ratio pursuant to this definition shall be made
with respect to the period of four consecutive fiscal quarters of the Company
ending at the end of the period covered by the relevant financial statements.

"Pricing Ratio" means, as at the last day of any fiscal quarter of the Company,
the Pro Forma Ratio of (a) Funded Debt as at such day to (b) Consolidated Cash
Flow for the period of four fiscal quarters ending on such day.

"Funded Debt" means, as to any Person, all Indebtedness of such Person that
matures more than one year from the date of its creation or matures within one
year from such date but is renewable or extendible, at the option of such
Person, to a date more than one year from such date or arises under a revolving
credit or similar agreement that obligates the lender or lenders to extend
credit during a period of more than one year from such date, including all
current maturities and current






sinking fund payments in respect of such Indebtedness whether or not required
to be paid within one year from the date of its creation and, in the case of
a Borrower, Indebtedness in respect of the Loans. Notwithstanding anything
in the foregoing to the contrary, Funded Debt shall exclude Indebtedness and
Guarantee Obligations of a Person in respect of reclamation bonds, performance
bonds, letters of credit and surety bonds required by the applicable statutes
or laws of the relevant jurisdiction or by relevant Government Authorities
(or, in the case of such letters of credit, issued for insurance purposes).
